# Phase 165.5-02 Graph Hyperedge Pattern Summary

Status: implemented in working tree

## Goal

Close the next `999.83` slice by making graph analysis detect cross-source
structural bridges from shared hyperedge patterns, not only from shared labels
or shared community names.

## What Landed

- `graph_analysis_tools.py` now emits
  `shared_hyperedge_pattern_bridge` connections when two or more sources share:
  - the same hyperedge relation
  - the same multi-node type signature
  - without requiring any shared node labels or shared community labels
- connection ranking now extends to a fourth deterministic bridge tier:
  - `shared_foundation_bridge`
  - `shared_concept_bridge`
  - `shared_community_bridge`
  - `shared_hyperedge_pattern_bridge`
- hyperedge-pattern rows now retain:
  - `pattern_relation`
  - `pattern_node_types`
  - representative source-local node labels in the human-readable detail text
- `suggest_questions()` now renders a structure-aware question form for this
  new bridge kind instead of using the generic semantic-bridge wording
- literature-intake fast-path staging inherits the new heuristic automatically:
  - graph-derived `physical_picture`
  - graph-derived `workflow`
  - provenance tag `graph_analysis_kind=shared_hyperedge_pattern_bridge`
- isolated acceptance now exists for the full path:
  - `runtime/scripts/run_l1_graph_hyperedge_pattern_acceptance.py`

## Verification

- `python -m pytest research/knowledge-hub/tests/test_graph_analysis_tools.py -q`
- `python -m pytest research/knowledge-hub/tests/test_literature_intake_support.py -q`
- `python -m pytest research/knowledge-hub/tests/test_runtime_scripts.py -q -k "graph_analysis or graph_diff or community_bridge or hyperedge_pattern or mode_enforcement"`
- `python -m pytest research/knowledge-hub/tests/test_aitp_service.py -q -k "graph_diff or literature_intake_stage"`
- `python -m pytest research/knowledge-hub/tests/test_runtime_profiles_and_projections.py -q -k "graph_analysis"`
- `python research/knowledge-hub/runtime/scripts/run_l1_graph_hyperedge_pattern_acceptance.py --json`

## Outcome

`999.83` now has another closed deterministic slice:

- AITP can surface cross-source graph bridges from shared derivation structure,
  not only from shared vocabulary
- those structural bridges can flow directly into bounded `L2` staging work via
  the existing literature fast path
- the `hyperedges` portion of the concept-graph contract is now used by the
  analysis layer instead of remaining dead weight

## Remaining Open Work Inside 165.5-02 / 999.83

- decide whether relation-pattern bridges without hyperedges are still worth
  adding, or whether the current deterministic bridge set is sufficient
- route- or promotion-level policy for how graph-analysis signals should affect
  downstream prioritization or escalation
- any later decision to move from `999.83` completion into `165.5-03 / 999.84`
  Obsidian graph export
