v0.20.1

Fixed

• The flash_ansr_hybrid adapter builds again. Its builder read emission from the Flash-ANSR
  adapter, which has not carried it since the flash-ansr 0.17 port made emission a sampling policy
  of the flash_ansr block; every hybrid config failed at build time with an AttributeError. The
  builder now takes emission from the flash_ansr block, as the Flash-ANSR builder does.
• scripts/make_hybrid_config.py writes configs this release can run: adapter type
  flash_ansr_hybrid (not the retired flash_ansr_pysr); a pysr: block holding only
  PySRSettings fields, since PySR runs in-process (the worker-protocol keys and the --pysr-python,
  --worker-log and --engine options are gone); draws instead of choices; and
  ranking: {mode: mdl}, the two-part code, instead of the fixed mdl_strength: 1.0e-2.

Changed

• Timing read-out: failures do not count towards the time. scripts/timing_readout.py drops
  every row that carries an error or prediction_success: False, whether or not a fit_time was
  recorded, so the reported seconds are the mean over the problems a method answered. Before, a fit
  that returned without a surviving candidate was still counted.
• scripts/site_export_v2.py publishes no as-run wall clock: fit_time and generation_time
  are no longer release metrics; the only time a release carries is the reference-machine table.

Added

• scripts/timing_queue_solomon.sh: RUN_PYSR=0 and RUN_NESYMRES=0 defer the PySR-alone and
  NeSymReS rows of the timing queue.
