CC 2.1.152 umbrella tail

The last 4 adoption issues — all awareness/catalog-class, no feature code. Closes the umbrella except #2045 (backlog).

Re-scope note: #2032 was framed as "the substantive feature." On reading the hook-contract spec (a curated subset, missing 7 events types.ts already has) with zero ork consumer, a behavior hook would be speculative YAGNI — so it's a 1-line type entry, not a feature.
