José M. Requena Plens Emission and electroacoustics docs: result figures, new plot methods and mirror sync (#363) 1d ago

Adopt ruff 0.16 and modernize the codebase to its default rules (#345) ruff 0.16 broadens the default rule set (pyupgrade, isort, comprehensions and more). Bump the dev pin to ruff>=0.16.0 and apply the resulting fixes across the tree: PEP 585 built-in generic annotations, unquoted annotations under from-future annotations, sorted imports and the assorted small lint fixes. A re-export shim that relied on redundant import aliases now declares __all__ explicitly. The api reference is regenerated for the modernized signatures. No runtime behavior changes; the full test suite passes.

Align the sound power determinations and noise declarations with their standards' clauses (#353) - ISO 3741:2010, 9.1.2/9.1.3: apply the background correction at each microphone position (K1i, Eq. 14), correct the position levels first (Eq. 15) and only then energy-average (Eq. 16). Pre-averaged 1D spectra keep the single-K1 path, documented as an approximation. - ISO 9614-2:1996, 10.6 b: omit the bands failing criteria 1 and/or 2 from the A-weighted total, flag them in the new a_weighting_omitted_bands field and name them in the fiche basis strip (EN/ES); warn when the criteria inputs are absent and the screening cannot run. - ISO 9614-3:2002, C.1.6.2: a band satisfying criterion 5 qualifies as a final result even if FS(2) >= 2. - ISO 3745:2012: bands above 10 kHz no longer abort the determination; only the A-weighted total (outside the ISO 3744 Annex E table) is NaN. - ISO 3744:2010, 8.2.3 / ISO 3746:2010, 8.3.3: K1 = 0 only strictly above the upper criterion; Equation (16) still applies at exactly 15 dB / 10 dB. - ISO 4871:1996, 3.16/6.2: verify dual-number declarations against the sum of the separately rounded declared values (verified_dual), and lay the dual-number fiche out exactly as Annex B.2 (no derived L_WAd row). - Cite clause 8.4 for the apparent directivity indices and note that the 4.3.2 validity limit concerns K2A (per-band check kept, conservative). Hand-derived oracles cover each correction; the ISO 4871 and ISO 9614-2 example fiches, the API reference pages and the llms text are regenerated.
