Canary Context Pack

Product story

Release work should fail before publish when package identity drifts, and post-publish checks should be repeatable without depending on chat memory.

What changed

Adds npm run version:check for package/runtime/lockfile/changelog/release-notes identity.
Adds scripts/set-version.mjs as dry-run-first package metadata bump helper.
Adds npm run dist-tags:check as a manual npm registry verification helper.
Adds a reusable release-notes template and updates the release checklist.

Why it changed

This is a small, useful slice carved out of Gemini's bulk WIP. The original version put an npm registry call inside normal tests; this PR keeps registry access as an explicit release helper instead.

Runtime evidence

npm run version:check
npm test
npm run dist-tags:check
git diff --check

Known constraints

set-version.mjs updates package metadata only. Changelog and release notes remain human-written artifacts.

Explicit out-of-scope

No publishing automation, no package version bump, no CI release job.

Requested decision

approve_merge

Merge blockers

Failing tests or stale release-contract claims.

What lands well

check-version.mjs directly closes PR #39 review T2.1. I flagged version-duplication between package.json and src/types.ts as "smoke catches mismatch via crash, no programmatic guarantee" — and asked for either build-time import or codegen. Codex took the spirit (make mismatch impossible to land) and ran with it by checking more surfaces: package.json + package-lock.json (twice — root + packages[""]) + src/types.ts + CHANGELOG.md + docs/release-notes/<version>.md. Better than my suggestion because it catches changelog/release-notes drift too.
"check": "npm run version:check && npm run build && npm test" wires the gate into the daily developer loop, not just the release checklist. That's the discipline lock — you can't accidentally npm run check cleanly while version files are inconsistent.
set-version.mjs is dry-run by default. Right safety posture for a script that mutates four files. The --execute opt-in is explicit. Semver regex accepts prerelease (0.1.0-alpha.1) which matters for the alpha cycle.
check-dist-tags.mjs is a manual helper, NOT part of npm run check. PR body explicitly carves it out of normal tests because "the original version put an npm registry call inside normal tests" — registry calls in CI = flaky CI. This is the right architectural call.
404 handling in check-dist-tags.mjs treats "package not yet published" as informational, not failure. Pre-publish-safe.
docs/release-notes/TEMPLATE.md is generic enough to be reusable. The "Bounded Context / Wave" section ties release notes to the wave model fallow-ts has been using.
tests/release_identity.test.mjs adds two real tests for the new helpers — dry-run-doesn't-mutate is the key assertion, easy to forget when shipping a write-capable script.

Tier 2 — worth flagging, not blocking

T2.1 The set-version → check-version workflow has an undocumented two-step gate. Concrete scenario:

$ node scripts/set-version.mjs 0.2.0 --execute
# package.json, package-lock.json, src/types.ts updated
$ npm run check
# FAILS — CHANGELOG.md does not contain section: ## 0.2.0
#       — docs/release-notes/0.2.0.md not found

That failure mode is intentional — it forces a human to write changelog + release notes before the bump can merge. PR body acknowledges this ("Changelog and release notes remain human-written artifacts"). But the workflow isn't surfaced anywhere a developer would discover it:

set-version.mjs doesn't print a follow-up reminder like "Next: add ## 0.2.0 section to CHANGELOG.md and create docs/release-notes/0.2.0.md (template at docs/release-notes/TEMPLATE.md)."
docs/release-checklist.md mentions set-version.mjs but doesn't spell out "and then write the CHANGELOG section + release notes file before version:check will pass."

Not blocking — every existing release notes contributor will figure it out from the failure message. But a 3-line print at the end of set-version --execute would save the next contributor 5 minutes of debugging. Tiny follow-up.

T2.2 set-version.mjs doesn't update the golden snapshot. tests/golden/basic-report.txt includes the literal fallow-ts 0.1.0-alpha.2 on line 1. After set-version 0.2.0 --execute, that golden mismatches the analyzer output → npm test fails → human has to either regenerate goldens or strip the version line from the snapshot. Currently the bump-then-check workflow has three hidden human steps (changelog, release notes, golden regeneration), not two.

Fix options (cheapest first):

Have the golden test load VERSION dynamically from package.json and parameterize the assertion — fallow-ts ${pkg.version} — so the golden file omits the version literal entirely.
Have set-version.mjs regenerate goldens as part of the bump (probably over-couples — golden regen should be a deliberate act).
Document the third manual step explicitly.

Option 1 is the most durable. Worth a follow-up issue.

T2.3 set-version.mjs types.ts regex doesn't verify match.

const updatedTypes = typesContent.replace(
  /export const VERSION = "[^"]+";/,
  `export const VERSION = "${versionArg}";`
);
console.log(`- src/types.ts: replaced VERSION constant`);

If the regex misses (typo in the constant name during a future refactor), replace returns the original text unchanged and the script still prints replaced VERSION constant — silent failure. One assertion would catch it:

if (updatedTypes === typesContent) {
  throw new Error("Could not find `export const VERSION = \"...\";` in src/types.ts");
}

Minor, but write-side scripts should fail loud.

Tier 3 — nits

T3.1 check-dist-tags.mjs doesn't validate which tag is correct, just prints what's there. The release checklist tells the human to read the output and verify @alpha exists and @latest wasn't overwritten. Could harden by accepting --expect alpha and exiting non-zero if latest exists when it shouldn't. Enhancement, not bug.

T3.2 No --help on either script. Both have usage prints on error, but not on --help. set-version.mjs --help should probably print the usage block. Cosmetic.

Cross-cutting note

Fallow-ts is now stricter about release-artifact identity than fallow-py is. The version:check script gates more surfaces (lockfile, types, changelog, release notes) than fallow-py's manual checklist line. Worth a future bidirectional convergence — fallow-py could borrow this script pattern. Anti-slop posture: same contract, two implementations.

Verdict

approve_merge. Solid release hygiene that turns previously-manual checklist discipline into automated gates. T2.1 and T2.2 are real follow-up tickets but neither blocks merging this PR. The discipline of separating registry calls (manual) from local validation (auto) is exactly the architectural sense PR #39 was hoping for.
