# Sprint 38: Depth — Client Tasks

**Goal:** Map the generation pipeline from planetary heightmaps to walkable tile environments, formally park character/apartment work behind the full cascade, and close test/infra debt from Sprint 37.

**Branch:** `sprint-38/client`
**Agents:** Stig (dev), Tyre (arch), Hoshe (QA)

## Key Decisions

- `decisions/architecture.md` — D-169 (implant UI components), D-170 (HUD visibility)
- Implant component library: `client/ui/implant/` (ImplantPanel, ImplantHeader, etc.)
- HUD layer manager: `client/scripts/autoloads/hud_groups.gd`

## Notes

**#898 — Free camera viewer (bare minimum, throwaway)**
- The rendering system is up in the air — this viewer is iterative/disposable. Do not over-engineer.
- Current camera is locked to `GameState.player_position` (`client/scripts/autoloads/game_state.gd:18`).
- Decouple: add a debug/observer mode where camera position is independent of player entity.
- Controls: WASD/arrow key pan, scroll-to-zoom. That's it.
- The observer needs access to: implants (D-169/D-170 UI system), atlas, and map. Wire up existing `HudGroups` app paths (`implant/map`, `implant/wiki/gttr`, etc.).
- No player entity needed. No server-side observer entity. Just a free camera over whatever tile data exists.
- Key files: `client/main.gd` (camera setup), `client/scripts/autoloads/game_state.gd` (player_position), `client/scripts/autoloads/hud_groups.gd` (implant app switching).

**#882 — Strip archetype client code**
- Follow-up to server #878 (done). `CharacterArchetype` trace is Phase 6 filler.
- Find all client references to archetype enums/types and remove them.
- #878 already removed the server side — client should have no remaining consumers.

**#879 — Revive fog state behavioral tests**
- `test_fog_sprint22.gd` was deleted in Sprint 37 (#870 parse-error cleanup).
- Contained unique behavioral tests: `EXP_EXPLORED` persistence after leaving LOS, grow-only bounds invariant.
- Rewrite against current `FogState` API. Prefer live Gauntlet testing over mocks per testing preferences.

**#867 — dialogue_box confrontation signal bug**
- `signal_fired` remains false after `_on_option_pressed(0)` on a confrontation option.
- `_start_confrontation_beat` likely not firing in headless test mode.
- Check signal wiring in `client/ui/dialogue_box.gd`.

**#871 — Pre-existing test failures umbrella triage**
- 13 suites affected. For each: investigate, determine if it's stale assertion or real regression, then either fix inline or create a child ticket.
- Per feedback rules: broken tests need a fix or a dated ticket, never a shrug.

## Dependency Chain

```
#898 (free camera viewer) → standalone, start immediately
#882 (strip archetype code) → standalone (#878 done)
#879 (fog tests) → standalone
#867 (signal bug) → standalone
#871 (test triage) → standalone, spawns child tickets
```
