Summary

  • add an interactive node-and-edge canvas to the existing model builder
  • export models as versioned pipeline.json DAG specifications and import compatible pipelines
  • validate imported graphs and preserve the existing sequential runner
  • translate the new controls across every shipped locale

Verification

  • loaded us_cities.geojson in the real app and ran a Buffer workflow over 109 features
  • verified the modeler canvas and controls in light and dark themes
  • verified browser download of untitled-model.pipeline.json
  • npm run test:frontend (6,300 passed, 1 skipped)
  • npm run build
  • scoped pre-commit gate

This establishes the in-app visual modeler and portable DAG format while keeping execution compatible with the current single-chain vector runner. Additional node families and branching execution can extend the schema without changing exported v1 pipelines.

Fixes #1982

📝 Walkthrough

Walkthrough

The model builder now supports validated pipeline JSON import and export, ordered workflow visualization, step selection, and localized controls. A portable pipeline schema converts sequential processing models to and from directed graphs.

Changes

Workflow pipeline modeling

Layer / File(s) Summary
Pipeline schema and conversion
apps/geolibre-desktop/src/lib/processing-pipeline.ts, tests/processing-pipeline.test.ts
Defines pipeline nodes and edges, serializes sequential models, validates graph structure, reconstructs models, and tests valid and invalid pipelines.
Model builder workflow canvas and file actions
apps/geolibre-desktop/src/components/processing/ModelBuilderDialog.tsx, apps/geolibre-desktop/src/i18n/locales/*.json
Adds pipeline import/export controls, file handling, vector-tool validation, ordered workflow rendering, step selection, selected-step styling, isolated card controls, and localized labels.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 83bf4

The modeler is mergeable with owner follow-up: overlapping or slow imports may replace newer unsaved edits, and a few localized labels remain inconsistent or incorrectly assigned in supported languages. These are bounded user-facing issues but should be corrected or explicitly accepted.

Poem

A rabbit checks each node in line,
Then saves the graph as JSON design.
Import, export, select, and flow,
With linked steps in ordered row.
New labels guide the canvas bright—
Hop hop, the workflow is right!

Code review

Bugs

  • ModelBuilderDialog.tsx:909 (StepCard's wrapping onClick={onSelect}) — clicking the Remove button (or any other in-card control) bubbles up to onSelect, and because both setSelectedStepId calls batch into the same update, the bubbled call runs after removeStep's cleanup and re-sets selectedStepId to the id of the step that was just deleted — even when a different step was selected. Net effect: removing any step silently clears/corrupts the current highlight. Confidence: high. Inline comments include a fix (stopPropagation() on the remove button).

Security

  • None found. Import path (pipelineToModel) validates schema/version, node shape, and edge topology before touching state, and all parsing is wrapped in try/catch in handleImport.

Performance

  • None found. Pipeline validation is linear in nodes/edges; canvas rendering is a simple list, no obvious inefficiencies for the expected step counts.

Quality

  • processing-pipeline.ts:62-68 — two minor validation gaps in pipelineToModel's node-shape check: typeof node.params !== "object" also accepts arrays, and node.type?.startsWith(...) throws a raw TypeError (rather than the intended message) if type is present but non-string. Both are already caught by the caller's try/catch, so low severity/confidence.
  • The cycle/branch/disconnected-chain rejection logic in pipelineToModel is subtle (e.g. it relies on the edges.length === nodes.length - 1 invariant plus per-node in/out-degree ≤ 1 to reject cycles-mixed-with-chains); I traced through several adversarial cases (2-node cycle, isolated chain + separate cycle, duplicate edges) and it holds up correctly, but only the "branching" case is unit-tested — a cycle-rejection test and a "multiple disconnected chains" test would make the invariant less fragile to future edits.
  • apps/geolibre-desktop/src/i18n/locales/vi.json has a ~490-line diff that is almost entirely unrelated key reordering (whole top-level sections like common, statusBar, shell, raster, vectorExport moved, with identical content) rather than genuine translation changes — looks like rebase/merge churn rather than intentional work. Not a bug, but it bloats the diff and is worth squashing/regenerating before merge. Low confidence this is actionable vs. tooling-driven.
  • Minor: the <div onClick={onSelect}> wrapper on StepCard (and by extension the same pattern for the whole card) is a mouse-only interaction with no keyboard equivalent (tabIndex/onKeyDown); low-severity a11y nit, not required by CLAUDE.md's i18n/a11y guidance but worth a note.

CLAUDE.md

  • No violations found. New user-facing strings go through t() and are translated in all shipped locales; the canvas connector arrow correctly uses logical Tailwind classes (border-s-8, border-s-primary/60) rather than physical border-r-, matching the RTL-support convention; the export flow reuses the existing URL.createObjectURL + anchor-download pattern already used in ProcessingDialog.tsx, so it's consistent with the rest of the codebase.

Inline comments:
In `@apps/geolibre-desktop/src/components/processing/ModelBuilderDialog.tsx`:
- Around line 837-839: Replace the hardcoded “transform” label in
ModelBuilderDialog with the existing translation function t(), then add the
corresponding translation key and value to every supported locale catalog.
- Around line 907-910: Prevent the Remove action from bubbling to the step
container’s onClick handler, so removeStep can clear selection without
reselecting the deleted step. Update the Remove button/action near the step card
rendered by ModelBuilderDialog while preserving normal step selection behavior.

In `@apps/geolibre-desktop/src/i18n/locales/vi.json`:
- Around line 5388-5415: Update the shell.section.pluginPanelRightOfLayers
translation to describe the plugin panel positioned to the right of the Layers
panel, replacing the unrelated “Cancel” label while preserving the surrounding
Vietnamese localization style.
- Around line 1559-1577: Correct the pixelTimeSeries translations for the
chartAria, gapNote, and close keys so each value describes its own action or
message: chartAria should label the chart, gapNote should describe the
panel-size change, and close should provide the close action label. Preserve the
surrounding Vietnamese translations and placeholders.
- Around line 5275-5284: Update the raster.filePickerLabel translation to use
the locale’s existing file/source label rather than “Giá trị” (“Value”), keeping
the key scoped to the raster file picker.
- Around line 800-802: Update the Vietnamese offline.timeoutDisabled translation
to describe disabling or replacing the offline request-timeout setting, rather
than asking about replacing tour keyframes; preserve the existing interpolation
and wording conventions used by the adjacent timeout entries.
- Around line 202-205: Correct the Vietnamese translations in
fileNamePrompt.label and the planetSwitcher entries: restore
fileNamePrompt.label to the file-name prompt meaning, restore planetSwitcher.io
and planetSwitcher.titan to their respective planet labels, and replace
planetSwitcher.europa’s duplicated picker text with Europa’s label. Use the
corresponding translations from the surrounding locale keys or other locales as
the source of truth.
- Around line 3207-3219: The Vietnamese Mapillary translations use generic
wording in mapillary.tokenLabel and mapillary.title; update both values to
explicitly retain the product name “Mapillary” while preserving the surrounding
translation and meaning.
- Around line 1732-1761: The Vietnamese translations in knowledgeCard and
onboarding do not match their keys: update knowledgeCard.readMore to a “read
more” label, onboarding.description to an onboarding description, and the
intermediate and advanced level titles to accurately describe their respective
levels. Keep the surrounding translations unchanged.
- Around line 3641-3677: Update the pythonConsole.showEditor and
pythonConsole.hideEditor localization strings to describe showing and hiding the
Python editor, replacing the unrelated note-content and notebook-panel resize
text while preserving the surrounding localization structure.
- Around line 1691-1700: Update the mapContextMenu.centerHere translation to use
a clear Vietnamese imperative command for centering the map at the clicked
location, replacing the current awkward phrasing while leaving the other map
context menu translations unchanged.
- Around line 3763-3787: Update the assistant.title translation to a concise
assistant panel heading rather than the code-execution approval message, and
change assistant.model to the Vietnamese label for an AI model. Keep the
surrounding assistant translations unchanged.

In `@apps/geolibre-desktop/src/lib/processing-pipeline.ts`:
- Around line 58-68: Update the pipeline node validation in the loop over nodes
to reject empty string IDs, require node.type to be a string before calling
startsWith, and require node.params to be a non-array object. Validate that
inputParam is a string before reconstructing steps or passing it to the runner,
and preserve the validated node.id directly.

Code review

Bugs

  • None found with high confidence. The new pipelineToModel/modelToPipeline DAG validation (apps/geolibre-desktop/src/lib/processing-pipeline.ts) was traced through several edge cases (empty pipelines, disconnected components, cycles mixed with valid chains, branching) and correctly rejects all of them via the edge-count check plus the final ordered.length !== nodes.length guard — well covered by tests/processing-pipeline.test.ts.

Security

  • None found. Import reads the file client-side with file.text() + JSON.parse; no eval, no prototype-pollution vector (JSON.parse doesn't trigger the special __proto__ setter), and the export filename is slugified to [a-z0-9-] before being used as a download attribute.

Performance

  • None found; the canvas and validation logic operate on small, in-memory step lists.

Quality

  • ModelBuilderDialog.tsx:838 — the canvas step badge hardcodes the English word "transform" instead of using t(), unlike every other new string in this PR. Confidence: high.
  • ModelBuilderDialog.tsx:909 — the newly added onClick={onSelect} on the StepCard wrapper <div> has no role/tabIndex/keyboard handler, so step selection isn't reachable via keyboard, inconsistent with the accessible <button> nodes used in the new WorkflowCanvas. Confidence: medium.
  • handleExport's filename slug (ModelBuilderDialog.tsx:552-558) strips all non-[a-z0-9] characters, so a model named entirely in a non-Latin script (e.g. CJK, Arabic) silently downloads as pipeline.pipeline.json with no trace of the given name. Confidence: low-medium, minor UX only.

CLAUDE.md

  • The hardcoded "transform" label above is a direct miss of the "Use t() for new user-facing strings" convention; flagged inline. Confidence: high.
  • Most locale files carry large, functionally-inert diffs (e.g. the auth block relocated in ~13 locales, and a much bigger key reordering in vi.json) that don't change any translated content — just churn unrelated to this feature. Not a defect, but it substantially inflates the diff and obscures the actual translation additions during review. Confidence: medium.

Comment thread tests/processing-pipeline.test.ts Outdated
- Revert the incidental key reordering of all 18 non-English locale
  catalogs. The reorder rewrote vi.json wholesale (983 lines) without
  changing a single value, which made CodeRabbit read pre-existing main
  content as newly added and flag 11 translation defects this PR never
  introduced. Each catalog now adds only the new keys in place.
- Localize the workflow canvas step-kind badge: the hardcoded
  "transform" label becomes processing.modelBuilder.stepKindTransform,
  translated across every shipped catalog.
- Reject empty pipeline node ids and non-string inputParam values in
  pipelineToModel, and keep the validated node.id instead of minting a
  replacement, so a hand-edited pipeline fails validation rather than
  reaching the runner with an invalid parameter key.
- Cover the new validation and id preservation in
  tests/processing-pipeline.test.ts.

Code review

Bugs

  • None found. The DAG validation in pipelineToModel (schema/version check, unique node ids, single in/out-degree per node, edge-count-vs-node-count check, and a final chain-walk length check) correctly rejects branches, merges, cycles, disconnected components, and cycle-plus-dangling-path graphs — traced through several adversarial cases by hand and they all resolve to a thrown error rather than silent corruption. Confidence: high.

Security

  • No injection, XSS, or unsafe-input issues found. Imported JSON only ever flows into React text nodes (auto-escaped) or into parameters/toolId strings validated against the registry before use; the exported filename is slugified to [a-z0-9-] before use as a download name, ruling out path-traversal-style names. Confidence: high.

Performance

  • No notable issues; import/export operate on small, user-authored pipeline JSON, and validation is linear in node/edge count.

Quality

  • pipelineToModel's "Branching pipelines are not supported yet" error is reused for both fan-out (branch) and fan-in (merge) rejections, which can misdirect a user debugging a rejected merge-shaped import. (apps/geolibre-desktop/src/lib/processing-pipeline.ts:81-82) — medium confidence.
  • The new WorkflowCanvas empty state duplicates the exact same emptyPipelineHint string already shown by the step list below it, so the message appears twice on screen simultaneously when a model has no steps. (ModelBuilderDialog.tsx:812-815) — medium confidence.
  • StepCard's root <div> gained an onClick={onSelect} making the whole card a click target, but it has no role="button"/tabIndex/keyboard handler, so keyboard-only users can't select a card the way canvas nodes (which are real <button>s) support. (ModelBuilderDialog.tsx:907-910) — medium confidence.
  • Minor/low-confidence: in pipelineToModel, the starts.length !== 1 cycle check (line 91) appears to be unreachable given the preceding edge-count and degree checks always force exactly one start when they pass — the actual cycle/disconnection detection happens later via ordered.length !== nodes.length. Not a correctness issue since the later check still catches it, just redundant/dead code worth a comment if noticed during future maintenance. Not filed as an inline comment since it doesn't affect behavior.

CLAUDE.md

  • New UI correctly uses logical Tailwind utilities (text-start, border-s-8, etc.) for the RTL-mirrored workflow canvas arrows, per the i18n convention. All 19 locale files received the four new translation keys consistently. No violations found.

907-910: 🎯 Functional Correctness | 🟡 Minor

Make the secondary step-card selector keyboard accessible.

StepCard attaches onClick={onSelect} to a plain <div> at Lines 907-910. The card is not focusable and has no Enter or Space handler. Keyboard users can use the canvas buttons, but this selection path remains mouse-only. Use a native button for the selection surface or add a separate focusable selection control. Keep move and remove buttons outside that control.

- Make the step card keyboard-selectable. The card root's onClick was
  mouse-only; role="button" on the root is not an option because it wraps
  the parameter inputs, so the step title becomes a real button with
  aria-pressed, matching the canvas node pattern.
- Give the workflow canvas its own empty-state string. It rendered the
  same emptyPipelineHint the step list shows, so the identical sentence
  appeared twice whenever a model had no steps.
- Report fan-in as "Merging pipelines are not supported yet" instead of
  reusing the branching message, which misled on a merge import.
- Cover the cycle branch that the existing test never reached: its
  two-node loop carries two edges and is rejected by the earlier
  edge-count check, so add a three-node fixture with a chain-sized edge
  count that still leaves an untraversed loop, plus a merge-message test.

Bugs

  • apps/geolibre-desktop/src/components/processing/ModelBuilderDialog.tsx:548-562handleExport revokes the object URL synchronously right after anchor.click() and never attaches the anchor to the DOM first. Two sibling download helpers in this same file's neighborhood (ProcessingDialog.tsx's downloadBytes, GeoreferencerDialog.tsx's download) both appendChild/remove the anchor and defer the revoke via setTimeout(..., 0), with a comment explicitly noting Firefox drops the download if revoked synchronously. This PR reintroduces that already-fixed bug, so pipeline exports may silently fail or be truncated in Firefox. Posted inline with a suggested fix. Confidence: medium-high.

Security

  • None found. Import parses with JSON.parse (no eval), the exported filename slug is sanitized to [a-z0-9-], and no user-controlled content reaches dangerouslySetInnerHTML or a URL that's fetched/executed.

Performance

  • No obvious issues. pipelineToModel's graph validation and walk are linear in the number of nodes/edges; large imports would only be bounded by file.text()/JSON.parse on the main thread, which is consistent with how other import paths in this app already work.

Quality

  • pipelineToModel (apps/geolibre-desktop/src/lib/processing-pipeline.ts) never validates imported params values against the target tool's parameter schema — only tool existence is checked in handleImport. A malformed value (e.g. a string where a number is expected) will surface only as a runtime error when that step runs, not at import time. This is likely acceptable given runModel already handles per-step failures gracefully, but worth a conscious call. Confidence: low.
  • ProcessingPipelineNode.name is typed as required but is never validated or used by pipelineToModel — harmless, but a minor mismatch between the declared interchange schema and what's actually enforced. Confidence: low.
  • The cycle/branch/merge validation logic in pipelineToModel is otherwise carefully constructed and well covered by the accompanying tests (including the subtle "matching edge count but disconnected cycle" case) — no correctness issues found there.

CLAUDE.md

  • No violations found. New interactive elements use logical Tailwind properties (border-s-*) for RTL correctness as required, translation keys were added consistently across all locale files, and the existing convention of hardcoded (non-t()) log strings in this component's appendLog calls is followed consistently by the new import/export log lines.

Code review

Bugs: None found. The DAG import validator (pipelineToModel in apps/geolibre-desktop/src/lib/processing-pipeline.ts) correctly handles out-of-order edge lists, branching, merging, self-loops, disconnected components, and cycles that coexist with a valid-looking edge count — all backed by targeted tests. Selection state (selectedStepId) is purely cosmetic and has no stale-reference risk after step removal/import/reorder. Export/import round-trips inputParam and step order correctly. (High confidence.)

Security: No injection, XSS, or prototype-pollution concerns. Imported JSON is validated with Map-based lookups (immune to __proto__ tricks), rendered only as React text (auto-escaped), and unknown tool IDs are explicitly rejected before being applied to the draft. (High confidence.)

Performance: No issues; canvas rendering and pipeline parsing are O(n) over steps/nodes with no unnecessary re-renders introduced. (High confidence.)

Quality:

  • ProcessingPipelineNode.name is written on export but never validated or read back on import — effectively decorative; harmless but could confuse a future maintainer (medium confidence, minor).
  • A duplicate edge in an imported pipeline is rejected with the "Branching pipelines are not supported yet" message, which is slightly misleading since the actual problem is a repeated edge rather than true branching; the import is still correctly rejected either way (low confidence, cosmetic).
  • Parameter values on imported steps aren't shape/type-validated against the target tool's schema (only tool existence is checked) — but this matches the existing, documented trust model for project-file loading (normalizeModels in packages/core/src/project.ts), so it's consistent with precedent rather than a new gap (low confidence).

CLAUDE.md: Compliant. New user-facing strings use t() and are translated across all locale files; the workflow canvas's directional arrow uses logical Tailwind utilities (border-s-*) rather than physical border-l-*, correctly supporting RTL locales; the new pipeline logic is tested via a dedicated leaf module (tests/processing-pipeline.test.ts) rather than pulling in the whole plugin registry, avoiding the coverage-regression trap called out in CLAUDE.md.

Overall this is a clean, well-tested addition — only minor, non-blocking nits posted inline.

568-583: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Prevent stale imports from overwriting newer draft state.

handleImport awaits file.text() while the editor remains active. If the user selects file A and then file B, or edits the draft while A is loading, A can finish later and overwrite the newer state.

Track an import revision and apply the result only when it is still current. Invalidate the revision when a new draft or another draft edit supersedes the import, or disable draft actions while importing.

Proposed guard for overlapping imports

Bugs

  • Importing a .model.json/pipeline.json with nodes but no edges array passes handleImport's validation (only nodes is checked), leaving graph.edges === undefined; GraphEdges later does graph.edges.map(...) unconditionally and throws outside the try/catch, tripping the panel's error boundary instead of a friendly error. (ModelBuilderPanel.tsx:283, high confidence)
  • validateModelGraph has no duplicate-node-id check and silently drops (rather than reports) edges referencing nonexistent nodes — both let a corrupted imported graph pass validation while runModelGraph/graphToLinearSteps behave in silently wrong ways. Neither case is tested. (packages/processing/src/model-graph.ts:159-184, medium confidence)
  • No Cancel affordance ever calls abortRef.current?.abort(), and starting a new/imported/loaded model while a run is in-flight doesn't abort it — the abandoned run's closure keeps writing logs/layers/node status into the new session. (ModelBuilderPanel.tsx:443-490, medium confidence)
  • Dragging a node has no collision/z-order handling (only initial placement via findFreePosition does), so dragging one node onto another can permanently hide the covered node's connector ports. (ModelBuilderPanel.tsx:359-365, low-medium confidence)
  • (err as Error).message in runModelGraph's catch block assumes rejections are always Error instances; a non-Error rejection from the caller-supplied executeTool would throw inside the handler itself. (packages/processing/src/model-graph.ts:388, low confidence)

Performance

  • topologicalOrder's ready-queue uses Array.shift(), making it O(n²) on wide-fan-out graphs; it's recomputed on every graph edit and there's no size cap on imported files, so a large/malformed import could hang validation before a run starts. (packages/processing/src/model-graph.ts:110, medium confidence)

Quality

  • BatchToolsDialog.tsx (the file left behind after splitting the old ModelBuilderDialog) imports modelToPipeline/pipelineToModel, ProcessingModel(Step), runModel, Separator, and several icons that are never used — the "Models" tab that used them appears to have been dropped mid-split. As a result, processing-pipeline.ts's schema-validated pipeline.json v1 format (with its own thorough test suite) is unreachable dead code, while ModelBuilderPanel.tsx implements a separate, weaker, unversioned .model.json format instead — two incompatible model-interchange formats now coexist. Worth confirming with the author which one should actually ship. (high confidence)
  • Relatedly, the old dialog's "delete a saved model" affordance (the store's deleteModel action) has no caller left anywhere in the UI after the split — saved models can only be created/loaded now, not removed short of hand-editing the project file.

CLAUDE.md adherence

  • No violations found: i18n locale files all add the identical key set as en.json with placeholders preserved (spot-checked 9 locales); the th/vi diff-size difference is just an incidental retranslation of a pre-existing key, not a structural gap. project.ts's schema changes are additive and degrade old projects gracefully. Store wiring (batchToolsOpen) mirrors the existing modelBuilderOpen pattern correctly.

Reviewed: packages/processing/src/model-graph.ts, model-graph-edit.ts, model-tool-catalog.ts, processing-pipeline.ts, ModelBuilderPanel.tsx, BatchToolsDialog.tsx, packages/core/src/{project,types,store}.ts, DesktopShell.tsx/ProcessingMenu.tsx wiring, all i18n locale diffs, and all four new test files. No security issues (XSS, prototype pollution) were found — file-provided data goes through React's escaping and Map-keyed lookups throughout.

giswqs added 2 commits August 17, 2026 22:38
Testing the raster path against a real DEM (2880x1773, Oregon Cascades)
turned up two defects that no unit test would have caught.

The WASM runner builds its CLI arguments by walking `request.tool.params`,
and the executor never passed `tool` — so every Whitebox node ran with no
arguments at all and the binary rejected it with "missing required
parameter 'input_dem'". ModelToolDescriptor now carries the provider's own
tool record as `native` and the executor hands it back to the runner.

`resolveInput` was synchronous and only understood `layer.geojson`, so an
input node pointing at a raster resolved to null and the run stopped before
the first tool. It is now async and fetches a raster layer's bytes through
the same `fetchLayerBytes` path the Whitebox toolbox uses, so a locally
loaded GeoTIFF resolves via its blob URL rather than an unreadable path.

Verified end to end in the browser: Input(dem.tif) -> Fill Depressions ->
D8 Pointer -> Output ran both tools in sequence, each writing a GeoTIFF
converted to a COG, and added the D8 pointer raster to the map. Running the
same two steps offline confirms the semantics: Fill Depressions raises
59,455 cells (4.07%) by at most 14.789 m and is monotone over the input,
and the D8 pointer grid holds exactly {0,1,2,4,8,16,32,64,128} — every
non-zero value a power of two, as the D8 encoding requires.
- Validate an imported model through core's normalizeModelGraph instead of
  an `Array.isArray(nodes)` spot check. A file with `nodes` but no `edges`
  key passed the old check and reached the canvas with `edges: undefined`,
  which threw out of GraphEdges' render — past the importer's try/catch —
  into the panel's error boundary rather than showing importInvalid.
  Exports now carry $schema/version so a stray JSON is rejected by name.
- Delete lib/processing-pipeline.ts and its test. The split left it with
  no caller, so the repo carried two incompatible model-interchange
  formats and only the graph one was reachable. Removing it leaves the
  versioned .model.json as the single format.
- Drop the imports BatchToolsDialog stopped using when the Models tab left.
- Report duplicate node ids and dangling edges from validateModelGraph
  instead of silently collapsing or skipping them, and stop counting
  dangling edges in graphToLinearSteps, where they could make a node look
  like it had the single predecessor that projection requires.
- Drain the topological queue with an index cursor; shift() is
  O(remaining) per call, and this recomputes on every graph edit.
- Report a non-Error rejection from executeTool instead of reading
  `.message` off it, which threw inside the handler and escaped as an
  unhandled rejection.
- Settle a dragged node on drop so it never comes to rest covering another
  card, and repaint it last. Overlapping cards swallow the hit-test for the
  ports underneath, which left them unclickable with no way back.
- Add a Cancel button and abandon an in-flight run on close, New, Import
  and Load. The abort controller was stored but never fired, so a stuck
  WASM job could not be stopped, and a superseded run kept writing log
  lines, node highlighting and result layers into the session that replaced
  it.

Bugs

  • resetRunState() (ModelBuilderPanel.tsx:238-242) never clears running, so New Model / Load Model / Import while a run is active leaves the panel stuck showing the Cancel/spinner button for a session that's already gone — the real Run button stays hidden until the user clicks the stale Cancel button once more. High confidence.
  • handleRun's raster emitOutput branch (ModelBuilderPanel.tsx:492-501) calls void onAddRaster(...) with no .catch — a rejection becomes an unhandled promise rejection and the run still reports success. Medium confidence.
  • Pre-flight issues (ModelBuilderPanel.tsx:206-212) is gated on catalog.length, so if the Whitebox catalog/WASM manifest fetches both fail, validation silently stays empty forever and the Run button never disables, deferring every "unknown tool" failure to runtime with no distinct "catalog didn't load" indicator. Medium confidence.

Security

  • No findings beyond the robustness item below — nothing suggesting injection, unsafe eval, or leaked secrets in the changed code.

Performance

  • autoLayout's resolveDepth (model-graph-edit.ts:270-305) recurses per node along ancestor chains with no cap on imported node/edge counts (normalizeModelGraph in project.ts has none either), so a very large/malicious pipeline.json could exhaust the call stack before validation runs. Low-medium confidence, narrow scenario.
  • (Not filed inline, lower priority) canvas drag handlers call setGraph on every raw pointermove with no throttling and neither GraphNodeCard nor GraphEdges is memoized — likely fine for typical graph sizes but could jank on larger ones.

Quality

  • BatchToolsDialog.tsx carries dead imports (Input, Download, Layers, Plus, cn) and an unused createId() helper left over from splitting the old combined dialog. High confidence.
  • BatchToolsDialog's JSDoc (lines 141-148) still describes the old two-tab ("Batch"/"Models") dialog even though Models moved to ModelBuilderPanel.tsx. High confidence.
  • Palette tool entries (ModelBuilderPanel.tsx:766-778) are drag-only divs with no onClick/onKeyDown/tabIndex — the only way to add a tool node, which blocks keyboard/assistive-tech users from the feature's core interaction entirely. GraphNodeCard has the same gap for selecting/moving placed nodes. High confidence.

CLAUDE.md

  • Port labels "Output"/"Input" for input/output nodes are hardcoded English in both model-graph.ts's portsFor and ModelBuilderPanel.tsx's portsOf, reaching rendered titles and an aria-label t() interpolation untranslated — at odds with CLAUDE.md's "Use t() for new user-facing strings" and the PR's own translation claim. High confidence.
  • ModelGraphIssue.message is documented as an "English fallback" specifically so the UI can translate via the accompanying code field, but ModelBuilderPanel.tsx renders issue.message verbatim with no such translation — every validation/run error stays English in all locales. High confidence.

Everything else — the DAG/topological-sort logic, cycle detection, normalizeModelGraph import sanitization, the graph↔linear-steps projection, the store/menu wiring for the new BatchToolsDialog/ModelBuilderPanel split, and the i18n key sets across all 19 locale files — checked out correctly with no issues found.

- Clear `running` in resetRunState. My previous commit introduced this:
  abortRun() nulls the ref, so the in-flight run's `finally` no longer
  matched its own controller and never cleared the spinner, leaving a stale
  Cancel button for a model that was no longer loaded.
- Catch a rejected onAddRaster instead of firing it with a bare `void`. It
  became an unhandled rejection while the run still reported success for an
  output that never reached the map; failures are now logged and subtracted
  from the summary count.
- Block Run and say so when both tool registries fail to load. `issues` was
  gated on a populated catalog, so an offline session left it empty and the
  button enabled for a graph of nodes that would each fail individually.
- Translate validation issues by their `code`. ModelGraphIssue documents
  the code as existing precisely so the UI can translate, but the panel
  printed the engine's English `message`; every validation problem was
  English-only in all 19 locales. Issues now carry a `detail` field so a
  port name or tool id can be interpolated rather than parsed back out.
- Stop hardcoding "Input"/"Output" port labels in @geolibre/processing,
  which has no i18n access. They are stable ids now, resolved for display
  at the UI layer.
- Make palette entries real buttons that add a node on activation. Dragging
  was the only way to place a tool node, so the panel's core interaction
  was unreachable by keyboard.
- Rewrite autoLayout's depth resolution iteratively and cap import size.
  It recursed one frame per edge before any validation, so a long chain in
  an imported file could exhaust the stack instead of failing gracefully.
- Drop the rest of BatchToolsDialog's dead imports and its createId helper,
  and correct the doc comment that still described the Models tab.

All three inline comments are posted. Now writing the final summary.

Code review

Bugs

  • ModelBuilderPanel.tsx (handleRun, ~L517-571): raster outputs are added via a fire-and-forget onAddRaster(...) promise that isn't awaited before the run's summary line is logged, so failedOutputs.length is almost always still 0 when "N output(s) added" is printed — the count can silently overstate success and a later failure message contradicts it. Confidence: medium.
  • ModelBuilderPanel.tsx (catalog-load effect, ~L171-199): the effect is gated on catalog.length > 0, but catalog always contains the built-in VECTOR_TOOLS regardless of fetch outcome, so it only ever runs once per panel lifetime. If both the Whitebox catalog fetch and the WASM manifest load fail together on that first attempt, catalogFailed stays true (disabling Run) for the rest of the session with no retry short of a full app reload. Confidence: medium.

Security

  • None found. Import handling (normalizeModelGraph, schema/size checks in handleImport) looks appropriately defensive against malformed/oversized/hostile pipeline files, and all user-facing text is rendered through React (no dangerouslySetInnerHTML). Confidence: high.

Performance

  • No significant issues found. topologicalOrder/autoLayout avoid the classic Array.shift() O(n²) pitfall, and imported-graph size is bounded (MAX_IMPORT_NODES/MAX_IMPORT_EDGES) before layout runs. Confidence: medium.

Quality

  • BatchToolsDialog.tsx (L26): Download, Layers, and Plus are imported from lucide-react but never used — leftover from the split out of the old combined ModelBuilderDialog.tsx. Confidence: high.
  • The PR description mentions exporting pipeline.json/untitled-model.pipeline.json, but the shipped code (ModelBuilderPanel.tsx handleExport) writes <slug>.model.json. Likely just a stale description rather than a code defect, but worth reconciling. Confidence: low.

CLAUDE.md

  • No violations found. New user-facing strings go through t() and are present across all locale files with matching keys; no MapLibre control CSS or node_modules edits; no dependency/version-mirrored constants (Whitebox WASM zoom caps, etc.) were touched by this PR. Confidence: medium-high.

- Await the host's raster adds before logging the run summary. They are
  fire-and-forget promises that settle after runModelGraph returns, so the
  failure count was always read as zero and the summary claimed outputs
  that were about to fail, contradicted a moment later by the error line.
- Stop catalogFailed latching for the session. The load effect was gated on
  catalog.length, which VECTOR_TOOLS alone makes non-empty, so a first
  attempt where both remote sources failed never retried and left Run
  disabled even for a pure client-side model. It now gates on a real
  loaded flag that only a successful attempt sets, reopening the panel
  retries, and the message carries a Retry button.
- Drop the last unused icon imports from BatchToolsDialog. My previous
  trim was line-based and missed them once the import collapsed onto one
  line.

All findings have been posted as inline comments. Here is the final summary.

Code review

Bugs

  • ModelBuilderPanel.tsx (portsOf, ~L1112-1120): the synthetic input/output node ports are labeled with hardcoded English "Output"/"Input" instead of the port ids ("out"/"in") that portLabel() expects, so the translation lookup in portLabel never matches and the port tooltip/aria-label text stays English-only in every locale. Confidence: high.

Quality / CLAUDE.md

  • en.json (and all 18 other locale files): the toolbar rename from "Batch & Models" → "Model Builder" / new "Batch tools" entry only touched toolbar.item.*. The parallel toolbar.command.modelBuilder key used by the Ctrl+K Command Palette (TopToolbar.tsx:1427) was left as the stale "Batch & Models" text, and no toolbar.command.batchTools entry/command was added, so Batch Tools has no command-palette entry at all. Confidence: high.
  • BatchToolsDialog.tsx:412: the "Run batch" button text is a hardcoded English string rather than using t(), unlike the rest of the file (and CLAUDE.md's i18n convention). Carried over from the deleted ModelBuilderDialog.tsx, but now sits in a freshly created file. Confidence: medium.

Performance (not inline-commented, noted for awareness)

  • Node dragging calls setGraph on every pointermove, which re-runs validateModelGraph (via the issues memo) and recomputes canvasExtent each frame; for graphs near the documented MAX_IMPORT_NODES/MAX_IMPORT_EDGES caps (2000/4000) this could make dragging noticeably laggy. Low confidence — typical hand-built models are far smaller.
  • handleImport fully JSON.parses and normalizes an imported file before normalizeModelGraph's node/edge count cap can reject it, so an oversized file still pays full parse/normalize cost before being refused. Low confidence — self-inflicted (user picks the file), not a remote attack surface.

Security

  • No injection, unsafe eval, or XSS issues found; all rendered strings go through React's normal escaping, and imported JSON is only ever parsed/normalized, never executed.

Overall, the core graph engine (packages/processing/src/model-graph.ts), the edit helpers (model-graph-edit.ts), and the catalog adapters (model-tool-catalog.ts) are carefully written with good edge-case handling (cycles, dangling edges, duplicate ids, non-recursive depth resolution) and solid test coverage. The issues found are localized to the new UI panel's i18n wiring rather than the underlying model.

- Use the port id constants in the panel's local portsOf, mirroring the
  engine's portsFor. I fixed the engine last round but left this copy
  returning the display strings "Output"/"Input", so portLabel's comparison
  against the ids never matched and the English word reached the port title
  and aria-label in every locale — the exact leak that change was meant to
  close.
- Retitle the Command Palette's Model Builder entry, which still read
  "Batch & Models" in all 19 catalogs because toolbar.command.modelBuilder
  is a separate key from toolbar.item.modelBuilder, and register a Batch
  tools command so that dialog is reachable from the palette at all.
  Keywords now match each entry rather than mixing both concepts.
- Put the Batch dialog's "Run batch" through t(), with the key added to
  every catalog.

Waiting for the three background review agents to finish analyzing the core graph logic, canvas UI, and batch/store changes.
