…. Principle XIII.

After 3 consecutive TUNE_FAIL_BYPASS results, advance m_currentIndex past
the remaining points on the dying band rather than aborting the whole
sweep. Multi-band runs keep producing useful results when only one band's
antenna is bad (e.g. broken feedline on 80m while 40m/20m/15m are fine).

- Last-band / single-band failure: the skip loop body never executes,
  beginNextPoint() increments past m_points.size() and falls through to
  finishSweep() — matches the prior terminal-abort behaviour for those
  cases (covers the test-plan edge cases).
- First point of a new band fails-bypasses: counter is reset to 0 before
  the recursion, so three fresh fails are required to trigger another
  per-band skip.
- m_skipCount is incremented by (current - skipStart), not (+ 1): the
  triggering point already incremented m_failCount, so only the
  remaining points on the dying band count as skips.
- Audible cue (QApplication::beep) preserved from PR #3050 item #7.
- Message includes the next band name when one exists so the operator
  sees what is about to run.

Principle XIII (The Operator Outranks Every Agent): the operator with
one bad antenna outranks a defensive over-abort — give them the useful
remainder of the sweep rather than the binary "every band aborted"
verdict the previous safety net imposed.

Blast radius: risk_score=0.0504, 5 high-risk affected (top:
RadioModel::transmitModel, RadioModel::isConnected, SliceModel::sliceId).
All five are downstream-transitive callees of onAtuStateChanged whose
behaviour and call sites are unchanged by this patch — the edit
modifies only the consecutive-fail-bypass branch's control flow.

… Principle IV.

Populates rac-canada.json with the license_classes block introduced
in #3050 using Canada's ISED RIC-3 / RBR-4 frequency authorizations:

- B  = Basic              (VHF/UHF only, >= 30 MHz)
- BH = Basic with Honours (all amateur bands)
- A  = Advanced           (all amateur bands)

All HF segments (1.8-29.7 MHz) are annotated "BH,A"; all segments at
50 MHz and above are annotated "B,BH,A"; receive-only beacon markers
keep `license: ""` so they pass through the filter unchanged. The
description is updated to make clear the class overlay is sourced
from ISED (the federal regulator), not from the RAC band-plan
document, which itself does not define class-based sub-segments.

For SSA Sweden, the description is updated to document why no
license_classes block is added: PTSFS 2025:1 treats Swedish amateurs
as a single qualification tier (the older CEPT Class 1 / Class 2
split was retired), so per-segment class filtering would be
misleading. The ATU pre-tune dialog hides the class combobox when no
license_classes block is present (AtuPreTuneDialog::populateLicenseClassRow,
#2649), so this is correct no-op behavior — the description records
the reasoning so a future contributor doesn't retry the addition.

IARU Region 1/2/3 plans are intentionally left unchanged: those
documents are mode-allocation-by-band, not class-allocation, and
operators wanting class filtering should select their national plan
(arrl-us, rac-canada) as the active plan.

Pure data change — no .cpp files modified, no test-target link
surface affected, no codegraph impact analysis applicable (the
dialog code path is data-driven and already in place from #3050).

Principle IV. Region-Aware Data Comes From BandPlanManager: the
class overlay is added to the per-region JSON files that drive
BandPlanManager, keeping the regional-data source authoritative
rather than introducing a parallel class-rules table.

…gionsForBand (#3060). Principle IV.

PR #3050 (closing #2649) added a license-class-aware overload of
BandPlanManager::contiguousRegionsForBand that filters segments by the
operator's class before merging contiguous regions. The filter-BEFORE-merge
ordering is load-bearing: if an allowed segment is adjacent to a disallowed
one, they must NOT merge — otherwise the merged region's center could fall
on a disallowed frequency. The implementation comment calls this out, but
no test pinned the invariant. A future refactor (STL-algorithm
consolidation, parallelisation of the segment loop) could silently
re-introduce the bug.

This commit adds tests/band_plan_license_filter_test.cpp covering the five
scenarios enumerated in the issue:

  1. Empty class → no filter (three-arg with "" == two-arg).
  2. Empty-license segments (BCN markers) always pass.
  3. Class filter drops non-matching segments [E]/[G]/[E,G] under T/G/E.
  4. Adjacent allowed/disallowed segments stay separate (THE invariant).
  5. Trailing-whitespace allowedClass is trimmed; "GE" doesn't match
     "G,E" substring-style; lowercase doesn't match uppercase.

To make scenario 5 pass and to keep the comparison symmetric, the
allowedClass argument is now .trimmed() at the top of the filter — the
segment-side code was already trimmed per element. This is a one-line
forgiveness fix; existing callers that pass already-trimmed strings
(MainWindow::startSwrSweep, AtuPreTuneDialog::populateBands) are
unaffected.

A small public test hook BandPlanManager::setSegmentsForTest is added
so the test can inject synthetic segments without going through resource
loading or AppSettings. Matches the *ForTest naming convention already
used in PerfTelemetry::resetForTest and
AetherAx25LibmodemShim::processRecoveredBitsForTest.

Honors Principle IV (region-aware data comes from BandPlanManager, not
BandDefs.h) by hardening the regression-guard around the manager's
license-class filter — exactly the surface a refactor cleanup pass would
be tempted to consolidate.

Blast radius: risk_score=0.198, 4 high-risk affected (top: MainWindow::MainWindow, MainWindow::buildMenuBar, MainWindow::buildUI). Header change is purely additive (new public inline setSegmentsForTest) — no existing API touched; the high-risk callers don't reference the new symbol and aren't behaviorally affected, only a recompile cascade. The .cpp change adds .trimmed() to one argument — forgiveness-only (strings that previously failed strict comparison may now match); no caller currently passes whitespace.
