# Implementation Summary

**Session ID**: `phase19-session02-documents-gallery-write` **Completed**: 2026-06-02 **Duration**: \~0.4 hours

***

## Overview

Completed the Hermes Documents Gallery write surface for Phase 19. The session ported the document list, preview, trash, delete, restore, and purge flows into the AI OS Hermes architecture, added hook-layer polling for live document and trash reads, extended Hermes page and browser coverage, and closed the phase with validation, state updates, and archival bookkeeping.

## Technical Decisions

1. **Keep document polling in the hook layer**: live refresh uses TanStack Query intervals instead of raw component timers.
2. **Preserve admin-gated destructive writes**: delete, restore, and purge stay behind the existing Hermes admin contract with confirmation and duplicate trigger prevention.

***

## Test Results

| Metric   | Value        |
| -------- | ------------ |
| Tests    | 134          |
| Passed   | 134          |
| Coverage | Not measured |

***

## Lessons Learned

1. The existing Hermes hook and admin contracts already exposed the needed data and write boundaries, so the safe implementation path was focused UI composition plus tests.
2. Bounded feedback and explicit confirmation states are essential for a local-filesystem destructive surface.

***

## Future Considerations

1. Carry the same hook-layer polling pattern into the remaining Hermes long-tail surfaces.
2. Keep the document root decision and local-path privacy boundary documented if the bridge configuration changes in a later phase.

# 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/phase19-session02-documents-gallery-write/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.
