Changelog

[1.0.0-draft.1] - Working Draft

  • Add optional marker roles with backward-compatible default behavior of ["cue"] when omitted.
  • Distinguish playback cue markers from quantize timing markers.
  • Add optional marker quantize metadata using gridIndex plus phase.
  • Expand transport.quantizeUnit to support half-beat, quarter-beat, and eighth-beat.
  • Clarify that media.primaryVideo.alpha is the authoritative playback alpha flag.
  • Clarify that marker frames always reference baked primaryVideo frame space.
  • Make transport.defaultSpeed optional in schema; readers must assume 1.0 when omitted.
  • Add explicit default for transport.quantizeUnit: readers must treat omitted value as none.
  • Define semantics for each transport.quantizeUnit value, including marker (snap to nearest marker frame in frame order).
  • Mark proxy/ and analysis/ as reserved paths with no normative definition in v1; remove proxies from core schema.
  • Clarify easing as an advisory hint for entry state adoption on trigger/teleport, not a frame-stepping law.
  • Document that role-dependent field constraints must be enforced by code-level validators, not JSON Schema.
  • Require readers to derive frame order from frame values and not rely on marker array order.
