Scope

Ingest 178 unchanged-source MP4 recordings as 21 creator-confirmed complete
drawing sequences dated 2026-09-21 through 2026-09-26. The supplied finish
labels describe each completed drawing/group, not the individual stop time of
every recording.

This PR is rooted at immutable dataset revision
22f6f36bed668f090c260ffadd7b9e8f60e0fe79.

Evidence and identity

• Preserve the exact 178 source byte streams; require distinct SHA-256 values,
  stable pre/post source state, complete demux agreement, 178/178 error-checked
  full decodes, and 534/534 start-middle-end sampled decodes before upload.
• Preserve the existing 35-field canonical schema, deterministic tla-...
  record IDs, and deterministic tlaw-... work IDs.
• Add six dated provenance packets (2026-09-21 through 2026-09-26) using
  the established 15-field relationship sidecar, plus revision-bound timing
  observations that keep per-file clocks separate from drawing finish labels.
• Retain 2026.Pencil.Graphite.BallpointPen.Ink.9x12.mp4 verbatim. The owner
  explicitly resolved it as position 18 in the
  2026-09-25.1825.Pencil.Graphite.FountainPen.Ink.Paper.9x12 drawing. The
  correction note records the conflicting filename evidence without inferring
  per-record materials or silently repairing the source name.

Expected resulting archive state

• 923 Standard records and 128 Pre-Standard records.
• 401 active work IDs and 923 positive canonical record links.
• 1,057 checksum-covered LFS payloads: 1,056 MP4s plus the existing provenance
  ZIP.
• 559 rows in the living Standard timing/current-individual views; frozen
  historical timing and release manifests remain unchanged.

Safety boundary

The upload is sequential and restart-safe. Every public commit is parent-pinned,
path-allowlisted, byte-verified, and confined to this draft PR. Merge remains a
separate guarded action requiring the exact reviewed head, all-path inventory,
no conflicts, no deletions, unchanged historical identities, and a passing
local validation packet. Source recordings are not moved, renamed, deleted,
recycled, or dehydrated.
