Why: cleanup, component synchronization, receipt recording and credential handling could contradict the documented development boundaries.
Evidence: SELF 75 isolated governance tests and source checks are captured in .task/feature-governance-reliability.md; combination and CI verification follow.
Impact: hardens local task and CI tooling, aligns policy and component documentation, and adds continuous regression tests without changing product behavior.
Refs: .task/feature-governance-reliability.md; policy/governance.md; policy/platform-admission.md
Why: zcode lacks a rules feature (AGENTS.md is the resident layer) but
supports PreToolUse hooks that can block Edit/Write before the write lands,
upgrading A1/A3 from commit-time to write-time enforcement; the two block
shapes (integration branch, detached submodule) mirror the real incidents.
Evidence: script-level suite 8/8 (N1-N3 blocks with exit 2 and remediation
hints, P1-P5 allows incl. fail-open degradation paths); config JSON valid;
client-side live-fire interception marked pending-live in the matrix.
Impact: .zcode/config.json enables the hook runner for this workspace;
.zcode/plans/ ignored (client state); no product code change.
