Architectural review of the refactorer's postHeights index work. Extract a shared assemblePostPage helper and a ListUseCase base class to remove DRY duplication in the post-list use cases. Build the gherkin-mutator runner adapter for psf-memo-db and psf-memo-indexer. Add boundary and tie-break tests to kill all surviving language mutations across the changed files (post-query, pagination, list use cases, indexer post handler). Mutation: all changed source files fully killed. DRY: clean. CRAP <= 6. Soft Gherkin acceptance mutation documented survivors (see review report). By architect.

/*
|
|
Persistent runner adapter for the APS gherkin-mutator (psf-memo-db).
|
|
|
|
The mutator starts this process (once per worker) and sends mutation jobs
|
|
over newline-delimited JSON on stdin. Each job carries the path to a mutated
|
|
feature JSON IR; this worker evaluates it through the same acceptance runtime
|
|
and step handlers used by the normal acceptance pipeline and replies with the
|
|
runner outcome.
|
|
|
|
Protocol (mutator-spec.md):
|
|
request: { "id", "feature_json", "generated_dir", "work_dir" }
|
|
response: { "id", "outcome", "output", "error", "duration" }
|
|
outcome: test_success | test_failure | infrastructure_error
|
|
|
|
test_failure (acceptance failed) -> mutation killed
|
|
test_success (acceptance passed) -> mutation survived
|
|
|
|
stdout is reserved for JSON responses. The db libraries (config, adapters)
|
|
log to stdout via console.log, so that logging is redirected to stderr below;
|
|
otherwise the mutator would read non-JSON lines as worker responses.
