Merge pull request 'ci: fix publish Docker healthcheck pipefail' (#952) from fix/publish-healthcheck-pipefail into main

mc#948 (BP→emitter drift): `sop-checklist / all-items-acked
(pull_request)` was required by branch protection but the workflow
was named `sop-checklist-gate`, so it emitted the misnamed context
`sop-checklist-gate / gate (pull_request)` instead.

Rename to align the workflow's `name:` field with the context that
BP requires:
  sop-checklist-gate.yml → sop-checklist.yml
  sop-checklist-gate.py  → sop-checklist.py
  test_sop_checklist_gate.py → test_sop_checklist.py

New context emitted: `sop-checklist / all-items-acked (pull_request)`.

Added `# bp-required: yes` directive to the workflow header per
Tier 2g lint convention (mc#774).

All 52 script tests pass.

Closes #948.

+"""Test coverage for builtin_tools.security._redact_secrets().
+
+Issue #834 (C2): commit_memory must not persist API keys verbatim.
+
+Pre-commit hook blocks bare secret-like strings (ghp_, sk-ant-, etc.) to prevent
+accidental commits of real credentials.  These tests focus on the functional
+behaviour of the redaction logic: idempotency, contextual keyword=value patterns,
+boundary cases, and mixed content — without triggering the hook's length thresholds.
+The pre-commit hook itself is the primary guard for bare-pattern detection.
