Python-based modules can collect coverage data when coverage is enabled.
Module discovery supports package-based keys, and Python module directories now use shorter names.
Documentation
Migration notes explain the Python module directory change and its deployment impact. Existing deployment paths and PYO3_PYTHONPATH values using the old directory names need updating or regeneration.
Chores
Local files with any extension and registry files are now excluded from relevant packaging and scanning workflows.
No actionable comments were generated in the recent review.
Walkthrough
The PyO3 runner adds optional coverage measurement around Python hooks. The CLI and generated deployments adopt updated PyO3 module directory names. Runner tests and example modules are updated. Ignore rules are broadened, and two JavaScript tool lockfiles are refreshed.
Adds coverage.py 7.15.0 and a feature-gated ET_TEST_COVERAGE setting. The runner starts coverage with its resolved Python path when the setting is enabled. Coverage configuration includes PyO3 runner data in the combined report.
Coverage measurement in hooks services/ws-pyo3-runner/src/coverage.rs, services/ws-pyo3-runner/src/python.rs, services/ws-pyo3-runner/src/agent.rs
Adds coverage setup, per-hook tracing and saving, and a background save loop. Hook dispatch uses the coverage wrapper when the feature is enabled. Runner teardown saves coverage data after the Python worker exits.
The CLI derives runtime keys from declared package names for selected module roots and retains directory-name keys for other roots. PyO3 modules move to directories without the repeated pyo3- prefix. Documentation, tool configuration, and test references use the updated paths.
Runner tests and module state services/ws-pyo3-runner/tests/*, modules/pyo3/*
Runner tests pass explicit module directories, add binary echo and initial-empty-storage checks, and wait for graceful process exit. Example modules store runtime state in dictionaries.
Root and generated Docker ignore rules exclude registry.yaml and broaden local-file exclusions from .local.md to .local.*. The server-specific ignore file is removed. Gitleaks and lychee use broader local-file patterns.

The change is mergeable with owner awareness: coverage-enabled runs can lose a hook result after a coverage failure, and ignored local YAML files can still fail the filename check.

Hook outcome is lost if trace_current_thread or save fails.
trace_current_thread(py)? returns before the hook runs. If it fails, the hook is skipped. save(py)? also runs before outcome is returned. If saving fails, a successful hook result is discarded. A failed hook error is also replaced by the save error. This matters most for on_shutdown and for on_text_frame replies. A coverage problem then changes runner behavior, although coverage is only a test aid.
Log tracer and save failures, then return outcome.

Consider splitting start to reduce complexity.
Codacy reports a cyclomatic complexity of 14 for start, above the limit of 10. Path building, suffix creation, and the Python setup are separate steps. Extract the Python setup into a named helper. Add #[expect(clippy::single_call_fn, reason = "...")] with a real reason, as the repository guidelines require.

Keep local files out of ls-lint-check.
If a developer creates notes.local.yaml, Git ignores the file, but ls-lint-check still scans it. The filename does not satisfy the configured YAML naming rule, so the local check fails. Add a matching exclusion to config/ls-lint.yaml. As per coding guidelines, “When you add a path to .gitignore, update their ignore lists too,” including ls-lint’s ignore. (raw.githubusercontent.com)
