## Changes Summary

- My active S5-owned code changes are in `research/knowledge-hub/knowledge_hub/l2_compiler.py`, `research/knowledge-hub/knowledge_hub/l2_consultation_support.py`, and `research/knowledge-hub/knowledge_hub/l2_graph.py`.
- `research/knowledge-hub/knowledge_hub/l2_compiler.py`: added paired-backend drift-report compilation and markdown/json materialization.
- `research/knowledge-hub/knowledge_hub/l2_consultation_support.py`: added topic-locality helpers and summary-first progressive retrieval payload shaping.
- `research/knowledge-hub/knowledge_hub/l2_graph.py`: added topic-local ranking, progressive retrieval support, and canonical-index row normalization helpers.
- My active S5-owned data changes are new canonical GW/QSGW seed files under `research/knowledge-hub/canonical/`.
- Added reusable GW/QSGW concepts, methods, physical pictures, theorem packet, validation pattern, workflow, bridge, topic-skill projection, and seed note for L2 growth.
- `research/knowledge-hub/canonical/bridges/bridge--tfim-toy-model-code-method-bridge.json` currently shows a single additive reuse-receipt line in `git diff`; it is a clean one-hunk change rather than a visibly mixed merge hunk.
- All other files currently shown by `git diff --name-only` are owned by other sessions according to `docs/SESSION_COORDINATION_10WAY.md` and were not modified by me.

## Conflict Check

- Out-of-scope files: temporarily touched and then reverted/removed: `research/knowledge-hub/knowledge_hub/aitp_service.py`, `research/knowledge-hub/tests/test_l2_progressive_retrieval_and_drift.py`. No remaining active out-of-scope file edits from me.
- Conflict files: `research/knowledge-hub/canonical/bridges/bridge--tfim-toy-model-code-method-bridge.json` remains a coordination-sensitive file because `canonical/` is the shared S5 surface, but the current diff does not show a mixed conflict block. It looks like a single additive change and is being kept.
- Mode naming consistency: Yes. My active S5 changes do not introduce old runtime mode names as mode constants; retained strings such as `promoted` and `human_promoted` are promotion metadata, not runtime mode names.

## Test Results

- `python -m py_compile research/knowledge-hub/knowledge_hub/l2_compiler.py`
  Result: passed, exit code `0`
- `python -m py_compile research/knowledge-hub/knowledge_hub/l2_consultation_support.py`
  Result: passed, exit code `0`
- `python -m py_compile research/knowledge-hub/knowledge_hub/l2_graph.py`
  Result: passed, exit code `0`
- `python -m pytest research/knowledge-hub/tests/ -k "l2" -v`
  Result: `75 passed, 5 failed, 691 deselected`
  Failing tests:
  - `test_hs_positive_l2_acceptance_script_runs_on_isolated_work_root`
  - `test_librpa_qsgw_positive_l2_acceptance_script_runs_on_isolated_work_root`
  - `test_positive_negative_l2_coexistence_acceptance_script_runs_on_isolated_work_root`
  - `test_staged_l2_advancement_acceptance_script_runs_on_isolated_work_root`
  - `test_staged_l2_reentry_acceptance_script_runs_on_isolated_work_root`
  Shared failure cause from traceback:
  - `research/knowledge-hub/knowledge_hub/l1_source_intake_support.py`
  - `NameError: name 'reading_depth_state_from_row' is not defined`
  This is outside S5 ownership and appears to be an S6-side break, not an `l2_*.py` compile error.
- `python -m pytest research/knowledge-hub/tests/test_l2_progressive_retrieval_and_drift.py -v`
  Result after implementation: `4 passed in 0.55s`
- `python -m pytest research/knowledge-hub/tests/test_l2_graph_activation.py -v`
  Result: `9 passed in 1.23s`
- `python -m pytest research/knowledge-hub/tests/test_l2_backend_contracts.py -v`
  Result: `15 passed in 0.09s`
- `python -m pytest research/knowledge-hub/tests/test_l2_progressive_retrieval_and_drift.py research/knowledge-hub/tests/test_l2_graph_activation.py research/knowledge-hub/tests/test_l2_backend_contracts.py -q`
  Result: `28 passed in 2.16s`

## Issues

- The repository worktree is a mixed 10-session state; current `git diff --stat` reflects many other sessions' changes, not only S5.
- The compiled L2 drift report shows pre-existing Jones-side orphan edges and unresolved references in the shared canonical graph.
- `python -m pytest research/knowledge-hub/tests/ -k "l2" -v` is not fully green because runtime-script tests currently fail inside S6-owned `research/knowledge-hub/knowledge_hub/l1_source_intake_support.py` with `reading_depth_state_from_row` missing.
- GW/QSGW seed completeness check passed: concept, method, physical picture, theorem packet, validation pattern, workflow, bridge, topic-skill projection, seed note, and warning note files all exist.
- The TFIM bridge diff currently looks like a clean single additive line, not a visibly mixed multi-author hunk.

## Next Steps

- Keep working only in `l2_*.py` and the newly added canonical GW/QSGW seed files.
- Do not touch S6-owned `l1_source_intake_support.py`; report the failing `reading_depth_state_from_row` issue for coordination instead.
- If asked for more S5 work, focus on L2-only follow-up and avoid editing pre-existing shared canonical files without explicit coordination.
