Problem
Issue #963 cannot complete its multi-instance fleet-readiness gate because the sanctioned controller/reconciler interface cannot enumerate the live fleet at application instance granularity. Grouping by profile or
client_typealone incorrectly treats legitimate concurrent clients (for example two independent Codex launches) as duplicate MCP processes.Implementation summary
mcp_fleet_snapshot.py— pure assessor: trusted instance identity helpers, point-in-time snapshot, full classification set, heartbeat continuity comparison.gitea_snapshot_instance_fleet— read-only MCP tool on controller and reconciler only (gitea.read; no new mutation permissions).mcp_worker_identity.WorkerRegistry— optional columns (fleet_run_id, revisions, process identity, provenance); refuse a second live worker for the same(client_instance_id, namespace).GITEA_MCP_CLIENT_INSTANCEis trusted; missing key uses an explicit legacy placeholder (not silent multi-instance collapse); namespace + revisions recorded when available.docs/instance-fleet-identity.md(identity hierarchy, lifecycle, manifest, fail-closed recovery); tool inventory entry.tests/test_issue_978_instance_fleet_snapshot.py(35 cases covering ACs).Identity lifecycle design
client_typeGITEA_MCP_CLIENTclient_instance_idGITEA_MCP_CLIENT_INSTANCE)fleet_run_idGITEA_MCP_FLEET_RUN_IDworker_identitynamespaceAll five namespace workers of one launch share one
client_instance_id. Multiple instances of the sameclient_typeare first-class.Snapshot and consistency semantics
Each snapshot returns
snapshot_at,consistency_token/registry_revision(content digest), live/historical/stale worker rows, instance groupings, findings,live_fleet_safe, andmutation_safe. Registry is the sole production authority (no process-table/SQLite inspection as evidence).Duplicate / conflict classification
Not duplicates: shared profile or
client_typealone.Active blockers: instance-ID collision; duplicate namespace within one instance; reused worker/session/generation/process/PID/fencing identity; missing expected / unmanifested instance; unknown client; foreign repository; old revision; stale worker; legacy incomplete identity; orphaned workers.
Historical dead rows: reported separately with
active_blocker=falseand never make the live fleet unsafe by themselves.Same-type multi-instance proof
Regression test registers two Codex instances × five namespaces (ten workers), asserts correct attribution,
multi_instance_same_client_type, andlive_fleet_safewith no same-type-as-duplicate finding.Permission changes
snapshot_instance_fleet/gitea_snapshot_instance_fleet→gitea.read, rolecontroller.role_kindtocontroller|reconciler.GITEA_MCP_FLEET_RUN_ID,GITEA_MCP_PROCESS_IDENTITY.Migration / legacy behavior
Existing single-client fleets continue to work. Registrations without a trusted launcher instance ID are classified as
legacy_incomplete_identity(diagnostic reads OK; fleet mutation_safe false). Optional registry columns migrate viaALTER TABLEwithout rewriting history. Historical released/superseded rows retained.Tests run
Security / credential isolation
Role endpoints still load only their profile credentials. Snapshot is observational only. No tokens, secret material, or foreign credentials in responses. Registry public records exclude token fingerprints.

NEXT_ACTION: Remediate the two blockers below on branch feat/issue-978-instance-fleet-snapshot, push, and request re-review; this REQUEST_CHANGES supersedes the mistaken APPROVED review 654 at the same head under an operator-authorized scoped correction (#693).
NEXT_PROMPT:
WHAT_HAPPENED: Independent reviewer re-verified PR #979 at head
4a1cc63e94. The snapshot assessor, registry columns, classification set and the 35-case focused suite are sound and were re-confirmed, but two blockers were established after review 654 was submitted and were not covered by it. Review 654 was therefore mistaken; an operator-authorized scoped correction (#693, same PR and same head only) was recorded and this single REQUEST_CHANGES verdict supersedes it. No merge was performed, no code was modified, and no issue state or label was changed.WHY: PR #979 claims instance-level fleet readiness for #963, but the trusted-identity path it depends on is never produced by any production launcher, and the gate that actually decides whether a mutation may proceed is still keyed on profile rather than application instance. Both defects sit precisely on the acceptance criteria that #963 needs, so the PR cannot land as an unblocking change until they are fixed.

NATIVE_REVIEW_PROOF: transport=native_mcp; entrypoint=gitea-reviewer; profile=prgs-reviewer; identity=sysadmin
BLOCKERS: B1 — no production launcher generates and propagates one shared, trusted client_instance_id to all five namespace workers, so every real launch lands as legacy placeholder identity and the trusted multi-instance attribution the PR is built on is unreachable outside tests; unblock by having the launcher mint one instance ID per application launch and pass it to all five workers on the real serve path, proven by five registrations sharing one client_instance_id with no legacy placeholder. B2 — the real mutation-capability gate remains profile-based, so two concurrent valid LLM application instances are still classified as duplicate MCP processes and every mutating task fails closed with runtime_reconnect_required; unblock by making that gate instance-aware, proven by a mutating capability resolve succeeding while a second legitimate instance is live, without weakening duplicate detection for the same (client_instance_id, namespace).

0dbff6dcd5(delta from prior reviewed head4a1cc63e94). Both blockers from review 655 are satisfied. Formal APPROVE submitted; supersedes stale REQUEST_CHANGES 655 which targeted the prior head.WHY: Production launcher path now mints and propagates one trusted client_instance_id per application launch to all five namespace workers, and the real mutation-capability runtime diagnostic is instance-aware so two legitimate application instances may share a profile without false duplicate classification, while same-(instance, profile/namespace) collisions and missing trusted evidence still fail closed.
