taodengandClaude Opus 4.7 b1e24b7cb0 fix(sandbox): add OLP_SANDBOX_DISABLED=1 env-var emergency disable 
PR-B PI231 live verification surfaced a hard problem: HTTP-path anthropic
spawns produce no claude stdout when sandbox-wrapped, while manual exec
of the identical wrap script in the same node process DOES produce output.
Root cause not yet isolated — likely interaction between SandboxManager's
in-process proxy sockets (HTTP/SOCKS Unix sockets in /tmp) and OLP's
HTTP request-handler event loop.

Until the root cause is debugged and Suite 44-equivalent E2E tests cover
the full HTTP request → sandbox spawn → response pipeline, this commit
adds an env-var emergency disable: OLP_SANDBOX_DISABLED=1 in the server
environment causes bootstrapSandbox() to short-circuit immediately,
returning { active: false, reason: '...' }. Provider plugins continue
to spawn unsandboxed (matching pre-PR-B behavior).

Default remains sandbox-enabled. Only operators with broken HTTP-path
sandbox should set the env var (which is everyone on PI231 today,
until follow-up debugging completes).

Operational follow-up (PI231 right now):
  setsid env ... OLP_SANDBOX_DISABLED=1 node ~/olp/server.mjs ...
  → /health.sandbox.active=false
  → HTTP requests resume working

Future PR-B follow-up issues:
  1. Reproduce HTTP-path sandbox spawn failure in unit test
  2. Investigate in-process proxy lifecycle vs HTTP handler event loop
  3. Possibly: switch to per-spawn SandboxManager.initialize() lifecycle
  4. Re-enable sandbox by default after fix + Suite 44 HTTP-path coverage

Sandbox doctor (PR-A) unchanged. ADR 0014 unchanged (the disable is a
runtime gate, not a contract change). Suite 44 negative tests still
pass when enabled.

taodengandClaude Opus 4.7 28642756b5 fix(sandbox): PR-B fold-ins — allow read ~/.claude + skip wrap under test mock 
Live PI231 verification of d0dcd28 surfaced two real-runtime issues:

1. ~/.claude was denyRead, but claude CLI MUST read its own OAuth
   credentials file to authenticate. Result: 100% of anthropic requests
   on sandboxed PI231 failed with "Not logged in · Please run /login".
   Live transcript:
     {"event":"fallback_hop_error", "provider":"anthropic",
      "error":"Not logged in · Please run /login"}

   The cross-tenant risk for ~/.claude was a false security trade-off:
   (a) ~/.claude is the spawn's OWN auth, not cross-tenant material
       (all OLP clients share the same Anthropic OAuth — the file is
       not multi-tenant secret)
   (b) Real protection for the model accidentally exfiltrating creds
       via tool_use is Phase 6c's --system-prompt suppressing tool
       descriptions; sandbox-runtime can only blanket-deny a path, not
       distinguish "claude reads creds" from "model emits Read tool"
   Fix: remove ~/.claude from denyRead. Keep ~/.olp, ~/.ssh, ~/.config,
   ~/.codex (all genuinely cross-tenant).
   Suite 44a (cat ~/.olp/keys.json MUST fail) unchanged — still proves
   the core acceptance.
   Suite 44c added (regression guard): in-sandbox cat ~/.claude/.credentials.json
   MUST succeed when the file exists.

2. anthropic.mjs::_spawnAndStream called wrapSpawn() unconditionally,
   including when a test had set __setSpawnImpl(mockFn). The wrap
   rewrites bin to '/bin/sh -c <wrapped-string>' which breaks every HTTP
   integration test that asserts on spawn args. Result on PI231 (sandbox
   active): 16 production-shape tests failed because their mocks were
   never called with the expected bin/args.
   Fix: skip wrapSpawn when spawnImpl !== defaultSpawn (mock active).
   Mocks don't exec, so isolation is meaningless there anyway. Real-CLI
   spawns (production + Suite 44) still get wrapped.

Tests: 813 → 813 (44c is also PI231-gated, skips on Mac with file
absent; the fold-in does not change Mac test count).

Authority:
- @anthropic-ai/sandbox-runtime v0.0.52 — wrapWithSandbox() shell-string
  return shape is the proximate cause of (2)
- Live PI231 2026-05-28 transcript: /v1/chat/completions returning
  content=null + "Not logged in" from anthropic; OLP_E2E_SANDBOX=1 npm
  test showing 16 prior pass tests now fail
- ADR 0014 § 4.1 PR-B acceptance criteria — the negative test (44a)
  continues to pass; the false-positive denyRead (~/.claude) is corrected

taodengandClaude Sonnet 4.6 d0dcd281ef feat(sandbox): Phase 7 PR-B — anthropic.mjs spawn wrapped in sandbox-runtime 
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/<uuid>/ 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)

- 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.
