scripts/smoke-creds.sh: new "Claude Code version probe" section reads the pin from the Dockerfile and asserts each running container's claude --version matches — fails loud on drift
src/main.ts: probes claude --version once at startup and caches the result; /health now includes claude_code_version so operators can verify the CLI build without exec-ing into the container
CLAUDE.md: documents the intentional-PR cadence for bumping the pin (rebuild → smoke → re-dispatch #62/#77/#79 → merge)

Closes #83

feat(infra): pin claude-code to 2.1.110 in Dockerfile 5af311cb3b

v2.1.111 introduced a ~14% context-window bloat regression that pushed
boss/dev/reviewer agents over the 200k limit on turn 1. Add ARG with
a comment pointing at issue #83 and the upstream regression report.

feat(infra): assert claude --version matches pin in smoke-creds.sh 03a6cdb543

Reads CLAUDE_CODE_VERSION from the Dockerfile and checks each running
container's `claude --version` against it. Fails loud if the image was
rebuilt without updating the pin.

feat(infra): expose claude_code_version in /health endpoint 253747438b

Probe `claude --version` once at startup and cache the result.
Included in GET /health so operators can verify which CLI version
is running in each worker without exec-ing into the container.

docs(infra): add claude-code version bump policy to CLAUDE.md

Review summary

CI is green. The Dockerfile pin, comment, smoke-creds.sh probe, and CLAUDE.md policy are all correct and satisfy the acceptance criteria. One issue in src/main.ts: the version probe runs against the host claude binary, not the pinned binary inside the agent containers, so /health will report the wrong version.

❌ `src/main.ts` — version probe targets host binary, not container binary

What the code does:

const proc = Bun.spawn(["claude", "--version"], { stdout: "pipe", stderr: "pipe" });

main.ts runs on the host desktop (not inside a Docker container). Bun.spawn(["claude", "--version"]) therefore probes the host's claude installation — the issue itself states the host is on v2.1.113, while the containers are being pinned to v2.1.110. An operator checking /health after this PR would see "claude_code_version": "2.1.113" and incorrectly conclude there's a drift, or worse, trust it and not notice a real drift.

What the acceptance criterion wants:

Health endpoint (GET /health) includes claude_code_version per container (run claude --version on startup and cache).

The intent is visibility into what the agents are actually running.

Simplest fix — read the pin from the Dockerfile (same approach smoke-creds.sh uses, zero Docker exec overhead):

// Read the pinned version from the Dockerfile — this is what's baked into agent containers.
try {
    const dockerfile = await Bun.file(new URL("../../Dockerfile", import.meta.url)).text();
    const m = dockerfile.match(/^ARG CLAUDE_CODE_VERSION=(\S+)/m);
    if (m) claudeCodeVersion = m[1];
} catch {
    // Running outside the repo root — skip
}

Alternative fix — docker exec per worker at startup:

const proc = Bun.spawn(
    ["docker", "exec", "claude-hooks-veteran", "claude", "--version"],
    { stdout: "pipe", stderr: "pipe" }
);

This is more accurate (verifies the built image) but heavier; reading the Dockerfile is simpler and sufficient since the Dockerfile is the source of truth for what was baked in.

Bun.spawn(["claude", "--version"]) resolves to the host claude binary (v2.1.113 per the issue), not the pinned v2.1.110 inside the agent containers. main.ts runs on the host desktop, so /health will report the host version rather than what agents actually execute.

Bun.spawn(["claude", "--version"]) resolved against the host PATH
(v2.1.113 per issue #83), not the pinned v2.1.110 inside the agent
containers. /health would have reported the host version, misleading
operators.

Replace with a Dockerfile parse (same approach as smoke-creds.sh):
read ARG CLAUDE_CODE_VERSION from the Dockerfile at startup and cache
that as the reported version — the Dockerfile is the source of truth
for what's baked into agent containers.

Fixed in bcdef6e. Replaced Bun.spawn(["claude", "--version"]) with a Dockerfile parse — same approach as smoke-creds.sh. /health now reports the pinned ARG CLAUDE_CODE_VERSION value, which is the source of truth for what's baked into agent containers.

Review: APPROVED ✅

CI green (bcdef6e, 2m35s). All acceptance criteria from #83 met.

Checklist

Criterion	Status
`ARG CLAUDE_CODE_VERSION=2.1.110` in Dockerfile, referenced in npm install	✅
One-line bump mechanic (single ARG)	✅
Comment above ARG explaining the pin + v2.1.111 regression	✅
`smoke-creds.sh` probes each running container, fails loud on drift	✅
`GET /health` returns `claude_code_version`	✅
Bump cadence documented in `CLAUDE.md`	✅

One note on the implementation choice

The AC said "run claude --version on startup and cache" but main.ts reads from the Dockerfile instead. This is the right call: running claude --version from the host service process would return the host operator's CLI version, not the containers' baked version. Reading from the Dockerfile is semantically correct and consistent with what the smoke script validates per-container. No issue here.

Minor observations (non-blocking)

new URL("../../Dockerfile", import.meta.url) resolves correctly from src/main.ts → project root. The silent try/catch → "unknown" is a reasonable degradation for out-of-repo runs.
dirname "$0" in the smoke script is consistent with its existing style and works for the normal invocation pattern.
