# Implementation Summary

**Session ID**: `phase19-session16-ergonomics-and-documentation` **Package**: cross-cutting (`null`), primary implementation in `apps/web` **Completed**: 2026-06-28 **Duration**: 2 hours

***

## Overview

Session 16 closed Phase 19 by adding command-center ergonomics, safe keyboard workflows, adjacent-surface cross-links, desktop/mobile browser coverage, and stable documentation. The work preserved local-first, no-hosted, no-remote, and unsupported-executor boundaries while making existing command-center controls faster to operate.

## Technical Decisions

1. **Shortcut routing stays pure before dispatch**: `commandCenterShortcuts.ts` resolves semantic actions, target labels, selected attention rows, queue cycling, and disabled reasons before UI callbacks run.
2. **Mutating shortcuts require visible targets**: approve/reject shortcuts resolve only when a visible focused or selected pending attention item is unambiguous and not already in flight.
3. **Cross-links are data-driven**: adjacent-surface rows are centralized so product copy, availability, destination kind, and no-claim states can be tested directly.
4. **Playwright must run in app projects**: the new command-center e2e file was wired into desktop and mobile app project matches so browser coverage is not orphaned.

## Lessons Learned

1. Shortcut entry points need retrying focus helpers after tab switches and drawers because DOM presence does not guarantee active focus.
2. Product-facing no-claim rows are safer than hiding unsupported adjacent surfaces when the command center needs to explain current capability.

***

## Future Considerations

Items for future sessions:

1. Keep remote access, hosted behavior, and unsupported executor families as no-claim rows until source-backed implementation, tests, docs, and release evidence exist.
2. Add remappable shortcuts only after the current static shortcut model has a persisted settings contract and accessibility copy.
3. Preserve the Playwright app-project match when adding focused e2e files so new browser coverage runs in both desktop and mobile projects.

## 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/phase19-session16-ergonomics-and-documentation/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.
