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.
REPO_POLICIES.md's own Dockerfile criterion carried that same incomplete
form; it is tightened by cross-reference to the CHECK_EPOCH rule rather
than by duplicating the canonical block. The Go template's Key points
gain a caveat that the cache-bust turns the `COPY --from=lint` no-op into
a content-cache hit, so a repo using a file-dependency trick for stage
ordering must re-prove that ordering on a warm cache after adopting it.
That was re-proved in another repo in the org which uses the trick with a
marker file, where the ordering held; the caveat states explicitly that
it was not verified here, this repo being single-stage with no lint stage
to order against.
Requested by sneak.
Sets the canonical `.golangci.yml` to the org-standard v2-schema config already deployed byte-identical across the org's Go repos (vaultik, sfdupes, attrsum, upaas, simplelog, mfer, secret, rgoue, bsfirehose). sha256: `021cc83f4e6fc7c31b95b34b846723dfcf20b66b7baeea1dc40406e643346bcb`.
Why: settings live under `linters.settings`, so the lll/funlen/cyclop/dupl thresholds actually apply under golangci-lint v2. The old canonical file kept them under top-level `linters-settings`, which v2 ignores.
Version note: golangci-lint v2.12.2 tag = commit `c0d3ddc9cf3faa61a4e378e879ece580256d76e5`, recorded for consuming repos. This repo itself has no version pins; the `v2.x.x` / `@sha256:...` strings in `prompts/REPO_POLICIES.md` are intentional placeholders and are unchanged.
Known informational note: this config does not disable the deprecated `gomodguard` linter, so golangci-lint 2.12.x prints a deprecation warning. Harmless, accepted.
Matches dnswatcher PR #96: sneak/dnswatcher#96
Verification: `make check` green (prettier fmt-check on all markdown) after `make fmt`; `.golangci.yml` sha256 verified as `021cc83f...` matching the org-standard file.

Per sneak's instruction:
- Constructors **must** be `New()`, `From<Something>()`, or `NewThing()` (multi-type packages only)
- Strongly discourage creative names (`Create`, `Make`, `Build`, `Init`)
- Constructors **must** use a `Params` struct (or `ThingParams`) for 2+ arguments — no exceptions
- Single obvious argument (`ctx`, bytes) is the only exception
- `context.Context` does not count against the argument limit (already documented)

## Summary
Adds the conditional verbose test rerun pattern as a policy recommendation in REPO_POLICIES.md.
Per sneak's request from [sneak/chat PR #82](sneak/chat#82): document the pattern where `make test` runs tests without `-v` first, then automatically reruns with `-v` on failure for full diagnostic output.
## Changes
**`prompts/REPO_POLICIES.md`** (root `REPO_POLICIES.md` is a symlink to this):
- Added new policy bullet after the `make test` timeout rule
- Explains the rationale: clean CI/Docker build logs on success, full verbose output on failure
- Includes a generic shell pattern template
- Includes concrete Go and Python examples
- Documents that `exit 1` ensures the target always fails after a rerun (the rerun is solely for diagnostic output)
- Updated `last_modified` from 2026-03-12 to 2026-03-18
## The Pattern
```makefile
test:
@go test -timeout 30s -race -cover ./... || \
{ echo "--- Rerunning with -v for details ---"; \
go test -timeout 30s -race -v ./...; exit 1; }
```
- **On success**: concise package summaries only, no per-test noise
- **On failure**: automatic verbose rerun shows every test case and assertion
- **Always fails**: `exit 1` ensures the build fails regardless of second run's exit code

Documents the multistage Docker build pattern we now use across repos (chat, pixa, etc.) where a separate `lint` stage runs `make fmt-check` and `make lint` independently from the build stage.
Key additions to REPO_POLICIES.md:
- Full Dockerfile template showing the lint → build → runtime stage pattern
- Explanation of `COPY --from=lint /src/go.sum /dev/null` as the BuildKit dependency trick
- Handling `//go:embed` placeholders in the lint stage
- CGO/system library notes for the lint stage
- Clarification that tests run in the build stage, not the lint stage
Reference implementations: `sneak/chat`, `sneak/pixa`.

Closes#16
Adds a comprehensive HTTP/web service security hardening policy to `REPO_POLICIES.md` that must be satisfied before tagging 1.0. The policy covers all items sneak specified (without limitation):
**Security headers** — HSTS (min 1 year, includeSubDomains), CSP (restrictive `default-src 'self'` baseline), X-Frame-Options / frame-ancestors, X-Content-Type-Options: nosniff, Referrer-Policy, Permissions-Policy.
**Request/response limits** — max request body size on all endpoints, max response size for paginated APIs, ReadTimeout + ReadHeaderTimeout (slowloris defense), WriteTimeout, IdleTimeout, per-handler execution time limits.
**Authentication & session security** — rate limiting on password-based auth (API keys exempt as high-entropy), CSRF tokens on state-mutating forms (header-auth APIs exempt), bcrypt/scrypt/argon2 for passwords, session cookies with HttpOnly + Secure + SameSite.
**Reverse proxy awareness** — true client IP detection via X-Forwarded-For/X-Real-IP with trusted proxy allowlist (never trust unconditionally).
**CORS** — explicit origin allowlist for authenticated endpoints; wildcard only for public unauthenticated read-only APIs.
**Error handling** — no leaking stack traces, SQL queries, file paths, or implementation details to clients.
**TLS** — HSTS and secure cookie flags required regardless of whether the service terminates TLS directly or sits behind a reverse proxy.
The policy is explicitly non-exhaustive (defense-in-depth: "when in doubt, harden").
Also adds corresponding checklist sections to `EXISTING_REPO_CHECKLIST.md` and `NEW_REPO_CHECKLIST.md` so that HTTP hardening is verified during repo setup and 1.0 preparation.

Add policy rule: build artifacts and code-derived data must not be committed to repos if they can be generated during the build process.
Notable exception: Go protobuf-generated files (`.pb.go`) may be committed because `go get` downloads source but does not execute build steps.

Types should live alongside their implementations, not in separate
'types', 'domain', or 'models' packages. Type-only packages cause
alias imports and indicate poor package design.
