=== Appendix N: Per-file / submodule implementation plan (build + tests in turn) ===

Implement each submodule with its own harness before proceeding:
# types.py — public contract.
# util.py — ring buffer, time helpers.
# prompting.py — build_message_stack() (pure-ish) + tests.
# loopdetect.py — repeated-line detector + tests.
# process.py — process group start/stop + log capture + no-orphans tests.
# transport.py — readiness probe + SSE streaming parser + stub server fixture + tests.
# liveness.py — /proc/<pid>/stat CPU ticks + tests.
# timeouts.py — pure timeout/crash-loop evaluation + tests.
# exit_signals.py — record exit tool calls + tests.
# tooling.py — tool-loop (iteration budget) + fallback parsing + failure classification + tests.
# worker.py — orchestration glue + unit-ish tests (mock components).
# Full integration tests against the stub server.

This design is intentionally strict about invariants (slots, restart semantics, output retention, tool iterations) to keep implementation straightforward and robust in a multi-worker environment.
