Recovered historical or requested identity — documentary reconstruction; execution not rerun

TYPED BANGEL BINDING

- BeatDocument — grid, tempo, lanes and events
- AudioProfile — instrument and processing settings
- ProjectState — user controls and saved version
- PlaybackEvidence — timing and export observations

PRECONDITION

A musical sequence is created or edited.

SEMANTIC OBLIGATION

Preserve event timing and user controls, identify the actual synthesis/export path and distinguish browser support from future native plug-in work.

POSTCONDITION

Present the playable or exported result at the demonstrated capability level.

COMPILATION RULE

Elsa is the compiler. Use a declared Bangel grammar profile, independently admit the applicable JP representation and execute through Joanna only where that path is implemented. These fields are documentary contract notation, not parser-verified source. A shared .bangel extension does not prove grammar equivalence.

PROFILE RELATIONSHIP

Related identities: Bangel Studios; JP; Joanna Processing. Preserve each named contract and source status.

IMPLEMENTATION CHECK

Replay a fixed tempo and step pattern, then alter one step; compare deterministic event scheduling and state while keeping browser and native audio lanes distinct.

DISCOVERY NAMES

Physics Drum Sequencer; Drum Sequencer
These names aid search; current compiler naming remains Elsa.

SOURCE STATUS AND LIMITS

Recovered historical design and project records informed this documentary profile. Original conversations remain private; current implementation and reported historical tests were not rerun.
Recovered status: historical_report_not_fresh_verification.
Historical browser versions and downloadable build kits; native audio-host validation remains a separate requirement. Historical evidence has not been rerun in this discovery pass.

RECOVERED HISTORICAL CONTEXT
- Historical scope: Music/sequencing product family with JP-domain and deterministic runtime lineage.

PUBLIC SOURCE NOTE

Recovered historical design and project records informed this documentary profile. Original conversations remain private; current implementation and reported historical tests were not rerun.
