- search: native grep silently skips files above NATIVE_GREP_MAX_FILE_BYTES (4 MiB), so the RE2 virtual path dropped matches for large virtual resources (history://, big artifacts). searchVirtualResources now falls back to a JS RegExp matcher for oversized content (the pre-RE2 behavior) while keeping native parity for normal sizes; buildVirtualMatches still rebuilds context/ranges.
- ssh write: a trailing-slash target (ssh://h/dir/) is now rejected before staging, so the mkdir -p parent-creation no longer leaves a directory behind on a refused write.
- search: the native virtual probe capped matched-line detection at INTERNAL_TOTAL_CAP before range filtering, so a ranged virtual selector (ssh://h/log:5000-5100) over a file with >2000 earlier matches returned nothing. The probe now uses the line-count bound for ranged resources so range filtering sees every hit.
- ssh write: writeRemoteFile staged into a temp beside the destination before creating parents, so writing a new nested path failed with 'No such file or directory'. It now mkdir -p's the parent before staging, matching local write, keeping the directory/special-file refusal checks.
- `read ssh://host/dir` lists a remote directory one level deep; `ssh://host/` lists the remote root
- add statRemotePath + listRemoteDir; resolve reads first and classifies on error (directory -> one-level listing, dirs-first, dotfiles included)
- directory resources carry isDirectory + immutable and expose no sourcePath
- search refuses a virtual (no-sourcePath) directory resource instead of grepping the listing text
- writeRemoteFile refuses a directory destination and cleans up its temp on that path
- buildSshTarget rejects destinations beginning with "-" (SSH argument-injection / local RCE guard)
- gate ssh:// read/search/write at the exec approval tier; substring scan covers search's pre-expansion delimited paths and write's hashline-wrapped paths
- validate the entire materialized buffer as UTF-8 instead of only the first 8 KiB prefix
- write peels read selectors (raw/conflicts) so it targets the same file read does, and rejects line-range/malformed selectors instead of silently stripping them
- write to a uniquely named remote temp; document symlink-replacement on write as a v1 limit
