"""
Tests for the autobuild HL-without-PHIB recovery (autobuild_hl_without_phib).

phenix.autobuild aborts when its data= MTZ carries Hendrickson-Lattman coeffs
(HLA-HLD) but no PHIB and use_hl_if_present defaults to True.  The recovery
retries with use_hl_if_present=False, keyed to the affected data MTZ so
command_builder merges it (and the post-assembly injection appends it) when that
file is reselected.

Two layers:
  * analyzer tests       - run anywhere (error_analyzer is stdlib-only).
  * command-string test  - the IMPORTANT one: asserts the rebuilt autobuild
                           COMMAND STRING actually carries use_hl_if_present=False
                           (where a file-keyed silent-drop would hide).  Needs the
                           full agent stack; skips cleanly if unavailable.

Run with: python3 tests/tst_autobuild_hl_recovery.py
