Module source_timing 

Exact, bounded source-timing evidence retained beside normalized source facts.

This contract is intentionally in-memory only. It does not widen the V1 raw-source facts or prediction wire contracts, and it never treats floating-point seconds or decimal frame rates as exact frame coordinates.

Structs

ExactSourceClipTimeRangeV1

Exact signed begin/end source-time coordinates for one animation clip.

ExactSourceClipTimingV1

Exact timing evidence for one retained source animation clip.

ExactSourceFramePeriodV1

Positive exact source-time units in one physical source frame.

ExactSourceTimeBasisV1

Positive exact source-time units in one second.

ExactSourceTimingObservationV1

One exact source timing value with orthogonal provenance and loader treatment.

ExactSourceTimingV1

Bounded exact source timing evidence from one successful loader parse.

ParserFrameRateProjectionV1

Exact binary64 payload exposed by a loader for a finite positive custom frame rate.

Enums

ExactSourceRangeSelectionV1

Parser-selected source time-span property pair.

ExactSourceTimingContractError

Invalid exact source timing value or attachment invariant.

ExactSourceTimingObservationStateV1

Availability of one exact source timing observation.

ExactSourceTimingUnavailableReasonV1

Why one exact source timing observation cannot be established.

SourceTimeDisplayProtocolV1

Source timecode display protocol.

SourceTimelineModeV1

Source timeline mode retained without converting it to decimal FPS.

Constants

EXACT_SOURCE_TIMING_V1_ID

Semantic identity of the exact in-memory source-timing vocabulary.
