Correct the service fallback documentation.
Line 10 says evlog resolves an omitted service from turn context. Line 13 passes 'eve-agent' to toHookOptions, and the option translator writes that value to init.env.service. The service is therefore fixed to 'eve-agent' when mount configuration omits service.
Update the JSDoc to describe the fixed fallback, or change the implementation to resolve the agent name as documented.

Preserve sub-percent sample rates.
sample: 0.001 is valid configuration, but Math.round() converts its intended 0.1% rate to 0%. This silently drops all routine turns for valid sub-percent settings. Pass the percentage without rounding and add a regression test.

Add a matching test for the new public tool.

As per coding guidelines, every code change must have a matching test, and bug fixes require a failing regression test before the fix.

Prevent annotation keys from overwriting evlog-owned fields.
set() merges into the logger context with Reflect.set, and emit() exposes that context to tail sampling and drains. Values accepted for this tool can overwrite evlog-owned fields such as service, error, approval, audit, and request_id; use a dedicated namespace/prefix for annotations or reject reserved top-level keys.

Enforce annotation value eligibility before storage.
The annotation schema permits any primitive value, but the extension only documents what agents must not write. With redact: false or { paths } that does not include the dynamic annotation key, raw values can drift into the drain pipeline at least via built-in pattern matches. Add deterministic validation at this boundary, such as allowing only business identifiers and amounts, and add tests for the tool schema and policy.

Assert adapter delivery and batching behavior.
This test only checks that drain() resolves. It does not prove that the memory adapter received the event after OTLP fails. It also leaves the batching branch untested. Use controlled drain spies and fake timers to assert fan-out, failure isolation, and batch payload delivery.
As per coding guidelines, “Every code change must have a matching test” and tests must use helpers from test/helpers/.
