Record the exact-head CI runs in the ledger.

PR #4155 correctly uses 3b9fab90e as its current head. Successful runs exist for that SHA, including Cross-platform CI 34411292481 and React Doctor 34411292469. Keep 9abb66387 and run 34410586758 as the round-opening evidence, but add the current run IDs to the roadmap row. Also record exact-head run IDs for A1, such as 34413236789, and A2, such as 34415035528, so every green entry satisfies the rule in lines 76–77.

P2 Badge Record the tested head for #4160

The #4160 row declares CI green while leaving Head empty. Because this is a stacked child that can receive additional commits, the ledger cannot establish which revision was tested, contradicting its exact-head evidence requirement and allowing a later reader to mistake stale CI for current validation; record the verified head SHA or leave the CI status unset.

P2 Badge Keep #4153 pending until cross-platform CI completes

This row marks #4153 as green, but _research/_audit_pr4153.md explicitly records that only the lightweight fork checks have run and that Cross-platform CI still needs maintainer approval. Since remote CI is this round's only product-test gate, the ledger can incorrectly signal that this contributor change is ready to merge; leave the status pending/action-required until the repository CI run succeeds at this head.

A1 and A2 were audited again **after** they landed, against `origin/dev` rather
than against the lane's own report. Both match the fix the plan chose, both
regression tests are genuinely red on the old code, and nothing the plan named as
"must stay green" was deleted to make the suite pass. Record:
`_research/_audit_wp2.md`.

One behaviour worth knowing, found by that audit and not by the change itself: a
Claude request carrying **only** in-messages system text and no `metadata.user_id`
now emits no `prompt_cache_key` at all, because the fallback hashes `systemParts`
and that is empty once the reminders move into the timeline. That is absence, not
rotation — before the change those turns produced a key that moved every turn — so
it is an improvement, but a request in that exact shape no longer gets a proxy-set
key.

## Decisions taken during the round

Record each one here as it happens, with who decided and on what evidence. A
dropped item is a decision, not a gap — say why it was dropped and leave the issue
open with a comment explaining the state it was left in.

**Lane re-split, main session, after the roadmap audit.** #1711 moved from Lane A
to Lane B because the two lanes' write sets overlapped in
`src/codex/catalog/parsing.ts`, `provider-fetch.ts` and `Models.tsx`. Lanes are
now 3 and 5. Evidence: `_research/_audit.md` finding 8, commit `9abb66387`.

**#4148 scope, main session, recorded in the plan and the PR body.** Every
in-messages system message becomes a developer item, not only the ones after the
first user turn. A leading-only hoist keeps the old test green while still
mutating `instructions` when a client injects a fresh leading system message each
turn, which is the reported failure.

**#4141 held, main session.** It must rebase onto PR #4152, which rewrites the
same `runLaunchctl` runner and belongs to the separate task investigating the
live-proxy shutdowns. Lane A was told to hold rather than invent a second seam.

**Lane B dammed by the UI-screenshot gate, escalated to the maintainer.**
`enforce-target` requires a screenshot whenever a PR mentions `gui` and auto-drafts
until one exists, so #4156 and #4158 fail on that alone with every other check
green. Producing one needs `bun run build:gui`, which this round's no-local-build
constraint forbids. #4160 is fully green but sits behind them. Lane B reported
itself blocked rather than working around the gate, which is the correct behaviour.

## Rules this record exists to enforce

- A PR is only "merged" here once `git fetch origin && git merge-base --is-ancestor`

**1. Import and sanitizer — NOTE**
`sanitizeCodexReasoningEfforts` exists at [src/reasoning-effort.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/reasoning-effort.ts:130). The new import in [src/clients/config-export/zcode.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/zcode.ts:4) (`../../reasoning-effort`) is the same path [src/clients/config-export/mcode.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/mcode.ts:4) already uses, and it resolves to `src/reasoning-effort.ts`.

It keeps only exact `none` / `minimal` plus the Codex set `low|medium|high|xhigh|max|ultra`, drops duplicates, then sorts by that ladder ([src/reasoning-effort.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/reasoning-effort.ts:5), [src/reasoning-effort.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/reasoning-effort.ts:137)). It does not trim or lowercase. `turbo` is rejected there, not in the ZCode filter: it is not a sentinel and not in `CODEX_REASONING_SET`. After sanitize, `["none","high","ultra","turbo"]` is `["none","high","ultra"]`; [src/clients/config-export/zcode.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/zcode.ts:78) then drops `none`, which is why the second test expects `["high","ultra"]` ([tests/providers/zcode-client.test.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/tests/providers/zcode-client.test.ts:129)).

**2. Export model fields vs omp/dsh — NOTE**
The loop is `for (const model of normalizeExportModels(ctx.models))` ([src/clients/config-export/zcode.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/zcode.ts:59)). `normalizeExportModels` returns `ExportModel[]` unchanged except Fast expansion/sort ([src/clients/config-export/model-metadata.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/model-metadata.ts:91)). `ExportModel` has `reasoningEfforts` and `defaultReasoningEffort` ([src/clients/config-export/contracts.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/contracts.ts:69)).

The three exporters all read `model.reasoningEfforts`, but they are not the same schema:

- omp: client vocab without `ultra`/`none`; `reasoning: true` + `thinking.efforts` + optional `defaultLevel` ([src/clients/config-export/omp.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/omp.ts:40))
- dsh: map `low|medium|high|xhigh|max`, with `ultra` as `max: "ultra"`; no default ([src/clients/config-export/dsh.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/dsh.ts:48))
- zcode: same sanitize-then-drop-`none` ladder as mcode, plus omp-style default gating

That is consistent for this client. The issue’s “like omp/dsh” means “read the catalog fields,” not copy those on-disk shapes.

**3. 3.7.7 / 3.8.1 comment vs new `reasoning` — NOTE**
The 3.7.7 / 3.8.1 JSDoc is the provider-entry observation (`kind`, `apiKeyRequired`, loopback key) sitting above `ZcodeModelEntry` ([src/clients/config-export/zcode.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/zcode.ts:8)). It never asserted `levels` or `variants`. Optional `reasoning` does not contradict those provider claims.

This repo already treats on-disk `reasoning` as a ZCode 3.8.1 model key, with `enabled` / `variants`, not `levels`: [src/integrations/ownership-policy.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/integrations/ownership-policy.ts:58) and the writer fixture `{ enabled: true, variants: ["off", "high"] }` ([tests/clients/integrations-writer.test.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/tests/clients/integrations-writer.test.ts:369)). That agrees with the new field and with the issue’s Expected block. The issue reproduction’s `model.reasoning.levels` is not a disk contract this tree records. `openCodeReasoningToModelReasoning` is contributor evidence, not something this repository proves.

**4. Goldens / snapshots — NOTE**
The only byte-pinned ZCode export string is the facade golden in [tests/config/client-config-export.test.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/tests/config/client-config-export.test.ts:123), and the PR updates it. [tests/providers/zcode-client.test.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/tests/providers/zcode-client.test.ts:52) still exact-equals models that have no `reasoningEfforts`, so they stay reasoning-free. Writer tests use models without ladders ([tests/clients/integrations-writer.test.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/tests/clients/integrations-writer.test.ts:40)). Docs samples do not pin ZCode model JSON. No other snapshot in this tree now disagrees.

**5. Consumers — NOTE**
Callers that need the optional field:

- [src/clients/config-export/zcode.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/zcode.ts:57) `buildZcodeClientConfig` (writes it)
- [src/clients/config-export/zcode.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/zcode.ts:113) `buildZcodeContribution` (whole provider fragment, field flows)
- [src/clients/config-export.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export.ts:49) registry `build` / `buildContribution`
- type re-export [src/clients/config-export.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export.ts:37)
- tests above

`summarizeZcode` only counts `limit` ([src/clients/config-export/zcode.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/zcode.ts:108)). Ownership already lists `models.*.reasoning` as refreshable ([src/integrations/ownership-policy.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/integrations/ownership-policy.ts:79)), so ZCode rewriting that key stays stale/refreshable, not a foreign edit. No extra consumer update is required.

**6. `defaultVariant` omission and case — NOTE**
Omission is correct: `defaultVariant` is spread only when the trimmed/lowercased default is still in the emitted ladder ([src/clients/config-export/zcode.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/zcode.ts:81)). Default `"none"` is filtered out, so the Muse Spark case has no `defaultVariant` ([tests/providers/zcode-client.test.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/tests/providers/zcode-client.test.ts:148)).

Lowercase/trim is safe on the catalog path. Management/CLI store defaults as exact declared tokens (`none|minimal|low|medium|high|xhigh|max|ultra`) with no mixed case ([src/server/management/model-routes.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/server/management/model-routes.ts:63), [src/cli/models.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/cli/models.ts:66)). `toLowerCase()` is idempotent there and matches omp ([src/clients/config-export/omp.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export/omp.ts:74)). Sanitize still requires exact lowercase on the ladder itself; that is also how the catalog is stored.

**7. Maintainer issues**

- **NOTE (preference, not defect):** #4147’s Expected snippet filters `ultra`. Keep `ultra`. ZCode forwards the selected variant as `reasoning_effort`, and `ultra` is a real Codex rung ([src/reasoning-effort.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/reasoning-effort.ts:11)). omp’s no-`ultra` vocab is omp-only.
- **NOTE (preference, not defect):** `minimal` survives, same as mcode and OpenCode V2 ([src/clients/config-export.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/clients/config-export.ts:585)). Hide it only if ZCode’s picker must not show that sentinel.
- **NOTE:** Emitting `reasoning` while still marking it refreshable means ZCode can rewrite OpenCodex’s ladder (the writer test uses `off` / `enabled: false`) and refresh puts the catalog block back. That matches existing 3.8.1 policy, not a merge blocker.
- **NOTE:** Docs checklist is ticked with no docs-site change. The integrations guide does not pin this schema; not a correctness fail.
- **NOTE:** Fork CI in `gh pr checks` is hygiene/target/label/resolve-pr/CodeRabbit only. Cross-platform CI still needs maintainer workflow approval before treating remote tests as proof. Touched files are unchanged between PR base `a7509fe00` and current `origin/dev` `4498fb910`, so this slice should merge cleanly.

No correctness, contract, or security defect that should block merge. The loopback placeholder is unchanged.

Both landings match the chosen fixes. The regression tests would be red on the old code, and the “must stay green” cases were not weakened.

**NOTE** Local checkout is behind `origin/dev`. Grep in this worktree will still show the old hoist test.

## #4129 / PR #4157 (`4498fb910`, head `421aea87a`)

The lane implemented the plan, not a swap of the two blocks.

In `handleResponsesInner`, a combo-named `shadowCallIntercept` is rewritten **before** `comboIdFromRawBody`:

```3313:3336:src/server/responses/core.ts
if (!options.comboAttempt && body && typeof body === "object" && !Array.isArray(body)) {
const shadowIntercept = config.shadowCallIntercept;
const rawShadowModel = (body as { model?: unknown }).model;
if (shadowIntercept?.enabled && shadowIntercept.model && typeof rawShadowModel === "string"
&& isShadowSourceModel(rawShadowModel, shadowIntercept.sourceModels)) {
const shadowComboId = resolveComboId(config, shadowIntercept.model);
if (shadowComboId && Object.hasOwn(config.combos ?? {}, shadowComboId)) {
(body as Record<string, unknown>).model = shadowIntercept.model;
logCtx.shadowCallRewrittenFrom = sanitizeLogMetadataString(
shadowSourceModelPrefix(rawShadowModel, shadowIntercept.sourceModels),
);
}
}
}
const comboId = !options.comboAttempt ? comboIdFromRawBody(body, config) : null;
if (comboId && Object.hasOwn(config.combos ?? {}, comboId)) {
return handleComboResponses(...)
```

Identity is `resolveComboId` in [src/combos/identifiers.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/combos/identifiers.ts) (`parseComboModelId` + alias scan). That is config lookup. It does not go through `routeModel` / `tryPickComboModel`.

The late site still uses `shouldInterceptShadowCall` for direct replacements ([src/server/responses/core.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/server/responses/core.ts) ~3504–3527). Combo children pass `comboAttempt: true` ([src/server/responses/core.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/server/responses/core.ts) ~2880), so they skip both the early rewrite and `comboIdFromRawBody`. Child bodies are `provider/model`; `isShadowSourceModel` hard-excludes slash ids, so the late site cannot recurse either.

`shadowCallRewrittenFrom` is still the sanitized prefix, same helper as the late site. Success-path `Object.assign(logCtx, childLog, …)` does not copy that field off the child, and the new tests assert the marker after combo return.

**Tests.** [tests/responses/responses-shadow-intercept.test.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/tests/responses/responses-shadow-intercept.test.ts) gained the planned cases:

- Hop: 429 then 200 → `urls` length 2, `logCtx.provider === "combo"`, `routeKind === "combo"`, `shadowCallRewrittenFrom === "gpt-5.6-luna"`, attempts `xai/grok-4.5` then `alt/grok-4.5` (lines 298–326). Red without the rewrite: `comboIdFromRawBody` still sees `gpt-5.6-luna`, so there is no failover loop.
- Intersecting first target: one upstream call, marker set, `routeKind === "combo"` (lines 329–359). Red without the rewrite: collapsed pick hits `shouldInterceptShadowCall` and leaves a native route with no marker.
- Extra keep-green: non-combo replacement still uses the late intercept (lines 362–377).

Existing #2706 self-target and prefix-log tests were not edited. `421aea87a` only retargeted the **new** fixture off the pinned `openai` provider after CI proved the combo hop, then 401’d on `chatgpt.com`. Same intersect condition, using `sourceModels: ["custom-helper"]` and first target `xai/custom-helper`.

**NOTE** [src/server/management/shadow-call-validation.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/server/management/shadow-call-validation.ts):7 still validates via `routeModel`, so a dashboard PUT of a Luna-first `combo/shadow` can still 400. Plan called this follow-up unless trivial.

**NOTE** `parsed._cursorIsolateConversation` is still not plumbed onto combo children. Plan deferred that.

## #4148 / PR #4161 (`5b8f1fcfa`, head `799330bcf`)

Matches the policy choice: **every** in-messages `role: "system"` becomes a chronological `developer` item, not a leading-only hoist.

[src/claude/inbound.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/claude/inbound.ts):329–360: top-level Anthropic `system` still goes through `systemToInstructions` into `systemParts` → `body.instructions`. In-messages system is pushed as `{ type: "message", role: "developer", content: [{ type: "input_text", text }] }`. No `role: "system"` input item.

`parseRequest` still re-hoists `role: "system"` onto `systemPrompt` and keeps `developer` as a timeline message ([src/responses/parser.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/responses/parser.ts) ~246–258). Using `developer` is the only shape that survives that parser.

**`prompt_cache_key`.** The fallback still hashes `systemParts` ([src/claude/inbound.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/src/claude/inbound.ts):385–402), now **only** top-level system. With top-level `system: "S"` and no `metadata.user_id`, the key is stable across turns (tested).

If a request has **only** in-messages system and no `user_id`, `systemParts` is empty, so **no key is emitted** (`cacheKeySource = null`). That is absence, not rotation. Previously those turns hashed the reminders and the key moved. The plan’s test used top-level `"S"`; the existing “no metadata + no system: no key” case (line 532) still describes this edge.

**Tests.** [tests/claude-integration/claude-inbound.test.ts](/Users/jun/.codex/worktrees/ae6a/opencodex/tests/claude-integration/claude-inbound.test.ts):

- Old hoist test rewritten at 335: `instructions === "top-level"`, input roles `["developer","developer","user"]`, no `role === "system"`. Red on the old fold (`"top-level\n\nbe terse\n\nblock form"`).
- New #4148 case at 359: `turn1.instructions === turn2.instructions === "S"`, roles `["user","developer","assistant","user","developer"]`, texts `u1,r1,a1,u2,r2`, `prompt_cache_key` equal, schema + `parseRequest` both succeed. Red if reminders still land in `instructions`.

Top-level-system cases at the old :66 / :429 / :439–492 sites were left as-is (now ~83, 497, 511+). Nothing in that file was deleted to stay green; the one rewritten test is the contract change the plan named.

**NOTE** Out of scope as planned: `src/adapters/openai-chat.ts` still re-hoists developer text into a leading `system` chat message for non-`api.openai.com` Chat Completions. DeepSeek/SenseNova stay on the old prefix-bust path. Anthropic/Google outbound still present developer items as chronological `user`.

No new secret logging, no `role: "system"` on the Responses wire, marker still sanitized. I do not see a contract or security blocker in either diff.
