feat(embeddings): AlphaEarth's years on the time slider (embeddings.addCube) (#1720) - #1749
Part of #1720: AlphaEarth's years on the time slider (embeddings.addCube). Similarity and change (§3.2 of the issue) will come in a second PR, to keep this one small.
What it does
Today embeddings.search and embeddings.add (#542) show one AlphaEarth tile for one year, and each year is a separate layer. This PR shows a tile's years as one layer on the time slider, one year per step. It reuses the mechanism stac.addCube (#559) builds on: a tile layer with time_urls, one cloud-optimised GeoTIFF per date.
embeddings.addCube{"dataset": "alphaearth", "bbox"?, "start"?, "end"?, "bands"?, "stretch"?, "name"?} adds one tile layer per AlphaEarth tile where the map is. Each layer reads its file for the year the slider is at. If the slider is off, it turns on over the years (unit: year, format: YYYY). If it's already on, it takes the years in, as stac.addCube does.
Search over the years (crates/tiles/src/embeddings.rs): aef_series / search_aef_series use the same single read of the GeoParquet index as search_aef, since its rows already hold every year. Each year's export gives its files a new name prefix (for example xdwdu82ch9yffuj03-0000008192-0000000000.tiff in 2017 and x1i7lpngfblt9wshv-0000008192-0000000000.tiff in 2024). So a tile's years are matched by place: the same CRS, and footprint corners that agree to 1e-4° (about 10 m, far below a tile's 82 km), so no rounding boundary splits a tile in two. A {YYYY} template can't describe the series. aef_tiles now shares the row parsing (aef_rows) and behaves as before.
Satellite Embeddings pane: a new All years, on the time slider checkbox. With it ticked, the search lists each tile over 2017–2025 ("AlphaEarth 2017–2025 · UTM 23S", "9 of 9 years"), and Add years hands that tile's files to embeddings.addCube (found). In the app nothing is read on the frame: the search runs off it, as before, and the layers are added without waiting for a header. The pane also gets a Cancel button while a search or read runs. It drops the result, and for a data read it releases the download.
stac.rs: the slider part of add_cube moved into cube_slider(), which both cubes use. After review it also refuses two cases it used to accept silently, for stac.addCube too: a regular slider whose span, widened to the cube's, would be more steps than it lists (MAX_STEPS, so later dates couldn't be reached), and a step longer than the cube's dates are apart (for example a yearly slider over a monthly cube), where some dates would never show. The refusal names the dates and asks for a shorter step or the slider off. The map and the slider stay as they were. docs/user-guide/web-data.md says so under data cubes.
Fix found along the way (map.setTiles): a new look (bands, range, dequantize), for example from the pane's Apply to layers, changed only the file shown. The slider brought the old look back at the next step. It now goes to every file in time_urls too, as it already did for a time_url template. This also affects stac.addCube's cubes.
Never silent
A year a tile has no file for: the layer shows nothing that year, and the command says how many tile-years are missing ("N of the M tile-years have no file in AlphaEarth's index…"). When the search read only part of the index, the notice says the gap is in the part that was read, and to zoom in (the pane hands this over as complete).
Files handed over (found) outside the years asked for, and tiles left with none, are left out, and the command says how many of each.
A partial read of the index, tiles past MAX_TILES (60), and a second file for a tile-year (the first is kept) are each reported once, with a count: as notices from the command, and on the pane's info line.
More tiles than the map has room for (MAX_TILE_LAYERS = 32) is refused, asking for a smaller area, as stac.addCube does. A cube that fails partway removes the layers it added.
Known limits and choices
Waiting: the command line, Python and the assistant wait for the one index read, plus one COG header (the first tile's latest year). That's the same as embeddings.search / embeddings.add today, and Python holds the GIL meanwhile, as for any command. The app's assistant runs its tools on the frame, so there the window waits too, as it does today for embeddings.search, layer.addUrl and the other commands that read the network; moving the assistant's tools off the frame would be a change for all of them. A plugin's command in the app (leave_downloads) is refused rather than waiting on the frame. The pane hands its own search over instead.
Web app: with found (the pane), the command works in the browser too. Without it, the search needs a blocking read, so it is refused there with a pointer to the pane.
Dates: each year is 1 January UTC (year_start_ms).
Bands: the 64 values have no physical meaning on their own, so per-band statistics over the years (cube.reduce, cube.trend) aren't offered for this cube. The useful analyses are cosine similarity and change between years, which come in the follow-up PR.
Tests
rustgis-tiles: index_rows_to_series. It covers matching years by place (including a footprint a hair off across a 1e-5° rounding boundary), another place making another tile, years outside the range, a duplicate year counted, titles and details, year_start_ms (1970, 2017, 2024), and aef_place.
rustgis-engine: parameters (13 refused addCube inputs, with the map left unchanged) and alphaearth_years_on_the_time_slider. The second checks two tiles, files in the slider's order with the AlphaEarth look plus cube=1, slider dates and YYYY, the missing-years notice, a tile hidden in a year it has no file for while the other shows, no notice when every year is there, an incomplete read's wording, a tile with no year in range left out and said, and other bands holding at every year after map.setTiles. That last check fails without the tiles.rs fix. These run offline, through found.
Checked by hand with this branch's rustgis-cli against the real index at Viçosa (MG, Brazil): embeddings.addCube gave {"tiles": 2, "years": 9, "missing": 0} in about 13 s, and share.exportMap at 2017 and 2025 gives different images.
Local runs, Windows: cargo fmt, and cargo clippy -p rustgis-tiles -p rustgis-engine -p rustgis-ui-egui --all-targets -- -D warnings clean. cargo test --lib: rustgis-tiles 428 passed; rustgis-ui-egui 789 passed (record_tests included); rustgis-engine 1225 passed, 1 failed: gdal_formats_open_when_gdal_is_installed, which fails on this PC because its GDAL is older than main needs (3.8), and is untouched here. After the first review: rustgis-tiles 428, rustgis-engine cmd:: 245, rustgis-ui-egui 789, all passed. cargo check --locked --target wasm32-unknown-unknown -p rustgis-web with RUSTFLAGS=-D warnings (LLVM's clang for zstd-sys) passes.

Walkthrough
The pull request adds all-years AlphaEarth search and embeddings.addCube. The dialog passes tile files by year to the command, which adds time-aware layers and updates the time slider. The changes also cover index limits, missing tile-years, validation, and cancellation of pending reads.
Changes: AlphaEarth cube workflow
Layer / File(s)
Summary
Build AlphaEarth year series crates/tiles/src/embeddings.rs
The index search groups matching tiles across a year range and records duplicates, omitted tiles, and index completeness. Tests cover grouping, year filtering, and metadata.
Search and add years in the dialog crates/ui-egui/src/embeddingsui.rs, crates/ui-egui/src/chrome.rs
The dialog supports all-years searches, retains each result’s year-to-file mapping, and submits year results to embeddings.addCube. It reports omitted entries and duplicates, and provides a Cancel action for pending reads.
Add cube layers and update time crates/engine/src/cmd/embeddings.rs, crates/engine/src/cmd/stac.rs, crates/engine/src/cmd/tiles.rs, docs/user-guide/web-data.md
embeddings.addCube validates and adds year-specific URLs, updates the time slider, and restores map state on errors. COG look changes apply to dated URLs. Tests and documentation cover the command and its behavior.

Merge Risk: Low · previous review 6e130
The AlphaEarth cube feature works in the main flows. Two narrow edge cases remain: an empty partial search can say there are no tiles without mentioning the incomplete read, and a cube is refused when the existing time slider already exceeds the step limit. Both are low impact, so the change is mergeable with owner awareness.

wasm build breaks under -D warnings (high confidence). series_notices in crates/engine/src/cmd/embeddings.rs is only called from the non-wasm branch of search_series. On wasm32 it is dead code, and ci.yml builds rustgis-web with RUSTFLAGS: -D warnings. Fix: gate the function with #[cfg(not(target_arch = "wasm32"))]. Posted inline with a suggestion.
Security
No new issues found. The new found input is limited to https:// addresses of at most 4000 bytes, and embeddings.addCube carries the same Network effect as embeddings.add.
Performance
Desktop command route blocks the UI thread (low–medium confidence). embeddings.addCube run directly through Session::run without found does a blocking index read and a blocking header probe. The ribbon and command search are routed to the dialog by chrome.rs, so this mostly affects the assistant, scripts and Python. embeddings.search and embeddings.add already work this way, so this extends an existing pattern. The add_cube doc comment should say why this command runs on the caller's thread, as AGENTS requires.
The pane's Cancel drops the result but does not stop the index read or the header read (low confidence). Existing searches behave the same way, so this is not new.
Quality
The missing notice wording blames the index even when the read was incomplete (moderate confidence). Posted inline.
place_key rounds footprints to 1e-5°. Two years whose footprints differ by float noise at a rounding boundary would split into two series (low confidence, about 20%). A tolerance-based match or a comment on the boundary case would settle it.
found() silently drops tiles whose years all fall outside start..end, and the returned tiles count reflects only the kept ones (low severity). This is a nit, grouped here.
AGENTS.md
Metadata-only check: the never silent rules are followed for the new notices. The tiles.rssetTiles change keeps the cube=1 and AlphaEarth flags, because the new look is derived from the layer's own address. time.goTo with date (used in the docs example) and MAX_TILE_LAYERS = 32 both check out. Option::is_none_or is within the repo's MSRV of 1.90.
The UI strings use tl! and i18n::fmt, as required.
Prior reviews: no review threads exist on this PR, so nothing was left out as already raised.
Change size
Compared with the base branch (merge base e7d26e4 to PR head fd0a0fd, the whole PR, not the latest push).
- series_notices is native only, as its one caller: the wasm32 build
passes with -D warnings.
- add_cube's doc says why it runs on its caller's thread without found.
- The missing-years notice tells an incomplete read from the index's own
gap; the pane hands its search's completeness over (complete).
- A tile handed over with no file in the years asked for is left out and
said.
- A tile's years are matched by footprints agreeing to 1e-4 degrees, not
by a rounded key a rounding boundary could split.

Thanks for the review. All of it is in a3bf404, and main is merged in 9f0338f.
wasm build (series_notices): fixed. The function is now #[cfg(not(target_arch = "wasm32"))], like its only caller. cargo check --locked --target wasm32-unknown-unknown -p rustgis-web with RUSTFLAGS=-D warnings passes locally.
Running on the caller's thread:add_cube's doc comment now says why. Without found, it waits for the index and one header on its caller's thread, as embeddings.search and embeddings.add do. The command line, Python and the assistant have no frame to hold, and they want the layers there when the command returns. The app's own routes open the pane, which searches off the frame and hands the tiles over. A plugin's command in the app (leave_downloads) is refused.
Cancel: right, it drops the result and doesn't stop the read. The existing searches do the same, and the read ends at its own limits (one index read, MAX_INDEX_ROWS). Stopping a read in flight would be a change for every search, so it isn't in this PR.
missing wording: fixed, see the inline thread.
place_key: the series are now matched by tolerance instead of a rounded key. Two rows are one tile when they have the same CRS and footprint corners within 1e-4° (about 10 m). That is well below a tile's 82 km, so no rounding boundary can split a tile. A read holds at most MAX_INDEX_ROWS rows, so comparing each row with the tiles found so far is cheap. The test now has a 2024 row 5.1e-6° off, across a 1e-5° boundary, and it still joins its tile.
found() dropping tiles with no year in range: it now says so: "N of the M tiles have no file in start–end and were left out". This is tested.
None confirmed. The found path skips the COG header probe (probe is false when found is given, embeddings.rs:242). A non-COG file from that path would fail later, as a broken layer rather than an error at add time. Low confidence this matters in practice, since pane results come from the index.
Security
None found. Handed-over URLs are restricted to https:// and length-capped, and the command carries the same Network effect as embeddings.add.
Performance
Low. same_place (tiles/src/embeddings.rs:375) allocates two strings per comparison over a linear scan of tiles. At MAX_INDEX_ROWS = 4000 that is roughly 1–2M allocations, so probably tens of ms and off the frame. A keyed map would be cleaner. Confidence low.
Quality
Nit, left for the release quality pass: the add_cube doc comment at embeddings.rs:180 says the first tile's header is read natively. On the found path it is not (see inline comment).
The PR body says footprints are matched "rounded to about a metre". The code uses a 1e-4° tolerance (about 10 m), which matches its own doc comment.
AGENTS.md
Cancel in the pane (embeddingsui.rs:581) drops the result but does not stop the index read. Moderate confidence. Inline comment posted.
found() (embeddings.rs:323) drops out-of-range years without a notice, against "Never silent". Moderate confidence. Inline comment posted.
Already raised earlier and fixed in this head, so not re-posted: the wasm dead_code on series_notices (now cfg-gated) and the incomplete-read wording of the missing-years notice (now branched on complete). That is 2 earlier concerns left alone.
Verified by reading, not by running: the year_start_ms arithmetic, the time.goTo doc example ("date": "2017" parses), MAX_TILE_LAYERS = 32, and the stac.rs refactor (cube_slider gives the same slider payloads as before).

embeddings.addCube's found dropped a file outside start..=end without a
word: a caller passing a 2016 file with start 2017 lost it silently. The
files left out are now counted and said. The pane's Cancel comment says
why a search's bounded index read is left to run on.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
I found no bugs, security problems or AGENTS.md violations in the changed lines. Two low-stakes quality items are posted inline. I checked the three earlier concerns against the head code and they are addressed; I left all five prior threads alone.
Bugs: none found. I traced the cube assembly and its undo path, the found hand-over, year_start_ms (checked against 1970 and 2017), aef_place, the map.setTiles look propagation, and the stac.rs refactor into cube_slider. Bounds are handled with get/saturating_sub/try_from, with no panics on the new paths.
Security: none found. found URLs must be https:// and at most 4000 bytes, and the command keeps the existing Effect::Network declaration.
Performance
same_place allocates two Strings per call, and aef_series calls it for every index row against every tile seen so far (up to 4000 rows). Low to moderate confidence; the cost is probably around 100 ms at worst. Inline comment on crates/tiles/src/embeddings.rs:376.
Quality
Layer names only get the place suffix when one call adds several tiles, so two tiles added from the pane share a name. Moderate confidence; not data loss, so it can wait for the release quality pass. Inline comment on crates/engine/src/cmd/embeddings.rs:270.
found() silently overwrites a year key that repeats after trimming (for example "2017" and " 2017"). Very low confidence and only reachable through the internal parameter, so I did not post it.
On the desktop, a caller that is not the pane (the assistant, for example) runs the index read on the caller's thread. The doc comment and the existing embeddings.search behaviour both say so. I did not confirm whether the assistant dispatches on the UI thread, so the AGENTS.md "Never hold the window" question stays open. Low confidence.
AGENTS.md: the new command has a doc comment explaining why it can wait, the Cancel comment is updated, the wasm gating is in place, the notices are counted, and the tl! wrappers are used in the UI. The docs example uses time.goTo with a year, which parses. No violations found.
Prior threads (5): left alone. Three are fixed in the head: series_notices is gated for wasm, the incomplete-read notice wording is in place, and outside-range found files are counted and reported. The probe-doc nit is still open and belongs to the quality pass. The Cancel thread was answered, and the comment at the Cancel button is updated.
Change size
Compared with main (merge base 41315de to PR head 7b4131f). The whole PR, by file size.

- A cube whose name a tile layer already has takes its tile's place in
it, so two tiles added from the pane one at a time can be told apart.
- add_cube's doc says no header is read with found.
- same_place compares borrowed CRS text, after the corners, with no
allocation per comparison.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
I read the full diff and the staged AGENTS.md, then checked the cross-file assumptions it depends on. Those were the add_cog probe flag, setTiles keeping cube=1, time::set honouring unit and format, download_failed, f() parsing, and the leave_downloads contexts. I could not compile or run the tests here, so compile and test results come from the author's notes, not from me.
Bugs
No confirmed bugs. The wasm dead-code thread is fixed (series_notices is gated), and the setTiles fix keeps cube=1 because the new look is derived from the old URL.
Low confidence: same_place assumes a tile's footprint corners agree across years to within 1e-4°. The tests only cover a 5e-6° jitter, and the real-index check was one area (Viçosa). A tile that falls outside the tolerance becomes a separate card with partial years ("N of 9 years"). That is visible, not a silent loss, so I'm noting it rather than requesting a change.
Security
None found. found URLs are limited to https and 4000 characters, the list is capped at MAX_TILES, and the existing embeddings.add already accepts arbitrary https URLs.
Performance
None new. The prior same_place concern is addressed.
Quality
Moderate-high, Never silent: a non-numeric start or end silently falls back to the default year range (inline comment on embeddings.rs:198, suggestion included).
Moderate, Never silent: duplicate years in a handed-over found tile silently overwrite each other (inline comment on embeddings.rs:346).
AGENTS.md
Checked and compliant: no new unwrap/expect, interface strings use tl!/i18n::fmt, the Cancel comment is updated, the wasm gating is correct, and screenshots are attached.
The blocking index read when found is absent is documented in the doc comment, as the rule requires for commands that must wait. I did not raise it.
Prior threads
7 earlier threads on this PR. All were answered with fixes or explanations, and I checked the fixes are present in the head. I left all 7 alone, since none of the new findings repeats them.
Confidence: the two inline findings are high and moderate. The footprint-tolerance note is low.
Change size
Compared with the base branch (merge base 41315de to PR head 2ad3136).
stac.rs: add_cube keeps calling cube_slider (main's slider block was unchanged), and main's range sampling (opengeos#1646) follows it.

PR #1749 adds embeddings.addCube, which puts AlphaEarth's years on the time slider, plus the matching search, pane changes, and a map.setTiles fix. I read the full diff, the staged metadata and prior threads, and the code the diff calls into (add_cog_with, tiles::add, time.goTo, f(), download_failed, and stac.rs). I found two new issues, both posted inline.
Bugs
None found. I checked the dated path in add_cog_with: a cube tile carries no time_url on this route, so the probed flag is honoured and the pane path does not block on a header read.
Security
None found. found URLs are limited to https://, at most 4000 characters, and years are range-checked. This adds no new surface beyond embeddings.add {url}.
Performance
found() checks duplicate years with Vec::contains, which is quadratic in the number of keys in a tile's years object (embeddings.rs:348). Confidence low-moderate. It only matters for a crafted, very large input.
Quality
stretch() silently falls back to 0.3 for a non-numeric stretch, the same class as the start/end thread that was fixed (embeddings.rs:169). Confidence high. This is the one finding I'd fix before merge.
Nits, left for the release quality pass:
The years field in the result counts distinct years, while missing counts tile-years. The name is ambiguous.
The pane's info line concatenates translated fragments (" · {n} more left out…"), which breaks translation.
series_notices fires before the command's refusal checks, so a refused cube can still say "tiles past the limit were left out".
AGENTS.md
The non-found path blocks the caller's thread for the index read and one header. The doc comment explains why, and embeddings.search already works this way. The lib.rs comment says the assistant also runs commands that wait, so an assistant-run addCube could hold the window in the desktop app. Confidence low; I could not confirm whether the assistant runs on the frame.
The wasm gating of series_notices and the Cancel behaviour are both consistent with AGENTS.md.
Already raised, left alone (9 prior threads): the wasm dead-code warning, the partial-read notice, the silent extra years, the duplicate-year refusal, the Cancel behaviour, the header-read doc, the same_place cost, the layer naming, and the start/end junk values. All are addressed in the proposed code or answered by the author. I did not re-raise the Cancel concern, since the author's reply defers it to #1726 and documents it, which AGENTS.md allows.
Change size
Compared with the base branch (merge base 33debef to PR head 8fe204e).
… gaps only for a cube added (opengeos#1720)

Thanks. Notes on the rest of this review (792df07, with main merged in 845f1ed, which includes #1751):
stretch: fixed, see the inline thread.
Repeated years: now a set, see the inline thread.
series_notices before a refusal: confirmed in the code. The notices were sent before the "no tiles" and "no room" refusals, so a refused cube could still say "tiles past the limit were left out". This path needs a live index read, so it can't be reproduced offline. The search now returns its notes, and add_cube says them only after the layers and the slider are in place.
years vs missing:years is the number of slider steps the cube brings (distinct years), and missing counts tile-years, as the notice says ("N of the M tile-years"). I'd rather keep the names than change the command's output now. The docs and the notice spell out each one.
Pane info line: each piece is a whole translated phrase. Only the " · " separator joins them, so a translator gets complete sentences. Merging them into one key for each combination would mean four keys for one line.
Caller's thread (AGENTS.md): same reason as embeddings.search and embeddings.add. The command line, Python and the assistant want the layers to be there when the command returns, and the doc comment on add_cube says so. In the app, the ribbon and the command search open the pane, which searches off the frame and hands its tiles over (found), so no header is read there. A plugin's command (leave_downloads) is refused rather than wait on the frame. The assistant goes through the same Session::run as embeddings.search today. If it ever runs on the frame, that would apply to every network command, not only this one.
The reason will be displayed to describe this comment to others. Learn more.
AGENTS.md (Never hold the window), confidence moderate. The justification here is that the assistant "ha[s] no frame to hold". But Session::run_leaving_downloads says the assistant's commands do wait, and the assistant runs inside the desktop app. So an in-app assistant call without found blocks the window for one index read plus a COG header (about 13 s in the PR's own check). A plugin's command in the app is refused for exactly this reason, but the assistant is not. Either refuse the waiting route in the app for the assistant too, or route the assistant to the pane as the ribbon does. The doc comment should match whichever is chosen.
The reason will be displayed to describe this comment to others. Learn more.
You're right that the in-app assistant runs on the frame, and the doc was wrong about it. The path is assistantpane::poll → with_agent → Agent::receive_result → Agent::run_tool → tools::run_with_budget → Session::run, on the UI thread with leave_downloads unset. So an assistant-run embeddings.addCube without found holds the window for the index read and one header.
The same is true today for every command that waits for the network when the assistant runs it: embeddings.search (search_aef_blocking), embeddings.add, layer.addUrl. Session::run_leaving_downloads documents it as deliberate ("the command line, scripts and the assistant run commands that wait, and see what was added"). There's no off-frame route for the assistant that this command could copy. Refusing only addCube for the assistant would leave the others as they are, and running the assistant's tools with leave_downloads or off the frame would change all of them. That belongs in its own issue, not in this PR.
71825ee corrects the doc comment and the PR text to say exactly this. I'm leaving this thread open for the maintainers' call on that wider change.
The reason will be displayed to describe this comment to others. Learn more.
Claude autofix (unclear): No code changed. The doc comment of add_cube (crates/engine/src/cmd/embeddings.rs:183-198) already says that the app's assistant runs on the frame and waits there, so it matches the code. The open question is the policy: an in-app assistant call without found still reads the index and a COG header on the UI thread, which breaks the Never hold the window rule. Fixing it needs a choice a maintainer should make: (a) refuse the waiting route for the assistant in the app, which needs an assistant-scoped signal the engine doesn't have today; (b) route the assistant's cube to the pane, as the ribbon does; or (c) move the assistant's tools off the frame for all commands, as the doc comment says. Left for a maintainer to pick.

such as 2024 rather than moving it backward when AlphaEarth dates are added.

…anded over (opengeos#1720)
- A regular slider widened over a cube's period (an hourly one over
2017-2025) could make more steps than it lists, so the cube's later
dates couldn't be reached; cube_slider now counts them and refuses,
the map and slider as they were (embeddings.addCube and stac.addCube).
- embeddings.addCube with found and complete false said nothing when
every year was there; the part read is said once the cube is added.
Both reproduced in alphaearth_years_on_the_time_slider first.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Scope: PR #1749 (embeddings.addCube, AlphaEarth years on the time slider). I read the full diff, the prior review threads, and the surrounding code: add_cog_with, tiles::set, time.goTo, and the NETWORK and cube_slider callers.
Bugs
No new confirmed bugs. The earlier threads on the wasm dead_code break, the start/end/stretch parsing, duplicate years, the hourly-slider overflow, and the incomplete-read notice are all fixed in the current code. I checked the fixes by reading them.
Security
None found. found URLs are limited to https:// and to 4000 characters, the same policy as embeddings.add's url. years parsing and BTreeSet duplicate checks are bounded.
Performance
None new. same_place now compares borrowed &strs, and the duplicate-year check is O(n log n).
Quality
No new points. The layer-name and complete wording behave as the code and tests describe.
AGENTS.md
Never silent, low-moderate (inline comment posted at crates/engine/src/cmd/embeddings.rs:226):found without complete defaults to a whole read. Partial hand-overs then get the "no file in AlphaEarth's index" wording and no part-read notice. The suggestion defaults to partial.
No unwrap/expect/panic in non-test code, no unsafe, and the new command is in the NETWORK list. cube_slider is shared with stac.addCube, so its refusal wording now covers both cubes. The new command is not in the background-command registries because it runs on the caller's thread by design, and its doc comment says so.
Ribbon: no ribbon change; the command search maps embeddings.addCube to the pane.
Already raised, left alone (17 threads): the in-app assistant waiting on the frame, found-route info-line-only reporting, the complete-related notice, the SAME_PLACE tolerance (answered with index measurements), the bands-only look copy across all dates (answered: cubes never differ per date), the Cancel that doesn't stop the index read, the pane layer naming, the same_place cost, the years quadratic check, the hourly-slider overflow, and the series_notices wasm gate. None of the code they point at has changed in a way that reopens them.
I checked the docs example against the code: time.goTo {"date":"2017"} is accepted by parse_input.

…tes (opengeos#1720)
A regular slider stepping longer than the cube's spacing (two years over
yearly files) holds two dates in one window, and apply_time shows the
later one, so the other is never shown. cube_slider now walks the
widened slider's steps and refuses, naming the dates, when any is never
shown; the map and slider as they were. Reproduced in
alphaearth_years_on_the_time_slider first.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Refused cube leaves the view moved: add_cog_with zooms on the first tile when the map was empty, and undo doesn't restore the view, so a cube_slider refusal leaves the camera on the cube while the doc and test say the map is unchanged. Confidence low-moderate. Inline comment posted (embeddings.rs:310).
Later tiles on the command route are never header-probed (only the first tile, and nothing on the found route). A non-COG file among later tiles gets added with no warning. Confidence low; AlphaEarth files are all COGs, so this is probably theoretical.
Security
None found. found URLs are limited to https:// and 4000 bytes, the same rule as embeddings.add. found is an internal parameter, but it is reachable through the assistant, and addCube carries the Network effect, so approval still applies.
Performance
None raised beyond the earlier threads. The BTreeSet repeat check and the borrowed same_place comparison were already fixed.
Quality
stac.rs:1187: the PR body says the move into cube_slider() has "no behaviour change", but the helper now refuses widened hourly spans and unseen dates for stac.addCube too. The refusal may well be right, but the PR body and the stac.addCube docs should say so. Confidence medium-high. Inline comment posted.
embeddings.rs:223: with found, bbox is silently ignored, and complete is ignored without found. Confidence medium, low severity. Inline comment posted.
Nits, left for the release quality pass: the result's years field counts unique years rather than tile-years and isn't documented; ps(p, "name") silently falls back to the default for a non-text name; and the notices are plain English format!. These match existing engine commands.
AGENTS.md
Never crash: no new unwrap, expect, or unchecked indexing in non-test code. Hostile-input cases are covered by the parameters test.
Never silent: covered by the notices and tests, apart from the points above.
Never hold the window: the assistant route still waits on the frame for the index read and one header. This was raised in an earlier thread and the author answered that it belongs to a separate issue. I did not re-raise it.
Translatable text: the new pane strings are wrapped in tl! or i18n::fmt. The Cancel label on the pane is tl!("Cancel"), not tl!("Cancel") plus i18n::fmt, which is fine.
Cancel: the pane's Cancel stops only the Data download. Search and series reads keep running, which an earlier thread already raised. I left it alone.
Wasm: the series_notes gate and the search_series wasm branch look right.
I left 20 earlier review threads alone because they were already raised and answered. The complete default, the assistant's on-frame wait, the search Cancel, the matching tolerance, and the hourly-slider edge case are among them.

…en dates (opengeos#1720)
The data cubes section gave a shorter step as the way past both refusals; past the 20,000-step limit it takes a longer step or a shorter period, as the refusal itself says.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
I found no new bugs, security problems or AGENTS.md violations in the changed code, so I posted no inline comments. This was a read-only review: nothing was built or run.
I traced the risky paths against the code they call:
Slider reachability: the check in cube_slider (crates/engine/src/cmd/stac.rs) matches how apply_time picks a date from a window (crates/map/src/tiles.rs), so a cube date that passes the check does show.
time.set: it keeps the existing unit and interval when they are omitted, so the regular-slider branch doesn't silently change them.
Header reads: the first tile's header is probed twice, but the second read is served from the cache that probe_blocking fills, so it costs nothing extra.
Pane state:found and years in embeddingsui.rs stay parallel on every path that changes them.
Input checks: the found parser, stretch() and the year parameters refuse junk without panicking.
Bugs
None new.
Security
None new. Handed-over found addresses must be https://, are length-capped, and the command carries the same Effect::Network as embeddings.add.
Performance
None new.
Quality
Cancel wording (low confidence): on a data read, the pane's Cancel calls session.download_failed, which retires the download claim with "this download failed before it completed". If a waiter exists, a user cancel reaches it as a failure. I did not confirm that a waiter exists for the pane's reads.
Length of add_cube (moderate confidence):embeddings.rsadd_cube runs about 150 lines with five error and undo paths. Splitting the per-tile loop out would make it easier to follow. This can wait for the release quality pass.
AGENTS.md
None new.
Earlier review threads
There are 26 earlier threads on this PR. Three are still open with no change: the assistant route holding the window, series_notes having no direct test, and unreadable index rows not being counted. The other 23 are resolved or answered. I left all 26 alone and did not repost any of them.

Compared: the whole PR against main (merge base a411d53 to PR head 6e130d9).

I found no bugs or security problems in the changed code. The remaining points are nits, grouped below, and I posted no inline comments. I did not compile or run the tests (no shell here), so this is a read-through of the diff and the surrounding code.
Bugs: None found. Checked: cube_slider's widened-slider step check against time::steps, TimeSlider::window and time::set (unit and interval are kept when omitted, so the checked steps match what gets set). year_start_ms against the Hinnant algorithm, with 1970 = 0. stac.rsdates is already sorted and deduplicated at lines 1036–1038, so the "dates" count in stac.addCube's output does not change. time.goTo accepts date, as the docs example uses it.
Security: None found. found URLs must be https://, capped at 4000 bytes, and bounded in count. The command declares the Network effect, so it waits for approval as other network commands do.
Performance: None worth raising. same_place is bounded by MAX_INDEX_ROWS, and the thread already discusses it.
Quality (confidence high that these are accurate; low severity; left for the release quality pass):
embeddings.rsfn stretch: the body binds let stretch = …, which shadows the function name. Renaming the local would read better.
embeddings.rsadd_cube runs about 150 lines covering validation, search, layer adds, slider and notices. Splitting out the notice block would make it easier to review.
Low-confidence observation:embeddings.rsaef_place returns None when a file name has no -, and then the tagged layer name falls back to the base name, so two tiles could share a name. Real index files always contain - (confidence low that this is reachable).
AGENTS.md: No new violations found in the changed lines. The "Never hold the window" concern for the in-app assistant, and the fact that Cancel does not stop the index read, were both raised earlier and answered, so I left them alone.
Prior reviews: 26 review threads on this PR. 16 were fixed, 1 was withdrawn, and 9 were answered without a code change. I did not re-raise any of them. The "assistant can supply found without complete" point is in the answered complete-default thread, so I left it alone.

No new blocking findings. I read the full diff, the base-branch AGENTS.md and the 26 earlier review threads, and checked the new logic against the code it depends on: the time-slider helpers, time.set, TileLayer::apply_time, the cube commands, add_cog, and the AlphaEarth index read. I did not compile or run the tests, since this review had no shell. I posted no inline comments because nothing I found clears the bar for one.
Bugs
None confirmed. The new cube_slider check matches the tile layer's rule (the latest date in [from, to)). time.set keeps the existing unit and interval when they are omitted, so the widened-span checks use the same step grid the slider will use. stac.addCube already sorts and dedups its dates before the call, so its reported count does not change. Confidence: high.
Security
None new. found URLs must be https://, are length-capped, and reach the map the same way embeddings.add's url does. found and complete are marked internal, as the existing command model already allows. Confidence: moderate.
Performance
None new. The first-tile probe and add_cog's header read share with_info's cache, so the header is fetched once. The same_place cost was raised earlier and answered. Confidence: high.
Quality
Nit: the pane's info-line fragments (" · {n} more left out: zoom in for them", and the duplicate-year note) are translated as separate fragments, so translators cannot reorder them. Confidence: low. Suitable for the release quality pass.
Nit: cube_slider(s, dates, fresh: &Value) takes an untyped JSON "fresh" object from its two callers. A typed parameter would be clearer. Confidence: low.
AGENTS.md
Open thread at crates/engine/src/cmd/embeddings.rs:189 (unresolved): an assistant-run embeddings.addCube without found still waits on the UI thread for the index read and one header. The author's reply defers the policy choice to a maintainer, and the code has not changed, so I left it alone. Confidence: high that it remains in tension with "Never hold the window"; the fix is a maintainer decision.
Answered and left alone: pane-only reporting of dropped and duplicates; complete defaulting to a whole read for found.
I raised none of the 26 earlier concerns again. The tests named in the PR body (index_rows_to_series, series_notes_say_what_a_search_left_out, alphaearth_years_on_the_time_slider) cover the behaviour I checked.

Thanks @elpidioassinaturas, this is a clean way to get AlphaEarth's years onto the time slider: one index read, tiles matched by place, and the stac.addCube machinery reused instead of copied.
What I checked: read the full diff in context (add_cog_with, apply_time, TimeSlider::window, time::steps), merged main into the branch (no conflicts), and ran the embeddings, STAC, time and tiles tests plus clippy on the merged head. All pass, and CI is green. The earlier red Test (ubuntu-latest) run was archive_render_revision::a_reload_between_series_pages…, a tile-timing test this PR doesn't touch; it passes on the merged head.
The only change I pushed is the merge of main (1c86bc6).
Two notes, neither blocking:
cube_slider now refuses a stac.addCube cube when a regular slider's step is longer than the cube's dates are apart. That is stricter than before for STAC cubes, but the refusal says what to do and the docs cover it, so I'm fine with it.
The open thread on the in-app assistant waiting on the frame: this matches what embeddings.search, embeddings.add and layer.addUrl already do there, so it shouldn't be solved for this one command. It is left open as a separate, wider question about running the assistant's tools off the frame.

Part of #1720: AlphaEarth's years on the time slider (
embeddings.addCube). Similarity and change (§3.2 of the issue) will come in a second PR, to keep this one small.What it does
Today
embeddings.searchandembeddings.add(#542) show one AlphaEarth tile for one year, and each year is a separate layer. This PR shows a tile's years as one layer on the time slider, one year per step. It reuses the mechanismstac.addCube(#559) builds on: a tile layer withtime_urls, one cloud-optimised GeoTIFF per date.embeddings.addCube{"dataset": "alphaearth", "bbox"?, "start"?, "end"?, "bands"?, "stretch"?, "name"?}adds one tile layer per AlphaEarth tile where the map is. Each layer reads its file for the year the slider is at. If the slider is off, it turns on over the years (unit: year,format: YYYY). If it's already on, it takes the years in, asstac.addCubedoes.crates/tiles/src/embeddings.rs):aef_series/search_aef_seriesuse the same single read of the GeoParquet index assearch_aef, since its rows already hold every year. Each year's export gives its files a new name prefix (for examplexdwdu82ch9yffuj03-0000008192-0000000000.tiffin 2017 andx1i7lpngfblt9wshv-0000008192-0000000000.tiffin 2024). So a tile's years are matched by place: the same CRS, and footprint corners that agree to 1e-4° (about 10 m, far below a tile's 82 km), so no rounding boundary splits a tile in two. A{YYYY}template can't describe the series.aef_tilesnow shares the row parsing (aef_rows) and behaves as before.embeddings.addCube(found). In the app nothing is read on the frame: the search runs off it, as before, and the layers are added without waiting for a header. The pane also gets a Cancel button while a search or read runs. It drops the result, and for a data read it releases the download.stac.rs: the slider part ofadd_cubemoved intocube_slider(), which both cubes use. After review it also refuses two cases it used to accept silently, forstac.addCubetoo: a regular slider whose span, widened to the cube's, would be more steps than it lists (MAX_STEPS, so later dates couldn't be reached), and a step longer than the cube's dates are apart (for example a yearly slider over a monthly cube), where some dates would never show. The refusal names the dates and asks for a shorter step or the slider off. The map and the slider stay as they were.docs/user-guide/web-data.mdsays so under data cubes.map.setTiles): a new look (bands,range,dequantize), for example from the pane's Apply to layers, changed only the file shown. The slider brought the old look back at the next step. It now goes to every file intime_urlstoo, as it already did for atime_urltemplate. This also affectsstac.addCube's cubes.Never silent

It covers matching years by place (including a footprint a hair off across a 1e-5° rounding boundary), another place making another tile, years outside the range, a duplicate year counted, titles and details,year_start_ms(1970, 2017, 2024), andaef_place.rustgis-engine:parameters(13 refusedaddCubeinputs, with the map left unchanged) andalphaearth_years_on_the_time_slider. The second checks two tiles, files in the slider's order with the AlphaEarth look pluscube=1, slider dates andYYYY, the missing-years notice, a tile hidden in a year it has no file for while the other shows, no notice when every year is there, an incomplete read's wording, a tile with no year in range left out and said, and other bands holding at every year aftermap.setTiles. That last check fails without thetiles.rsfix.
