Components and applications

Displays only validated scalar data received over its private MessageChannel. The host creates an opaque-origin iframe with network access blocked by CSP. Stop removes the frame and releases the channel. No browser permissions, filesystem or parent DOM are exposed.

Replays 10, 20, 30, 20, 10, or a user-selected array of 1–4096 finite numbers. Backpressure pauses production. Source timestamps and session IDs are assigned by the host; no data is uploaded.

process(value, factor) returns value * factor. The module imports nothing and has no memory or start function. Host envelopes preserve units, timestamp, source and session. Non-finite results stop the session.

Reads deviceVersionMajor from the selected WebUSB device object. Does not open interfaces or issue transfers. Generic descriptor compatibility is not proof of product protocol support. Device selection remains explicit; no identifiers enter shared compositions or reports.

Shared Rust Session for native and browser WASM: incremental framing, group admission, BFSP, DTGC, compound, temporal processing, DSC and PNG. Explicit selected image profiles are supported in memory; enhancement0 can run without unused spatial-filter banks. Hosts own USB, storage and display. The browser adapter supports either ABI6 in-memory resources or ABI7 from compatible built-in-profile runtimes. This registry artifact uses ABI6. Maximum256MiB WASM memory. Warmup, explicit state and bounded processing remain required. Reference replays and cross-target numerical differences are measured separately; no clinical or geometric calibration claim.

• frames: out · odb.video.frame/1

Explicit reconstruction-only initialization; binomial FIR, adjustable native display settings, generated grayscale and normalized sector. No external resource files, hardware configuration, USB or network access. Shared Rust processing library for native/WASM. Recording host requires explicit reconstruction purpose. Shared processing sources are pinned by shared-sources.json. No metric calibration or clinical equivalence claim.

• frames: out · odb.video.frame/1

GET-only polling of /status and /image/<session>/<frame> on an explicitly selected loopback bridge. One frame in flight, bounded PNG dimensions and bytes. Known profiles must match. Unidentified recordings are labelled replay and never establish device compatibility. No acquisition, settings, USB transfers or calibrated measurement. Bridge address is runtime-only and excluded from compositions.

• frames: out · odb.video.frame/1

Reads .bin in 64KiB chunks, legacy .odb-capture containers bounded to96MiB, or unbounded-length .odb-stream JSONL with bounded lines. Validates encoding, ordinals and totals. Rejects declared storage losses. Journal/display records never become device commands. File selection is runtime-only, excluded from compositions. The stream provides format candidates, not device identification or acoustic calibration.

• bytes: out · odb.usb.bytes/1

Requires explicit device selection and current phantom setup confirmation. Validates the connected UC5-2S identity, binds the configuration to the current complete PID0, queues IN readers on endpoints6/8/1 and sends the same fixed bootstrap/configuration/Start/Freeze packets as the Rust driver. No retry or further OUT after an uncertain write. WebUSB deadlines close the device; they do not attest acoustic stop. Bounded sessions use duration1–30s and64MiB raw byte limit. An explicit host seconds:null selects continuous reception until Stop/disconnect, with the same bounded IN queues; storage and decoding backpressure belong to the host. No further OUT after an explicit device disconnect. Raw data and configuration remain local.

Receives PNG ArrayBuffers through a private MessagePort. Decodes one frame, draws it on canvas, releases the bitmap, then acknowledges its session and sequence. No network or device access. Shows replay/live provenance, dimensions and uncalibrated status. No distance or diagnostic interpretation.
