Skip factory-state and allocator by default with explicit skip messages. Preserve both scenarios and enable them with NSL_TEST_RUNTIME_ALLOCATOR=1. Document the deferred runtime issue and remaining validation limits.
Validation: nimble test passes 32 unit tests, 29 regression tests, and 11 sanitizer scenarios, with two skips. Opt-in execution still reports both known allocator failures.
Serialize writer submission and shutdown, enqueue explicit stop messages after accepted records, and finish the final file batch before joining. Keep drained process-wide channel storage until exit to avoid the Nim 2.2.10 Channel.close mutex teardown defect.
Cover empty records, multiple destinations, joined producers, and concurrent shutdown. Include writer lifecycle sanitizer tests in nimble test and update usage documentation.
Validation: all 32 unit tests, eight writer exit scenarios, and writer lifecycle ThreadSanitizer tests pass. The full suite retains the known configuration refresh, timestamp, and default allocator failures.
Add SharedLogState for synchronized value data and factories for
independently owned appender state and captured formatter closures.
Reject unsafe configuration state, update the test collector to value
snapshots, and document the breaking APIs in version 3.0.0.
Expand ORC ownership and sanitizer coverage and reject stale test
executables.
