From 690ade90a772bccb26b79e4063c4e8266b9020e9 Mon Sep 17 00:00:00 2001 From: Piotr Laczkowski Date: Thu, 27 Aug 2026 16:08:45 +0200 Subject: [PATCH 1/5] feat(engine): executable acceptance, budget classes, model ladder, isolation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Five capabilities adapted from the-open-engine/zeroshot's executor–verifier orchestration, rewritten for this harness's thesis: small local models, a fixed runway, and gates that fail closed. Nothing is vendored — zeroshot is TS/Rust and this is Go, so what carries over is the topology, not the code. Its central claim (an independent LLM verifier) is deliberately NOT adopted: our gates ask the filesystem, which is strictly stronger evidence than a second opinion from the same weak model. ── Executable acceptance criteria ──────────────────────────────────────────── plan.Task.Acceptance is prose, and pkg/quality has always mined it for runnable commands with a whitelist scan. That loses three things: WHICH condition failed, whether a condition is blocking, and whether it was checked at all. plan.Criterion{ID, Text, Verify, Priority} carries all three. quality. VerifyCriteria runs each Verify through the same whitelist and sanitizer every auto-run command already passes — a criterion cannot widen shell scope by one character — and reports three verdicts, never two: PASSED a command ran here and exited 0 FAILED it ran and did not; a failed `must` fails the task UNVERIFIED nothing ran — no command, or one the whitelist refused The third state is the point. The prose scan's silent third state is exactly how "the harness did not check" becomes "the harness says it is fine". UNVERIFIED never blocks, but it denies the reviewer fast path: disk evidence proves the worker CHANGED something, never that the stated condition is now true. Acceptance stays the compatibility surface — Normalize synthesizes it from Criteria — so every consumer that predates the field is untouched, and a model too small to emit criteria still produces a valid task. ── Budget classes ──────────────────────────────────────────────────────────── The composer already chose phases, team and skills; it never chose how much of the run's budget a request is worth, so "rename a variable" could still walk architect → explore → plan → split → execute → review → test. On a 7-32B model that ceremony IS the failure: the runway is gone before the edit lands. complexity (trivial|simple|standard|critical) × kind (inquiry|task|debug) buys a Profile: optional phase breadth, wave budget, think passes, QA rounds, strict reviewer. What it explicitly does NOT scale is reviewer COUNT — our reviewers are LLM calls and our gates are not, so a higher class buys more determinism, never more voices. composer.Classify is a deterministic cheap tier that costs nothing and answers the easy majority; it reports Confident only on a strong signal, and only trivial/inquiry skip the composer LLM entirely. Critical still pays for it: "confidently classified" is not "easy", and a change to auth or billing is exactly where a model's judgment about specialists is worth its tokens. Config is a ceiling for boolean gates — a class may switch one off, never on. The single downgrade is RequireSmoke for a read-only inquiry, which writes nothing and so could never satisfy it: a deadlock, not a safeguard. ── Role→model map and failure escalation ───────────────────────────────────── The whole routing story was FastModel plus an isLightAgent classification: one lever, two models. model_roles generalizes it to as many models as an operator names. model_escalation answers a different question — this TASK keeps failing — using state Task.AttemptLog was already recording and nothing read back. A rung is a separately registered agent, identical to its base except the model it is pinned to, so escalation stays out of the hot path and a task that never escalates pays nothing. Every id-classification helper goes through BaseRoleID: an escalated worker that stopped matching isCodingRole would keep running with the wrong token budget, invisibly. ── Worktree isolation ──────────────────────────────────────────────────────── pkg/rewind already snapshots and restores per wave. Two things it cannot do: abandon (one operation that cannot half-succeed, covering files nothing predicted) and contain (an out-of-scope write lands somewhere the operator was never using). The seam is one line: point Config.Root at a throwaway git worktree. Every ws_* tool already resolves against it, so the tool layer is isolated without knowing. Config.StateDir pins .slmcode to the ORIGIN — derived from a throwaway worktree, the memory layers, repair rules and bandit policy would be thrown away with it, turning "it gets better at your repo" into "it starts from zero every run". In-place stays the default permanently: plenty of workspaces are not git repos. ── Issue intake and pull-request delivery ──────────────────────────────────── `gh` rather than a Go client: already installed, already authenticated, no new token to store or leak. An issue body is untrusted internet text that becomes the run query, so it is framed as a report rather than pasted as instructions, its harness markers are defused, and it is truncated so a long issue cannot evict the repo map from the pack. Delivery is the one thing here that leaves the machine, so it takes a flag AND a confirmation showing branch, title and the exact file list; with no TTY it refuses unless --yes. Only files the run's completed tasks named are staged, never `git add -A`. ── Bugs found by running it ────────────────────────────────────────────────── - Isolation did not isolate: openHarness builds the orchestrator, and its workspace, from the original root before Config.Root is redirected. A live run edited main.go in the origin. The orchestrator is now rebuilt after. - Interrupting an isolated run leaked the worktree and its branch: teardown was inline past six `return failf(...)` paths. Now deferred. - vcs.BranchName("!!!") produced "slmcode/", which branchSafe accepts (slash is legal) and git then rejects — a cosmetic input failing at the last step. - The classifier missed inflected forms: "panics" did not match "panic". - The review-time criteria insurance ran for roles the worker path skips, so a tester task executed the project's suite twice, once per path, where the per-report command cache could not see the duplication. --- cmd/slmcode/cmd_compose.go | 32 ++ cmd/slmcode/cmd_core.go | 49 ++- cmd/slmcode/cmd_deliver.go | 253 ++++++++++++++ cmd/slmcode/cmd_isolate.go | 173 ++++++++++ pkg/agents/decoding_test.go | 5 + pkg/agents/escalate.go | 228 +++++++++++++ pkg/agents/escalate_test.go | 279 +++++++++++++++ pkg/agents/factory.go | 38 ++- pkg/agents/prompts.go | 28 +- pkg/composer/composer.go | 36 ++ pkg/composer/profiles.go | 475 ++++++++++++++++++++++++++ pkg/composer/profiles_test.go | 367 ++++++++++++++++++++ pkg/config/config.go | 52 ++- pkg/evolve/bandit.go | 13 + pkg/loop/criteria_gate_test.go | 126 +++++++ pkg/loop/critique.go | 86 ++++- pkg/loop/escalate.go | 147 ++++++++ pkg/loop/escalate_test.go | 223 ++++++++++++ pkg/loop/runner.go | 97 +++++- pkg/orchestrator/budget_class_test.go | 199 +++++++++++ pkg/orchestrator/composer.go | 142 +++++++- pkg/orchestrator/langpick.go | 103 ++++++ pkg/orchestrator/langpick_test.go | 92 +++++ pkg/orchestrator/orchestrator.go | 10 + pkg/orchestrator/runner.go | 20 ++ pkg/plan/criteria.go | 197 +++++++++++ pkg/plan/criteria_test.go | 249 ++++++++++++++ pkg/plan/kanban.go | 9 + pkg/plan/tasks.go | 35 +- pkg/quality/criteria.go | 327 ++++++++++++++++++ pkg/quality/criteria_test.go | 437 ++++++++++++++++++++++++ pkg/quality/sections.go | 10 +- pkg/sandbox/sandbox.go | 309 +++++++++++++++++ pkg/sandbox/sandbox_test.go | 431 +++++++++++++++++++++++ pkg/sandbox/statedir_test.go | 113 ++++++ pkg/schema/schema_test.go | 5 +- pkg/schema/spec.go | 22 +- pkg/vcs/issue.go | 211 ++++++++++++ pkg/vcs/pr.go | 255 ++++++++++++++ pkg/vcs/vcs_test.go | 287 ++++++++++++++++ 40 files changed, 6120 insertions(+), 50 deletions(-) create mode 100644 cmd/slmcode/cmd_deliver.go create mode 100644 cmd/slmcode/cmd_isolate.go create mode 100644 pkg/agents/escalate.go create mode 100644 pkg/agents/escalate_test.go create mode 100644 pkg/composer/profiles.go create mode 100644 pkg/composer/profiles_test.go create mode 100644 pkg/loop/criteria_gate_test.go create mode 100644 pkg/loop/escalate.go create mode 100644 pkg/loop/escalate_test.go create mode 100644 pkg/orchestrator/budget_class_test.go create mode 100644 pkg/orchestrator/langpick.go create mode 100644 pkg/orchestrator/langpick_test.go create mode 100644 pkg/plan/criteria.go create mode 100644 pkg/plan/criteria_test.go create mode 100644 pkg/quality/criteria.go create mode 100644 pkg/quality/criteria_test.go create mode 100644 pkg/sandbox/sandbox.go create mode 100644 pkg/sandbox/sandbox_test.go create mode 100644 pkg/sandbox/statedir_test.go create mode 100644 pkg/vcs/issue.go create mode 100644 pkg/vcs/pr.go create mode 100644 pkg/vcs/vcs_test.go diff --git a/cmd/slmcode/cmd_compose.go b/cmd/slmcode/cmd_compose.go index 18cab13..2682bcc 100644 --- a/cmd/slmcode/cmd_compose.go +++ b/cmd/slmcode/cmd_compose.go @@ -80,6 +80,29 @@ func readLatestComposition(slmDir string) (composer.Composition, error) { return comp, nil } +// plural renders "1 wave" / "3 waves".

With no ladder configured EscalationRungs +// is zero and every function here returns the base role unchanged. +// - it never dispatches to an id that is not registered. HasRole is checked +// every time, because an unregistered agent id is not a degraded run — it +// is a hard task failure, and it would happen precisely on the tasks that +// were already struggling. +// - it is monotone in attempts, so it cannot oscillate between models while +// a task is being retried. + +// DefaultEscalateAfter is how many recorded failures a task takes before it +// steps up a rung. +// +// Two, not one. A single failure is the common case for work that then +// succeeds on the retry — the corrector was given a specific issue and fixed +// it — and escalating there would spend the big model on nearly every task in +// a run.

6d9fe8c6b6b2bc15978fd68b37c3644ee9666528 Mon Sep 17 00:00:00 2001 From: Piotr Laczkowski Date: Thu, 27 Aug 2026 16:09:10 +0200 Subject: [PATCH 2/5] feat(studio): rebuild the Live page around the stream it exists to show MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Supersedes the collapsible-panels approach: same complaint, structural fix rather than a cap. The page is now four fixed zones in priority order, and the ordering IS the design. 1. Command bar what you type and the button you press. One row on desktop, wraps below. Never scrolls away. 2. Phase rail where the run is, in ~44px. 3. Run setup how it is configured, behind a disclosure. 4. Stream + rail everything left over, which is most of the screen. ── PhaseRail ──────────────────────────────────────────────────────────────── One horizontal track replaces four separate header panels — a metrics grid, a percentage bar, a wrapped grid of phase chips and a "current stage" card — that between them spent roughly a third of the viewport answering one question. It answers it better too: position along the rail IS the progress bar, so the two cannot disagree. The active phase scrolls itself into view. Colour carries meaning and nothing else. Phases were tinted from a fifteen-entry per-phase palette, which reads as decoration because it is — nobody holds fifteen hues to fifteen phase names. The tint is now the phase's GROUP (five, and groups are a real concept in pipeline.yaml); STATE is carried by fill and weight. ── RunSetup ───────────────────────────────────────────────────────────────── Composition, team, handoff and SLM-fit hints are genuinely useful, and useful at a different moment than the log: you read them while deciding what to run and stop the instant the run starts. Three disclosure states, not two: preview collapsed — a deterministic GUESS from the query text running collapsed — you are watching the log runtime, finished open — this is what actually ran A composition-read error renders OUTSIDE the disclosure. Hiding it behind a collapsed panel means the one state the user must act on is the one they cannot see. ── Screen adaptability ────────────────────────────────────────────────────── The rail is a column at ≥1024px and a full-height overlay below it, seeded from the breakpoint and reset when the viewport crosses it — an overlay defaulting to open covered the console the user came for. The nav sidebar now forces its icon rail below `lg`: at 224px wide it took 60% of a 375px screen, leaving the page it navigates to to fight for the rest. The user's own collapse preference is preserved, not overwritten, and applies again when there is room. LiveFeedback gains a compact mode and docks to the bottom of the stream, where a reply belongs — next to what you are replying to, not in a header card above it. ── The preview was presenting a guess as a decision ───────────────────────── Reported: typing a query instantly produced a full "Planned pipeline" panel, and for a Go repository it named python-worker and python-tester. It is now labelled "Provisional pipeline · guess", collapsed, and says plainly that the composer agent picks the real phases when the run starts. The wrong team itself is fixed in the engine (see langpick.go). --- web/src/components/Live/LiveFeedback.tsx | 45 +- web/src/components/Live/LiveView.tsx | 1284 +++++++------------- web/src/components/Live/PhaseRail.test.tsx | 116 ++ web/src/components/Live/PhaseRail.tsx | 144 +++ web/src/components/Live/RunSetup.test.tsx | 164 +++ web/src/components/Live/RunSetup.tsx | 260 ++++ web/src/components/Sidebar.tsx | 55 +- web/src/hooks/useMediaQuery.ts | 43 + web/src/types/index.ts | 5 + 9 files changed, 1234 insertions(+), 882 deletions(-) create mode 100644 web/src/components/Live/PhaseRail.test.tsx create mode 100644 web/src/components/Live/PhaseRail.tsx create mode 100644 web/src/components/Live/RunSetup.test.tsx create mode 100644 web/src/components/Live/RunSetup.tsx create mode 100644 web/src/hooks/useMediaQuery.ts diff --git a/web/src/components/Live/LiveFeedback.tsx b/web/src/components/Live/LiveFeedback.tsx index c396944..e81494c 100644 --- a/web/src/components/Live/LiveFeedback.tsx +++ b/web/src/components/Live/LiveFeedback.tsx @@ -8,6 +8,12 @@ import { useConfirm } from '@/components/ui/Modal'; interface LiveFeedbackProps { /** Called with the newly active feedback text (or '') after set/clear. */ onChanged?: (text: string) => void; + /** + * Strip the card chrome and the header for the docked strip at the bottom of + * the live stream, where both are redundant: the dock already has its own + * border, and the placeholder already says what the box does. + */ + compact?: boolean; } interface Notice { @@ -19,7 +25,7 @@ interface Notice { // Compact card for steering running agents in real time.
