Ephemera

The operator side of every comparison comes from files this project caught before they were replaced. Each cycle is hashed file by file into one Merkle root, the root is stamped into the Bitcoin blockchain through OpenTimestamps, and the manifest plus ten files chosen by the root itself are pushed into the Wayback Machine so an independent copy exists that this project does not control.

As of 2026-09-17 20:20 UTC: 57 cycles, 57 complete with roots, 57 anchored in Bitcoin, 22 with a defect in the independent copy. Source bytes archived: 1,310 GB across 645,325 files as served. Stored gzipped as 539 GB, of which 94 GB is on the poller's disk and 445 GB exists only in cold object storage. Cadence holds, meaning a set served longer than nine hours: 7. Poller heartbeat coverage over the last 24 hours: 99.2%. This project exists because SpaceX publishes the feed openly.

Method: built from each cycle's cycle.json, witness.json and ship.json in the poller's spool; coverage is the fraction of the last 24 h's minutes with a watcher heartbeat under 10 minutes old (D18); a cadence hold is a manifest first-seen gap over 9 h; source bytes are the responses as served, stored bytes are the gzipped archive objects the shipper recorded. Poller: home (Cape Town, residential; single poller until poller A exists).

A cycle still pulling at midnight is left out of that day's root and stays out. It keeps its own cycle root and its own OpenTimestamps proof, so nothing is unwitnessed, but it sits under no daily root.
