Finding 1: revert the comma/quote strip added in 3cb998c from
normaliseCal() in calibration.js. The strip broke byte-identical parity
with Go CalConfig.Normalise and C++ StreamHub::SetCalibrationEntry, both
of which only trim whitespace and cap at 16 UTF-8 bytes. Delete the
companion test that asserted the now-removed behaviour (suite returns to
18 tests).
Finding 2: fix the actual CSV-safety problem at the point of use in
exportAllCSV() in app.js. Header cells (time column and signal columns)
are now RFC 4180-quoted: wrapped in double quotes with any embedded
double quote doubled. This safely handles units or signal names that
contain commas or quotes without touching normaliseCal.
Finding 3: update two stale comments in app.js that called the trigger
threshold or rawFromNorm result 'raw' — Task 9 moved trig.threshold into
calibrated units throughout, so the comments now say 'calibrated'.

refreshVScaleMenu() was unconditionally removing the cal-invalid class
from all three calibration inputs, which silently cleared the red-border
error indicator on a field the user was editing whenever a hub
calibration broadcast arrived. Apply the same focused-element guard
already used for .value writes so a rejected value's error styling
persists until the user corrects it.

Adds the Cal row (Scale / Offset / Unit / Reset) to #vscale-menu, its
CSS, and the refreshVScaleMenu() / commitCal() logic that wires it to
calTable and the hub via setCalibrationWS.

TextEncoder always emits well-formed UTF-8, so truncation can strand at
most a lead byte plus three continuations — one repair pass covers it.
The C++ hub needs a loop because its input is raw bytes off the wire.
Also drops a dead variable from the byte-boundary test.

normaliseCal was using String.length/.slice() (UTF-16 code units), so
multi-byte characters like °, Ω, µ could slip through oversized. Now uses
TextEncoder to slice at 16 bytes, then repairs any incomplete trailing
UTF-8 sequence by walking back over continuation bytes to find the lead
byte and dropping the incomplete rune — exactly mirroring Go's
utf8.DecodeLastRuneInString loop and the C++ walk-back in
StreamHub::SetCalibrationEntry. Adds 4 new test cases covering the
non-ASCII/boundary scenarios, and corrects the canonical test command in
the task-6 report to 'cd Client/udpstreamer && node --test'.

Implements Calib JS module (calibration.js) with affine transform primitives,
CalTable, and normaliseCal matching Go CalConfig.Normalise semantics; 14 node
--test cases all pass. Loads before app.js in index.html.
