# Phase 165.5-03 Community Overview Summary

Status: implemented in working tree

## Goal

Close the next `165.5-03 / 999.84` slice by making the Obsidian-compatible
concept-graph export navigable at the community level and by proving that
unclustered nodes still land in a stable browseable layout.

## What Landed

- `obsidian_graph_export.py` now writes one community overview page per export
  folder:
  - `concept-graph/<community-slug>/index.md`
- the top-level concept-graph index now links both:
  - the community overview page
  - the node notes inside that community
- unclustered nodes now explicitly materialize under:
  - `concept-graph/unclustered/`
  - with their own `index.md`
- export manifest payload now records:
  - `summary.community_page_count`
  - `community_page_paths[]`
  - per-community `index_path`
- `l1_vault_support.py` now includes community overview pages in the wiki
  `page_paths` list, so `page_count` and enumerated page paths stay aligned

## Verification

- `python -m pytest research/knowledge-hub/tests/test_obsidian_graph_export.py -q`
- `python -m pytest research/knowledge-hub/tests/test_runtime_scripts.py -q -k "l1_vault or l1_concept_graph or obsidian_export"`
- `python -m pytest research/knowledge-hub/tests/test_aitp_service.py -q -k "l1_vault or concept_graph"`
- `python research/knowledge-hub/runtime/scripts/run_l1_graph_obsidian_export_acceptance.py --json`

## Outcome

`165.5-03` now has a second closed slice:

- the repo-local Obsidian graph export is no longer just a flat note dump
- operators can browse by community folder before drilling into node notes
- graphs without detected communities still remain readable and deterministic
  through the explicit `unclustered/` lane

## Remaining Open Work Inside 165.5-03 / 999.84

- richer node-page content:
  - source provenance excerpts
  - clearer directionality wording for relations
- decide whether the export should remain repo-local or gain an explicit bridge
  into the external theoretical-physics brain
- broader acceptance coverage for multi-community nodes that belong to several
  clusters at once
