## Technical Decisions

1. **Presentation boundary only**: G5 visuals derive from existing snapshots, pending threats, combat log events, status effects, and audio metadata so boss footprint, pathing, collision, objective rules, win conditions, and persistence remain unchanged.
2. **Manifest-first asset flow**: Accepted and rejected G5 candidates are recorded in the crop manifest before atlas regeneration, keeping visual provenance reviewable.
3. **Typed frame contracts**: G5 frame names are expressed as TypeScript unions and required-frame constants so missing atlas output fails in tests.
4. **Bounded event windows**: Boss charge, attack, hit, shield, and shutdown presentation expires deterministically and falls back to idle.

## Test Results

| Metric             | Value                     |
| ------------------ | ------------------------- |
| Full Vitest files  | 386 passed                |
| Full Vitest tests  | 4429 passed               |
| Focused Vitest     | 5 files / 49 tests passed |
| Desktop Playwright | 13 passed                 |
| Mobile Playwright  | 6 passed                  |
| Coverage           | Not generated             |

Additional gates passed: visual packer, `bun run typecheck`, `bun run typecheck:scripts`, `bun run lint`, asset-size policy, targeted Prettier check for changed files, `git diff --check`, ASCII scan, and LF scan.

***

## Lessons Learned

1. Some generated G5 candidates needed rejection because they became ambiguous or text-like at runtime scale.
2. Keeping final-defense markers in the gameplay atlas avoided unnecessary UI atlas ownership changes.
3. Shared presentation helpers kept render-model, HUD, effects, and tests from duplicating event-to-frame rules.

***

## Future Considerations

Items for future sessions:

1. Session 04 should apply the same manifest-first review discipline to G3 sector theme decals and avoid changing world-generation rules.
2. Session 06 should treat G7 player animation as direct runtime art only if 16x16 downscale readability is proven.
3. Existing repo-wide `format:check` still reports prior-session committed spec artifacts outside this session's review surface.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase37-session03-g5-boss-presentation/implementation_summary.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
