Side-by-side matrix

Currentness and Availability are related but not interchangeable
DimensionCurrentnessAvailability
Primary questionWhat evidence establishes the first property for a named purpose?What separate evidence or authority establishes the second property?
EvidencePurpose-specific technical, factual, or institutional records.Independent records appropriate to the second category.
AuthorityMay be descriptive or technical and may not require legal authority.May require a competent legal, constitutional, organizational, or operational decision-maker.
CurrentnessCan be current, stale, disputed, unknown, or unavailable.Must be assessed separately; the first status does not transfer.
Failure conditionEvidence may be authentic but incomplete or unsuitable.Authority may exist but rely on wrong or stale facts.

Why the distinction matters

Currentness asks whether the identified edition remains appropriate for the claim and date; availability asks whether a resource can be retrieved. Systems and institutions fail when one side is used as a shortcut for the other. The distinction determines what evidence is collected, who may decide, what can be appealed, and which failure modes must be controlled.

Common failure caused by conflation

Assuming that an HTTP 200 response means a standard, law, or guidance page is still active and authoritative.

This error can create false confidence, unauthorized status, misattributed liability, silent loss of correction rights, or an operational claim based only on descriptive material.

Implementation consequences

  • Use different fields, identifiers, and claim-status records for each side.
  • Require separate evidence and currentness checks.
  • Do not let a user-interface label silently merge the categories.
  • Preserve correction and supersession history for both.
  • Route decisions to the ecosystem authority that owns the relevant function.

Legal admissibility and weight depend on jurisdiction, procedure, foundation and purpose; technical validity is not a universal admissibility rule.

Technical evidence can inform a legal decision but cannot replace jurisdiction, legal basis, procedural authority, due process, or remedy. Conversely, a lawful decision does not make the underlying technical record accurate if the evidence is stale or defective.

Examples

  1. A valid signature demonstrates control over a key and payload integrity; it does not establish the truth of every signed statement.
  2. A registry can record a citizenship decision; the registry operator does not thereby acquire constitutional power to create citizenship.
  3. A static release can show that software exists; it does not prove the service is currently operating.

Comparison claim record

Each proposition has a stable ID, status, scope, owning route, evidence relationship, currentness qualification, correction state, and synchronized JSON record. Record completeness does not make the proposition true.

Currentness versus Availability

Currentness asks whether the identified edition remains appropriate for the claim and date; availability asks whether a resource can be retrieved.
