solve_internal_ballisticsSolve one internal-ballistics point: modeled velocity/energy/pressure for an exact cartridge+bullet+powder+charge specification, wrapped in the non-removable safety envelope (charge range, closed-enum warnings, assumptions). Returns the SAME envelope as POST /v1/solve. Measured…
generate_load_ladderPREFERRED for load development: generate a work-up ladder (>=5 rungs required — coarser requests are refused LADDER_TOO_COARSE, never silently interpolated) from the published-reference or charge-only bookends down, with per-rung trajectory nodes and the full safety envelope. Re…
trajectoryTrajectory / drop table: point-mass (3-DOF) exterior solve fed by the modeled muzzle velocity for an exact cartridge+bullet+powder+charge spec (or an explicit muzzle_velocity_fps override). Returns range rows (drop, velocity, energy, windage) plus the model assumptions. Beta key…
get_cartridge_specLook up ONE cartridge in the served component database (census: mode != 'hidden' AND geloescht == 0) by name, CIP name, alternate name, or id — returns the published dimensional spec (pmax_bar, case volume, bore/case dimensions, max OAL). Identity + published dimensional metadat…
list_powdersList propellants in the served database (optionally filtered by manufacturer substring), with the GRT attributes the solver uses (Ba, Qex). Identity + published dimensional metadata only — NOT load data (rights-class discipline): no charge/velocity/pressure values are served by…
check_component_compatibilityCheck whether a cartridge+powder pair RESOLVES in the served database and whether the published-reference corpus contains a row for the pair (nearest-bullet membership — the same membership that decides a ladder's basis). Answers membership and canonical identity ONLY; it never…
