+# F-060 — Implementer evidence
+
+## Scope delivered
+
+`scripts/generate-thumbnails.sh` was lagging behind the new resize contract
+introduced by F-059. It used `sharp().resize({ width: size, withoutEnlargement: true })`
+with no max-height cap, and it skipped already cached files. After F-059 the
+on-demand path (upload route, dynamic `/uploads/[...path]/route.ts` in all
+three apps) produces `fit: 'inside'` thumbnails bounded by `width * 1.4` height.
+Running the batch script did nothing for existing files — which meant the
+admin/frontend/storefront public uploads still held the legacy shape.
+
+## Changes
+
+### `project/scripts/generate-thumbnails.mjs`
+
+Two adjustments to keep the batch script aligned with the on-demand path:
+
+1. **Resize contract** — same `fit: 'inside'` and `MAX_HEIGHT_RATIO = 1.4`
+   bound as the upload route:
+
+   ```js
+   const maxHeight = Math.round(size * MAX_HEIGHT_RATIO);
+   await sharp(src)
+     .resize({ width: size, height: maxHeight, fit: 'inside', withoutEnlargement: true })
+     .jpeg({ quality: 80 })
+     .toFile(thumbPath);
+   ```
+
+2. **`FORCE` flag** — `FORCE=1` (or `FORCE=true`) skips the cache-skip
+   logic, so the script can regenerate thumbnails in place without deleting
+   the existing files first. Default behaviour (skip existing) is preserved
+   for normal cron runs.
+
+```bash
+FORCE=1 ./scripts/generate-thumbnails.sh
+```
+
+## Acceptance traceability
+
+| Acceptance criterion | How it is met |
+| -------------------- | ------------- |
+| Script uses `fit: 'inside'` with `maxHeight = size × 1.4` | Source updated, line-by-line equivalent to the upload route. |
+| `FORCE` flag regenerates existing cached thumbnails | New env var read at startup, controls the skip block. |
+| All cached thumbnails now use the new bounded-box behaviour matching upload route | After `FORCE=1 ./scripts/generate-thumbnails.sh`: 42 thumbnails regenerated (7 images × 2 sizes × 3 apps). On-disk dimensions verified with `file`. |
+| Non-square source thumbnails are not cropped | 600×800 source produces 40×53 and 200×267 (aspect 3:4 preserved). 800×800 source produces 40×40 and 200×200. 1×1 sources stay 1×1 (`withoutEnlargement` is intentional). |
+| `verify.sh` is green | Exit 0. |
+
