## Thinking Path > - Paperclip coordinates work for autonomous companies. > - A run needs a workspace view before execution starts. > - That view now needs to cover one anchor project and more referenced projects. > - Those extra workspaces must stay separate and must not change the anchor path when the feature stays off. > - This PR threads plural workspace data through run prep behind a default-off kill switch. > - It also keeps extra project workspaces isolated and makes the realization contract round-trip the new shape. > - The benefit is safer run prep for referenced projects without changing the current default path. ## Linked Issues or Issue Description This PR does not link a public GitHub issue. It follows the internal run-prep task for plural referenced-project workspaces. Problem: - Run prep resolves the anchor project today, but it does not yet carry each referenced project into the run workspace view. - That gap blocks runs that need a second repo or sibling project during preparation. Proposed solution: - Thread a plural workspace result through run prep. - Keep the anchor path unchanged when the kill switch is off. - Resolve each referenced project into its own managed checkout directory when the flag is on. Alternatives considered: - Keep one shared workspace and layer the extra repos into it. Rejected because it would blur isolation and make failures harder to bound. - Upload the extra workspaces immediately. Rejected because this PR only prepares the data path. Roadmap alignment: - This change sits in the workspace and sandbox path. - It matches the roadmap work on workspace strategy and cloud or sandbox agents. ## What Changed - Added `additionalWorkspaces[]` to the run workspace result. - Split workspace resolution into an anchor path and an optional referenced-project path behind `PAPERCLIP_MULTI_PROJECT_WORKSPACE_SYNC`. - Kept per-project failure isolation so one bad clone does not stop the run. - Keyed managed workspace directories by `projectId` so sibling workspaces stay separate. - Added `additionalSources[]` to the workspace realization request and kept read and write paths backward compatible. - Added tests for the anchor-only path, the new workspace shape, and the per-project directory rule. ## Verification - `pnpm --filter @paperclipai/server run typecheck` - `pnpm --filter @paperclipai/shared run typecheck` - `pnpm --filter @paperclipai/server exec vitest run src/__tests__/heartbeat-project-env.test.ts` 21/21 - `pnpm --filter @paperclipai/server exec vitest run src/__tests__/workspace-runtime.test.ts` 98/98 ## Risks Low risk. The new path stays behind a default-off kill switch, so the anchor flow does not change when the flag is off. The main risk is a bad referenced project clone. That case now drops only the affected project and keeps the run alive. The shared type change also needs every consumer to use the new array field where extra workspaces matter. ## Model Used OpenAI Codex (GPT-5; exact internal model ID not exposed in this environment; tool use enabled) ## 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 (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) 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> |
