 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. Chief role proposals now require separate Maintainer/Owner approval with exact-hash/revision fencing and durable Effects proof; retirement preserves Task/Session and room history. Custom-role physical execution remains #2184 acceptance, and later 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 includes repository relations, Owner closure and Chief-proposed/Owner-or-Maintainer-approved role governance. Execution integration for custom/retired roles remains in #2184; ancestor changes must propagate through the PR stack before final compatibility acceptance.

+# 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.
