# Phase 41 Plan 01 Summary

Date: 2026-04-09
Status: Complete

## One-line outcome

AITP now exposes explicit collaborator-routing guidance, so lane-preference
mismatch and human override surfaces are visible instead of being buried in raw
runtime notes.

## What changed

- Added `collaborator_routing_guidance.json` and
  `collaborator_routing_guidance.md` under the runtime topic root.
- Added a runtime bundle surface with:
  - current task type
  - current lane and lane family
  - collaborator preferred lanes
  - alignment status
  - override surfaces
  - recommended steering action
- Elevated the routing note into `must_read_now` when collaborator preference
  and current lane materially disagree.

## Verification

- `python -m pytest research/knowledge-hub/tests/test_schema_contracts.py -q`
  - `12 passed`
- `python -m pytest research/knowledge-hub/tests/test_runtime_profiles_and_projections.py -k "collaborator_routing_guidance" -q`
  - `1 passed`
- `python -m pytest research/knowledge-hub/tests/test_runtime_profiles_and_projections.py research/knowledge-hub/tests/test_schema_contracts.py -q`
  - `29 passed`
- `python -m pytest research/knowledge-hub/tests/test_aitp_service.py research/knowledge-hub/tests/test_aitp_cli.py research/knowledge-hub/tests/test_aitp_cli_e2e.py research/knowledge-hub/tests/test_runtime_profiles_and_projections.py research/knowledge-hub/tests/test_schema_contracts.py research/knowledge-hub/tests/test_l2_graph_activation.py research/knowledge-hub/tests/test_topic_start_regressions.py -q`
  - `138 passed`

## Physicist-Facing Judgment

From the perspective of a theoretical physicist, this phase matters because the
system is now more transparent about collaborator fit:

1. AITP can say when the current route disagrees with recorded collaborator
   lane preferences,
2. the human can see which surfaces to edit to redirect the route,
3. collaborator memory still remains steering context, not canonical domain
   truth.

## Next Step

`v1.35` is now complete in bounded GSD terms.

The next cycle should probably decide whether to:
- deepen task-type-by-lane templates into actual queue/routing generation, or
- tackle remaining `L0/L1` and long-horizon collaborator-memory gaps.
