Modules

auto

Unified automatic compaction orchestration.

memory_envelope

Session memory envelope + local compaction helpers, shared by every compaction path (auto, manual /compact, model-switch, recovery, fork).

prefire

two_pass

Pure builders for prefire two-pass compaction.

Structs

CompactionConfig

Compaction configuration for context window management.

CompactionParentContext

Parent request prefix for cache-safe compaction forking.

CompactionRoutePolicy

Per-route compaction policy in the DeepSeek-harness shape.

ManualCompactionOptions

Universally meaningful manual-compaction options.

Enums

CompactionStrategy

How the manual /compact command compacts for a given provider/model.

Constants

SUPPRESS_NONE

SUPPRESS_STICKY

SUPPRESS_TURN

SUPPRESS_UNTIL_SUCCESS

Functions

bound_compacted_history_to_context

Bound a locally managed compacted history to the resolved context budget, including any caller-supplied session ceiling. Standalone native responses must bypass this helper: their retained items and opaque continuation state are the provider’s canonical next context window.

build_cache_safe_compaction_history

Build a cache-safe compaction history: the parent’s full conversation prefix verbatim, plus the compaction instruction as the only new turn. From the provider’s perspective this looks nearly identical to the parent’s last request, so the cached prefix is reused.

compact_history

Compact conversation history using the configured summarizer.

compact_history_manual

Compact history for the manual /compact command using provider-native compaction when available, falling back to local summarization otherwise.

compact_history_manual_with_budget

Manual compaction with the resolved session context budget applied to native request inputs and locally rebuilt summaries. Native provider responses are returned unchanged so opaque continuation state remains valid.

compact_history_manual_with_parent_context

Manual compaction that reuses the parent segment’s cached prefix.

compact_history_with_budget

Compact conversation history using a caller-resolved context budget for input bounding and locally rebuilt output. Standalone native responses are returned as the provider’s canonical next context window.

compacted_history_shrinks

Whether a compaction result is worth keeping.

manual_compaction_strategy

Select the manual-compaction strategy for a provider/model.
