permanence contract

published coordinates do not drift.

Coordinate identity, renderer behavior, and source catalogs are versioned separately so shared musical places remain reproducible.

Coordinate identity

The everybeep:text:v1 scheme normalizes text with Unicode NFC and hashes a domain-separated UTF-8 payload with SHA-256. Existing addresses are opened only with an explicit @ prefix.

Immutable renderers

Stable routes and catalogs do not silently substitute new composition behavior. New behavior requires a new version or an explicitly documented pre-freeze migration.
