Adds TimeBase.h/cpp with ClockOffset (latched wall-clock offset with
one-sided recalibration on positive drift only, so early-arriving packets
do not wobble the trace) and HrtRateFit (sliding-window OLS that recovers
an unknown hrt tick rate from receive timestamps). Also adds
TimeSignalScale() which maps UDPS type codes to seconds-per-count.
9 new tests, all 28 pass.

Gap 1: closeLeaf was only tested closing the first sibling; added test
closing the second sibling to cover the else branch of parent->a.get()==leaf.
The test verifies the correct sibling survives with its signal intact.
Gap 2: closeLeaf was only tested at depth 1 (root's direct children);
added test with depth-2 leaf (in right subtree) to exercise findParent's
recursive search in both subtrees. Tests that the correct leaf is promoted
and remaining signals are preserved.

The ramp data in EmitsPointsInTimeOrder never produced a bucket whose maximum
preceded its minimum, so an implementation ordering the emitted pair by value
instead of by time would have passed. Replaced with an explicit two-bucket case
whose second bucket reverses the order.
file(COPY) is a hard configure error on a missing source, so a checkout without
the sibling StreamHub resources failed to configure despite the ASCII-icon
fallback the block above had just selected.
Plan amended to match on both points.

Each of these would have surfaced as a compile/link failure or a reviewer
rejection mid-execution, when the implementer holding the task has no view of
the neighbouring task that contradicts it.

A bench scope that attaches straight to one UDPStreamer through the
standalone C client, so it can be dropped on a machine with no StreamHub,
no Go and no browser. Records the decisions that are easy to get wrong:
the time-base rules must follow UDPSourceSession rather than the C
library's arrival-time estimate, decimation must be min/max rather than
LTTB so glitches survive, and the ring must be sized past the trigger
window by an explicit harvest margin.

Consuming a UDPStreamer feed so far meant either linking MARTe2 (UDPSClient)
or writing Go (Common/Client/go/udpsprotocol). Common/Client/c fills the gap
for plain C/C++ integrators: two files depending on nothing but libc and BSD
sockets, covering the whole receive path — CONNECT, fragment reassembly,
CONFIG/DATA decoding with dequantisation, keepalives and silence-triggered
reconnect. No threads are spawned; udps_client_poll() does all the work and
runs every callback, so it drops into an existing event loop unsynchronised.
Verified against run_udp_producer.sh at 1 Msps: unicast (120 MiB, no loss) and
multicast with 12-fragment cycles (116k datagrams, no loss).

UDPSClient::ConnectMulticast was calling the single-arg BasicUDPSocket::Join,
which forwards NULL as the local interface and lets the kernel bind to
INADDR_ANY. On a multi-homed host (or when the server sends on loopback via
Interface = "127.0.0.1") the client joins the wrong interface and silently
receives nothing.
Fix: read the optional Interface key inside the useMulticast block in
UDPSClient::Initialise; in ConnectMulticast call the two-arg
Join(group, interface) when Interface is set, and fall back to the one-arg
call otherwise to preserve the existing INADDR_ANY behaviour for configs that
omit it.
Forward the new optional Interface key through UDPStreamerClient (read from
DataSource config, written into the UDPSClient ConfigurationDatabase only
when non-empty). Extend the "Joined multicast group" log to report the
interface name or "default".
Regression test TestExecute_MulticastReceivesDataOnInterface: mock TCP
control listener + multicast UDP DATA socket with IP_MULTICAST_IF set to
127.0.0.1, verifying a uint32 value of 424242 reaches DataSource signal
memory. Confirmed FAILED without the Join fix and PASSED with it.
Suite: 133/133 (was 132/132 before this commit).

UDPSServer parses Interface with inet_addr() to set IP_MULTICAST_IF, so
a name like "eth0" yields INADDR_NONE and Initialise fails. Every
example in UDPStreamer.md used "eth0", so anyone following the docs hit
that failure; the .cfg files in Test/ already used a dotted-quad.
Replace the examples with 192.168.1.10, state the dotted-quad
requirement in the parameter table and the Multicast section, and note
that receivers must join on the matching interface or they silently
receive nothing.

Commit 3e0a481 made Interface mandatory for multicast in both
UDPStreamer::Initialise and UDPSServer::Initialise and updated
Docs/UDPStreamer.md, but left the GTest configs untouched. All four
multicast tests have failed since.
Add Interface to the five multicast configs. The field is parsed with
inet_addr(), so it takes a dotted-quad, not an interface name; 127.0.0.1
keeps the tests self-contained and off the LAN.
TestInitialise_MulticastMode_InvalidDataPort was passing for the wrong
reason: UDPStreamer.cpp rejected it on the missing Interface before the
DataPort == Port check could run. It now proves what its name claims.
TestExecute_MulticastConnectDataDisconnect additionally needed the
two-argument Join(): the single-argument form passes INADDR_ANY, so the
reader joined the default-route interface while the server sent on
loopback via IP_MULTICAST_IF, and the DATA datagram never arrived.
GTest: 132/132 (was 128/132), multicast subset stable over 3 runs.

Per-signal data calibration (value = raw * scale + offset) with an optional
unit override, plus sources+calibration persistence in a single config file,
implemented identically in the Go hub and the C++ StreamHub.
- calibration.js: fix baseSignalName('[0]') parity with Go/C++ (>= 0 not > 0)
- calibration.test.js: add assertions for '[0]' edge case in two existing tests
- app.js: remove stale typeof guard around refreshVScaleMenu (always defined)
- app.js: call refreshTrigThresholdField on trig-signal change (both assignment sites)
- index.html: drop maxlength='16' on unit input; normaliseCal is the sole enforcer
- configcheck/main.go: delete dead nextOneOf function (no callers)
- hub_calibration_test.go: delete orphaned waitBroadcast comment (function never existed)
- calibration.go: correct arrayIndexSuffix comment to document known Go/C++ difference
- Docs/StreamHub-API.md: add calibration entry count and unit byte limits to §5 table
- spec: fix configReloaded missing path field, '16 chars'→'16 UTF-8 bytes', StreamString→char[], chain scenario→configcheck program, four→five new frames

Finding 1 (HandleReloadConfig data loss): move ClearCalibration inside
LoadSourcesFile so the table is wiped only after a successful fread.
Adds a clearCalibration bool parameter (default false); the reload path
passes true, the startup path passes false.
Finding 2 (JSON injection via unit/source/signal): add JsonEscape()
static helper (escapes \", \\, \n \r \t, and \u00XX for other control
chars). Applied at all three emission sites: BroadcastCalibration,
HandleSaveSources, and BroadcastSources (label). Teach JsonGetString to
unescape the same set on read, so values round-trip correctly.
Finding 3 (%.17g verbosity): add ShortFloat() static helper that tries
%.15g then %.16g then %.17g, stopping at the first precision whose
strtod() output compares equal to the original. Applied at both float
emission sites. 0.1 now prints as "0.1", not "0.10000000000000001".
Minor: fix two inaccurate comments in StreamHub.h — the CalibrationEntry
rationale (not a 133 MB / address-limit issue; the real reason is no
per-entry heap churn, STL-free, trivially copyable) and "chars" to "bytes"
for the unit cap.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Finding 1 (Critical): replace "16 chars" with "16 UTF-8 bytes" in the
setCalibration unit field description (StreamHub-API.md) and the Cal·Unit
toolbar row (WebUI.md); note that multi-byte characters consume more than
one byte and that truncation never splits a character.
- Finding 2 (Important): correct the claim that a sources broadcast after
reloadConfig is conditional on new sources being added — that is true only
of the Go hub. The C++ hub calls BroadcastSources() unconditionally on
success. Both the reloadConfig command description and the configReloaded
event description in StreamHub-API.md are updated; the Reload bullet in
WebUI.md is updated with a brief note. Clients must tolerate an unsolicited
sources frame after any reload.
- Finding 3 (Minor): the configSaved failure example used "no SourcesFile
configured", which matches neither hub. Corrected to the C++ form
"no sources file configured" and added a note that the exact error text
is not part of the protocol contract (Go uses "no sources-file configured").
Source evidence: calibration.go (maxUnitLen, len(), rune-repair loop),
StreamHub.cpp (kMaxUnitLen, byte strncpy, HandleReloadConfig unconditional
BroadcastSources, HandleSaveSources error string).

Update Docs/StreamHub-API.md (new setCalibration/reloadConfig commands,
calibration/configSaved/configReloaded events, §4 config file format),
ARCHITECTURE.md §6 (updated command/event tables and Config File Format
subsection), Docs/WebUI.md (Cal row in V-Scale Toolbar, Sources & Config
sidebar section). Also corrects the spec's Validation sentence to match
the shipped cal-invalid border behaviour instead of silent field revert.

Renames the "Add Source" section to "Sources & Config" and replaces the
fire-and-forget "Save list" button with Save and Reload, plus a one-line
status area that renders the hub's configSaved/configReloaded ack.
onConfigAck replaces the no-op stub Task 7 left behind. It branches on the
frame type because configSaved carries a path and configReloaded does not,
and surfaces the hub's error text on failure rather than failing silently.
The status is kept outside the DOM because buildSidebar() recreates this
section on every sources broadcast.

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.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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'.

Fix round 1 review findings:
1. Frame-matching strategy: add protocolFrameTypes set; next() now fails immediately
on an out-of-order protocol frame instead of silently discarding it. Ambient
frames (data, stats, triggerState, monotonicState) are logged and skipped.
nextSkipping() accepts explicitly-listed protocol frames that legitimately differ
in order across hubs (connect-time "sources" before "calibration" in C++).
2. BroadcastSources documented exception: the extra "sources" frame C++ emits after
reload is accepted and logged as [KNOWN DIFFERENCE] with full rationale; the
report recommendation to remove it has been retracted (it is required for correct
client-side source-list updates after reload-with-new-sources).
3. Sort-order constraint exercised: three calibration entries submitted in
reverse-sort order (src2/Beta, src1/Zeta, src1/Alpha); each broadcast and the
saved config file are asserted to be sorted by source then signal.

The single-pass repair left invalid bytes when the candidate lead byte
had class 0 (illegal 0xF8-0xFF bytes, or a bare continuation byte
reached after the 3-byte backward-scan cap). Convert to a loop with a
`cut` flag mirroring Go's loop: each iteration either makes no cut
(exits) or strictly reduces ulen by >= 1 byte (terminates in <= 16
iterations). Also treat expected==0 as a cut target, matching Go's
behaviour of stripping any byte that decodes as an invalid one-byte
sequence.

The previous walk-back in SetCalibrationEntry was unconditional, corrupting
short valid units ending in multi-byte characters (e.g. Omega, mu, degree).
Also failed to drop an orphaned lead byte left after stripping continuation
bytes. Restructured to use a 256-byte staging buffer so truncation can be
detected, then repair runs only in the truncation branch. Algorithm now
matches Go CalConfig.Normalise() exactly: scan back over continuation bytes
(up to 3), find the lead byte, derive expected sequence length, cut if
incomplete. Covers all cases: orphaned continuation, orphaned lead, cut on
lead byte.

Finding 1: Add TrimInPlace helper; apply trim→strip-[i]→empty-check order
in SetCalibrationEntry (matching Go Normalise()), so whitespace-padded
source/signal from WS clients normalise identically to config-file loads.
Finding 2: Trim unit before truncating to kMaxUnitLen, then walk back
continuation bytes (0x80-0xBF) to avoid leaving a partial UTF-8 rune,
matching Go's utf8.DecodeLastRuneInString loop.
Finding 3: BroadcastCalibration and HandleSaveSources now emit entries
sorted by source then signal (insertion sort over an index array, no STL),
producing byte-identical calibration frames and config files to the Go hub.

- 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.

Wire five new WebSocket frames into hub.go: setCalibration (client→hub),
calibration (hub→client broadcast), reloadConfig (client→hub), configSaved and
configReloaded (hub→client acks with ok/path/error). Extend hubCmd with cal

on client connect, and run Save/Reload on separate goroutines to avoid blocking
the Run() select loop.

Finding 1: strip trailing [digits] array-element suffix from Signal so one
calibration entry covers an entire array signal, matching the C++ strchr
truncation and the JS equivalent.
Finding 2: after the 16-byte Unit truncation, drop any trailing partial UTF-8
rune so json.Marshal never emits replacement characters; keeps byte limit in
sync with C++ strncpy(u, unit, kMaxUnitLen).
