Definition

An inquiry is a process that pursues a question. It is written as a tuple (Ξ£, A, π“˜, π“ž, π“š, 𝓑):

  • Ξ£, the language: what the question can be posed in.
  • A, the answer space: which differences would count as an answer. A question q: Ξ© β†’ A partitions states into those it cannot tell apart.
  • π“˜, the admissible interventions.
  • π“ž, the observations: together with π“˜, the operations that make the differences A asks about accessible.
  • π“š, the criteria of evaluation: what makes one candidate answer better than another.
  • 𝓑, the resources: time, computation, records and tools, spent on formulating as well as on answering.

The tuple is A15’s (A, π“˜, π“ž, π“š) of the exchange of 2026-10-27, with the language and the resource bounds that A16 added. Neither called it a standard definition, and it is filed as the record’s own construct.

An inquiry is reflexive when one of its own components becomes what it is pursuing. Revising A is the case CLAIM-470 turns on. A16 Β§4 gives an example: a question about which equilibrium a system occupies must become a question about which attracting set organizes the dynamics, once a Hopf bifurcation leaves a stable limit cycle. Revising π“š is A16 Β§2’s β€œEvaluate or revise ℛ”.

The distinctions it draws

  • From a question. A question fixes A and leaves π“˜, π“ž, π“š and 𝓑 open. β€œIs this system stable?” is a question. It becomes an inquiry once it says which perturbations, which stability, which horizon, how they are observed, and what it may spend.
  • From the regime (TERM-065). The effective-description regime β„› fixes the conditions a description is judged under, and plays the role of π“š together with a fixed query family. An inquiry carries β„› and may revise it. TERM-065 takes β„› as supplied.
  • From the frontier (TERM-092). The inquiry frontier is the set of questions an agent can make into inquiries within its 𝓑. This term is what each member of that set becomes.
  • From specification. That an inquiry stands to its findings as a specification stands to its realizations is CLAIM-470’s thesis. It is stated in this term and is not part of the definition. A reader who rejects the thesis can still use the term.

Why it is proposed

On 2026-10-27 the owner called inquiry a building block of the formal argument. CLAIM-470’s title and proof use it, and so do CLAIM-475’s resource-bounded specifying, TERM-092 and TERM-088’s descriptive sense (β€œan inquiry can distinguish and track it”). Without a definition, each uses its own tuple.

What would settle it:

  • Adoption if CLAIM-470, CLAIM-475 and TERM-092 can each be restated in these six components without remainder.
  • Revision if one of them needs a component the tuple lacks. One candidate is a record of past findings, which CLAIM-470’s stabilizing clause may need apart from Ξ£.
