# Code Review and Repair Report

**Session ID**: `phase36-session06-adaptive-music-engine-expansion` **Reviewed**: 2026-06-28 **Scope**: All uncommitted changes in the working tree **Result**: RESOLVED

## Review Surface

**Files reviewed** (all uncommitted changes):

* `.spec_system/PRD/phase_36/session_06_adaptive_music_engine_expansion.md` - tracked-modified
* `.spec_system/state.json` - tracked-modified
* `docs/extensions/ai-rogue/README.md` - tracked-modified
* `docs/extensions/ai-rogue/game-feel.md` - tracked-modified
* `src/extensions/ai-rogue/runtime/__tests__/audio.test.ts` - tracked-modified
* `src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts` - tracked-modified
* `src/extensions/ai-rogue/runtime/audio.ts` - tracked-modified
* `src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts` - tracked-modified

**Inventory commands**: `git status`, `git diff HEAD`, `git diff --cached`, `git ls-files --others --exclude-standard`

## Findings by Severity

### Critical

* No findings.

### High

* No findings.

### Medium

* `src/extensions/ai-rogue/runtime/renderer-audio-adapter.ts:142` - Terminal adaptive requests treated missing `previousSnapshot` context as a status transition because `previousSnapshot?.status !== "won"` and `!== "lost"` evaluate true when the snapshot is absent. That could emit victory or defeat adaptive ducking from adapter calls without before/after context, contrary to the transition-only contract. | Fix: required `previousSnapshot` before routing `victory_transition` or `defeat_transition`, updated terminal transition tests to pass active previous snapshots, and added a no-previous-snapshot regression test. | Status: FIXED

### Low

* No findings.

## Assumptions and Deliberate Non-Fixes

* Full `bun run format:check` reports pre-existing formatting warnings in `.spec_system/CONSIDERATIONS.md`, `.spec_system/SECURITY-COMPLIANCE.md`, and `.spec_system/specs/phase36-session01-current-audio-balance-audit/spec.md`. `git status --short` and `git diff --name-only HEAD --` for those paths produced no output, so they are unchanged and outside this review scope. I left them untouched and verified formatting for every uncommitted text file directly.

## Behavior Changes

* Terminal adaptive transition requests now require previous snapshot context. Victory and defeat music still route without previous context, but adaptive victory/defeat ducking does not fire unless the adapter can prove an active-to-terminal transition.

## Verification

* Tests: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/audio.test.ts src/extensions/ai-rogue/runtime/__tests__/renderer-audio-adapter.test.ts` - PASS - 2 files, 35 tests
* Tests: `bunx vitest run src/extensions/ai-rogue/runtime/__tests__/combat.test.ts src/extensions/ai-rogue/runtime/__tests__/protocols.test.ts src/extensions/ai-rogue/runtime/__tests__/compile.test.ts src/extensions/ai-rogue/runtime/__tests__/objective-lock.test.ts` - PASS - 4 files, 26 tests
* Tests: `bunx playwright test tests/e2e/ai-rogue-runtime.spec.ts -g "AI Rogue browser audio pack fetches enemy, boss, and theme audio"` - PASS - 2 Chromium tests
* Linter: `bun run lint` - PASS
* Formatter: `bun run format:check` - FAIL - pre-existing unchanged Markdown warnings outside uncommitted scope, listed above
* Formatter: `bunx prettier --check [all uncommitted text files]` - PASS
* Formatter: `git diff --check HEAD` - PASS
* Type checker: `bun run typecheck` - PASS
* Type checker: `bun run typecheck:scripts` - PASS
* Asset sizes: `bash scripts/check-asset-sizes.sh` - PASS - total 15M
* Encoding: targeted ASCII and CRLF scans over all uncommitted text files - PASS
* Final diff re-read: no remaining issues found

## Summary

1. Reviewed 14 final uncommitted files covering the adaptive audio engine, renderer adapter, tests, browser proof, docs, state, and session artifacts.
2. Findings: 0 critical, 0 high, 1 medium, 0 low; the medium finding was repaired with code and regression coverage.
3. Deliberately did not fix pre-existing formatting warnings in unchanged files outside the uncommitted review surface.
4. Verification passed for focused unit tests, simulation-side tests, browser proof, lint, type checks, targeted formatting, diff whitespace, asset sizes, and encoding.

# 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/phase36-session06-adaptive-music-engine-expansion/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.
