Neutrino hypothesis support

Require positive compatibility evidence and explicit alternatives before accepting the classification.

1. Which production or interaction observations support a neutrino interpretation? definition
2. Which photon, neutron, unseen charged-particle or instrumental explanations remain viable? boundary

Contextual species assignment

Record each species label with its production or detection context and unresolved alternatives.

1. Does the flavour label describe production, detection or a predicted intermediate state? definition
2. Which parent process or final-state charge measurement supports the neutrino or antineutrino label? provenance
3. Must the assignment remain probabilistic because the available channel cannot distinguish the alternatives? boundary

Parent process constraints

Identify which source evidence constrains the initial flavour, energy and emission time.

1. Which decay, nuclear reaction or collision is proposed to have produced the neutrino? provenance
2. Is the association supported by a tagged parent, beam timing, directional coincidence or a population model? measurement
3. Which alternative sources remain compatible with the timing and direction uncertainties? boundary

Incoming state estimate

Record energy, direction and timing estimates together with the assumptions that produce them.

1. How is incoming neutrino energy inferred from visible products, missing energy and target recoil? measurement
2. What joint uncertainties and reaction assumptions accompany the reconstructed energy and direction? measurement
3. Does the evidence support an individual candidate estimate or only an ensemble distribution? boundary

Propagation state contract

Make basis, coherence assumptions and mixing inputs explicit before calculating a transition probability.

1. Is the initial state represented by flavour amplitudes, mass amplitudes or an incoherent mixture? definition
2. Which dated mixing-parameter fit, mass-ordering assumption and parameter correlations are used? provenance
3. Do production localization, energy resolution and baseline justify coherent evolution or averaging? boundary

Transition probability validity

Bound the calculation by path uncertainty, medium assumptions and the selected evolution approximation.

1. What baseline distribution and electron-density profile describe the proposed path? measurement
2. Are vacuum evolution, ordinary matter effects and coherent propagation sufficient for this regime? boundary
3. Which arrival-flavour probabilities can be calculated, and how must input uncertainties be propagated? action

Channel and target compatibility

Select reaction hypotheses and interaction estimates with an explicit domain of validity.

1. Which charged-current or neutral-current reactions are accessible for this energy, species and target? boundary
2. Which cross-section calculation or measurement applies, including target composition and uncertainty? provenance
3. What interaction probability follows from the target column density and applicable cross section? measurement

Candidate identification strength

Link observed products to identification confidence while preserving detector and background limitations.

1. Which tracks, showers, recoil signals or delayed coincidences support the proposed reaction? measurement
2. What flavour and neutrino-versus-antineutrino discrimination does this signature support? boundary
3. Should the agent accept, retain as ambiguous or reject the candidate after background and efficiency assessment? action

Mass constraint applicability

Require an identified observable before a mass result is used in a decision.

1. Does the result constrain an individual mass, a squared-mass difference, an effective decay mass or a cosmological mass sum? definition
2. Which confidence convention, dataset and theoretical assumptions accompany the result? provenance
3. Which conclusions about this neutrino state are justified by that observable? boundary

Hypothesis-dependent actions

Separate calculations under an extension from accepted identity claims.

1. Does the interpretation require sterile mixing, neutrino decay, a magnetic moment or lepton-number violation? definition
2. Which evidence constrains the proposed extension, and which competing explanations remain? provenance
3. Which predictions may be explored conditionally, and which identification claims must remain withheld? action
