Summary

Parallel maintenance task: make the root repository README.md factually current against the repository implementation and roadmap state, synchronized with latest origin/main (47a834400677fa3cea7ed8b80eca8bcea0530e41).


Stale Claims Found & Corrected

  1. Status Banner & Milestone Status:

    • The status banner previously stated: "Milestones 1–9, M12 (security hardening), and M13 (observability & SRE) are complete; M10 (social & learning), M11 (search), and M14 (deployment & scale) have delivered increments and remain in progress".
    • It omitted Milestone 15 entirely and did not reflect that M10, M11, and M14 have shipped core domain, persistence, API, and web UI surfaces.
    • Correction: Updated status banner to reflect completion of M1–9, M12, M13; delivery of core packages and UI for M10, M11, M14; and active productionization and hardening tracked in M15.
  2. AI Feature Counts:

    • Status banner and monorepo layout table hard-coded "nine AI features" and "(9 features)".
    • Correction: Replaced brittle hardcoded counts with durable capability phrasing: coaching, move explanations, puzzle generation, opening exploration, endgame training, and tournament commentary.
  3. Monorepo Layout Table:

    • engine/ was described narrowly as "Stockfish-backed analysis engine: eval, best lines, UCI bridge".
    • Correction: Updated to "UCI engine bridge & analysis orchestrator: Stockfish/Fairy-Stockfish, pools, scheduling", fully aligned with canonical packages/engine/README.md.
  4. Core Rules & Perft Coverage:

    • The original perft claim stated correctness was proven by perft against published reference node counts for only "(start position, Kiwipete, and three EPD edge-case positions)", pre-dating Chess960 and the expanded variant perft suites.
    • Initial refresh broadened to reference perft test suites for standard chess, Chess960, and supported variants. CodeRabbit review noted that stating "Correctness proven by perft" overclaimed what perft establishes (it validates move generation, not the complete chess engine). Corrected in commit 86cb400570221bb314d06631087b397874f837b9 to "Move-generation correctness validated by perft".
  5. Realtime Gateway Algorithmic Load Benchmark:

    • The fanout load test (p99 < 50ms with 5,000 active and 50,000 idle connections) lacked context that it is an in-process benchmark using in-memory connections validating algorithmic scaling, risking confusion with production cluster capacity.
    • Correction: Clarified as an in-process fanout benchmark validating algorithmic scaling in memory.
  6. Realtime Gateway Code Example Defect:

    • In the snippet, new RealtimeGateway(authority, pubsub, { tokenVerifier }) passed an object wrapper instead of the TokenVerifier instance expected by RealtimeGateway's constructor (authority, pubsub, tokenVerifier, now).
    • Also authority.createGame is async and was un-awaited.
    • Correction: Fixed snippet to instantiate and pass a typed tokenVerifier directly, and await authority.createGame(...). Verified via executable test.
  7. API Identity Surface:

    • The identity bullet described only scrypt, access tokens, and refresh tokens, omitting WebAuthn passkeys, session visibility and revocation, password recovery, and email verification shipped in M14/M15.
    • Correction: Updated bullet to list WebAuthn passkeys, session visibility/revocation, password reset, and email verification.
  8. Obsolete Engine Section:

    • Described an early conceptual API: evaluate(position, depth?), bestLines(position, { multiPv, depth }), InMemoryEngine, and StockfishEngine. None of these symbols exist in @chess-platform/engine.
    • Correction: Replaced with current architecture: AnalysisProvider interface (analyze, play, capabilitiesFor), EngineManager with priority scheduling (JobPriority), per-plugin EnginePools (Stockfish and Fairy-Stockfish), and EngineTransport seams (FakeEngineTransport for tests, ChildProcessTransport for native subprocesses, and createEngineManager()). Synchronized with canonical PR docs(engine): remove stale test and deployment claims #36 engine docs.

Reviewer Finding History

  • CodeRabbit Review Finding (commit 8853caf7ee11f21ad163d6a0f71e3c528a3bdee8):
    CodeRabbit noted that the refreshed line stated "Correctness proven by perft", which overclaimed what perft establishes: perft validates move-generation counts at tested depths, not the entire chess engine (such as clocks, draw rules, or parsing).
  • Resolution (commit 86cb400570221bb314d06631087b397874f837b9):
    Scoped claim to "Move-generation correctness validated by perft". Thread marked resolved (isResolved: true).
  • Full Re-Review (commit 341cf109c19ddc91b495830aa58dd7495d3a0c6a):
    • CodeRabbit: Review completed (pass), 0 actionable comments, Merge Risk Minimal, 5 pre-merge checks passed.
    • Qodo: Review completed, 0 findings (skipped on merge commit due to no code changes beyond previous review).

Exact Final Scope & Diff

Validation Performed

  • git diff --check (Passed cleanly, 0 whitespace issues)
  • npm run check:adr-claims (Passed: 141 ADRs checked, 0 drift)
  • npm run check:ci-parity (Passed: 19 commands checked)
  • npm run check:variant-parity (Passed: all 6 copies agree with chess-core Variant)
  • npm run check:engine-pin-parity (Passed: all 4 locations pin the same Stockfish artifact)
  • npm run test:scripts (Passed: 132 tests passing)
  • Package builds: @chess-platform/core, @chess-platform/game, @chess-platform/realtime-gateway, @chess-platform/engine all built cleanly
  • Code snippet execution: verified executable against live package exports
  • CI workflow status: GitHub Actions CI (ci.yml and pin-parity.yml) has path filtering (paths: ['**', '!**/*.md']), meaning markdown-only PRs do not trigger Actions CI workflows; CI is path-filtered/skipped as intended.

AI Description

• Align milestone status and package summaries with the implementation and M15 roadmap.
• Replace brittle AI counts and narrow capability claims with durable descriptions.
• Correct realtime benchmark context and the TypeScript gateway example.

High-Level Assessment

Directly reconciling the root README with package implementations and the roadmap is the appropriate approach. Replacing the overview with links to package documentation was considered, but that would reduce repository-level discoverability and would not correct the stale summary or broken example.

Synchronize platform overview with current implementation

• Refreshes milestone, AI, engine, perft, identity, and realtime descriptions to reflect current capabilities. Clarifies that the fanout result is an in-process algorithmic benchmark and fixes the gateway example to provide a typed token verifier and await game creation.

- Line 82: Update the README perft bullet to scope the claim specifically to
move-generation correctness for the tested positions and depths, replacing the
broader “Correctness proven” wording without implying the complete chess engine
is proven correct.
