Summary

  • Pin maintainer Bun to 1.4.0 (packageManager, @types/bun, CI). Published engines.bun stays >=1.0.31.
  • Run unit, script, and agent-eval tests with bun test --isolate. Coverage stays without --isolate.
  • Add dedupe:check to check and CI.
  • Rewrite upgrade-packages to gather tarball deltas via bun pm diff, with unit tests.

Test plan

  • bun run test and bun run test:scripts pass
  • bun run dedupe:check passes
  • CI setup uses 1.4.0

Summary by CodeRabbit

  • New Features

    • Upgrade checks now provide compact tarball-based package change evidence, including release notes, changelog links, categorized hints, and relevant file changes.
    • Package discovery now covers root, package, and application manifests while identifying development dependencies.
    • Added stronger handling for cached evidence, failed checks, workspace dependencies, and malformed version ranges.
  • Bug Fixes

    • Improved parsing and deduplication of outdated package information.
  • Documentation

    • Documented Bun 1.4.0 as the required runtime and updated upgrade workflow guidance.
  • Tests

    • Added extensive coverage for version checks, advisory evaluation, package parsing, and tarball differences.

Keep published engines.bun at >=1.0.31. Gather upgrade-packages evidence from bun pm diff, and fail check/CI when the lockfile is not deduped.

📝 Walkthrough

Walkthrough

The upgrade workflow now uses bounded tarball diffs and cached advisory data. It adds parsing and classification tests, pins Bun to 1.4.0, enables isolated tests, and requires dependency deduplication in CI.

Changes

Upgrade evidence workflow

Layer / File(s) Summary
Tarball delta artifact and classification
scripts/upgrade-packages/tarball-delta.ts, scripts/upgrade-packages/tarball-delta.test.ts
Adds bounded tarball diff shapes, patch selection, hint classification, release-note extraction, failure handling, and comprehensive tests.
Evidence collection and parsing
scripts/upgrade-packages/evidence.ts, scripts/upgrade-packages/evidence.test.ts
Updates package discovery, semver and GHSA handling, outdated-table parsing, cache lifetimes, concurrent checks, and tarball diff gathering.
Upgrade workflow guidance
.agents/skills/upgrade-packages/REFERENCE.md, .agents/skills/upgrade-packages/SKILL.md
Documents tarball evidence, failure states, verification sources, reporting rules, and prohibited practices.

Bun repository tooling

Layer / File(s) Summary
Bun version and test execution
.github/CONTRIBUTING.md, .github/actions/setup/action.yml, package.json, lint-staged.config.js
Pins Bun and its type definitions to 1.4.0 and enables isolated Bun test commands across configured test paths.
Dependency deduplication validation
.github/workflows/ci.yml, package.json
Adds dedupe:check and requires the dedupe CI job to pass before ci-complete succeeds.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to d5f03

Package-upgrade evidence can overwrite one workspace’s delta when the same package appears at different versions, producing incomplete upgrade data. Merge should wait for this aggregation issue to be fixed or explicitly accepted; the remaining concerns are bounded follow-ups.

Force dim styles in the clack note test when there is no TTY, and pin transitive tar to 7.5.22 so audit no longer blocks on GHSA-r292-9mhp-454m.

Add doc comments to the exported functions.

buildDelta and failedDelta are the primary exported entry points of this module, and they have no doc comments. The same applies to other exports in this file, for example slimFiles, classifyNote, shouldKeepPatch, isKeepPath, isSkipFile, npmVersionUrl, classifyChangelogLines, addedPatchLines, and extractDate. Only selectPatchPaths has one.

+/** Build a `source: "none"` delta that records why `bun pm diff` failed. */

552-564: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Fall back to a fresh fetch when the cached payload fails to parse.

cachedParsed parses the cached text directly. If a cache file is truncated or corrupt, parse(cached) throws and the caller records a failed delta. With PMDIFF_CACHE_MS set to seven days, the same failure repeats for a week because nothing invalidates the entry.

♻️ Proposed fallback
   const cached = await readCache(key, maxAgeMs);
-  if (cached) return parse(cached);
+  if (cached) {
+    try {
+      return parse(cached);
+    } catch {
+      // Corrupt cache entry — refetch below.
+    }
+  }
   const raw = await fetchText();

In @.github/CONTRIBUTING.md:
- Line 6: Update the Runtimes documentation to state Bun >=1.0.31, matching
package.json, and add concrete examples showing the engines.bun and
packageManager declarations; keep the existing Node and runtime-specific SQLite
documentation intact.

In @.github/workflows/ci.yml:
- Around line 245-261: Document the dedupe job configuration near the dedupe
workflow definition, including an example showing that it depends on skip-ci,
runs only when skip-ci does not request a skip, uses the repository-local setup
action, and executes dedupe:check to validate dependency deduplication.

In `@scripts/upgrade-packages/evidence.ts`:
- Around line 386-403: Update the aggregation in main where deltas and usage are
keyed by package name so rows for the same package across workspaces are not
overwritten; either key records by the unique package/current-version
combination or merge delta lists per package, while preserving all existing
workspace entries.
