Sort constraint/control assembly for deterministic Jacobians, keep live z_ua on legacy HX, and add generic Fixed/Free UI assist without removing Z factors.

Checkpoint incomplete calibration work (cond SDT green, evap SST failing) plus related solver/UI changes so the next pass can fix and extend safely.

Mass flux used all plate gaps instead of half the pack per fluid, underestimating G and making ΔP look like zero in the UI (0.000 bar). Also show ΔP in kPa/Pa and sync the web example.

Fixes the UI compile break from referencing an undefined helper when showing z_dp and other solved actuators.

Align the TypeScript API with the Rust SolvedVariable payload so z_dp and other free actuators can be displayed after solve.

Replace isobaric 4-port closures with SimplifiedChannel (default) and Martin1996 DP models so z_dp and UI dp_correlation actually affect the Newton solve.

Capture uncommitted solver robustness work (regularization, domain errors, linear solver lifecycle, tube DP/MSH), web workbench updates, and synced BMAD skills across IDE agent folders before starting BPHX pressure-drop.

Add analytic derivatives and C1 tests for smooth_max/min/clamp, document epsilon/width guidance, and declare flow_regularization as the HX reference pattern without changing component physics.

Bring the root README, technical manual, and CLI guide in sync with
post-CM1.x state (m,P,h), Modelica Fixed/Free, and current component catalog.

Ship the Next.js cycle editor with CAD chrome, technical HX symbols, Fixed/Free boundary guidance, and secondary water/air pressure drop support in the solver stack.

Clean up unused BMAD workflow, agent, and command files across all IDE
configurations (.agent, .clinerules, .cursor, .gemini, .github, .kilocode,
.opencode) and internal module files (_bmad/bmb, _bmad/bmm).

Removed mathematical singularity in HeatExchanger models (q_hot - q_cold = 0 was redundant) causing them to incorrectly request 3 equations without internal variables. Fixed ScrewEconomizerCompressor internal_state_len to perfectly align with the solver dimensions.
- Created DOCUMENTATION.md covering core philosophy, modules, and platform specifics.
- Created EXAMPLES_FULL.md with complex multi-platform usage scenarios.
- Updated README.md and docs/index.md to centralize documentation links.
- Added port_mass_flows to Component trait and implements for core components.
- Added System::check_mass_balance and integrated it into the solver.
- Restored connect methods for ExpansionValve, Compressor, and Pipe to fix integration tests.
- Updated Python and C bindings for validation errors.
- Updated sprint status and story documentation.
- Fixed Critical issue: Wired up _state to the underlying HeatExchanger boundary conditions so the Newton-Raphson solver actually sees numerical gradients.
- Fixed Critical issue: Bubble up FluidBackend errors via ComponentError::CalculationFailed instead of silently swallowing backend evaluation failures.
- Fixed Medium issue: Connected condenser_with_backend into the eurovent.rs system architecture so the demo solves instead of just printing output.
- Fixed Medium issue: Removed heavy FluidId clones inside query loop.
- Fixed Low issue: Added physical validations to HxSideConditions.
