Struct EnvelopeMeta 

pub struct EnvelopeMeta {
    pub announced_at: u64,
    pub ttl_secs: Option<u32>,
    pub flags: u8,
}

Per-envelope metadata grouped to keep the sign / placeholder constructor signatures narrow. All three fields are wire-envelope members; defaults match the most common publisher pattern (current wall-clock micros, default TTL via FoldKind::DEFAULT_TTL, no flag bits set).

Fields

announced_at: u64

Publisher’s wall-clock micros-since-epoch at emission. Receivers use this for diagnostics, not for ordering — generation is the load-bearing anti-reorder signal.

ttl_secs: Option<u32>

Per-announcement TTL override. None falls through to super::FoldKind::DEFAULT_TTL.

flags: u8

Bit flags. See SignedAnnouncement::flags for the reserved layout.
