# Implementation Summary

**Session ID**: `phase30-session04-economy-and-ledger` **Completed**: 2026-06-22 **Duration**: 1 hour

***

## Overview

Session 04 replaced the AI Rogue Ledger readiness shell with a deterministic, browser-safe Insight Shards economy and manual claim flow. The implementation adds a pure `deriveAiRogueEconomy(liveData)` transform, locked 40/25/20/10/5 source weights, daily caps, stable redemption keys, a narrow localStorage claimed-key guard, reward icon rendering, Ledger UI states, and focused unit, component, route, and Playwright coverage.

## Technical Decisions

1. **Pure economy boundary**: Kept scoring in `deriveAiRogueEconomy(liveData)` with no browser side effects so Session 05 can attach durable wallet and ledger persistence without changing the scoring contract.
2. **Unavailable is not punitive**: Missing pricing, example-only data, unknown tokens, and absent provider telemetry produce unavailable source states rather than reducing other source contributions.
3. **Temporary narrow localStorage guard**: Added only claimed redemption keys and safe metadata in localStorage to satisfy refresh idempotency while leaving IndexedDB wallet, ledger, saves, and reset behavior to Session 05.
4. **Privacy-safe provenance**: Rendered counts, capped source labels, dates, provider categories, and cap states only; raw prompts, transcripts, commands, private paths, credentials, logs, and provider payloads are excluded from storage and UI text.

## Test Results

| Metric   | Value                           |
| -------- | ------------------------------- |
| Tests    | 3914 runtime/browser tests      |
| Passed   | 3914                            |
| Coverage | Not collected during validation |

Commands passed:

* `bun run test`
* `bun run test -- src/extensions/ai-rogue/__tests__/economy.test.ts src/extensions/ai-rogue/__tests__/claim-store.test.ts src/extensions/ai-rogue/__tests__/client.test.tsx src/routes/__tests__/extensions-routes.test.tsx`
* `bun run test:e2e -- tests/e2e/ai-rogue-ledger.spec.ts`
* `bun run typecheck`

## Lessons Learned

1. The Ledger can derive useful rewards from existing browser-visible LiveData branches without adding collectors, network calls, hosted storage, or raw private telemetry exposure.
2. Stable redemption keys need multiple safe components because activity data can be partial, example-only, or missing provider pricing.
3. Keeping claim idempotency tiny and explicit avoids preempting the fuller Session 05 persistence and migration design.

***

## Future Considerations

Items for future sessions:

1. Promote the claim record into the versioned IndexedDB wallet and ledger contract in Session 05.
2. Connect spendable Insight Shards to Loadout upgrades and play runtime rewards in Session 07.
3. Keep the capped token/spend source tunable after real gameplay balancing data exists.

## 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-session04-economy-and-ledger/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.
