# Implementation

<!-- High-signal implementation notes. Focus on material deviations and what future work must preserve; do not mirror every Plan ticket. -->

## Outcome

<!-- Summarize the final implementation state in one to three concise bullets. -->

## Deviations

<!-- Record material deviations using Current behavior, Deviation, Attention, and Evidence. When implementation is complete and none were found, write `None found.` -->

## Verification

<!-- Record representative final gates and results, not repetitive per-ticket command history. -->

## Spec Retrospective

<!-- Record at most one or two specific Research Findings, Design Decisions, or Plan weaknesses that should improve a future Spec, or `None.` -->
