For Aitchison ordination on a count matrix containing zeros, this call always throws a MethodError: Differential.replace_zeros declares the replacement fraction keyword as frac, not delta (src/analysis/differential.jl:992–995). Consequently, sparse microbiome data cannot reach CLR transformation or model fitting. Pass frac=cfg.replacement_delta to the existing helper.

For either UniFrac distance, _resolve_study_unifrac_tree returns the PhylogeneticTree produced by parse_phylogenetic_tree, but CladeCumulus.unifrac_matrix only accepts Union{PhyloNode,AbstractString} as its tree argument (src/analysis/clade_cumulus.jl:1415–1419). This call therefore raises a MethodError even when the supplied tree has sufficient ASV overlap, preventing both inline and saved-tree UniFrac ordinations. Convert the indexed tree to the supported representation before passing it to the distance helper.

There was a problem hiding this comment.
When model preparation or fitting throws anything other than VeganUnavailable, evaluating this condition raises an UndefVarError because RLockTimeout is not defined. The shared runtime actually throws MetaManifold.RRuntime.RBusyError. This masks both runtime contention and subsequent ArgumentError handling, turning intended 503/400 responses into internal errors; it also prevents the existing busy middleware from receiving the original exception. Match the defined exception type or let that middleware handle it.

Every ordination request that passes formula validation reaches this statement, including non-phylogenetic RDA, CCA, and Bray-Curtis requests, but CladeCumulus is not bound in the Server module. Searching the server and its included routes shows that existing code uses MetaManifold.CladeCumulus or the CC alias defined in routes/cladistics.jl:11, rather than importing that module under its bare name. This statement therefore raises an UndefVarError before fitting or even checking R availability. Qualify these references with MetaManifold or explicitly import the module into the server.

There was a problem hiding this comment.
On an environment with R and vegan installed, r_available() returns true and this condition then throws an UndefVarError instead of entering the statistical accuracy tests. A repository-wide search for vegan_available finds only this call and two benchmark calls, with no implementation. Analysis.r_available() already checks availability by loading vegan in _ensure_r (src/analysis/analysis.jl:1369–1383), so the additional probe is unnecessary. Remove it here and in the benchmark so configured environments can actually execute the live verification.

There was a problem hiding this comment.
When variance partitioning is requested for two predictors plus Condition(...), the supplied adjusted R² values exclude the conditioned component, but pure_varpart_two_way calculates the residual as 1 - adj_r2_ab. Consequently, the fraction labeled “Residuals” includes variance already explained by the conditioning covariates. For the committed microbiome_oral_partial_batch fixture, this produces approximately 0.034587 instead of 0.011792, with the difference being the conditioned adjusted R². Calculate the residual from the combined predictor-and-condition model, or consistently normalize all fractions to the post-conditioning variance.

When the two score axes have different ranges, or the chart is resized, independently autoscaling these axes distorts sample distances and angles between covariate arrows. This undermines the geometric interpretations explicitly offered by the scaling selector: distance interpretation for scaling 1 and correlation interpretation for scaling 2. The shared PlotlyChart component sets a rectangular viewport and permits independent width/height resizing without adding an axis constraint, so neither the interactive plot nor its exported figure preserves this geometry. Set an equal-unit constraint such as yaxis.scaleanchor = "x" with scaleratio = 1 in the generated layout.

When a config PATCH supplies analysis.ordination.permutations: 199.0 or analysis.ordination.scaling: 2.0, these validators accept the values, but _write_config_updates and canonical_yaml_doc preserve them as floating-point numbers. Subsequent ordination requests that inherit those settings pass them unchanged through ordination_config_from_dict into OrdinationConfig, whose corresponding keywords require Integer, causing a TypeError rather than fitting the model. Normalize these accepted whole-number values to Int before storing or constructing the configuration, or reject floating-point values consistently.

bench/constrained_ordination/README.md:24states that the existingAlpha,NMDS, andPERMANOVApaths run "with zero added allocations or runtime regression". The benchmark does not measure this. It times only constrained ordinations and diversity helpers, and it has no baseline comparison. Readers can take the README as evidence that these paths were checked, so the README overstates what the benchmark establishes.📝 Suggested documentation change
-- **Zero overhead on unconstrained diversity paths**: When `analysis.ordination.method` is `"none"` (the default), existing `Alpha`, `NMDS`, and `PERMANOVA` code paths in `MetaManifold.DiversityMetrics` and `MetaManifold.Analysis` execute unchanged with zero added allocations or runtime regression. +- **Unconstrained diversity paths are not benchmarked here**: This harness times only constrained ordinations (`RDA`, `CCA`, `CAP`, `dbRDA`) and diversity helpers.

run_constrained_ordinationtreats ablocksvector whose length differs from the sample count as if no blocks were supplied. The permutation then runs unrestricted, and no error or caution is returned. Every other input length check in the same function throws anArgumentError. Theblockscheck is the only one that falls back silently.Trigger: a direct Julia caller passes a
blocksvector with a repeated individual label but one label missing, so its length isn_samples - 1.Result:
blockedbecomesfalse.ord_blocksbecomes empty. The R permutation uses plainnperm, not apermute::howrestriction. The returned p-values are for an unrestricted design. The output carries no caution, and theuntestable_setis empty.The server route does not reach this path, because its
blocksvector is filtered with the matrix rows. A mismatch needs a direct Julia caller, so the impact is latent.🐛 Suggested fix

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winTest the combined numeric interaction column for block constancy.
_term_untestable_in_blocks(src/analysis/ordination.jl:784-790) tests each part of an interaction term separately. It returns testable when any part varies within a block. It never tests the combineda:bcolumn.For numeric
aandb, thea:bcolumn equalsa * brow by row. Ifbis constant within each block andavaries only in blocks whereb = 0, the column is 0 in everyb = 0block. It is also constant in everyb = 1block. The column is therefore constant within every block, but the helper still returns testable.The p-value assignment keeps R's permutation p-value for every term that is not in
untestable_set(src/analysis/ordination.jl:1165-1171, 1233-1236). Thea:brow therefore keeps its p-value, anduntestable_reasonstays unset. The reason text at src/analysis/ordination.jl:1169-1170 states that a term constant within every block cannot be tested. This report contradicts that rule for this pattern.For interaction terms whose parts are all numeric, test the product column instead:

The accuracy testset title says all four methods match vegan within
1e-6. The comment attest/unit/test_ordination.jl:325says RDA, CCA, CAP and dbRDA are compared directly with vegan. Only dbRDA is fitted in R. The R block fitsvegan::dbrda. Novegan::ccaorvegan::capscalecall appears undertest/orbench/.The CCA and CAP cases check the method label, the scaling value, that CCA conditioned inertia is greater than zero, provenance, the distance, and that the CAP p-value is not
nothing. An incorrect CCA or CAP result that keeps these labels and non-null fields can pass the suite.Remedy:
- Fit CCA and CAP in vegan on the dune data. Compare the numerical outputs that the Julia results expose, such as inertia, eigenvalues, the F statistic, the p-value and site scores, with
atol=1e-6.- Effort: this adds two vegan fits and their comparisons to one testset. The main effort is mapping each Julia result field to its vegan equivalent and checking whether permutation p-values match under the seed. The block runs only where R and vegan are available.
- If a method remains unchecked, correct the testset title and the comment at line 325 instead.
This is a test-coverage gap. The inspected source does not show that CCA or CAP production output is wrong.

Inline comments:
Review comments at @frontend/src/components/ConstrainedOrdinationPanel.tsx:
- Around line 296-317: In the study configuration load effect, clear
loadedStudyCfg.current in the getStudy(study) failure handler when it still
matches the failed study. This lets the next open retry the load without
clearing a newer study’s latch; leave the success path unchanged.
- Around line 332-343: Remove the placeholder `runtimeEst` calculation from
`ConstrainedOrdinationPanel` and show “Runtime estimate unavailable before
submit” in its place, using the muted text colour rather than a warning based on
the placeholder. Keep the Run and Save button behaviour unchanged, and remove
the `estimateOrdinationRuntime` import if it is no longer used.
Review comments at @src/analysis/ordination.jl:
- Around line 398-428: Update the automatic-formula branch in
parse_ordination_formula to skip non-numeric metadata columns whose distinct
labels identify every sample, while retaining numeric columns and other
categorical predictors. Leave explicit-formula handling unchanged.
- Around line 1570-1628: Update the `[d]` row label in the two-term
`Condition(...)` branch to state that residuals include the conditioned share.
Keep `vp2.residual` and the top-level inertia summary unchanged; do not add a
conditioned-only fit.
Review comments at @src/server/routes/ordination.jl:
- Around line 306-314: Update the explicit beta_transform handling in the route
so Aitchison requests reject any non-null value other than “none” with a 400
error; keep the omitted-field default as “none” and preserve existing handling
for other distances.

Minor comments:
Review comments at @bench/constrained_ordination/README.md:
- Line 23: Update the README’s claim about unconstrained diversity paths to
state that this harness benchmarks only constrained ordinations and diversity
helpers, and does not measure Alpha, NMDS, or PERMANOVA or compare their
allocations or runtime before and after changes.
Review comments at @frontend/src/components/ConstrainedOrdinationPanel.tsx:
- Around line 273-278: Update the request and saveStudyDefaults paths to send
null when the formula remains the untouched “~ group” default, allowing the
server to select a formula; preserve explicitly edited formulas. Check the
existing formula validation before changing the default, and ensure validation
still accepts the server-selected fallback.
Review comments at @frontend/src/components/DiversityPanel.tsx:
- Around line 175-182: Update the runs.length < 2 empty-state branch in
DiversityPanel to keep the empty-state message and render
ConstrainedOrdinationPanel when option is available and exactly one run or
sub-group is selected. Preserve the existing behaviour for zero selections and
the run view.
Review comments at @src/analysis/ordination.jl:
- Around line 1210-1233: In `run_constrained_ordination`, validate that any
non-`nothing` `blocks` vector has exactly `n_samples` entries and throw an
`ArgumentError` on mismatch. Then determine `blocked` from whether the valid
vector contains repeated labels, preserving the existing behaviour for `nothing`
and correctly sized vectors.
- Around line 783-800: Update _term_untestable_in_blocks to detect multi-part
interactions whose metadata columns are all numeric, build their row-wise
product, and determine testability from whether that product varies within any
block; leave interactions containing factor columns on the existing path. Add a
regression test for numeric a:b where b is constant within each block and a
varies only where b is zero, asserting untestable_reason is set and p_value is
nothing.
Review comments at @src/core/validate.jl:
- Around line 543-546: Update the ordination check in _validate_pipeline_cfg to
report an error when analysis.ordination is present but is not a mapping, while
continuing to treat null or a missing key as absent and validating mapping
settings as before.

- Around line 179-185: Update the ordination CSV export test to cover quoting in
csvCell: set the mock site sample label to a value containing a comma and assert
that the site_score row contains the quoted label.
Review comments at @test/references/check_ordination_references.py:

matches cannot let an incorrect minimum pass. Validate that min is 99 and max is

comparison in the checker: compare the row counts of stored y and recomputed
y_recomp, then compare each paired row’s column count. Raise an AssertionError
when either dimension differs, while preserving the existing value-drift check

- Around line 788-795: Update the reference-fixture checks in
`verify_fixture_math` and the Julia testset to compare the recomputed
`df_model`, `df_conditioned`, and `df_residual` with their stored `expected_rda`
values. Add the Python comparisons after the eigenvalue loop and matching Julia
assertions after the unconstrained eigenvalue loop.

build_schema_document(), including the expected trailing newline. Raise an
assertion when they differ, while preserving the existing JCS validation.
Review comments at @test/unit/test_ordination.jl:

`res.unconstrained_eigenvalues` and `exp_rda[:unconstrained_eigenvalues]` before
the `zip` loop, matching the constrained spectrum check. Keep the existing
element-wise comparison unchanged.
- Around line 411-413: Narrow the accuracy testset title and its explanatory
comment to describe only methods directly compared with vegan; the current R
reference fit covers dbRDA, not CCA or CAP. Do not imply that the CCA and CAP
checks around run_constrained_ordination validate numerical agreement with
vegan.
- Around line 459-460: In the ordination GET round-trip check, read the response
body after confirming `resp_loaded.status` is 200 and assert that its top-level
`analysis_id` matches the ID returned by the POST (`aid`).

Remove the placeholder runtime estimate, or show it as unavailable.
The pre-submit runtime label uses placeholder inputs. nSamples is Math.max(6, runs.length * 6), which assumes six samples per run. ComparisonRunSpec has no sample count, so the panel cannot know the real study size before submit. For example, two runs of 1,500 samples each show < 1 s. The server formula for n = 3000, 300 features, dbRDA, Bray-Curtis and 999 permutations gives about 887 s.
The > 5 min warning does not fire for realistic run counts. With dbRDA and Bray-Curtis, the placeholder must reach about 1,800 samples before the warning appears. That requires about 300 runs.
The server's runtime_estimate cannot replace the placeholder before submit. The server computes it inside the run request, so the panel cannot show it earlier.
The Run and Save buttons do not depend on this estimate. The change only affects the displayed label.
Suggested fix

- const runtimeEst = useMemo(() => estimateOrdinationRuntime({ - method, - distance, - nSamples: Math.max(6, runs.length * 6), - nFeatures: 300, - permutations: permValid ? permutations : 999, - nTerms: Math.max(1, formulaCheck.constrainedCount), - variancePartitioning, - }), [method, distance, runs.length, permValid, permutations, formulaCheck.constrainedCount, variancePartitioning]) -
- color: runtimeEst.warnFiveMinutes ? 'var(--color-warn)' : 'var(--color-muted-fg)', + color: 'var(--color-muted-fg)',
- Estimated runtime: {runtimeEst.label} - {runtimeEst.warnFiveMinutes ? ' (> 5 min warning: consider fewer permutations for exploration)' : ''} + Runtime estimate unavailable before submit
Remove the
estimateOrdinationRuntimeimport from this file if the panel no longer uses it. I have not read that import line.

Skip per-sample identifiers when building the automatic formula.
When formula is nothing, parse_ordination_formula adds every non-constant metadata column except sample. The route stores individual in metadata. For a single run with one group and no custom covariates, the route leaves the formula unset. If every sample has its own individual ID, individual becomes a categorical predictor with n_samples - 1 degrees of freedom. The saturation check then rejects the model, and the route returns HTTP 400 invalid_ordination_formula. library_size would have been a usable covariate, but the request fails.
A categorical column with one label per sample always saturates the model. Skipping such columns in the automatic branch therefore never removes a valid model. Numeric columns are not affected, and explicit formulas are not changed.

…n unit tests (#260) ## Summary Follow-up test alignment for constrained ordinations (#19 / #258) caught on the full `Julia tests` CI run (`259/265` passing on first run, `0` runtime errors): 1. **`vegan::varpart2` fraction order (`test/unit/test_ordination.jl`, `src/analysis/ordination.jl`)**: `vegan::varpart2` orders `part$indfract` rows with the two testable unique fractions first (`[a] = X1 | X2`, `[c] = X2 | X1`), followed by `[b]` (shared overlap, `0 df`) and `[d] = Residuals`. Aligns `ind[2]` / `ind[3]` in `test_ordination.jl` and the partial-`Condition(...)` two-way `ind_rows` table in `src/analysis/ordination.jl` to that exact ordering. 2. **Pure-Julia `f_statistic` relative tolerance (`test/unit/test_ordination.jl`)**: Adds `rtol=1e-9` alongside `atol=1e-8` when comparing `pure_linear_rda(...).f_statistic` (`F ≈ 820`) against the 12-decimal rounded `ordination_reference.json` fixture (`1.7e-12` relative difference, `1.4e-9` absolute). 3. **Distinct sample names across fixture runs (`test/unit/test_ordination.jl`)**: Uses `c1..c3` and `t1..t3` across `Control/run1` and `Treatment/run2` in `_ord_with_study_root` so independent samples do not inadvertently trigger repeated-measures complete-enumeration warnings.

Two failures inherited from #258 block the required Julia check: - varpart asserted a fixed row order for vegan's $part$indfract. The four documented individual fractions are compared as a multiset of adjusted R2 values now, and the labels are required to be present and distinct, so the test checks the arithmetic rather than an order R does not promise. - f_statistic compared with atol=1e-9 only. On this fixture F is 223 and 820, so that is a relative 1e-12; two correct implementations can differ there by reduction order alone. rtol=1e-9 keeps the same strictness at scale.
