Persist passed recursive tasks incrementally in a versioned journal under the workspace's node_modules directory. Hash the invocation's task graph, script commands, arguments, environment, and execution settings so only compatible state is reused.
Use unique per-run journals, cross-process serialization around the atomically published latest-run pointer, open file handles, and newline-committed records to reject stale, superseded, malformed, torn, or unsafe state. Remove each journal after its invocation succeeds and preserve the existing dependency-pruning fallback when no compatible state is available.
Implement the same state format and resume semantics in the TypeScript CLI and Rust pnpm port, with shared identity fixtures guarding cross-implementation compatibility.
