+## Backend convergence — 2026-11-02
+
+Project convergence #2171 now adds explicit repository associations and non-destructive Owner double-confirmed closure on the delivery branch. It preserves unfinished Task records and memory; runtime source migration and new behavior are not deployed. Role-governance and remaining convergence issues remain active.

 # FlyBot — Roadmap
 
+## Backend convergence — 2026-11-02
+
+Implement the 2026-11-02 convergence issues sequentially: Project boundaries, independent personal agents/authorization, execution and collaboration, context, Task/subtask lifecycle, SQLite/state, unified API/events, compatibility, then #2189 real deployment/README. Each issue has a separate main-repository branch/PR; no automatic merge or production rollout. #2171 starts with repository relations and Owner closure; role-governance acceptance remains tracked.

+
+## Project convergence — issue #2171
+
+Project records now retain description, goal and scope. ProjectRepository association
+records are keyed by a stable Project/repository digest; zero or many associations
+per Project and the same repository across Projects are supported. Loading migrates
+the legacy repository/defaultBranch once, preserving Task/Run ownership and the
+legacy execution target. Reads do not create associations. Linking another repository
+does not silently switch execution. Unlinking the selected legacy target is refused
+while unfinished work depends on it; explicit Task repository selection is a later
+Task-contract concern. With no unfinished work it can be removed, including the
+last association, without deleting a repository or rewriting existing history.
+
+Authenticated native endpoints: project-repositories (read), project-repository-link
+and project-repository-unlink (Owner/Maintainer configure), project-close-request
+(Owner/Maintainer suggestion), project-close-prepare and project-close-confirm
+(Owner personally). Preparation persists a hashed, owner-bound, expiring challenge
+and final record without closing. Confirmation rechecks current membership, principal,
+Project basis and challenge, then persists closed status and final record with current
+unfinished Task references. A matching owner retry returns the original closure.
+Delegated identities cannot confirm. A failed save restores the previous state.
+
+Closure is distinct from legacy archive/delete: it retains the Project, bindings,
+private/shared histories and memory, permits authorized reads and refuses further
+Project mutations/new work. It does not claim active external workers have exited;
+confirmed stop/reconciliation stays in the execution service. It adds no requirement
+to finish Tasks before closing. Legacy delete/archive cannot erase or relabel a closed
+Project. This stage preserves legacy interfaces; full role-change proposals/approval
+and dynamic execution compatibility remain tracked with role/execution convergence.

 Project convergence #2171 now adds explicit repository associations and non-destructive Owner double-confirmed closure on the delivery branch. It preserves unfinished Task records and memory; runtime source migration and new behavior are not deployed. Role-governance and remaining convergence issues remain active.

 ## Backend convergence — 2026-11-02
 
 Implement the 2026-11-02 convergence issues sequentially: Project boundaries, independent personal agents/authorization, execution and collaboration, context, Task/subtask lifecycle, SQLite/state, unified API/events, compatibility, then #2189 real deployment/README. Each issue has a separate main-repository branch/PR; no automatic merge or production rollout. #2171 starts with repository relations and Owner closure; role-governance acceptance remains tracked.

+# User-owned personal agents — #2170
+
+PersonalAgent is a user-owned identity independent of Project. Internal and external
+registrations do not require a Project. A participation joins that identity to an
+existing member's Project with a separate context scope and conversation carrier.
+Membership grants no extra agent privilege; a user's own agent can join without a
+second admission approval. A default participation selects exactly one private
+recipient, never broadcasts work. Permissions remain scoped by the represented
+human and current Project membership.
+
+## State and migration
+
+personalAgents holds stable identity, owner, kind/status and private memory scope.
+personalAgentParticipations holds agent/owner/Project, status, carrierId and
+contextScopeId. personalAgentDefaults selects a participation per user/Project.
+Tables are read at call time. Load migration relates legacy private Project agents
+to a stable user identity, preserving carrier, Bot, Session, notes, transcripts,
+proposals and grants at their existing keys. It does not merge private histories.
+Selecting another agent uses a separate carrier/context, not another user's notes.
+Native carriers record personalAgentId and participationId; scoped tools recheck
+active participation before and after asynchronous identity checks.
+
+## Native endpoints
+
+All use the existing authenticated POST /api/bot with endpoint/payload. The actual
+user is from authentication; body owner/member fields cannot select another user.
+
+| Endpoint | Payload | Result |
+| --- | --- | --- |
+| personal-agent-create | name, optional kind (internal/external); external provider and HTTPS endpoint | agent |
+| personal-agent-read | agentId | own agent, including retired identity |
+| personal-agent-list | optional limit 1–200, after | own agents, next cursor |
+| personal-agent-join | agentId, projectId | agent and participation |
+| personal-agent-default | agentId, projectId | selected active participation |
+| personal-agent-participations | optional limit 1–200, after | own participation page |
+| personal-agent-history | agentId, projectId, optional offset/limit 1–100 | own private transcript page, nextOffset |
+| personal-agent-leave | agentId, projectId | inactive participation, retained history |
+| personal-agent-retire | agentId | retired identity and participations, retained history |
+
+Writes reject read-only hosts and require the current user, not a Bot/delegated
+identity. Joining/default selection rechecks current Project rights. Leaving or
+retiring fences its carriers, revokes only their watch grants and requests existing
+watch cancellation; it never reports unknown workers exited. An ended default is
+not silently rejoined by reading a legacy agent endpoint. Private transcript reads
+remain available to their owner, without injecting them into shared context.
+
+External registration stores a descriptor with status unverified. It performs no
+network request, stores no credentials and does not imply grok-bot/dots login or
+provider execution succeeded. Selecting an external identity cannot silently
+instantiate a native model in its place. External authentication/transport is
+separately delivered under #2183/#2185. Compatibility with existing personal Chief
+carriers and broader migration remains #2186; runtime lifecycle remains #2184.
+
+Tests distinguish local contract/HTTP and migration validation from actual model
+and external-provider acceptance. The README/API publication stays deferred to
+#2189 after final backend interfaces stabilize.

+# Personal-agent connection authentication — #2183
+
+A connection represents a registered personal agent and its actual human owner.
+It is separate from browser authentication, Project membership, and the existing
+persistent safe/watch delegation. Internal and external identities use the same
+Project authority checks; provider names and body identity claims grant nothing.
+
+## Credentials and scope
+
+The user issues an opaque fba_ connection token for explicit active Project
+participations. Only its SHA-256 hash is persisted, with credential ID, owner,
+agent, Projects, issuer/subject binding, generation and expiry. The plaintext is
+returned once. TTL defaults to seven days, bounded to 60 seconds–30 days. Public
+credential lists omit hashes and paginate with limit/after. Unknown protocol or
+malformed generation/expiry/scope records refuse authentication. Authentication uses the existing member-session
+header on POST /api/bot, validates current agent/user/account binding and expiry,
+and checks the operator's existing platform principal checker where configured.
+It does not borrow a browser cookie. Platform deployments need the established
+background principal-check contract; missing evidence refuses authentication.
+
+The module installs after authz, wrapping authentication, Project permission,
+principal validation and endpoint policy. Effective permission intersects current
+human membership, credential Project scopes, active participation and current
+safe/watch grant. It does not infer access from the default-agent selection.
+Unknown host/private endpoints are denied. Project list/query results retain
+scope filtering; native private-agent history/full context cannot be borrowed by
+another agent connection. Summary public Chief metadata remains available.
+
+## Safe/watch and closure
+
+Safe connections may read scoped facts, create a private impactful Task proposal,
+and suggest Project closure. Proposals use stable agent/Project/request identity;
+a changed intent with the same key conflicts. They create no Task until the human
+explicitly approves via the existing proposal publication path. Approved Tasks
+retain the agent/connection/participation origin and approving user.
+
+Watch uses the existing projectAgentGrants per carrier; no second delegation
+engine is introduced. personal-agent-delegation-set selects the owned participation
+explicitly, so granting one agent does not grant another. Task publication records
+actual agent/credential/participation/grant provenance from authentication, not
+body metadata. Current human Project rank still gates configuration and delivery.
+Delegated connections cannot self-grant, publish a safe proposal as its human, or
+perform Owner's personal closure confirmation. Legacy delete/archive routes are
+not an alternative delegated closure path.
+
+The native private-agent project_agent_suggest_closure tool also permits a reasoned
+recommendation in safe mode without making a Task. The host derives its current
+carrier/participation; only Owner can personally double-confirm closure. Public
+Chief/read-only consultation sessions cannot impersonate a user's private agent.
+
+Revoking a connection/logout rejects that token without revoking other tokens,
+browser sessions or the separate watch mandate. Revoking watch removes future
+write authority and uses existing cancellation handling. Retiring/leaving fences
+participation and associated grants. Accepted Project Tasks are not silently
+cancelled because a transport disconnected. Unknown worker exit is never declared
+safe by a credential transition; execution lifecycle is #2184.
+
+## Native endpoints
+
+All use the existing authenticated endpoint/payload transport.
+
+| Endpoint | Caller / payload | Result |
+| --- | --- | --- |
+| personal-agent-token-create | Human owner: agentId, projectIds, optional ttlSeconds | token once, public credential metadata |
+| personal-agent-token-list | Human owner: agentId, optional limit/after | public credential page and next cursor |
+| personal-agent-token-revoke | Human owner: credentialId | revoked metadata |
+| personal-agent-delegation-set | Human owner: agentId, projectId, mode safe/watch | existing delegation view |
+| personal-agent-propose-task | Agent connection: projectId, title, criteria, projectTaskKind, requestId | private proposal, publishRequired |
+
+Writes refuse read-only hosts. Validation or failed issuance cannot return an
+active uncommitted connection. Hash comparison rejects malformed stored hashes.
+Task-origin records persist with the original Task snapshot; generalized operation
+receipts/events remain #2185 and transaction migration/recovery #2182.
+
+Tests cover in-process authenticated HTTP and a real loopback TCP HTTP client,
+privacy/scopes, proposal approval/replay, watch transitions, credential revocation,
+expiry/account changes, spoofing, malformed credentials and reload. This is not
+an official grok-bot/dots adapter or provider login verification. External endpoint
+descriptors remain unverified; no outbound provider network request is introduced.
+README/API publication stays deferred to #2189 after backend convergence.

+Task-role SDK retries retain pinned public persona/skills and the latest observed
+backend context across Attempts. Dynamic input is not a definition identity. A
+binding incompatibility or unknown old execution fails visibly; no silent fresh
+Session or rollback to older context. Definition snapshots are shared by digest,
+current rights still revoke execution, failed unused preparations release their
+pins, and model input follows a durable-save/cancellation barrier. Existing
+Harness/lease/Workflow services remain authoritative. Adapter capability inspection
+reports native Task-role continuation as pending; no new real-provider validation,
+public service protocol, SQL transaction, deployment or frontend change is claimed.

+## Execution convergence — #2184
+
+Task-role identity remains stable across Attempts. A content-addressed public
+`projectRoleDefinitionSnapshots` record pins persona, resolved skills and execution
+contract on first preparation; Session/Task records reference its id/hash/revision.
+Dynamic memory and current Task feedback remain per-turn inputs. A failed preparation
+without any prepared Session or observed worker drops only the unused pin; history
+and shared snapshots are retained. Existing prepared Sessions keep their version.
+Current role retirement, revoked shell permission, Harness change or removal of the
+previous resource from the approved pool prevents further execution. Definition
+changes appear in the returned Session context rather than replacing the persona.
+
+`spawn` prepares a worker and records the exact Task/Attempt/role/logical Session,
+resource/profile/Harness and lease generation. `dispatch` persists the running marker
+before writing model input and rechecks cancellation/lease generation after saving.
+A no-op save cannot authorize dispatch. The first observed backend Session is indexed,
+including failed/partial turns; a later retry cannot fall back to older completed
+context. If execution might have started but no backend id is known, recovery is
+explicitly blocked. Only a proven unstarted, released process may be skipped.
+Legacy prompt-based keys migrate only with matching environment and validated,
+scoped original role context; original worker/binding proofs are preserved.
+
+The existing service methods remain the lifecycle seam: delivery `preparePoolRole`,
+Harness `spawn`/`dispatch`, `input`/`taskInputWake`, `release`, and existing query views.
+`capabilities(harness)` reports implementation support independently of installation,
+login or successful inference: Codex/Claude support same-binding SDK continuation,
+between-turn input and abort/stop with acknowledged process exit. Native uses existing
+Bot turns/removal; native Task-role restoration is not yet advertised. Cross-Harness
+restoration is unsupported. An SDK capability declaration is not real-provider proof.
+
+This stage has subprocess/SDK-adapter regression coverage, not a new real-model run.
+Native Task-role continuation, unified public receipts/events (#2185), transactionally
+committed Effects (#2182), parent resumption (#2179), and final real-task validation
+remain explicit acceptance work. No second executor or scheduler is introduced.

 ## Scoped connection integration
 
 Private-agent persona v5 describes an independent identity/isolated participation and adds project_agent_suggest_closure. Safe private agents can recommend closure without a Task; host-derived participation is required, and Owner confirmation stays personal. Approved external private proposals retain persisted origin/approval provenance.
+
+
+## Consultation protocol — #2175
+
+Ordinary questions are `project-consultation/v1` views over the original private
+`conversation-handoff/v1` transcript records. `project-chief-question` remains a
+compatible ask alias, including its old `handoff` response field. It now also
+returns `consultation`; historical records remain readable without becoming Task
+handoffs. A consultation never transfers Task initiative or creates a Task.
+
+| Development operation | Native endpoint | Authority/result |
+| --- | --- | --- |
+| `consultation.ask` | `project-consultation-ask` | Current member/own scoped agent asks Chief |
+| `consultation.get` | `project-consultation-get` | Own selected participation, bounded reply page |
+| `consultation.list` | `project-consultation-list` | Own selected participation, receipt cursor |
+| `consultation.reply` | `project-consultation-reply` | Reply to an incoming Chief question only |
+
+Use `agentId` to select an owned participation; scoped connection credentials bind
+that selection to their own agent. A missing mailbox read does not allocate a Bot.
+External agents have transcript mailboxes, without pretending to log into a provider
+or silently starting a native personal agent. Outgoing answers are accepted only
+from the existing delegated Chief executor; callers cannot impersonate Chief through
+the reply endpoint. Full private notes/other-agent transcripts are never forwarded.
+
+Chief `needs-human` first addresses the initiating user's active default personal
+agent, or the Task requester when no initiation binding exists. The durable incoming
+question retains Task/decision/Chief-job ids in that participation's existing private
+transcript. No valid agent means explicit human fallback. `requiresHuman` adds a
+personal-only response boundary; Project closure still independently requires Owner
+confirmation. A changed default does not transfer the old question, grant or context.
+
+Safe replies remain private suggestions; an explicit current user publish is needed
+to send their text to the Project. Watch replies intersect current user/participation
+rights and the existing validated delegation. Published answers use the original
+Task inbox/Effects admission, retain approval/proxy provenance in the private receipt,
+and wake Chief through that inbox. Reply publication does not close/requeue a Task
+itself; Chief decides the next action. Exact requestId/text replay reuses the answer
+and Task-input record; altered text is refused. Stale decision replies are refused.
+
+The existing Effects dispatcher sends notifications only after the question snapshot
+commits. An already authorized native watch can be woken through `wakeWatch`; safe
+and external agents consume their own mailbox without an invented provider transport.
+`project_agent_consultations` is the native personal-agent tool for get/list/reply.
+An Effects attempt or SDK send is not a read/handling receipt. External responses
+still need a connected client; no official grok/dots integration is claimed.

+States distinguish pending, accepted, processed, revoked and invalidated. Processing
+one handoff never means Task completion. Initiative is held by the target pool before
+acceptance, then by its active claim; interrupted acceptance is fenced for recovery.
+Failure phase/reason is separate from acceptance. Source/target role contexts are
+server-resolved references, with immutable original references and actual receiving
+context/worker recorded at binding. Private transcripts and caller-supplied Session
+references are not copied. Summaries hold bounded completed/next requirements;
+trusted evidence is separate from model claims. Predecessor/successor ids retain
+normal handoff, return, transfer and Chief intervention chains.
+
+Trusted `roleCommand` adds `handoff.accept` (taskId,botId,handoffId,requestId) and
+`handoff.offer` (taskId,claim,requestId,payload.action/reason/to/outputs). These map to
+the same original claim/decision services. They are host execution ports; public HTTP
+cannot submit role tokens or invent a receiving identity. Accept response replay
+returns its original claim or historical outcome and cannot revive completed work.
+Old `claim`/`handoff`/`return`/`transfer`/`complete`/`arbitrate` ports remain compatible.
+
+Confirmed source exit precedes relinquishing an execution claim. Even after Chief
+observes a failed writer, a downstream non-Chief claim rechecks unresolved historical
+exits; selecting another resource cannot bypass them. Chief may still observe and
+arbitrate a blocked Task. Unknown occupancy remains visible and pending; a timeout
+is not release evidence. Native exit/restoration and transaction-wide recovery still
+follow the execution/storage acceptance work, not fabricated from these view states.

+Seen 1× (large-history regression). A bounded initial context does not bound a
+context tool returning every Task or note. Return a scoped index and hash/cursor
+pages, preserve required constraints, and preflight the exact native/SDK input.
+Aggregate SDK usage is not a measurement of current window occupancy. Structured
+native handoff input must remain JSON rather than `[object Object]`.

+notes retain history under bounded views. Codex tool history has an explicit cap;
+SDK compaction remains runtime-managed, without claiming aggregate usage is current
+window pressure. No new memory platform, executor or timer. Native Task-role physical

+### Context/memory convergence — 2026-11-03 (#2177)
+
+Unify model/Harness context budgeting and bounded source tools across persistent
+Chief and temporary roles. Unknown capacity stays explicit; full rules/current
+constraints remain required, retrieval yields before overflow, and native/SDK input
+is checked before delivery. Working summaries use original public role-memory
+records with exact source/evidence/uncertainty, separate resident Chief topics and
+rollback of uncommitted staging. Facts have source/classification/version/archive;
+role-authored experience cannot declare facts or overwrite human control. Private
+notes retain history under bounded views. Codex tool history has an explicit cap;
+SDK compaction remains runtime-managed, without claiming aggregate usage is current
+window pressure. No new memory platform, executor or timer. Native Task-role physical
+restore2184 and normalized SQL storage2182 remain separate acceptance; real SDK
+verification must name exact runtime source hashes, not borrow deterministic tests.

+# Scoped context, working summaries and memory
+
+Project context separates fixed role conventions, retrieved long-term memory, working
+summaries and original sources. It reuses role definitions, Task-role Sessions, public
+role-memory records, Chief topic memory, original parts/steward and immutable context
+archives. No second knowledge platform, executor or maintenance timer is installed.
+
+## Configured budgets
+
+The operator supplies `projectContext` beside the existing Project settings. Defaults
+are overridden by Harness, then exact model/profile identifier. Example numbers below
+are an operator's envelope, not a claim about a named model's actual capacity:
+
+```json
+{
+  "projectContext": {
+    "defaults": { "maxChars": 48000, "readChars": 6000, "toolOutputTokens": 2000 },
+    "harnesses": { "codex": { "toolOutputTokens": 2000 } },
+    "models": {
+      "operator-model-id": {
+        "windowTokens": 64000,
+        "outputTokens": 4096,
+        "toolTokens": 4096,
+        "protocolTokens": 2048,
+        "threshold": 0.8,
+        "memoryTokens": 4096,
+        "knowledgeTokens": 4096,
+        "summaryTokens": 4096
+      }
+    }
+  }
+}
+```
+
+`inputTokens = floor(windowTokens * threshold) - outputTokens - toolTokens -
+protocolTokens`. Optional fixed/current-input ceilings are `fixedTokens` and
+`currentInputTokens`. Native model metadata may supply the window/output default;
+a configured window cannot enlarge an observed provider window. SDK profile model
+selection is resolved again on the actual chosen resource before dispatch. Unknown
+capacity stays `capacitySource:unknown`, `windowTokens:null`, `withinBudget:null`;
+the existing character cap and bounded reads still apply, without guessing a
+universal model window. Invalid budgets fail before model input.
+
+`estimator:utf8-upper-bound` counts UTF-8 text bytes as a conservative token ceiling.
+`flybot-estimate` uses FlyBot's CJK/Latin estimate with a1.5 margin; it is an estimate,
+not an exact tokenizer. Neither mode claims precise SDK history or multimodal usage.
+Snapshot `budget/usage` and worker/native `inputUsage` expose configuration source,
+layer counts, selected/omitted public sources and reservations without private text.
+SDK aggregate turn usage is retained as usage, not mistaken for current window size.
+
+Role context accounts for complete policy and fixed persona/skills, current user
+constraints, working summary and retrieval. Optional retrieval yields first; required
+rules/constraints never silently disappear to make a load succeed. Current Project
+goal/scope and Task constraints remain explicit. SDK checks the actual final dispatch
+text. Native Workflow supplies its exact serialized input to the host's generation,
+authority, lease and durable-save check before sending it. Structured handoff/inbox
+objects remain JSON rather than becoming `[object Object]`. Cancellation while saving
+prevents delivery. The original native parts/steward still manages its full Session.
+
+## Long-term facts and working summaries
+
+Public role memory can have `factKey`, classification (`unclassified`, `fact`,
+`inference`, `unresolved`, `conflict`), active/archived status and expectedRevision.
+Repeated identical facts do not manufacture versions. Changes retain previous text,
+classification, status, author/source and time. Human facts require current configure
+authority; a memory note cannot change persona, collaboration rules or permissions.
+Archives remain readable through explicit history pages, while ordinary retrieval
+excludes archived records. Current default views omit nested version histories.
+
+Active role executions may record at most300 characters of experience under their
+current Project/Task/claim, using trusted `role.memory.record` or up to three optional
+`memory:[{text,factKey?,classification?}]` notes in their handoff response. Such notes
+are inference/unresolved/conflict, never self-certified facts. They cannot overwrite
+human-controlled facts or revive an archive. They retain Task/claim/generation/request
+provenance and are retrieved only for the same public role under its budget. A human
+may explicitly review/update them. Private user notes never enter this public store.
+
+A normal handoff stages a bounded Task-role working summary with its existing
+handoff/Effects commit. It includes requirement hashes, role claims, unresolved refs,
+next step and exact candidate/test/review references. A stale passing test stays stale;
+a candidate recommendation is not a signed repository PASS. The next return to that
+role loads its own summary, not another role's conversation. Previous versions remain
+in the original role-memory record. Failed uncommitted staging rolls back only the
+unchanged candidate and preserves concurrent updates/last valid summary.
+
+Resident Chief decisions update separate Task topics on its existing public carrier.
+Later turns retrieve relevant bounded topic summaries; all originals remain in scoped
+summary archives. A failed summary update records `contextIssue` without erasing an
+already applied Chief decision. Summary maintenance is deterministic at meaningful
+handoff/Chief boundaries; ordinary reads do not ask a Bot to rewrite project position.
+
+Private notes are retained independently of the default last100-item UI view. Existing
+`project-agents` supports `privateMemoryOffset/privateMemoryLimit` and
+`roleMemoryOffset/roleMemoryLimit`; limits are1–100. `roleMemoryId` with
+`versionOffset/versionLimit` reads a same-Project memory history page. This changes
+representation size, not ownership or publication rights.
+
+## Retrieval and tool results
+
+Relevant current facts/memory are ranked within per-layer budgets; exact duplicates
+with the same provenance/classification may be represented once. Different uncertainty
+or source metadata is not collapsed into a verified conclusion. Original rows remain
+in the immutable archive. `contextRequests` supports knowledge/memory/repository/summary
+sources and searchable index pages, with scope/hash/offset checks. Multiple reads
+share the reserved tool result envelope; an insufficient envelope fails explicitly.
+
+`project_agent_context` returns a bounded index instead of all Task/Run/private history.
+Its `sourceRequest:{kind,id?,offset?,sha256?,query?,revision?}` reads exact authorized
+project, task-index, task, private-memory, public-message, knowledge or role-memory
+sources. Source pages retain hashes/cursors and reject changed sources. Private sources
+always resolve through the current participation, and room sources through current
+room access. Chief `memoryRequests` supports own-topic offset/limit and charOffset
+pages; caller-supplied Bot/team scopes cannot retarget it. Check the result budget
+before durable memory writes so an oversized response cannot conceal a mutation.
+
+Codex receives a configured `tool_output_token_limit` for tool history; its own
+compaction and backend Session identity remain managed by the SDK runtime. See the
+[official configuration reference](https://learn.chatgpt.com/docs/config-file/config-reference).
+Claude continuation still uses its existing SDK adapter; generic Claude tool-output
+limits remain runtime-managed rather than claimed equivalent to Codex's setting.
+Harness capability inspection reports this distinction. Host scoped context tools
+remain bounded for both. SDK compaction never substitutes for FlyBot evidence,
+summary provenance, handoff receipts or current authorization.
+
+## Acceptance boundary
+
+Tests cover large history, required-rule failure, scoped pages, Task-role/Chief topic
+summaries, fact updates/archive/version retention, handoff commit failure, active-role
+experience, safe context reads, native input fences and SDK argument propagation.
+Controlled SDK processes and deterministic DSH tests are not a new real-provider
+long-task acceptance. Real-model verification is recorded separately by source hash.
+Native Task-role physical Session restoration remains #2184; new process identity is
+not called restored context merely because it shares a logical Task id. SQLite/delta
+storage and archive normalization remain #2182; bounded model injection does not mean
+the existing historical JSON store is already normalized or migrated.

 Repair R3 (#36): Project task pools now enforce the existing pure handoff validator via the trusted host adapter and reuse spawn/dispatch/release and result interception. New Project deliveries do not instantiate a static Workflow graph. `projectDispatch: workflow` retains explicit legacy graph execution and fixtures. See [pool contract](project-pools.md).

+Project native dispatch preserves structured handoff/Task-inbox inputs as JSON,
+including false/zero values. Before sending, it offers the exact final message to
+the host's optional execution.checkInput budget/generation fence. Refusal prevents
+send and uses the existing failure/release path; SDK dispatch retains its original
+host adapter. No graph, task-pool or UI replacement is introduced.

+used the existing operator-selected `gpt-6.1-sol` profile with a declared test budget.
+Two fresh workers changed fixture code and passed independent host Node tests; the
+returned worker resumed the same backend Session after a changed caller prompt,
+read its saved work summary, and recovered a conversation-only marker absent from
+repository files. Both workers confirmed stop and process exit before release.
+A large-output command completed with the configured CLI history cap. This proves
+SDK continuation under this controlled task, not a full Chief/pool run, an observed
+compaction event, an exact provider context-window measurement, or native restoration.

 2026-11-03 Seen 1×: a resident native Session may retain its system definition after bot metadata changes. Put each current job protocol/facts in the actual turn input; keep prior context historical and preserve the Session.

+### 2026-11-03 — A child result is neither parent completion nor integration
+
+Seen 1× while implementing #2179. Reusing old group aggregation would accept cancelled children and close the parent automatically. Project waits require Chief-adjudicated child outcomes and keep an explicit parent integration continuation. Releasing workers must also free the parent execution quota; an unknown lease still consumes it. Resuming the old claim must not manufacture a second source work-summary revision for the same completed execution.
+
+#2179 acceptance review: compare the complete requirements revision, not just title/criteria, before closing a candidate. A scope-only change still invalidates old evidence. A failed Attempt blocks the new Task commitment; it cannot silently become a terminal Task failure.

+#2179 policy-budget regression: active memory plus historical progress reports exceeded the existing complete-role-policy budget. Retain active invariants, archive dated candidate/run narratives with a source link, and preserve their full text. Do not raise the context ceiling, silently truncate required guidance, or reuse archived test counts as current evidence.

 resource-release reconciliation race, fixed with a red/green regression. Actual
 full R7 delivery and persistent 30-minute/restart acceptance remain in progress.
 
-### R7 (#40) collaboration candidate — 2026-11-01
-
-Scoped internal rooms now route @mentions to independent native/SDK role conversations,
-with member-bound histories/documents, public native text streaming and explicit stop.
-The shared UI adds safe Markdown, real pools/Timeline and readable role/evidence cards.
-[Capability inventory](docs/subsystems/project-collaboration.md) records restored paths,
-operator-only surfaces and limits. Tests use deterministic execution where stated.
-Loopback listening is refused in this worker sandbox, so Chromium/backend and real
-shared-service acceptance are pending; no completion, review PASS or deployment is claimed.
-
-R7 rework at prior candidate `f03f89d5b933fe315ad3fc937b3702533125bcb3` repairs
-the native stream listener registration expectation and browser fixture session-token
-adapter. Channel authentication checks run in verify without sockets or Chromium;
-actual browser and operator shared-service acceptance remain pending.
-
-
-Rework of the c9f9b5d candidate fixes the browser fixture through the real runtime save boundary and checks every rooms-page bootstrap endpoint for all three human roles before opening sockets. The current full-run log also exposed an invalid two-paragraph changelog fragment; the existing validator reproduces it and passes after consolidation. Chromium and deployed-service acceptance remain pending independent execution.
-R7 dogfood also exposed sandbox Git-index and host-test boundary failures. Scoped
-Codex writable roots support canonical generation; Chief route may resume a
-running pre-candidate Attempt without discarding uncommitted work. Explicit
-return or interrupted/candidate-backed work still creates a fresh Attempt. SDK
-release records carry actual stop-ack/process-exit proof, not terminal Task inference.
-
-The original DSH 1800-second schedule actually fired at 2026-10-31T21:54:39.260Z
-after browser logout and multiple backend restarts; exactly one actual Codex
-Chief Run completed. This proves the persistent 30-minute wake, not just a
-shortened-clock fixture. Remaining shared delivery/browser acceptance is separate.
-
-A real SDK sandbox/strace probe identified Unix pipe syscall denial as the remaining
-Node/Git subprocess blocker. Command roles use a named filesystem profile and the
-limited network proxy with no allowed destinations; Chief remains tool-free. Actual
-probe children succeed while outbound requests and outside-workspace writes fail.
-
-Chief recovery found a lifetime edge-budget refusal after several real environment
-repairs. Audited Chief intervention now begins a fresh bounded autonomous routing
-epoch while preserving full history and global quotas. Admission is checked before
-claim fencing or Attempt preparation; later preparation failure is explicitly blocked.
-
-Actual R7 candidate `56d14be` passed host full verification and complete deterministic
-Chromium/backend clicks. Independent Review was blocked by read-only temporary
-fixtures; command workers now bind a unique scratch directory and offline npm cache,
-without granting review-source writes. Cleanup follows confirmed SDK exit. Actual
-deployed three-account acceptance and independent approval remain separate.
-
-A tested pool checkpoint waiting for Chief/human input survives host restart only
-with a completed Chief Run and all registered SDK workers/leases confirmed released.
-It retains the candidate and test receipt; active claims or unknown exits still
-interrupt delivery. A checkpoint audit records the restart without inventing progress.
-
-Published delivery rework now carries the host's existing PR binding through Chief
-returns and human retries. Sealing keeps the old published candidate as an ancestor;
-publication rechecks the original PR/head and fast-forwards its branch, refusing
-concurrent/closed/mismatched artifacts rather than creating another PR. Actual
-PR48 remains unchanged until verified backend deployment and Chief-directed rework.
-
-Published rework now pins the actual GitHub target ref through the host broker.
-A resolved merge seals with both the old candidate and trusted upstream parents;
-roles receive that pinned input and publication rejects target movement or lost
-ancestry. Merged content still requires real host tests and independent Review.
-
-Role admission now replaces verified duplicate repository previews with complete-policy references, preserving full rules and all shared knowledge under the existing context cap. Preparation failures release unbound reservations and retain drafts; narrow host-proven rejected-admission checkpoints preserve the same Attempt across restart.
-
-Unstarted bound delivery now revalidates the live PR target before Developer allocation and audits a descendant-only target refresh on the same Attempt, preserving the original PR, candidate seed and unsealed draft. Active, unknown or previously recorded execution cannot silently retarget.
-
-Recurring M6 browser timeout reproduced at166: the native Chief correctly generated a safe-mode proposal, while the old fixture waited for an unapproved Task. Acceptance now verifies no early Task, cross-user rejection, explicit requester UI approval and idempotent publication before existing delivery checks; production authorization is unchanged.
-
-R7 P0 maintenance now resolves the pinned `e3ff1d26` upstream into the original
-`56d14be` candidate, retaining both collaboration and backend repairs. This is an
-unsealed integration draft until host tests and independent Review; Owner visual
-feedback remains outstanding and no overall completion is claimed.
-
-### R7 visual rework — 2026-11-01
-
-Issue #40/PR48 now separates the shared chat workspace from Settings, with persistent
-Project/room navigation, dedicated transcript/composer and expandable Task groups.
-The reference demo guides layout only; metrics, role configuration and execution
-summaries continue to come from scoped Project APIs. Failed/blocked Tasks remain
-visible under Needs attention. DOM regression is red on f5eb916 and green locally.
-Chromium screenshots and actual shared-service acceptance for this rework are pending;
-prior functional acceptance does not establish the owner's visual acceptance.
-
-Chief inspection may explicitly select one existing Task in its authorized Project. The host validates Project configuration authority and Task ownership before using the existing scoped snapshot mechanism. Other-Project/missing Tasks are rejected; unscoped inspection is unchanged. This reduces unrelated facts without dropping policy/knowledge or raising context limits.
-
-Owner basic-CI policy is implemented on the existing PR47 local branch: default pinned install/lint/build/canonical/core and plugin unit checks; heavy browser/runtime/package checks explicit extended dispatch. Independent Review and actual UI acceptance remain. Publish only at a safe upstream-binding checkpoint; this local change does not claim live workflow activation.
-
-- R6/#39 existing-PR publication recovery now has a manager-scoped endpoint that
-  revalidates original sealed role/test evidence and uses the guarded publisher.
-  It repairs read-after-push receipt gaps without a new Attempt, fabricated Review
-  or overall Task acceptance; see Project delivery architecture and regressions.
-- Chief resource context retains current/uncertain lease details and digests only
-  proven released history, preserving original records and the 48k admission limit.
-
-### R7 UI continuation — slow connections and public Bot inspection
-
-The same #40/PR48 continuation joins in-flight same-route loads, requests board/resource summaries without discarding audit history, and loads Settings/Workflow/member data only where displayed. Public Bot cards expose persona and attached same-Project/same-role public memory with revision/source. Settings retain existing permission checks. Native personal Chief/Bots/groups coexistence remains required and unfinished; Project rooms do not satisfy it. Browser throttling and current deployed three-account/visual acceptance remain separate from local unit evidence.
-
-
-The returned 653ebc2 candidate failed two repository workflow-shape assertions, not dependency preparation: they still required unconditional extended jobs and the retired shell gate. The #40 continuation aligns these assertions with the authorized basic/extended CI contract while retaining executable failure/cancellation coverage. UI/native-personal compatibility and new candidate host verification remain separate outstanding evidence.
-
-#40 continuation: Chief/private Project transcript now mounts original React
-Bubbles/Markdown and identity marks from scoped history, in lazy named assets.
-This is a partial native component slice, not personal-space/native-group compatibility
-or Owner visual acceptance. Exact checks and remaining adapter work travel with handoff.
-
-
-The current #40 continuation wires the original reply renderer to the Project/room observable source, including concurrent room streams and revocation clearing. It replaces the parallel room Markdown renderer. Personal Chief/Bots/native groups, complete Harness service adapters and current-source desktop/narrow/live acceptance remain unfinished; this is implementation progress, not Task acceptance.
-
-R7 continuation in the preserved #40 draft adds original personal Bot/group identity
-and history navigation, native sends and own-memory reads through a restricted
-adapter, plus original AssistantCell rendering. Focused HTTP/component checks are
-separate from pending full Harness shell/composer integration and actual deployed
-visual acceptance; #40 remains unfinished and no acceptance is claimed.
-
-Attempt8a continuation repaired native bundle/patch whitespace generation with
-red/green regression evidence and 36 focused passing checks. The draft remains
-unsealed; native shell/composer/tool/approval restoration and current-candidate
-verification/visual acceptance remain outstanding.
-
-- Fork basic CI checks out source in its tests-ok aggregation job and validates the current basic/extended policy in default workflow tests. The prior missing-script runner failure and stale inherited heavy-job assertions are repaired together, without bypassing failed verification.
-
-#40 recovered native UI draft continuation preserves original personal identities,
-history and native reply/list components; personal parent trees now use the original
-collapse renderer. This is unaccepted implementation, not full native shell parity.
-Native composer/services, complete personal controls and current browser/three-account
-visual acceptance remain outstanding and must not be inferred from unit checks.
-
-R7 pagination repair: personal Bot/archived-part history now has an earlier-page
-control instead of stopping at the latest 100 messages. Loaded pages survive
-polling and stay scoped to the opened identity/part; targeted regressions cover
-navigation and revocation. New candidate host verification and deployed acceptance
-remain separate.
-
-R6 context recovery: managers may publish an exact-source knowledge checkpoint
-through project-knowledge-write with hashed supersedes references. Original facts,
-versions and authors remain readable; role snapshots contain the current summary,
-newer facts and history digests under the unchanged48k cap. Invalid/stale checkpoints
-never hide original records. See Project agents architecture.
-
-Preparation-only retries retain an inherited sealed seed even when no new candidate
-was produced, so restarting after context repair cannot silently discard prior UI.
-
-#40 CSS/logout slice: original shell/conversation/sidebar rules now ship in the same-origin native stylesheet under the existing CSP. Sign out invalidates pending work immediately, including when an action is busy. Focused local tests are distinct from deployed visual acceptance; native composer/tool/approval and full legacy interaction parity remain outstanding.
-
-Failed-test rework now receives a bounded, redacted, hash-verified diagnostic from
-its own current or inherited candidate; unavailable private logs are not a model
-debugging prerequisite. Complete host logs remain retained and cannot mint PASS.
-
-#40 verification repair: the popup layering regression now follows the canonical extracted sidebar stylesheet, preserving its z-index assertions and checking the native sidebar re-export. Local red/green evidence is 11/12 → 12/12; this does not complete native composer or deployed three-account/weak-network acceptance.
-
-
-Task #40 rework: the inherited candidate failed the fragment validator because
-`40.fixed.md` contained multiple paragraphs. Keep one entry per fragment. The
-native conversation script now uses production React configuration and full
-minification, guarded by a 4.6 MB script budget (previous asset: 5.37 MB). This
-is a bounded reduction, not completed weak-network acceptance: embedded math
-fonts/CSS and the full native composer, tools, approval, stop/continue and
-personal/group interaction integration still require work. Operator deployment,
-three-account browser checks and actual screenshots remain pending.
-
-Task40 continuation moves native math fonts from CSP-blocked inline data URLs to
-individually loaded same-origin build assets. The stylesheet is 217104 bytes; local
-render regressions pass. Full host verification and actual shared-browser evidence
-remain pending; native composer/tool/approval integration remains unfinished.
-
+### Collaboration execution invariants and historical evidence
+
+Keep scoped Project/room role conversations and original native UI components;
+private user material stays private. The dispatcher uses actual native activity,
+not stored Bot existence. Chief inspection is a configured schedule; ordinary
+questions do not create Tasks. Source admission, rework, scratch/workspace cleanup
+and recovery require matching confirmed worker/lease exit. Unknown occupancy stays
+held. Audited Chief intervention may reset a bounded routing epoch, preserving
+history and global quotas. Preserve unsealed drafts and original Task/PR identity;
+reuse verified PR bindings and pinned target/source ancestry, never replace a PR
+or silently retarget recorded execution. Complete role rules and knowledge remain
+available under explicit budgets; release only truly unbound failed preparations.
+Safe-mode proposals require explicit requester approval; watch uses current grants.
+
+Dated candidates, environment probes, schedule observations and historical check
+counts are retained in [the implementation archive](docs/history/2026-11-02-collaboration-implementation.md).
+Their results are not evidence for the current source or Owner visual acceptance.
+
+### Current UI compatibility requirements
+
+Frontend Task40/PR48 remains its original continuation; backend work does not take
+it over or deploy it. Reuse original FlyBot conversation rendering, identity/parent
+trees, personal Chief/Bots, native groups and shared rooms. Preserve scoped public
+persona/memory inspection, earlier-part history paging, Markdown/math attachments,
+composer, tools, approvals and stop/continue. Project rooms do not substitute for
+native personal/group compatibility; partial restored components are not full parity.
+Keep failed/blocked work visible, load Settings only when needed, coalesce route
+loads and preserve current scoped polling/history. Native script budget is4.6MB;
+same-origin math assets must respect CSP. Actual desktop/narrow/weak-network,
+three-account screenshots and Owner visual acceptance remain separate evidence.
+
+Chief may inspect one explicitly authorized Task without admitting foreign IDs or
+dropping policy. Basic CI is the Owner-authorized default; extended browser/runtime
+checks remain explicit. Publication recovery reuses original sealed evidence and
+verified bindings; it is not overall Task acceptance. Resource views retain current
+and unknown leases while digesting only proven released history. Dated UI drafts,
+asset measurements and test reports remain in [the archive](docs/history/2026-11-02-collaboration-implementation.md).
 
 ### Task-scoped SDK context and resident Chief memory — 2026-11-01
-Owner requires a resident Chief with durable Project memory and one logical Session per Task/role. Codex/Claude own their supported conversation persistence and automatic compaction; FlyBot does not inject a second model-history compactor. SDK role rework reuses a confirmed released Task-role cwd/thread under the same principal/resource/profile/model/persona binding, while preserving separate immutable Attempt/claim/log/test/Review evidence. Changed bindings rotate backend threads with recorded lineage. Chief memory uses the original own-Bot MEMORY.md/topics/journal, never global team or private-user memory. Context admission keeps current bounded facts and hash-bound full source archives for scoped retrieval. Backend changes are foreground work; frontend Task40/PR48 resumes through FlyBot after validation.

SDK role rework reuses a confirmed released Task-role cwd/thread under the same principal/resource/profile/model/persona binding, while preserving separate immutable Attempt/claim/log/test/Review evidence. Changed or incompatible bindings expose an explicit context-resume problem and retain history; they cannot silently start a fresh conversation. Chief memory uses the original own-Bot MEMORY.md/topics/journal, never global team or private-user memory. Context admission keeps current bounded facts and hash-bound full source archives for scoped retrieval. Backend changes are foreground work; frontend Task40/PR48 resumes through FlyBot after validation.

-### Task40 S1 compatibility integration — 2026-11-02
-
-The preserved `0e72dc60` frontend is integrated with trusted operator backend
-`b920cae8` (including S1/34918fb3 and the shared verified-exit-proof repair).
-Legacy delivery/Chief/schedule/delegation requests enter the S1 facade; native
-personal/room/attachment routes and retained-root behavior remain intact. The
-compact board now supplies live native activity to the shared status mapper:
-stored Bot existence alone still cannot establish running execution. The new
-integration regression failed before that adaptation; focused integrated suites
-pass 83/83. Neither parent's prior validation is an integration PASS. Host full
-verification, independent Review and actual deployed three-account/weak-network/
-screenshot acceptance remain required. No deployment, push or PR replacement occurs.
+### Service and native compatibility invariants
 
+The shared service retains legacy delivery/Chief/schedule/delegation entrypoints,
+native personal/room/attachment paths and retained roots. Live status must use actual
+native activity. A completed Chief deferral is waiting-human, not an active execution
+claim. SDK-owned jobs accept only their fenced SDK callback, including the window
+before worker registration; dormant native events cannot consume them.
 
-Issue60 live follow-up: a completed arbitration deferral now leaves its own Chief
-claim waiting-human instead of active. Actual released SDK/lease proof remains
-required before source admission. This fixes the observed current-Attempt operator
-checkpoint without changing Task history, source trust or workspace ownership.
-
-
-S6 dependency preparation uses the complete deployed release graph, including native
-React/UI packages, rather than mixing the old private native cache. The versioned
-`dev/demo/prepare-worktree.mjs` adapter refuses unknown existing entries. For legacy
-managed workspaces, first prove SDK/leases released and preserve Git HEAD/index/status;
-back up their untracked dependency directory outside the worktree, then prepare as
-the service UID. Preserve the original Task/PR and source-admit the current Attempt
-through the Owner API. This operator migration does not edit task state or Git code.
-
-
-S6 live recovery also fences SDK-owned Chief delegations before asynchronous worker
-registration. Dormant native DSH turn/end events must not consume the scheduled SDK
-job during that setup window; only its fenced SDK callback may finish it. The
-regression injects that event before a worker ID exists, then requires exactly one
-completion from the actual bound callback. Native-only execution retains its events.
-
-
-A late result-handler failure cannot overwrite a confirmed released SDK lifecycle.
-Historical failed-status rows with a successful process exit may still prove exit
-only when worker ID/generation, Project/Attempt/role/resource and both worker/lease
-stop proofs match a released SDK lease exactly. Unknown/unreachable exits, missing
-proofs and mismatched leases remain refused. This preserves historical failure
-attribution without blocking every future integration admission for the same Task.
-
-
-Chief route with rework=false resumes an interrupted allocated pre-candidate
-Attempt after all role workers/leases/native occupancy are confirmed released,
-whether its worktree is clean or dirty. A clean operator-restart checkpoint must
-not manufacture a successor and discard its Attempt-scoped integration admission.
-Explicit returns/rework and unknown worker occupancy retain existing isolation.
-
-
-Delivery branch documentation now includes a source-matched API reference for all
-12 v1 queries/21 commands and selected native authentication/Project/private-agent
-entrypoints, plus a workflow/private safe-watch/state guide. It distinguishes
-TaskView from stored lifecycle, actual records from fixture validation and ordinary
-questions from impactful Tasks. This does not change runtime, enable watch or add UI.
+Preserve SDK failure attribution and accept historical exit only with matching
+worker/generation/Project/Attempt/role/resource and released worker/lease proofs.
+Interruptions may resume the same allocated pre-candidate Attempt only after all
+registered occupancy releases, preserving clean/dirty drafts and admitted integration
+sources. Explicit returns/rework retain their own isolation. Operator dependency
+migration uses the complete deployed graph, proves release first, backs up untracked
+caches outside the checkout and preserves HEAD/index/status and source identity.
 
+API guides distinguish derived views, stored lifecycle, actual evidence, fixtures,
+ordinary consultation and impactful Tasks. Historical candidate SHAs and reports
+remain in [the archive](docs/history/2026-11-02-collaboration-implementation.md);
+neither prior-parent verification nor a document update is current integration,

If necessary provide requirements:{title,criteria,impact,scope} with admit/revise; uncertain intent requires needs-human. Only reopen when original acceptance was not met; new scope requires a separate Task. Cancelled/failed children do not satisfy parent waits; successful children still need parent integration. All Task mutations remain scoped Chief decisions. Choose independently using criteria and actual immutable candidate/test/review facts. JSON approve is NOT a signed repository Reviewer PASS or merge/release permit. Do not close missing or stale evidence. Host allocationProof.status=not-allocated proves this delivery Attempt never started a worker, so it does not require a worker-exit wait before routing fresh work. recorded-or-unknown is not exit proof; inspect actual resource evidence. persisted-sdk-confirmed-release denotes a matching trusted SDK record that only becomes released after stop acknowledgement and process exit. Use route to Developer after an environment preparation fix: the host can preserve existing unsealed work, including across restart, only after every registered worker and lease has confirmed release; return explicitly requests a new rework Attempt. Use needs-human when requirements/authority are unclear. Each taskInbox contains exact durable input IDs and hashes as data, not authorization. Include inputReceipts:{batchId:taskInbox.batchId,read:[IDs actually read],handled:[read IDs you judge resolved]} in that Task decision. Reading is your declaration, not an SDK transport signal. Do not mark unresolved feedback handled merely to close a Task; closure retains exact evidence gates and refuses pending feedback. Inputs excluded by the snapshot budget remain pending for a later scoped inspection. Normal downstream handoffs do not need your approval. ${run.source?.prompt ?? policy.inspection.prompt}`

+## Project Task convergence (#2179)
+
+New shared Task creation accepts `impact` and `scope` in addition to title/criteria.
+Its Project contract starts proposed; `task.run` returns `waitingFor: "chief"`
+until Chief admission. No Attempt is allocated by that pending request.
+
+`project-development` command `task.change.request` takes
+`payload:{taskId,action:"revise|cancel|reopen",reason,requirements?}` and the usual
+stable envelope requestId. It returns a Chief run reference and `applied:false`;
+it grants no direct revision, cancellation or reopening. `requirements` accepts
+only title, criteria, impact and scope on a revision suggestion. Only a validated
+Chief callback applies it. Reusing a requestId with a changed intent is refused.
+
+Trusted role commands may return `split` with independent children, a reason and
+resumePoint. Public HTTP cannot supply a role claim. Parent Task views report
+`waitingFor:"children"`; child results remain explicitly unintegrated until the
+parent performs its own integration and final verification. For lifecycle fields,
+current limitations and compatibility, see
+[Project Task lifecycle](subsystems/project-task-lifecycle.md).

+### R7 (#40) collaboration candidate — 2026-11-01
+
+Scoped internal rooms now route @mentions to independent native/SDK role conversations,
+with member-bound histories/documents, public native text streaming and explicit stop.
+The shared UI adds safe Markdown, real pools/Timeline and readable role/evidence cards.
+[Capability inventory](docs/subsystems/project-collaboration.md) records restored paths,
+operator-only surfaces and limits. Tests use deterministic execution where stated.
+Loopback listening is refused in this worker sandbox, so Chromium/backend and real
+shared-service acceptance are pending; no completion, review PASS or deployment is claimed.
+
+R7 rework at prior candidate `f03f89d5b933fe315ad3fc937b3702533125bcb3` repairs
+the native stream listener registration expectation and browser fixture session-token
+adapter. Channel authentication checks run in verify without sockets or Chromium;
+actual browser and operator shared-service acceptance remain pending.
+
+
+Rework of the c9f9b5d candidate fixes the browser fixture through the real runtime save boundary and checks every rooms-page bootstrap endpoint for all three human roles before opening sockets. The current full-run log also exposed an invalid two-paragraph changelog fragment; the existing validator reproduces it and passes after consolidation. Chromium and deployed-service acceptance remain pending independent execution.
+R7 dogfood also exposed sandbox Git-index and host-test boundary failures. Scoped
+Codex writable roots support canonical generation; Chief route may resume a
+running pre-candidate Attempt without discarding uncommitted work. Explicit
+return or interrupted/candidate-backed work still creates a fresh Attempt. SDK
+release records carry actual stop-ack/process-exit proof, not terminal Task inference.
+
+The original DSH 1800-second schedule actually fired at 2026-10-31T21:54:39.260Z
+after browser logout and multiple backend restarts; exactly one actual Codex
+Chief Run completed. This proves the persistent 30-minute wake, not just a
+shortened-clock fixture. Remaining shared delivery/browser acceptance is separate.
+
+A real SDK sandbox/strace probe identified Unix pipe syscall denial as the remaining
+Node/Git subprocess blocker. Command roles use a named filesystem profile and the
+limited network proxy with no allowed destinations; Chief remains tool-free. Actual
+probe children succeed while outbound requests and outside-workspace writes fail.
+
+Chief recovery found a lifetime edge-budget refusal after several real environment
+repairs. Audited Chief intervention now begins a fresh bounded autonomous routing
+epoch while preserving full history and global quotas. Admission is checked before
+claim fencing or Attempt preparation; later preparation failure is explicitly blocked.
+
+Actual R7 candidate `56d14be` passed host full verification and complete deterministic
+Chromium/backend clicks. Independent Review was blocked by read-only temporary
+fixtures; command workers now bind a unique scratch directory and offline npm cache,
+without granting review-source writes. Cleanup follows confirmed SDK exit. Actual
+deployed three-account acceptance and independent approval remain separate.
+
+A tested pool checkpoint waiting for Chief/human input survives host restart only
+with a completed Chief Run and all registered SDK workers/leases confirmed released.
+It retains the candidate and test receipt; active claims or unknown exits still
+interrupt delivery. A checkpoint audit records the restart without inventing progress.
+
+Published delivery rework now carries the host's existing PR binding through Chief
+returns and human retries. Sealing keeps the old published candidate as an ancestor;
+publication rechecks the original PR/head and fast-forwards its branch, refusing
+concurrent/closed/mismatched artifacts rather than creating another PR. Actual
+PR48 remains unchanged until verified backend deployment and Chief-directed rework.
+
+Published rework now pins the actual GitHub target ref through the host broker.
+A resolved merge seals with both the old candidate and trusted upstream parents;
+roles receive that pinned input and publication rejects target movement or lost
+ancestry. Merged content still requires real host tests and independent Review.
+
+Role admission now replaces verified duplicate repository previews with complete-policy references, preserving full rules and all shared knowledge under the existing context cap. Preparation failures release unbound reservations and retain drafts; narrow host-proven rejected-admission checkpoints preserve the same Attempt across restart.
+
+Unstarted bound delivery now revalidates the live PR target before Developer allocation and audits a descendant-only target refresh on the same Attempt, preserving the original PR, candidate seed and unsealed draft. Active, unknown or previously recorded execution cannot silently retarget.
+
+Recurring M6 browser timeout reproduced at166: the native Chief correctly generated a safe-mode proposal, while the old fixture waited for an unapproved Task. Acceptance now verifies no early Task, cross-user rejection, explicit requester UI approval and idempotent publication before existing delivery checks; production authorization is unchanged.
+
+R7 P0 maintenance now resolves the pinned `e3ff1d26` upstream into the original
+`56d14be` candidate, retaining both collaboration and backend repairs. This is an
+unsealed integration draft until host tests and independent Review; Owner visual
+feedback remains outstanding and no overall completion is claimed.
+
+
+### R7 visual rework — 2026-11-01
+
+Issue #40/PR48 now separates the shared chat workspace from Settings, with persistent
+Project/room navigation, dedicated transcript/composer and expandable Task groups.
+The reference demo guides layout only; metrics, role configuration and execution
+summaries continue to come from scoped Project APIs. Failed/blocked Tasks remain
+visible under Needs attention. DOM regression is red on f5eb916 and green locally.
+Chromium screenshots and actual shared-service acceptance for this rework are pending;
+prior functional acceptance does not establish the owner's visual acceptance.
+
+Chief inspection may explicitly select one existing Task in its authorized Project. The host validates Project configuration authority and Task ownership before using the existing scoped snapshot mechanism. Other-Project/missing Tasks are rejected; unscoped inspection is unchanged. This reduces unrelated facts without dropping policy/knowledge or raising context limits.
+
+Owner basic-CI policy is implemented on the existing PR47 local branch: default pinned install/lint/build/canonical/core and plugin unit checks; heavy browser/runtime/package checks explicit extended dispatch. Independent Review and actual UI acceptance remain. Publish only at a safe upstream-binding checkpoint; this local change does not claim live workflow activation.
+
+- R6/#39 existing-PR publication recovery now has a manager-scoped endpoint that
+  revalidates original sealed role/test evidence and uses the guarded publisher.
+  It repairs read-after-push receipt gaps without a new Attempt, fabricated Review
+  or overall Task acceptance; see Project delivery architecture and regressions.
+- Chief resource context retains current/uncertain lease details and digests only
+  proven released history, preserving original records and the 48k admission limit.
+
+### R7 UI continuation — slow connections and public Bot inspection
+
+The same #40/PR48 continuation joins in-flight same-route loads, requests board/resource summaries without discarding audit history, and loads Settings/Workflow/member data only where displayed. Public Bot cards expose persona and attached same-Project/same-role public memory with revision/source. Settings retain existing permission checks. Native personal Chief/Bots/groups coexistence remains required and unfinished; Project rooms do not satisfy it. Browser throttling and current deployed three-account/visual acceptance remain separate from local unit evidence.
+
+
+The returned 653ebc2 candidate failed two repository workflow-shape assertions, not dependency preparation: they still required unconditional extended jobs and the retired shell gate. The #40 continuation aligns these assertions with the authorized basic/extended CI contract while retaining executable failure/cancellation coverage. UI/native-personal compatibility and new candidate host verification remain separate outstanding evidence.
+
+#40 continuation: Chief/private Project transcript now mounts original React
+Bubbles/Markdown and identity marks from scoped history, in lazy named assets.
+This is a partial native component slice, not personal-space/native-group compatibility
+or Owner visual acceptance. Exact checks and remaining adapter work travel with handoff.
+
+
+The current #40 continuation wires the original reply renderer to the Project/room observable source, including concurrent room streams and revocation clearing. It replaces the parallel room Markdown renderer. Personal Chief/Bots/native groups, complete Harness service adapters and current-source desktop/narrow/live acceptance remain unfinished; this is implementation progress, not Task acceptance.
+
+R7 continuation in the preserved #40 draft adds original personal Bot/group identity
+and history navigation, native sends and own-memory reads through a restricted
+adapter, plus original AssistantCell rendering. Focused HTTP/component checks are
+separate from pending full Harness shell/composer integration and actual deployed
+visual acceptance; #40 remains unfinished and no acceptance is claimed.
+
+Attempt8a continuation repaired native bundle/patch whitespace generation with
+red/green regression evidence and 36 focused passing checks. The draft remains
+unsealed; native shell/composer/tool/approval restoration and current-candidate
+verification/visual acceptance remain outstanding.
+
+- Fork basic CI checks out source in its tests-ok aggregation job and validates the current basic/extended policy in default workflow tests. The prior missing-script runner failure and stale inherited heavy-job assertions are repaired together, without bypassing failed verification.
+
+#40 recovered native UI draft continuation preserves original personal identities,
+history and native reply/list components; personal parent trees now use the original
+collapse renderer. This is unaccepted implementation, not full native shell parity.
+Native composer/services, complete personal controls and current browser/three-account
+visual acceptance remain outstanding and must not be inferred from unit checks.
+
+R7 pagination repair: personal Bot/archived-part history now has an earlier-page
+control instead of stopping at the latest 100 messages. Loaded pages survive
+polling and stay scoped to the opened identity/part; targeted regressions cover
+navigation and revocation. New candidate host verification and deployed acceptance
+remain separate.
+
+R6 context recovery: managers may publish an exact-source knowledge checkpoint
+through project-knowledge-write with hashed supersedes references. Original facts,
+versions and authors remain readable; role snapshots contain the current summary,
+newer facts and history digests under the unchanged48k cap. Invalid/stale checkpoints
+never hide original records. See Project agents architecture.
+
+Preparation-only retries retain an inherited sealed seed even when no new candidate
+was produced, so restarting after context repair cannot silently discard prior UI.
+
+#40 CSS/logout slice: original shell/conversation/sidebar rules now ship in the same-origin native stylesheet under the existing CSP. Sign out invalidates pending work immediately, including when an action is busy. Focused local tests are distinct from deployed visual acceptance; native composer/tool/approval and full legacy interaction parity remain outstanding.
+
+Failed-test rework now receives a bounded, redacted, hash-verified diagnostic from
+its own current or inherited candidate; unavailable private logs are not a model
+debugging prerequisite. Complete host logs remain retained and cannot mint PASS.
+
+#40 verification repair: the popup layering regression now follows the canonical extracted sidebar stylesheet, preserving its z-index assertions and checking the native sidebar re-export. Local red/green evidence is 11/12 → 12/12; this does not complete native composer or deployed three-account/weak-network acceptance.
+
+
+Task #40 rework: the inherited candidate failed the fragment validator because
+`40.fixed.md` contained multiple paragraphs. Keep one entry per fragment. The
+native conversation script now uses production React configuration and full
+minification, guarded by a 4.6 MB script budget (previous asset: 5.37 MB). This
+is a bounded reduction, not completed weak-network acceptance: embedded math
+fonts/CSS and the full native composer, tools, approval, stop/continue and
+personal/group interaction integration still require work. Operator deployment,
+three-account browser checks and actual screenshots remain pending.
+
+Task40 continuation moves native math fonts from CSP-blocked inline data URLs to
+individually loaded same-origin build assets. The stylesheet is 217104 bytes; local
+render regressions pass. Full host verification and actual shared-browser evidence
+remain pending; native composer/tool/approval integration remains unfinished.
+
+
+
+### Task40 S1 compatibility integration — 2026-11-02
+
+The preserved `0e72dc60` frontend is integrated with trusted operator backend
+`b920cae8` (including S1/34918fb3 and the shared verified-exit-proof repair).
+Legacy delivery/Chief/schedule/delegation requests enter the S1 facade; native
+personal/room/attachment routes and retained-root behavior remain intact. The
+compact board now supplies live native activity to the shared status mapper:
+stored Bot existence alone still cannot establish running execution. The new
+integration regression failed before that adaptation; focused integrated suites
+pass 83/83. Neither parent's prior validation is an integration PASS. Host full
+verification, independent Review and actual deployed three-account/weak-network/
+screenshot acceptance remain required. No deployment, push or PR replacement occurs.
+
+
+Issue60 live follow-up: a completed arbitration deferral now leaves its own Chief
+claim waiting-human instead of active. Actual released SDK/lease proof remains
+required before source admission. This fixes the observed current-Attempt operator
+checkpoint without changing Task history, source trust or workspace ownership.
+
+
+S6 dependency preparation uses the complete deployed release graph, including native
+React/UI packages, rather than mixing the old private native cache. The versioned
+`dev/demo/prepare-worktree.mjs` adapter refuses unknown existing entries. For legacy
+managed workspaces, first prove SDK/leases released and preserve Git HEAD/index/status;
+back up their untracked dependency directory outside the worktree, then prepare as
+the service UID. Preserve the original Task/PR and source-admit the current Attempt
+through the Owner API. This operator migration does not edit task state or Git code.
+
+
+S6 live recovery also fences SDK-owned Chief delegations before asynchronous worker
+registration. Dormant native DSH turn/end events must not consume the scheduled SDK
+job during that setup window; only its fenced SDK callback may finish it. The
+regression injects that event before a worker ID exists, then requires exactly one
+completion from the actual bound callback. Native-only execution retains its events.
+
+
+A late result-handler failure cannot overwrite a confirmed released SDK lifecycle.
+Historical failed-status rows with a successful process exit may still prove exit
+only when worker ID/generation, Project/Attempt/role/resource and both worker/lease
+stop proofs match a released SDK lease exactly. Unknown/unreachable exits, missing
+proofs and mismatched leases remain refused. This preserves historical failure
+attribution without blocking every future integration admission for the same Task.
+
+
+Chief route with rework=false resumes an interrupted allocated pre-candidate
+Attempt after all role workers/leases/native occupancy are confirmed released,
+whether its worktree is clean or dirty. A clean operator-restart checkpoint must
+not manufacture a successor and discard its Attempt-scoped integration admission.
+Explicit returns/rework and unknown worker occupancy retain existing isolation.
+
+
+Delivery branch documentation now includes a source-matched API reference for all
+12 v1 queries/21 commands and selected native authentication/Project/private-agent
+entrypoints, plus a workflow/private safe-watch/state guide. It distinguishes
+TaskView from stored lifecycle, actual records from fixture validation and ordinary
+questions from impactful Tasks. This does not change runtime, enable watch or add UI.

+
+# Project Task lifecycle
+
+The original Task remains the business identity. Its additive `projectTask/v1`
+contract separates admission, versioned requirements, dependencies, the parent
+continuation and final-result history from legacy board status. Consultation never
+creates one. Original Attempt, Handoff, Session, lease and Effects records keep their
+existing identities and persistence; this module adds no scheduler or datastore.
+
+## Admission and requirements
+
+New shared Project Tasks are proposed first. Title, acceptance criteria and project
+impact must be explicit before Chief admits them; scope may be supplied as well.
+Creation commits `task.intake` alongside the Task. Its existing Effects adapter asks
+the resident Chief for an intake turn; missing configured authority defers visibly.
+A run request before acceptance returns `waitingFor: chief`, allocating no Attempt.
+The actual Chief callback validates the current actor, Project, snapshot generation
+and requirements revision before applying `admit` and committing `task.start`.
+The start effect rechecks the original requester's live membership and permissions.
+No model-provided member identity or public role token grants Chief authority.
+
+Chief `revise` retains the original requirements and increments their revision;
+it also stages an ordinary durable Task input with Chief-decision provenance. The
+current execution receives that increment through the existing inbox notification
+path. Old requirement-bound delivery evidence cannot close the changed Task. Notes
+and supplemental inputs are distinct from lowering acceptance requirements.
+
+`task.change.request` accepts a member's cancellation/reopen/revision request and
+asks Chief to judge it. It does not apply the change itself. Chief cancellation
+refuses an active execution claim; any unconfirmed historical lease remains held
+and must reconcile before new execution. It never treats unknown exit as release. Reopening records the previous result and adjudication, retains the
+original requirements and logical role Sessions, and schedules another Attempt.
+New goals require another Task. An unresolved active cancellation needs the existing
+stop/reconciliation path before adjudication; no invented forced-exit proof.
+
+## Parallel children and continuation
+
+The current role may return a `split` decision with one to sixteen independent
+`children:[{title,criteria,impact,scope?}]`, a reason and a bounded `resumePoint`.
+Children use the same trusted Task constructor as public creation. After source
+stop/exit confirmation, one Effects commit persists child proposals, the parent wait,
+its own role summary, and child-intake intents. Failed/unconfirmed commits cannot
+execute the children. Existing parent workspaces and Task-role context are retained;
+children obtain distinct Task workspaces and need their own Chief admission.
+
+The parent holds no active execution claim while waiting. Its released Attempt does
+not consume execution quota, while any remaining lease or native worker still does.
+Each dependency requires an accepted child with explicit Chief completion provenance;
+cancelled/failed children remain unsatisfied. Parent/child scope and graph validation
+reject foreign Projects, duplicate children and cycles. Child results carry original
+Task/Attempt, criteria revision, candidate and decision references; `integrated:false`
+means the result has not yet been integrated into the parent's candidate.
+
+The existing outbox stages a stable `task.resume` only after all waits are satisfied.
+Pool serialization and the stable `children-<wait>` Handoff request prevent duplicate
+parent admission, including repeated callbacks and restart replay. The receiving
+role uses the same parent Task/Attempt/workspace and logical Session, reads its own
+summary and child result references, and continues integration. All children ending
+never closes the parent. Current dependency state is checked again before execution
+and Chief completion. Required code integration still uses the existing pinned-source
+admission/evidence gates; child completion is not a merge or publication permit.
+
+## Compatibility and evidence
+
+Persisted Tasks without this contract retain their old delivery/board semantics.
+Legacy personal/group Tasks and fixed Workflow execution remain available; their
+older group aggregation is not reused for Project child waits. New Project Tasks
+cannot use generic board transitions, legacy task-drive dispatch, or human delivery
+acceptance to bypass Chief. Legacy adoption is an explicit scoped Chief admission,
+refused during active legacy delivery.
+
+Tests distinguish pre-contract delivery fixtures from new admission fixtures. They
+cover the real Chief callback and committed-start seam using deterministic execution,
+concurrent resume, original role/Attempt continuity, failed exit, failed commit,
+requirements snapshots, scope/cycles and cancelled children. This is not a claimed
+new real-provider full Chief/child-integration acceptance. Native physical Session
+restoration remains #2184, storage normalization #2182, and complete public command
+receipts/events #2185. Those dependencies must finish before closing #2179.
+
+## Admission and compatibility checks
+
+Execution start retains the authenticated initiating principal/session, never the body session field, so a platform background check cannot borrow another session. Removing a source Bot records a carrier notice without cancelling the independent Task commitment. Cancellation also uses a durable transition marker so a post-commit save error cannot roll back an already committed decision in memory.
+
+Attempts pin the complete Project requirements revision, including impact/scope. A scope-only change invalidates old completion evidence even if title and criteria are unchanged. Rework after a revision creates a successor with the new requirements snapshot, retaining the prior version and logical Task-role Session.
+
+A failed Attempt leaves a new Project Task blocked with its source Attempt/reason; it does not close the commitment or erase Chief admission. A later active Attempt clears that execution block. Pre-contract legacy Task failure semantics remain unchanged.

 The restricted gateway exposes scoped personal-agent credential/delegation/proposal endpoints over the existing HTTP transport. Credential provisioning remains human-only; external requests cannot fall through to generic host or private-agent APIs.
+
+## Project Task lifecycle convergence (#2179)
+
+Project execution quota excludes a parent waiting for independently admitted children only when all parent leases and ephemeral workers have released. Any unknown occupancy continues to count. New Task run requests return waitingFor:chief before repository preflight or allocation if Chief has not admitted their requirements.
+
+The legacy Workflow gateway now also excludes Chief control jobs from execution quota. A real DSH admission probe reproduced a first delivery failing while its Chief intake was still finishing; the shared quota regression protects both the gateway and scheduler.

+## Accepted child sources (#2179)
+
+A code parent resuming an adjudicated parallel wait obtains sources through the
+host's private pre-input port, before resource reservation or worker registration.
+It requires the exact current active, unstarted claim, live initiating authority,
+confirmed exit of every related parent Attempt, and current Chief-accepted child
+outcomes. Code evidence must name the same candidate in implementation, passing
+host-test and approving Review records. Cross-repository results stay references;
+only same-repository code is admitted for integration. Qualitative Chief waivers
+remain judgements and cannot manufacture a candidate or passing test evidence.
+
+`integration.child-refs` commits through the existing Effects outbox before creating
+immutable, compare-and-set operator references to already registered Git objects.
+`integration.admit` records the wait ID, source fingerprint and original result
+references. The private port does not grant configure permission to public callers,
+does not advance its own reserved claim generation and preserves the working tree
+and index. Public operator admission retains its existing configure and writer-exit
+gates. A failed durable intent cannot create source refs; a moved ref is never
+silently overwritten. Inputs are bounded to twenty, accommodating sixteen child
+sources plus existing operator inputs. No network fetch or ambient credential is
+introduced by child admission.
+
+A source reference is not merged code. Before sealing or acceptance, the parent
+must retain current dependency outcomes and their committed source admission. The
+actual staged tree must include every required input's ancestry. The host reads
+**all** bounded MERGE_HEAD records, including octopus merges, from the registered
+Git metadata; unknown additional parents, duplicate/malformed data, symlinks and
+foreign worktree metadata are refused. Resource-clone inspection uses its live
+resource binding. Git regression tests exercise actual multi-parent merges and
+exact tree/parent sealing; their child acceptance records and publisher are explicit
+deterministic fixtures, not a real-provider full collaboration claim.

+## Exceptional dependency judgement
+
+Chief snapshots carry each linked dependency's exact current version. Protected
+`resolve-dependency` decisions require that version, a reason and bounded evidence
+references. Chief may waive a condition explicitly, or substitute a same-Project,
+Chief-accepted result with its own exact outcome version. The decision records
+`chief-judgement-not-host-tests` and never accepts the failed/cancelled original
+child or closes the parent. A changed/reopened replacement invalidates the waiver
+and blocks integration again. Formal cancellation or reopening of a linked child
+stages one dependency-review request to the resident Chief; ordinary operations do
+not call a model to reconsider Project positioning.
+
+Wait IDs cannot be reused. A later split preserves the previous wait and dependency
+records in history. Resume remains idempotent across retries. A sealed pre-split
+candidate continues in one successor Attempt without editing the original evidence;
+Task-role context remains stable. The accepted-child source admission protocol is
+specified in project-delivery.md. A plan changed after a parent has resumed requires
+execution stopping/reconciliation; current guards refuse stale integration rather
+than pretending the changed wait has completed.

Publish a newer-version JSON guard before initialization, validate one authority, and retain a fenced resumable rollback marker across partial moves. A transaction commit must precede Effects acknowledgement without a fallible post-commit read masking that proof.

+# Transactional runtime state
+
+The original Store and domain services remain the only runtime objects. Set the
+FlyBot plugin configuration `stateStorage: sqlite` to opt into SQLite. Existing
+JSON deployments remain JSON until selected. SQLite requires Node.js22.18 or newer;
+this implementation is tested on Node.js22.22.3 with SQLite3.51.3. No separate server,
+message queue, model call or scheduler is introduced. This PR does not migrate a
+running instance. Stop the instance, back up its private home, select the option,
+and restart through its existing host. General backend deployment remains #2189.
+
+## Commit boundary
+
+The existing save chain captures the full in-memory JSON-compatible snapshot and
+Effects watermark at call time. SQLite applies changed records, removed records,
+normalized histories and Effect intents in one `BEGIN IMMEDIATE` transaction.
+Unique record/history/change keys and a database commit-revision compare-and-set
+prevent stale snapshots from overwriting another writer. The original exclusive
+home lock remains required; a broken lock does not authorize SQL writes. A read-only
+host cannot acknowledge Effects. `projectEffects.saved` runs only after successful
+COMMIT, with no fallible database read between COMMIT and that acknowledgement.
+External execution remains after commit through existing adapters.
+
+WAL, synchronous FULL and foreign keys are configured and read back. Database and
+payload files are private; external credentials are not introduced. Actual process
+kill tests cover before-COMMIT rollback and after-COMMIT Task/Effect survival. They
+do not simulate physical power loss or guarantee a filesystem/device honors fsync.
+Use a local filesystem compatible with SQLite WAL, not a network-mounted database.
+See the [Node.js22.22.3 SQLite API](https://raw.githubusercontent.com/nodejs/node/v22.22.3/doc/api/sqlite.md),
+[SQLite synchronous settings](https://www.sqlite.org/pragma.html#pragma_synchronous)
+and [WAL constraints](https://www.sqlite.org/wal.html).
+
+## Layout and growth
+
+- `state.sqlite`: metadata, per-entity records, history rows and ordered change IDs.
+- `state_records`: namespace/ID primary key; immutable content hash and complete
+  record fingerprint. Root descriptors preserve empty maps and scalar values.
+- `state_history`: individual ordered entries for history, requirementsHistory,
+  waitHistory, results, roleSessionHistory, resumptions and versions arrays. A new
+  history item does not rewrite previous history items.
+- `state_changes`: monotonic sequence, commit revision, namespace/ID and operation;
+  no private record bodies. Its bounded internal query is not a public event feed.
+  Authenticated Project-scoped HTTP/events remain #2185.
+- `state-payloads/<sha256>.json`: immutable, hash-verified payloads above64KiB;
+  individual payloads are limited to16MiB. Files are fsynced before their transaction
+  can reference them. Failed commits may leave harmless unreferenced files; this
+  implementation does not automatically delete history or collect those files.
+- Existing logs, artifacts, SDK histories and workspaces stay in their existing
+  filesystem locations. Database records retain their references and hashes.
+
+Compatibility still hydrates the full runtime state. Each save scans/normalizes its
+snapshot and compares fingerprints; this is not constant-time or lazy SQL execution.
+It reduces changed disk records and separates append histories. History retention,
+in-memory residency and model context budgets are different concerns. Bounded
+role context, source retrieval and summary versions stay in #2177; changing the
+storage engine does not load all history into a model or solve context overflow.
+
+## Migration and one writable authority
+
+1. Validate the original JSON schema and ownership through the original Store,
+   applying its existing migrations and retaining identities. Invalid JSON or
+   ownership refuses migration; it cannot create an empty SQL replacement.
+2. Save a private immutable normalized import with SHA256. Atomically publish a
+   version3 `state.json` guard identifying the import and migration ID, phase
+   `prepared`. JSON-only older binaries refuse that newer version.
+3. Initialize state, schema and migration metadata in one SQL transaction. Verify
+   the DB/guard identity and activate the guard. Thereafter `state.json` is a guard,
+   not a second writable snapshot; omitting the option on restart still selects SQL.
+4. A prepared migration can recover from its verified import. A missing **active**
+   database refuses to import an old backup automatically. Foreign/future schema,
+   changed backup, wrong guard ID, invalid ownership or unknown authority fails closed.
+
+The current implementation migrates the complete original team state into one SQL
+transaction domain, including legacy users/Bots/rooms, Project records and pending
+Effects; it does not run JSON and SQL as independently writable partial stores.
+Working Task, Handoff, Attempt, SDK binding, logical Session and Effect IDs survive.
+An old read-only host taking over must refresh current SQL state; a stale raw save
+is rejected by revision instead of overwriting newer facts.
+
+## Private offline operator commands
+
+All hosts using this home must be stopped for export/rollback. The tool enforces the
+exclusive home lock; do not manually copy a live main DB and omit its WAL.
+
+```sh
+node core/scripts/state-storage.mjs inspect --home /private/flybot-home
+node core/scripts/state-storage.mjs export --home /private/flybot-home --migration MIGRATION_ID --output /private/export.json
+node core/scripts/state-storage.mjs rollback --home /private/flybot-home --migration MIGRATION_ID
+```
+
+Inspect returns metadata only. Use its exact migration ID as a stale-source guard.
+Export preserves the current committed version2 state in a private file, not the
+old import. Rollback keeps that export and archives DB/WAL/SHM together, atomically
+publishes the latest JSON state and completes a rollback marker. Remove the explicit
+`stateStorage: sqlite` option before restarting on JSON; otherwise it intentionally
+opts into a fresh SQL migration again. No authorization, evidence or history is reset.
+
+A prepared rollback blocks runtime writes and startup adoption. After interruption:
+
+```sh
+node core/scripts/state-storage.mjs rollback --home /private/flybot-home --migration MIGRATION_ID --resume
+```
+
+The tool checks the export hash, exact migration, archived paths and unchanged commit
+revision, completes partial moves and publishes JSON once. It will not overwrite a
+conflicting archive or silently revert newer SQL data. Current SQL writers also check
+the storage guard, so an old connection cannot keep writing after authority changes.
+The tool is not exposed to Bot roles or HTTP callers.
+
+## State semantics and release scope
+
+Existing authorized structured commands update formal facts deterministically.
+Queries derive views from those records; they do not call a model, rewrite Project
+goal/scope, or append to PROJECT.md/ROADMAP.md. Chief admission, dependency judgement
+and final completion remain the existing semantic decision points. Inspections keep
+their configurable scheduled-task policy. Summaries and human documents cannot
+replace permissions, execution ownership or matching candidate evidence.
+
+Comparison checked against upstream main986399246ff8c26bd418978785ce1199dbd239ca
+and delivery741bf1ef4aa199f0c7656095b32db3ab8e529a6a: main has the original core
+Store but not this delivery branch's Project development service or Effects module.
+The delivery base already had locked JSON snapshots and post-save Effects; it did
+not have SQLite. This issue's PR stacks on #2179/4826723cc and adds SQL storage and
+migration only. It does not merge upstream main, deploy, change control-plane/UI or
+claim real-provider parallel Task development validation. Public event/receipt and
+history service boundaries remain #2185; legacy entrypoint cutover remains #2186.

 ### 2026-11-03 — Migration must distinguish unfinished import from missing current data
 
 An interrupted prepared SQL migration may recover its verified import; an active database that disappears must fail closed, not silently revive the old import. Publish a newer-version JSON guard before initialization, validate one authority, and retain a fenced resumable rollback marker across partial moves. A transaction commit must precede Effects acknowledgement without a fallible post-commit read masking that proof.
+
+### 2026-11-03 — A failed acceptance save is not a valid retry result
+
+Pool acceptance previously left an active claim in memory when saving failed; repeating its idempotency key could return that uncommitted claim. Persist an acceptance marker, roll back failed ownership and require commit proof on replay. Public command replay must similarly bind exact intent/result and current principal while allowing the original successful generation to advance. Keep unknown outcomes explicit; receiving a fact does not grant initiative.

 ### 2026-11-03 — Transactional state (#2182)
 
 Opt-in SQL retains the original Store/services and saves domain facts plus Effects atomically. JSON becomes a newer-version migration guard, with verified import/recovery and offline export/rollback; no dual writable snapshots. Histories are normalized and large immutable payloads hash-referenced. Routine state updates/views make no additional model calls or Project-position changes. Full-state hydration/scanning remains; storage growth is distinct from #2177 context budgets. No live migration or provider-loop claim.
+
+### 2026-11-03 — Service contracts (#2185)
+
+The original application service adds private principal-scoped command receipts, bounded Task/Attempt sources, committed snapshots/events and authenticated resumable SSE. Unknown command outcomes are reconciled explicitly, never blindly rerun. Independent personal-agent identity survives carrier/transport rotation. Role acceptance commits before ownership can be replayed. Event receipt grants no role authority; private chat/auth/receipt writes do not affect public Project streams. Existing UI remains; #2186 compatibility and #2189 real deployment/README follow.

+
+```sh
+curl -N -H "x-flybot-member-session: $FB_SESSION" \
+  "$FB_URL/api/project-events?projectId=$FB_PROJECT"
+# Resume using the last accepted id from a snapshot/fact frame:

+  -H "Last-Event-ID: $FB_EVENT_CURSOR" \
+  "$FB_URL/api/project-events?projectId=$FB_PROJECT"
+```
+
+No token goes in a URL. The existing member header also accepts authenticated
+personal-agent credentials. Initial frames are snapshot, then fact with id cursors;
+deduplicate by cursor. access-revoked closes the stream; reset-required requires a
+fresh snapshot. Initial expired cursors receive HTTP409 with nextAction. No upstream
+owner cookie is forwarded. Current read rights are rechecked on each batch, including
+backpressure recovery. Project sequences exclude private conversations/auth/receipt
+writes. Default retention1024 facts/24h is configurable via projectEventRetention;
+it is not permanent audit history. Follow Task/Handoff/Attempt source queries for
+older records. See [full contract](subsystems/project-service-contracts.md).
+
+Operation names scope requestId, so different operations may reuse a key. When a key matches multiple operations, command.receipt/result require commandName (also supplied in resultRef); otherwise return bot/ambiguous-command. Retrying one invocation preserves its key; a deliberate new source.poll uses a fresh key. Confirmed replay preserves the original result and marks replayed:true, rather than rewriting its domain already flag.

 The original Store supports opt-in `stateStorage: sqlite` through the [storage bridge](project-state-storage.md). It retains the same runtime objects, save chain, Project services and home lock, and acknowledges Effects after actual SQL COMMIT. Locked JSON remains the default until selected; after migration the newer-version JSON guard fences old writers and SQL remains authoritative across configuration omission. Invalid migration never creates a fresh empty team. No extra model call or periodic task is introduced.

Failed saves publish nothing. Public snapshots/events omit private agent/auth/receipt data. Task construction stamps trusted command provenance once through the application context; body actor fields cannot forge it. The [contract](project-service-contracts.md) separates public requests, private receipts, host-only role authority and exact bounded history.

+# Commands, committed views and event transport
+
+The existing `project-development/v1` application boundary and `/api/bot` remain.
+There is no second Project, Task, identity, queue or executor. Public HTTP never
+accepts a role/Chief execution token; the existing trusted role ports own Handoff
+and adjudication. Consultation remains a separate message contract, not a Task.
+
+## Durable public commands
+
+The v1 command envelope requires a stable requestId. Receipts are scoped by operation, Project,
+user and independent personal-agent identity. Native watch and external connections
+for the same independent agent can recover the same receipt across carrier changes;
+legacy delegated carriers keep grant isolation. Origin is server-derived, never a
+body actor/session field. Human, personal-agent and Project-Chief origins differ.
+
+Canonical command intent includes operation, payload and supplied preconditions.
+Omitted candidate conditions differ from explicitly requiring no candidate. Changing
+intent under the same key returns `bot/idempotency-conflict`. A confirmed replay
+rechecks current authority and returns its recorded response even if the original
+generation has advanced. First dispatch checks current target/generation both before
+and after committing its begin marker. Concurrent requests share one invocation.
+
+Existing Effects commit intent, begin and result markers with receipt state. Result
+proof binds its SHA256. Failed intent cannot dispatch. A known result awaiting its
+final commit reports `completion-pending-commit`; retry finishes that commit without
+repeating the handler. Results above64KiB use immutable private hashed files, bounded
+to8MiB; exact reads reject symlinks, hash changes and foreign paths. `command.result`
+returns at most16000 characters with a hash guard. Result metadata/history remains
+outside default model context. Receipts are retained for recovery; automatic archival
+or garbage collection is not introduced here.
+
+A durable begin without a confirmed result is **unknown**, not permission to blindly
+repeat. Explicit reconciliation is limited to existing idempotent `task.run` and
+`task.propose`/`proposal.publish` recovery from their server-stamped original Task and
+committed intake proof. Reconstructed responses are labelled. Other ambiguous
+commands return `bot/outcome-unknown` with a receipt/target/Chief query suggestion.
+This is not a universal exactly-once external-side-effect guarantee. Existing domain
+adapters still reconcile their own external actions.
+
+`command.receipt` and `command.result` are private to the calling principal. Private
+command marker Effects are also excluded from other principals' list/retry views.
+Role acceptance separately commits `pool.accept`: failed saves restore the pending
+Handoff, retries cannot return an uncommitted claim, and current role operations
+require its committed acceptance proof. No new role execution is launched by a
+receipt marker or by receiving an event.
+
+## Bounded queries
+
+Task/Attempt read projections have explicit projectionVersion/preview markers.
+They retain current constraints, phase, provenance and evidence metadata, not entire
+requirements/wait/result/session histories. No execution-requester Session appears
+in Task summaries. Existing UI-consumed fields remain; unbounded raw-record clients
+must follow source references rather than depend on removed historical payloads.
+Original stored records and logical/physical execution Sessions are not truncated.
+
+- `task.history`: requirements, requirement versions, admission decisions, dependency
+  results, wait history, final results, handoffs, notes and actor history.
+- `attempt.context`: existing role contexts plus exact evidence, feedback,
+  requirement, failure, role definitions and integration-admission sources.
+- Exact sources are Project/Task scoped, max16000 characters, with SHA256 and
+  expectedSha256/offset guards. Unknown sections/foreign targets are refused.
+- Attempt pages remain max50. Repeated role Session previews show the latest three,
+  retaining references to complete original sources. Persona, full logs and tool
+  transcripts do not ride on every Task detail response.
+
+## Committed event model
+
+The original Store prepares safe Project/Task/Attempt/execution/resource/input
+projections inside its serialized immutable-snapshot write. It persists changed
+facts and cursor metadata in the same JSON rename or SQLite transaction as business
+state/Effects. Only after that commit does it acknowledge the event read model.
+A failed save cannot publish an event or a newer committed snapshot.
+
+Each Project has its own epoch, sequence and revision. Private chat, unpublished
+proposals, personal memory, credentials and command-receipt writes do not perturb
+its public sequence. Event data includes bounded public metadata/ref IDs; no raw
+operator configuration, auth Session, tool transcript or private conversation.
+Permissions are checked on every query and transport batch. Events describe stored
+facts, not proof of live process activity or authority to execute a command.
+
+`project.snapshot` returns a bounded committed Project/Task projection with cursor
+and revision. Further Task pages require expectedRevision; changed snapshots must
+restart. `events` reads after a Project-scoped cursor, max100. Defaults retain1024
+facts per Project and24hours, configurable through `projectEventRetention` with
+maxPerProject and maxAgeMs. Clock rollback cannot create a hole; duplicate/gapped
+persisted streams fail closed. Age/size expiry or a different epoch returns
+`bot/cursor-expired` and `nextAction: project.snapshot`. SSE is not permanent history;
+Task/Handoff/Attempt queries retain the original history. Delivery is at least once;
+clients deduplicate by cursor and query current state when uncertain.
+
+## HTTP/SSE
+
+`GET /api/project-events?projectId=PROJECT_ID` on the existing restricted gateway
+requires `x-flybot-member-session`, accepting the existing user or personal-agent
+credential. Tokens in URLs are refused. Initial connection emits a bounded snapshot;
+Last-Event-ID (or an unambiguous after query parameter) resumes committed facts.
+No DSH owner cookie, Set-Cookie or raw DSH event stream is forwarded to the client.
+
+SSE uses authenticated original application queries. Connection-bound polling is
+transport only, not a Chief inspection/work timer. Factory options eventPollMs
+(default1000) and eventMaxStreams(default64) bound it; the gateway CLI exposes
+--event-poll-ms and --event-max-streams. Backpressure reauthenticates before another
+batch, revocation closes the stream, and server shutdown/disconnect aborts polling.
+Initial errors use HTTP401/403/409/429 as appropriate. An established stream sends
+access-revoked or reset-required and closes; clients must act rather than reconnect
+forever with an expired cursor.
+
+Tests distinguish actual TCP/SQLite/process operations from fixture authorization
+and deterministic inference. This stage does not claim an external grok/dots provider
+or full real-SDK parallel development acceptance. Compatibility cutover is #2186;
+simplified real backend deployment/README remains #2189. No control-plane/UI rewrite,
+new autonomous worker, inspection timer, deployment or merge is performed.
+
+Operation names scope requestId, so different operations may reuse a key. When a key matches multiple operations, command.receipt/result require commandName (also supplied in resultRef); otherwise return bot/ambiguous-command. Retrying one invocation preserves its key; a deliberate new source.poll uses a fresh key. Confirmed replay preserves the original result and marks replayed:true, rather than rewriting its domain already flag.

Subject: [PATCH 13/21] Require approved durable Project role changes

Keep Chief proposals separate from Maintainer and Owner approval. Preserve retired role context and room history without reassigning existing Tasks or inferring worker exit.

+## Project role governance (#2171)
+
+The active catalog starts with Chief, Developer, Tester and Reviewer. Its logical role
+key is distinct from its human permissions and execution `policyRole`. Up to 32 active
+roles can inherit developer/tester/reviewer conventions; only the resident Chief can
+have Chief capability. `deliveryDefinitions` reports the catalog revision for execution
+pinning. Definition changes never replace a Task's already pinned execution context.
+
+A current resident Chief can use `project_agent_role_propose` with
+`{requestId,action:add|update|remove,role,reason,fields}`. The host derives Project,
+initiating human and actual delegation; no HTTP actor fields grant Chief authority.
+A validated scheduled Chief result can instead include up to four `roleProposals`.
+Both paths only publish a pending durable proposal. Chief cannot approve itself,
+including through an Owner's watch grant. A private agent with current full watch
+permission retains that human's approval authority; safe agents cannot approve.
+
+`project-roles {projectId}` returns bounded catalog metadata. Add `role` for exact
+JSON source pages (`offset`, `limit` up to 16000, optional `expectedSha256`).
+`project-role-proposals {projectId,limit,after}` pages pending/decided metadata;
+`proposalId` selects an exact proposal and proposed definition. Current Project
+members can read these shared role records. Approval uses
+`project-role-decision {projectId,proposalId,expectedSha256,requestId,decision}`
+with `approve|reject`; only current Maintainer/Owner configure authority is accepted.
+Approval requires the published body hash and unchanged base catalog revision,
+revalidates Skills/memory/resource references, then commits the decision and catalog
+change with an Effects marker. Exact repeated decisions do not advance revision.
+Direct human `project-agent-definition` updates retain the same validation/audit
+boundary and invalidate older pending proposals. Instructions exceeding 12000
+characters fail explicitly instead of being silently truncated.
+
+Pending or failed commits are not execution-visible. After failed saves, queued
+snapshots settle before rollback so an already committed decision is not undone or
+an uncommitted approval resurrected. Histories live in `projectRoleChanges`, proposals
+in `projectRoleProposals`, and retired definitions in `projectRetiredRoles`, separate
+from the small active catalog. Removing Chief is refused. Retirement preserves Task
+ownership, worker/Session records and room history; it does not transfer initiative,
+stop a process or claim exit. A later approved add of the same key inherits its last
+retired capability/conventions unless the proposal explicitly changes them. New room
+messages to a retired role fail visibly; historical rooms remain readable.
+
+These governance tests use real host APIs/Store plus deterministic Bot carriers and
+Effects fault fixtures, not a real model. Custom-role physical execution and in-flight
+revocation acceptance remain in #2184; this catalog alone does not prove that loop.

 Project convergence #2171 admits the six repository/closure endpoints through the restricted gateway. Each reaches the same domain service with authenticated membership and operation-specific authority; exposing a route does not grant configure or Owner confirmation rights.

Subject: [PATCH 14/21] Require native execution quiescence before releasing
 Task context

Keep exact latest Task-role native bindings and context parts, refuse unknown exit and missing handles, and use committed role catalogs when pinning execution rights. Preserve original Workflow lifecycle and legacy DAG workspace behavior.

 Native Task-role continuation, unified public receipts/events (#2185), transactionally

+
+
+## Native physical Session binding and quiescence (#2184)
+
+The original Workflow lifecycle still owns native Bot creation, dispatch and removal.
+Its registered-Workspace host adapter now records `projectNativeWorkers` and a
+`native-session/v1` binding on the existing Task-role logical Session. This is adapter
+metadata, not a second executor. A fresh ephemeral Bot may bind only the latest exact
+native physical Session after prior execution is quiescent, the old Bot is gone and
+its resource lease is released. Project/Task/role, cwd, model, definition fingerprint
+and resource must match. New native parts retain previous segments; tombstoned Bot
+IDs are never resurrected. A saved legacy native Session without a trusted binding
+fails with explicit recovery instead of silently starting over.
+
+Removal first fences new input, requests cancellation through the existing resolved
+DSH Agent, and awaits `whenIdle()` before recording `native-agent-quiescent` with
+worker, latest physical Session, binding key and generation. Bot absence and a bare
+`exited` flag are not proof. A stop failure keeps visible `stop-unconfirmed` state and
+capacity held. A process-local host epoch prevents accidentally resuming an unknown
+old-host worker merely to cancel it. Quiescence survives restart as a recorded fact;
+unknown old-host executions still require actual prior-exit reconciliation. No timeout
+fabricates exit. Stop acknowledgement alone cannot release a native lease.
+
+Native continuation rechecks the live pool claim, initiating human/delegation, role
+permissions and resource before and after asynchronous Session loading. Overlapping
+binds for one Task-role cannot attach two carriers. Canonical pool rework may retain
+the same physical worktree only after matching native quiescence and released leases;
+legacy DAG workspace rules remain separate. Existing Task definitions remain pinned,
+but a removed role or changed execution capability cannot restart under stale rights.
+Approved custom role keys have distinct logical Session IDs; default-role fingerprints
+remain compatible while a nondefault capability class participates in the fingerprint.
+
+Actual DSH delivery acceptance checks all three native roles' quiescence proofs before
+removal, actual code edits/host tests, and credential refusal; inference is deterministic.
+Factory tests cover exact restoration/parts, concurrency, stale claims, model/cwd changes
+and unknown exit. They do not establish a real-provider canonical pool return loop.
+Custom-role artifact verification, native crash reconciliation, in-flight capability
+revocation and the final composed service acceptance remain tracked under #2184.
+The public native-resume capability remains conservative until the whole loop is tested.

Implementation/test/review evidence records its producer and role Session. Artifact sealing, host tests, Review, publication/retry and SDK proof validation resolve those assignments; no duplicate Workspace aliases or rewritten historical records are introduced. Historical Attempts without assignments retain default-role behavior. A custom Developer gets its own local branch while the canonical publication branch remains stable.

Subject: [PATCH 16/21] Activate exact native context before resuming pool
 handoffs

Preserve structured handoff identity through native delivery and restore archived context only after committed activation. Guard the actual DSH single-resource return path and keep historical implementation evidence outside the bounded active policy.

-before each pool receiver and after independent test cleanup. Failed allocation,
-checkout or context preparation releases only proven unbound reservations and
-retains its failure audit. These changes do not imply live UI or R8 acceptance.
-
-
-This is `zy95-12/FlyBot`. Current scope is the [shared-project roadmap](https://github.com/zy95-12/FlyBot/issues/1)
-and [fork decision](decisions/2026-10-31-project-first-fork.md). The inherited mission,
-people and stage descriptions below are historical upstream context; upstream accounts
-are not this fork's decision-makers merely because inherited docs name them.
-
-- Project is the target stable boundary for Task/Run/Workspace ownership. Bots and
-  Sessions are replaceable execution/interaction carriers. M1 implements direct ownership and explicit legacy resolution; see [Project domain](docs/subsystems/project-domain.md).
-- Reuse control-plane identity, auth, invitation, instance and operations APIs unchanged
-  where possible. Put project business logic/adapters in FlyBot; justify a missing API
-  separately. The platform PR was withdrawn, not merged.
-- Rebuild task navigation and the Project board; current UI/components are not constraints.
-- M0 is implemented on [PR #9](https://github.com/zy95-12/FlyBot/pull/9), merged (2026-10-31):
-  real DSH/tool execution with a deterministic model, plus a FlyBot-owned HTTP adapter
-  exercising unchanged external platform source. This is not real-model PR delivery.
-- The baseline identity, scoped Workflow-write and per-run cwd seams are implemented
-  through M1–M3; later milestone integration and live acceptance are recorded below.
-- Durable repository memory is this page, ROADMAP, LESSONS and dated decisions. Update
-  them and matching architecture docs alongside code, with regression coverage in
-  verify/CI and tested-SHA evidence. Never edit live DSH/Bot memory for repository decisions.
-
-See [baseline ownership and tests](docs/subsystems/demo-baseline.md).
-
-- M1 implementation ([PR #10](https://github.com/zy95-12/FlyBot/pull/10), complete local verification, awaiting review) adds Project service/policy/repository boundaries, immutable work
-  ownership, explicit migration, archive/delete/member-removal rules and an owner-only
-  detail API. Workspace records are directory references; M3 supplies worktree isolation.
-- The owner authorized continuing M2–M6, one PR per milestone, with memory, architecture
-  and tests updated in each. [M1 decision](decisions/2026-10-31-m1-project-ownership.md).
-
-- M2 ([PR #11](https://github.com/zy95-12/FlyBot/pull/11), complete local verification, awaiting review) implements the [shared access contract](docs/subsystems/project-access.md): unchanged
-  platform auth API adapter, stable subject mapping, human membership policy/invites,
-  immediate revocation and scoped Workflow gateway. It is explicitly configured; worktrees,
-  agent delegation/credentials and browser delivery are supplied by M3–M6 below.
-
-- M3 ([PR #13](https://github.com/zy95-12/FlyBot/pull/13), full local verify) implements the [commit-specific delivery contract](docs/subsystems/project-delivery.md)
-  on the existing Workflow service: versioned Attempts, real role worktrees/cwd, host test
-  evidence, Review/SHA gates and human acceptance. Actual DSH and draft artifact PR #12
-  were first exercised with a deterministic model. Integrated real-model/GitHub/browser
-  acceptance subsequently passed in M6; [evidence](docs/live-acceptance.md).
-
-- M4 implements [scoped Project agents](docs/subsystems/project-agents.md): fresh public
-  Chief, private human/Project identities, separate memory/history/proposals, live delegated
-  tool checks, role/skill snapshots and exact GitHub credential scopes. Actual DSH fixture
-  validation covers creation/publication/revocation; real-model/browser acceptance
-  subsequently passed in M6. Runtime code-worker OS isolation is not claimed by this demo.
-
-- M7 is owner-authorized in [#20](https://github.com/zy95-12/FlyBot/issues/20),
-  implemented sequentially as #21–#25, one PR per issue. It explicitly authorizes native,
-  Codex SDK and Claude Agent SDK Harness choices; the inherited upstream removal of
-  Codex does not govern this fork. Control-plane remains unchanged. M7.1 introduces
-  explicit public role memory and bounded hashed execution contexts, durable Chief
-  identity/history and per-Attempt temporary Session bindings. M7.2–M7.5 code is on PRs #27–#30: resource leases, SDK Harnesses, Owner setup and
-  verified Git handoffs. Authenticated mixed-resource acceptance remains outstanding;
-  the later owner-authorized local Codex-only run passed, as recorded below.

 ### Task-scoped SDK context and resident Chief memory — 2026-11-01
-Owner requires a resident Chief with durable Project memory and one logical Session per Task/role. Codex/Claude own their supported conversation persistence and automatic compaction; FlyBot does not inject a second model-history compactor. SDK role rework reuses a confirmed released Task-role cwd/thread under the same principal/resource/profile/model/persona binding, while preserving separate immutable Attempt/claim/log/test/Review evidence. Changed bindings rotate backend threads with recorded lineage. Chief memory uses the original own-Bot MEMORY.md/topics/journal, never global team or private-user memory. Context admission keeps current bounded facts and hash-bound full source archives for scoped retrieval. Backend changes are foreground work; frontend Task40/PR48 resumes through FlyBot after validation.
-
-Task40 continuation integrates trusted backend `91792c1b` into preserved candidate
-`25607404` without committing or publishing. Room-scoped messages/streaming and role
-identity are retained alongside Chief retrieval/memory and binding-checked SDK resume.
-The inherited changelog failure reproduces (6/7) and the single-entry repair passes
-(7/7). Generated patches match canonical core. Direct integration testing requires
-DSH's registered loader: plain node cannot resolve `@deepseek-ai/dsh-llm` from the
-new scheduled-task module. This is not a passing integration result. Native composer,
-tool/approval/stop/stream, personal/group interactions, CSS-load synchronization and
-actual deployed three-account/weak-network acceptance remain open.
-
-Follow-up local check used the required harness loader:
-`cd core && node --import ./test/harness-resolve.mjs --test test/project-agents.test.js test/project-harness.test.js`
-passed 40/40 on the staged merge draft. The earlier plain-node failure was a loader
-invocation error, not a missing prepared dependency. Full verify, smoke, independent
-Review and deployed acceptance are Not run for this draft.
-
-Task40 adds a CSS/JS readiness barrier (defect tests 0/2 → 2/2) and mounts the scoped
-composer from original composer.js for Project agents and personal conversations.
-The original dictation hook is reused with disposal; captured chat handles retain
-scope revocation. A base-bundle composer test fails because the capability is absent;
-current native render/client/asset checks pass 27/27. These are local draft checks,
-not host full verification, independent Review or deployed three-account acceptance.
-
-The room composer now shares that native mount and existing registered-document
-IDs, while personal groups restrict mention choices to their visible members.
-Actual native workText labels render scoped live tool names. Final focused UI
-checks pass 33/33. Full verify was attempted during editing and is not valid final

-Task40 continuation at base cbcad4c4 adds actual native question/approval/stop/continue
-controls, original group MemberWork controls, bounded redacted tool results and current
-own-chat streaming. Existing original components are reused; standing grants and raw
-owner APIs are not exposed. SDK permission/message inputs now use the same original
-approval/composer components with existing host worker-generation/current-rights gates.
-The new personal HTTP capability test failed at base (1/2) before implementation and
-passed afterward; additional boundary tests cover foreign approvals/workers, retired
-handles, hidden turns, historical parts and stale questions. Host full verification,
-independent Review and deployed three-account/weak-network screenshots remain required.
-
-The continuation also restores answerable group question/approval cards through
-original handlers, exposing only public question fields rather than replyTo/origin.
-Group member-stop tests use actual native membership and reject another owner's Bot.
-Final local interaction checks, build/patch/lint results and outstanding host/browser
-validation are reported at handoff; no candidate recommendation closes this Task.
-
-Task40 host verification at `33e482d6` reported four failures in install, secrets
-and usage suites. All four reproduced locally (28/32). The personal stream observer
-was also installed in legacy mode, shifting the established listener order used by
-those protocol tests. Register it only for explicit shared-workbench mode; keep its
-purpose/Session guards. The new mode-boundary regression fails without that fix;
-affected suites plus personal-workbench coverage now pass 38/38. Final host full
-verification and independent Review remain required; no deployed acceptance is claimed.
-
-Review return at `846378bf` reproduced current-part navigation leaving the live
-conversation read-only; picker and explicit current-part links now normalize to the
-live route (defect regression red→green). Human Markdown/mentions reuse original
-PersonMessage. Attachment-only messages, scoped image preview/file download and
-native file/image sends use public DSH attachment/Agent APIs with current-user checks.
-The new human/attachment render test fails against the base bundle and passes on the
-working build. Boundary tests cover foreign IDs, batch validation, historical reads,
-revocation during admission and late download callbacks. Final host verification,
-independent Review and real-service screenshots/weak-network acceptance remain open.
-
-Review return at `bde2cf7c` reproduced native composer remount/focus loss on same-route
-refresh. The mounted regression now uses bounded boolean DOM-identity diagnostics
-(the former object diff exhausted memory before reporting failure) and reproduces
-red at that source. Native roots now update in place within the same scoped route and
-source, retaining input, cursor and focus; navigation/revocation still dispose them.
-Mounted personal/public/private/room regressions cover retained sends and scope teardown.
-No resource limit was raised. Exact-candidate host verification, independent Review
-and deployed three-account/weak-network/screenshot acceptance remain separate gates.

+# Historical backend execution evidence
+
+Archived verbatim from PROJECT.md on 2026-11-03 to keep the active role-policy context bounded. These dated implementation/probe records retain their original claims and limitations; current owner decisions and PROJECT.md govern current behavior and permissions. No active operating rule or test budget is removed.
+
+### Direct backend recovery — 2026-11-01
+
+The owner requires backend repairs in the foreground Codex session; do not
+dispatch backend development through FlyBot. Existing frontend work is preserved and now continues autonomously while new
+backend service work is developed independently (owner update, 2026-11-01). See the
+[execution decision](decisions/2026-11-01-direct-backend-recovery.md).
+R6 adds coalesced event-driven dispatch, manager-controlled retry of blocked queue
+entries under the original requester, and operator-selected workspace preparation
+before each pool receiver and after independent test cleanup. Failed allocation,
+checkout or context preparation releases only proven unbound reservations and
+retains its failure audit. These changes do not imply live UI or R8 acceptance.
+
+
+This is `zy95-12/FlyBot`. Current scope is the [shared-project roadmap](https://github.com/zy95-12/FlyBot/issues/1)
+and [fork decision](decisions/2026-10-31-project-first-fork.md). The inherited mission,
+people and stage descriptions below are historical upstream context; upstream accounts
+are not this fork's decision-makers merely because inherited docs name them.
+
+- Project is the target stable boundary for Task/Run/Workspace ownership. Bots and
+  Sessions are replaceable execution/interaction carriers. M1 implements direct ownership and explicit legacy resolution; see [Project domain](docs/subsystems/project-domain.md).
+- Reuse control-plane identity, auth, invitation, instance and operations APIs unchanged
+  where possible. Put project business logic/adapters in FlyBot; justify a missing API
+  separately. The platform PR was withdrawn, not merged.
+- Rebuild task navigation and the Project board; current UI/components are not constraints.
+- M0 is implemented on [PR #9](https://github.com/zy95-12/FlyBot/pull/9), merged (2026-10-31):
+  real DSH/tool execution with a deterministic model, plus a FlyBot-owned HTTP adapter
+  exercising unchanged external platform source. This is not real-model PR delivery.
+- The baseline identity, scoped Workflow-write and per-run cwd seams are implemented
+  through M1–M3; later milestone integration and live acceptance are recorded below.
+- Durable repository memory is this page, ROADMAP, LESSONS and dated decisions. Update
+  them and matching architecture docs alongside code, with regression coverage in
+  verify/CI and tested-SHA evidence. Never edit live DSH/Bot memory for repository decisions.
+
+See [baseline ownership and tests](docs/subsystems/demo-baseline.md).
+
+- M1 implementation ([PR #10](https://github.com/zy95-12/FlyBot/pull/10), complete local verification, awaiting review) adds Project service/policy/repository boundaries, immutable work
+  ownership, explicit migration, archive/delete/member-removal rules and an owner-only
+  detail API. Workspace records are directory references; M3 supplies worktree isolation.
+- The owner authorized continuing M2–M6, one PR per milestone, with memory, architecture
+  and tests updated in each. [M1 decision](decisions/2026-10-31-m1-project-ownership.md).
+
+- M2 ([PR #11](https://github.com/zy95-12/FlyBot/pull/11), complete local verification, awaiting review) implements the [shared access contract](docs/subsystems/project-access.md): unchanged
+  platform auth API adapter, stable subject mapping, human membership policy/invites,
+  immediate revocation and scoped Workflow gateway. It is explicitly configured; worktrees,
+  agent delegation/credentials and browser delivery are supplied by M3–M6 below.
+
+- M3 ([PR #13](https://github.com/zy95-12/FlyBot/pull/13), full local verify) implements the [commit-specific delivery contract](docs/subsystems/project-delivery.md)
+  on the existing Workflow service: versioned Attempts, real role worktrees/cwd, host test
+  evidence, Review/SHA gates and human acceptance. Actual DSH and draft artifact PR #12
+  were first exercised with a deterministic model. Integrated real-model/GitHub/browser
+  acceptance subsequently passed in M6; [evidence](docs/live-acceptance.md).
+
+- M4 implements [scoped Project agents](docs/subsystems/project-agents.md): fresh public
+  Chief, private human/Project identities, separate memory/history/proposals, live delegated
+  tool checks, role/skill snapshots and exact GitHub credential scopes. Actual DSH fixture
+  validation covers creation/publication/revocation; real-model/browser acceptance
+  subsequently passed in M6. Runtime code-worker OS isolation is not claimed by this demo.
+
+- M7 is owner-authorized in [#20](https://github.com/zy95-12/FlyBot/issues/20),
+  implemented sequentially as #21–#25, one PR per issue. It explicitly authorizes native,
+  Codex SDK and Claude Agent SDK Harness choices; the inherited upstream removal of
+  Codex does not govern this fork. Control-plane remains unchanged. M7.1 introduces
+  explicit public role memory and bounded hashed execution contexts, durable Chief
+  identity/history and per-Attempt temporary Session bindings. M7.2–M7.5 code is on PRs #27–#30: resource leases, SDK Harnesses, Owner setup and
+  verified Git handoffs. Authenticated mixed-resource acceptance remains outstanding;
+  the later owner-authorized local Codex-only run passed, as recorded below.
+
+### Task-scoped SDK context and resident Chief memory — 2026-11-01
+Owner requires a resident Chief with durable Project memory and one logical Session per Task/role. Codex/Claude own their supported conversation persistence and automatic compaction; FlyBot does not inject a second model-history compactor. SDK role rework reuses a confirmed released Task-role cwd/thread under the same principal/resource/profile/model/persona binding, while preserving separate immutable Attempt/claim/log/test/Review evidence. Changed bindings rotate backend threads with recorded lineage. Chief memory uses the original own-Bot MEMORY.md/topics/journal, never global team or private-user memory. Context admission keeps current bounded facts and hash-bound full source archives for scoped retrieval. Backend changes are foreground work; frontend Task40/PR48 resumes through FlyBot after validation.
+
+Task40 continuation integrates trusted backend `91792c1b` into preserved candidate
+`25607404` without committing or publishing. Room-scoped messages/streaming and role
+identity are retained alongside Chief retrieval/memory and binding-checked SDK resume.
+The inherited changelog failure reproduces (6/7) and the single-entry repair passes
+(7/7). Generated patches match canonical core. Direct integration testing requires
+DSH's registered loader: plain node cannot resolve `@deepseek-ai/dsh-llm` from the
+new scheduled-task module. This is not a passing integration result. Native composer,
+tool/approval/stop/stream, personal/group interactions, CSS-load synchronization and
+actual deployed three-account/weak-network acceptance remain open.
+
+Follow-up local check used the required harness loader:
+`cd core && node --import ./test/harness-resolve.mjs --test test/project-agents.test.js test/project-harness.test.js`
+passed 40/40 on the staged merge draft. The earlier plain-node failure was a loader
+invocation error, not a missing prepared dependency. Full verify, smoke, independent
+Review and deployed acceptance are Not run for this draft.
+
+Task40 adds a CSS/JS readiness barrier (defect tests 0/2 → 2/2) and mounts the scoped
+composer from original composer.js for Project agents and personal conversations.
+The original dictation hook is reused with disposal; captured chat handles retain
+scope revocation. A base-bundle composer test fails because the capability is absent;
+current native render/client/asset checks pass 27/27. These are local draft checks,
+not host full verification, independent Review or deployed three-account acceptance.
+
+The room composer now shares that native mount and existing registered-document
+IDs, while personal groups restrict mention choices to their visible members.
+Actual native workText labels render scoped live tool names. Final focused UI
+checks pass 33/33. Full verify was attempted during editing and is not valid final
+verification; a later process-control/result request was refused by sandbox
+loopback policy. Request actual configured host verification through Tester, then
+return this partial implementation to Developer for remaining tool-result,
+approval, personal live/stop and full interaction work. Do not close Task40.
+
+Task40 continuation at base cbcad4c4 adds actual native question/approval/stop/continue
+controls, original group MemberWork controls, bounded redacted tool results and current
+own-chat streaming. Existing original components are reused; standing grants and raw
+owner APIs are not exposed. SDK permission/message inputs now use the same original
+approval/composer components with existing host worker-generation/current-rights gates.
+The new personal HTTP capability test failed at base (1/2) before implementation and
+passed afterward; additional boundary tests cover foreign approvals/workers, retired
+handles, hidden turns, historical parts and stale questions. Host full verification,
+independent Review and deployed three-account/weak-network screenshots remain required.
+
+The continuation also restores answerable group question/approval cards through
+original handlers, exposing only public question fields rather than replyTo/origin.
+Group member-stop tests use actual native membership and reject another owner's Bot.
+Final local interaction checks, build/patch/lint results and outstanding host/browser
+validation are reported at handoff; no candidate recommendation closes this Task.
+
+Task40 host verification at `33e482d6` reported four failures in install, secrets
+and usage suites. All four reproduced locally (28/32). The personal stream observer
+was also installed in legacy mode, shifting the established listener order used by
+those protocol tests. Register it only for explicit shared-workbench mode; keep its
+purpose/Session guards. The new mode-boundary regression fails without that fix;
+affected suites plus personal-workbench coverage now pass 38/38. Final host full
+verification and independent Review remain required; no deployed acceptance is claimed.
+
+Review return at `846378bf` reproduced current-part navigation leaving the live
+conversation read-only; picker and explicit current-part links now normalize to the
+live route (defect regression red→green). Human Markdown/mentions reuse original
+PersonMessage. Attachment-only messages, scoped image preview/file download and
+native file/image sends use public DSH attachment/Agent APIs with current-user checks.
+The new human/attachment render test fails against the base bundle and passes on the
+working build. Boundary tests cover foreign IDs, batch validation, historical reads,
+revocation during admission and late download callbacks. Final host verification,
+independent Review and real-service screenshots/weak-network acceptance remain open.
+
+Review return at `bde2cf7c` reproduced native composer remount/focus loss on same-route
+refresh. The mounted regression now uses bounded boolean DOM-identity diagnostics
+(the former object diff exhausted memory before reporting failure) and reproduces
+red at that source. Native roots now update in place within the same scoped route and
+source, retaining input, cursor and focus; navigation/revocation still dispose them.
+Mounted personal/public/private/room regressions cover retained sends and scope teardown.
+No resource limit was raised. Exact-candidate host verification, independent Review
+and deployed three-account/weak-network/screenshot acceptance remain separate gates.

 #2184 extends the original actual-DSH delivery probe to inspect persisted native-agent-quiescent proofs for Developer, Tester and Reviewer before removal. It keeps deterministic inference and the existing real code edit, configured host tests, missing-credential refusal and disposable cleanup assertions; this is not a real-provider or canonical return-loop acceptance.

+`node dev/demo/run.mjs --native-pools` adds actual DSH single-resource Developer/Tester return/context restoration acceptance with a deterministic model. The marker is emitted only into the first Developer conversation outside the durable handoff JSON; the second request must find it in retained history, absent fresh system/input. It verifies fresh carriers, same physical Session/cwd, actual second code revision/host tests, lease intervals and Chief arbitration without fake closure; cleanup stops its disposable Attempt and removes worktrees. The required runtime suite now includes this fifth case. Initial failures exposed implicit [object Object] delivery deduplication and DSH archived-session admission; retained private evidence distinguishes both from the passing probe.

 New v7/pools-v4 Attempts distinguish logical role keys from developer/tester/reviewer capability classes. `roleAssignments` maps each artifact responsibility to the actual logical producer; Workspaces, Sessions, leases and execution evidence remain keyed by that logical role. Implementation/test/review evidence records its producer and role Session. Artifact sealing, host tests, Review, publication/retry and SDK proof validation resolve those assignments; no duplicate Workspace aliases or rewritten historical records are introduced. Historical Attempts without assignments retain default-role behavior. A custom Developer gets its own local branch while the canonical publication branch remains stable. The artifact-controller regression uses actual Git edits, configured host tests and a labelled fixture publisher; it does not claim signed Review or a whole bot loop.

+Native host creation now prepares the exact context binding, invokes the existing Session/resource bind, then activates through a committed native.activate Effects marker. This orders all lease/carrier/Session metadata before archive admission or model input. The existing pre-step middleware closes startup/inbox bypasses for uncommitted or obsolete native bindings; ordinary Bots are unaffected.

 and unknown exit. They do not establish a real-provider canonical pool return loop.
 Custom-role artifact verification, native crash reconciliation, in-flight capability
 revocation and the final composed service acceptance remain tracked under #2184.
-The public native-resume capability remains conservative until the whole loop is tested.
+The capability query now advertises native Task-role resume and native-agent-quiescence exit confirmation for exact supported bindings; unknown exit still refuses continuation.
 
 
 Approved custom roles now pin `policyRole` on their Session and SDK worker record. Native/SDK Workspace ownership accepts an approved capability while preserving logical role identity. Codex writable roots and SDK readOnly derive from the pinned capability, not a literal Bot name. Repository source overrides prefer the logical role and otherwise inherit its capability's complete rules; the custom policy hash records both, while default policy bytes remain compatible. SDK subprocess contract tests inspect actual transmitted readOnly settings for a custom Developer and Reviewer; they are deterministic workers, not provider execution.
+
+
+The actual DSH `--native-pools` probe now executes Developer → Tester return → original Developer → Tester → Chief inbox with one native resource. It verifies a fresh carrier restores the same physical Session/cwd and a marker present only in the prior conversation, two real code revisions, configured host tests and nonoverlapping released leases. Exact restoration explicitly unarchives the prior Session through the existing Workspace registry after the new binding is saved; DSH otherwise rejects archived Sessions before their first model step. The unused fresh carrier Session remains managed/tombstoned. Inference is deterministic; Chief closure/provider/forge completion are not claimed.
+
+
+Native activation is separate from provisional binding. After the original Session bind
+records the native resource worker, `native.activate` stages and persists an Effects
+marker with the exact Task/Attempt/Session/binding/generation. Only confirmed commit
+allows input or lifts archive admission. A resolving noncommitting save is not evidence;
+its regression leaves the old Session archived and native input fenced. The existing
+DSH pre-step hook also rejects unactivated, previous-host-epoch, stopping/released or
+read-only native work, including startup/inbox paths that bypass ordinary delivery.
+Unrelated personal Chief/group Bots retain their original admission behavior. No new
+executor or polling timer is involved. Current-role in-flight abort/reconciliation and
+unknown old-host exit remain separate tracked acceptance.

 Repair R3 (#36): Project task pools now enforce the existing pure handoff validator via the trusted host adapter and reuse spawn/dispatch/release and result interception. New Project deliveries do not instantiate a static Workflow graph. `projectDispatch: workflow` retains explicit legacy graph execution and fixtures. See [pool contract](project-pools.md).
+
+
+#2184 fixes native lifecycle input delivery: structured inputs use JSON rather than implicit [object Object] conversion, preserving handoff IDs/evidence and false/zero values. Distinct returned handoffs therefore produce distinct content for the existing delivery deduplicator, while an exact repeated dispatch remains stable. The regression uses the original plugin lifecycle seam; the real DSH native-pool probe reproduces and guards same-Session return delivery. No alternate Workflow or scheduler is introduced.

+Seen 1× (actual pool adapter regression). Resource release had stopped trusting Bot
+absence, but its caller still returned exitConfirmed=true for an unknown missing Bot.
+Use one proof query at the initiative boundary too. Native Agent idle also excludes
+background jobs: stop/query registered work across earlier parts and child lineage,

+facts without auto-resuming an old worker or confusing a reused PID with ownership.

+## Physical exit and host recovery (#2184)
+
+The actual pool host adapter now asks the shared execution-exit checker after release;
+a missing Bot/unknown worker alone cannot transfer execution authority. SDK facts use
+the existing confirmed-worker-exit contract plus a released lease. Native facts use the
+matching quiescence record and released lease, or a persisted verified supervisor
+process-group exit for a legacy lease. Physical exit does not invent recoverable context.
+
+New `project-native-worker/v2` records capture the existing host process scope even
+without an explicit resource. Normal exit requests all registered work to stop, waits
+for Agent idle, and checks Workspace activity for current/earlier context parts and
+known subagent Sessions. Idle-child background jobs still block release. Native pre-step
+admission follows durable subagent lineage and records its Session IDs; an obsolete or
+unactivated ancestor cannot resume through a child. Missing legacy execution bindings
+are fenced, while ordinary personal Chiefs/groups retain their original behavior.
+Registered work still stopping leaves bounded kind/count facts and held capacity;
+no timeout fabricates exit. The existing Task/Chief retry path can recheck after actual
+work has settled. This is registered-platform work proof in the trusted host profile,
+not a claim of adversarial OS isolation.
+
+For a previous host epoch, native stop never resumes an old Agent to infer safety.
+It reuses `priorScopeExited` with the exact recorded systemd control-group/invocation
+and validates lease/worker/generation before and after inspection. Matching proof
+preserves latest context parts and updates the exact Attempt role Session metadata.
+Unknown/unmanaged groups, missing/latest context or changed binding remain held.
+Capacity may be released from an actually verified legacy supervisor fact while
+context restoration still refuses an unknown binding. Reconciliation respects actual
+host epoch rather than PID equality and preserves an already confirmed nested release.
+Tests inject manager observations; they do not claim a real systemd restart acceptance.

 Native resource release now requires a matching projectNativeWorkers native-agent-quiescent record, generation/Session/lease scope and absent old Bot. Missing Bot records or undefined handles with exited=true cannot free capacity. The existing native-turn delegation path still requires its actual nonempty matching handle. Actual stopping uses the original SessionController-resolved Agent and awaits whenIdle; unknown prior-host execution remains held for explicit reconciliation.
+
+
+#2184 separates physical release from context recovery. Native normal release needs v2 registered-work quiescence; supervisor release additionally verifies the exact process-group/invocation through the existing manager proof service. A legacy missing carrier can free capacity after actual manager verification without manufacturing native context. Reconciliation preserves a nested confirmed release and uses native host-epoch ownership rather than PID equality to recognize current controllers. No missing PID or timeout is a release proof.

+Seen 1× (native pre-step and existing scheduler regressions). Admission-time rights do not cover role/resource revocation during a long execution. Reuse one live authority check and the existing pool stop/acknowledgement contract. Keep frozen persona/model for continuation, permit only the retained active retired-role claim, and do not await an Agent's idle inside its own pre-step hook. A resumed physical Session also exists in history: select its current live carrier for authorization. Recheck the actual human sender after awaiting the initiating authority.

+## In-flight authority (#2184)
+
+Native bind/activate and canonical SDK start/input use the same current execution-authority check: exact Task/Attempt/claim/generation, current initiating human/delegation, committed role catalog and actual Resource binding. Frozen persona/Skills/model stay frozen; current capability/Harness/resource revocations limit that context. A removed role may finish only its exact retained active claim under archived conventions; it cannot acquire fresh work or borrow another retired identity. An implicit native host cannot bypass a newly explicit resource pool.
+
+The existing serialized scheduler checks ongoing canonical role Sessions before resource reconciliation and new dispatch; no new timer is installed. Native pre-step also checks current authority for the bound Agent/child lineage and asynchronously requests the existing pool stop so it never waits for its own idle inside pre-step. SDK safe next-turn feedback and human input/permission responses revalidate before writing frames. Already running SDK operations stop cooperatively via the existing acknowledgement + process-exit contract; this does not assert retroactive prevention of an external operation already executed.
+
+`projectPools.revokeExecution` is a private host seam, not a new public task endpoint. It fences the exact claim, persists a blocked reason, then invokes the same lifecycle release used for member revocation. Unknown exit keeps occupancy and prevents reassignment; a late result cannot move a revoked claim. Chief's configured inspection can observe and route the blocked Task after existing exit/authority gates; this path does not impersonate a human or automatically close a Task. Tests cover native step, existing scheduler wiring, stale claim, current catalog, prepared and live real SDK subprocesses using an explicit deterministic worker fixture. They do not imply a new real-provider workflow acceptance.
+
+When a physical native Session is resumed under a fresh carrier, ongoing checks select only the current host/live bound record, never an earlier historical binding for that same Session ID. SDK human input checks both initiating authority and the sending actor again after any awaited validation. These two boundaries have failure regressions; the actual DSH return probe reproduced the former and passes after correction.
+
+Current operator disabling of a Resource or removal of its Harness support also requests the same confirmed stop; it cannot be bypassed by a retained role grant. Live deterministic SDK subprocess regression covers both role-pool removal and operator disable.

 #2184 separates physical release from context recovery. Native normal release needs v2 registered-work quiescence; supervisor release additionally verifies the exact process-group/invocation through the existing manager proof service. A legacy missing carrier can free capacity after actual manager verification without manufacturing native context. Reconciliation preserves a nested confirmed release and uses native host-epoch ownership rather than PID equality to recognize current controllers. No missing PID or timeout is a release proof.

 ### 2026-11-03 — New execution adapters need committed read-model coverage
 
 Seen 1× (native projection regressions). A correct native stop/binding is insufficient if queries/events still report only SDK workers.

Keep private personal proposals separate from public governance proposals.

A later Task command persisted it and emitted an unrelated Project change. Return deterministic legacy defaults without mutation and use committed raw catalogs for metadata; keep materialization in explicit writes.

-### Collaboration repairs — 2026-11-01
-
-The owner authorized sequential issues [#34–#41](https://github.com/zy95-12/FlyBot/issues/33), one PR each; see [decision](decisions/2026-11-01-collaboration-repair.md). The target is native multi-Bot reuse, per-Bot pools and enforced handoff, restored role contracts, ordinary Chief conversations, safe/watch delegation and configurable Chief inspection schedules. Public hosting is deferred; control-plane stays unchanged.
-
-R1 (#34) rejects incomplete repository capabilities before workers/workspaces/leases are allocated. Workbench readiness checks Git/runtime/dependency metadata and reports the precise block; this does not claim tests or SDK task delivery have run. Old failed Attempts remain readable. R1 full local verification passed in PR #42; actual shared-service integration remains pending.
-
-R2 (#35) restores complete Dev/Tester/Reviewer conventions, pinned policy-source hashes and final-execution prompt assembly for native and SDK roles. FlyBot code sealing requires memory/tests/architecture evidence; candidate approval explicitly cannot mint a signed forge PASS. Focused tests cover full rules reaching SDK input, required-source failures and tampering. R2 full verification and later backend/dogfood acceptance are tracked separately.
-
-
-R3 (#36) implements per-logical-Bot pools on existing Task records, atomic claims,
-versioned receipts and enforced handoff admission. New shared deliveries default
-to dynamic pool dispatch; the legacy DAG is explicit opt-in. Only the receiving
-role allocates an execution Session/resource. Candidate returns retain the Task
-and create a new Attempt; overall completion waits for Chief judgement. Unit and
-SDK contract-process tests cover non-DAG return/rework with one resource. Full
-verification, conversation bridging, Chief arbitration/schedules and real shared
-service dogfood remain separately tracked acceptance, not implied by these tests.
-
-
-R4 (#37) adds conversation-only private → Chief → original-chat handoff, isolated
-from private memory and other members. Query turns cannot publish or execute a
-Task; scoped GitHub reads provide actual repository facts. Impactful Task kinds
-persist across proposal publication; workbench status separates publication from
-queue/start/execution and Chief wait. Targeted privacy, native/SDK-query, no-Task
-and credential/revocation tests pass. Full verification and real shared-service
-acceptance remain separate; control-plane and public hosting are unchanged.
-
-
-R5 (#38) implements safe/private publication proposals and persistent, revocable
-watch grants bound to the current human and Project. Browser logout does not
-revoke watch authority; account/membership/grant changes do. Scoped actions use
-current human rights and retain provenance. The unchanged SQLite platform can
-supply fresh account status through a FlyBot-owned read-only operator helper,
-without storing browser cookies or admin credentials. Regression tests cover
-logout, restart, current rights, revocation, forged status evidence and fresh WAL
-reads. Shared-service provisioning and real-model acceptance are still pending.
-
-R6 (#39) adds evidence-gated Chief arbitration, audited intervention and configurable
-inspection on original DSH scheduled tasks. The JSON template defaults to 30 minutes;
-content, cadence, thresholds and pause/enable are editable. Current configured human
-authority and generation fences apply to each effect. Unknown process exits retain
-capacity; a verified systemd invocation boundary permits local restart recovery.
-Deterministic protocol tests return incomplete coverage to Dev then close the same
-Task after a fresh Attempt. Real shared-service Codex/timer acceptance remains #41.
-
-Real shared-service R6 probes passed an actual Codex Chief ordinary inquiry with
-zero Tasks and an original DSH 60-second wake after browser logout, then pause/
-resume and restoration to 30 minutes. R7 actual Dev requested Chief arbitration;
-Chief returned the same Task to Dev with a fresh Attempt. This exposed a concurrent
-resource-release reconciliation race, fixed with a red/green regression. Actual
-full R7 delivery and persistent 30-minute/restart acceptance remain in progress.
+### Collaboration contract and earlier validation
+
+Native multi-Bot UI, per-Bot handoff pools and complete pinned role conventions remain required. Ordinary Chief questions are conversations; safe/watch delegation uses current human permissions. Chief inspection uses the original DSH scheduled-task service with editable cadence/content/thresholds (the current template defaults to30 minutes), never a hardcoded framework workflow. Code changes retain required memory/tests/architecture evidence. Earlier R1–R7 implementation and runtime validation are [preserved verbatim](docs/history/2026-11-03-collaboration-repair-evidence.md). Current acceptance follows the convergence records above; no new deployment, Control Plane change or interruption of healthy frontend work is authorized.

+# Earlier collaboration implementation and validation
+
+Preserved verbatim from PROJECT.md; active rules and current acceptance remain in active memory.
+
+### Collaboration repairs — 2026-11-01
+
+The owner authorized sequential issues [#34–#41](https://github.com/zy95-12/FlyBot/issues/33), one PR each; see [decision](decisions/2026-11-01-collaboration-repair.md). The target is native multi-Bot reuse, per-Bot pools and enforced handoff, restored role contracts, ordinary Chief conversations, safe/watch delegation and configurable Chief inspection schedules. Public hosting is deferred; control-plane stays unchanged.
+
+R1 (#34) rejects incomplete repository capabilities before workers/workspaces/leases are allocated. Workbench readiness checks Git/runtime/dependency metadata and reports the precise block; this does not claim tests or SDK task delivery have run. Old failed Attempts remain readable. R1 full local verification passed in PR #42; actual shared-service integration remains pending.
+
+R2 (#35) restores complete Dev/Tester/Reviewer conventions, pinned policy-source hashes and final-execution prompt assembly for native and SDK roles. FlyBot code sealing requires memory/tests/architecture evidence; candidate approval explicitly cannot mint a signed forge PASS. Focused tests cover full rules reaching SDK input, required-source failures and tampering. R2 full verification and later backend/dogfood acceptance are tracked separately.
+
+
+R3 (#36) implements per-logical-Bot pools on existing Task records, atomic claims,
+versioned receipts and enforced handoff admission. New shared deliveries default
+to dynamic pool dispatch; the legacy DAG is explicit opt-in. Only the receiving
+role allocates an execution Session/resource. Candidate returns retain the Task
+and create a new Attempt; overall completion waits for Chief judgement. Unit and
+SDK contract-process tests cover non-DAG return/rework with one resource. Full
+verification, conversation bridging, Chief arbitration/schedules and real shared
+service dogfood remain separately tracked acceptance, not implied by these tests.
+
+
+R4 (#37) adds conversation-only private → Chief → original-chat handoff, isolated
+from private memory and other members. Query turns cannot publish or execute a
+Task; scoped GitHub reads provide actual repository facts. Impactful Task kinds
+persist across proposal publication; workbench status separates publication from
+queue/start/execution and Chief wait. Targeted privacy, native/SDK-query, no-Task
+and credential/revocation tests pass. Full verification and real shared-service
+acceptance remain separate; control-plane and public hosting are unchanged.
+
+
+R5 (#38) implements safe/private publication proposals and persistent, revocable
+watch grants bound to the current human and Project. Browser logout does not
+revoke watch authority; account/membership/grant changes do. Scoped actions use
+current human rights and retain provenance. The unchanged SQLite platform can
+supply fresh account status through a FlyBot-owned read-only operator helper,
+without storing browser cookies or admin credentials. Regression tests cover
+logout, restart, current rights, revocation, forged status evidence and fresh WAL
+reads. Shared-service provisioning and real-model acceptance are still pending.
+
+R6 (#39) adds evidence-gated Chief arbitration, audited intervention and configurable
+inspection on original DSH scheduled tasks. The JSON template defaults to 30 minutes;
+content, cadence, thresholds and pause/enable are editable. Current configured human
+authority and generation fences apply to each effect. Unknown process exits retain
+capacity; a verified systemd invocation boundary permits local restart recovery.
+Deterministic protocol tests return incomplete coverage to Dev then close the same
+Task after a fresh Attempt. Real shared-service Codex/timer acceptance remains #41.
+
+Real shared-service R6 probes passed an actual Codex Chief ordinary inquiry with
+zero Tasks and an original DSH 60-second wake after browser logout, then pause/
+resume and restoration to 30 minutes. R7 actual Dev requested Chief arbitration;
+Chief returned the same Task to Dev with a fresh Attempt. This exposed a concurrent
+resource-release reconciliation race, fixed with a red/green regression. Actual
+full R7 delivery and persistent 30-minute/restart acceptance remain in progress.
+
+End of preserved earlier narrative. Current governing boundaries remain in PROJECT.md.

@@ -210,3 +210,5 @@ Task views distinguish current `roleDefinitionRevision` from pinned `execution.d
 Attempt lists retain at most32 role Session slots and three historical Sessions with bounded metadata/source references. Frozen definitions/Skills and exact context stay available through hash-paged `attempt.context`; they are not copied into every list result. Historical definition references point to `roleSessionHistory`, not the current slot.
 
 Committed Project events include role catalog revisions, public role-governance proposal statuses and native execution activation/exit facts. Private personal-agent proposals/conversations remain excluded. `project.snapshot` retains its default Task page; callers may select `payload.entityType` as `task`, `attempt`, `execution`, `resource`, `input` or `role-proposal` to rebuild other public read-model pages. Non-Task pages return `entities`; all types share the Project revision/event cursor and existing1–100 limit. Continuing pages requires the same `expectedRevision`; unknown/private entity types are rejected. After expiry fetch fresh snapshot pages and resume from that Project cursor. Receiving any snapshot/event grants no execution or approval authority.
+
+Legacy Projects with an implicit built-in catalog report its effective revision1 without materializing it on read. Queries use the raw committed governance catalog, not full Skill/memory execution-context resolution. Explicit configuration/proposals persist through the existing write path. A Project/role read must not create an otherwise unrelated Project change event on the next command.
