00 :: command reference

A shell for useful questions.

This is a command-line metaphor, not an operating-system shell. It executes no arbitrary code. Commands only filter the checked-in catalog, choose a mission, scroll to a section, or copy a local work order.

01 :: /usr/share/man/eng25

Eighteen ways to make something work.

These are capability descriptions, not job titles or claims about named people. Open a man page to see inputs, outputs, proof, interfaces, common tools, and the qualification flag that should travel with the work.

04 :: proof.tar

Eight files travel with the thing.

The catalog becomes useful when every object, service, experiment, and handoff carries enough evidence to review, repair, repeat, or stop it. Popularity and engineering proof remain separate scores.

00

Mission

One sentence naming the user, useful result, operating place, and finish line.

01

Requirements

Each requirement has a source, owner, priority, and verification method.

02

Interfaces

Every material, energy, signal, person, authority, and handoff crossing is visible.

03

Assumptions

Loads, conditions, distances, availability, access, and unknowns are versioned—not smuggled in.

04

Build record

Drawing, bill of materials, process, supplier, configuration, and deviations travel with the thing.

05

Test record

Setup, calibration, raw data, pass/fail criteria, anomaly, correction, and retest remain inspectable.

06

Qualified gates

Licenses, competent people, permits, owners, operators, and site stewards are named before their authority is used.

07

Keep + close

Operator, maintenance interval, repair door, spares, stop rule, pack-out, restoration, and end-of-life path are assigned.
