Summary

Open a GeoLibre .geolibre or legacy .geolibre.json project as a new map, preserving the current project and its unsaved work. Adds project.importGeolibre with file, URL, JSON text and base64 inputs; desktop Open/Project New/drop routing; and browser project links and asynchronous source loading. Imports supported sources, view, bookmarks, groups, visibility, colour classes and labels, with per-layer notes for differences and skipped content.

GeoLibre JSON → bounded map parser → existing source commands → new map
                                              browser downloads → reserved layer completion

Combined classified colour and proportional size is tracked separately in #1017. This importer retains classified colour and reports fixed size for combined styles. Single-style proportional symbols remain supported. Browser imports refuse batches that exceed the available 16 whole-file download slots before creating a map; streaming tiles/COGs use no slots. The renderer extension and saved-project representation will be designed in that follow-up; this PR adds no renderer/schema fields or dependencies.

Testing

• Before: RustGIS could not open GeoLibre projects; after: hand-authored parser/source/style fixtures, hostile command parameters and real app-frame picker/drop tests cover the new entry points.
• Final tree, including integration with upstream main at 58e0d34: cargo xtask ci passed (fmt, workspace Clippy with -D warnings, workspace tests and layers), cargo build --locked --target wasm32-unknown-unknown -p rustgis-web passed, and pre-commit run --all-files passed. Both app-frame Zarr regressions passed in a focused run as well. Subsequent regressions cover serialized/budgeted Zarr reads, saved native slice indices and 1,000-group ancestry. Further tests cover consecutive-import admission, extensionless COGs, native plain-TIFF fallback opacity and engine/assistant callback guards.
• Review fixes: Zarr completion regression now advances the app frame; rejecting a seventeenth concurrent browser Zarr store removes its reserved layer and group reference, including after a map switch.
• Manually imported GeoLibre's hosted earthquake demo (1,974 earthquakes and 241 plate-boundary features), waited for the basemap, saved .rgis, reopened it and compared screenshots. View and colour class boundaries persist; combined size remains the documented limitation tracked in Support proportional size alongside classified point colours #1017. Screenshots are retained privately, not committed.

Summary by CodeRabbit

• New Features
  • Import supported GeoLibre projects as new maps from .geolibre or .geolibre.json files, web links, text, or base64 data.
  • Restore supported layers, styles, groups, bookmarks, and map settings. Import notes identify content or appearance that could not be fully preserved.
  • Open GeoLibre projects from the Start page, file picker, Command Search, or supported web links.
  • Import supported Zarr sources as map layers.
  • Browser imports may be limited when many whole-file downloads are required; oversized batches are refused before a map is created.
  • Saving projects and recovery copies is unavailable while imported layers are still downloading.
• Documentation
  • Added guidance on importing GeoLibre projects, supported content, and browser download limits.

Walkthrough

GeoLibre project files can now be imported as new maps through engine commands, desktop and web entry points, and project links. The importer parses project data, applies supported styles and map settings, reports unsupported content, and handles remote layers and Zarr sources.

Changes: GeoLibre project import

Layer / File(s)	Summary
Project parsing and style translation crates/map/src/geolibre.rs, crates/map/src/geolibre/style.rs, crates/map/src/lib.rs	The map crate validates GeoLibre JSON, converts camera and layer settings, and applies supported renderers, symbols, and labels. Import reports identify unsupported or approximated settings. Tests cover parsing, limits, ordering, and style behavior.
Engine import and map state crates/engine/src/cmd/geolibre.rs, crates/engine/src/cmd/layer.rs, crates/engine/src/cmd/mod.rs, crates/engine/src/cmd/plugins.rs, crates/engine/src/lib.rs, crates/engine/src/project.rs, crates/engine/src/tests.rs, crates/assistant/src/tools.rs, crates/assistant/src/tests.rs	project.importGeolibre accepts project input, adds a map, imports supported sources, and restores groups, layer order, camera, and bookmarks. It tracks pending remote layers and removes reservations after failures. Project opening routes GeoLibre files to the command. Tests cover input errors, source handling, and map state. The command is reserved for user execution, and approval checks cover related download calls.
Browser layer and Zarr downloads crates/ui-egui/src/geolibreui.rs, crates/ui-egui/src/lib.rs	The UI polls asynchronous GeoLibre Zarr reads and sends completed data to reserved layer positions. Failed reads and downloads discard pending import state. Tests cover completion after map switching and cleanup when reads fail to start.
Project import entry points and documentation apps/rustgis-web/src/web.rs, crates/ui-egui/src/backstage.rs, crates/ui-egui/src/chrome.rs, crates/ui-egui/src/lib.rs, crates/ui-egui/tests/geolibre_projects.rs, docs/comparison/geolibre.md, docs/user-guide/workspace.md, ROADMAP.md	The web and desktop interfaces recognize GeoLibre project extensions. The Start page and Command Search route to the import flow. Tests cover picker and filename handling. Documentation describes supported inputs, imported content, and limitations.

Merge Risk: Moderate · up to bab29

Prevent packaging unfinished imports before merging: reopened packages can contain empty layers that never finish downloading and block subsequent saves. Browser MBTiles downloads can also silently revert visibility and opacity edits made while waiting.

Bug (medium-high confidence): "json" was added to this Open picker's filter, but only .geolibre/.geolibre.json are routed to the importer. Any other .json the user picks (for example a plain GeoJSON file) falls through to project.open, which fails with a project-parse error. Before this PR a .json could not be picked here.

project::open_command already sends non-project files to layer.addData, so the fallback can reuse it:

Suggested change

	let cmd = if lower.ends_with(".geolibre") || lower.ends_with(".geolibre.json") {
	let cmd = if lower.ends_with(".qgs") || lower.ends_with(".qgz") { "project.importQgis" } else { rustgis_engine::project::open_command(&path) };

[Mavrick-F]

Fixed in c49df6e. The desktop picker now uses open_command for its fallback, so plain JSON goes to the data reader; QGIS routing remains explicit. Focused regressions, full workspace CI, wasm build and hooks passed.

[github-actions]

Bug (low-medium confidence): layers without a groupId are keyed under "" in groups. A group record with no id gives string(g, "id") == "", so groups.remove("") pulls every ungrouped layer into that malformed folder. Skip the empty id:

Suggested change

	group.children = groups.remove(string(g, "id")).unwrap_or_default();
	group.children = if string(g, "id").is_empty() { Vec::new() } else { groups.remove(string(g, "id")).unwrap_or_default() };

[Mavrick-F]

Fixed in c49df6e. An empty group id no longer collects ungrouped layers. Added a regression with a hidden malformed folder. Focused regressions, full workspace CI, wasm build and hooks passed.

[github-actions]

Quality (low): finish_layer gives the replacement layer the placeholder's id (loaded.id = target.1), but finish_archive does not. The completed tile keeps a fresh id, so later lookups by the pending token (discard_pending, finish_archive's own position) no longer find it. Mirror the layer path:

Suggested change

	*t = loaded;
	loaded.id = token.to_string();
	*t = loaded;

[Mavrick-F]

The token identifies an unfinished archive reservation. After successful replacement the tile is complete and should no longer match discard_pending or a duplicate completion. Unlike feature layer ids used in folder membership, this transient token need not survive completion; retaining it would let a late failure discard a completed tile.

[github-actions]

Code review

Bugs

• Desktop Open picker routes any non-GeoLibre .json to project.open, which fails. "json" was added to the filter in crates/ui-egui/src/lib.rs:2497, but only .geolibre and .geolibre.json are routed to the importer. Suggested fix: reuse project::open_command as the fallback. Inline comment posted. Confidence: medium-high.
• A group record with no id adopts every ungrouped layer. Ungrouped layers are keyed under "", and groups.remove("") pulls them into the malformed folder (crates/engine/src/cmd/geolibre.rs:136). Inline comment posted with a fix. Confidence: low-medium.

Security

• Opening a project reads any existing absolute path and any ..-relative path the project names, then loads that data into the map, where it can be saved into .rgis. This follows the QGIS importer's pattern, so it is a design question rather than a regression. Confidence: low-medium.
• Internal keys (geolibreProject, geolibreLayer, geolibreZarr) are accepted on public commands (layer.addDownload, ui.addUrl). Those commands can reach the importer without the project.importGeolibre plugin gate. Impact is limited because a download id must already exist. Consider rejecting these keys from external callers. Confidence: low.

Performance

• On native builds, project.importGeolibre with a url, and MBTiles layers, call blocking downloads with a 60 s timeout on the thread that runs the command. Desktop callers may stall the UI. Confidence: low.

Quality

• finish_archive does not carry the placeholder's token onto the replaced tile, unlike finish_layer. Inline comment posted at crates/engine/src/cmd/geolibre.rs:437. Confidence: medium.
• Test code is not rustfmt-style (for example let text=json!( at crates/engine/src/tests.rs:17979). If CI runs cargo fmt --check, this will fail. Confidence: medium.
• add_layer is about 150 lines with a six-step fallback chain for the address. A helper would make it easier to read.
• The basemap sets visibility on tiles.last_mut() rather than the index the command returns. It works only because the map is fresh.
• download_url and is_project_file have no direct unit tests, and the finish_archive path is untested.

AGENTS.md

• Compliant on panics and unwrap, unsafe, layering, wasm gating, the plugin NEVER list, and tl! in UI strings. No new dependencies.
• apps/rustgis-web/src/web.rs adds an untranslated filter label. The old label was also untranslated, so this is a nit.

Performance (confidence: medium, severity: low). s.project.clone() runs once per layer, so a project with N layers clones every map and layer N times. Features are Arc-shared, so the cost is shallow, but it still grows as O(N × model size). Snapshotting once before the loop, or rolling back only the ids added by the failing layer, avoids the repeated clone.

[Mavrick-F]

Keeping the per-layer snapshot for transactional rollback. The parser caps imports at 1,000 layers and Dataset features are Arc-shared. A single pre-loop snapshot would discard earlier successful imports on a later failure; rolling back only new ids would miss mutations to other project state. This low-severity optimization does not justify weakening rollback here.

[github-actions]

Bug (confidence: medium). When add_named_bytes has already added layers and this check fails, the error returns without removing them. discard_pending only removes layers whose source is the reservation token, so the extra layers stay in the target map. This is reachable when a multi-layer URL source is downloaded. Record the pre-existing ids and remove any new layers before returning the error, as the import_project error path already does with s.project = before.

[Mavrick-F]

The public layer.addDownload command is mutating and executes through Session::guarded, which snapshots the Project and restores it on Err. The multi-layer check therefore rolls back the added layers before UI discard_pending removes the reservation. The helper itself is not the transaction boundary.

[github-actions]

Bug (confidence: high, impact low). split(['?', '#']) is meant for URLs, but open_command calls this function with local paths. A file such as plan#2.geolibre is cut to plan and is not recognised, so the CLI and drag-and-drop route it to layer.addData. Callers already strip the query (project_file_name), and ui.openUrl passes full URLs that would need it. Move the stripping to those URL callers and keep this check a plain suffix test:

Suggested change

	name.ends_with(".geolibre") || name.ends_with(".geolibre.json")
	let name = name.to_ascii_lowercase();

[Mavrick-F]

Fixed in c49df6e. Query/fragment stripping now applies only to web URLs. Local names containing # or ? retain their suffix; unit and drop-path regressions cover both. Focused regressions, full workspace CI, wasm build and hooks passed.

[github-actions]

Security (confidence: medium, depends on threat model). resolve reads whatever a project names. An absolute sourcePath that exists is used directly, and a relative one is joined onto dir without checking for ... A shared .geolibre from a URL can therefore pull in local CSV, GeoJSON or other data (for example ../../secret.csv) into the attribute table and notes. Consider rejecting .. components in relative paths, and listing the resolved path in the import notes so the user can see what was read. Absolute paths may be an intentional move-friendly fallback, so that is a design call.

[Mavrick-F]

Retaining the explicit sourcePath contract from #962: existing absolute paths are read, with moved-file fallback under dir. This is a user-only file/network import, gated for assistant execution and excluded from plugins, consistent with QGIS import. Importing intentionally reads referenced datasets; it does not send their contents to a remote service. Folder confinement would change that contract, so no new confinement policy is introduced here.

[github-actions]

Bug (confidence: medium). The picker now lists json, so a plain .json file (for example GeoJSON) falls into this else and runs project.open, which fails with an unhelpful error. .json is not a RustGIS project extension, so route it to project.importGeolibre. That gives a clear "not a GeoLibre project" error for other JSON files:

Suggested change

	"project.open"
	} else if lower.ends_with(".qgs") || lower.ends_with(".qgz") {
	"project.importQgis"
	} else if lower.ends_with(".json") {
	"project.importGeolibre"
	} else {
	"project.open"
	};

[Mavrick-F]

Fixed in c49df6e. The desktop picker now uses open_command for its fallback, so plain JSON goes to the data reader; QGIS routing remains explicit. Focused regressions, full workspace CI, wasm build and hooks passed.

Code review

Bugs

• finish_layer leaves stray layers in the target map when add_named_bytes added layers but the ids.len() != 1 check fails. Only the placeholder is discarded. Confidence: medium. Inline (crates/engine/src/cmd/geolibre.rs:380).
• The browser ?project=/.json picker routing: a plain .json from the picker goes to project.open, which fails with an unhelpful error. Confidence: medium. Inline (crates/ui-egui/src/lib.rs:2523).
• is_project_file strips ? and # from local paths, so plan#2.geolibre is not recognised by the CLI or drag-and-drop. Confidence: high, impact low. Inline (crates/map/src/geolibre.rs:150).

Security

• resolve reads whatever the project names: absolute paths that exist are used directly, and relative paths are joined onto dir without rejecting ... A shared project can pull local CSV or GeoJSON into the attribute table and notes. Confidence: medium, depends on threat model. Inline (crates/engine/src/cmd/geolibre.rs:344).
• No leaked secrets or unsafe input handling found. Reads are capped at 64 MiB, and download_blocking is size-capped.

Performance

• s.project.clone() runs once per layer, so cost grows with layers × model size. Features are Arc-shared, so the impact is modest. Confidence: medium, severity low. Inline (crates/engine/src/cmd/geolibre.rs:114).

Quality

• Nit: the layer address fallback chain in add_layer (geolibre.rs around lines 237–246) repeats the same tiles/url/data lookups three times. A small helper would read better.
• Nit: layers.sort_by_key with position is O(n²) over up to 1000 layers. This is negligible here.
• Nit: the geolibre_moved_local_source_uses_project_directory test deletes its temp directory only on success, so a failed assertion leaks it.
• Nit: the backstage.rs card() change to ui.is_enabled() is a drive-by accessibility change that the PR description does not mention.

AGENTS.md

• No unwrap/expect/unsafe in non-test code. Crate-level deny and the plugin NEVER list are respected.
• project.importGeolibre is gated for the assistant and excluded from plugins.
• The wasm std::time and web_time usage is correct.
• Confirmed by reading: download_blocking is capped at MAX_DOWNLOAD, and the web ?project= link receives the rewritten .geolibre.json URL, so it resolves correctly.
• I did not build or run the tests. I reviewed by reading only.

@coderabbitai full review

Please review this draft explicitly; automatic review was skipped because it is a draft. The current head includes the Zarr app-frame completion and failed-reservation cleanup fixes, integration with main, and passing CI/wasm/hooks.

The draft remains pending a maintainer scope decision: whether to extend classified renderers with an independent optional size mapping here or separately. Combined classified colour and proportional size is explicitly unfinished; the proposed extension is described in the PR body and has not been implemented.

Bug (medium confidence): transparency is applied twice when a stop has no usable colour. symbol.fill already has fillOpacity in its alpha. When the stop's colour is missing or not hex (for example rgb(...)), color() returns that already-faded fill as the default, and painted() multiplies its alpha by the fill alpha again. With fillOpacity 0.6 (alpha 153), the class ends up at 153·153/255 ≈ 91. Same issue on line 69 for graduated. Fix: use an opaque default so painted() applies the fill opacity once.

Suggested change

	(value, painted(symbol, color(stop, "color", symbol.fill, report, &name), layer.geometry_type()))
	(value, painted(symbol, color(stop, "color", symbol.fill.with_alpha(255), report, &name), layer.geometry_type()))

[Mavrick-F]

Fixed in c49df6e. Class colours now use the original unscaled fill as fallback and apply fillOpacity exactly once. Regressions cover categorized/graduated classes with missing, unsupported and translucent colours. Focused regressions, full workspace CI, wasm build and hooks passed.

[github-actions]

Bug (medium-high confidence): a plain .json chosen in this picker is sent to project.open. The json filter was added at line 2513, but the routing only maps .geolibre/.geolibre.json to the importer. Any other .json, including a non-GeoLibre file or a .json GeoLibre export, falls through to project.open and fails with a RustGIS-project error. Fix: route any .json here to project.importGeolibre, so the importer reports a clear "requires name, version and mapView" error.

Suggested change

	"project.open"
	} else if lower.ends_with(".json") {
	"project.importGeolibre"
	} else {
	"project.open"

[Mavrick-F]

Fixed in c49df6e. The desktop picker now uses open_command for its fallback, so plain JSON goes to the data reader; QGIS routing remains explicit. Focused regressions, full workspace CI, wasm build and hooks passed.

[github-actions]

Bug (medium confidence): local paths containing ? or # are misrouted. open_command calls this function on local file paths, but it splits on ?/# as if they were URL query markers. plan#2.geolibre becomes plan and goes to layer.addData. Keep the query stripping for URLs only, and test the raw file name for local paths.

[Mavrick-F]

Fixed in c49df6e. Query/fragment stripping now applies only to web URLs. Local names containing # or ? retain their suffix; unit and drop-path regressions cover both. Focused regressions, full workspace CI, wasm build and hooks passed.

[github-actions]

Security (medium-low confidence; the user opens the file, but the project chooses the path). A project can name any absolute path that exists, or a .. relative path, and the importer reads it into a layer. The attribute table then shows the contents, and a remote source is fetched automatically when the project opens. The import is user-initiated, so this is more an information-exposure and privacy concern than code execution. Consider confining relative paths to the project folder (reject .. components) and calling out, in the import notes, absolute paths and remote hosts the project names.

[Mavrick-F]

Retaining the explicit sourcePath contract from #962: existing absolute paths are read, with moved-file fallback under dir. This is a user-only file/network import, gated for assistant execution and excluded from plugins, consistent with QGIS import. Importing intentionally reads referenced datasets; it does not send their contents to a remote service. Folder confinement would change that contract, so no new confinement policy is introduced here.

[github-actions]

Bug (high confidence): zoom limits are inverted. Layer::min_scale is the "out beyond" limit (layer.scaleRange docs: "min": scale (out beyond)), and sharing.rs::zoom_range maps it to minzoom. Here maxZoom goes to min_scale and minZoom goes to max_scale, so a layer with minZoom: 10 disappears when zoomed in past 10 and a maxZoom: 14 layer is only drawn when zoomed in past 14. No test covers the mapping, which is why this passed.

Suggested change

	layer.min_scale = scale(st, "maxZoom", 24.0);
	layer.max_scale = scale(st, "minZoom", 0.0);
	layer.min_scale = scale(st, "minZoom", 0.0);
	layer.max_scale = scale(st, "maxZoom", 24.0);

The same swap is on the label lines (135–136). A regression test should check that minZoom: 10 yields min_scale == scale(10).

[Mavrick-F]

Fixed in c49df6e. minZoom now maps to min_scale and maxZoom to max_scale for layers and labels. A regression checks zooms 1, 3, 5, 10 and 15 against the 3–10 interval. Focused regressions, full workspace CI, wasm build and hooks passed.

[github-actions]

Bug (high confidence): same inversion for label zoom limits. maxZoom must go to max_scale and minZoom to min_scale.

Suggested change

	c.min_scale = scale(labels, "maxZoom", 24.0);
	c.max_scale = scale(labels, "minZoom", 0.0);
	c.min_scale = scale(labels, "minZoom", 0.0);
	c.max_scale = scale(labels, "maxZoom", 24.0);

[Mavrick-F]

Fixed in c49df6e. minZoom now maps to min_scale and maxZoom to max_scale for layers and labels. A regression checks zooms 1, 3, 5, 10 and 15 against the 3–10 interval. Focused regressions, full workspace CI, wasm build and hooks passed.

[github-actions]

Bug (medium-high confidence): COG and TIFF raster layers in a folder get the folder's opacity and visibility twice. The tile predicate also matches cog/raster TIFF URLs, which are ordinary raster layers, not tile overlays. The code bakes own × group opacity into the record here, and LayerGroup transparency is then applied again at render time (map/src/lib.rs:840 says group opacity applies "on top of each child's own"). A 50% folder over a 100% COG therefore draws at 25%. Only real tile kinds (which can't join a folder) should bake. Feature and raster layers should keep their own values and let the folder apply.

[Mavrick-F]

Remote COG/TIFF sources are tile-stack entries here: layer::add_cog calls tiles::add and returns an index; the importer handles that as Ok(None), so it does not add a feature-layer id to the folder. Folder settings are baked once because tile entries cannot belong to LayerGroup. Local raster feature layers instead use their own settings and folder opacity. Removing this predicate would lose remote COG folder settings.

[github-actions]

Code review

Six inline comments are posted. The most serious is that the zoom limits are inverted.

Bugs

• Zoom limits inverted (high confidence). style.rs:13-14 and :135-136 map maxZoom to min_scale and minZoom to max_scale. In RustGIS min_scale is the "out beyond" limit, which zoom_range maps to minzoom. Layers and labels disappear at the wrong zooms, and no test covers the mapping.
• COG and TIFF layers in folders get opacity applied twice (medium-high). cmd/geolibre.rs:106-109 bakes folder opacity into raster layers that are not tiles. The folder's transparency is then applied again at render time, so a 50% folder over a 100% COG draws at 25%.
• Plain .json opened from the desktop picker goes to project.open (medium-high). ui-egui/src/lib.rs:2523. The json filter was added, but only .geolibre and .geolibre.json are routed to the importer.
• Alpha squared for stops with no usable colour (medium). style.rs:44 (and :69 for graduated). When a stop's colour is missing or not hex, painted() applies the fill opacity a second time (for example, 153 becomes 91).
• Local paths with ? or # are misrouted (medium). map/src/geolibre.rs:148. is_project_file strips query text from local file names, so plan#2.geolibre goes to layer.addData.

Security

• Project-named paths are read and remote sources are fetched on open (medium-low). engine/src/cmd/geolibre.rs:338. Absolute and .. paths that exist are read into layers. The user opens the file, so this is mainly an exposure and privacy concern. Consider confining relative paths to the project folder and noting absolute paths and remote hosts in the import notes.
• Internal keys bypass the plugin gate (low confidence, not commented). geolibreProject and geolibreLayer are accepted by layer.addDownload, which is not on the NEVER list. A plugin that obtained a download id could import a project through it.

Performance

• None significant. Project::clone per layer is cheap because features are copy-on-write.

Quality

• The address fallback chain in add_layer reassigns address five times, and two of the fallbacks are redundant.
• The card doc comment lost its description, and card is now used for non-project cards too.
• Nit: the web picker label "Projects (RustGIS, GeoLibre)" in web.rs is not wrapped in tl!, unlike the desktop one.

AGENTS.md

• No unwrap or expect in non-test code, unsafe is not used, and the wasm paths use web_time.
• Every new command is in the plugin NEVER list and the assistant gate.
• Dependencies used by the new code (base64, rusqlite, web-time, egui_kittest) are already in the workspace, so no Cargo.toml changes are needed.
• Gap: no test covers the scale-range mapping or the folder-opacity case above. Add regression tests with the fixes.

Bug (browser, ~75% confidence): the import queues every remote layer in one command, and Session::request_url refuses past MAX_URL_REQUESTS (16, crates/engine/src/lib.rs:647). In the browser, layer 17 onward fails with "16 downloads are already waiting", is rolled back here, and is only listed in the notes. A GeoLibre project with more than 16 remote layers therefore loses the rest, and re-importing creates a second map. The cap should not apply to the reservations one import makes, or the import should refuse up front with a clear message that says so.

[Mavrick-F]

Fixed in 51504cc. The browser now checks required whole-file download slots before map.new and refuses an oversized batch atomically with an explicit message. Existing queued downloads reduce the available slots; streaming tiles/COGs and inline features use none. Shared source-address/inline resolution keeps the check consistent with loading. Regressions cover 17/16/15 requests and source-kind exceptions. Focused tests, full CI, wasm and hooks passed.

[github-actions]

Performance (desktop, ~60% confidence): on native, project.importGeolibre runs on the UI frame, and layer.addUrl for each remote layer blocks on download_blocking, which waits up to 60 s per layer (BLOCKING_TIMEOUT). A project with several remote layers freezes the window for the sum of those downloads. If project.importQgis has the same shape, this is pre-existing and can be a follow-up. Otherwise, consider fetching through the background download path, as ui.addUrl does.

[Mavrick-F]

Confirmed: native URL import uses the existing synchronous layer.addUrl contract, so slow sources can delay completion. Moving native command execution onto asynchronous UI state is a separate lifecycle change; this PR retains native command/CLI semantics. The user guide now documents synchronous desktop imports in the pending follow-up batch.

[github-actions]

Nit (quality): _folder is underscore-prefixed but is read in the wasm branch (_folder.0, _folder.1). Rename it to folder and drop the underscore so the signature matches its use; in the native build it can carry #[cfg_attr(not(target_arch = "wasm32"), allow(unused_variables))] or be used explicitly.

[Mavrick-F]

The underscore is intentional: this parameter is unused in the native configuration and read only in the wasm branch, where pending MBTiles metadata needs the effective folder look. The prefix avoids suppressing unused-variable warnings on native builds; using an underscore-prefixed binding in another configuration is valid Rust. No behaviour change is needed.

[github-actions]

Low (bug, confidence ~70%): the "drawn differently" count is built from approximated notes keyed by layer name, so two layers with the same name collapse to one, and it also counts layers that only say "downloading; style applied later". Consider counting layer indices or distinct record ids, and separating "downloading" from "drawn differently" in the message.

[Mavrick-F]

Fixed in 73d5bad. The summary counts successful completed records, independently of layer names. Pending downloads and skipped records do not contribute to drawn-differently. Per-record reports are merged through Report::note to retain deduplication/occurrence counts. Regressions cover two tile records with the same name and a skipped record with a parser approximation note. Focused regressions, full CI, wasm and hooks passed.

[github-actions]

Possible leftover state (correctness, confidence ~45%): on this error path finish_layer restores the camera and active map but not the project. If add_named_bytes added a layer and the ids.len() != 1 check fails, that layer stays in the target map. import_project avoids this by snapshotting and restoring s.project on error; a similar snapshot/restore here would make the failure path atomic.

[Mavrick-F]

The public layer.addDownload command executes through Session::guarded (engine/src/lib.rs). It snapshots the Project for mutating commands and restores it on Err before the UI calls discard_pending. finish_layer is a helper within that transaction, not the transaction boundary. A failed single-layer check therefore restores the added layers and active map; an extra full-project snapshot here would duplicate the existing rollback.

[github-actions]

Code review

Bugs

• finish_layer (crates/engine/src/cmd/geolibre.rs, ~line 443): if the downloaded file adds a layer and then the single-layer check fails, that layer stays in the target map, because only camera and active map are restored. Confidence ~45%. Inline comment posted.
• The "drawn differently" count in the import notice (geolibre.rs, ~line 151) is keyed by layer name, so duplicate names collapse, and "downloading" notes are counted as differences. Confidence ~70%. Inline comment posted.

Security

• The assistant approval gate for ui.addUrl (crates/assistant/src/tools.rs, line 184) checks only geolibreProject. geolibreLayer and geolibreZarr reach the same UI path unchecked, and ui.addUrl is not in NEVER. Impact looks low, since tokens must match a pending placeholder and the Zarr path is a normal download. Confidence ~60%. Inline comment posted with a suggested fix.
• Relative data paths in resolve() can climb out of the project folder with ... This is user-approved input, so the risk is low. Not commented.

Performance

• Nothing significant. import_project clones the project per layer, which is cheap because features are shared. Group ancestry and ID lookups are bounded.

Quality

• add_layer takes _folder but reads it in the wasm branch. Rename it to folder. Inline comment posted.
• The new Zarr reader, geolibreui.rs, is well bounded and its tests cover the budget and map-switch cases.

AGENTS.md

• The PR changes path handling (Windows separators, C:/ paths) and file-picker filters. AGENTS.md asks for a ci:windows or ci:macos label for that kind of change, and the PR does not mention one.
• The start page gains a visible card, but the PR says screenshots are kept privately and not attached. AGENTS.md asks for screenshots on substantial visible changes.
• Panic rules hold in the new non-test code. Indexing uses get, and unwrap appears only in test modules. Wasm-specific code is cfg-gated. No new dependencies are added.

I checked the remaining areas (wasm admission counting, request_only handling, Zarr budget, undo, and ui.openUrl limits) by reading, and found nothing else worth raising.

[Mavrick-F]

Pushed 73d5bad: all internal UI callback keys now require importer approval, and the import summary counts completed records instead of note names. Focused regressions, full local CI, wasm and all hooks passed (28m39s under the default host profile). The rollback and cfg-only parameter comments are answered inline with the existing transaction boundary/build configuration. No local code changes remain pending; waiting for GitHub checks and review of this head.

[github-actions]

Performance: this deep-clones the whole Project for every layer record. The project grows with each imported layer (its features are already in it), so importing N layers copies roughly N²/2 layers' worth of data. The snapshot only exists to roll back one failed record.

Suggest snapshotting once and rolling back by id: record the layer and tile ids before add_layer (the before set it already builds shows the pattern), and on Err remove only the layers and tiles that are new, then truncate url_requests and restore active_layer as now.

Confidence: high that the cost is quadratic; medium on how much it matters in practice.

[Mavrick-F]

The feature buffers are shared, rather than deep-copied: Features wraps Arc<Vec<Feature>> (crates/data/src/lib.rs). There is still repeated layer-metadata cloning, bounded by the 1,000-record import limit. I am retaining the transactional snapshot here: deleting newly added layer/tile IDs alone does not restore other project state changed by a failed loader. A narrower transaction would need to cover those mutations before replacing this rollback.

[github-actions]

Bug (behaviour divergence): rustgis_engine::cmd::zarr::is_absent already treats 403 as missing (crates/engine/src/cmd/zarr.rs:79). The Add Zarr dialog's fetch counts 403s and fails only when every key was refused. This per-chunk check instead aborts the whole import on the first 403, while the comment above says missing chunks keep their fill values.

On a public S3/GCS bucket that answers 403 for absent keys, a store with any absent chunk fails here but loads in the dialog. If the stricter behaviour is intended, say so in the comment. Otherwise, reuse the dialog's all-refused check.

Confidence: medium. I haven't run this against a real bucket.

[Mavrick-F]

Fixed in 0687477. Imported stores now match Add Zarr: absent keys returning 403 are tolerated, missing chunks retain fill values, and metadata with no readable document and a 403 reports access denial. Added regressions for readable metadata alongside a 403, unreadable metadata, and a missing chunk returning 403. Focused tests, full cargo xtask ci, wasm build and pre-commit checks passed.

[github-actions]

Code review

I read the full diff against the repo guidelines and checked the surrounding code for the claims that depend on it. I did not build or run the tests, since I have no shell here, so this is a read-only review.

Bugs

• Zarr 403 handling (crates/ui-egui/src/geolibreui.rs:61) diverges from the Add Zarr dialog and from its own comment. Any 403 chunk aborts the import, although is_absent already treats 403 as missing. Posted inline. Confidence: medium.
• read_project rejects the whole project on a duplicate layer id, while the rest of the importer reports problems per layer. Please confirm this is intended. Confidence: low.

Security

• No exploitable issue found. layer.addDownload and project.importGeolibre are in the plugin NEVER list, add_url refuses the internal GeoLibre keys, and the assistant gate covers ui.addUrl with those keys.
• Informational: an imported project can name absolute and ../ relative local paths, and they are read. The docs say to import only trusted projects. Confidence: medium that this is intended.

Performance

• import_project deep-clones the whole project for every layer record (crates/engine/src/cmd/geolibre.rs:107). The cost grows with the import, so this is quadratic. Posted inline. Confidence: high on the cost, medium on practical impact.

Quality

• _folder in add_layer (geolibre.rs:244) is underscore-prefixed but used on wasm. The prefix exists to silence the native unused warning, so a cfg_attr would say that more clearly. Confidence: medium.
• backstage.rs:158 changes the accessible enabled flag on every project card. It is unrelated to this feature, though harmless. Confidence: medium.
• Desktop Open now accepts plain .json, which imports as data through layer.addData. This looks intended; worth confirming. Confidence: medium.
• Nit: some doc and ROADMAP lines run past the roughly 100-column wrap used elsewhere, for example the ROADMAP.md QGIS/GeoLibre line and the workspace.md "Browser imports…" line. Confidence: high.
• Nit: the temp-dir tests call remove_dir_all(...).unwrap() after their assertions, so a failed assertion leaves the directory behind. Confidence: low.

AGENTS.md

• No unwrap, expect, panic, or unsafe in non-test code. New ui-egui strings use tl!. Engine and map notes stay English, as the existing QGIS notes do.
• Layering holds: the new engine and map code has no egui dependency. Wasm paths use web_time and Services.
• No new dependencies, since Cargo.toml is unchanged, and no assets were added.
• Hostile-parameter coverage is present for the new commands.

Bug (medium confidence, high impact): browser imports reserve a placeholder layer with source = "geolibre-pending:…" while the download runs. Nothing in the save path skips or completes these placeholders (I searched the repo for the token and found no save-time handling). If the user saves before the download lands, the .rgis file contains an empty point layer that never fills in after reopen. The docs ask users to "wait before saving", but the code does not enforce it. Consider blocking or warning on save while url_requests/downloading still hold imported reservations, or dropping placeholders when saving.

[Mavrick-F]

Fixed in bab29a7. Project saves and recovery snapshots now refuse unfinished GeoLibre feature or archive reservations, rather than persisting an empty layer that cannot resume. A regression covers refusal while pending and successful saving after completion. The workspace guide describes the save restriction. Focused regressions, full cargo xtask ci, wasm build and pre-commit checks passed.

[github-actions]

Bug (low confidence): in finish_layer, if add_named_bytes adds more than one layer, the ids.len() != 1 branch returns Err without removing the extras. discard_pending only removes layers whose source is the token, so the extra layers stay in the target map. Consider removing every id added by add_named_bytes before returning the error, or snapshotting the target map's layer ids.

[Mavrick-F]

layer.addDownload is a mutating command run through Session::guarded (crates/engine/src/lib.rs). That transaction snapshots the project and restores it on Err, including layers added before the single-layer check failed. finish_layer is a helper within that transaction; discard_pending runs after rollback. Additional cleanup here would duplicate the existing transaction.

[github-actions]

Quality (scope): this changes the accessibility state of every start card (true becomes ui.is_enabled()), not only the new GeoLibre card. It is unrelated to importing GeoLibre projects. Please split it into its own change, or say in the PR body why it is needed here.

[Mavrick-F]

The GeoLibre card uses this shared accessibility metadata for its accessible button name and the actual-widget import regression. Reporting ui.is_enabled() keeps that same integration accurate when the card is disabled. This small change at the shared card seam is intentional; it does not change card layout or interaction.

[github-actions]

Nit (AGENTS.md): the notice is built with format!. Neighbouring messages in this UI use i18n::fmt, for example line 1940 of this file and serviceui.rs. Using i18n::fmt("{url}: {e}", &[("url", &url), ("e", &e)]) keeps the message translatable. The same format! pattern is copied from lib.rs (the download-failure branch), so it may be worth fixing in both places.

[Mavrick-F]

Fixed in bab29a7: the imported Zarr failure notice now uses i18n::fmt with URL and error placeholders. Focused regressions, full cargo xtask ci, wasm build and pre-commit checks passed.

[github-actions]

Nit (AGENTS.md): these graduated legend labels ("< {}", "≥ {}", and the en dash form) are user-visible English strings that are not wrapped for translation. Labels are built in L2, so either pass a translated template in from L6, or note in the PR that these labels stay English for now.

[Mavrick-F]

These generated class labels contain numbers and mathematical symbols only (<, ≥, and the range separator); they contain no English words to translate. They are generated data labels in the map layer, which cannot depend on UI translation. I am retaining their mathematical notation.

[github-actions]

Nit: _folder is named as unused, but the wasm branch reads _folder.0 and _folder.1 (lines 287–288). Renaming it to folder and dropping the underscore would avoid misleading readers. The native build can keep it unused by gating the name with #[cfg_attr(not(target_arch = "wasm32"), allow(unused_variables))], or with a let _ = folder; line.

[Mavrick-F]

Fixed in bab29a7: renamed the argument to folder, with an explicit native-only unused binding. The wasm branch uses the descriptive name. Focused regressions, full cargo xtask ci, wasm build and pre-commit checks passed.

Code review

I read the full diff (21 files, about 2,080 added lines) against the base-branch AGENTS.md and checked the key claims in the source. Six inline comments are posted. No Bash was used, so nothing was built or run.

Bugs

• Saving during a browser download persists placeholder layers (medium confidence, high impact). Reserved layers keep a geolibre-pending: source token until their download lands. Nothing in the save path skips them, and they never fill in after reopen. The docs say "wait before saving", but the code does not enforce it. Inline comment on crates/engine/src/cmd/geolibre.rs:343.
• finish_layer can leave extra layers in the target map (low confidence). If add_named_bytes adds more than one layer, the ids.len() != 1 error path returns without removing them. discard_pending only removes layers carrying the token. Inline comment on crates/engine/src/cmd/geolibre.rs:452.

Security

• Nothing blocking. Project-named local paths, URLs and dir are read on desktop as designed, and the assistant gate and plugin denylist cover the new commands. The dir behaviour is documented for trusted projects. Low concern.

Performance

• Nothing significant. The per-layer s.project.clone() is cheap if dataset features are shared, which the guarded comment suggests.

Quality

• Unrelated accessibility change to every start card (ui.is_enabled()). Inline comment on crates/ui-egui/src/backstage.rs:158.
• _folder is named as unused but read on the wasm path. Inline comment on crates/engine/src/cmd/geolibre.rs:363.
• Legend labels such as "< {}" and "≥ {}" are English-only and not translatable. Inline comment on crates/map/src/geolibre/style.rs:89.

AGENTS.md

• The notice at crates/ui-egui/src/geolibreui.rs:149 uses format! where neighbouring code uses i18n::fmt. Inline comment posted (nit).
• The PR adds a visible import card and dialogs, but the body says screenshots are "retained privately". AGENTS.md asks for screenshots in the PR for substantial visible changes.
• The picker label differs between desktop ("Projects and JSON data…") and web ("Projects (RustGIS, GeoLibre)"), although both accept .json.
• Everything else checked against AGENTS.md is in order: no unwrap outside tests (clippy.toml allows it in tests), web_time is used, and the layering and wasm paths look right.

Checked and found fine

• The browser download-slot admission matches the streaming behaviour for TIFF/COG.
• Undo and request_only handling in the import, the Zarr reader's byte budget, and the group-ancestry cycle guard.

Security (confidence ~45%). Absolute paths are opened from disk whenever they exist, even when the project came from text, data, or a url the user never chose as a local file. A remote .geolibre (for example a ?project= link on desktop) could name a local CSV or GeoJSON, and the importer would add it as a layer. The docs tell users to import only trusted projects, but the code doesn't enforce that for URL-sourced projects.

Suggestion: honour absolute paths only when the import came from path (or an explicit dir). For other inputs, resolve only relative paths against dir.

[github-actions]

Bug (confidence ~60%). On native, a remote MBTiles source is downloaded with download_blocking, which runs on the calling thread with a 60 s overall timeout. On desktop that's the UI thread, so the app can freeze for up to a minute. Archives that take longer than 60 s fail, even though the 512 MiB cap allows much larger ones.

The wasm branch already defers through request_url, and finish_archive can complete a placeholder tile. Using the same placeholder on native would avoid both problems. Otherwise, document the limit.

[github-actions]

Possible bug / UX (confidence ~50%). ensure_imports_complete makes recovery_text refuse the whole project while any browser download is pending. For that window, crash recovery is unavailable for all of the user's work, and on wasm a stalled fetch has no bound in the code.

Saving can reasonably refuse until the imports finish. Recovery is the safety net, though, so it may be better to write the completed state and leave pending layers out (or mark them as pending), rather than write nothing.

[github-actions]

Nits, grouped:

• The filter label Projects (RustGIS, GeoLibre) now admits any .json. The desktop picker says "Projects and JSON data (RustGIS, QGIS, GeoLibre)". Use one label on both.
• The notify text added at line 172 (?project= opens a project or imports a map…) is a user-visible literal that isn't wrapped in tl!/i18n::fmt. AGENTS.md requires that for interface text the PR touches.

[github-actions]

"Desktop URL imports run synchronously, like Add Data from URL" is inaccurate. Add Data from URL downloads in the background; the error text in crates/tiles/src/cache.rs says so. Only the GeoLibre import (project.importGeolibre with a url) blocks, for up to 60 s. Reword to say the import waits for the download and has that limit.

[github-actions]

Code review

This review is from reading the diff and the surrounding source. I did not compile the code or run the tests, so the claims below are static findings.

Bugs

• Native remote MBTiles import downloads synchronously on the calling thread, with a 60 s cap. The UI can freeze, and larger archives fail. Confidence ~60%. (crates/engine/src/cmd/geolibre.rs:271)
• recovery_text refuses the whole project while any browser download is pending, so crash recovery is unavailable during that window. Confidence ~50%. (crates/engine/src/project.rs:793)

Security

• Absolute local paths are read whenever they exist, including for projects from text, data or url. A remote project can make the importer load local files as layers. Confidence ~45%. (crates/engine/src/cmd/geolibre.rs:410)

Performance

• No material issues found. The per-layer project.clone() is shallow because Features is Arc-backed, and the position lookup is O(n²) over at most 1,000 layers.

Quality

• add_layer is about 150 lines, with three cfg splits and tile, feature and archive logic mixed together. Splitting it into helpers would make it easier to review.
• In the new tests, geolibre_moved_local_source_uses_project_directory and geolibre_local_source_kinds_and_archives remove their temp directories only on success. A failing assert leaks them. Confidence high.
• The Open Project picker label differs between web (Projects (RustGIS, GeoLibre)) and desktop. Confidence high.

AGENTS.md

• The notify text at apps/rustgis-web/src/web.rs:172 is an interface literal that is not wrapped in tl!/i18n::fmt. Confidence ~60%.
• The workspace.md sentence that says desktop URL imports run "like Add Data from URL" is inaccurate, because that path downloads in the background. Confidence ~80%. (docs/user-guide/workspace.md:106)
• Checked and fine: no new dependencies, no unsafe, no unwrap in non-test code, web_time used for clocks, no dialogs in commands, and translated literals in the Zarr dialog.

Checked by reading and not reproduced: group.children order was examined and is not a bug, because rendering iterates the layer list.

crates/engine/src/cmd/geolibre.rs:289-290
🎯 Functional Correctness | 🟡 Minor | ⚖️ Poor tradeoff

Preserve user edits made to the reserved MBTiles tile during download.

On the browser (wasm32) path, add_layer reserves the MBTiles tile with visible = false and a geolibre-pending: id. It then sends the import-time visible and opacity as geolibreLayer.record. When the download completes, finish_archive overwrites the reserved tile with values from that record. Any visibility or opacity change made to the reserved tile before completion is discarded.

The engine accepts such a change. The tile-setting command resolves the tile by index and writes visible and opacity with no check for pending tiles. A change made between import and completion therefore reverts to the import-time value when the download finishes. The loss is silent. The affected path is the browser build only. The native path sets the appearance immediately and creates no reserved tile.

A safe correction is not established by the inspected code. Copying the reserved tile's current values would discard the import-time values, because the reserved tile starts with visible = false. Preserving edits needs a record of which fields the user changed. That is a design change, so this comment makes no edit.

Scope of the fix

Track user changes to visible and opacity on reserved tiles. Apply the import-time record only to fields the user has not changed. Alternatively, block those edits until the download completes. Either option needs a decision from the maintainers.

Cover the pending MBTiles reservation in the save test.

geolibre_pending_layers_cannot_be_saved_as_completed_data covers only a dataset layer whose source starts with geolibre-pending:. ensure_imports_complete also rejects a map.tiles entry whose id starts with that prefix. If that tile check were removed, this test would still pass, and no other test covers the tile rejection through either save path.

Add a pending tile after the dataset marker is cleared. The tile is then the only pending reservation that both save calls can reject.

     assert!(s.project.saved_text(None).is_ok());
     assert!(s.project.clone().recovery_text().is_ok());

Guard the package writers against pending GeoLibre downloads.

project.package and map.package serialize project state without calling ensure_imports_complete. A package written while a GeoLibre layer or MBTiles archive is still downloading contains the runtime-only geolibre-pending: placeholder. The file loads without it being removed or completed. The reopened layer has no download that can finish it. Its empty dataset is saved as if it were data.

package_project (crates/engine/src/cmd/items.rs:544) clones s.project, embeds the maps and serializes the result without calling the guard. package_map (items.rs:566) does the same for the active map. Both are registered as commands with no pending-download gate (items.rs:198). The placeholder layer survives packaging because embed_layer changes only raster layers. Reopening does not remove it, so saved_text refuses to save that project until the user deletes the layer.

Add a package case to geolibre_pending_layers_cannot_be_saved_as_completed_data in crates/engine/src/tests.rs. The current test covers only saved_text and recovery_text.

Review comment at @crates/engine/src/project.rs around lines 723 - 727:
Expose Project::ensure_imports_complete within the crate and call it at the
start of both package_project and package_map so packaging rejects projects with
pending GeoLibre downloads; extend
geolibre_pending_layers_cannot_be_saved_as_completed_data to verify the package
paths also reject pending layers.
