Modules§
- arena
- arrow_
ingest - csr_
edges - debug_
views - delta_
edges - effects
- Formal effects pipeline for evaluation (ticket 603).
- eval
- eval_
delta - graph
- ingest

builder - interval_
tree - journal
- Internal action journal types used for atomicity and undo/redo.

registry - spill
- Spill interfaces (shim) for reserve/write/commit/rollback lifecycle. Phase 2: Introduce types only; implementation can delegate to current graph methods.

- tuning
- Warmup configuration and tuning parameters
- vertex

store - virtual_
deps
Structs§
- Eval
Config - Configuration for the evaluation engine
- Formula
Parse Diagnostic - Captured diagnostic for a malformed formula encountered during ingest/graph-build.
- Spill
Config - Configuration for spill behavior. Nested under EvalConfig to avoid bloating the top-level.
Enums§
- Date
System - Deterministic
Mode - Deterministic evaluation configuration.
- Formula
Parse Policy - Policy for handling malformed formulas encountered during workbook ingest.
