- Supports `:phylogenetic`, `:taxonomic`, and `:combined` modes, surfacing non-monophyletic / dispersed taxa and discordant clades.
- Strict raw `.jplace` evidence reader (`parse_jplace`) without defaulting missing `like_weight_ratio` values to `1.0`.
- Exact `faith_pd`, `clade_faith_pd`, `unweighted_unifrac`, and `weighted_unifrac` (`normalized = false | true`), verified against `scikit-bio` reference outputs.
- Indexed study-tree API used by the de novo cladistics builds (`src/server/routes/cladistics.jl`): `asv_tip_name` (content-addressed tip names), `parse_phylogenetic_tree` (Newick → `PhylogeneticTree` with a `tips` index), `clade_counts` (nodes × samples roll-up), `unifrac` (either a raw samples × ASVs matrix or an existing roll-up), and `analyse_phylogeny`, the single call that produces the JSON payload the UI renders.

- Gated behind an explicit `CladeCumulus Evidence Mode` switch on the Study `Trees` tab so standard workflows are never altered silently.

Define and enforce one rooting convention for Faith's PD.

analyse_phylogeny uses the parsed Newick root directly. The legacy path midpoint-roots trees with more than two root children. Therefore an unrooted, trifurcating input can produce a different faith_pd value, especially when a sample contains one active tip. The current payload reports no rooting status.

UniFrac should not be included in this claim. Both implementations aggregate edge partitions, so re-rooting should preserve those distances.

If the route must match the legacy result, midpoint-root the tree before indexed analysis. Otherwise reject non-bifurcating roots or document and enforce a rooted-tree requirement. A rooted = length(tree.nodes[tree.root].children) <= 2 field alone only reports the condition; it does not correct the Faith's PD value.

Review comment at @src/analysis/clade_cumulus.jl around lines 397 - 402:
Define and enforce a consistent rooting convention for Faith’s PD: midpoint-root
trees before the indexed analysis that calls _faith_pd_indexed so unrooted
trifurcating inputs match the legacy result. Do not change UniFrac handling as
part of this fix.
