Enum CompactionReason 

pub enum CompactionReason {
    Summarized,
    Truncated,
}

Why a turn’s prompt was auto-compacted before it ran. The buffered analog of WireCompactionReason, lifted to a closed Rust enum so surfaces match on it without touching the wire crate.

Variants

Summarized

Older turns were folded into an anchored-iterative summary (message-count trigger). The summary survives as the prompt’s preamble.

Truncated

Older tool-output payloads were trimmed to fit the token budget (char/token-budget trigger). No messages were dropped, only their bulk.

NOTE: the control plane no longer EMITS this reason — the retroactive tool-output truncation layer was removed in favor of token-budget summarization (the per-call tool-output cap now bounds individual tool results). This variant is retained as a never-emitted-on-happy-path decode path so any old persisted/wire value still maps (the enum stays exhaustive) and an unknown future wire reason has a quiet fallback.

Implementations

impl CompactionReason

pub fn notice_headline(self, summarized_messages: u32) -> String

Canonical one-line headline (with a leading glyph) for a pre-turn compaction notice, shared by every edge so the user-facing wording can’t drift between Slack, Telegram, and the rest. summarized_messages is used only by Self::Summarized. Returns PLAIN text — no markup — so each surface applies its own emphasis/escaping (Slack _…_ mrkdwn, Telegram *…*, …) without double-formatting.
