WHEELPRINTS - SOURCE NOTES
Captured: 2026-10-30T19:34:56.085015Z
Purpose: three project-API-reported Sepolia settlements for a recorded-data art beta. These are snapshots, not a live feed and not mainnet assets.

All three returned HTTP 200 and status available. The settlements payload was generated at 2026-10-30T19:34:04.987Z.

ROUND BOUNDS
roundStart and roundEnd are inclusive round IDs. startAt is inclusive; endAt is exclusive. Each selected period is exactly one round. The API record's previousSettledThroughRound is exclusive, so our first included round = that value + 1.
Round 1 starts at genesis, as documented at https://docs.squeekchain.com/developers/core/ (Types; Integrator patterns). The current API reports genesisTimestamp 1793022600 (2026-10-26T13:50:00Z), roundDuration 600 seconds.
startAt = genesis + (roundStart - 1) * 600.
endAt = genesis + roundEnd * 600.
These are derived round times, not transaction times. Settlement may occur later. The unchanged source records, including blockTimestamp, are retained in research/period-evidence.json.

SELECTED INTERVALS (UTC)
Drift: round 539, 2026-10-30T07:30:00Z to 2026-10-30T07:40:00Z, 199 work, 17 blocks; tx 0xae5fab9c7d4ec6eff15a8e9fb9657345a6485b8dd7f6d96b0d675f651aa6e36c
Pulse: round 517, 2026-10-30T03:50:00Z to 2026-10-30T04:00:00Z, 336 work, 27 blocks; tx 0x638ed63c96cc81f4452e697ada7ea0df332ccb745df6b73c86a596e2a1c72f82
Surge: round 499, 2026-10-30T00:50:00Z to 2026-10-30T01:00:00Z, 615 work, 51 blocks; tx 0xf7f8c0db49774700c85986a976faeefd813ea61eaa4ffe0e4d1a2b8b05eab487
The titles Drift, Pulse and Surge are original editorial labels. They do not assert a hamster mood or continuous running speed. Work and completed-block counts are copied from workAdded and completedBlockCount for the SAME source transaction; they are not interpolated.

RECORDED-VALUE CHECKS — OCTOBER 31, 2026
All three archived records were checked against Blockscout Sepolia transaction/event data and PublicNode Core historical reads. The round bounds, accepted work, completed-block counts, cumulative endpoints, source transactions and source blocks matched. Core configuration() also matched the stream ID, genesis and 600-second round duration. See chain-verification.json for provider URLs, checkedAt timestamps, source block hashes, log indexes and exact historical endpoints.
Historical reads were pinned to Ethereum block 12036964, hash 0xaa652d7142726304d85554bf6f1992475f800aa57ef9ada51c15a8ddf2ab02f8. Completed blocks were independently calculated as floor(end.cumulativeBlockUnits / 1000000000) minus floor(start.cumulativeBlockUnits / 1000000000).

VERIFICATION LIMITS
These public-provider checks corroborate recorded Ethereum values. They do not establish physical sensor truth, official endorsement, canonical project support or smart-contract security. No independently operated node or consensus audit is claimed. PublicNode did not return two older transaction receipts; successful Blockscout transaction/event responses and PublicNode historical views supplied the bounded corroboration for those records.
The original API confirmationStatus and release label remain project-reported metadata. The sourceURL intentionally identifies the API that supplied the original snapshot; independent-check sources are recorded separately in chain-verification.json.
The documented older Core v3/Mining v6 manifest differs from the API-reported current release (Core v3/Mining v9/Staking v2). Do not use these addresses or snapshots to prepare transactions. Obtain and verify the canonical current deployment and ABI first.

REPRODUCIBILITY AND REPLAY
periods.json and periods.js contain identical data; periods.js assigns window.WHEELPRINTS_DATA for offline file loading. All work and cumulative values remain decimal strings. blocks is an integer. Raw API replies and HTTP capture metadata are retained under research/, with selected records in period-evidence.json and raw-file SHA-256 checksums in SHA256SUMS.txt.
The public settlements endpoint is a moving 24-hour window with a limited recent-settlement list. A future refetch may omit these exact records; preserve the snapshots for replay. CapturedAt is our UTC retrieval time, while generatedAt is the API's generation time. Rendering determinism also requires a fixed artwork algorithm/version and stable seed inputs; a reproducible image does not independently authenticate its source.
API-driven SVG rendering is offchain artwork informed by reported settled data. This prototype does not mint, store an onchain art commitment, require a wallet or sign anything.
