Validate interpolated scenario parameters — validate_scenario

Runs a set of post-interpolation consistency checks over the numeric / bounds / map parameters of a scenario and reports any issues. Checks:

NA index columns: no NA in a parameter's dimSets id columns. When fold = TRUE, NA is permitted only in the trimmable dimensions (region / slice / vintage, which fold encodes as wildcards); when fold = FALSE, no NA is permitted in any id column.
Schema: data columns match the declared dimSets (plus value, and type for bounds).
Duplicate keys: no duplicate id tuples.
Map vs parameter (correctness): every tuple of a value map is covered by its source parameter; a missing value would otherwise be silently replaced by the solver default.
Parameter vs map (efficiency): value parameter rows lie within the union of their maps (no orphan / out-of-domain rows). After trimming this must hold exactly.

Usage

validate_scenario_parameters(
  scen,
  fold = TRUE,
  action = c("warn", "stop", "silent")
)

scen: scenario.
fold: logical; whether the scenario is folded (NA wildcards allowed in trimmable dimensions).
action: one of "warn" (default), "stop", "silent": how to report issues.

(invisibly) a data frame of issues with columns parameter, check, detail.
