# Neon Human Review Packet

- status: `candidate_applied_for_listening_review`
- domain: `audio_mix`
- evidence_role_pattern: `interaction_snapshots`
- requested_intent: apply reviewed candidate: guitar -0.02
- selected_song: Monkberry Moon Delight (Tab)

## Recommendation

- action: `listen_to_applied_candidate`
- candidate: `guitar -0.02`
- candidate_action: `set_mixer_level guitar: 0.55 -> 0.53 (-0.02)`
- reason: All objective claim receipts passed for this candidate; ranking only orders listening review.

## Objective Receipts

- supported_candidates: `1`
- rejected_candidates: `0`
- state_restored_after_loop: `true`
- candidate_actions_are_transient: `false`
- no_permanent_edit_unless_apply_best: `false`
- approved_candidate_applied: `true`
- approval_mode: `mixing_canon_surrogate`
- approval_basis: Conservative mixing-canon development surrogate: review candidate guitar -0.02 sets guitar from 0.55 to 0.53 with absolute level delta <= 0.12 after objective receipts, section-energy guardrails, clipping/headroom/low-level checks, and state-restoration checks passed. This keeps development moving and still requires listening review before treating the result as a subjective mix preference.

## Ranking

- metric: `guardrail_preserving_section_energy_review_order`
- role: `review_order_only`
- lower_is_better: `true`
- baseline: `62.2241`
- best: `62.4434`
- delta: `-0.2193`

## Candidate Section Energy Details

These loudness-style and section-energy comparisons are review aids. They rank and reject candidates by objective receipts; they do not prove subjective mix quality.

### Supported: guitar -0.02

- candidate: `guitar -0.02`
- role: `metric_supported_review_order`
- required_section_energy_floors_preserved: `true`
- guardrails_preserved: `true`
- boundary: Loudness-style and section-energy metrics rank candidates for review; they do not prove subjective mix quality.

## Boundary

Objective receipts support or reject candidate change claims; musical taste still requires listening review.

## Listening Prompts

- Does the supported candidate match the requested musical intent?
- Is the changed part better balanced in the proof window?
- Did the proof window contain the musical material being judged?
- Would another section or speaker profile change the listening decision?

## Caveats

- This packet does not prove subjective mix quality.
- A supported candidate proves objective receipts and guardrails only.
- Ranking orders review; it is not a taste score.
- Section-energy and loudness-style metrics are review aids, not proof that a candidate sounds better.
- Keep or apply the candidate only after listening review.
