R-459 CLOSED (MariaDB converts itself, proven by harness + live), golden 0.236.0 (R-467), the golden waiver (R-468)

Operator rulings 2026-09-13, both shipped the same day:
- MariaDB finishes its own conversion (catalog eec1228/bd32830/3525e35). Harness E3/E3b `proven`
  with engine_state_after "already upgraded to 12.3.3-MariaDB [exit=1]", the skip line gone, C3
  still `failed`; landed on demo-hp through the real 15-min cycle, nothing recreated, one deliberate
  restart logged "MariaDB upgrade not required" with the app serving. Evidence:
  documentation/audits/r459-close-2026-09-13/. The engine-major rule + gate keep every engine
  inside its major until Slice 4 (R-448) — removal tracked as R-469.
- Goldens on a cadence, not per release. golden_currency_gate.py reads a dated waiver
  (documentation/tests/golden-waiver.yml, <= 14 days, row-bound): valid + BEHIND -> loud advisory,
  exit 0; expired -> red again naming the date; UNRECORDED (R-385) never covered; malformed -> 2,
  never 0. Tests cases 5-15 incl. the R-421 decoy; red-proof old-vs-new on the real behind tree.
  R-242's vouch half stays open. Cadence in RUNBOOK-manual-build.md §4.2 + the checklist.
- Golden 0.236.0 baked, round-tripped, vouched, floor raised 0.232.0 -> 0.236.0
  (documentation/tests/golden-0.236.0-2026-09-13/) — the last per-release bake; the waiver was
  issued AFTER it landed. No --no-verify anywhere in this session.

Rows: R-459 CLOSED, R-467 CLOSED, R-242 narrowed; R-468/R-469/R-470/R-471 opened. 09 §3 gains
decisions 5 and 6; STATUS items 11 and 12 closed; CONTEXT records the cadence ruling.
