Adds metadata blocks (key/status/since/supersedes/superseded-by + Rule/Signals/Mechanics) to all 26 legacy-unmigrated ## records across optimistic-concurrency.md (7, concurrency.*), api-auth-security.md (9, security.*), release-ci-governance.md (7 remaining legacy records, release.*), and spa-modularization.md (3, spa.*). Heading text and rationale prose are byte-identical; only metadata was inserted, per the key-table assignments. security.session-auth-dual-credential (#295 PR1) gets a one-line cross-reference noting it narrows the OIDC-inert sub-claim of security.blazor-removal-auth-posture (#206), per orchestrator adjudication — both stay status: active with supersedes/superseded-by: none.

Active decisions — catalog / task router
The compact current view of settled decisions. Each row is an active record; follow
the link for rationale. Superseded/retired history lives in archive/. Regenerated by
scripts/build_decisions_catalog.py.
| Key | Current rule | Since | Record |
|---|---|---|---|
ci.peak-anon-measurement |
The test job's headline memory figure is a sampled high-water mark of cgroup anon, produced by scripts/ci-peak-anon.sh; memory.peak and the end-of-job anon/file split are kept only as a cache-inflated reference. |

ci.root-screenshot-guard |
The Husky pre-commit hook refuses a staged root-level *.png (belt-and-suspenders with the .gitignore rule); nested *.png real assets are unaffected. |

ci.runner-placement |
No persistent Roslyn compiler server survives a CI build (UseSharedCompilation=false etc., runner env + Dockerfile ENV); every services: container gets its own explicit --memory/--memory-swap/--cpus cap (it does not inherit the job container's). |

docs.decision-lifecycle |
every decision ## record (active or archived) carries a 5-field metadata block (key, status, since, supersedes, superseded-by) checked by scripts/decisions_validate.py; a record is never deleted or line-edited to reverse a call — it is moved to docs/decisions/archive/ with status: superseded/retired and a reciprocal superseded-by/supersedes key pair to its replacement. |
