Sasha Studio release notes: v1.0.1442 to v1.0.1443

Executive Summary

Administrators can give each member No access, Read, or Read & write for whole knowledge projects. With shared writes enabled, members can create and edit documents through Claude in the projects assigned to them. Document content stays on disk.

Major Features & Improvements

  • Set project access in Settings → My Account → User Management → member menu → Knowledge Grants.
  • Read & write permits document creation and editing. Existing grants remain read-only.
  • Downgrading or removing a grant applies to existing connections on their next request.
  • Member homes remain private; another member’s home cannot be assigned as a shared project.

Stability & Reliability

  • Managed filesystem writers coordinate across requests and processes, including Git operations, startup maintenance and scheduled Claude runs.
  • Shared edits retain version conflict detection, repeat-request handling and crash recovery.
  • Project retirement settles unfinished operations together with retirement metadata.

Developer Experience & Docs

  • PRD 20 §10.0c records the filesystem-first shared-project scope.
  • The writer audit, Linux runtime proof and deployment record document the supported boundary and verification.
  • The internal acceptance probe supports writable shared projects and read-only refusal checks.

Upgrade Notes

  • Shared writes default to disabled and require the independent MCP_KNOWLEDGE_SHARED_WRITES_ENABLED=true flag, a dedicated handle key and supported Linux/ext4 storage.
  • Deploy the guarded image before enabling shared writes. Each member also needs an explicit project write grant and a connection with knowledge write scope.
  • Trusted interactive staff shell/CLI remains outside managed-writer coordination. Intentionally detached automation is outside the supported release boundary.
  • This release does not enable global unified authorization or change other instance deployment pins.

Changelog Summary

Source range: v1.0.1442..v1.0.1443.

Member project grant levels, shared filesystem create/edit, managed-writer locking, subprocess lifetime handling, retirement recovery, UI concurrency protection and expanded acceptance evidence.

Looking Ahead

Git history/restore, additional document mutations and permissions for individual subfolders remain future work.
