Main's 243c9182b1/a16fd675df/7142dc4580 added load_config_readonly sibling stubs across 38 files; our pruned versions of 11 of those files kept only the load_config stubs. Re-applied the pairing at every surviving site (26 patch()/setattr sites) — same return_value/ side_effect as the adjacent load_config stub. 494 tests green across the 11 files.

"""compression.proactive_prune_* — config parse seam for the proactive prune.
|
|
|
|
Mirrors ``test_compression_max_attempts_config.py``: the three knobs are
|
|
parsed in ``agent_init`` with the same hardened semantics (booleans rejected,
|
|
fractional floats rejected — not truncated, integral floats and numeric
|
|
strings accepted) and attached to the built-in compressor. Default is
|
|
0 / 8000 / 4096, i.e. the feature is OFF and behavior-neutral unless
|
|
``proactive_prune_tokens`` is set above 0.
