Grid Copy/Cut now writes the selected real cells through VS Code’s system clipboard API using the active delimiter. Ordinary strings stay unquoted even beside complex or empty values; only values requiring escaping receive CSV quotes. The extra append row is never copied or cut. Copying that row alone leaves the clipboard and document untouched, while real empty cells and interior empty rows remain in the output.

All keyboard, native-event and context-menu routes share this behavior. Cut clears source cells only after the clipboard write succeeds and preserves newer edits if the document changes meanwhile. Find/Replace and cell text edits retain native clipboard behavior. Addresses #81, #95 and #105; stacked on #109. No settings or commands added.

Validation:

• Node 20.20.0: compile and all 153 tests pass; lint has 0 errors and existing warnings; diff checks pass.
• Shipped-webview tests cover columns, ranges, Select All, every Copy/Cut route, ghost-only selections, empty files, real blanks and remote chunk boundaries. Full-source row metadata avoids dropping the last loaded real row.
• Exact provider clipboard output and codec roundtrips cover per-value escaping, multiline fields, alternate delimiters in later quoted fields, whitespace, literal quotes and custom delimiters. An independent review passed 40,000 additional deterministic roundtrips. Unknown arbitrary custom source delimiters remain inherently ambiguous when pasted into a different format.
• The maintainer’s native check.csv tests passed clipboard operations through all tested modes on their local setup. This accepts the local Copied table does not saved into clipboard #105 smoke test; the original reporter’s environment has not been reproduced.
• Combined Chromium QA copied 151 real rows from a selected column, excluded the ghost cell and sent no new clipboard request for a ghost-only Copy. Source and disk stayed unchanged.

Clipboard output remains text-only delimited data. Values containing separators, quotes, line breaks, surrounding whitespace or explicit emptiness can still require CSV escaping in ordinary text inputs.
