# Implementation Summary

**Session ID**: `phase31-session04-extensions-and-agent-routes` **Completed**: 2026-06-24 **Duration**: 3-4 hours

***

## Overview

Phase 31 Session 04 made the deeper public-demo route families safe for static hosting. Hermes, Claude Code, OpenClaw, Knowledge Graph, Trend Finder, and AI Rogue now enter demo, read-only, snapshot, unavailable, or browser-local states before live bridge hooks can construct local `/__*` requests. Focused route and component tests now guard the hosted demo boundary.

## Technical Decisions

1. **Route-level demo coercion**: Public-demo mode is applied before live route hooks receive options, preventing unsafe local bridge URL construction.
2. **Allowlist-first media handling**: Trend Finder renders only reviewed `/demo/trend-finder-assets/*` URLs directly in hosted public-demo mode.
3. **Disabled-query refetch guard**: Knowledge Graph `refetch()` returns early when live queries are disabled, closing an imperative bypass.
4. **Browser-local AI Rogue contract**: AI Rogue remains visible in public-demo mode while copy and controls make persistence explicitly browser-local.

## Test Results

| Metric                    | Value         |
| ------------------------- | ------------- |
| Tests                     | 4218          |
| Passed                    | 4218          |
| Focused public-demo tests | 91 passed     |
| Coverage                  | Not collected |

Additional gates passed: `bun run lint`, `bun run format:check`, `bun run typecheck`, `bun run typecheck:scripts`, `git diff --check`, ASCII scan, and LF scan.

***

## Lessons Learned

1. Disabled React Query hooks can still be executed through imperative refetches unless the returned API is guarded.
2. Route-level no-bridge fetch recorders catch unsafe requests that component checks can miss.
3. Hosted demo copy needs separate product-facing branches from local demo and operator diagnostics copy.

***

## Future Considerations

Items for future sessions:

1. Session 05 should package only the now-safe route behavior into the Pages build and deployment scaffold.
2. Session 06 should expand from focused no-bridge tests to full generated demo route smoke and privacy scans.
3. Session 07 should polish frozen-snapshot provenance and mobile release readiness.

# 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/phase31-session04-extensions-and-agent-routes/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.
