alvis	7281af83a4	feat(bandit): promote egreedy-v2 (D=12, profile features) as active policy (#99) ... Offline sim gate passed — egreedy-v2 mean reward −0.629 vs egreedy-v1 −0.642 (5 users × 20 rounds, rule judge, seed 42). v2 wins 3/5 personas. - recommender.ts: switch remotePolicy() to /score/egreedy/v2 - recommender.ts: switch sendRewardWithRetry() to /reward/egreedy/v2 with profile_features payload so the ridge update uses the full D=12 vector - recommender.ts: re-fetch profile at feedback time (TTL-cached, near-instant) - ADR-0012: status Accepted → Promoted, promotion record appended Shadow entry egreedy-v2-shadow kept in registry (active: false) for rollback.

alvis	2d7cf217a9	feat(ml): egreedy-v2 shadow policy — D=12 with profile features (#99) ... Ship the scaffolding for #99 (phase B.3 of #81): - ml/serving: add /score/egreedy/v2, /reward/egreedy/v2, /stats/egreedy/v2 endpoints (D=12). New feature dims: completion/dismiss rates, mean dwell (clipped 10min), preferred-hour alignment (cosine, 1-dim), tip volume (log). Separate state file per user (_egreedy_v2.json). /reset clears v2 state too. - ADR-0012: documents D=7→12 dimension change, normalization choices, shadow rollout protocol, and promotion gate (offline sim win per ADR-0002). - recommender.ts: register egreedy-v2-shadow in shadow-policy map (disabled by default). When enabled, calls /score/egreedy/v2 fire-and-forget and publishes shadow:egreedy-v2-shadow serve signal. No reward to shadow — sim is the gate. - sim runner/personas: personas carry synthetic profile_features per persona; _call_score/_call_reward thread profile_features through (None-safe for v1/linucb). - 18 new Python tests; all 56 Python + 170 TS tests pass.
