Kshana run report
Campaign: existing scenario kinds composed into one run, with every number read from a real run of the named kind.
campaign 1ce2687e8ded | L-band jamming from the spectrum, clock holdover and a Galileo-only fallback | chain: 3 phases over 910 s, 0 events, alarm raised on 600 s of the grid | 8 member runs (MODELLED)
Honesty label (result `label`): MODELLED composition of existing scenario kinds. Every number is read from a real run of the named kind; the chaining (additive carry of a channel across a phase boundary, zero-order hold onto the timeline grid, a phase ended at a computed time) is a modelling choice, and each phase carries the label of the kind that produced it.
Capabilities used: 5 VALIDATED, 7 MODELLED, 1 PARTNER (relied on, not provided); see section 5.
Member runs: 8, aggregated in section 3a.
Every field the scenario file sets, flattened to its path. Units come from the result's units block (the field-units schema, docs/field-units-schema.json) where it describes the field, otherwise from the field-name suffix; a unit neither states is shown as not stated.

Each row is a verification-matrix row this run's kinds exercise, with the label and the oracle the matrix gives it (src/verification.rs, docs/VERIFICATION-MATRIX.md). A label grades the capability as the matrix records it; it does not grade this scenario's configuration, and a VALIDATED row does not make the run's inputs measured. A PARTNER row is a discipline the run relies on that Kshana does not provide.
| Capability (matrix requirement) | Label | Used by | Source: oracle | Test evidence |

| RAIM/ARAIM integrity statistical kernel (χ² / non-central χ² / normal laws) The distributional core every protection level rests on: the snapshot fault-detection threshold χ²₁₋ₚfₐ(dof), the missed-detection non-centrality pbias=√λ, and the K_fa/K_md/K_V solution-separation multipliers | VALIDATED exercised | integrity | SciPy 1.17.0 (scipy.stats.chi2/.norm/.ncx2 + optimize.brentq) — independent library (Cephes/Boost), a different algorithm from Kshana's incomplete-gamma series; matched to ≤1e-6 rel. Kernel only. The ARAIM MHSS P_HMI budget *allocation* is no longer without a published numeric oracle — the WG-C ARAIM Technical Subgroup's own worked example now backs the separate 'ARAIM MHSS protection levels against published reference vectors' row, matched at the reference's own TOL_PL = 5e-2 m — so this row's scope is the statistical kernel and that row carries the allocation (see docs/ARAIM_REFERENCE.md) (ExternalDataset) | tests/raim_reference.rs (171 cases: χ² CDF/quantile, normal CDF/quantile, non-central χ² CDF, pbias across the P_fa/P_md/redundancy ranges) |
| GNSS-denied clock holdover Closed-form coast-error growth + holdover-to-threshold; quantum-clock classes | MODELLED exercised | clock | Multi-step clock_state covariance recursion (same-codebase cross-check); the underlying coast-variance & holdover-inversion kernel is externally validated vs scipy (see 'Clock-holdover coast-variance & threshold inversion'). The per-class red-noise-floor holdover figures stay MODELLED (ReferenceImpl) | holdover::tests (vs multi-step Kalman covariance recursion; white-FM exact; round-trip); coast-variance kernel externally validated in tests/gnss_denied_clock_holdover_reference.rs (vs scipy Van-Loan/brentq) |

Labbe, MIT), with F via scipy.linalg.expm and Q via the Van-Loan 1978 block-matrix — an independent reference implementation reproducing kshana's full filter trajectory. Cross-implementation consistency: the clock physics / Allan calibration are not externally validated, so this stays MODELLED (ReferenceImpl) | clock_state::tests (analytic van-Loan Q; NEES; PSD positivity); tests/clock_state_reference.rs (full predict+update trajectory — state x and 3×3 covariance P over 1925 steps / 4 parameter sets vs filterpy 1.4.5; worst |relΔ| 2.8e-14) |

| Reproducibility & software assurance Deterministic, scenario-hashed, SBOM + cross-platform golden gates | MODELLED exercised | every run | SBOM conformance to the official CycloneDX 1.5 JSON Schema (+ valid SPDX identifiers) — an external published standard, zero validation errors over the full dependency graph; the FoM-determinism / byte-reproducibility part remains a pinned self-consistency check, so the row stays MODELLED (ExternalDataset) | tests/golden.rs, tests/determinism.rs, tests/cross_platform_golden.rs; tests/reproducibility_software_assurance_reference.rs (the generated SBOM validates with zero errors against the official CycloneDX 1.5 JSON Schema over the full 66-component shipped graph: default + python + wasm features, dev-dependencies excluded) |

The BOC(1,1) maximum is not at 1.023 MHz: the lobe spans the carrier null to 2.046 MHz and peaks at 0.759 MHz, and the test pins both. The MBOC mix is the ICD definition, checked for unit area and linearity only (ExternalDataset) | spectrum::tests (bpsk_main_lobe_null_to_null_is_two_n_times_1_023_mhz — BPSK(1) 2.046 MHz and BPSK(10) 20.46 MHz located numerically on the closed form; boc11_lobes_are_centred_at_plus_minus_1_023_mhz — carrier null, first null at 2.046 MHz, lobe centre 1.023 MHz, and the exact maximum at 0.7590 MHz against an independent Newton solve of tan y = 2y; ssc_matches_parseval_closed_forms — C/A x C/A 2/(3R_c) = -61.86 dB/Hz, BOC(1,1) x BOC(1,1) 1/(3R_c) = -64.87 dB/Hz, C/A x BOC(1,1) 1/(6R_c) = -67.88 dB/Hz, each within 0.02 dB; q_values_match_kaplan_hegarty — CW at the carrier Q = 1, matched-spectrum noise Q = 1.5, flat null-to-null noise Q = 2.215; mboc_is_a_unit_area_one_eleventh_mix) |
| L-band spectrum waterfall with per-band J/S and effective C/N0 under a scripted jammer timeline The `spectrum` kind: a frequency-by-time grid of the L-band power spectral density (thermal floor k T_sys with T_sys = T_ant + 290 K (F - 1), the signals at their interface-specification minimum received powers, and continuous-wave, narrowband, chirp and matched-noise jammers with on/off times), each cell averaged over its bin and row (chirps exactly over whole and partial sweeps, jammers by duty), per-band effective C/N0 = [1/(C/N0) + sum (J/S) kappa]^-1 per row, J/S per band, in-band J/S, and an SVG waterfall with C/N0 bars. The report carries a cross-check against the `jamming` kind's chain on the same link inputs | MODELLED exercised | spectrum | Reduction to the existing `jamming` kind's anti-jam equation and link budget (the same code, called on the same inputs), and the k T0 F noise-floor closed form. The signal spectra underneath are the validated row above; the jammer powers, timeline and front-end bandwidths are scenario inputs, the spectra are continuous (no spreading-code lines), and no automatic gain control, blanking or antenna pattern acts on the jammer. No measured jammed spectrum is in the repository to check the composite against. The `jamming` kind's representative Q table (broadband 1.0, CW 1.5) differs from the Q this model derives from the spectra (CW at the carrier 1.0, matched 1.5, flat null-to-null 2.2); the report prints both (InternalConsistency) | spectrum::tests (agrees_with_the_jamming_kind_chain — J/S equal to jamming::j_over_s_db and effective C/N0 equal to jamming::effective_cn0_dbhz with Q = 1/(R_c kappa) to 1e-9 dB, and the 32.105 dB anchor of the jamming kind's own test; noise_floor_is_kt0f; chirp_window_splits_whole_and_partial_sweeps; duty_weights_partial_rows; demo_scenario_runs_and_denies_l1_while_l5_survives; defaults_run_with_no_jammer; bad_inputs_are_refused) |

| A chained mission across scenario kinds on one shared timeline The `campaign` kind's phases: each phase runs one or more scenarios of existing kinds through run_toml, reads their outputs into named channels (clock time error and guard, mean effective carrier-to-noise density ratio and tracking floor, vertical protection level and alert limit, position error, satellites tracking, alarm flags) by per-kind presets or explicit result paths, places them at the phase start and holds them onto a common grid, with phase boundaries and events; state is handed on by carry (a channel continues from the previous phase's end value), handoff (a previous phase's number written into the next scenario) and end_at (a phase ends at a time a run computed, such as a spoofing monitor's detection time); a campaign hash and a digest over every member result | MODELLED exercised | campaign | Composition identities against the stand-alone runs of the same kinds: a one-phase campaign reproduces the stand-alone output bit for bit, the carried offset equals the previous run's own last sample, and the phase ended by end_at has exactly the run's detection time as its length.

| Statement | Source |
|---|---|
| MODELLED composition of existing scenario kinds. Every number is read from a real run of the named kind; the chaining (additive carry of a channel across a phase boundary, zero-order hold onto the timeline grid, a phase ended at a computed time) is a modelling choice, and each phase carries the label of the kind that produced it. | result `label` |
| MODELLED: the additive carry and the zero-order hold are modelling choices, and each phase carries the label of the kind that ran it. | kind catalogue (`kshana kinds --json`) |
| MODELLED: the chaining is a modelling choice (additive carry, zero-order hold), and each phase is as good as the kind that ran it. E1 recovering under the CW tone rests on the spectrum kind's continuous-spectrum treatment (a CW tone on the MBOC carrier null couples nothing); a real tone would couple through the code's spectral lines. | scenario file comment, lines 30 to 33 |
