# Implementation Summary

**Session ID**: `phase35-session09-documentation-and-media-policy-sync` **Completed**: 2026-06-27 **Duration**: 1 hour

***

## Overview

Session 09 synced maintained AI Rogue documentation with the current Web Audio, media-policy, production default, browser-local state, and public-demo boundary contracts. The session did not change runtime code. It added clear supersession language around historical optional-audio, no-audio, old 200 KB all-assets, and opt-in enablement planning text so final release validation can use the docs baseline without ambiguity.

## Technical Decisions

1. **Preserve historical records**: Old Phase 30 docs were labeled and superseded instead of rewritten, keeping evidence intact while preventing stale claims from reading as current contracts.
2. **Document implemented behavior only**: Docs now describe mixing, fades, loops, one-shots, low-HP heartbeat, lazy decode, mute and volume preferences, browser-autoplay unlock, and silent fallback without claiming sidechain or event-based ducking.
3. **Keep media policy centralized**: AI Rogue docs point to the maintained media policy for the 200 KB non-logo/non-music cap and 900 KB AI Rogue music cap rather than duplicating divergent rules.

| Asset-size policy | PASS                             |
| Stale-claim scans | PASS                             |
| Security/GDPR     | Security PASS; GDPR N/A          |
| Coverage          | Not reported by invoked commands |

## Lessons Learned

1. Historical session docs need explicit supersession language when later behavior changes otherwise make old evidence look like current policy.
2. Documentation validation should include stale-claim scans alongside lint and format checks when old planning records are intentionally preserved.
3. Media-cap wording should keep music and non-music asset categories separate because enforcement differs by path.

***

## Future Considerations

Items for future sessions:

1. Session 10 should use this documentation baseline during the final release gate and rerun the full app, AI Rogue, Pages, privacy, budget, asset, and playthrough checks.
2. Future AI Rogue audio changes should update `game-feel.md`, `visual-assets.md`, `docs/media-policy.md`, and stale-claim scan classifications in the same session.

# 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/phase35-session09-documentation-and-media-policy-sync/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.
