# Implementation Summary

**Session ID**: `phase30-session08-progression-depth` **Completed**: 2026-06-22 **Duration**: 0.7 hours

***

## Overview

Completed the Phase 30 progression-depth session for AI Rogue. The session adds browser-safe progression derivation from existing AI OS signals, deterministic class and relic loadouts, capped model-flavored resources, richer objective and enemy behavior, local achievement metadata, and Play/Loadout UI integration without adding backend services, remote loading, collectors, or worker runtime scope.

## Technical Decisions

1. **Pure progression helper**: LiveData-derived progression stays in a browser-safe TypeScript helper so runtime simulation does not import browser storage, React, PixiJS, or raw operator data.
2. **Additive save schema**: Progression metadata uses Zod defaults and bounded arrays so older saves, wallets, ledgers, and run-history records continue to parse safely.
3. **Worker remains deferred**: Focused runtime evidence did not show input blockage, render starvation, or save/load jank, so Session 08 documented the decision instead of adding a worker protocol prematurely.

## Test Results

| Metric                             | Value         |
| ---------------------------------- | ------------- |
| Full Vitest tests                  | 3989          |
| Full Vitest passed                 | 3989          |
| Focused AI Rogue Vitest tests      | 108           |
| Focused AI Rogue Vitest passed     | 108           |
| Focused AI Rogue Playwright tests  | 7             |
| Focused AI Rogue Playwright passed | 7             |
| Coverage                           | Not collected |

## Lessons Learned

1. Full LiveData query data is needed for Play and Loadout progression; extension item props alone are not enough to derive the safe progression profile.
2. The existing IndexedDB wallet/run-history transaction path can carry progression selections and achievements without adding a new persistence surface.

***

## Future Considerations

Items for future sessions:

1. Session 09 can tune mobile layout, pointer ergonomics, and content polish using the progression HUD and Loadout controls now in place.
2. Revisit worker simulation only if later profiling shows input blockage, render starvation, or save/load jank that the current runtime path cannot absorb.

## 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/phase30-session08-progression-depth/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.
