Module readouts 

Readout engine — see docs/SRD/63_status_readouts.md.

The engine provides:

• The Readout trait + Lod / ContentMode enums.
• The minimum ReadoutContext surface needed by the phase_outcome built-in. Methods that future built-ins will need are added in later pushes as needed.
• One built-in: builtins::phase_outcome at Lod::Labeled / ContentMode::Value. Other LODs and the explanation-overlay mode render zero bytes until later pushes fill them in.
• A small static registry to look up readouts by name.

Lives as a module under nmbrs-runtime rather than its own crate: the trait surface and built-ins read from data sources owned here (ActivityMetrics, the scene tree, the live-status pipeline), and nmbrs-tui already depends on nmbrs-runtime so a separate crate would either re-export those types upward or cyclic-depend. The clean split was a fiction; the module organisation gives the same conceptual boundary without the build-graph cost.

Modules

binder

ReadoutBinder — runtime adapter between the static workload binding and the live display surface. See SRD-63 §7.

buf

ReadoutBuf — the surface-supplied output buffer.

builtins

Built-in readout implementations.

color

Colour and style resolution for readout body grammar (SRD-63 §5.2).

context

ReadoutContext — the data facade every readout draws from. See SRD-63 §2.

format

Small presentation helpers shared across readouts.

parse

Body-grammar parser for the workload readouts: block. See SRD-63 §5.1.

readout

The Readout trait + the orthogonal Lod and ContentMode axes the engine renders against.

registry

Static registry of built-in readouts.

snapshot

Snapshot capture for readout renders. See SRD-63 §6.
