# Phase 64: Human-Facing Graph Reports And Derived Navigation - Context

**Gathered:** 2026-04-11
**Status:** Implemented and verified
**Mode:** Brownfield continuation after closing Phase `63`

<domain>
## Phase Boundary

Add an operator-facing compiled graph surface over bounded canonical `L2`:

- a human-readable graph report
- Obsidian-friendly derived navigation pages
- a real service/CLI entrypoint for regenerating those derived views

This phase is about graph inspection and navigation.
It is not about reopening retrieval semantics or docs-parity closure yet.

</domain>

<decisions>
## Implementation Decisions

### Locked decisions

- Keep graph reporting in compiled `L2`, not canonical `L2`.
- Expose the new surface through a dedicated production command:
  - `aitp compile-l2-graph-report`
- Reuse the bounded seeded graph and canonical inputs only; do not introduce a
  second source of truth.

### the agent's Discretion

- Exact graph-report sections and navigation page layout.
- How many hub units and relation examples to surface by default.

</decisions>

<code_context>
## Existing Code Insights

- `compile-l2-map` already wrote a bounded workspace memory map, but it did not
  yet give operators navigable graph pages.
- The seeded TFIM graph was already rich enough to support real hub and
  neighbor views without inventing extra ontology.
- `aitp_service.py` and `aitp_cli.py` remain under watch, so the new behavior
  had to stay in `l2_compiler.py` plus the extracted compiler handler.

</code_context>

<specifics>
## Specific Ideas

- Materialize `workspace_graph_report.json|md` under `canonical/compiled/`.
- Materialize `canonical/compiled/derived_navigation/index.md` plus one page per
  unit with incoming and outgoing relations.
- Surface graph hubs, relation clusters, and consultation anchors in the
  human-facing report.

</specifics>

<deferred>
## Deferred Ideas

- Broader public docs parity for the new graph-report command.
- Final acceptance packaging and milestone closeout.
