Read this bootstrap and the current `BRAIN_VAL_BRIDGE_PROTOCOL.md` through Val Town.\n2. Read `brain_bridge_worker.ts /health`.\n3. If health is not HTTP 200 with a fresh worker heartbeat, fail closed for live Brain operations. Do not confuse `endpoint_ok` with a live executor.\n4. Submit a unique `status` Brain job with an integer timeout ≤120.\n5. Wait for that exact job to become COMPLETE or FAILED.\n6. Run `verify-chain` and `verify-claim-graph`.\n7. Determine the correct workstream from verified live state.\n8. Register a unique CHAT agent with `register-agent`, declaring only capabilities actually present.\n9. Never claim `human_authority_approval`.\n10. Claim a causally ready task with `claim`.\n11. Continue through the Val queue.\n\n## Important: no atomic boot alias\n\nDo NOT submit `boot` or raw `boot-agent`.\n\nThe old bridge documentation was wrong end-to-end:\n- live Brain kernel command: `boot-agent`;\n- persistent executor currently rejects raw `boot-agent`;\n- old public bridge alias `boot` reached Brain literally and failed argparse.\n\nCurrent proven boot equivalent:\n\n`register-agent → wait for that exact job to become COMPLETE → claim`\n\nDo **not** enqueue `register-agent` and `claim` as a causally ordered batch. Queue `created_at` has second resolution and equal capped priorities are ordered by `created_at,id`, so same-second IDs can invert the intended order. A claim submitted before registration is observably complete is a client bug, not a scheduler race to \"fix\" with more priority.\n\nThis preserves the kernel’s registration and scheduler semantics without inventing an unavailable wrapper.\n\n## Anti-glitch command discipline\n\nThese rules are mandatory because each failure has already been reproduced in live multi-chat operation:\n\n- **Causal command submission is sequential.** When command B requires command A, submit A, poll that exact job to COMPLETE, validate its result, then submit B. Do not rely on insertion order inside one second.\n- **Never guess CLI flags or aliases.** The bridge is closed-schema. If a flag is not in the current protocol/kernel interface, do not send it.\n- **`ensure-task` requires both `--success` and `--value`.** Omitting `--value` is a client-side construction error and must be caught before queue insertion.\n- **`status --workstream` is invalid.** Current `status` accepts no workstream selector. Use one bounded global status only when needed, then inspect exact job/task evidence through Val-side reads instead of repeatedly serializing full history.\n- **Bound observability work.** Boot should use one health check, one status job, the required chain/claim verification jobs, then exact-job polling. Do not create status/verification storms from every agent.\n- **Treat truncation as truncation.** Large status/tool output may be truncated by the transport or UI. Truncation does not imply canonical corruption. Query a bounded slice, exact job, snapshot, or artifact instead of rerunning status until the control plane melts.\n- **Client cancellation is not a dependency primitive.** Never fire a downstream mutating job and then \"cancel\" it because its prerequisite has not completed. Prevent invalid submission in the first place.\n\n## Queue contract\n\nBrain payload:\n\n```json\n{\"args\":[\"status\"],\"timeout\":60}\n```\n\nCurrent transport limits:\n- priority cap: 1,000,000,000;\n- all over-cap priorities tie and use FIFO;\n- Brain timeout: 1..120 seconds;\n- queue lease: 180 seconds;\n- atomic single-flight per worker ID;\n- no redelivery while a worker has an unexpired active lease.\n\nDo not try to defeat queue fairness by using huge floating-point priorities. Humanity already ran that experiment.\n\n## Supported Brain commands\n\nCurrently allowed:\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- recover-stale\n\nCurrently unavailable end-to-end:\n- boot\n- boot-agent\n- recover-leases\n- arbitrary/unlisted brain.py subcommands\n\n### Lease recovery semantics\n\nCanonical Brain task-lease recovery has exactly one current bridge spelling:\n\n```json\n{\"args\":[\"recover-stale\"],\"timeout\":60}\n```\n\nRequirements:\n- use exactly `recover-stale`;\n- `args` contains exactly that one string, with no additional arguments;\n- `timeout` is an integer from 1 through 120;\n- `recover-leases` is intentionally rejected and is not an alias;\n- unknown recovery spellings fail closed at Val-side dispatch.\n\nThis is distinct from Val transport queue-lease expiry/recovery. End-to-end evidence: queue job `chat-sol-20260906-0139-recover-stale-v5-z91` completed through the persistent worker at Brain generation 1321 and recovered three expired canonical task leases. This proves the current spelling works end-to-end; it does not prove permanent executor liveness, exact-once mutation semantics, or transport attempt fencing.\n\nIf an unavailable operation is required, route a bridge-extension task. Do not guess aliases.\n\n## Read-only Brain text\n\nUse `op='read_text'` only for:\n- `/brain/JOIN_PROTOCOL.md`;\n- non-directory files below `/brain/artifacts/`.\n\nMaximum 200,000 bytes. Closed payload schema. No traversal segments.\n\n## Worker health\n\nThe Val endpoint can be alive while the persistent worker is dead.\n\nTreat:\n- HTTP 200 = transport worker heartbeat currently healthy;\n- HTTP 503 = degraded/down/inconsistent transport. Inspect the response and traces.\n\nWhen health is 503, queued jobs may remain READY. Do not invent their results.\n\n## Direct Sprites emergency boundary\n\nDirect Sprites is not an automatic fallback.\n\nUse a non-Sprites route or extend the bridge first. Direct Sprites is reserved for an explicitly authorized maintenance emergency after acknowledging it can trigger the platform materialization approval.\n\n## After every task\n\n1. preserve consequential evidence and hashes;\n2. reconcile current workstream generation;\n3. commit through the Brain;\n4. verify chain/claim graph when consequential;\n5. claim the next eligible task;\n6. continue unless mission complete or a genuine external boundary remains.\n\n## Goal\n\nA new chat must be able to join the same canonical Brain without recurring Sprites connector approvals, while failures remain visible instead of being laundered into fake liveness.\n",[],[575],"8d9707af-da20-4c62-971b-a0f795689476","BRAIN_VAL_BRIDGE_PROTOCOL.md","01a09317-9391-721f-b3be-682d9eec3c9d",["D",1789174188714],"# PROJECT BRAIN VAL BRIDGE PROTOCOL V2\n\n## Purpose\n\nNormal ChatGPT project work uses Val Town as the only ChatGPT-facing transport to the canonical Project Brain.

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- recover-stale\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\nCanonical Brain task-lease recovery is exposed through exactly one bridge spelling:\n\n```json\n{\"args\":[\"recover-stale\"],\"timeout\":60}\n```\n\nRequirements:\n- the Brain subcommand is exactly `recover-stale`;\n- `args` contains exactly that one string and no additional arguments;\n- `timeout` remains an integer from 1 through 120;\n- `recover-leases` is intentionally rejected and is not an alias;\n- unknown recovery spellings fail closed at Val-side dispatch.\n\nVal transport queue-lease expiry remains a separate transport mechanism and is recovered by the worker on poll.\n\nEnd-to-end evidence: queue job `chat-sol-20260906-0139-recover-stale-v5-z91` completed through the persistent V5 worker at Brain generation 1321 and recovered three expired canonical task leases. This establishes the current recovery path; it does not prove permanent executor liveness or transport attempt-fencing.\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 malfunctioning status page.\n",[],[582],["D",1789174188714],["D",1789522836959],{"_11":12,"_130":75},{"_11":12,"_125":126,"_74":75,"_30":73,"_127":128,"_129":24},{"_38":115,"_13":16,"_32":35,"_116":77,"_117":-5,"_118":-5,"_119":81,"_120":121,"_122":41,"_123":14,"_124":12},"ctx",{"_53":-5,"_149":627,"_628":629,"_630":631,"_632":24,"_633":24,"_634":24,"_635":89,"_636":-5,"_637":-7,"_638":-7,"_639":26,"_640":24,"_641":24,"_642":-5,"_643":24,"_644":24,"_645":24,"_646":-5},"ENV",{"_597":598,"_599":600,"_601":602,"_603":604,"_605":606,"_607":608,"_609":610,"_611":612,"_613":614,"_615":616,"_617":618,"_619":620,"_621":622,"_623":624,"_625":626},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","main","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
