dr-exec

Contract-driven local process execution.

Status

The complete v1 surface is implemented:

  • identity and serialization — canonical secret-safe projections, the strict bounded read path, and role-specific versioned identities;
  • the isolated-host Python runtime with its fixed -I probe and the library-owned child wrapper;
  • the protected protocol — request transport, frame codec, the prelude/output/completion state machine, and finite executor self-budgets;
  • durable recording — DirectoryRunStore over the pinned Document Directory, with typed lifecycle handles, receipts, and strict load validation;
  • the single-run engine behind ProcessExecutor.run — spawn through teardown for trusted-command, untrusted-command, and untrusted-Python targets, with budget enforcement, best-effort attribution, and the mandatory record lifecycle;
  • FakeExecutor, which enforces the same declaration rules and carries an explicit fake receipt, plus the shared behavioral conformance suite both executors pass;
  • the bounded execution pool — one scheduler core behind ProcessExecutor.run_many, ProcessExecutor.open_pool, and ExecutionPool.run_stream, with one shared resident bound over running and completed-but-undelivered submissions, completion-order delivery, backpressure on intake, cancellation, drain, and abort.

Execution runs on macOS; the engine refuses other platforms at the declaration boundary, and the tests that need real process semantics are marked accordingly.
