Answer lifecycle
How this DID page changes over time
Before the date
Answer remains no
Upcoming records point users to /countdown/anthropic-claude-build-2026/ when the canonical countdown is still inside the index window.
On the date
Date-current answer
The static answer avoids claiming completion by hour when no verified end state is stored; use the source for live access or release status.
After the date
Answer flips to yes
The page becomes an archived yes/no answer and keeps source, date, entity, and nearby-event context together.
30-day archive boundary
Still inside index window
Older DID answers remain reachable for users and internal context but leave the index after 30 days to avoid stale long-tail clutter.
Claim boundaries
What the yes/no answer does and does not claim
What the answer proves
It compares the retained event date for Anthropic Claude Build Conference 2026 with a static decision date and answers the direct did-it-happen query.
What it does not prove
It does not confirm ticket access, livestream availability, release rollout timing by region, venue admission, cancellation handling, or local time unless those fields are explicitly stored.
When to use the source
Use anthropic.com for late changes, exact access details, event postponements, regional releases, or organizer-specific status updates.
Why it is separate from countdown
The countdown page serves planning intent; this page serves answer intent and keeps the claim narrower so it can archive safely after the event passes.
