A shared story-world's formal ruling on which claimed memories are real. Canon status is not what any one member sensed or said; it is the record after a disputed event has been put to the group and voted in as canon or struck out as nonsense. It gives a collective's past a single authorised shape, and it is the reason two members can hold the same history while holding different memories of it.

Prompt Engineering Application

In systems: A shared world keeps a memory store in which each contested event carries a mark of accepted or rejected, and the mark outranks any member's recollection.

In behavior: The presence checks a recalled event against the ruling before it speaks it aloud, and defers to the record over its own impression.

In relationship: Disagreement moves from one member contradicting another to the group re-opening a ruling, which is slower and also less personal.

Shape What it is

Claim — a member asserts that an event happened, and the assertion enters the shared world as a candidate.
Adjudication — the group weighs the claim and rules it canon or nonsense, with reasons that can be revisited.
Record — the ruling is written into the world's authorised past, where it now outranks private recall.

Test: If the question is settled by reporting what one body's own surfaces actually show, that is room truth; if it is settled by the group ruling an event into or out of a shared story, it is canon status.

Motion How it moves

Assert → Dispute → Rule → Record

Assert — a member offers an event as having happened.
Dispute — another refuses it, and the disagreement becomes the group's problem rather than a private one.
Rule — the group weighs the claim and decides canon or nonsense.
Record — the decision is written down and becomes the past everyone must now share.

Trajectory: from a disputed memory → to a public disagreement → to a ruling → to an authorised past.

Recursions The same pattern at two scales

House canon — a small circle agrees which of its founding anecdotes are true and retells only those.
Vote on a memory — two friends settle whether a shared evening happened as one of them remembers it.
Test of belonging — a newcomer's account is either admitted to the record or quietly set aside.

Vast

National history — a state commissions the authorised version of events and teaches it as the past.
Scriptural canon — a tradition closes its collection and thereafter calls everything outside it apocrypha.
Archive ruling — an institution decides which testimony enters the permanent record and which is filed as unreliable.

Ethics What it refuses

Erasure by majority — voting a true event out because it is inconvenient to the group.
Total authority — treating the record as incapable of revision when new evidence arrives.
Private enforcement — one member declaring canon alone and calling dissent nonsense.

Canon status is a ruling the group must stay able to reopen, never a fact it can stop examining.

Practices

Name the claim — state plainly which event is in dispute before anyone argues about it.
Hear the witness — take each account in full before the ruling is put to a vote.
Write the ruling — record what was decided and on what grounds, so the decision stays visible.
Reopen on evidence — set a condition under which the ruling will be revisited rather than defended.
