feat: simplify regional workbench language

 - Preserved separate Mol/regional series keys and honest partial-sector population and 10 m forest-area limitations.
 - Replaced internal provider identifiers with readable source labels in the primary map.
 - Added a provenance-gated full-Area query path for official pre-clipped datasets, avoiding redundant intersection of every feature against the same detailed municipal/regional boundary while preserving exact rectangle selection behavior.
-- Added focused scope filtering, command construction, boundary resolution, multi-NIS provenance, packaging and frontend-label tests.
+- Reduced a live complete-Kempen population/forest analysis from roughly 92 seconds to 2.8 seconds of API work while retaining the exact official totals.
+- Grouped dated population and forest snapshots into one current source plus an optional historical disclosure, translated remaining user-facing status/download/model-evaluation text and made municipality selection explicitly optional.
+- Added focused scope filtering, command construction, boundary resolution, multi-NIS provenance, full-Area correctness, temporal-language and frontend-label tests; the full readiness gate now passes with 571 tests.

+## Sprint 194 Regional official time series and full-Area performance (2026-07-14)
+
+Changed:
+- Generalized the explicit Statbel operator to the approved 28-municipality scope and added one coordinator for official 2021-2025 population plus 2013-2025 forest snapshots.
+- Added municipality-partitioned official 10 m WCS retrieval after the upstream response-size limit rejected a single full-region request; source partitions are resumable and mosaicked locally before exact region clipping.
+- Added a provenance-gated full-Area selection path for trusted pre-clipped operator datasets. Free rectangles, unrelated Areas and ordinary uploads continue to execute the normal PostGIS intersection path.
+- Grouped older dated snapshots behind `Historische meetmomenten`, replaced raw provider/type labels in the primary catalog and translated the remaining visible temporal, download, platform-status and detection-evaluation language.
+
+Live regional evidence:
+- Population datasets: five exact dated snapshots, 3,317 persisted `vector_features`; 2021 `489,927` inhabitants and 2025 `506,473`, a measured increase of `16,546` (`3.377%`).
+- Forest datasets: five exact dated snapshots, 273,669 persisted `vector_features`; 2013 `27,659.976 ha` and 2025 `27,410.687 ha`, a source-resolution change of `-249.289 ha` (`-0.9013%`).
+- All ten snapshots have one immutable dataset version and zero invalid, empty, non-4326 or source-ID-missing geometries. A repeated synchronization reused the same ten Dataset IDs without duplicates.
+- Complete-Kempen current analysis returns 506,473 inhabitants, 27,410.69 ha forest, 466,078 buildings, 88,332 water features, 84,504 roads and 415,288 parcels over 1,399.25 km2.
+
+Performance and runtime evidence:
+- Population full-Area API selection completed in `1.738 s`; forest completed in `1.083 s`. The browser rendered the full six-theme analysis and 2021-2025 comparison within the 3.5-second verification window, replacing the previous roughly 92-second forest-heavy workflow.
+- Tower health, PostGIS 3.6, required schema objects, Alembic head `202607140001`, frontend, API proxy and icon checks passed after deployment.
+- PyTorch `2.13.0+cpu`, Ultralytics `8.4.95` and the active local model file load successfully. The catalog exposes 24 local assets; the active seven-AOI profile remains review-required at F1 `0.5825` and was not blindly retrained.
+
+Tested:
+- `bash scripts/run_readiness_check.sh` passed with `571 passed`, backend compile, one Alembic head, frontend typecheck/build and live-smoke syntax validation.
+- Focused regional, temporal and end-user contract checks passed. The browser confirmed the complete regional default, six current themes, five population moments, exact temporal totals and no required project/region selection step.
+
+Next:
+- Complete the 48 false-positive and 48 false-negative operator review decisions, then use those decisions to build a justified next training corpus and expose the existing raster-to-tiles-to-detection workflow as one guided end-user action.
