# Implementation Summary

**Session ID**: `phase18-session07-scan-orchestration-and-quest-ignore-patterns` **Package**: Cross-package (apps/server, apps/web) **Completed**: 2026-06-10 **Duration**: 3.5 hours

***

## Overview

Implemented the Quest Board scan orchestration layer for Phase 18 session 07. The server now owns full, diff, and daily codebase scans with single-flight status tracking, last scanned commit persistence, and stale-startup triggering. The scan path also applies merged ignore patterns from the repo-level `.factionos-questignore` file and the web Settings payload before persisting issues through the manager-owned Quest Board state.

## Technical Decisions

1. **Manager-owned scan state**: scan status and issue persistence flow through `SuggestionManager` to keep snapshot emission and disk writes consistent.
2. **Dependency-free ignore matching**: `.factionos-questignore` and Settings patterns are normalized and matched with simple path-segment logic instead of introducing a new glob dependency.

***

## Test Results

| Metric   | Value                           |
| -------- | ------------------------------- |
| Tests    | 60                              |
| Passed   | 60                              |
| Coverage | Not reported by the focused run |

***

## Lessons Learned

1. The scan route needs explicit in-flight protection so startup work and manual triggers do not race.
2. Ignore handling is safer when it is applied before persistence, not only during UI filtering.

***

## Future Considerations

Items for future sessions:

1. Add on-demand analysis and project scan engines.
2. Finish typed Quest Board card rendering and action shortcuts.

# 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://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase18-session07-scan-orchestration-and-quest-ignore-patterns/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.
