process.env. You'll be asked to provide them before it can run.CACHE_PATH— unset Override the content cache file path. Must include a filename (not just a directory). Does not move the index cache.CACHE_TTL_MS— 86400000 Content cache freshness window in milliseconds. Integer >=0. 0 means the cache is never considered fresh (fetch each load); values > 1 year are capped.DOCS_CACHE_MAX_STALE_MS— 0 Maximum allowed age for stale cache fallback. Validated on startup; must be an integer >=0. 0 disables the limit.FETCH_TIMEOUT_MS— 30000 HTTP fetch timeout in milliseconds. Integer >=0. 0 results in immediate timeout.MAX_INDEX_CACHE_BYTES— 52428800 Max serialized index size in bytes before writing cache. Validated on startup; must be an integer >0. If exceeded, index cache write is skipped (server keeps in-memory index).MAX_RESPONSE_BYTES— 10485760 Max HTTP response size in bytes. Integer >0. If declared or streamed size exceeds, fetch fails and falls back to stale cache when available.XDG_CACHE_HOME— unset Base cache directory for defaults.
