initConsoleProviders sets up stdout exporters for traces and metrics.

initRepoWithNonASCIIChange creates a repository whose changed file path contains both non-ASCII characters and Next.js-style route groups. It forces G

injectDiffMap builds a read-only DiffMap from parsed diffs and sets it on the FileReadDiffProvider. Must be called after loadDiffs and before any conc

injectScanContentMap fills the file_read_diff tool's DiffMap with full file content keyed by path, so if the model calls it the tool returns the whole

isLoopbackHost reports whether host is a loopback name or IP literal that is always safe to accept regardless of operator configuration.

listFiles returns all source files under repoDir. In a git repo it uses `git ls-files` for full .gitignore semantics (nested + global excludes + negat

newStdoutMetricExporter creates a console metric exporter with pretty-print output.

newStdoutTraceExporter creates a console trace exporter with pretty-print output.

otlpSignalURL builds the URL for one signal from the configured endpoint. OTEL_EXPORTER_OTLP_ENDPOINT is defined by the OpenTelemetry specification a

parseBatchStrategy normalizes a user-supplied strategy string. Unknown or empty values fall back to BatchNone (safe v1 behavior).

parseFilterResponse extracts comment indices from the LLM filter response. Returns a set of 0-based indices. Invalid IDs or out-of-range indices are i

parseOTLPEndpoint strips a http:// or https:// scheme from the endpoint and reports whether the connection should be plaintext (insecure). Scheme matc

parseTimeoutEnv reads and validates the OCR_LLM_TIMEOUT environment variable. Returns the parsed duration and true if set, or 0 and false if unset/emp

printDiffLine renders a single diff line with colored prefix and background on content.
