/home/byk/Code/opencode-lore/packages/core/src/fetch-interceptor.ts, type Rewrite has 3 string fields: gatewayUrl, upstreamBase, and upstreamPath. upstreamPath preserves the client’s full original endpoint pathname for forwarding as x-lore-upstream-path, including endpoints omitting /v1 such as GitHub Copilot’s /chat/completions (issue #1052) and endpoints with non-standard prefixes.interceptUrl(upstream: URL, gateway: URL): Rewrite | null first finds the last "/v1/" in upstream.pathname; on success it sets gatewayUrl to gateway.origin + pathname-from-/v1/ + upstream.search, upstreamBase to the upstream origin plus the path prefix before /v1/, and upstreamPath to the complete original pathname."/v1/" exists, interceptUrl() iterates Object.entries(NON_STANDARD_PATH_REWRITES) and rewrites a matching pathname suffix to its canonical gateway path while deriving upstreamBase by removing that suffix; the documented example is /codex/responses → /v1/codex/responses. It returns null if neither strategy maps the URL.interceptUrlForProtocol(upstream: URL, gateway: URL, protocol: BodyProtocol): Rewrite is Path 2 for body-detected protocols and is used only after interceptUrl cannot map a genuinely non-standard URL such as /v2/chat/completions or /llm/messages. It selects the canonical gateway endpoint via PROTOCOL_GATEWAY_PATHS[protocol].interceptUrlForProtocol(), upstreamBase initially equals upstream.origin; the function iterates LLM_ENDPOINT_SUFFIXES, and when upstream.pathname.endsWith(suffix), derives the provider base by stripping that endpoint suffix from the pathname. If no recognized suffix exists, it retains the origin fallback.
