Function validateC2paManifestBoxSegment

validateC2paManifestBoxSegment(
    bytes: Uint8Array,
    lastManifestId: string | null,
    state?: ManifestBoxValidationState,
    options?: ManifestBoxValidationOptions,
): Promise<
    {
        nextManifestId: string
        | null;
        nextState: ManifestBoxValidationState;
        result: ManifestBoxValidationResult;
    },
>
Validates a C2PA manifest-box live stream segment.

Parses the C2PA manifest embedded in the segment and validates per §19.7.1 and §19.7.2. Recomputes the c2pa.hash.bmff.v3 content hash from the raw segment bytes and compares it against the expected hash in the manifest assertion. Checks live-video assertions (sequenceNumber, streamId, continuityMethod) and manifest-ID chain continuity. The live-video and BMFF hash fields of the result come only from assertions whose hash matches a claim reference. Check isValid before you use any field. A validator for an implementer-defined continuity method can be registered via ManifestBoxValidationOptions.

This function is pure — it does not access any external state. The caller is responsible for persisting nextManifestId and nextState between calls. A segment that fails verification, is on another stream, or does not move the sequence number forward returns the received lastManifestId and state unchanged. A segment that fails only the continuity check still updates them.
Parameters
- bytes: Uint8Array
  Raw segment bytes
- lastManifestId: string | null
  Manifest ID from the last segment that updated the state, or null for the first segment
- Optionalstate: ManifestBoxValidationState
  Optional state from the last segment that updated the state, for the streamId and sequenceNumber checks
- Optionaloptions: ManifestBoxValidationOptions
  Optional custom continuity method validator
Returns Promise<
    {
        nextManifestId: string
        | null;
        nextState: ManifestBoxValidationState;
        result: ManifestBoxValidationResult;
    },
>
Validation result, the manifest ID, and state to persist for the next call
Example
```
it('returns isValid=false with errorCodes for empty bytes', async () => {
	const { result, nextManifestId } = await validateC2paManifestBoxSegment(
		new Uint8Array(0),
		null,
	)

	strictEqual(result.isValid, false)
	strictEqual(result.errorCodes.length > 0, true)
	strictEqual(result.manifest, null)
	strictEqual(nextManifestId, null)
})
```
