# Phase 144 Summary

Status: implemented in working tree

## Goal

Close the still-open `999.27` intake-honesty remainder by making source-backed
assumptions, reading-depth limits, and weak/conflicting evidence first-class on
the real `L1` operator path.

## What Landed

- strengthened `l1_source_intake` operator rendering through:
  - `research/knowledge-hub/knowledge_hub/l1_source_intake_support.py`
  - `research/knowledge-hub/knowledge_hub/runtime_read_path_support.py`
  - `research/knowledge-hub/knowledge_hub/kernel_markdown_renderers.py`
  - `research/knowledge-hub/knowledge_hub/topic_shell_support.py`
- one new isolated acceptance lane:
  - `research/knowledge-hub/runtime/scripts/run_l1_assumption_depth_acceptance.py`
- one new contract-test slice:
  - `research/knowledge-hub/tests/test_l1_assumption_depth_contracts.py`
- runtime acceptance coverage in:
  - `research/knowledge-hub/tests/test_runtime_scripts.py`
- documentation updates across:
  - `README.md`
  - `research/knowledge-hub/README.md`
  - `research/knowledge-hub/runtime/README.md`
  - `research/knowledge-hub/runtime/AITP_TEST_RUNBOOK.md`
- opportunistic isolation fix for:
  - `research/knowledge-hub/runtime/scripts/run_l1_method_specificity_acceptance.py`

## Outcome

Phase `144` now closes the bounded `L1` assumption/depth surface through the
existing `l1_source_intake` path:

- assumptions remain source-backed and visible
- partial reading depth stays explicit
- contradiction candidates stay operator-visible on the dashboard, research
  contract, runtime protocol note, and `L1` vault wiki surface
