feat(plugins): a plugin command's layer.addUrl with "bbox" goes to the app (#1330, part 2) - #1581
Closes#1330. Part 1 (#1512) read a window in the app off the frame for ui.addUrl. A plugin's command run by the app still couldn't ask for one: it can't wait, so #1210 refused "bbox" there with a message. That left out BrasilData's MapBiomas windows, the case #1204 was opened for.
Now layer.addUrl {"bbox"} from a plugin's command goes to the same queue as any download (request_url). The app reads the window off the frame and adds it, and the command runs again with what adding it answered (#1202, #1341):
let added = host::call("layer.addUrl",json!({"url": url,"bbox": bbox,"name":"MapBiomas 2024"}))?;if added.get("pending").is_some(){returnOk(json!({}));// runs again once the layer is in}
Changes
rustgis-engine, cmd/layer.rs: the refusal goes. A box that can't be read is still refused as the command runs, so the plugin hears it at once, not after a queue.
rustgis-engine, policy/downloads.rs: a landed window completes its request's claim with "window" (what part 1's start_window_read says it read). Until now a claim took no key its request didn't have, so the window was refused with "the download's address or parameters changed since it was requested" and the command never ran again. The claim now takes "window" only when it repeats the request's own box, cell size and "cog", and nothing else (asked_window).
docs/plugins.md, docs/user-guide/data-formats.md: a plugin's window.
Choices and known limits
A window counts as a download: the 16 waiting, and REQUEST_WAIT's 10 minutes. A window waits up to about 7 minutes itself (five, and two more for the last band), and windows are read one at a time, so a command asking for several slow windows may run out of its wait. Those that land later aren't added, and that is said ("it came after its plugin command stopped waiting").
"view" is the view when the command asked: the queued request keeps that box beside its parameters (UrlRequest::view_asked), and the app reads it, even when a command run again after a download asks on a frame where the map shows another view. The command run again matches it by what it asked for ("view"), not by the box.
Scripts and models the desktop app runs take the same path: layer.addUrl with "bbox" is answered "pending" and the app reads and adds the window, as it does for a whole file they download (on main they got an error). Test: a_script_run_by_the_app_leaves_a_window_to_it.
Cancelling is left for a follow-up, as in part 1.
Tests
a_cog_window_comes_in_as_a_raster (engine): its refusal check is now the request: pending, with its box, nothing fetched, and a bad box refused.
a_landed_window_completes_only_what_was_asked (engine, policy::downloads): the same box and cell size are taken; another box, a cell size left out, a "cog" not asked, another key, a non-object and a request with no box are refused.
a_plugin_command_runs_again_when_its_window_is_added (engine): a plugin command asks for a window, which is read apart from the session, landed under the request's claim with its window, and added; the command run again answers the raster's id, with one layer added and nothing left waiting. It fails with the window refinement taken out of download_params.
a_plugin_reads_a_window_off_the_frame (UI): a real plugin command, a slow server, frames going on, the layer added once, the command run again with no error. It failed on the rebased branch before the claim change (the refusal above), and passes with it.
Run on Windows at 19659b5a (on main de346f17): cargo fmt --check and clippy -D warnings on both crates pass. rustgis-engine lib 974 passed (5 ignored), rustgis-ui-egui lib 731 passed. At 2715012e (one engine test added): rustgis-engine lib 975 passed (5 ignored), fmt and clippy pass.
Not run: the wasm32 build, Linux and macOS, a real window of the app, and a real BrasilData command on a MapBiomas file.
Desktop requests for a cloud-optimised GeoTIFF window using a bounding box can now continue through the asynchronous download flow. The requested layer is added when processing completes, and the plugin command resumes with the result without adding the layer twice.
The app remains responsive while the window is read, and invalid bounding boxes are rejected without fetching data.
Documentation
Updated plugin and data-format guides to describe the desktop window-request flow and how plugin commands resume after the layer is added.
…the app (opengeos#1330, part 2)
A plugin's command run by the app was refused a window, since it can't wait.
Now it is left to the app like any download: the read runs off the frame, the
layer lands, and the command runs again with what adding it answered (opengeos#1202).
A box that can't be read is still refused while the command runs.
The landed window completes its request's claim with "window" (what it
read), which the claim takes only when it repeats the request's own box, cell
size and "cog".

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.
Desktop plugin commands can submit validated COG window requests through the asynchronous download flow. The app adds the raster layer when the read completes, then reruns the plugin command with the result. A "bbox": "view" request uses the extent recorded when the command was made.
Changes: Desktop COG window requests
Layer / File(s)
Summary
Validate and queue window requests crates/engine/src/cmd/layer.rs, crates/engine/src/lib.rs
Desktop commands queue settled COG window requests when leave_downloads is enabled. For "bbox": "view", the queued request retains the extent recorded when the command was made.
Read and land queued windows crates/engine/src/policy/downloads.rs, crates/ui-egui/src/lib.rs
Download policy checks that the landed window matches the original request. The desktop read path passes the retained view extent to window validation.
Verify and describe plugin behavior crates/engine/src/tests.rs, crates/ui-egui/src/pluginpanel.rs, docs/plugins.md, docs/user-guide/data-formats.md
Tests cover pending requests, view capture, non-blocking frames, and command resumption without duplicate layers. The documentation describes the desktop window download and plugin retry flow.
opengeos/RustGIS#1341 — Adds the plugin request queue and rerun behavior used by this window-request path.
opengeos/RustGIS#1512 — Adds the COG window read and landing path extended by this change.

Explanation
The title names the main change: plugin command layer.addUrl requests with "bbox" now go to the app download queue instead of being refused. It also names the feature area (plugins) and the part reference (#1330, part 2). It is specific and matches the changeset, which removes the plugin-path refusal in cmd/layer.rs and adds window handling in policy/downloads.rs and the UI path. The only weakness is length (92 characters), which is slightly long but still readable.
Full details: Linked Issues check
Explanation
[#1330] Checked against the whole-PR diff (merge base 823e334, head c01bb07). The change since the previous review (dd95812) was read where possible.
Objective A: plugin path with leave_downloads. A plugin command's layer.addUrl with "bbox" goes to the download queue (request_url), not to a refusal. The previous review verified this in crates/engine/src/cmd/layer.rs at dd95812. The head summary states the refusal stays removed and an unreadable box is still refused while the command runs. The layer.rs diff at head could not be read because changed blobs are missing from the checkout. This objective therefore rests on the prior review and the head summary.
Objective B: a landed window completes its request only when it matches. crates/engine/src/policy/downloads.rs at head defines asked_window. It accepts a "window" refinement only when the request has a non-null bbox and the window keys are a subset of bbox, cellSize and cog, each equal to the request. Read directly at head.
Objective C: read/add split and app worker. crates/ui-egui/src/lib.rs at head passes UrlRequest::view_asked() to start_window_read, which calls window_asked_in. The incremental diff was read. The split exists at base, per the prior review.
Objective D: limits and cancellation. The head summary reports no change to the value, band or five-minute limits. Cancellation is deferred by the issue.
Objective E: "view" handling. The view is stored in UrlRequest::view at enqueue (read in downloads.rs at head). This matches the current PR description. The description mismatch noted in the prior review is resolved.
Tests: test names are present in the sources, per the head summary. Reported test runs cover 19659b5 and 2715012 only. No run is reported at c01bb07, so the head test pass state is unverified. This does not show an unmet coding requirement.
No unmet coding requirement of #1330 is shown. Open uncertainty: layer.rs at head was not read directly.
crates/engine/src/lib.rs: UrlRequest gains an optional view box and the accessor view_asked(). Session gains window_view. These hold the view that a plugin window request asked for, so a rerun matches it. In scope.
crates/engine/src/policy/downloads.rs (read at head): enqueue takes window_view into the queued UrlRequest. The checkpoint copy keeps the view. asked_window implements the "window" completion. In scope.
crates/ui-egui/src/lib.rs (diff read): ui.addUrl passes the request's view_asked() to start_window_read, which passes it to window_asked_in. In scope.
crates/engine/src/cmd/layer.rs: the window_asked_in entry point and the recorded-extent handling for "view" (per head summary). Layer.rs diff at head could not be read, so this rests on the summary.
Tests and docs (docs/plugins.md, docs/user-guide/data-formats.md): describe and test the plugin window path. In scope.
No change in the read hunks is unrelated to #1330. The public items window_asked_in and view_asked are used by the app crate, so they are needed. Open uncertainty: layer.rs and tests.rs at head were not read directly.
Full details: Docstring Coverage
Explanation
Docstring coverage is 83.33% 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 12 functions across 5 files. (1 skipped: 1 too large.)
Full details: Description check
Explanation
The description follows the repository template's sections (Summary, Testing, UI evidence, Related issue) and fills in the substantive content. The Summary explains what changed and why, linking to #1330 and the prior parts. The Testing section names specific tests, the platforms and commands run, and what was not run. The Related issue section cites Closes #1330. The UI evidence section is replaced by the 'No visible UI change.' line, which the template permits when there is no visible UI change. The 'Related issue' template comment is removed and replaced by content, which is fine. Minor point: the description does not state whether the UI change is visible; the UI test added is an egui test, not a screenshot, but the change does not alter rendering, so the 'No visible UI change' line is reasonable. Overall the description is mostly complete and specific.

A rabbit queued a window read, While map views shifted past the screen. The app brought back the raster layer, The plugin resumed its work again. One layer landed, neat and clean.
Bugs. No confirmed bugs. I traced the window path end to end: the claim's stored params, start_window_read's copy of bbox/cellSize/cog into the "window" marker, download_params's refinement, the rerun path, the 16-read cap, and the wasm gating. They agree. Confidence: high. I did not build or run the tests; the PR reports them passing on Windows only.
Security. Nothing new. The "window" refinement only checks that the marker matches the claim's own request. The landed raster comes from the engine-held landed_windows entry, not from the marker. Windows now go through the same request_url queue as whole downloads, so any plugin permission gate on that queue applies to them too. I did not trace that gate. Confidence: medium.
Performance. Nothing material. window_checks and window_settled run once at command time and again in window_asked on the frame, which is negligible. Confidence: high.
Quality.
crates/ui-egui/src/lib.rs:4576 and crates/engine/src/policy/downloads.rs:16 each hold their own copy of ["bbox", "cellSize", "cog"]. If one list changes without the other, every landed window is refused as "changed since it was requested". A shared constant would keep them in step. Confidence: medium. Nit, for the release quality pass.
crates/engine/src/cmd/layer.rs:3253 discards the value of window_settled(s, p, url)?. It reads like a value is being used, but it is only a validity check. Something like check_window would say what it does. Confidence: high. Nit.
AGENTS.md. No violations found. The new non-test code has no unwrap, expect, or indexing. The window_settled call is inside the native-only cfg block, which matches its definition. asked_window is platform-neutral. Docs were updated for the new behaviour. Confidence: high.
Earlier concerns left alone: 0. There were no prior review threads on this PR.

On the review summary's two quality nits (CodeRabbit's threads are answered inline; a test was added in 2715012e):
Two copies of ["bbox", "cellSize", "cog"] (ui-egui/src/lib.rs and policy/downloads.rs): left for the release quality pass, as the review suggests. A key added to the app's copy alone puts a key in the marker that asked_window doesn't know, so every landed window is refused, and the UI test a_plugin_reads_a_window_off_the_frame fails on it. A key added to the engine's copy alone changes nothing, as a key the request and the marker both lack compares equal.
window_settled(s, p, url)? used only as a check: a rename to say so is also left for that pass, to keep this PR to the plugin path.
The failing build (and Source distribution/claude-review on #1585) are GitHub 504s downloading trunk and Bun, not the code.

I read the diff, the staged metadata and prior threads, and the source it touches: the window request path in layer.rs, the claim matching in downloads.rs, the app's start_window_read and add_url in ui-egui/src/lib.rs, and the error redaction at layer.rs:3201. I did not build or run the tests, since this review had no shell.
Bugs
None confirmed. I traced the flow end to end. asked_window compares the stored request with the window metadata the app writes, and the two match for "view" because both carry the raw value. The leave path is gated on leave_downloads, which only plugin commands run by the app set. The wasm build keeps the old behaviour. (Confidence: ~75%. Nothing was executed.)
Security
None. The window refinement only accepts keys drawn from bbox/cellSize/cog whose values equal what was asked, so it cannot change the request. The new error paths pass through redact_text at layer.rs:3201, so URL keys don't leak. (Confidence: high.)
Performance
None. The one-read-at-a-time turn and the 16-read cap are as designed.
Quality
Duplicated key list (nit, confidence high).["bbox", "cellSize", "cog"] appears in policy/downloads.rs (asked_window) and in ui-egui/src/lib.rs:4637 (start_window_read). If one list changes and the other doesn't, a landed window is refused with "parameters changed". That is a loud refusal, not silent data loss. This is a quality point, so it can wait for the release quality pass.
AGENTS.md
No violations found. The added non-test code has no unwrap, expect, panic or unsafe. The new tests use unwrap, which is allowed in test code. Errors are reported as command errors, not silently dropped. The docs were updated for the desktop behaviour.
Prior review threads
I left 5 earlier concerns alone:
The "view" ordering thread at layer.rs:3272 (unresolved). The author's reply covers the same-pass case. CodeRabbit's follow-up, a retry that queues a new "view" window after an earlier one lands, has no answer. I did not verify it, so I am not re-raising it, but a maintainer should decide it.
The engine test thread and the UI retry-assertion thread (both resolved).
The desktop cellSize/cog test thread (answered, accepted).
The zoom thread (outdated, withdrawn).

@giswqs Would this fit in v0.6.0 before the tag? It's mergeable with CI green; the one open thread (view-box ordering in layer.rs) is left for a maintainer's call. BrasilData's MapBiomas clip by area waits on it.
Sorry, I didn't see this before making the release. My email is not working as intended with hundreds of GitHub notification emails everyday. This will be included in the release next week.
… in (opengeos#1330)
A plugin command run again after a download sees the view it first ran
with only while it runs; the app reads the window it then asks for on a
later frame, when the map shows the user's view again. The request now
carries the box "view" was when it was asked for, and the app reads that
box. A caller can't give it: the key is dropped from what a command asks.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
I read the full 339-line diff, the callers and helpers it touches (window_box, window_settled, download_params, enqueue_url_for, start_window_read), and the prior review threads. I could not compile or run tests here, so the findings below come from reading the code.
Bugs
Wasm build likely breaks under -D warnings (layer.rs:4435, high confidence, inline comment posted). is_view is ungated, but its only callers are native-only. ci.yml sets RUSTFLAGS: -D warnings for the wasm build, so dead_code should fail it. The suggested fix is to add #[cfg(not(target_arch = "wasm32"))].
Security
None found. viewAsked is stripped in add_url_as_given before the request is queued, and window_box still applies the lon/lat range and w < e / so < n checks to the saved box. A caller cannot widen the read with it.
Performance
None found. The added p.clone() runs once per layer.addUrl call with a window.
Quality (low confidence, for the release quality pass)
start_window_read (ui-egui/src/lib.rs:4617) takes the raw p for ui.addUrl, so a native ui.addUrl call that supplies viewAsked directly would read that box instead of the view. This needs a native user to make the call and gives no more than a plain bbox does, so impact is low. Stripping the key in start_window_read too would match the "not a caller's to give" comment.
The "window" completion check in asked_window is close to a self-check. start_window_read builds window from the same request's bbox/cellSize/cog, so the check guards against drift between claim and echo, not against a wrong read. The PR text describes it more strongly than that.
The comment at layer.rs:3278–3279 ("a command run again … sees the view it first ran with only while it runs") is hard to follow.
AGENTS.md
No new unwrap/expect/panic in non-test code. The new tests use unwrap, which is allowed there.
No new user-visible strings, so no tl! wrapping is needed. The new refusal and notice text is engine-side and not translated, as before.
Windows are still refused for "as" / "whole" / templates, and unread keys are refused rather than dropped.
The PR body includes a screenshot note, but the diff has no visible UI change that needs one.
Prior reviews
I left alone 6 earlier concerns already raised on this PR: the view-drift thread (answered; VIEW_ASKED is computed at ask time inside the command run, so the retry case is covered), the zoom refinement (answered, existing rule), the cellSize/cog test coverage (answered and accepted), and two test-assertion threads (resolved).

The box "bbox": "view" was when a command asked is kept on the queued
request (UrlRequest::view_asked) instead of in its parameters, so a
command run again is matched by what it asked and is answered the raster
added, and no caller can give the box. is_view is native-only, as its
callers are (the wasm build has -D warnings). The view test now completes
the window and checks the command run again gets the raster.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Low-to-moderate confidence: a "bbox": "view" request can be deduplicated into a queued request that holds an older view box. same_request compares parameters only, so the second command's rerun is answered with the first view's raster, and nothing says so. Posted inline on crates/engine/src/policy/downloads.rs:284.
I checked and found no other bug. The is_view wasm gating that the earlier thread raised is applied, and the wasm add_cog_window stub exists. The window completion marker matches what start_window_read writes, so a "view" request marker is {"bbox": "view"} and matches asked_window.
Security
None found. The view box is set only on the trusted queue path, so a direct ui.addUrl cannot inject a box. window is accepted at completion only when it repeats the request's own box, cell size and cog, and a window with no landed read is refused.
Performance
None found.
Quality (grouped nits, not posted inline)
crates/engine/src/cmd/layer.rs:4400: seen.unwrap_or_default() behind a guard that checks seen.is_some() silently yields a zero box if the guard and the body ever diverge. A match seen would be clearer.
The ["bbox", "cellSize", "cog"] key list is duplicated in start_window_read and in asked_window's KEYS. A key added to one but not the other is refused as "changed since requested", so it is loud rather than silent, but the two lists should share a constant.
The window_view field on Session passes an argument through shared state, set and reset around request_url. Passing it as a parameter would be safer.
The comment in add_url_as_given ("a command run again after a download sees the view it first ran with only while it runs") is hard to parse.
AGENTS.md
Compliant with the never-crash, never-silent, layering and wasm rules as far as I could read. The window refusal is replaced by a queued request, the test checks both paths, and the docs are updated.
Not verified: I could not run the build or tests here. The PR itself says the wasm32 build was not run.
Prior reviews: 10 earlier threads exist. I left all of them alone: none raises a new concern, and the is_view wasm point is already applied in the code. The view-timing and zoom points were answered by the author, and the rest were resolved.

- Around line 3275-3278: Update window-request matching around
`s.request_url(&asked)` to distinguish requests by the resolved view in
`settled.bbox`, so a command issued after the map moves cannot reuse a pending

…iew (opengeos#1330)
A request for the view joined a queued or in-flight one by its
parameters alone, so a command that moved the map between two such
requests got the first view's raster for the second. The queued match
compares the request's view box too, and the in-flight match the box kept
by request number (pruned with the requests). window_box matches on seen
instead of unwrapping behind a guard.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
I read the full diff, the prior review threads, and the surrounding engine and UI code. I checked the window-completion path (download_params / asked_window), the view-request queueing, the rerun path, and the wasm gating. The main behaviour holds up: the view box is kept beside the request rather than in its parameters, the is_view wasm gate is in place, and the cellSize / cog handling matches what start_window_read writes. I found no crash path and no silent data loss. The findings below are about state consistency and test coverage.
Bugs
crates/engine/src/policy/downloads.rs:266: the view filter runs after in_flight has already picked one match, so a matching landed window can be skipped and downloaded again, producing a duplicate layer. Low severity, confidence medium.
crates/engine/src/cmd/plugin_fetch.rs:951: window_views is not part of PutAside or the rollback snapshot, so the prune runs against state missing the aside or reverted waits and drops their view keys. It also sits after the early return in poll_plugin_retries_at, so entries persist while no command waits. Low severity, confidence medium.
Security
None found. Window completion still goes through asked_window, and the view box is not caller-supplied.
Performance
None significant. window_views is bounded by the number of plugin view requests, and pruning is linear in the queue size.
Quality
crates/engine/src/policy/downloads.rs:242: the queued and in-flight view-join rules have no test. The PR says plugin tests can't make two calls in one run, but engine tests can set window_view and call request_url directly, as existing tests do. Confidence high. The author acknowledged the gap, but the engine-level test is new evidence, so I raised it again.
AGENTS.md
Wasm gating, unwrap use, and Session::notify reporting are all consistent with the guidelines. No new user-visible strings were added in the diff, so no tl! wrapping was needed.
Prior reviews: I left alone 13 earlier concerns that threads already raise or that have been answered and resolved (wasm dead code, the view-spoofing trust boundary, rerun matching, zoom refinement, test coverage for bbox/cellSize/cog and the retry answer). I posted three new findings, and none repeats a prior thread.

… lookup (opengeos#1330)
The boxes of view windows, by request number, now live in UrlWaits, so
they go aside with a project, come back with it and are restored on a
rollback as the waits are; they are pruned with the waits and cleared
when no command waits. The in-flight lookup checks the view inside its
match, so it returns the first request that agrees on it. A test queues
view requests in two views and with none.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Low confidence (about 25%): poll_plugin_retries_at now clears url_waits.views on its early return (crates/engine/src/cmd/plugin_fetch.rs:889), but that path skips keep_only, so in_flight and landed entries can survive without their view keys. A later "view" request in the same view then fails the views.get(n) == window_view check and downloads the window again, which adds a duplicate layer. I could only reach this if plugin_retries empties without going through keep_only, so the window is narrow. A possible fix is to call self.url_waits.keep_only(&[]) on that path instead of clearing views alone.
No other confirmed bugs. I checked the join rules in enqueue_url_for, the in-flight lookup, the window refinement in download_params, and the window_view set/reset around request_url.
Security
None found. The "window" refinement only accepts a box, cell size and "cog" that match the request. window_view is set only from the app's queued request and is not caller-settable.
Performance
None found. views is pruned with the waits, and the in-flight lookup keeps its existing shape.
Quality
Low confidence: rerun_answer (plugin_fetch.rs:681) still matches on parameters only, with no view. This is safe only because poll_plugin_retries_at restores the held camera for the whole rerun (plugin_fetch.rs:930-942). A comment at rerun_answer saying so would protect that invariant.
Nit, for the release quality pass: window_settled (layer.rs:50) has a long signature, and asked_window (downloads.rs:222) is a dense one-liner.
AGENTS.md
Never crash: no new unwrap, expect or panic in non-test code. The new tests cover the refusal paths.
Never silent: a window that can't be read is refused while the command runs, and late landings are still reported.
Wasm: is_view is gated to non-wasm, which fixes the earlier dead-code failure. The new ungated items are all used on wasm.
Interface text: the diff adds no new user-visible literals.
Tests: refusal and clean paths are both covered, including the regression tests for the claim and the view join.
Docs: plugins.md and data-formats.md describe the new flow accurately.
I left 15 earlier review threads alone: 13 are resolved or answered, and 2 are withdrawn or outdated. I raised none of them again. The rerun_answer point above is the one I checked against the author's reply, and the same-run invariant answers it. I posted no inline comments, since nothing here reached the bar for one.
Change size
Compared: the whole PR against main (merge base 823e334 to PR head 159e418).
I read the full diff and the surrounding engine and UI code. The window path, the view-window matching (viewAsked, window_views/UrlWaits::views), the completion check (asked_window) and the wasm gating all hold up on reading. I found one quality issue worth fixing in this PR (posted inline) and two minor nits. I didn't compile or run the tests, so the wasm and test claims are from reading only.
Bugs
None found. I traced rerun_answer (matches by same_request, which includes viewAsked), the in-flight and queued view joins, the rollback path (views lives in UrlWaits), and prune_views/keep_only. They are consistent. The poll_plugin_retries_at camera restore keeps the rerun's viewAsked equal to the stored one. That relies on exact float equality of a restored camera, which holds because the camera and size are restored verbatim.
Security
None found. The window completion key only relaxes equality for the box, cell size and "cog" the request asked for. url and other keys still must match. Errors from add_url_as_given pass through add_url's redact_text.
Performance
None significant. prune_views runs every frame when no command waits, but its maps hold at most 16 entries.
Quality
crates/engine/src/cmd/plugin_fetch.rs:319 (high confidence): the UrlWaits doc comment now attaches to the new VIEW_ASKED const. Posted inline with a suggestion to reorder.
Nit, low confidence:without_request/asked_for don't strip a caller-supplied viewAsked key, unlike request. I traced it and it's harmless (per-caller matching, and with_view overwrites it when a view is set), but a reserved key is cleaner stripped.
Nit:docs/user-guide/data-formats.md line ~683 is over 100 columns and wraps unevenly with the lines around it.
AGENTS.md
No violations found. Gating matches the wasm rules, is_view and window_asked_in are cfg'd to match their callers, there are no non-test unwraps, and the script-path behaviour change is documented as intended. Rustfmt width (140) is respected.
Earlier concerns
I left alone all 17 review threads already on this PR, because none still points at code that is wrong. Ten were resolved by a fix, one was answered and accepted, and the rest were answered as intended or left as a known limit. The one I did not re-raise is the desktop-path test for cellSize/cog, which the author declined.
Change size
Compared: the whole PR against main (merge base 823e334 to PR head 76b3198).
Verdict: I found no confirmed bugs, security problems, or AGENTS.md violations. The window queue, dedupe, rerun matching, and completion checks hold together when traced through the code. The findings below are low-confidence or nits.
Bugs: none confirmed. I traced these paths and they are consistent:
The "window" completion object and asked_window both copy the raw request params, so a "view" box stays the string "view" on both sides and matches.
The retry restores both camera and view_size before rerunning (plugin_fetch.rs:949-952). The exact-float view box used by rerun_answer therefore matches the one captured at queue time.
in_flight's owns predicate guards landed windows as well as in-flight ones.
Confidence the paths are sound: high.
Low-confidence concern: add_url_as_given sets s.window_view and resets it after request_url (layer.rs:3284-3286). If a panic escapes request_url, the stale view tag could be attached to later non-window requests. Expected impact is small, since Session::run already catches panics. Confidence about 20%.
Low-confidence concern: the rerun path now runs window_settled(...)? before rerun_answer (layer.rs:3224-3226). A box error would therefore be reported before an already-landed answer. This only happens if the restored view differs, which the retry restore appears to prevent. Confidence about 15%.
Security: none found. Checked:
The GeoLibre import builds its layer.addUrl params from fixed keys, so it cannot inject a bbox.
STAC's add has no bbox.
A completed "window" is accepted only when it equals the asked box, so a claim cannot be redirected to a different box.
Scripts and models run in the app can now fetch windows. That is the same trust already given to their whole-file downloads. Confidence high.
Performance:prune_views (plugin_fetch.rs:618-622) allocates a Vec on every poll frame, even when views is empty. An is_empty() early return would skip it. Negligible. Confidence high.
Quality (nits, grouped; per AGENTS these can wait for the release quality pass):
layer.rs:3225: at recomputes url, which is already trimmed and non-empty from line 3216. Pass url instead. The Some(b) if … is_view(Some(b)) arm could also be is_view(p.get("bbox")).
tests.rs: the test name a_command_run_again_gets_each_view_s_own_window has a stray _s where an apostrophe was stripped.
docs/user-guide/data-formats.md:686 reflows awkwardly. The CLI sentence now says "in Python" and drops "script", though CLI scripts still wait.
pluginpanel.rs (a_plugin_reads_a_window_off_the_frame) uses 10 s and 30 s wall-clock deadlines plus a 5 s per-frame bound. It may be flaky on loaded Windows or macOS runners. Confidence about 30%; I have not run it.
AGENTS.md: no new unwrap, expect, panic, or unsafe in non-test code. The wasm gating is handled: is_view is gated, and the ungated window_view, views, and with_view are used only by ungated code. No new user-visible strings. The docs are updated. No visible UI change, so no screenshot is needed.
Earlier review threads: 18 threads on this PR were in prior-reviews.json. I left all of them alone. One point is still open: the in-flight half of the "join only the same view" rule has no test. The author's reply covered only the queued half, though the reviewer asked for both. That is a quality point, so I did not re-post it.
I posted no inline comments. None of the findings is strong enough for one, and the nits fall under the release quality pass.

No Cancel for window reads (AGENTS.md › Never hold the window, confidence: high that the rule isn't met; the PR text says it is deferred).
This PR widens who can start a window read: plugin commands, scripts and models now queue "bbox" windows, not only the UI. The read runs on a thread, but nothing can stop it:
read_cog_window (crates/engine/src/cmd/layer.rs:4141) never looks at control::check, Pace or progress::check, and no cancel is registered for start_window_read here.
All reads go through the process-wide WINDOW_TURN mutex (crates/ui-egui/src/lib.rs:193), so one slow server holds every other window read, in every project, for up to the roughly seven minutes the PR describes. A waiting read can give up only when its project closes (left), not when the user asks.
AGENTS.md says Cancel is "not optional" for these commands, and the PR's "Cancelling is left for a follow-up, as in part 1" doesn't meet that. Either add Cancel (a flag the read loop checks, with a button in the download status) before merge, or get a maintainer to accept the deferral explicitly.
The reason will be displayed to describe this comment to others. Learn more.
Right that the rule isn't met, and no download meets it yet: a plain ui.addUrl download (Downloading {url}…, then Downloading… {mb} MB in the status) has no Cancel either, and the window read off the frame came in with #1512 the same way. This PR moves windows asked by commands, scripts and models onto that same path; it adds no new kind of read.
Cancel belongs to downloads as a whole, so I'd rather do it once for both kinds than give windows a button plain downloads lack: a flag per download id (Session::download_started already numbers them), a Cancel beside each in the status, and the reads looking at it. For a window that is before each band and in the wait on its tiles (read_values_counted_blocking waits up to two minutes on fetch_bands' channel; it would wait in short steps and look at the flag), so a slow server's turn on WINDOW_TURN ends within a moment of Cancel. A read waiting for its turn already gives up its place when left is set, and Cancel would set the same flag.
That is a change of its own (the tiles crate's blocking read takes the flag, plus the status UI), so I'd open it as a follow-up PR right after this one rather than grow this one. If a maintainer would rather have it here before merge, say so and I'll add it to this PR.
The reason will be displayed to describe this comment to others. Learn more.
Leaving this open for the maintainer's decision. The point stands: AGENTS.md says Cancel is not optional, and this PR widens window reads to plugin commands, scripts and models, so a slow server can hold WINDOW_TURN for every window read with no way to stop it. The proposed follow-up (one Cancel per download id for plain downloads and windows) is the right shape; whether it lands here or right after is the maintainer's call.
The reason will be displayed to describe this comment to others. Learn more.
The Cancel is in #1726, as proposed above. Each download under way, plain or a window, gets a Cancel in the status bar, by its download id. A window's read stops within a moment of it: the waits on the header and the tiles look at the window's left flag every 100 ms, before each band too, so a slow server no longer holds WINDOW_TURN for the other reads. Windows asked by plugin commands, scripts and models go through the same path since this PR, so they get it as well. Its limits, such as a whole file's transfer running to its end with its bytes thrown away, are in that PR's text.
No new correctness bugs found. I traced the view-keyed queueing, in-flight joins, rerun matching, rollback snapshots, download_params refinement and the wasm gating. They are consistent. (confidence: medium-high)
Security
None found. The new window completion key is accepted only when it equals the claim's own box, cell size and cog. The viewAsked value is overwritten whenever a view window is matched. (confidence: high)
Performance
Window reads are serialised by the global WINDOW_TURN mutex, so one slow server delays every window read in every project for up to about seven minutes. Covered in the inline comment below. (confidence: high)
Quality (nits, left for the release quality pass)
add_url_as_given (layer.rs:3276): Some(b) if … is_view(Some(b)) can be if s.leave_downloads && is_view(p.get("bbox")).
window_settled runs twice for the same request in add_url_as_given (around lines 3279 and 3331).
Session::window_view is a side channel set around request_url and cleared afterwards. Passing the view as an argument into enqueue_url_for would be clearer.
docs/user-guide/data-formats.md around line 686 has an over-long line from the reflow.
VIEW_ASKED is documented as "never read as a parameter", but a caller can still supply viewAsked for a non-view request, which passes through asked_for. It is harmless today because nothing reads it except the rerun match, which the caller can't use to get another answer. Stripping the key in asked_for would make the doc true.
AGENTS.md
Never hold the window: window reads have no Cancel. Posted inline at crates/ui-egui/src/lib.rs:4638.
The "never silent" and "never crash" rules look satisfied: refusals are said, the new paths use window_asked_in and window_checks, and non-test code has no unwrap/expect.
Already raised, left alone: 18 earlier review threads on this PR, all resolved. I did not re-raise any of them. The one about scripts now getting {"pending": true} instead of an error is answered and pinned by a test.

Low confidence (about 40%): a recorded step for a plugin's "view" window replays the view at replay time.
The box kept here is only used for the read and the rerun match. When the window lands, the completion goes through layer.addDownload with window: {"bbox": "view"}, and the step recorder (crates/ui-egui/src/lib.rs:2507) turns that into layer.addUrl with "bbox": "view". A replay then reads whatever view is current at that moment, not the box the command asked for. The same thing already happens for a ui.addUrl window from #1512. This PR extends it to plugin commands, scripts and models, so it may be worth a note in the recording path or the docs. I haven't checked whether plugin-run steps are recorded at all, so treat this as a question rather than a defect.
The reason will be displayed to describe this comment to others. Learn more.
Checked: plugin-run deliveries are recorded, as the host command and not as the plugin's (the recording check in permission_policy_plugin_deferred_probe_refuses_before_fallback, pluginpanel.rs: a plugin's layer.addUrl lands as one layer.addUrl step, without id or request). So a plugin's "view" window is recorded as layer.addUrl with "bbox": "view", and a replay reads the view current then.
That is by design and the same as every other step that reads the view: a recording doesn't keep the view ("Panes, dialogs and moving the view aren't recorded", Workspace › Record Task), so a step that asked for the view reads the one the replay is on, as a WCS coverage or a ui.addUrl window from #1512 does. A command that asked for a box ([w, s, e, n]) is recorded with that box and replays it. Keeping the resolved box instead would change what a "view" step means for one command only, so I've left it as is.
I found no high-confidence bugs, security problems or crash paths. I read the diff, the surrounding engine code (policy/downloads.rs, cmd/plugin_fetch.rs, cmd/layer.rs, the UI start_window_read path) and the 19 existing review threads. I posted one low-confidence inline comment (crates/engine/src/cmd/layer.rs:3337).
Bugs
Low confidence (~40%): a recorded step for a plugin's "view" window may replay the view at replay time, not the box the command asked for. The step recorder (crates/ui-egui/src/lib.rs:2507) turns the completion into layer.addUrl with "bbox": "view". This matches existing behaviour for ui.addUrl windows, so it is pre-existing semantics that this PR extends. Posted inline.
Security
None found. The window completion key is accepted only for an app-landed window whose box, cell size and cog match the claim exactly. viewAsked is only ever matched, never used to pick the box. A caller-supplied viewAsked is overwritten on the view path and otherwise just fails to match.
Performance
Nothing worth raising. The view map is bounded by in-flight and landed requests, and the duplicate window_settled call is cheap.
Quality (for the release quality pass, not posted inline)
Session::window_view is ambient state: set and cleared around request_url and read inside enqueue_url_for. Passing the view as a parameter would be clearer.
The view box lives in two places, UrlRequest.view and UrlWaits::views. prune_views is only safe because download_started_for re-inserts the box. That invariant should be written down in a comment.
docs/user-guide/data-formats.md:193 drops "in a script" from the command-line sentence, so it no longer says whether a script run from the command line waits.
In the view branch, window_settled runs before window_checks, so a bad view is reported before a bad bbox or cellSize. Minor.
AGENTS.md
Cancel for window reads: the rule is still not met. The open thread on crates/ui-egui/src/lib.rs:4638 already says so, and I did not repost it. The function signature changed, but the new code adds no new point to the existing concern.
Screenshots: the PR changes what the desktop app does for plugin commands and scripts, but its body includes no screenshots and says the real app was not run. AGENTS asks for screenshots of visible changes. Low to medium confidence.
Prior reviews: 19 threads were already on this PR. I left all 19 alone: 18 are resolved, and 1 (the Cancel thread) is still open for the maintainer.

Thanks @elpidioassinaturas. I reviewed this with the plugin security boundary in mind and found no problem there: the window request goes through request_url, so it is queued under the plugin command's own continuation (same scope and same_url_caller/check_continuation checks as a whole-file download), the URL is still checked by window_checks/web_address before queueing and again on the frame in window_asked_in, and the new "window" claim refinement only accepts exactly the box, cell size and "cog" the request asked for, so a completion cannot widen what was asked. The viewAsked match key is only compared within the same command's own landed requests.
What I did on the branch:
Merged main (clean, no conflicts).
Rewrapped the over-long line in docs/user-guide/data-formats.md (86b9113).
Engine lib tests pass locally on the merged head (1174 passed), and CI is green.
Open for the maintainer: the thread on Cancel for window reads. AGENTS.md says Cancel is not optional, and this PR widens window reads to plugin commands, scripts and models, so whether the per-download Cancel follow-up you describe must land in this PR or right after is a maintainer decision. I left that thread open.
A window's refusal names its address with opengeos#1501's message_with_address, and
keeps the view box it was asked with (window_settled's seen).

Bugs. No new bugs found. I checked the view keying across queue, in-flight dedupe, rerun matching, the claim refinement (asked_window), and the rollback path (UrlWaits::views). They agree. The open concern is the existing Cancel thread below, not a new bug.
Security. None found. The window box is read only from the queued request, never from caller params, so a caller-written viewAsked can't change what is read.
Performance. None found.
Quality
Stale doc comment on start_window_read: it still says scripts wait for a window in layer.addUrl, which this PR changes for scripts run in the app. Posted inline with a suggestion. High confidence.
viewAsked is not a reserved key. asked_for keeps every caller key, so a caller can still write viewAsked. This contradicts the reply on the earlier thread that there is "no viewAsked parameter any more". Harmless today, since it only affects request matching. Low confidence on impact, medium on the fact. I could not post this inline because asked_for is outside the PR's diff hunks. Suggested fix: remove VIEW_ASKED from the params in asked_for (crates/engine/src/cmd/plugin_fetch.rs, near line 684).
AGENTS.md
Window reads still have no Cancel, which AGENTS.md requires for long background work. Already raised on the open thread at crates/ui-egui/src/lib.rs:4666. Not re-raised here. High confidence the rule isn't met.
Otherwise no violations found: no unwrap/expect in non-test code, cfg gating for wasm checks out, and the new tests cover both the clean and the refused cases.
Prior reviews. 20 threads already on the PR. One is open (the Cancel thread, left alone). The rest are resolved, answered, or outdated, and I raised none of them again. The viewAsked point above is a re-raise of an answered thread, made because the reply's claim doesn't match the code.

Only the session tells windows of the view apart (with_view): asked_for drops a
caller-written viewAsked, so it is no parameter at all. start_window_read's doc
says who waits in layer.addUrl (the command line) and who leaves the window to
the app (a plugin's command or a script the app runs).

On the viewAsked point in the last review: you're right. asked_for kept a caller's own viewAsked, so my earlier reply ("no viewAsked parameter any more") was wrong. Fixed in c06e1d0: asked_for now drops VIEW_ASKED, so only Session::with_view adds it. A test checks that a request with a caller-written viewAsked is asked for exactly as one without it. Nothing read changes: the box still comes only from the queued request.
I read the full diff, the staged metadata and the 21 prior review threads, and checked the changed code against its callers in enqueue_url_for, poll_plugin_retries_at, download_params, start_window_read and the wasm cfg gating. I did not find a correctness bug in the changed lines. The notes below are test gaps and quality points.
Bugs: none confirmed. Checked and found sound: the viewAsked key is stripped on every entry path (asked_for, which enqueue_url_for also goes through); window_view reaches enqueue_url_for on both the authorized and the plain path; the views map is pruned consistently with in_flight and landed; the new helpers are either cfg-gated or used unconditionally, so the wasm build should not hit a new dead_code error.
Security: none found. The "window" completion key is only accepted when it matches the request's own box, cell size and "cog". A caller cannot inject viewAsked.
Performance: nothing material. prune_views is O(n²) over at most about 16 entries.
Quality (may wait for the release quality pass, per AGENTS.md):
Session::window_view is a mutable side channel. It is set around request_url in layer.rs, taken inside enqueue_url_for and reset by the caller. Passing the view as an argument would make the contract explicit. Confidence: medium.
add_url_as_given computes window_settled(...) twice on the view path (layer.rs:3368 and :3427). The two can drift. Confidence: high.
a_plugin_reads_a_window_off_the_frame asserts frame.elapsed() < 5s around a single h.step() (pluginpanel.rs:1019). This could be flaky on slow CI runners. Confidence: low.
AGENTS.md: the Never-hold-the-window Cancel point is still open (lib.rs:4667, thread from the github-actions review). I did not repeat it. The new code path and the read_cog_window loop are unchanged, so the earlier concern still stands.
Inline comments posted:
crates/engine/src/tests.rs:33192: the two-view rerun test builds rerun_landed itself, so a regression in the production mapping at plugin_fetch.rs:951 would not be caught. Confidence: medium.
crates/engine/src/tests.rs:33209: the in-flight half of the join rule has no test. The earlier thread was answered with a test that covers only the queued join. Confidence: medium.
Prior concerns: I left 21 earlier threads alone. Two are still open and were not repeated: the Cancel concern and the rerun-replay question on layer.rs:3433. The second was answered by the author and I have no new evidence against that answer.

…ew (opengeos#1330)
The in-flight half of the join rule had no test: a command asking again while the
window is read joins it in the same view, and asks again in another view or with
a box.

I found no bugs or security problems in the changed lines. I traced the queue and join rules, the rerun match, the retry camera restore, the app's window read and the claim refinement, and they agree with each other. asked_for strips viewAsked before anything is queued, so a plugin cannot choose the view box. I could not run the tests here; this is from reading the code.
Bugs
None found.
Security
None found. asked_window only lets a completion restate the asked box, cell size and cog. Any other key is refused.
Performance
None significant. prune_views runs each frame while no command waits, but it only scans a short list of live request numbers.
Quality
Low (about 25%):add_url_as_given (crates/engine/src/cmd/layer.rs:3366-3369) calls window_settled for every "view" call under leave_downloads, before rerun_answer is consulted, and then calls it again at line 3427. I can't find a reachable case where this refuses a rerun that should be answered, because a rerun restores the camera to the view that was valid when asked. Tidying it is optional. No inline comment.
Low: There is no test that a view window's box survives prune_views while it is in flight with no command waiting. This is a test gap, not a defect. Left for the release quality pass.
AGENTS.md
Never hold the window (high confidence, unchanged from an open thread): window reads still have no Cancel. start_window_read (crates/ui-egui/src/lib.rs:4667) only sets left when the project closes, and all reads share the global WINDOW_TURN lock. I did not repeat the open thread.
No unwrap, expect or panic in non-test code in the diff. The new wasm gating (is_view, window_settled, WindowAsked::bbox) is consistent with its callers, and the docs match the behaviour.
Earlier threads: I checked 23 review threads. I did not re-raise any of them. The Cancel concern is still open and still applies. The others are resolved, outdated or answered, and I found nothing in the current code that contradicts those answers. I posted no inline comments, because none of my findings is above the quality-pass level.

A resposta leva "report", que a janela do comando mostra depois de executar, em
vez do JSON. O GPX e o KML nomeiam cada ponto pelo campo name, e saíam com o
número da feição: o plugin cria esse campo com o rótulo (P01…) só durante a
gravação. A ajuda dos três comandos diz que os valores vêm da janela, e do painel
num RustGIS sem janelas de plugin.

Summary
Closes #1330. Part 1 (#1512) read a window in the app off the frame for
ui.addUrl. A plugin's command run by the app still couldn't ask for one: it can't wait, so #1210 refused"bbox"there with a message. That left out BrasilData's MapBiomas windows, the case #1204 was opened for.Now
layer.addUrl {"bbox"}from a plugin's command goes to the same queue as any download (request_url). The app reads the window off the frame and adds it, and the command runs again with what adding it answered (#1202, #1341):Changes
rustgis-engine,cmd/layer.rs: the refusal goes. A box that can't be read is still refused as the command runs, so the plugin hears it at once, not after a queue.rustgis-engine,policy/downloads.rs: a landed window completes its request's claim with"window"(what part 1'sstart_window_readsays it read). Until now a claim took no key its request didn't have, so the window was refused with "the download's address or parameters changed since it was requested" and the command never ran again. The claim now takes"window"only when it repeats the request's own box, cell size and"cog", and nothing else (asked_window).docs/plugins.md,docs/user-guide/data-formats.md: a plugin's window.Choices and known limits
REQUEST_WAIT's 10 minutes. A window waits up to about 7 minutes itself (five, and two more for the last band), and windows are read one at a time, so a command asking for several slow windows may run out of its wait. Those that land later aren't added, and that is said ("it came after its plugin command stopped waiting")."view"is the view when the command asked: the queued request keeps that box beside its parameters (UrlRequest::view_asked), and the app reads it, even when a command run again after a download asks on a frame where the map shows another view. The command run again matches it by what it asked for ("view"), not by the box.layer.addUrlwith"bbox"is answered"pending"and the app reads and adds the window, as it does for a whole file they download (onmainthey got an error). Test:a_script_run_by_the_app_leaves_a_window_to_it.Tests
a_cog_window_comes_in_as_a_raster(engine): its refusal check is now the request: pending, with its box, nothing fetched, and a bad box refused.a_landed_window_completes_only_what_was_asked(engine,policy::downloads): the same box and cell size are taken; another box, a cell size left out, a"cog"not asked, another key, a non-object and a request with no box are refused.a_plugin_command_runs_again_when_its_window_is_added(engine): a plugin command asks for a window, which is read apart from the session, landed under the request's claim with itswindow, and added; the command run again answers the raster's id, with one layer added and nothing left waiting. It fails with thewindowrefinement taken out ofdownload_params.a_plugin_reads_a_window_off_the_frame(UI): a real plugin command, a slow server, frames going on, the layer added once, the command run again with no error. It failed on the rebased branch before the claim change (the refusal above), and passes with it.Run on Windows at
