Why: Multiple branches were repeatedly syncing a moving main, resolving the same conflicts, and rerunning final CI before they were actually next to merge.
Evidence: At dfd608b1cf9101999a075e88f2dccc6862fa2a03, make test and make build passed from source-out SELF receipts. Scope, relative-link, diff, and recursive worktree checks passed. Independent Review found no remaining findings after correcting one stale anchor, the final-window conflict owner, and the evidence wording. The PR HEAD still requires the platform's test, test-pg, and svc-realcombo checks.
Impact: Waiting branches keep developing without chasing main. One task at a time gets the final window to sync once, resolve conflicts, run exact-head checks and Review, and be merged by the agent. Card-close PRs use the same queue. This change does not add writer audits, a second trial, platform or runner changes, automatic locking, fencing, or business-task takeover. No additional operational monitoring is required because this changes delivery documentation only.

Refs: Agent-System-Dev #518
Why: establish the authorized task workspace and its initial baseline.
Evidence: preserved precheck receipt in .task/feature-merge-queue-simple-policy.md; R0=33261925a10c4eee40d1b6175b3895e78a47ef02.
Impact: task metadata only; the feature workspace starts at 33261925a1.
Refs: .task/feature-merge-queue-simple-policy.md
Why: Keep branches developing independently and serialize only final sync, validation, and agent merge without expanding into audits or new platform mechanisms.
Evidence: scope and link checks, git diff --check, and recursive worktree verification passed as SELF evidence in the task card.
Impact: Documentation only; existing task-sync, CI, branch protection, and agent merge behavior remain unchanged.
Refs: Agent-System-Dev #518
Why: Freeze the queue attempt and exact base before final validation.
Evidence: task-sync returned changed=0 on base 33261925; Issue #518 comment 6408 records the window.
Impact: Task record only; policy content is unchanged.
Refs: Agent-System-Dev #518
Why: Keep final sync and conflict handling with the merge agent and avoid treating pre-freeze SELF checks as final evidence.
Evidence: Review found one stale anchor, one ownership ambiguity, and one evidence-scope overclaim; all three are corrected.
Impact: Documentation only; no runtime or platform behavior changes.
Refs: Agent-System-Dev #518
Why: include the current integration baseline before verification.
Evidence: fetched origin/main=b8edf13dc7b818d6e61b829f6e88202ec553f2fc.
Impact: integrate upstream changes without rewriting task history.
Refs: task-sync
Why: Preserve the one changed-base sync before freezing the final candidate.
Evidence: task-sync merged main b8edf13 without conflicts and reported tested checkpoint 4272d55.
Impact: Task record only; policy content and runtime behavior are unchanged.
