esbuild bundles the lean pi-SDK graph (the 13 exports loadPiSdkRuntime needs) into a single IIFE, dist/pi-sdk-snapshot.js, that publishes globalThis.__PI_SDK_RUNTIME__. - src/snapshot-entry.ts: imports the SDK exports, assigns the runtime global. - scripts/build-snapshot-bundle.mjs: format:iife, platform:node (node builtins external), deep-import plugin to bypass the package exports map (avoids the ~100MB TUI graph the adapter skips), provider SDKs kept lazy/external, sha256 sidecar for dep-keying. C0 mitigations baked in: import.meta.url pinned to projected guest path; clipboard native-addon require made unreachable (DISPLAY=''). - package.json build chains build:snapshot; tsconfig excludes the esbuild-only entry. Validated (host, CJS harness): 13/13 exports populate, ~201ms eval, 880 modules inlined, 7.6MB. Traced top-level fs footprint = 2 deterministic package.json reads only (no net/ sockets/timers/native addons/per-session config). Artifact (dist) is gitignored. Step 2a of the agent-SDK snapshot goal. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
