# Implementation Summary

**Session ID**: `phase24-session04-source-setup-target-configuration` **Completed**: 2026-06-08 **Duration**: Approx. 1.7 hours

***

## Overview

Implemented reviewed-source setup for Trend Finder through a browser-safe Source Setup panel, a token-gated loopback bridge, private source config read and write helpers, and additive browser contracts. The session keeps source setup limited to reviewed source IDs and whitelisted target fields, while preserving parser compatibility and redacting credentials, raw Actor inputs, and other private runtime data.

## Technical Decisions

1. Reviewed source IDs remain the only editable source entries. The UI and bridge only accept declarations that are already reviewed and explicitly whitelisted.
2. Private config writes stay additive and parser-compatible. The helper preserves supported fields so existing env/file-driven behavior continues to work.
3. Bridge responses stay browser-safe. Diagnostics expose readiness and warnings, not secrets, raw Actor input, Dataset rows, or config paths.

## Test Results

| Metric   | Value |
| -------- | ----- |
| Tests    | 17    |
| Passed   | 17    |
| Coverage | N/A   |

***

## Lessons Learned

1. Source setup state needs a separate browser-safe projection from the private config file to keep the UI operable without leaking implementation details.
2. Loopback and token checks must be enforced at the bridge boundary, not just in the UI, to preserve the local-only trust model.

***

## Future Considerations

Items for future sessions:

1. Add scheduler first-run and live progress controls in Session 05.
2. Add dense Signal Workbench triage state in Session 06.
3. Add optional static Brief export in Session 07.

# 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/phase24-session04-source-setup-target-configuration/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.
