Cubed Solve Captures (`cubed-data-v1`)

35 self-recorded captures of a GAN 12 ui Bluetooth smart cube being solved: 3.15 GB of portrait 1080×1920 H.264 video at about 120 fps with no audio. Every capture includes the cube's BLE move log and a replay-checked scramble record; 29 also include phone IMU samples. The corpus exists for camera-only decode research — reconstructing a solve from ordinary phone video — and is the input set for Cubed Core's historical Benchmark v0 evaluation. The corpus itself has no assigned train/validation/test split.

Suites

suite	captures	what it is
`cs`	25	Complete solves. Full BLE + IMU. Video covers the whole solve on 24 of 25.
`gt`	6	Research captures (gt17–gt22). Video ends before the solve's final move on five of six. Video + BLE + scramble record; no IMU.
`gtD`	4	On-camera scramble from a verified solved start (gtD2–gtD5). The scramble itself is filmed. Full BLE + IMU.

The cs count includes the solve-only gtD1 Demo capture. The per-capture scramble.json records that all 35 BLE move logs replay from their stated starting state to solved under two cube implementations. The per-move facelets strings embedded in a log are the cube's own periodic state broadcast and can lag the move stream, so they are not the replay source of truth — use the scramble/start state plus the move tokens.

Layout and fields

One directory per capture under captures/<capture_id>/.

file	captures	contents
`video.mp4`	35	Stream-copied from source: bitstream untouched, audio removed, container metadata stripped.
`scramble.json`	35	Scramble in standard notation, derived start state, replay-verification and truncation status.
`rights_record.json`	35	Per-artifact rights binding by byte count and SHA-256.
`cube_session.json`	35	BLE move log: moves, facelet states, quaternions.
`imu.json`	29	Phone IMU orientation samples.
`app_cube_session.json`	15	App-side BLE log, verified move-identical to `cube_session.json`.
`capture_manifest.json`	14	Capture-app manifest.
`clip_ble_ground_truth.json`	1	Frame-indexed BLE ground truth (gtD1 only).

dataset/manifest.json is the authoritative inventory for the 199 corpus artifacts. readiness-report.json is the generated validation receipt for that inventory. The benchmark/ directory is a separately published annex and is not counted by that receipt's artifact_count or benchmark_v0_included fields. SHA256SUMS covers every tracked file except itself.

Each capture artifact declares its schema in dataset/manifest.json. The benchmark manifest and split reports also have schemas in Cubed Core; the smaller score and hash tables are receipts rather than schema-bearing API documents.

No calibration or camera-metadata artifact ships per capture. The corpus was recorded with one cube and one camera setup family, and decode uses the single shared six-colour calibration (calibration_gan12.json) distributed as a cubed-core release asset. That calibration was measured under one lighting condition while the corpus spans three recording cohorts — treat colour evidence away from the gtD1 session accordingly.

Benchmark v0 results

These are the named historical Benchmark v0 evaluation results on this corpus. Per-row tables, per-capture narratives and hash-bound receipts are under benchmark/. They record the configuration used at the time and are not claims about the current Cubed Core profile.

suite	metric	result
gt suite	reach-LL	5 / 6
gtD1s	reach-solved	1 / 1
cs suite	reach-LL	4 / 24

gt19 is reported informationally and excluded from the tallies: it was used to train an upstream verifier, so any result on it is contaminated.

Reach-LL asks whether the raw predicted state path reaches last-layer onset with the correct pre-last-layer state, up to whole-cube orientation. These figures come from the evaluation lane, which supplies a ground-truth terminal; the productized camera-only path is a separate lane with its own contract and is not tabulated.

Intended use

This corpus is for camera-only cube-decode research: reconstructing a solve from ordinary phone video, with the cube's own BLE move log available as ground truth. It is also the input set for Cubed Core's Benchmark v0. It is a corpus, not a benchmark — no train/validation/test split is assigned here, and results measured on it are within-solver, within-setup findings.

Decoding requires a CUDA host. The pipeline, runner and v1.0.0 configuration live in cubed-core. See the Decode tutorial and config/decode-runtime-v1.json. At v1.0.0, local_camera_v1 has CFG_HASH 2429939321 and canonical_eval_reference has CFG_HASH 3894620704. Benchmark v0 used the older identities preserved in its report; rerunning with v1.0.0 is a new run.

Privacy

All captures were self-recorded by the dataset author solving a GAN 12 ui smart cube filmed with an iPhone, using maintainer capture tooling that is not included in Cubed Core v1.0.0. No other person appears in or contributed to the recordings. The videos have no audio track and no container metadata. Hands and the cube are the primary subject; some frames also show the author's clothing, lower face and room background. The footage is partially identifiable and is not de-identified.

The published sensor payloads use relative frame or millisecond indices. Some derivation records retain source filenames, recording timestamps and relative research-note references; they contain no absolute filesystem paths, device serial numbers or hostnames. Rights records intentionally retain the public attribution, reviewer handle and rights-review timestamp.

Limitations

One solver, one cube, one camera setup family. These captures cannot establish generalization across users, cameras, cubes, grips or lighting.
Video ends before the recorded solve's final move on six captures (five of gt17–gt22, plus gtD4); each capture's scramble.json records its own truncation status. The BLE log is complete regardless.
No per-capture colour calibration ships; decode uses one shared calibration measured under a single lighting condition across a corpus spanning three recording cohorts.
The Benchmark v0 figures above come from the evaluation lane, which supplies a ground-truth terminal. They are not camera-only results.
