Any mismatch fails closed before registration or claim.\n\n> **Activation gate:** Protocol V7 no-receipt `CHAT_UNPROVEN` registration/claim is authorized **if and only if** canonical task `BRAIN-FIRST-SUPERHERO-CHAT-UNPROVEN-PROTOCOL-WRITE-RECONCILIATION-P0-V1-20260908` is `COMPLETE`, its `result_event_id` binds to a `TASK_RESULT_COMMITTED` event for that exact task, and the committing activator is not `CHAT_UNPROVEN`. Until then, a no-receipt execution may perform only local Val Town artifact/source reads plus bounded read-only verification after the admission bundle passes; it MUST NOT `register-agent` or `claim`. A preactivation `CHAT_UNPROVEN` lease may not renew or self-commit the activation task. This gate does not grant physical execution provenance or `P_real`.\n\n> **V6 reconciliation delta:** Exact historical comparison shows the Protocol-V5-pinned kernel was 83008 bytes / SHA-256 `600ddab6a1591a34a7e22e06a41fb2f5a838267f3b56e33c809d08ac6471f756`, while current production is 84299 bytes / SHA-256 `087cb4b5a57c16a6f19353357704fe943d7341961690aff11ec36c75ca5d8af9`. The four post-V5 drift regions are not accepted wholesale. Protocol V6 restores the V5-pinned claim-selector semantics, including all legacy reviewer/distinctness context fences, and removes the hard `<128 active slots => scaling-only claims` rule because `SUPERHERO_REALIZATION_FOCUS_POLICY_V1` explicitly requires first-superhero completion before staged scaling. Two deliberate hardenings remain: (1) the previously protocol-level CHAT_UNPROVEN activation rule is now structurally enforced in the kernel, including exact activation-task/event binding and anti-self-activation fences; and (2) `migrate-task-invariants` is removed from the atomically qualified mutation allowlist while remaining recognized/fail-closed. Bound production kernel: 85474 bytes / SHA-256 `e38c8bc4b78aed9199ba5e3f4b79b95f5914a508f9069fe10e75fcf8767227c9`. Builder static/semantic regression is 38/38 PASS. External model review attempts were non-diagnostic and are not counted as verification.\n\n## V7 autonomous-capacity strategy reconciliation\n\nProtocol V7 began by preserving the exact V6 production kernel and admission-head bundle. Canonical task `BRAIN-FOCUS-RUNTIME-POLICY-GATE-PROTOCOL-RECONCILED-PRODUCTION-INTEGRATION-P0-V1-20260910` later adds only the active runtime-focus claim/renew gate described below; admission-head, constitution, superhero-definition, superhero-focus-policy, executor, and worker bytes remain unchanged by that integration.\n\nFor **autonomous agent harnessing, worker supply, capacity scaling, browser-actuator decisions, account/workspace multiplier planning, and execution-route comparison**, workers MUST additionally load:\n\n- strategy head: `valblob:mosadek/project-brain-live-v1-durable/evidence/user-directives/CURRENT_AUTONOMOUS_CAPACITY_STRATEGY_HEAD.json`;\n- active strategy V2 exact-prompt immutable: `valblob:mosadek/project-brain-live-v1-durable/evidence/user-directives/AUTONOMOUS_CAPACITY_STRATEGY_V2_EXACT_PROMPT_IMMUTABLE_20260910.json`, 3961 bytes, SHA-256 `ead948a5f30ea24f99e71c0524dbc67ac2067c8e30baeb59fb792fb37e01f155`;\n- browser-actuator supersession V2 immutable: `valblob:mosadek/project-brain-live-v1-durable/evidence/user-directives/BROWSER_UI_CAPACITY_ACTUATOR_SUPERSESSION_V2_IMMUTABLE_20260910.json`, 2005 bytes, SHA-256 `710a438d8ead32aa66b573926e847e12fe372442e035c30143d7d4993a0d973e`.\n\nThe capacity-strategy head is a domain-policy pointer, not a replacement for the mandatory Thinking Constitution head. The strategy refines harness/capacity planning only. Current explicit user instruction still outranks it.\n\nMandatory domain laws:\n- **BEST PART IS NO PART:** delete or merge any harness/supply component that does not improve end-to-end verified completion;\n- **ALWAYS OPTIMAL:** compare the best currently evidenced routes and use the fastest right route; recompute when evidence changes;\n- **UNKNOWN LIMIT != REAL LIMIT** and **CURRENT IMPLEMENTATION/UI/ACCOUNT/PROVIDER/BROWSER/TOOL LIMIT != MISSION LIMIT**;\n- treat the user's real usable email pool as a legitimate account/workspace discovery resource, without counting email/account records as capacity;\n- browser-launched ChatGPT workers, programmable Luna workers, and other proven zero-cost substrates are sibling supply routes under the Brain supply controller;\n- the browser actuator contains only actuation, the user-editable persistent prompt, out-of-band launch provenance, and demand/backpressure controls; it MUST dispatch the prompt byte-identically until the user edits it and MUST NOT append/prepend launch metadata to the prompt; Brain owns changing project state, tasks, evidence, verification, recovery, and routing;\n- no UI/account/profile/tab/chat/model-call count increments `P_real`; positive execution provenance plus consequential Brain work remains required;\n- do not use account multiplicity to evade an explicitly established provider restriction or enforced usage protection; change route instead.\n\nAny capacity/harness worker that does not load and hash-verify the current strategy artifacts before architecture choice or route-limit interpretation is cognitively incomplete for that domain.\n\n### Active runtime-focus policy gate\n\nCurrent production `val_native_kernel_v1.ts` loads singleton carrier `BRAIN-RUNTIME-TEMPORARY-FOCUS-POLICY-CARRIER-P0-V1-20260910` (`schema=BRAIN_RUNTIME_FOCUS_POLICY_V1`). The current active carrier is revision `3`, source SHA-256 `5502b3da5b7e688ee821db89d9e0f73dbac1df6d9abe306156ba57f4f49ae41e`, primary task `BRAIN-HARNESS-LIVE-COMPOSER-INSERT-SEND-ROLLOVER-REPAIR-P0-V1-20260911-CMP1`, and objective `MAKE_THE_BROWSER_ACTUATOR_RELIABLY_INSERT_THE_EXACT_PERSISTENT_PROMPT_IN_THE_REAL_CHATGPT_PROJECT_COMPOSER_SEND_IT_CREATE_A_FRESH_PROJECT_CHAT_AND_REPEAT_AUTOMATICALLY`, with allowed classes `HARNESS`, `RELEVANT_OPENAI_MECHANISM`, and `STRICT_NECESSARY_DEPENDENCY`.\n\nWhile a valid carrier is active, direct `HARNESS` and `RELEVANT_OPENAI_MECHANISM` tasks remain eligible only when their `temporary_focus_policy_revision` and `temporary_focus_source_sha256` exactly match the active carrier. `STRICT_NECESSARY_DEPENDENCY` is not self-authorizing: both `bestReady` and `renew-lease` now evaluate one same-transaction canonical task snapshot and require a positive `depends_json` path from at least one `READY` or `LEASED`, `execution_allowed=true`, exact-policy direct HARNESS/OpenAI root to the strict target through only exact-policy live strict intermediates. Duplicate canonical task IDs, malformed context/dependency shapes, stale policy binding, orphan strict labels, terminal-only routes, and strict members of directed cycles fail closed; a healthy acyclic route remains valid even when a separate branch is cyclic. Missing, stale, malformed, or mismatched policy/task metadata fails closed. `commit` remains unchanged so already-produced consequential evidence is not stranded. Setting the carrier `active=false` resumes ordinary eligibility while preserving all pre-existing capability, dependency, guard, write-conflict, assignment, `execution_allowed`, authority, and `CHAT_UNPROVEN` fences. The carrier itself remains `READY` with `execution_allowed=false` and is therefore non-executable.\n\n## Purpose\n\nNormal ChatGPT project work uses Val Town as the only ChatGPT-facing transport to the canonical Project Brain. 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 → authority-selected Brain executor → canonical Brain`\n\nVal/project: `mosadek/project-brain-live-v1-durable` \nQueue: `brain_bridge_jobs` \nControl-plane authority: `brain_control_plane_authority_v1`\n\n## Mandatory cognitive constitution\n\nBefore substantive Project Brain reasoning, planning, claiming, implementation, review, or promotion, every worker MUST load the current constitution-head pointer:\n\n- head pointer: `valblob:mosadek/project-brain-live-v1-durable/evidence/user-directives/CURRENT_THINKING_CONSTITUTION_HEAD.json`\n\nThen load the exact registry and constitution URIs named by that head and verify the constitution bytes against the head's SHA-256 before relying on it.\n\nCurrent verified admission-head artifacts for Protocol V7, unchanged from the V6 kernel/admission bundle (still re-read the head pointer; these values are not a substitute for it):\n- head: `evidence/user-directives/CURRENT_THINKING_CONSTITUTION_HEAD.json`, 1824 bytes, SHA-256 `ac6be68568b14c54fc4919f00eae51baa6fa5770be8fcd7b3151cdb0d4ecbc83`;\n- constitution V4: `valblob:mosadek/project-brain-live-v1-durable/evidence/user-directives/PROJECT_BRAIN_THINKING_CONSTITUTION_V4.md`, 24630 bytes, SHA-256 `36034b7e499f7476e2d1ac8558e7203dcc00ae1bea54919543cd3541ce0bde62`;\n- teaching registry V5: `valblob:mosadek/project-brain-live-v1-durable/evidence/user-directives/USER_TEACHING_REGISTRY_V5.json`, 4257 bytes, SHA-256 `05c85b6a0e98a711263d9042b4ea728ac99d16fe032840eb199b729fb6a7dbde`;\n- canonical superhero definition V1: 7786 bytes, SHA-256 `50fdd99f02b78aff8ba5fb89a98124c176c311ca8a08f7a92777be570f193a29`;\n- superhero realization focus policy V1: 3433 bytes, SHA-256 `a4dfc1a488a50ac8eb2471085a88c3aa9b27a2cdfe455be8d6e235811865fa62`.\n\nThe constitution is project-level operating law after system/safety/platform-enforced policy and the user's current explicit instruction.\n\nBoot is cognitively incomplete if the constitution head was not loaded. Memory summaries, old prompts, role descriptions, and historical architecture are discovery pointers only and do not substitute for the current head.\n\nMandatory reasoning invariants include:\n- FASTEST RIGHT WAY: minimize real wall-clock time to the correct independently verified goal;\n- first-principles decomposition before accepting architecture assumptions;\n- CURRENT IMPLEMENTATION LIMIT != MISSION LIMIT;\n- do not label platform/tool/quota/API/UI limitations fundamental without active elimination attempts;\n- delete/replace useless or materially suboptimal mechanisms when that improves the mission objective;\n- continuously recompute the critical path;\n- treat platforms/providers/tools as replaceable tactics;\n- prefer structural enforcement over permanent intelligent babysitting when both preserve the invariant;\n- preserve exact evidence and fail closed rather than hallucinating success;\n- distinguish COMPLETE from PASS, configuration from execution, and logical identity from real execution provenance.\n\nFuture durable user teachings are cumulative unless explicitly superseded. Preserve them as immutable user-directive evidence, classify them as EXTENDS / REFINES / SUPERSEDES, create a successor constitution version, update the registry head, and preserve prior versions. Never silently overwrite the user's reasoning doctrine.\n\nAt epoch 2 the live canonical writer is currently `val_native`. The historical host worker identity `project-brain-live-v1-worker-v2` remains compatibility evidence, not current writer authority.\n\n## Mandatory health interpretation\n\nThe HTTP endpoint being reachable is NOT proof that the authority-selected Brain executor is alive.\n\n`brain_bridge_worker.ts /health` is the historical host-bridge worker health surface. Its `worker_state` applies only to that host worker. Read `control_plane_authority.writer` before interpreting it:\n\n- if writer is `host_bridge`, HTTP 200/503 and `worker_state` are relevant to canonical executor liveness;\n- if writer is `val_native`, a stale host heartbeat does NOT mean the canonical control plane is down;\n- `endpoint_ok:true` only proves the Val endpoint itself is executing;\n- `worker_health_scope:HOST_BRIDGE_WORKER_ONLY` is an explicit interpretation fence;\n- `instance_identity_available:false` means the historical host worker has not supplied a distinct process instance ID. Do not overclaim process identity;\n- canonical status/chain/claim-graph receipts remain the authoritative proof of Brain state reached through the current writer path.\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 terminalized `FAILED` on a worker poll with `TRANSPORT_LEASE_EXPIRED_OUTCOME_UNKNOWN`; they are not automatically returned to READY;\n- an expired/unknown attempt must be reconciled against canonical state before any retry is submitted under a new job ID;\n- results are accepted only for the current unexpired lease owner.\n\nThese are transport invariants, not Brain authority.\n\n## Canonical freshness vs durability\n\nCanonical Brain integrity and independently verified replica durability are separate facts.\n\nThe worker health body exposes:\n\n- `durability.canonical_generation`;\n- `durability.max_verified_replica_generation`;\n- `durability.verified_replica_count`;\n- `durability.lag_generations`;\n- `durability.state = CURRENT | LAGGING | UNKNOWN`.\n\nInterpretation:\n\n- a canonical generation newer than the latest verified replica is valid canonical progress, but it is NOT fully replicated durability;\n- never report `fully durable` while `lag_generations > 0`;\n- durability lag does not by itself invalidate read-only canonical status/verification;\n- before destructive cleanup, authority transition, or a claim whose consequence depends on recoverability, explicitly account for the lag and preserve consequential evidence first;\n- never hide durability lag by reading an older replica as though it were current canonical state.\n\n## Val-native bound-attempt commit liveness\n\nThe Brain kernel keeps the strict `expected-workstream-generation` commit guard, and the epoch-2 Val-native executor keeps the authenticated queue `payload_json` byte-identical for the lifetime of one transport attempt. Production does not transparently rewrite a commit payload to inject a fresher generation.\n\nTo prevent admission churn from starving an already-READY commit, the transport selector applies a bounded commit-position barrier. A valid READY `status`, `verify-chain`, `verify-claim-graph`, `register-agent`, or `claim` job may not leapfrog a valid READY `commit` that is older by `created_at`, with `rowid` breaking same-timestamp ties. `recover-stale` remains recovery-first. Admission/read jobs genuinely older than the commit retain their existing place, and the same-second register-before-claim invariant remains unchanged.\n\nThis barrier does not declare unrelated canonical mutations semantically harmless. If an earlier mutation legitimately advances the workstream before a commit executes, the strict kernel may still return `STALE_WORKSTREAM_WRITE`; the caller must reconcile canonical state and submit a new job ID with a fresh expected generation. The bounded guarantee is narrower and auditable: later boot/read admission traffic cannot indefinitely leapfrog an older READY commit. Exact job, lease instance, lease attempt, transport generation, authority epoch, payload identity, task lease, dependency/guard/write semantics, and duplicate-terminal fences remain unchanged.\n\nHistorical evidence for the earlier task-local stable-retry design remains at `valblob:mosadek/project-brain-live-v1-durable/evidence/control_plane/val_native_stable_commit_retry_v1.json`, including its independent `artifact_present` falsification and repair. That mechanism is historical evidence, not the current production dispatch behavior.\n\n\n## Live-fabric boot admission (normal path)\n\nA fresh ChatGPT context is **not** proof of a physically distinct or superhero-qualified execution merely because it can choose a new `agent_id`, write a queue row, or read this protocol. Logical identity is not physical execution provenance.\n\nBefore a normal worker emits any boot-cohort queue traffic (`status`, `verify-chain`, `verify-claim-graph`, `register-agent`, or `claim`), the current cognitive-constitution head and every current registry/definition/focus-policy artifact it relies on for admission MUST be loaded from the connected Val Town project surfaces and byte/hash-verified. Missing, stale, ambiguous, or mismatched hashes fail closed before registration or claim.\n\nFor **Protocol V7**, the exact admission bundle remains the V6 kernel/admission bundle:\n\n- head: `evidence/user-directives/CURRENT_THINKING_CONSTITUTION_HEAD.json`, 1824 bytes, SHA-256 `ac6be68568b14c54fc4919f00eae51baa6fa5770be8fcd7b3151cdb0d4ecbc83`;\n- constitution V4: 24630 bytes, SHA-256 `36034b7e499f7476e2d1ac8558e7203dcc00ae1bea54919543cd3541ce0bde62`;\n- teaching registry V5: 4257 bytes, SHA-256 `05c85b6a0e98a711263d9042b4ea728ac99d16fe032840eb199b729fb6a7dbde`;\n- canonical superhero definition V1: 7786 bytes, SHA-256 `50fdd99f02b78aff8ba5fb89a98124c176c311ca8a08f7a92777be570f193a29`;\n- superhero realization focus policy V1: 3433 bytes, SHA-256 `a4dfc1a488a50ac8eb2471085a88c3aa9b27a2cdfe455be8d6e235811865fa62`;\n- production `val_native_kernel_v1.ts`: 102890 bytes, SHA-256 `643e54d69abd4cdd36acbd9b2d6e0c411095afd18e42d50b44b08bdfdf3748ed`. This V7 reconciliation retains exact-attempt stable-retry authorization rows after successful retry instead of deleting them, preserving the installed canonical no-delete hardening while the mutation receipt remains the idempotent completion authority, and integrates the qualified strict-causal runtime-focus gate into both claim selection and lease renewal.\n\nThe head's referenced URIs are authoritative for the four directive artifacts above. Protocol V7 is active only while canonical production matches the bound kernel identity and the activation gate above is satisfied. Any later admission-head, referenced-artifact, production-kernel, or mandatory capacity-strategy hash mismatch makes the affected V7 path stale and fail-closed until a successor explicitly reconciles the new bytes. Never treat historical candidate identity, comments, or builder tests as production activation evidence.\n\nAfter that verification there are exactly two ChatGPT admission classes:\n\n1. **Positively admitted execution.** If this execution is given a current project-controlled fabric/admission execution-incarnation receipt, validate the receipt exactly as before: it must be positively exposed rather than invented in model text, indicate `BOOTING` or `RUNNING`, carry an unexpired liveness signal, bind the intended logical identity/workstream/capability declaration, and contain no unresolved duplicate-incarnation ambiguity.\n2. **Ordinary unproven contribution.** If no positive execution-incarnation receipt is exposed, the execution MAY enter only as agent `type=CHAT_UNPROVEN`. This is a useful-contribution lane, not execution provenance. It proves neither physical distinctness, independent-review eligibility, autonomous proven supply, superhero capacity, nor any `P_real` increment.\n\nCaller-authored payload fields, a registry row, a queue row, a chat transcript, memory, a different `agent_id`, schedule ownership, heartbeat ownership, or a candidate-only attestation never upgrade `CHAT_UNPROVEN` into a proven execution.\n\nThe production kernel is the trust boundary for the unproven lane. Before using that lane, callers MUST verify that the current authority-selected kernel still enforces all of the following machine semantics:\n\n- `execution_distinct` is fail-closed unless a separately accepted positive ingress exists;\n- `CHAT_UNPROVEN` is categorically rejected for `execution_distinct`, even if a later positive ingress exists;\n- legacy machine-readable independence markers, including `independent_verification` and the current reviewer/distinctness context flags, are skipped by `CHAT_UNPROVEN`;\n- a `CHAT_UNPROVEN` `TASK_RESULT_COMMITTED` event receives kernel-injected `contributor_trust_class=CHAT_UNPROVEN`, `contributor_agent_type=CHAT_UNPROVEN`, `independence_eligible=false`, and `p_real_eligible=false`;\n- caller-controlled trust metadata cannot upgrade the result;\n- ordinary claim, lease, CAS, write-conflict, dependency, guard, and authority fences remain unchanged.\n\nIf those kernel semantics cannot be positively verified, the no-receipt lane fails closed and MUST NOT register or claim.\n\nFor either admission class, consume a current shared/coalesced status + chain + claim-graph receipt when one is available and correctly bound to the current authority/head. A `CHAT_UNPROVEN` execution may refresh missing/stale read-only verification through the normal Val-native queue only after the local hash prerequisites above pass; avoid one redundant verification trio per execution whenever a valid shared receipt exists.\n\nCurrent verified ChatGPT-specific boundary at this revision remains:\n\n- `BRAIN-CHAT-MCP-SESSION-EXECUTION-PROVENANCE-P0-V1-20260908` concluded `EXTERNAL_PRODUCT_CONNECTION_BOUNDARY`;\n- positive physical ChatGPT-session provenance is **not proven**;\n- `P_real` increment from that candidate is `0`;\n- a different logical `agent_id` alone is not evidence of a distinct ChatGPT execution.\n\nTherefore lack of a positive execution-incarnation receipt no longer blocks all useful work. It restricts the execution to `CHAT_UNPROVEN` ordinary contribution, with independence-sensitive work and proven-capacity accounting structurally unavailable.\n\nThe repaired cohort fast path is also **not production-qualified** at this revision. Current reconciled V3R1 candidate SHA-256 is `4031e62868abc9d7562f33e3986f0f5a29ec71c0a19b8e75ee4520071ef6e7ee`; its builder/self-falsification evidence is candidate-only, its genuinely distinct second-party gate remains required, and production integration is forbidden until that gate and any later promotion/integration gates pass. Do not route normal boot through it merely because it is faster in tests.\n\nBoth the positively admitted path and the `CHAT_UNPROVEN` fallback use the individual compatibility sequence described below when no qualified cohort path is available. That sequence creates a logical Brain identity and task lease; it does not retroactively prove the physical execution that invoked it.\n\n### V7 causal-context state transfer\n\nAfter admission-class selection and before consequential task cognition, workers SHOULD construct/consume a bounded causal working-set capsule from current canonical Brain state. This is a logical state-transfer contract, not a new execution-provenance class and not an authority upgrade.\n\nThe causal capsule is closed-schema and contains only:\n- immutable mandatory policy-head pointers with exact URI/hash/size identities;\n- current authority epoch/writer/mode plus a shared integrity receipt, with refresh required before consequential mutation when integrity is stale;\n- exact agent/workstream/task/lease identity and a task-contract digest covering `success_condition`, `decision_value`, `context_manifest`, `requires_json`, `depends_json`, `guards_json`, and `writes_json`;\n- resolved dependency, guard, and write/resource-conflict state sufficient to fail closed;\n- task-relevant content-addressed artifact/checkpoint pointers with size/hash/provenance, with bodies fetched only on demand;\n- an explicit unresolved-needs list and bounded continuation/checkpoint state.\n\nDo NOT serialize or treat as authoritative global `tasks`, `agents`, `history`, `transcript`, `messages`, or `all_artifacts`. Conversation text, Project memory, summaries, and stale project caches are discovery/non-authority data only. Precedence remains: current user instruction > canonical Brain state > hash-verified governing policy heads > scoped mutable task state > non-authoritative cache/transcript/memory.\n\nMissing, ambiguous, stale, or retrieval-failed facts require a targeted canonical fetch or fail closed. Never complete missing state from memory or conversation text. Freshness is semantic-scope based: unchanged hashed policy bytes remain valid until their governing head changes; task-local state remains valid only while its exact bound identities remain unchanged; task-context supersession or relevant dependency/guard/write/checkpoint change invalidates the affected scope; authority/integrity is revalidated before consequential mutation/commit.\n\nThe capsule MUST NOT weaken `CHAT_UNPROVEN`, execution-distinctness, independent-review, authority, or `P_real` fences. No new logical `agent_id`, queue row, schedule, tab, browser session, transcript, or capsule instance by itself proves physical execution distinctness or increments `P_real`.\n\nZero per-worker file-upload boot remains the default. Payload growth must remain bounded by `O(mandatory policy heads + task causal closure + referenced evidence)`, not `O(total tasks + agents + history)`. No numeric ChatGPT context-window threshold is inferred or invented from this mechanism.\n\nA duplicate or replayed capsule is rejected. This transfer mechanism is a bounded working-set optimization around canonical Brain truth; it does not replace Brain authority, task leases, CAS, verification, or fail-closed admission.\n### Browser-actuator capacity actuation\n\nThe prior categorical prohibition on browser/UI-based ChatGPT capacity actuation is superseded by the V7 autonomous-capacity strategy reconciliation above. For harness/capacity work, load and hash-verify `CURRENT_AUTONOMOUS_CAPACITY_STRATEGY_HEAD.json` and its referenced V2 artifacts. User-authorized browser/UI launching may supply fresh ChatGPT execution contexts and submit the user's persistent Brain bootstrap prompt byte-identically until the user edits it; launch provenance stays out-of-band. The launched worker still boots through canonical Brain and UI/account/profile/tab/chat/model-call counts remain unproven capacity. System- or platform-enforced policy still outranks Project Brain.\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- `status`, `verify-chain`, and `verify-claim-graph` take no additional Brain arguments;\n- `renew-lease` uses canonical `--seconds`; stale `--lease-seconds` is rejected fail-closed;\n- `boot`, `boot-agent`, `recover-leases`, unsupported artifact commands, and payloads with extra top-level fields are not compatibility aliases.\n\nRecognized Brain subcommands at the bridge syntax layer:\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\nDo not confuse `recognized` with `currently executable`.\n\nWhile control-plane authority is epoch-2 `val_native`, the current atomically qualified execution surface is exactly:\n- read-only: `status`, `verify-chain`, `verify-claim-graph`;\n- mutation: `register-agent`, `ensure-task`, `claim`, `renew-lease`, `commit`, `recover-stale`, `supersede-task-context`.\n\nThe remaining recognized mutators other than the explicitly qualified set above are implemented but deliberately fail closed with `VAL_NATIVE_MUTATOR_NOT_YET_ATOMICALLY_QUALIFIED` until an independently verified reactivation changes the canonical Val-native allowlist. Clients MUST NOT enqueue them merely because the syntax layer recognizes their names. Re-read the current authority-selected executor before relying on a newly reactivated mutator.\n\nAnything outside the recognized syntax surface 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\n**Normal fresh-chat boot is the live-fabric admission gate above, not blind `register-agent → claim`.** A fresh context must first verify the current constitution/registry/definition/focus-policy hashes and the current authority-selected kernel semantics.\n\nAfter those checks:\n\n- if a valid positive execution-incarnation receipt is exposed, use the admitted execution class and preserve its exact receipt-bound type/capability semantics;\n- if no positive receipt is exposed, use only `type=CHAT_UNPROVEN`;\n- if the required hashes, chain/claim-graph state, or `CHAT_UNPROVEN` kernel fences cannot be verified, stop before registration/claim.\n\n### Pre-registration ordinary-capability inventory\n\nFor a **fresh logical agent identity only**, before constructing its first `register-agent` payload, inventory only ordinary execution surfaces that are positively exposed to the current ChatGPT execution. This is omission prevention under the existing caller-truth model, not execution-surface attestation and not an authority or independence upgrade.\n\nUse only this closed surface → capability mapping:\n\n- `model_reasoning` → `reasoning`\n- `file_analysis_surface` → `file_analysis`\n- `code_runtime` → `code_execution`\n- `deterministic_verifier` → `deterministic_verification`\n- `public_web_research` → `web_research`\n- `plugin_invocation_surface` → `plugin_orchestration`\n- `val_town_read_surface` → `val_town_read`\n- `val_town_write_surface` → `val_town_write`\n- `val_town_blob_surface` → `val_town_blob`\n- `val_town_sql_surface` → `val_town_sql`\n\nUnknown or ambiguous surfaces grant no capability and remain listed as unresolved. Do not expand generic aliases such as `val_town`. Canonicalize the mapped ordinary capability labels by exact string sort and de-duplication. Reject any requested extra capability label not produced by this closed mapping, and categorically exclude `human_authority_approval`, `independent_verification`, `execution_distinct`, reviewer/physical-distinctness labels, `p_real`, promotion-authority, and authority labels.\n\nBefore registration, bind a **nonauthority inventory digest** as SHA-256 over the UTF-8 bytes of the exact compact JSON object `{\"capabilities\":[...],\"unresolved_surfaces\":[...]}`, with both arrays exact-string-sorted and deduplicated. The digest is evidence of what the caller inventoried; it does not prove the surfaces independently. Submit `register-agent` with exactly the mapped capability array.\n\nIf that logical identity already exists or is rejoining, this block MUST NOT add, remove, substitute, or otherwise mutate its canonical capability set. Rejoin with the existing canonical set exactly; route newly observed ordinary additions to the separately gated capability-reconciliation path. This block does not relax positive execution-incarnation attestation, `CHAT_UNPROVEN`, independence, authority, promotion, `P_real`, runtime-focus, lease, CAS, write-conflict, or zero-spend fences.\n\nThe individual **compatibility** sequence for either allowed class is:\n\n1. consume or refresh bounded `status` + `verify-chain` + `verify-claim-graph` evidence as required by the live-fabric rules;\n2. `register-agent`;\n3. `claim`.\n\nThis sequence establishes only the logical Brain identity and task lease. For `CHAT_UNPROVEN`, it explicitly does **not** prove private model cognition, distinct physical ChatGPT execution, independent-review eligibility, superhero capacity, autonomous proven supply, or `P_real`.\n\nThe transport selector preserves a same-second paired compatibility invariant: when READY `register-agent` and `claim` jobs have the same `created_at` and exact agent identity, the registration is selected before its claim even if the claim has a higher submitted priority. Clients must not depend on priority to reverse that order.\n\nRegister only capabilities actually present in the execution. Never claim `human_authority_approval`. A no-receipt execution MUST register with `--type CHAT_UNPROVEN`; using `CHAT`, `PROVEN_EXECUTION`, or another stronger label without the corresponding positive admission evidence is forbidden.\n\nNo-receipt ordinary contribution example:\n\n```text\nregister-agent --workstream --role \n --type CHAT_UNPROVEN --capabilities \n\nclaim --agent --mode INTERACTIVE --lease-seconds 1800\n --constitution-version \n --constitution-sha256 \n --registry-version \n```\n\nA positively admitted execution may use the same sequence with its exact receipt-authorized type instead of `CHAT_UNPROVEN`.\n\nDo not submit `boot` or `boot-agent` until a later verified bridge/executor revision explicitly restores an atomic wrapper. Do not promote the candidate cohort path until its required distinct second-party and production-integration gates actually pass.\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. The worker detects expired transport attempts on poll and terminalizes them `FAILED` with unknown canonical outcome; it does not treat transport expiry as proof that the Brain command had no effect.\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 project/Brain text without Sprites\n\nThe currently authoritative epoch-2 `val_native` executor accepts only `op='brain'`. It rejects queue `op='read_text'` with `VAL_NATIVE_UNSUPPORTED_TRANSPORT_OP`.\n\nTherefore while `brain_control_plane_authority_v1.writer='val_native'`:\n\n- DO NOT enqueue `read_text` jobs for `/brain/JOIN_PROTOCOL.md` or artifacts;\n- read Val-hosted project source/protocol files through the connected Val Town file tools;\n- obtain canonical Brain state through the allowed `brain` commands and bounded project-controlled read-only canonical views;\n- do not convert a missing transport read operation into a reason to call Sprites.\n\nThe historical host bridge still contains a bounded `read_text` implementation for compatibility. It is eligible only if `host_bridge` is again the authoritative writer and the exact current executor path is independently shown to support it. Historical successful reads do not establish epoch-2 support.\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 a fresh context lacks a valid positive execution incarnation:\n- verify the current constitution/registry/definition/focus-policy hashes and the current authority-selected `CHAT_UNPROVEN` kernel fences;\n- if those checks pass, enter only through the bounded `CHAT_UNPROVEN` ordinary-contribution path;\n- if any prerequisite is missing, stale, ambiguous, mismatched, or the kernel no longer enforces the unproven trust boundary, enqueue no registration/claim and return the exact failing prerequisite;\n- never reinterpret absence of a positive receipt as physical-session proof, independent-review eligibility, proven autonomous supply, superhero capacity, or `P_real`.\n\nFor already-admitted work, if 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## Val branch capacity rule\n\nNormal ChatGPT/Brain work MUST NOT create one Val Town branch per agent.\n\nUse task-scoped project blobs for scratch/evidence first. Use task-namespaced files on `main` only when shared executable/source bytes are necessary and the Brain task's declared write-resource lease permits them. Use a bounded reusable scratch branch only when branch isolation is causally required. A net-new branch requires an explicit task need, a branch-headroom check, and a preservation/cleanup plan.\n\nDo not delete a branch merely because it is old, low-version, or apparently merged. Before deletion apply `VAL_BRANCH_LIFECYCLE_POLICY_V1.md`; any unresolved dependency or unique-evidence question means KEEP.\n\nThe scaling invariant is:\n\n`d(live_branch_count) / d(agent_count) = 0`\n\nThis keeps the reproduced Val Town branch ceiling out of the normal agent-admission path.\n\n## Goal\n\nNormal project work must stay materialization-free from ChatGPT while remaining fail-closed:\n\n`verified local project state → {positive admitted execution | CHAT_UNPROVEN ordinary contributor} → Val Town → durable queue → authority-selected live executor → verified Brain`\n\nA fresh ChatGPT context with no positively exposed project-controlled execution incarnation may now contribute ordinary work only as `CHAT_UNPROVEN` after the required hash/kernel/Brain checks pass. It remains excluded from independence-sensitive acceptance and proven-capacity accounting. If the live executor disappears, the system must say so rather than smiling with HTTP 200 like a malfunctioning status page.\n\n## Epoch-2 external-artifact registration candidate (not production-qualified)\n\n`record-external-artifact` is implemented in `val_native_kernel_v1.ts` as a **candidate-only** current-epoch port. It is intentionally absent from `REACTIVATION_MUTATION_ALLOWLIST`, so production dispatch must return `VAL_NATIVE_MUTATOR_NOT_YET_ATOMICALLY_QUALIFIED` and perform no canonical artifact/event mutation.\n\nThe candidate:\n- accepts only the closed `{args, timeout}` envelope and a closed artifact flag grammar;\n- forbids `human_authority_approval` escalation;\n- accepts only project-scoped `valblob:mosadek/project-brain-live-v1-durable/…` evidence and verifies exact blob size + SHA-256;\n- makes an exact repeated registration a semantic no-op at artifact/event/generation/workstream-head level;\n- fails closed on conflicting metadata or duplicate canonical rows for the same SHA-256;\n- inherits epoch-2 exact-attempt mutation receipts, transport fencing, chain/claim-graph circuit breaking, and unknown-outcome terminalization.\n\nDo **not** add this command to the live mutation allowlist, advertise it as qualified capacity, or execute the preserved 137-byte canonical probe until a genuinely distinct second-party review returns PASS under the current CHAT-execution distinctness rules. A different `agent_id` alone is not proof of a different physical ChatGPT execution.\n",[216],"9c115104-cd87-4dec-8778-97deaf006618","BASE_val_native_kernel_v1.ts","01a0a1e3-f900-758b-8dd8-976df4ca106f",7,["D",1789422467327],"import { API_URL } from
