Summary

  • Pin the private monorepo root to Bun 1.4.0 (packageManager, @types/bun, CI, root engines.bun). Published adapters keep >=1.0.0.
  • Add --isolate to each package test script. Root test also runs scripts/upgrade-packages because the workspace filter cannot see it. Coverage stays without --isolate.
  • Replace upgrade-packages with a bun pm diff gatherer, tests, and an agents skill.
  • bun dedupe is not wired — this workspace lockfile still fails does not match package.json.

Test plan

  • bun run test passes (packages + upgrade-packages)
  • CI setup uses 1.4.0

Summary by CodeRabbit

  • New Features

    • Added an evidence-based workflow for evaluating and upgrading Bun packages, including security advisories, compatibility risks, usage checks, and verification guidance.
    • Added structured upgrade evidence covering package changes, release notes, security findings, and audit information.
  • Improvements

    • Standardized the project on Bun 1.4.0 and documented the updated minimum runtime requirement.
    • Improved upgrade analysis reliability with caching, bounded data collection, and clearer error handling.
  • Tests

    • Enabled isolated test execution across packages and included package-upgrade checks in the root test command.

Root packageManager/CI/engines move to 1.4.0; published adapters stay at engines.bun >=1.0.0. Root test also covers scripts/upgrade-packages.

📝 Walkthrough

Walkthrough

The PR adds an evidence-first Bun dependency upgrade skill and artifact reference. It introduces tarball delta processing, advisory and outdated-package parsing, concurrent evidence collection, validation tests, Bun 1.4.0 pinning, and isolated test execution.

Changes

Package upgrade evidence

Layer / File(s) Summary
Bun runtime and test baseline
.github/CONTRIBUTING.md, .github/actions/setup/action.yml, .oxfmtrc.json, package.json, packages/*/package.json
The repository now uses Bun 1.4.0 metadata and setup. Root and package tests use isolated execution. Upgrade artifacts are excluded from formatting.
Tarball delta processing
scripts/upgrade-packages/tarball-delta.ts, scripts/upgrade-packages/tarball-delta.test.ts
The new module processes bun pm diff --json data, applies file and size limits, classifies hints, extracts release details, and records failures. Tests cover helper and integration behavior.
Advisory and outdated analysis
scripts/upgrade-packages/evidence.ts, scripts/upgrade-packages/evidence.test.ts
The evidence module adds stricter semver handling, advisory verdicts, workspace discovery, normalized outdated-table parsing, duplicate detection, cached GHSA fetching, and tests for exported helpers.
Evidence collection workflow
scripts/upgrade-packages/evidence.ts, .agents/skills/upgrade-packages/*
Evidence collection now uses cached and concurrent Bun diff operations, usage fallbacks, concurrent audit and GHSA checks, and guarded execution. The skill and reference describe artifact fields, commands, citations, errors, and upgrade phases.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to b789f

The PR pins Bun and changes package-test execution while adding upgrade-package tooling. Ubuntu CI does not run the root test command, leaving that new path untested in CI; localized cache-corruption and semver-classification follow-ups also remain. The PR is mergeable with explicit owner awareness, but CI should run the root test command.

226-228: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

The 0.x branch and the fallthrough return the same expression.

Line 227 and line 228 are identical. The ca === 0 check therefore changes nothing. Either delete the branch, or implement the intended 0.x rule if a 0.x minor bump must classify as major.

♻️ Proposed simplification (behavior unchanged)
   if (la !== ca) return "major";
-  // 0.x: second digit is the minor
-  if (ca === 0) return lb !== cb ? "minor" : "patch";
   return lb !== cb ? "minor" : "patch";

556-568: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

A corrupt cache entry keeps failing until the TTL expires.

cachedParsed passes cached text straight to parse. If a cache file is truncated or invalid, parse throws on every run. For gatherDeltas the throw becomes a failedDelta, and the bad file stays valid for PMDIFF_CACHE_MS (7 days), so that package reports an error until someone deletes .cache/ by hand.

Treat a cached-parse failure as a cache miss.

♻️ Proposed fix
 async function cachedParsed<T>(
   key: string,
   maxAgeMs: number,
   fetchText: () => Promise<string>,
   parse: (raw: string) => T,
 ): Promise<T> {
   const cached = await readCache(key, maxAgeMs);
-  if (cached) return parse(cached);
+  if (cached) {
+    try {
+      return parse(cached);
+    } catch {
+      // corrupt or stale-shaped cache entry — refetch
+    }
+  }
   const raw = await fetchText();
   const value = parse(raw);
   await writeCache(key, raw);
   return value;
 }
