# Implementation Summary

**Session ID**: `phase02-session01-product-surface-requirements-reconciliation` **Package**: Cross-package documentation (`.spec_system/PRD`, `docs`, `README.md`, app/package README references) **Completed**: 2026-05-29 **Duration**: 3 hours

***

## Overview

Reconciled the Phase 02 product and UX requirements with the shipped web surface, added the Phase 02 product-surface gap matrix, and closed Session 01 as a validated documentation baseline for the remaining Phase 02 sessions.

## Technical Decisions

1. Kept Session 01 documentation-focused so the remaining Phase 02 sessions can plan from a stable requirements baseline.
2. Treated historical `EXAMPLES/` material as traceability evidence only and did not promote it into product authority.

## Test Results

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

***

## Lessons Learned

1. The current web cockpit already covers most of the user surface, so the remaining work is cohesion and boundary clarity.
2. The public demo needs explicit no-workspace-package language to keep its standalone contract honest.

***

## Future Considerations

Items for future sessions:

1. Use the product-surface gap matrix as the primary routing table for Sessions 02-07.
2. Revalidate battlefield asset parity before any app or public-demo asset change lands.

## 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/phase02-session01-product-surface-requirements-reconciliation/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.
