Validation is the systematic process of establishing that a thing meets specified requirements or criteria. Its parameters are: (1) a defined set of acceptance criteria that specify what counts as valid, (2) an evaluation method — testing, inspection, or analysis — that applies those criteria to the thing being validated, and (3) a recorded outcome (pass/fail or graded conformance) that persists beyond the evaluation act itself. Validation differs from verification in that it answers whether the right thing was built (conformance to needs and intended use) rather than whether the thing was built right (conformance to specifications). It persists through documentation of criteria, records of evaluation, institutionalized procedures, and the social practice of requiring validation before deployment.

Definition
Why it is in scope
A human-made process: systematically establishing that a thing meets specified requirements or criteria through defined evaluation methods. Built to persist through documentation, records of conformance, and institutionalized verification procedures that outlast any single evaluation act.

- cmrnaoqvi0227d1nlvj8ojuxzDEPENDS_ON →
Validation operates by measuring against established criteria. Remove criterion and validation has nothing to validate against — it loses its standard for judgment.
- cmrmlc1rs00l6d1nlca3uac2cINSTANCE_OF →
Validation IS a specific kind of verification: both check correctness, but validation specifically checks against criteria/standards. Law 9: a competent speaker would call validation a kind of verification. Direction correct (specific→general).
- cms7wyk72004ph6s8d82lhwqlDEPENDS_ON →
Validation depends on reliability: verifying something works correctly requires that repeated tests yield consistent results. Remove reliability and validation cannot distinguish genuine failures from random noise.

TESTED: remove validation as a concept and k-fold CV stops operating — it IS a validation procedure. Without the concept of validation, k-fold has no purpose or operation. The method's whole point is to validate model performance.

Cross-validation is a specific method of validation — a competent speaker would call cross-validation 'a kind of validation.' Per Law 9, specific→general.
- cmsli0x7x076bnobp5cbkmn1x← DEPENDS_ON
Early stopping operates by comparing validation loss across epochs and halting training when it stops improving. Remove validation metrics and early stopping as a training practice stops functioning — there is no signal to act on. Removal test passes.
- input-validation← INSTANCE_OF
Input validation — checking that input data conforms to expected format, range, type, or constraints before processing — is a specific kind of validation. A competent speaker would call input validation 'a type of validation.'
- cms4x8mt0004ti9iq1eaz9m56← DEPENDS_ON
Corroboration is the practice of providing independent supporting evidence to confirm a claim. Validation is the systematic process of checking accuracy. Corroboration operates within the validation framework — remove validation and corroboration loses its purpose (confirming claims as part of a verification process). Direction correct (validation older at 0.14, corroboration at 0.23).
