What Planisphere makes.

A customer starts with a workflow that may need to survive authorization, audit, litigation, or mission review. Planisphere records what happened, measures the tools involved, binds the behavior and controls to the relevant authorities, and produces a signed evidence record. A compliance team can recompute that record from the files alone and see whether it still matches.

Graph first. Harness second. Evidence third. The graph names the workflow and its sources; the harness runs the validation loop; the evidence record gives compliance a recomputable artifact instead of a trust-me memo.

The instrument carries its own integrity proof. Record contents can be recomputed locally; issuer trust can be pinned separately.

The instrument's evidence reduces to four artifact shapes inside the record and twelve standards counterparts the vocabulary tracks. Each card below names what binds, where, and how an evaluator picks it up.

The obvious mistake is to read this as a signing product. It is not. An e-signature service captures a human's consent over a document someone else authored — it records that you agreed, and binds your assent to a file it never had to understand. Planisphere does the opposite. It does not collect a signature over a document; it manufactures the definition in the first place.

The seal starts with measured system behavior. That behavior is compared against authority that was fixed before the audit ran, then the result is signed as a recomputable artifact. There is no counterparty whose consent is being recorded. There is no document being routed for assent. There is a measurement, a fixed standard, and a record an authorizing official, court, regulator, or counterparty can check from the inputs alone.

DocuSign captures consent over someone else's document. Planisphere produces a checked measurement against a fixed authority. The seal is not an agreement; it is a recomputable evidentiary record.

That is why the evidence check can be given away while the engine stays closed. Anyone can confirm a record in their own browser with zero core code — but confirming a record teaches no one how to manufacture one. See scope for how issued records are scoped.
