Expose reviewed ingest timing through the current timing view
The September 19 ingest retains 12 device-filename starts, but its 14 recordings are outside the frozen Timing v2 snapshot and therefore display no starts. This change exposes those reviewed observations through the existing start fields while keeping two unavailable starts unknown.
A generated current timing view combines the unchanged 339-row Timing v2 packet with the 14 explicitly registered ingest observations. It covers 353 recordings: 175 filename-derived starts and 178 unknown starts. The exporter and validator bind retained observations to file identities, declared timezone evidence and pinned input receipts.
The metadata change is exactly 26 cells across 14 rows: 12 start values and 14 start-basis values. Frozen Timing v1/v2 packets, all other index values, the 35-column layout, work identities, finish labels, media paths and SHA256SUMS are preserved. Creation tags do not establish exact recording stops or drawing-active time.
Validation: 116 repository tests; exact reproduction of the new observation export; all six ingest source receipts and all 16 frozen Timing v2 source receipts; Timing v1 reconstruction; metadata, work identity and workflow-boundary checks; all 851 payload checksum entries; and header-only verification of 850 MP4 identities. No media bodies were downloaded or changed. Hosted Viewer settlement is checked separately after publication.
