# Implementation Summary

**Session ID**: `phase15-session06-cross-linking-and-copy-consistency-pass` **Package**: `public-website` **Completed**: 2026-06-02 **Duration**: 0.5 hours

***

## Overview

Closed the final Phase 15 public-website consistency pass by aligning the shared route contract, expanding primary/footer navigation coverage, tightening header and mobile navigation behavior, and adding a deterministic built-site checker for routes, links, metadata, legal markers, and guarded copy. The session also closed the phase records, updated the package version, and marked Phase 15 complete in the spec system.

## Technical Decisions

1. **Shared route contract first**: Centralized first-release routes, approved external destinations, and copy guardrails in `site.ts` so navigation, content, and validation all use the same source of truth.
2. **Deterministic validation**: Used a local Node checker over built output instead of live link checks so validation stays reproducible and no-network.

***

## Test Results

| Metric   | Value |
| -------- | ----- |
| Tests    | 3     |
| Passed   | 3     |
| Coverage | N/A   |

***

## Lessons Learned

1. Once the site reached the final content pass, navigation drift was best caught by validating built output instead of source strings alone.
2. Closing the phase cleanly required updating both the session records and the master PRD, not just the implementation files.

***

## Future Considerations

Items for future sessions:

1. Phase 16 should focus on responsive/accessibility hardening, performance, build gates, deployment, and launch evidence.
2. Keep the checker current if new first-release routes or approved external destinations are added later.

## 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/phase15-session06-cross-linking-and-copy-consistency-pass/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.
