Subject: [PATCH] =?UTF-8?q?feat(assets):=20implant=20HUD=20icon=20set=20v0?=
 =?UTF-8?q?.1=20=E2=80=94=20#795?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

13 SVG icons covering stance indicators (walk/careful/sprint/crouch),
status badges (health, perception), interaction prompts (talk/observe/
follow/examine), and inventory silhouettes (manifest, access token,
comm log).

All D-086 compliant: 1px stroke, #c8d0e0 chrome, round linecaps,
minimal anchor points, no icon fonts, runtime-replaceable via
ShaderMaterial. Sizes: 20×20 (stance/status), 16×16 (actions),
40×40 (inventory). Unblocks client #787.

+title: "Implant HUD Icon Set — v0.1"
+description: "Design specification for the implant HUD icon vocabulary: stance indicators, status badges, interaction prompts, and inventory item silhouettes"
+type: design
+status: active
+ticket: "#795"
+decision_refs: [D-086]
+author: "Araminta"
+created: 2026-04-05
+updated: 2026-04-05

+
+# Implant HUD Icon Set — v0.1
+
+**Ticket:** #795
+**Author:** Araminta (Visual Designer)
+**Date:** 2026-04-05
+**Status:** Active — unblocks #787 (minimap + stance label implant conversion)
+**Decision reference:** D-086 (insert icon system)
+
+---
+
+## 1. Authoring Constraints (D-086)
+
+All icons in this set follow D-086 authoring constraints without exception:
+
+| Constraint | Value |
+|------------|-------|
+| Format | Custom SVG (no icon font) |
+| Stroke weight | `1px` base (scaled to `2px` for `lattice_augmented` via shader parameter) |
+| Chrome color | `#c8d0e0` (design reference — runtime-replaceable via ShaderMaterial) |
+| Anchor points | Minimal — prefer `L` (lines), `polyline`, `polygon`, `rect`, `circle`. Avoid `Q`/`C` curves. |
+| Fill | `none` on all paths except explicit solid elements (battery terminal caps, etc.) |
+| Terminations | `stroke-linecap="round"`, `stroke-linejoin="round"` — clean joins, not decorative |
+| Calibration | Icons must read cleanly at their target display size. Reference: Phosphor Light (MIT) — not for use, as legibility benchmark only |
+| Godot import | SVGs import via AtlasTexture. Runtime color swap via ShaderMaterial — do not bake color into shape variants |
+
+---
+
+## 2. Icon Inventory
+
+### 2.1 Stance Indicators
+
+**Location:** `client/assets/icons/`
+**Size:** 20×20px viewBox
+**Used in:** Insert HUD lower-left stance indicator, implant component library
+
+These icons appear alongside the text label (`WALK`, `CAREFUL`, etc.) per the insert HUD wireframe. They reinforce the label visually and support conversion to icon-first display in #787.
+
+| File | Stance | Design differentiator |
+|------|--------|-----------------------|
+| `icon_stance_walk.svg` | WALK | Upright figure, bilateral stride. Arms in natural walk swing (forward/back asymmetry). |
+| `icon_stance_careful.svg` | CAREFUL | Upright figure, arms spread laterally (environmental check posture). Legs closer together (deliberate foot placement). |
+| `icon_stance_sprint.svg` | SPRINT | Head and torso shifted forward (lean). Arms in pump position. Wide asymmetric leg stride. |
+| `icon_stance_crouch.svg` | CROUCH | Head lowered. Torso bent at waist. Knees bent via polyline angles. Compressed vertical range. |
+
+**Recognition at 20px:** Stance icons are always displayed with the text label in v0.1. The icons reinforce the text; they do not replace it. Pattern recognition builds over ~10 minutes of play (same threshold as the radial menu, D-058).
+
+### 2.2 Status Badges
+
+**Location:** `client/assets/icons/`
+**Size:** 20×20px viewBox
+**Used in:** Insert HUD chrome band (top row), perception mode indicator
+
+| File | Badge | Design |
+|------|-------|--------|
+| `icon_status_health.svg` | HEALTH | Medical cross — two overlapping rects forming a plus symbol. Geometric, no curves. |
+| `icon_status_perception.svg` | PERCEPTION MODE | Diamond eye — four-sided polygon outline with centered circle pupil. Diamond shape reinforces insert lattice aesthetic. |
+
+**Perception mode variants:** Mode-specific icons (thermal, camera feed, etc.) are deferred until #315 fully specs the perception modes. The `icon_status_perception.svg` is a generic "perception layer active" indicator only.
+
+### 2.3 Interaction Prompt Icons
+
+**Location:** `client/assets/icons/`
+**Size:** 16×16px viewBox
+**Used in:** Entity hover interaction verb display (insert layer, z-6)
+
+These appear when the cursor enters an entity's interaction radius. They supplement the verb text (e.g., `Talk`). Per the HUD wireframe, the verb text is primary — icons are secondary affordance.
+
+| File | Action | Design |
+|------|--------|--------|
+| `icon_action_talk.svg` | TALK | Speech bubble — rectangular body, triangle callout at bottom-left, two content lines. |
+| `icon_action_observe.svg` | OBSERVE | Diamond eye (shares vocabulary with `icon_status_perception.svg`). |
+| `icon_action_follow.svg` | FOLLOW | Arrow right — shaft and arrowhead. Directional / movement. |
+| `icon_action_examine.svg` | EXAMINE | Magnifying glass — lens circle with diagonal handle. The circle is a geometric primitive. |
+
+**Extending verb coverage:** Additional verbs (`Confront`, `Wait`, etc.) will need icons as the verb list expands. Follow the diamond-eye vocabulary for perception verbs; arrow vocabulary for movement; speech bubble vocabulary for social verbs.
+
+### 2.4 Inventory Item Silhouettes
+
+**Location:** `client/assets/icons/`
+**Size:** 40×40px viewBox
+**Used in:** Insert HUD inventory band (lower-right, per insert-hud-wireframe-v01.md §7)
+
+D-086 amendment (2026-04-05): inventory icons are no longer character-specific. [D-117] eliminated the smuggler/detective frame; [D-122] removed named characters. These icons apply to any character who can carry physical items.
+
+| File | Item | Design |
+|------|------|--------|
+| `icon_item_manifest.svg` | Manifest (document) | Pentagon-body document with folded top-right corner. Three text-content lines inside. |
+| `icon_item_access_token.svg` | Access token (hex tag) | Flat-top hexagon with punch-hole circle near top. Two interior encoding lines. |
+| `icon_item_comm_log.svg` | Personal comm log (device) | Rectangular handheld body with screen inset, antenna stub, signal lines (polylines), control button. |

+## 3. Visual Grammar Integration
+
+### 3.1 Color behavior
+
+The `#c8d0e0` chrome color is the design reference only. At runtime:
+- Default: `#c8d0e0` (insert chrome — unchanged)
+- `lattice_augmented` profile: stroke scales to 2px; color may shift to a brighter white
+- `insert_active == false`: icons reduce to 30–50% opacity (per element, per insert HUD wireframe §9.2)
+- Entity icons (if using D-033 relationship colors): color swapped via ShaderMaterial parameter
+
+Saturation rule (D-044): insert chrome must never compete with entity D-033 colors. Icons in `#c8d0e0` are intentionally de-saturated. Do not use warmer or more saturated colors in any icon variant.
+
+### 3.2 Godot import setup
+
+```gdscript
+# Load SVG as ImageTexture (Godot 4 native SVG import)
+# In .import settings: set scale to match display target size
+# Runtime color replacement:
+var icon_material = ShaderMaterial.new()
+icon_material.shader = preload("res://shaders/icon_tint.gdshader")
+icon_material.set_shader_parameter("tint_color", Color("#c8d0e0"))
+icon_node.material = icon_material
+```
+
+The `icon_tint.gdshader` (to be authored by client team) multiplies the SVG's existing stroke color by the `tint_color` parameter. Since all SVGs use `#c8d0e0` as their stroke, the default parameter leaves them unchanged; swapping the parameter recolors them at runtime.
+
+### 3.3 Sizing at non-native resolutions
+
+All icons have explicit `width` and `height` attributes matching their viewBox. Godot's SVG importer respects these. For 2x displays, import at 2x scale — do not stretch from 1x. The 1px stroke renders correctly at integer multiples.
+
+---
+
+## 4. What This Document Does Not Cover
+
+- **Perception mode variant icons** (thermal, camera, etc.) — awaiting #315 full spec
+- **Minimap POI icons** — the insert HUD uses geometric primitives (diamonds, dots, squares) rendered as primitives, not SVG imports (per insert-hud-wireframe-v01.md §4)
+- **Cursor state icons** — specified in D-056, cursor states are handled by the cursor rendering system
+- **World radial menu icons** — the four spokes (Observe, Insert, Comms, Wait) in D-058 need a follow-on ticket
+
+---
+
+## 5. Calibration Notes
+
+Test all icons at their native display size (20×20px or 16×16px) at 100% scale before approving implementation. The Phosphor Light benchmark:
+
+> *If a custom icon doesn't read as cleanly as a Phosphor Light equivalent at 16px, simplify it.*
+
+The stance icons are the most complex. If any stance icon reads poorly at 20px on a real display, simplify to fewer line segments. The text label remains available as the primary affordance.
+
+Inventory icons at 40×40 have more room and should read clearly without simplification.
