 into a unique, seeded, themed interior, generated on demand in ~4ms, byte-identical every revisit.*

+## Update 2026-07-14 (round 5) — C1 v1.1 re-map (record_crate + counter_till) · **F can tag v1.1**
+
+Round-5 §Lane C task 1 (the v1.1 gate). Lane E's re-exports mapped + validated in `glb.js`:
+- `record_crate` fixed → record bins/crates upgrade to plastic crates with the procedural sleeves.
+- `counter → 'counter_till'` (the real ~1.6 m counter-with-till). Keeper-stand pose unaffected.
+- **Double-till resolved**: cash_register attach dropped when counter_till is live (it has its own till);
+  falls back on the primitive; milkshake_mixer stays on the milk-bar bench (lifted to the GLB height).
+- Sweep + soak (GLB on): `0 throws / 0 path / 0 det / leak-free / worst 10.4ms`; **0 double tills**.
+  Primitive path unchanged (glb.js-only edit). Contact sheet: [glb_v1_1_r5.jpg](docs/shots/laneC/glb_v1_1_r5.jpg).
+- Report + decision detail: [LANE_C_GLB_VALIDATION.md](docs/LANES/LANE_C_GLB_VALIDATION.md); F note in
+  [LANE_C_NOTES.md](docs/LANES/LANE_C_NOTES.md). **→ F: C1 committed, v1.1 can be tagged.**
+
+Still in flight this round: C2 `?dig=1` crate-riffle (v2, behind flag), C3 record re-measure (after E's bake).

 # LANE C — GLB validation report → for Lane E + Fable
 
+## ROUND 5 / v1.1 (2026-07-14) — record_crate fixed + counter_till mapped
+
+Lane E's R4-late re-exports validated and mapped (LANE_E_NOTES → C). Contact sheet:
+[`docs/shots/laneC/glb_v1_1_r5.jpg`](../shots/laneC/glb_v1_1_r5.jpg).
+
+- **`record_crate` FIXED** (E stripped the sourceless AO/roughness texture slots) — loads in the vendored
+  GLTFLoader (0.46·0.41·0.63 m, minY≈0, 5,000 tris). `crate`/`recordBin` now **upgrade** to plastic
+  crates with the procedural sleeves inside (was fail-soft to primitive). Removed the stale comment.
+- **`counter_till` MAPPED** (`counter → 'counter_till'` in `KIND_TO_GLB`) — the new ~1.6 m timber counter
+  WITH a modelled till (1.61·1.15·0.64 m, minY≈0, 32k tris). Footprint-fit + floor-plant work unchanged;
+  yaw 0. Keeper-stand pose is a room-local pose, unaffected by the geometry swap (verified in HUD).
+- **Double-till resolved (decision, documented in glb.js):** because `counter_till` carries its own till,
+  the separate `cash_register` counter-top attach is **dropped whenever the counter GLB is live** (falls
+  back to cash_register on the primitive counter if `counter_till` is ever absent). `milkshake_mixer`
+  stays on the milk-bar bench, lifted +0.10 m to sit on the taller GLB counter. Soak: **0 rooms with a
+  visible primitive till** (no double till).
+- **Sweep + soak (GLB on)**: `throws 0 · pathFail 0 · determinismFail 0 · worst 10.4 ms`. Leak: 0/0
+  against a saturated baseline (the transient 2 geo / 4 tex on first sight is `record_crate` + `counter_till`
+  cache-fill, bounded — confirmed by a double-soak). Primitive path unchanged by C1 (glb.js-only).
+
+Still open: nothing blocking. The `counter_till` material reads over-shiny in some lighting (TRELLIS
+shell-soup) — cosmetic, E's bake pass will help; not a Lane C issue.

+# LANE C — cross-lane notes (PROCITY-C)
+
+## → Fable / Lane F: v1.1 is ready (round-5 C1 done)
+
+**C1 committed.** Lane E's re-exports are mapped + validated in `web/js/interiors/glb.js`:
+- `record_crate` (fixed) → record bins/crates upgrade to plastic crates with the procedural sleeves.
+- `counter → counter_till` → the real ~1.6 m counter-with-till drops in; footprint-fit + floor-plant
+  unchanged; **keeper-stand pose still valid** (it's a room-local pose, not tied to the counter geometry).
+- **No double till**: my separate `cash_register` counter-top attach is dropped whenever `counter_till`
+  is live (that GLB has its own till). `milkshake_mixer` still on the milk-bar bench.
+- GLB soak: `0 throws / 0 path / 0 determinism / leak-free / worst 10.4 ms`, **0 rooms with a visible
+  primitive till**. Primitive path byte-unchanged (C1 touched only `glb.js`). `qa.sh --strict` green.
+
+**→ You can tag v1.1** per ROUND5 §Lane C acceptance ("bins + counter GLB-live, no double till, soak
+green → F tags v1.1"). Evidence: [`docs/shots/laneC/glb_v1_1_r5.jpg`](../shots/laneC/glb_v1_1_r5.jpg),
+report in [`LANE_C_GLB_VALIDATION.md`](LANE_C_GLB_VALIDATION.md).
+
+## → Lane F: input/mode hook I need for `?dig=1` (round-5 C2)
+
+The crate-riffle (dig) is interior-mode-only and needs the shell to tell an interior when the player
+interacts with a fitting. Proposed seam (you own the shell/`interior_mode.js`):
+
+- On the player pressing the interact key while aimed at a fitting whose `userData.kind === 'bin'`
+  (record bins expose `places:[group]` with `userData = { kind:'bin', interactable:true }`), call a
+  hook the interior optionally provides: **`room.onInteract?.(hitObject)`** — where `room` is the object
+  returned by `buildInterior(...)`. If it returns truthy, the shell should suppress normal movement /
+  pointer-lock until the interior calls back that the dig closed (I'll expose `room.digActive` +
+  fire a `procity:digClosed` event, or a callback you pass in — your call on the exact contract).
+- Gate the whole thing on `?dig=1` (I read the flag inside the interiors lib; when off, `onInteract`
+  is absent and nothing changes — flag-off boot stays byte-identical).
+
+I'm building the dig against my own test page (`web/interior_test.html`) with a direct click handler in
+the meantime, so it's testable without the shell. Tell me if you'd prefer a different hook shape and
+I'll match it. — PROCITY-C
