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: Pontifex ex Machina is locked in AI Psychosis slot 11; this packet records read-only album-facing evidence.
- Diana read: -
- Album role: Institutional-metaphysics track: the machine-priest counterpart turns fake sacrament into apparatus, office, and doctrine.
- Known concern: No localized defect is asserted by this packet. Machine diagnostics are evidence prompts only; human listening controls.
- Why this track matters: Institutional-metaphysics track: the machine-priest counterpart turns fake sacrament into apparatus, office, and doctrine.

What makes it land:

- Institutional-metaphysics track: the machine-priest counterpart turns fake sacrament into apparatus, office, and doctrine.
- 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.

- 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 AI Psychosis slot 11
- Institutional-metaphysics track: the machine-priest counterpart turns fake sacrament into apparatus, office, and doctrine.
- included in the current AI Psychosis 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: Silentium (00:00.000-00:14.913)
- hook_line: Ad concilium (00:52.194-01:22.019)
- turn_line: Memoria transferatur (02:29.125-02:51.494)
- final_identity_line: You called me Holy Father. (02:51.494-03:39.960)

## 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 — full dance drop, choir enormous (00:52.194-01:22.019): hook `Ad concilium`, energy_lift_band=notable_lift, rough_db=4.5, confidence=rough_rms_proxy; Banded RMS change near the chorus/drop landing; does not judge vocal confidence or hook feel.
- Chorus — bigger, more ecstatic (01:59.300-02:29.125): hook `Ad concilium`, energy_lift_band=modest_drop, rough_db=-0.8, confidence=rough_rms_proxy; Banded RMS change near the chorus/drop landing; does not judge vocal confidence or hook feel.

### Groove / Pocket

- Rough tempo and dynamics only; pocket is a human-ear judgment until beat-grid analysis exists.
- Tempo proxy BPM: 114

### 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: 00:56.000-01:04.000 at -10.057 dBFS.
- Quietest 8-second region by RMS proxy: 03:36.000-03:39.960 at -72.612 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, AIP slot 11, audio file, and lyric file unless Kerry explicitly reopens the track.
