Silences

Ad-hoc "don't notify about this for N minutes". Unlike maintenance windows, these are one-off.

Creation

• rule_id — optional, restricts to a rule
• label_matchers — {host: "web-01", env: "prod"} — an exact match
• expires_at — required, max 30 days
• comment — for later tracking

Extension

PATCH /silences/{id} with extend_seconds or new_expires_at. The total TTL is still at most 30 days from creation.
