Part 2 of #1532: the Data Cubes pane now reads JAXA Earth's own catalog live, instead of the nine hand-picked entries I had planned for cubes.json. Part 1, the code that reads static STAC collections laid out by date, merged in #1557; this PR builds on it.

What it does

• Live catalog (crates/tiles/src/jaxa.rs). The pane reads https://data.earth.jaxa.jp/app/mcp/catalog.v2.md once a run, in the background, the first time it opens. Each EPSG:4326 dataset becomes one cube per band, with id <dataset id>/<band>. Title, provider, bbox, period, step and resolution come from the catalog. Themes come from the title, keywords and bands, and the keywords and bands are searchable. On today's catalog: 119 datasets, 78 of them become cubes, 80 cubes in all (AW3D30 has two bands, DSM and MSK).
• Nothing dropped silently. The pane counts the datasets left out and lists each one with its reason on hover. cube.catalog returns the same list under "jaxa". Left out today:
  • the 2 polar datasets (EPSG:3031/3995);
  • 31 climatologies (normal: true), whose MM dates have no year, so dated.rs refuses them;
  • 8 hourly series, which dated.rs also refuses.
• Collection addresses come from the catalog's collection field, accepted only in JAXA's two buckets (je-pds and je-pds2 on Wasabi) and only under the dataset's own id. 16 datasets live in je-pds2, so building the address from the id alone would 404 for them.
• Automatic range ("range": "auto" in stac.addCube, the default for any catalog entry without a range). It follows GeoLibre's percentileRange: the 2nd–98th percentiles of a sample, rounded outward to a step two orders of magnitude below the span.
  • The sample is the newest file of up to 4 of the cube's tiles, each read at its finest overview no larger than 512 px a side.
  • Values are scaled as the metadata says, and the codes for no value (dn.error) are left out.
  • One range covers every date and tile, and the answer returns it ("range", "rangeFrom": "sample").
  • In three cases each file is stretched on its own instead, as before: an empty sample, files whose scale changes partway, or palette files (which draw in their own colours). Each gets a notice.
  • The cell size for Trend Analysis is spatialResolution / 111.32 km, in degrees.
• Licence and credit.
  • Each collection's licence is its rel: license link (an SPDX license is the fallback). Most link JAXA's terms; some are NASA's or Copernicus's.
  • The pane reads the licence when an entry scrolls into view and shows it as a Licence link; if it can't be read, the link goes to JAXA's terms and the tooltip says why.
  • cube.open reads the licence too and returns it. A read that failed quickly (such as a 404) is tried again by the next cube.open; one that failed after 5 s or more, only 10 minutes later, its error given at once until then. The pane's link stays on JAXA's terms until a read succeeds.
  • The cube's tile layers carry the credit "JAXA, ", as JAXA's terms ask: cube.open passes it to stac.addCube as its new "attribution", which sets it on each tile layer the cube adds, also when the same cube is opened again.
• The hosted list keeps its behaviour. The rustgis-assets list still replaces the built-in one, and the JAXA entries are appended to whichever is in use. Their ids can't clash with the list's, which are lower-case and hyphenated; an entry that did would be left out.

Choices

• I studied GeoLibre's JAXA plugin (jaxa-earth-api.ts, maplibre-jaxa-earth.ts; opengeos/GeoLibre, MIT) but did not port it. The one method taken from it is percentileRange (2nd–98th percentiles, rounded outward), which cubes::percentile_range follows; the Rust code is written anew, not translated. RustGIS keeps its own reader (part 1) and its cube catalog, so a JAXA dataset opens, undoes, goes to Trend Analysis and reduces like any other cube.
• The range is sampled from the tiles that cover the area being opened, not the dataset's whole extent as in GeoLibre. A JAXA grid tile is large, so the sample still reaches well past the view.
• The licence is read lazily, per entry, rather than by fetching all 78 collections up front.
• cube.catalog doesn't start the network read itself, since it is a command without the network effect. A script that never opens the pane sees "jaxa": {"state": "unread"}.

Limits

• The catalog is read once a run. A failed read is retried only by Try again in the pane, and there is no cache on disk, so offline the JAXA entries are simply absent and the pane says why.
• Polar, climatology and hourly datasets are not cubes yet.
• The sampled range comes from the newest date only.
• Catalog text too long for the list (a title over 160 characters, a field over 2,000) is cut. Its name ends in "…", and the pane and cube.catalog ("jaxa"."cut") list each cut. They also name the fields that aren't read: a spatialResolution that isn't kilometres, a field given twice, a field name that isn't letters and digits. Today's catalog has none of these (a test checks it).

Tests

• jaxa.rs: parsing a full copy of today's catalog (fixture crates/tiles/tests/data/jaxa_catalog.v2.md; JAXA's terms allow redistribution with credit), what is left out and why (a dataset listed again too), refused addresses, licence links, the cut and not-read notes (past 500, one more says there are more), and the wait after a slow licence failure.
• cubes.rs: the percentile range and the combined list.
• Engine: an entry without a range opens with a sampled range, its credit and its licence, served by a local server. Opened again over the same files, it keeps its credit. A licence that can't be read gives a notice, and the next cube.open reads it. One whose server stalls isn't waited for again at the next cube.open. A palette COG takes no range and says so.
• Pane: the JAXA entries listed with credit, and the left-out line.
• No test touches the network.

Run locally on Windows:

• cargo fmt and cargo clippy --workspace --all-targets -D warnings: clean.
• cargo test -p rustgis-tiles: 347 passed.
• cargo test -p rustgis-ui-egui: all passed (738 in the lib).
• cargo test -p rustgis-engine: 1087 passed in the lib (the cube, catalog and STAC tests again after the last commit: 57 passed). The one failure, gdal_formats_open_when_gdal_is_installed, is unrelated: this PC has GDAL 3.7, and it fails on main here too.
• The wasm build can't run on this PC (zstd-sys needs clang); CI's "Web app (wasm32)" check covers it. Desktop-only code is behind cfg(not(target_arch = "wasm32")).

I also opened a real cube end to end with ui_shot: GSMaP monthly over South America, January–March 2024. It came up with one sampled range across both tiles and all three dates, and the map attribution read "JAXA, Precipitation Rate (Monthly)".

i18n/*.tsv is untouched, so the new strings are English only for now.

Screenshots of the pane with the live catalog are attached below.

Opening a cube can leave the interface unresponsive for minutes on slow reads. The catalog can also appear stuck loading until the user interacts again. Resolve these behaviors before merging unless their impact is explicitly accepted.

[github-actions]

Test order dependence. jaxa::take writes a process-wide static, and it is never reset. Once this test (or jaxa_earths_datasets_join_the_list) runs in the ui-egui test binary, every later test in that binary sees JAXA cubes in cubes::list(). The count-based assertions here compare against list() so they survive, but any test that expects the built-in list alone, or an exact total, will pass or fail depending on test order. Either reset the status at the end of each test that sets it, or put the status behind a test-only injection point and serialize those tests.

Confidence: medium. I did not run the tests, so this is from reading the code.

[elpidioassinaturas]

Left as is, after checking the ui-egui tests. The only ones that list catalog entries are the two in cubesui.rs. Both call jaxa_read() first and compare against cubes::list(), so they see the same list in any order. Every call sets the same fixture, so a test running alongside one doesn't see the list change. The other cube tests look entries up by id. The engine's exact-count assertion (cubes::built_in().len()) runs in a binary that never sets the catalog. A reset at the end of a test would itself race with tests running in parallel, so I'd add a test-only injection point only if a test comes to need the built-in list alone.

Code review

No earlier review threads existed, so every finding below is new. I read the full diff, the base-branch AGENTS.md, and the surrounding code (undo snapshots, download timeouts, COG level ordering, lint deny-list). I did not build or run the tests.

Bugs

• Palette sample gives no notice, contradicting the docs. stac.rs:1000 turns a palette sample into "no range" silently. web-data.md says a notice is given, and the PR body says it isn't. Inline comment posted. Confidence: high on the mismatch.

Security

• No findings. Catalog-derived collection URLs are limited to JAXA's two buckets and an id pattern, and licence links are limited to http(s).

Performance

• Unneeded map snapshot on every STAC add. cube_catalog.rs:100 clones every tile layer's dated file list even when the entry has no credit. Inline suggestion posted. Confidence: medium.

Quality

• Doc comment on the wrong test. tests.rs:16880: the new test was inserted between an existing doc block and a_catalog_entry_opens_as_its_command_would, which lost its doc. Inline comment posted.
• Test order dependence. cubesui.rs:322: jaxa::take writes process-wide state that is never reset. Inline comment posted. Confidence: medium; not run.
• Silent truncation of searchable text. jaxa.rs:290 cuts keywords to 600 characters with no notice (titles, providers and licence titles are cut the same way). Inline comment posted. Confidence: medium.
• Silent id collision. cubes.rs:175 drops a JAXA entry whose id matches a hosted one, with no notice. Unlikely, since hosted ids are lower-case and hyphenated. Confidence: low.
• Duplicate datasets vanish from the counts. jaxa.rs skips a listed-twice dataset without counting it as left out, but datasets still includes it, so the pane's "N of its M datasets" doesn't add up. Confidence: low.
• Nits (for the release quality pass): cubesui.rs:115 shadows the outer shown list with a bool; jaxa::licence_blocking (jaxa.rs:431) skips the is_collection check that fetch_licence applies; the new auto-range notices (empty sample, scale mismatch, read error) have no tests for the notice path.

AGENTS.md

• Fixture has no ATTRIBUTION.md row. crates/tiles/tests/data/jaxa_catalog.v2.md is a 96 KB copy of JAXA's third-party catalog, and the PR doesn't touch ATTRIBUTION.md. AGENTS requires a row for every asset file. Confidence: medium; the PR says JAXA's terms permit redistribution with credit, but that doesn't replace the row.
• Docs contradict the retry behaviour. web-data.md:220 says the catalog is read "only in a new run", but the pane's Try again reads it again on demand. Inline comment posted.
• Provenance note. The PR body names GeoLibre as the source it follows for the percentile range, which satisfies the naming rule. I could not check GeoLibre's licence offline, so confirm it is compatible. Confidence: low.
• Checked and fine: undo snapshots the whole project at the outermost command, so the credit change is captured. Downloads have timeouts. Overview levels are finest-first, matching the "finest overview" doc. No unwrap/expect in non-test code.

Already raised earlier: none. Concerns left alone: 0.

Code review

I read the diff, the staged metadata, and the surrounding source. I did not build or run the tests. The PR has 6 earlier review threads. I left 2 alone because they are still open and the code they point at is unchanged: the unconditional tile_files(s) clone in cube_catalog.rs, and the test-order dependence on the process-wide JAXA status in cubesui.rs. The other 4 are fixed in this push: the palette-class fallback now gives a notice, the doc comment is back on its test, words are no longer truncated, and the docs describe the retry.

Bugs

• No new correctness bugs found. I checked snapshot undo/redo (the credit mutation is inside cube.open, so redo keeps it), the Entry literals, the cfg(wasm) gating of sample_range, the levels ordering, and the percentile_range edge cases.

Security

• No injection or traversal path found. Collection URLs are limited to JAXA's two buckets with a validated id, and licence links are limited to http/https. licence_blocking does not repeat the is_collection check that fetch_licence makes. The URLs are validated at parse time, so this is defence in depth only. Confidence: low.

Performance

• Nothing new beyond the open thread on tile_files.

Quality

• Silent clips remain on the licence title (jaxa.rs:403) and on temporalResolution (jaxa.rs:334). Confidence: medium.
• licence_blocking (jaxa.rs:455) caches a transient failure for the whole run, with no retry, unlike the catalog. It also starts a second download when fetch_licence is already in flight. Confidence: medium.

AGENTS.md

• Never silent, high confidence: combined() (cubes.rs:175) drops a JAXA entry whose id matches a built-in one, with no notice. Commented.
• Never silent and get-over-index, high confidence: in stac.rs, else { continue } drops a sampled file with no notice, and l.levels[level] indexes where AGENTS asks for get(). Commented.
• Assets, medium-low confidence: the 98 KB JAXA catalog fixture has no ATTRIBUTION.md row. Commented.
• Docs, medium confidence: "JAXA asks to be told before commercial use" is not in the catalog copy, which says commercial use is free under the terms. Commented.

Five inline comments are posted: cubes.rs:175, stac.rs:1199, jaxa.rs:403, the fixture at line 1, and web-data.md:217.

Quality point, left for the release quality pass. This let shown shadows the list shown that the loop iterates over, which makes the loop hard to read. Naming it visible would avoid the shadowing, and licence_link could then take the flag without the #[cfg(test)] let _ = shown; workaround.

[elpidioassinaturas]

Left for the quality pass, as you suggest. Renaming the inner shown to visible would be clearer. I've kept this round to the confirmed bugs so the diff stays small.

🤖 Addressed by Claude Code

[github-actions]

The new notices have no tests (AGENTS: test both ways). The engine test covers only the palette case (Sample::Classes). Nothing exercises the Sample::Empty notice, the Err(e) "couldn't be sampled for a range" notice, or the licence-unreadable warning in cube_catalog::credit. Each is a notice a user relies on, so each needs a case where it fires and one where it doesn't.

Confidence: medium. This is a test gap, not a bug in the code shown.

[elpidioassinaturas]

Partly done in 109d2d8. The licence-unreadable warning now has a case where it fires: a collection that answers 404, with the cube still added and credited. In the first opening the licence is read, so license comes back and that branch doesn't warn. The palette notice fires for a palette COG, and the cases that sample a range don't give it.

Sample::Empty and the sample's Err aren't exercised yet. I tried a missing file for Err, but the cube's own read of that file fails first ("http status: 404"), so the cube isn't added at all. This notice only fires when the header reads and the overview the sample reads doesn't. Empty needs a file whose sampled overview is all no-data. The example COG generator (rustgis_data::raster::cog::example_with) makes neither, so a test needs a new fixture option in rustgis-data. I'd add it in a follow-up if a maintainer wants it in this PR's scope.

Code review

Bugs

• Nothing high-confidence found. The sampling, percentile and range code is correct on the cases I traced. Two low-confidence points:
  • licence_blocking caches a failed licence read for the whole run, so a transient network error on cube.open is never retried in that run. The catalog has a Try again button; licences have none. (low)
  • The pane and cube.catalog report "80 cubes from its catalog", but cubes::list() leaves out clashing-id entries, so the listed count can be lower. The hidden-cubes line does say so. (low)

Security

• No issues found. Collection addresses are limited to JAXA's two buckets and a validated id. Licence links must be http(s). The SPDX fallback id is charset-checked. Catalog text is size-bounded.

Performance

• cube.open runs synchronously on the UI thread (cubesui.rs:270). The PR adds blocking network reads there: up to four cog::info_blocking plus window reads for the sample (stac.rs:1191, 1202), and one licence_blocking (cube_catalog.rs:142). The count is bounded, and add_cube already does blocking reads, so this is latency rather than a growing hang. Still, it has no Cancel, and AGENTS asks for background work and Cancel where work grows with input. (low-medium)
• The earlier tile_files clone concern is unchanged in the code and the author has answered it. I left it alone.

Quality

• Inline: cubesui.rs:115 shadows shown. Left for the release quality pass.
• The if !hidden... block, the duplicate-dataset continue (jaxa.rs:193) and duplicate or invalid field keys (jaxa.rs:179) drop input without a notice. Low confidence each; the duplicate skip is the most likely to matter, since a second listing with different bands would be dropped silently.

AGENTS.md

• Never silent, inline: cut_note stops recording at 500 cuts with no notice (jaxa.rs:388). Medium-high.
• Never silent, inline: left-out titles are clipped to 200 characters with no notice (jaxa.rs:198). Medium.
• Test both ways, inline: the Sample::Empty, Err and licence-unreadable notices have no tests (stac.rs:1004). Medium.
• Asset rule: the fixture now has its ATTRIBUTION row, so the earlier concern is resolved.
• Provenance, low confidence: the PR says it studied GeoLibre's JAXA plugin but did not port it. The code comments say percentile_range "follows GeoLibre's percentileRange". If that function was followed rather than implemented from the published method, AGENTS requires naming it in the PR and checking the licence. I could not check GeoLibre's licence here.

Prior threads: 11 threads on this PR. 9 are resolved and I confirmed the fixes in the code. 2 are answered but still open (the tile_files clone and the ui-egui test order). I left those 2 alone because the code they point at has not changed. I posted 4 new inline comments.

Blocking network read on the command's thread, with no progress or Cancel. licence_blocking can wait up to 60 s (BLOCKING_TIMEOUT) for collection.json. It runs on every cube.open of a JAXA cube until a licence has read OK, and cube.open is a network command with no background path. sample_range in stac.rs adds up to four more blocking COG reads on the same path. The cube.open doc comment does not say why this stays on the UI thread (AGENTS: "A command that must run on the UI thread says why in its doc comment").

Options: take the licence from the background cache that the pane fills (jaxa::fetch_licence) and only say "not read yet" when it is missing; or add a doc comment that explains the choice and bounds the wait.

Confidence: medium. The reads are bounded, so this is about the rule and the worst-case stall, not a common-case bug.

[elpidioassinaturas]

Doc comment added in eebe037, as the rule asks. cube.open runs on the UI thread as stac.addCube does on main: the STAC search and the per-tile reads that cube creation already did aren't on a background path yet, and cube.open moves with them. What this PR adds there is bounded. The licence is at most 1 MB under the blocking reads' timeout, and it is read once a run after a read succeeds. The range sample is the newest file of up to four tiles, read at an overview. Moving stac.addCube and cube.open off the thread with progress and Cancel (#1562) is bigger than this PR, so I've left it for a maintainer to scope. Taking the licence only from the pane's background cache would leave cube.open from the CLI or Python without one, so I kept the read.

Third-party text in the repo (AGENTS.md, Assets). The ATTRIBUTION row answers the "every asset has a row" rule, which the earlier thread covered. It does not answer the rule's other clause: "No third-party … help text". This file is a 98 KB verbatim copy of JAXA's dataset descriptions, which is help text by any reading.

Options for the maintainers: trim the fixture to the few datasets the tests use (the counts in the tests would then change to match), or confirm that the rule is meant to allow a credited, redistributable copy of data used only by tests.

Confidence: medium-low. Whether this rule covers test data is a maintainer call.

[elpidioassinaturas]

Left for a maintainer, as you say. The fixture is JAXA's own catalog, which JAXA's terms allow redistributing with credit (the ATTRIBUTION row gives it). It is used only by tests, never shipped or shown in the app. A whole copy is what lets the tests check today's counts (how many cubes, what is left out and why). If the maintainers read the rule as covering test data, I'll trim it to the handful of datasets the tests name and change the counts to match.

Code review

Bugs

• No new correctness bugs found. I traced the range sampling (sample_range, percentile_range), the "auto" plumbing in add_cube, the credit path in open_entry, the global catalog state, and the licence cache. The earlier threads on these were checked and are addressed in the current code.

Security

• No issues found. Dataset ids are restricted to is_id, collection URLs must sit in JAXA's two buckets, and licence links must be http(s) or built from an SPDX-shaped id. No unwrap in non-test code.

Performance

• Blocking network read in cube.open (medium, inline at cube_catalog.rs:134): licence_blocking can wait up to 60 s on the command's thread, with no progress or Cancel. sample_range adds up to four more blocking COG reads. Neither has a doc comment explaining why it stays on the UI thread.

Quality

• Nit (wasm warning, low): credit() in cube_catalog.rs:131 uses s only inside a cfg(not(wasm32)) block, so wasm builds will warn about an unused variable. A let _ = s; or a cfg on the parameter would fix it.
• Test coverage (already raised): the Empty and sampling-error notices in sample_range still have no tests. This is the open thread on stac.rs, so I did not repeat it.

AGENTS.md

• Silent drop of a duplicate dataset (high, inline at jaxa.rs:195): a dataset listed twice is skipped with no note, but still counted in datasets. The test at jaxa.rs:586 asserts the silence.
• Third-party help text in the repo (medium-low, inline at jaxa_catalog.v2.md:1): the ATTRIBUTION row answers the "every asset has a row" clause. The rule's "no third-party help text" clause is not addressed, and the fixture is a verbatim 98 KB copy of JAXA's descriptions. This needs a maintainer decision.

Prior reviews

• 13 review threads were already on the PR. I left 10 alone: 7 were answered or addressed by the author and 3 were resolved, and I did not repeat them. I left the test-order thread alone because the author's answer covers it. I left the let shown shadowing and the unneeded-clone thread alone as release-pass quality points. The untested-notices thread is still open and not repeated.
• I re-raised the fixture thread on a clause its answer does not cover. I also raised the duplicate drop and the blocking read as new findings.

Major · Stability & Availability · Heavy lift

Keep automatic range sampling off the UI thread.

When a STAC catalog entry has no range, the pane runs sample_range synchronously before it adds the cube. Up to four header and value reads run in sequence, each with a two-minute timeout. Slow successful reads can therefore leave the UI unresponsive for many minutes; the first sampling error stops sampling and uses per-file stretching.

Cube creation already had blocking per-tile reads. Run the new sampling asynchronously, or apply a short overall sampling deadline and use the fallback.

Round on the latest reviews, in eebe037:

• wasm build (the failing "Web app (wasm32)" check, and the github-actions nit): credit() no longer leaves s unused in the browser build.
• Duplicate listings are now left out with a reason, so the counts add up (inline thread).
• UI thread (github-actions, and CodeRabbit's outside-diff note on sample_range): cube.open now has the doc comment the rule asks for. Its range sample runs where cube creation's own per-tile reads already ran. The sample is bounded: up to four files, each read at an overview of at most 512 px a side, under the blocking reads' timeouts. If a read fails, the sample stops and each file is stretched on its own, with a notice. I haven't added an overall deadline: a slow read that succeeds would still hold the window until it ends, so a deadline checked between files doesn't fix the stall. The fix is the background path with Cancel that [Feature]: New long-running commands run off the UI thread, and on several cores where practical #1562 sets out for stac.addCube and cube.open together, which I'd leave for the maintainers to scope.
• Tests for the sample's Empty and Err notices: answered in the thread; they need a new fixture option in rustgis-data.

Code review

Bugs

• Failed licence reads block the UI thread on every cube.open. licence_blocking (crates/tiles/src/jaxa.rs:488) now retries after any failure, and each retry can wait up to 60 s. The cube.open doc comment still says the licence is read "once a run after a read succeeds". The earlier thread on this blocking read was answered before this change, so this is new. Confidence: medium. Inline comment posted.

Security

• None found. The collection URLs are restricted to JAXA's two buckets and checked by is_id, licence links are limited to http(s) by cubes::web, and downloads are capped by download_limited/download_blocking_limited. Oversize files give an error, not a silent truncation.

Performance

• Range sampling adds to the UI-thread stall. sample_range (stac.rs) waits up to 120 s per header and per window read, for up to four files. The doc comment calls the cost "bounded" without giving the worst case. Confidence: medium. Covered by the earlier blocking thread, which I am not re-raising separately.
• Minor: jaxa_line calls cubes::jaxa_hidden() every frame, which recomputes the overlap and allocates a Vec. Cost is small. Confidence: low.

Quality

• Silent field loss in the catalog reader (jaxa.rs:277, :182). An unparseable or ≥1000 km spatialResolution becomes "not given" with no note. A repeated or malformed field key is dropped with no note. This breaks the "never silent" rule, though today's catalog probably isn't affected. Confidence: medium-high that it is silent. Inline comment posted.
• Minor: the "listed again" reason reads oddly when the first listing was itself left out. Confidence: low.

AGENTS.md

• The "never silent" item above is the main rule concern.
• No new dependencies, and the ATTRIBUTION.md row is present for the fixture. Both are fine.
• Background-path rule: cube.open runs on the UI thread with a doc comment explaining why, which satisfies the rule. The bounds are the open question above.
• Test-both-ways: the Sample::Empty and sample-Err notices still have no test, as the earlier thread noted.

Earlier concerns

• I re-raised one thread, the blocking read on cube.open, because the licence-retry change after the author's reply is new evidence.
• I left 19 earlier concerns alone: they are answered, resolved, or left for the quality pass.

Schedule a repaint while the catalog is loading

If a host opens Data Cubes in the catalog view before any map frame renders, the cache repaint waker is not installed. After the fetch completes, the pane can keep showing “Reading” and omit JAXA cubes until another interaction causes a repaint.

Suggested fix

         jaxa::Status::Reading => {
             ui.label(egui::RichText::new(tl!("Reading JAXA Earth's catalog…")).small().color(t.text_dim));

Round on the latest reviews, in 56c4863:

• Licence retry and the UI thread (github-actions, inline): only a slow failure (5 s or more) now waits 10 minutes before the licence is asked for again. A quick failure is still retried at once. Answered in the thread.
• Fields not read (github-actions, inline): each is now noted. Answered in the thread.
• Repaint while the catalog is read (CodeRabbit, outside the diff, cubesui.rs): confirmed. The tile cache's waker is set when the map view first draws, and a layout, the model builder or the catalog view return before that. So an app that starts on one of them could keep showing "Reading…". The pane now asks for a repaint every 250 ms while the catalog is being read, and while a shown entry's licence is. It stops once they are read.
• "Listed again" wording (github-actions, minor): now "listed again; its first listing, further up the catalog, stands for it", which also reads right when that first listing was left out.
• jaxa_hidden() each frame (github-actions, minor): left as is. It compares the 80 JAXA ids with the list's own, once per frame while the pane is open. I haven't measured a cost, so I'd rather not add a cache to keep in step with the list.
