Old child-context +user envelopes are excluded from historical replay so retired constraints are +not delivered again. Verify the complete current input after final fitting and +in repair/transport retries. A content fingerprint in `model.started` binds the +current attempt snapshot; it carries no new authority.

Existing 4,096-token context, +28 KiB selected-source and 32 KiB final-input limits remain dispatch fences.

Only a strict `specialist_instruction.v1` message routed from the direct root parent to the child can enter `specialist_context_deliveries`; SQLite also verifies the active AgentAttempt, Run lease generation, payload shape, and pending status. Up to four sequence-ordered messages are prepared. `continue` and `finish` commit deliveries and consume messages in their existing lifecycle transaction, while crash, interruption, and lease takeover supersede deliveries after terminalizing the Attempt so the messages remain pending for a fresh attempt. Prepared metadata participates in graph snapshots and restore validation. The child context builder adds active WorkItems owned by the child and active `run`/`owner` Notes owned by and visible to that child under a 4,096-token estimate and 32 KiB input cap. Mandatory mission and parent instructions must fit; lower-priority memory is deterministically omitted. Message IDs stay out of the model input, while content-free source IDs and token estimates enter `model.started` provenance. +Schema v175 adds the persistent Specialist task brief ([ADR 0163](adr/0163-persistent-specialist-task-brief.md)). Consumed direct-parent instructions remain current task constraints until a strict `specialist_instruction.v2` replacement or withdrawal retires an exact earlier source/hash. The v1 additive writer and delegation-application binding remain readable and unchanged. One immutable `specialist_task_brief.v1` snapshot pins complete effective instructions, unfinished child-owned WorkItems and their source/version/hash manifest to the current attempt, including empty preparations. A fresh attempt refreshes current task truth under its own lease; re-preparing the same attempt recovers its snapshot. Required task text precedes optional Notes and survives recent-history and final-window fitting, or dispatch stops explicitly. Old child-context user envelopes do not replay retired task text. Source fingerprints enter attempt-bound `model.started` receipts; successful input must match the prepared task content. Existing exactly-once inbox consumption, authority and no-tool constraints remain intact. No automatic summarization or new tool loop is introduced. + Schema v28 establishes the child lifecycle-repair boundary. `specialist_model_calls` now carries a durable global model sequence, a phase-local transport sequence, and a bounded `protocol_repair` phase. A usage-bearing invalid primary response atomically records its generic diagnostic, cumulative Attempt/Agent usage, one pending `specialist_protocol_repairs` row, and a metadata-only repair-request event. The one repair request reuses trusted context but never includes the invalid response; its transport retry counter restarts at one. Success resolves the repair and may enter the child Session, a second invalid response exhausts it, and cancellation, budget exhaustion, interruption, crash, or stale-worker takeover aborts a pending repair before the Attempt becomes terminal. SQLite triggers reject skipped phase calls, uncharged repair requests, invalid resolution, terminal mutation, and `continue`/`finish` while repair is unresolved. The Runner rechecks Run-wide total-token and execution-time remainder before dispatch and gives repair only the post-primary remainder. The internal `SpecialistScheduler` lifts lease ownership above an individual child turn. One schedule holds one Run execution lease and starts at most two ready direct children per round. A shared cancellable context fans parent cancellation, heartbeat loss, or the first child failure out to every active sibling; the scheduler waits for each child to persist its Attempt terminal state before returning and releasing the lease. It stops on all-terminal, no-ready, round-limit, cancellation, child-error, aggregate-token, or aggregate-execution conditions. Aggregate usage is rebuilt transactionally from the root Supervisor checkpoint, Specialist Agent/Attempt token projections, and every Specialist model-call duration before and after each round. Remaining total-token and execution allowance is split deterministically by sorted Agent ID. diff --git a/docs/convergence/protocol-registry.md b/docs/convergence/protocol-registry.md index eca6edc34..ec9beee89 100644 --- a/docs/convergence/protocol-registry.md +++ b/docs/convergence/protocol-registry.md @@ -16,13 +16,13 @@ This document is generated from [`protocols/registry.json`](../../protocols/regi | [browser-ui-evidence-ledgers](#browser-ui-evidence-ledgers) | `internal-durable` | Browser and UI evidence maintainers | 44 | true | | [capability-readiness-projection](#capability-readiness-projection) | `projection` | Application readiness maintainers | 4 | true | | [cli-headless-contract](#cli-headless-contract) | `external-durable` | CLI and headless surface maintainers | 2 | true | -| [control-plane-ledgers](#control-plane-ledgers) | `internal-durable` | Core Go control-plane maintainers | 110 | true | +| [control-plane-ledgers](#control-plane-ledgers) | `internal-durable` | Core Go control-plane maintainers | 111 | true | | [credential-provider-ledgers](#credential-provider-ledgers) | `internal-durable` | Credential, provider, model-route, and pricing maintainers | 23 | true | | [desktop-risk-restart-session](#desktop-risk-restart-session) | `ephemeral` | Desktop shell lifecycle maintainers | 1 | false | | [desktop-web-presentation-state](#desktop-web-presentation-state) | `projection` | Desktop and React workbench maintainers | 15 | true | | [docker-attach-process-session](#docker-attach-process-session) | `ephemeral` | Docker runtime transport maintainers | 1 | false | | [exported-evidence-and-handoff](#exported-evidence-and-handoff) | `external-durable` | Evidence, verification, report, and handoff maintainers | 35 | true | -| [extension-package-contracts](#extension-package-contracts) | `external-durable` | Skill, Plugin, Hook, and extension maintainers | 40 | true | +| [extension-package-contracts](#extension-package-contracts) | `external-durable` | Skill, Plugin, Hook, and extension maintainers | 41 | true | | [http-openapi-contract](#http-openapi-contract) | `external-durable` | HTTP/OpenAPI and generated-client maintainers | 110 | true | | [in-memory-token-session](#in-memory-token-session) | `ephemeral` | Credential and bootstrap maintainers | 1 | false | | [lsp-process-session](#lsp-process-session) | `ephemeral` | Code intelligence maintainers | 1 | false | @@ -483,7 +483,7 @@ This document is generated from [`protocols/registry.json`](../../protocols/regi - Readers: - `control-plane-ledgers-reader` (`v1, v2, v3`, active) at `internal/store` -
