One memo, four vendors

Generated from the shipping adapters (hook/platforms/*.go) — not mockups. Same memo, four vendor documents, matching each platform's live hook contract (verified 2026-09-15). Regenerate deterministically: make artifact.

The memo

URGENT — PR #4821 ships today — freeze lifted 18:00 UTC The 2/14 freeze memo is superseded. The deploy window opens 18:00 UTC and closes 20:00 UTC. - Ship PR #4821 (context-freshness KPI) — it is the release gate for this window - Do NOT ship PR #4824 (still blocked on design review) - If the window slips, the new freeze memo lands before 17:45 UTC On-call: u_priya. Escalate to #incident if the window closes without a ship. [AIRMEMO · authorized · memo_4821]
