Give street props colliders, zoned placements and variants

Props were decoration: the guard and guests walked straight through benches,
bins, bollards and planters. They now block movement and steer guests around.

Collision
- _add_prop_model() fits a StaticBody3D from the model's mesh bounds in
  holder-local space: a cylinder for bollard/bin/hydrant, a box otherwise, so
  placement rotation and variant scale carry over.
- Fallback primitives go through the same fit, so a missing .glb cannot silently
  remove collision.
- Each prop also publishes a NavigationObstacle3D; NpcAvatar enables agent
  avoidance and moves with the safe velocity from velocity_computed. The navmesh
  stays a flat walkable plane and avoidance does the steering.

Placement
- PROP_PLACEMENTS groups furniture by entrance, mid-block and curb zones, with a
  static placement_problems() validator for bounds, overlap/min-spacing,
  duplicates, and the door/steps/guest-lane exclusions.
- variant_for(index) gives deterministic yaw jitter, subtle scale, and optional
  clutter (bag by the bin, crate by the newspaper boxes, cone by the hydrant).

Verification
- New windowed smoke_props.gd: guard walks into a bench and stops; a guest
  headed beyond the bench routes around it and never enters the collider.
- Headless 182 -> 187: placement validation and its failure modes, variant
  determinism/range, collider + obstacle on every placed prop, fallback collider.
- Other smokes (PLAN verbs, crowd, emergency, timeline) still pass; Python
  tooling 53/53; screenshots recaptured; compare 9 good / 0 bad.
- Version 0.4.0. TODO: collision/placement section moved to DONE; prop pipeline
  checks remain.

+
+Completed 2026-10-31 (working tree). Headless **153/153**.
+
+Verified via API+host credentials (2026-10-31):
+
+- [x] Repo is **public** (`private:false`) and account has admin rights.
+- [x] Release `v0.2.1` now carries all five artifacts (portable binaries + NSIS installer +
+      AppImage).
+- [x] **Host setting applied**: `[service] REQUIRE_SIGNIN_VIEW = false` in `/etc/gitea/app.ini`
+      (backup written alongside), Gitea restarted. Verified anonymously: repo page 200, API 200,
+      and a release asset downloads with the full 50.8 MB AppImage.
+
+## Release pipeline follow-up
+
+Completed 2026-10-31 (working tree). Headless **153/153**.
+
+- [x] Fix `tools/publish_release.sh`: the `~/.git-credentials` branch never set `AUTH`,
+      so every tag build since v0.2.2 failed to publish.
+- [x] Add a `github.token` fallback in `.gitea/workflows/build.yml` (the repo has no
+      `GITEA_TOKEN` secret).
+- [x] Fall back to the checkout's git extraheader when no token/credentials exist (the
+      Gitea runner does not expose `github.token`).
+- [x] Uploads now fail loudly and the release is verified to carry every artifact
+      (a silent HTTP 4xx used to leave an empty release with a green job).
+- [x] Host disk expanded to 16G; v0.2.0 and v0.2.9 releases restored from the local artifacts.
+- [x] Host maintenance via `root@192.168.88.30`: apt cache cleaned and journald capped
+      (`SystemMaxUse=300M` in `/etc/systemd/journald.conf.d/99-size.conf`); ~7.6G free.
+- [x] Verified end to end: tagging v0.2.12 produced a release with all five artifacts
+      (AppImage, Linux, macOS, NSIS installer, Windows) from CI, with no repo secret.
+- [x] Backfill decision: v0.2.4–v0.2.8 stay superseded; their tags and source remain, and the

+
+## Screen design references (QA tooling)
+
+Completed 2026-10-31 (working tree). 30 Python tooling tests pass; the live judge run classed 3 captures as match and 3 as review (concept mockups are more stylised), with no confident mismatch.
+
+- [x] `tools/screen_designs.py generate` writes one reference design per screen
+      (from the `docs/` descriptions) to `docs/screens/designs/`, with an offline
+      `--draft` wireframe mode and an OpenRouter `--ai` mockup mode.
+- [x] `tools/screen_designs.py compare` checks `docs/screenshots/*.png` against the
+      designs (aspect ratio, size, blank-frame, and layout/palette/detail drift).
+- [x] Vision-model judge for semantic screenshot comparison: `judge` sends the
+      capture + reference design to a vision model, classes verdicts as
+      match/review/diff with a confidence threshold, supports `--dry-run`, `--json`,
+      `--only`, and `--model`, and reads the repo `.env` for the API key.

+
+- [x] Author venues as `.tres` resources: `tools/export_venues.gd` writes
+      `content/venues/<id>.tres` from the factory, and a test loads them back to check
+      nothing is lost (events, profiles, policy, phases, door lines, locations).
+- [x] GUT decision: **not adopted.** The custom headless runner (`src/test/test_runner.gd`)
+      already covers 157 assertions without an editor plugin, runs in CI, and keeps the
+      project dependency-free; adding GUT would duplicate coverage and require the editor.
+
+## In-Game Scene Examples
+
+Completed 2026-10-31 (v0.3.0 working tree). `python3 tools/screen_designs.py list` reports
+19 screens (8 scene, 11 UI); the Python tooling tests pass.
+
+- [x] Extend the `tools/screen_designs.py` catalogue with the screens that exist in code but
+      had no reference: wand screening, Joke Shop door queue, TV Studio celebrity arrival,
+      crowd panic, responder arrival, body-camera timeline, escalation HUD.
+- [x] Add a `list` subcommand so the catalogue is inspectable without generating images.
+- [x] Cover the new entries with `tools/test_screen_designs.py` assertions.
+- [x] Regenerate the deterministic draft references under `docs/screens/designs/`.
+      (`generate` now keeps existing references unless `--force` is passed, so a draft run
+      cannot replace an AI mockup; `--only` selects a subset.)
+
+## Rendering Quality
+
+Completed 2026-10-31 (v0.3.0 working tree). Screenshots regenerated; `screen_designs.py
+compare` reports 6 good / 0 bad.
+
+- [x] Add a shared surface-material module (`src/game/materials.gd`) with
+      roughness/metallic/uv-scale profiles per surface and a single environment tune-up
+      (tonemap, glow, fog, shadows).
+- [x] Rebuild `WorldBuilder` surfaces with the material profiles and add street detail:
+      window bands, door trim, bollards, bench, bin, curb, planter foliage.
+- [x] Per-phase environment values (fog, sky energy, glow) so night reads darker and the
+      marquee glows.
+- [x] Improve NPC silhouette and materials: per-role clothing palette, caps/hoods/backpacks,
+      sleeves and hands, walking leg swing.
+- [x] Cover materials/environment/avatar helpers with headless tests
+      (`test_materials.gd`, `test_target_cycle.gd`).
+
+## AI 3D Model Tooling
+
+Completed 2026-10-31 (v0.3.0 working tree). `model_pipeline.py build` + `audit` pass for all
+six props; `test_generated_props.gd` proves they import as scenes and that the world places
+them.
+
+- [x] Add `tools/model_pipeline.py`: prop catalogue, deterministic low-poly GLB builder,
+      OpenRouter concept-image generation, palette sampling and GLB audit.
+- [x] Add `tools/test_model_pipeline.py` (valid GLB structure, deterministic output, audit
+      failures, sRGB→linear conversion, role assignment).
+- [x] Generate the prop models into `assets/models/generated/` and import them.
+- [x] Load the generated props in `WorldBuilder` with a procedural fallback when the GLB is
+      missing.
+
+## Controls, Movement and NPC Selection
+
+Completed 2026-10-31 (v0.3.0 working tree). The windowed smoke now covers wheel cycling and
+right-click clearing; the headless suite passes 177/177.
+
+- [x] Record the re-evaluated control model as ADR-0011.
+- [x] Rank focus candidates by view angle then distance (`NpcFocus.rank_indices`) instead of
+      insertion order.
+- [x] Add mouse-wheel target cycling next to `Tab`, right-click clearing focus, and a `Shift`
+      precision walk speed.
+- [x] Show the nearby-candidate count and the cycle hint in the HUD.
+- [x] Cover ranking, cycling and walk speed with tests, then re-run the windowed smoke.
+
+## Web Export Build Target
+
+Completed 2026-10-31 (v0.3.0). Headless **181/181**; `godot --headless --export-release "Web"`
+produces a 63 MB static bundle and it serves locally with HTTP 200s for html/wasm/pck.
+
+- [x] Add a `Web` preset to `export_presets.cfg` using `variant/thread_support=false` so the
+      build runs on plain static hosting without COOP/COEP headers.
+- [x] Export to `build/web/` and package `build/step-line-web-<version>.zip` from
+      `tools/build_releases.sh` (zip or Python fallback).
+- [x] Publish the web zip with the desktop artifacts (`tools/publish_release.sh`).
+- [x] Cover the preset, the non-threaded choice, and the release wiring in
+      `src/test/tests/test_web_export.gd`.
+- [x] Document the artifact in `docs/RELEASING.md`, the README gallery/status, and `PLAN.md`.
+
+## Prop Texture Atlas
+
+Completed 2026-10-31 (v0.3.1). Headless **182/182**, Python tooling **53/53**; screenshots
+regenerated and `screen_designs.py compare` still reports 6 good / 0 bad.
+
+- [x] `model_pipeline.atlas_for()` packs each prop's palette roles into one small power-of-two
+      PNG and a matching metallic/roughness atlas (roughness in G, metallic in B), with nearest
+      sampling so a palette cell stays a flat colour.
+- [x] `build_glb()` merges every part into a single primitive with per-vertex atlas UVs and one
+      material (`baseColorTexture` + `metallicRoughnessTexture`), so a prop is one draw material
+      instead of one per part.
+- [x] `audit_glb()` checks the single-material/atlas contract (one material, both textures,
+      TEXCOORD_0 on every primitive, two images).
+- [x] Tests: atlas determinism and power-of-two sizing, UV range, palette override reaching the
+      atlas, and a Godot test that each imported prop scene uses exactly one material.
+- [x] Removed the now-unused sRGB→linear factor helpers (colours travel in the sRGB texture).
+
+## Complete AI Mockup Set
+
+Completed 2026-10-31 (v0.3.2). All 19 catalogue screens now have an AI reference; Python
+tooling **53/53**.
+
+- [x] Generated mockups for the seven entries that only had wireframes: wand screening,
+      Joke Shop queue, TV Studio arrival, crowd panic, responder arrival, body-camera
+      timeline, escalation HUD.
+- [x] `generate` loads `.env` like `judge` already did, so `--ai` works without exporting
+      `OPENROUTER_API_KEY` by hand.
+- [x] Verified every reference is 1280x720, reviewed the new images visually, and confirmed
+      `list` reports 19 designs (12 kept, 7 new).
+
+## Staged Captures For The New Screens
+
+Completed 2026-11-01 (v0.3.3). `screen_designs.py compare` reports **9 good / 0 bad**;
+vision judge: wand **match** (0.90), timeline **match** (1.00), escalation **review**, 0 diff.
+Python tooling **53/53**, headless **182/182**.
+
+- [x] `capture_screenshots.gd` now continues past the night set: switches to The Joke Shop,
+      stages a guest, retries the wand until it alerts (falls back to the documented keys
+      false alarm), applies formal warning + blocking, and opens the body-camera timeline.
+- [x] New captures `07-wand-screening.png`, `08-escalation-hud.png`, `09-body-camera-timeline.png`
+      added to `docs/screenshots/` and to the README gallery.
+- [x] Wired `ref` for `wand_screening`, `escalation_hud` and `body_camera_timeline` so
+      `compare` and `judge` include them (9 of 19 screens now have a staged capture).
+- [x] Regenerated the escalation HUD mockup as a third-person over-the-shoulder night shot so
+      the reference matches the game camera.
+- [x] Added `Hud.clear_log()` so staged captures drop target-cycling noise; the escalation shot
+      keeps the real reaction lines.
+
+## Prop Collision And Placement
+
+Completed 2026-11-01 (v0.4.0). Headless **187/187**, Python tooling **53/53**, the new
+`smoke_props.gd` passes windowed, and `screen_designs.py compare` still reports 9 good / 0 bad.
+
+- [x] Every generated prop now gets a fitted static collider: a cylinder for bollard, bin, and
+      hydrant, a box for everything else. The collider is computed from the model's mesh bounds in
+      holder-local space, so placement rotation and variant scale carry over.
+- [x] Added `smoke_props.gd` (windowed): the guard walks into a bench and stops instead of passing
+      through it; a guest heading for a point beyond the same bench routes around it with
+      navigation avoidance and never ends up inside the collider.
+- [x] Props publish a `NavigationObstacle3D` footprint, and `NpcAvatar` enables agent avoidance with
+      a `velocity_computed` callback. The navmesh stays a flat walkable plane; avoidance does the
+      steering around street furniture.
+- [x] Replaced the hard-coded prop calls with `WorldBuilder.PROP_PLACEMENTS`, grouped by entrance,
+      mid-block, and curb zones, with a static `placement_problems()` validator for bounds,
+      overlap/min-spacing, duplicates, and the door/steps/guest-lane exclusions.
+- [x] Deterministic variants per placement (`variant_for`): yaw jitter, subtle scale, and optional
+      procedural clutter (bag by the bin, crate by the newspaper boxes, cone by the hydrant), so
+      repeated props stop looking cloned.
+- [x] Fallback primitive props go through the same bounds fit, so a missing `.glb` cannot silently
+      remove collision; a unit test covers the fallback body, shape, width, and navigation obstacle.
+- [x] Tests: placement validation and its failure modes, variant determinism/range, colliders on
+      every placed prop (including obstacle presence), and the fallback collider path.

+  `src/test/tests/test_web_export.gd`.
+- **Prop atlas (v0.3.1):** `model_pipeline.atlas_for()` builds a per-prop power-of-two PNG with

+  GLB merges all parts into one primitive with constant per-vertex UVs (cell centre) and a single

+  the texture, so the old `srgb_to_linear`/`_linear_rgba` helpers were removed. `audit_glb` fails
+  if a prop is not exactly one material or misses TEXCOORD_0/images.
+- **Mockups complete (v0.3.2):** `docs/screens/designs/` holds AI references for all 19
+  catalogue screens. Only the six staged captures (01–06) are compared/judged; the other 13
+  have no `capture`, so adding staged captures for the wand panel, timeline and escalation HUD
+  would extend automated visual checks. `generate` now calls `_load_env_file()`.
+- **Staged captures (v0.3.3):** `capture_screenshots.gd` now emits nine shots. States 7–10 switch
+  to The Joke Shop at elapsed 620 s (EVENING has routine spawns; LATE has none), retry the wand
+  until it alerts, then jump to 760 s after staging for night lighting. The timeline needs
+  `recorder.close_all_open()`, because `to_dict()` only lists closed incidents. The escalation
+  HUD mockup is third-person now; `judge` still classes it `review` (no diff).
+- **Prop collision (v0.4.0):** `_add_prop_model()` fits a `StaticBody3D` from the model bounds
+  (cylinder for bollard/bin/hydrant, box otherwise) and adds a `NavigationObstacle3D`; NPC agents
+  enable avoidance and move with the safe velocity from `velocity_computed`. The navmesh stays a
+  flat plane, so avoidance (not a baked mesh) routes guests around props. Placements live in
+  `PROP_PLACEMENTS` with `placement_problems()` validation; variants come from `variant_for(index)`.
+  `smoke_props.gd` must be windowed because the guard reads captured-mouse input.
+- **Presentation pass remaining (TODO):** NPC characters and player movement. Grounding facts: the
+  NPC rig is rigid capsules with a whole-limb swing, and `guard_controller.gd` uses one `accel`
+  value. Each task should get its own windowed smoke or capture where it changes feel/looks.

 ## Current State
 
+- **v0.3.0 pass (2026-10-31, uncommitted):** rendering, generated prop models, screen
+  catalogue, aim-free selection. See ADR-0011 (selection) and ADR-0012 (materials/props).
+  - `src/game/materials.gd` (`SurfaceMaterials`) is now the single source of surface
+    recipes + `configure_environment()`. `GameManager.PHASE_LIGHTING` gained
+    `exposure/glow/fog_color/fog_density/fog_energy/contrast/saturation/ambient_energy`.
+    Renderer is **GL Compatibility**, so SSAO/SSIL are unavailable; glow+fog+ACES are used
+    instead and unsupported settings are ignored rather than gated in code.
+  - World: scaled brick (uv 22,10), framed windows with per-window night emission
+    (`i % 3 != 2` lit), stone base course, door trim/handles, curb, lane dashes (the old
+    loop had `Vector3(i * 0.0, …)` and stacked every dash at x=0), street lamps use the
+    metal profile. The two flat planters that clipped the steps were removed.
+  - `tools/model_pipeline.py` builds `assets/models/generated/*.glb` (bollard, bench,
+    trash_bin, planter_box, newspaper_box, fire_hydrant) from box/cylinder specs;
+    `WorldBuilder._add_prop_model()` loads them with a procedural fallback and records
+    `loaded_models` / `fallback_props`. **Gotcha:** glTF `baseColorFactor` is LINEAR —
+    writing sRGB made every prop pastel; `srgb_to_linear()` is applied in `build_glb`.
+    **Gotcha:** a new/changed `.glb` needs `godot --headless --path . --import` before
+    `ResourceLoader.exists()` / `load()` sees it (test_generated_props fails otherwise).
+  - `model_pipeline.py concept` (OpenRouter, reads repo `.env`) writes per-prop concept
+    sheets to `assets/models/concepts/`; `dominant_colors()` centre-crops and weights by
+    saturation (a grey studio backdrop otherwise wins), `assign_roles()` maps colours by
+    hue/value. Delete a concept file to fall back to the catalogue palette.
+  - NPC avatars: `outfit_for(type, seed)` (pure) gives shirt/trousers/hair/skin +
+    accessory (cap, hood, backpack, sunglasses, lanyard) and height scale; `_arms` and
+    `_legs` now swing (`limb_swing`) while walking. Keep `Rig/Head` named for focus.
+  - Selection: `NpcFocus.rank_indices` (angle then distance) — `pick_index` = first.
+    `GuardController.cycle_target(direction)` walks nearest-first `nearby_candidates()` and
+    sets `target_pinned`, which makes `_update_target()` skip the cone. `clear_target()`
+    sets `focus_suppress_s = 0.75` so the cone does not instantly re-acquire the person.
+    New input actions `walk_slow` (Shift), `cycle_target_next` / `cycle_target_prev`
+    (wheel down / up). Right click with nothing open clears focus (Esc still pauses).
+  - HUD: `nearby_label` + `set_nearby_hint(count)` show `hud.nearby`; `hud.controls` and
+    `hud.targeting` mention the wheel and Shift.
+  - `tools/screen_designs.py`: catalogue now 19 screens (added wand_screening,
+    joke_shop_queue, studio_arrival, crowd_panic, responder_arrival,
+    body_camera_timeline, escalation_hud), new `list` command, `generate --only/--force`
+    (existing designs are kept by default so a draft run cannot clobber AI mockups),
+    and `judge --dry-run` no longer raises `KeyError: 'class'`.
+  - Screenshot tool leak: `capture_screenshots.gd` intermittently prints
+    `ObjectDB instances leaked at exit`. Verified against a `git worktree` of HEAD~ — the
+    baseline leaks more often (3/3 vs 1/3), so it is a pre-existing quit-timing artifact,
+    not a regression. Normal boots are clean.
+
 - Access artifacts: `src/core/access_loadout.gd` builds from event `override_access` + venue policy.

+
+Decisions: [ADR-0011](docs/adr/0011-aim-free-selection-and-precision-walk.md) aim-free selection and precision walk, [ADR-0012](docs/adr/0012-surface-materials-and-generated-props.md) surface materials and generated props.
+
+The blockout look and the aim-first selection model were the two biggest gaps left by the control pass. This pass closes them without changing the game's rules.
+
+**Look.** Surfaces get real profiles instead of stock materials: brick is rough and finely tiled, concrete is rougher still, asphalt is smoother and damp-looking, glass is smooth and slightly metallic. The environment gains ACES tonemapping, soft glow, aerial fog and a mild grade, all driven by the same per-phase configuration that already moves the sun and sky. The facade gains framed windows that light up after dark, a stone base course, door trim and handles. Street furniture becomes real geometry: bollards, benches, bins, planters, newspaper boxes and a hydrant, built as `.glb` props by `tools/model_pipeline.py` with a procedural fallback. NPCs get per-role clothing palettes, small role accessories (cap, hood, backpack, sunglasses, lanyard), hands, shoes, and an arm/leg walk swing. The rule stays: the player judges people from clothes, props and behaviour, never from an archetype label.
+
+**Models.** Prop meshes are deterministic primitives, so the build works offline. An image model can supply the per-prop colour palette from a concept sheet; that is the only AI influence on geometry, and it is optional. Colours are converted from sRGB to linear before they reach glTF, because glTF factors are linear.
+
+**Selection.** The focus cone ranks heads by angle from the crosshair then distance. `Tab` and the mouse wheel cycle nearby people nearest-first and pin the choice, so aim-free play works. Right click clears focus and briefly suppresses re-acquisition. Holding `Shift` walks at half speed for close work at the door. Escape keeps its single meaning (close the top panel, otherwise pause).
+
 ## Design Direction
 
 The game should feel like a tense workplace simulation with occasional crisis moments. The most satisfying outcome is not overpowering an NPC; it is recognizing the situation early and resolving it calmly.

+is real 3D geometry generated by `tools/model_pipeline.py` and written to

+Each prop is a small list of boxes and cylinders, so `build` needs no network and
+the output is byte-identical between runs. `concept` asks an image model for a
+studio-style reference; `dominant_colors` and `assign_roles` then map that image's
+colours onto material roles (darkest → metal, warm saturated → wood, light grey →
+stone, green → foliage). glTF stores colours in linear space, so the tool converts
+the sRGB palettes before writing them. Re-run `build` and `godot --headless

-## Screen design references (QA tooling)
+- [ ] Add an idle layer: breathing, weight shift, occasional look-around, phone check, and

+- [ ] Add conversation gestures: facing the guard when addressed, talking hand movement, nodding,
+      backing away, and pointing, driven by the existing reaction/escalation events.
+- [ ] Improve the walk cycle: stride length tied to speed, foot planting without sliding, and a
+      distinct hurry/flee gait that matches `FLEE_SPEED`.
+- [ ] Stage a door queue: waiting offsets, one-at-a-time approach, no overlapping capsules, and a
+      step-aside after the admission decision.
+- [ ] Make reactions readable at a distance with body language plus a short icon/label
+      (rubberneck, panic, calm, angry) so crowd state is legible without the debug panel.

+- [ ] Re-measure the live-NPC budget with the full rig at `MAX_LIVE_NPCS`, and add a perf smoke
+      that fails when frame time crosses the documented budget.
+- [ ] Add tests for animation state transitions (idle → walk → react) and for queue spacing at
+      the door.
 
-- [ ] IDE/editor-based GUT integration. Until then the custom headless runner stays.
+## Better Player Movement
-- [ ] Optional later: author venues as `.tres` resources instead of `ScenarioFactory` functions.
+
+### Feel and handling
+
+- [ ] Split acceleration and deceleration in `guard_controller.gd` (faster stop than start, no
+      ice-skating), then tune `move_speed` and `accel` against a windowed feel pass.
+- [ ] Add step-up assist for kerbs and the entrance steps (about 0.3 m) and keep wall sliding
+      smooth so the guard does not stick on doorframes, railings, or prop colliders.
+- [ ] Add subtle head bob tied to stride and speed, a small FOV change in precision walk, and a
+      landing dip; expose a motion-sickness toggle in settings with persistence.
+- [ ] Give precision walk (Shift) visible feedback: a HUD state chip and an audio tick when it
+      engages, in addition to the slower speed.
+- [ ] Add surface-aware footsteps (concrete, asphalt, stone steps) with stride-synced timing and
+      a distinct landing sound, reusing the procedural audio helpers.
+
+### Input and accessibility
+
+- [ ] Add gamepad support: move/look actions, radial and action bindings, deadzone and look
+      sensitivity, with prompts that follow the active device.
+- [ ] Move the remaining hard-coded keys into `InputMap` actions and persist any remaps through
+      the settings panel (keyboard and gamepad).
+- [ ] Add a mouse-sensitivity and invert-Y setting if missing, and test the values survive a
+      settings save/load round trip.
+- [ ] Add movement tests: acceleration ramp, step-up height limit, precision-walk speed, wall
+      slide, and gamepad deadzone.
+- [ ] Run one windowed movement smoke per change above (walk the full block, climb the steps,
+      strafe along the wall) and capture a short screenshot set for the compare tool.
+
+## Future ideas (optional, not scheduled)
+
+- [ ] Live 3D body-camera replay (the timeline is text-only today).
+- [ ] Additional venues or seasonal events authored from the new `.tres` files.
+- [ ] Real voice/dialogue audio (the crowd bed and radio crackle are procedural).
+- [ ] Swap the primitive prop builder for an image-to-mesh model API behind the same
+      `assets/models/generated/<prop>.glb` contract.

+# ADR-0011: Aim-free target selection, precision walk, and focus clearing
+
+- **Status:** Accepted
+- **Date:** 2026-10-31
+
+## Context
+
+ADR-0007 and ADR-0008 split input into locomotion, look, and a focus cone. A pass over the resulting controls found four problems in play:
+
+1. **The cone ignored what the player sees.** `NpcFocus.pick_index` returned the first head inside the cone in group order, not the one nearest the crosshair. Two people in the cone gave an arbitrary pick.
+2. **`Tab` cycled in spawn order.** `GameManager._cycle_nearby_target` walked the `npcs` array, so "next" meant "next spawned", not "next nearest".
+3. **A cycled target was dropped within a few frames.** The cone re-evaluated every physics frame and cleared a target that was not under the crosshair after the 8-frame miss grace. Aim-free selection therefore only worked while the player also aimed.
+4. **There was no way to dismiss someone.** `Esc` pauses the shift and right click only cancelled modals.
+
+The movement pass also left one gap at the door: the only walking speed is 3.2 m/s, which overshoots when the player is trying to stand at a register or read an artifact at conversation distance.
+
+## Decision
+
+**Rank the cone by angle, then distance.** `NpcFocus.rank_indices` scores every head by its angle from the camera forward vector and breaks ties by distance; `pick_index` is the first ranked entry. The cone therefore picks the person closest to the crosshair, which is what the player is looking at.
+
+**Make aim-free selection authoritative.** `GuardController.cycle_target(direction)` walks `nearby_candidates()` — everyone within 12 m, nearest first — starting from the current target and wrapping in both directions. The chosen avatar is *pinned*: while a pinned target is alive the cone does not re-evaluate, so `Tab` and the mouse wheel produce a stable selection the player can then act on.
+
+**Bind the mouse wheel to the same ring.** `cycle_target_next` (wheel down) and `cycle_target_prev` (wheel up) are new input actions handled in `GameManager._handle_mouse_button`. `Tab` remains the keyboard path. The HUD prints how many people are in the ring (`hud.nearby`), so the player knows the control exists before they need it.
+
+**Right click clears focus, with a short grace.** With no modal open, right click clears the target and suppresses cone acquisition for `FOCUS_SUPPRESS_S = 0.75 s`. Without the grace the cone re-acquired the same person on the next frame, which made the control feel broken. Any explicit pick (cone or cycle) cancels the suppression.
+
+**Add a precision walk.** Holding `Shift` (`walk_slow`) multiplies the walk speed by `SLOW_WALK_FACTOR = 0.45`. This is a fine-positioning aid, not a sprint: PLAN.md deliberately excludes sprint and crouch, and this does not add a faster move.
+
+Escape keeps its current meaning (close the top modal, otherwise pause). Selection is not overloaded onto the same key.
+
+## Consequences
+
+### Positive
+
+- The focused person is predictable: the one nearest the crosshair, or the one the player explicitly cycled to.
+- Aim-free play works: cycle, act, cycle again, without fighting the cone.
+- Right click has an unambiguous "never mind" meaning while remaining a modal cancel.
+- Standing on a mark while reading an artifact is possible.
+
+### Negative
+
+- Two more input actions and one more piece of guard state (`target_pinned`, `focus_suppress_s`).
+- A cycled target stays selected until the player clears it, acts, or the avatar is freed; it does not expire on its own.
+- The 0.75 s suppression is a feel constant that may need tuning against play testing.
+
+## Follow-up
+
+- The action wheel (ADR-0009) and inspection panels still take `A`/`D`; the wheel owns those keys while it is open, and the guard is frozen then, so no conflict is observable.

+# ADR-0012: Surface material profiles and generated prop models
+
+- **Status:** Accepted
+- **Date:** 2026-10-31
+
+## Context
+
+The procedural street was built from `BoxMesh` primitives with `StandardMaterial3D` defaults: albedo colour (or a texture) and everything else stock. Every surface therefore shared one roughness, street furniture was a set of scaled boxes, and the sky was a flat `ProceduralSkyMaterial` with no tonemapping, glow, or fog. Captures looked like a blockout: brick tiles were metres wide, the sidewalk blew out to white, the facade had no windows, and night mode only switched the lamp bulbs and the marquee.
+
+Two constraints shaped the fix:
+
+- The project renders with the **GL Compatibility** backend so it stays small and portable, which rules out features that only exist in Forward+ (`SSAO`, `SSIL`).
+- The repo must build offline in CI, so any asset step has to work without a network or an API key.
+
+## Decision
+
+**One material module.** `src/game/materials.gd` (`SurfaceMaterials`) owns a named profile table (`brick`, `concrete`, `asphalt`, `awning`, `stone`, `metal`, `painted_metal`, `wood`, `cloth`, `skin`, `glass`, `rubber`) with roughness/metallic pairs, plus the recipes the world and avatars use (`brick()`, `concrete()`, `asphalt()`, `awning()`, `flat()`, `emissive()`, `glass()`, `window_pane()`). The world builder, the NPC avatars, and the prop fallbacks all call it, so a surface has one definition.
+
+**One environment tune-up.** `SurfaceMaterials.configure_environment()` applies ACES tonemapping, soft glow (for the marquee, lamp bulbs, and lit windows), aerial fog, and a mild contrast/saturation lift. `GameManager.PHASE_LIGHTING` now carries the per-phase values (`exposure`, `glow`, `fog_color`, `fog_density`, `fog_energy`, `contrast`, `saturation`, `ambient_energy`) next to the existing sun/sky entries, so a phase change still happens in one place. Features unavailable in Compatibility are ignored by the driver rather than gated in code.
+
+**Generated prop models.** `tools/model_pipeline.py` describes street furniture (bollard, bench, bin, planter, newspaper box, hydrant) as boxes and cylinders and writes binary glTF (`.glb`) into `assets/models/generated/`. Godot imports each file as a `PackedScene`, and `WorldBuilder._add_prop_model()` instantiates it with a procedural fallback when the file or its import is missing. The build is deterministic and needs no network.
+
+**AI only supplies colour.** `model_pipeline.py concept` asks an image model (OpenRouter, same backend as the texture tools) for one studio-style concept per prop. `dominant_colors()` reads the centre of that image and ranks colours by frequency weighted by saturation (a grey backdrop otherwise wins), and `assign_roles()` maps the result onto material roles by hue and value: darkest tone → metal, warm saturated tone → wood, light desaturated tone → stone, green tone → foliage. Colours are converted from sRGB to **linear** before they are written into glTF `baseColorFactor`, because the factor is linear space and writing sRGB made every prop render pastel.
+
+## Consequences
+
+### Positive
+
+- Surfaces read as materials: brick has fine, correctly scaled tiling, asphalt is smoother than brick, glass is smooth and slightly metallic, and the night sky carries warm lit windows.
+- Street furniture is real geometry with per-part materials instead of scaled boxes, and it costs ~700 triangles for the whole set.
+- The prop pipeline works with no key and no network; the concept step is optional and only changes colours.
+- Tests can assert material profiles, environment values, and GLB structure without rendering.
+
+### Negative
+
+- The generated models are low-poly primitives, not sculpted assets; they are an improvement in silhouette, not photoreal props.
+- Two colour spaces now exist in the tooling. `model_pipeline.srgb_to_linear` must be used for every colour written into glTF, which is easy to forget.
+- Concept images are per-prop inputs that have to be regenerated (and reviewed) when the art direction changes; a poor concept now produces a poor palette.
+- Compatibility rendering means no ambient occlusion, so contact shadows rely on the directional light only.
+
+## Follow-up
+
+- A 3D-model API (image-to-mesh) could replace the primitive builder behind the same `assets/models/generated/<prop>.glb` contract without touching `WorldBuilder`.
+- Texture atlases for the props would let them share one material instead of one per part.

+"""Build the low-poly prop models used in the Step Line street scene.
+
+The scene needs street furniture (bollards, benches, bins, planters, newspaper
+boxes, a hydrant) that reads as solid geometry instead of flat boxes. This tool
+keeps that art direction in one place:
+
+  * every prop is described as a small list of boxes and cylinders, so the
+    build is deterministic and runs offline in CI;
+  * an optional AI concept image per prop (OpenRouter, the same backend as
+    `generate_textures.py`) supplies the colour palette, so a model can look
+    like the concept without a 3D-model API;
+  * `build` writes standard glTF binary (`.glb`) files that Godot 4 imports as
+    `PackedScene`s, and `audit` checks the files are structurally valid.
+
+Commands (run from the repo root):
+
+  python3 tools/model_pipeline.py list
+  python3 tools/model_pipeline.py build
+  python3 tools/model_pipeline.py audit
+  python3 tools/model_pipeline.py concept            # needs OPENROUTER_API_KEY
+  python3 tools/model_pipeline.py concept --only bench
+
+The concept step is optional: `build` never needs the network. If
+`assets/models/concepts/<prop>.png` exists, its dominant colours replace the
+role colours from the catalogue, which is the only AI influence on the mesh.
