# Implementation Summary

**Session ID**: `phase36-session01-current-audio-balance-audit` **Completed**: 2026-06-28 **Duration**: 2-3 hours

***

## Overview

Session 01 validated the current AI Rogue audio baseline before later Phase 36 asset work. It recorded desktop and mobile browser-path evidence for unlock, title queueing, run-start SFX, sector music, runtime-control confirmations, Settings mute and volume persistence, no-Web-Audio fallback, repeated combat, deterministic cue scenarios, and asset policy. No runtime code or media assets were added.

## Technical Decisions

1. **No new audio assets**: The session stayed an evidence and documentation pass so downstream asset generation can consume validated follow-ups.
2. **Objective evidence with acoustic caveat**: Browser instrumentation and volume scans prove playback paths and outliers, while Session 08 still owns final human acoustic listening.
3. **Follow-up ownership stays explicit**: Enemy-family metadata, family/boss SFX, theme audio, adaptive stingers, quiet milestone cues, and wall-bump fatigue are routed to later Phase 36 sessions.
4. **Phase 37 planning remains separate**: Visual asset PRD/stub files are preserved, but state stays on Phase 36 because audio finishing is still in progress.

| Focused audio tests   | 9 passed      |
| Desktop Playwright    | 9 passed      |
| Mobile Playwright     | 5 passed      |
| Asset policy          | PASS          |
| Lint/typecheck/format | PASS          |
| Coverage              | Not collected |

## Lessons Learned

1. Browser-path evidence can prove audio unlock, routing, persistence, and fallback behavior, but final mix judgment still needs human acoustic review.
2. Objective volume scans are useful for ranking likely fatigue and quiet-cue risks before generating replacement assets.
3. Phase handoffs should name cue IDs, runtime touchpoints, severity, and owner sessions so later asset work does not re-audit the same baseline.

***

## Future Considerations

Items for future sessions:

1. Session 02/03 should add typed enemy-family audio metadata before generating family and boss cue identities.
2. Session 03 or Session 08 should decide whether to reduce or regenerate `45_wall_bump_variant_a.ogg` and lift quiet milestone cues after human listening.
3. Session 04/05 should keep music depth-based until a theme-aware audio routing contract and selected sector assets exist.
4. Session 06/07 should keep adaptive stingers conditional until the engine contract defines any second bus, ducking, or transient gain behavior.

# 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-session01-current-audio-balance-audit/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.
