feat(ui): report linked files changed on disk and offer Reload Data (#1477) - #1804
When another program changes a linked file, the desktop app now says so and offers Reload Data. Nothing is reread until the user chooses. This is PR 3 of #1477; #1505 added layer.reloadData and #1504 added map.reloadTiles. Every reload goes through ui.reloadData or map.reloadTiles. This PR adds no command, crate, dependency or .rgis field.
What is watched (desktop only, all maps of the open project):
linked layers, editable GeoPackage tables and local PMTiles/MBTiles archives;
GDAL/DuckDB layers at their original file, not the conversion.
Zarr stores and File Geodatabase folders are not monitored. Their Layers row tooltip says "Folder source — changes are not monitored. Use Reload Data." Remote and in-memory data are not watched.
How changes are found.rustgis_engine::observe holds one shared metadata signature. It is extracted from the archive landing check in repair.rs, which now uses it too. It records size, modification time and file identity (dev/inode/ctime on unix, creation time on Windows), plus companions:
SQLite files: -wal and -journal. An empty -wal counts as absent, and -shm is never watched.
Shapefiles: what the reader reads or sizes. That is lowercase .dbf, .shx and .prj, and all eight ASCII spellings of .cpg. This narrows the plan's "existing case variants" line to what shp.rs, read_prj and dbf::try_read_cpg actually open.
MapInfo: the .mid beside a .mif, in the spellings rustgis_data::io reads.
DuckDB: the database's .wal, where commits not yet checkpointed sit (the DuckDB conversion's cache key counts it too).
Raster sidecars (.aux.xml, .prj) are not watched; the user guide says so.
A scan runs every 5 s and when the window regains focus, on a thread of its own, one at a time. Targets reading the same absolute, lexically normalized path are grouped; links are not resolved. A change is offered only after two scans in a row agree. Missing and unreadable files are visible states that clear on a good check.
What the user sees (crates/ui-egui/src/diskwatch.rs):
A non-modal "Changed on disk" window lists each affected file.
Each layer or archive reading it gets its own Reload Data, labelled with map and layer. Repair Data Source… replaces it when the file is missing.
Reload Data activates that map first and goes through the existing dirty-GeoPackage confirmation.
Not Now hides the window for that observation only. The row keeps its mark, and a newer change notifies again.
Layers-pane rows show (changed on disk), (missing on disk) or (can't be checked).
Monitor state never dirties the project or adds an undo step.
Acknowledgement:
A reload acknowledges what its file held as its own read started: the app reads that file's metadata once when the read begins (readjob::start, the synchronous path, and before Discard Edits), kept per target and dropped if the read fails or never runs. A write during the read stays marked; a reload whose observation isn't known leaves the mark.
Saves and exports by RustGIS itself: just before gpkg.saveEdits or an export into a watched file runs, and again right after it succeeds, the app reads that one file's metadata (diskwatch::before_write / wrote; a background export does the same at start and landing). Once two scans agree, the later one started after the write, targets whose data matched the pre-write state take the post-write state as theirs, except layers the write didn't refresh: other layers on the table written (the table name resolved and trimmed as the engine does), or every layer on a single-dataset file an export replaced. Layers that read a written GeoPackage table in place aren't left marked, since the command re-reads them (gpkg::reset_sources). An outside change just before or just after the save, or between two saves, is still offered. Scans of a file an export is writing into are ignored until the export lands. A save that wrote nothing isn't a write.
Results for removed, replaced or repaired targets are dropped, and so are those for another project.
Baseline (a decision, stated as a limit). A target's baseline is its first scan, run as soon as it appears. Layers carry no file signature, and adding one would mean changing the open paths of SourceLayer, RasterLayer, GpkgEdit and archives. As a result, a write made while a layer is being opened, before that first scan, is not reported. A write that keeps size, modification time and identity is not seen either. Manual Reload Data stays available, and the user guide states both limits.
A reload, save or export run from a script, a model, the AI Assistant pane, the file bridge or the CLI doesn't go through the app's dispatch, so it doesn't clear the mark or count as RustGIS's own write (an archive reload from an attached MCP client does clear it); the user guide says so. Docs: docs/user-guide/index.md (Reload Data) and maps.md (archives). The item is removed from ROADMAP's Add data list, and GEOLIBRE_PARITY marks it done within its Partial item.
Relation to #1753 (source.syncState). That record (rustgis_data::sync) is a different tool: it covers Shapefile and GeoJSON layers read whole, hashes every part of the file and the rows, and answers on request whether edits or the file changed, as the first step of publishing edits back (#1385). This monitor covers every linked local source and archive, streamed or not, polls metadata only and offers Reload Data. Hashing whole files every 5 s isn't an option, so the two don't share a baseline; a later change could seed this monitor's baseline from that record for the layers that have one.
Testing
cargo xtask ci on the head: exit 0.
cargo build --target wasm32-unknown-unknown -p rustgis-web on the head: exit 0.
New tests:
diskwatch::tests: table-driven state machine fed injected observations. It covers two-scan promotion, per-target reload, acknowledging only what a reload's own read started with (two reloads queued with a change between them, a change no scan has seen yet), Not Now per observation (and cleared once the file is back), missing/unreadable/reappeared, self-write (mid-write scan, pending earlier change, an unseen outside change right before or after a save, two saves on one table, layers left stale), removed/replaced/repaired targets, same-path archives, and hostile paths.
App tests with real files: opening is not a change, an outside replacement is marked and notifies, Reload Data clears it, RustGIS's own gpkg.saveEdits stays unmarked; a real share.exportTable replaceTable leaves the layer on that table marked and an untouched layer unmarked; a background export through exportjob::start/land leaves a sibling table's layer unmarked; two reloads queued off the frame through readjob, the second refused by the engine, leave a later change marked until a fresh reload; a scan that never answers is said once and no second scan starts over it.
observe::tests: real-filesystem tests for SQLite and DuckDB sidecars (including -shm ignored and the link case) and Shapefile and MapInfo components.
In the app (ui_shot with watchFiles and readsOffFrame, temporary fixtures). These ran on the first commit, before the review fixes to save and reload acknowledgement; the app test above covers those paths on the head.
A streamed FlatGeobuf opened in two layers of one map and a layer of a second map gives no notice on open.
After replacing the file with a copy, all three rows are marked and one window lists three per-target actions.
Not Now hides the window and the marks stay. A reload clears only that layer. A new change notifies again. Reload Data from the window reloads only its target.
Deleting the file shows "(missing on disk)" with Repair Data Source…. Restoring it shows it changed.
Reload draws the moved point with the same style and camera.
An edited GeoPackage changed outside reaches the "Inserts: 0; updates: 1; deletes: 0." confirmation from the window.
An MBTiles archive replaced outside is marked, and reloads with the new tile and "Archive credits v2".
A RustGIS gpkg.saveEdits raises no notice.
UI evidence
New UI (after only), from ui_shot:
A FlatGeobuf read by two layers of one map and one of a second map, replaced outside RustGIS:
After Not Now the rows stay marked:
The file deleted:
An edited GeoPackage and an MBTiles archive changed outside; Reload Data on the GeoPackage asks before discarding the edit:
After Reload Data, the moved point with the same style and camera:
Desktop RustGIS monitors linked local files and tile archives for changes, including relevant database sidecars. Status indicators and notifications identify changed, missing, or unreadable sources.
Choose to reload or repair an affected source, or dismiss its notice. Changes made through RustGIS are distinguished from external edits; monitoring checks periodically and when the window regains focus.

Walkthrough
The desktop app now monitors linked local files and tile archives for on-disk changes. It reports changed, missing, or unreadable sources and provides reload, repair, and dismissal actions. The engine records metadata observations, including selected source and archive sidecars.
Changes: Desktop file watching
Layer / File(s)
Summary
File observations and archive freshness crates/engine/src/observe.rs, crates/engine/src/lib.rs, crates/engine/src/cmd/repair.rs
The engine records metadata observations for local sources and archives, including selected SQLite sidecars. Archive candidate creation checks whether the archive changed during the read.
Monitor targets and stable scans crates/ui-egui/src/diskwatch.rs
The desktop monitor tracks linked layer sources and tile archives across maps. It scans on a schedule and when the window regains focus, and settles repeated observations before reporting status.
The app enables and runs file watching, connects reload commands to the monitor, and tracks supported writes and exports. Notifications provide reload, repair, and dismissal actions. The UI script adds a watchFiles option and file copy and removal commands.
Status display and feature documentation crates/ui-egui/src/panes.rs, docs/user-guide/index.md, docs/user-guide/maps.md, GEOLIBRE_PARITY.md, ROADMAP.md
Layer and tile rows display disk status. The guides and project tracking documents describe monitoring behavior and its limits.

Merge Risk: Low · up to 5d838
Monitoring is opt-in, user-initiated, and does not modify project data. One narrow gap remains: after a GeoPackage export, a layer that failed to reopen the new table loses its changed-on-disk mark and shows only a one-time error notice. This is a bounded awareness issue and can be fixed in a follow-up.

Full details: Linked Issues check
Explanation
[#1477] This PR is PR 3 of #1477: change detection and notifications. PR 1 and PR 2 (manual layer and archive reload, #1505 and #1504) are already landed. The reviewed head implements the PR 3 coding requirements:
Detection: ui-egui/src/diskwatch.rs polls metadata of linked local layers, editable GeoPackage tables, and local PMTiles/MBTiles archives every 5 s and on focus regain. The scan runs on a background thread. A change is offered only after two agreeing scans.
Companions: engine/src/observe.rs covers SQLite -wal and -journal (not -shm), Shapefile .dbf, .shx, .prj, .cpg, MapInfo .mid, and DuckDB .wal. The later DuckDB .wal change extends the same observation logic.
Notification: a non-modal "Changed on disk" window lists each affected target. Each target has Reload Data. Repair Data Source is shown for missing files. Not Now hides the window for the current observation only. Layers-pane rows show the status.
No automatic reload. Reloads go through the existing ui.reloadData and map.reloadTiles path, which keeps the dirty-GeoPackage confirmation.
Self-writes (gpkg.saveEdits, exports) acknowledge only targets whose data matched the pre-write state. Other stale targets stay marked.
Folder sources (Zarr, File Geodatabase) are not monitored. Remote and in-memory data are not monitored. The monitor is excluded on wasm.
Tests cover the state machine, real-filesystem observation, app flows, and a wasm build (reported exit 0).
The issue entry points for context menus, Data › Data Source, and Command Search belong to the manual reload work of PR 1 and PR 2. This PR does not add them. The notice action covers this PR's notification scope. Evidence limit: this assessment relies on the supplied PR summary and the reported validation. No additional source inspection was made.
Full details: Out of Scope Changes check
Explanation
[#1477] Each changed area supports linked-file monitoring:
crates/engine/src/observe.rs and lib.rs: shared metadata signature. repair.rs uses it in place of its former local archive-check code, so the logic is not duplicated. The DuckDB .wal addition is part of the same companion-file detection.
crates/ui-egui/src/diskwatch.rs, lib.rs, readjob.rs, exportjob.rs, panes.rs, reloaddata.rs (visibility only): monitor state, reload, save and export hooks, and Layers-pane status. These are the integration points the feature needs.
apps/rustgis/src/main.rs: enables watch_files.
crates/ui-egui/examples/ui_shot.rs: watchFiles, copy, and remove script options used for the UI evidence.
docs/user-guide/index.md and maps.md: document the feature and its limits.
ROADMAP.md and GEOLIBRE_PARITY.md: record the feature. The roadmap item is removed because this PR is the last of the three PRs in the issue plan.
No unrelated dependency, crate, command, or .rgis field change appears in the supplied summary. Evidence limit: this assessment relies on the supplied PR summary. No additional source inspection was made.
Full details: Description check
Explanation
The description follows the repository template and is thorough. It has a Summary that explains what changes and why, and it links the work to the scope of issue #1477. It has a Testing section that lists the commands run (cargo xtask ci and the wasm32 build), the new unit, app, and real-filesystem tests, and the ui_shot manual scenarios. It has a UI evidence section with before-free, after-only screenshots, which fits the new UI. Its Related issue section reads 'Closes #1477'. The template asks for a 'Part of' or 'Closes' reference, and this satisfies it. The description also states limits and the decisions taken, which helps reviewers. The only gap is that the screenshots are linked by URL, which reviewers can open. No required section is missing, so the check passes.

I read the full 1,777-line diff, the base-branch AGENTS.md, and the surrounding source. There are no prior review threads, so no earlier concerns were skipped.
Correction to my own posts: my first inline comment landed on diskwatch.rs:726, which is inside the test module, not on the snapshot code. I can't delete it from here, so please dismiss it. The correct comment is on line 206. The 726 comment repeats the 206 text.
Bugs
A second reload request can clear a change the reload didn't read (diskwatch.rs:206, confidence about 55%). Reload asks keep one snapshot per target, and the second ask overwrites the first. With two queued reloads of one layer, the first landing acknowledges the second ask's state while showing stale data. Fix: take the snapshot when each read starts, or key it by a per-ask token.
Security
None found. The monitor only reads metadata, and archive paths are local-only (archive_file). Remote and in-memory data are not watched.
Performance
Nothing significant. The scan runs on its own thread, one at a time, every 5 s. Save and export add one or two metadata reads on the UI thread. That is constant-time, so I'm not raising it.
Quality
Monitor can stop silently (diskwatch.rs:430, confidence about 40%). A spawn failure only logs, and a hung scan (w.scan stays Some) blocks all later scans with no notice. Both should surface as a notice or a "can't be checked" state.
Lower-confidence notes, not posted:
key() normalises .. lexically. Two different files under a symlink can share one key, and the scan uses only the first target's path, so the other file is never observed. This needs a symlink plus .. in a linked path.
If an export fails after partly writing a watched GeoPackage, the scans were suppressed during the export and nothing acknowledges the write. The partial write is then reported as an outside change.
docs/user-guide/index.md has awkward line wraps in the new section.
Per AGENTS.md, these style points can wait for the release quality pass. I did not post them inline.
AGENTS.md
Checked against the base-branch rules. Found no unwrap/panic in non-test code and no unsafe. The new UI strings are wrapped in tl! or i18n::fmt. The diskwatch, readjob and exportjob references are native-only, so the wasm build is not affected. Background-work and cancel rules are unchanged, since no new background command was added.

I found no crash, data-loss or security defects. The logic checks out on the paths I traced: off-frame reload completion does reach diskwatch::ran, reloads refused by the dirty-edit dialog don't acknowledge changes they didn't read, readjob and exportjob are gated out of wasm, and clippy.toml allows panics in tests. Three findings were posted inline.
Performance
While a scan is stalled, tick requests a repaint every 100 ms with no end, so an idle app repaints about 10 times a second (diskwatch.rs:426). Confidence about 75%.
reading, before_write and wrote run a synchronous stat on the UI thread, which can block on the same hung mounts the stall handling is built for (diskwatch.rs:486). Confidence about 45%.
Never silent
said_stalled and said_failed are never reset within a session, so a second stall after recovery is not reported (diskwatch.rs:406). Confidence about 60%.
Bugs
None found at a confidence worth posting.
Security
None found. key(), look() and Observation handle hostile paths without panics, and the tests cover them.
Quality (grouped nits, left for the release quality pass)
The new user-guide paragraph in docs/user-guide/index.md (about lines 1862–1874) has uneven line wrapping, with some lines far over the repo's width.
Monitor::track drops targets but not their reading entries, so a reload that never lands for a removed target leaves a small entry behind. This is bounded and harmless.
AGENTS.md
Metadata reads on the UI thread are covered by the Performance comment above.
The user-facing strings I checked use tl! or i18n::fmt. No vendor assets were added. Screenshots are GitHub attachments, which docs/contributing.md permits.
Already raised, left alone: 9 earlier concerns in the prior threads (the repair-guidance text, the overlapping-reload race, the stalled-scan notice, the archive identity, the missing-file check, and the off-frame queue test). The off-frame test gap is still open, but the author's reply addresses it at the monitor level, so I didn't re-post it. I checked the author's claims against the code where I could, and the fixes they describe are present.
Change size
Compared with main (merge base b373948 to PR head f685f30), the whole PR.
CodeRabbit's two findings outside the diff range (review on f685f30):
Keep other editable layers marked after a save: fixed in 7206931 and 7142754. A save or export acknowledges only the layers it refreshed, so another layer on the written table (or on a single-dataset file an export replaced) stays marked.
Clear a dismissal when its status recovers: fixed in 7206931 and 7142754. A Not Now clears once the file is present and up to date again, so a later missing episode notifies; a file missing since it was first seen keeps its Not Now.
The reason will be displayed to describe this comment to others. Learn more.
Test gap (confidence: high): the desktop's background export path has no test.
On the desktop, a GeoPackage export runs through exportjob::start, and its acknowledgement happens here in land → diskwatch::wrote. None of the new tests reach this path. the_app_marks_an_outside_change… and an_export_leaves_the_layers… use app.run("share.exportTable"), which is synchronous and never touches exportjob. The ui_shot evidence was captured before the review fixes.
The before snapshot is taken at start and the result at landing. A test should run a background export into a watched GeoPackage, with a layer reading a different table in that file, and check that (a) the export's own write is not reported, and (b) the sibling layer is not flagged either. Ideally it should also cover the readjob path: readjob::start → run_read → diskwatch::ran, with a second reload queued behind the first.

Fixed in b0e60d0: a_background_export_marks_only_the_layers_it_left_stale runs an export through exportjob::start/land into one GeoPackage table and checks the layer on a sibling table stays unmarked; a_queued_reload_that_is_refused_leaves_a_later_change_marked drives two reloads through the off-frame readjob queue.

Possible transient false "Changed on disk" after a background export (confidence: about 30%).
While an export runs, tick drops every scan result for the exported file. observed is never called, so source.last stays at the pre-export observation. When the export lands, wrote sets next_scan = w.scans + 1.
A scan that was in flight across the landing completes after export_job is cleared, so it is observed normally. Its number is below after, so it can't acknowledge. The next scan then agrees with it, and the result is settled at the post-write state while targets still have the pre-write baseline. The status is Changed until the following scan acknowledges, about 5 s later. That includes a sibling layer on another table in the same GeoPackage, which the export did not touch and which the design says should not be marked.
This needs a scan still in flight at landing, so it is most likely on a slow network drive. The fix is either to hold the scan results taken during the export and re-observe them in order at landing, or to make wrote ignore any scan number at or below the one in flight when the export landed. A test that runs a scan across the export's landing would settle it.

Fixed in b0e60d0: a RustGIS write is acknowledged once two scans agree and the later one started after it, so a scan in flight across the write no longer leaves a false mark. A monitor test covers the in-flight case.
Possible transient false "Changed on disk" after a background export into a watched GeoPackage. Scans taken during the export are dropped, so the first post-landing agreement can settle without acknowledging. The result is a sibling layer flagged for about one scan interval. Requires a scan still in flight at landing, so most likely on a slow network drive. Confidence: about 30%. Inline comment on crates/ui-egui/src/diskwatch.rs:423.
A failed save or export that still changed the file (SQLite can rewrite the main file on rollback) is not acknowledged, so it can later show as an outside change. Acknowledgement only happens on success, which is conservative, so this is noise rather than silent loss. Confidence: about 30%. Not posted inline.
Security
None found. The monitor only reads metadata (metadata, is_dir, canonicalize), never opens or reads file contents, and is not blocked by FIFOs or devices. Project paths are not interpolated into commands.
Performance
No new finding. The UI-thread stat calls in reading, before_write, wrote and exportjob::land are already raised in an earlier thread that still applies. I left it alone.
Quality
The background export landing path (exportjob::land → diskwatch::wrote) and the queued-reload path through readjob have no tests. The app tests use synchronous exports and reads_off_frame = false. Inline comment on crates/ui-egui/src/exportjob.rs:81. Confidence: high.
Nits, left for the release quality pass: docs/user-guide/index.md around line 2019 has ragged wrapping (one very long line, and .shp split onto its own line). The doc comment on Observation::source in observe.rs wraps awkwardly.
AGENTS.md
No violations found in the changed code. Panic-prone calls (unwrap, expect, panic!) appear only in test modules. New user-visible strings use tl! or i18n::fmt. Background exports go through exportjob::start. Reload acknowledgement reaches diskwatch::ran on both the sync and async paths (run_with_prepared → AppDispatch::Read). The wasm gating is consistent, with readjob and exportjob compiled only for non-wasm. The file:// concern I checked does not apply: layer readers don't accept that prefix, and archives strip it. archive_file() excludes upload:.
Earlier review threads: 10 threads were already on this PR. I left them alone: 7 are addressed on the head (the stall episodes, reload races, archive identity, Repair guidance and the repaint rate), and the UI-thread stat thread still applies but was not re-posted. The queued-reload test answer is only partly responsive, since the new test drives Monitor directly rather than the readjob queue. I folded that into the test-gap comment rather than re-posting it.

Do not mark refreshed streamed layers as stale.
If an editable layer and a streamed layer read the same GeoPackage table, gpkg.saveEdits resets the streamed source. A table-replacing export also reopens matching streamed sources. This filter still adds those layers to stale, so Monitor::observed leaves them marked changed on disk after stable scans. Keep that mark for readers that retain old data or fail to reopen; acknowledge readers the engine refreshed. (raw.githubusercontent.com)

Fixed in b0e60d0: a save or export into a GeoPackage no longer marks layers that read that table in place; the command already re-reads them (gpkg::reset_sources). Editable layers still holding old rows stay marked, and so do readers of a single-dataset file an export replaced.

@deniial00 Thanks for the fix. It handles successful refreshes, but the failed-reopen case remains.
before_write excludes streamed GeoPackage targets from stale before the export runs (crates/ui-egui/src/diskwatch.rs, Line 586). If reset_sources then fails to reopen one, the engine reports a notice, but the watcher can still acknowledge that target as unchanged.
Please retain the stale mark for failed reopenings and add a regression test for that case. I’m not marking the finding as addressed yet.

From the Claude review summary on 56d8f8c, not posted inline:
A failed save or export that still changed the file isn't acknowledged, so it can show as an outside change. It errs toward showing a change, never hiding one; left for the release quality pass (reviewed at 5d838cf).
Also in 5d838cf (local review): a DuckDB database's .wal now counts as part of the watched file, so commits not yet checkpointed are seen.
The reason will be displayed to describe this comment to others. Learn more.
Low confidence (~45%): .db is not a DuckDB name in this codebase.crates/data/src/source/duckdb.rs lists EXTENSIONS = ["duckdb", "ddb"], and its test asserts !is_duckdb_name("a.db"). Here .db gets a <file>.wal sidecar, which a .db file doesn't have. If a .db file is ever a SQLite database in WAL mode, its -wal commits are not watched at all, because that case takes the DuckDB branch and not the SQLite branch.
Suggested change: drop db from this list, so it matches the reader. If .db should be treated as SQLite, move it to the gpkg, mbtiles, sqlite branch instead.
The reason will be displayed to describe this comment to others. Learn more.
Low-to-moderate confidence (~35%): keys are case-sensitive, but macOS (default APFS) and Windows paths are not.key() lowercases nothing, so one file reached through two spellings (Data/Places.gpkg and data/places.gpkg) gets two keys. Consequences I'd expect:
RustGIS's own save or export through the other spelling isn't seen as its own write (watches(key) is false), so the file is reported as changed on disk after RustGIS wrote it.
The same file is scanned twice, and each target can raise its own notice.
I haven't verified this on a case-insensitive filesystem. Possible fix: fold case when the platform's filesystem is case-insensitive (Windows, macOS). Alternatively, compare file identity (dev and inode, or the Windows file index) when grouping. The lexical-only design is stated in the doc comment, so this may be a deliberate trade-off. If so, the user guide should say that spellings of one file are separate sources.
I read the full diff, the 14 prior review threads, and the surrounding code: the reload and landing paths in readjob.rs, the dispatch in lib.rs, and the DuckDB and reader extension handling. I did not run the tests or build; I had no shell. The findings below are what survived checking. The rest of the logic holds up: the acknowledgement, in-flight-scan, and queued-reload paths all check out against the code.
Bugs
observe.rs:134 treats .db as DuckDB and watches <file>.wal, but the codebase does not treat .db as DuckDB. A WAL-mode SQLite .db would have its -wal commits go unwatched. Confidence: low (~45%). Inline comment posted.
A failed export never acknowledges its own write (exportjob::land calls wrote only on Ok). A partial write then shows as an outside change once the scans settle. This is conservative, not silent loss. Confidence: low (~30%).
Security
No findings.
Performance
Nothing new. Metadata reads on the UI thread in before_write, wrote and reading were raised in an earlier thread and deferred by the author.
Quality
diskwatch.rs:256: key() is case-sensitive, so on macOS and Windows one file reached via two spellings gets two keys. That can misreport RustGIS's own save as an outside change and double the notices. Confidence: ~35%. Inline comment posted.
Nits, left for the release quality pass: diskwatch.rs is 1,298 lines with about 470 of them tests, so it could split into a module directory. In the a_scan_that_never_answers… test, checked_sub(STALLED * 2).unwrap() can return None on a freshly booted host. In docs/user-guide/index.md (lines 2144–2147), the paragraph wrapping is uneven.
AGENTS.md
Complied with: tl! and i18n::fmt are used for user-visible text, scans run on their own thread, the notice path goes through Session::notify, the tests cover both lossy and clean cases, and the amber token and tempfile dev-dependency exist.
Left alone: the UI-thread stat calls, already raised and answered with a deferral.
Already raised (left alone): 14 review threads are on this PR. I did not repost any of them. The two inline comments above are new concerns.

Keep a streamed layer marked if its source fails to reopen.
When a GeoPackage export replaces a table, reset_sources can report that a matching streamed layer could not reopen the new table. The export still succeeds. Line 586 excludes that layer from stale, so stable scans advance its baseline and show Unchanged even though its source is unavailable. A separate error notice does not preserve the layer’s changed-on-disk action. Acknowledge only layers that the command actually refreshed. (raw.githubusercontent.com)

Summary
When another program changes a linked file, the desktop app now says so and offers Reload Data. Nothing is reread until the user chooses. This is PR 3 of #1477; #1505 added
layer.reloadDataand #1504 addedmap.reloadTiles. Every reload goes throughui.reloadDataormap.reloadTiles. This PR adds no command, crate, dependency or.rgisfield.What is watched (desktop only, all maps of the open project):
Zarr stores and File Geodatabase folders are not monitored. Their Layers row tooltip says "Folder source — changes are not monitored. Use Reload Data." Remote and in-memory data are not watched.
How changes are found.
rustgis_engine::observeholds one shared metadata signature. It is extracted from the archive landing check inrepair.rs, which now uses it too. It records size, modification time and file identity (dev/inode/ctime on unix, creation time on Windows), plus companions:-waland-journal. An empty-walcounts as absent, and-shmis never watched..dbf,.shxand.prj, and all eight ASCII spellings of.cpg. This narrows the plan's "existing case variants" line to whatshp.rs,read_prjanddbf::try_read_cpgactually open..midbeside a.mif, in the spellingsrustgis_data::ioreads..wal, where commits not yet checkpointed sit (the DuckDB conversion's cache key counts it too).Raster sidecars (
.aux.xml,.prj) are not watched; the user guide says so.A scan runs every 5 s and when the window regains focus, on a thread of its own, one at a time. Targets reading the same absolute, lexically normalized path are grouped; links are not resolved. A change is offered only after two scans in a row agree. Missing and unreadable files are visible states that clear on a good check.
What the user sees (
crates/ui-egui/src/diskwatch.rs):Acknowledgement:
readjob::start, the synchronous path, and before Discard Edits), kept per target and dropped if the read fails or never runs. A write during the read stays marked; a reload whose observation isn't known leaves the mark.gpkg.saveEditsor an export into a watched file runs, and again right after it succeeds, the app reads that one file's metadata (diskwatch::before_write/wrote; a background export does the same at start and landing). Once two scans agree, the later one started after the write, targets whose data matched the pre-write state take the post-write state as theirs, except layers the write didn't refresh: other layers on the table written (the table name resolved and trimmed as the engine does), or every layer on a single-dataset file an export replaced. Layers that read a written GeoPackage table in place aren't left marked, since the command re-reads them (gpkg::reset_sources). An outside change just before or just after the save, or between two saves, is still offered. Scans of a file an export is writing into are ignored until the export lands. A save that wrote nothing isn't a write.Baseline (a decision, stated as a limit). A target's baseline is its first scan, run as soon as it appears. Layers carry no file signature, and adding one would mean changing the open paths of
SourceLayer,RasterLayer,GpkgEditand archives. As a result, a write made while a layer is being opened, before that first scan, is not reported. A write that keeps size, modification time and identity is not seen either. Manual Reload Data stays available, and the user guide states both limits.A reload, save or export run from a script, a model, the AI Assistant pane, the file bridge or the CLI doesn't go through the app's dispatch, so it doesn't clear the mark or count as RustGIS's own write (an archive reload from an attached MCP client does clear it); the user guide says so. Docs:
docs/user-guide/index.md(Reload Data) andmaps.md(archives). The item is removed from ROADMAP's Add data list, and GEOLIBRE_PARITY marks it done within its Partial item.Relation to #1753 (
source.syncState). That record (rustgis_data::sync) is a different tool: it covers Shapefile and GeoJSON layers read whole, hashes every part of the file and the rows, and answers on request whether edits or the file changed, as the first step of publishing edits back (#1385). This monitor covers every linked local source and archive, streamed or not, polls metadata only and offers Reload Data. Hashing whole files every 5 s isn't an option, so the two don't share a baseline; a later change could seed this monitor's baseline from that record for the layers that have one.Testing
