+"""Build-time Sentinel-2 AOI bake for the curated Sentinel-2 (Track-B) tab — M5 Phase 4.
+
+**BUILD-TIME ONLY.** This is the *only* place Planetary Computer STAC / rasterio run. Its deps
+(``pystac-client``, ``planetary-computer``, ``rasterio``) are **build-time only** and are never
+added to ``app/backend/requirements.txt`` — the runtime Space image stays STAC-free and serves the
+baked cache exactly like the aerial curated mode (no runtime inference, no runtime STAC, no GPU).
+
+For each confirmed AOI (a real-world location with large, obvious change visible even at 10 m) it:
+
+1. Resolves the two confirmed low-cloud S2 **L2A** acquisitions from PC STAC (exact day + tile).
+2. Reads a fixed window of bands **B04,B03,B02,B08** (R,G,B,NIR) around the AOI centre.
+   Co-registration is trivial: each AOI's before/after share one MGRS tile → identical UTM grid, so
+   the same pixel window is aligned by construction (asserted).
+3. Harmonises reflectance across processing baselines (baseline ≥ 04.00 carries ``BOA_ADD_OFFSET``
+   ``-1000``; OSCD predates it) so both dates and the model input match training's radiometry.
+4. Renders 8-bit RGB display PNGs (joint percentile stretch so before/after are radiometrically
+   comparable).
+5. Runs the OSCD 4-band ONNX bundle **offline** with its own tile-stitch — deliberately *not* the
+   ``inference.py`` path, which is hard-coded RGB (3-band). ``inference.py._overlay_png`` IS
+   band-agnostic and is reused for the amber-fill + outline overlay.
+6. Bakes ``before.png`` / ``after.png`` / ``overlay.png`` + ``manifest.json`` + a predictions cache
+   under the gitignored ``app/backend/data/sentinel2/`` — the cache schema the app already serves.
+
+Usage (from the repo root, with the CPU ``.venv`` that has the STAC/rasterio deps)::
+
+    python app/backend/build_sentinel2.py                 # bake all AOIs
+    python app/backend/build_sentinel2.py --only gerd_reservoir --window 1536

+(reclamation, a filling reservoir, an airport built from farmland, a solar park, a desert city). Its
+before/after imagery and change prediction are **baked offline** by ``build_sentinel2.py`` and

+
+The registry reads ``<data_dir>/manifest.json`` (per-AOI metadata: title, MGRS tile, centre, the
+acquisition dates + cloud cover) and the baked ``<data_dir>/_predictions.json`` (the same cache
+schema ``inference.py.predict`` returns), and exposes both to the API.
