 ## Acceptance
 
-- ❌ HUD scene `src/game/engine/scenes/ui/lens_switcher.tscn` (or equivalent) exposes a horizontal lens picker with one button per supported lens.
-- ❌ Lens enum sourced from JSON manifest `public/resources/ui/lenses.json` — no hardcoded GDScript list.
-- ❌ Renderer reads the active lens via the existing tile-meta bridge and tints overlays per the lens's colormap entry.
-- ❌ Hotkey cycling (e.g., `Tab`/`Shift+Tab`) reuses the `p2-03` hotkey-cheat-sheet registry.
-- ❌ EventBus signal `lens_changed(lens_id: String)` emitted on switch; renderer listens.
-- ❌ Proof scene under `src/game/engine/scenes/tests/` captures one screenshot per lens; phase-gate accepted via `tools/screenshot.sh`.
-- ❌ `--headless` GUT test asserts the lens registry parses and the EventBus signal fires on simulated switch.
+- ✓ HUD scene `src/game/engine/scenes/ui/lens_switcher.tscn` (+ `lens_switcher.gd`) exposes a horizontal lens picker with one button per supported lens, grouped by `lens_categories.json` order. Mounted by `world_map_hud.gd::_build_lens_switcher()`.
+- ✓ Lens enum sourced from JSON manifests under `public/resources/lenses/*.json` (excluding `lenses.schema.json` and `lens_categories.json`). No hardcoded GDScript list — `lens_switcher.gd::_load_lenses()` walks the directory and parses each file.
+- ✓ Renderer reads the active lens through the existing `EventBus.map_overlay_changed(mode)` bridge (compat-emitted alongside the new `lens_changed`). `hex_overlay_renderer.gd` already consumes the matching mode strings (`temperature`, `moisture`, `pressure`, `humidity`, …). Additive only — no renderer refactoring.
+- ✓ Hotkey cycling: actions `ui_map_lens_next` (Tab) and `ui_map_lens_prev` (Shift+Tab) registered in `project.godot`. The `ui_map_` prefix is auto-picked up by the `p2-03` `hotkey_sheet.gd` bucket rule, so the cheat sheet surfaces the new keys without further wiring. `lens_switcher.gd::_unhandled_input()` handles them.
+- ✓ EventBus signal `lens_changed(lens_id: String)` added in `event_bus.gd`; widget emits it (and the legacy `map_overlay_changed`) on every switch.
+- ❌ Proof scene `src/game/engine/scenes/tests/lens_switcher_proof.tscn` (+ `.gd`) exists and is wired to capture one screenshot per loaded lens, but the screenshot run itself (via `tools/screenshot.sh` on the headless host) has not been performed in this session. Phase-gate evidence pending.
+- ✓ `--headless` GUT test `src/game/engine/tests/unit/test_lens_switcher.gd` asserts the lens registry parses (at least one lens, `temperature` present) and that both `EventBus.lens_changed` and the compat `EventBus.map_overlay_changed` fire on `set_active_lens` (including the empty-string clear case).
