Why: establish the authorized task workspace and its initial baseline.
Evidence: preserved precheck receipt in .task/feature-conversation-handoff.md; R0=f97917032d143188bc7faf665aff612d9814af4e.
Impact: task metadata only; the feature workspace starts at f97917032d.
Refs: .task/feature-conversation-handoff.md
Why: capture the approved scope, acceptance criteria, and verification for the handoff policy change.
Evidence: SELF checks recorded in .task/feature-conversation-handoff.md.
Impact: task metadata only; policy implementation remains in the prior transport commit.
Refs: feature/conversation-handoff
Why: close the task card inside its own PR so landing it needs no post-merge backfill or separate close PR.
Evidence: .task/feature-conversation-handoff.md -> .task/archive/feature-conversation-handoff.md; status 已完成（合入前闭合）; PR #651https://git-home.u1680832.nyat.app:30319/weichen/Agent-System-Dev/pulls/651.
Impact: task metadata only; the card is archived within PR #651 and lands with its merge commit.
Refs: task.sh close --self
Why: keep the archived task record accurate after required CI reported an unrelated backend failure.
Evidence: GATE run #4403 failed test-pg at TestArtifactFacadeCard; svc-realcombo passed.
Impact: task metadata only; PR remains unmerged pending green required CI.
Refs: PR #651
Why: Required Backend CI still blocks PR #651 after the original repair stopped.
Evidence: Preserve the fail-stop receipt and record the read-only reconciliation.
Impact: Restore the active task record; implementation remains delegated.
Refs: PR #651
Why: Continue the authorized CI repair with reconciled task identity.
Evidence: The original LOCAL_READY receipt is imported through make task-resume.
Impact: Task metadata only; final delivery still requires synchronization and CI.
Refs: PR #651
Why: Preserve the verified repair while keeping runtime composition adoption with PR #653.
Evidence: Backend #226 merged after exact-head CI; host receipts imported unchanged.
Impact: Task metadata only; Dev PR #651 still requires its own final CI.
Refs: PR #651; Backend PR #226; PR #653
Why: include the current integration baseline before verification.
Evidence: fetched origin/main=17f8bc06c110014b9101e7a33729d9f5445bd123.
Impact: integrate upstream changes without rewriting task history.
Refs: task-sync
Why: Finish the scoped documentation delivery with the latest authoritative policies.
Evidence: Synchronized target and direct document/config/component checks pass.
Impact: Task record only; exact-head CI remains pending.
Refs: PR #651; queue #518
Why: Retain the strict READY check before freezing the documentation candidate.
Evidence: make evidence captured the complete precheck output with exact source and target.
Impact: Task metadata only; final CI remains required.
Refs: PR #651
Why: close the task card inside its own PR so landing it needs no post-merge backfill or separate close PR.
