Results read their regime from the values they hold, and refuse the numbers of another regime - #953
Conversation
…umbers of another regime A result no longer stores a regime or a classification beside the values it was read from. Thirteen result classes that kept the answer their function reached by comparing values they hold with a constant or a printed threshold now read it as a read-only property, and the numbers a regime selects are held to it when the result is built, so a result built by hand or rewritten with dataclasses.replace can no longer carry one regime beside the values of another. A value exactly on a boundary falls where the source puts it; the IEC 60534-8-4 cavitation threshold, which the standard does not settle one way, is read as turbulent and recorded as an errata entry. The functions take the same arguments and return the same numbers.

📝 WalkthroughWalkthroughThe change makes several result classifications read-only properties derived from retained inputs. It adds construction-time checks for dependent values, updates result constructors and calculation functions, and revises API, upgrade, changelog, and errata documentation. It also adds tests for the derived properties and validation rules. ChangesDerived building results

Numerical conformance1893/1893 checks pass across 111 domains and 523 standards (227 normative designations, 125 further published sources). Used in the tables below is how much of that clause's published tolerance the deviation consumes: 100 % sits exactly on the limit, 5 % uses a twentieth of the allowance, and a dash means the clause states no two-sided tolerance for the quantity, so there is no budget to spend. It is reported and never used to decide a verdict, which is settled at full precision before any rounding. Nothing moved: same 1893 checks, same verdicts, same numbers. Closest to their published limit (top 5) The rows with the least room left, so the ones a change is most likely to push over.

Update the "See also" errata count to match the new count of seven.
Line 329 now says "the seven defects that annex and its clauses carry". Line 311 still says "the six entries this page rests on". The new Equations (19a)/(19b) entry belongs to this page. The two counts on the same page now disagree. The generated site/public/llms/llms-devices-noise-control-valves.txt copies the stale "six" at Line 761. The site edition of this guide probably has the same sentence. Fix the sentence in this file, in the site edition and in its Spanish twin, then regenerate the llms file.

A result no longer stores a regime or a classification beside the values it was read from. Thirteen result classes used to keep the answer their function reached by comparing values they hold, or could hold, with a constant or a printed threshold: whether the tapping machine's hammer is over-critical (Hopkins Eq. 3.95), whether an IEC 60534-8-4 valve is turbulent or cavitating, which of the five IEC 60534-8-3 regimes a gas valve is in, whether terrain screens a rotorcraft path (NORAH2 guidance Appendix D), which ISO 8253-1 reversals are peaks and which ones 6.3.5 a) keeps, which IEC 61094-2 Table C.3 corrections were interpolated, whether an ISO 11957 insulation carries the prime, whether IEC 61400-11 identified a tone, how ISO 10140-1 J.1 corrected each band of a joint, which IEC TS 61400-11-2 background rule each bin followed, which of Weston's regimes holds at each range, and whether a synchronous average had to interpolate its periods. Each is now a read-only property read from the values the result keeps. Where a result did not keep what its test reads, it does now, with the unit in the name:
TappingForceResultgainsmass_kg,HydrodynamicValveNoisegainsinlet_pressure_paandvapour_pressure_pa,AerodynamicValveNoisegainsspecific_heat_ratio,pressure_recoveryandefficiency_correction,WindTurbineTonalityResultgainscandidate_frequency_hzandLabJointInsulationResultgainslimit_at_maximum, the last three by name only.The numbers a regime selects are held to it when the result is built, so a result built by hand or rewritten with
dataclasses.replacecan no longer carry one regime beside the values of another. A tapping result refuses a cut-off frequency, a limiting frequency, a force spectrum or a power input that K, Zdp and m do not give in their regime. A liquid valve refuses an x_F or an x_Fzp1 that is not Equation (1) or (3c) of the fields beside it, a point at or past flashing, and cavitation fields on a turbulent point or none on a cavitating one. A gas valve refuses boundaries that are not those of its gas and trim, and a Mach number or an acoustical efficiency of another regime. A terrain section refuses a source or receiver that is not a finite point, a source at or past the receiver, a section that does not run from one to the other, and a path difference or diffracting edges that are not its rubber band's. The audiometry results refuse a tracing that keeps no peak or no valley and a mean or threshold the reversals do not give; the Table C.3 correction refuses a value of another gas; the cabin result refuses an A-weighted insulation under any method but the actual noise; the tonality result refuses a candidate that is not a line of the spectrum at or above 20 Hz and a Formula 30 to 34 chain that is not its spectrum's; the joint result refuses a corrected index of another rule; the turbine levels refuse a difference other than total less background, a turbine level of another rule and an uncertainty on an undetermined bin; the Weston result refuses a composite loss that is not the law of the regime in force; and the synchronous average refuses a period grid other than round(fs * period_s). To make that possible the functions now share one helper with their result for each such number, so the function and the check cannot drift apart; Weston's composite loss, for example, is now picked from the same regime labels the property reads.A value exactly on a boundary falls where the source puts it. Hopkins prints the over-critical case as K m ≥ 4 Zdp², so critical damping is over-critical, and IEC TS 61400-11-2 11.7 asks for a total "at least 3 dB" above the background before the logarithmic subtraction. IEC 60534-8-4 does not settle its cavitation threshold one way: the test of 5.1 leaves it to neither side, the region of Equation (9) and Equation (19b) put it with the cavitating points, and 4.1, Equation (18b) and 6.3 with the turbulent ones. The library reads it as turbulent, where Equation (9) returns zero and the two branches meet without a step. The condition printed above Equation (19a) compares x_Fz with x_Fzp1 and names no operating point, and (19a) and (19b) both claim x_F = 1; that is now an errata entry, in English and Spanish.
VibrationReductionResult.band_typestays a field, as the band set the caller states, andvibration_reduction_indexno longer fills it with the set it read from the frequencies; the Annex A mean reads the spacing each time and comes out the same.CriticalCouplingResult.convergedstays a field, because the solve it reports cannot be run again from the result, but it can no longer be claimed beside an absorption that does not exceed 0.999, the third condition of the flag. The test that keeps verdicts out of result fields now also traces a label appended under a comparison, a label written through a mask, a mask narrowed in place and a numbered case a helper returns, and every field that stays is listed with a precise reason: an option the caller states, a branch the caller chose, a fact of an input the result does not keep, a property of the file read, the convergence of a solver, a column of a published table row.What breaks: code that builds one of these results directly, passes one of the removed fields, or replaces one of the fields a regime is read from without the numbers that go with it. Reading the property gives the regime, and the function gives the whole consistent result; the upgrading guide (docs/start/upgrading.md and both site editions) lists each class, the field it no longer takes, what it is read from, what it refuses and the release it first shipped in, with a worked example. Code that read
band_typefromvibration_reduction_indexnow getsNone. The functions take the same arguments and return the same numbers.How it was verified: each boundary was read on the printed page. Hopkins (2007) Eq. 3.95 and the over-critical condition on PDF page 306 (folio 279), Eqs. 3.99 and 3.100 on page 309 (folio 282), Eqs. 3.101 to 3.103 on page 310 (folio 283); BS EN 60534-8-4:2005 Equations (1) and (3c) and 4.1 on PDF page 10 (folio 8), 5.1 and Equation (9) on page 12 (folio 10), (18a) to (19b) on page 14 (folio 12) and 6.3 on page 16 (folio 14); IEC TS 61400-11-2:2024 11.7 on PDF page 40 (folio 38); the NORAH2 guidance Appendix D on PDF pages 41 and 42; ISO 8253-1:2010 6.3.5 on PDF page 19 (folio 11); ISO 10140-1:2021 J.1 on PDF page 44 (folio 38); IEC 61400-11:2012+AMD1:2018 9.5.2 on PDF page 102 (folio 36). The conformance report is unchanged, 1893 of 1893 checks. Every function touched was run over 176 cases (tapping spectra across the over-critical boundary, liquid and gas valves across their regimes, terrain sections from clear to screened, audiometric tracings, Weston grids with and without bottom loss, tonal and flat spectra, background corrections across both limits, joints under both J.1 rules, synchronous averages on and off the sample grid) against the tree before this change, and every field came back bit for bit the same. New tests build each contradicting result and see it refused, and each new refusal was checked by removing it and watching its test fail. The full suite passes (27147 passed, 69 skipped), the documentation snippets pass (7493 blocks over 730 pages), the site builds and validates, and ruff, mypy and bandit are clean.
