Follow-up to the @pymodel/pythinker-code@2.0.0 Release run: https://github.com/PyModel/pythinker-code/actions/runs/35034616438 (Homebrew tap 404). Drift issue: #312

Problem

A future CLI release can go red, or leave users on an old binary, in three ways this PR closes:

  1. changeset publish can succeed several minutes before the public npm tarball URL returns HTTP 200. The Homebrew job fetched once, got HTTP 404, and left the tap on the previous version.
  2. Nightly changeset version --snapshot calls @changesets/changelog-github, which requires GITHUB_TOKEN. The publish job did not set it, so Nightly failed and opened a drift issue even when every live lane matched.
  3. pnpm release:status did not read the Homebrew formula, so a missed tap bump stayed invisible until someone installed.

What changed

  • update-brew-formula.mjs polls the npm tarball (10 minute budget, 15 second interval) until a non-empty 200 body arrives, then hashes it and pushes the formula. Fetch, sleep, and clock are injected so the poll is unit-tested without a network.
  • The brew job timeout is 20 minutes so the poll can finish before GitHub kills the job.
  • Nightly snapshot publish sets GITHUB_TOKEN: ${{ github.token }} and requests pull-requests: read.
  • release-status adds a Homebrew row against Formula/pythinker-code.rb on the tap, so the next nightly fails closed if the formula lags npm.

Native CLI auto-update on 1.11.3 is a separate shipped-client issue (canAutoInstall('native') was false until 1.12.1). This PR does not change that path. 1.11.3 can still stage a newer build with pythinker __update_download <version> or curl -fsSL https://code.pythinker.com/pythinker-code/install.sh | bash.

Summary by CodeRabbit

  • Release Improvements

    • Homebrew formula updates now wait for the npm package to become available, reducing incomplete or failed releases.
    • Release status now verifies that the Homebrew formula matches the published CLI version.
    • Release workflows have improved timing and permissions for more reliable publishing and nightly reconciliation.
  • Bug Fixes

    • Releases now retry temporary package availability issues before failing.
    • Status reporting clearly identifies when the Homebrew version is missing, invalid, or outdated.

changeset publish can succeed several minutes before the public tarball
GET returns 200. The brew job fetched immediately, got HTTP 404, and left
the tap on the previous version. Poll until the tarball is downloadable.

📝 Walkthrough

Walkthrough

The release flow now waits for a downloadable npm tarball before updating Homebrew. It also verifies Homebrew formula alignment and updates workflow permissions and timing.

Changes

Release Verification

Layer / File(s) Summary
NPM tarball polling
scripts/release/update-brew-formula.mjs, scripts/release/update-brew-formula.test.mjs, .changeset/brew-tap-wait-for-npm.md
The script retries failed, non-200, and empty responses within a 10-minute budget. Tests cover success, retries, and exhaustion. The changeset documents the npm availability requirement.
Homebrew release verification
scripts/release/release-status.mjs, scripts/release/release-status.test.mjs
Release status now fetches and parses the Homebrew formula and fails when its version does not match the CLI version. Tests cover aligned and lagging versions.
Release workflow support
.github/workflows/nightly.yml, .github/workflows/release.yml, scripts/release/release-workflows.test.mjs
The nightly workflow adds pull-request read access and passes GITHUB_TOKEN to the publish step. The Homebrew update timeout increases to 20 minutes. Tests verify these settings.

A tarball published during the final polling interval can be missed, causing the Homebrew update to fail and require a rerun or manual intervention.

commit: 546b0fd

Nightly `changeset version --snapshot` needs GITHUB_TOKEN to write
changelog entries; without it the job fails and opens a false drift
issue even when every lane matches. Pass github.token and
pull-requests:read.

The brew job now has 20 minutes so the npm tarball poll can finish.
release-status also reads the tap formula so a missed brew bump is
visible on the next nightly instead of only after a user install.
Comment thread scripts/release/update-brew-formula.mjs Fixed
CodeQL flagged the dummy Error assigned before the fetch loop: every
path overwrites it, so the initial object was dead. Keep lastError
unset until a real fetch failure, and fall back only if the loop
exits without one.

Comment thread scripts/release/update-brew-formula.mjs
Stopping when one full interval no longer fits skipped the final
window. A tarball that appeared in that leftover time was treated as
missing. Sleep the remaining budget and fetch again before failing.

Docstring-coverage warning is not a repo requirement. scripts/release uses a file-level header, not per-function JSDoc, and the comment-free packages (agent-core-v2, agent-gateway, transcript) forbid JSDoc entirely. Required GitHub checks on 546b0fd7 are green without it.

CodeQL unused lastError init: fixed in ee07a655. Leftover poll budget: fixed in 546b0fd7 (sleeps the leftover budget then fetches again before giving up).
