Stand up the 're-prove 100%' validation: Computus vs PHP easter_days(), a harvested missalemeum oracle fixture, the SSPX feed, and an optional Divinum Officium Perl oracle. Done when CI fails on any divergence from the oracles across the test date range.

Epic — child issues are tracked as sub-issues.

Epic complete — validation harness landed ✅

All six children are done; the engine is now re-proven against independent oracles on every PR, and CI fails on any divergence from the committed baselines.

Children

#46 — Computus cross-checked against PHP easter_days(), 1583–2200 + anchor dates.
#47 — pinned missalemeum oracle fixture (MIT, facts-only, 2024–2026) + reproducible harvester.
#48 — engine day() asserted field-by-field (class/colour/commemorations) vs missalemeum against a categorised 421-row known-differences baseline.
#49 — SSPX 1962 ordo as a second, independent witness (2024–2026); 85 class differences frozen with a three-way categorisation (71 corroborate base-1962 ranks; 12 seed the v0.2 overlay; 2 for adjudication).
#50 — optional Divinum Officium Perl adapter (availability-gated, graceful skip, unit-tested parser; live comparison maintainer-run).
#51 — explicit, named validate CI job (deps cached); added to the main ruleset's required status checks.

Real bugs the harness caught (fixed under this epic)

#422 — a coincident saint was displacing the Sacred Triduum.
#424 — commemoration-grade saints were being celebrated instead of commemorated (~50 days/yr).
Each was fixed as its own cited PR with the golden fixture re-frozen.

Follow-on

The baselines are living worklists, not rubber stamps (a regression and an improvement both fail until re-frozen). The 421-row missalemeum baseline + the corroborating SSPX rows are the base-1962 accuracy worklist tracked in #428; the SSPX-particular rows seed the v0.2 SSPX overlay.

Maintainer note

validate is now required on the main protection ruleset (done via API). No further action needed.

Closing as complete.
