From 7019294c63b1b77d15064ff6f0702d95e020cc42 Mon Sep 17 00:00:00 2001 From: dtzp555-max Date: Fri, 29 May 2026 10:43:53 +1000 Subject: [PATCH] feat(sandbox): Phase 7 Solution 1 implementation + opus 4.8 (#68) Implements ADR 0014 Amendment 1 (4-layer Solution 1) + ADR 0002 Amendment 9 (Provider ISOLATION contract) + opus 4.8 model. Fresh-context opus reviewer APPROVE_WITH_MINOR; 2 nit fold-ins applied. 813 unit tests pass. Known deferred coverage: Suite 44 PI231 E2E tests are placeholders under describe.skip pending Task #9 (PI231 prod-target validation). The load-bearing negative test ('in-sandbox cat ~/.olp/keys.json MUST fail') will be validated when Task #9 runs against the merged code.

It forwards messages between your client and a provider's LLM and returns the response. It does **not** execute tools (shell commands, filesystem reads, web fetches) on your behalf, and it has no plans to. + +When an agentic client (Cline / Cursor / Continue.dev / Aider / Hermes Agent / OpenClaw) needs to call a tool, that tool runs **on the client's host**.

The threat surface is bounded to "what the model can say in a message" — not "what the model can do on the server." +- **Stateless operation.** OLP runs the same code path for every request, regardless of which client is calling. Session state, tool state, and conversational memory all live in the client. See [`AGENTS.md`](./AGENTS.md) § "No conversation state". +- **Provider-CLI honesty.** OLP spawns provider CLIs (`claude`, `codex`, `vibe`) to talk to upstream APIs and translates wire formats via the IR. It does not extend those CLIs with new tools or capabilities — see [`ALIGNMENT.md`](./ALIGNMENT.md) Rule 2 (No Invention). + +A few clients (notably OpenClaw in certain configurations) can be wired to route their tool calls *through* the OLP server host rather than executing them locally.
