## 4. Technical Specifications & Compliance Rules

1. **Power-of-Two Dimensions ($2^n$)**:
   - All 55 PNG image files MUST strictly adhere to $2^n$ dimensions along both axes ($128, 256, 512, 1024$).
   - Valid rectangular aspect ratios include $1024\times 512$, $512\times 256$, $256\times 512$, and $256\times 128$.
2. **Tangent-Space Sobel Normal Maps**:
   - Exactly 6 DRQs mandate normal maps: `DRQ 06` (Crafting Orbs), `DRQ 07` (Bloodstones), `DRQ 13` (Security Shield), `DRQ 19` (Hideout Props), `DRQ 20` (Map Device & Arena), `DRQ 21` (Passive Tree Nodes).
   - Strict mathematical validation rule: Blue channel mean $\ge 128$ ($Z$-vector pointing outward from surface normal).
3. **Emissive Core Masks**:
   - Dedicated deliverable files: `bloodstones_atlas_emissive.png` (DRQ 07) and `passive_node_atlas_emissive.png` (DRQ 21).
   - Core emissive specs defined for: Crafting Orbs (DRQ 06), Security Shield (DRQ 13), and Astral Map Device (DRQ 20).
4. **Apple Metal Shaders (`.metal`)**:
   - 3 Apple Metal shaders required for ProMotion 120Hz ($8.33\text{ ms/frame}$ budget):
     * `loot_beam_shader.metal` (DRQ 08) — Vertical light column oscillations & beam flares.
     * `shield_pulse.metal` (DRQ 13) — Hardware App Attest biometric rim glow & pulse distortion.
     * `agent_orb_beam.metal` (DRQ 15) — Totemic soul pillar vortex & rune illumination.
5. **Atlas Metadata JSON**:
   - 20 of 21 DRQs require structured JSON metadata defining frame coordinates `[x, y, w, h]`, 9-slice borders, anchors, and animation frame sequences. Only `DRQ 09` (Cutscene Splash Art) is exempt.
6. **Size Budget Constraints**:
   - UI elements, HUD atlases, VFX: `< 150KB` (or `< 50KB` for telemetry/forensics/props).
   - Full-bleed illustrations, high-res splash art, character standees, boss arena tilesets: `< 2MB`.

## Edge Cases

| # | Feature | Input | Observed Behavior |
|---|---------|-------|-------------------|
| 1 | Dimension Verification | Non-power-of-two image (e.g. $1000\times 500$ or $1920\times 1080$) | `qa_technical_audit()` logs error: `File {name} dimensions ({w}x{h}) are not power of 2.` and sets verdict to `FAIL`. |
| 2 | Normal Map Blue Mean | Inverted or non-tangent normal map (e.g. object-space or flat grey, Blue mean = 100) | Violates engineering standard `Blue channel mean >= 128`, causing incorrect PBR lighting and shadow inversion under dynamic shaders. |
| 3 | Asset Size Budget | File size exceeding budget (e.g. `virtual_joystick_atlas.png` at 350KB, budget < 150KB) | `qa_technical_audit()` flags violation: `File {name} size ({size_kb}KB) exceeds limit of {max_file_size_kb}KB.` and rejects to `rejected/`. |
| 4 | Missing Atlas Metadata | DRQ lacking metadata JSON when deliverables require it | Pipeline tools and WebApp spritesheet unpacker fail to resolve tile offsets, leading to missing textures or blank UI slots. |
| 5 | Storyboard Metadata Absence | `DRQ-20261001-NPC-CUTSCENE-STORYBOARD` has 4 PNGs but no JSON deliverable | Normal for full-bleed story splash screens; asset pipeline must tolerate standalone concept illustrations without requiring metadata JSON. |
| 6 | Emissive Mask Nomenclature | DRQs with emissive requirements in specs vs explicit deliverables | DRQ 07 and DRQ 21 explicitly require separate `*_emissive.png` files; DRQ 06, 13, 20 describe emissive core properties in specs that can be embedded in alpha channel or separate mask. |
| 7 | Metal Shader Compilation | iOS Metal shader (`.metal`) deployed on non-Apple environments (Web/Windows) | WebApp client requires fallback GLSL/WebGL shader or CSS animation fallback when running outside iOS native Metal runtime. |
| 8 | Subagent Roster Mapping | 21 DRQs assigned to 4 distinct subagents (`mobile_ui_designer`: 10, `concept_artist`: 4, `isometric_animator`: 4, `vfx_tech_artist`: 3) | Dispatcher must route generation and reviews to specialized domain agents per the Autonomous Game Studio directives. |

## 5-Component Handoff Report

### 1. Observation
- Verified all 21 markdown files in `docs/design_requests/inbox/`. Every file contains valid metadata (ID, title, requesting department, priority, category, subagent, dimensions, size budget, normal map flag, deliverables list, and two-stage approval gate).
- Total file count in inbox: exactly 21 files.
- Deliverables count across all 21 files: exactly 78 items (55 PNGs, 3 Metal shaders, 20 JSON metadata files).
- Normal maps explicitly required in 6 files (`DRQ 06, 07, 13, 19, 20, 21`).
- Metal shaders required in 3 files (`DRQ 08, 13, 15`).
- Emissive masks required as explicit deliverable in 2 files (`DRQ 07, 21`) and specified in technical specs in 3 additional files (`DRQ 06, 13, 20`).
- Pipeline status command `python -m tools.asset_pipeline.design_pipeline_cli report` confirmed 21 inbox, 0 in progress, 0 pending, 18 approved.

### 2. Logic Chain
1. *Premise*: Acceptance criteria R1, R2, R3 in `ORIGINAL_REQUEST.md` (2026-10-02T06:36:44Z) demand full delivery, tech-art validation, two-stage approval, and client synchronization for all 21 inbox DRQs.
2. *Premise*: Each DRQ specifies exact deliverables in Section 4 and technical constraints in Sections 1 & 3.
3. *Inference*: To achieve zero-defect implementation, downstream worker subagents (`concept_artist`, `mobile_ui_designer`, `isometric_animator`, `vfx_tech_artist`) must generate precisely the 78 deliverables meeting power-of-2 dimensions ($2^n$), size budgets (< 50KB, < 150KB, < 2MB), and PBR normal map standards (Blue $\ge 128$).
4. *Inference*: The 20 JSON metadata files and 3 Metal shaders must accompany the images to pass Stage 1 QA Technical Audit and enable automated synchronization into `client/webapp/assets/`.

### 3. Caveats
- No assets have been generated yet in `assets/pending_review/` (spec miner is read-only).
- Three DRQs (`DRQ 06`, `DRQ 13`, `DRQ 20`) mention emissive core masks in the technical specifications table, but their Section 4 deliverables lists do not separate the emissive mask into a standalone file name (unlike DRQ 07 and DRQ 21). Workers should follow Section 4 deliverables or provide combined RGBA packing as appropriate.

### 4. Conclusion
- Complete, unambiguous specification survey for all 21 DRQs completed.
- Full inventory of 78 deliverables, power-of-2 dimensions, normal map requirements, emissive requirements, Metal shaders, atlas metadata, and size budgets cataloged and verified.
- The pipeline is primed for immediate dispatch to specialized design subagents.

### 5. Verification Method
- Run `python -m tools.asset_pipeline.design_pipeline_cli report` to verify the 21 inbox DRQs.
- Inspect `c:\Projects\FreeExile\.agents\teamwork\spec_miner_survey_1\survey_summary.json` for machine-readable JSON structure of all 21 DRQs.
- Invalidation conditions: If any deliverable in the 21 DRQs changes filename, dimensions, or path, this survey must be updated.
