SESSION START DRIFT VERIFICATION, 29 July 2026, fourth session of the day. Run BEFORE any change.
HEAD 0e967d6, 417 commits, working tree CLEAN, stash EMPTY.

STATE MATCHES THE HANDOFF EXACTLY, which is the first thing worth saying. The handoff recorded 415 commits at
aa06b6c; HEAD is two commits later because the handoff commit and the superseded handoff demotion followed it.
Every other number it recorded is reproduced below unchanged.

1. FROZEN SCORING ENGINE
   anchor e74fd2e exists:           yes, ASSERTED before the diff is trusted
   path files at anchor / at HEAD:  10 / 10, ASSERTED non empty at both ends
   engine diff:                     0 lines
   control, nonexistent commit:     prints 0 lines, caught by the anchor assertion
   control, a real diff elsewhere:  auth/service.go 120 lines, detector proven live
   Both fail open modes stay guarded. This check has failed open twice in this build's history.

2. NO PYTHON
   .py on disk: 0.  Control: one planted, detector saw 1, removed.

3. NO DASHES IN AUTHORED PROSE, em and en counted as occurrences
   BUILD_STATE.md 0/0, POSITIVE_CONTROL_LIBRARY.md 0/0, BUILD_CONTINUATION_PROTOCOL.md 0/0,
   CREDENTIAL_CONSUMERS.md 0/0, GATE_E.md 0/0
   Control: a planted em dash was counted as 1.

4. SECRET SWEEP
   working tree CLEAN. Control: planted credential DETECTED by name.
   SCOPE LIMIT, and it is finding four of the four still open: this sweep sees the REPOSITORY only. Extending it
   out of repo is scheduled work in this session.

5. THE MERGE GATE AND THE SUITE
   make build-test-gates PASS. verify-backdoor PASS. verify-fips PASS.
   55 packages ok, 0 FAIL.

6. SCHEMA VERSIONS, QUERIED PER DATABASE, NEVER SUMMARIZED
   control plane  100.77.114.40:5433/missionmatch         v84
   tenant         100.94.8.94:5432/missionmatch           v84
   staging        100.94.8.94:5432/missionmatch_staging   v84
   All three level.

7. PRODUCTION
   public site 200 over HTTPS.
   build routes DARK, unauthenticated: approve 404, scope 404, tracked 405.
   POSITIVE CONTROL, GET /api/auth/csrf: 200, so a uniform 404 cannot be a dead host.
   Bubbles healthz 200, megamind-agi healthz 200, staging healthz 200.
   production api sha 8f24414531e80a9a, UNCHANGED, no build feature shipped.
   zero failed units. root disk 82 percent, below the 85 percent alert threshold.

8. ENVIRONMENT
   All four hosts reachable: Bubbles, M4, VALKYRIE, and megamind-agi through the WSL bridge.

VERDICT: NO DRIFT. Nothing changed under the build between sessions, the freeze holds, and every check that
could pass by doing nothing carries a control that fired. Recorded before any change.
