# Implementation Summary

**Session ID**: `phase39-session07-real-content-expansion-path` **Completed**: 2026-07-01 **Duration**: 0.5 hours

***

## Overview

Session 07 activated the prepared `insight-beetle` enemy as real authored AI Rogue content on the depth-4 `firewall-gauntlet` floor. The work used existing templates, committed frames, the existing `corruption` audio family, and current save schema version 1 while proving the path with focused generation, behavior, render, asset, audio, and save tests.

| ---------------------------------------------------------------------- | ------------------------------------------------------------------------------------------- |
| `src/extensions/ai-rogue/runtime/content/levels.ts`                    | Added `insight-beetle` to the authored depth-4 enemy guarantee.                             |
| `src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts`     | Asserted registry activation, safe copy, and validation coverage for the new enemy path.    |
| `src/extensions/ai-rogue/runtime/__tests__/content-baseline.test.ts`   | Updated authored depth-4 baseline expectations.                                             |
| `src/extensions/ai-rogue/runtime/__tests__/world.test.ts`              | Proved generated depth-4 worlds include the guaranteed enemy while preserving route safety. |
| `src/extensions/ai-rogue/runtime/__tests__/golden-determinism.test.ts` | Updated intentional depth-4 deterministic summaries.                                        |
| `src/extensions/ai-rogue/runtime/__tests__/ecology.test.ts`            | Kept template behavior aligned with authored activation.                                    |
| `src/extensions/ai-rogue/runtime/__tests__/enemy-effects.test.ts`      | Added death reward coverage for matching and non-matching kill sources.                     |
| `src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts`       | Proved stable render labels and committed frame projection.                                 |
| `src/extensions/ai-rogue/runtime/__tests__/assets.test.ts`             | Proved derived frame requirements include the five `insight-beetle` frames.                 |
| `src/extensions/ai-rogue/runtime/__tests__/audio.test.ts`              | Proved `insight-beetle` uses the existing `corruption` audio family and cue routing.        |
| `src/extensions/ai-rogue/__tests__/save-schema-parity.test.ts`         | Added parser-owned persisted ID parity coverage.                                            |
| `src/extensions/ai-rogue/__tests__/save-schema.test.ts`                | Proved parse and hydrate behavior under save schema version 1.                              |
| `docs/ongoing-projects/ai-rogue-phase-39-asset-generation-plan.md`     | Recorded the Session 07 prepared-enemy choice and no-new-media rationale.                   |

## Technical Decisions

1. **Use spec-owned activation**: `insight-beetle` enters play through one authored level guarantee, keeping level intent in the registry instead of scattered depth branches.
2. **Reuse existing catalogs and media**: The enemy uses existing template behavior, committed frames, and the existing `corruption` audio family, so no new media, audio maps, or schema version bump was needed.
3. **Prove parser-owned persistence**: Save tests assert parse, hydrate, and parity behavior directly under schema version 1 instead of relying on runtime enum inference.

***

## Test Results

| Metric   | Value                          |
| -------- | ------------------------------ |
| Tests    | 4662                           |
| Passed   | 4662                           |
| Coverage | Not reported by `bun run test` |

Additional validation:

* Focused content and generation suite: 4 files, 22 tests passed.
* Focused behavior, media, and save suite: 7 files, 123 tests passed.
* Lint, app typecheck, script typecheck, asset-size, whitespace, ASCII/LF, and privacy scans passed.

***

## Lessons Learned

1. A prepared standard enemy can now be activated through catalog/spec work plus focused tests.
2. Existing enemy audio and frame metadata are sufficient to validate a real content addition without renderer or audio switch changes.
3. Save compatibility remains explicit when parser-owned ID parity tests cover newly activated persisted IDs.

***

## Future Considerations

Items for future sessions:

1. Session 08 should harden validation and documentation around the completed level-authoring workflow.
2. Future real content can add one new content type at a time, starting from catalog entries and authored level guarantees.
3. Browser proof should be added whenever a future session changes route-visible rendering, controls, or audio unlock behavior.

## 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/phase39-session07-real-content-expansion-path/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.
