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.
Validated immutable PR head e96889d48330567f26ba9e2097bceb07ff2bddbb. The diff is exactly three documentation files. The note contains the required creator-confirmed wording and exactly Rec01-Rec15 with 15 unique record IDs and paths matching pinned metadata at cd26daea10ecc1c609fd1e5b9531fec6bd3cdcaf. All 15 paths resolve in the pinned inventory; sizes and Xet identities match metadata, and LFS SHA-256 values match active SHA256SUMS. The PR-head inventory resolves all 806 MP4 files and validates all 807 checksum entries with zero missing targets, size mismatches, or content-identity mismatches. metadata.csv and SHA256SUMS are unchanged; active totals remain 673 Standard + 128 Pre-Standard = 801. Timing validation passes and the full regression suite passes 69/69. No media download, release, or tag.
Merged after exact three-file scope review, pinned 15-row metadata and inventory verification, full repository identity checks, and 69/69 passing tests.
