Distillation

🔴 (13:20) User provided repository instructions at /home/byk/Code/opencode-lore-v2/AGENTS.md. 🔴 (13:21) User showed the active Jujutsu working-copy change as change ID wlpqmtosolpk, commit 35358505e1c3, description feat(opencode): add V2 server plugin; its parent is change ID uutomtupslqm, commit 429114122aa1, main | fix(gateway): preserve large recall continuations (#1730). 🔴 (13:22) User showed 14 working-copy paths: modified packages/core/src/fetch-interceptor.ts, modified packages/core/src/index.ts, added packages/core/test/fetch-interceptor-request.test.ts, modified packages/opencode/package.json, added packages/opencode/script/build.ts, modified packages/opencode/src/index.ts, modified packages/opencode/src/internal.ts, added packages/opencode/src/server-runtime.ts, added packages/opencode/src/server.ts, modified packages/opencode/test/internal.test.ts, added packages/opencode/test/package.test.ts, added packages/opencode/test/server-runtime.test.ts, added packages/opencode/test/server.test.ts, and modified pnpm-lock.yaml. 🔴 (13:22) User stated requests already going to the gateway must never be intercepted and should always pass through; their headers may still be observed for in-process extension authentication and side-channel scoping. 🔴 (13:22) User stated local requests must never be intercepted because they could target a local LLM or the gateway itself, and local hosts must never be routed through the gateway. 🔴 (13:22) User defined local hosts in packages/core/src/fetch-interceptor.ts through isLocalHost(host) as localhost, 127.0.0.1, 0.0.0.0, ::1, and [::1]; both bracketed and unbracketed IPv6 loopback forms are accepted because Node’s URL.hostname keeps brackets. 🔴 (13:22) User stated the new rewriteRequest() primitive never reads the request body: known LLM paths can safely carry streaming bodies, while unknown paths always pass through unchanged. 🔴 (13:22) User added exported types DynamicRequestHeaders = Readonly<Record<string, string>> and DynamicRequestHeadersSource = DynamicRequestHeaders | (() => DynamicRequestHeaders) in packages/core/src/fetch-interceptor.ts. 🔴 (13:22) User added public async function rewriteRequest(request: Request, gatewayBase: string, dynamicHeaders: DynamicRequestHeadersSource, onRequestHeaders?: (headers: Headers) => void): Promise<Request> in packages/core/src/fetch-interceptor.ts, implemented through rewriteRequestForProtocol(). 🔴 (13:22) User exported rewriteRequest, DynamicRequestHeaders, and DynamicRequestHeadersSource from packages/core/src/index.ts alongside installFetchInterceptor, shouldIntercept, and FetchInterceptorConfig. 🔴 (13:22) User added mayBeLLMRequest(url) in packages/core/src/fetch-interceptor.ts; it recognizes URLs containing /messages, /completions, or /responses and provides the fast exit before URL parsing. 🔴 (13:22) User implemented rewriteRequestForProtocol() so non-LLM requests return the original Request; direct-gateway requests return the same object after observeRequestHeaders(); local requests return unchanged; known paths use interceptUrl(); body-detected protocols use interceptUrlForProtocol(); and unmatched requests return unchanged. 🔴 (13:22) User refactored gateway header construction from buildGatewayHeaders(input, init, upstreamBase, upstreamPath, config): Headers to mutating helper applyGatewayHeaders(headers, upstreamBase, upstreamPath, dynamicHeaders): void; dynamic headers may be a record or callback, existing request headers take precedence, and callback failures are logged as fetch-interceptor: getHeaders() failed:. 🔴 (13:22) User changed observeRequestHeaders() to accept the optional callback directly rather than all of FetchInterceptorConfig; callback failures remain logged as fetch-interceptor: onRequestHeaders() failed:. 🔴 (13:22) User refactored installFetchInterceptor() to share routing behavior with rewriteRequestForProtocol(), while retaining body-based protocol detection only for LLM-looking unknown paths where extractBodyString(input, init) is available. 🔴 (13:22) User preserved warning-once behavior for unknown LLM-looking paths using key ${upstream.host}${upstream.pathname} and message fetch-interceptor: ${upstream.host}${upstream.pathname} matched no LLM API pattern — request bypassing Lore gateway. Add a pattern in fetch-interceptor.ts if this is an LLM endpoint. 🔴 (13:22) User changed installed-interceptor request handling so an existing Request with no init is reused; otherwise it creates new Request(input, init). If routing returns the same request, it calls originalFetch(input, init); routed Request inputs call originalFetch(routed), while other inputs call originalFetch(routed.url, { ...init, headers: routed.headers }). 🔴 (13:22) User added 7 regression scenarios in packages/core/test/fetch-interceptor-request.test.ts: 1. a V2-style OpenRouter request preserves POST method, JSON body, authorization, x-api-key, path, query, dynamic context headers, and observed routed headers while rewriting https://openrouter.ai/api/v1/chat/completions?stream=true&trace=abc to https://gateway.example.com/v1/chat/completions?stream=true&trace=abc, with x-lore-upstream-url=https://openrouter.ai/api and x-lore-upstream-path=/api/v1/chat/completions; 2. caller-provided x-lore-session-id=request-session overrides dynamic value session-123; 3. a direct gateway request remains object-identical, receives no dynamic project header, and its original headers are observed; 4. requests to localhost, 127.0.0.1, 0.0.0.0, and [::1] remain object-identical; 5. https://registry.npmjs.org/package remains unchanged; 6. a ReadableStream<Uint8Array> body on https://api.anthropic.com/v1/messages routes to /v1/messages without consuming the original body; 7. a streaming JSON body on unknown path https://api.example.com/v2/chat/completions?stream=true is neither read nor routed and remains readable afterward. 🔴 (13:22) User configured the streaming-request tests with duplex: "half" and @ts-expect-error because Node fetch requires duplex for stream bodies. 🔴 (13:22) User added the @loreai/opencode/server package export in packages/opencode/package.json, mapping types to ./dist/server.d.ts and both bun and default to ./dist/server.js. 🔴 (13:22) User replaced the @loreai/opencode no-op build script echo '@loreai/opencode ships raw TS — no build step needed' with tsx script/build.ts. 🔴 (13:22) User added optional peer dependency @opencode/plugin >=0.0.0, development dependency @opencode/plugin 0.0.0-beta-19378, retained @opencode-ai/plugin >=1.1.0, and added dist/ to published files in packages/opencode/package.json. 🔴 (13:22) User added packages/opencode/script/build.ts; it deletes and recreates packages/opencode/dist, bundles src/server.ts to dist/server.js with esbuild using ESM, Node platform, target: "esnext", source maps, and externals @opencode/plugin, @loreai/core, and @loreai/gateway, then invokes TypeScript via process.execPath and require.resolve("typescript/bin/tsc") to emit declarations only into dist with --skipLibCheck, --target ESNext, --module ESNext, --moduleResolution bundler, and src/ as --rootDir. 🔴 (13:22) User extracted parseUpstreamExtraHeaders(value) into packages/opencode/src/internal.ts; it returns Array<[string, string]>, splits on \n, uses the first : as separator, trims names and values, and ignores missing values and lines whose separator is absent or at index 0. 🔴 (13:22) User changed packages/opencode/src/index.ts to use parseUpstreamExtraHeaders(process.env.LORE_UPSTREAM_EXTRA_HEADERS) and forward only names accepted by shouldForwardUpstreamExtraHeader(name), preserving gateway-managed headers. 🔴 (13:22) User added packages/opencode/src/server-runtime.ts with LoreServerRuntime, ServerRuntimeDependencies, GatewayHandle, and ref-counted GatewayLease; runtime data includes gatewayBase, projectPath, gitRemote, gatewayHeaders, and async release(). 🔴 (13:22) User defined gateway discovery order in resolveGatewayUrl(): 1. normalized LORE_REMOTE_URL, falling through with an informational log if unreachable; 2. normalized LORE_GATEWAY_URL; 3. a port from @loreai/gateway’s readPortFile() when available; 4. known loopback ports 3207 and 5673; every candidate is verified with probeGateway(). 🔴 (13:22) User implemented fallback gateway startup in createGatewayLease(): dynamically import @loreai/gateway, log No Lore gateway found, starting in-process…, call startGateway({ quiet: true, local: true }), and use http://127.0.0.1:${handle.port}; shutdown is retained only when handle.owned is true. 🔴 (13:22) User implemented shared gateway leasing through module-level gatewayLeasePromise; acquireGatewayLease() increments refs, waits and retries if the lease is closing, clears failed promises, and releaseGatewayLease() shuts down only after the final reference is released and then clears the active promise. 🔴 (13:22) User made LoreServerRuntime.release() idempotent with a released flag and ensured a failure while resolving getGitRemote(projectPath) releases the gateway lease before rethrowing. 🔴 (13:22) User added test-only resetServerRuntimeForTest(), which throws Server runtime reset is test-only unless NODE_ENV === "test", clears gatewayLeasePromise, awaits the prior lease, and invokes its optional shutdown. 🔴 (13:22) User configured acquireServerRuntime() to return undefined in tests or when an argument contains .test., unless LORE_OPENCODE_FORCE_ACTIVE === "1"; it also returns undefined when LORE_DISABLED is exactly "1" or "true". 🔴 (13:22) User added buildServerHeaders() in packages/opencode/src/server-runtime.ts; it builds gateway access headers plus x-lore-session-id, x-lore-agent, x-lore-project, x-lore-git-remote, and x-lore-provider, optionally adds x-parent-session-id, reads provider-specific upstream URL from LORE_UPSTREAM_${providerID.toUpperCase().replace(/-/g, "_")}, and forwards allowed values from LORE_UPSTREAM_EXTRA_HEADERS. 🔴 (13:22) User added the OpenCode V2 server plugin at packages/opencode/src/server.ts, exported as a default object satisfying Plugin.Plugin with id: "lore" and async setup(ctx). 🔴 (13:22) User defined 3 hidden subagent workers in exact order in packages/opencode/src/server.ts: 1. lore-distill — Lore memory distillation worker; 2. lore-curator — Lore knowledge curator worker; 3. lore-query-expand — Lore query expansion worker. Each is set to mode = "subagent" and hidden = true through ctx.agent.transform(). 🔴 (13:22) User implemented the V2 model.request hook to retrieve the session by event.sessionID, tolerate lookup failure with .catch(() => undefined), build context headers from session, parent, agent, provider, project, Git remote, and gateway data, merge them into event.headers, and set event.baseURL = ${runtime.gatewayBase}/v1 when x-lore-upstream-url exists. 🔴 (13:22) User implemented the V2 http.request hook to replace event.request with await rewriteRequest(event.request, runtime.gatewayBase, {}). 🔴 (13:22) User implemented plugin setup rollback with Promise.allSettled() over all completed registration disposals plus runtime.release() before rethrowing setup errors. 🔴 (13:22) User implemented idempotent plugin cleanup with a cleaned flag; cleanup disposes every registration and releases the runtime concurrently via Promise.allSettled(), collects all rejected reasons, and throws new AggregateError(failures, "Lore plugin cleanup failed") when any cleanup operation fails.
