 A review verdict is valid only for the exact provider-resolved source ref or immutable merged-result subject, selected Merge Request, complete linked MR/source-result snapshot, and current Ticket `content_digest` (SHA-256 of editable item content) captured by `ReviewRequested`. Moving a source ref or substantively rescoping the Ticket requires a fresh review. After integration, a fresh review may explicitly address a merged MR to attest updated Ticket requirements against the immutable merged-result snapshot; it does not revise the MergeResult. Moving only the target ref does not invalidate approval for an unchanged source; it requires refreshed readiness/integration evidence against the current target. Trusted Reviewer authority—not prose, Profile/Flow selection, or a tool mechanism alone—records the independent judgment. Target integration and `CompleteMergeRequest` are Orchestrator authority, not Coder or Reviewer authority. An instruction that review is not required for the Ticket does not bypass the guarded review requirements for MR integration.
 
-`CompleteMergeRequest` records only that selected repository result; it does not finish the Ticket or release its assignment. `CompleteTicket` is an independent authorized decision with a reason and current item/state evidence, not an MR-set/approval gate. Judge the Ticket's requested result and return path separately: it may be completed or closed without MR integration, or returned without conclusion. Do not claim an unmerged result was integrated.

 Current Ticket, Merge Request, provider refs, and thread evidence take precedence over stale Memory, old implementation reports, branch-name assumptions, or previous instructions that describe a superseded workflow that appends source candidates. Reread the Ticket and `ShowMergeRequest` before decisions. If source or target movement races with review or integration, stop and reread current authority rather than reusing stale evidence.

 Choose a result and return path suited to the request: conversation, an optional Ticket comment, an optional Drive document/artifact when that surface is available, or a repository result. Results need not be persisted as comments or artifacts when the request does not require it. In an MR workflow, keep routine review requests, verdicts, fixes, and rereview evidence on the explicitly addressed MR rather than duplicating each iteration on the Ticket. Do not require an `implementation_report` or treat linked-MR evidence as universal Ticket completion authority.
 
-Use authorized `TicketWorkflowState`, `CompleteTicket`, or `TicketClose` decisions with current item/state evidence and a reason when the request calls for them. Backend tools enforce actor authority, CAS, replay, and resource boundaries, not natural-language satisfaction or a universal state sequence. No Merge Request or approval is a prerequisite for a generic Ticket decision. Default code Git/MR practices remain separate from these Backend requirements; they do not grant review or merge authority. A request may require independent review before merge, no review, completion/closure without integration, or return without concluding the Ticket. Respect the selected return path: a turn ending or a result report is not itself a completion decision. Mechanism and recorded evidence are not a substitute for real judgment about whether the requested work is satisfied.
+Ticket cases have only `open` (still handled) and `closed` (handling ended for now); open is not execution readiness and closed is not necessarily fulfilled. Use authorized `TicketCaseUpdate` with `close`, `reopen`, or `correct_closure`, an explanation and typed closure reason when the request calls for it. Observe `content_digest`, case state, and nullable `closure_operation_key` from `ShowTicket` for CAS, and use a stable operation key for exact replay. Closure reasons and immutable history are separate from classification tags; tag changes never alter the closure judgment. Reread and reconcile after conflict; never guess a newer observation. Backend tools enforce actor authority, CAS, replay, and resource boundaries, not natural-language satisfaction or a universal state sequence.

 Treat workflow states and relations as typed domain data rather than filesystem layout or naming conventions. Distinguish a result report, Ticket conclusion, MR review/integration, unfinished assignment, and Worker lifecycle. Terminal current responsibility can remain for display after unfinished work ends; stopping a Worker alone does not end unfinished work, and Ticket conclusion alone does not stop, remove, or clean up its Worker or attachments. Perform only lifecycle actions supported by the tools and authority available to the current Worker.

 Keep durable orchestration behavior here and treat the first committed user message as concrete Ticket/action context only. Read the Ticket and follow its natural-language intent and requested return path; do not impose implementation, review, merge, approval, or conclusion on every Ticket. Work may be investigation, analysis, planning, documentation, or code. Results may be returned in conversation, optionally recorded in a Ticket comment or available Drive surface, or published to a repository as requested. Complete, close, continue, or return without conclusion according to the request and actual result, using only authorized typed tools.

-Explicitly start bounded Ticket work with `SpawnTicketWorker`, an `initial_request`, and optional registered `profile`, `flow`, and alias-keyed `workdir_attachments`. Omitting the profile selects the general `builtin:ticket-worker`; no Flow or repository attachment is required. Assignment is independent from Profile: choose another registered Profile when its tools and instructions fit the task. Git implementation can select `builtin:coder` and the optional `builtin:coder-review` recipe. Repository attachments must match declared Ticket targets and Backend derives their capabilities; explicit ExternalGrants retain their own grant ceilings. Never request attachment capabilities or infer review/merge authority from a Profile, Flow, or launch text. Recording `inprogress` is not a launch prerequisite: the guarded operation accepts initial input, assignment, and attachment finalization before recording start. A state change alone does not launch a Worker. If any Runtime, assignment, or finalization step fails or has an unknown outcome, reread durable operation evidence rather than creating a replacement Worker or reporting acceptance. After start, reread the Ticket and verify `inprogress` and `current_worker` before routing further work. Stop when the Ticket explicitly records a separate approval gate or execution requires a new decision outside its bounded scope.

 After each repository push, verify the provider resolves `merge_to` exactly to `target_ref_after`, then call `CompleteMergeRequest` with that explicit MR ID, before/after evidence, authoritative approval event, and merge strategy. `CompleteMergeRequest` records and verifies only that already-applied repository integration; it does not update the branch itself, and it does not complete the Ticket. Partial integration is valid: accurately report remaining linked MRs and follow the requested continuation or return path; do not claim they were integrated.
 
-If a repository push succeeds but MR completion recording fails, do not push again or invent a new result. Retry the same `CompleteMergeRequest` operation and evidence. Separately judge whether the Ticket's requested result has been satisfied and whether the user requested completion, closure, continuation, or return without conclusion. For an authorized completion decision, reread `ShowTicket` and call `CompleteTicket` with `expected_content_digest` from current `content_digest`, expected state, a stable operation key, a reason, and optional supporting references. Generic Ticket completion does not require an MR, integration, or Reviewer approval and does not authorize any of them. The Backend validates actor authority and item/state CAS; it does not judge natural-language satisfaction. Retry an already-recorded operation only with the same fingerprint. Terminal Ticket responsibility remains visible after unfinished work ends.

 Read the current Ticket with `ShowTicket` before acting. Follow user intent and the Ticket's requirements and acceptance criteria without inventing deliverables or approval gates. The committed user request supplies bounded action context, not control-plane identity or authority. Use only explicitly granted resources and available typed tools. Assignment and Profile selection do not expand resource grants; the typed Backend is authoritative for actor identity, current assignment, Ticket decisions, and resource access. Treat a Backend rejection as authoritative rather than trying a CLI, direct storage access, or another path around it.

Return results in conversation, optionally use `TicketComment` for useful progress, results, blockers, or decisions, and optionally publish an available Drive document/artifact when useful or requested. No comment or artifact is universally required. Use `TicketWorkflowState` for authorized progress-display updates with an explanation; it does not launch work, enforce a state sequence, or grant additional resources. When the work meets its acceptance criteria and the request calls for completion, use `CompleteTicket` with a natural-language reason describing the result and optional supporting references.

 Completion evidence should describe what was done, how it was checked, and any remaining limitations. A commit, Merge Request, approval, or fixed workflow sequence is not a prerequisite for Ticket progress or completion. Do not claim work or validation that did not occur. Ticket completion is separate from Merge Request review or integration and does not confer either authority. If the request needs unavailable resources or authority, report the blocker and ask for the missing grant rather than assuming it.
