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.

- 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'.

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.

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
field, add buildCalibrationMsg and buildConfigAckMsg builders, send calibration
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).

Design for a per-signal affine calibration (scale/offset/unit) applied
client-side and stored server-side alongside the source list, so signals in
raw units can be read in engineering units and the setup survives a reload.

Task 7 added --skip-coverage/--skip-stress/--skip-datasources/
--skip-recorder/--skip-debug/--skip-tcplogger but the AGENTS.md table row
was never updated to mention them; it also still listed a --stress flag
that has never existed. Sync with the script's actual --help output.

The final whole-branch review found runDebugScript only checked
mc.IsConnected() after sending FORCE/TRACE/BREAK/UNFORCE -- a liveness
check that would PASS even if DebugService silently no-op'd every command
(e.g. a signal-name/wire-format bug), undercutting the design's stated
rationale for this scenario ("catching wire-format/serialization bugs the
in-process suite cannot"). This mirrors the tautology already fixed for
the tcplogger scenario in an earlier task, but had not been applied here.
Added waitForAck(), which polls the sink's recorded "text_line" events for
DebugServiceBase::HandleCommand's real "OK <TOKEN> <count>\n" reply and
requires count > 0 -- HandleCommand prints this for every one of
FORCE/UNFORCE/TRACE/BREAK regardless of enable/disable direction, and
count is always "number of signals actually matched", so count==0 means
the signal path was never resolved. Verified with a real negative control
(temporarily pointing all commands at a nonexistent signal name): the
scenario now correctly FAILs, then reverted and reconfirmed PASS against
the real signal.

The final whole-branch review (post Task 10) found two real cross-task
integration bugs:
- run_e2e.sh's coverage-instrumented scenario re-run only rebound OUT_DIR
in its subshell, not WORK. proc_perf.py/plots.py write perf_*.json and
wave_*.png into WORK, so every --cpp-coverage run (the default) silently
clobbered the primary pass's perf/waveform data with the instrumented
re-run's numbers before report_build.py read them -- defeating the
"uncontaminated performance metrics" goal of the coverage-double-run
design. Fixed by rebinding WORK the same way OUT_DIR already was.
- report_build.py's build_e2e() iterated all results["scenarios"] with no
kind filter, so the direct/recorder/debug/tcplogger scenarios (already
covered by their own dedicated report sections since Task 8) also leaked
into the chain-only Scenarios/Performance sections and headline e2e
pass/fail count as degenerate rows. Fixed by filtering to kind=="chain".
Verified end-to-end with a full ./run_e2e.sh run: coverage pass now writes
to /tmp/chain_e2e/coverage_pass/ (confirmed via log), and report_data.json's
e2e section now reports 51 (chain-only) scenarios instead of all 56.

The post-coverage restore step ran `make clean` (which also wipes
Test/GTest, Test/Integration and Test/Components/*) but only rebuilt
`core apps`, leaving MainGTest.ex/IntegrationTests.ex deleted after
every --cpp-coverage run instead of restored to their plain (non-gcov)
form.

README.md and Docs/StreamHub-Developer.md still pointed at the deleted
run_e2e_test.sh / Test/E2E/streamhub Go client after their removal in the
previous commit; repoint at Test/E2E/suite/run_e2e.sh.
Extends report_build.py with build_by_kind() (per-scenario-kind pass/fail
rollup) and a ported build_stress()/stress_headline()/stress_plots() (scaling
curves per stress axis), wires both into the headline KPIs, regression
tracking, and report_data.json. E2E_Report.typ renders the four new
per-kind tables plus a Stress Tests section (per-axis case tables + scaling
plots, gracefully degrading to placeholders when a kind/stress data is
absent). run_e2e.sh now passes --stress-results so the report actually
receives real stress data instead of silently omitting it.

Adds a trimmed debug_e2e.cfg (DebugService on 8080/8081, TcpLogger on
9090) and two new scenarios (s55_debug_force_trace_break, kind=debug;
s56_tcplogger_delivery, kind=tcplogger) reusing it, with matching
run_e2e.sh scenario-list/dispatch wiring and debugclient build steps.
Also fixes a real bug found while wiring s56: debugclient's tcplogger
check was tautological (it matched MarteController's own local
"CMD"-level echo of the outgoing command, which contains the same text
as the triggered event, instead of a line actually delivered over the
real TCPLogger TCP socket) and its trigger command (an invalid FORCE)
never reaches DebugServiceBase's REPORT_ERROR at all. Switched the
trigger to a MSG-to-missing-destination command (which does call
REPORT_ERROR) and the match to require the real log text
("not found in ORD"), recorded only after a connect-settle baseline —
verified with a positive run (real Warning-level TCPLogger line
received) and a negative control (LogPort=0 disables TcpLogger and the
scenario correctly FAILs).

Standalone headless client that drives a running MARTeApp.ex's
DebugService (TCP 8080 commands, UDP 8081 trace) and TCPLogger (TCP
9090) via marte2debugger/controller's NewHeadlessMarteController, for
the upcoming Test/E2E/suite "debug"/"tcplogger" scenario kinds. Scripts
FORCE/TRACE/BREAK for -mode debug, and triggers+waits for a TCPLogger
log event for -mode tcplogger; reports PASS/FAIL as
result_<scenario>.json/status_<scenario>.txt in -out.
Client/debugger was entirely package main, which Go forbids importing from
another module ("is a program, not an importable package") -- discovered
while wiring the new debugclient E2E tool against NewHeadlessMarteController.
Move martecontrol.go and its test into a new marte2debugger/controller
subpackage (package controller) and update Client/debugger/main.go to call
controller.NewMarteController/controller.DangerousCommandsEnabled. No
behavioral change to the browser-facing server.
Add a sink func(v any) field so MarteController's event stream can be
routed somewhere other than the browser WebSocket hub. NewMarteController
now sets sink to broadcast through the hub as before; a new
NewHeadlessMarteController(sink) constructor builds an instance with
hub == nil for the upcoming debugclient E2E tool. Direct m.hub.* calls
(SetSourceState/UpdateConfigForSource/PushDataForSource) are now guarded
with nil checks so a headless controller doesn't panic.
Extends the scenario-list builder and main loop to actually execute
s52_direct_unicast/s53_direct_multicast (self-contained single-MARTeApp
FileReader->UDPStreamer->UDPStreamerClient->FileWriter round trip) and
s54_recorder (StreamHub BinaryRecorder round trip, ported from
run_recorder_e2e.sh) alongside the existing chain scenarios, and tags
each results.json record with its scenario kind.
