# GM SongBench: Mr. White

> This is an AI-facing artifact packet. Do not treat it as an edit order. Use JSON as source of truth. Human canon decisions override analysis.

GM SongBench turns audio into structured musical evidence. It does not replace taste; it records evidence around taste so later AI readers can reason about what the ear heard.

## Human Ear Seed

- Kerry read: Mr. White is locked in Captain White slot 14; this packet records read-only album-facing evidence.
- Diana read: -
- Album role: Closing nameplate track: the album lands on Captain White as embodied myth and local legend.
- Known concern: No localized defect is asserted by this packet. Machine diagnostics are evidence prompts only; human listening controls.
- Why this track matters: Closing nameplate track: the album lands on Captain White as embodied myth and local legend.

What makes it land:

- Closing nameplate track: the album lands on Captain White as embodied myth and local legend.
- Its SongBench packet documents measured audio evidence around the locked album placement without changing canon.
- Its lyric-section map is navigational scaffolding until hand-aligned lyric/audio sync exists.

## AI Ear Translation

- Human/canon call: Mr. White is locked in Captain White slot 14; this packet records read-only album-facing evidence.
- Album role: Closing nameplate track: the album lands on Captain White as embodied myth and local legend.
- The audio packet should help later reviewers compare waveform energy, section shape, and lyric thesis without depending only on memory.
- No localized defect is flagged in this read-only packet; treat this as album anatomy, not an edit order.

## Evidence Balance

### Evidence the song has a clear album job

- locked Captain White slot 14
- Closing nameplate track: the album lands on Captain White as embodied myth and local legend.
- included in the current Captain White sequence with audio and lyrics present

### Evidence suggesting caution

- lyric timing is proportional only and should not be treated as verified sync
- machine diagnostics cannot judge vocal confidence, pocket, performance magic, or final taste value
- this is a read-only analysis packet and must not be treated as a request to edit audio, lyrics, title, or order

### Human listening should verify

- the hook and vocal delivery support the stated album role
- any machine-flagged quiet windows are structure evidence, not automatic edit points
- the track feels like a song first and archive/provenance second

## Field Source Classification

- `audio, analysis.dynamics, analysis.tempo_estimate, analysis.energy_regions_8s, analysis.quiet_windows, visual_summary_words`: audio_measured (derived_rough) - Extends AI hearing with measured audio proxies.
- `diagnostics.chorus_landing`: audio_measured_plus_section_scaffolding (rough_rms_proxy) - Uses approximate lyric sections plus RMS envelope; useful for questions, not verdicts.
- `lyric_section_map, memorable_line_anchors`: lyric_structural_scaffolding (proportional_estimate) - Helps navigation but is not verified audio alignment.
- `canon_control, human_ear_seed, evidence_clear_album_job, ai_ear_translation`: human_canon_scaffolding (curation_context) - Anchors machine evidence to Kerry/canon context.

## Memorable Line Anchors

- first_thesis_line: Mr. White sat third row back (00:00.000-00:32.164)
- hook_line: Son, let me give you wings (01:04.328-01:36.492)
- turn_line: Years before the red lights found him (03:53.189-04:25.353)
- final_identity_line: Let me give you wings (04:57.517-05:21.640)

## Diagnostics

### Chorus Landing

Band legend:

- within_noise: abs(delta) < 0.75 - RMS difference is too small to treat as a meaningful lift/drop proxy.
- modest_lift: 0.75 <= delta < 2.0 - RMS proxy suggests a small lift into the chorus.
- notable_lift: delta >= 2.0 - RMS proxy suggests a clear energy lift into the chorus.
- modest_drop: -2.0 < delta <= -0.75 - RMS proxy suggests a small drop entering the section.
- notable_drop_or_fade: delta <= -2.0 - RMS proxy suggests a clear drop, often requiring fade/context caveats.

- Chorus (01:04.328-01:36.492): hook `Son, let me give you wings`, energy_lift_band=within_noise, rough_db=-0.6, confidence=rough_rms_proxy; Banded RMS change near the chorus/drop landing; does not judge vocal confidence or hook feel.
- Chorus (02:56.902-03:29.066): hook `Son, let me give you wings`, energy_lift_band=within_noise, rough_db=0.1, confidence=rough_rms_proxy; Banded RMS change near the chorus/drop landing; does not judge vocal confidence or hook feel.
- Post-Chorus (03:29.066-03:53.189): hook `Wings`, energy_lift_band=within_noise, rough_db=-0.4, confidence=rough_rms_proxy; Banded RMS change near the chorus/drop landing; does not judge vocal confidence or hook feel.
- Final Chorus (04:25.353-04:57.517): hook `Son, let me give you wings`, energy_lift_band=modest_lift, rough_db=0.8, confidence=rough_rms_proxy; Banded RMS change near the chorus/drop landing; does not judge vocal confidence or hook feel. Caveat: This window overlaps the ending fade; do not read a negative band as a weak-chorus verdict.

### Groove / Pocket

- Rough tempo and dynamics only; pocket is a human-ear judgment until beat-grid analysis exists.
- Tempo proxy BPM: 126

### Section Drag

- Flags long proportional sections only; it cannot decide whether a bridge or outro has earned its length.

### Label Infection Scan

- Status: no_obvious_label_infection_detected
- Known artifact class: sung stage direction / speaker label / call-response label infection

## Visual Summary In Words

- Loudest 8-second region by RMS proxy: 00:48.000-00:56.000 at -13.371 dBFS.
- Quietest 8-second region by RMS proxy: 05:20.000-05:21.640 at -42.363 dBFS.
- Waveform and spectrogram images should be read as supporting evidence for section density, energy ramps, and unusual transients, not as final taste judgments.

## Current Edit Triage

- Current action: no edit requested for this track.
- Use quiet_windows as future splice/crop candidate evidence only after human listening confirms a local defect.
- Preserve title, CW slot 14, audio file, and lyric file unless Kerry explicitly reopens the track.
