Module session 

Session-based Lua execution with pause/resume on alc.llm() calls.

Runtime layer: ties Domain (ExecutionState) and Metrics (ExecutionMetrics) together with channel-based Lua pause/resume machinery.

Structs

ExecutionResult

Session completion data: terminal state + metrics.

PendingFilter

Per-field filter controlling which LlmQuery attributes are projected into a Snapshot’s pending array.

Session

A Lua execution session with domain state tracking.

SessionRegistry

Manages active sessions.

Enums

FeedResult

Result of a session interaction (start or feed).

PromptProjection

Prompt projection mode — 3 states rather than a bool so that truncation length can travel inside the filter object.

SessionError

Constants

DEFAULT_PROMPT_PREVIEW_CHARS

Default preview length (chars) used when PendingFilter::preset_preview() is constructed without an explicit length. Env var ALC_PROMPT_PREVIEW_CHARS (resolved in AppConfig) overrides this.
