CATCHUP run for Admin[00] only (Master/Builder both live, stayed clear). Read broadcast 43 in full. Investigated and fixed Builder's ORIENT-REG.md doc-vs-code mismatch report -- found it was bigger than reported (all 5 gov file types wrong, not just 2). Corrected ORIENT-REG.md, verified live, D742 logged. Read Master's actual gov file content to sanity-check the fix, found a stale contradictory claim in knowledge-10.md, flagged via inbox 818 rather than editing directly. SYNC at close confirmed Master fixed it same-day and filed T757 for a related finding. Also picked up 3 broadcasts on backend nav/tooling work done by Claude Code under system 00 identity this session (not reviewed in detail).

Fixed ORIENT-REG.md gov file naming table (5 types corrected to DECADE suffix). Logged D742. Flagged Master's stale gov-file content via inbox 818, confirmed resolved via SYNC pickup. Updated handoff-00.md twice, appended LEGACY-00.md, logged K228/K232/K233/K234/K255/K263 to memory pipeline. Closed T739 (BACKUP-REG.md registry gap) earlier same day.
