## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Storage plugins already own project storage and task checkout preparation. > - Core only selected these plugins through an explicit project policy. > - Installation could therefore leave new and existing projects on incompatible Core preparation. > - This pull request adds one generic manifest declaration and one shared effective-policy resolver. > - Project configuration shows inheritance while durable workspace bindings retain their owners. ## Linked Issues or Issue Description **Subsystem affected** Plugin contracts, project configuration, and execution workspace preparation. **Problem or motivation** An installed storage provider cannot become the company default. Projects without an explicit provider keep Core preparation, even when their execution environment cannot use a Core Git checkout. **Proposed solution** A provider declares supported `workspaceProvider.defaultForProjects` mode and strategy. Company-enabled installations supply inherited defaults. Explicit plugin selections and explicit Core/local (`storageProviderPluginId: null`) win. Conflicting defaults require an operator choice. The declaration and implementation contain no provider-specific identifiers. **Alternatives considered** Rewriting every project would lose the distinction between inheritance and overrides. Selecting by worker health would silently change storage on an outage. **Roadmap alignment** Extends the existing workspace and sandbox provider contracts. The roadmap has no duplicate default-provider implementation. Related public work includes #17243, which covers prepared execution directories rather than provider selection. ## What Changed - Add a validated generic default-provider declaration and document it in the SDK. - Resolve provider selection and Git defaults consistently in project responses, source selection, heartbeat source resolution, reservation, and preparation. - Keep stored policy separate from effective configuration. Add the normal project configuration selector for inheritance, explicit plugins, and Core/local. - Preserve existing local and plugin workspace ownership. Pin selection through preparation and keep provider failures visible. - Add database, API, manifest, heartbeat, and UI regressions. Update the verification maps. ## Verification - Targeted Vitest runs cover manifest validation, project defaults and API access, explicit overrides, existing ownership, new/imported task inheritance, heartbeat routing, source-free tasks, selection pinning during setup, and UI configuration. - Combined policy, provider integration, and heartbeat run: 58 tests pass; 60 unrelated cases excluded. After the final shared-provider fallback fix, all 47 policy tests pass, including shared and operator-mode regressions. - Server and UI TypeScript checks, SDK build, verification-map validation, credential-pattern scan, added-comment scan, and `git diff --check` pass. - A downstream integration uses this Core resolver and preparation service with a real storage hook and mocked remote infrastructure. A new Git project reaches the hook without a stored provider ID. - Standard Greptile and Apex both scored 5/5 on5d42998466. All review threads are resolved. - Final GitHub CI is fully green on5d42998466. Browser shard 3 initially hit a PostgreSQL deadlock during cleanup cancellation, which left an experiment flag enabled for a later test. A failed-job retry passed all 26 browser tests. The workflow completed successfully on attempt 2. Full final verification was delegated to CI at the user's request. - No live provider or hosted tenant run was performed. ## Risks - Installing one default-claiming provider changes effective selection for unconfigured projects. Existing explicit settings and workspace ownership remain intact; incompatible explicit settings fail clearly. - Each configuration/admission resolution reads installed plugin metadata and the selected company's enablement. Project list reads share one catalog query. Selection does not call workers or external providers. - Deploy the Core contract before any downstream manifest uses the declaration. No migration or backfill is required. A downstream immutable image pin must include this change before packaging its declaration. - No merge or deployment is authorized by this PR. ## Model Used OpenAI GPT-6 through Codex, with reasoning, repository tools, and code execution.
