"""Regression tests: a failed compression split must arm the failure cooldown.

Extracted from PR #98137's test file (author: vsd2807); two sibling unit
tests were dropped as duplicates of existing coverage in
test_compression_rotation_state.py / test_context_compressor.py, and the
timeout-reconciliation tests were not carried because that production path
was not salvaged (blocking review on #98137).

Issue #97948 symptom B: without the cooldown, the turn after a
session_split_failed abort immediately re-runs the identical doomed
compression.
