   current-state sync → historical sync + company matching → scheduler/admin
   toggle → UI — each phase is a hard dependency on the previous, no
   parallelization within this milestone

 - Phase 10 isolates OAuth2 client-credentials auth + the full PAX8 schema
   migration before any sync logic is written, to de-risk the new external
   integration early
+
 - PAX8-08 (read-only guarantee) and PAX8-11 (flag don't guess) are treated as
   constraints verified within their natural sync phase (11 and 12
   respectively), not standalone phases
+
 - PAX8-12 (admin resolves flagged matches) is delivered on the `/pax8` page
   itself (Phase 14) rather than a separate `/admin` surface — `/pax8` is the
   dedicated home for this integration's data and review workflow
