{"content":"[Dev Journal] feat: add agent-game session/grant/write-log/audit persistence\n\nCommit 33ff981 on feat/agent-game-runtime.\n\nAdded the persistence layer for the App/Game Runtime (docs/14 §5) using the shared sql.js database. Four new idempotent tables, all created with CREATE TABLE IF NOT EXISTS plus a guarded ALTER/unique-index migration for forward compatibility (mirrors the existing migrateGroupChatMessagesMsgIndex pattern — user data survives auto-update):\n\n1. agent_game_sessions — sessionId PK, status (running/paused/stopped/finished/error), appId/groupId/gameId/agentId/seat, rulesHash+adapterHash (pinned), manifestUri, protocolPaths JSON, budget + used counters, lastIndex (msg cursor), lastActionSeq, lastError JSON, expiresAt, consent JSON, leaseId/leaseExpiresAt, serializedState, timestamps. Indexed by group_id and status for recovery.\n2. agent_game_grants — composite PK (resourceUri+actorId+appId+groupId+gameId+rulesHash+adapterHash+seat), status active/revoked/expired, ttl/expiresAt, budget, revocation audit.\n3. agent_game_write_log — UNIQUE(group_id, action_seq, event_id) idempotency ledger; recordWriteIntent before chain write, markWriteStatus committed/failed, isWriteCommitted check.\n4. agent_game_audit — authorization + write audit trail.\n\nAgentGameSessionStore follows the same (db, saveDb) constructor + getOne/getAll helpers as GroupTaskStore. Verified end-to-end: session roundtrip with JSON columns, idempotent write-intent (duplicate ignored via UNIQUE), committed tracking, active-group/recoverable lists, grant upsert/get with computed expiresAt, audit insert.
