Evergreen TreeSelected component

Fills snow_lim_patch. The stable path and origin retain Helsinki migration lineage, while the record declares target land_cover.evetr, name "Evergreen Tree", place generic, representativeness generic, applicable_scale land_cover, source jarvi2014 and method literature.

Evergreen TreeSelected component

Fills vegetation_growth. The record declares target land_cover.evetr, place helsinki and representativeness city, and is named "Evergreen Tree"; its source field reads jarvi2014.

Fills ohm.winter_wet and ohm.winter_dry. The record declares target ohm_coefficients and is named "Mixed Forest [20] McCaughey (1985)"; its source field reads grimmond1991b, it declares method fitted, it carries no season_label and it declares no place or representativeness.

Assessment findings

Composite identitysupported
The composite is named "Broad leaf" and declares place tropics with origin "Tropics" and representativeness regional. The label names a leaf form rather than a place or a source, so the tropical claim rests entirely on the place and origin fields; db/places.yml gives tropics a name and nothing else, with no lat, lon, koppen or country field. The label does not misdescribe what is assembled, but it carries none of the composite's identity either, which is why the place and representativeness findings below do the work.
Composite targetcuration required
The composite declares target land_cover.evetr. Every component declares that same target except two: biogen_co2 takes records/surfaces/common/midwest-usa--schmid2000--biogen-co2, declaring target land_cover.common, which docs/FORMAT.md defines as the surface-agnostic class, and the OHM positions take records declaring target ohm_coefficients. leaf_area_index and leaf_growth_power both declare lai.lai_type 1, which satisfies the leaf_area_index coupling rule in schema/parameter_groups.yml, which makes an archetype whose two LAI components carry different lai_type values internally contradictory. The season mapping is mixed and needs a decision. summer_wet and summer_dry take records/ohm/generic--ward2016--all-vegetation, which declares season_label Summer, so those two positions agree with the record's own declaration; winter_wet and winter_dry take records/ohm/generic--unreferenced--all-vegetation--mixed-forest-20-mccaughey-1985, which carries no season_label at all, so the winter positions take a coefficient set never declared for a season, from a different source, alongside a summer multiplier sourced to ward2016. In a composite whose place is Tropics the summer/winter split is itself questionable, and a maintainer has to settle what the four positions should carry.
Own parameter valuesnot applicable
The composite declares no parameters of its own, so every value it delivers is the component's.
Composition rationalenot applicable
The composite claims no composition source, and the repository records no published rationale for this assembly. The components' own sources belong to their evidence assessments, not to this review.
Place applicabilitycuration required
The composite declares place tropics, and not one component declares a tropical place. Six are generic, one is regional SE England, one is site-scoped Swindon, one Zurich, one Morgan-Monroe State Forest, one Helsinki, and the two OHM records declare no place at all. The biogen_co2 component is a single Indiana tower site named "Mixed Hardwood Forest"; snow limit is a generic Järvi default and leaf growth power a Zurich row. Whether a tropical default should exist on this evidence, and if so which rows should fill it, is a maintainer's decision rather than something the entries settle.
Representativenesscuration required
The composite declares representativeness regional, the class this database uses for a value offered as typical of a region. One of its thirteen components is classed city and three are classed site, so they stand in for a regional default. The Helsinki phenology record is city-classed; records/surfaces/evetr/zurich--stagakis-s2024--lai-power, records/surfaces/common/midwest-usa--schmid2000--biogen-co2 and records/surfaces/evetr/se-england--ward2016--water-storage are site-only. Six more are classed generic, the two OHM records carry no representativeness, and only leaf_area_index is regional. These scopes do not establish the composite's tropical regional claim.
Slot and season mappingsupported
An assembly of existing records into slots; the composite asserts no value of its own.
Completeness and uniquenesssupported
The composite fills all eleven named slots and the four OHM positions, which is the slot set every deciduous-tree, evergreen-tree and grass archetype in this database uses, so the assembly is complete. The porosity slot takes records/surfaces/evetr/generic--unreferenced--porosity, whose parameters block is empty and whose origin reads "Porisity only used for Deciduous Tree. This is a Dummy Variable", so that slot contributes no value by design rather than by omission. It is the only composite in the class declaring place tropics, and no other composite carries the same component set.

Scientific note

The assembly is structurally complete and the two LAI components agree on lai_type 1, but the composite's own claims are not supported by what it selects. It declares place tropics and representativeness regional, while its place-specific components are mid-latitude rows: SE England for leaf area index, Swindon for water storage, Zurich for leaf growth power, Helsinki for phenology, and Morgan–Monroe State Forest in Indiana for biogenic CO2. Albedo, emissivity, drainage, snow limit, maximum conductance and porosity are generic rows. One place-specific component is classed city and three are classed site, and they stand in for a regional default, which is the substitution the scale test exists to catch. The generic rows do not compound that problem. The OHM mapping does: the summer positions take a record that declares season_label Summer and the winter positions a record that declares no season at all, in a place where a summer and winter split is not obviously meaningful. None of this is a claim about any component's value; it is a claim that a tropical broad-leaf default cannot be read out of these rows, and a maintainer should decide whether the composite is rebuilt on tropical evidence, reclassified, or withdrawn.
