Oracle src/rune/parallel_processor.py 194 lines / 14 fns: 3/14 -> 14/14
per scripts/dichotomy_audit.py (name-preserving match). The 11
audit-named gaps land as ported Go functions in src/go/parallel-processor:
RunParallelWithArgs, GetStatus, Shutdown, ShutdownProcessor
(_shutdown_processor), GetProcessor, TestParallel (with the nested
task_1/task_2/task_3 closures) — plus the class/module run_parallel and
get_status module delegates; the CLI now mirrors the oracle main()
(status/test/usage/unknown) alongside the pre-existing run and the new
replay/op gates. Logic 1:1 with the Python oracle (semaphore-bounded
goroutine pool, submission-order results, per-task error envelopes).
Oracle quirks preserved and frozen as truth rows: submit-after-shutdown
raises from the submit loop itself (port panics 'cannot schedule new
futures after shutdown' — crash parity), ParallelProcessor(0) raises
'max_workers must be greater than 0', non-callable tasks degrade to
Python-TYPE-NAME TypeError envelopes ('int'/'NoneType'/'dict' object is
not callable), with-args parse errors carry type(task).__name__ and
repr shapes (42, 'x', True, None, [1, 2]), non-seq args wrapped to a
single-arg tuple, non-dict kwargs reset to {}, len-0 list vs () tuple
distinction, pool_threads reported as the configured bound,
active_threads pinned (rig threading.active_count patch / Go
PP_ACTIVE_THREADS seam).
Truth: scripts/gen_parallel_processor_truth.py via the shared
freeze_truth.py harness (23-case envelope; kind/fn/value SPEC grammar so
callables ride JSON rows — rig builds real Python callables, battery
rebuilds Go specCallable tasks); freeze_truth --verify byte-identical
twice; truth.json embedded VERBATIM and replayed by the go test battery
(5/5) and the binary replay gate (PARITY OK 23/23). Live parity 19/19
(scripts/check_parallel_processor_parity.py: 15 op families + 4 CLI
checks). gofmt/vet/go build clean. Python oracle smoke green both pins
(module has no loader seam; the byte-identity gate replays the live
oracle itself). Audit 3/14 PARTIAL -> 14/14 FULL.
