The provider must not fail a lease when the host lacks bubblewrap support. The wrapper must stay advisory only. It must not change the security model. ### Proposed solution Add a pure command builder for the advisory wrapper and non-throwing probes for bubblewrap and sandbox uid or gid data. Store the probe result on the lease metadata so later steps can make a stable choice. Keep the execution seam unchanged. ### Alternatives considered Do nothing and keep the current execution seam unchanged. That path gives no signal when a file change is not durable. This pull request adds the signal without changing runtime behavior. ### Roadmap alignment This work fits the Daytona sandbox provider path and keeps the advisory wrapper outside the execution seam. It does not change the current security model. ### Additional context The wrapper is advisory only. It adds no security. The read-only root is a feedback signal. ## What Changed - Added `buildBwrapCommand` as a pure string builder for the advisory wrapper command. - Added `detectBwrapAvailable` and `detectSandboxUidGid` as best-effort probes that never throw. - Stored `bwrapAvailable`, `sandboxUid`, and `sandboxGid` on the lease metadata in the acquire, resume, and probe hooks. - Added a README section that describes the advisory wrapper model. - Kept the execution seam unchanged. ## Verification - `vitest run` for `packages/plugins/sandbox-providers/daytona/src/plugin.test.ts` - The run passed all 106 tests, including the new builder and probe coverage. - The standalone `tsc` run showed only the known baseline noise that already exists on `master`. ## Risks - Risk is low because the execution seam does not change. - The new wrapper stays advisory and does not alter the sandbox security model. - The probe results only add metadata and do not fail the lease on missing host support. ## Model Used OpenAI Codex, GPT-5, tool use. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used with version and capability details - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links - [x] My branch name describes the change and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
