Tacit Tessera P R 1 001 CV · 1 · Professions · Records · collected by Strategic Agent · Specified The name is the address; the number is how the register writes it down.

Context envelope — scope and refuses, named as one object
What it covers. Covers one engineer's way of taking a site from investigation to a grading and foundation design: what is asked of a ground report, how a design is checked against it, what is written down at each stage and why. It is the practice's own method, written as a reference a successor's systems can be asked.
Where it stops. It refuses to stamp, seal or certify anything; a design decision stays with a licensed engineer. It refuses when the records do not support an answer, and it refuses any question that would expose a single client's job.
The envelope says what this entry was written for, and never what it is approved for. Its detail — the machine families, attachments, environment, materials, operating modes, jurisdiction, stated assumptions and known exclusions an edition is read against — is licensee-side and is not written here.

Status
Specified
Rights state
recorded — one of recorded, declared or documented, saying how far the rights in this entry have been put on the register. It sits beside the status word and is never folded into it.
Built from
The practice's own records — calculations, reports, specifications, job files and procedures — inventoried and mined into a reference, then ratified by the engineer whose practice it is. A client's own drawings and confidential material never feed the reference unless that client chooses to contribute.
How it is tested
The engineer writes the questions and seals them before the build. A pass means the answers are correct and name the record they came from, and it includes a question the records cannot answer.
Licence kinds offered
execution · learning · derivative — the kinds that may be licensed against this entry, each carrying a term, a field of use and a territory.
Conditions
None set. A contributor may put conditions on what is made of their skill — the field of use it may be run in, the territory, no use for surveillance, no use where a machine runs unattended, and a named use or house kept away from it — and a condition travels from here into the licence.

Event history
The number’s own record, in order: entries are appended and never rewritten, each is sealed into a chain, and nothing contested is removed. The register records; it does not decide. Every edition sealed so far sits below.

Its seal can be checked

The Card is sealed when the edition is frozen. Anyone holding the number can ask the register whether this Card is the one that was sealed, and whether this edition is still current.

Nothing is stored as a verdict. Every check is recomputed.
