# GM SongBench: Double Tap

> 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.

## Canonical Placement

- Album: Indulgence (`indulgence`)
- Track number: 2
- Status: unlocked
- Audio: `/assets/albums/indulgence/audio/double-tap.mp3`
- Lyrics: `/assets/albums/indulgence/lyrics/double-tap.txt`
- Packet type: `anatomy_provenance_packet`
- Canon status: `unlocked_public_bonus_track`
- Edit authority: SongBench is not an edit order. It can advise; Kerry's explicit canon instruction controls.

## Human Ear Seed

- Kerry read: Double Tap is released in Indulgence slot 02 and publicly credited to Nova.
- Diana read: -
- Album role: reciprocal-forgiveness track; shared mischief, mirrored responsibility, and mercy complete a loop without a judge
- Known concern: No localized defect is asserted. Preserve the song's compact comic logic: mutual implication turns into mutual forgiveness rather than trial or scorekeeping.
- Why this track matters: It moves Indulgence from one person's practical mercy into a two-person loop where responsibility and forgiveness travel in both directions.

What makes it land:

- The double-tap hook makes reciprocity audible: one gesture is answered by another.
- Fingerprints, matches, maps, reflections, and the repeated loop keep shared responsibility concrete rather than abstract.
- The bridge rejects enemy and cage roles before the final chorus converts the conflict into movement.

## AI Ear Translation

- Human/canon call: Double Tap is released in Indulgence slot 02 and publicly credited to Nova.
- Album role: reciprocal-forgiveness track; shared mischief, mirrored responsibility, and mercy complete a loop without a judge
- 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

- released Indulgence slot 02
- publicly credited to Nova
- extends the album's mercy theme from individual action to mutual release
- audio and complete lyrics are present

### Evidence suggesting caution

- lyric timing is proportional only and is not verified synchronization
- SongBench cannot decide whether the pocket, comedy, or repetition lands; human listening controls
- do not infer private historical contribution data from this public packet

### Human listening should verify

- the repeated hook feels reciprocal rather than merely repetitive
- the comic details preserve tenderness without erasing responsibility
- the bridge creates enough contrast before the final chorus returns

## 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

- hook_line: Double tap / I forgive you / You forgive back (proportional estimate)
- shared_responsibility: Mine look like yours / And yours look true (proportional estimate)
- mercy_turn: No judge above us / No debt below (proportional estimate)
- boundary_line: You are not my enemy / I am not your cage (proportional estimate)

## Lyric Section Map

Timing confidence: `proportional_estimate`. These ranges are rough proportional anchors until hand-aligned timestamps exist.

## 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 (00:45.749-01:02.385): hook `Double tap`, energy_lift_band=within_noise, rough_db=-0.3, confidence=rough_rms_proxy; Banded RMS change near the chorus/drop landing; does not judge vocal confidence or hook feel.
- Chorus (01:35.656-01:52.292): hook `Double tap`, energy_lift_band=modest_drop, rough_db=-0.9, confidence=rough_rms_proxy; Banded RMS change near the chorus/drop landing; does not judge vocal confidence or hook feel.
- Final Chorus (02:08.928-02:25.564): hook `Double tap`, energy_lift_band=within_noise, rough_db=0.7, 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: 141

### 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 -12.165 dBFS.
- Quietest 8-second region by RMS proxy: 02:40.000-02:42.200 at -51.432 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, IND slot 02, audio file, and lyric file unless Kerry explicitly reopens the track.
