## Findings by Severity

No findings.

### Critical

* None.

### High

* None.

### Medium

* None.

### Low

* None.

## Assumptions and Deliberate Non-Fixes

* Legacy `isKernelSentinelEntity()` and `selectKernelSentinelFrame()` wrappers were left in place because the implementation notes identify them as compatibility wrappers and the session objective is to preserve existing Kernel Sentinel behavior while migrating consumers.
* Exported boss contract helpers with no current in-repo callers were left in place because the session spec calls for a reusable boss/finale contract surface and local lint/type settings do not treat exported helper availability as dead code.

## Behavior Changes

* Final-defense presentation now follows authored finale metadata instead of a raw depth/objective gate. Reviewed as intentional and spec-aligned: depth 3 objective floors no longer project final-defense markers by default, while depth 4 authored finale and explicit finale/win evidence still do.

## Verification

* Tests: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/boss-presentation.test.ts src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts src/extensions/ai-rogue/runtime/__tests__/audio.test.ts src/extensions/ai-rogue/runtime/__tests__/combat.test.ts src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts` - PASS - 6 files, 93 tests.
* Tests: `bun run test` - PASS - 409 files, 4655 tests.
* Browser smoke: `PLAYWRIGHT_REUSE_EXISTING_SERVER=true bunx playwright test tests/e2e/ai-rogue-runtime.spec.ts` - PASS - 16 tests.
* Linter: `bun run lint` - PASS.
* Formatter: `bunx prettier --check [reviewed files]` - PASS.
* Type checker: `bun run typecheck` - PASS.
* Script type checker: `bun run typecheck:scripts` - PASS.
* Whitespace: `git diff --check HEAD` - PASS.
* ASCII: `rg -n --pcre2 '[^\x00-\x7F]' [reviewed files]` - PASS - no matches.
* LF: `rg -n $'\r' [reviewed files]` - PASS - no matches.
* Final diff re-read: no remaining issues.

## Summary

1. Reviewed 19 files across spec artifacts, boss/finale runtime contracts, render/audio/combat/content consumers, and focused tests.
2. Findings: 0 critical, 0 high, 0 medium, 0 low; no repairs were required.
3. Deliberately left compatibility wrappers and exported boss contract helpers in place with evidence-backed rationale.
4. Verification passed for focused tests, full tests, lint, formatter, app typecheck, script typecheck, browser smoke, whitespace, ASCII, and LF checks.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/phase39-session06-boss-and-finale-contracts/code-review.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.
