Core Idea

Record-reality divergence is the structural failure in which an information-layer record of an external state — physical, social, or institutional — diverges from the actual state it purports to describe, while remaining the authoritative input to downstream decisions. The record was once accurate; the world has moved; reconciliation has been insufficient to keep the record current; and decisions are now being made on the divergent record, often with results predictable from the divergence direction. The record is the map; the world is the territory; decisions consume the map; and the longer the cadence between updates, the more the map diverges and the more the consuming decisions miscarry. The essential insight is a cache-coherence framing: every authoritative record of an external state is a cache, and every cache requires invalidation. Where invalidation discipline is absent or too slow, the cache drifts and the system behaves as if its picture of the world were true even when it has silently become wrong.

The structural commitment has four pieces. An external state that exists independently of the record — warehouse stock, road network, patient condition, registry entries, employee permissions, threat status. An authoritative record of that state, treated by downstream automation or decision-makers as the operative reference. An update cadence — the rate at which the record is reconciled against reality — which is finite and usually insufficient relative to the state's rate of change. And downstream consumption — decisions, automated processes, or eligibility determinations that treat the record as ground truth and act on it without checking reality directly. The divergence accumulates between reconciliations, often in a directional pattern (consistently overstating or understating), and the failure is invisible until a surfacing event forces the comparison.

How would you explain it like I'm…

The Old Map

Imagine you draw a map of where your toys are, then your toys get moved, but you keep using the old drawing to find them. You go to the wrong spots because your drawing no longer matches the real room. Record-Reality Divergence is when the note about how things are slowly stops matching how things actually are, but everyone keeps trusting the note.

When the List Goes Stale

Suppose a store keeps a list saying how many of each item is on the shelves. The list was right when it was made, but things keep getting sold and restocked, and nobody updates the list fast enough. After a while the list and the real shelves don't match anymore — but the workers still trust the list to decide what to order. Record-Reality Divergence is exactly this: a record that used to be accurate drifts away from the real world it describes, while people keep making decisions from the record without checking reality directly. The longer you wait between updates, the further off the record gets.

The Stale Cache

Record-Reality Divergence is a failure in which an information-layer record of some external state — stock levels, a road map, a patient's condition — drifts away from the actual state it's supposed to describe, while still being the authoritative input that downstream decisions rely on. The record was once accurate, but the world moved, the updates haven't kept pace, and now decisions are being made on a stale record, often going wrong in a predictable direction. A useful way to see it: the record is the map and the world is the territory; decisions consume the map; the longer the gap between updates, the more the map diverges and the more those decisions miscarry. The real insight is a cache-coherence framing — every authoritative record of an external state is a cache, and every cache needs invalidation. Where that invalidation is missing or too slow, the cache drifts and the system acts as if its picture of the world were still true even though it has quietly become wrong.

The divergence accumulates between reconciliations, often directionally (consistently over- or understating), and stays invisible until a surfacing event forces the comparison.

Structural Signature

the independently-existing external state — the authoritative record — the finite update cadence — the downstream consumption — the accumulating divergence with a direction — the cache-coherence invariant — the cadence-to-stakes matching

A configuration exhibits record-reality divergence when each of the following holds:

  • An independently-existing external state. Some physical, social, or institutional state changes on its own clock, independently of any record — stock, road network, patient condition, permissions, threat status. The prime applies only here; where the record constitutes the reality, divergence cannot arise.
  • An authoritative record. A record purports to describe that state and is treated as the operative reference by downstream consumers.
  • A finite update cadence. The rate at which the record is reconciled against reality is finite and usually insufficient relative to the state's rate of change.
  • Downstream consumption. Decisions, automation, or eligibility determinations act on the record as ground truth without checking reality directly.
  • Accumulating directional divergence. Between reconciliations the record drifts from the state, often in a consistent direction (overstating or understating), with direction-specific failure modes; the failure is invisible until a surfacing event forces comparison.
  • The cache-coherence invariant. Every authoritative record of an external state is structurally a cache requiring an invalidation strategy; absent or too-slow invalidation, it drifts. This framing imports the intervention vocabulary — source-of-truth, write-through versus write-back, freshness metadata.
  • Cadence-to-stakes matching. Reconciliation cadence and decision stakes scale together: low-stakes decisions tolerate stale records, high-stakes ones require near-real-time reconciliation or direct reality checks.

These components compose into a coherence diagnosis: an authoritative cache of an independently-changing state, reconciled too slowly and consumed as if current, drifts directionally — repaired by matching invalidation discipline to decision stakes.

What It Is Not

  • Not a record of origin (see provenance). provenance documents where a record came from — its lineage and chain of custody; record-reality divergence concerns whether the record is currently accurate about an external state. Perfect provenance says nothing about currency; a fully-traceable record can be badly stale.
  • Not traceability (see traceability). traceability is the ability to follow a record back to its sources or forward to its uses; divergence is the gap between record and present reality. Traceability links records; it does not keep them current.
  • Not physical decay of the referent (see temporal_decay_and_degradation). temporal_decay_and_degradation is the reality itself degrading over time; record-reality divergence is the record falling out of sync while reality changes (which may or may not be decay). The thing drifting is the map, not the territory.
  • Not a drifting standard (see reference_standard_decay). reference_standard_decay is the erosion of the yardstick against which things are measured; divergence is the erosion of a record's match to a state. One corrupts the unit of measure; the other corrupts a specific cached value.
  • Not data-entry error or measurement noise. The record was once accurate and reality has moved; this differs from a record that was wrong at entry (data quality) or statistically uncertain (noise). Each has a different fix — and lumping all three as "bad data" misdiagnoses divergence.
  • Common misclassification. Trusting a record more over time because nothing has surfaced an error. Catch it by asking what mechanism would surface a divergence and how long it would take; if the only detector is a downstream catastrophe, silence is the normal state of an undetected drift, not evidence of currency.

Broad Use

  • Warehouse and retail inventory (phantom inventory) — stock records diverge from physical counts through shrinkage and mis-scans; replenishment algorithms under- or over-order based on the divergence direction.
  • Software supply chain — lockfiles point at registry artefacts that have been yanked, replaced, or namespace-attacked; build systems install the wrong code.
  • Geographic information systems — dispatch maps show roads that no longer exist or bridges that are closed; routing decisions consume the bad map.
  • Public-health case registries — reported counts diverge from true incidence through reporting lag; policy decisions are biased by the divergence.
  • Government registries — voter rolls, property records, and licences carry stale entries; eligibility and taxation decisions consume them.
  • Financial books — front-, middle-, and back-office records diverge when reconciliation is delayed; risk and capital decisions consume divergent books.
  • Patient electronic-health records — allergy and medication lists drift from clinical reality; ordering and decision-support consume the drifted record.
  • Identity and access-control records — who-has-access diverges from actual employment and role as changes propagate slowly, producing over- and under-permission.
  • Surveillance and threat databases — watchlists carry stale entries; checks consume them with consequences from false detentions to missed threats.
  • Cartographic datums — spatial references drift as tectonic motion accumulates; positions anchored to old datums are silently wrong.

Clarity

Naming record-reality divergence separates three commonly fused failures: data quality (the record was wrong when entered), measurement noise (the record is statistically uncertain), and divergence (the record was once accurate but reality has moved and reconciliation has not kept up). Each has a different fix: data quality calls for better entry validation; measurement noise calls for filtering and averaging; divergence calls for reconciliation cadence, anomaly-driven audit, and write-through-versus-write-back semantics. Without the distinction, all three are lumped as "the data is bad" and the appropriate fix is misidentified.

The clarifying force is the cache-coherence framing: every authoritative record of an external state is structurally a cache, and every cache requires an invalidation strategy. Many failures across substrates — phantom inventory, stale watchlists, drifted patient records, expired access permissions — are recognizable as the same class of cache-coherence failure once the framing is applied. The intervention vocabulary then ports: source-of-truth designation, reconciliation cadence, exception-detection on inferred-versus-record mismatch, and treating any record of external state as a cache requiring an invalidation policy. The framing also exposes a subtle point: the existence of an authoritative record is itself a claim of currency that the system may not be entitled to make, and downstream consumers assume the record is current precisely because it is authoritative.

Manages Complexity

The arrangement compresses a sprawling list of substrate-specific failures — phantom inventory, lockfile drift, stale registries, drifted patient records, expired access controls, stale watchlists, position-book divergence — into one structural pattern with reusable parts: external state, authoritative record, update cadence, downstream consumption, divergence direction. The analyst asks the same questions in any substrate: what is the external state; what is the authoritative record; what is its update cadence; what reconciles record against reality, and how often; what decisions consume the record; what is the divergence direction, and what failure mode does it produce?

The intervention space sorts cleanly. Increase reconciliation cadence — more-frequent counts, audits, or reviews. Add exception-detection — anomaly detection on inferred-versus-record mismatch that triggers targeted reconciliation. Change the source-of-truth designation — let reality, observed at decision-time, override the record for high-stakes decisions. Switch from write-back to write-through semantics — update the record synchronously rather than in delayed batches. Add provenance and freshness metadata so consumers can decide whether the record is fresh enough to act on. The leverage is that cadence and stakes scale together: low-stakes decisions tolerate stale records, while high-stakes decisions require near-real-time reconciliation or direct reality checks, so the analyst can match cadence investment to decision stakes rather than reconciling everything at one uniform rate.

Abstract Reasoning

Record-reality divergence trains a reasoner to ask:

  • What is the external state, and does it exist independently of the record and change on its own clock?
  • What is the authoritative record, and is it treated as ground truth by downstream consumers without direct reality checks?
  • What is the update cadence, and is it sufficient relative to the state's rate of change?
  • What is the divergence direction — consistently overstating or understating — and what failure mode does each direction produce?
  • Is this a cache without an invalidation strategy, and which intervention applies: increase cadence, add exception-detection, change source-of-truth, switch to write-through, surface freshness metadata?
  • Do the stakes of the consuming decision justify the reconciliation cadence, or is cadence mismatched to stakes?

The portable inferences are that the divergence direction is consequential — a record that overstates produces different failure modes than one that understates, and whichever direction is penalized most heavily determines the needed cadence; that cadence and stakes scale together; that cache invalidation is the binding constraint, since building the record was the visible work while keeping it current is the expensive ongoing work; and that trust in the record is a load-bearing assumption that, once lost, reverts the system to impractical manual lookup. A subtler inference is that the existence of an authoritative record creates a moral hazard: consumers assume currency because the record is authoritative, even when no mechanism guarantees it.

Knowledge Transfer

Role mappings across domains:

  • External state ↔ physical stock / road network / patient condition / registered party status / employment status / threat status
  • Authoritative record ↔ ERP stock level / dispatch map / EHR medication list / voter roll / access-control entry / watchlist
  • Update cadence ↔ cycle count / map refresh / medication reconciliation / registry audit / permission review
  • Downstream consumption ↔ replenishment algorithm / routing decision / clinical order / eligibility check / authentication
  • Divergence direction ↔ consistent overstating or understating, with direction-specific failure modes
  • Cache framing ↔ source-of-truth, reconciliation cadence, write-through versus write-back, freshness metadata

An inventory manager fighting phantom stock, a dispatcher routing on a stale map, a clinician reconciling a drifted medication list, and an identity engineer revoking stale credentials are reasoning about the same structure: an authoritative cache of an external state whose update cadence is insufficient relative to the state's rate of change, consumed downstream as if current. The transfers among substrates are documented and direct. The formal cache-invalidation framework from computer architecture transfers cleanly to government-registry maintenance with the same vocabulary — read-through, write-back, time-to-live, invalidation, dirty bits. The cycle-counting discipline from retail inventory ports into periodic access-control audits with the same cadence-versus-cost trade-off and statistical sampling. The discipline of treating map data as stale-by-default ported from GIS into AI training-data freshness regimes. Bullwhip-effect analysis from supply chains transfers into general analysis of how divergent records amplify through staged consumers. Medication-reconciliation discipline from clinical safety transferred into financial-position reconciliation, with the same insistence on cross-checking records against external reality at high-stakes transition points. The non-transfer caveat is that where the external state is defined by the record — legal status, normative classification, membership in a constructed category — divergence does not arise, because the record is the reality by constitutive authority; the prime applies only where the external state has independent existence the record purports to track. What moves between fields is the literal cache-coherence framing — record as cache, invalidation as the binding discipline — together with its intervention catalogue (reconciliation cadence, exception detection, freshness metadata, source-of-truth designation), recognizable wherever a record drifts from a world it describes while still steering decisions.

Examples

Formal/abstract

A processor cache is the prime's namesake and its cleanest formal instance. The independently-existing external state is the authoritative value of a memory location in main memory (or, in a multicore system, the value other cores may write). The authoritative record is the cached copy a core holds in its local cache line and treats as operative — it reads and computes from the cache, not from memory, without checking reality directly (downstream consumption). The finite update cadence is whatever invalidation traffic the coherence protocol generates: between invalidations, the cached line can diverge from the true memory state once another core writes. The accumulating directional divergence is concrete — a stale read (cache understates a value that has since been incremented elsewhere) versus a lost update (cache overstates because a write-back has not yet propagated), each a direction-specific failure mode. The cache-coherence invariant is not a metaphor here but the literal subject matter: protocols like MESI exist precisely because every cached copy of an external state requires an invalidation strategy. The intervention vocabulary the prime imports — source-of-truth (which copy is authoritative), write-through versus write-back (synchronous update to memory versus deferred), dirty bits and freshness metadata (marking a line as diverged) — are exactly the design knobs of cache architecture. And cadence-to-stakes matching appears as the consistency-model choice: relaxed/eventual consistency tolerates staleness for speed where the stakes are low, while strong consistency forces near-synchronous reconciliation where correctness is critical.

Mapped back: The cached line is the authoritative record, the true memory value is the independently-changing external state, stale reads and lost updates are directional divergence, MESI is the invalidation strategy the cache-coherence invariant demands, and write-through-versus-write-back with relaxed-versus-strong consistency is cadence-to-stakes matching — the prime stated in its origin substrate.

Applied/industry

Phantom inventory in retail and stale access controls in security are the same coherence failure in two industries. In a warehouse, the external state is the physical stock actually on the shelf, which changes on its own clock through sales, theft, damage, and mis-shelving; the authoritative record is the ERP system's stock level; the update cadence is the cycle-count schedule; and downstream consumption is the automated replenishment algorithm that reorders based on the record without looking at the shelf. Directional divergence is the diagnostic crux: shrinkage and mis-scans make the record overstate real stock, so the algorithm under-orders, producing silent stock-outs the system cannot see because its picture says inventory exists — the failure stays invisible until a surfacing event (a customer finds an empty shelf the system says is full). The repair kit is the prime's: increase cadence (more frequent cycle counts), add exception-detection (flag SKUs whose sales pattern implies a different stock level than recorded, triggering a targeted count), and match cadence to stakes (count high-value, fast-moving SKUs more often). Identity and access management instantiates the identical structure: the external state is who actually should have access given current employment and role; the authoritative record is the access-control list; the cadence is the permission-review cycle; consumption is real-time authentication granting entry on the record alone. Here the consequential direction inverts — the dangerous divergence is the record overstating entitlement (a departed employee whose access was never revoked retains live credentials), so the security stakes push cadence toward continuous reconciliation and event-driven write-through (deprovision synchronously on the HR termination event rather than waiting for the quarterly review).

Mapped back: ERP stock levels and access-control lists are authoritative caches of independently-changing external states (physical stock, true entitlement); cycle counts and permission reviews are the update cadence; replenishment algorithms and authentication checks are downstream consumers acting on the record as ground truth; and over-stating stock causing stock-outs versus over-stating access causing security holes are the direction-specific failure modes that set the required cadence across a retail and a security substrate.

Structural Tensions

T1 — Update Cadence versus State Change Rate (Temporal). Divergence accumulates between reconciliations at the state's rate of change, so the binding relationship is cadence relative to that rate — a record refreshed daily is fresh for a monthly-changing state and badly stale for a per-second one. The failure mode is fixing cadence by convenience or legacy rather than by the state's clock, so a record nominally "updated regularly" is chronically divergent because the world moves faster than the schedule. Diagnostic: compare reconciliation interval against the state's characteristic change time; if the state turns over several times per update, the record is stale on average regardless of how dutifully the schedule is kept.

T2 — Divergence Direction Asymmetry (Sign/Direction). Overstating and understating are not symmetric — each produces a distinct failure mode, and usually one direction is far more costly (overstated stock causes silent stock-outs; overstated access causes security holes). The failure mode is treating divergence as undirected "data error" and reconciling uniformly, under-protecting against the dangerous direction. Diagnostic: ask which direction the record tends to drift and which direction is penalized most heavily; if they coincide, cadence must be set by the costly direction alone, and a symmetric reconciliation policy that ignores the asymmetry will be over-cautious on the cheap side and under-cautious on the expensive one.

T3 — Authoritativeness versus Currency (Coupling). The record's authority is a claim of currency the system may not be entitled to make, and downstream consumers trust it because it is authoritative — a moral hazard. The failure mode is authority-induced complacency: consumers act on the record without a reality check precisely because it is the designated source of truth, so the more authoritative the record, the more confidently wrong decisions ride on its staleness. Diagnostic: ask whether anything actually guarantees the record's currency or merely its authority; if authoritativeness is doing the work that a freshness guarantee should, attach explicit freshness metadata so consumers can distinguish "official" from "current."

T4 — Cadence Cost versus Decision Stakes (Scalar). Reconciliation is expensive and stakes vary, so cadence and stakes must scale together — uniform reconciliation either overspends on low-stakes records or underspends on high-stakes ones. The failure mode is one-rate-fits-all: counting every SKU or reviewing every permission on the same schedule, leaving the high-value, fast-moving, high-consequence records exactly as stale as the trivial ones. Diagnostic: ask whether cadence is differentiated by the consuming decision's stakes; if a catastrophic-if-wrong record reconciles at the same rate as a cosmetic one, the cadence budget is mis-allocated, and the fix is stake-weighted cadence, not more uniform effort.

T5 — Constituted Reality versus Tracked Reality (Scopal). The prime applies only where the external state exists independently and the record tracks it; where the record constitutes the reality (legal status, membership in a constructed category, normative classification), divergence cannot arise because the record is the territory. The failure mode is mis-applying coherence machinery to a constitutive record — chasing "the real underlying status" behind a legal designation that has no existence apart from the register, or, inversely, treating a tracking record as constitutive and refusing to check reality because "the record says so." Diagnostic: ask whether reality could disagree with the record; if the record's say-so makes the fact, there is nothing to reconcile, and if reality can diverge, the record is a cache and must be treated as one.

T6 — Silent Drift versus Surfacing Event (Temporal). Divergence is invisible until a surfacing event forces the comparison, so the system runs on a confidently-wrong picture for an unknown interval before discovery. The failure mode is mistaking absence of detected error for currency: trusting a record more over time because nothing has surfaced, when the quiet is just the gap between drift and its eventual revelation. Diagnostic: ask what mechanism would surface a divergence and how long it would take — if the only detector is a downstream catastrophe (the empty shelf, the breach), the record has no early-warning and exception-detection on inferred-versus-record mismatch must be added, since silence is not evidence of coherence but the normal state of an undetected drift.

Structural–Framed Character

Record-Reality Divergence sits on the structural side of the structural–framed spectrum, consistent with its frontmatter label of structural and a low aggregate of 0.2: a mostly clean information-state pattern — a cache drifting from the territory it tracks — with a modest bias toward administrative-record substrates that keeps it just off zero.

The structural mass dominates. The home vocabulary travels unmodified (vocab_travels 0.0): the cache-coherence framing — source-of-truth, write-through versus write-back, invalidation, freshness metadata, dirty bits — maps cleanly from a processor cache to ERP stock levels, dispatch maps, EHR medication lists, voter rolls, and access-control entries, and the formal MESI logic is the prime stated in its origin substrate. The prime carries no evaluative weight (0.0): a stale record is a correctness failure, not a moral one, and the divergence direction is diagnosed, not condemned. Invoking it recognizes a map-territory currency gap already present (import_vs_recognize 0.0) rather than importing a frame.

What lifts the aggregate off zero is a half-weight on two axes: institutional_origin and human_practice_bound at 0.5 each. Many of the load-bearing instances — voter rolls, property registries, EHRs, watchlists, access-control lists — are administrative records embedded in human institutions, which biases the prime's center of gravity toward sociotechnical substrates even though the mechanism itself (a processor cache, a cartographic datum drifting under tectonic motion) runs in purely physical ones. That bias is a pull, not a relocation: the underlying currency-of-a-cache pattern is genuinely structural and recognized wherever a record drifts from an independently-changing state it describes. The clean cache-coherence core against a mild administrative-record lean is exactly what the structural 0.2 records.

Substrate Independence

Record-Reality Divergence is a highly substrate-independent prime — composite 5 / 5 on the substrate-independence scale. The domain breadth is exceptionally wide and the structural force identical: the cache-coherence pattern — an authoritative record drifting from the external state it caches because update cadence lags the state's change rate — recurs in warehouse and retail inventory (phantom inventory), software supply chains (yanked or replaced lockfile artefacts), geographic information systems (stale dispatch maps), public-health case registries (reporting lag), government registries (voter rolls, property records), financial books (delayed reconciliation), patient electronic-health records (drifted allergy lists), identity and access-control records (stale permissions), surveillance and threat databases (stale watchlists), and cartographic datums (tectonic drift). The transfer evidence is strong because the vocabulary maps cleanly onto cache invalidation — every authoritative record is a cache, every cache needs invalidation — and that single framing carries across all these substrates as a working diagnostic. The structural abstraction is recorded at 4 rather than 5 because the schema always presupposes a record-of-an-external-state consumed by downstream decisions — a slightly committed information-system shape rather than a bare formal relation — which is why that one sub-score sits a notch below the maximal breadth and transfer.

  • Composite substrate independence — 5 / 5
  • Domain breadth — 5 / 5
  • Structural abstraction — 4 / 5

Not to Be Confused With

Record-reality divergence is most easily confused with provenance, its embedding-nearest neighbor (similarity 0.871), because both concern the trustworthiness of a record. But they answer orthogonal questions. provenance is about origin and lineage: where did this record come from, through what chain of custody, derived from what sources — a backward-looking account of how the record came to be, used to establish authenticity and authority. Record-reality divergence is about present currency: regardless of how impeccable its lineage, does the record still match the external state it describes right now? The two are independent in both directions. A record can have flawless provenance (every edit logged, every source cited, custody never broken) and yet be badly divergent (the warehouse count was perfectly recorded last month and the shelf has since emptied). And a record can have murky provenance yet happen to be current. This independence is consequential because provenance systems can induce the very complacency the prime warns about: a record with strong provenance feels authoritative, and authoritativeness is precisely the claim-of-currency the system may not be entitled to make. A practitioner who treats good provenance as evidence of accuracy will trust a well-sourced but stale record, missing that lineage certifies how the cache was filled, not whether the cache is still valid — which is the invalidation question provenance never asks.

Record-reality divergence is also confused with traceability, which is adjacent to provenance and equally orthogonal to currency. traceability is the structural property of being able to follow links — from a record back to its inputs, or forward to the decisions and artefacts derived from it — so that a change or fault can be traced through the chain. It is a property of the linkage graph among records and reality, valuable for impact analysis and audit. Record-reality divergence is a property of the match between one record and the present state of its referent. A fully traceable system — where every record's dependencies and dependents are known — can still suffer pervasive divergence, because traceability tells you what consumes a stale record (and thus how far the staleness propagates, the bullwhip concern) but does not by itself keep the record fresh. Indeed traceability and divergence interact precisely at propagation: good traceability lets you find everything downstream of a divergent record once you know it has diverged, but it provides no invalidation signal of its own. Conflating the two leads to investing in linkage instrumentation (so failures can be traced after the fact) while neglecting reconciliation cadence (so failures keep occurring), addressing the spread of staleness rather than its source.

A more substantive confusion is with reference_standard_decay, because both involve something authoritative drifting over time. The distinction is what drifts and what it does to measurement. reference_standard_decay is the erosion of the standard itself — the yardstick, the calibration reference, the canonical definition against which other things are measured — so that everything measured against it becomes systematically mis-scaled in a correlated way. Record-reality divergence is the drift of a specific record's value away from a specific external state, while the measuring framework stays sound. The failure topologies differ: a decaying reference standard corrupts all measurements taken against it simultaneously and coherently (every length is now slightly off because the metre-bar shrank), whereas record-reality divergence corrupts individual cached values idiosyncratically (this SKU's count is wrong, that one's is fine). The repairs differ accordingly: reference-standard decay is fixed by recalibrating or redefining the standard (and propagating the correction), while divergence is fixed by reconciling particular records against reality (cycle counts, audits, write-through on events). A practitioner who mistakes divergence for standard decay will hunt for a systematic mis-scaling when the problem is scattered stale entries; one who mistakes standard decay for divergence will reconcile individual records one by one while the shared yardstick that corrupts them all goes unaddressed.

These distinctions matter because each isolates the prime's actual content — currency of a cache relative to an independently-changing state — from properties that feel like data-trustworthiness but are not currency. provenance certifies origin; traceability maps linkage; reference_standard_decay corrupts the shared yardstick. Record-reality divergence asks only whether this record still matches the world it describes, and its cache-coherence framing supplies the intervention vocabulary — invalidation cadence, write-through versus write-back, freshness metadata, source-of-truth — that none of the neighbors provide. Keeping it distinct is what stops a practitioner from trusting a well-sourced, fully-traceable record that has silently gone stale.
