# BRIEFING — 2026-10-02T05:26:00Z

## Mission
Investigate UI, layout, and visual requirements for the PC Desktop client (100vw/100vh, Grimdark action HUD, health/mana globes, central action bar, minimap, chat box, hover tooltips, modals, reactive i18n) and produce a detailed architectural specification for implementation.

## 🔒 My Identity
- Archetype: explorer
- Roles: survey, ui/layout investigation, synthesis
- Working directory: c:\Projects\FreeExile\.agents\teamwork\survey_explorer_2\
- Original parent: 7eb101bf-362e-46b0-81cc-0a9216617c39
- Milestone: PC Desktop Full-Screen Client UI/HUD Survey

## 🔒 Key Constraints
- Read-only investigation — do NOT implement
- Scope: UI, layout, and visual requirements for PC Desktop client (client/web_pc/) based on R1 & R3
- Zero mobile simulator elements (.iphone-frame, #simulator-bar, touch joystick)
- Fullscreen 100vw, 100vh responsive layout (16:9, 16:10, 21:9 Ultrawide)
- Reactive i18n 9 languages, zero hardcoded UI strings, no page reload
- Write handoff.md and communicate via send_message to parent

## Investigation State
- **Explored paths**:
  - `client/webapp/index.html` (mobile chassis, headers, simulator bar, HUD elements)
  - `client/webapp/css/main.css` (`.iphone-frame` fixed sizing, typography, CSS vars)
  - `client/webapp/css/hud_skills.css` (orbs styling, skill bar, cooldown overlays)
  - `client/webapp/js/engine/iso_math.js` (`resizeCanvas`, `worldToIso`, `isoToWorld` dynamic viewport sizing)
  - `client/webapp/js/ui/hud_orbs.js` (fluid wave dynamics, canvas 2D rendering, HP/Qi bindings)
  - `client/webapp/js/ui/skill_bar_controller.js` (cooldown sweeps, slot registration, key handling)
  - `client/webapp/js/ui/minimap_hud.js` (terrain baking, indicators, compass pointer)
  - `client/webapp/js/ui/chat_ui.js` (8 channels, minimized ticker, expanded log, item tooltips)
  - `client/webapp/js/ui/tooltips.js` (hover engine, positioning, clamping)
  - `client/webapp/templates/character_modal.html` & `bag_modal.html` (left/right docking layout)
  - `client/webapp/js/data/i18n.js` & `i18n_catalog.js` (reactive 9-language DOM updater)
- **Key findings**:
  - `iso_math.js` automatically drives canvas size and isometric camera centering from `viewport.clientWidth` and `viewport.clientHeight`. Fullscreen 100vw x 100vh works natively without engine code modifications.
  - Symmetrical Grimdark Action HUD for desktop: Bottom-left Health Globe, Bottom-right Mana Globe, Centered Action Bar (Flasks 1-5, Skills QWER, LMB/RMB, Spacebar Dodge, and EXP bar).
  - Side-by-side dual docking allows Character Sheet ('C') on the left and Inventory ('I') on the right to be opened simultaneously without obstructing the central 2.5D game view.
  - `FreeExileI18n.updateDOM()` provides instant in-place 9-language translation with zero page reload.
- **Unexplored areas**: None within the survey scope; input implementation and test runner execution will be handled by subsequent worker agents.

## Key Decisions Made
- Designed comprehensive `client/web_pc/index.html`, `pc_main.css`, `pc_hud.css`, and `pc_modals.css` specifications.
- Established strict 100vw/100vh viewport rules with zero `.iphone-frame` or touch joystick.
- Preserved shared engine module reusability from `../webapp/` without any risk of mobile regression.
