Part of the release quality sweep: the review points on analysis tools that were left for the release quality pass.

  • Points Along Lines guide: a line through one place twice gets a point there each time, except at a closed line's shared start and end, which gets one (review, comment).
  • Unsplit Line guide: each joined chain is its own output feature (a multipart input can become several), joins are decided among the selected features only, and two equal-attribute parts sharing both ends join into a closed line (1, 2, 3).
  • Stale comment in the point-count estimate: only a custom Inputs can give a repeated selection row, as a project's selection is normalized on load (review).
  • Buffer and Select By Location notices now say the outline edges were left unsplit, with no points added, keeping the count and the bounds (review, comment).
  • The near-pole radius search warning is formatted from network::REACH_STEPS_TOTAL, REACH_STEPS_MAX and REACH_STEP_DEG (now public) instead of repeating 250,000 steps and 512 degrees, with a test (1, 2).
  • Check Geometry guide: a ring with non-finite coordinates is reported for those and skips its other point checks (review).
  • Repair Geometry's summary and its assistant skill entry no longer promise every feature is made valid: features it can't repair are written unchanged, and those left with no area or usable points are written without geometry (review).
  • Kernel Density dropped a MultiPoint's non-finite members silently when its other members were used. They are now counted in one notice ("N point(s) with non-finite coordinates were left out of K multipoint feature(s) whose other points were used"), with a test for lossy and clean input (review).

Left out: nothing; every point in this group was handled.

Testing: cargo fmt --all and cargo test -p rustgis-analysis locally (all pass, including the new kernel_density_counts_a_multipoints_non_finite_members and the updated buffer notice test); the new bounded_warning_states_the_search_limits engine test, clippy with -D warnings, the full test suite, pre-commit and the wasm32 build ran in this pull request's CI, all green. Interface catalogs are not updated, per the usual practice; the changed strings show in English until the release translation pass.

Summary by CodeRabbit

  • New Features
    • Kernel Density reports non-finite points in multipoint features when other points are still used, while continuing to identify features with no usable points.
  • Documentation
    • Clarified how geometry repair handles missing or invalid coordinates and features it cannot repair.
    • Expanded guidance for Points Along Lines, Unsplit Line, and Check Geometry.
  • Improvements
    • Bounded-search warnings now display configured limits with digit-group separators.
    • Buffer and distance-selection messages clarify when outline edges remain unsplit.
    • Geometry repair descriptions clarify that unrepaired features are written unchanged, while features without usable geometry are written without geometry.

Say that a closed line's shared start and end gets one point in
Points Along Lines; that Unsplit Line writes each joined chain as its
own feature, joins among the selected features only and joins two
equal parts sharing both ends into a closed line; and that Check
Geometry skips a ring's other point checks when it has non-finite
coordinates.
The radius search's warning repeated 250,000 steps and 512 degrees by
hand. Make the analysis constants public and format the warning from
them, so the text follows if they change.
Kernel Density dropped a multipoint's non-finite members silently when
its other members were used. Count them and say so in one notice.

Also: Repair Geometry's summary and assistant skill entry say that
features it can't repair are written unchanged and those left with no
area or usable points without geometry; the Buffer and Select By
Location notices say outline edges were left unsplit; and a comment no
longer says a project can restore a repeated selection row.

Walkthrough

The changes expose network reach limits and use them in bounded-search warnings. Kernel Density now reports non-finite members omitted from partially usable multipoint features. Tool messages and geoprocessing descriptions clarify geometry outcomes and analysis behavior.

Changes: Reach limit reporting

Layer / File(s) Summary
Expose limits and report them in warnings
crates/analysis/src/network.rs, crates/engine/src/cmd/select.rs
The reach constants are public. Bounded-search warnings use the constants for their limits, format the step count with digit-group separators, and have a test for the warning content.

Kernel Density reporting

Layer / File(s) Summary
Count and report non-finite members
crates/analysis/src/tools.rs
Kernel Density separately counts non-finite members in multipoint features when other members are used. It adds a notice for those omissions. Tests check the counts and notice.

Geoprocessing messages and descriptions

Layer / File(s) Summary
Clarify tool messages and repair outcomes
crates/analysis/src/tools.rs, crates/assistant/skills/geoprocessing/SKILL.md
Repair Geometry, Buffer, and distance-selection descriptions clarify output outcomes. A comment updates the explanation of repeated selections, and a Buffer test checks the revised wording.
Document analysis behavior
docs/user-guide/analysis.md
The guide describes closed-line point handling, joins among selected features, closed-line output, and geometry checks for rings with non-finite coordinates.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Minimal · up to ea8dc

The reporting and documentation updates are mergeable after normal checks. A narrow clean-input test assertion remains worth improving, but no new runtime failure is established. The reported download failures were external HTTP 504 errors.

Full details: Title check

Explanation

The title "fix(analysis): release quality sweep" names the area (analysis) and the type of change (fix), but "release quality sweep" is broad. The PR covers many guide, message, and behavior fixes across analysis tools, plus a Kernel Density counting change and visibility change of constants. The title is partially related: it refers to a real aspect of the change without naming the main point. It is not vague in the sense of "misc updates" and it does not describe unrelated work.

Full details: Description check

Explanation

The description follows the repository template in part. It has a Summary section that lists the changes clearly and a Testing section that names commands and new tests. It has no UI evidence section, which is required. The author left the 'No visible UI change.' line unchanged, and that line appears in the template. However, the PR changes Repair Geometry text, Kernel Density notices, and Buffer and Select By Location notices. These are user-visible strings, but they are not map rendering or symbology. The template line therefore fits, so the UI evidence section is complete. The Related issue section is missing. It has a placeholder comment only and no issue reference, and the PR links review comments instead of an issue.

Resolution

Optionally add a Related issue entry, or state that no related issue exists. The description otherwise covers the template sections.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 2 files.

Code review

Bugs: None found. I checked each behaviour the PR's docs and summaries describe against the code on main, and all match:

  • Unsplit Line: joins are decided among selected rows only, each chain is its own output feature, and two equal-attribute parts sharing both ends form a closed line (crates/analysis/src/tools/geometry.rs:226). Confidence: high.
  • Points Along Lines: a closed line is walked as a ring, so its shared start and end get one point (crates/analysis/src/tools.rs:2679, test at :7281). Confidence: high.
  • Repair Geometry: Gone features are written without geometry and Kept features unchanged (crates/analysis/src/repair.rs, crates/analysis/src/tools/repair_geometry.rs:13). Confidence: high.
  • Check Geometry: non-finite coordinates are reported (crates/analysis/src/validity.rs). Confidence: medium-high. I read the polygon path only partway.
  • Kernel Density: non-finite MultiPoint members are counted in the new note, and Point losses are already in skipped. The test's expected counts (2 and 3 points) match the code. Confidence: high.
  • Pole warning: grouped(250_000) gives 250,000, and REACH_STEPS_MAX * REACH_STEP_DEG formats as 512. The notices_given and notices_since calls in the new test match their signatures. Confidence: high.
  • The size_output_points comment about selections normalized on load is backed by normalize_selection in crates/map/src/lib.rs:1015. Confidence: high.

Security: None found. The change adds no input handling beyond the non-finite counting.

Performance: None found.

Quality:

  • grouped() in crates/engine/src/cmd/select.rs:281 duplicates the public rustgis_map::graphics::thousands. Nit, confidence high. Posted inline; it can wait for the release quality pass.
  • docs/user-guide/analysis.md around line 247 has an uneven line break in the Points Along Lines paragraph ("one at A). Each point" ends a short line). Cosmetic only, not posted.

AGENTS.md: No violations found. The changed strings are plain format! messages, as the neighbouring analysis messages already are, and no unwrap, expect or panic was added to non-test code.

Not verified: I had no shell in this review, so I did not run cargo test, clippy or cargo xtask ci. The PR's testing claims are unconfirmed here.

Prior reviews: The thread list was empty, so there were no earlier concerns to skip.

otherwise, including when three selected parts share both endpoints, leave them
separate.

Code review

I checked the code behind each claim in the PR's doc and message changes, plus the new Kernel Density and warning code. Most claims hold. The one new concern is inline on docs/user-guide/analysis.md:984.

Bugs

  • No new bugs found. Checked the Unsplit Line rules (crates/analysis/src/tools/geometry.rs:226-312: per-chain output, selection-only joins via rows(), two-part closed-loop join), the Points Along closed-line rule (tools.rs walk_line / Spacing::placed), the Repair Geometry outcomes (repair.rs Gone/Kept, with notices in repair_geometry.rs), and the Kernel Density multipoint non-finite count (tools.rs:3672-3688). The code matches the new text. Low confidence (~30%): warn_bounded now formats REACH_STEPS_MAX * REACH_STEP_DEG as f64; it prints "512" today, which is correct.

Security

  • None found. Only numeric formatting and doc text changed; no new input paths.

Performance

  • None found.

Quality

  • docs/user-guide/analysis.md:461: the rewrap leaves "one at A). Each point" as a short orphan line before "has its feature's attributes". Markdown renders it fine. Confidence high. Left for the release quality pass.
  • select.rs grouped() duplicates an existing helper. Already raised in the prior review threads, so not repeated.

AGENTS.md

  • Never-silent: the new Kernel Density note and the reworded buffer/select notices each give one count per kind, and the tests cover both lossy and clean input. Compliant.
  • Never-crash: no unwrap/expect/panic added in non-test code. The new tests use unwrap_or/unwrap_or_default. Compliant.
  • Doc accuracy: the non-finite-ring sentence understates what is skipped. Posted inline (see Bugs/Quality above, and the inline comment on analysis.md:984). Confidence medium-high.

Prior reviews

  • 7 existing threads still apply to unchanged code, so I left them alone: the grouped duplicate, the Repair Geometry non-finite-hole exception, the unusable-multipoint skip count test, the mixed-multipoint projection-limit assertion, the skill's area condition, the hard-coded limits in the pole-warning test, and the three-part closed-line join rule.
  • Posted this run: 1 new inline comment.

- Repair Geometry's summary and the geoprocessing skill say that a
  non-finite coordinate anywhere, even in a hole, writes the feature
  without geometry, and that the area condition applies to polygons.
- The user guide says two parts sharing both endpoints join into one
  closed line only when no other considered part ends there.
- The pole warning uses rustgis_map::graphics::thousands instead of a
  duplicate grouping helper, and its test derives the limits from the
  reach constants.
- The kernel density multipoint test checks the skipped count of an
  all-non-finite multipoint and that no projection-limit note appears.

Code review

Bugs

  • Misleading Repair Geometry summary (medium-high). The new text in tools.rs:101 and SKILL.md:33 says features "it cannot repair are written unchanged". The code writes missing or non-finite geometry, and features with no usable points or no area, without geometry. Only too-complex or failed-repair features are kept as stored. Both are posted inline with suggestions.

Security

  • None found. The changes add no input handling, I/O, or command-ingress paths.

Performance

  • None found.

Quality

  • Analysis guide wrapping (docs/user-guide/analysis.md around lines 233–236). The Points Along Lines sentence was extended, but "Each point" was left dangling at the end of an over-long line. Reflow it. Left for the release quality pass.

AGENTS.md

  • No violations found. Silent-loss notices use one notice per kind with a count, and the Kernel Density change has both lossy and clean tests. Changed strings are not in the catalogs, which the guide allows.

Verified against code (no finding)

  • Repair Geometry: non-finite and no-area cases → Gone → written without geometry, matching the summary.
  • Unsplit Line doc: chains as separate features, selection-only joins, and closed two-part joins match tools/geometry.rs.
  • Pole warning: network is public, thousands is public in rustgis_map, and the Session test helpers exist.

Already raised (left alone)

  • 6 earlier threads were skipped because they were already raised or answered. The unresolved one is the analysis.md too_complex note. It says a non-finite ring "skips its other point checks", but validity.rs also skips its crossing and containment checks. That concern is still valid, but the text has not changed, so I did not re-post it.

Confidence: the two inline findings are medium-high. Everything else I checked is consistent with the diff.

Code review

Bugs

  • Buffer and Select By Location notice wording may be inaccurate (crates/analysis/src/tools.rs:1515, also :3325). The new text says the outline edges were "left unsplit, with no points added along them" and gives the point budget as the only cause. The halving limit (MAX_SPLITS = 12 in geodesic.rs) also sets the flag, and in that case points were already added along the outline. Reachable only for very long edges (over about 300 km). Confidence: medium-low (~50%). Posted inline.

Security

  • None found.

Performance

  • None found.

Quality

  • Nit, left for the release quality pass: the Points Along Lines paragraph in docs/user-guide/analysis.md (around lines 236–238) has an uneven hard wrap ("…one at A). Each point" ends a short line). Renders fine. Confidence: high.

AGENTS.md

  • None found. The new strings are plain format! notices. The analysis and engine crates don't use tl! or i18n::fmt anywhere, so the translation rule doesn't apply. rustgis_map::graphics::thousands and network are both public, so the select.rs change compiles against the pub constants.

What I checked against the code

  • Repair Geometry summary and SKILL.md: accurate. Non-finite coordinates anywhere, including hole rings, go to Gone::NonFinite (validity.rs ~585, repair.rs ~162). TooFewPoints and NoArea match the summary. Only Kept (too complex, or repair failed) is written unchanged.
  • Unsplit Line doc: accurate. Joins are limited to selected rows, need exactly two ends at a node, and a closed part joins nothing. Two open parts sharing both ends join into a closed line.
  • Points Along Lines closed-line sentence: accurate. A closed line gets one point at its shared start and end (for_each_line, and the points_along_lines_walks_a_closed_line_as_a_ring test).
  • Kernel Density multipoint notice: correct. Non-finite members are counted only when other members are used. An all-bad multipoint is counted as skipped, not as partial use. Lossy and clean inputs are both tested.
  • Selection-normalization comment: accurate. normalize_selection runs on project load (project.rs:930), so only a custom Inputs can repeat a row.
  • Pole warning: the new constants give the same text as before (250,000, 512°), and the test derives its expected values from the constants.

Prior review threads

  • I left alone the earlier concerns on the pole-warning test's independent expected value (answered as left for the release quality pass), the all-non-finite and mixed multipoint test cases, the Repair Geometry summary and skill contradictions, the non-finite ring doc, the closed-line doc qualifier, and the no-area guarantee. All are addressed in the current head or answered by the author.
  • Count: 11 earlier threads left alone. One new concern raised, on the buffer notice's causal wording, which no earlier thread covers.

- The Buffer and Select By Location notes for coarse outlines name both

  reaching its halving limit, instead of saying the edges were left
  unsplit with no points added.

Qualify which rings receive point checks.

A non-finite ring skips the repeated-vertex check, even when the feature is too_complex. The non_finite_coordinate row states this exception, but this row contradicts it.

Suggested fix

-| `too_complex` | Some of the feature's checks were left out: it needs more work than the tool spends on one feature, there wasn't enough memory to check it, or the geo library's relate operation failed on some of its rings or parts (`detail` says which of the three, not which rings or parts). The checks of each ring's points still run. The tool says how many features each reason left out |

Code review

Bugs: None found. I traced the changed logic against the code and found no defect:

  • Unsplit Line: joins are built only from selected rows, and two open parts with equal attributes that share both ends become one closed line. The documented behaviour matches crates/analysis/src/tools/geometry.rs:226.
  • Points Along Lines: a closed line's shared start and end get one point, which matches walk_line in tools.rs.
  • Kernel Density: the non-finite multipoint count is correct and the note is emitted once. Clean and lossy inputs both behave as the new test expects.
  • Repair Geometry: the new summary matches the Gone/Kept mapping in repair.rs.
  • Check Geometry: a ring with a non-finite coordinate is excluded from segments and containment, as the new doc says (validity.rs:585-614).
  • Pole warning: pub on the reach constants is valid (network is pub mod), and thousands is public.

I could not run cargo test or clippy here, so the test results in the PR body are unverified.

Security: None found. The changes are notices, docs and constants.

Performance: None found.

Quality:

  • The Repair Geometry intro in docs/user-guide/analysis.md:1008-1009 still says every feature is written "with its geometry made valid". Features are now written without geometry or unchanged, and the table below it says so. The sentence was already loose before this PR, so this is a wording point for the release quality pass. Confidence: high that it's imprecise, low severity. It is not on a changed line, so I did not post it inline.

AGENTS.md: No violations found. The new code has no unwrap, expect or panic. Each new notice goes through ToolResult::messages or Session::warn with a count. The Kernel Density change has a clean-input and a lossy-input test, as required. No std::time was added.

Prior reviews: 18 threads reviewed. I left 4 open threads alone because the code they point at has not changed and they are not answered: select.rs:529 (independent expected value, deferred to the quality pass), tools.rs:101 (precedence between "written without geometry" and "unchanged"; repair.rs checks Gone first, so the summary is still ambiguous), tools.rs:3325 (arc allowance in the notice), and tools.rs:8504 (test should assert both explanations). The other 14 were resolved or outdated and are addressed in the current code. No inline comments were posted.

Code review

Scope: 5 files, mostly the Repair Geometry summary, the Buffer and Select By Location notices, the Kernel Density multipoint notice, and the user guide. I found no bugs, security problems, or performance problems in the changed code. I could not compile or run the tests here (no shell), so the CI results in the PR body are unverified.

I checked the new text against the code it describes:

  • Repair Geometry summary and skill: repair.rs (gone() runs before kept()) and validity.rs (NonFinite is reported for hole rings and before the budget stop) match "written without geometry" for non-finite, null, too-few-points and no-area cases, and "unchanged" only for too-complex or failed repairs.
  • Unsplit Line guide: tools/geometry.rs only indexes selected rows, so an unselected part neither joins nor blocks. Two open parts sharing both ends close into one line, and a closed part's two ends block joins at its endpoint. Each chain is its own push_next, so the doc matches.
  • Points Along Lines guide: the closed-line test and the A-B-A-C test match the doc.
  • Kernel Density: the non-finite member count is correct, and the three test cases (lossy, all-bad, clean) cover both notice paths.
  • Pole warning: thousands is public in rustgis_map::graphics, and the constants are public in network.

Bugs: none found.

Security: none found.

Performance: none found.

Quality:

  • docs/user-guide/analysis.md:1060 (not in the diff, so I can't anchor an inline comment): "One the tool couldn't repair is written unchanged, never dropped:" contradicts the table directly below it, where the first four codes are written without geometry. This is the same contradiction the PR fixes in the tool summary and SKILL.md, and it was left in the guide. Suggested wording: "A feature the tool can't repair is written as the table says, never dropped:". Confidence: high (~85%) that it is inconsistent. The line predates this PR.
  • Nit, confidence high: the new sentence in analysis.md around lines 455–460 leaves a short line mid-paragraph ("one at A). Each point"). Cosmetic only, so it can wait for the release quality pass.

AGENTS.md: no violations in the changed code. No unwrap/expect/panic was added outside tests, the new Kernel Density notice is counted and tested both ways, and the notices go through ToolResult::messages or Session::warn. The old Repair Geometry summary string still sits in the i18n/*.tsv catalogs (for example az.tsv:4204). It is now orphaned, which AGENTS allows, so no action is needed.

Earlier review threads: there are 19 on this PR. I left all 19 alone. None of them is still open on code I found wrong, and I did not re-raise any.

No inline comments were posted, because I found nothing on a changed line that meets the bar.

…s the point or line it is

A hull with no area was written as a polygon whose ring has fewer than
the four positions one needs: GeoJSON wrote it invalid and a Shapefile
refused the layer. Points in one place now give that point, and points
on one straight line the segment between the two farthest apart (found
in two passes, the farthest from any point and then the farthest from
that). A Shapefile export of a layer with both leaves the points and
lines out and says how many. The error with nothing to hull also gives
the vertices passed over and the latitudes past a pole.

The ring closed on a NaN point (59ead33) gets a test in the data crate:
four vertices and edges, and deleting the first keeps it closed.

Merged main, which counts a multipoint's non-finite members in Kernel
Density (opengeos#1607); kept that, with a multipoint wholly beyond the system
counted as beyond only, and the error naming every cause.

Tests: single points and stacked points hull to a point, polar points on
one parallel to the line between the farthest two, and a hull with area
keeps a closed ring; the error's counts; the NaN-closed ring.

…they leave out (#1572)

* fix(analysis): Minimum Bounding Geometry counts what it hulls; Kernel Density counts the multipoint members it leaves out

Minimum Bounding Geometry, all features together, set its count field to
every feature in the layer, even with a selection or without geometry;
it's now the features hulled. Its notice of hulls with no area no longer
counts a hull of points in one place (a single point), which has none as
a matter of course.

Kernel Density left out a multipoint member missing a coordinate (or
with an infinite one), in a feature with others, silently. It now says
how many in a notice of its own, and in the error when nothing is left
to place. A multipoint wholly past what the system can hold counts its
points as beyond, as a point does, and no longer as skipped too.

Tests: count with and without a selection, a feature without geometry
not counted; single points give no notice; members left out are
counted, clean multipoints say nothing, and the error names both.

* fix(analysis): Minimum Bounding Geometry passes over a missing coordinate instead of failing (#1556)

A vertex with a coordinate missing or infinite made the hull panic (its
ordering can't compare a NaN), so the tool failed for the whole layer.
It's now passed over and counted. A feature without geometry, left out
silently one feature each, is counted too, and with nothing at all to
enclose, all together, the tool says so as an error rather than writing
an empty hull. The no-area notice counts any hull of two points or more
again, stacked ones included; only a single point's is left out. Kernel
Density's error with nothing to place also says how many features it
skipped.

Tests: missing coordinates and a feature without geometry are counted,
all together and one feature each, and clean points say nothing; the
error with nothing to enclose; stacked points give the no-area notice.

* fix(analysis): Minimum Bounding Geometry passes over far-out vertices and writes no hull for a feature with no usable point

A vertex so far out (a longitude in the millions of degrees) that the
hull's products of differences overflow could still make it panic; it's
passed over and counted like a missing coordinate. One feature each, a
feature with no point the hull can use got an empty polygon; it's now
skipped and counted with those without geometry. The no-area notice
counts a single point's hull again and names it, and count holds each
row once however often a selection lists it.

Tests: a far-out vertex is passed over (the hull fails without the
limit), no hull is written for a feature with no usable point, single
points give the notice, and a row listed twice counts once.

* fix(analysis): Minimum Bounding Geometry takes each picked row once and writes no hull with nothing to enclose

A row a selection lists twice was counted twice in the skipped and
passed-over notices, and hulled twice one feature each; the rows are
taken once. A closed ring's repeated last point no longer counts a bad
vertex twice. All together with nothing to enclose now writes no hull
and says why, as one feature each does, rather than failing the run.
The passed-over notice says what it catches (a longitude far out of
range; a latitude past ±90° is the pole, as the analysis plane takes
it), and the user guide describes the tool.

Tests: nothing to enclose gives no hull either way, with the skipped
count; a far-out vertex in a closed ring counts once.

* fix(analysis): Minimum Bounding Geometry keeps the selection's order while taking each row once

Dropping repeated rows by sorting them put the hulls, one feature each,
in the layer's order instead of the selection's. Repeats are now dropped
as they come. Test: a selection of rows 2, 0, 2 gives the hulls of 2
and 0, in that order.

* fix(analysis): Minimum Bounding Geometry errors when nothing hulls

With every feature skipped, it returned an empty layer; it now returns
an error saying how many features had no point to hull, as Kernel
Density does for an unusable result.

A latitude past a pole is taken as that pole, as Points Along Lines
takes it, and the notice now says how many such vertices were found.

The passed-over notice names only what its limit catches: a coordinate
missing or infinite, or far beyond about 9 million degrees.

A ring that repeats a NaN start point as its end counts that vertex
once: the closing point is matched by its bits, as NaN equals nothing
as a number.

* fix(analysis): Minimum Bounding Geometry writes a hull with no area as the point or line it is

A hull with no area was written as a polygon whose ring has fewer than
the four positions one needs: GeoJSON wrote it invalid and a Shapefile
refused the layer. Points in one place now give that point, and points
on one straight line the segment between the two farthest apart (found
in two passes, the farthest from any point and then the farthest from
that). A Shapefile export of a layer with both leaves the points and
lines out and says how many. The error with nothing to hull also gives
the vertices passed over and the latitudes past a pole.

The ring closed on a NaN point (59ead33) gets a test in the data crate:
four vertices and edges, and deleting the first keeps it closed.

Merged main, which counts a multipoint's non-finite members in Kernel
Density (#1607); kept that, with a multipoint wholly beyond the system
counted as beyond only, and the error naming every cause.

Tests: single points and stacked points hull to a point, polar points on
one parallel to the line between the farthest two, and a hull with area
keeps a closed ring; the error's counts; the NaN-closed ring.

* fix(analysis): Minimum Bounding Geometry's layer type follows its hulls; a ring's NaN closing point matches with a signed zero

With hulls with no area written as points or lines, a layer of only
points was still declared a polygon layer, so point tools such as
Kernel Density refused it. The layer is now a point layer when every
hull is a point and a line layer when every hull is a line; a mix stays
a polygon layer. A hull that somehow has no ring is counted as skipped
rather than written without a geometry. The comment on the far-out
limit no longer says it guards against overflow, which only starts
near 1e154 m; it's a conservative cut past any real data.

A ring's closing point is matched coordinate by coordinate, equal as
numbers or a NaN by its bits, so a NaN endpoint written once with 0
and once with -0 still closes the ring.

Tests: the layer's type for points, lines and a mix; a feature whose
only point is missing a coordinate isn't counted; the signed-zero ring.

* fix(data): a GeoPackage export leaves out geometry of another kind than the layer's, and says how many

A layer can hold geometry of more than one kind: a GeoJSON of points and
polygons, or Minimum Bounding Geometry's hulls, where a hull with no area
is a point or line among polygons. A GeoPackage export declared the
column as the layer's kind (MULTIPOLYGON) and wrote the points into it,
breaking the column's contract, silently. A feature of another kind is
now left out and counted in the export's notice, as a Shapefile leaves
it out; a feature without geometry still goes in, as a table holds it.

The user guide says what a mixed hull layer holds and how it exports.

Tests: a GeoPackage of a polygon, a point and a feature without
geometry holds the polygon and the feature without geometry (checked
with SQL), the point counted as left out; a layer of one kind loses
nothing. A ring closed on a NaN point with the signed zero in x.

* fix(data): a streamed GeoPackage export leaves out geometry of another kind too, and none is copied

The kind filter ran only on a layer held whole: a streamed export (a
large GeoParquet, say) wrote a point into a polygon column, silently.
Each chunk now goes through the same filter, and its count is reported.
The filter hands the writer the runs of features the table can hold,
borrowed from the layer, so a large layer with one point among its
polygons isn't copied; only an export to be projected copies it, as
projecting already did, and it filters first, so a feature the system
can't place no longer fails the export when it would be left out anyway.

The export notice now says why features were left out: "no drawable
geometry, or a geometry of another kind than the layer's".

Tests: a streamed export of squares with points among them, a few
features a chunk, matches the whole export and counts the points; a
projected export leaves out a point UTM zone 18N can't place (it failed
before) and writes the polygon.

* fix(data): a GeoPackage export of a layer with no declared type keeps its geometry

A layer that declares no geometry type but carries geometry was written,
whole, as a table with no geometry column, dropping every geometry with
no notice, while a streamed export took its first geometry's kind. The
whole export now takes that kind too, and leaves out and counts the
geometry of other kinds, borrowing the features as before.

Tests: such a layer exports a MULTIPOLYGON table with its point left out
and counted, and its streamed and whole exports give the same table.

* fix(data): a projected GeoPackage export leaves out off-kind features before projecting, on both paths, with one copy

A streamed GeoPackage export projected each chunk before leaving out the
features of another kind, so one the system couldn't place failed the
export where the whole export wrote the rest. Each chunk is now trimmed
first; its features are its own, so nothing more is copied. A whole
projected export copies the layer once (it copied it twice: once to
leave features out, again to project), and a layer with no declared
type keeps the count of what it left out before the projection. The
scan for off-kind features stops on a cancel.

Tests: a streamed export to UTM zone 31N with points on the other side
of the world writes the squares and counts the points, as the whole
export does; a projected export of a typeless layer keeps its count.

* fix(data): no unused variable in the browser build of the streamed export

The GeoPackage kind check is desktop-only; its flag was also defined, unused, for wasm32, which CI builds with warnings as errors.

* fix(data): a GeoPackage export of a mixed layer keeps every feature in a GEOMETRY column

The export had started leaving out geometry of another kind than the layer's
declared type. Readers declare a layer by its most common kind (or, streamed,
its first geometry's), so an ordinary GeoJSON or KML of points and polygons
lost its minority kind on GeoPackage export, where it used to be written.
GeoPackage allows a GEOMETRY column, so a mixed layer now gets one: the whole
export decides up front, and a streamed or added table starts again with it
when it meets another kind (Redo::Mixed), as it does for multipoints.

The left-out notice is worded per format (io::left_out_note): a Shapefile
names both reasons it drops a feature; FlatGeobuf, KML and GPX only lack
geometry.

Minimum Bounding Geometry says when its output is a point or line layer, or
where flat hulls go in a polygon layer. Dissolve counts the features it left
out for having no polygon (it skipped them silently), and errors when none
has one.

* fix(analysis): Dissolve leaves out empty polygons too; the Shapefile notice says what the export left out

An empty polygon in a Dissolve group added nothing to the union but
counted in the group's count and statistics, and escaped the notice. It
is now left out and counted with the features that have no polygon.

The Shapefile left-out notice described the format ("can't hold"),
though a Shapefile can hold a null shape; it now says what the export
left out: "N features left out of the Shapefile: without drawable
geometry, or with geometry of another kind than the layer's".

Tests: a group's count and SUM leave out a point and an empty polygon
among its polygons; a Shapefile export of a polygon layer with a point
and a feature without geometry counts both and writes the polygon; a
multipoint in a mixed GeoPackage export comes back with both members,
streamed and whole.
