Summary

Composite Bands reported its raster inputs as a plain string in GeoLibre 1.8.0 and 1.8.1, so the existing raster selector was never used. Recognize that legacy metadata in RustGIS so users can select and reorder loaded rasters, with both in-memory and embedded inputs staged in the selected order.

The metadata fallback applies only to that tool's legacy inputs parameter; explicit metadata keeps its usual meaning. Shared GeoLibre staging now also accepts array-valued input lists and rejects explicitly empty or malformed lists instead of dropping them. Optional inputs can still be omitted or cleared with null or an empty string.

Testing

• Regression reproduced on the original code (Text instead of RasterLayers), then passed with the fix.
• String and array input lists preserve staging order and CRS; empty or malformed arrays are rejected.
• Local check with GeoLibre 1.8.1: two output bands retain their values and CRS in both selected orders and input formats. This integration test uses the existing optional-runner setup and is skipped when no runner is installed; the staging regression runs without a runner in CI.
• cargo xtask ci, cargo build --locked --target wasm32-unknown-unknown -p rustgis-web, and all-file publication hooks passed.
• Rendered and inspected the actual Tools form with ui_shot.

UI evidence

Before: live web form using GeoLibre 1.8.0, showing only an Inputs text box.

After: native form using GeoLibre 1.8.1, offering loaded rasters and band-order controls.

Closes #1684.

Summary by CodeRabbit

• Bug Fixes
  • Improved compatibility with legacy composite_bands configurations that omit input-role metadata. Raster inputs now appear in the form and are staged in the requested order.
  • Preserved existing handling for configurations with explicit metadata, including vector inputs.
  • Invalid input lists now report parsing errors instead of being silently treated as empty. Valid input names retain their specified order.

Walkthrough

spec_of now recognizes a specific legacy Composite Bands input parameter as a multi-value raster input. prepare_with parses input names with layer_list and propagates parsing errors. Tests cover parameter classification, staging order, and runner output.

Changes: Legacy Composite Bands raster inputs

Layer / File(s)	Summary
Classify the legacy input crates/geolibre/src/lib.rs, crates/geolibre/src/tests.rs	spec_of treats inputs as a multi-value raster input only when io_role is absent and both data and schema kinds are string. Tests check that other tools retain Text and explicit vector-list metadata resolves to VectorLayers.
Prepare and verify raster inputs crates/geolibre/src/lib.rs, crates/geolibre/src/tests.rs	prepare_with uses layer_list to parse input names while collecting CRS and extent data and staging inputs. Tests check parsing, staging order, output bands, and CRS preservation.

Full details: Linked Issues check

Explanation

Issue #1684 requests a selector or file picker for multiple Composite Bands rasters. spec_of maps the legacy composite_bands.inputs string metadata to a required multi-raster input, which enables the raster selector. Tests verify the form parameter kind and confirm that in-memory and embedded rasters stage in selected order for string and array inputs. The optional runner test also checks output band order and CRS.

Full details: Out of Scope Changes check

Explanation

The shared prepare_with parsing change supports the selector's array-valued layer lists and rejects invalid lists instead of silently dropping them. This change is directly related to selecting and staging multiple rasters. The legacy metadata fallback is limited to composite_bands.inputs; tests confirm other tools' string parameters and explicit metadata retain their existing meanings. The diff shows no unrelated changes.

Bug (confidence: medium): this makes legacy composite_bands.inputs an Input parameter, so it now goes through prepare_with → names (lib.rs ~589–591). names only reads Value::String, so an array value such as ["dem", "embedded"] is dropped with no notice. value_of passes arrays through, and rustgis_analysis::layer_list documents arrays as a supported layer-list format. Nothing on the geolibre path (params_for only normalizes built-in tools) turns an array into ;-joined text. The result is either a runner error for a missing required input (the wrong message) or a silent run with no inputs. Other many-input GeoLibre tools already have this gap; this PR routes Composite Bands into it.

Suggested fix: make names accept arrays too, e.g.

let names = |v: &Value| -> Vec<String> {
    let items: Vec<&str> = match v {
        Value::String(s) => s.split(';').collect(),
        Value::Array(a) => a.iter().filter_map(Value::as_str).collect(),
        _ => Vec::new(),
    };
    items.into_iter().map(str::trim).filter(|n| !n.is_empty()).map(str::to_string).collect()
};

Non-string array items would still be skipped silently. If you want them refused, return a Result and use ? at the call in prepare_with. A regression test beside composite_bands_legacy_manifest_selects_and_stages_rasters_in_order would pin it: {"inputs": ["embedded", "dem"]} should stage in the same order as "embedded;dem".

[Mavrick-F]

Reproduced and fixed in f5be4c6a. Preparation now uses the shared layer-list parser for CRS selection and file staging. The regressions cover strings and arrays in both orders, plus rejection of malformed arrays. GeoLibre 1.8.1 output-band checks, full CI, wasm and hooks passed.

Code review

Bugs

• Array-valued inputs is dropped silently (confidence: medium). This PR makes legacy composite_bands.inputs an Input parameter, so it now goes through names in prepare_with (crates/geolibre/src/lib.rs ~589–591). That closure only reads strings. layer_list accepts arrays, and nothing on the geolibre path converts them, so ["dem", "embedded"] produces no --inputs argument. The run then fails with the wrong error or runs with no inputs. Posted inline at lib.rs:245 with a suggested fix and a regression test idea. Other many-input GeoLibre tools already have this gap, but this PR routes Composite Bands into it.

Security

• None found.

Performance

• None found.

Quality

• Runner-dependent tests never run in CI (confidence: high that they are skipped; low impact). composite_bands_runner_preserves_selected_band_order and manifests_become_tool_forms return early without a GeoLibre runner, and no workflow under .github/ installs one. The end-to-end band-order result therefore rests on the author's manual run. The prepare-level test composite_bands_legacy_manifest_selects_and_stages_rasters_in_order does cover staging order in CI. Not posted inline; this is the existing test convention.

AGENTS.md

• No violations found. Non-test code has no unwrap/expect/panic, and the new long lines are within max_width = 140. There are no new user-visible strings, no new dependencies, and no new background work. Staging goes through the existing prepare_with path.

Behaviour change beyond Composite Bands (confidence: high that it changes; medium that it matters). names now calls rustgis_analysis::layer_list for every Input-role list in every GeoLibre tool, not just legacy composite_bands.inputs. Three effects:

• Array values are now accepted for all such tools. Previously they were silently dropped, so this fixes a silent loss, but it is still a change.
• Non-string, non-array values (for example a number) now error. Previously they were skipped.
• An explicit empty array [] (or a whitespace-only string) for an optional input now fails with "at least one input layer is required". Previously it was skipped. Only API callers can send []: the form sends ;-joined text and clears to "", which value_of still filters.

The PR description says "other tools retain their current behavior", which is not accurate. Please either correct that sentence or add a test that pins the other-tool behaviour (an optional many-input given [] and given an array). I did not find a crash path.

[Mavrick-F]

Corrected the PR description. The metadata fallback is specific to Composite Bands; the shared staging parser now accepts arrays and explicitly rejects empty or malformed lists for GeoLibre inputs. Optional values can still be omitted or cleared with null or an empty string. This avoids the previous silent drops. No source change was needed.

[github-actions]

Test coverage (confidence: high). setup() returns None when no GeoLibre runner is installed, and this test then returns early after an eprintln!. In a CI job without the runner it passes without checking anything. The unit test composite_bands_legacy_manifest_selects_and_stages_rasters_in_order does cover the ordering without a runner, so the regression itself is guarded. The runner test is only the end-to-end check the PR description cites. Please say in the PR which CI job runs it with a runner, or note that it is local-only, so the claim is not read as CI coverage.

[Mavrick-F]

Clarified the Testing section: the GeoLibre 1.8.1 output-band check was run locally. It follows the existing optional-runner convention; the staging and input-validation regression runs without a runner in CI.

[Mavrick-F]

The array-input bug is fixed in f5be4c6a, with string/array order regressions and passing full CI, wasm and hooks.

The runner integration follows the existing optional-runner setup and was exercised locally with GeoLibre 1.8.1. Mandatory tests cover staging in both formats and orders. Installing the runner in CI and adding documentation to the named regression tests are left for the release quality pass; both changed non-test functions are documented.

Code review

Bugs

• Behaviour change beyond Composite Bands (crates/geolibre/src/lib.rs:590). Every Input-role list in every GeoLibre tool now goes through layer_list. Array values are now accepted (a silent-drop fix). Non-string values now error. An explicit [] for an optional input now fails with "at least one input layer is required", where it was skipped before. The PR body says other tools "retain their current behavior", which is not accurate. Confidence: high that it changes, medium that it matters. Inline comment posted.
• The prior thread's concern (array values silently dropped by names) is fixed at this head. layer_list accepts arrays and rejects malformed entries. I did not re-post it, and the thread is still open.

Security

• None found.

Performance

• None found.

Quality

• Nothing that needs a fix in this PR. The composite_inputs predicate and the Role/ParamKind mapping read correctly.

AGENTS.md

• Never silent: the array and malformed-input paths now report errors instead of dropping entries. This is compliant.
• Never crash: no new unwrap/expect/panic in non-test code. Tests use panic! and unwrap, which is allowed there.

Test coverage

• crates/geolibre/src/tests.rs:183: composite_bands_runner_preserves_selected_band_order returns early when no GeoLibre runner is installed, so in CI without one it passes vacuously. The unit test composite_bands_legacy_manifest_selects_and_stages_rasters_in_order covers the ordering without a runner. Confidence: high. Inline comment posted.
• No test covers the new RasterLayers kind for legacy composite_bands on the engine side (crates/engine/src/model.rs:67, policy/plan.rs:763–799). It now becomes a multi-raster port and a recorded layer read. Those effects are probably intended, but nothing pins them. Confidence: low–medium.

Verified by reading

• The /work argv assertion is safe on Windows: the separator is chosen from the dir string, which has no backslash.
• Band.data is Vec<f32>, so the exact-equality checks on 14.3 survive the GeoTIFF round trip.
• The ParamKind::RasterLayers form path (panes.rs:3066) emits ;-joined text, so the form itself is unaffected.

Already raised (left alone): 1 earlier thread (crates/geolibre/src/lib.rs line 245, array-value drop). It is addressed at this head, so I did not re-post it.

[Mavrick-F]

The description now states the shared staging behavior and identifies the GeoLibre runner check as local coverage. Engine model ports and read planning intentionally consume the same RasterLayers metadata; additional tests of those existing consumers are left for the release quality pass.
