Why: establish the authorized task workspace and its initial baseline.
Evidence: preserved precheck receipt in .task/feature-cursor-explicit-model-auto.md; R0=ac594c90e536cfb670e94680f045a6c8247a2513.
Impact: task metadata only; the feature workspace starts at ac594c90e5.

Why: the Dev repin passed a fresh-session review and full CI on 115ca51.

Why: include the current integration baseline before verification.
Evidence: fetched origin/main=162c5a0160955989608f325b4be30458e3717d16.
Impact: integrate upstream changes without rewriting task history.

Why: ci/test was failing on pre-existing TestDSNFileMode in modules/backend pkg/identity. Backend main has progressed past 3f4b34a to b351fd5 (PR #220 fix).
Evidence: Backend origin/main b351fd5 includes PR #220 TestDSNFileMode fix; pre-existing pkg/identity/TestDSNFileMode fails on 3f4b34a in this Dev's environment (umask 0077 prevents the test's expected 0644 file mode).
Refs: PR #220.
Why: U6 (delivery) prepared PR #628 with comprehensive description; CI runs but fails on pins mismatch (Backend 3f4b34a expects agent-intent=651a2e1 etc., Dev pins=343b1e6 etc.) and missing services (test-pg / svc-realcombo).
Evidence: PR #628https://git-home.u1680832.nyat.app:30319/weichen/Agent-System-Dev/pulls/628; CI run #4294 failed on test-pins + test-pg + svc-realcombo; PR base gate passed after archiving 17 child task cards; receipts /tmp/iam-link-u6-pr-gate-20261019.json + /tmp/iam-link-integration-final-20261019.json.
Impact: U6 blocked at CI gate; subsequent session must either bump Dev submodule pins (separate change) or coordinate Backend/RDM/Frontend main merges before L1→main.
Refs: plan revision 3 U6; PR #628.
Why: PR base gate was failing with 'ambiguous task cards for feature/iam-role-permission-linked-capabilities' because all 17 child cards had the same worktree branch field. Archive child cards so only the L1 main card matches the branch.
Evidence: scripts/task_pr_check.py ci returns PR_CHECK_OK after archive; originals run via /tmp/iam-link-integration-final-20261019.json etc.
Impact: PR #628 PR base gate now passes; CI can proceed.
Why: cursor attempt 1+2+3 all returned blocked (Playwright needs running dev backend; vitest-only-only-rejected).
Evidence: receipts /tmp/iam-link-u5-frontend-run.json (latest attempt); U5-Frontend child card.
Impact: U5-Frontend in blocked state; Playwright e2e deferred to a session with dev backend; vitest-only deferred to a session with revised constraints.
Refs: plan revision 3 U5; PR #628.
Why: cursor attempt 1 (run_id=2c62b42a…) + attempt 2 (run_id=f13f176d…) + attempt 3 (run_id=6b1bb5cc…) all returned terminal_status because the agent correctly refused to modify production code (which the unit packet strictly forbade) to add test helpers.
Evidence: receipts /tmp/iam-link-u5-rdm-run.json run_ids 2c62b42a / f13f176d / 6b1bb5cc; U5-RDM child card .task/feature-iam-role-permission-linked-capabilities-u5-rdm-integration-tests.md.
Impact: U5-RDM in blocked state per explicit fail-stop; worktrees show agent did modify allowed test files but couldn't complete without touching production; subsequent session should split U5-RDM further or relax the production-edit constraint.

Why: U5-Backend (first sub-unit of U5) succeeded with cursor-agent attempt 2 (run_id=9af431f5…) terminal_status=success; transport refs/agent-exec/9af431f5…/be45632be6b8 fast-forwarded to feature/iam-link-u1-capability-association @ 1214ad43 on Agent-System-Backend, then pushed.

Impact: U5-Backend complete in Backend (project_iam_integration_test.go with 7+ new IAM chain integration tests); U5-RDM and U5-Frontend sub-units still pending.
Refs: plan revision 3 U5; PR #628.
Why: record authorization, R1 and the stage 4/5 review state for O2.

Impact: U4 implementation complete in Frontend (5-second auto-discovery, capability-group UI replacing checkbox grid, creator/owner/member duties display, empty-list no-create, member-management entry hidden for unauthorized actors); U5 integration-tests is the next step.

Impact: U3 implementation complete in RDM; pins/agent-system-backend bumped to Backend main 3f4b34a; 4 error categorizations (409/403/404/503) integrated; CapabilityExplain consumed from Backend U3A; U4 frontend-auto-discover is the next step in dependency chain.
