Every existing HyperHDR route replaces whatever else is on the LEDs: routes 1/2 hand HyperHDR's own audio effect a device to read, route 3 sends a synthetic spectrum image, and both take over via HyperHDR's priority system. For a setup that already has a real colour source (a screen grabber, a USB capture card) feeding an ambilight-style LED run, none of that is what's wanted -- the colour should stay put and only brightness should react. Read HyperHDR's own source (sources/api/JSONRPC_schema/schema-adjustment.json) rather than guess: "adjustment" is a post-processing command with a scaleOutput parameter (0-2.0) that applies regardless of which priority is currently active. Confirmed the wire format too -- sources/jsonserver/JsonClientConnection.cpp frames it as plain newline-delimited JSON over TCP (default port 19444), nothing like the length-prefixed Flatbuffers protocol the visualiser sink speaks, and with no handshake or registration needed before the first write. sink_hyperhdr_adjust.c sends only that: no image, no priority, so it never competes with an existing grabber. Non-blocking connect with the same poll()+SO_ERROR pattern net/hyperion.c already uses, reconnects every 5s, rate-limited to 20 Hz (a HyperHDR command every audio block would be pointless flooding), and resets scaleOutput to 1.0 on close rather than leaving the LEDs stuck at whatever it last sent. Cross- compiles clean under -Wall -Wextra on the real webOS toolchain. Wired through the same path every other sink follows: registered in sink.c/sink.h, defaults in config.c, fields in frontend/js/app.js (SINK_FIELDS/SINK_HELP), mock.js and ui_smoke.js updated for the new sink card. Bumped to 1.0.3. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
