Summary

Checkpoint of local main work, moved onto emberwatch-fixes so it can be reviewed as a PR into main.

main was reset to origin/main (b1fce9096); this branch carries the previously-unpushed history (Update vite.config.ts) plus one checkpoint commit with all working-tree changes.

Contents

  • dev/combat: battlefield projection + diagnostics, health, canvas viewport, live session, and view-model types; new combat_debug_live visual suite
  • engine: debug scene overlay/controller, heartbeat reporter, world resize, index barrel, input controller updates
  • game UI: HUD layout editor overlay + view model, game HUD surface, UI composition/view-model types
  • audio: music player service/composition/overlay, settings audio wiring, dev audio view model
  • e2e: combat_debug + hud_customization POMs/specs and tests
  • client config: vite.config.ts
  • docs / ops: combat debug workspace guide, customizing-your-HUD guide, guard cognitive-complexity baseline, scripts/.env.example
  • secrets: re-encrypted secrets/production.enc.env and secrets/staging.enc.env (sops)

Notes

  • Pre-commit formatting + typecheck passed for the affected projects; CI will confirm the full sweep.
  • The encrypted env files are included because the working-tree changes touched them — please verify before merging.

Summary by CodeRabbit

  • New Features

    • Added battlefield visualization, camera fitting, overlay toggles, pointer details, and health diagnostics to Combat Debug.
    • Added support for synthetic and authored battlefield scenarios with render-parity checks.
    • Added drag-and-drop HUD widget placement from the editor list and preview.
    • Added per-widget visibility controls, including contextual music-player visibility.
  • Bug Fixes

    • Fixed player health bars rendering with no visible fill.
    • Improved embedded canvas sizing during layout and browser resizing.

Merge Risk: 🔵 Low · up to 4d642

These changes add combat debugging tools and HUD editor improvements. The remaining issues are architecture-rule violations in two views and a schema's placement, plus minor diagnostic and test-reliability gaps in developer tooling. These are low risk and should be addressed by the owner, but they do not block normal gameplay.

Inline comments:
In `@apps/e2e/src/visual/suites/combat_debug_live.visual.ts`:
- Around line 116-125: Update the readiness wait in the visual combat test to
poll the battlefield status until it is exactly “Ready” after confirming the
authored scenario. Detect the engine’s error state during polling and fail
immediately with its error details, then remove the fixed 1.5-second delay.
- Around line 19-34: Move the BattlefieldSchema definition out of the apps/e2e
visual suite into an allowed shared package, export it there, and import and
reuse it in combat_debug_live.visual.ts without changing its fields or
validation behavior.

In `@apps/frontend/client/src/lib/services/export/export_service.test.ts`:
- Around line 62-64: Strengthen the deleteAllLocalData test by keeping
mockDb.transaction pending until explicitly released, waiting for transaction
start, and asserting mockFlush has not been called. Release the transaction,
await deletion, and verify flushing occurs only after transaction settlement;
remove the invocationCallOrder assertion.

In `@apps/frontend/client/src/lib/views/dev/combat/combat_debug_view.svelte`:
- Around line 230-232: Move the untrack lifecycle wrapper from the view into the
ViewModel: add a ViewModel method that invokes initializeLiveCanvas within
untrack, then update the attachment callback to delegate through viewModel using
only property access and method invocation.

In
`@apps/frontend/client/src/lib/views/game/ui/hud/hud_layout_editor_overlay.svelte`:
- Around line 36-42: Move anchorAtPoint, onPointerDown, onDragPointerUp,
onDragPointerMove, and the onkeydown focus-policy logic out of the Svelte view
into a dedicated interaction adapter or controller. Update the template so it
only reads viewModel properties and uses arrow-wrapper handlers that delegate to
ViewModel methods, preserving the existing pointer, drag, anchor lookup, and
keyboard behavior.

In `@packages/frontend/engine/src/game_world/debug_scene_controller.ts`:
- Line 126: Update getDiagnostics() to prefer the fitted camera stored in
_camera, falling back to _accessors.getCamera() when no fitted camera exists, so
diagnostics immediately after setScene() report the current camera.

In `@packages/frontend/engine/src/game_world/debug_scene_overlay.ts`:
- Around line 140-145: Update the actor label logic to check actor.defeated
before actor.downed, so actors in both states return the terminal “defeated”
label while exclusively downed actors still return the downed label.

Wait for the authored world to become ready.

The battlefield summary changes to authored immediately after scenario selection. It does not prove that the content pack or map finished loading. The fixed 1.5-second delay can capture the loading surface or a blank canvas on slower systems.

Wait for the status to become Ready and fail immediately if the engine reports an error.

Assert transaction completion before flushing.

This test runs with Bun 1.4.0. Bun exposes mock.invocationCallOrder, so the assertion does not throw for that reason. However, it records invocation order, not promise settlement. If deleteAllLocalData calls flush without awaiting transaction, this assertion still passes. Keep the transaction pending, assert that mockFlush has not run, resolve the transaction, then await deletion and assert the flush call.

Move untrack into the ViewModel boundary.

The attachment now performs lifecycle control in the Svelte view. Add a ViewModel method that wraps initializeLiveCanvas() in untrack, then let the attachment delegate to that method.

As per coding guidelines, “Zero logic — only property access on viewModel.” As per path instructions, “Views stay logicless — logic belongs in the ViewModel.”

Move interaction logic out of the Svelte view.

anchorAtPoint, onPointerDown, onDragPointerUp, and onDragPointerMove put DOM lookup, gesture policy, and drag-state decisions in the view. The onkeydown callback also implements focus policy in the view.

Move this behavior to a dedicated interaction adapter or controller. Keep this template limited to viewModel property reads and arrow wrappers that call a ViewModel method.

As per coding guidelines, Svelte views require “Zero logic — only property access on viewModel” and “Event handlers use arrow wrappers.”

Report the fitted camera in diagnostics.

_fit() writes the new camera to _camera, but getDiagnostics() reads the previous GameWorld camera. Callers read diagnostics immediately after setScene(), before the ticker copies _camera into GameWorld. The camera summary can remain stale until another resize.

Use the fitted camera when it exists.

Proposed fix

+    const camera = this._camera ?? this._accessors.getCamera();

Prioritize the defeated state in token labels.

If an actor is both downed and defeated, this function returns "(downed)". The token color and opacity still show the actor as defeated. Check defeated first so the diagnostic label reports the terminal state.
