Part of the release quality sweep: review points on the geometry, render, map and engine code left for the release quality pass.
MGRS: parse_mgrs judges the zone (1 to 60) before the band letter, as parse_utm does, so 0AAA and 61AVE report the bad zone instead of an unsupported polar reference; two rows added to invalid_mgrs_is_refused (review).
POLE_TOLERANCE's doc no longer says only the tests use it: it names the engine's polar edits and analysis's topology, conversion and network code (review, comment, comment).
Canvas::place clips a pixel child to clip through a mask, as the recorded branch does, with a test that pixels outside the clip stay empty (review).
render_frame records vectors only when no colour-vision simulation applies, so vectors can't skip it (review).
The Print Map PDF has its own overflow notice ("The map is drawn as one picture, not vectors: its vectors would pass N MB") instead of the layout one about pages (comment).
A connection parameter that isn't text gets "connection must be a saved web-service connection id (text)", and an unknown id in a web request reads as NO_SUCH_CONNECTION (comment).
stac.addAsset warns when the asset's metadata names je:rastersdn.error codes for a failed retrieval (or names them in a way that can't be read whole), since a single file draws them as values; a regression test checks the coded asset gives the notice and a clean one none (comment).
The EPSG:5880 test comment now says x is the false easting itself and the million-odd metre offset is in the northing (review).
Left out: nothing.
Testing: cargo fmt --all; cargo clippy -p rustgis-geom -p rustgis-render -p rustgis-map -p rustgis-engine --all-targets -- -D warnings; cargo test -p rustgis-geom -p rustgis-map -p rustgis-render (all pass); the engine suite ran in CI (Test (ubuntu-latest) passed), along with lint, clippy and the wasm32 web build.
Summary by CodeRabbit
Bug Fixes
Map rendering now respects clipping boundaries, including for translated content.
Invalid MGRS zones are reported as zone errors. Connection errors more clearly identify invalid values and missing saved connections.
STAC asset imports provide notices when metadata codes are unreadable or contain invalid values.
When vector drawing exceeds PDF limits, the map is rendered as a picture and the warning reports the applicable limit.
Rendering now uses pixels when needed to preserve view effects and color-vision settings.
Documentation
Clarified how polar tolerances are used in mapping and analysis.
parse_mgrs now refuses a zone outside 1 to 60 before reading the band
letter, as parse_utm does, so 0AAA and 61AVE report the bad zone rather
than an unsupported polar reference.
POLE_TOLERANCE's doc said only the tests use it; the engine's polar
edits and analysis's topology, conversion and network code do. The
EPSG:5880 test comment now says the million-odd metre offset is in the
northing, not the easting.
Canvas::place drew a pixel child without its clip, though the
recording branch clips and the doc promises it: the pixel branch now
draws through a mask of the clip.
render_frame records vectors only when no colour-vision simulation
applies, so a change to the full-resolution rule can't let vectors
skip the simulation.
stac.addAsset now warns when the asset's metadata names codes for a
failed retrieval (JAXA Earth's je:rasters dn.error), which a single
file draws as values; a data cube already skipped them.
The Print Map PDF's overflow notice spoke of pages; it now says the map
is drawn as one picture. A connection parameter that isn't text gets
an error saying what it must be, and an unknown id in a web request
reads as NO_SUCH_CONNECTION.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The changes update PDF and STAC notices, standardize connection errors, validate MGRS zones, revise geospatial comments, apply clips during pixel placement, and select pixel rendering for color-vision simulation.
Changes: Command notices
Layer / File(s)
Summary
PDF overflow notice crates/engine/src/cmd/share.rs, crates/engine/src/tests.rs
When PDF drawing overflows, the warning reports vector drawing limits. The fallback no longer calls pictured_notices. Tests check the notices and PDF content.
add_asset checks invalid-value metadata and warns when codes are unreadable or present. Tests check notices for absent, numeric, and nonnumeric metadata.
request_params and named use shared errors for non-text connection values and missing or non-service connection IDs. The UI localizes the non-text error.
Geospatial updates
Layer / File(s)
Summary
MGRS validation and geospatial references crates/geom/src/utm.rs, crates/engine/src/cmd/search.rs, crates/geom/src/lib.rs, crates/map/src/projection.rs
parse_mgrs checks that zones are in the range 1–60 before checking the band. Tests expect zone errors for invalid zones. Comments clarify POLE_TOLERANCE usage and the EPSG:5880 expected coordinate.
Rendering updates
Layer / File(s)
Summary
Clip pixel placement crates/render/src/canvas.rs
Canvas::place applies an optional clip when placing pixels. Tests cover identity and translated clips.
The changes are mergeable with bounded follow-up for misleading STAC notices, untranslated connection notices, large-layout export overhead, and test coverage. Failed PNG rendering no longer emits the PDF picture notice.

Full details: Title check
Explanation
The title names three crates (geom, render, engine) and says 'release quality sweep', which matches the author's stated purpose. It does not name the specific changes. The changeset covers many unrelated review fixes, such as MGRS zone validation, POLE_TOLERANCE docs, Canvas::place clipping, render_frame vector gating, PDF overflow notice, connection errors, stac.addAsset warnings, and an EPSG:5880 comment. The title is therefore broad but related to the changeset, and it does not describe anything absent from it. The vague term 'sweep' is the main weakness.
Full details: Description check
Explanation
The description follows the template in part. It has a Summary section with a clear list of changes and a Testing section with commands and CI results. It has no UI evidence section, even though the template requires one. The changes include visible behavior, such as a new Print Map PDF overflow notice, a new connection error message, and a new stac.addAsset warning, so the author should state whether those count as visible UI changes. The 'Related issue' section is empty. The template asks for a line such as 'Closes #123' or 'Part of #456'. The author's text starts with 'Part of the release quality sweep', but it does not link an issue. The description also states 'Left out: nothing.', which does not add useful information.
Resolution
Add the '## UI evidence' section. State whether the PDF overflow notice, the connection error text, and the stac.addAsset warning are visible UI changes. If they are, attach before and after screenshots. If they are not, keep the line 'No visible UI change.' Fill in the '## Related issue' section with an issue reference, or state that no issue exists. Remove the 'Left out: nothing.' line or replace it with useful content.
Full details: Docstring Coverage
Explanation
Docstring coverage is 50.00% which is insufficient. 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 10 functions across 9 files. (1 skipped: 1 too large.)

Test coverage (AGENTS: "Test both ways"). The Print Map PDF now emits its own overflow notice here, replacing the layout one, but I found no test that asserts this notice's text or that a clean map export gives none. Please add a test next to the existing map PDF tests, using rustgis_render::vector::TEST_MAX_COST (or the equivalent test hook) to force an overflow, that checks the notice is given once and that an export under the limit gives no such notice.
The reason will be displayed to describe this comment to others. Learn more.
The clean side is now covered in 97bf083 (the_map_pdf_keeps_vectors_and_says_nothing_with_or_without_colour_vision: no picture, no notice). Forcing the overflow side from the engine needs render's TEST_MAX_COST, which is test-only inside rustgis-render and not reachable from engine tests; exposing a cross-crate test hook for this one notice is left for the release quality pass.
Reviewed the whole diff (9 files) against the base, checking the new APIs and call sites it relies on. I could not build or run the tests here, so compile and test results are unverified.
Bugs: None found. Checked the canvas clip mask (it is in the canvas's space, as the docs say), the MGRS zone reorder (only the error kind changes; no valid input is affected), the connection error paths (no remaining references to the old messages), the codes_unread path (a clean asset gets Some(Vec::new()), so it does not warn falsely), the serve_routes{base} substitution, and the POLE_TOLERANCE doc (design.rs, topology, convert and network all use it). Confidence: high.
Security: None found. The new code adds no input parsing beyond the existing pick/asset_href path.
Performance: The clip path allocates a canvas-sized Mask for each clipped pixel child. That is fine for the current call sites. Confidence: low, not worth a change now.
Quality:
Test coverage gap: the new Print Map PDF overflow notice (share.rs:194) has no test for either the lossy or the clean case. Posted inline. Confidence: high.
stac.rs:255: i.pick(...).ok().map(...).unwrap_or_default() would hide a pick error. asset_href selects the same key, so the failure is probably unreachable, but ? would be more honest. Confidence: low.
stac.rs:266: the unreadable-codes notice has no count, unlike the other stac notice. Confidence: low.
share.rs:193: MAX_COST >> 20 is the threshold (256 MiB native, 64 MiB wasm), not an estimate of the vector size. The wording matches the layout notice, so it is consistent. Confidence: low.
AGENTS.md: No violations found in the changed lines. No unwrap, expect, panic or unsafe in non-test code. The new engine test uses unwrap, which is allowed in test code. No std::time. The layer boundaries hold. The one rule gap is the untested notice above.
Prior reviews: No prior threads existed, so none were left out.
Not verified: Whether rustgis-engine tests pass. The PR body says the result is "in the comment below", but no such comment appears in the metadata. The new engine test expects exactly 4 HTTP requests; if add_url makes more, the test would fail.

Included review availability: This review used your included allowance. Your plan provides up to 8 included reviews per hour; 4 remain after this review.
I read the full diff, the base-branch AGENTS.md, and the 10 existing review threads. I checked the MGRS zone ordering, the STAC retrieval-code path, the canvas clip mask, the POLE_TOLERANCE doc references, the EPSG:5880 comment and the colour-vision export path. I posted one new inline comment and left the rest to the existing threads.
Bugs
Colour-vision PDF exports are silently rasterised (new, inline on share.rs:191), confidence 0.75. The render_frame gate stops vector recording when color_vision != Normal. Exports never apply the simulation (lib.rs:4483), so the gate removes vectors without changing any colour. The overflow notice does not fire for this case.
Security
None found in the changed lines.
Performance
None new. The full-canvas mask allocation in Canvas::place is already raised in an existing thread.
Quality
service_logins.rsnamed: the error for an unknown connection id no longer points to connection.list. The new NO_SUCH_CONNECTION text is less helpful. Low confidence on impact, 0.4.
New engine notices in share.rs and stac.rs are plain English with no translation mapping. This matches the existing engine notices, so I flag it only as context for the translation thread.
AGENTS.md
The PR body's rationale for the render_frame change conflicts with lib.rs:4483 (see the inline comment above).
Verified as correct: pictured_notices is still used elsewhere (no dead code), POLE_TOLERANCE references in the doc resolve to real call sites, the EPSG:5880 comment matches the central-meridian geometry, and the MGRS zone check keeps 75 Main St as a syntax error.
Already raised, left alone: 10 concerns
The threads on share.rs:194 (two: test coverage and the drawing-limit wording), stac.rs:255 (trimmed asset key), stac.rs:276 (long notice with 32 codes), service_logins.rs:50 (translation mapping), tests.rs:15992 (unreadable-code test), utm.rs:984 (search propagation test), canvas.rs:249 (mask allocation), canvas.rs:419 (transform test) and lib.rs:3169 (colour-vision gate). I checked lib.rs:4483 and it supports the lib.rs:3169 thread.
Change size
Compared: the whole PR against main (merge base df28c6c to PR head 85e5402).
- render_frame keeps recording an export with a colour-vision view:
exports never simulate colour vision, so the gate only applies on
screen; a test checks the Print Map PDF stays vectors with no
notice, with and without colour vision.
- The Print Map PDF's picture notice names the drawing limit (size or
item count) rather than only vector size.
- stac.addAsset reads the retrieval codes of the asset picked by the
same selector, lists at most five (large ones in exponent form), and
a test covers codes that can't be read whole.
- CONNECTION_TEXT is translated in connectionui::translated.
- search tests check a bad MGRS zone (0AAA, 61AVE) reaches the result.
- A Canvas::place test with separate clip and child transforms.

Re-raising the earlier test-coverage point, because the code here has changed but the gap remains. The new overflow notice has a clean-input test (the_map_pdf_keeps_vectors_and_says_nothing_with_or_without_colour_vision), but nothing forces an overflow and checks that this notice is given once. That is the lossy half of "Test both ways".
What is new: the earlier suggestion to use rustgis_render::vector::TEST_MAX_COST will not compile from the engine crate. It is declared pub(crate) under #[cfg(test)] in crates/render/src/vector.rs, so only render's own tests can set it. Options: expose a #[doc(hidden)] setter for it behind a test-only feature, or cover the overflow notice from a render-side test that calls into the engine path. Either way, the test should assert the notice text appears exactly once when the drawing overflows.
The reason will be displayed to describe this comment to others. Learn more.
Agreed the overflow half is untested; the options named (a doc-hidden setter behind a test-only feature on rustgis-render) add a cross-crate test hook for one notice, which is a test-infrastructure change rather than a fix. Left for the release quality pass.
Bugs: No new bugs found. I checked the render gate change against the export path: colour vision is applied only through vision at crates/render/src/lib.rs:4483, which is Normal for full_res_rasters, so recording exports with a colour-vision view is correct. The Canvas::place clip uses the same space as the recorded branch. The MGRS zone check matches parse_utm. The STAC notice selector is consistent between asset_href and pick.
Security: None found.
Performance: No new issues. The full-page Mask allocation in Canvas::place (crates/render/src/canvas.rs:247) is still there, but that concern is already raised and unchanged (see below).
Quality:
Low confidence: request_params and named in service_logins.rs no longer point users to connection.list when an id is unknown. This is a minor UX loss, left for the release quality pass.
AGENTS.md:
Medium-high confidence: the Print Map overflow notice (share.rs:332) has no lossy-case test, which breaks "Test both ways". Posted inline. The suggested TEST_MAX_COST hook is pub(crate) in render and cannot be used from engine tests.
Prior review threads: 11 threads were in the file. I re-raised one (the share.rs overflow-test thread, outdated, with the new hook detail). I left alone 8 that are answered or addressed by the code: stac.rs notice length (now capped at 5), unread-code test, invalid-zone search test, canvas clip-transform test, the pictured_notices text, the stac selector thread (both lookups use the same selector), the translation mapping, and the resolved colour-vision thread. I left alone 1 that is still open and unchanged: the canvas mask allocation (canvas.rs:249).
Checks run: none. There is no shell in this review, so I relied on reading the diff and the surrounding source. The claim that CI passed comes from the PR body and was not verified here.

- Around line 332-334: Move the s.warn call for the vector drawing limit notice
until after PNG rendering and decoding both succeed. Preserve the existing
warning condition and message, and ensure rendering or decoding failures do not

- Around line 332-334: Add a Print Map PDF overflow test that drives the drawing
beyond its budget and verifies both that the warning is emitted and that the
output uses the full-page picture fallback instead of an incomplete vector
drawing. Locate the warning in the map-sharing flow around the visible `s.warn`
call and exercise that behavior through the relevant PDF generation path.
Review comments at @crates/engine/src/cmd/stac.rs:
- Around line 269-280: Condition the `s.warn` call in the `invalid`-code branch
on the added asset being a raster, so non-raster assets with `je:rasters` codes

warning appears for raster assets and is omitted for non-raster assets.
Review comments at @crates/engine/src/tests.rs:
- Around line 16014-16016: The PDF assertions in this test can pass for a blank
page; inspect the decompressed page content and assert that it contains
representative map features in both colour-vision modes. Keep the existing
checks that the map is rendered as vectors and that no picture notice is
present.
- Around line 15991-15993: Extend the asset notice test around `stac.addAsset`
with a multi-asset fixture containing one clean asset and one coded asset.
Explicitly select each asset and assert that the clean selection receives no
warning from the coded asset while the coded selection receives its expected
notice, so the test verifies that metadata selection honors the selected asset.
Review comments at @crates/render/src/canvas.rs:
- Around line 411-419: Add a clip test alongside the existing pixel-placement
tests that uses nested contours oriented in the same direction and the even-odd
fill rule. Assert that a pixel inside the inner contour remains transparent,
ensuring clipping respects even-odd semantics rather than hard-coding winding.
- Around line 411-419: Update the clipping tests around `Clip` and `c.place` to
include a fractional or diagonal clip edge and assert that a pixel on that
boundary has partial alpha. Keep the existing inside/outside assertions, and
choose a boundary sample that verifies antialiasing rather than a fully covered
or transparent pixel.
- Line 416: The new clipped-placement tests only exercise full opacity; add a
case using fractional opacity in the canvas placement test around c.place, with
a clip, and assert the expected alpha both inside and outside the clip. Reuse
the existing point-swatch layout coverage rather than adding another
point-swatch case.
- Around line 408-419: Add a separate clipping test alongside the tests using
`Canvas::new` and `c.place` that fills the destination with a nontransparent
background before placing the clipped child. Assert pixels outside the clip
retain their original background color, while preserving coverage of the clipped
placement behavior.
- Around line 408-409: Add a test alongside the existing child-clipping tests
that places a pixel-only child on a recording canvas using a clip, flushes the
recording through the existing drawing/replay flow, and verifies pixels inside
the clip are rendered while pixels outside remain transparent. Use the Canvas,
place, and replay APIs visible in the diff, keeping the test focused on
recording-parent clipping.
Review comments at @crates/render/src/lib.rs:
- Line 3169: Add a focused test for `render_cpu` with `record=true`,
`full_res_rasters=false`, and a non-Normal `ColorVision` simulation; assert that
`recorded` is `None` and the rendered pixels reflect the simulation rather than
Normal color vision, so the test fails if this guard is removed.
Review comments at @crates/ui-egui/src/connectionui.rs:
- Line 92: Update the notice display path in connectionui to pass the queued
error through connectionui::translated before showing it in the status bar or
toast; keep the engine’s raw error handling and command_failed flow unchanged.

Reviewed the full diff against pr-context/AGENTS.md, the prior threads, and the surrounding source (canvas.rs, render/lib.rs, layout.rs, tiles/stac.rs, geom/utm.rs, engine tests). I could not build or run the tests in this environment, so everything below was checked by reading.
Bugs
Medium confidence (~0.6), posted inline on crates/engine/src/cmd/stac.rs:266: an asset whose je:rasters.dn.error is null or a non-list sets codes_unread, so stac.addAsset says the metadata "marks failed retrievals" and that the map "draws them as values". No codes are named, so this is a false notice on clean input. Fix direction is in the comment. Correction to that comment: I cited test line 16006, which I did not verify. The test to cover this is a_stac_asset_with_retrieval_codes_says_they_draw_as_values in crates/engine/src/tests.rs.
Security
None found.
Performance
High confidence, already raised:Canvas::place (crates/render/src/canvas.rs:247) allocates a full-page Mask on every clipped pixel placement, which is a real cost on large PNG layouts. The thread at canvas.rs:249 covers it and the maintainer deferred it. Not re-posted.
Quality
Low confidence:canvas.rs:247let Some(mut m) = Mask::new(...) else { return }; drops the child without a notice. It is unreachable for a non-empty pixmap, so this is a nit.
Low confidence:named() in service_logins.rs lost the "(connection.list)" pointer when its error text changed to NO_SUCH_CONNECTION. Users no longer get a hint where to look.
AGENTS.md
Low confidence: the two new user-visible notices in share.rs and stac.rs are plain English, while CONNECTION_TEXT is mapped through connectionui::translated. The engine has no i18n use at all, so this follows the existing engine convention; flagging only for consistency.
PR description is out of date: it says render_frame "records vectors only when no colour-vision simulation applies". After 97bf083 it records exports with a colour-vision view, as render/lib.rs:3165-3169 now shows. The description should be corrected.
Checked and found correct
The Canvas::place clip is applied in the same space as the recording branch. Both layout callers (layout.rs:251, 1885) pass clips in the parent's space.
The render_frame gate is consistent with the export override at lib.rs:4483, and every recording caller goes through complete(.., true), which passes full_res_rasters = true.
The parse_mgrs zone-first reorder cannot misreport a zone-less UPS reference, because zone_and_letter already requires zone digits.
The POLE_TOLERANCE doc names callers that exist. MAX_ITEMS / 1_000_000 yields 20 for the current constant.
The Print Map overflow notice is emitted after the PNG is decoded, and it does not replace any other notice from pictured_notices.
Left alone: 14 open prior threads that the code still matches (canvas.rs mask bound, overflow and PDF-content test gaps, unknown-band MGRS cases, raster-only STAC notice, multi-asset fixture, and extra canvas and render tests). Resolved threads were not re-checked.
Change size
Compared: the whole PR against main (merge base bbaad9c to PR head b4def78).
- stac.addAsset's notice for codes that can't be read says what was
wrong (the dn.error field isn't a list of numbers, or has too many)
and that any such codes in the file draw as values, rather than
claiming the metadata names codes.

Low confidence, quality/never-silent: else { return } drops the child with no trace if the mask can't be made. I don't think this is reachable today: self.pm already exists at this size, and I expect tiny-skia's Mask::new to accept any size Pixmap::new does (I did not check tiny-skia's source here). If that holds, state the invariant in a comment so a future size change doesn't silently hide the placed picture. This is a small point; it can wait for the release quality pass.

Not reachable: the mask is made at the size of a pixmap that already exists, and tiny-skia's Mask::new accepts the sizes Pixmap::new does. Stating the invariant in a comment is left for the release quality pass.
I found no bugs, security issues, or AGENTS.md violations in the changed code. I checked the clip and mask handling in Canvas::place against the recorded branch, the colour-vision gate in render_frame (exports pass full_res_rasters, so the simulation never runs on that path), the MGRS zone ordering (the zone is capped at two digits, so u8 can't overflow), the STAC codes_unread semantics, the engine notice path (Session::warn), and the test helpers. Engine code has no tl! calls, so the new English engine notices follow the existing convention. The crate's unwrap deny is exempted for tests by clippy.toml.
Bugs: none found.
Security: none found.
Performance: none new. The full-page mask allocated per clipped pixel placement was already raised and deferred (see below).
Quality
crates/render/src/canvas.rs:247: let Some(mut m) = Mask::new(..) else { return }; drops the child without a notice if the mask can't be made. It looks unreachable, since the pixmap already exists at that size. Posted inline as low confidence, with a suggestion to document the invariant (about 60% confidence it can't trigger).
crates/engine/src/cmd/share.rs:334: the notice says MB, but >> 20 gives MiB. MAX_ITEMS / 1_000_000 also truncates if the constant ever stops being a whole number of millions. Both are cosmetic (high confidence, low impact).
crates/engine/src/service_logins.rs:801-810: named no longer points users to connection.list when the id is unknown or not a service. This is a small loss of guidance (high confidence, low impact).
AGENTS.md: no violations. The new notices are English engine text, which matches the existing engine convention. The new strings don't need catalog entries.
Earlier concerns: I left 13 open threads alone because they were already raised and the code they point at hasn't changed: the per-placement full-page mask, the overflow notice test, the unknown-band MGRS cases, the raster-only STAC notice, the multi-asset STAC fixture, the PDF content check, the recording-parent canvas test, the existing-background canvas test, the even-odd and antialiasing canvas tests, the fractional-opacity test, the render_cpu direct test, translating engine errors in the UI, and the failed-picture fallback test. Resolved threads were checked and are answered in the code.

Inline comments:
Review comments at @crates/engine/src/cmd/stac.rs:
- Line 267: Update the warning in the retrieval-code handling in stac.rs to say
the map may draw unreadable failure codes as values, rather than asserting that
all such codes are drawn; preserve the existing warning context.
Review comments at @crates/engine/src/tests.rs:
- Line 15999: Update the clean-input assertion in the test using `said` to
reject the shared phrase “failed retrieval” rather than only “failed
retrievals,” so it catches either retrieval-code warning.
- Line 15999: Update the raster notice assertion using the `said` collection to
verify that the unreadable-asset explanation also conveys that unmasked codes
may be drawn as values. Check for that meaning without requiring the current
unconditional wording.

Failed pre-merge checks:
- Description check:
Add the '## UI evidence' section. State whether the PDF overflow notice, the
connection error text, and the stac.addAsset warning are visible UI changes. If
they are, attach before and after screenshots. If they are not, keep the line
'No visible UI change.' Fill in the '## Related issue' section with an issue
reference, or state that no issue exists. Remove the 'Left out: nothing.' line
or replace it with useful content.

Nothing new cleared the bar for an inline comment, so this review posts none. I checked the diff against the base branch and the repo's AGENTS.md. The 28 existing threads on this PR are left alone. Most were answered by a maintainer as deferred to the release quality pass, and the rest are already resolved.
Bugs
None found. I checked the clip-semantics change in Canvas::place against its recording branch and its callers (layout.rs:252, layout.rs:1885); the clip is in the parent's space in both branches. The export colour-vision gate in render_frame is consistent with post::apply, which is forced to Normal for exports (lib.rs:4483). The MGRS zone-first check and the STAC asset selector are also correct. Confidence: high.
Security
None found. The new STAC notice bounds its list to five codes. Confidence: high.
Performance
The per-placement full-page mask in canvas.rs:247 is a known cost, already raised and answered as a release-pass item. Not re-posted.
Quality
The new zone check in parse_mgrs (utm.rs:589) duplicates the check in locate (utm.rs:480). It is harmless. Confidence: high.
The PR description is stale. It quotes the overflow notice as "its vectors would pass N MB", but the code says "kept as vectors, it would pass the drawing limit (N MB or M million items)". Confidence: high.
AGENTS.md
The new engine notices in stac.rs and share.rs are plain strings. The engine has no tl! or i18n::fmt calls, and connectionui::translated maps only some strings. So these two notices show in English, as the existing pictured_notices text does. This follows existing practice rather than being a PR-specific defect. Confidence: low.
I did not build or run the tests. CI results per the PR body are the basis for compile and test status.

Part of the release quality sweep: review points on the geometry, render, map and engine code left for the release quality pass.
parse_mgrsjudges the zone (1 to 60) before the band letter, asparse_utmdoes, so0AAAand61AVEreport the bad zone instead of an unsupported polar reference; two rows added toinvalid_mgrs_is_refused(review).POLE_TOLERANCE's doc no longer says only the tests use it: it names the engine's polar edits and analysis's topology, conversion and network code (review, comment, comment).Canvas::placeclips a pixel child toclipthrough a mask, as the recorded branch does, with a test that pixels outside the clip stay empty (review).render_framerecords vectors only when no colour-vision simulation applies, so vectors can't skip it (review).connectionparameter that isn't text gets "connection must be a saved web-service connection id (text)", and an unknown id in a web request reads asNO_SUCH_CONNECTION(comment).stac.addAssetwarns when the asset's metadata namesje:rastersdn.errorcodes for a failed retrieval (or names them in a way that can't be read whole), since a single file draws them as values; a regression test checks the coded asset gives the notice and a clean one none (comment).Left out: nothing.
