- Add CalibrationEntry (heap-allocated array[256], char[] fields to stay within
the 133 MB struct's canonical address limit) plus calibrationMutex_ and
numCalibration_.
- Implement SetCalibrationEntry/ClearCalibration, BroadcastCalibration,
BroadcastConfigAck, HandleSetCalibration, HandleReloadConfig.
- Wire setCalibration and reloadConfig into OnWSCommand dispatch.
- Broadcast calibration to each newly connected client after triggerState.
- Fix JSON round-trip bug: replace JsonGetString/JsonGetBool helpers with a
shared whitespace-tolerant JsonFindValue (tolerates "key" : "value" as
written by HandleSaveSources); add JsonIsFinite (no <cmath>).
- Extend LoadSourcesFile(bool skipActive) to also parse calibration blocks;
SourceIsActive checks live sessions before starting a duplicate.
- Extend HandleSaveSources to persist calibration blocks; emit configSaved ack.
- Reload semantics: calibration replaced wholesale, sources added only.

Parse the optional +Recorder block in Initialise (Enabled/AutoStart/
Directory/MaxFileMB/KeepFiles/StagingMB/FlushIntervalSec/MinDiskFreeMB/
Signals, MB->bytes), apply it to each session before Start (static and
dynamic sources). Drive recorder disk I/O from the push loop via
RecorderFlushTick, and add recStart/recStop/recInfo WS commands plus a
recStatus broadcast/snapshot.

Each session owns a BinaryRecorder. The receive thread configures the
recorder layout at CONFIG time and captures each data packet; the push
thread performs all file I/O via RecorderFlushTick. WS subset overrides
are adopted through an epoch-deferred handoff mirroring the trigger path.
Arm/disarm/flush/info are exposed for StreamHub-level control.

Add a FileWriter-compatible per-source binary recorder: native-type encode
and TypeDescriptor mapping, FileWriter header serialization, subset/quantized/
ACCUMULATE row serialization, and push-thread double-buffer flush with size-cap
rotation, keep-N pruning, fdatasync cadence, disk-free and staging-overflow
guards. Covered by 12 GTests; full suite (83) green.
