| CClimateFileReader | Stateful forward-only daily climate-file reader with one month cache. One owner serializes open/lookup/close; no concurrent queries.

Serialize all access; advance mutates queues, abstraction, optional SWE and context balance totals. Stored float32 grid rows grow for the whole run; no streaming eviction/rollback.

| CQueuedSourceDelivery | |
| CRunoffSoA | |
| CRunoffSolver | Owned three-pool non-LID reservoir, native soil state and completed routing history. Initialize against one compatible model before use. Geometry is cached; execute mutates both owner and context, invokes an optional borrowed callback, and is not a transaction. Completed-source drivers must trial copies and publish after all coupled water owners accept. Serialize all mutation, borrowing and archives |
| CRunoffSourceForcing | |
| CSourceAtmosphericLedger | |
| CSourceClockGroup | One weakly connected runoff/LID/snow-transfer component. subcatches/lid_usages contain model indices; completed_end is accepted elapsed seconds. pending contains staged forcing only, never committed water state |
| CSourceClockGroups | |
| CSourceForcingInterval | Piecewise-constant forcing over [start,end) in elapsed seconds. month is zero-based; infil_factor/recovery_factor are monthly dimensionless multipliers. sources follow the owning group's ascending subcatchment order; rain/pet/raw_precipitation are internal ft/s, not project rainfall units |

| CSourcePollutantLedger | |
| CSourceSurfaceReturn | |
| CSourceWaterDelivery | |

| ►CSourceWaterDriver | Owned completed-source water/snow and conservative-pollutant trial driver. Context and kernel histories are copied; callbacks are borrowed synchronously. One owner serializes initialization, crediting, trials, reads and checkpoints. Stage advances private runoff/LID/snow state; commit adopts it with its group clock. Spatial receivers/hydraulic routing must settle separately. Liquid source and solid/liquid snow balances are distinct and paired, not double-counted rain. Qualified pollutants are conservative source-pool mixtures with drain removal; no land-use buildup/washoff, lumped groundwater, age/heat/reactions or production hot-start initialization is supplied. Private accepted-boundary restart requires a matching model and publication with paired source/surface/engine owners |

| CFluxes | Integrated accepted point exchanges and final thermal diagnostics. Water depths m and energy kJ/m2 cover the whole requested interval. Temperature Celsius and albedo are final accepted substep values, not interval averages. steps counts accepted leaves; retries counts successful binary splits |
| CForcing | Held point meteorology over one requested interval. seconds is duration, precipitation integrated liquid-equivalent m, temperature Celsius, wind m/s, humidity [0,1], incoming radiation W/m2, cosine [0,1]. Catch and drift apply to snowfall; snow_fraction=-1 selects temperature partition. Other fields remain held while advance splits time and apportions precipitation |
| CHeldState | |
| CLumpedFluxes | |
| CLumpedState | |
| CNativeState | Owned per-surface UEB predictions, accepted outputs and whole-model ledgers. Three surface columns per subcatchment; rain/snow caches are per subcatchment. Held water/energy use m and kJ/m2; global water/energy ledgers use m3 and kJ. Sample/completed clocks are elapsed seconds. last_seconds is the last call span; enabled column clocks can differ when source groups advance independently. Report arrays live in SnowSoA; one serialized owner coordinates both stores |
| CParameters | Point UEB material, radiation and integration parameters. Temperatures are Celsius, lengths m, densities kg/m3, heat capacities kJ/(kg K), conductivities kJ/(m K h), drainage/conductance m/h, max_step seconds. Fractions, age responses and stability are dimensionless; low_frequency retains the reference hourly convention. validate() checks all fields before public advance |
| CSite | Per-column environmental settings. forest is canopy fraction, drift a snow multiplier, pressure Pa, ground_heat prescribed W/m2 into the snow system, extinction_depth m. Public advance checks forest [0,1], drift>=0, positive pressure/depth and finite signed ground heat |
| CState | One owned point snow/active-soil energy and thermal-memory inventory. energy kJ/m2 may be signed, water m SWE, age dimensionless optical age, refreezing depths m. The duration-weighted history spans at most 24 hours. No forcing/runtime context is shared between independent point states |
| CThermalSample | One duration-weighted preceding thermal sample (seconds and Celsius) |
| CClimateSite | |
| ►CInfilBank | |
| CFactors | |
| CMeshSnow | Owned mixed degree-day/UEB snow on remaining mesh weather footprints. Geometry area is horizontal m2; cell slope/aspect are degrees. Water accounts are m3, energy kJ, point energy kJ/m2 and rates m/s. One owner serializes all mutation, borrowing and checkpoint/contact calls. Trial advance protects this snow owner, while shared context weather cursors/diagnostics can still change. Physical ground heat, cover-geometry energy and prescribed energy stay distinct |
| CMeshSnowConfig | |
| CMeshSnowGeometry | |
| CMeshSnowLedger | |
| CMeshSnowRow | One authored pack selection and optional site/geometry override. Missing optionals inherit lower-precedence scope values; explicit zero is a real override. forest is fraction, drift dimensionless, ground_heat W/m2, extinction_depth metres, slope degrees and aspect degrees clockwise north. pack is an unresolved model name or normalized NONE token |
| CRadiationSource | |
| CSnowConfig | |
| CSnowInputs | One element's interval weather, with SI point-input units. dt_s is seconds; rain_m/snow_m are interval water-equivalent depths (not rates), Ta_C is Celsius and wind_ms m/s. rh is fraction, Qsi/Qli/Qg incoming W/m2; cosine and horizontal-radiation factors are dimensionless. gamma/ea retain native degree-day F^-1/in-Hg conventions. Individual models may ignore fields |
| CSnowModel | Polymorphic point and native-batch snow boundary. One owner serializes state mutation and buffer use. Configure compatible model geometry/materials after allocation; a successful allocation alone does not establish physical snowpack parameters. Derived methods define failure and payload validation; this interface supplies no universal rollback/status |
| CSnowOutputs | Point snow results: interval depths metres and model-specific thermal state. melt_m can include pack drainage, mixed rainfall and instant plow liquid, not only phase change; throughfall_m is bypass rain. swe_m includes retained snow/ free water, cover_frac is dimensionless. Temperatures C, energy kJ/m2. Derived implementations specify which thermal fields are available/defaulted |
| CSnowpackConfig | |
| CSolarIntegral | |
| CSourceSnow | Per-source-group native/UEB snow ownership and cumulative water balance. Liquid source delivery, stored pack water and atmospheric losses are separate ledgers. Caller supplies a private context/trial and serializes all operations; mutations are immediate and exceptions do not roll back a partially advanced snow owner. SourceWaterDriver provides the enclosing accepted/trial boundary |
| CSourceSnowLedger | |
| CSurfaceElement | |
| ►Nsurfacespecies | |
| CBlock | |
| ►Ntrace | |
| CFlowTracer | Own topology, SI hydraulic averages and steady-flow trace preparation state. The C API validates topology/options and supplies aligned arrays. Direct C++ callers must preserve those invariants: valid endpoint indices, finite lengths, na.size()==nodes.size(), la.size()==links.size(), and valid positive solver tolerances/iteration limits. Serialize all access to one tracer; methods can mutate error/state and invoke synchronous callbacks. No internal transaction or C++ exception boundary is supplied; C wrappers catch most analysis exceptions |

Serialize all access to one tracer; methods can mutate error/state and invoke synchronous callbacks. No internal transaction or C++ exception boundary is supplied; C wrappers catch most analysis exceptions |
