# Phase 33 Plan 01 Summary

Date: 2026-04-05
Status: Complete

## One-line outcome

`v1.7` closed with tighter kernel maintainability budgets, explicit docs for
the newly extracted boundaries, and regression coverage that locks those
boundary claims in place.

## What changed

- Documented the extracted kernel boundaries and their ownership surfaces.
- Tightened maintainability guardrails after the front-door, service, and CLI
  handler extractions landed.
- Closed the `v1.7` milestone planning state with the new maintainability and
  regression lock in place.

## Verification

- Retrospective closure: the shipped `v1.7` roadmap/project/milestone records
  this maintainability and regression lock as complete.
- The original command output was not preserved in the phase directory, so this
  summary captures the shipped result rather than fabricating detailed counts.

## Notes

- This summary was written retrospectively to close the missing phase record.
- The remaining hotspot work continued in the later kernel decomposition
  milestones.
