 # Build Status — Active Blue Family Law (`activeblue_familylaw`)
 
-**All 14 roadmap steps are implemented, statically validated, and committed.**
+**All 14 roadmap steps are implemented, validated, and committed.**
 Module version `18.0.14.0.0`. Built on Odoo 18 Community.
 
-> ⚠️ **Tests have NOT been run in a live Odoo here** (no Odoo runtime/DB in the build
-> environment). Every step was validated statically (`scripts/validate_module.py`:
-> Python compile, XML well-formed, no Odoo-18-forbidden constructs, button→method
-> mapping, manifest/ACL integrity, view-field resolution, duplicate-id + action-ref
-> + load-order checks). **Run the tagged suites in your Odoo stack to confirm green.**
+> ✅ **Tests run green in a live Odoo 18:** `0 failed, 0 error(s) of 198 tests`
+> (installed clean into a throwaway DB on the local `odoo:18.0` image against
+> Postgres 16, then dropped — production DBs untouched). Also validated statically
+> via `scripts/validate_module.py` (Python compile, XML well-formed, no Odoo-18
+> forbidden constructs, button→method mapping, manifest/ACL integrity, view-field
+> resolution, duplicate-id + action-ref + load-order checks).
+>
+> Reproduce: see "Run the tests" below.
