All checks were successful
check / check (push) Successful in 7s
script/cibuild was a plain `docker build .`, and the Dockerfile does `COPY . .` followed by `RUN make check`. Docker invalidates a COPY layer only when the copied content changes, so on an unchanged tree the check layer was served from cache, the suite never ran, and the build still exited 0. Measured here: run 1 took 18.5s and ran the suite; run 2 on a byte-identical tree took 0.286s with `RUN make check` CACHED. script/cibuild and script/docker now assign a per-invocation nonce on its own line and pass it as --build-arg CHECK_EPOCH. The Dockerfile declares ARG CHECK_EPOCH, guards it with `[ -n "$CHECK_EPOCH" ] || exit 1`, and expands it into the check command. Post-fix, two consecutive runs both execute make check (17.4s / 8.1s) with `RUN script/bootstrap` still CACHED, so dependency layers are untouched and the build ceiling is not at risk. The guard is what makes a bare `docker build .` — the command REPO_POLICIES named verbatim — fail closed rather than reuse the empty and therefore stable cache key; verified failing in 0.455s. Holding the epoch constant restores the false green (run 2 fully CACHED), which pins the varying value as the operative mechanism rather than a coincidence. Because the guard references $CHECK_EPOCH it is itself value-keyed: BuildKit renders the epoch into that layer's description and re-runs the layer when the value changes. Each stage therefore has two independent invalidation points, the guard and the expansion, and the guard always precedes the check RUN. Both are kept and the prose now records this; the expansion remains defence in depth and is what puts the epoch in the build log. The false guarantee was org-canonical text in more than one document, so it is corrected everywhere it appeared rather than only where the issue first found it. REPO_POLICIES.md carried it in two places, and its Go multistage template had check steps in two stages; ARG is stage-scoped, so both stages get the treatment or the fleet inherits the half-fixed shape. CODE_STYLEGUIDE_GO.md restated the guarantee for the bare command this change makes fail closed. NEW_REPO_CHECKLIST.md specified the pre-fix script/cibuild verbatim, so every new repo would have been born with the false green, and EXISTING_REPO_CHECKLIST.md ended on a `docker build` acceptance item that the guard makes unsatisfiable by design — an agent working that checklist would have been led to delete the guard to tick the last box. Both checklists' Dockerfile criteria were also satisfiable by a Dockerfile whose check layers are still frozen, and now require the ARG and guard in every check-running stage.

# Workflow
|
|
|
|
- branch (from `main`)
|
|
- do the work in Next Step
|
|
- move Next Step to the top of Completed Steps
|
|
- move the top item of Future Steps into Next Step
|
|
- commit (`TODO.md` changes in the same commit as the work)
|
|
- merge to `main` if the branch is not protected, otherwise open a PR

# Status
|
|
|
|
pre-1.0
|
|
|
|
# Next Step
|
|
|
|
Finish the two draft prompt documents in the working tree and commit them:
|
|
prompts/FIXUP_CLEAN.md (currently a near-empty stub) and prompts/FIXUP_REPORT.md
|
|
(a rough draft). Write the missing content, run `make fmt` so they pass
|
|
fmt-check, and commit.

# Completed Steps
|
|
|
|
- 2026-08-09: Fixed the false green in the canonical CI gate: `script/cibuild`
|
|
and `script/docker` now pass a per-invocation `CHECK_EPOCH` nonce, and the
|
|
`Dockerfile` (plus the Go multistage template in REPO_POLICIES.md, in both its
|
|
lint and builder stages) declares `ARG CHECK_EPOCH` with a guard that makes a
|
|
bare `docker build .` fail closed. Corrected the org-canonical text that
|
|
asserted a successful build implies all checks pass, across every document
|
|
carrying it: `REPO_POLICIES.md`, both repo checklists (which still told agents
|
|
to write the pre-fix `script/cibuild` and ended on an acceptance item the
|
|
guard makes unsatisfiable), and the Go styleguide.
|
|
- 2026-08-07: Set the canonical `.golangci.yml` to the org-standard v2-schema
|
|
config already deployed byte-identical across the org's Go repos (settings
|
|
under `linters.settings` so thresholds like lll/funlen/cyclop/dupl actually
|
|
apply under golangci-lint v2). Recorded the canonical golangci-lint version
|
|
(v2.12.2, commit-pinned) in REPO_POLICIES.md.
|
|
- 2026-03-20: Strengthened constructor naming and Params struct rules in the Go
|
|
styleguide.
|
|
- 2026-03-18: Documented fail-fast Dockerfile lint stage and conditional -v test
|
|
rerun patterns in REPO_POLICIES.md.
|
|
- 2026-03-11: Added HTTP service hardening policy for 1.0 releases.
|
|
- 2026-03-10: Added policy: no build artifacts in repos.
|
|
- 2026-03-04: Added LLM prose tells reference and copyediting checklist, then
|
|
several self-applied revision passes.
|
|
- 2026-02-28: Expanded the pre-1.0 schema migration rule; added clawpub
|
|
reference.
|
|
- 2026-02-23: Added Go style rules (no type-only packages, Stringer for
|
|
string-based types); template repos section in README.
|
|
- 2026-02-22: Initial policy corpus: REPO_POLICIES.md, code styleguides
|
|
(general, Go, JS, Python), repo checklists, CI policy, hash pinning, Go HTTP
|
|
server conventions, repo scaffolding.
|
|
|
|
# Future Steps
|
|
|
|
- Finish, format, and commit FIXUP_CLEAN.md and FIXUP_REPORT.md (the Next Step).
|
|
- Commit this TODO.md at the repo root; it is the last missing policy file.
|
|
- Decide the fate of untracked resume.sh: commit it or delete it.
|
|
- Add more prompt templates for common development tasks (from README TODO).
