Drift, Decay & Record Fidelity

Primes about a record, model, or instrument silently losing fidelity to the reality it represents — concept and data drift, evidence-latency and fidelity decay, interpretive drift, unreliable narration — bound together by provenance, close reading, and pipeline mechanics that track or expose the gap.

17 primes in this family — primes that sit near one another in abstraction space (k-means over structural-signature embeddings). Each is shown with its short description.

• Close Reading — The disciplined posture of treating an artefact's smallest meaningful units as load-bearing evidence, suspending paraphrase until the grain is exhausted and binding every higher-order claim to cited marks.
• Concept Drift — A learned rule silently loses validity when the input–outcome relationship it was calibrated on changes underneath it.
• Data Drift — A static learned mapping silently loses accuracy as the deployment distribution drifts away from the distribution it was calibrated on.
• Differential Decay — Two coupled signals decay at different rates, so the surviving component carries forward a meaning the original pair never intended — often with a sign flip.
• Discrepancy-Driven Correction — Iteratively close the signed gap between a target and an observation.
• Evidence-Fidelity Decay — Delay between event and capture lets backfill silently fuse observation, inference, and reconstruction into one uniform record.
• Evidence-Latency Window — A decision must be committed by a deadline while the evidence that would inform it arrives on a separate clock, and the signed gap between the two clocks governs the decision's information state and its repair options.
• Instrument Interpretive Drift — A measurement instrument's interpretive practice silently shifts over time while its stated specification stays fixed, contaminating longitudinal trends.
• Near-Miss Normalization — A system reads the absence of harm in a narrowly-averted event as evidence of robustness rather than as a signal of lost margin, so it resets the margin to the smaller value and drifts its operating envelope toward the failure boundary while still counting itself safe.
• Pipeline — Sequential processing stages.
• Production Signature — A production process involuntarily imprints stable regularities on its output, letting an analyst attribute the output to its source.
• Provenance — A documented, traceable record of an entity's origin and successive custody transfers that establishes authenticity and assigns accountability by linking present state back to first known state.
• Record-Reality Divergence — An authoritative record of an external state drifts from the reality it describes while remaining the basis for downstream decisions.
• Retired Term — A label withdrawn from new use but kept resolvable for existing references, with its retired status and successor publicly marked.
• Signature-Borne Provenance — A conservative property carries origin through transport, read back without a custody chain.
• Silence as Signal — Cost-asymmetric record production makes absence misread as the negative state.
• Unreliable Narrator — A source whose report is systematically distorted relative to the reality it describes, so the receiver must model the distortion rather than read the account as transparent.
