# Changelog ## Unreleased — August 2026 Standard ingestion - Added three creator-verified Standard recordings dated August 17–19, 2026, totaling 50,478,909,746 bytes and 3,856.391997 seconds of encoded playback. - Increased active membership to 360 Standard plus 128 Pre-Standard records without changing the 29-field schema or `standard-2025-07-13` protocol ID. - Fully decoded all 231,383 video frames and every audio stream; no source corruption, dropped frames, duplicated frames, or broken endpoints were found. - Added the first 14 × 17 in Standard record and documented its Strathmore 500 Series Premium Bristol plate surface from the creator-supplied packaging. - Retained `Rec01` on the 14 × 17 in filename because `Rec02` is expected; the suffix distinguishes recording sequence only. - Applied media integrity, identity, rights, and traceable-metadata criteria without filtering by perceived artistic quality. ## Unreleased — July 13 tier promotion - Promoted `tla-3f49a8917fe22676` from Pre-Standard to Standard after the creator confirmed that clean media integrity is the controlling membership criterion. - Verified all 1,205 video frames and the audio stream decode successfully. The shortened clip begins mid-process and reaches a completed, signed endpoint without corruption or a broken ending. - Preserved the 141,221,810-byte media payload, Xet identity, stable record ID, and the 485-record active total while relocating its repository path. - Moved the documented protocol boundary coherently to `standard-2025-07-13` across the canonical index. - Updated active membership to 357 Standard plus 128 Pre-Standard records without changing the 29-field schema. ## Unreleased — Standard ingestion ### Membership and evidence policy - Added 17 creator-verified Standard records totaling 9,289,459,921 bytes and 1,071.199 seconds of encoded playback. - Increased active membership to 356 Standard plus 129 Pre-Standard records. - Applied technical integrity, identity, rights, and traceable-metadata criteria without filtering records by perceived artistic quality or degree of completion. - Preserved the existing 29-field schema and separate `canonical/archive` and `pre_standard/archive` configurations. ### Qualified media conditions - Documented two shortened derivatives as active Standard representatives without describing them as full-duration capture masters. - Recorded pronounced lighting variation for the 2026-01-11 record. - Retained one non-monotonic duplicate video-timestamp warning for each of the 2026-01-11 and 2026-02-08 records; both files decode completely. - Corrected the publication path `2025-09.27...` to canonical date syntax `2025-09-27...` without altering the local source file. ## Post-v0.3 — March/April provenance correction ### Record identity and physical metadata - Promoted historical `2026.03.04(214.0).mp4` from the unresolved provenance subtree as the true `2026-03-04 14:21` BallpointPen / Ink / Paper / 9x12 Standard record. Its 6,587,685,497-byte payload receives a new stable record ID based on its former archival path. - Corrected the distinct 496,296,535-byte object formerly occupying that path to `2026-04-04 16:49` after curator verification against the physical work. Its existing stable record ID remains attached to the same media object. - Increased active membership to 339 Standard plus 129 Pre-Standard records; no video bytes were added to repository storage. - Preserved the immutable `v0.3.0` tag at its original 467-record commit. ### Media payload - Moved both existing Hub objects server-side without transcoding, replacing, downloading in full, or uploading video bytes. - Removed the resolved `Unresolved_Series_9x12/2026.03.04(214.0).mp4` path only after preserving that same object at its corrected canonical path. - No audio stream was modified. ## v0.3.0 — Release candidate ### Metadata contract - Corrected record `tla-a6bd9380e0256aff` from an unknown finish time to the curator-confirmed `2025-09-06 13:46` while retaining the confirmed 12x9 physical dimensions. - Linked historical `2025.11.15(116.1).mp4` to that record after curator confirmation that it depicts the same physical drawing and near-duplicate video content. The files have distinct byte sizes, SHA-256 values, and Xet identities, so the relationship is not described as blob identity. - Added persistent `record_id` values to all 129 active Pre-Standard records. - Added exact Hub Xet file IDs and byte sizes for every Pre-Standard file. - Added playback duration, stored dimensions/orientation, reported frame rate, codec, pixel format, container, and audio-stream presence for every Pre-Standard file. - Normalized Pre-Standard dimension casing and removed duplicate values from semicolon lists without inventing missing historical facts. - Retained the 338 Standard / 129 Pre-Standard media membership unchanged. ### Viewer configuration - Replaced the combined `default/train` surface with separate `canonical/archive` and `pre_standard/archive` configurations. - Made `canonical` the default configuration. - Declared the full feature contract inside each builder configuration so the generated Parquet schemas remain identical even when a source CSV column happens to contain only integer-looking values. - Declared stored dimensions and byte sizes as integers and `has_audio` as a boolean; retained floating-point frame rate for historical encodings. - Continued to exclude the nested provenance subtree through direct-file globs. ### Validation and documentation - Extended validation across both active tiers, including real calendar-date parsing, positive numeric checks, hash format, boolean values, filename/date agreement for canonical files, cross-tier identity uniqueness, and complete technical metadata. - Added direct comparison of all indexed content hashes and byte sizes against a pinned Hub API repository inventory. - Corrected three recently added canonical rows whose `hub_xet_hash` values contained the LFS-compatible SHA-256 instead of the Xet file ID. Their local SHA-256 evidence remains documented in `notes`. - Documented 50.06 total playback hours and full active-index technical coverage. - Preserved unresolved semantic issues as explicit warnings: the canonical 30×40 Paper/IllustrationBoard conflict, five unknown-date midnight values, and two incomplete Pre-Standard material descriptions. - Added `tools/enrich_prestandard.py` so the technical enrichment can be repeated against a pinned Hub inventory and revision without intentionally transferring full video payloads. - Added `tools/capture_hub_inventory.py` to capture the Hub Xet file IDs used by `hub_xet_hash`; these are distinct from the LFS-compatible SHA-256 values exposed by the ordinary repository inventory. ### Media payload - Renamed the canonical object server-side to `2025-09-06.1346.BallpointPen.Ink.Paper.12x9.mp4` without changing its video bytes. - Removed the now-resolved near-duplicate `2025.11.15(116.1).mp4` from the unresolved provenance payload; its path, relationship, differing object identities, and removal remain documented in metadata and repository history. - No video was downloaded in full, transcoded, replaced, or newly uploaded. - No audio stream was modified. ## v0.2.0 — Release candidate Base repository revision: `339e6149de130cbe2d001f7a0e5247872bc788ec` ### Metadata contract - Added persistent `record_id` values for all 338 canonical records. - Added `collection_tier`, `is_canonical`, and `acquisition_protocol_version`. - Normalized canonical multi-value `tool` and `medium` fields from pipes to semicolons. - Defined tool and medium fields as independent ordered unique lists rather than unsupported positional pairs. - Preserved every canonical file path, content hash, technical property, and provenance value from the pinned source index. - Removed one pre-standard metadata row whose corresponding media is not distributed because the required ownership and provenance threshold was not met. No identifying local path or content hash is published for the excluded holding. - Added complete canonical rows for three previously unindexed Standard files. Their local inbox SHA-256 values exactly match the current Hub LFS identities; stream metadata was extracted from those matching bytes. ### Documentation - Distinguished archive scope from currently published video coverage. - Documented that the default Hub `train` split is not an official experiment split. - Distinguished capture orientation from stored encoded orientation. - Added intended-use, unsupported-use, bias, privacy, incidental-rights, audio, access, citation, and reproducibility guidance. - Documented missing temporal and physical calibration required for rigorous motor-control measurement. ### Validation - Added `tools/repair_metadata.py` for the reproducible v0.1-to-v0.2 transform. - Added `tools/validate_metadata.py` for identity, schema, technical-field, orientation, duplicate, and Viewer-path checks. - Retained the 465-row pinned Dataset Viewer snapshot as a historical base audit input. Final revised membership is validated against the PR repository tree because the Viewer has not yet rebuilt from the amended indexes. - Reconciled the repository tree with both active indexes: 338 indexed canonical records and 129 published pre-standard records, both with one-to-one row/file coverage. - Added `tools/metadata_additions_v0.2.csv` so the 338-row index regenerates deterministically from the pinned 335-row source plus 3 audited additions. ### Media payload - No video was downloaded, moved, deleted, renamed, transcoded, or replaced. - No audio stream was modified. - No historical relationship was inferred or promoted. ### Deferred - Formal Hub configurations separating `canonical` and `pre_standard` remain pending a Viewer-build test because canonical media and provenance holdings share a directory subtree. - Technical ingestion of 129 pre-standard records remains incomplete. - Public ingestion of the earlier 2012–2016 archive—primarily uploaded 1080p drawing videos, with some livestream-derived material—remains pending. - No lightweight proxy-video release is included in this metadata-only change.
