+## Knowledge base
+
+A reviewed dossier for this repo lives in the second-brain vault:
+
+- Hub: `$SECOND_BRAIN_VAULT/knowledge/qqq/qqq-hub.md` — map of the whole QQQ knowledge base
+- Dossier: `$SECOND_BRAIN_VAULT/knowledge/qqq/repos/qbit-standard-process-trace.md`
+  (purpose, API surface, data model, QBit contract usage, licensing state, v4.0 impact)
+
+Reviewed at commit `0f2ec0339048` (branch `develop`, 2026-07-04).
+
+Key facts worth knowing before editing:
+
+- `main` was merged back into `develop` for QRun-IO/qqq#766, so `develop` has main's
+  Java 21 + Apache-2.0 LICENSE/NOTICE and the backend-activity-stats feature. Current
+  first-party pom, source-header and README license declarations also use Apache-2.0.
+- The qqq version comes only from `qbit-build-parent` 2.0.0 (qqq 4.0.0); do not re-add a
+  `qqq-bom-pom` import. `mvn -B verify -Pqqq-snapshot` checks against qqq `4.1.0-SNAPSHOT`
+  (override with `-Dqqq.snapshot.version=...`).
+- CHANGELOG.md text is copy-pasted from a different QBit; README code examples have drift
+  (nonexistent `producer.withTableMetaDataCustomizer`, table-name typos).
