From b21fdf5b94cda45645022836061c2acfb9266475 Mon Sep 17 00:00:00 2001 From: Chris Scott <99081550+chriswritescode-dev@users.noreply.github.com> Date: Wed, 14 Oct 2026 16:16:47 -0400 Subject: [PATCH 1/8] feat(sandbox): per-session sandbox VMs with resource settings and provider arbitration - Sandbox new root sessions by default with a per-session composer toggle; child sessions inherit their root session's mode (OM-82) - Run each sandboxed root session in its own microVM that mounts only the session's repository, with per-session CPU/memory overrides, Settings defaults, idle stop, and a cap on running VMs (OM-89) - Arbitrate shell sandboxing with other plugins (opencode-forge) through the shared opencode.sandbox-arbiter.v1 registry so exactly one provider sandboxes each call regardless of load order; fail closed on claim errors - Throw when another plugin rewrites a pinned sandbox shell setting - Tag sandboxed tool results with the owning provider and show it in the badge - Hint the agent to start Docker inside the VM only when OCM owns the session --- .../202610141200-session-sandbox-modes.ts | 14 + backend/src/db/migrations/index.ts | 2 + backend/src/db/session-sandbox-modes.ts
