> 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.

## Evidence Balance

### Evidence the song has a clear album job

- The source ledger lists Spend It Well in GlitchMob Time slot 6.
- source status: source-verified
- source audio and lyric files are present and hashed

### Evidence suggesting caution

- no human listening or subjective album-role evaluation was performed for this packet
- 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

- hook, vocal delivery, groove, and artistic album role
- any machine-flagged quiet windows are structure evidence, not automatic edit points
- performance and localized artifacts before making taste or edit judgments

## 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`: source_ledger_scaffolding (curation_context) - Records source-ledger placement without a human listening judgment.

## 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 (00:49.014-01:25.775): hook `Time is the money`, energy_lift_band=notable_lift, rough_db=2.9, confidence=rough_rms_proxy; Banded RMS change near the chorus/drop landing; does not judge vocal confidence or hook feel.
- Chorus (02:14.789-02:47.465): hook `Time is the money`, energy_lift_band=notable_lift, rough_db=2.9, confidence=rough_rms_proxy; Banded RMS change near the chorus/drop landing; does not judge vocal confidence or hook feel.
- Final Chorus (04:00.986-04:33.662): hook `Time is the money`, 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. 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: 88

### 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: 04:40.000-04:48.000 at -9.546 dBFS.
- Quietest 8-second region by RMS proxy: 00:00.000-00:08.000 at -26.002 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, GMT slot 06, audio file, and lyric file unless Kerry explicitly reopens the track.
