Owner

Parent epic: #13
Depends on: #23
Refines: #6

Goal

Build rebuildable current/history views over canonical append-only semantic history.

Implement:

explicit valid_at vs known_at query coordinates;
current-active resolution for supersession/retraction/invalidation/temporal expiry;
historical cut queries preserving what was known at a past frontier;
conflict plurality instead of last-write-wins;
projection generation/freshness metadata;
deterministic rebuild from canonical ledger;
stale-view rejection when query requires exact current state.

Acceptance

Fixtures prove historical truth vs historical knowledge are distinct; correction today can alter today's view of past validity without rewriting what the system knew yesterday; retraction does not synthesize negation; cache/view deletion followed by rebuild yields equivalent normalized results.
