Module state 

Borrow-lens view types used by crate::service::ContextService.

Each view holds &/&mut references to the exact sub-fields that the context service needs. By accepting lenses instead of &mut Agent<C>, this crate avoids depending on zeph-core while still letting the call site in zeph-core construct them from disjoint field projections.

Views are constructed at the call site in zeph-core using one literal struct expression. The borrow checker proves disjointness at that level without additional helper methods — each &mut resolves to a unique field path under Agent<C>.

Structs

ContextAssemblyView

Borrow-lens over all fields needed for prepare_context and Agent<C>::rebuild_system_prompt.

ContextDelta

Values produced by crate::service::ContextService::prepare_context that must be applied by the caller.

ContextSummarizationView

Borrow-lens over all fields needed for compaction and summarization operations.

MessageWindowView

Borrow-lens over the agent’s conversation window fields.

MetricsCounters

Accumulated metric deltas for one context-assembly pass.

ProviderHandles

Bundle of LLM provider handles needed for async context operations.

Enums

CompactionOutcome

Return type from compact_context() that distinguishes between successful compaction, probe rejection, and no-op.

ProbeOutcome

Verdict returned by a CompactionProbeCallback after evaluating a candidate summary.

Traits

CompactionPersistence

Persistence completion hook invoked after the in-memory drain/reinsert is finalized.

CompactionProbeCallback

Probe-validation callback invoked by ContextService::compact_context after the LLM produces a candidate summary.

MetricsCallback

Metrics-counter sink for ContextService increments.

SecurityEventSink

Abstract sink for security events raised during context assembly.

StatusSink

Abstract status sink for emitting short progress strings to the channel.

ToolOutputArchive

Pre-summary tool-output archiving hook (Memex #2432).

TrustGate

Abstract gate for applying a skill trust level to the tool executor.

Type Aliases

QdrantPersistFuture

Boxed 'static future for the off-thread Qdrant session-summary write.
