  "works": "About 150 JavaScript SDK calls from new Node scripts against a local Store. Unicode, deep, binary and large files round-tripped; an 8-deep fork chain behaved correctly; typed-array, DataView and 30 MB writes worked with typed, clear refusals. An apply that failed at step 3 committed nothing and named the failing index. Merge correctly reported binary, modify/delete, add/add and line conflicts, and a .lww rule cleared only its file. 20 parallel writes to different paths all landed; 10 parallel writes to one path gave 1 commit and 9 Conflict errors. Diff paging with a cursor worked.",
  "breaks": "Confirmed from the first run: init as a normal user fails with an undocumented 'must run as user 0' error and leaves the project entry behind so a retry says Exists; opening an unknown project returns Failed with a raw OS error instead of NoSuchProject; invalid project names (uppercase, or 64 characters) are reported as 'a project name is required'; init on a missing source folder returns a raw internal debug dump with local paths; writing into a missing folder (and removing or editing a missing file) returns Content(PathNotFound) with no path named. New: init with a relative folder path gives the same raw debug dump; writing under a path that is an existing file returns code Unknown (mkdir there correctly returns NotDirectory); publishing with a commit id from another branch returns HeadMoved with a raw debug structure; a line conflict in a 4.7 MB plain-text CSV is reported as kind 'binary' with no hunks; publish replaces main's whole view, so a branch forked before someone else's publish silently drops that publish's files from main (only shown in the response's overwrote list; the bundled skill documents it, the SDK guide and README don't); an invalid glob pattern returns an empty result instead of an error.",

   "Prescreen caution: Init and Sandboxes run as root by design. Two medium-severity advisories were published by the project on Oct 29, 2026 for versions up to 1.1.0 with no fixed release yet: one can leave a mounted FUSE Workspace permanently unusable, and one lets a local process crash the runtime's loopback worker without authentication. Both are denial-of-service issues; until a fix ships, avoid relying on Workspaces for critical work and don't run it on shared multi-user machines. Not an MCP server. No malware signs, not on the malware list.",
   "Same public cautions as the first run: two medium denial-of-service advisories published by the project on Oct 29, 2026 for versions up to 1.1.0, no patched release yet (re-checked on GitHub). Init and Sandboxes need root, so don't treat it as isolation for untrusted code. No new security finding in this check."
