# Implementation Summary

**Session ID**: `phase24-session08-generated-asset-implementation-handoff` **Package**: apps/web **Completed**: 2026-07-08 **Duration**: 1 hour

***

## Overview

Session 08 promoted the Phase 3 generated visual sheets from manifest-only evidence into typed `apps/web` implementation references. The work added a source-owned generated asset map, blocked app media catalog records, fallback labels, reduced-motion static posture, battlefield layer metadata, focused tests, and docs while preserving the no-runtime-loading boundary for `assets/generated/game-design/`.

## Technical Decisions

1. **Typed references before runtime serving**: Generated sheets are pinned in app source and catalog records, but browser runtime code still does not load from `assets/generated/game-design/`.
2. **Fallback posture as a contract**: Every Phase 24 visual state now resolves to a generated asset id or explicit typed fallback label, which tests can assert without adding debug UI.
3. **Blocked media catalog records**: The app catalog records the sheets as implementation references with explicit release blockers until app-owned serving, slicing, optimization, and media gates exist.

## Test Results

| Metric                | Value                  |
| --------------------- | ---------------------- |
| Focused Session Tests | 101 passed / 101       |
| Web Project Tests     | 2314 passed / 2314     |
| Root Tests            | 3395 passed, 1 skipped |
| Failed                | 0                      |
| Coverage              | Not collected          |

***

## Lessons Learned

1. Typed generated-asset posture can make design handoff auditable without forcing source-art paths into runtime UI.
2. Data attributes plus focused tests are enough to prove visual-state coverage while keeping product-facing battlefield copy clean.

***

## Future Considerations

Items for future sessions:

1. Session 09 should use the generated asset map and media catalog records as phase-exit evidence for reduced-motion parity and Fun Law 1 documentation.
2. Future art-serving work should promote assets through app-owned runtime paths and media gates before any browser image loading is introduced.

# 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://faction-os.gitbook.io/faction-os-docs/.spec_system/specs/phase24-session08-generated-asset-implementation-handoff/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.
