time-lapse-artifacts

Added 22 creator-confirmed, unchanged canonical Framelapse source fragments totaling 17,389,875,055 bytes and 3,391.699091 seconds of encoded playback.
Preserved five complete drawing sequences as ordered RecNN sets containing 2, 2, 6, 2, and 10 canonical fragments.
Increased active membership to 385 Standard plus 128 Pre-Standard records, or 513 total, without changing the 29-field schema or standard-2025-07-13 protocol ID.
Added a separate 27-row, 15-field dated relationship sidecar covering the 22 canonical fragments and five unchanged noncanonical InShot derivatives.
Stored the five derivatives under the nested provenance InShot/ directory; they remain outside both active metadata indexes, Viewer configurations, and active byte and duration totals.
Retained media-object-level record_id identity. This update does not add a global work_id, backfill historical rows, create a v3 release, or otherwise bump the dataset version.
Verified the 27 planned media additions, with no deletion or changed existing path, at immutable media-only PR revision bb4160045cae21a71bf360278549398dc9d2a028.
Verified all 27 relationship paths, SHA-256 values, byte sizes, Xet identities, canonical metadata joins, and exact root metadata bytes against immutable metadata-bearing PR revision 8a21015210c19936d3b18175ae3f4061ae1e5d8d. This validation does not assert Viewer settlement or merge status.

Unreleased — June 2026 recording-sequence filename correction

Corrected the canonical paths of 15 existing 30 × 40 in recordings dated June 18–30, 2026, to preserve the creator-confirmed continuous filename sequence Rec01 through Rec15.
Retained every media payload, stable record_id, Xet identity, byte size, technical field, and membership count; this is a filename correction, not a media addition or re-encoding.
Clarified that documented RecNN order may continue across finish dates and does not reset merely because the date changes.
The suffixes document recording order only; they do not by themselves assert separate drawings, sessions, or completion states.

Unreleased — August 22–23 recording-sequence ingestion

Added three creator-verified Standard recordings dated August 22–23, 2026, totaling 51,022,796,325 bytes and 3,895.390997 seconds of encoded playback.
Increased active membership to 363 Standard plus 128 Pre-Standard records without changing the 29-field schema or standard-2025-07-13 protocol ID.
Retained literal Rec01 through Rec03 filename suffixes for the continuing 14 × 17 in sequence; the suffixes do not independently claim an endpoint.
Verified direct visual continuity and drawing progression across all three recordings; integrity validation covers every complete video and audio stream.
Documented the creator-confirmed Rec03 ink change at approximately 00:04:59: Pelikan black before the visible refill handling and unmarked, unknown-brand black ink afterward. No replacement brand is inferred.
Rec03 produced one end-of-stream non-monotonic DTS warning from FFmpeg's null output during combined-stream validation. Source packet and decoded-frame timestamps at the tail remained strictly increasing, and both streams decoded.

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.
