# Phase 69: Docs, Acceptance, And Regression Closure - Context

**Gathered:** 2026-04-11
**Status:** Implemented and verified
**Mode:** Brownfield continuation after closing Phase `68`

<domain>
## Phase Boundary

Close `v1.46` with:

- docs parity for the new source catalog and traversal commands
- a non-mocked acceptance path for the Layer 0 reuse surface
- final milestone-close regression evidence

This phase is about milestone closure.
It is not about adding another source-analysis feature.

</domain>

<decisions>
## Implementation Decisions

### Locked decisions

- Add a dedicated acceptance script for the source catalog surface instead of
  overloading the existing L2 acceptance path.
- Public docs must mention the new commands and the new acceptance script.
- The acceptance script must exercise both compiled artifacts and runtime
  `status --json` fidelity output.

### the agent's Discretion

- Exact placement of the new command list and acceptance note in public docs.
- Exact temp-kernel fixture used by the acceptance script.

<code_context>
## Existing Code Insights

- Phases `66` through `68` already delivered source catalog compilation,
  traversal/family reuse, and runtime fidelity surfaces through production code.
- The remaining mismatch was discoverability and a non-mocked acceptance path
  that exercised those new commands on an isolated kernel root.

</code_context>

<specifics>
## Specific Ideas

- Add `compile-source-catalog`, `trace-source-citations`, and
  `compile-source-family` to root and kernel command docs.
- Add `run_source_catalog_acceptance.py --json` to runtime docs and the test
  runbook.
- Close the milestone with final traceability docs under `.planning/milestones/`.

</specifics>

<deferred>
## Deferred Ideas

- next milestone selection after `v1.46` archive
