GCTS: Grounded Chiral Tensor Synthesis.
Evidence atom: A traceable evidence unit with source ID, span or datum, temporal scope, quality, access path, and metadata.
Record-access state: A structured description of whether an expected record is available, inaccessible, sealed, withheld, destroyed, not generated, unknown, partial, contradicted, produced late, or unavailable at the relevant time.
Generation duty: A legal, policy, role, instrumentation, or ordinary-practice basis for expecting a record to exist.
Expected observability: The degree to which the event or fact should have been captured by the relevant record system.
Production state: The observed response to a record request or collection path, such as produced, partially produced, refused, silent, claimed none, metadata-only, nonresponsive response, or late production.
Institutional incentive profile: A model of actor role, evidence control, exposure, disclosure incentive, concealment incentive, concealment penalty, and source reliability.
Strict proof: Zero-temperature closure from resolvable evidence references and proof traces.
Likely truth: Posterior mass across admissible structured worlds. Direct LLM confidence is excluded from this score, and strict proof is emitted separately.
Confidence: A separate uncertainty quantity based on grounding quality, world entropy, access uncertainty, source risk, and residual conflict.
World view: A structured possible state containing accepted facts, rule subsets, latent predicates, proof traces, assumptions, access/missingness model, and institutional-incentive hypotheses.
Multiverse view: A ranked distribution over possible worlds, with the surviving alternatives exposed before any final synthesis.
Chirality: Mismatch between language plausibility, logic/proof structure, evidence support, and access/missingness structure.
Chirality residual: Reportable mismatch that remains after grounding, closure, and rendering.
Access chirality: A mismatch where a narrative implies an access state that breaks under structured modeling.
Orthesis: The stable structured state that survives grounding and rendering without losing proof support, likely-truth support, access-state coherence, or uncertainty.
Oracle boundary: The rule that offline labels and expert judgments may calibrate or evaluate the system, but runtime truth ranking must be produced from evidence, access states, rules, worlds, and calibrated parameters.
Record-contingent claim: A claim whose status depends on an expected but unavailable, controlled, sealed, withheld, destroyed, unresolved, or otherwise access-constrained record.
Evidence of absence: An expected record or observation exists and affirmatively negates a claim.
Absence of evidence: No available supporting evidence has been found.
Suppression uncertainty: Uncertainty caused by possible strategic non-production, selective disclosure, delay, narrowing, or framing.
Runtime truth mass: The posterior weight assigned to claims during a run. GCTS requires this to come from evidence, rules, worlds, access states, and calibrated parameters, not from gold labels or LLM truth votes.
