13.7.9 (2026-06-05)

Bug Fixes

• libecalc: compute INDIVIDUAL_ASV_RATE per-stage boundary against realistic upstream inlet (#1597) (4425d9a)
• libecalc: reset recirculation inside AntiSurgeStrategy.apply() (#1594) (b9587d2)
• libecalc: surface stonewall failure from upstream-choke pressure control (#1599) (1bad9b7)
• libecalc: tighten Solution.combine semantics and clean up OutletPressureSolver (#1609) (1e88d67)
• libecalc: use speed-aware stonewall bounds in common-ASV evaluation (#1605) (194a505)
• process: binary search returns last accepted value instead of arbitrary midpoint (#1589) (3a0ddb0)

Miscellaneous Chores

• add process simulation yaml builder (#1603) (e0e6544)
• add process unit yaml builders (#1600) (0c0f3ba)
• add yaml builders for inlet streams and predefined fluid models (#1601) (c25c15a)
• bug in yaml mapper assumed process_units had name attribute (#1598) (d733f96)
• skip blowing up exception when it is expected (#1595) (4cd7c0d)
• upgrade dependencies for week 23. Auto-generated by devCalc (#1606) (7f19646)

Code Refactoring

• extract production solver assembly from test-only builder (#1596) (b2df1db)
• libecalc: lift inline recirculation resets into PressureControlStrategy.reset() (b9587d2)
• replace yaml compressor stages with process units in pipeline (#1591) (9f47f9e)

Tests

• use fixture factories instead of functions directly (46f5f75)
