Outcome

The public MCP contract now names the reachable main-branch commit that owns all 15 tools, and future agents have the squash-merge rule that caused the post-merge failure.

Changes

  • regenerate mcp-tools.public.json from merged main
  • document why a green PR artifact does not prove default-branch provenance
  • correct the agent guide to describe the current three CI jobs and real stdio validation

Validation

  • 75 tests passed
  • Ruff passed
  • mypy passed for 17 source files
  • real MCP initialize and tools/list returned 15 tools
  • manifest regeneration produced no diff

Follow-up to #13 after its authorized merge exposed the exact-revision transition.

Review Change Stack

Walkthrough

The public MCP manifest now records updated provenance metadata. CI/CD and README documentation explain manifest validation, commit ownership, squash-merge effects, regeneration requirements, and pull-request artifact verification.

Changes

Poem

A rabbit hops through manifests bright,
Commit paths tucked in neat and tight.
Squash the branch, then run anew,
Let MCP checks confirm what’s true.
Green artifacts softly glow—
Provenance helps the carrots grow! 🐇

1. **lint** - Ruff checks the server, hosted API, export/smoke scripts, and
tests; mypy checks the server.
2. **test** - Runs all tests with full Git history because provenance tests
read the exact tool-owning commit.
3. **validate-mcp** - Regenerates and rejects drift in
`mcp-tools.public.json`, performs a real MCP `initialize` plus `tools/list`
exchange, and uploads the exact public contract.

A squash merge changes the owning commit ID. Regenerate the checked manifest on
the merged lineage before treating `main` as green. The export may have
identical tool bytes while the provenance revision still needs to change.

Ready to merge. The follow-up refreshes the committed MCP export against the actual squash-merged main lineage. Fresh proof: 75 tests passed, Ruff passed, mypy passed, a real MCP initialize/tools-list exchange returned 15 tools, generator output is clean, and all PR checks are green. Key lesson: a PR artifact proves the proposed bytes; after squash merge, regenerate revision-bearing evidence from the reachable default-branch owner before calling it adopted.
