 Clipboard checks use isolated providers rather than reading or overwriting the desktop clipboard.

+Diff checks cover staged category/filter navigation, stale request cancellation, row alignment, read-only buffer isolation, and rendered panes. Repository integration fixtures exercise Git and Git-backed jj, advertised but unfetched remote branches/bookmarks/tags, imported historical commit/change IDs, conflicts, unusual paths, binary/mode/link/submodule changes, and unchanged active metadata. Remote fixtures are local bare copies; they never push. Git fixture identities and commit dates are fixed.

 ## Performance and process limits

 - Undo uses full-buffer snapshots and movement scans the current line. This favors straightforward correctness over large-file performance.

 - PTY throughput alone cannot prove terminal presentation stays smooth: capture the editor and terminal while the user reproduces a pause. Synchronized-output commands must not reach the terminal during frame computation, even when individual frames and queued-input catch-up appear fast.
 - Annotation coordinate validation fast-paths ASCII grapheme lengths using byte lengths with CRLF pair accounting, retaining Unicode segmentation for non-ASCII text. Validation remains atomic and still checks every token; large Unicode buffers or diagnostic batches can require foreground work.
 - Legacy synchronous plugin invocation may pause input for up to 500 ms before a host timeout. Async plugins opt into background replies; pending requests and transport queues are bounded. Config/plugin startup has a 2-second deadline per host. Buffer context/document snapshots must fit within a 4 MiB JSON frame; a too-large frame disables that plugin, not editing.
+- Repository diff currently requires Unix subprocess-group cancellation and Git-backed jj (or Git alone). Each file is limited to 16 MiB; each subprocess output stream and Working/conflict snapshot to 64 MiB; each command to 60 seconds. Limit, transport, and non-commit-tag errors are explicit rather than silently truncated. Temporary comparison stores are removed when the diff closes.
