**Notes**:

* Resolved missing local `.spec_system/scripts/` by reading `.spec_system/state.json` directly and using the active session metadata.
* Confirmed the repository `.nvmrc` pins Node 26.2.0 and `nvm use 26.2.0` satisfies the convention baseline.
* Confirmed the Phase 3 generated sheets already exist and the manifest records the same ids, paths, dimensions, and runtime posture.
* Inspected the existing app media catalog and helper/query pattern before adding records.

**Files Changed**:

* `.spec_system/specs/phase24-session08-generated-asset-implementation-handoff/implementation-notes.md` - created implementation evidence log.

* Validated changed and untracked text outputs for ASCII-only content and LF line endings.
* Captured generated Phase 3 PNG evidence for the three implementation-reference assets used by the typed map, docs, and media catalog records.
* Confirmed the git whitespace check is clean.

**Files Changed**:

* `.spec_system/specs/phase24-session08-generated-asset-implementation-handoff/implementation-notes.md` - added final validation and generated asset evidence.
* `.spec_system/specs/phase24-session08-generated-asset-implementation-handoff/tasks.md` - marked final task and completion checklist.

**Generated Asset Evidence**:

* `assets/generated/game-design/phase03/live-enemies/live-enemy-effects-sheet.png` - 2309067 bytes, PNG image data, 1672 x 941, 8-bit/color RGB, non-interlaced.
* `assets/generated/game-design/phase03/strike-vocabulary/strike-vocabulary-effects-sheet.png` - 2326219 bytes, PNG image data, 1672 x 941, 8-bit/color RGB, non-interlaced.
* `assets/generated/game-design/phase03/reduced-motion/reduced-motion-static-badges-sheet.png` - 2459464 bytes, PNG image data, 1672 x 941, 8-bit/color RGB, non-interlaced.

**Verification**:

* Command/check: `git diff --check`
  * Result: PASS - no whitespace errors reported.
  * Evidence: command completed with exit code 0.
* Command/check: changed/untracked text ASCII and CRLF scan
  * Result: PASS - 24 text files checked, no non-ASCII bytes and no CRLF line endings found.
  * Evidence: `checked_text_files=24`, `status=0`.
* Command/check: `stat -c "%s bytes"` plus `file -b` for the three Phase 3 generated PNG files.
  * Result: PASS - all three generated asset files exist with expected 1672 x 941 PNG dimensions and recorded byte sizes.
  * Evidence: asset evidence listed above.
* UI product-surface check: N/A - validation and documentation artifact update only.
* UI craft check: N/A - validation and documentation artifact update only.

# 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-notes.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.
