Trades & crafts — open, with nothing filed yet.
Trades and crafts is the division for work done at a bench, a station or a joint rather than from a machine's seat: welding, carpentry, electrical, plumbing and pipefitting, millwright work, masonry, machining, finishing. It is open, with nothing filed yet. Nothing is filed to this sector. What the Book holds today is filed to Construction and to Office.
What one entry would be.
Hands
One named person's way of doing one trade, held with that person's consent and asked for by name. The family here is the trade's own work, not a class of machine: welding, carpentry, electrical, plumbing and pipefitting, millwright and mechanic, masonry and concrete, machining and fabrication, painting and finishing.
Machine
A way of working taught to or loaded on a bench machine or a station, not a named person's. It is chosen by name before the work starts, it proposes, and it never authorizes.
Records
A reference built from a trade's own paper — job files and methods, drawings and specifications — that answers with named sources and refuses when the records do not support an answer.
The sector's own tables.
A family here is the trade being worked; a trade code is the two-letter field the work is done in. A welder on a civil job and one on a pipeline sit in the same family under different codes. Family 0 is a Set: a shelf, not a stew.

Both tables belong to this sector alone and come from the register. Opening a family or a trade is a decision of the register; a code is never renamed and never reused.
No number has been issued here; a tenth character is computed, never typed. Tacit Tessera T H 1 001 CV · 1 → TH1001CV18, a named welder's way of working on civil work, is an illustration, not a Book entry. T M 7 001 GN · 1 → TM7001GN1R, a taught way of working on a fabrication machine, is an illustration, not a Book entry. T R 1 001 EL · 1 → TR1001EL14, an electrical trade's own job files, is an illustration, not a Book entry.
Capture, track by track.
A Hands set here would come from a recorded session at the bench or the station. Consent is read at the moment of recording and never reaches back. It is four separate papers — to be recorded, to be held alongside others, to run under the person's own name, and to be used to train a model — each given and ended on its own.
Ending one is never a breach. It stops for new work at once; a job already underway finishes. There are two dates, never collapsed into one: the out-of-service date, when nothing runs it anywhere, and the true date, when every copy is gone.
What such a set may show has a ceiling: only what a person standing at the bench would see.
A Machine set would be a taught package, put together by the house that supplies it, loaded on one family of bench machine.
A Records set would be made the way one is made anywhere: records mining first, then Ratify. The converter turns a trade's own paper into a reference that answers with named sources and refuses when the records do not support an answer, and every output carries a receipt saying where it came from. Method statements are then drafted from that paper and the person accepts, amends or declines each one, each ratified statement authored and dated. Nobody is interviewed and nobody is recorded to build a Records set.
Most of a trade is not on paper.
A records reference captures the written-down-able kind of knowledge — the kind that would take too long to write out, the kind a person does without knowing it — and never the somatic kind, what the body does faster than words, or the collective kind. In a profession obliged to write things down, that line is generous.
Here it runs the other way. The decisive part of a trade is largely in the hands, which is why the Hands track exists for this sector and why a Records set built from a trade's paper is a smaller slice of what the trade knows. The paper says which grade is being bought.
The chain holds in this sector.
Steady Eddie and Strategic Agent require skill sets. Even Steven owns them. Tacit Tessera licenses them to OEMs and to AI.
Even Steven owns what is made of every skill, for the person or company it came from, and is the one paper a Source signs. You own your skill, always and forever. Tacit Tessera numbers each one, licenses it, counts every use, and lets anyone check it.
No house collects in Trades and crafts today, and none is named here until the sector takes its first entry. When one does, its mark is what the tile carries: a tile carries the collector's, never the owner's. Ownership is written on the Card instead.
Two kinds of licensee.
A licensee is an OEM — a maker of bench machines, a kit company, a shop — or an AI: a platform, an agent builder or a command centre that runs a Records reference. Both get a numbered, sealed edition, a count of every use, and a seal that can be checked. No skill set is sold to build a model from.
On the Hands track the shape is by the hour, under the person's name. A way of working is asked for by name and ended by name; the number sits beside that name and never in its place. It is chosen by name and never put together with another. There is no rank, no score and no paid placement. A record is never supplied to assess the person, to an insurer or to anyone else.
Several numbers can sit under one licence as a Mosaic, with family 0, and no member loses its own count, its own name or its own ending. The count is one signed row, serving as clearance, invoice and pay. A withdrawal on Records takes effect at the next serve.
Posted to the Source.
Two objects are made for a skill set at issue and posted to the Source: the plate, which is the tile made solid, with the number and the name standing proud of the face and the collector's mark stamped into it; and the card, the same marks at wallet size. Neither is a contract. A printed card cannot be recalled, so its authority comes from the verify address, recomputed at every lookup, and not from the plastic.
Open, with nothing filed yet.
Trades and crafts is open and empty. No number has been issued in it and no house has been named as its collector. What the Book holds today is Construction and Office.
No capture session has been recorded, no operator has been signed, nothing has been metered and nobody has been paid.
Where to go next
What is filed today is in the Tacit Tessera Book; any number can be checked at verify. For the person whose hands the work is in: in plain words.
