Answer lifecycle

How this DID page changes over time

Before the date

Answer remains no

Upcoming records point users to /countdown/openai-devday-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 OpenAI DevDay 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 openai.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.
