/home/byk/Code/opencode-v2-pilot/packages/core/src/config/normalize.ts function normalizeCompaction() rejects non-record compaction, marks legacy compaction.tail_turns and compaction.prune unsupported, decodes compaction.auto, and emits encoded.compaction when the normalized result is nonempty or the input object is empty.normalizeCompaction() maps legacy compaction.preserve_recent_tokens and native compaction.keep.tokens to compaction.keep.tokens using prefer(legacyTokens, nativeTokens, ["compaction", "keep", "tokens"], diagnostics); a present non-record compaction.keep is invalid.normalizeCompaction() maps legacy compaction.reserved and native compaction.buffer to compaction.buffer using prefer(legacyBuffer, nativeBuffer, ["compaction", "buffer"], diagnostics)./home/byk/Code/opencode-lore/packages/core/src/fetch-interceptor.ts as implementing fetch-level transparent LLM API proxy routing and exporting installFetchInterceptor.installFetchInterceptor() routes an intercepted LLM request through the Lore gateway by: 1. checking for a known LLM API path, 2. rewriting the URL while preserving the path, 3. adding X-Lore-Upstream-URL and X-Lore-Upstream-Path, 4. injecting dynamic X-Lore-* context headers from getHeaders(), and 5. preserving all original headers, including authorization and content type.Symbol.for("lore.fetchInterceptor.originalFetch") via ORIGINAL_FETCH_KEY, readOriginalFetchSlot(), and writeOriginalFetchSlot(). A non-null slot causes later installFetchInterceptor() calls to return a no-op cleanup rather than stack interceptors.Symbol.for(...) shared slot is required when multiple bundled/instantiated copies of @loreai/core exist, such as the OpenCode plugin copy and an in-process gateway bundle copy. A module-scoped handle was rejected because each copy could capture another interceptor as its “original,” creating the infinite loop gateway → interceptor → gateway → …; this cross-copy fix makes inlining core into the Bun bundle safe for issue #1027 and gateway script/bundle.ts.buildGatewayHeaders() is shared by Path 1 (URL-matched) and Path 2 (body-detected) so header handling never drifts between them.buildGatewayHeaders() supports both fetch(url, {headers}) and fetch(new Request(url, {headers})), preserves existing headers, sets x-lore-upstream-url to the resolved upstream base, and sets x-lore-upstream-path only when the original endpoint pathname begins with /.x-lore-upstream-path enables verbatim forwarding for providers whose endpoints omit /v1, specifically GitHub Copilot’s /chat/completions from issue #1052, and for providers using non-standard prefixes.config.getHeaders() are injected only when the request does not already contain the header, allowing per-request hooks to take precedence. Failures are caught and logged as fetch-interceptor: getHeaders() failed:.observeRequestHeaders() invokes optional config.onRequestHeaders(headers) and catches failures, logging fetch-interceptor: onRequestHeaders() failed:.installFetchInterceptor() captures globalThis.fetch, stores it in the shared original-fetch slot, and pre-parses config.gatewayBase into a URL once to avoid constructing a URL for every process-wide fetch./messages, /completions, or /responses; malformed URLs also pass directly to the original fetch.gatewayBase are never intercepted, but their headers are still passed to observeRequestHeaders() so in-process extensions can scope side-channel requests.upstream.hostname is exactly localhost, 127.0.0.1, 0.0.0.0, ::1, or [::1].matchesLLMApiPath(upstream.pathname), then interceptUrl(upstream, gateway). A null rewrite passes through as a safety fallback; otherwise it builds and observes gateway headers, logs fetch-interceptor: ${upstream.host}${upstream.pathname} → gateway, and calls originalFetch(rewrite.gatewayUrl, { ...init, headers }).pathLooksLLMLike(upstream.pathname) is true: it obtains the request body with extractBodyString(input, init), identifies a protocol using detectProtocolFromBody(bodyRaw), rewrites through interceptUrlForProtocol(upstream, gateway, detected), uses the shared buildGatewayHeaders(), and logs the route with (body-detected ${detected}).${upstream.host}${upstream.pathname} using warnedPaths; the warning says the endpoint matched no LLM API pattern and advises adding a pattern in fetch-interceptor.ts.globalThis.fetch = Object.assign(interceptor, originalFetch) to preserve extra properties such as newer Node.js preconnect.globalThis.fetch = originalFetch and releases the process-global slot with writeOriginalFetchSlot(null), allowing a later installation to recapture fetch./home/byk/Code/opencode-lore/packagespackages/opencode/test competing?Actually exact path/home/byk/Code/opencode-lore/packages/opencode/test{}`.
