acativa

Multi-Agent Collaboration Strategy Compiler — a generic runtime, state machine and durable strategy store for centralized and decentralized multi-agent collaboration.

acativa is host-agnostic. It compiles a workflow definition into a checked plan, reduces run events into deterministic snapshots, persists runs, commands and delivery intent in a durable SQLite store, and executes effects through host-owned adapters and ports. It carries no product schema, package format or host-vocabulary dependency: a host binds its own schema identity, persisted vocabulary and effect implementations at every admission boundary.

Layout

• workflow — definition IR, syntax-independent validation, diagnostic codes, the schema-parameterized compiler, the deterministic run machine and pure dispatch planning.
• store — the durable strategy store: admission, routing, controlled state, queues, subscriptions, commit decoration and dispatch composition over SQLite.
• runtime — capability adapters, node facades, the continuous node driver, host effect ports and evolution seams.
• util — host-agnostic support: private-path hardening, atomic writes, bounded archive extraction, SQLite schema-contract comparison and display naming.

Identity model

A host names the workflow schema it accepts with SchemaId and hands it to compile_workflow / compile_workflow_source. Compiled plans carry a PlanKey — the definition revision plus the compiler semantics, engine semantics and lowering capability identities — so a retained plan is always verified against the exact identity it was lowered under, and an old run is either re-admitted or handed off, never silently re-lowered.
