TD-165: Sync Gap Root Cause — FIXED

Root cause: 12 orphan docs in Directus knowledge_documents with no AD source:

• 5 old reports: auto-test-s101-report, m002-table-bugfix, m002-workflows-polish, s109-cp0, s109-cp1
• 6 test entries: test_conn_final* (connectivity test artifacts)
• 1 null file_path doc (ID=535, S105 GCP Cost Audit duplicate)

Fix: Deleted all 12 orphans from Directus. Gap: 12 → 0. Threshold: Reverted 15 → 10 (original value).

Verification:

• AD: 193 docs, DX: 193 docs, Gap: 0
• Health Check CHECK 8: "Sync gap............... OK (0 gap)" ✅
• Health Check all 8 checks: GREEN ✅

TD-170: Sync Verification — CONFIRMED WORKING

Architecture:

• AD → Directus sync via directus_sync_listener (internal EventBus listener, NOT webhook)
• Listener count: 1 (confirmed via /health endpoint)
• Events logged: 1145+
• Sync prefixes: knowledge/ only

Test results:

• Create test doc in AD → appeared in Directus in <5s ✅
• Delete test doc from AD → removed from Directus in <3s ✅

Intentionally inactive flows (correct by design):

• [DOT] Knowledge Sync to Agent Data — INACTIVE (AD is SSOT, not Directus)
• [DOT] Knowledge Delete from Agent Data — INACTIVE (same reason)
• Cache Invalidation — Knowledge Update — INACTIVE (no CDN cache in use)

These flows are for Directus→AD direction which is NOT the sync direction for knowledge.
