Direct Sprites connector calls are maintenance-only because they can trigger separate file-materialization approval prompts.\n\nNormal path:\n\n`ChatGPT → Val Town → brain_bridge_jobs → persistent Brain worker → canonical Brain`\n\nVal/project: `mosadek/project-brain-live-v1-durable` \nQueue: `brain_bridge_jobs` \nWorker identity: `project-brain-live-v1-worker-v2`\n\n## Mandatory health interpretation\n\nThe HTTP endpoint being reachable is NOT proof that the persistent Brain worker is alive.\n\nRead `brain_bridge_worker.ts /health`.\n\n- HTTP 200 means the most recent worker poll is fresh and the queue has no expired lease or duplicate active lease for one worker ID.\n- HTTP 503 means fail closed. Inspect `worker_state`, `worker_reason`, queue counts, and endpoint traces.\n- `endpoint_ok:true` only proves the Val endpoint itself is executing.\n- `instance_identity_available:false` means the persistent worker has not yet supplied a distinct process instance ID. Do not overclaim process identity.\n\nCurrent Val-side invariants:\n- priority cap: `1_000_000_000`;\n- selection above the cap: FIFO by `created_at,id`;\n- maximum Brain command timeout: `120 seconds`;\n- queue lease: `180 seconds`;\n- atomic single-flight per `worker_id`;\n- an active unexpired lease is not redelivered to another poll sharing that worker ID;\n- a pre-existing duplicate active lease for one worker ID fails closed;\n- expired queue leases are returned to READY on a worker poll;\n- results are accepted only for the current unexpired lease owner.\n\nThese are transport invariants, not Brain authority.\n\n## Submit a Brain command\n\nInsert a unique job:\n\n```sql\nINSERT INTO brain_bridge_jobs\n(id, priority, op, payload_json, state, lease_owner, lease_expires_at,\n result_json, error_json, created_at, updated_at)\nVALUES (?, ?, 'brain', ?, 'READY', NULL, NULL, NULL, NULL,\n datetime('now'), datetime('now'))\n```\n\nBrain payload is closed-schema:\n\n```json\n{\"args\":[\"status\"],\"timeout\":60}\n```\n\nRequirements:\n- exact top-level keys: `args`, `timeout`;\n- `args` is a non-empty string array;\n- `timeout` is an integer from 1 through 120.\n\nCurrently allowed Brain subcommands:\n- status\n- verify-chain\n- verify-claim-graph\n- register-agent\n- ensure-task\n- delegate-task\n- claim\n- renew-lease\n- commit\n- checkpoint\n- add-claim\n- invalidate-claim\n- supersede-task-context\n- migrate-task-invariants\n- reconcile-causal-blocks\n\nAnything else fails at Val-side dispatch rather than being sent onward.\n\n## Boot semantics\n\nThere is currently NO valid atomic `boot` bridge command.\n\nThe public bridge previously advertised `boot`, but the live kernel accepts `boot-agent` while the persistent executor rejects raw `boot-agent`. Therefore neither spelling is a valid end-to-end bridge operation.\n\nUse the proven equivalent sequence:\n\n1. `register-agent`\n2. `claim`\n\nRegister only capabilities actually present in the current chat. Never claim `human_authority_approval`.\n\nExample conceptual sequence:\n\n```text\nregister-agent --workstream --role \n --type CHAT --capabilities \n\nclaim --agent --mode INTERACTIVE --lease-seconds 1800\n```\n\nDo not submit `boot` or `boot-agent` until a later verified bridge/executor revision explicitly restores an atomic wrapper.\n\n## Lease recovery semantics\n\nDo not submit `recover-leases` or `recover-stale` through this bridge revision.\n\n- Val transport queue lease expiry is recovered automatically by the worker on poll.\n- Canonical Brain task-lease recovery is a separate operation and is not currently exposed end-to-end by the persistent executor.\n- If canonical stale-lease recovery becomes necessary, create/route a bridge-extension task or use another verified non-Sprites route. Do not guess an alias.\n\n## Poll a job result\n\n```sql\nSELECT id,state,lease_owner,lease_expires_at,result_json,error_json,updated_at\nFROM brain_bridge_jobs\nWHERE id=?\n```\n\nTerminal states:\n- COMPLETE\n- FAILED\n\nA READY job means it has not been executed. A LEASED job is not complete. Do not infer canonical mutation from queue state alone.\n\n## Read Brain text without Sprites\n\nUse `op='read_text'` with exact closed-schema payload:\n\n```json\n{\"path\":\"/brain/JOIN_PROTOCOL.md\",\"max_bytes\":200000}\n```\n\nAllowed paths:\n- exactly `/brain/JOIN_PROTOCOL.md`;\n- a non-directory file strictly below `/brain/artifacts/`.\n\nConstraints:\n- `max_bytes`: integer 1..200000;\n- no `.` or `..` path segments;\n- no backslash or NUL;\n- no extra payload fields.\n\nEarlier worker stalls coincided with read jobs, but later bounded artifact reads completed successfully. Therefore do not claim that `read_text` itself caused the historical stall. Keep the bounded allowlist and use current worker health as the liveness signal.\n\n## Hard transport rule\n\nRoutine ChatGPT work:\n- DO NOT call Sprites;\n- DO NOT call Sprites.exec;\n- DO NOT call Sprites.file_read/file_write/file_copy/file_delete;\n- DO NOT call Sprites service/checkpoint/file/blob operations.\n\nIf a required operation is missing:\n1. use an existing valid non-Sprites substrate when possible;\n2. route or build a bridge extension;\n3. fail closed if the missing operation is necessary;\n4. direct Sprites remains an explicit maintenance emergency, not an automatic fallback.\n\n## Failure behavior\n\nIf jobs stay READY:\n1. inspect `/health`;\n2. inspect worker endpoint traces;\n3. inspect the current active/expired queue leases;\n4. do not raise transport priorities above the cap to win a queue arms race;\n5. do not interpret the Val endpoint being online as the Brain worker being online.\n\nIf worker health is DOWN:\n- queued commands remain pending;\n- no live Brain registration, claim, commit, status, or verification should be invented;\n- Val-side code/evidence work may continue when it does not pretend to mutate canonical Brain;\n- repair/restore the persistent executor through an authorized route, then resume queue processing.\n\n## Proven facts and bounded claims\n\nThe reverse bridge has successfully:\n- read Brain status;\n- created canonical Brain tasks;\n- registered CHAT agents;\n- claimed tasks;\n- committed task results;\n- run verify-chain and verify-claim-graph.\n\nThe Val-side worker has independently reproduced and repaired the same-worker concurrent lease race in isolated queue tests. This does NOT prove the persistent Sprite-side executor is permanently supervised or continuously alive.\n\n## Goal\n\nNormal project work must stay materialization-free from ChatGPT while remaining fail-closed:\n\n`ChatGPT agent → Val Town → durable queue → live worker → verified Brain`\n\nIf the live worker disappears, the system must say so rather than smiling with HTTP 200 like a
