-Programmatic debugging helper for `pdbp` REPL human-like
-interaction but built to allow `claude` to interact with 
-crashes and `tractor.pause()` breakpoints along side a human dev.
-
-Originally written by `clauded` during a backfiller inspection
-session with @goodboy trying to resolve duplicate/gappy ohlcv ts
-issues discovered while testing the new `nativedb` tsdb.
-
-Allows `claude` to run `pdb` commands and capture output in an "offline"
-manner but generating similar output as if it was iteracting with
-the debug REPL.
-
-The use of `pexpect` is heavily based on tractor's REPL UX test
-suite(s), namely various `tests/devx/test_debugger.py` patterns.
