Fields

checkpoint_id: Option<String>

Durable checkpoint installed by this compaction, when applicable.

strategy_used: String

Combined strategy description (e.g., “observation_masking+native”).

messages_before: usize

Number of messages before compaction.

messages_after: usize

Number of messages after compaction.

tokens_before: Option<u64>

Estimated or provider-reported input tokens before compaction.

tokens_after: Option<u64>

Provider-reported output tokens after compaction, when available.

bytes_before: Option<u64>

Serialized request-context bytes before compaction, when measurable.

bytes_after: Option<u64>

Serialized compact output bytes, when measurable.

duration_ms: u64

Total duration of all compaction steps in milliseconds.

steps: Vec<CompactionStepData>

Individual steps in the cascade.

trigger: CompactionTrigger

What triggered this compaction: context-window budget or cost pressure.

model: String

Model that performed the compaction.

provider: Option<String>

Provider backend (e.g. “openai”), when known.

driver: Option<String>

Local driver identifier, when known.

budget_remaining_tokens: Option<u64>

Tokens of headroom remaining when the install completed, when measurable.

source_sequence: Option<i64>

Source message sequence the compaction ran at, when known.

cache_read_tokens: Option<u32>

Cached input tokens read after compaction, when reported.

cache_creation_tokens: Option<u32>

Cache-creation tokens written after compaction, when reported.
