Summary

Publishing a layer back to its GeoJSON file (#2036) refused any file with a bbox, the optional extent member the GeoJSON standard allows on a collection or feature. Publish now recomputes the box from the coordinates it writes, so files from tools and feeds that include one can be published.

• A collection's bbox covers every written geometry; a feature's covers its own. A feature gets one when the source's features had them, so an added row gets one too.
• A number that's unchanged keeps its original spelling, like the coordinates ([1,2,5,6] stays integers).
• A source bbox that doesn't match the file's own coordinates (stale, rounded, antimeridian-crossing or 3D) fails the existing round-trip check and is refused, so a wrong box is never written back. A bbox on a geometry object stays refused, as before.

Testing

• New regression a_bbox_is_recomputed_from_the_edited_geometry: an attribute edit leaves the boxes as they were, and moving a point updates its feature's box and the collection's.
• The refusal table gains a collection bbox that doesn't match its coordinates.
• Data-crate publish tests, Clippy with warnings denied, the WebAssembly check, and the full Linux CI on the fork pass.

Summary by CodeRabbit

• Bug Fixes
  • GeoJSON publishing now recomputes feature and collection bounding boxes from the geometries being written, including coordinates within GeometryCollections.
  • Feature bounding boxes are retained or added according to changes in row order and count; features without geometry are written without bounding boxes.
  • Publishing refuses documents when existing bounds do not match the rebuilt output, a collection bounding box has no geometry to describe, or unsupported bounding boxes are present.
• Documentation
  • Clarified which mixed-property collections and bounding-box cases are refused during publishing.

Walkthrough

GeoJSON publishing now recomputes feature and collection bounding boxes from written geometries when the source contains those boxes. Tests cover attribute and geometry edits, row changes, and refusal conditions. The publishing documentation describes bounding-box updates and refusal conditions.

Full details: Title check

Explanation

The title names the main change: GeoJSON publish now recomputes a bbox rather than refusing the file. The raw summary and objectives confirm that publishing recomputes collection and feature boxes from written coordinates and no longer refuses files with a bbox. The title is specific and concise, and it follows the conventional commit format. It does not mention the refusal that still applies for mismatched source boxes or geometry-level bbox, but it does not need to cover every detail.

Full details: Description check

Explanation

The description follows the template's Summary, Testing, and Related issue sections. The Summary explains the change and the reason for it, including how bbox values are computed, how source boxes that do not match are refused, and that geometry-level bbox stays refused. The Testing section names a new regression test, a refusal table update, and the CI checks run. The Related issue section lists a follow-up to #1385 and #2036. The UI evidence section is missing. The template requires it, but the author did not replace the placeholder line with 'No visible UI change.' The change touches only publish output, so the correct content is that line. The section is absent from the description, so the author should add it.

Resolution

Add the '## UI evidence' section with the line 'No visible UI change.' as the template requires. The change affects only GeoJSON publish output, so no screenshots are needed.

Silent loss of a source bbox (AGENTS.md "Never silent"). When the edit leaves no geometry to bound, total is None, so the collection's bbox is omitted from the output without a refusal or notice. The round trip doesn't catch it: the edited document is compared with its own re-read, and both lack the member. Concrete case: a layer with no fields (so the empty-schema check at line 63 doesn't fire) whose source has a collection bbox; delete every row and publish. The file is rewritten with no bbox, and nothing says so. A feature-level bbox has the same gap: when own is None at line 170, a row that had a box loses it.

Refusing is the rule the PR already applies to a source box it can't reproduce, so the fix can follow that pattern (confidence about 70%):

Suggested change

	if let Some(total) = total.filter(|_| original.get("bbox").is_some()) {
	out["bbox"] = json!(total);
	}
	if original.get("bbox").is_some() {
	out["bbox"] = json!(total.ok_or("its bbox can't be recomputed because no geometry is left to bound it; export a copy instead")?);
	}

The feature-level case needs a matching guard, for example refusing when originals.get(i) had a bbox and own is None. A test should cover the all-rows-removed case, asserting refusal and an unchanged file.

[Mavrick-F]

Fixed in 09af867 for the collection: a source bbox with no geometry left to bound is refused, and the file is left unchanged (a_collection_bbox_with_nothing_left_to_bound_is_refused).

A feature whose geometry was cleared is written without a box. That isn't a loss: a box describes a geometry, and there's none left. Refusing would also refuse valid files whose features with no geometry carry no box. The guide now says so.

[github-actions]

Test gap. The PR body says "an added row gets one too", but this test only edits existing rows, so the added-row path has no coverage. The test also doesn't cover a removed row shrinking the collection box, a feature whose geometry is cleared, or the all-rows-removed case in the bug comment above. Add those, asserting refusal or an intended result. Confidence: high that the coverage is missing, low impact.

[Mavrick-F]

Added in 09af867: the test now publishes with a row removed (the collection box shrinks) and a row added (it gets its own box), and a separate test covers the all-rows-removed refusal.

[github-actions]

Nit, left for the release quality pass: the as_ binding is awkward (as is a keyword), and the doc on geojson (lines 9–18) still lists foreign members and CRS as the refused members without mentioning that bbox is now recomputed. Nothing here blocks the PR.

[Mavrick-F]

Left for the release quality pass: the as_ name and the geojson doc comment mentioning bbox.

Code review

I reviewed the 66-line change to crates/data/src/publish/json.rs and the docs note in docs/user-guide/index.md, checking the round-trip logic, the fixtures and the geometry writer. The main finding is one silent-loss path. Three inline comments are posted.

Bugs

• Source bbox dropped silently when no geometry is left (about 70% confidence). If the edit leaves no geometry to bound, total is None, so the collection bbox is omitted with no refusal or notice. The round trip doesn't catch it, because the edited document is compared with its own re-read. Reproduction: a fieldless layer with a collection bbox, every row deleted, then publish. A feature-level bbox on a row whose geometry becomes empty is dropped the same way. Inline suggestion posted.

Security

• None found. There is no unsafe, no new unwrap outside tests, and the recursion in extent runs over geometry written by RustGIS.

Performance

• None worth raising. extent adds one pass over coordinates inside the existing per-feature loop, which already checks Cancel.

Quality

• Test gap (high confidence the coverage is missing, low impact). The PR body says an added row gets a bbox, but the new test only edits existing rows. It also doesn't cover a removed row shrinking the collection box or the all-rows-removed case. Inline comment posted.
• Behaviour note (low confidence). feature_boxes is all-or-nothing. A source where only some features carry a bbox is refused, not handled. The refusal is safe and not silent, but the docs don't mention it.
• Nit, left for the release quality pass. The as_ binding name in grow is awkward, and the geojson doc comment (lines 9–18) doesn't mention that bbox is now recomputed. Inline comment posted with the quality-sweep marker.

AGENTS.md

• The change follows the never-crash and never-silent rules, except for the silent bbox drop above. Keep the new regression test and the refusal-table entry; both are good.
• The docs change matches the code's behaviour.

I left no earlier concerns out, because prior-reviews.json contains no threads.

preserves its own source `bbox` presence, while added, removed, or reordered
rows continue using the collection-wide `feature_boxes` policy. Add a regression
fixture with boxed and unboxed Point features; publishing must succeed and leave

Code review

Bugs: No correctness bugs found. I traced the recomputed boxes through the cases that matter: rows unchanged, rows added, removed or reordered, a geometry cleared, an all-empty collection, a top-level Feature, and nested GeometryCollections. Number spelling survives the verification pass because keep_numbers runs on both sides, so f64 vs integer Value equality doesn't cause a false refusal. Confidence: high.

Security: Nothing new. extent recurses only over geometry RustGIS built, so its depth is bounded. No unwrap, expect, indexing or unsafe in the non-test code. Confidence: high.

Performance: Minor. extent walks the geometry JSON that geometry_to_geojson just built. Computing the box from f.geometry would save a second pass per feature. Impact is negligible. Confidence: medium.

Quality:

• The reordered-rows path (rows_changed through ids, then the all-or-none box policy) has no test. The new tests cover edits, removals, additions and the refusals. Per AGENTS.md this is an extra test for working code, so it can wait for the release quality pass. Confidence: high.
• docs/user-guide/index.md lines 161–165 are wrapped unevenly; line 161 runs about 115 characters against about 100 elsewhere. Quality pass. Confidence: high.

AGENTS.md: No violations found. Errors go through refused(...), and the new tests cover both the clean and the refused cases. One point is already in the earlier threads: a feature whose geometry is cleared loses its bbox with no notice. The author's reply argues it isn't a loss and the guide now says so, so I left it alone. Confidence in no new violation: medium-high.

Already raised, left alone: 4 earlier concerns on this PR: the test gap for added and removed rows (answered and addressed), the as_ naming and the geojson doc comment (answered, quality pass), the silently dropped feature bbox when the geometry is cleared (answered), and the feature_boxes presence check (fixed and resolved). I posted no inline comments because I found nothing new worth one.

Left for the release quality pass: a test for the reordered-rows path, the guide paragraph's line wrapping, and computing the box from the geometry rather than its JSON.
