Subject: [PATCH 3/9] Fix #1641: default the claude consult lane to the 1M
 context window
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`consult -m claude` failed with "Prompt is too long" on any large review —
5 attempts across 2 independent callers on PR #1640 produced no review file,
leaving `porch next 1481` permanently blocked.

Root cause: the lane shipped the bare model id `claude-opus-5`. The Agent SDK's
bundled Claude Code runtime budgets context by model id — its window function
returns 1,000,000 only when the id carries a `[1m]` suffix, and 200,000
otherwise. The claude lane runs agentically (`allowedTools: Read/Glob/Grep`,
`maxTurns: 200`), so an impl or integration review of a 41-file PR reads its way
past 200K and the API rejects the request. The two saved failing sessions show
29 and 51 tool calls with last-successful inputs of 174,521 and 175,930 tokens
before the error — accumulated context, not an oversized opening prompt.

`MODEL_ID_RE` rejected `[` and `]`, so neither `consult.models.claude` nor
`--model-id claude-opus-5[1m]` could work around it. That is why the failure was
unrecoverable rather than merely inconvenient.

Changes:
- `DEFAULT_CLAUDE_MODEL` is now `claude-opus-5[1m]`.
- `MODEL_ID_RE` accepts one optional, case-insensitive `[1m]` suffix, with the
  1-200 character bound now applied to the id as a whole via a lookahead.
- Validator message updated to describe the suffix.
- Mirrored the consult docs in `codev/` and `codev-skeleton/`.

Explicitly configured model ids still pass through unchanged, and `--model-id`
still takes precedence over config. The SDK strips the suffix before the API
request, so the provider still sees `claude-opus-5`.

Regression coverage fails without the production fix (13 failures on baseline
with only the test files applied) and passes with it: the shipped default, the
SDK boundary, configured ids including `[1m]`, CLI override resolution, the
200-character total-length boundary, and malformed suffixes.

+# bugfix-1641 — `consult -m claude` fails with "Prompt is too long"
+
+Issue: #1641. Protocol: BUGFIX (strict). Branch: `builder/bugfix-1641`.
+Base commit: `c4ad613fcda59ad4c996eb59c66794a80e57e7c2`.
+
+## Investigate
+
+Reproduced the failure mechanism from evidence rather than by burning subscription
+quota on another 5-minute review: the two saved failing sessions cited in the
+architect's prior investigation show 29 and 51 tool calls with last-successful
+input of 174,521 and 175,930 tokens respectively, then `Prompt is too long`. That
+is a context-window ceiling at ~200K, not an oversized opening prompt. (The
+opening prompt for `--protocol pir --type impl --project-id 1481` inlines
+spec 2.5K + plan 34K ≈ 10K tokens — nowhere near a limit.)
+
+Root cause, verified against the actual source and the bundled runtime:
+
+1. `packages/codev/src/commands/consult/index.ts:419` —
+   `DEFAULT_CLAUDE_MODEL = 'claude-opus-5'` (a bare id, no context suffix).
+2. The Agent SDK bundles a Claude Code runtime whose context budget is
+   `function jk(q,K){ ... if(ZG(q))return 1e6; ... return qh1}` with
+   `qh1=200000` and `ZG(q)=/\[1m\]/i.test(q)`. A bare `claude-opus-5` is
+   therefore budgeted at **200,000** tokens; `claude-opus-5[1m]` at
+   **1,000,000**. Confirmed by inspecting the bundled `cli.js` in
+   `@anthropic-ai/claude-agent-sdk@0.2.105` (the checkout's locked version);
+   the installed 0.2.141 behaves the same.
+3. `runClaudeConsultation` gives the lane `allowedTools: ['Read','Glob','Grep']`
+   and `maxTurns: 200`, so an impl/integration review of a 41-file PR reads
+   dozens of files and accumulates past 200K → the API returns
+   `Prompt is too long`.
+4. `packages/codev/src/lib/consult-lanes.ts:77` —
+   `MODEL_ID_RE = /^[A-Za-z0-9][A-Za-z0-9._:/@+-]{0,199}$/` rejects `[` and `]`,
+   so **no user could work around it** via `consult.models.claude` or
+   `--model-id claude-opus-5[1m]`. That is why the failure was unrecoverable
+   across 5 attempts and 2 callers.
+
+Why gemini and codex were unaffected: different backends, different context
+budgets — neither routes through the Agent SDK's model-id → window mapping.
+
+Scope: 8 files, +68/−25. Comfortably inside BUGFIX's ~300 LOC ceiling.
+
+## Seeded fix
+
+Architect `main` instructed (2026-09-08T23:32Z) that a tested fix already exists
+and must be imported rather than rewritten:
+`/tmp/codev-1641-builder-handoff-bfow5fso/fix.patch`.
+
+Verified before accepting it:
+- `sha256 = 7c11c00c…33b21` matches `manifest.json`.
+- `git apply --check` clean against my HEAD.
+- Its base commit matches my branch base.
+- Re-derived the new `MODEL_ID_RE` behavior in node against all 15 cases the
+  new tests assert — accepted/rejected sets match exactly, including the
+  200-char total-length boundary (196+`[1m]` ok, 197+`[1m]` rejected) and
+  `opus\n` (JS `$` has no Perl trailing-newline exemption, so it is rejected).
+
+
+## Fix
+
+Imported the seeded patch in two steps so the regression was demonstrated, not asserted:
+
+1. Applied **test files only** (`git apply --include=…` × 4). Baseline run:
+   **13 failed / 345 passed** — `expected 'claude-opus-5' to be 'claude-opus-5[1m]'`
+   and `Invalid model id "claude-opus-5[1m]"` from `validateModelId`.
+2. Applied the **production + docs** files. Same command: **358 passed / 358**.
+
+Verification:
+- All 8 files hash-match `manifest.json` after apply (patch sha256 also matched).
+- `pnpm build` — passed. The 2 residual failures in the first post-fix run were
+  `resolveCodevFile` skeleton-fallback tests that need `copy-skeleton`; they
+  cleared once the build ran. Unrelated to this change.
+- Full `@cluesmith/codev` suite: **5754 passed, 48 skipped, 0 failed** (288 files).
+- `git diff --check` clean; `codev/` and `codev-skeleton/` consult.md byte-identical.
+- Only production consumer of `MODEL_ID_RE` is `validateModelId` — blast radius contained.
+
+Fix is 8 files, +68/−25. Well inside BUGFIX's ~300 LOC ceiling.

Subject: [PATCH 6/9] [Bugfix #1641] docs: correct the review narrative
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three factual corrections from architect review, applied to the PR body and the
builder thread log. No production, test, or shipped-doc change: all eight seeded
files are unchanged and still hash-match the handoff manifest.

1. Over-broad framing of the reported failures. The original narrative implied
   all five attempts on PR #1640 were context failures and generalized to "any
   large review". Four were "Prompt is too long"; the third builder-side attempt
   hit a separate subscription usage limit. Scoped to the observed failures.

2. Over-broad runtime claim. The original narrative said the SDK returns 1M
   "only when the id carries a [1m] suffix, and 200K otherwise". The window
   function has four branches before the 200K fallback — a DISABLE_COMPACT /
   CLAUDE_CODE_MAX_CONTEXT_TOKENS env override, the [1m] suffix, a beta-header
   branch, and a sonnet-4-6-gated branch — so that is not universal. Restated as
   the verified pair: bare claude-opus-5 budgets 200,000 and claude-opus-5[1m]
   budgets 1,000,000, under SDK 0.2.105 and 0.2.141.

3. Over-claimed mechanism. The original narrative said the model "reads its way
   past 200K and the API rejects the request". The saved sessions establish
   substantial prior tool activity and accumulated-context exhaustion surfacing
   as "Prompt is too long" — not a specific client-vs-server rejection point,
   and not that all 41 changed files were read in full.

Also corrected: the gemini lane did not review PR #1640. Its artifact is a
358-byte non-blocking skip notice ("agy exited with code 1"). The original
narrative repeated "gemini wrote its file" from the issue text without opening
the file.

Recorded alongside these: the architect's adjudication of the independent Claude
integration review, and the explicit opt-out now stated in the PR body —
consult.models.claude: "claude-opus-5" retains the previous selection and its
200K budget on the inspected runtimes.

Historical commit b73c5d21d is deliberately left as written; per architect
direction the corrected PR body and this commit are the durable correction,
rather than an amend and force-push that would invalidate green CI and completed
reviews.

 Root cause, verified against the actual source and the bundled runtime:
 
 1. `packages/codev/src/commands/consult/index.ts:419` —
    `DEFAULT_CLAUDE_MODEL = 'claude-opus-5'` (a bare id, no context suffix).
-2. The Agent SDK bundles a Claude Code runtime whose context budget is
-   `function jk(q,K){ ... if(ZG(q))return 1e6; ... return qh1}` with
-   `qh1=200000` and `ZG(q)=/\[1m\]/i.test(q)`. A bare `claude-opus-5` is
-   therefore budgeted at **200,000** tokens; `claude-opus-5[1m]` at
-   **1,000,000**. Confirmed by inspecting the bundled `cli.js` in
-   `@anthropic-ai/claude-agent-sdk@0.2.105` (the checkout's locked version);
-   the installed 0.2.141 behaves the same.
+2. The Agent SDK's bundled runtime derives the context budget from the model id. Its
+   window function `jk(q,K)` has four branches — a `DISABLE_COMPACT` +
+   `CLAUDE_CODE_MAX_CONTEXT_TOKENS` env override, `ZG(q)` (the `[1m]` suffix),
+   `K?.includes(jo)&&UT1(q)` (beta header), and `TV8(q)` (gated, requires
+   `sonnet-4-6`) — before falling through to `qh1 = 200000`. So there is **no** universal
+   "1M with a suffix, 200K otherwise" rule. The scoped, verified fact is narrower:
+   under SDK **0.2.105** (this repo's lockfile) and **0.2.141** (the installed build),
+   bare `claude-opus-5` budgets **200,000** and `claude-opus-5[1m]` budgets **1,000,000**.
 3. `runClaudeConsultation` gives the lane `allowedTools: ['Read','Glob','Grep']`
-   and `maxTurns: 200`, so an impl/integration review of a 41-file PR reads
-   dozens of files and accumulates past 200K → the API returns
-   `Prompt is too long`.
+   and `maxTurns: 200`, so a review of a 41-file PR accumulates context until the 200K
+   budget is exhausted.
 4. `packages/codev/src/lib/consult-lanes.ts:77` —
    `MODEL_ID_RE = /^[A-Za-z0-9][A-Za-z0-9._:/@+-]{0,199}$/` rejects `[` and `]`,
    so **no user could work around it** via `consult.models.claude` or

+
+## Narrative corrections (architect review, PR #1657 comment 5593490746)
+
+Three factual corrections to my review record. All three were right; none required a code
+change, and the eight seeded files are untouched. Applied to the PR body and to the
+Investigate section above.
+
+1. **Over-broad framing of the five attempts.** I wrote that the bug hit "any large
+   review" and implied all five attempts were context failures. Four were; the third
+   builder-side attempt was a subscription usage limit. Scoped to the observed repeated
+   failures on PR #1640.
+2. **Over-broad runtime claim.** I wrote that the SDK returns 1M "only when the id carries
+   a `[1m]` suffix, and 200K otherwise." The window function has four branches before the
+   200K fallback, so that is not universal. Rewritten as the narrower claim I actually
+   verified: bare `claude-opus-5` → 200K, `claude-opus-5[1m]` → 1M, under SDK 0.2.105
+   and 0.2.141.
+3. **Over-claimed mechanism.** I wrote that the model "reads its way past 200K and the API
+   rejects the request." The saved sessions establish substantial prior tool activity and
+   accumulated-context exhaustion surfacing as `Prompt is too long` — not a specific
+   client-vs-server rejection point, and not that all 41 files were read in full.
+
+The gemini correction is the one worth keeping: I asserted "gemini completed normally"
+straight from the issue text without opening the artifact. It is a 358-byte skip notice.
+That is exactly the `lessons-critical.md` line about verifying claims against the actual
+file rather than trusting a summary — and I had already applied that discipline to the
+seeded patch while skipping it on the issue's own prose.
+
+**Outstanding:** commit `b73c5d21d`'s message carries corrections 2 and 3 in its original
+wording. Correcting it means an amend + force-push, which would invalidate the seven green
+CI checks and the completed reviews. Flagged to the architect rather than decided here.
+
+## Architect integration review — disposition (PR #1657 comment 5593523517)
+
+Independent Claude integration review: **COMMENT**, 254.0s, no implementation blocker.
+The architect adjudicated its findings against the SDK rather than accepting them:
+
+1. **"`[1m]` reaches the provider as part of the model id" — rejected.** The reviewer
+   stopped at internal normalization (`X5`). I re-verified the architect's counter-evidence
+   in the locked SDK 0.2.105: `UT(q) = q.replace(/\[(1|2)m\]/gi, "")`, applied at
+   `beta.messages.create({...P, model: UT(P.model)})`, at `countTokens`, and on the bedrock
+   path. Internal normalization keeps the marker; request construction strips it. The
+   context budget and the beta header are separate effects. My PR statement was correct.
+2. **Account/provider availability — advisory, not demonstrated breakage.** Added the
+   explicit opt-out to the PR record as asked: `consult.models.claude: "claude-opus-5"`
+   retains the previous selection and 200K budget on the inspected runtimes, alongside
+   `--model-id` and `CLAUDE_CODE_DISABLE_1M_CONTEXT=1`. No automatic fallback and no
+   entitlement-policy change requested or made.
+3. **Version wording / reflow — non-blocking.** No rewrite of the seeded patch.
+
+Direction taken: correct the narrative in a **new commit**; do not amend or force-push
+`b73c5d21d` to revise historical wording. The corrected PR body and this committed
+narrative are the durable correction — which also resolves the decision I had referred
+upward. The seven green CI checks and completed reviews stay valid.
+
+All eight seeded files remain unchanged and still hash-match the handoff manifest.

Subject: [PATCH 7/9] [Bugfix #1641] docs: record final CMAP verdicts and
 correct the runtime description

All three CMAP lanes returned APPROVE at HIGH confidence with no blocking issues.

Corrects one further narrative inaccuracy of my own, surfaced by the Claude
review. I had written that the context-budget mechanism was "verified against the
bundled runtime in SDK 0.2.105 and 0.2.141". That is wrong for 0.2.141: it has no
bundled runtime. 0.2.105 ships the runtime as cli.js; 0.2.141 is a thin client
carrying no [1m] logic of its own, delegating to a runtime-resolved native binary
from @anthropic-ai/claude-agent-sdk-<platform>. I had taken that half from the
handoff investigation instead of checking it.

Verified directly: the native binary carries the identical gate
rG(H) = /\[1m\]/i.test(H), plus context-1m-2025-08-07 (4 occurrences) and
CLAUDE_CODE_DISABLE_1M_CONTEXT (2 occurrences). The claim was true; the
description of how it was true was not. PR body corrected.

Also re-verified the suffix strip on both runtimes, closing the one item the
Claude reviewer could not confirm: UT(q) in 0.2.105 and KL(H) in the 0.2.141
native binary, both replace(/\[(1|2)m\]/gi, ""), applied at request construction.
The reviewer stopped at X5 normalization, which re-attaches the marker for
concrete ids.

Non-blocking items referred to the architect rather than actioned, because they
would require editing seeded files: the CLAUDE_CODE_DISABLE_1M_CONTEXT doc nuance
and a premium-pricing line in shipped consult.md. The pricing note is recorded in
the PR body instead.

All eight seeded files remain unchanged and hash-match the handoff manifest.

+All three lanes returned. **gemini APPROVE/HIGH**, **codex APPROVE/HIGH**,

+
+Claude's review was the substantive one. It independently confirmed the root cause, the
+regex (superset of the old pattern, ReDoS-safe, 200-char bound correct), and — the check
+I had not thought to make — that admitting `[` and `]` into a validated identifier opens
+no injection surface: the gemini lane passes the id through `spawn(bin, args)` as an argv
+element with no `shell: true`, and `computePersistentOutputPath` keys on the lane name,
+not the model id, so the suffix never reaches a filename.
+
+It also found something that corrected **my** narrative, which is worth recording:
+
+- I wrote that the mechanism was "verified against the bundled runtime in SDK 0.2.105 and

+- Consequence worth knowing, not a blocker: on 0.2.141+ the `[1m]` semantics live in a
+  runtime-resolved binary this repo does not pin (`^0.2.41` spans the architectural

+1. **"Could not verify the suffix-strip claim."** Already adjudicated by the architect and
+   re-verified by me on *both* runtimes: `UT(q)` in 0.2.105 and `KL(H)` in the 0.2.141
+   native binary, both `replace(/\[(1|2)m\]/gi,"")`, applied at request construction. The
+   reviewer stopped at `X5` normalization, which re-attaches the marker. Not a defect;
+   the PR body now shows the evidence on both runtimes rather than asserting it.
+2. **`CLAUDE_CODE_DISABLE_1M_CONTEXT` nuance** (concrete ids keep the suffix on the wire
+   with no beta header; aliases are stripped). Doc line is incomplete, not wrong. Touching
+   it means editing a seeded doc file — referred to the architect, not done unilaterally.
+3. **Premium >200K pricing exposure.** Added a line to the PR body noting `maxBudgetUsd: 25`
+   still caps each consultation and that the exposure exists only where the lane previously
+   hard-failed. A line in shipped `consult.md` would need a seeded-file edit — referred up.
+4. **`consult stats` splits claude history across two model ids.** Cosmetic; noted, not fixed.
+5. **"25 uncommitted lines in the thread log."** True at review time; committed since in
+   `e339b399f`. Resolved.
+
+CI on head `e339b399f`: **all 7 checks pass**.

Subject: [PATCH 8/9] [Bugfix #1641] docs: withdraw three false CMAP
 advisories, correct packaging wording

Narrative-only. No source, test, or shipped-doc change; all eight seeded files
remain unchanged and hash-match the handoff manifest.

Three advisory assertions from the final Claude review do not survive checking,
and one piece of my own wording was misleading. Verified each against the source
rather than accepting the disposition:

1. Disable-context: WITHDRAWN. The review claimed a concrete id keeps [1m] on the
   wire under CLAUDE_CODE_DISABLE_1M_CONTEXT=1. UT(q) = q.replace(/\[(1|2)m\]/gi,
   "") consults neither ZG() nor the env var, and its call site is an unguarded
   beta.messages.create({...P, model: UT(P.model)}). The strip is unconditional.
   The shipped doc line needs no fix.

2. Pricing: WITHDRAWN. The PR body had imported "premium >200K input pricing"
   from the review. Anthropic documents standard model pricing for the 1M window.
   Replaced with the accurate note: longer reviews can consume more total tokens,
   and the maxBudgetUsd: 25 per-consultation cap is unchanged.

3. consult stats split: WITHDRAWN. MetricsDB.summary() groups by model (the lane)
   at metrics.ts:371, not model_id. Recorded concrete ids change as intended, but
   lane totals do not split.

4. Runtime packaging: CORRECTED. My phrasing implied an arbitrary, unversioned
   system CLI. 0.2.141 pins every @anthropic-ai/claude-agent-sdk-<platform>
   optional dependency to exactly 0.2.141 and SDK resolution locates that
   package's binary. The 0.2.105-JS / 0.2.141-native layout distinction is real;
   both are SDK-distributed and version-locked.

This supersedes the two items previously referred to the architect for a possible
seeded-doc edit; both rested on false premises, so no such edit is warranted.

The corrected PR summary is retained rather than the reviewer's generated
PR_SUMMARY, which repeats the original overclaims.

+## Architect disposition of the CMAP advisories (PR #1657 comment 5593577902)
+
+Four of Claude's advisory assertions are false. I verified each before correcting the
+record; the architect was right on all four. **No seeded-file change** — this supersedes
+the two items I had referred upward, both of which rested on false premises.
+
+1. **Disable-context — WITHDRAWN.** The reviewer claimed that with
+   `CLAUDE_CODE_DISABLE_1M_CONTEXT=1` a concrete id keeps `[1m]` on the wire. False:
+   `UT(q) = q.replace(/\[(1|2)m\]/gi,"")` takes no argument but the id, consults neither
+   `ZG()` nor the env var, and its call site is an unguarded
+   `beta.messages.create({...P, model: UT(P.model)})`. The strip is unconditional, so the
+   marker never reaches the wire either way. The shipped doc line needs no fix.
+2. **Pricing — WITHDRAWN.** I had imported "premium >200K input pricing" into the PR body
+   from the review. Anthropic documents standard model pricing for the 1M window. Replaced
+   with the accurate note: longer reviews can consume more total tokens, and the
+   `maxBudgetUsd: 25` per-consultation cap is unchanged.
+3. **`consult stats` split — WITHDRAWN.** `MetricsDB.summary()` groups by `model` (the
+   lane) at `metrics.ts:371`, not `model_id`. Recorded concrete ids change as intended, but
+   lane totals do not split. Verified by reading the query.
+4. **Runtime packaging — CORRECTED.** My own phrasing ("a runtime-resolved binary this repo
+   does not pin") implied an arbitrary, unversioned system CLI. It is not: 0.2.141 pins
+   every `@anthropic-ai/claude-agent-sdk-<platform>` optional dependency to exactly
+   `0.2.141`, and SDK resolution locates that package's binary. The 0.2.105-JS /
+   0.2.141-native layout distinction is real; both are SDK-distributed and version-locked.
+
+The lesson repeats itself in a third variation. I was careful with the seeded patch and the
+SDK internals, then relayed a reviewer's advisory claims into the PR body without applying
+the same standard — the same shortcut that produced the gemini and the 0.2.141 errors. A
+reviewer's summary is evidence, not ground truth, exactly like an issue's prose or a
+plan's claims.
+
+Retaining the corrected PR summary rather than the reviewer's generated PR_SUMMARY, which
+repeats the original overclaims.
