Reference · Documentation Field notes for the careful traveller Plate 05 · MMXXVI

Field notes.

Documentation is not after the journey. It is alongside it — read it slowly. Three products, three short shelves: each one a careful description of how a tool moves, what it records, and what it will not do without your say-so.

The shelf, not the manual.

Each entry is a short, dated note. Long enough to be useful; short enough to be read before the next meeting. Tread carefully — the notes are versioned.

/ 02ConceptsRead these first

Concepts that travel across the three tools.

A handful of ideas show up in every product — the same chain of logic, the same canonical language. Read these first.

K.01

The hash-chained log

Every product carries an append-only, hash-chained audit. Identical payloads produce identical hashes under RFC 8785 canonical JSON — across Rust, Python, and WASM.

K.02

Glass-box findings

Every finding cites the rule it fired on, the input that triggered it, and the confidence assigned. No black-box verdicts.

K.03

Principal & RBAC

Identity is a principal with scopes; access is a role with permissions; everything is logged with the principal that performed the action.

K.04

Policy as artefact

Disclosure, redaction, and classification rules are versioned, signed policy bundles — not application code. The bundle is itself audited.

K.05

Modal verbs & obligations

Across Redline and Fieldbook, obligations are classified by modal verb — shall, must, should, may — with statutory basis and confidence carried along.

K.06

Step-up events

Privileged actions — first-of-session reads, bulk exports, overrides, reclassification — require a second factor and emit a dedicated audit event.

Read carefully. Then begin.
