Why: establish the authorized task workspace and its initial baseline.
Evidence: preserved precheck receipt in .task/feature-rdm-two-trees-followup-w3-rest.md; R0=2b7fdc39a1f44163f4766701429d61ffd6926f1a.
Impact: task metadata only; the feature workspace starts at 9e6d9690f6.
Refs: .task/feature-rdm-two-trees-followup-w3-rest.md
Why: record the authorized end point and scope for the W3 remainder child task.
Evidence: card fields only (SELF).
Impact: task card only.
Refs: docs/superpowers/specs/2026-10-19-rdm-two-trees-followup-a1-review.md
Co-authored-by: Cursor <cursoragent@cursor.com>
Why: W3 remainder is implemented on RDM draft PR #451 and needs the user's stage 6 review before merging into the initiative.
Evidence: RDM f3fa0c0 target tests and domain/rdmapp packages pass locally (SELF); fresh-session review PASS-with-fixes with no blocking findings.
Impact: task cards and review docs only; placement checks recorded as a W4 write-entry prerequisite.
Refs: feature/rdm-two-trees-followup-w3-rest, RDM PR #451
Co-authored-by: Cursor <cursoragent@cursor.com>
Why: the task card and PR description are one document and must point at each other.
Evidence: PR #641 opened against feature/rdm-two-trees-followup.
Impact: task card only.
Refs: PR #641
Co-authored-by: Cursor <cursoragent@cursor.com>
Why: The user approved the W3 remainder at stage 6 on 2026-10-20 and authorized merging RDM #451 into RDM main.
Evidence: RDM #451 merged at 76b4c05 after head f3fa0c0 status success; merged tree 4cfacf16 matches the pre-merge merge-tree.
Impact: Task cards and review package only; W4 write entry points must first add node placement checks.

Why: close the task card inside its own PR so landing it needs no post-merge backfill or separate close PR.
Evidence: .task/feature-rdm-two-trees-followup-w3-rest.md -> .task/archive/feature-rdm-two-trees-followup-w3-rest.md; status 已完成（合入前闭合）; PR #641https://git-home.u1680832.nyat.app:30319/weichen/Agent-System-Dev/pulls/641.
Impact: task metadata only; the card is archived within PR #641 and lands with its merge commit.
Refs: task.sh close --self
