# Phase 146: Record Human Modifications On L2 Approval - Context

**Gathered:** 2026-04-12
**Status:** Ready for execution

<domain>
## Phase Boundary

This phase owns the next promotion-gate honesty slice.

The phase should:

- record what the human changed on approval
- keep those modifications durable on the promotion-gate path
- expose the change record through replay/read surfaces

</domain>

<decisions>
## Implementation Decisions

- **D-01:** Extend the existing promotion-gate and gate-log surfaces instead of
  inventing a separate evaluator log.
- **D-02:** Treat modified and unmodified approvals as distinct explicit states
  rather than collapsing them together.
- **D-03:** Keep the first slice bounded to approval-time modification records,
  not full post-hoc evaluator analytics.
- **D-04:** Add one isolated acceptance lane so the modified-approval path can
  close independently of wider promotion workflows.

</decisions>

## Deferred Ideas

- full evaluator-divergence analytics across many approvals
- broader competing-hypothesis or adjudication systems
- generalized human rewrite tracking beyond the L2 approval gate
