validate

Ensures string literal keys used in translation calls exist in the source locale JSON. Calls whose first argument is not a static string are reported as dynamic (heuristic scan via packages/cli/src/core/extractor/dynamic/ — same rules as sync warnings).

Literal key set: built from per-file key-site scanning so `${NS}.segment` uses each file’s own const map (duplicate NS in different files does not collide). See Duplicate const identifiers.

Limits: extraction is regex/heuristic, not a full TypeScript semantic analysis. See Detection limits and translation call extraction (known gaps and indirection).

i18nprune validate
i18nprune validate --json

Uses config functions, src, and resolved source path. See CLI overview and verbosity.

validate --json: data.count matches data.keyObservations.count (literal key observations scanned). Keys in code missing from the source locale JSON are data.missing — use missing.length for that total, not data.count.
