• 🟡 (15:42) User supplied the continuation of /home/byk/Code/opencode-lore-responses-projection-security/packages/gateway/src/pipeline.ts, approximately lines 11835-12459, covering principal retry/failure projection, cleanup, incomplete-transport handling, response-header copying, truncated-body accounting, SSE body sniffing, non-stream accumulation, completion validation, and Responses output-item validation.
• 🔴 (15:42) User stated an invalid non-stream usage projection is never returned as success; invalid usage still throws, followed by throw new NonStreamCompletionError(response) around lines 12317-12322.
• 🟡 (15:42) Principal incomplete transport uses const PRINCIPAL_TRANSPORT_INCOMPLETE_REASON = "gateway_transport" around line 12070.
• 🟡 (15:42) Upstream response handling does not rely solely on the text/event-stream content type: it sniffs the body with looksLikeSSE(contentType, body) and, when SSE is detected, routes it through accumulateSSEResponse; non-SSE responses select a JSON accumulator such as accumulateOpenAINonStreamJSON.
• 🟡 (15:42) Responses completion validation can throw the exact error new Error("upstream Responses request did not complete"), including while validating response-level and output-content completion.
• 🟡 (15:42) Failed-response projection filters failedResponse.rawOutputItems, supports hidden-output handling through buildOutputItems(hiddenOutputIndices), and can emit the fallback message "Gateway request failed".
• 🟡 (15:42) User supplied /home/byk/Code/opencode-lore-responses-projection-security/packages/gateway/script/bundle.ts, including separate Node.js CJS and Bun ESM builds, worker bundles, ONNX WASM packaging, Sentry sourcemap upload/cleanup, CLI wrapper generation, and generated type declarations.
• 🔴 (15:42) User stated the Bun ESM path keeps the Node-only undici import out of the Bun bundle so real undici@7 is never bundled or evaluated under Bun.
• 🔴 (15:42) User stated the Bun path uses Bun’s fetch and never touches undici.
• 🔴 (15:42) User stated the Bun path never imports undici; the undici import is Node-only, making it safe as a devDependency only under that separation.
• 🔴 (15:42) User stated the ONNX Runtime Bun configuration uses the single-thread path and never calls its pthread new Worker(...); this is the safety condition for the pthread-spawn no-op patch.
• 🟡 (15:42) packages/gateway/script/bundle.ts generates dist/bin.cjs; the wrapper requires Node.js 22.15 or later, exits with code 1 on older versions, suggests curl -fsSL https://lore.dev/install | bash, suppresses process warning events, invokes require("./index.cjs").runCli(), and sets process.exitCode = 1 on rejection.
• 🟡 (15:42) Generated gateway declarations define GatewayConfig with port, portExplicit, hosts, upstreamAnthropic, upstreamOpenAI, idleTimeoutSeconds, and debug; defaults include port 3207, hosts ["127.0.0.1"], upstream URLs https://api.anthropic.com and https://api.openai.com, idle timeout 60 seconds, and debug false.
• 🟡 (15:42) Generated gateway declarations define StartOptions (port?, hosts?, debug?, quiet?) and GatewayHandle (config, port, owned, shutdown: () => Promise<void>).
• 🟡 (15:42) Generated declarations expose DEFAULT_PORTS as readonly [3207, 5673], DEFAULT_PORT as 3207, and functions loadConfig(), startServer(config), startGateway(opts?), probeGateway(baseURL, timeoutMs?), readPortFile(), resetPipelineState(), and _cli().
• 🟡 (15:42) The gateway bundle outputs are: dist/index.cjs (CJS, Node.js, node:sqlite), dist/index.bun.js (ESM, Bun, bun:sqlite), dist/embedding-worker.cjs (Node.js), dist/embedding-worker.js (Bun), dist/vector-worker.cjs (Node.js), dist/vector-worker.js (Bun), dist/ort-wasm-simd-threaded.{mjs,wasm} (ONNX WASM runtime), dist/bin.cjs (CLI wrapper), and dist/index.d.cts (type declarations).
• 🟡 (15:43) Search found exactly 13 applyResponsesEvent matches: in packages/gateway/src/stream/openai-responses.ts at lines 582, 1393, 1597, 1767, 2158, and 2250; and in packages/gateway/src/pipeline.ts at lines 8382, 9154, 9445, 10381, 10484, 11051, and 11127.
