Review comments at @pkg/logger/writer.go:
- Around line 63-65: Update the `opaqueWriter` creation and reuse in the logger
setup and `SetOutput` paths so stderr and unchanged destinations retain a stable
wrapper identity; avoid registering a new wrapper for each call while preserving
output behavior when the destination changes.
Review comments at @pkg/process/process.go:
- Line 96: Update the command lookup around interp.LookPathDir to avoid
resolving a relative spec.Dir twice: use an absolute directory for lookup or
make the resolved command path absolute before passing it to
exec.CommandContext. Add a test covering a relative Dir and a relative PATH
entry.

Review comments at @pkg/utils/yaml_include_script_source.go:
- Line 52: Update the step-detection logic that calls mappingHasKey with
interpreterKey so it verifies the mapping is a script step by its location or
type before adding provenance fields. Keep prepareScriptSource from modifying
stack variables such as vars.bootstrap that merely contain an interpreter key.
Review comments at @pkg/utils/yaml_utils.go:
- Line 851: Update UnmarshalYAMLFromNode to expand parsed node keys using the
configured KeyDelimiter before calling decodeYAMLNode, so it matches
UnmarshalYAMLFromFile’s nested-map behavior while preserving the existing decode
flow.

what
why
Provide independently testable execution services for the Starlark runtime while fixing masking, path lookup, and terminal startup behavior for existing callers.
validation
Both logger retention and relative-path regressions failed before their fixes and now pass. Logger/process race tests passed three repetitions; full build and affected lint passed.
All touched support packages passed. Authoritative Codecov patch coverage on
75b8758is 92.56%, above the 85% target, against the actual main base.All 132 CI checks passed on
75b8758, CodeRabbit approved that exact commit, and the PR has no merge conflicts.Fix session cast tests to wait for a complete shell response rather than PTY input echo. A delayed-start regression reproduced the failure before the fix; the full step race suite and focused repeated race tests pass afterward.
The regenerated list-instances acceptance snapshot passed normal verification. The GitHub transport classifier has positive and negative regressions, and its full package tests passed.
CodeQL alert #6323 was dismissed as a confirmed, user-approved false positive: SHA-256 is used for script-content provenance, not password storage.
Updated the stack against
main(e14981b9e7) using GitHub CLI, with signed local resolutions for documentation conflicts. Current head is5a5158eff1; CI and CodeRabbit must be verified again after this update. All stack PRs are mergeable. The combined website build and nine navigation tests passed after migrating step-reference links to/steps.references
Also adds a Mergify warning for open PRs with more than 150 changed files. The comment uses the existing GitHub warning admonition style, explains the CodeRabbit review limit, and asks authors to split the change into a stack with each PR targeting its predecessor. The rule applies to all base branches.
