Migrate #406 (ci.runner-placement) and #412 (ci.peak-anon-measurement) to the lifecycle schema as exemplars; #390 and #411 confirmed prose-only (no standalone record). Dogfood the append-only->lifecycle supersession: docs.append-only-guard moved to archive/, superseded by new active docs.decision-lifecycle. Stand up docs/decisions/archive/ + migration-map.md.

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 Superseded/retired history lives in archive/.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every decision ## record (active or archived) carries a 5-field metadata block (key, status, since, supersedes, superseded-by) checked by scripts/decisions_validate.py; a record is never deleted or line-edited to reverse a call — it is moved to docs/decisions/archive/ with status: superseded/retired and a reciprocal superseded-by/supersedes key pair to its replacement.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