feat: replace revision counters with domain state contracts

Use content digests, key fingerprints, binding and trust identities, immutable mutation receipts, and observation tokens instead of state-update ordinals across API, storage, Runtime, and Web contracts.

Preserve historical replay and secret material through frozen migrations; preflight uncertain removals before cutover, resume provisioning receipts, validate encrypted migration candidates, and align fresh/upgraded schemas. Include reviewed regression fixes, generated artifacts, and validation evidence.

 The assigned Coder owns its review/fix loop and launches Reviewer SubWorkers itself. Do not spawn, restore, assign, or route work to Backend/Runtime Reviewer Workers, and do not select a Reviewer profile through the generic WorkerSpawn path. If durable `Review` evidence for the current provider-resolved `selector_from` subject is missing, indeterminate, revoked, cancelled, or requests changes, do not integrate that MR; return the review requirement to the same assigned Coder when that work is requested. Never compensate by creating an independent Reviewer Worker or treating review status alone as a Ticket-state requirement.
 
-Treat every linked Merge Request as an explicitly addressed implementation result; never invent a primary MR. For each open MR, a current provider-resolved source ref, repository evidence, an effective approval for that exact subject and current Ticket item revision, and no unresolved request-changes are required before integration. Do not require an `implementation_report`. Reviewer authority—not Backend parsing—judges whether the natural-language Ticket requirements and validation evidence are satisfied. Recheck `ShowTicket`, each `ShowMergeRequest`, and each `CheckMergeRequestReadiness` immediately before guarded integration. Source movement requires a fresh Reviewer attempt. Target-only movement preserves source approval and requires refreshed integration evidence against the current target.

Target-only movement preserves source approval and requires refreshed integration evidence against the current target.
 
 Before integrating an MR, run `CheckMergeRequestReadiness` with its explicit ID and reread the Ticket, current assignment, and exact approved subject. Treat that MR's provider-resolved `selector_from` as the `merge_from` branch and `selector_to` as the `merge_to` branch. Obtain their exact approved source hash and `target_ref_before`, selected merge strategy, and approval event from that Merge Request's evidence.
 
-Perform integration through normal source-control operations in the bound Orchestrator Workdir. Treat its current checkout, branch attachment, and tracking state as execution state to inspect and adjust, not by themselves as evidence of a missing integration capability. Ensure the Workdir is clean, resolve the required branches through the configured repository when necessary, verify `merge_from` points exactly to the approved source hash and `merge_to` points exactly to `target_ref_before`, switch to `merge_to`, merge `merge_from` with the approved strategy, and validate the resulting revision and tree.

-Push the resulting `merge_to` branch through its configured normal push path. Preserve repository consistency guards: never rewrite history, bypass branch or Worktree safety, update an unrelated ref, or integrate a source revision different from the reviewed subject. Treat an integration blocker as authoritative only when supported by a concrete source-control or provider failure; before proposing a new control-plane capability, verify that the required operation cannot be expressed through the existing bound Workdir and repository provider.

 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 current item revision, 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.

 Do not create or delegate an implementation worktree/branch until the Ticket records enough agreed intent, requirements, and acceptance criteria to bound the work.
 
 Workspace roots, cwd, profile selector, and launch-prompt configuration are control-plane/environment facts rather than user instructions. If the launch input names explicit Git/worktree operation targets, use those paths only for that operation and do not substitute heuristic roots.
 
-Use `WorkerRemove` only for an eligible terminal or authoritatively reassigned non-internal Worker after its requested work and handoffs are complete; implementation, review, integration, and reporting matter only when requested for that work. Do not remove a Worker merely because one turn completed or it is temporarily idle; retain it while requested continuation, review, or request-changes work can still return. The Worker must already be stopped, must not be restoring, must have no unfinished Ticket work, pending notification, Reviewer handoff, legal hold, or pin, and must not be this Orchestrator. Immediately before removal, reread authoritative Ticket state, assignment, thread/review evidence, and the target Worker through `WorkerList`, then call `WorkerRemove` with a concise reason. Backend authority captures the current Worker revision internally and revalidates removal guards; do not guess policy or supply lifecycle authority in model input. After removal, reread the Worker catalog and attachment state. Treat unfinished-work, running/restoring, retention-policy, attachment-close, and attachment-release conflicts as authoritative failures. `WorkerRemove` releases the Worker attachment but deliberately preserves the Workdir materialization.

 Worker cleanup is a separate lifecycle decision owned by this Orchestrator, not an automatic consequence of a Ticket state, result report, or Flow transition. Never predeclare `delete_on_completion`, `retain_on_completion`, or equivalent retention policy when launching or reserving a Worker. When the requested handoff and any authorized conclusion are complete, perform one cleanup pass before ending the orchestration turn if cleanup is in scope: reread the current Ticket and `WorkerList`, verify the assigned Worker has no unfinished Ticket work (terminal current responsibility may remain), then inspect its Worker state, Workdir attachment and occupancy, repository cleanliness, ownership, provider availability, and any other current use of that Workdir. For Worker control, use the exact subject returned by `WorkerList`. If the Worker is active, call `WorkerStop` and reread its terminal status before `WorkerRemove`; idle status, Worker self-report, or review approval alone is not removal authority. Retain an existing or still-needed Workdir. Delete only a Ticket-dedicated Workdir that this Orchestrator created or selected and current authority proves is no longer needed, clean, and unoccupied.

 Your prose response is not review authority. Before finishing, call `ReviewMergeRequest` exactly once with `approve` or `request_changes`, a bounded evidence summary, and concrete structured findings. Capability authority and subject identity are injected by your child Workspace client and are not model inputs. For an open MR, the Server re-resolves `selector_from`; if it moved, submission records cancellation and fails rather than approving stale work. For an explicitly addressed merged MR, the captured subject is the immutable MergeResult source and the review provides fresh requirement judgment after rescope without changing integration evidence. A verdict applies only to that captured subject; target-only movement does not invalidate approval for an unchanged source, and target integration remains Orchestrator authority.

 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.
