Commit the previously-untracked standard directories and catalog them in the
root README alongside proof:
- aac/ — communication cargo class: portable boards + a ten-level
offline-first cascade (Apache-2.0 code / CC-BY-4.0 spec).
- map/ — geospatial cargo class: range-requestable signed tilesets +
an F0–F4 fidelity cascade (Apache-2.0 code / CC-BY-4.0 spec).
- sandbox/— isolated, metered, attested execution across the heterogeneous
compute fabric (Apache-2.0 code / CC-BY-4.0 spec).
- jouleclaw-otel-authz, jouleclaw-trust — new jouleclaw reference crates.
Root README now lists aac, map, sandbox, and proof in the catalog, the tree,
and the contribution guide.

AAC lexicon (v1)
The controlled vocabulary of the AAC standard. Terms are stable; their IRIs live in v1.ttl under https://aac.transaction.science/vocab/v1#.
| Term | Meaning |
|---|---|
| Utterance | The cargo AAC carries: what a non-speaking person means to say, composed by selecting cells. |
| Board | A communication surface holding cells, of a given board type. The portable unit a voice travels as. |
| Board type | Grid | VisualScene | Keyboard | Hybrid | QuickAccess. A rendering + vocabulary-strategy marker. |
| Cell | A single selectable target at a fixed grid position, with content and an action. |
| Position | (row, col), 0-indexed. Assigned once and immutable for the life of the cell — the motor invariant. |
| Motor stability | The guarantee that cell positions never move except by explicit edit. Muscle memory is sacred. |
| Cell content | Symbol{id,label} | Text | Photo{ref,label} | Blank. Blank is an addressable reservation of geometry. |
| Cell action | What activation does: Speak | Navigate | Modifier | Backspace | Clear | Predict | SpeakAll | Buffer. |
| Symbol | A pictographic word referenced by source and id — not embedded pixels — so a board stays small and portable. |
| Access method | The physical channel of selection: DirectTouch | EyeGaze | HeadTracking | SwitchScan{n} | Joystick | Bci | PartialVoice | Pointer. |
| Motor profile | The user's physical capabilities (fine motor, sustained press, tremor, target size, reach, side) used to adapt targets and timing. |
| Scan mode | The switch-scanning pattern: Linear | RowColumn | Group | Block | inverse. |
| Dwell | Eye-gaze selection by sustained gaze, with visible progress feedback and a fatigue-bounded effective time. |
| Vocabulary level | Emergent | Transitional | Conventional | Literate — the user's stage, which selects the prediction tier. |
| Cascade | L0:Cache → L1:Symbol → L2:LocalPredict → … → L9:AdaptiveModel. The lowest level that closes a request wins. |
| Offline invariant | Exactly L0–L2 are offline-capable and carry 95%+ of communication; a network drop never silences a user. |
| Free invariant | No cascade level is gated behind payment at the protocol layer. A voice is not a metered good. |
| Interchange | Canonical export + one-directional ingest of existing boards. What goes in comes out; no lock-in. |
| Receipt | The per-operation energy record (measured + estimated µJ, provenance-tagged) — shown for transparency, never billed. |
| Provenance | HwShunt (hardware-measured) | ModelBased (calibrated model) | Estimator (constant). The honesty tag on every reading. |
| Steward | Transaction Science: publishes the spec, ships the reference, runs optional services (symbol libraries, voice banking, team coordination). Not the owner — AAC carries no token. |
