=== Assistant: Good catch. ===
Good catch. We can make the default sensitive enough for ~40-char loops without turning it into a false-positive machine by making the threshold length-dependent.

==== ### ====
* Split on completed lines (\n).
* Normalize by: - strip leading/trailing whitespace - collapse internal whitespace runs (optional but recommended)
* Ignore empty/whitespace-only lines.

===== Use a minimum length of 32 chars, and vary the repeat threshold: =====
* If len(line) >= 64: trigger at repeat_threshold = 8
* If 32 <= len(line) < 64: trigger at repeat_threshold = 12
* If len(line) < 32: ignore (default)

This catches your 39-char case quickly (12 repeats) but remains conservative.

===== - min_output_chars_before_check = 256 (down from 512, since shorter lines can loop early) =====
* Additionally, don’t start counting repeats until you’ve observed at least 2 completed non-empty lines (cheap sanity check).

===== - Cancel request → FAILED(reason="repeated_line_loop") =====
* Record repeated line snippet (truncated) + repeat count in status/debug.

If you want it even more conservative, we can add a tiny heuristic like “only count repeats for lines containing at least N alphanumeric characters” (e.g., ≥ 12), but the length-tiered repeat threshold above is usually enough.
