# Implementation Summary

**Session ID**: `phase24-session09-validation-and-documentation` **Package**: apps/web **Completed**: 2026-07-08 **Duration**: 1 hour

***

## Overview

Session 09 closed Phase 24 by validating the live tier and combat playback slice, recording phase-exit evidence, updating stable docs and PRDs, and marking the session and phase complete. The closeout preserved the Phase 24 boundaries: no new protocol event, server route, storage key, hosted claim, runtime generated-asset image load, reward path, XP, loot, banner, public-demo synthetic front, certification claim, or trusted-erasure claim.

## Technical Decisions

1. **Evidence-first closeout**: Used focused tests, root tests, typechecks, format/lint checks, source scans, and phase audit evidence before marking state complete.
2. **Package-local version bump**: Bumped `apps/web/package.json` only because the monorepo package context is `apps/web`; root version remains separately managed.
3. **Phase archive after state update**: Marked Phase 24 complete in state and PRDs, then archived the phase PRD as the final session-loop artifact.

## Test Results

| Metric                 | Value                              |
| ---------------------- | ---------------------------------- |
| Focused Phase 24 tests | 238 passed / 0 failed              |
| Root tests             | 3395 passed / 1 skipped / 0 failed |
| Web typecheck          | PASS                               |
| Workspace typecheck    | PASS                               |
| Format check           | PASS                               |
| Lint                   | PASS                               |
| Coverage               | Not collected                      |

Existing React `act(...)` warnings printed from `apps/web/tests/Battlefield.test.tsx`, but the focused and root test commands exited 0 with no failed tests.

***

## Lessons Learned

1. Closeout docs need a final status pass after `validate` and `updateprd` because evidence-recorded wording is intentionally conservative before workflow completion.
2. The installed apex-spec script path is the reliable analyzer source in this checkout because `.spec_system/scripts/` is not present.

***

## Future Considerations

Items for future sessions:

1. Run `audit` next because Phase 24 is complete and the workflow is entering Phase Transition.
2. Future game-design phases should build on the completed Phase 24 baseline without adding a second projection authority or broadening hosted, protocol, storage, reward, public-demo, or trusted-erasure claims.

## 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-session09-validation-and-documentation/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.
