Scope: Implement determinism, telemetry, and parameterization for a 3-card poker variant with special doubling rules. Working from a pre-existing prototype. Must-haves: -Deterministic RNG (seeded) with golden replays and a replay verifier. -Parameterized rules via a single config file (bet limits, fees, stake cap, double rules, dealer draw policy, rank/tie rules, max buys, post-double behavior) with validation. -Telemetry conforming to SPEC-TLM-001 (local only), fixed-point per STD-001 via a central Quantizer. -CLI: bj-eval (EVs/CI) and replay (determinism check). -Tests + CI: unit/integration, snapshot EVs vs golden files. -Docs: README, CHANGELOG, JSON schemas, example configs, performance target. A) Definition of Done ( DoD ) Build compiles, runs, and passes tests on a clean machine. Deterministic replay: same seed → same outcome; golden files included. JSON schemas validated; CLI exit codes correct; README explains how to run everything. B) Testing & CI Unit + integration tests for: hand ranking, tie rules, dealer draw logic, doubling lock/skip, buy limits. CI pipeline: build, run tests, run a small deterministic Monte Carlo, compare EV outputs to golden snapshots. C) Replay & Golden Artifacts Replay file format defined (seed, ruleset_hash, actions, outputs). Golden replays shipped in repo; checksum verification step included. D) Config Surface (your “parameterization,” but explicit) One config file (JSON/YAML) listing: bet sizing limits, buy fee, stake cap, double/re-double multipliers, rank/tie rules, dealer draw policy, max buys, post-double rules, toggles for future modes. Validation on load with sensible defaults; reject illegal combos. E) Numeric Policy Fixed-point integers at emission per STD-001 (EV_SCALE/UNITS_SCALE/SCORE_SCALE). Centralized Quantizer; all telemetry and cached EVs pass through it before hashing/logging. F) Telemetry (pointer, not a dissertation) Conform to SPEC-TLM-001 v1.1 INTERNAL. Fields: seed, ruleset_hash, state_hash, action, Q_ev_bp, V_state_bp, outcome, ci_95_bp, samples. Local files, 7-day rotation; no external upload. G) CLI Tools bj-eval CLI: inputs {ruleset, seed/samples}, outputs per-action EV, best action, CI, samples, runtime, version. replay CLI: consumes a replay, verifies determinism, prints mismatches with diffs. H) Performance & Limits Target runtime for a standard sample set (e.g., 100k samples ≤ N seconds on a midrange PC). Memory cap rough limit; graceful fail with clear error messages. I) Error Handling & Logging Structured errors, non-zero exit codes on failure. Debug logs behind a flag; no secrets, no PII. J) Documentation & Handoff Short README with: setup, run commands, config reference, known caveats. CHANGELOG noting any ruleset or comparator changes that affect replays. Proper Parameterization 1.
