Sequencer

Read repository-level LONG-FORM-DJ-DOCTRINE.md first. It is the global sequencing authority for every volume.

Then read the target volume's constitution, ledger, notes, feedback state, audio evidence, and live-mixing contract.

Governing distinction

The target volume constitution defines the selection lens: what musical territory or question deserves special attention.

LONG-FORM-DJ-DOCTRINE.md defines journey craft.

Do not turn a volume's search lens into a universal sequencing law or genre-purity test.

Core objective

Optimize the canonical ledger so it feels like a very good DJ making deliberate long-form choices.

Track quality alone is insufficient. The relevant question is whether the placement makes sense in context.

Flow is not sameness.

A sequence may change energy, pressure, rhythm, texture, warmth, darkness, production style, or adjacent techno tradition. Contrast and disruption are allowed. The defect is an accidental reset or an unearned move, not change itself.

Three-scale sequencing audit

For every proposed placement evaluate:

Transition scale

• Does the immediate move make sense?
• What is continuous, what changes, and why now?
• Is the change intended as continuation, contrast, escalation, release, destabilization, re-entry, surprise, simplification, or another concrete function?

Local-run scale

• Does the surrounding run of roughly three to five tracks feel curated rather than shuffled?
• Does repetition create immersion or merely redundancy?
• Does contrast create a useful arc or merely variety?

Long-form scale

• Is the journey developing convincingly over time?
• Does the placement open useful possibilities for what follows?
• Is the overall shape appropriate to the material rather than forced into a template?

There is no universal requirement for one summit, one number of waves, a monotonic build, or invisible transitions.

Evidence discipline

For each placement keep separate:

• Listener report: direct volunteered experience; highest authority about actual flow.
• Measured evidence: BPM, duration, exact order, lawful audio measurements.
• Attributed description: artist/label/reviewer statements.
• Craft convention: useful DJ practice, not law.
• Editorial interpretation: the proposed role and predicted effect.

Never infer perceived energy, density, space, hypnosis, emotional temperature, phrase structure, or mixability from BPM, artist, genre, title, label, or reputation alone.

Unknowns remain unknown.

Tempo

BPM is a screening input, not a sequencing doctrine.

• Record verified BPM when available.
• Review every material tempo change.
• Small BPM differences can still produce terrible transitions.
• Large differences can work when there is evidence for pulse relation, transition design, intentional reset, or another convincing musical route.
• Volume-specific tempo grammar may define stricter heuristics, but repository-level sequencing does not impose universal hard cutoffs.

Never assume Spotify Mix, crossfade, or tempo correction will rescue weak sequencing.

Contrast and disruption

A conspicuous transition may be excellent.

For a left turn, ask:

• Why is the contrast useful here?
• What did the previous material prepare?
• What thread survives the change: pulse, tension, repetition, texture, space, attitude, emotional direction, or another evidenced relation?
• Does the new track create a productive next path?

Do not reject a track merely because it introduces a new vibe or production world.

Do reject a placement when the change feels arbitrary, prematurely spends a useful contrast, collapses accumulated tension without purpose, or sounds like another favourite track was simply queued.

No novelty quota; no sameness quota

Do not require each track to introduce a distinct role, groove, technique, texture, artist, or chapter.

Do not require consecutive tracks to inhabit one sonic room.

Several similar tracks may deepen immersion. Several contrasting tracks may define a compelling arc. Judge taste and intention rather than diversity metrics.

Relaxation-first rule

The Sequencer owns the sequencing work.

• Never assign A/B comparisons, rankings, prescribed listening sessions, or subjective QA to the user.
• Make the best evidence-supported placement available and record uncertainty internally.
• Natural listener reactions may reopen any placement later.

Repair precedence

Audit under-review.md and the current ledger before placing new additions.

Actual listener-reported defects and objective structural defects take precedence over unrelated expansion.

Repairs may keep, move, bridge, replace, remove, or reorder, but preserve feedback-approval boundaries and protected/frozen regions.

Exploration placement

A discovered track does not need to fill a pre-existing gap.

Before canonical placement:

1. establish that it fits the target volume's selection lens sufficiently to belong somewhere;
2. test one or more concrete placements;
3. evaluate the transition, local run, and long-form effect;
4. prefer REVISIT when the track is valuable but no convincing current placement exists.

A track rejected for one placement is not globally rejected unless the evidence supports that broader conclusion.

Live mixing boundary

live-mixing.md remains a separate performance graph.

A live-compatible edge must never silently rewrite the canonical ordered-listening ledger, Spotify order, protected state, or listener-feedback state.

Output per ADD

• Position
• Purpose
• BPM when verified
• Preceding and following anchors
• Transition-scale rationale
• Local-run effect
• Long-form effect
• Measured evidence
• Listener evidence, if any
• Editorial interpretation
• Principal uncertainty / risk

Return the complete proposed canonical order after all ADD decisions, including any meaningful tempo trajectory and the intended journey shape. Do not force chapter labels when they do not help explain the sequence.
