    Document payment-frequency parameters in cross-currency helpers
    
    Add \param documentation for the cross-currency basis-swap rate helpers
    describing the index-tenor default and the quote-to-base fallback, and
    rename the quoteCcyPaymentFrequency constructor parameter to
    quoteCurrencyPaymentFrequency to match the sibling baseCurrencyIndex and
    quoteCurrencyIndex parameters.  Add a test pinning the quote-to-base
    fallback behavior.

    Treat NoFrequency as unset in cross-currency basis swap helpers
    
    A NoFrequency passed to the payment-frequency parameters now normalizes
    to nullopt, preserving the pre-optional behavior (derive the schedule
    from the index tenor) instead of building a zero-length Period(NoFrequency)
    schedule, which Schedule silently maps to the Zero date-generation rule.

    Use ext::optional<Frequency> for payment frequency in cross-currency helpers
    
    Standardizes the cross-currency basis swap rate helpers on the
    ext::optional<Frequency> pattern (with ext::nullopt default) that
    other rate helpers in the codebase use, instead of the NoFrequency
    sentinel value. Covers both paymentFrequency and quoteCcyPaymentFrequency
    to keep the file internally consistent.

    Update HullWhite r0 when termstructure relinks (#2592)

commit b604cd28347d706c01beac2dce81996baaa6c752
Author: metsw24-max <metsw24@gmail.com>
Date:   Fri, 22 May 2026 15:24:03 +0530

    Fix out-of-bounds write in FastFourierTransform ctor for order=0
    
    The constructor allocated cs_ and sn_ with size 'order' and then
    unconditionally wrote to cs_[order-1] and sn_[order-1]. When 'order'
    is 0 (e.g. when callers chain FastFourierTransform::min_order(1),
    which returns 0), both vectors are empty and the indexing wraps to
    size_t(-1), producing an out-of-bounds write that segfaults under
    debug-iterator-checked standard libraries.
    
    A transform of size 1 == 1<<0 reduces to a copy and needs no twiddle
    factors, so skip the setup when order is 0. The transform loop body
    'for (s = 1; s <= order; ++s)' already handles the order==0 case
    correctly.

    Fix trinomial tree excessive branching with gated dx floor
    
    Closes #364.
    
    When a TimeGrid contains mandatory time points separated by very
    short intervals (e.g. millisecond gaps inside an annual schedule),
    the trinomial tree's per-step dx = v*sqrt(3) shrinks to a tiny
    value at the short step.  Because subsequent steps still need to
    cover the full state range, the integer-rounded `temp` index for
    each parent node lands far from j=0, causing the j-range to
    explode (Mandal observed several hundred nodes on a 50-step
    grid).
    
    Apply a Clewlow-Strickland (1998) global dx floor based on the
    largest natural dx in the grid, but only on grid steps that are
    at least two orders of magnitude shorter than dtMax
    (kFloorThreshold = 0.01).  This preserves classical
    per-step dx = v*sqrt(3) on uniform and typical non-uniform grids
    (weekend rolls, 1-day mismatches) while bounding node count on
    the pathological small-mandatory-gap case.
    
    Probability formulas (dual branch on dxIsFloored):
    
      Unfloored regime (dxIsFloored == false): keep upstream's
      classical Hull-White / Clewlow form character-identical:
    
          e3 = e*sqrt(3)
          p1 = (1 + e^2/v^2 - e3/v) / 6
          p2 = (2 - e^2/v^2) / 3
          p3 = (1 + e^2/v^2 + e3/v) / 6
    
      This is the hot path covering every current cached-value
      pricing test (bermudanswaption.cpp testCachedG2Values,
      callablebonds.cpp), so cached values are bit-for-bit identical
      to upstream master by code structure -- not by IEEE-754
      coincidence as in the prior single-formula approach.
    
      Floored regime (dxIsFloored == true): use the general dx-based
      moment-matching form, which redistributes mass toward the
      middle node when dx is floored:
    
          p1 = (v^2 + e^2 - e*dx) / (2*dx^2)
          p2 = 1 - (v^2 + e^2) / dx^2
          p3 = (v^2 + e^2 + e*dx) / (2*dx^2)
    
      These reduce to (1/6, 2/3, 1/6) when dx = v*sqrt(3).
      Non-negativity requires v^2 >= |e|*(dx - |e|), which always
      holds in the unfloored regime with naturally-rounded temp;
      in the floored regime when v << v_max the weights can go
      slightly negative.  Documented in code as the accepted cost
      of the pathology fix; first two moments are matched exactly,
      so signed weights remain arithmetically consistent for linear
      payoff propagation.  Hull-White-style alternative branching
      does not solve this regime (it solves the orthogonal
      boundary-drift problem).
    
    Branch flag semantics:
    
      dxIsFloored = (dxNext > dxNatural), defined post-computation,
      tracks whether the floor was *effective* at this step rather
      than whether the gate fired.  For Hull-White with constant
      sigma the two definitions agree, but for time-dependent
      diffusions a short step can have its natural dx already exceed
      dxFloor -- the gate fires but dx is unchanged, and we should
      use the classical formulas plus the safety assertion.
    
    Floor diagnostics:
    - Floor activation threshold lifted to a file-scope constexpr
      kFloorThreshold inside namespace QuantLib for clarity.
    - Defensive QL_ENSURE on probability non-negativity in the
      unfloored regime, gated on !dxIsFloored && !tempBumped.  The
      tempBumped flag tracks the isPositive while-loop that bumps
      `temp` upward to keep the underlying positive (CIR family);
      in that bumped state |e| can exceed dx/2 and probabilities
      can legitimately go negative, exactly as upstream allowed
      before this change.  The guard still protects the most common
      path (no floor, no bump) against future drift.
    - dxFloor is computed via direct iteration over actual step
      variances (dxFloor = sqrt(3 * max_i variance(t_i, 0, dt(i)))),
      keeping the integration strictly within the declared grid
      horizon by construction.  For Hull-White with constant sigma
      this is identical to a dtMax-windowed form, so cached test
      values are unchanged; for time-dependent diffusions it avoids
      floating-point fragility from any `terminal - t_i` subtraction
      and yields a slightly tighter bound.
    - The preflight pass that derives dtMax and dxFloor also caches
      per-step variances into std::vector<Real>; the main loop reads
      v2 from the cache rather than re-invoking process->variance().
      Halves the variance() call count, measurable for processes
      with non-trivial variance evaluation cost.
    
    Test coverage (test-suite/trinomialtree.cpp):
    - testSmallMandatoryGapDoesNotExplode exercises the small-
      mandatory-gap pathology (1ms gap inside an annual grid) and
      asserts bounded node count via the derived 2*nSteps+1 bound.
    - testFloorThresholdBoundary probes immediately on either side
      of kFloorThreshold (gapRatio = 0.0099 floored, 0.0101
      unfloored).  The probe scans the constructed TimeGrid for the
      minimum-dt step (rather than hard-coding an index that depends
      on TimeGrid's prepend-t=0 behaviour) and reports both
      tree.dx(shortIdx+1) and the natural reference computed in the
      same operation order as production (sqrt(v2)*sqrt(3.0), not
      sqrt(3.0*v2)) so BOOST_CHECK_EQUAL is bit-stable across
      compilers.  The below-side asserts shortStepDx >
      shortStepNaturalDx (floor positively active); the above-side
      asserts strict equality (floor positively inactive).  This
      catches drift of kFloorThreshold in either direction -- a
      one-sided check would only detect upward drift.
    
    A pricing-level regression test for the floored regime
    (Bermudan swaption / callable bond on a small-mandatory-gap
    grid) is deliberately deferred: it would require modifying the
    engine's internal TimeGrid construction to inject a mandatory
    time outside any exercise date, which is outside the scope of
    this trinomial-tree fix.  The unfloored hot path covering every
    current cached-value pricing test is bit-for-bit identical to
    upstream by construction; the floored regime's negative-
    probability invariants are covered by static analysis in code
    comments and the existing trinomial-tree unit tests.
    
    1293/1293 tests pass.

    Make term-structure handle a trailing default arg in G2 processes
    
    Moves the Handle<YieldTermStructure> parameter introduced in a6d68458c
    to the end of the G2Process and G2ForwardProcess constructor signatures
    and defaults it to an empty handle, so existing code using the original
    G2Process(a, sigma, b, eta, rho) / G2ForwardProcess(a, sigma, b, eta, rho)
    calls keeps compiling. Test-suite call sites updated to match.
    
    No behavioural change: an empty handle still means "no curve", which the
    existing implementation already handles in drift, expectation,
    initialValues, and phi.

    fuzz: add additional harnesses to be consumed by OSS-Fuzz
    
    Adds additional fuzzingh harnesses that will be run on OSS-Fuzz. The
    main goal is to increase code coverage, for which a recent code coverage
    report is available at
    https://storage.googleapis.com/oss-fuzz-coverage/quantlib/reports/20260504/linux/report.html
    
    The recent added harnesses has shown an increase, although there is
    still much room to go:
    https://introspector.oss-fuzz.com/project-profile?project=quantlib
    
    The harnesses added here roughly doubles the coverage on a short local
    run.

    Shift G2Process state so PathGenerator paths are curve-consistent (#1904)
    
    Following review on PR #2555, the simulated state of G2Process and
    G2ForwardProcess is now (x + phi(t), y) instead of the raw zero-mean
    OU pair, so that state[0] + state[1] = r(t) directly. This mirrors
    HullWhiteProcess and means a MultiPathGenerator built on G2Process
    produces short-rate paths whose expectation matches the initial curve.
    
    Concretely:
    - drift gains a*phi(t) + phi'(t) on the first component
    - expectation gains phi(t0+dt) - phi(t0)*exp(-a*dt) on the first component
    - initialValues returns (phi(0), 0); x0() returns phi(0)
    - shortRate(t, z1, z2) now returns z1 + z2
    
    diffusion, stdDeviation, and covariance are unchanged because the
    shift is deterministic. phi(t) is unchanged and still exposes the
    curve-implied offset. Empty-handle behaviour reduces to the old
    zero-mean OU pair.
    
    Tests in test-suite/g2process.cpp updated to reflect the new
    semantics, and a new MultiPathGenerator test verifies the empirical
    mean of state[0] + state[1] matches phi(t).

    Improve `CompoundingOvernightIndexedCouponPricer::compute` calculation
    
    - Fix valueDate schedule generation when accrualStartDate falls on a fixing holiday (possible for SOFR swaps as they have different calendars for fixings and schedule generation).
    - interestDates are no longer adjusted for lookback when applyObservationShift is enabled (we can use valueDates in this case). This is needed to determine how far through rate calculation period we are for the purposes of accruals.
    - fix lockout date handling, so that lockouts only apply at the end of the period.
    - expose exCouponDate on OvernightIndexedCoupon.

    Add term structure, phi, and shortRate to G2 processes
    
    Extends G2Process and G2ForwardProcess with a yield term structure
    handle, deterministic drift phi(t), and a shortRate(t, x, y) helper
    so the processes can be used for short-rate simulation consistent
    with an initial curve. Also adds a corresponding g2process test.

    Avoid repeated calls to Interpolation::update()
    
    Add a flag (defaulting to true) for whether to run update when the
    interpolation is constructed. This matches the current behavior of most
    interpolations. Pass update=false when we don't need this, because we
    will call update later. In particular, do this in composite
    interpolations (log and mixed) and bootstrappers where we currently call
    update multiple times unnecessarily (usually all but the last call are
    before the data for the interpolation is set).
    
    Note that:
    1. Interpolations that do not support the new update argument are called
       without it.
    2. Interpolations are assumed to call update during construction when
       not passed update=false. This is true for most current interpolations
       except XABR. Since XABR is not used in interpolated curves, this is
       out of scope for this PR.
    3. Interpolation2D implementations used a different convention and never
       called update in constructors, so they are also out of scope for the
       change.
    4. GlobalBootstrap currently has an issue where for rates-based traits
       it calls methods that use interpolation (zeroRate and forwardRate)
       without updating it first. This will be addressed in a separate PR.
    
    Fixes #2447
