After another program updates a linked tile archive, RustGIS can keep drawing cached tiles and attribution. Add Reload Data to reread a local PMTiles or MBTiles archive without removing it or rebuilding its presentation.
map.reloadTiles accepts the same name/index/catalog-id selectors as archive repair, without a replacement path. It preserves the archive's settings, style, order, visibility and map camera.
Repair and reload share fresh candidate validation. Missing, unreadable, locked, truncated or incompatible files leave the existing presentation and retained cached data intact, with an actionable error and manual retry. Successful reload is one undo step; undo cannot restore externally overwritten file contents.
Native reload and archive repair validate through the existing single background-read queue with admitted caller ownership and project/map/archive/settings checks. Failed worker preparation does not fall back to synchronous archive I/O; repair success is reported only after installation.
Source-specific invalidation covers decoded tiles, metadata, PMTiles directories, resolved styles and MBTiles handles. Generation checks reject obsolete completions and obsolete pooled-handle returns without clearing unrelated archives.
The translated desktop archive context action sits beside Repair Data Source…. Local-file UI is hidden on wasm; the command remains registered and explicitly refuses unsupported local-file use. Automated callers retain the existing file-permission gate.
This is manual archive reload only: no monitoring, notifications about detected changes, new dependency or serialized project field. Windows may still refuse replacement of an MBTiles file while SQLite holds it open; this does not promise atomic replacement of an open archive.
Ordinary archive loading is intentionally stricter too: malformed/non-object/truncated PMTiles metadata, a stored metadata section over 16 MiB, or unreadable/non-text MBTiles metadata is refused rather than silently losing credits or source-layer information. Repair/reload validates every reachable PMTiles directory within explicit limits: 64 MiB stored and 64 MiB decoded index bytes, 1,048,576 entries, 4,096 directories including root, four leaf levels and 16 MiB per stored directory. Exceeding a limit refuses without eviction; tile payloads remain lazy.
Testing
Passed on verified head 0eebe727: RUST_TEST_THREADS=1 cargo xtask ci (formatting, workspace Clippy with -D warnings, the unfiltered serialized workspace suite and layering), pre-commit run --all-files, and cargo build --target wasm32-unknown-unknown -p rustgis-web with LLVM clang and -D warnings. The initial default-parallel run failed the unchanged desktop startup-marker test at apps/rustgis/src/main.rs:663; no startup code was changed and that failed run is not claimed passed.
Focused command/cache regressions cover both formats, changed pixels and attribution, unrelated-source retention, delayed stale answers, PMTiles metadata/directories, MBTiles handle generations, missing/truncated/locked/incompatible files, retry, selectors and undo. Unix coverage also replaces an open MBTiles inode.
Real command/render smoke changed red tiles to green and refreshed attribution for both archive formats, preserving presentation and camera. Undo did not rewind the external file.
Actual native ui_shot runs invoked each archive menu, failed against a temporarily missing path while retaining old tiles, then retried successfully after restoring changed archive bytes and attribution. Screenshots were inspected.
Initial feature command-only wasm smoke executed the real command in Bun: registered, explicit local-file refusal, unchanged project and no undo step. Temporary source instrumentation was removed. The full browser-app smoke stalled; no browser UI success is claimed. Native OS behavior was exercised on macOS, not Windows.
Round-2 review fixes: archive approvals bind the selected tile and its private source (redacted in review); prepared reload/repair results are rejected if the file (or an MBTiles WAL/journal) observably changed after validation, before any eviction; PMTiles validation checks cancellation per directory entry and rejects overlapping tile runs; direct relay/MCP run_command reloads/repairs validate on the existing background read worker and reply only after landing (arbitrary run/file-bridge scripts stay synchronous). Linked probes against the previous head reproduced each defect (stale approval accepted, stale result evicted retained pixels, overlap accepted, no cancellation checks, a 10.7 s blocked UI frame under an attached relay call); against the new head each flipped (relay frames ≤ 5.5 ms). Native ui_shot smokes covered a relay reload under an exclusive SQLite lock (Running/Cancel, error reply after landing with red tiles retained, green retry) and a held landing whose archive was overwritten after validation (rejected, red retained, green retry).
Integration verification exposed an unchanged desktop startup-marker test failure once; the final default-parallel run passed. An unrelated GeoLibre 1.7.1 error-prefix assertion was removed with user approval while retaining the vector-input rejection and real raster/output/save/undo coverage. ci:full is applied for GitHub macOS/Windows/release coverage; local native UI smoke was macOS only.
Round-3 review fixes: checked selector insertion, whitespace-normalized MCP archive interception, explicit-selection ownership before every archive pause, nested/memoized PMTiles run-boundary checks, and label-drag cleanup around resumed relay completion. Focused deterministic regressions and a fresh pre-push review passed. A new native ui_shot smoke inspected the integrated archive menu (including upstream Export Raster) and changed red tiles/credits to green/fresh credits at the same camera. Main integration includes upstream test(engine): the GeoTIFF tile-layer test no longer deletes an open archive (fixes main CI on Windows) #1618's Windows open-archive test fix; The full GitHub matrix at 8be9319f, including Windows x64 and ARM64, subsequently passed; the latest push starts fresh checks.
Round-4 review fixes: each archive pause binds project/map identity and rejects a changed-context suffix without dispatch; directory validation checks descendant lower bounds, including memoized references; the PMTiles writer explicitly rejects non-object metadata; docs distinguish background entry points from inline scripts. Native before/after runs reproduced wrong-map suffix mutation and malformed-index eviction, then verified explicit suffix rejection, retained red tiles on error, and green/fresh-credits manual retry after correction. Screenshots were inspected; focused regressions and the fresh six-file review passed.
Round-5 fixes and main integration: MBTiles metadata beyond 1,000 rows refuses instead of silently losing later credits; PMTiles writing enforces the reader’s 16 MiB serialized metadata limit; the native-only assertion is guarded. Main merge preserves destination-provenance checks and alternate reach outcomes alongside archive epochs. Fresh three-file and seven-overlap integration reviews approved; 408 tiles tests, 34 portable-project tests, the serialized full gate, pre-commit and normal wasm build passed. Native smoke reproduced the old attribution loss and verified refusal/retention plus corrected manual retry for both formats. An extra wasm tiles unit-test-target attempt was blocked by an unchanged native-only cache test from 53e06c699; it is not claimed passed.
Initial feature review: two fresh approvals of the original 12-file change. Approved feedback fixes and main integrations received fresh reviews before pushing. The latest complete integration review found one PMTiles filename/cache mismatch; a failing-before/passing-after regression and native filename-boundary smoke verify the fix, and the follow-up reviewer approved it. The separate user-approved GeoLibre test-only correction also received a fresh approval.
UI evidence
PMTiles and MBTiles context menus and successful reloads below. The solid red/green tiles are synthetic fixtures; the lower-right credits change with the archive. Status bars were cropped out to exclude local filesystem paths.
PMTiles: menu before reload
PMTiles: changed tiles and attribution after retry
MBTiles: menu before reload
MBTiles: changed tiles and attribution after retry
Background validation evidence
The actual native menu remained responsive with Running/Cancel while SQLite held an exclusive lock. Failure retained red tiles/credits; after unlocking, explicit retry displayed green tiles and fresh credits at the same view. The final native smoke also exercised PMTiles missing-file failure/retry with a #cube= filename and explicit kind: pmtiles (URL kind guessing is separate).

Summary by CodeRabbit
New Features
Desktop users can reload or repair linked local PMTiles and MBTiles archives while retaining layer presentation and map view. Reload rereads archive data without changing its contents; undo cannot restore overwritten file contents.
Supported assistant commands can reload or repair archives, with replies and later actions in the same batch waiting for the operation to finish.
Bug Fixes
Archive refreshes reject stale results without affecting unrelated archives. Renders and exports report errors if linked archive data changes during processing.
Invalid or unreadable archives are rejected without replacing the existing layer or source.
Documentation
Updated guides explain archive validation, platform limitations, and metadata requirements, including size and row limits.
No actionable comments were generated in the recent review.
Walkthrough
This change adds local archive reload and repair flows. It also adds archive freshness checks in cache, render, and UI paths. Desktop and relay command handling now validate and apply archive reads before state changes.
Changes: Local archive validation
Layer / File(s)
Summary
Fresh archive reads and validation crates/data/src/mbtiles.rs, crates/tiles/src/pmtiles.rs, Cargo.toml
Fresh MBTiles reads use an unpooled connection, support cancellation, limit metadata rows, and probe tile pages. PMTiles validation checks metadata and reachable index directories under aggregate limits. The SQLite dependency enables hooks.
Archive revisions and cache invalidation crates/tiles/src/cache.rs, crates/tiles/src/source.rs
Archive revisions and epochs now guard cache inserts, fetches, and resolved styles. Reload and forget paths clear archive-specific entries and keep stale work from replacing current state.
Reload and repair now flow through explicit read preparation, approval checks, and background landing. Desktop UI exposes Reload Data for archive-backed layers. Relay and MCP handling pause and resume archive reads, and the supporting tests and docs cover command gating, cancellation, stale targets, and user-facing behavior.
Render and export paths now capture archive revisions and return errors when linked archives change during the operation. UI frame, GPU tile, tilt drape, and settle paths also reject stale results before they are adopted or displayed.

Merge Risk: Low · up to 0384c
The change adds manual reload and repair for local tile archives, with revision checks that keep stale results from replacing current data. The remaining items are mostly low-impact: unbounded archive revision bookkeeping, deferred test and documentation polish, and a documented limit where a blocked filesystem read can hold the read queue. These can be accepted or handled as follow-up.

Behaviour regression on the normal open path (not only reload). The removed code read metadata with rows.filter_map(Result::ok), so one unreadable row was skipped. Now row.map_err(sql)? fails the whole archive. r.get::<_, String>(1) also errors for a NULL value, and for an INTEGER value in an untyped metadata table (rusqlite's String only accepts TEXT). An archive that drew tiles before now reports "not a readable MBTiles file".
Suggested direction: keep skipping bad rows, but count them and report one notice (AGENTS "Never silent"), so the file still opens. Confidence: medium (about 65%). I haven't run this against a real file.
Test gap: write_archive only creates typed metadata (name TEXT, value TEXT) tables, so no test covers this. Add one "lossy input gives the notice, clean input none" case with an untyped or NULL-valued row.
The reason will be displayed to describe this comment to others. Learn more.
Refusing malformed metadata is intentional: metadata names and values must be text, and silently dropping unreadable attribution would violate the loss policy. The stricter ordinary-open behavior is now documented and tested; adding lossy recovery is outside this manual-reload PR. (reviewed at 96f1d6e)
The reason will be displayed to describe this comment to others. Learn more.
Open-path behaviour change, not mentioned in the PR body or docs. Before this PR, metadata that failed to read, decompress or parse as JSON was dropped silently and the tiles still drew. Now metadata(...) errors propagate through finish, so the whole archive is refused. The same applies to parse_head (line 849), which errors when metadata exceeds MAX_BYTES (16 MiB) instead of truncating it.
Both changes are loud, which fits "never silent", but they turn a cosmetic problem (attribution or layer names) into a file that can't be drawn at all. A more proportionate option is to keep the tiles and report a notice that the metadata was dropped. Confidence: medium on the behaviour, a design call for the author. Please say which is intended, and add a test for the open path, since the new tests cover only the reload validator.
The reason will be displayed to describe this comment to others. Learn more.
Fixed in 96f1d6e: retained the intentional strict metadata policy, documented that it applies to ordinary loading as well as repair/reload, and added actual ordinary-loader regressions for malformed, non-object, truncated, compressed-invalid and oversized metadata.
The reason will be displayed to describe this comment to others. Learn more.
Same change as the comment on line 515, at its source: archives with metadata over 16 MiB now fail to open rather than loading tiles with metadata dropped. Please note this in the PR and the user guide if it is intended.
The reason will be displayed to describe this comment to others. Learn more.
Addressed with the line-515 metadata-policy finding in 96f1d6e: the documentation and ordinary-loader coverage explicitly include the 16 MiB stored-metadata limit (not an archive-size limit). Metadata is refused rather than silently truncated.
I read the full diff, the AGENTS.md from the base branch, and the surrounding code. There are no prior review threads, so I left no earlier concerns out. Three inline comments are posted.
Bugs (behaviour changes on the ordinary open path)
MBTiles metadata rows (crates/data/src/mbtiles.rs:390): one unreadable metadata row now fails the whole archive. The old code skipped it with filter_map(Result::ok). A NULL value, or an INTEGER value in an untyped table, now produces "not a readable MBTiles file". Confidence: medium (about 65%), not run against a real file.
PMTiles metadata failures (crates/tiles/src/pmtiles.rs:515): bad or undecodable metadata used to be dropped silently, with tiles still drawn. Now the archive is refused. This is loud, which fits AGENTS, but the PR body and docs don't mention it. Confidence: medium on the behaviour; the author should confirm whether it is intended.
PMTiles metadata over 16 MiB (crates/tiles/src/pmtiles.rs:849): previously truncated, now refused. Same concern as above. Confidence: high that the behaviour changed.
Security
No findings. The reload is gated: map.reloadTiles is in READS_FILES, and the assistant's approval check uses the shared reaches(), so it asks for approval. Read-only SQLite opens mean a reload cannot create a missing file.
Performance
No findings. The new epoch locks run per tile request, but they are cheap.
Quality (not posted, left for the release quality pass)
reload_archive keys archive_epochs by the raw URL, while readers use resource_of(url). They agree for ordinary paths, and diverge only for addresses containing #rustgis-* markers. Confidence: low.
pmtiles::reload_archive returns an opaque impl Sized tuple to defer drops. A named type would read better.
chrome.rs hardcodes the wasm command IDs. A small helper would be clearer.
The per-path epochs map in the data pool and the reload epochs in cache.rs only grow. The growth is small.
AGENTS.md
Test gap: write_archive only creates typed metadata (name TEXT, value TEXT) tables, and the new PMTiles checks run only on the reload validator. AGENTS requires testing both lossy and clean input for the open path. Both gaps are covered in the inline comments.
Otherwise the change follows the rules I checked. No new unwrap/panic in non-test code, wasm gates are present, the new strings use tl!, and the docs are updated.
Checked and found fine: lock ordering across the epoch, cache, archive and leaf locks (no re-entry found, including settle in source.rs); the upload path in info_ready; archive_file() excludes uploads, so the menu never offers a reload for them.
Change size
Compared with main (merge base 9ae69a3 to PR head c2aeba6).

Review comments at @crates/data/src/mbtiles.rs:
- Around line 350-351: Bound the path-generation bookkeeping in Pool.epochs so
reloads of distinct archives, including PMTiles, do not retain every historical
path; do not simply evict epochs while connections may still be in flight, and
preserve rejection of stale connections by establishing when an epoch is safe to
reclaim.
- Around line 373-376: Update the MBTiles validation around the `tile_data`
query so it decodes the sampled raster tile and rejects the replacement if
decoding fails; do not invalidate the retained-image cache until this validation
succeeds.
Review comments at @crates/engine/src/cmd/plugins.rs:
- Line 309: Add `map.reloadTiles` to the command classification used by
`touches_files` so untrusted tasks and notebooks refuse it. Keep the existing
`READS_FILES` entries and trust-check behavior unchanged for other commands.
Review comments at @crates/engine/src/cmd/repair.rs:
- Line 189: Update the archive reload flow around reload_archive so reloading a
local archive invalidates cached entries and pending reads for equivalent path
and file-URL spellings, such as /data/a.mbtiles and file:///data/a.mbtiles.
Reuse the existing path normalization and invalidation mechanisms where
available, preserving behavior for non-local archives.
- Around line 190-191: After the tile reload succeeds in the flow that updates
`s.map_mut().tiles`, cancel the pending view request associated with that
reloaded layer so late metadata cannot move the camera. Use the existing
request-matching and cancellation mechanism, and leave requests for other layers
untouched.
- Line 186: Move the fresh validation performed by archive_candidate off the
frame-processing/UI thread in the repair flow. Run it through the existing
bounded worker mechanism and apply its success or error result on the UI thread
only after the worker completes, without blocking frame processing or allowing
unbounded worker creation.
Review comments at @crates/engine/tests/portable_projects/reload_tiles.rs:
- Line 129: In the reload test, capture `s.undo_depth()` immediately before
`s.run("map.reloadTiles", ...)` and assert afterward that the depth increased by
exactly one. Keep the existing reload result and undo/redo assertions intact.
- Around line 169-170: Add a regression case to the reload_tiles tests using an
MBTiles fixture with a readable schema and complete zoom and format metadata but
an unreadable first tile page. Use rejected to assert reload fails and verify s
retains its cached data; ensure the fixture reaches the first-tile probe rather
than failing during initial file parsing.
Review comments at @crates/tiles/src/pmtiles.rs:
- Around line 775-778: Validate every referenced PMTiles leaf directory,
including its varints, before the reload path clears the tile cache; reject the
archive on a truncated varint and retain the existing cached presentation. Use
the directory-reading and parsing flow around read_file and metadata to
establish validation, preserving their existing error handling.

Included review availability: This review used your included allowance. Your plan provides up to 8 included reviews per hour; 6 remain after this review.
I read the full diff, the base AGENTS.md, and all 12 prior review threads. I traced the new archive-epoch scheme through cache.rs, source.rs, pmtiles.rs, mbtiles.rs and repair.rs, including lock order and the paths that drop callbacks. I could not build or run the tests (no shell here). I found no new defect I can confirm, so I posted no inline comments. The points below are minor and grouped.
Bugs
None new. Lock order is consistent (archive epochs, then cache, archives, leaves, infos, resolved), and no callbacks run while a lock is held. Confidence: high.
Security
None new. map.reloadTiles is now in READS_FILES (plugins.rs:309), which feeds the file-reach check at plugins.rs:396-402, so untrusted workflows refuse it. Local paths still pass check_local / mbtiles::check before any read. Confidence: high.
Performance
source::resolve runs settle(), including kept(), inside the global archive-epoch mutex for every source, web layers included (source.rs:177). Probably harmless, but it lengthens the critical section. Confidence: low.
The new archive_epochs map in cache.rs (around line 127) is never pruned, so each reloaded archive path stays for the session. This is the same growth as the Pool.epochs thread, at a new site, so I did not repeat it. Confidence: medium; severity low.
Quality
chrome.rs:977 hard-codes map.reloadTiles and map.repairTiles to hide them from command search on wasm. The id list is brittle, and hiding repairTiles on wasm is not mentioned in the PR body. Confidence: medium.
pmtiles::forget_archive (around line 405) and the new pmtiles::reload_archive (around line 416) overlap almost completely. They differ in how they treat Loading entries, which may be intentional, but a comment should say so. Confidence: high that they overlap.
The fetches_through_the_fetcher_once test (around cache.rs:3042) now re-executes the test binary to isolate global state. It works, but it is unusual enough to deserve a note. Confidence: medium.
AGENTS.md
Platform coverage: the PR changes file replacement, SQLite locking and open-handle behaviour, and the PR body says Windows was not tested. AGENTS.md asks for ci:windows (and ci:macos) on platform-specific code. Suggest adding those labels before merge. Confidence: high.
Everything else I checked conforms: no unwrap, expect or panic in non-test code; wasm cfg gates are present in read_info_local, reload_archive, reload_tiles and panes.rs; new UI strings use tl!; the docs match the commands.
Already raised (not repeated): 11 of the 12 earlier threads still apply at this head, so I left them alone: MBTiles row skipping (mbtiles.rs:390), PMTiles metadata fail-open (pmtiles.rs:515), the 16 MiB metadata refusal (pmtiles.rs:849), pool epoch growth (mbtiles.rs:351), raster-tile validation (mbtiles.rs:376), UI-thread validation (repair.rs:186), file:// alias invalidation (repair.rs:189), the pending view request (repair.rs:191), undo-depth assertion (reload_tiles.rs:129), the damaged first tile page test (reload_tiles.rs:170), and leaf-directory validation (pmtiles.rs:778). The plugins.rs:309 thread is addressed in this head by the READS_FILES change.
Change size
Compared: the whole PR against main (merge base 9ae69a3 to PR head 814df3d).
Approved round-1 review-body follow-ups at 96f1d6e:
The docstring-coverage warning and quality-only naming/refactoring/additional-test suggestions are left for the release quality pass; they are not repository compiler/test failures.
ci:full is applied. The new head's macOS, Windows and release checks are running; no unobserved platform result or atomic replacement of an open Windows archive is claimed.
The reason will be displayed to describe this comment to others. Learn more.
Extra global lock on every tile request (performance, low).request now takes the process-wide archive_epochs mutex before the cache lock, for every tile request, including cache hits. Answer::drop also takes it on every completed fetch. Tile lookups across threads therefore serialize on this one mutex, where before they serialized only on the cache lock. The lock is held briefly, so the cost is probably small, but a per-archive revision with an atomic read on the hot path would avoid the contention. Worth measuring on a large map with many tiles in flight.
Confidence: medium on the contention, low on whether it matters in practice.
The reason will be displayed to describe this comment to others. Learn more.
The shared revision lock prevents reload racing with publication of stale results; no measured contention regression is identified here. Profiling and any hot-path redesign are left for the release quality pass (reviewed at f766c1b).
Two inline comments were posted. A third, on pmtiles.rs:477, was rejected because that line is not part of the diff, so it appears below as a summary item.
Bugs
Low: A reload that drops a pending metadata read makes info_blocking return "no answer in N s" immediately, because the dropped callback disconnects the channel. The message blames the timeout, not the reload. Lives in crates/tiles/src/pmtiles.rs around line 477. Confidence about 55%; traced but not run.
Security
None found. map.reloadTiles carries Effect::Files, so touches_files covers untrusted tasks and notebooks. start_read runs authorize and check_read_command before admitting a background read. I checked the lock order in the epoch, cache, pmtiles, mbtiles and source paths and found no re-entrant or inverted lock. land, find and finish_leaf never drop callbacks while the epoch lock is held.
Performance
Low:request in crates/tiles/src/cache.rs:450 takes the global archive_epochs mutex before the cache lock on every tile request, and Answer::drop takes it on every completed fetch. Tile lookups now serialize on one mutex. Confidence medium on the contention, low on its practical cost.
Quality
Test coverage:crates/engine/src/tests.rs:3202 replaces the Slope error-message assertion with .is_err(). The PR doesn't explain this, and the change is unrelated to reload. Inline comment posted.
Docs vs code:docs/user-guide/maps.md says PMTiles validation does not check tile payloads. validate_directories still rejects any tile entry over 16 MiB as too large to read, which ordinary open accepts until that tile is drawn. Either document it or drop the check.
Error text:reload_tiles in crates/engine/src/cmd/repair.rs prefixes ({path}) to an error that already names the path, so the message repeats it.
AGENTS.md
The guidelines I checked are met: no new unwrap, expect, panic! or unsafe in non-test code; new user-visible UI text uses tl! or i18n::fmt; the wasm gating is in place; and the new reload and repair tests cover both lossy and clean inputs.
The engine's English notices and errors aren't translated. That follows the layering, since L4 can't reach i18n, so I did not flag it.
Already raised (left alone)

These include the MBTiles metadata row skipping, the PMTiles metadata and 16 MiB behaviour changes on the ordinary open path, the MBTiles alias invalidation, the undo-depth test, and the off-frame and plugin-trust points. Several of these are addressed by code in this PR, but their threads are still unresolved and no reply from the author yet answers them.

Review comments at @crates/engine/src/cmd/repair.rs:
- Around line 14-15: Update the map.reloadTiles command registration and its
reload_tiles flow to resolve and bind the selected tile and its private archive
path during approval, then use that same resolved selection when executing.
Include the path in the approval review only in the established redacted form,
preserving the existing selector and presentation behavior.
- Around line 207-210: Bind the prepared validation result to the archive
version used for drawing, not only to the map, settings, and path checked around
prepared.result. In the reload and repair flow, verify that the archive has not
changed since that version before reporting success or evicting retained tiles;
reject the operation if it has changed.
Review comments at @crates/engine/src/tests.rs:
- Line 3202: Update the `geolibre:slope` test so it first verifies that `Cities`
exists and is a vector layer using the test’s existing layer metadata mechanism,
then checks that `s.run` fails with the slope tool’s vector-input rejection
error rather than merely asserting any error.
Review comments at @crates/tiles/src/cache.rs:
- Around line 593-594: Bound the archive revision records stored in epochs so
closed projects and distinct reloaded paths do not accumulate indefinitely.
Update the reload completion tracking around the epochs entry and increment to
reclaim records only when no outstanding stale completion can still depend on
them, while preserving rejection of those stale completions.
Review comments at @crates/tiles/src/pmtiles.rs:
- Line 888: Check the installed cancellation probe before processing each entry
in the directory-validation loop over `dir`, and propagate cancellation through
the loop’s existing error path. Keep the check inside the loop so cancellation
stops further directory reads promptly.
- Around line 890-898: Update the directory validation path containing the
`e.run_length` check to reject tile runs that overlap previously accepted runs
before the candidate directory is accepted for reload. Preserve the existing
range and archive-bound checks, and ensure valid non-overlapping runs continue
through the current validation flow.
Review comments at @crates/ui-egui/src/lib.rs:
- Around line 2214-2222: Update the relay handling for map.reloadTiles so
archive validation runs through an authorized background read instead of
synchronously on the window thread. Preserve the existing authorization checks
and use the established background-read path around reads_off_frame and
readjob::run, ensuring relay reloads do not bypass RustGisApp::run’s required
validation behavior.

Round-2 review-body items (github-actions comment 6718805471) at f766c1b:
Timeout wording (pmtiles.rs metadata wait): a discarded callback can produce the existing timeout-style wording immediately, but the wait still returns an error and never publishes stale metadata. Distinguishing disconnection from timeout is left for the release quality pass.
Indexed-length documentation: validation checks the indexed stored length without reading tile payloads, consistent with lazy payload reads and the existing 16 MiB read limit. Explicitly documenting that check is left for the release quality pass.
Repeated path (repair.rs reload error): some underlying errors already name the path, so the wrapper can repeat it without losing the cause or retry guidance. Message deduplication is left for the release quality pass.
The reason will be displayed to describe this comment to others. Learn more.
Callback can be dropped unanswered (low-medium, ~60%).archive_epoch is read at line 491 and if_archive_current re-checks it here. If a reload lands between those two statements, the closure never runs, f is dropped, and nobody is told. info_blocking then sees Disconnected and reports "no answer in N s", which is misleading. Reloads run on the UI thread, but with_info is also reached from tile workers, so the window is real.
Suggested direction: keep f reachable and answer it with an error when the epoch is stale, for example let mut f = Some(f); and then if let Some(f) = f.take() { f(Err(crate::cache::DROPPED.into())) } in the None arm. Please add a test that forces the mismatch.
The reason will be displayed to describe this comment to others. Learn more.
The epoch race is real, but dropping the sender makes info_blocking fail immediately and tile Answer cleanup releases the fetch; obsolete callbacks are deliberately discarded on reload, so the remaining callback/error-reporting consistency work stays in the release quality pass. (reviewed at 8be9319)
The reason will be displayed to describe this comment to others. Learn more.
Reload refuses an archive that opens and draws (behaviour mismatch, low, ~50%). This check rejects any tile entry longer than MAX_BYTES, which fails the whole archive during validation. Ordinary open accepts the archive, and that one tile simply fails to read. The PR says validation checks directories and that tile payloads stay lazy, so this is stricter than the docs describe.
Either accept the entry here and let the tile reader report it, or document that an oversized tile refuses reload. Add a test whichever way you go.
The reason will be displayed to describe this comment to others. Learn more.
Ordinary open can draw other entries, but this oversized entry itself already fails the reader’s 16 MiB stored-read limit; we are retaining conservative indexed-length validation and the previously agreed release-quality-pass documentation item. (reviewed at 8be9319)
The reason will be displayed to describe this comment to others. Learn more.
Nit, never-crash rule.p["index"] = … uses IndexMut, which panics when p is not an object. The archive branch is only reached when find succeeded, so this is unlikely to trigger today, but AGENTS asks for no panic paths in non-test code. The let mut p = p; on line 112 also rebinds an already-mut parameter, so it is redundant and may trip clippy::redundant_locals.
The reason will be displayed to describe this comment to others. Learn more.
Fixed in 8be9319: archive selector normalization now uses checked object insertion instead of IndexMut, following the hostile-parameter rule; valid selectors and non-object rejection are covered. Removing the redundant let mut p = p is left for the release quality pass.
with_info silently drops its callback when the archive epoch changes between the two checks (crates/tiles/src/pmtiles.rs:492). info_blocking then reports a misleading "no answer in N s". Low-medium, ~60%. Inline comment posted.
Reload refuses an archive when any single tile entry exceeds MAX_BYTES (crates/tiles/src/pmtiles.rs:900). Ordinary open accepts it, so the behaviour differs from the docs. Low, ~50%. Inline comment posted.
readjob::stop (called from end_exports at exit) clears the waiting queue and the running job without not_run_asked. Relay-admitted reads never get finish_archive_read. Impact is small because the relay exits too. Low, ~50%. The line is unchanged context, so this is posted here rather than inline.
Security
No new issues. Approval binding, scope checks, revocation at landing, and the file-access effect on the new commands look sound from the code and tests.
Performance
placed() compares the full TileLayer on every frame while a read is queued or running, and archive_target clones it at admission. Low, ~30%. Not posted inline.
The global archive_epochs lock on every tile request was already raised in an earlier thread, so I left it alone.
Quality
readjob.rs:112-114: let mut p = p; rebinds an already-mut parameter, and p["index"] = … uses IndexMut, which panics on a non-object. Unlikely to trigger because find gates the branch, but it conflicts with the no-panic rule. Inline suggestion posted.
AGENTS.md
Never-crash: the IndexMut above is the only panic-shaped path I found in non-test code. Everything else checked uses get(), checked arithmetic, or budgets.
Never-silent: the new error paths report through notices or ToolResult. The one gap is the callback drop in the first finding.
Translation: new user-visible strings use tl!/tl_raw!/i18n::fmt. Engine error strings stay untranslated, as elsewhere.
Wasm: readjob is native-only, and the new archive helpers are cfg-gated. I did not build for wasm.
Already raised, left alone (7): the MBTiles row-skipping thread, the PMTiles metadata-strictness thread, the 16 MiB metadata thread (author answered), the undo-depth assertion, the weakened Slope: assertion (still present, no reply), the global epoch lock, and unbounded archive revision records. The other threads are resolved or fixed in this head.
Tests: I could not build or run anything. Findings come from reading the diff and the surrounding code.

- Around line 139-141: Normalize the command before the archive interception
check in the `run_command` matching logic. Trim the string obtained from `args`
before comparing it with `map.reloadTiles` and `map.repairTiles`, so
whitespace-padded permitted commands follow the read-worker path.
Review comments at @crates/assistant/src/relay.rs:
- Line 1014: Update the batch handling around `leave_agent` to persist each
successful layer selection before pausing for an archive reload, so
validation-time user selections cannot redirect later suffix operations;
preserve the existing pause and selection behavior otherwise.
Review comments at @crates/tiles/src/pmtiles.rs:
- Around line 892-895: Update directory validation around the run-overlap check

Review comments at @crates/data/src/mbtiles.rs:
- Line 818: Isolate the test containing the `connections.get(&other)` assertion
from the global pool so concurrent readers cannot evict its fixture. Use a
test-local pool for the test’s open and close operations, preserving the
assertion that the other path remains tracked after closing the target.
- Around line 467-473: Update the MBTiles metadata reload validation around the
metadata query so it checks metadata byte usage before converting values into
owned Strings with row.get. Reject metadata that exceeds the established byte
limit with an error, while preserving the existing 1,000-row limit and normal
metadata loading behavior.
Review comments at @crates/tiles/src/cache.rs:
- Around line 790-794: Update the archive invalidation and revision tracking
around `reload_archive` so absolute-path and `file://` aliases resolve to the
same archive identity. Use that shared identity to invalidate both aliases’
cached metadata and revisions, ensuring neither can pair replacement tile bytes
with stale offsets; preserve existing reload behavior for unrelated archives.
- Line 790: Update the lifecycle of the process-wide epochs map so paths no
longer used after project replacement are reclaimed. Preserve stale-completion
protection: reclaiming an entry must not let an in-flight operation for that
path pass the current-epoch check and publish; establish how epoch identity
remains distinct across removal and reinsertion.

information available from `render_pending`.
Review comments at @crates/ui-egui/src/mapgpu.rs:
- Line 1741: Add a test around `from_scene` that transfers a live archive scene
after a reload and verifies placement succeeds before a second reload but is

rather than supplying it directly, so it detects whether `from_scene` stores the
scene’s revision.

Review comments at @crates/engine/src/cmd/repair.rs:
- Around line 521-522: Update the archive validation path containing
pmtiles::read_info_local so cancelling a stalled PMTiles read releases the job’s
queue slot without waiting for the mounted-filesystem read to finish. Use an
approach compatible with the existing cancellation and queue ownership; preserve
validation behavior when not cancelled and ensure the detached read cannot cause
unsafe state changes after cancellation.
- Around line 595-597: Update the MBTiles sidecar observation around
FileRevision::read to check the WAL and journal beside the resolved database
target, not only beside the supplied path. Establish the resolved path before
observing sidecars and ensure their revisions are included before accepting the
candidate, preserving the existing validation flow.
Review comments at @crates/ui-egui/src/lib.rs:
- Around line 2240-2241: Update the archive repair flow around readjob::run so
the form stays open while background validation is pending; handle the landing
result before closing it, close only after successful validation, and preserve
the entered replacement path when validation fails so the user can retry.
Review comments at @crates/ui-egui/src/mapview.rs:
- Around line 4320-4326: Add a test that exercises the production adoption path
in main_view: complete a frame, reload the archive it depends on before
adoption, and verify main_view does not display that stale frame. Assert the
observable display result rather than reconstructing eligibility with a separate
condition such as the local eligible closure.
Review comments at @crates/ui-egui/src/readjob.rs:
- Line 123: Update the `called` value for the archive case so an empty archive
tile name uses an archive-specific fallback instead of producing a notice
labeled “Run Model.” Preserve non-empty archive names and ensure the leave
notice identifies the abandoned archive reload when the map or project changes.
- Around line 699-707: Extend the test containing the `run` calls to include a
second archive, then select that archive by name and ID. Assert that
`asked.archive` captures the nonzero archive index and that the operation lands
successfully, while preserving the existing index-zero assertions for the first
archive.
- Around line 704-708: Update the selector test around run and landed so each
name or ID request asserts its landing outcome, not just that the read started.
After landed, verify the completion result or a distinct refreshed archive
revision for each selector, using the existing result or revision state without
assuming a new API.
Review comments at @docs/user-guide/index.md:
- Line 239: Update the “Reloading a local tile archive” link in the user guide
to include a fragment targeting the reload instructions in the maps guide, and
add the corresponding anchor to the reload paragraph so the link opens at that
section.

I found no new defects in the code I traced, so there are no inline comments. The points below are either absent from the diff or already on an open thread.
Bugs: None new. Confidence: medium. This pass was partial (see coverage below).
Security: None new.
Performance: None new. The archive_epochs lock contention on every tile request is already raised (crates/tiles/src/cache.rs:574 thread).
Quality: None new worth raising. The layout preview's silently ignored Err (layoutview.rs) is already open.
AGENTS.md:
No violation found in the code I read.
The added production lines have no unwrap, expect or panic; the hits are all in test code.
New user-visible strings use tl! or i18n::fmt.
Not a breach: long_commands_stop_when_cancelled_while_they_run covers only the raster, export and tool lists, so the archive reads are outside it. The validators have their own cancellation tests (fresh_local_validation_cancels_before_reading_a_later_malformed_leaf, candidate_missing_zoom_scan_cancels_inside_sql_and_retries_cleanly).
Checked:
Lock order across archive_epochs, the tile cache, and the PMTiles and MBTiles state is consistent, and callbacks run after locks are released.
Relay pause and resume requeue requests in the right order, and every production poll caller pairs it with take_archive_read.
The PMTiles validator's section bounds, varint overflow, index budget, shared-range memo, depth and boundary checks.
The landing identity checks and the render revision guard.
archive_file() returns t.url verbatim, so the cache invalidation keys match the tile keys.
pmtiles::write's stricter metadata check: the production callers pass JSON objects.
Coverage limits: The diff is about 7,000 lines, most of it test code. I did not read the render layout, SVG and report internals, the tiles MBTiles module in full, or the mapgpu and tilt paths beyond the revision hunks. I did not build or run the tests.
Prior threads: The file holds 61 threads, 26 unresolved. I read roughly the first two-thirds and re-posted none of their concerns. I did not check the rest against this pass.

Compared: the whole PR against main (merge base f62c795 to PR head 0984fb1).
The reason will be displayed to describe this comment to others. Learn more.
Never hold the window: archive validation runs inline from notebooks and tasks (desktop, medium confidence, about 60%).
The background path is taken only when the desktop's RustGisApp::run is called directly with map.reloadTiles or map.repairTiles (crates/ui-egui/src/lib.rs), and for direct attached MCP run_command calls. notebook.run and task.run dispatch their children through Session::run in the engine, and reads::prepare only admits script.run, model.run and the layer.* reads. So a notebook cell or task step that reloads a large PMTiles index (up to 64 MiB) or scans an MBTiles file runs on the UI thread.
Two things would close this. Either route those children through the read queue, or state in this command's doc comment that it runs inline off the desktop's direct paths and why. AGENTS.md asks a command that must run on the UI thread to say why in its doc comment, and this one has none. The user guide also only mentions MCP run scripts, not notebooks or tasks.
The reason will be displayed to describe this comment to others. Learn more.
Fixed in 33e17dc: notebook cells and task steps run their children inline through Session::run on the window thread, like layer.addData and layer.reloadData; moving them all off-thread is a separate change to notebook and task execution. This PR now says so in both commands' doc comments (and why) and in maps.md/mcp.md.
I read the full 7,750-line diff, the staged AGENTS.md, and all prior review threads. Most concerns here have already been raised and answered in earlier rounds, so I left those alone. I found one new finding worth a line comment, plus a few minor quality points.
Bugs: None confirmed. I traced the cache's lock order (epochs → cache → queue/archives/leaves/infos/resolved) across request, Answer::drop, release, launch, reload_archive and the metadata and leaf paths. I found no re-entrant lock or deadlock. The relay's re-queue of paused requests keeps their order, and archive revisions are monotonic, so a reload always changes a captured revision.
Security: None found. Approval binding, the path boundary check and the scope checks held up on the paths I read. I did not find a bypass of the approval gate for archive commands.
Performance: The global archive-epoch mutex is taken on every tile request and every tile answer. Earlier threads raised this and it was deferred. I found nothing new.
Quality (minor, grouped; left for the release quality pass):
if_archive_current (crates/tiles/src/cache.rs) runs its closure while holding the global archive-epoch mutex. The archive_epochs doc says callbacks and I/O must run after the lock is released, and land, keep and remember_info run inside it. The current paths are safe, but the doc and the code disagree.
crates/ui-egui/src/repairsource.rs decides whether to show "Repaired {name}" by checking for started or waiting keys in the returned JSON. That is a fragile protocol between the command and the dialog.
AGENTS.md: Covered by the inline comment below. The stats for the other rules I checked (no unwrap on the new paths, the wasm gating, the hostile_params coverage, the writer's metadata-object check and its callers) look consistent. long_commands_stop_when_cancelled_while_they_run does not need the new archive reads: its lists cover only the raster, export and long-tool registries.
Inline comment posted:crates/engine/src/cmd/repair.rs:690 (medium confidence, about 60%). On the desktop, notebook cells and task steps that call map.reloadTiles or map.repairTiles run validation inline on the UI thread. The command has no doc comment saying why, and the user guide mentions only MCP run scripts.
Prior concerns left alone: about 40 threads were already raised. I did not repost them.
Change size
Compared with the base branch (merge base e46c27a to PR head 628d473).
I found no new confirmed bugs, security issues, or AGENTS.md violations in the parts I read. This is a sampled review of a 44-file, roughly 7,800-line diff. I read the cache epoch and locking, the MBTiles and PMTiles readers, the repair and reload validation, the MCP and relay batching, the desktop read queue, the policy gating, and the frame-adoption guard. I did not read the PMTiles directory-validation internals, the relay internals, the archive test files, or the render-layout code line by line. The other 62 existing review threads are unchanged, so I did not re-post any of them.
Bugs
None confirmed.
Low confidence (~30%, unverified against callers): in readjob.rsstart(), a spawn failure for map.reloadTiles/map.repairTiles calls session.notify and also returns Err. If the caller also reports the error, the user sees two notices for one failure.
Security
None found. Approval binds the selected tile and its private source. Both archive commands declare Effect::Files, and the engine tests cover that refusal. check_path runs before any archive metadata is observed.
Performance
Nothing new. The shared archive_epochs mutex on every tile completion is already raised.
Quality
Only the duplicate-notice point above.
AGENTS.md
Nothing new. The lock order I checked is consistent: archive_epochs → cache, archives, or pool, with no reverse path found. The documented PMTiles limits match the code: MAX_BYTES * 4 for 64 MiB, 1 << 20 entries, MAX_LEAVES * 16 for 4,096 directories, and MAX_DEPTH = 4.
Already raised and still open: notebook and task children validate archives inline on the UI thread (repair.rs). The new doc comments state the reason, but the "never hold the window" question for those callers is unresolved.
Change size
Compared with the base branch: the whole PR (merge base 8988b0f to PR head 0384c75).
Re the Claude review summary's low-confidence point (a worker spawn failure for map.reloadTiles/map.repairTiles notifying twice): checked the callers. The Layers row's menu ignores the returned error (let _ = app.run(..)), and the Repair form shows it in the form, so a failed worker start gives one notice (plus the form's inline message); the relay path answers the agent through not_run_asked. No change. (reviewed at 0384c75)

Summary
After another program updates a linked tile archive, RustGIS can keep drawing cached tiles and attribution. Add Reload Data to reread a local PMTiles or MBTiles archive without removing it or rebuilding its presentation.
map.reloadTilesaccepts the same name/index/catalog-id selectors as archive repair, without a replacement path. It preserves the archive's settings, style, order, visibility and map camera.This is manual archive reload only: no monitoring, notifications about detected changes, new dependency or serialized project field. Windows may still refuse replacement of an MBTiles file while SQLite holds it open; this does not promise atomic replacement of an open archive.
Ordinary archive loading is intentionally stricter too: malformed/non-object/truncated PMTiles metadata, a stored metadata section over 16 MiB, or unreadable/non-text MBTiles metadata is refused rather than silently losing credits or source-layer information. Repair/reload validates every reachable PMTiles directory within explicit limits: 64 MiB stored and 64 MiB decoded index bytes, 1,048,576 entries, 4,096 directories including root, four leaf levels and 16 MiB per stored directory. Exceeding a limit refuses without eviction; tile payloads remain lazy.

Unix coverage also replaces an open MBTiles inode.

ui_shotruns invoked each archive menu, failed against a temporarily missing path while retaining old tiles, then retried successfully after restoring changed archive bytes and attribution. Screenshots were inspected.Initial feature command-only wasm smoke executed the real command in Bun: registered, explicit local-file refusal, unchanged project and no undo step. Temporary source instrumentation was removed. The full browser-app smoke stalled; no browser UI success is claimed. Native OS behavior was exercised on macOS, not Windows.
Round-2 review fixes: archive approvals bind the selected tile and its private source (redacted in review); prepared reload/repair results are rejected if the file (or an MBTiles WAL/journal) observably changed after validation, before any eviction; PMTiles validation checks cancellation per directory entry and rejects overlapping tile runs; direct relay/MCP
run_commandreloads/repairs validate on the existing background read worker and reply only after landing (arbitraryrun/file-bridge scripts stay synchronous). Linked probes against the previous head reproduced each defect (stale approval accepted, stale result evicted retained pixels, overlap accepted, no cancellation checks, a 10.7 s blocked UI frame under an attached relay call); against the new head each flipped (relay frames ≤ 5.5 ms). Nativeui_shotsmokes covered a relay reload under an exclusive SQLite lock (Running/Cancel, error reply after landing with red tiles retained, green retry) and a held landing whose archive was overwritten after validation (rejected, red retained, green retry).Integration verification exposed an unchanged desktop startup-marker test failure once; the final default-parallel run passed. An unrelated GeoLibre 1.7.1 error-prefix assertion was removed with user approval while retaining the vector-input rejection and real raster/output/save/undo coverage.
ci:fullis applied for GitHub macOS/Windows/release coverage; local native UI smoke was macOS only.Round-3 review fixes: checked selector insertion, whitespace-normalized MCP archive interception, explicit-selection ownership before every archive pause, nested/memoized PMTiles run-boundary checks, and label-drag cleanup around resumed relay completion. Focused deterministic regressions and a fresh pre-push review passed. A new native
ui_shotsmoke inspected the integrated archive menu (including upstream Export Raster) and changed red tiles/credits to green/fresh credits at the same camera. Main integration includes upstream test(engine): the GeoTIFF tile-layer test no longer deletes an open archive (fixes main CI on Windows) #1618's Windows open-archive test fix; The full GitHub matrix at8be9319f, including Windows x64 and ARM64, subsequently passed; the latest push starts fresh checks.Round-4 review fixes: each archive pause binds project/map identity and rejects a changed-context suffix without dispatch; directory validation checks descendant lower bounds, including memoized references; the PMTiles writer explicitly rejects non-object metadata; docs distinguish background entry points from inline scripts. Native before/after runs reproduced wrong-map suffix mutation and malformed-index eviction, then verified explicit suffix rejection, retained red tiles on error, and green/fresh-credits manual retry after correction. Screenshots were inspected; focused regressions and the fresh six-file review passed.
Round-5 fixes and main integration: MBTiles metadata beyond 1,000 rows refuses instead of silently losing later credits; PMTiles writing enforces the reader’s 16 MiB serialized metadata limit; the native-only assertion is guarded. Main merge preserves destination-provenance checks and alternate reach outcomes alongside archive epochs. Fresh three-file and seven-overlap integration reviews approved; 408 tiles tests, 34 portable-project tests, the serialized full gate, pre-commit and normal wasm build passed. Native smoke reproduced the old attribution loss and verified refusal/retention plus corrected manual retry for both formats. An extra wasm tiles unit-test-target attempt was blocked by an unchanged native-only cache test from
53e06c699; it is not claimed passed.Initial feature review: two fresh approvals of the original 12-file change. Approved feedback fixes and main integrations received fresh reviews before pushing. The latest complete integration review found one PMTiles filename/cache mismatch; a failing-before/passing-after regression and native filename-boundary smoke verify the fix, and the follow-up reviewer approved it. The separate user-approved GeoLibre test-only correction also received a fresh approval.
UI evidence
PMTiles and MBTiles context menus and successful reloads below. The solid red/green tiles are synthetic fixtures; the lower-right credits change with the archive. Status bars were cropped out to exclude local filesystem paths.
PMTiles: menu before reload
PMTiles: changed tiles and attribution after retry
MBTiles: menu before reload

Background validation evidence
The actual native menu remained responsive with Running/Cancel while SQLite held an exclusive lock. Failure retained red tiles/credits; after unlocking, explicit retry displayed green tiles and fresh credits at the same view. The final native smoke also exercised PMTiles missing-file failure/retry with a
#cube=filename and explicitkind: pmtiles(URL kind guessing is separate).Related issue
Refs #1477. PR 2 of the three-part feature: manual archive reload only. Manual ordinary-layer reload and changed-on-disk detection/notifications remain separate; the tracking issue and roadmap item stay open.
