From d0dcd281ef4f4b38002aafbca2e208f1e54927f2 Mon Sep 17 00:00:00 2001 From: dtzp555 Date: Thu, 28 May 2026 17:26:34 +1000 Subject: [PATCH] =?UTF-8?q?feat(sandbox):=20Phase=207=20PR-B=20=E2=80=94?= =?UTF-8?q?=20anthropic.mjs=20spawn=20wrapped=20in=20sandbox-runtime?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Wraps the claude CLI spawn in @anthropic-ai/sandbox-runtime per ADR 0014 § PR-B. Achieves multi-tenant filesystem + network isolation: the spawned claude subprocess can no longer read ~/.olp/keys.json, ~/.claude/.credentials.json, ~/.ssh/, or any other per-client OAuth material. Only api.anthropic.com and statsig.anthropic.com are reachable; only /tmp/olp-spawn// is writable per spawn (ephemeral, UUID-scoped to prevent cross-request contamination). ## Authority citations - @anthropic-ai/sandbox-runtime v0.0.52 https://github.com/anthropic-experimental/sandbox-runtime dist/sandbox/sandbox-manager.js — SandboxManager.initialize(), wrapWithSandbox() dist/sandbox/sandbox-utils.js — getDefaultWritePaths() - 2026-05-28 spike report at /tmp/sandbox-spike/report.md on PI231: spike-anthropic.mjs (wrapWithSandbox call signature + NDJSON proof), spike-deny.mjs (cat ~/.olp/keys.json MUST fail) - OLP ADR 0014 § 2.1 PR-B, § 4.1 PR-B acceptance criteria - OLP ADR 0009 Amendment 1 § Caveats #3 (sandbox is cloud prerequisite) - OLP ALIGNMENT.md Rule 1 — provider plugin authority citation - cc-mem incident 2026-05-27 § 3 (multi-tenant OAuth token exposure via prompt injection) ## Files changed - lib/sandbox/manager.mjs (new): bootstrap + spawn-wrap layer. Exports: bootstrapSandbox(), isSandboxActive(), wrapSpawn(), __resetSandboxManagerForTests(). Config-at-boot model (one SandboxManager.initialize() at server start; per-request wrapWithSandbox() reads from already-initialized state). Transparent pass-through when inactive. - lib/providers/anthropic.mjs: spawn site wrapped via wrapSpawn({ bin, args, env, allowedDomains: ['api.anthropic.com','statsig.anthropic.com'] }). ADR 0009 Amendment 1 spawn args unchanged — only execution is wrapped. - server.mjs: bootstrapSandbox() called before server.listen(); startup banner logs sandbox.active state. /health.sandbox now includes active:boolean field (distinguishes "deps present" from "SandboxManager initialized and wrapping"). - test-features.mjs: Suite 43 (8 tests — manager unit: bootstrap state, idempotency, isSandboxActive, wrapSpawn passthrough, /health.active field) + Suite 44 (2 PI231-gated tests: 44a security negative test + 44b positive echo test, skipped by default, run with OLP_E2E_SANDBOX=1 npm test). - CHANGELOG.md, docs/adr/0014-sandbox-runtime-integration.md: PR-B status updated; ADR table + /health JSON example updated with active field. ## Test count 805 (pre-PR-B) → 813 (+8 Suite 43; Suite 44 skipped on macOS, runs on PI231) All 813 pass on macOS dev machine. 0 regressions. ## PI231 validation (required before merge — Suite 44) After apt-get install bubblewrap socat (ripgrep already present) + server restart: 1. curl /health → confirm sandbox.available=true AND sandbox.active=true 2. Real anthropic request → confirm stream-json still works end-to-end 3. OLP_E2E_SANDBOX=1 npm test → confirm Suite 44a (cat ~/.olp/keys.json MUST fail) and Suite 44b (echo SANDBOX_PROOF succeeds) Reviewer: must SSH PI231, run Suite 44, and confirm the ADR 0014 § 4.1 criteria. This commit is ready to push; do NOT push before Suite 44 transcript is captured.
