## Modified Files

S6-owned files currently modified by this session:

```text
research/knowledge-hub/knowledge_hub/l1_source_bridge_support.py
research/knowledge-hub/knowledge_hub/l1_source_intake_support.py
research/knowledge-hub/knowledge_hub/l1_vault_support.py
research/knowledge-hub/knowledge_hub/l1_deep_reading_support.py
```

## Changes Summary

- `research/knowledge-hub/knowledge_hub/l1_deep_reading_support.py`
  - New helper module for deep-reading state merge, fragment selection by reading depth, assumption/regime extraction, and pairwise regime/notation comparison.
  - Added docstrings for the public/new helper functions.

- `research/knowledge-hub/knowledge_hub/l1_source_intake_support.py`
  - Extended L1 intake with richer per-source reading-depth state, transition history, assumption/regime/notation enrichment, and pairwise contradiction context.
  - Restored and updated the public summary/render helpers used by vault/runtime surfaces, including regime overlap and notation alignment summaries.
  - Added docstrings for the newly added summary helper functions.

- `research/knowledge-hub/knowledge_hub/l1_vault_support.py`
  - Renders richer L1 intake information into the vault source-intake page.
  - Surfaces reading-depth state/history, regime overlap, notation alignment, and notation tension.

- `research/knowledge-hub/knowledge_hub/l1_source_bridge_support.py`
  - Extends source anchors with reading-depth, confidence, locator, contradiction, regime-overlap, notation-alignment, and notation-tension context.

## Conflict Check

- 越界文件: 无
- 冲突文件: 无直接文件所有权冲突；当前保留改动均在 S6 owns 范围内
- 模式名一致性: 是
  - 当前保留的 S6 文件中没有把 `discussion/verify/promote` 当作运行模式写回代码
  - `l1_deep_reading_support.py` 中出现的 `discussion` 仅是 section heading 关键词，不是 mode constant

## Test Results

Ran:

```text
python -m py_compile research/knowledge-hub/knowledge_hub/l1_deep_reading_support.py
python -m py_compile research/knowledge-hub/knowledge_hub/l1_source_intake_support.py
python -m py_compile research/knowledge-hub/knowledge_hub/l1_vault_support.py
python -m py_compile research/knowledge-hub/knowledge_hub/l1_source_bridge_support.py
```

Result:

```text
all four commands passed
```

Ran:

```text
python -m pytest research/knowledge-hub/tests/ -k "l1" -v
```

Result:

```text
blocked during collection by a non-S6 workspace error:
ModuleNotFoundError: No module named 'knowledge_hub.research_judgment_support'

Import chain:
knowledge_hub.aitp_service
-> knowledge_hub.runtime_bundle_support
-> knowledge_hub.research_judgment_runtime_support
-> knowledge_hub.research_judgment_support
```

This blocker is outside S6 ownership and was not modified here.

Supplemental S6-only verification:

```text
- AST docstring check: passed for the new public helper functions in
  l1_deep_reading_support.py and the new summary helpers in
  l1_source_intake_support.py
- Deep-reading fragment-selection probe:
  - `deepxiv_sections` keeps `summary` deferred
  - `Setup` / `Results` section fragments are selected
- Pairwise comparison probe:
  - regime overlap rows produced `disjoint`, `compatible`, and `partial`
  - notation alignment rows produced different-symbol/same-concept mappings
  - notation tension rows produced same-symbol/different-meaning mappings
```

## Issues

- The requested `pytest -k "l1"` command is currently blocked by a non-S6 collection error in the research-judgment path:
  - `research/knowledge-hub/knowledge_hub/runtime_bundle_support.py`
  - `research/knowledge-hub/knowledge_hub/research_judgment_runtime_support.py`
  - missing import target `research/knowledge-hub/knowledge_hub/research_judgment_support.py`
- This is outside the four S6-owned files, so it was recorded but not fixed.

## Next Steps

- Wait for the non-S6 import blocker to be resolved, then re-run:

```text
python -m pytest research/knowledge-hub/tests/ -k "l1" -v
```

- If that blocker clears and any remaining failures are still inside the S6 surface, fix them only in:
  - `research/knowledge-hub/knowledge_hub/l1_deep_reading_support.py`
  - `research/knowledge-hub/knowledge_hub/l1_source_intake_support.py`
  - `research/knowledge-hub/knowledge_hub/l1_vault_support.py`
  - `research/knowledge-hub/knowledge_hub/l1_source_bridge_support.py`
