Why: check-pins requires nested and Dev-level pins to agree; squad main
advanced to 819b0c5 (nested agent-native pin #48) and backend main to
fe7c245 (nested agent-squad pin #103) after the Q3 WP1-WP5 merges.
Evidence: both component PRs CI green (GATE); make test recorded via
make evidence in the follow-up commit on this branch.
Impact: deps/agent-squad 663e89e -> 819b0c5; modules/backend 4791b2e ->
fe7c245; deps/agent-native stays 37c5e6f.
Refs: Q3 plan WP6; task card .task/feature-agent-stack-q3.md
Why: Q3 WP1/WP2 moved workflow execution out of runtime (workflow_script.go
deleted, so runtime no longer imports internal/tools) into the new
internal/wfcompile package, which legitimately depends on internal/tools
(script host) and internal/workflow (render/validate/Launch data layer).
Evidence: make test-boundaries green after the baseline update (77 edges,
negative test ok); the lint itself flagged both the stale edge and the new
ones (SELF).
Impact: baseline -1 edge (backend/runtime backend/tools), +3 edges
(backend/runtime backend/wfcompile, backend/wfcompile backend/tools,
backend/wfcompile backend/workflow).
Refs: Q3 plan WP1/WP2; task card .task/feature-agent-stack-q3.md
Why: Q3 (convergence and interop) completed across agent-native (#40),
agent-squad (#46/#47) and backend (#99-#102); Dev gitlinks must track the
merged component mains and the task card records the outcome before the
completion declaration.
Evidence: card increment table rows WP1a-WP6 with merged PR/SHA references;
component CI statuses recorded as GATE in the card verification section;
three-segment outputs (precheck/task-sync/test) appended via make evidence
in follow-up commits on this branch.
Impact: deps/agent-squad bcc8d08 -> 663e89e, deps/agent-native 1ac21c6 ->
37c5e6f, modules/backend 06934bc -> 4791b2e; task card filled.
Refs: .task/feature-agent-stack-q3.md; Q3 plan 2026-10-07-agent-stack-q2q3-plans.md
Why: establish the authorized task workspace and its initial baseline.
Evidence: preserved precheck receipt in .task/feature-agent-stack-q3.md; R0=78409a9ceacacf8a152b811d94c7195c4f084664.
Impact: task metadata only; the feature workspace starts at 78409a9cea.
