+## Sprint 225 - Governed ALZ edition probe (2026-07-16)
+
+Implemented:
+- Extended the existing explicit source-catalog audit with the exact official
+  ALZ agricultural-use parcel publication page. The parser is bounded and
+  fail-closed to the canonical HTTPS release path plus exact
+  `agpa_<year>_<date>_public.zip` link identities.
+- Kept the edition model honest: the retained local `2025-definitive` Dataset
+  compares with official `2025-v3`; the current `2026-v1` snapshot is visible
+  as provisional and cannot trigger or justify historical replacement.
+- Reused the canonical source-catalog API envelope, cache, operator command and
+  Status surface. No archive, feature, raster or model is fetched and no
+  Dataset/PostGIS mutation, scheduler or migration was introduced.
+- Propagated the ALZ release URL through backend settings, Compose, the Unraid
+  environment/template/launcher and operator documentation. An odd final
+  source-status card spans the full grid width for a balanced desktop layout.
+
+Validation:
+- The live official page probe returned `available`, definitive `2025-v3`,
+  current provisional `2026-v1`, both required evidence markers and 19
+  validated publication links without requesting an archive.
+- Focused source-catalog coverage passed with 13 tests, including release-page
+  redirects, untrusted archive hosts, missing current snapshot, definitive
+  year ordering, cache bypass and disabled/network-free behavior.
+- Complete readiness passed with 790 backend tests, 110 documented routes, one
+  Alembic head, frontend typecheck and production build. Static Alembic SQL and
+  live-migration script syntax also passed.
+- Tower was rebuilt from commit `0a23e34`; the all-in-one container became
+  healthy on port 1202, PostGIS 3.6 answered, required schema objects passed
+  and Alembic remained at `202607160001`.
+- The live regional API reported three available providers and no edition
+  differences. Browser verification showed `3/3 bereikbaar`, ALZ
+  `bereikbaar / zelfde editie`, `Publicaties: 2/2 bevestigd`, the provisional
+  warning and zero console warnings/errors.
+
+Boundary:
+- The probe is release evidence only. A future definitive campaign still
+  requires human confirmation and the existing governed ALZ operator; no
+  automatic ALZ refresh has been enabled.
