Temporal, version, and supersession graph

Researched designNot deployed
Question§
Which fact or instruction applied at the relevant time?
Nodes§
Claim; Document version; Effective interval; Observation; Supersession
Relationship sketch§
- version → superseded version
- claim → applicable interval
- observation → collected time
Evidence inputs§
Actual publication/effective dates, revision records, retrieval date, scope decisions.
Implementation§
Store effective time separately from observation time. Keep historical claims for historical questions while blocking them from current instructions when superseded.
Acceptance checks§
- An unknown effective date stays null
- Current retrieval respects supersession
- A review date is not substituted for a publication date
Do not infer§
Newer text is not automatically more authoritative than older applicable evidence.
Publication boundary§
Public revision notes as appropriate; internal record history private.
