Each module now runs in a real Deno Worker with per-module permission
sandboxing. The I/O bridge relays Worker postMessage calls through the
parent to CoreService gRPC, so modules can access store, files, and
processes without direct network/filesystem access.
- Worker bootstrap (worker-entry.ts): sets up RPC bridge, dynamically
imports module, calls init(core) with typed I/O object
- ModuleRegistry rewritten: creates Workers with Deno permission
constructor, handles LOADING → RUNNING → STOPPED lifecycle
- Structured ModulePermissions (read/write/net/run) replaces flat
string array in Go→Deno JSON-RPC
- I/O bridge: Worker postMessage → parent dispatchRPC → CoreClient
gRPC → response relayed back to Worker
- Test module proves end-to-end: Worker calls core.storeSet() →
Go verifies value in store
40 unit tests + 3 integration tests (Tier 1 boot + Tier 2 bidir + Tier 3 Worker).
