# Implementation Summary

**Session ID**: `phase35-session05-persistence-schema-contracts` **Completed**: 2026-06-26 **Duration**: 1 hour

***

## Overview

Completed Phase 35 Session 05 by hardening AI Rogue browser-local persistence contracts before the later refactor sessions. The session made durable saved-run schema ownership explicit, kept durable-to-runtime conversion behind schema-owned helpers, strengthened claim and reset failure behavior, and added focused unit and browser coverage for wallet, ledger, save/load, reset, and storage failure paths.

## Technical Decisions

1. **Schema-owned durable names**: Durable saved-run records now use explicit saved-run schema/type names while preserving compatibility exports for existing durable consumers.
2. **Non-throwing hydration result**: Runtime load code now receives explicit ready, empty, and malformed results before surfacing stable product-facing errors.
3. **Persistence guards at the write boundary**: Direct claim writes normalize before wallet and ledger mutation and same-key duplicate submissions are rejected while a transaction is in flight.

## Test Results

| Metric   | Value                                      |
| -------- | ------------------------------------------ |
| Tests    | 4357 Vitest, 2 Playwright                  |
| Passed   | 4357 Vitest, 2 Playwright                  |
| Coverage | Not collected during this session closeout |

***

## Lessons Learned

1. Durable and live runtime naming needs to stay visibly separate because the data crosses different trust and lifecycle boundaries.
2. Storage failure behavior is easiest to preserve when tests cover adapter failures directly and product surfaces assert stable player-facing copy.

***

## Future Considerations

Items for future sessions:

1. Session 06 can refactor simulation ownership now that persistence contracts are protected by focused tests.
2. Session 08 should revisit `save-schema.ts` and `persistence.ts` file-size pressure after simulation and renderer ownership splits are complete.

# 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://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase35-session05-persistence-schema-contracts/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.
