From ab590202b511663e74c390695ce74f508e8a1f10 Mon Sep 17 00:00:00 2001 From: acer_feng <857688528@qq.com> Date: Fri, 2 Oct 2026 01:07:29 +0800 Subject: [PATCH 01/64] docs(webui): the engine layer has six files, not five (webui-parity 107) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ARCHITECTURE.md:492 counted five files under server/engine/ while the directory has shipped six since #143. The missing one is providers/local-runtime-v2.capabilities.js, the declaration-only module whose sole import is ../capabilities.js — the split that keeps the v2 host's ~4.7 s TypeScript dependency tree off the boot path. The local-runtime-v2.js row credited itself with the declaration it only re-exports, so that credit moves to the file that actually defines it. The zh-CN mirror takes the same edit in the same commit (equal weight); check-docs-alignment.mjs resolves the new bare-path citation against the merged tree. --- packages/webui/docs/ARCHITECTURE.md | 5 +++-- packages/webui/docs/ARCHITECTURE.zh-CN.md | 5 +++-- 2 files changed, 6 insertions(+), 4 deletions(-) diff --git a/packages/webui/docs/ARCHITECTURE.md b/packages/webui/docs/ARCHITECTURE.md index 6a2638c4..c11d66f5 100644 --- a/packages/webui/docs/ARCHITECTURE.md +++ b/packages/webui/docs/ARCHITECTURE.md @@ -489,14 +489,15 @@ not import it but adopts the same shape.

They now call getEngineCatalogueHost() from the facade. - engine/host.js: the lazy bridge. Its only import is a dynamic `await import("../lib/acp-client.js")` inside the function body, so engine/index.js gains a function and not a module load. That boundary is the whole point: app.js reaches engine/index.js through routes/engine-capabilities.js, and a static import of acp-client there would put the ACP client tree on every server start — the regression M1 paid for once (209ms -> 2700ms; facade load 4685ms -> 5ms once declaration and construction were split). The value is forwarded verbatim, `null` included, so "host did not boot" stays RUNTIME_UNAVAILABLE and never a second host. - engine/index.js re-exports the getter; the two routes import it from there and no longer name acp-client.js. - No endpoint behaviour changes: same wire shapes, statuses, codes, same `deps.getCliService` / `deps.getDiffApplication` seams, same one process-wide host. Measured on the module graph: routes/plugins.js drops from 13 product files + @mavis/shared to 8 files and zero bare packages; engine/index.js's whole closure is 6 files and 0 bare specifiers. Server start and the facade's own load are unchanged (facade ~1.2ms -> ~3ms, i.e. one more 45-line zero-import file; boot stays in the same 200-300ms band) because lib/state-bus.js already pulls acp-client into app.js's boot graph — closing that edge belongs to the catalogue read/write batches (M3-B1+), not here. Tests: test/lib/engine/host-facade.test.js pins the contract against the real module graph rather than against source text — a resolve hook (module.registerHooks) in a fresh process reports, per parent, which specifiers each entry resolved. It asserts neither route has a direct edge to acp-client/runtime-host/acp.mjs, that loading engine/index.js pulls no host module and no @mavis/* or @minimax/* package, that engine/host.js is in that closure, and the source-shape tripwires (dynamic import only, facade re-export). Mutation-checked: making the facade import statically turns 4 tests red, making plugins.js import directly turns 4 more red. The existing plugins/turn-diff suites pass unchanged under both transports (158 tests x acp and x runtime). Docs: ARCHITECTURE.md + .zh-CN.md — the engine/ file table gains engine/host.js on top of the six files #143 + the doc batch settled, the "one host" rule now names the facade, and the boot-path discipline is stated where the file list lives. docs/webui.md + .zh-CN.md are untouched: no user-visible change.

A caller that exports MCODE_WEBUI_SESSIONS_DB redirects the store, while the suite's beforeEach still cleared join(DATA_DIR, "sessions.json") — so each run read the previous run's records and the mid-run switch resolved an id whose workspace belonged to a since-removed tmp dir.

They now call getEngineCatalogueHost() from the facade. - engine/host.js: the lazy bridge. Its only import is a dynamic `await import("../lib/acp-client.js")` inside the function body, so engine/index.js gains a function and not a module load. That boundary is the whole point: app.js reaches engine/index.js through routes/engine-capabilities.js, and a static import of acp-client there would put the ACP client tree on every server start — the regression M1 paid for once (209ms -> 2700ms; facade load 4685ms -> 5ms once declaration and construction were split). The value is forwarded verbatim, `null` included, so "host did not boot" stays RUNTIME_UNAVAILABLE and never a second host. - engine/index.js re-exports the getter; the two routes import it from there and no longer name acp-client.js. - No endpoint behaviour changes: same wire shapes, statuses, codes, same `deps.getCliService` / `deps.getDiffApplication` seams, same one process-wide host. Measured on the module graph: routes/plugins.js drops from 13 product files + @mavis/shared to 8 files and zero bare packages; engine/index.js's whole closure is 6 files and 0 bare specifiers. Server start and the facade's own load are unchanged (facade ~1.2ms -> ~3ms, i.e. one more 45-line zero-import file; boot stays in the same 200-300ms band) because lib/state-bus.js already pulls acp-client into app.js's boot graph — closing that edge belongs to the catalogue read/write batches (M3-B1+), not here. Tests: test/lib/engine/host-facade.test.js pins the contract against the real module graph rather than against source text — a resolve hook (module.registerHooks) in a fresh process reports, per parent, which specifiers each entry resolved. It asserts neither route has a direct edge to acp-client/runtime-host/acp.mjs, that loading engine/index.js pulls no host module and no @mavis/* or @minimax/* package, that engine/host.js is in that closure, and the source-shape tripwires (dynamic import only, facade re-export). Mutation-checked: making the facade import statically turns 4 tests red, making plugins.js import directly turns 4 more red. The existing plugins/turn-diff suites pass unchanged under both transports (158 tests x acp and x runtime). Docs: ARCHITECTURE.md + .zh-CN.md — the engine/ file table gains engine/host.js on top of the six files #143 + the doc batch settled, the "one host" rule now names the facade, and the boot-path discipline is stated where the file list lives. docs/webui.md + .zh-CN.md are untouched: no user-visible change. Source inventory regenerated for the two new files (rebase conflict in it was resolved by taking the upstream copy and regenerating, never by hand).

MAVIS_DATA_DIR, so the gate's MINIMAX_DATA_DIR outranked mavis-usage.check.mjs's own MAVIS_DATA_DIR fixture and every DB-backed case resolved null against a scratch dir that holds no runtime-state.sqlite. The suite now exports the name that wins. - config.js resolves SESSIONS_DB as MCODE_WEBUI_SESSIONS_DB || join(WEBUI_DATA_DIR, "sessions.json"). A caller that exports MCODE_WEBUI_SESSIONS_DB redirects the store, while the suite's beforeEach still cleared join(DATA_DIR, "sessions.json") — so each run read the previous run's records and the mid-run switch resolved an id whose workspace belonged to a since-removed tmp dir. Both chat-route suites now pin MCODE_WEBUI_SESSIONS_DB to the same path their cleanup clears. Test-only: no server/ code, no helper under test/helpers/_setup.js, and no assertion weakened or skipped. Verified with the three variables set, with MCODE_WEBUI_SESSIONS_DB additionally set, and bare. From e7c0ce935b003ad8c07cad704250d107da2db077 Mon Sep 17 00:00:00 2001 From: acer_feng <857688528@qq.com> Date: Fri, 2 Oct 2026 01:57:19 +0800 Subject: [PATCH 09/64] feat(webui): the five read endpoints ask the engine facade, not the transport (M3-B1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The directory-read family — #9 acp-sessions, #10 acp-session-title, #72 protocol/list-sessions, #74 state, #75 health — reached the engine through whatever MCODE_WEBUI_TRANSPORT happened to be, so "does the engine support this" had no answer anywhere except the absence of a crash. server/engine/ session-reads.js gives it one: each endpoint declares the capability and the provider method it needs, the facade checks the registered provider's declaration first, and a provider that does not offer the read answers 501 through invokeHandler instead of an empty list. Nothing on the wire moves. The facade forwards to the same acp-client exports the routes already called, so the 30s cache, the cwd normalisation, the 30s-stale sidebar push semantics and the catalogue-sessions projection are the same code; handleHealth becomes async because the version now resolves through the facade, which is why app-hono's legacy-parity helper learned to await it. /api/state's snapshot field list is untouched — snapshotViewFields and mcodeSessionsSnapshotFields are the first-frame render contract and this batch adds and removes nothing. Each read also reports where its bytes came from — catalogue, acp, or acp-fallback when the runtime transport asked for a host that never booted. That is metadata, not wire, and it is the difference between a sidebar that degraded and one that pretends. Two things this batch found rather than assumed: the catalogue host exposes no version accessor, so /api/health keeps answering from the ACP initialize mirror and says so rather than inventing a method; and protocol.js#72's old test drove a mock key nothing read, so "the cwd filter works" had never actually been proven. --- packages/webui/docs/ARCHITECTURE.md | 44 +- packages/webui/docs/ARCHITECTURE.zh-CN.md | 39 +- packages/webui/server/engine/index.js | 22 + packages/webui/server/engine/session-reads.js | 302 +++++++++++ packages/webui/server/routes/health.js | 26 +- packages/webui/server/routes/protocol.js | 19 +- packages/webui/server/routes/sessions.js | 29 +- packages/webui/server/routes/state.js | 28 +- packages/webui/test/helpers/_setup.js | 9 + .../test/lib/engine/session-reads.test.js | 486 ++++++++++++++++++ packages/webui/test/routes/health.check.mjs | 67 ++- packages/webui/test/routes/protocol.check.mjs | 53 +- .../webui/test/routes/session-reads.check.mjs | 464 +++++++++++++++++ packages/webui/test/server/app-hono.test.js | 19 +- release/public-source.json | 3 + 15 files changed, 1547 insertions(+), 63 deletions(-) create mode 100644 packages/webui/server/engine/session-reads.js create mode 100644 packages/webui/test/lib/engine/session-reads.test.js create mode 100644 packages/webui/test/routes/session-reads.check.mjs diff --git a/packages/webui/docs/ARCHITECTURE.md b/packages/webui/docs/ARCHITECTURE.md index 30968c00..67749444 100644 --- a/packages/webui/docs/ARCHITECTURE.md +++ b/packages/webui/docs/ARCHITECTURE.md @@ -489,7 +489,7 @@ not import it but adopts the same shape.

The two families are separate files because their gate policies are opposite. The tree is entirely engine data, so a provider that cannot list sessions genuinely has no tree: assertSessionTreeCapability throws and invokeHandler answers 501. Export's primary source is sessions.json and the engine only contributes a best-effort transcript enrichment the endpoint has always promised never to block on, so checkSessionExportCapability reports and never throws — gating it hard would delete working functionality in response to a declaration about a capability the endpoint does not depend on. The tree route re-throws the capability error, matched with the class's own instanceof helper rather than a `.name` compare: `name` is a writable instance property, so a stray `err.name = "…"` would silently turn that 501 back into the 200 soft-fail the gate exists to prevent. A test pins both halves — the real class propagates, an impostor carrying the right `.name` does not. Verified by exporting the real tree (303 rows, 32 projects, 299 nodes) before and after and diffing every node's id/title/parent/depth: 3289 field comparisons, zero differences. A synthetic fixture covers what the live data does not contain (orphans, cycles, four-level nesting, exotic titles): 165 comparisons, zero differences. Two pre-existing shapes are pinned because a "cleanup" would silently break them — child nodes carry no `children` key (all 66 of them), and the response has no parent_session_id key at all. --- packages/webui/docs/ARCHITECTURE.md | 76 +- packages/webui/docs/ARCHITECTURE.zh-CN.md | 64 +- packages/webui/server/engine/index.js | 21 + .../webui/server/engine/session-export.js | 235 +++++ .../webui/server/engine/session-tree-reads.js | 220 +++++ packages/webui/server/routes/export.js | 28 +- packages/webui/server/routes/sessions.js | 41 +- .../test/lib/engine/session-export.test.js | 600 ++++++++++++ .../lib/engine/session-tree-reads.test.js | 854 ++++++++++++++++++ release/public-source.json | 4 + 10 files changed, 2124 insertions(+), 19 deletions(-) create mode 100644 packages/webui/server/engine/session-export.js create mode 100644 packages/webui/server/engine/session-tree-reads.js create mode 100644 packages/webui/test/lib/engine/session-export.test.js create mode 100644 packages/webui/test/lib/engine/session-tree-reads.test.js diff --git a/packages/webui/docs/ARCHITECTURE.md b/packages/webui/docs/ARCHITECTURE.md index 67749444..8f195b72 100644 --- a/packages/webui/docs/ARCHITECTURE.md +++ b/packages/webui/docs/ARCHITECTURE.md @@ -489,7 +489,7 @@ not import it but adopts the same shape.

The NODE SHAPE. The wire node is exactly +// `{id, title, agent, kind, status, updatedAt, children}` — and in +// particular it carries NO `parent_session_id` key. The hierarchy is +// structural (via `children`), not a field on the node. The batch +// brief asked whether such a key is omitted or `null`; the truthful +// answer, measured against the real 299-node tree before the +// refactor, is that the key does not exist at all. The key SET is +// asserted exactly, not by subset, so both halves stay honest. +// 2. The HIERARCHY FILTER. `buildTree` attaches a child to the root +// session named by its `parent_session_id`, in the SAME directory. +// Anything that does not attach — an orphan (parent not in the row +// set), a cross-directory parent, a grandchild whose parent is +// itself a child, a child of a `root` container row, anything in a +// cycle — is DROPPED SILENTLY.

The GATE IS REAL. #8 is 100% engine data, so a provider that +// declares no session listing must produce +// EngineCapabilityNotSupportedError → 501, never an empty tree +// (#110 fake-success). And the route must PROPAGATE that error +// rather than folding it into its own `{ok:false}` soft-fail body — +// that propagation is the one place this batch could have turned a +// 501 into a 200, so it has its own test. +// +// Boundaries probed empirically against the PRE-refactor route, not +// assumed from the batch plan (which was wrong on this point): #8 reads +// exactly one query parameter, `refresh`. `limit`, `offset`, `page` and +// `cursor` are NOT read — `?limit=1` returns the whole tree.

Three modules because the three gate policies are all different: the account read gates HARD on authCredentials.getAccountStatus (the same provider method B3's #15/#16 read, so a provider that drops it takes both down together), the model catalogue gates SOFT (its primary sources are files webui owns, so a hard gate would delete a working picker), and #73 declares nothing at all because it IS the declaration endpoint. The model projection moved whole — three sources, the per-provider dedupe, both builtin-tree annotations and the three derived figures are now named pure functions pinned on their inputs, and #57 is verified by a full snapshot whose oracle was captured from the pre-refactor implementation. Its read stays synchronous so handleGetModels keeps its contract, which is also why engine/model-reads.js is not re-exported from engine/index.js: its four sources reach @mavis/shared and js-yaml, and the boot-path guard is right to refuse that under the shared facade. #73 is the one response body in the migration that changes: it gains an `engine` key carrying the engine-capabilities view, with `providerFor` saying whether the declaration came from the active transport's provider or from the default one standing in. Every pre-existing key keeps its name, position and value, and the ACP wire table is not replaced by the 14 matrix keys. --- packages/webui/docs/API.md | 49 +- packages/webui/docs/API.zh-CN.md | 46 +- packages/webui/docs/ARCHITECTURE.md | 122 +- packages/webui/docs/ARCHITECTURE.zh-CN.md | 104 +- .../webui/scripts/check-docs-alignment.mjs | 2 + packages/webui/server/engine/account-reads.js | 228 ++++ .../webui/server/engine/capability-reads.js | 216 +++ packages/webui/server/engine/index.js | 61 +- packages/webui/server/engine/model-reads.js | 727 ++++++++++ packages/webui/server/routes/account.js | 29 +- packages/webui/server/routes/model.js | 502 +------ packages/webui/server/routes/protocol.js | 49 +- .../test/lib/engine/account-reads.test.js | 449 +++++++ .../test/lib/engine/capability-reads.test.js | 477 +++++++ .../webui/test/lib/engine/model-reads.test.js | 1181 +++++++++++++++++ release/public-source.json | 6 + scripts/test-tmp-leak.check.mjs | 1 + 17 files changed, 3767 insertions(+), 482 deletions(-) create mode 100644 packages/webui/server/engine/account-reads.js create mode 100644 packages/webui/server/engine/capability-reads.js create mode 100644 packages/webui/server/engine/model-reads.js create mode 100644 packages/webui/test/lib/engine/account-reads.test.js create mode 100644 packages/webui/test/lib/engine/capability-reads.test.js create mode 100644 packages/webui/test/lib/engine/model-reads.test.js diff --git a/packages/webui/docs/API.md b/packages/webui/docs/API.md index 4ddb7595..7effdb52 100644 --- a/packages/webui/docs/API.md +++ b/packages/webui/docs/API.md @@ -2416,10 +2416,23 @@ insensitive, trailing slash-insensitive, `\` and `/` interchangeable). ### `GET /api/protocol/capabilities` -Returns the engine's `agentInfo` (from the `initialize` reply) plus the +Returns the engine's `agentInfo` (from the `initialize` reply), the capability table webui knows about (`MCODE_ACP_CAPABILITIES` in -`server/lib/mcode-rpc.js`).

Its +// primary sources are files webui owns and can read without the engine: +// `models.json` / `~/.mcode-webui/providers.json` on the webui side, and +// a cli-bundle extraction on the engine side. A provider that declared +// no model surface would still leave a fully working picker over the +// webui layers plus the builtins. Gating the endpoint hard would REMOVE +// working functionality in response to a declaration about a capability +// the endpoint does not actually depend on — the exact reasoning +// `session-export.js` records for #11, reused here rather than +// re-argued. So `checkModelReadCapability` REPORTS and never throws; the +// read is unaffected by what it reports, and the report is what a later +// batch needs in order to decide whether the engine LAYER may be trusted. +// +// What this file deliberately does NOT do: +// +// - It does not re-implement the engine's own projections. +// `lib/engine-catalogue.js` owns the thinking schema, the +// context-window hygiene rules, the wire-form parser, the +// `custom_provider` read and the layer merge. A second projection +// here would be a second answer to a question with exactly one. +// - It does not write. `handleSetModel` stays in the route for B7/B9; +// this batch only moves the READ. +// - It does not build a second provider host and does not call any +// provider method: every source here is a file read, which is why +// the sub-item below names a READ rather than a method webui calls. +// +// Boot-path weight — the ONE place this batch deviates from the +// sibling families, and the deviation is deliberate on both sides of +// the import. +// +// The four static imports below (`lib/config.js`, +// `lib/engine-catalogue.js`, `lib/models.js`, `lib/providers-config.js`) +// were ALREADY static imports of `routes/model.js` before M3-B4, so the +// server's boot cost is exactly what it was. What they must not do is +// reach `@mavis/*` or `js-yaml` through the SHARED facade — and they +// do reach `@mavis/shared/local-runtime-paths` (via `lib/config.js`) +// and `js-yaml` (via `engine-provider-sync.js`). That is why this module +// is deliberately NOT re-exported from `engine/index.js`, and why +// `routes/model.js` imports it directly: `test/lib/engine/host-facade.test.js` +// guards `engine/index.js` and `routes/plugins.js` against exactly that +// pull, and the guard is right. See `engine/index.js` for the full +// statement and for what has to be true before this can move back. +// +// The price is that the read is SYNCHRONOUS. Making the four imports +// dynamic would let the module re-export from the facade, at the cost of +// turning `handleGetModels` into an async handler — a contract change +// for any caller that does not await, and the exact thing this batch +// promises not to do.

So the four things pinned here are: +// +// 1. THE FULL SNAPSHOT (section 5). One rich fixture — engine session +// option, engine `custom_provider` layer, webui config layer, +// builtin layer, a builtin that COLLIDES with a config entry, a +// switchable variant model, an effort-list model, a forced_on +// model, two providers with overlapping upstream model ids, a +// provider with a key and one without — projected to the exact +// response body the pre-refactor route produced. The expected +// value below was captured from the implementation at 3362c9be +// (B3's rebase tip) and pasted in longhand: it is NOT recomputed +// by the functions under test, because a snapshot whose oracle is +// the implementation proves nothing. The two `minimax_api` models +// that are ABSENT from the builtin half of the `minimax_api` +// group are the load-bearing part: the config layer took those +// slots wholesale, which is ticket 09-02's dedupe rule. +// +// 2. THE PURE PROJECTIONS ON THEIR INPUTS (sections 3–4). Each rule +// the snapshot exercises incidentally is also asserted on a +// minimal input of its own, so a failure names the RULE that broke +// rather than pointing at a 280-line diff. +// +// 3. THE VARIANT / CONTEXT PERTURBATION (section 6). The thinking +// levels and the context-window options are two projections of one +// engine file, and the interesting failure is a cross-wiring: an +// annotation attached to the wrong entry, or the builtin tree read +// twice so the two sites disagree. The test perturbs one engine +// model at a time and records exactly which entries move. +// +// 4. THE GATE IS SOFT, AND THE MOCK IS REAL. The registered provider +// declares `authCredentials` `full`, so only this file can prove +// the soft gate reports what it claims; and node:test's +// `mock.module` re-evaluates only the MOCKED specifier, so every +// route test re-imports the route under a fresh `?bust=N`, and +// section 7 ends with the control that proves the mock took. +// +// Fixture ordering is load-bearing, not stylistic. `lib/config.js` +// resolves `MCODE_WEBUI_DATA_DIR` / `MINIMAX_DATA_DIR` at MODULE LOAD, +// and `engine/model-reads.js` imports it statically — so the fixture +// directories and the env are built at module top level, BEFORE the +// first import that reaches a server module.

charset=UTF-8 Content-Transfer-Encoding: 8bit `GET /api/protocol/capabilities` used to answer from two hand-maintained places: `MCODE_ACP_CAPABILITIES`, a flat `{method: boolean}` table of the ACP JSON-RPC surface, and the `initialize` agentInfo mirror. The engine's DECLARED capability surface already existed — the 14-key per-provider object that `GET /api/engine-capabilities` serves — so webui was carrying two parallel answers to "what can this engine do", able to disagree, with no test able to notice. This makes `capabilities` the declared object and drops the wire table from the endpoint. This is a reviewed, user-authorised endpoint contract change, not a refactor side effect, and it is stated as such in the module header, in `docs/API.md` and in both ARCHITECTURE twins. The twelve old accessors are asserted GONE, so a consumer reading `capabilities.set_mode` gets undefined and fails loudly rather than receiving a truthy object field. No runtime consumer exists: nothing in `webapp/` reads this endpoint, and `engine/capability-reads.js` no longer imports `lib/mcode-rpc.js` at all (pinned by a static tripwire, because an unused import is behaviourally inert and no behavioural test could see it). The `engine` key the previous commit added is REMOVED rather than kept: with `capabilities` already the declaration, an `engine` block would carry the same 14 keys a second time in one response. What survives from that shape is the provenance — `capabilitiesProvider` / `capabilitiesProviderFor`, the honest bit that says whether the declaration came from the active transport's provider or from the default one standing in — plus `capabilitiesUnavailable` for the derived degradation roll-up. A test counts the declaration's occurrences in the serialised body and requires exactly one, so a second carrier is a red bar. `MCODE_ACP_CAPABILITIES` is kept and stays pinned by `test/lib/mcode-rpc.check.mjs`: it is still a true statement about the ENGINE's ACP surface and `docs/CAPABILITIES.md` cites it as one. It has no webui consumer left, recorded as debt in the module header rather than deleted as a side effect. `docs/webui.md` and `docs/webui.zh-CN.md` gain a diff here for the first time in this migration: they carried the old response shape in their endpoint tables, and an authorised contract change has to be documented where the contract is written. --- docs/tui-capabilities.md | 16 +- docs/webui.md | 2 +- docs/webui.zh-CN.md | 2 +- packages/webui/docs/API.md | 112 ++++---- packages/webui/docs/API.zh-CN.md | 107 ++++---- packages/webui/docs/ARCHITECTURE.md | 35 ++- packages/webui/docs/ARCHITECTURE.zh-CN.md | 26 +- .../webui/server/engine/capability-reads.js | 96 ++++--- packages/webui/server/routes/protocol.js | 37 ++- .../test/lib/engine/capability-reads.test.js | 242 ++++++++++++------ packages/webui/test/lib/mcode-rpc.check.mjs | 14 +- 11 files changed, 431 insertions(+), 258 deletions(-) diff --git a/docs/tui-capabilities.md b/docs/tui-capabilities.md index 4b53b058..df506203 100644 --- a/docs/tui-capabilities.md +++ b/docs/tui-capabilities.md @@ -220,7 +220,11 @@ Status legend: ✅ wired · ⚠ partial / path differs · ❌ no path · 🚧 re The webui does not yet expose `/fork`, `/resume`, or a "rewind last turn" action — those acp methods (`fork`, `resume`) are reported by -`MCODE_ACP_CAPABILITIES` but no webui route wraps them. +`MCODE_ACP_CAPABILITIES` but no webui route wraps them.

No logic changes; both were documentation lying about the code next to it. `engine/index.js` still described #73 as an additive change — "the response body gains a key (`engine`, the engine-capabilities view) … additive rather than a replacement". The second B4 commit made it a REPLACEMENT and deleted the `engine` key, so the facade's own export table was the one place still telling a reader the opposite of what the endpoint does. It now states the replacement, why the `engine` key was removed rather than kept, and what survived from it (the provenance keys and the derived roll-up). `docs/ARCHITECTURE.md` and its zh-CN twin called `engine/account-reads.js`'s read **synchronous**. It is `async` — `readEngineAccount` awaits a `Promise.all` of dynamic imports — and the boot-path note the row pointed at describes model-reads, not this module. The same two documents already listed account-reads correctly under the `await import()` rule a few paragraphs down, so the file contradicted itself in two languages at once. Both rows now say asynchronous and point at the ordinary rule. Also drops a dead `assertEngineCapability` import from `engine/model-reads.js`: the soft gate inspects the declaration inline, so the throwing helper was never called and its presence read as if the soft path could still throw. Replaced by a comment saying why it is absent, so the next reader does not "fix" it back in. And the one comment with Chinese embedded mid-sentence (仓库 review 要求注释用英文) is now English; the header parentheticals naming each family (账户读 / 模型目录读 / 能力声明读) stay, as do the quoted product strings — `本地用户` is the real zh-CN value of `userMenu.localUser` and `shell.tsx` cites it the same way. --- packages/webui/docs/ARCHITECTURE.md | 2 +- packages/webui/docs/ARCHITECTURE.zh-CN.md | 2 +- packages/webui/server/engine/index.js | 14 +++++++++++--- packages/webui/server/engine/model-reads.js | 9 +++++++-- 4 files changed, 20 insertions(+), 7 deletions(-) diff --git a/packages/webui/docs/ARCHITECTURE.md b/packages/webui/docs/ARCHITECTURE.md index 09a77dc9..7bbc4c1f 100644 --- a/packages/webui/docs/ARCHITECTURE.md +++ b/packages/webui/docs/ARCHITECTURE.md @@ -505,7 +505,7 @@ files, one job each: | `engine/session-tree-reads.js` | The session-tree family's facade call (`readEngineSessionTree`) and the endpoint→capability table `SESSION_TREE_ENDPOINTS` (step M3, batch B2).

They ask engine/session-writes.js instead, so the load -> resolve -> authorize -> intent-audit -> mutate ordering — and the resurrection guard inside it — becomes named, testable code rather than a two-line helper a route could call out of order. #7 and #6 gate HARD on sessionCrud.deleteSession, because the rows they destroy are the engine's own; #4 declares no capability at all, because a rename writes webui's own store and touches no engine surface. The policy is decided by who owns the rows the write destroys, which is a different question from the read families' and does not have the same answer twice in a row here. The facade exposes a plan/commit pair rather than one deleteSession(), so the write-ahead audit still lands between "know what the user asked to delete" and "delete it". Response bodies are built in the facade once, which is what lets the #6 and #7 dryRun shapes be pinned byte-for-byte by unit tests. No status code, response body or error code changes. The 32-table delete SQL stays in lib/mcode-session-delete.js and is reached by dynamic import; acp-client.js and four test files bind to that specifier, so collecting it is a later batch's job.

Three +// facts about that delete are load-bearing and none of them is visible +// at the call site once the route has grown to 270 lines: +// +// 1. THE RESURRECTION GUARD. The long-lived mcode ACP child holds the +// session in memory and rewrites its registry row on the next +// request, so a delete that only removes SQL rows comes BACK. The +// order is the whole mechanism: kill the child → delete the rows → +// drop ONLY the deleted sid from the cache (not the whole cache — +// invalidating everything flashes the sidebar 42 → 16 → 42 and +// reads to the user like the delete failed). A refactor that +// reorders these three steps reintroduces "deleted session +// reappears" without failing any single assertion. +// 2. CACHE INVALIDATION PRECEDES THE ENGINE WRITE. +// `invalidateSessionTree()` runs before the engine delete so the +// next read cannot repopulate a cache from a database this call is +// about to change. Same reason, same asymmetry. +// 3. THE CROSS-TAB FAN-OUT. Every client whose `sessionId` or +// `mcodeSessionId` pointed at the deleted record has its active +// session cleared and its usage counters zeroed, because the next +// interaction in that tab would otherwise silently recreate a webui +// wrapper for the very `mvs_` sid that was just deleted. The +// orphan branch clears only the REQUESTING client, because an +// orphan mcode session has no wrapper for another tab to be +// "inside". That asymmetry is real and load-bearing; flattening it +// would clear tabs that were never on the deleted session. +// +// So the sequencing lives here, named, and tested on its steps; the route +// keeps what is genuinely its own — HTTP parsing, the `authorize()` +// modal, the write-ahead audit ordering, and every status code. +// +// The one thing this file does NOT do is move the SQL. +// `lib/mcode-session-delete.js` keeps the 32-table `local_runtime_*` +// delete (its own header, its own per-table error classification, its +// own `getDb` seam) and this file reaches it through `await import()`. +// That is the same split B3 and B4 drew for their storage access +// (`lib/mavis-usage.js` owns the usage SQL, `lib/mcode-rpc.js` owns the +// account RPC), and it is the only shape that survives a real +// second reader appearing. The plan for this batch annotated +// `mcode-session-delete.js` "delete"; it is KEPT, and the reason is +// recorded as KNOWN DEBT in the module header of +// `lib/mcode-session-delete.js` itself. `lib/acp-client.js` imports +// `deleteMcodeSessionFromDb` from it, and four test files +// (`mcode-session-delete.test.js`, +// `mcode-session-delete-outcomes.test.js`, `sqlite-resolver-c01.test.js`, +// `sessions-switch.check.mjs`) bind to that exact specifier — deleting +// the module would break a live consumer and silently de-mock two +// existing route suites. KNOWN DEBT means "recorded and still +// uncollected", not "safe to remove". +// +// Boot-path weight. `app.js` imports the routes, the routes import this +// file, so this file is on the boot path. It statically imports nothing +// heavier than `capabilities.js` and `index.js` (both pure declaration +// modules); `lib/sessions.js`, `lib/acp-client.js`, +// `lib/mcode-session-delete.js`, `lib/session-tree.js`, `lib/state-bus.js` +// and `lib/config.js` are all reached through `await import()` inside +// the functions.

The new engine/session-switch.js owns the four load-bearing facts the ~290-line handler had accumulated: the mvs-sid-first resolution order (single base-session identity), the backfill decision and its read, the workspace containment gate (which runs before any cs mutation, so a refused switch leaves the client untouched), and the response body. The gate is SOFT — it reports and never throws — because the switch's primary data is webui's own record and both engine touches have a defined degradation. Gating hard would remove a working endpoint over a title and a transcript, and would do it on the default acp transport first. The route keeps what is its own: the "id required" 400, the status mapping, the fail-closed audit and the SSE push — the audit has to land after the switch has already mutated cs, and the push must not fire when it fails. Behaviour is unchanged and pinned: the four red lines (transcript backfill, cumulative detection, workspace containment, single base session identity) each get named tests with their negative half, and the success body's key ORDER is compared as a string. Six mutations of the facade were run to prove the tests are load-bearing. KNOWN DEBT 1 in the new module records what this batch did NOT retire: the 3-candidate transcript probe. The default acp transport has no engine surface to replace it with, getMessages paginates where the probe caps lines, their orderings differ, and export's enrichment is still byte-pinned to the same candidates. What IS retired is the coupling — the route no longer names lib/transcript.js, and the probe list is an implementation detail behind one seam. --- packages/webui/server/engine/index.js | 41 +- .../webui/server/engine/session-switch.js | 992 ++++++++++++ packages/webui/server/routes/sessions.js | 514 +----- .../test/lib/engine/session-switch.test.js | 1392 +++++++++++++++++ release/public-source.json | 2 + scripts/test-tmp-leak.check.mjs | 4 + 6 files changed, 2505 insertions(+), 440 deletions(-) create mode 100644 packages/webui/server/engine/session-switch.js create mode 100644 packages/webui/test/lib/engine/session-switch.test.js diff --git a/packages/webui/server/engine/index.js b/packages/webui/server/engine/index.js index d91751c4..589a6ac9 100644 --- a/packages/webui/server/engine/index.js +++ b/packages/webui/server/engine/index.js @@ -36,9 +36,9 @@ // catalogue host itself is now reached through this facade too // (engine/host.js), so the plugins and turn-diff routes no longer name // lib/acp-client.js.

Before M3 all of it lived in the route — resolve, +// overlay creation, title lookup, transcript backfill, workspace +// containment, per-client state mutation, the response body — in one +// ~290-line handler whose middle half (the engine-facing half) reached +// into `lib/acp-client.js` and `lib/transcript.js` directly. Three facts +// about that handler are load-bearing and none of them is visible from +// the route's edge any more: +// +// 1. THE BACKFILL DECISION IS A DATA DECISION, NOT A ROUTE DECISION. +// A stored chat buffer is written when it is empty OR when it looks +// cumulative (a later `●` line is a strict superset of an earlier +// one — the segment-accumulator bug, session-isolation/06). A clean +// stored buffer is kept untouched even though the engine DB is +// DB-authoritative, because transcript-sync overwrites the stored +// chat within ~4s anyway and clobbering a clean buffer on EVERY +// switch is a worse failure than not backfilling. That rule, and +// the predicate that decides it, belong with the reader that backs +// it up — not in a route that would have to know the difference. +// +// 2. THE READ MUST NEVER BREAK THE SWITCH. Every transcript failure +// path — missing db, unloadable better-sqlite3, schema drift, a +// throwing probe — degrades to "keep the stored chat" and the +// switch still answers 200. That is the endpoint's oldest promise +// and it is the reason this family's gate is SOFT (see below): a +// switch that 501s because an enrichment was unavailable has +// turned a degraded read into a dead endpoint. +// +// 3. THE WORKSPACE WRITE IS A CONTAINMENT GATED SIDE EFFECT. The +// target's stored `workspace` is historical input — it may name a +// directory the user has since removed from the allowed roots. The +// switch resolves target-first, NEVER falls back to the workspace +// the user is currently in (that is the reported "file tree still +// shows the previous project" defect), and refuses with a 400 +// rather than writing a path the picker would have rejected. The +// gate is `lib/workspace.js#assertWorkspacePath` — the same one +// `handleWorkspaceChange`, `handleNewSession` and the fs routes use +// — and it runs BEFORE any `cs` mutation, so a refused switch +// leaves the client state exactly as it was. +// +// Why this family's gate is SOFT, when the write family (B5) gates hard +// and the tree family (B2) gates hard. The question behind that choice +// is "if the provider declares this capability absent, can the endpoint +// still serve a truthful answer?" — and for #3 the answer is yes: +// +// - The payload's primary data is webui's OWN store. The record, its +// title, its chat and its workspace all live in `sessions.json`. +// - Both engine touches are enrichments that already have a defined +// degradation: the title falls back to the cache and then to the +// "Mcode session" placeholder, the transcript falls back to the +// stored chat. Neither failure is visible as a failure. +// - Gating hard would REMOVE a working endpoint in response to a +// declaration about a capability it does not depend on, and it would +// do so under exactly the transport where the endpoint has the most +// users. That is B2's `session-export.js` argument, reused rather +// than re-argued: a missing enrichment must not be dressed up as a +// failure (#110 fake-success discipline, applied in the other +// direction). +// +// So `checkSessionSwitchCapability` REPORTS and never throws. The 501 +// machinery in `errors.js` stays unused by this family — a policy +// statement, and the suite pins that it stays unused. +// +// What this file deliberately does NOT do: +// +// - It does not re-implement the transcript. `lib/transcript.js` owns +// the read and `messagesToChatLines` owns the chat-line grammar; this +// file owns the DECISION to read and the decision to keep what came +// back. See KNOWN DEBT 1 for why the 3-candidate probe behind that +// read survives this batch. +// - It does not own the workspace boundary. `assertWorkspacePath` +// stays the single gate every workspace write funnels through. +// - It does not own the session store. `lib/sessions.js` keeps the +// load/save and the overlay rule; this file orders the calls. +// - It does not build a host. There is no host on this path at all. +// +// Boot-path weight. `app.js` imports the routes, the routes import this +// file, so this file is on the boot path. It statically imports nothing +// heavier than `engine/capabilities.js` and `engine/index.js` (both pure +// declaration modules) and nothing else; `lib/sessions.js`, +// `lib/acp-client.js`, `lib/transcript.js`, `lib/mavis-usage.js`, +// `lib/models.js`, `lib/workspace.js`, `lib/state-bus.js` and +// `lib/config.js` are all reached through `await import()` inside the +// data-plane function.

THE 3-CANDIDATE TRANSCRIPT PROBE IS STILL HERE, and this batch is +// the batch the plan named for retiring it (plan §7: "transcript DB +// 探针 … → getMessages"). It could not be retired without breaking +// this batch's own red line, and the reason is not a matter of taste: +// +// a. THE DEFAULT TRANSPORT HAS NO ENGINE SURFACE. The `acp` +// transport is the default and NO provider is registered for +// it — `providerByTransport()` returns `{runtime: …}` only, +// precisely so this gate reports +// `gate: "unregistered-transport"` and the pre-M3 behaviour +// survives. `cliService.getMessages` is reachable only through +// the v2 catalogue host, which only the `runtime` transport +// boots. Deleting the probe therefore empties the backfill on +// the default transport and on half of the two-transport test +// matrix this batch is gated on. That is red line 1 +// (转录回填) failing, not a refactor completing. +// b. THE TWO READS CAP DIFFERENT THINGS. The probe reads a whole +// session and caps the mapped LINES at 400 / 200KB +// (`messagesToChatLines`). `getMessages` paginates — +// `limit`, `before`, `nextCursor`, `hasMore` — so it caps +// MESSAGES. The two are interchangeable only after proving +// that the tail of a bounded message page yields the same +// 400 lines, which needs a live v2 host to measure. +// c. THE ORDERING IS NOT THE SAME ORDERING. The probe orders +// `created_at_ms ASC, rowid ASC`; `getMessages` orders by +// `MessageQueryService`'s own key. On ties the two disagree, +// and a transcript whose order flips is a transcript the user +// reads wrong. +// d. EXPORT STILL OWNS THE LEGACY CANDIDATES. B2 left +// `GET /api/sessions/:id/export` on the legacy-only probe set +// on purpose — its `mcode_unavailable` shape is byte-pinned by +// existing tests against exactly those three candidates, and +// widening export's set would change its enrichment from +// "unavailable" to "answering", which is a product change, not +// a migration step. +// +// What this batch DID collect is the coupling that made the probe +// look unremovable: `routes/sessions.js` no longer names +// `lib/transcript.js` at all, the read has one seam +// (`readEngineSwitchTranscript`), and the 3-candidate list plus the +// v2 data_json probe are now an implementation detail of the engine +// layer rather than something two routes import directly. The +// remaining work is a SEAM SWAP, not a redesign, and it belongs to +// M4-1 — the batch that registers an ACP provider and therefore +// makes an engine surface reachable under the default transport. +// It should land together with an equivalence test against a live v2 +// host, and with export's probe set widened in the same commit so +// the two endpoints cannot drift apart again. +// +// 2. THE FIRST-TOUCH OVERLAY IS STILL A WEBUI-SIDE WRITE. A bare +// `mvs_…` switch creates a record in `sessions.json` that the +// engine knows nothing about, and the engine's own session list and +// webui's wrapper list are two different questions that happen to +// agree. This is pre-existing behaviour (the alternative — +// registering the session engine-side — is a product decision about +// who owns session identity), and this batch did not change it. +// +// 3. THE USAGE SYNC IS NOT GATED. `applyMavisUsageToCs` reads webui's +// own mavis tables, so it declares no capability, and its failure +// is still swallowed with a debug-only warning. That asymmetry — +// identity and transcript are degraded, usage is dropped silently — +// predates this batch. Naming `usageStats` here would gate a working +// endpoint on a capability whose absence changes nothing visible; +// the real question is whether a silent drop is the right product +// behaviour at all, and that is not this batch's to decide. diff --git a/packages/webui/server/routes/sessions.js b/packages/webui/server/routes/sessions.js index f5441611..3da48c3a 100644 --- a/packages/webui/server/routes/sessions.js +++ b/packages/webui/server/routes/sessions.js @@ -4,42 +4,34 @@ // GET /api/acp-sessions, GET /api/acp-session-title, // GET /api/sessions/search (Lease C05 — cross-workspace fuzzy match) // (v0.5.bx-33: 删 POST /api/sessions/cleanup-orphans — Wzdhehe 不要这个 UI,API 一起删) +// +// What is left in this file after M3 is the HTTP surface of the session +// endpoints: parse the request, pick the status code, run the fail-closed +// audit, push the SSE frame, answer.

The facade returns outcomes (`ok`, +// `not_found`, `workspace_refused`) and never learns what a status +// is; `statusHint` carries the number so the mapping is one table +// here instead of three branches inside the engine layer. +// - THE AUDIT, fail-closed. `_eventsAppend` THROWS on write failure +// and a governance action must not complete with a missing audit +// trail, so the append sits between the facade's work and the +// response, and its failure answers 500 through `_auditFail`. +// - The state push and the two log lines that bracket the response. +// +// The ordering constraint the facade could not own is the reason the +// audit stays put: the switch has ALREADY mutated `cs` by the time this +// append runs (that is pre-existing behaviour — a failed audit leaves +// the client switched and reports 500, which is what the operator sees +// today), and the SSE push must not fire when that append failed.

It is true exactly when a child was registered AND the +// gentle path did not take (`child && !cancelled`) — i.e. webui +// called `child.kill()` on its way out of the handler. It is written +// into the response body BEFORE the bounded escalation timer can +// possibly fire, so `hardKilled:true` never certifies that anything +// is dead. The same asymmetry is why the `note` string says "hard +// kill (session/cancel could not be delivered)" even when NO kill +// ran at all (no child, no session id): the note names why the +// gentle path did not happen, not what followed. Both are load- +// bearing wording, and both are pinned. +// +// 3. THE ESCALATION IS BOUNDED, AND THE BOUND IS PART OF THE +// CONTRACT. If the gentle cancel does not take, a `setTimeout` at +// `STOP_FORCE_KILL_MS` re-checks the CACHED raw child handle and +// kills it if it is still alive. Two properties are load-bearing +// and both are pinned: the timer is `unref()`ed (an unexpired stop +// timer must never hold the process open), and it reads the handle +// captured BEFORE the timer was armed — `child.child` may be nulled +// by the runner's own stop() in the meantime, and a nulled handle +// read at fire time would silently skip the escalation the whole +// cascade exists for. +// +// Why this family's gate is SOFT. The question B5 and B6 each answered +// for their own family was "if the provider declares this capability +// absent, can the endpoint still serve a truthful answer?" — and here +// the answer differs by endpoint, which is the honest answer: +// +// - #13's escalation is webui's OWN child-process management. The +// child was registered on webui's state bus by webui's own runner; +// killing it does not consult a provider, and neither does the +// zombie-claim reset (the 2026-09-20 audit escape hatch, which +// exists precisely for the case where the runner died before its +// own finalize ran). Hard-gating #13 would DELETE the user's only +// way out of a stuck 思考中 panel, in order to express a doubt +// about the GENTLE half of a two-mechanism endpoint. That is the +// `session-export.js` argument again: a missing enrichment must not +// be dressed up as a failure. +// - #69 already HAS a truthful "I could not do it" answer, and it is +// its documented contract: 200 `{ok:true, cancelled:false, warning, +// code, killEndpoint}`. A provider with no interrupt surface produces +// exactly that shape (the notification is inapplicable, which is +// what "no client" already means), so a hard gate would replace an +// accurate 200 with a 501 and teach the frontend a shape it does not +// have today. +// +// So `checkInterruptCapability` REPORTS and never throws, and the 501 +// machinery in `errors.js` stays unused by this family — a policy +// statement, and the suite pins that it stays unused. +// +// What this file deliberately does NOT do: +// +// - It does not own the client-state reset. `resetThinkingClaim` is +// shared with `routes/chat.js#handleSend` (the start-phase failure +// path), so it stays in the route; the DECISION to run it +// (`claimStale`) is computed here and the mutation stays put. +// - It does not own the process-kill policy beyond the bounded timer +// and its two guards.

Three facts about that work are load-bearing and none of +// them is visible from the route's edge any more: +// +// 1. #70's SIDEBAR ENTRY IS DOWNSTREAM OF THE ENGINE'S ANSWER, NEVER A +// PEER OF IT. `createWebuiEntry` adds a record to `sessions.json` +// so the sidebar can show a session the TUI started — but it may +// only be created once the engine has confirmed the load. A +// provider that cannot load must not be able to leave a sidebar +// entry pointing at a session the engine never opened, and a +// failed load must not leave one either. This is the invariant that +// decides #70's gate (see below), and it is why the entry creation +// is ordered strictly after the capability check and the engine +// call rather than being a parallel "best effort" branch. +// +// 2. THE ENTRY IS IDEMPOTENT, AND IDEMPOTENCE IS ABOUT THE +// `mcodeSessionId` MATCH, NOT THE CALLER. A second +// `createWebuiEntry` for a session webui already wraps returns the +// EXISTING record without re-saving, so repeated calls cannot grow +// duplicate sidebar entries for one conversation. This is +// pre-existing behaviour and the suite pins both halves (first +// call creates, second call returns the same id and does not grow +// the store). +// +// 3. #71's ORDER IS `mcodeSessionId` FIRST, `resetContext` SECOND. +// `resetContext` re-roots the context panel from the client state, +// so it has to observe the NEW session id — reversing the two +// leaves the panel describing the session the user just left. The +// pair is also the endpoint's entire meaning, which is why the +// response is built here next to it and never re-assembled. +// +// Why this family's gate is SPLIT, and why the split is not a +// compromise between two opinions. +// +// Both endpoints declare the same capability — `sessionCrud`, the same +// key B1 uses for the title read and B5 uses for the delete — but they +// need different answers to "if the provider declares this absent, can +// the endpoint still serve a truthful answer?", and the two answers are +// not close: +// +// - #70 GATES HARD. Its only purpose is to make the engine load a +// session; there is no webui-side fallback, and by fact 1 a +// "success" that skipped the engine would write a sidebar entry +// for a session that does not exist on the engine side. That is the +// fake-success failure mode #110 exists to prevent, in the exact +// shape the gate exists to prevent: a 200 with an entry and no +// session. The 501 machinery in `errors.js` is therefore in use by +// this endpoint, and the router's existing central mapping answers +// it — no route has to remember to catch it. +// +// - #71 GATES SOFT, and the reason is that hard-gating it would BE +// the decision a human has not made yet. The plan (§3a, the +// activate row) records the situation exactly: one ACP client +// tracks a single active session, so "activate another" is how the +// client is re-pointed; the in-process host has NO single-active- +// session concept at all; and the endpoint's fate is therefore an +// either/or — "语义塌缩（cs 切换 + resume）, 或 501". Those are two +// different products. Choosing the 501 branch is a real answer to +// that question and this batch is not entitled to give it: it would +// be given silently, by a capability table, with no changelog and +// no frontend work. So `checkSessionActivateCapability` REPORTS, +// the route keeps the pre-M3 shape and status mapping byte for +// byte, and the decision itself is KNOWN DEBT 1 with both branches +// costed. +// +// One family, two gate functions, rather than two modules. B2 split +// `session-tree-reads.js` from `session-export.js` because those two +// endpoints declare DIFFERENT capabilities and their gate MECHANICS +// differ (throw vs report) for unrelated reasons. Here the mechanics +// are the same two functions every other family already uses, both +// endpoints share one capability, and they share a store, a client +// state and a route module. Splitting would duplicate the transport +// table, the resolver and the two status mappers to keep a distinction +// that is one `enforcement` field wide — which is exactly the shape +// B5's mixed `session-writes.js` table already carries, for the same +// reason. +// +// What this file deliberately does NOT do: +// +// - It does not decide what #71 means under a provider without +// single-active-session semantics. See KNOWN DEBT 1. +// - It does not own the session store. `lib/sessions.js` keeps the +// load/save and the overlay rule; this file orders the calls. +// - It does not own the status codes.

The situation, from the plan (§3a): one +// ACP client tracks a single active session, so `session/activate` +// is how the client is re-pointed at another one; the in-process +// host has no single-active-session concept at all; and the plan +// gives the endpoint's fate as an either/or — "语义塌缩（cs 切换 + +// resume）, 或 501". Both branches, with what each costs: +// +// a. COLLAPSE INTO "switch + resume". #70 already loads an +// arbitrary session onto the engine, and B6's #3 already +// rebinds webui's client state onto an arbitrary session. So +// the collapsed endpoint is very nearly the COMPOSITION of the +// two endpoints this batch already has behind the facade. The +// cost is not the implementation, it is the RESPONSE SHAPE: +// today's body is `{ok, activeSessionId, data}` where `data` is +// the engine's raw `session/activate` reply, and a collapsed +// endpoint has no such reply to forward. It would have to grow +// the switch payload (B6's `{ok, session:{…}}`, a much larger +// and byte-pinned object) or invent a new one — and either way +// the frontend, the docs and the two-language documentation all +// change. It also changes the endpoint's MEANING: "activate" +// today mutates nothing in webui's state beyond the two lines +// in step 4, while "switch" re-roots the workspace, the chat +// buffer and the context counters. A frontend that keeps +// calling it as activate would suddenly get a workspace change. +// b. 501 WHEN NO PROVIDER CAN ACTIVATE. Cheap to build — the +// hard-gate machinery already exists in this very file for +// #70, and the router already maps the error. The costs are +// elsewhere: it is a user-visible behaviour change on a route +// the frontend calls today, it needs the §4.2 UI degradation +// (hide or disable the entry point, not an error toast), and +// it would fire for EVERY provider that has no single-active- +// session concept — which, per the plan, is the in-process host +// the default runtime transport is built on. In other words the +// 501 branch most likely lands on the transport with the most +// users, for an endpoint that works today. +// The tie-breaker is product knowledge this batch does not have: +// who calls #71, and what they expect to happen to the sidebar, +// the chat buffer and the workspace when it returns 200. That is +// the question to ask; the answer decides the branch. Until then +// the endpoint keeps its pre-M3 shape and status mapping, and +// `checkSessionActivateCapability` keeps reporting. +// +// 2. #70's SIDEBAR ENTRY IS STILL A WEBUI-SIDE WRITE THE ENGINE +// KNOWS NOTHING ABOUT. The same asymmetry B6 recorded for the +// switch's first-touch overlay: webui's wrapper list and the +// engine's own session list are two different questions that +// happen to agree. Pre-existing behaviour, unchanged here, and +// closing it means deciding who owns session identity. +// +// 3. #70's 501 IS THE GATE'S 501, NOT THE ROUTE'S. `loadSession` +// answers 500 for `code === "unsupported"`, while a provider that +// declares `sessionCrud.loadSession` absent answers 501 with +// `engineCapabilityHttpResponse`'s body. Two different 501s and +// two different bodies can therefore reach this one route, and +// only the second has ever existed. The router's central mapping +// is what keeps them from being confused for each other, and a +// frontend that special-cases the 501 will see the engine-gate +// body first and the RPC-`unsupported` 500 never. Worth +// confirming against the frontend before M4 registers a provider +// that can trip it. +// +// 4. #70's "Resource not found" REWRITE ONLY MATCHES THE STRING FORM. +// The route comment names both shapes the engine can answer with — +// `-32004` and `resource_not_found` — but the rewrite regex +// (`/not.found|resource/i`) only matches the second, so a numeric +// JSON-RPC code reaches the frontend verbatim behind a 500. +// `lib/mcode-rpc.js` puts `e.data.code` into `code`, and that is +// the string form in practice, which is why the gap has never been +// observed. Both behaviours are pinned as-is: widening the regex +// would change a wire shape, and the wider question — whether a +// JSON-RPC numeric code should be translated here at all, or +// normalised once in `mcode-rpc.js` for every caller — is a change +// to the RPC wrapper's contract, not to this endpoint. diff --git a/packages/webui/server/routes/chat.js b/packages/webui/server/routes/chat.js index be02e28b..23e9d857 100644 --- a/packages/webui/server/routes/chat.js +++ b/packages/webui/server/routes/chat.js @@ -14,7 +14,6 @@ import { import { pushStateFor, pushAlert, - getActiveChild, beginRun, endRun, moveRunSession, @@ -37,7 +36,18 @@ import { } from "../lib/interaction/command-registry.js"; import { runMcodeAcp } from "../lib/mcode-acp.js"; import { collectExecResult, runMcodeExec } from "../lib/mcode-exec.js"; -import { cancelSession } from "../lib/mcode-rpc.js"; +// M3-B7 (engine facade): #13 `/api/stop` no longer reaches into +// `lib/mcode-rpc.js#cancelSession` and `lib/state-bus.js#getActiveChild` +// from inside the handler.

So `checkSessionSwitchCapability` +reports and never throws; the 501 machinery in `engine/errors.js` stays unused +by this family, and the suite pins that it stays unused. That is the +`engine/session-export.js` argument reused rather than re-argued — the #110 +fake-success discipline applied in the other direction, since a missing +enrichment must not be dressed up as a failure. + +**The backfill decision is a data decision, not a route decision.** +`engine/session-switch.js#selectTranscriptBackfill` is the whole rule, +and it has exactly three branches, each of which the operator log +distinguishes by name: + +| `reason` | Stored buffer | Action | +| --- | --- | --- | +| `empty` | no chat yet | read the engine transcript and re-persist — unchanged since the first version of this path, because a session that was never rendered must show its history rather than "No messages yet" | +| `stored_cumulative` | polluted by the segment-accumulator bug | prefer the engine read and re-persist.

It is +O(n²) in the `●` line count, and that is affordable because a session's +`chat` is capped at ~400 lines. It is conservative on both sides: a +single-`●` buffer is never cumulative, non-`●` rows (system, tool, `▲` +thought) are ignored, and equal-length lines are a tie rather than a +superset. The third branch deliberately does **not** promise draft +preservation — the composer keeps its own draft in its own state. + +**The read must never break the switch.** +`engine/session-switch.js#readEngineSwitchTranscript` never throws. +Every failure path — missing db, unloadable `better-sqlite3`, schema +drift, a throwing probe — lands as `{ok: false, reason}` and the caller +keeps the stored chat, so a switch that 501s because an enrichment was +unavailable never becomes a dead endpoint. The `reason` strings are the +reader's own, forwarded verbatim, because the operator log that reports +them and the reader's own vocabulary are one contract. + +**The workspace write is a containment-gated side effect, and it runs +before any `cs` mutation.** The target's stored `workspace` is +historical input: it may name a directory the user has since removed +from the allowed roots. `engine/session-switch.js#resolveSwitchWorkspace` +resolves target-first and passes the candidate through the same +`workspace.js#assertWorkspacePath` that the workspace picker, +`handleNewSession` and the fs routes use. Two properties are +load-bearing. The switch **never** falls back to the workspace the user +is currently in — that is the reported "file tree still shows the +previous project" defect, and it is why `currentWs` is not a parameter +of that function. And a refused switch answers 400 +(`workspace_refused`, a third outcome next to `ok` and `not_found` +rather than an exception) with the client state left exactly as it was. +A new first-touch overlay is created with `workspace: ""`, so +target-first resolution lands on `DEFAULT_WORKSPACE` for it instead of +stamping it with whatever project the switch happened to start from. + +**Resolution order is `mvs_` first, and that is the single-base-session +rule.** `engine/session-switch.js#resolveSwitchTarget` matches the +engine session id before the webui uuid — the **opposite** of the write +family's `resolveSessionTarget`, and the difference is a product rule +rather than a style choice. A switch addressed by `mvs_` must land on +the record that *is* that engine session, because the endpoint's whole +point is one conversation with one identity; the delete and rename paths +are addressed by a user who already has the record in front of them and +look the uuid up first. A first-touch `mvs_` therefore creates exactly +one overlay record whose id **is** the `mvs_` sid, via +`sessions.js#ensureOverlayForMcodeSid`, and `matchKind` stays `null` so +the audit payload's `matchKind || "new_from_mcode"` fallback still +labels what operators read as an invented wrapper. The client-state +write (`cs.sessionId`, `cs.mcodeSessionId`, title, chat buffer, the +three cumulative usage counters, and a re-rooted `cs.workspace`) lives +next to `state-bus.js#runChatViewChat`, which is what puts the mid-run +mirror into the response payload. + +**`lastUsedWorkspace` is deliberately left alone.** Last-used is +written only by the send path, because switching is browsing. Pinning +the browsed workspace to the top of the sidebar is the reported "click +any session in C and C auto-sorts first" behaviour, and this batch keeps +it true rather than tidying it up. + +**Three things this batch records as known debt instead of deciding:** + +1. The **3-candidate transcript probe** is still here, and this batch is + the batch the plan named for retiring it. It could not be retired + here without breaking the batch's own red line, for four reasons: + (a) the default `acp` transport has **no engine surface** — + `cliService.getMessages` is reachable only through the v2 catalogue + host, which only the `runtime` transport boots, so deleting the + probe empties the backfill on the default transport and on half of + the two-transport test matrix; (b) the two reads **cap different + things** — the probe reads a whole session and caps the mapped + *lines* at 400 / 200KB, while `getMessages` paginates and caps + *messages*, and the two are interchangeable only after proving that a + bounded message page's tail yields the same 400 lines; (c) the + **ordering is not the same ordering** — the probe orders + `created_at_ms ASC, rowid ASC` and `getMessages` orders by + `MessageQueryService`'s own key, so ties disagree, and a transcript + whose order flips is a transcript the user reads wrong; and (d) + **export still owns the legacy candidates** — B2 left + `GET /api/sessions/:id/export` on the legacy-only probe set on + purpose, because its `mcode_unavailable` shape is byte-pinned by + existing tests against exactly those three candidates, and widening + export's set would turn its enrichment from "unavailable" into + "answering", which is a product change rather than a migration step. + What this batch *did* collect is the coupling that made the probe + look unremovable: `routes/sessions.js` no longer names + `transcript.js` at all, the read has one seam, and the candidate list + is now an engine-layer implementation detail instead of something two + routes import. The remaining work is a seam swap that belongs to + **M4-1** — the batch that registers an ACP provider and therefore + makes an engine surface reachable under the default transport — and + it should land together with an equivalence test against a live v2 + host and with export's probe set widened in the same commit. +2. The **first-touch overlay is still a webui-side write**. A bare + `mvs_` switch creates a record in `sessions.json` that the engine + knows nothing about, so the engine's session list and webui's wrapper + list are two different questions that happen to agree. Pre-existing, + unchanged here; closing it means deciding who owns session identity. +3. The **usage sync is not gated**. `applyMavisUsageToCs` reads webui's + own mavis tables, so it declares no capability and its failure is + still swallowed with a debug-only warning. That asymmetry — identity + and transcript are degraded, usage is dropped silently — predates + this batch. Naming `usageStats` would gate a working endpoint on a + capability whose absence changes nothing visible; the real question + is whether a silent drop is the right product behaviour, and that is + not this batch's to decide. + +#### Which endpoints route through the facade (step M3, batch B7) + +Batch B7 contributes four endpoints across two modules, and the four +have **two** gate policies between them — which is the first batch whose +answer to the gate question is not uniform within its own family. The +split is a fact about the endpoints, not a compromise between opinions. + +| Endpoint | Facade function | Capability · sub-item | Enforcement | Value source | +| --- | --- | --- | --- | --- | +| `POST /api/stop` (#13) | `engine/interrupt.js#applyEngineStop` | `interrupt` · `abortSession` | soft — reports | `mcode-rpc.js#cancelSession` (a notification) plus `state-bus.js#getActiveChild` and the child-process kill — webui's own process management, which consults no provider | +| `POST /api/protocol/cancel` (#69) | `engine/interrupt.js#sendEngineSessionCancel` | `interrupt` · `abortSession` | soft — reports | the same notification alone; the refusal shape is the endpoint's own truthful "I could not deliver it" answer | +| `POST /api/protocol/load-session` (#70) | `engine/session-load.js#loadEngineSession` | `sessionCrud` · `loadSession` | **hard — 501** | `mcode-rpc.js#loadSession`; the sidebar entry is a webui-side write that is only allowed *after* the engine answers | +| `POST /api/protocol/activate-session` (#71) | `engine/session-load.js#activateEngineSession` | `sessionCrud` · `activateSession` | soft — reports | `mcode-rpc.js#activateSession`, then the client-state rebind | + +**`cancelled` does not mean "the prompt stopped".** `session/cancel` is +a **notification**: the engine registers it with `app.onNotification` +and aborts the active prompt's `AbortController`, so a request would +come back "Method not found". A notification carries no reply, which +means a success here means "sent" — the response field is `cancelled` +for historical reasons. #13 and #69 answer that differently on purpose +and both differences are pinned by the suite: #13 pairs `cancelled:true` +with `hardKilled:false` and never escalates, while #69 pairs a refusal +with a pointer to the endpoint that can. + +**`hardKilled` is a report about the first decision, not about the +process.** It is true exactly when a child was registered **and** the +gentle path did not take (`child && !cancelled`) — i.e. webui called +`child.kill()` on its way out of the handler. It is written into the +response body before the bounded escalation timer can possibly fire, so +`hardKilled:true` never certifies that anything is dead. The same +asymmetry is why the `note` string says "hard kill (session/cancel +could not be delivered)" even when no kill ran at all: the note names +*why* the gentle path did not happen, not what followed. Both wordings +are load-bearing and both are pinned. + +**The escalation is bounded, and the bound is part of the contract.** +`engine/interrupt.js#STOP_FORCE_KILL_MS` is 5000 ms, and it is exported +because it is a contract value rather than an implementation detail: the +window is what makes "已停止" mean "已停止". The file this batch +migrated ran 2000 ms; the batch plan transcribed the bound as "abort +5s" and the product call (2026-10-03) took the plan's value, accepting +that a stubborn child gets three extra seconds to finalize at the cost +of "already stopped" being a lie for three extra seconds. Two guards on +the timer are load-bearing. It is `unref()`ed, so an unexpired stop +timer can never hold the process open. And it re-checks the **cached** +raw `child_process` handle captured *before* the timer was armed — +`child.child` may be nulled by the runner's own `stop()` in the +meantime, and a nulled handle read at fire time would silently skip the +very escalation the cascade exists for. + +**Two scoping rules make the cascade act on the right turn.** The child +lookup is narrowed to `(cid, cs.mcodeSessionId)` — the **viewed** +session's child, not "any child of this tab", because a tab may run two +conversations at once and stopping must not signal the other turn's +subprocess. And the zombie-claim reset is a *decision* in the engine +layer, not a mutation: `engine/interrupt.js#stopLeftStaleClaim` answers +`claimStale`, and the route performs `resetThinkingClaim` only when it +is true, because that helper is shared with `handleSend` and moving it +would have been a second, unrelated change to the send route. + +**Why the interrupt family gates soft.** #13's escalation is webui's own +child-process management — the child was registered on webui's state bus +by webui's own runner, and killing it consults no provider. Hard-gating +#13 would delete the user's only way out of a stuck 思考中 panel in +order to express a doubt about the *gentle half* of a two-mechanism +endpoint. #69 already has a truthful "I could not do it" answer, and it +is its documented contract: 200 +`{ok:true, cancelled:false, warning, code, killEndpoint}`; a provider +with no interrupt surface produces exactly that shape, so a hard gate +would replace an accurate 200 with a 501 and teach the frontend a shape +it does not have today. + +**#70 is the only hard gate in this batch, and the invariant behind it +is an ordering.** The sidebar entry `createWebuiEntry` adds to +`sessions.json` must be **downstream of the engine's answer, never a peer +of it**. A provider that cannot load must not be able to leave a sidebar +entry pointing at a session the engine never opened, and a failed load +must not leave one either — a 200 carrying an entry and no session is +precisely the fake-success failure #110 exists to prevent. So +`engine/session-load.js#assertSessionLoadCapability` throws, the 501 +machinery in `engine/errors.js` is genuinely in use for this endpoint, and the +router's existing central mapping answers it — no route has to remember +to catch it. The entry itself is idempotent **on the `mcodeSessionId` +match, not on the caller**: a second call for a session webui already +wraps returns the existing record without re-saving, so repeated calls +cannot grow duplicate sidebar entries for one conversation. + +**#71 gates soft because hard-gating it would *be* the decision a human +has not made yet.** One ACP client tracks a single active session, so +"activate another" is how the client is re-pointed; the in-process host +has no single-active-session concept at all; and the plan gives the +endpoint's fate as an either/or — "语义塌缩（cs 切换 + resume）, 或 +501". Those are two different products, and choosing the 501 branch +here would be choosing it silently, by a capability table, with no +changelog and no frontend work. So `checkSessionActivateCapability` +reports, and the route keeps the pre-M3 shape and status mapping byte +for byte. The endpoint's *meaning* is the order `cs.mcodeSessionId = +sessionId` first and `sessions.js#resetContext` second; reversing the +two leaves the context panel describing the session the user just left. + +**The three status mappings are separate tables, and the differences are +pinned.** `engine/session-load.js#loadFailureStatus` answers 503 for +`no_client`, 404 for a not-found/invalid code and **500** for +`unsupported` — deliberately *not* the 501 that `set-mode` answers for +the same code, because that asymmetry is the pre-existing contract. +`engine/session-load.js#activateFailureStatus` is the same table plus +an `unsupported → 501` row, which is again the pre-M3 mapping. And +`loadFailureWireCode` rewrites a "Resource not found" answer to +`session_not_found`, because `-32004` and `resource_not_found` do not +read as a session problem to a frontend; an undefined code stays +undefined so `JSON.stringify` drops the key exactly as before. + +**One module, two gate functions, rather than two modules.** B2 split +`engine/session-tree-reads.js` from `engine/session-export.js` because those two +endpoints declare *different* capabilities and their gate mechanics +differ for unrelated reasons. Here both endpoints share one capability, +one store, one client state and one route module, and the mechanics are +the two functions every other family already uses; splitting would +duplicate the transport table, the resolver and the two status mappers +to preserve a distinction that is one `enforcement` field wide — the +same shape B5's mixed `engine/session-writes.js` table already carries. + +**Three things this batch records as known debt instead of deciding:** + +1. **#71's semantic collapse is undecided, and this batch's only move + was to not decide it.** Both branches are costed in the module + header. Collapsing #71 into "switch + resume" is very nearly the + composition of #3 and #70, but the cost is the *response shape*: + today's body is `{ok, activeSessionId, data}` where `data` is the + engine's raw reply, and a collapsed endpoint has no such reply to + forward, so it would have to grow B6's byte-pinned switch payload or + invent a new one — changing the frontend, the docs and both language + versions at once. It would also change the endpoint's meaning, since + "activate" today mutates nothing beyond the two lines above while + "switch" re-roots the workspace, the chat buffer and the context + counters; a frontend that keeps calling it as activate would suddenly + get a workspace change. The 501 branch is cheap to build — the hard + gate already exists in this very file for #70 — but it is a + user-visible behaviour change that needs the UI degradation (hide or + disable the entry point, not an error toast) and it would fire for + every provider without single-active-session semantics, which per + the plan is the in-process host the default runtime transport is + built on. The tie-breaker is product knowledge this batch does not + have: who calls #71, and what they expect to happen to the sidebar, + the chat buffer and the workspace when it returns 200. +2. **#13 kills a running turn without asking whether it may.** The + cascade runs on the viewed session's child without checking whether + that child belongs to a turn the user still wants. That is the + pre-facade behaviour and arguably the right one (the user pressed + stop), but "refuse to stop a turn that has not yet produced output" + and "escalate only after a second attempt" are both defensible + alternatives. The same shape is recorded in B5's known debt for the + delete family, where the mirror-image question is "refuse to delete a + running session" — between them they are one policy question about + running sessions that deserves one decision rather than two. +3. **#70's 501 is the gate's 501, not the route's.** `loadSession` + answers 500 for `code === "unsupported"`, while a provider that + declares `sessionCrud.loadSession` absent answers 501 with + `engineCapabilityHttpResponse`'s body. Two different 501s can reach + this one route and only the second has ever existed; the router's + central mapping is what keeps them from being confused for each + other. Worth confirming against the frontend before M4 registers a + provider that can trip it. A fourth, narrower item: the "Resource not + found" rewrite only matches the string form, so a numeric JSON-RPC + code would reach the frontend verbatim behind a 500 — both behaviours + are pinned as-is, because widening the regex changes a wire shape and + the wider question (normalise once in `mcode-rpc.js` for every + caller) is a change to the RPC wrapper's contract, not to this + endpoint. + ## 6.

`acp` 传输**没有引擎面**—— + `cliService.getMessages` 只能经 v2 目录 host 触达，而只有 `runtime` 传输会去 + 启动它，所以删掉探针会让默认传输上的回填、以及本批门禁所依赖的两传输测试矩阵的 + 一半变成空转；(b) 两种读**截断的东西不同**——探针读整个会话并把映射后的*行*截在 + 400 行 / 200KB，而 `getMessages` 是分页的、截断的是*消息*，只有先证明一个有界 + 消息页的尾部能产出同样的 400 行，两者才可互换；(c) **排序不是同一种排序**——探针按 + `created_at_ms ASC, rowid ASC`，`getMessages` 按 `MessageQueryService` 自己的键， + 并列时二者会分歧，而顺序翻转的转录就是被用户读错的转录；(d) **导出仍独占旧候选集** + ——B2 刻意把 `GET /api/sessions/:id/export` 留在仅旧探针集上，因为它的 + `mcode_unavailable` 形状被既有测试按字节钉在那三个候选上，而扩大导出的候选集会让 + 它的富化从「不可用」变成「有答案」，那是产品变更而不是迁移步骤。本批**真正**收拢的 + 是让探针看起来无法移除的那层耦合：`routes/sessions.js` 已完全不再提及 + `transcript.js`，读只有一条缝，候选清单成了引擎层的实现细节，而不是两个路由各自 + 导入的东西。剩下的工作是**换缝**，属于 **M4-1**——注册 ACP provider、从而让引擎面在 + 默认传输下可触达的那一批——并且应当与一份针对真实 v2 host 的等价性测试、 + 以及同一提交里扩大的导出探针集一起落地。 +2. **首次触达的覆盖记录仍是 webui 侧写入。** 一次裸 `mvs_` 切换会在 `sessions.json` + 里创建一条引擎一无所知的记录，于是引擎的会话列表与 webui 的包装列表是两个恰好 + 答案相同的不同问题。这是既有行为、本批未动；关掉它意味着决定会话身份归谁所有。 +3. **用量同步不受门控。** `applyMavisUsageToCs` 读的是 webui 自己的 mavis 表， + 因此不声明任何能力，其失败仍被吞掉、只留一条 debug 级告警。这种不对称——身份与 + 转录会降级、用量被静默丢弃——早于本批存在。给这里补上 `usageStats` 会用一份 + 「缺失时用户看不见任何变化」的能力声明去门控一个能用的端点；真正的问题是静默丢弃 + 到底是不是正确的产品行为，而那不是本批该定的。 + +#### 哪些端点经由门面路由（迁移步 M3 批次 B7） + +批次 B7 用两个模块收了四个端点，而这四个端点之间只有**两种**门控策略——这是第一批 +族内答案并不统一的批次。这个分裂是端点的事实，不是两种意见之间的妥协。 + +| 端点 | 门面函数 | 能力 · 子项 | 强制方式 | 取值来源 | +| --- | --- |

`POST /api/protocol/activate-session`（#71） | `engine/session-load.js#activateEngineSession` | `sessionCrud` · `activateSession` | 软——只报告 | `mcode-rpc.js#activateSession`，随后是客户端状态重绑 | + +**`cancelled` 不等于「提示词已停」。** `session/cancel` 是一条**通知**：引擎用 +`app.onNotification` 注册它并中止当前提示词的 `AbortController`，所以若以请求形式 +发过去会得到「Method not found」。通知没有回包，因此这里的一次成功意味着 +「已发出」——响应字段之所以叫 `cancelled` 是历史原因。#13 与 #69 刻意用不同方式 +回答它，且两种差异都被测试钉住：#13 把 `cancelled:true` 与 `hardKilled:false` +配在一起且从不升级；而 #69 在拒绝时配上一个指向真正能升级的那个端点的指针。 + +**`hardKilled` 报告的是第一次决策，不是进程状态。** 它恰在「注册过子进程**且** +温和路径没走通」（即 `child && !cancelled`）时为真——也就是 webui 在离开处理函数 +的路上调用了 `child.kill()`。它被写进响应体的时刻早于有界升级定时器可能触发的 +时刻，因此 `hardKilled:true` 从不证明任何东西已经死掉。同样的不对称也是为什么 +`note` 字符串即使在根本没发生任何 kill 的情况下（没有子进程、没有 session id） +仍然写着「hard kill（session/cancel 无法送达）」：这条 note 说的是温和路径 +**为何**没有发生，而不是之后发生了什么。两处措辞都是承重的，也都被钉住。 + +**升级是有界的，而那个界本身就是契约的一部分。** +`engine/interrupt.js#STOP_FORCE_KILL_MS` 是 5000 毫秒，它被导出是因为它属于契约取值 +而不是实现细节：这个窗口才是让「已停止」真正等于「已停止」的东西。本批迁移过来的 +那个文件跑的是 2000 毫秒；批次计划把该界转写为「abort 5s」，产品拍板 +（2026-10-03）采纳了计划书的取值，等于接受顽固子进程多拿三秒去做收尾、代价是 +「已经停了」多撒谎三秒。定时器上有两条承重的守卫。它被 `unref()`，因此一个未到期的 +停止定时器永远不会把进程吊住。它重新检查的是**在装定时器之前就已捕获**的裸 +`child_process` 句柄——`child.child` 很可能在此期间被运行器自己的 `stop()` 置空， +而在触发时刻读到被置空的句柄，会静默地跳过这整条级联存在的意义。 + +**两条作用域规则让级联打在正确的那个回合上。** 子进程查找被收窄到 +`(cid, cs.mcodeSessionId)`——是**正在查看的**那个会话的子进程，不是「这个标签页的 +任意子进程」，因为一个标签页可能同时跑两段对话，停止不能去打断另一个回合的子进程。 +而僵尸声明的重置在引擎层是**决策**而非改写：`engine/interrupt.js#stopLeftStaleClaim` +给出 `claimStale`，由路由在它为真时才执行 `resetThinkingClaim`，因为那个辅助函数与 +`routes/chat.js#handleSend` 共用，把它搬走会是对发送路由的第二次、不相干的改动。 + +**为什么中断族软门控。** #13 的升级是 webui 自己的子进程管理——那个子进程是 +webui 自己的运行器注册到 webui 自己的状态总线上的，杀它不咨询任何 provider。 +给 #13 硬门控，等于为了表达对「两机制端点里**温和那一半**」的怀疑，删掉用户 +摆脱卡死「思考中」面板的唯一出路。#69 本来就有一个诚实的「我做不到」的答案， +而且那就是它的成文契约：200 `{ok:true, cancelled:false, warning, code, killEndpoint}`； +一个没有中断面的 provider 产出的正是这个形状，所以硬门控只会把一个准确的 200 +换成 501，并教前端一个它今天并不拥有的形状。 + +**#70 是本批唯一的硬门控，其背后的不变量是一个顺序。** `createWebuiEntry` 往 +`sessions.json` 里加的那条侧栏条目，必须**在引擎应答的下游，绝不是它的对等物**。 +一个不能装载的 provider 不得留下指向引擎从未打开过的会话的侧栏条目，一次失败的 +装载同样不得留下——一份带着条目却没有会话的 200，正是 #110 要防的假成功。所以 +`engine/session-load.js#assertSessionLoadCapability` 抛错，`engine/errors.js` 里的 501 机制 +在这个端点上确实被用上，答案由路由层既有的集中映射给出——没有任何路由需要记得去 +捕获它。条目本身的幂等性**取决于 `mcodeSessionId` 匹配，而不是取决于调用方**： +对 webui 已包装过的会话再次调用会直接返回既有记录而不重新落盘，因此重复调用无法 +为同一段对话长出重复的侧栏条目。 + +**#71 软门控，是因为给它硬门控本身**就是那个尚未由人做出的决定**。** 一个 ACP 客户端 +只跟踪一个活动会话，所以「激活另一个」正是客户端被重新指向的方式；进程内 host +根本没有「单活动会话」这个概念；而计划书把这个端点的归宿写成二选一—— +「语义塌缩（cs 切换 + resume），或 501」。这是两种不同的产品，在这里选 501 那一支 +就是由一张能力表静默地选掉它，既没有变更记录也没有前端工作。所以 +`checkSessionActivateCapability` 只报告，路由逐字节保持迁移前的形状与状态码映射。 +这个端点的**意义**就是顺序：先 `cs.mcodeSessionId = sessionId`，再 +`sessions.js#resetContext`；两者颠倒，会让上下文面板继续描述用户刚离开的那个会话。 + +**三张状态映射表是分开的，其差异都被钉住。** +`engine/session-load.js#loadFailureStatus` 对 `no_client` 回 503、对 not-found/invalid +类错误回 404、对 `unsupported` 回 **500**——刻意**不**用 `set-mode` 对同一 code 回的 +501，因为那种不对称就是既有契约。`engine/session-load.js#activateFailureStatus` 是 +同一张表再加一行 `unsupported → 501`，同样是迁移前的映射。而 `loadFailureWireCode` +把「Resource not found」改写成 `session_not_found`，因为 `-32004` 与 +`resource_not_found` 在前端看来都不像会话问题；未定义的 code 保持未定义， +于是 `JSON.stringify` 照旧丢弃这个键。 + +**一个模块、两个门控函数，而不是两个模块。** B2 拆出 +`engine/session-tree-reads.js` 与 `engine/session-export.js`，是因为那两个端点声明的是**不同**能力、 +且门控机制因无关理由而不同。这里两个端点共用一份能力声明、一份存储、一份客户端状态 +和一个路由模块，机制也就是其他各族已经在用的那两个函数；拆开会把传输表、解析器和 +两张状态映射表各复制一份，只为保住一个宽度仅一个 `enforcement` 字段的区分—— +这正是 B5 那张混合的 `engine/session-writes.js` 表已经承载的形状。 + +**本批记为已知债而不予决定的三件事：** + +1. **#71 的语义塌缩未决，而本批唯一的动作就是不去决定它。** 两个分支的代价都写在 + 模块头里。把 #71 塌缩成「switch + resume」几乎就是 #3 与 #70 的复合，但代价在 + *响应形状*上：今天的响应体是 `{ok, activeSessionId, data}`，其中 `data` 是引擎 + `session/activate` 的原始回包，而塌缩后的端点没有这样的回包可转发，它要么长成 + B6 那份按字节钉住的 switch 载荷、要么另造一份——两者都会同时改动前端、文档与 + 两个语言版本。它还会改变这个端点的**意义**：今天的「activate」除了上面那两行 + 之外不改 webui 的任何状态，而「switch」会重新生根工作区、chat 缓冲与上下文 + 计数器；一个继续按 activate 调用它的前端会突然得到一次工作区变更。501 那一支 + 造价很低——硬门控机制就在这个文件里、已经为 #70 建好——但它是一次用户可见的 + 行为变更，需要配套的 UI 降级（隐藏或禁用入口，而不是弹一个错误提示），而且它会 + 对**每一个**没有单活动会话语义的 provider 触发；按计划书，那恰恰就是默认 + runtime 传输所建立的那个进程内 host。打破平局需要的是本批并不具备的产品知识： + 谁在调 #71，以及当它返回 200 时，他们期望侧栏、chat 缓冲和工作区发生什么。 +2. **#13 不问一声就杀掉正在跑的回合。** 级联作用在正在查看的那个会话的子进程上， + 却不检查那个子进程是否属于用户仍想要的回合。那是门面前的行为，也可以说正是 + 正确的行为（用户按了停止），但「拒绝停止尚未产出任何输出的回合」与「第二次尝试 + 之后才升级」都是站得住的替代方案。同一形状也记在 B5 关于删除族的已知债里， + 那里镜像的问题是「拒绝删除一个正在跑的会话」——两者其实是同一个关于运行中会话 + 的策略问题，值得一次决定而不是两次。 +3. **#70 的 501 是门控的 501，不是路由的 501。** `loadSession` 对 + `code === "unsupported"` 回 500，而一个声明 `sessionCrud.loadSession` 缺失的 + provider 回的是 501 加 `engineCapabilityHttpResponse` 的响应体。两种不同的 501 + 都可能到达这一条路由，而只有后者曾经存在过；正是路由层的集中映射让二者不被 + 彼此混淆。在 M4 注册某个能触发它的 provider 之前，值得与前端确认一次。另有 + 一条更窄的：`Resource not found` 的改写只匹配字符串形式，因此一个数字型 JSON-RPC + code 会以 500 状态原样抵达前端——两种行为都按现状钉住，因为放宽正则会改动一份 + wire 形状，而更大的问题（是否在 `mcode-rpc.js` 里为所有调用方统一归一化）是 + 对 RPC 包装层契约的改动，不是对这个端点的改动。 + ## 6. 前端拓扑 ``` From 4d904c30659242d6024885e2153e2c2754978e4e Mon Sep 17 00:00:00 2001

This commit ships the PURE layer of the #12 send family: the streamingSend capability declaration, the HARD gate that enforces it, and the eight derivations that turn the runtime's stream vocabulary into webui's chat-line vocabulary. NO USER-VISIBLE CHANGE. The gate and the derivations are in place and tested, but nothing calls them: POST /api/send is not wired to a runtime branch yet and behaves exactly as it did at 32277c3a on every transport. Both the acp and the runtime failure sets are the pre-existing baseline core. M3-B8b adds the runner and the route branch and lights the transport up. The family gates HARD, the first M3 family to do so, because #12's response is {ok:true} written BEFORE the engine is called: a provider with no send surface could only be answered with an ack for a turn that never runs, and there is no truthful degradation to fall back to. The gate is deliberately unreachable today (v2 declares streamingSend: full; acp has no registered provider until M4), and the suite pins both halves of that so making it reachable is a deliberate edit. --- packages/webui/server/engine/index.js | 41 +- .../webui/server/engine/streaming-send.js | 799 ++++++++++++++++ .../test/lib/engine/streaming-send.test.js | 884 ++++++++++++++++++ release/public-source.json | 2 + 4 files changed, 1723 insertions(+), 3 deletions(-) create mode 100644 packages/webui/server/engine/streaming-send.js create mode 100644 packages/webui/test/lib/engine/streaming-send.test.js diff --git a/packages/webui/server/engine/index.js b/packages/webui/server/engine/index.js index d844df2e..de340149 100644 --- a/packages/webui/server/engine/index.js +++ b/packages/webui/server/engine/index.js @@ -36,9 +36,11 @@ // catalogue host itself is now reached through this facade too // (engine/host.js), so the plugins and turn-diff routes no longer name // lib/acp-client.js.

What this file owns is the part that is: which +// line each event produces, which line family the accumulator is +// currently in, and the two predicates the drain and the run-mirror +// consult. Two of the three red lines have their judgement expressed +// here as pure functions (`sendStillViewing`, `rewriteDrainedAnswerLine`) +// precisely so that the runner cannot re-derive them differently. The +// third — the draft promotion — is deliberately NOT re-derived here; +// the module explains why at the point where it would have gone. +// +// The fourth red line, the 409 claim, is entirely the route's and is +// taken before any transport branch exists. What this file contributes +// to it is the gate, which a future batch will call at the same place. +// +// Why this family's gate is HARD, which is the opposite of B7's. B5 +// and B7 gate soft because both endpoints have a truthful degradation: +// a stop whose escalation is webui's own child management can still +// stop the turn, and a cancel already HAS a documented "I could not +// do it" 200. #12 has no degradation at all. Its response is +// `{ok:true}` written BEFORE the engine is called — fire-and-forget by +// contract, because the output arrives on a different channel. A +// provider with no `streamingSend` surface cannot produce a truthful +// answer to any of: the turn never runs, the panel shows 思考中 with no +// stream behind it, and nothing resets the claim. That is #110's fake +// success exactly, so the gate throws and `app.js#invokeHandler` maps +// it to 501 with the shared payload. The gate is UNREACHABLE on both +// transports today — v2 declares `streamingSend: full`, and `acp` has +// no registered provider at all (M4's registry) — so no existing +// response changes, and B8a changes none either because nothing calls +// the gate yet. The suite pins both halves of that sentence, so making +// it reachable is a deliberate edit rather than a discovery. +// +// What this file deliberately does NOT do: +// +// - It does not run a turn. There is no runner, no host access and no +// IO here at all: every export below is a total function over its +// arguments. The data plane is B8b's. +// - It does not own the run claim, the run-mirror buffer, the drain +// or the draft promotion. Those are the route's and the state +// bus's, and moving them would be a second, unrelated change to +// the most fragile tail in the server. +// - It does not construct a host. `Never build a second host` is not +// even at stake: there is no host reference in this file. +// - It does not own the ACP path. `runMcodeAcp` and +// `streamAcpPrompt` are not imported, referenced or reached from +// here. +// +// Boot-path weight.

It adds the half B8a deliberately left out: the runner, the route branch, and the data plane that opens a turn's event stream. The acp path is unchanged. runMcodeAcp and streamAcpPrompt were not edited, and the route's post-run tail — the finalize drain, promoteDraftToMcodeSid, persistCurrentChat, pushStateFor — is untouched, because the runtime runner resolves to the same result shape and writes through the same run-chat buffer. That is what makes run-mirror, the drain and the single-identity promotion structural rather than re-implemented: they cannot differ between transports. MCODE_USE_ACP=0 still outranks the new branch, as lib/config.js documents — the escape hatch exists for the moment a transport misbehaves, so an operator must not have to unset a second variable first. The three route-level test files that install a fake ACP transport now pin MCODE_WEBUI_TRANSPORT=acp at module scope. Before B8b the send endpoint had no sibling to follow, so no test had to declare which transport it was written against; that declaration is what stops an acp-path contract from silently becoming a runtime-path one. Recorded in engine/streaming-send.js: /api/stop cannot stop a runtime turn and says so; attachments reach the runtime without a mime type; the context limit is not bridged from the stream; a first runtime turn does not receive the user's model pick; transport selection is still an env read rather than a registry lookup. --- packages/webui/server/engine/index.js | 34 +- .../webui/server/engine/streaming-send.js | 227 +++- packages/webui/server/lib/mcode-acp.js | 577 ++++++++++ packages/webui/server/routes/chat.js | 68 +- packages/webui/test/helpers/_setup.js | 19 + packages/webui/test/helpers/pin-transport.mjs | 40 + .../test/lib/engine/streaming-send.test.js | 1021 ++++++++++++++++- .../test/routes/chat-failed-send.check.mjs | 9 + .../chat-first-turn-session-guard.check.mjs | 9 + .../test/routes/chat-run-mirror.check.mjs | 9 + .../test/routes/send-runtime-e2e.test.js | 244 ++++ release/public-source.json | 2 + 12 files changed, 2156 insertions(+), 103 deletions(-) create mode 100644 packages/webui/test/helpers/pin-transport.mjs create mode 100644 packages/webui/test/routes/send-runtime-e2e.test.js diff --git a/packages/webui/server/engine/index.js b/packages/webui/server/engine/index.js index de340149..a0182e36 100644 --- a/packages/webui/server/engine/index.js +++ b/packages/webui/server/engine/index.js @@ -37,10 +37,9 @@ // (engine/host.js), so the plugins and turn-diff routes no longer name // lib/acp-client.js.

The exemption is exactly two named ids — never a prefix, never a default — and it does not survive a `none`: a provider with no `authCredentials` at all has no dedicated writer either. + +**What the user sees.** The permission-mode selector and the model selector are hidden, not disabled and not accompanied by an error message (`webapp/lib/engine-capabilities.ts`, wired in `webapp/components/composer.tsx`).

So the gate's +// sub-item is a function of the request: the two bridged ids ask +// for their own sub-item and pass a provider that denies the +// generic one, and every other config id asks for `setConfigOption` +// and gets the 501. `MODE_WRITE_BRIDGED_CONFIG_IDS` is that table, +// exported because the frontend needs the same names to decide +// which controls to hide (see `webapp/lib/engine-capabilities.ts`, +// and the tripwire test that pins the two tables to each other). +// +// What the two 501s on these routes now are, and why they must not be +// confused. B7 recorded the same collision for #70 and this batch adds +// two more instances of it, so it is worth stating flatly: +// +// - THE ENGINE-GATE 501 (new). Body: +// `{ok:false, code:"engine_capability_not_supported", capability, +// provider, missing?, reason?, error}` from +// `errors.js#engineCapabilityHttpResponse`, written by the router's +// central mapping. It has NO `fallback` field, and it is not +// reachable from the route's own code path at all — the route never +// catches it. +// - THE ROUTE'S 501 (pre-existing). Body: +// `{ok:false, error, code:"unsupported", fallback:"send_plan_as_prompt"}` +// (plus the 501 shape #68 already had, without `fallback`). This +// one is the ENGINE refusing a call it does accept, and it is +// preserved byte for byte. +// +// The gate's 501 losing `fallback` is deliberate and is the one place +// where this batch's behaviour change is visible to a client that +// special-cases the field: design §4.2 says the UI hides the entry +// point rather than falling back to a degraded action, and a capability +// that is not there has no degraded action to fall back TO — offering +// `send_plan_as_prompt` from a 501 that says "there is no way to enter +// plan mode here" would be advertising a workaround for a missing +// feature. The engine's own refusal keeps its hint because there the +// feature exists and only this call did not work. KNOWN DEBT 1. +// +// What this file deliberately does NOT do: +// +// - It does not own the client-state writes. `cs.planMode` (#67) and +// `cs.permissions` (#68) are webui's own view of the client, and +// the state push is a transport concern; both stay in the route, +// which is also what keeps them running only on success. +// - It does not own the 400s. A missing `sessionId` / `mode` / `key` +// is caller confusion, not an engine limitation, and the matrix +// says an unknown provider id answers 404 for the same reason. +// - It does not build a host. There is no host on this path. +// - It does not migrate `/api/set-model` and `/api/permissions`, +// which are B10's two endpoints.

Its reporting +sibling, `engine/streaming-send.js#checkStreamingSendCapability`, never +throws a capability error: a typo in webui's own endpoint key is a plain +`Error`, because caller confusion is not a capability question and the +HTTP layer must never answer 501 for a bug in this repository. + +**Why two batches for one endpoint.** B8a shipped the declaration, the +gate and the derivations as a layer with no runner and no route branch — +nothing user-visible changed and nothing called the gate, so a module +whose entire value is that it has no IO could be reviewed on its own. +B8b added the data plane at the bottom: the one place in the family that +touches the engine, plus the route's third branch. The split mattered +because the purity was provable only while it held — +`engine/streaming-send.js#openEngineSendStream` and +`engine/streaming-send.js#projectSendAttachments` are the only exports +that are not total functions over their arguments, and they are the only +reason the module now reaches for `await import()`. + +**The escape hatch still wins.** The branch in `chat.js#handleSend` is +ordered, and the ordering is load-bearing: + +| Condition | Runner | Stream source | +| --- | --- | --- | +| `MCODE_USE_ACP === "0"` | `runMcodeExec` (exec) | none — a non-streaming runner with no run-mirror | +| `MCODE_WEBUI_TRANSPORT === "runtime"` | `mcode-acp.js#runMcodeRuntime` → `mcode-acp.js#streamRuntimePrompt` | runtime frames, already projected to `TuiStreamEvent` | +| otherwise (the default `acp`) | `mcode-acp.js#runMcodeAcp` → `mcode-acp.js#streamAcpPrompt` | `mcode acp` session-update notifications | + +`MCODE_USE_ACP=0` is evaluated first because `lib/config.js` documents +the precedence as "transport=exec regardless of `MCODE_WEBUI_TRANSPORT`", +and that is the right order for the thing the variable is: the escape +hatch exists for exactly the moment a transport is misbehaving, so an +operator who reaches for it must not have to unset a second variable +first. The runtime branch passes the **same** options object the acp one +does, `owningWebuiSessionId` included, which is what makes the whole tail +below that line transport-agnostic — both runners return the same `r` and +write through the same `state-bus.js#createRunChat` buffer. + +**Why this family gates HARD, and where the gate is called.** #12's +response is `{ok:true}` written *before* the engine is called — +fire-and-forget by contract, because the output arrives on a different +channel. That is exactly what makes the gate hard, and it is the mirror +image of B7: a stop whose escalation is webui's own child management +still stops the turn, and a cancel already has a documented "I could not +do it" 200, so both have a truthful degradation. #12 has **none**. A +provider with no `streamingSend` surface cannot produce a truthful answer +to any of the three things a user would notice — the turn never runs, the +panel shows 思考中 with no stream behind it, and nothing resets the +claim. That is #110's fake success in its purest form, so +`engine/streaming-send.js#assertStreamingSendCapability` throws and +`app.js#invokeHandler` maps it to 501 with +`engine/errors.js#engineCapabilityHttpResponse`'s shared body. The route +builds nothing: no response code is added to `chat.js#handleSend` at all. + +**The gate sits before `state-bus.js#beginRun`, and that is the second +half of the argument.** The throw would otherwise land outside the `try` +whose `finally` calls `state-bus.js#endRun`, and a leaked claim refuses +every later send in that conversation with a 409 that names a turn +nobody is running. A gate that protects against a fake success by +creating a permanent fake busy is worse than no gate, so the call site +is `chat.js#handleSend`'s, at exactly one place, immediately before the +claim. + +**The gate is currently unreachable, and that is stated rather than +assumed.** `engine/streaming-send.js#providerByTransport` maps only +`runtime` to a registered provider id; the default `acp` transport has +none yet, because the registry is M4's. So under `acp` the gate answers +`unregistered-transport` and returns without throwing — the pre-M3 +behaviour, not a hole — and under `runtime` the local-runtime-v2 provider +declares `streamingSend: full`, so the answer is `checked`. The suite +pins both halves, which makes "the provider no longer declares a send +surface" a deliberate edit rather than a discovery. The table is built +per call rather than frozen at module scope, because +`engine/index.js` re-exports this module and a module-level table would +read `engine/index.js#DEFAULT_ENGINE_PROVIDER_ID` while that binding is +still in its temporal dead zone on a cold import. + +**The bridge joins two vocabularies, and it starts above the wire.** +ACP delivers an *event* vocabulary (`thought` / `message` / `tool_call` / +`tool_update` / `plan_update`) that happens to sit close to webui's line +syntax. The runtime delivers a *frame* vocabulary (SSE `dataJson` +envelopes) that webui has never consumed — but the per-turn wrapper in +`runtime-host.js` already projects those frames into structured +`TuiStreamEvent`s, so `engine/streaming-send.js` starts one level above +the wire and never sees a frame. `engine/streaming-send.js#SEND_EVENT_KINDS` +is webui's own vocabulary, not the runtime's: `thought` / `message` / +`tool` are the three families the ACP path accumulates separately, +`authoritative` is the settled message that **overwrites** the accumulator +instead of appending to it (the runtime emits deltas *and*, at close, one +complete message — the same fact `result.answer` delivers once instead of +thousands of times), `terminal` is a turn outcome, and the rest are facts +about the stream that produce no line at all. + +**The classification never throws, and that asymmetry is deliberate.** +`engine/streaming-send.js#classifySendEvent` returns +`{kind: ignore}` for a shape it does not recognise rather than killing a +turn that is otherwise streaming correctly. A bridge that throws on an +unknown frame turns every future runtime addition into an outage of the +chat endpoint, which is strictly worse than not rendering one line. + +**Four properties carry the weight, and all four are stated as shared +functions rather than re-derived per transport.** + +1. **The still-viewing test has three forms.** + `engine/streaming-send.js#sendStillViewing` is the single predicate + both runners consult, at bind time and at finalize time. Mid-turn the + user can switch conversations, which re-points `cs` at *another* + record, and a `cs` mutation after that point would stamp this turn's + engine id or title onto the session the user switched **to**. The + three forms are: no owning record id at all (a direct caller, not a + route — treat as still viewing); `cs.sessionId` equals the owning + record id (the pre-promotion form); `cs.sessionId` equals the engine + sid (the post-promotion form, because the record was renamed to the + engine id at bind time). Anything else means the user switched away, + and the turn's lines go to the owning record through + `sessions.js#promoteDraftToMcodeSid`'s sibling path instead of to the + viewed `cs.chat`. +2. **The finalize drain rewrites the last `●` line, over a detached + list.** `state-bus.js#drainRunChat` hands the route a copy of the + run's lines, and `engine/streaming-send.js#rewriteDrainedAnswerLine` + mirrors the route's in-place rewrite, which only ever runs while the + user is still viewing; the runtime path needs the same operation over + a detached array, because a turn that ended while the user was + elsewhere must still record its final answer against the run's own + lines rather than the other session's chat. Two behaviours are + load-bearing: the + **last** `●` line wins, scanning from the end, because a turn with a + tool call between two answer segments has more than one; and when + there is none the answer is **appended**, because dropping it would + lose the turn's only output on a runtime that streams no `●` at all. + The function is pure — the input array is never mutated — so a caller + can compare before and after. +3. **The draft promotion is deliberately *not* re-derived.** This is the + one red line with no predicate in the module, and its absence is the + decision. The promotion's condition — "the viewed session has an + engine id" — is already correct for both transports, because + `sessions.js#promoteDraftToMcodeSid` is itself a no-op when + `cs.sessionId === cs.mcodeSessionId`, which is the post-bind state of + every turn. Narrowing it with a second predicate would be a behaviour + change on the acp path — the survival condition — in exchange for a + guarantee the existing guard already makes. Its evidence is a route + test, not a function, and the suite pins that no such predicate exists. +4. **The 409 claim is keyed by `(cid, sessionId)`, and the runtime + branch does not change it.** `state-bus.js#beginRun` is called with + the conversation key, not `cid` alone, so a long turn in one + conversation does not refuse sends in every other conversation of the + same tab; a second send into the *same* conversation is still the + duplicate-execution guard and is still refused. The runtime runner + keeps the same three mechanics the ACP runner has: the owning webui + record is captured before the first await, the draft→engine bind goes + through the same two helpers, and the first-turn session-busy guard + is backfilled with `state-bus.js#updateRunSid` at the same instant — + because the route claimed the run before the turn existed, so on a + session's first turn the claim was registered with `sid: null` and + the engine-session guard never covered it. + +**The line grammar has exactly one home, which is why the runtime path +reuses the ACP reducer instead of writing a second one.** Tool calls go +through `mcode-acp.js#applyToolUpdate`, so the indented body syntax, the +`@ path` lines, the `! error` line and the subagent-detection wiring are +inherited by producing the same input; a second implementation would be a +second place for the `→ name` header to disagree with the body beneath +it. Two details are the runtime's own judgement and are pinned +separately. Stage mapping: `engine/streaming-send.js#sendToolUpdate` +reads the numeric +`ToolCallStatus` and maps the still-moving stages to `pending` (a body +here would print a half-streamed argument as if it were the tool's +input), `finished` to `completed` and `failed` to `error` — the ACP +path's own words. And header emission: the runtime re-sends the whole +call on every chunk of its lifecycle, so a call already announced +contributes no second `→ name`; the header for a new id is written by the +runner through `engine/streaming-send.js#sendToolHeaderLine` with its +arguments — which the reducer's synthesized header deliberately omits — +and the index is pre-registered so the reducer takes its "header already +known" branch and writes only the body. The double space in +`→ name ` is transcribed rather than tidied, because that spacing +is what the ACP line looks like and what the decoder splits on. + +**The stream is closed exactly once, and "it just stopped" is a +failure.** `mcode-acp.js#streamRuntimePrompt` is structurally the same +machine as `mcode-acp.js#streamAcpPrompt`: an accumulator `r`, a +per-event write into the run-chat buffer through +`chat-line.js#streamUpdateLine` (the same "replace the line with this +prefix, otherwise append" primitive both transports use), a bounded idle +watchdog, and a +`finalize()` guarded by a `_finalized` flag. The runtime's per-turn +wrapper converts an engine throw into an `{type:"error"}` frame rather +than a rejected iterator, so the loop never has to distinguish "the +engine crashed" from "the engine reported a crash" — and a stream that +ends with no terminal event at all is recorded as `failed`, not as +success, because treating a truncated turn as a complete one renders an +unfinished answer as a finished one. The same finalize appends the +`§§` marker lines, strips the `▍` streaming cursor, closes the per-turn +host, re-queries the mavis usage tables and reads the title back; the +title read-back and the usage re-query are the *same* calls the ACP +finalize makes, because both are already transport-aware, and duplicating +them here would be a second copy of a decision `acp-client.js` already +makes. + +**One pure function is where the "invisible" regressions live.** +`engine/streaming-send.js#sendSegmentAdvance` is the piece easiest to get +subtly wrong and the hardest to notice when it is: a missing reset makes +the next `●` line contain every previous segment's text, which still +renders and still looks like an answer. The rule matches the ACP path's +own `lastChunkKind` discriminator — a delta of the same family appends to +the buffer, a delta of a different family (or of any family after a tool +call) starts a fresh segment. The two other small mappings are pinned in +the same spirit: `engine/streaming-send.js#sendTerminalOutcome` reports +`aborted`/`interrupted` as `aborted` and **not** as a failure, because +the user pressed stop and firing an error alert for a user action is +wrong; and `engine/streaming-send.js#sendUsageTotals` returns `null` +rather than a zeroed object, because the finalize's "no usage" branch is +what falls back to a length-based estimate and a zeroed object would take +that branch away and leave the context panel reading zero tokens. + +**Boot-path weight stayed flat.** `chat.js` imports the module, so it is +on the boot path, but its static imports are `engine/capabilities.js`, +`engine/index.js` and the node builtins — all cheap. The host getter, the +per-turn host wrapper and the attachments helper are reached through +`await import()` inside `engine/streaming-send.js#openEngineSendStream` +and nowhere else, so an acp-only server never boots the runtime graph. +That is the M1 lesson, and it is what lets the module be re-exported from +the facade at all. + +**Eight things this batch records as known debt instead of deciding:** + +1. **The hard gate is declared but not exercised.** It is unreachable on + both transports today — the local-runtime-v2 provider declares + `streamingSend: full`, and `acp` has no registered provider at all — + so the honest description of the 501 is "a policy that is stated, + tested in isolation, and not yet reachable". The suite pins both + halves of that sentence, so making it reachable is a deliberate edit + rather than a surprise. +2. **`resync-required`, `messages-replaced` and `messages-rewound` are + all classified as ignored.** The runtime can tell webui that its view + of the turn diverged — that is what `resync-required` means — and + webui keeps the last rendered line buffer and says nothing to the + user. The runner's only surface is a log line, which is the right + minimum but not a resolution. Whether webui should re-derive the turn + from the engine's own spine on a resync is a product question, and it + interacts with the mirror-retirement work in `transcript.js` (#126), + where the question of which lines are authoritative is already being + re-argued. Deciding it twice, in two files, is how the two answers + drift. +3. **The bridge produces a lossy mirror, deliberately.** `●` carries a + single flattened line and `→ name` carries the call's arguments as they + were at first sighting — the same lossy form the ACP path has always + produced, and producing anything richer here would make the two + transports' transcripts incomparable. The consequence is that the + #126 mirror-retirement criterion must recognize the **runtime form** of + a lossy mirror as well as the ACP one; the two are the same fact, so + the criterion should be written once against the line grammar rather + than twice against the transports. +4. **`/api/stop` cannot stop a runtime turn, and it says so.** The + runtime runner registers no active child, because the runtime has no + subprocess for B7's kill cascade to signal, and inventing a second + interrupt protocol outside B7's family would be a worse answer than + none. A user pressing stop under the runtime transport therefore gets + B7's documented degradation: the gentle `session/cancel` refuses + (there is no ACP client), no child is registered so `hardKilled` is + false — and `engine/interrupt.js#stopLeftStaleClaim` is true, so the + route resets the thinking claim and pushes an at-rest state. The panel + recovers; the turn keeps running in the runtime. That is a truthful + "I could not stop it", and it is strictly better than the alternative, + but it is not "stopped". The fix belongs to B7's family — route + `abortSession` through the facade when the transport is `runtime`, the + way the interrupt gate already resolves the provider for that family. + Until then the runtime transport has no user-reachable abort, and that + difference between transports is a product decision about when + `runtime` becomes the default, not a refactor. +5. **Attachments reach the runtime without a MIME type.** webui's upload + pipeline (`attachments.js#resolveAttachment`) keeps `{path, name, size}` + and discards everything else, so + `engine/streaming-send.js#projectSendAttachments` sends + `application/octet-stream` — a truthful default rather than a guess, + and a real limitation, because a runtime that dispatches on MIME type + will treat an image as a file. The fix is upstream of this module (retain + the type at upload time) and changes the stored record shape, so it is + a separate change with its own compatibility question. +6. **The context limit is not bridged from the stream.** The runtime's + `TokenUsage` carries `context_window`, but the TUI projection does not + forward it, so `engine/streaming-send.js#sendUsageTotals` can produce + the three totals the finalize accumulates and nothing for + `cs.context.limit`. The limit therefore arrives, as it does on acp, + only through the post-finalize mavis re-query. Writing a projection + change in the TUI package from a webui batch would invert the + dependency direction the M1 split established, so it is recorded + rather than done. +7. **The runtime does not receive the user's model pick.** The ACP + runner pre-applies a recorded model to a brand-new session so the + engine runs the model the chip claims; the runtime runner does not, + because that helper speaks ACP's `session/set_config_option` and the + runtime's equivalent belongs to a later batch. So under `runtime` a + *first* turn runs the runtime's own default and the chip may disagree + — the exact defect the pre-apply was written to prevent, bounded to a + session's first turn. The disagreement is visible rather than silent, + and `runtime` stays opt-in until that lands. +8. **Transport selection is an env read, not a registry lookup.** The + branch in `chat.js#handleSend` compares `MCODE_WEBUI_TRANSPORT` + against the literal `"runtime"`, where the plan says selection should + read the provider registry. M4 owns the registry, and hard-coding a + second place that knows provider ids before one exists is precisely + the thing M4 exists to remove. This batch deliberately does not create + a premature registry. + ## 6.

+拉它的人不该还得先取消另一个变量。runtime 分支传的是与 acp 分支**同一个**选项对象， +其中就包含 `owningWebuiSessionId`——正是它让该行以下的整条尾巴都与传输无关：两个 +运行器返回同一个 `r`，并写进同一份 `state-bus.js#createRunChat` 缓冲。 + +**为什么这一族是硬门控，以及门控在哪里被调用。** #12 的应答是 `{ok:true}`， +写在调用引擎**之前**——按契约是 fire-and-forget，因为输出走的是另一条通道。这恰恰是 +它必须硬门控的原因，也正好是 B7 的镜像：一个停止请求的升级动作是 webui 自己的子进程 +管理，因此它仍然停得掉那个回合；一个取消端点本来就有一个成文的「我做不到」200。 +而 #12 **一个都没有**。一个没有 `streamingSend` 面的 provider，无法对用户会注意到的 +三件事给出任何如实答案——回合根本没跑、面板显示「思考中」而背后没有任何流、声明 +没有任何东西去重置。这就是 #110 那个假成功最纯粹的形态，所以 +`engine/streaming-send.js#assertStreamingSendCapability` 抛错，由 `app.js#invokeHandler` +映射成 501 加 `engine/errors.js#engineCapabilityHttpResponse` 那份共享响应体。路由 +自己什么都不构造：`chat.js#handleSend` 里根本没有新增任何响应码。 + +**门控位于 `state-bus.js#beginRun` 之前，而这就是论证的另一半。** 否则那一次抛出 +会落在 `try` 之外，而释放声明的 `finally`（也就是 `state-bus.js#endRun`）就在那个 +`try` 里；一个泄漏的声明会让这段对话之后每一次发送都收到 409，而那个 409 描述的是 +一个根本不存在的回合。一扇为了防止 +假成功、却制造出永久假繁忙的门，比没有门更糟，所以调用点就在 +`chat.js#handleSend` 里、只有那一处，紧挨在认领之前。 + +**这扇门当前不可达，而这一点是被陈述出来的，不是被假定的。** +`engine/streaming-send.js#providerByTransport` 只把 `runtime` 映射到一个已注册的 +provider id；默认的 `acp` 传输目前一个都没有，因为那份注册表属于 M4。所以在 `acp` +下门控回的是 `unregistered-transport` 且不抛错——那是迁移前的行为，而不是门上的洞； +而在 `runtime` 下，local-runtime-v2 provider 声明了 `streamingSend: full`，于是答案是 +`checked`。测试把这半句和那半句都钉住了，这让「provider 不再声明 send 面」成为一次 +刻意编辑而不是一次意外。这张表是每次调用现建的，而不是在模块作用域里冻结，因为 +`engine/index.js` 会再导出这个模块，而模块级表在冷导入时会在 +`engine/index.js#DEFAULT_ENGINE_PROVIDER_ID` 仍处于暂时性死区的那一刻读到它。 + +**这座桥连接的是两套词表，而它是从协议线之上起步的。** ACP 送来的是一套**事件**词表 +（`thought` / `message` / `tool_call` / `tool_update` / `plan_update`），它碰巧与 webui +的行语法相当接近。runtime 送来的是一套**帧**词表（SSE 的 `dataJson` 信封），webui 从 +未消费过它——但 `runtime-host.js` 里的逐回合包装器已经把这些帧投影成结构化的 +`TuiStreamEvent`，因此 `engine/streaming-send.js` 从协议线之上一层起步，从头到尾没见 +过帧。`engine/streaming-send.js#SEND_EVENT_KINDS` 是 webui 自己的词表，不是 runtime 的： +`thought` / `message` / `tool` 是 acp 路径分别累积的三族，`authoritative` 是那条**覆盖** +而非追加到累加器上的已落定消息（runtime 既发增量、又在收尾时发一条完整消息——与 +`result.answer` 把同一件事说一次而不是上千次是同一个事实），`terminal` 是回合结局， +其余都是关于这条流、但不产生任何行的事实。 + +**分类永不抛错，而这种不对称是刻意的。** +`engine/streaming-send.js#classifySendEvent` 对不认识的形状返回 `{kind: ignore}`， +而不是掐掉一个本来流得很好的回合。一座遇到未知帧就抛错的桥，会把 runtime 未来每 +一次新增都变成聊天端点的一次故障，那严格地比少渲染一行更糟。 + +**四条性质承着重量，而且四条都被表述为共享函数，而不是每套传输各自重新推导一遍。** + +1. **still-viewing 判定有三种形态。** + `engine/streaming-send.js#sendStillViewing` 是两个运行器在绑定时与 finalize 时都会 + 查的那一个谓词。回合进行中用户可以切换对话，那会把 `cs` 重新指向**另一条**记录， + 而此后任何一次 `cs` 改写都会把本回合的引擎 id 或标题盖到用户刚切过去的那个会话上。 + 三种形态是：根本没有归属记录 id（直接调用方而非路由——按仍在查看处理）； + `cs.sessionId` 等于归属记录 id（提升前的形态）；`cs.sessionId` 等于引擎 sid + （提升后的形态，因为记录在绑定那一刻已被改名为引擎 id）。其余情况都意味着用户切走了， + 于是本回合的行改由 `sessions.js#promoteDraftToMcodeSid` 的那条姊妹路径写进归属记录， + 而不是写进正在查看的 `cs.chat`。 +2. **finalize drain 重写末条 `●` 行，且作用在一个已分离的列表上。** + `state-bus.js#drainRunChat` 把本回合行的副本交给路由， + `engine/streaming-send.js#rewriteDrainedAnswerLine` 则镜像路由那份就地改写——后者只在 + 用户仍在查看时才会跑；runtime 路径需要在脱离的数组上做同一件事，因为一个在用户 + 去往别处时结束的回合，仍必须把它的最终答案记在**本回合自己的**行上，而不是记在另一个 + 会话的聊天里。有两条行为是承重的：**最后**一条 `●` 行获胜，从尾部往前扫，因为一个 + 在两个回答段之间插了工具调用的回合不止有一条；而当一条都没有时，答案是**追加**， + 因为丢掉它就等于在一个根本不流 `●` 的 runtime 上丢掉这个回合唯一的输出。这个函数 + 是纯的——输入数组从不被改写——因此调用方可以拿改写前后作对比。 +3. **草稿提升被刻意*不*重新推导。** 这是三条红线里唯一在模块中没有对应谓词的一条， + 而它的缺席就是那个决定。提升的条件——「正在查看的会话有引擎 id」——对两套传输 + 本来就都是正确的，因为 `sessions.js#promoteDraftToMcodeSid` 自身在 + `cs.sessionId === cs.mcodeSessionId` 时就是空操作，而那正是每个回合绑定之后的状态。 + 再用第二个谓词去收窄它，等于拿存活条件（acp 路径的行为变更）去换一个既有守卫 + 本来就已经做出的保证。它的证据是一条路由测试而不是一个函数，测试同时钉住了这里 + 不存在这样一个谓词。 +4. **409 声明以 `(cid, sessionId)` 为键，而 runtime 分支没有改动它。** + `state-bus.js#beginRun` 是拿会话键调用的，而不是只拿 `cid`，因此一个标签页里某段 + 对话中的长回合不会连带拒掉同一标签页里其他对话的发送；而对**同一段**对话的第二次 + 发送仍然是那个重复执行守卫，仍然被拒绝。runtime 运行器保留了 ACP 运行器原有的三处 + 机制：归属 webui 记录在第一个 await 之前捕获、草稿→引擎的绑定走同样那两个辅助函数、 + 首回合的会话繁忙守卫在同一时刻用 `state-bus.js#updateRunSid` 补写——因为路由在回合 + 存在之前就认领了声明，所以某个会话的首回合上，那次声明是以 `sid: null` 登记的， + 引擎会话的守卫从未覆盖到它。 + +**行语法只有一个家，这正是 runtime 路径复用 ACP 归约器、而不是另写一份的原因。** +工具调用走 `mcode-acp.js#applyToolUpdate`，于是缩进正文语法、`@ path` 行、`! error` 行 +与子代理识别接线全都被「产出同样输入」这一件事继承下来；另写一份实现，就等于多出 +一个让 `→ name` 表头与它下面正文产生分歧的地方。有两处细节属于 runtime 自己的判断， +并被单独钉住。阶段映射：`engine/streaming-send.js#sendToolUpdate` 读取数字形态的 +`ToolCallStatus`，把仍在推进的阶段映射为 `pending`（此刻产出正文，等于把半流式参数 +当成工具输入打印出来），把 `finished` 映射为 `completed`、把 `failed` 映射为 `error`—— +都是 acp 路径自己的词。表头产出：runtime 会在一次调用的整个生命周期里反复重发整个 +调用，因此一个已经宣告过的调用不会贡献第二条 `→ name`；新 id 的表头由运行器通过 +`engine/streaming-send.js#sendToolHeaderLine` 连同它的参数写出——而归约器自己合成的 +那条表头刻意不带参数——同时把索引预先登记好，好让归约器走「表头已知」那一支、只写 +正文。`→ name ` 里那个双空格是照抄而不是整理的，因为那个间距正是 acp 行的样子， +也正是解码器据以切分的东西。 + +**这条流恰好关闭一次，而「它就这么停了」是一次失败。** +`mcode-acp.js#streamRuntimePrompt` 与 `mcode-acp.js#streamAcpPrompt` 在结构上是同一台 +机器：一个累加器 `r`、通过 `chat-line.js#streamUpdateLine` 逐事件写入 run-chat 缓冲 +（两套传输共用的那个「同前缀则替换该行、否则追加」的原子操作）、一个有界的空闲 +看门狗，以及一个由 `_finalized` 标志守卫的 `finalize()`。runtime 的逐回合包装器把引擎 +抛出的一次异常转成一个 `{type:"error"}` 帧而不是一次被拒绝的迭代器，因此这个循环永远 +不必去区分「引擎崩了」和「引擎报告了一次崩溃」；而一条没有以终止事件收尾的流会被记为 +`failed` 而不是成功，因为把一个被截断的回合当成完整回合，等于把一段没写完的回答渲染 +成一段写完的。同一份 finalize 还会追加 `§§` 标记行、剥掉 `▍` 流式游标、关闭逐回合 +host、重新查询 mavis 用量表并回读标题；标题回读与用量重查与 ACP finalize 调的是 +**同样那两个调用**，因为两者都已经具备传输感知，而在这里复制一份，就是把 +`acp-client.js` 已经做过的决定再做一遍。 + +**有一处纯函数正是「不可见」回归的所在。** +`engine/streaming-send.js#sendSegmentAdvance` 是最容易悄悄弄错、而出错时最难被察觉的 +那一块：漏掉一次重置，会让下一条 `●` 行包含此前每一段的文本，而它照样渲染、照样看起来 +像一条像样的回答。这条规则与 acp 路径自己的 `lastChunkKind` 判别器一致——同族的增量 +追加到缓冲，不同族的增量（或任何出现在工具调用之后的增量）另起一段。另外两个小映射也 +以同样的方式被钉住：`engine/streaming-send.js#sendTerminalOutcome` 把 +`aborted`/`interrupted` 报成 `aborted` 而**不是**失败，因为那是用户按了停止，为一次用户 +动作弹出错误提示是错的；而 `engine/streaming-send.js#sendUsageTotals` 返回 `null` 而不是 +一个清零的对象，因为 finalize 里「没有用量」那一支才是回退到按长度估算的地方，一个 +清零对象会把那一支拿走，让上下文面板一直显示零 token。 + +**启动路径的重量保持不变。** `chat.js` 会导入这个模块，所以它在启动路径上；但它的静态 +导入只有 `engine/capabilities.js`、`engine/index.js` 与 node 内建模块——全都便宜。host +getter、逐回合 host 包装器与附件辅助函数只通过 `await import()` 在 +`engine/streaming-send.js#openEngineSendStream` 内部被触达，别处一概没有，因此一台 +纯 acp 的服务器永远不会把 runtime 那张图启动起来。这就是 M1 的教训，也正是这个模块 +之所以能够从门面上再导出的原因。 + +**本批记为已知债而不予决定的八件事：** + +1. **硬门控已被声明，但从未被触发。** 它在两套传输上都还不可达——local-runtime-v2 + provider 声明了 `streamingSend: full`，而 `acp` 根本没有已注册的 provider——因此关于 + 那个 501，诚实的描述是「一条被陈述、被隔离测试、但尚不可达的策略」。测试把这句话的 + 两半都钉住，于是让它变得可达是一次刻意编辑而不是一次意外。 +2. **`resync-required`、`messages-replaced` 与 `messages-rewound` 全都被归为忽略。** + runtime 可以告诉 webui 它对本回合的视图已经分叉——那正是 `resync-required` 的含义 + ——而 webui 保留最后一次渲染出的行缓冲，什么都不对用户说。运行器唯一的出口是一行 + 日志，那是正确的下限，但不构成一个解法。遇到 resync 时 webui 是否应当从引擎自己的 + 骨架重新推导出这个回合，是一个产品问题，而且它与 `transcript.js`（#126）里的镜像退役 + 工作相互纠缠——那里「哪些行才是权威的」这个问题已经在被重新辩论。在两个文件里各 + 决定一次，正是两个答案产生漂移的方式。 +3. **这座桥刻意产出一个有损镜像。** `●` 承载一条被压平的行，`→ name` 承载的是首次 + sighting 时那个调用的参数——正是 acp 路径一直产出的那种有损形态，而在这里产出任何 + 更丰富的东西，都会让两套传输的转录变得不可比。其后果是：#126 的镜像退役判据必须 + 同时认出有损镜像的 **runtime 形态**与 acp 形态；两者是同一个事实，所以这条判据应当 + 针对行语法只写一次，而不是针对两套传输写两次。 +4. **`/api/stop` 停不掉一个 runtime 回合，而它如实这么说。** runtime 运行器不注册任何 + 活动子进程，因为 runtime 没有子进程可供 B7 的 kill 级联去发信号，而在 B7 那一族 + 之外另造一套中断协议，比没有答案更糟。因此在 runtime 传输下按停止的用户拿到的是 B7 + 那个有文档的降级：温和的 `session/cancel` 被拒绝（没有 ACP 客户端），没有子进程被 + 注册，所以 `hardKilled` 为假——而 `engine/interrupt.js#stopLeftStaleClaim` 为真，于是 + 路由重置思考声明并推送一个静止态。面板恢复了；回合在 runtime 里继续跑。那是一句如实的 + 「我停不掉它」，严格地优于另一种选择，但它不等于「已停止」。修法属于 B7 那一族——当 + 传输是 `runtime` 时把 `abortSession` 也经由门面路由，就像中断门控已经为那一族解析 + provider 那样。在那之前 runtime 传输没有任何用户可达的中止，而两套传输之间的这个 + 差异，是关于 `runtime` 何时成为默认传输的产品决定，不是重构。 +5. **附件到达 runtime 时没有 MIME 类型。** webui 的上传流水线 + （`attachments.js#resolveAttachment`）只保留 `{path, name, size}`，其余全部丢弃，因此 + `engine/streaming-send.js#projectSendAttachments` 送出的是 + `application/octet-stream`——一个如实的默认值而不是猜测，同时也是一条真实限制：按 + MIME 类型分派的 runtime 会把图片当成文件。修法在本模块上游（在上传时留存类型），且 + 会改变已存记录的形状，因此那是另一次带自己兼容性问题的改动。 +6. **上下文上限没有从流里桥接过来。** runtime 的 `TokenUsage` 带有 `context_window`， + 但 TUI 投影没有转发它，因此 `engine/streaming-send.js#sendUsageTotals` 能产出 finalize + 所累积的那三个总量，却产不出 `cs.context.limit` 需要的任何东西。于是这个上限只能像在 + acp 上一样，经由 finalize 之后的 mavis 重查询抵达。从一个 webui 批次去改 TUI 包里的 + 投影，会把 M1 那次拆分确立的依赖方向倒过来，所以这里只记录、不动手。 +7. **runtime 收不到用户在界面上选的模型。** ACP 运行器会对一个全新会话预先套用已记录的 + 模型，让引擎跑的就是那个标签所声称的模型；runtime 运行器不这么做，因为那个辅助函数 + 说的是 ACP 的 `session/set_config_option`，而 runtime 的对应物属于更后面的批次。因此 + 在 `runtime` 下，**首个**回合跑的是 runtime 自己的默认值，界面标签可能与实际不符—— + 正是那次「预先套用」本要防的缺陷，范围限定在一个会话的首个回合。这个不符是可见的 + 而不是静默的，而且在它落地之前 `runtime` 保持可选启用。 +8. **传输选择是一次环境变量读取，不是注册表查询。** `chat.js#handleSend` 里的分支把 + `MCODE_WEBUI_TRANSPORT` 与字面量 `"runtime"` 比较，而计划书写的是选择应当读 provider + 注册表。注册表归 M4 所有，而在它存在之前就硬写第二处知道 provider id 的地方，正是 + M4 要消灭的东西。本批刻意不去造一个提前到来的注册表。 + ## 6. 前端拓扑 ``` From 679d0fe410bdd60fd5101778823da92828df6cf2 Mon Sep 17 00:00:00 2001 From: acer_feng

+ +`POST /api/send` (#12) was the single endpoint whose whole behaviour +lived in one route body: it claims the turn, answers, and then runs a +turn whose output never crosses the HTTP response — it crosses the +`/api/events` SSE channel as webui chat lines (`▲` thinking, `●` answer, +`→ tool`, `##tc:` markers). B8 is the migration of that endpoint, and +it is the first batch to **light up a second transport** rather than only +re-house an existing one: after B8b, `MCODE_WEBUI_TRANSPORT=runtime` +runs a real turn, and the default `acp` path is byte-for-byte what it was +at 32277c3a — that invariance is the batch's survival condition, and +`mcode-acp.js#runMcodeAcp` and `mcode-acp.js#streamAcpPrompt` were not +edited to achieve it. + +| Endpoint | Facade function | Capability · sub-item | Enforcement | Value source | +| --- | --- | --- | --- | --- | +| `POST /api/send` (#12) | `engine/streaming-send.js#assertStreamingSendCapability` | `streamingSend` · `sendMessage` | **hard — 501** | `engine/streaming-send.js#openEngineSendStream` on the runtime transport; the acp path's source, `mcode-acp.js#streamAcpPrompt`, is deliberately **not** named by the declaration | + +The declaration itself is `engine/streaming-send.js#STREAMING_SEND_ENDPOINTS`, +a one-row table whose `subItem` is the runtime method name `sendMessage` — +the name a provider author would recognise from the source, and the name +a `partial` declaration would have to list in `missing`. Its reporting +sibling, `engine/streaming-send.js#checkStreamingSendCapability`, never +throws a capability error: a typo in webui's own endpoint key is a plain +`Error`, because caller confusion is not a capability question and the +HTTP layer must never answer 501 for a bug in this repository. + +**Why two batches for one endpoint.** B8a shipped the declaration, the +gate and the derivations as a layer with no runner and no route branch — +nothing user-visible changed and nothing called the gate, so a module +whose entire value is that it has no IO could be reviewed on its own. +B8b added the data plane at the bottom: the one place in the family that +touches the engine, plus the route's third branch. The split mattered +because the purity was provable only while it held — +`engine/streaming-send.js#openEngineSendStream` and +`engine/streaming-send.js#projectSendAttachments` are the only exports +that are not total functions over their arguments, and they are the only +reason the module now reaches for `await import()`. + +**The escape hatch still wins.** The branch in `chat.js#handleSend` is +ordered, and the ordering is load-bearing: + +| Condition | Runner | Stream source | +| --- | --- | --- | +| `MCODE_USE_ACP === "0"` | `runMcodeExec` (exec) | none — a non-streaming runner with no run-mirror | +| `MCODE_WEBUI_TRANSPORT === "runtime"` | `mcode-acp.js#runMcodeRuntime` → `mcode-acp.js#streamRuntimePrompt` | runtime frames, already projected to `TuiStreamEvent` | +| otherwise (the default `acp`) | `mcode-acp.js#runMcodeAcp` → `mcode-acp.js#streamAcpPrompt` | `mcode acp` session-update notifications | + +`MCODE_USE_ACP=0` is evaluated first because `lib/config.js` documents +the precedence as "transport=exec regardless of `MCODE_WEBUI_TRANSPORT`", +and that is the right order for the thing the variable is: the escape +hatch exists for exactly the moment a transport is misbehaving, so an +operator who reaches for it must not have to unset a second variable +first. The runtime branch passes the **same** options object the acp one +does, `owningWebuiSessionId` included, which is what makes the whole tail +below that line transport-agnostic — both runners return the same `r` and +write through the same `state-bus.js#createRunChat` buffer. + +**Why this family gates HARD, and where the gate is called.** #12's +response is `{ok:true}` written *before* the engine is called — +fire-and-forget by contract, because the output arrives on a different +channel. That is exactly what makes the gate hard, and it is the mirror +image of B7: a stop whose escalation is webui's own child management +still stops the turn, and a cancel already has a documented "I could not +do it" 200, so both have a truthful degradation. #12 has **none**. A +provider with no `streamingSend` surface cannot produce a truthful answer +to any of the three things a user would notice — the turn never runs, the +panel shows 思考中 with no stream behind it, and nothing resets the +claim. That is #110's fake success in its purest form, so +`engine/streaming-send.js#assertStreamingSendCapability` throws and +`app.js#invokeHandler` maps it to 501 with +`engine/errors.js#engineCapabilityHttpResponse`'s shared body. The route +builds nothing: no response code is added to `chat.js#handleSend` at all. + +**The gate sits before `state-bus.js#beginRun`, and that is the second +half of the argument.** The throw would otherwise land outside the `try` +whose `finally` calls `state-bus.js#endRun`, and a leaked claim refuses +every later send in that conversation with a 409 that names a turn +nobody is running. A gate that protects against a fake success by +creating a permanent fake busy is worse than no gate, so the call site +is `chat.js#handleSend`'s, at exactly one place, immediately before the +claim. + +**The gate is currently unreachable, and that is stated rather than +assumed.** `engine/streaming-send.js#providerByTransport` maps only +`runtime` to a registered provider id; the default `acp` transport has +none yet, because the registry is M4's. So under `acp` the gate answers +`unregistered-transport` and returns without throwing — the pre-M3 +behaviour, not a hole — and under `runtime` the local-runtime-v2 provider +declares `streamingSend: full`, so the answer is `checked`. The suite +pins both halves, which makes "the provider no longer declares a send +surface" a deliberate edit rather than a discovery. The table is built +per call rather than frozen at module scope, because +`engine/index.js` re-exports this module and a module-level table would +read `engine/index.js#DEFAULT_ENGINE_PROVIDER_ID` while that binding is +still in its temporal dead zone on a cold import. + +**The bridge joins two vocabularies, and it starts above the wire.** +ACP delivers an *event* vocabulary (`thought` / `message` / `tool_call` / +`tool_update` / `plan_update`) that happens to sit close to webui's line +syntax. The runtime delivers a *frame* vocabulary (SSE `dataJson` +envelopes) that webui has never consumed — but the per-turn wrapper in +`runtime-host.js` already projects those frames into structured +`TuiStreamEvent`s, so `engine/streaming-send.js` starts one level above +the wire and never sees a frame. `engine/streaming-send.js#SEND_EVENT_KINDS` +is webui's own vocabulary, not the runtime's: `thought` / `message` / +`tool` are the three families the ACP path accumulates separately, +`authoritative` is the settled message that **overwrites** the accumulator +instead of appending to it (the runtime emits deltas *and*, at close, one +complete message — the same fact `result.answer` delivers once instead of +thousands of times), `terminal` is a turn outcome, and the rest are facts +about the stream that produce no line at all. + +**The classification never throws, and that asymmetry is deliberate.** +`engine/streaming-send.js#classifySendEvent` returns +`{kind: ignore}` for a shape it does not recognise rather than killing a +turn that is otherwise streaming correctly. A bridge that throws on an +unknown frame turns every future runtime addition into an outage of the +chat endpoint, which is strictly worse than not rendering one line. + +**Four properties carry the weight, and all four are stated as shared +functions rather than re-derived per transport.** + +1. **The still-viewing test has three forms.** + `engine/streaming-send.js#sendStillViewing` is the single predicate + both runners consult, at bind time and at finalize time. Mid-turn the + user can switch conversations, which re-points `cs` at *another* + record, and a `cs` mutation after that point would stamp this turn's + engine id or title onto the session the user switched **to**. The + three forms are: no owning record id at all (a direct caller, not a + route — treat as still viewing); `cs.sessionId` equals the owning + record id (the pre-promotion form); `cs.sessionId` equals the engine + sid (the post-promotion form, because the record was renamed to the + engine id at bind time). Anything else means the user switched away, + and the turn's lines go to the owning record through + `sessions.js#promoteDraftToMcodeSid`'s sibling path instead of to the + viewed `cs.chat`. +2. **The finalize drain rewrites the last `●` line, over a detached + list.** `state-bus.js#drainRunChat` hands the route a copy of the + run's lines, and `engine/streaming-send.js#rewriteDrainedAnswerLine` + mirrors the route's in-place rewrite, which only ever runs while the + user is still viewing; the runtime path needs the same operation over + a detached array, because a turn that ended while the user was + elsewhere must still record its final answer against the run's own + lines rather than the other session's chat. Two behaviours are + load-bearing: the + **last** `●` line wins, scanning from the end, because a turn with a + tool call between two answer segments has more than one; and when + there is none the answer is **appended**, because dropping it would + lose the turn's only output on a runtime that streams no `●` at all. + The function is pure — the input array is never mutated — so a caller + can compare before and after. +3. **The draft promotion is deliberately *not* re-derived.** This is the + one red line with no predicate in the module, and its absence is the + decision. The promotion's condition — "the viewed session has an + engine id" — is already correct for both transports, because + `sessions.js#promoteDraftToMcodeSid` is itself a no-op when + `cs.sessionId === cs.mcodeSessionId`, which is the post-bind state of + every turn. Narrowing it with a second predicate would be a behaviour + change on the acp path — the survival condition — in exchange for a + guarantee the existing guard already makes. Its evidence is a route + test, not a function, and the suite pins that no such predicate exists. +4. **The 409 claim is keyed by `(cid, sessionId)`, and the runtime + branch does not change it.** `state-bus.js#beginRun` is called with + the conversation key, not `cid` alone, so a long turn in one + conversation does not refuse sends in every other conversation of the + same tab; a second send into the *same* conversation is still the + duplicate-execution guard and is still refused. The runtime runner + keeps the same three mechanics the ACP runner has: the owning webui + record is captured before the first await, the draft→engine bind goes + through the same two helpers, and the first-turn session-busy guard + is backfilled with `state-bus.js#updateRunSid` at the same instant — + because the route claimed the run before the turn existed, so on a + session's first turn the claim was registered with `sid: null` and + the engine-session guard never covered it. + +**The line grammar has exactly one home, which is why the runtime path +reuses the ACP reducer instead of writing a second one.** Tool calls go +through `mcode-acp.js#applyToolUpdate`, so the indented body syntax, the +`@ path` lines, the `! error` line and the subagent-detection wiring are +inherited by producing the same input; a second implementation would be a +second place for the `→ name` header to disagree with the body beneath +it. Two details are the runtime's own judgement and are pinned +separately. Stage mapping: `engine/streaming-send.js#sendToolUpdate` +reads the numeric +`ToolCallStatus` and maps the still-moving stages to `pending` (a body +here would print a half-streamed argument as if it were the tool's +input), `finished` to `completed` and `failed` to `error` — the ACP +path's own words. And header emission: the runtime re-sends the whole +call on every chunk of its lifecycle, so a call already announced +contributes no second `→ name`; the header for a new id is written by the +runner through `engine/streaming-send.js#sendToolHeaderLine` with its +arguments — which the reducer's synthesized header deliberately omits — +and the index is pre-registered so the reducer takes its "header already +known" branch and writes only the body. The double space in +`→ name ` is transcribed rather than tidied, because that spacing +is what the ACP line looks like and what the decoder splits on. + +**The stream is closed exactly once, and "it just stopped" is a +failure.** `mcode-acp.js#streamRuntimePrompt` is structurally the same +machine as `mcode-acp.js#streamAcpPrompt`: an accumulator `r`, a +per-event write into the run-chat buffer through +`chat-line.js#streamUpdateLine` (the same "replace the line with this +prefix, otherwise append" primitive both transports use), a bounded idle +watchdog, and a +`finalize()` guarded by a `_finalized` flag. The runtime's per-turn +wrapper converts an engine throw into an `{type:"error"}` frame rather +than a rejected iterator, so the loop never has to distinguish "the +engine crashed" from "the engine reported a crash" — and a stream that +ends with no terminal event at all is recorded as `failed`, not as +success, because treating a truncated turn as a complete one renders an +unfinished answer as a finished one. The same finalize appends the +`§§` marker lines, strips the `▍` streaming cursor, closes the per-turn +host, re-queries the mavis usage tables and reads the title back; the +title read-back and the usage re-query are the *same* calls the ACP +finalize makes, because both are already transport-aware, and duplicating +them here would be a second copy of a decision `acp-client.js` already +makes. + +**One pure function is where the "invisible" regressions live.** +`engine/streaming-send.js#sendSegmentAdvance` is the piece easiest to get +subtly wrong and the hardest to notice when it is: a missing reset makes +the next `●` line contain every previous segment's text, which still +renders and still looks like an answer. The rule matches the ACP path's +own `lastChunkKind` discriminator — a delta of the same family appends to +the buffer, a delta of a different family (or of any family after a tool +call) starts a fresh segment. The two other small mappings are pinned in +the same spirit: `engine/streaming-send.js#sendTerminalOutcome` reports +`aborted`/`interrupted` as `aborted` and **not** as a failure, because +the user pressed stop and firing an error alert for a user action is +wrong; and `engine/streaming-send.js#sendUsageTotals` returns `null` +rather than a zeroed object, because the finalize's "no usage" branch is +what falls back to a length-based estimate and a zeroed object would take +that branch away and leave the context panel reading zero tokens. + +**Boot-path weight stayed flat.** `chat.js` imports the module, so it is +on the boot path, but its static imports are `engine/capabilities.js`, +`engine/index.js` and the node builtins — all cheap. The host getter, the +per-turn host wrapper and the attachments helper are reached through +`await import()` inside `engine/streaming-send.js#openEngineSendStream` +and nowhere else, so an acp-only server never boots the runtime graph. +That is the M1 lesson, and it is what lets the module be re-exported from +the facade at all. + +**Eight things this batch records as known debt instead of deciding:** + +1. **The hard gate is declared but not exercised.** It is unreachable on + both transports today — the local-runtime-v2 provider declares + `streamingSend: full`, and `acp` has no registered provider at all — + so the honest description of the 501 is "a policy that is stated, + tested in isolation, and not yet reachable". The suite pins both + halves of that sentence, so making it reachable is a deliberate edit + rather than a surprise. +2. **`resync-required`, `messages-replaced` and `messages-rewound` are + all classified as ignored.** The runtime can tell webui that its view + of the turn diverged — that is what `resync-required` means — and + webui keeps the last rendered line buffer and says nothing to the + user. The runner's only surface is a log line, which is the right + minimum but not a resolution. Whether webui should re-derive the turn + from the engine's own spine on a resync is a product question, and it + interacts with the mirror-retirement work in `transcript.js` (#126), + where the question of which lines are authoritative is already being + re-argued. Deciding it twice, in two files, is how the two answers + drift. +3. **The bridge produces a lossy mirror, deliberately.** `●` carries a + single flattened line and `→ name` carries the call's arguments as they + were at first sighting — the same lossy form the ACP path has always + produced, and producing anything richer here would make the two + transports' transcripts incomparable. The consequence is that the + #126 mirror-retirement criterion must recognize the **runtime form** of + a lossy mirror as well as the ACP one; the two are the same fact, so + the criterion should be written once against the line grammar rather + than twice against the transports. +4. **`/api/stop` cannot stop a runtime turn, and it says so.** The + runtime runner registers no active child, because the runtime has no + subprocess for B7's kill cascade to signal, and inventing a second + interrupt protocol outside B7's family would be a worse answer than + none. A user pressing stop under the runtime transport therefore gets + B7's documented degradation: the gentle `session/cancel` refuses + (there is no ACP client), no child is registered so `hardKilled` is + false — and `engine/interrupt.js#stopLeftStaleClaim` is true, so the + route resets the thinking claim and pushes an at-rest state. The panel + recovers; the turn keeps running in the runtime. That is a truthful + "I could not stop it", and it is strictly better than the alternative, + but it is not "stopped". The fix belongs to B7's family — route + `abortSession` through the facade when the transport is `runtime`, the + way the interrupt gate already resolves the provider for that family. + Until then the runtime transport has no user-reachable abort, and that + difference between transports is a product decision about when + `runtime` becomes the default, not a refactor. +5. **Attachments reach the runtime without a MIME type.** webui's upload + pipeline (`attachments.js#resolveAttachment`) keeps `{path, name, size}` + and discards everything else, so + `engine/streaming-send.js#projectSendAttachments` sends + `application/octet-stream` — a truthful default rather than a guess, + and a real limitation, because a runtime that dispatches on MIME type + will treat an image as a file. The fix is upstream of this module (retain + the type at upload time) and changes the stored record shape, so it is + a separate change with its own compatibility question. +6. **The context limit is not bridged from the stream.** The runtime's + `TokenUsage` carries `context_window`, but the TUI projection does not + forward it, so `engine/streaming-send.js#sendUsageTotals` can produce + the three totals the finalize accumulates and nothing for + `cs.context.limit`. The limit therefore arrives, as it does on acp, + only through the post-finalize mavis re-query. Writing a projection + change in the TUI package from a webui batch would invert the + dependency direction the M1 split established, so it is recorded + rather than done. +7. **The runtime does not receive the user's model pick.** The ACP + runner pre-applies a recorded model to a brand-new session so the + engine runs the model the chip claims; the runtime runner does not, + because that helper speaks ACP's `session/set_config_option` and the + runtime's equivalent belongs to a later batch. So under `runtime` a + *first* turn runs the runtime's own default and the chip may disagree + — the exact defect the pre-apply was written to prevent, bounded to a + session's first turn. The disagreement is visible rather than silent, + and `runtime` stays opt-in until that lands. +8. **Transport selection is an env read, not a registry lookup.** The + branch in `chat.js#handleSend` compares `MCODE_WEBUI_TRANSPORT` + against the literal `"runtime"`, where the plan says selection should + read the provider registry. M4 owns the registry, and hard-coding a + second place that knows provider ids before one exists is precisely + the thing M4 exists to remove. This batch deliberately does not create + a premature registry. + ## 6.

+`engine/streaming-send.js#openEngineSendStream` 与 +`engine/streaming-send.js#projectSendAttachments` 是仅有的两个不是「对参数的全函数」 +的导出，也正是它们让这个模块不得不去用 `await import()`。 + +**逃生舱仍然优先。** `chat.js#handleSend`

+拉它的人不该还得先取消另一个变量。runtime 分支传的是与 acp 分支**同一个**选项对象， +其中就包含 `owningWebuiSessionId`——正是它让该行以下的整条尾巴都与传输无关：两个 +运行器返回同一个 `r`，并写进同一份 `state-bus.js#createRunChat` 缓冲。 + +**为什么这一族是硬门控，以及门控在哪里被调用。** #12 的应答是 `{ok:true}`， +写在调用引擎**之前**——按契约是 fire-and-forget，因为输出走的是另一条通道。这恰恰是 +它必须硬门控的原因，也正好是 B7 的镜像：一个停止请求的升级动作是 webui 自己的子进程 +管理，因此它仍然停得掉那个回合；一个取消端点本来就有一个成文的「我做不到」200。 +而 #12 **一个都没有**。一个没有 `streamingSend` 面的 provider，无法对用户会注意到的 +三件事给出任何如实答案——回合根本没跑、面板显示「思考中」而背后没有任何流、声明 +没有任何东西去重置。这就是 #110 那个假成功最纯粹的形态，所以 +`engine/streaming-send.js#assertStreamingSendCapability` 抛错，由 `app.js#invokeHandler` +映射成 501 加 `engine/errors.js#engineCapabilityHttpResponse` 那份共享响应体。路由 +自己什么都不构造：`chat.js#handleSend` 里根本没有新增任何响应码。 + +**门控位于 `state-bus.js#beginRun` 之前，而这就是论证的另一半。** 否则那一次抛出 +会落在 `try` 之外，而释放声明的 `finally`（也就是 `state-bus.js#endRun`）就在那个 +`try` 里；一个泄漏的声明会让这段对话之后每一次发送都收到 409，而那个 409 描述的是 +一个根本不存在的回合。一扇为了防止 +假成功、却制造出永久假繁忙的门，比没有门更糟，所以调用点就在 +`chat.js#handleSend` 里、只有那一处，紧挨在认领之前。 + +**这扇门当前不可达，而这一点是被陈述出来的，不是被假定的。** +`engine/streaming-send.js#providerByTransport` 只把 `runtime` 映射到一个已注册的 +provider id；默认的 `acp` 传输目前一个都没有，因为那份注册表属于 M4。所以在 `acp` +下门控回的是 `unregistered-transport` 且不抛错——那是迁移前的行为，而不是门上的洞； +而在 `runtime` 下，local-runtime-v2 provider 声明了 `streamingSend: full`，于是答案是 +`checked`。测试把这半句和那半句都钉住了，这让「provider 不再声明 send 面」成为一次 +刻意编辑而不是一次意外。这张表是每次调用现建的，而不是在模块作用域里冻结，因为 +`engine/index.js` 会再导出这个模块，而模块级表在冷导入时会在 +`engine/index.js#DEFAULT_ENGINE_PROVIDER_ID` 仍处于暂时性死区的那一刻读到它。 + +**这座桥连接的是两套词表，而它是从协议线之上起步的。** ACP 送来的是一套**事件**词表 +（`thought` / `message` / `tool_call` / `tool_update` / `plan_update`），它碰巧与 webui +的行语法相当接近。runtime 送来的是一套**帧**词表（SSE 的 `dataJson` 信封），webui 从 +未消费过它——但 `runtime-host.js` 里的逐回合包装器已经把这些帧投影成结构化的 +`TuiStreamEvent`，因此 `engine/streaming-send.js` 从协议线之上一层起步，从头到尾没见 +过帧。`engine/streaming-send.js#SEND_EVENT_KINDS` 是 webui 自己的词表，不是 runtime 的： +`thought` / `message` / `tool` 是 acp 路径分别累积的三族，`authoritative` 是那条**覆盖** +而非追加到累加器上的已落定消息（runtime 既发增量、又在收尾时发一条完整消息——与 +`result.answer` 把同一件事说一次而不是上千次是同一个事实），`terminal` 是回合结局， +其余都是关于这条流、但不产生任何行的事实。 + +**分类永不抛错，而这种不对称是刻意的。** +`engine/streaming-send.js#classifySendEvent` 对不认识的形状返回 `{kind: ignore}`， +而不是掐掉一个本来流得很好的回合。一座遇到未知帧就抛错的桥，会把 runtime 未来每 +一次新增都变成聊天端点的一次故障，那严格地比少渲染一行更糟。 + +**四条性质承着重量，而且四条都被表述为共享函数，而不是每套传输各自重新推导一遍。** + +1. **still-viewing 判定有三种形态。** + `engine/streaming-send.js#sendStillViewing` 是两个运行器在绑定时与 finalize 时都会 + 查的那一个谓词。回合进行中用户可以切换对话，那会把 `cs` 重新指向**另一条**记录， + 而此后任何一次 `cs` 改写都会把本回合的引擎 id 或标题盖到用户刚切过去的那个会话上。 + 三种形态是：根本没有归属记录 id（直接调用方而非路由——按仍在查看处理）； + `cs.sessionId` 等于归属记录 id（提升前的形态）；`cs.sessionId` 等于引擎 sid + （提升后的形态，因为记录在绑定那一刻已被改名为引擎 id）。其余情况都意味着用户切走了， + 于是本回合的行改由 `sessions.js#promoteDraftToMcodeSid` 的那条姊妹路径写进归属记录， + 而不是写进正在查看的 `cs.chat`。 +2. **finalize drain 重写末条 `●` 行，且作用在一个已分离的列表上。** + `state-bus.js#drainRunChat` 把本回合行的副本交给路由， + `engine/streaming-send.js#rewriteDrainedAnswerLine` 则镜像路由那份就地改写——后者只在 + 用户仍在查看时才会跑；runtime 路径需要在脱离的数组上做同一件事，因为一个在用户 + 去往别处时结束的回合，仍必须把它的最终答案记在**本回合自己的**行上，而不是记在另一个 + 会话的聊天里。有两条行为是承重的：**最后**一条 `●` 行获胜，从尾部往前扫，因为一个 + 在两个回答段之间插了工具调用的回合不止有一条；而当一条都没有时，答案是**追加**， + 因为丢掉它就等于在一个根本不流 `●` 的 runtime 上丢掉这个回合唯一的输出。这个函数 + 是纯的——输入数组从不被改写——因此调用方可以拿改写前后作对比。 +3. **草稿提升被刻意*不*重新推导。** 这是三条红线里唯一在模块中没有对应谓词的一条， + 而它的缺席就是那个决定。提升的条件——「正在查看的会话有引擎 id」——对两套传输 + 本来就都是正确的，因为 `sessions.js#promoteDraftToMcodeSid` 自身在 + `cs.sessionId === cs.mcodeSessionId` 时就是空操作，而那正是每个回合绑定之后的状态。 + 再用第二个谓词去收窄它，等于拿存活条件（acp 路径的行为变更）去换一个既有守卫 + 本来就已经做出的保证。它的证据是一条路由测试而不是一个函数，测试同时钉住了这里 + 不存在这样一个谓词。 +4. **409 声明以 `(cid, sessionId)` 为键，而 runtime 分支没有改动它。** + `state-bus.js#beginRun` 是拿会话键调用的，而不是只拿 `cid`，因此一个标签页里某段 + 对话中的长回合不会连带拒掉同一标签页里其他对话的发送；而对**同一段**对话的第二次 + 发送仍然是那个重复执行守卫，仍然被拒绝。runtime 运行器保留了 ACP 运行器原有的三处 + 机制：归属 webui 记录在第一个 await 之前捕获、草稿→引擎的绑定走同样那两个辅助函数、 + 首回合的会话繁忙守卫在同一时刻用 `state-bus.js#updateRunSid` 补写——因为路由在回合 + 存在之前就认领了声明，所以某个会话的首回合上，那次声明是以 `sid: null` 登记的， + 引擎会话的守卫从未覆盖到它。 + +**行语法只有一个家，这正是 runtime 路径复用 ACP 归约器、而不是另写一份的原因。** +工具调用走 `mcode-acp.js#applyToolUpdate`，于是缩进正文语法、`@ path` 行、`! error` 行 +与子代理识别接线全都被「产出同样输入」这一件事继承下来；另写一份实现，就等于多出 +一个让 `→ name` 表头与它下面正文产生分歧的地方。有两处细节属于 runtime 自己的判断， +并被单独钉住。阶段映射：`engine/streaming-send.js#sendToolUpdate` 读取数字形态的 +`ToolCallStatus`，把仍在推进的阶段映射为 `pending`（此刻产出正文，等于把半流式参数 +当成工具输入打印出来），把 `finished` 映射为 `completed`、把 `failed` 映射为 `error`—— +都是 acp 路径自己的词。表头产出：runtime 会在一次调用的整个生命周期里反复重发整个 +调用，因此一个已经宣告过的调用不会贡献第二条 `→ name`；新 id 的表头由运行器通过 +`engine/streaming-send.js#sendToolHeaderLine` 连同它的参数写出——而归约器自己合成的 +那条表头刻意不带参数——同时把索引预先登记好，好让归约器走「表头已知」那一支、只写 +正文。`→ name ` 里那个双空格是照抄而不是整理的，因为那个间距正是 acp 行的样子， +也正是解码器据以切分的东西。 + +**这条流恰好关闭一次，而「它就这么停了」是一次失败。** +`mcode-acp.js#streamRuntimePrompt` 与 `mcode-acp.js#streamAcpPrompt` 在结构上是同一台 +机器：一个累加器 `r`、通过 `chat-line.js#streamUpdateLine` 逐事件写入 run-chat 缓冲 +（两套传输共用的那个「同前缀则替换该行、否则追加」的原子操作）、一个有界的空闲 +看门狗，以及一个由 `_finalized` 标志守卫的 `finalize()`。runtime 的逐回合包装器把引擎 +抛出的一次异常转成一个 `{type:"error"}` 帧而不是一次被拒绝的迭代器，因此这个循环永远 +不必去区分「引擎崩了」和「引擎报告了一次崩溃」；而一条没有以终止事件收尾的流会被记为 +`failed` 而不是成功，因为把一个被截断的回合当成完整回合，等于把一段没写完的回答渲染 +成一段写完的。同一份 finalize 还会追加 `§§` 标记行、剥掉 `▍` 流式游标、关闭逐回合 +host、重新查询 mavis 用量表并回读标题；标题回读与用量重查与 ACP finalize 调的是 +**同样那两个调用**，因为两者都已经具备传输感知，而在这里复制一份，就是把 +`acp-client.js` 已经做过的决定再做一遍。 + +**有一处纯函数正是「不可见」回归的所在。** +`engine/streaming-send.js#sendSegmentAdvance` 是最容易悄悄弄错、而出错时最难被察觉的 +那一块：漏掉一次重置，会让下一条 `●` 行包含此前每一段的文本，而它照样渲染、照样看起来 +像一条像样的回答。这条规则与 acp 路径自己的 `lastChunkKind` 判别器一致——同族的增量 +追加到缓冲，不同族的增量（或任何出现在工具调用之后的增量）另起一段。另外两个小映射也 +以同样的方式被钉住：`engine/streaming-send.js#sendTerminalOutcome` 把 +`aborted`/`interrupted` 报成 `aborted` 而**不是**失败，因为那是用户按了停止，为一次用户 +动作弹出错误提示是错的；而 `engine/streaming-send.js#sendUsageTotals` 返回 `null` 而不是 +一个清零的对象，因为 finalize 里「没有用量」那一支才是回退到按长度估算的地方，一个 +清零对象会把那一支拿走，让上下文面板一直显示零 token。 + +**启动路径的重量保持不变。** `chat.js` 会导入这个模块，所以它在启动路径上；但它的静态 +导入只有 `engine/capabilities.js`、`engine/index.js` 与 node 内建模块——全都便宜。host +getter、逐回合 host 包装器与附件辅助函数只通过 `await import()` 在 +`engine/streaming-send.js#openEngineSendStream` 内部被触达，别处一概没有，因此一台 +纯 acp 的服务器永远不会把 runtime 那张图启动起来。这就是 M1 的教训，也正是这个模块 +之所以能够从门面上再导出的原因。 + +**本批记为已知债而不予决定的八件事：** + +1. **硬门控已被声明，但从未被触发。** 它在两套传输上都还不可达——local-runtime-v2 + provider 声明了 `streamingSend: full`，而 `acp` 根本没有已注册的 provider——因此关于 + 那个 501，诚实的描述是「一条被陈述、被隔离测试、但尚不可达的策略」。测试把这句话的 + 两半都钉住，于是让它变得可达是一次刻意编辑而不是一次意外。 +2. **`resync-required`、`messages-replaced` 与 `messages-rewound` 全都被归为忽略。** + runtime 可以告诉 webui 它对本回合的视图已经分叉——那正是 `resync-required` 的含义 + ——而 webui 保留最后一次渲染出的行缓冲，什么都不对用户说。运行器唯一的出口是一行 + 日志，那是正确的下限，但不构成一个解法。遇到 resync 时 webui 是否应当从引擎自己的 + 骨架重新推导出这个回合，是一个产品问题，而且它与 `transcript.js`（#126）里的镜像退役 + 工作相互纠缠——那里「哪些行才是权威的」这个问题已经在被重新辩论。在两个文件里各 + 决定一次，正是两个答案产生漂移的方式。 +3. **这座桥刻意产出一个有损镜像。** `●` 承载一条被压平的行，`→ name` 承载的是首次 + sighting 时那个调用的参数——正是 acp 路径一直产出的那种有损形态，而在这里产出任何 + 更丰富的东西，都会让两套传输的转录变得不可比。其后果是：#126 的镜像退役判据必须 + 同时认出有损镜像的 **runtime 形态**与 acp 形态；两者是同一个事实，所以这条判据应当 + 针对行语法只写一次，而不是针对两套传输写两次。 +4. **`/api/stop` 停不掉一个 runtime 回合，而它如实这么说。** runtime 运行器不注册任何 + 活动子进程，因为 runtime 没有子进程可供 B7 的 kill 级联去发信号，而在 B7 那一族 + 之外另造一套中断协议，比没有答案更糟。因此在 runtime 传输下按停止的用户拿到的是 B7 + 那个有文档的降级：温和的 `session/cancel` 被拒绝（没有 ACP 客户端），没有子进程被 + 注册，所以 `hardKilled` 为假——而 `engine/interrupt.js#stopLeftStaleClaim` 为真，于是 + 路由重置思考声明并推送一个静止态。面板恢复了；回合在 runtime 里继续跑。那是一句如实的 + 「我停不掉它」，严格地优于另一种选择，但它不等于「已停止」。修法属于 B7 那一族——当 + 传输是 `runtime` 时把 `abortSession` 也经由门面路由，就像中断门控已经为那一族解析 + provider 那样。在那之前 runtime 传输没有任何用户可达的中止，而两套传输之间的这个 + 差异，是关于 `runtime` 何时成为默认传输的产品决定，不是重构。 +5. **附件到达 runtime 时没有 MIME 类型。** webui 的上传流水线 + （`attachments.js#resolveAttachment`）只保留 `{path, name, size}`，其余全部丢弃，因此 + `engine/streaming-send.js#projectSendAttachments` 送出的是 + `application/octet-stream`——一个如实的默认值而不是猜测，同时也是一条真实限制：按 + MIME 类型分派的 runtime 会把图片当成文件。修法在本模块上游（在上传时留存类型），且 + 会改变已存记录的形状，因此那是另一次带自己兼容性问题的改动。 +6. **上下文上限没有从流里桥接过来。** runtime 的 `TokenUsage` 带有 `context_window`， + 但 TUI 投影没有转发它，因此 `engine/streaming-send.js#sendUsageTotals` 能产出 finalize + 所累积的那三个总量，却产不出 `cs.context.limit` 需要的任何东西。于是这个上限只能像在 + acp 上一样，经由 finalize 之后的 mavis 重查询抵达。从一个 webui 批次去改 TUI 包里的 + 投影，会把 M1 那次拆分确立的依赖方向倒过来，所以这里只记录、不动手。 +7. **runtime 收不到用户在界面上选的模型。** ACP 运行器会对一个全新会话预先套用已记录的 + 模型，让引擎跑的就是那个标签所声称的模型；runtime 运行器不这么做，因为那个辅助函数 + 说的是 ACP 的 `session/set_config_option`，而 runtime 的对应物属于更后面的批次。因此 + 在 `runtime` 下，**首个**回合跑的是 runtime 自己的默认值，界面标签可能与实际不符—— + 正是那次「预先套用」本要防的缺陷，范围限定在一个会话的首个回合。这个不符是可见的 + 而不是静默的，而且在它落地之前 `runtime` 保持可选启用。 +8. **传输选择是一次环境变量读取，不是注册表查询。** `chat.js#handleSend` 里的分支把 + `MCODE_WEBUI_TRANSPORT` 与字面量 `"runtime"` 比较，而计划书写的是选择应当读 provider + 注册表。注册表归 M4 所有，而在它存在之前就硬写第二处知道 provider id 的地方，正是 + M4 要消灭的东西。本批刻意不去造一个提前到来的注册表。 + ## 6. 前端拓扑 ``` From b5295434f83159cda90f42ccd51c59499a4b1b6f Mon Sep 17 00:00:00 2001 From: acer_feng

charset=UTF-8 Content-Transfer-Encoding: 8bit The V2 agent cutover takes a dataDir lease before `mcode acp` can serve a prompt, and the lease is a bare directory: mkdir acquires, rmdir releases, a

A process killed between the two leaves the directory behind, and an abandoned lease is then indistinguishable from a held one except by that mtime. The window was 30 minutes while the retry budget was 120 attempts at this backoff shape — about 55 seconds. A waiter could not outlast the window, so every engine launch during it spent the whole budget and then died with `agent_name_conflict_migration_failed:lock`. One killed process therefore made `mcode acp` unstartable for half an hour, and each blocked launch produced no answer, no engine process and no session — the reported send regression. The stale window drops to 2 minutes. That does not weaken the safety property: proper-lockfile derives the heartbeat from the stale window, so "two missed heartbeats before the lease is called abandoned" is unchanged, and the migration re-inspects under the lease, so the worst a wrongly-considered stale lease costs is one extra inspection rather than a double rewrite. The retry budget rises to ~195s so a waiter survives one expiry and acquires instead of dying at the moment the lease becomes reapable. Verified against the live data directory: an orphaned lease took the engine from 55450ms/exit=1 to 2030ms/exit=0, and an isolated webui instance returned a real model reply with zero `acp exited` events. --- .../agent-name-conflict-migration.ts | 35 ++++- ...agent-name-conflict-migration-lock.test.ts | 121 ++++++++++++++++++ release/public-source.json | 1 + test/vitest-suites.json | 1 + 4 files changed, 154 insertions(+), 4 deletions(-) create mode 100644 packages/local-runtime/test/unit/agent-name-conflict-migration-lock.test.ts diff --git a/packages/local-runtime/src/persistence/migration/agent-name-conflict-migration.ts b/packages/local-runtime/src/persistence/migration/agent-name-conflict-migration.ts index 7c0c73e2..734860a4 100644 --- a/packages/local-runtime/src/persistence/migration/agent-name-conflict-migration.ts +++ b/packages/local-runtime/src/persistence/migration/agent-name-conflict-migration.ts @@ -36,10 +36,37 @@ import { const MANIFEST_FILE = 'agent-name-conflicts.json'; const EMPTY_REFERENCE_COUNTS = EMPTY_AGENT_NAME_CONFLICT_REFERENCE_COUNTS; -// Synchronous backup/rewrite needs a long-lived dataDir lease. -export const AGENT_NAME_CONFLICT_MIGRATION_LOCK_STALE_MS = 30 * 60_000; -const AGENT_NAME_CONFLICT_MIGRATION_LOCK_RETRIES = { - retries: 120, +// Synchronous backup/rewrite needs a dataDir lease, so the lease outlives the +// critical section rather than the other way round. +// +// The window is 2 minutes, and it was 30.

What the **engine** receives is the wire form — `m:::u`, or `m:::v:` for a switchable builtin, plus a bare level for `thinkingEffort` and an engine vocabulary word for `permissionMode`. What **webui** records is the user-facing form — `cs.model.name` in `/`, `cs.model.thinking`, `cs.permissions` as a label. The map between them is what the suite pins, field by field, over one row per (engine option shape × request shape) in `packages/webui/test/lib/engine/model-writes.test.js`. + +**The variant channel (ticket 36) is unchanged and now covered by name.** A switchable builtin (`thinking_config.mode: switchable`, e.g. MiniMax-M3) has no engine effort vocabulary — the engine rejects every `thinkingEffort` value for it — and advertises it only as the wire pair `v:thinking` / `v:none-thinking`. Such a pick is therefore **one** `model` push carrying both the model and the on/off level, with no second push at all. Every other model keeps the two-push contract: `model` first, then `thinkingEffort`, because the engine rejects an effort set when no model is selected.

Both branches are costed in the KNOWN DEBT section of `model-writes.js` — bridge `thinkingEffort` as a third bridged id, or accept the 501 and extend the frontend's degradation to a third control. Until that is decided, #58 keeps its pre-B10 behaviour. + +**The bridge is no longer an unverified exemption.** `selectModel` and `setPermissionMode` — the two sub-items `MODE_WRITE_BRIDGED_CONFIG_IDS` names — are now in the snapshot audit's `REQUIRED_METHODS`, so a real booted host is checked for both of them on the adapter *and* the CliService surface, and a declaration that stops listing one goes red.

The change is one +// `assertEngineCapability(...)` call before the push. +// +// - #58 /api/set-model ALSO writes `thinkingEffort`, and +// `thinkingEffort` is a GENERIC config id — the one the plan +// (§3a, row 68) says has nowhere to be delivered under a +// provider with no generic write. Gating #58 the same way makes +// the thinking-effort control answer 501 for the same reason #68 +// does for an unrecognised id. +// +// Two branches, both costed, neither chosen here: +// +// (a) BRIDGE `thinkingEffort` as a THIRD id in +// `MODE_WRITE_BRIDGED_CONFIG_IDS`, pointed at a sub-item that +// means "the dedicated thinking-effort writer". Cost: a third +// name in a table the frontend mirrors, and a third declaration +// the snapshot audit must then prove exists on both surfaces +// (today's probe found no `setThinkingEffort` / +// `selectThinkingEffort` on either, so the name would have to +// be agreed with the engine team first). Benefit: #58 becomes +// gateable on the same table as #59, and the two controls stay +// symmetric. +// +// (b) ACCEPT the 501 and degrade the UI. Cost: the thinking-effort +// control disappears for any provider that denies the generic +// config write — which, under M4's ACP provider, is most of +// them — and `#58` loses a working half to keep an enrichment. +// `webapp/lib/engine-capabilities.ts` would need a third +// bridged id for the effort control to follow the same +// fail-open rule rather than a 501 at click time. +// +// Until a human picks one, #58 keeps its pre-B10 behaviour, and this +// module stays gate-ready: the push is already a single call site per +// endpoint, so arming either gate is one line in the executor. +// +// 2. B9's KNOWN DEBT 2 (the bridge naming sub-items no audited host was +// proven to have) IS CLOSED BY THIS BATCH, and the evidence is in +// `test/lib/engine/capability-snapshot.test.js`: `selectModel` and +// `setPermissionMode` are now in `REQUIRED_METHODS`, so the audit +// asserts they are functions on BOTH the adapter and the cliService +// surface of a real booted host.

On the variant +channel an unchanged recorded level is still carried by the model push, so an +absent `thinking` field falls back to the recorded value. On the effort channel +a level is carried only when the request carried one — an absent field means +"leave the recorded effort alone", and there is no wire form here that could +carry it without also re-selecting the model.

It is recorded and nothing consumes it today, because the engine has no +context-window channel; it was stamped before this batch and stays stamped. + +**The mirror rule is half in the facade and half in the route, and the split is +B9's.** `engine/model-writes.js#applyThinkingEffortMirror` owns the *rule* — +after an accepted effort push the local snapshot should claim the engine's new +value; after a cleared pick it should claim none — and returns how many options +it touched, which is what makes "no `thinkingEffort` option in the snapshot yet" +observable instead of a silent no-op. The *write* stays in the route, because +`cs.configOptions` is webui's own view and is mutated in place exactly as before, +on exactly the same conditions.

The clear also does not depend on the model push having succeeded, which +is pre-existing behaviour and is preserved as-is rather than tidied up. + +**Three things this batch records as known debt instead of deciding:** + +1. **Neither endpoint is gated, and that is a decision left open for a human.** + B9's gate already exempts exactly the two config ids these endpoints write — + `model` → `selectModel`, `permissionMode` → `setPermissionMode`, the table in + `engine/mode-writes.js#MODE_WRITE_BRIDGED_CONFIG_IDS` — so both sub-items are known + names and neither needs rediscovering. What stops the gate from being armed + here is one more config id, and it is #58's: + + | Branch | Cost | Benefit | + | --- | --- | --- | + | **(a) bridge** `thinkingEffort` as a third id in `MODE_WRITE_BRIDGED_CONFIG_IDS`, pointed at a sub-item meaning "the dedicated thinking-effort writer" | a third name in a table the frontend mirrors, and a third declaration the snapshot audit must then prove exists on both surfaces — today's probe found no `setThinkingEffort` / `selectThinkingEffort` on either, so the name has to be agreed with the engine team first | #58 becomes gateable on the same table as #59, and the two controls stay symmetric | + | **(b) accept** the 501 and degrade the UI | the thinking-effort control disappears for every provider that denies the generic config write — under M4's ACP provider, most of them — and #58 loses a working half to keep an enrichment; `engine-capabilities.ts` would need a third bridged id for the control to follow the same fail-open rule | the capability declaration stops being a lie about a control that still works | + + `thinkingEffort` is a **generic** config id — the one the plan (§3a, row 68) + says has nowhere to be delivered under a provider with no generic write — so + gating #58 the way #59 could be gated makes the thinking-effort control answer + 501 for the same reason #68 does for an unrecognised id. Until a human picks + a branch, #58 keeps its pre-B10 behaviour. **#59 alone is the zero-risk half:** + gating it hard on `engine/capabilities.js#assertEngineCapability` is behaviourally + inert today (no registered provider lists that sub-item as missing, and the + snapshot audit proves both providers really have the method) and is safe + against the shipped UI, which already hides the permission selector under + exactly that declaration (`webapp/lib/engine-capabilities.ts` + + `webapp/components/composer.tsx`). It is still not taken here, because taking + it would be making a product decision by capability table, with no changelog + and no frontend work — the same argument B7 recorded for #71. The module is + gate-ready either way: the push is one call site per endpoint, so arming + either gate is one line. +2. **`contextWindow` is recorded and never pushed.** The engine's ACP surface has + no channel for it — `session/set_config_option` accepts exactly three config + ids and the model wire encoding has no context segment — so the pick is a + webui-side preference the picker reflects immediately. Pre-existing, unchanged + here, and listed because this batch is the one that owns the whole #58 write: + a reader of the facade should not assume the whole request reaches the + engine. Wiring it is engine-side work, and the seam is the output of + `engine/model-writes.js#planModelSelectionPush`, which a future engine + channel would extend with a third push. +3. **B9's bridge-naming debt is closed by this batch, and the record is the + snapshot audit.** `selectModel` and `setPermissionMode` are now in + `REQUIRED_METHODS`, so + `test/lib/engine/capability-snapshot.test.js#auditProviderCapabilities` + asserts they are functions on both the adapter and the cliService surface of + a real booted host. They were verified present before being added. + `engine/mode-writes.js` is a read-only reference in this batch, so its own + debt text is left exactly as written; this entry is the closure record. ## 6.

产品决定——这正是 B7 为 #71 记下的同一条理由。无论如何这个模块已是挂门就绪的： + 每个端点的推送都只有一个调用点，所以打开任何一个门都是一行的事。 +2. **`contextWindow` 只记录、从不推送。** 引擎的 ACP 面上没有它的通道—— + `session/set_config_option` 只接受三个 config id，而模型 wire 编码里没有上下文 + 段——所以这个选择是一个 webui 侧偏好，选择器会立即反映它。这是既有行为，本批 + 未改；之所以列出来，是因为本批是拥有整个 #58 写侧的那一批：读门面的人不应假定 + 整个请求都抵达了引擎。接线是引擎侧的工作，而那道缝就是 + `engine/model-writes.js#planModelSelectionPush` 的输出——将来的引擎通道会以第三次 + 推送扩展它。 +3.

Its resolved value becomes the JSON-RPC `result`; a throw or rejection becomes an error response carrying the thrown `message` and, when it has one, its `code` (otherwise `-32603`). Nothing in the webui installs a handler yet — routing a decision through to the browser is separate work, and the honest current state is that the webui has no interactive surface to offer. +### Engine stderr in the crash alert + +The engine announces its own failures on stderr and then dies; the crash alert is raised by the webui, not by the engine. `McodeAcpClient` therefore keeps a bounded tail of that stream — the last 2KB and the last 20 lines, cleared at every `start()` so one process's crash text can never be blamed on the next — and the `[mcode-acp.start]` and `[mcode-acp.stream]` error alerts carry it as `data.stderrTail`, prefixed with `[acp stderr truncated, showing the tail]` when anything was dropped.

A silent engine leaves `data` byte-identical to what it was before the field existed, so no consumer of the alert contract has to learn a new required key. The `debug` constructor option keeps its old job — mirroring the stream live to the server's own stderr as it arrives — but all three construction sites in the shipped server pass `debug: false`, so in a running webui the alert's tail is the only channel that stderr has. + ### What this does and does not buy `plan: {}` turns on a **notification**, not a question. A plan review carries a single `approve` option and the Runtime pins `allowOther: true` on every step, so the engine settles it fail-closed through the questionnaire path rather than turning it into a permission request — which is why advertising `plan` is safe for a client that cannot answer anything. The permission-request path is a separate switch the webui never turns on. diff --git a/docs/webui.zh-CN.md b/docs/webui.zh-CN.md index 1f6af167..59d3d70f 100644 --- a/docs/webui.zh-CN.md +++ b/docs/webui.zh-CN.md @@ -324,6 +324,12 @@ ACP 握手是双向的，两个方向都由同一份 `initialize` 载荷决定 留给真实交互界面的接缝是构造函数选项 `clientRequest`：`(method, params) => result | Promise`。它的 resolved 值成为 JSON-RPC 的 `result`；抛错或 reject 变成错误响应，携带抛出的 `message` 与（若有）`code`，否则为 `-32603`。webui 目前没有安装任何处理器——把一次决定真正送到浏览器是另一件事，诚实的现状是 webui 没有可提供的交互界面。 +### 崩溃告警里的引擎 stderr + +引擎把自己的失败写在 stderr 上然后死掉，而崩溃告警是 webui 发的，不是引擎发的。所以 `McodeAcpClient` 会留住这段输出的一个**有界尾部**——最后 2KB 且最后 20 行，并且在每次 `start()` 时清空，免得一个进程的崩溃信息被算到下一个进程头上——`[mcode-acp.start]` 与 `[mcode-acp.stream]` 这两条错误告警把它作为 `data.stderrTail` 带出去；若确实丢掉了内容，前面会加上 `[acp stderr truncated, showing the tail]`。退出码不是诊断：`mcode acp exited (code=1)` 分不清是引擎拿不到锁，还是配置被它拒绝解析；引擎自己那一行（`agent_name_conflict_migration_failed:lock`）才能说明是哪一种。 + +`stderrTail` 是新增的可选字段。引擎若什么都没写，`data` 与这个字段出现之前逐字节相同，所以告警契约的任何消费方都不必学到一个新的必填键。`debug` 构造选项保留它原来的职责——把这段流实时镜像到服务端自己的 stderr——但要清楚：已发布服务端的三个构造点全部传 `debug: false`，因此在一个真正跑起来的 webui 里，告警里的尾部是 stderr 唯一的出口。 + ### 这次拿到了什么、没拿到什么 `plan: {}` 打开的是**通知**，不是提问。计划评审只有一个 `approve` 选项，而运行时把 `allowOther: true` 固定在每一步上，所以引擎会走问卷通道 fail-closed 地了结它，而不会把它变成一次权限请求——这正是「声明 `plan`」对一个什么都答不了的客户端仍然安全的原因。权限请求通道是另一个开关，webui 从不打开它。 diff --git a/packages/webui/acp.mjs b/packages/webui/acp.mjs index d20fe273..94197581 100644 --- a/packages/webui/acp.mjs +++ b/packages/webui/acp.mjs @@ -34,6 +34,20 @@ const DEFAULT_CWD = process.cwd() const JSON_RPC_METHOD_NOT_FOUND = -32601 const JSON_RPC_INTERNAL_ERROR = -32603 +// Bounded tail of the engine subprocess's stderr. +// +// The engine reports its OWN failures on stderr — a failed migration, a +// lock it could not take, a config it refused to parse — and the crash +// alert is raised by the webui, not by the engine.

Wh **The bridge is no longer an unverified exemption.** `selectModel` and `setPermissionMode` — the two sub-items `MODE_WRITE_BRIDGED_CONFIG_IDS` names — are now in the snapshot audit's `REQUIRED_METHODS`, so a real booted host is checked for both of them on the adapter *and* the CliService surface, and a declaration that stops listing one goes red. Neither surface carries a `setThinkingEffort` / `selectThinkingEffort`, which is the fact the gating decision above turns on. +### M3-B11: the provider family moves behind the facade, and the two provider files become one (storage change) + +`GET /api/providers` (#62), `PUT /api/providers` (#63), `POST /api/providers/test` (#64), `GET /api/providers/presets` (#65) and `POST /api/providers/preset/:id/enable` (#66) are the last catalogue family in the migration, and the only one that changes where a user's data lives. + +**What changed.** webui kept two files describing the same providers: `~/.mcode-webui/providers.json` (the v2 catalogue, ordered, lossless) and the engine's `/config.yaml` `custom_provider` tree (a projection of the first, written by a double-write that had no transaction across it). The projection was lossy and the loss was invisible precisely because nothing read it back: a disabled provider, a `coding-plan` provider, a `preset` name and the gemini-vs-openai protocol distinction all vanished on the way to the engine, and the catalogue's ordering came from the file that was about to stop being authoritative. There is now one file. Each webui-managed entry carries its webui record beside its engine fields: + +```yaml +custom_provider: + acme-gateway: + name: Acme Gateway + kind: custom + api: openai-completions + options: { apiKey: …, baseURL: …, authMode: api-key } + models: { glm-5.3: { limit: { context: 128000 } } } + _webui_owned: true # ownership: webui wrote this entry + _webui_provider: { … } # the authoritative v2 record, verbatim +``` + +Both marker fields are ignored by the engine, which parses `config.yaml` through js-yaml with no schema rejection and reads named fields. A provider the engine cannot express still gets its key, its marker and its record — it simply has no engine fields, which is the whole difference from the double write. + +**The migration, and the fallback.** While the store carries no `_webui_provider_migration` marker, the deprecated `providers.json` is still the authority; webui folds it into the store on the next read and stamps the marker on success, after which the file is never read again. A migration that fails — an unparseable `config.yaml`, a write that could not complete — leaves the store byte-identical and the old format readable, and the next read retries. The marker is a field rather than an inference ("the tree has webui entries") for one concrete reason: an operator who deletes every provider leaves a tree with no webui entries, and an inferred marker would hand authority back to the stale file and resurrect what they had just removed. + +Field-by-field equivalence and both fallback paths are pinned in `packages/webui/test/lib/engine/provider-migration.test.js`, on a fixture built to break every assumption the migration could be quietly making: several providers, every schema field, and the boundary values (empty label, absent `preset`, disabled, `coding-plan`, the gemini protocol, a zero context limit, empty thinking levels, a model id the engine key grammar rejects, unicode, a 4096-character key). + +**PUT atomicity is now structural.** There is one file and one `rename`, so the two-file disagreement the old arrangement allowed — the catalogue committed, the engine projection failed, a 200 with a warning nobody had to read — cannot be constructed. A refused write (an unparseable `config.yaml` is refused, never overwritten, because rewriting it would destroy every engine setting the store does not own) or a failed write leaves the previous document intact, and a concurrent reader always sees a whole catalogue. + +**The gates.** The two write endpoints declare `authCredentials` and gate **hard** on `updateUserModelProvider` / `createUserModelProvider`: the catalogue the operator is about to see is read by the engine, so a provider that cannot write providers cannot truthfully answer 200. The three read endpoints declare the same capability and gate **soft** — a provider with no provider surface still serves a well-defined catalogue, so hard-gating them would delete a working UI over an enrichment. As in B9, an unregistered transport (`acp`, until M4) is not a 501. + +**What a client observes.** The endpoint shapes, statuses, masking rule, keep-key convention, probe semantics and the `providers.updated` SSE frame are unchanged. Two response *values* moved with the storage: `PUT`'s `path` is now the engine's `config.yaml`, and it also reports `engineSync: {ok, written, keys}` for the store write itself. `GET`'s `sources` and `userPath` are unchanged in both field and value — they still name the deprecated file, because "which files did the server resolve" is a question an operator asks when a provider is missing, and the answer is now carried by the bilingual docs rather than by a renamed field. + +**Three decisions are recorded rather than taken.** `POST /api/providers/test` names `testUserModelProvider` in its gate, and that method cannot answer it: the engine's tester is keyed on a *persisted* provider, while the endpoint tests an unsaved candidate from a form. The probe stays webui-local, which is also the only option that keeps its two load-bearing properties (the local key-format check runs before any network call, and the apiKey goes to the configured baseURL and nowhere else). The preset gallery is still webui's own template list, and the engine has a different one; the two are not the same taxonomy, so the plan's "align the two template sets" is made visible rather than closed. And a webui provider whose engine key collides with an operator's hand-written entry still overwrites it, because the key *is* the runtime id and a silent rename would turn a recorded model pick into an unresolvable one. All three are costed in the KNOWN DEBT sections of `provider-reads.js` and `provider-writes.js`. + ### Migration state and constraints - **M1 done in this batch**: host construction (`createCatalogueHost`) moved verbatim into `server/engine/providers/local-runtime-v2.js`; `runtime-host.js` re-exports it, so every existing importer is untouched.

The product never resolved a provider path beyond what its resolver returned: `sources.cwd` is `join(process.cwd(), "models.json")`, and `process.cwd()` is `getcwd(2)`, which returns a fully-resolved path on every POSIX platform. The assertion built its expectation from the literal string the test had chdir'd into, so the two agreed only when the temp path had no symlink component — true on Linux CI, false on macOS, where `/var` is a symlink to `private/var`. Normalising the EXPECTED side is the fix, and the behaviour is now pinned rather than assumed: - the assertion states the contract (`process.cwd()` + the file name) instead of re-deriving it; - a named regression test drives a real symlinked cwd and asserts webui applies no second resolution of its own; - the same symlink machinery is applied to the WRITE path, where the question is a security one: the store is 0600 via tmp+rename and carries every plaintext apiKey, so a write that resolved its path differently from the read would put the keys in a file the catalogue never reads; - a source tripwire fails if a `realpath` (or equivalent) is ever added to the provider path resolution, so the symptom is not "fixed" in product code next time. Both the symlink behaviour and the tripwire were verified to bite: a `realpathSync` injected into `loadProvidersConfig` turns the symlink test, the sources test and the tripwire red. The whole B11 suite was re-run with TMPDIR pointed at a symlinked directory, which reproduces the macOS `/var` condition on Linux: 149 tests pass. The pre-fix assertion fails under exactly that condition and the post-fix one passes.

That is the whole closure mechanism, and it is deliberately one-directional: the engine shipping a dedicated effort writer is an event nobody here can schedule, and the audit is what makes it impossible to miss. When it happens, the name moves from `unimplemented` to `methods`, the declaration is re-audited, and the control comes back on its own. + +What is deliberately **not** done: no provider's `authCredentials` declaration was edited to list `setThinkingEffort` in `missing`.

Promoting `interrupt` to +`full` on the strength of "the protocol has a cancel" makes the audit +red, with that reason attached. + +Two places where the acp column is *stronger* than the runtime one, and +where flattening it would be the unearned claim the matrix forbids: the +protocol registers `session/set_mode` as a real request (so +`toolSkillInvocation` does **not** miss `setMode` here, unlike both +runtime surfaces), and `session/set_config_option` dispatches the +`model` and `permissionMode` config ids, so two of the three bridged +writers of `MODE_WRITE_BRIDGED_CONFIG_IDS` are genuinely reachable over +acp. + Boot-path discipline: `app.js` reaches `engine/index.js`, so that file and everything it imports statically must stay free of `@mavis/*`, `@minimax/*` and the host modules.

+//
+// Why a layout tripwire and not a screenshot: the defect is a CSS box-model

+// markdown-code-wrap tripwire documents). So the test states the invariant
+// explicitly and evaluates the shipped cascade against it:

+//       code.codeblock-code scroll box → must absorb the overflow
+//
+// The chain only holds if the `

- * the masking contract; the user clears the field to overwrite (the

- *
- * The add-model dialog (ticket 54) is a different contract and DOES
- * ship the eye toggle (desktop parity): there is no stored key and
- * no masked placeholder — the field's value is exactly what the user
- * just typed, so revealing it leaks nothing the user cannot already

+| Editing runs through the same dialog | A click on a list row opens the **same** modal (`editTarget`), seeded by `editSeedFromDraft`: a preset provider lands on its own catalogue branch, a custom one on 「+ 其他（自定义）」. Id, display name, auth type, 接口地址, the custom headers and the model entries all arrive pre-filled. The title switches from 添加模型 to 编辑模型 (`providers.dialog.editTitle`). Two entry points share one form rather than two forms free to drift |
+| The commit starts from the stored record | The committed draft begins at the record being edited (`const base = editTarget ?? newDraftProvider()`); only the fields the form can reach are taken from form state. `enabled`, `preset` and `draftId` are properties of the **record**, not the form — rebuilding one would re-enable a provider the operator had disabled, or detach it from its preset. The panel locates and replaces the row by `draftId`, not by wire id: matching on the id would write a second record instead of renaming the first whenever a custom id is retyped |
+| The key still never lands on disk in edit mode | The edit seed's API Key is always `""`, the server's keep-the-existing-key sentinel; the masked value reaches the placeholder only and is never written back as a value. An untouched field preserves the stored credential; a typed one replaces it |

Delete did not disappear with them: it moved onto the list row as 🗑 (`provider-delete-{draftId}`, `Popconfirm` confirmation). Preset rows still carry no delete, the retired editor's own rule — a preset's lifecycle belongs to the preset controls |
