Document June 2026 historical file relationship

Add one revision-pinned historical provenance note for Tim's confirmation that the 15 June 18–30, 2026 Rec01–Rec15 files document the same physical drawing and that RecNN establishes file order. The note includes the exact 15 record IDs and paths, and states that the supplied screenshot identifies the files but is not independent proof of their contents.

This is a three-file documentation-only change. It does not alter media, paths, record IDs, metadata.csv, SHA256SUMS, dates, blank times or provenance fields, acquisition protocols, relationship packets, cohort counts, releases, or tags. Internal recording and session boundaries, per-file counts, raw-source status, uninterrupted capture, shared finish timing, and overall completeness remain unasserted.

+- Added a revision-pinned provenance note recording Tim's confirmation that the
+  15 existing June 18–30, 2026 `FountainPen.Ink.IllustrationBoard.30x40`
+  `Rec01`-`Rec15` files document one physical drawing and that `RecNN`
+  establishes file order.
+- Preserved all active media, paths, record IDs, metadata, checksums,
+  `UnknownTime` values, blank provenance fields, and protocol assignments. The
+  note does not assert internal recording or session boundaries, per-file
+  recording counts, overall completeness, shared finish timing, raw-source
+  status, uninterrupted capture, a global `work_id`, or new cohort membership.
+
 ### September 1 finish-time correction
 
 - Corrected the creator-supplied finish label for the complete 12-fragment

+This note records a creator-confirmed relationship among 15 existing canonical
+video objects. It is bound to the repository state inspected at source revision
+[`cd26daea10ecc1c609fd1e5b9531fec6bd3cdcaf`](https://huggingface.co/datasets/maxwellinked/time-lapse-artifacts/commit/cd26daea10ecc1c609fd1e5b9531fec6bd3cdcaf)

+At that revision, the 15 paths below resolve to exactly 15 unique persistent
+`record_id` values and exactly `Rec01` through `Rec15`.
+
+> These 15 files document one physical drawing. Rec01–Rec15 establishes file
+> order. A file may contain multiple recordings. Internal recording and session
+> boundaries and overall completeness are not asserted.
+
+Tim's confirmation in the companion conversation is the evidence for the
+same-drawing relationship and file order. The supplied screenshot identifies
+the files; it is not independent proof of their contents. Tim described a
+possible range of 2–10 recordings within a file, but exact per-file recording
+counts have not been established.
