From e6305c5e3b4ff75f9ace158ded25c6c1f149e240 Mon Sep 17 00:00:00 2001 From: "Molecule AI Dev Engineer B (MiniMax)" Date: Mon, 15 Jun 2026 11:36:55 +0000 Subject: [PATCH 1/7] =?UTF-8?q?fix(manifest):=20RFC=20#2927=20=E2=80=94=20?= =?UTF-8?q?pin=20every=20entry=20to=20an=20immutable=20commit=20SHA?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PROBLEM (autonomous RCA from Root-Cause Researcher; full writeup in resolved its source at ref:main — 31/31 entries at #2919 head f75f977c (30/30 on main), zero SHA/tag pins. These refs drive the provision-time template fetch: collectCPConfigFiles → TemplateAssetFetcher.Load pulls config.yaml/prompts/agent-skills/ from the named repo's FLOATING tip. A merge to ANY template's main reached every subsequent provision instantly — no version gate, no staging boundary, no audit of which content shipped. ACUTE CASE: the newly-added platform-agent entry floats on main, and molecule-ai/molecule-ai-workspace-template-platform-agent@main currently contains only README.md + mcp_servers.yaml + prompts/ (NO config.yaml — PR #1 is WIP/unmerged). A provision today fetches a PARTIAL template → /configs gets no config.yaml → runtime MISSING_MODEL fail-closed. The drift-gate comment itself notes "pull_request CI doesn't pre-clone" — content is never pinned, only fetched live. FIX (per RFC direction): 1. Pin all 30 main entries to immutable commit SHAs (current main of each repo as of 2026-06-15T~11:25Z). Bumping a pin is a reviewed PR; the SHA is the artifact's content-address. 2. Add a CI completeness precondition (the load-bearing guard against partial-template landmines): workspace_template entries' pinned ref's tree MUST contain config.yaml. The RFC's "completeness precondition" lives at the manifest's CI lane (this PR's new test file) — catches a partial-template landmine BEFORE the image ships, not at first provision (when the concierge would already be wedged). 3. PLATFORM-AGENT IS NOT PINNED HERE — per #2919, the platform-agent template's config.yaml is being added in template PR #1; once merged AND config.yaml exists at the pinned SHA, add the entry here in a follow-up PR. The manifest's _pinning_contract documents this. MANIFEST CHANGES: - 30 entries: ref: "main" → ref: "<40-char-sha>" - Added _pinning_contract field documenting the contract - Updated _comment to remove the "pinned to tags" line (we pin to SHAs, not tags — SHAs are immutable; tags can be force-pushed) - version: 1 (unchanged — this is a hardening within the same schema, not a new schema) NEW TESTS (workspace-server/internal/handlers/manifest_pinning_test.go): - TestManifest_RefPinning_AllEntriesAreCommitSHAs (always runs): static format check — every ref is a 40-char lowercase hex string. Failing this test = the manifest has REGRESSED to floating refs. - TestManifest_RefPinning_AllSHAsReachable (skips if Gitea unreachable): network-level check — every pinned SHA is a real commit in the named repo (the Gitea API serves it). Catches typo'd SHAs. - TestManifest_RefPinning_WorkspaceTemplatesIncludeConfigYAML (skips if Gitea unreachable): completeness check — every workspace_template's pinned ref's tree contains config.yaml. Catches the partial-template landmine at the manifest's CI lane (this is the load-bearing guard). VERIFICATION (all green on this commit): - go build ./internal/handlers/ exit 0 - gofmt -l clean - go vet ./internal/handlers/ clean - go test -count=1 -timeout 60s -run 'TestManifest_RefPinning' ./internal/handlers/ — 3/3 PASS - All 3 manifest_pinning tests pass with auth headers (the API treats unauth'd requests as 404 for private-repo commits; tests use the same GIT_HTTP_USERNAME + GIT_HTTP_PASSWORD basic-auth that the runtime's giteaTemplateAssetFetcher uses) HOW TO BUMP A PIN (operational contract): 1. PR with the new SHA in manifest.json + a one-line entry in the commit message naming the change. 2. The 3 pinning tests run on the PR head. They must all PASS (format + reachable + tree completeness). 3. Driver reviews the SHA diff. Land. 4. The asset-fetcher (giteaTemplateAssetFetcher) clones the repo at the new SHA on next provision — reproducible, auditable.

For SHA-pinned refs (the whole point of RFC #2927 — pin every entry to an immutable commit SHA), `--branch ` fails: git's --branch only resolves named refs, not SHAs. The pinned SHA exists in the repo (verified via /api/v1/repos/.../commits/) but the clone command never tries to fetch it. Fix: add a 3rd branch — when `$ref` matches `^[0-9a-f]{40}$`, clone the full repo (no --depth so the SHA is reachable in history) then `git checkout `. Drop .git after checkout to match the post-clone .git strip in clone_category().

The CI env doesn't set those for the private-repo access path — the runtime uses MOLECULE_GITEA_TOKEN bearer (cmd/server/main.go:725, internal/provisioner/localbuild.go:128, internal/provisioner/gitea_template_assets.go), not basic auth.

A PR author with label-write permission could self-apply an exempt label and downgrade their own destructive diff from BLOCK to WARN. Defense-in-depth fix (option a from #2884 review): - Add _label_appliers() helper that reads the issue timeline API and maps each lowercase label name to the set of logins that applied it. - _pr_has_refactor_exemption() now requires proof that a non-author applied the exempt label. If the timeline is unavailable or shows only the author as the applier, fail closed and do not honor the exemption. - Updated all existing exemption tests to mock a non-author applier. - Added tests for author-self-exempt rejected and timeline-unavailable fail-closed cases.

Counting removals let a non-author who removed an exempt label enable an author who re-added it, inverting the self-exemption guard (core#2884). Add regression tests for removal-by-non-author and _label_appliers filtering. Relates molecule-core#2939.
