feat(mobile): bring the field's edits and photos back to the map they were packaged from (#1902) - #2029
Phase 3 of #1902: bringing edits back to the desktop project, with change tracking and conflict handling. Stacked on #2028 (the field package). Change tracking and conflict handling are the offline area's (Sync's), taken across devices: the area made when the map was packaged is the baseline, so features are compared three ways (as packaged, at home, in the field) by feature id.
Coming back (field::package): a field package's map (<area> (offline)) packages as it is, now with the photos its features name: each picture file on the device (.jpg, .png, .heic, .webp) goes in under photos/ with a plain name, and its feature names it there. A package going out to the field carries none. A photo named that isn't on the device (one named at home) is left as named; one that can't be read is said.
Phone: Send Field Package in the More sheet, shown with a field package's map open, saves it through Android's picker (ui.saveItem, kind fieldPackage).
Bring Back (offline.bringBack {"path"} or {"data"}; Data › Offline › Bring Back on the desktop, which picks the file): reads the package in the project it was made from. Its photos go in <area> photos beside the project (one whose name is taken there by other bytes gets a name of its own, said) (the app's own field photos/<area> for one not saved yet) and the features name them there. A field the phone appended to a layer (the photos field made with its first photo) is added to the layer at home and to the area's own copy, so the features aren't all taken as edited. Then sync_area (the body of offline.sync, now shared) copies the edits back by feature: changed and new features update the map (new ones get fresh ids), deleted ones are removed, and a feature changed at home too takes the field's version, said by name with Undo to restore the home versions. A summary says how many were changed, added and deleted, and where the photos went.
A package for an area this project doesn't have is refused, naming the area and saying to open the project it was made from.
Not in this pull request
Choosing per conflict which version wins: the field's does, as Sync's rule is, and the conflicts are named.
Fields that differ otherwise than by appended ones (a field removed or retyped on one side): refused by Sync, as before.
Bringing back off the window's thread: like Sync, it runs where it is called.
Testing
cargo test -p rustgis-engine --lib cmd::field (4 tests), the new one end to end in one process: a map packaged at home, opened as the field would, a city renamed, one added, one deleted and a photo attached (making a photos field); sent back with the photo under photos/; meanwhile the renamed city changed at home; Bring Back changed 1, added 1, deleted 1, said the conflict on Cities, put the photo in Trip photos beside the project with the feature naming it there; another project refuses the package by area name.
cargo test -p rustgis-engine --lib offline (Sync's own tests, on the shared sync_area), hostile_params_never_panic, cargo test -p rustgis-ui-touch, workspace clippy (-D warnings), cargo xtask layers, the wasm build and Android clippy pass. The full test suite was not run locally.
End to end across the CLI and the Android 15 emulator (x86_64): the CLI packaged the plots project with an MBTiles basemap and saved the home project; the phone opened the package, took a photo with its camera app and added Well C with it, and Send Field Package saved Site.rgisfield to Downloads through the picker (with photos/photo-20261114-025452.jpg in it); the CLI opened the home project and brought it back: "Added the field(s)…: Wells: photos", "…0 feature(s) changed, 1 added, 0 deleted; 1 photo(s) put in …/Site photos", and the saved home project's Wells holds Well C naming the photo there.
Not tested: the desktop app's file dialog for Bring Back (the ribbon button was rendered with ui_shot), the browser's, two phones sending packages of one area.
Field packages can now return offline edits and eligible photos to their source project. Importing a package applies feature additions, changes, and deletions, and reports conflicts.
The mobile app can capture photos and continue location tracking in the background when enabled.
Added field-package import and export options for supported offline maps.
Offline synchronization preserves new feature IDs when available and assigns new IDs when needed.
Bug Fixes
Field packages with mismatched areas or layer schemas are rejected, and failed package saves clean up temporary offline areas.
Photos are retained in the form if attaching them to a feature fails.
The changes add field-package photo handling, return synchronization, and interface actions for sending and bringing back packages. They also update mobile location-tracking state and photo handling.
Field packages include eligible photos when returning from a field package. The engine recognizes and rewrites photo paths according to the documented rules.
Returned edits and photos crates/engine/src/cmd/field.rs, crates/engine/src/cmd/workspace.rs, apps/rustgis-mobile/README.md
The return path checks package layers against the matching offline area, synchronizes feature edits, handles eligible fields and photos, and reports results. It retains feature IDs when available or assigns replacements when IDs are already used.
Package commands and interface crates/engine/src/cmd/workspace.rs, crates/ui-egui/src/lib.rs, crates/ui-egui/src/ribbon.rs, crates/ui-touch/src/lib.rs, apps/rustgis-mobile/README.md
The command registry and interfaces add field-package opening and sending actions. Project-item saves remove newly created offline areas after failed or cancelled saves. The README describes package creation and return behavior.
The Android activity retains requested tracking state and retries the tracking service on foreground return. The UI stores the out-of-sight tracking flag and retains more location fixes. The touch interface clears the flag after a successful switch to the desktop interface.
Photo request and form state crates/ui-egui/src/lib.rs, crates/ui-touch/src/lib.rs
The UI adds an optional camera callback and photo-path state. The touch interface retains photo paths in the form when attaching them to a picked feature fails.

Merge Risk: Moderate · up to b6dc4
Bringing field edits and photos back works in the common path, but several edge cases can overwrite photos or the open project file, hang the import, or stop background tracking. Fix the photo-destination collision, the metadata error loop and the native save guard before merging. The two-phone baseline limitation is documented but still open.

Explanation
The title names the main change: letting field edits and photos return to the map they were packaged from. It matches the changeset, which adds Bring Back, photo handling in field packages, and sync_area reuse. The title uses the conventional feat(mobile) prefix and includes a PR number. It is 96 characters, which is long, but the content is specific and accurate.
Full details: Description check
Explanation
The description follows the template sections: Summary, Testing, UI evidence, and Related issue. The Summary explains the change and its scope in detail. Testing lists the tests run, the end-to-end round trip, and what was not tested. The UI evidence section is absent from the template check, but the template says to keep the 'No visible UI change.' line. The author kept that line, but the change adds a visible Bring Back ribbon control and a Send Field Package button in the More sheet, so that line is inaccurate. The author's comments mention screenshots, but the description does not attach them. The Related issue section says 'Part of #1902.' This is adequate. The main gap is the UI evidence section. The template requires before and after screenshots for visible UI changes, and the description states no visible UI change while the PR adds new UI controls.
Resolution
Replace 'No visible UI change.' in the UI evidence section. Attach after-only screenshots of the new Bring Back control in the Data > Offline ribbon group and the Send Field Package item in the phone More sheet. Attach the Android save picker screenshot if relevant. The PR comments reference screenshots, so move them into the description.

A rabbit packs the field-map tight, With photos tucked away from sight. It hops back home with edits new, And finds the paths that still ring true. Then nibbles clover, pleased and bright.
The round trip, across the CLI (as the desktop) and the Android 15 emulator (x86_64).
New on the desktop: Data › Offline › Bring Back, beside Sync (light theme, ui_shot).
On the phone, with the field package open after Well C was added with a photo: left, Send Field Package in the More sheet; middle, Android's save picker offering Site.rgisfield. Right: back home after Bring Back, the map exported by the CLI with Well C inside the plot, beside the photo the phone's camera took, now in Site photos beside the home project.
I read the full diff, the base-branch AGENTS.md, the surrounding engine code (Session::run rollback, sync_area, zip and file readers, the desktop and Android open paths) and the touch sheet's row count. No prior review threads exist on this PR, so none were left alone. Build and tests were not run here (no shell); the findings below come from reading the code.
Bugs
Photos overwrite each other on bring-back (field.rs ~266, medium-high): bring_back writes into <area> photos with std::fs::write and replaces any existing file of the same name without a notice. Phone camera names collide across devices or packages, so one photo can silently replace another.
Photo entries dropped without a notice (field.rs ~233, medium): names starting with . or containing : are skipped silently, and the feature keeps a relative photos/<name> path that doesn't exist at home.
Refused sync leaves side effects (low): take_new_fields notifies "Added the field(s)…" and bring_back writes photo files before sync_area can refuse. Session::run restores the project on error, but not the photo files, and I did not confirm whether the notice survives the rollback.
Security
Photo paths read from the project (field.rs ~183, low-medium, design question): any absolute path named in a photos field is read and embedded in the package. The same check also covers fresh desktop packages, since the map is renamed (offline) before it runs. Tile archives already follow this pattern.
Performance
None found. rewrite_photos and the field loops are linear.
Quality
The " (offline)" literal is repeated in ui-touch (twice) and in field.rs. The const OFFLINE is pub(crate) and not reachable from ui-touch.
The command is labelled "Bring Back Edits" in the registry, but the ribbon and README say "Bring Back".
Test gaps: no test for a photo-name collision, a skipped hidden name, or the notice for a photo not on the device.
These are for the release quality pass, not this PR.
AGENTS.md
Never hold the window (field.rs ~216, high): offline.bringBack does unbounded file and sync work on the UI thread, and its doc comment doesn't say why it must. The PR description concedes this but the doc comment must carry the reason.

Four inline comments are posted. Each names its file and line, gives a confidence, and includes a suggested fix where one is small.
Photos don't survive a round trip; the phone's send-back drops them and features are rewritten to dead relative paths. A home package names photos photos/<name>. On the phone, take_photos skips non-absolute paths, so the returned package omits them. Bring Back then leaves photos/<name> in the home features with nothing written and no notice. Separately, a fresh desktop package is also treated as returning (returning_map matches <area> (offline)), so take_photos rewrites every photo path and bring-back counts each such feature as changed, and can report false conflicts. The round-trip test uses only a phone-taken absolute photo, so it misses this. Confidence: high (~0.75). Inline comment posted at crates/engine/src/cmd/field.rs:205.
A photo with : in its file name makes the whole package refuse to open on the phone.take_photos keeps the name, and unpack_into (field.rs:383) rejects any path part containing :. Confidence: medium (~0.5). Inline comment with a suggestion posted at field.rs:124.
Security
No new issues. The photo-path read and the embedding of arbitrary readable files are already raised in the prior threads.
Performance
No significant issues. take_photos is bounded by the shared budget, and the per-feature rewrite is linear.
Quality
Nit, left for the release quality pass: the " (offline)" literal is repeated in ui-touch, workspace.rs and field.rs instead of using field::OFFLINE.
bring_back writes photos to disk before sync_area can refuse the sync, and Session::run rolls back the project but not those files. A failed run leaves orphaned photos beside the project. Confidence: medium (~0.6).
AGENTS.md
Visible UI changes (the Bring Back ribbon button and the touch "Send Field Package" row) ship without screenshots in the PR body. AGENTS.md asks for before/after or after screenshots for visible changes. Confidence: high (~0.8).
The round-trip gap above is also a "never silent" breach: rewrite_photos leaves unresolved photo names without a notice.
Four earlier concerns were left alone because they were already raised and not answered: no UI-thread reason in the bring_back doc comment, silent overwrite of same-named photos, silent skip of dotted or colon names, and embedding any readable file a photos field names.
Change size
Compared with feat/mobile-field-package (merge base 2c84bc8 to PR head 8b07dd4).
- A photos field of that name that isn't text says nothing was added or attached, instead of reading as if the feature went in without its photos.
- Only the photos a field doesn't list already are counted in the notices, and attaching none new makes no edit; tested.
- A photos field made for a feature that is then refused is taken away again, and said, so a refused add leaves the layer's design as it was; tested.
- A held list ending in `;` gets no empty entry before the new photo; tested.
Second Bring Back duplicates features the field added earlier. Each round a field-added feature gets a fresh home id, but the phone keeps its own id. The next package's id is not in the area's baseline, so the feature is added again on every round. Not run; confidence medium-high. Anchored at field.rs:477, cause at workspace.rs:754-776, which is outside the diff. No test brings back twice.
A photo whose metadata can't be read is dropped without a notice.Path::is_file() returns false on any error, so the path is left as named and not counted. Confidence low-medium (~0.4). field.rs:294.
Already raised and still open (not re-posted): the unbounded std::fs::read on index paths (field.rs:448), overwriting a photo that can't be read (:459), files left behind when sync refuses (:477), the O(n²) stat loop in photo_paths (:257), and photos packed for an offline map opened on the desktop, which contradicts the README (:63, no answer yet).
Security
None new. Photos are restricted to picture extensions and plain names, and the package is size-bounded by read_file and zip::read.
Performance
Low: each candidate name in the photo loop is read in full just to compare bytes. Compare lengths first. Posted with the nits at field.rs:467.
Quality
The README lists four picture types, but the code accepts six (.jpeg and .heif are missing). High confidence. Posted with a suggestion at apps/rustgis-mobile/README.md:190.
Nits (grouped at field.rs:467): identical bytes already in place are rewritten and counted as "put"; Undo leaves the copied photos on disk; a newline in a photo path breaks the index.
AGENTS.md
The PR body has no screenshot or link for the visible changes (the ribbon button and the touch "Send Field Package" row). AGENTS requires them.
The bring_back doc comment's UI-thread reason is present, so that rule is met.
Already raised, left alone: 5 open threads and 13 resolved threads, which I checked and did not re-raise.
Inline comments posted: 4 (field.rs:294, field.rs:467, field.rs:477, README.md:190). One comment was first attempted on workspace.rs:776, which is outside the diff, so it was moved to field.rs:477.
Change size
Compared with feat/mobile-field-package (merge base 92c2304 to PR head c76ed01). Sizes are file sizes; trees were not truncated.
- The browser refuses a field package by name, saying to open it on a computer or a phone (its basemaps are files a page has no folder for), and that Bring Back takes its edits there.
- The packaged map goes as it is: rasters are taken out before, so embedding them did nothing; `embedded_map` is private again.
- What stays in the project (tables, notebooks, models, layouts, other maps…) is said, by count; tested both ways.
- A basemap archive's name keeps only letters, digits, `-`, `_`, `.` and spaces, so every system can unpack it; tested with `*?` in the name.
- `offline.package` refuses the open project's own file as its path; tested.
- A field package made from an extent (the view, unless one is given) says how many features stayed out of it, outside the extent or without a shape; tested both ways.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Move field-package generation off the desktop interface thread.
For a map with a large local PMTiles or MBTiles archive, this call reaches field::package. That function reads the archives and writes the ZIP synchronously. The window cannot process input or cancellation until packaging finishes. Move generation to background work and apply session changes when it completes. (raw.githubusercontent.com)
As per coding guidelines, “On the desktop, long work never holds the window.”

- Line 145: Update the tracking failure handling around the self.keeping
assignment to distinguish Android background-tracking refusal from a generic
failure. On refusal, synchronize self.keeping and app.keep_locating with Java’s
keepLocating=false state, and provide a way to retry starting TrackService for
the active recording without ending it; preserve the existing handling for
unrelated failures.
Review comments at @crates/engine/src/cmd/field.rs:
- Line 477: Update the Bring Back flow around sync_area to use the baseline and
exchange identity carried with each package, rather than the latest imported
area.data snapshot. Ensure each package is merged against its own baseline so
importing another package cannot revert prior edits or delete added features.
- Line 424: Update the area-package validation around the `offline_areas` lookup
so a matching area name alone cannot authorize restoration. Persist a stable
project-and-area identity in the package and validate it before restoring photos
or applying edits in `sync_area`; establish and reuse the appropriate identity
symbols without relying on numeric layer or feature IDs.
- Line 351: Update the FORBIDDEN set used by plain_name to include semicolons,
so sanitized packaged photo filenames cannot contain the delimiter that
photo_paths splits on.
Review comments at @crates/ui-egui/src/lib.rs:
- Line 4037: Check the boolean result of self.download in the
download-submission branch and call forget_new_areas when submission fails,
matching the rollback behavior of the native write-failure branch; retain the
offline area only when the download is successfully submitted.
Review comments at @crates/ui-egui/src/ribbon.rs:
- Line 1001: Update the fieldPackage save flow that calls item_bytes to compare
the project’s offline_areas count before and after the save; call mark_unsaved
only when a save successfully adds an area. Preserve forget_new_areas behavior
so cancelled or failed saves that restore the count leave the project clean.
Review comments at @crates/ui-touch/src/lib.rs:
- Line 931: Update the photo-attachment failure branch around photos::attach so
the paths in taken remain available through the form or a retryable attachment
request when attachment fails. Preserve them until attachment succeeds or the
user removes them, rather than dropping them after the notice.
- Around line 89-91: When the “Use the Desktop Interface” action removes touch
chrome, also reset app.keep_locating in that same branch so TrackService does
not remain active; preserve the existing stop_track and notification behavior.

- A photo path from a package's index is compared by its size first and never read past it, so a device or pipe named there can't hold the window.
- A file already where a photo would go is kept unless it is the same photo (same size and bytes); anything else, or one that can't be looked at, gets a name of its own.
- Where each photo goes is decided before the edits are brought back, and the photos are written after: a refused sync leaves no photo or folder, and a failed write takes those written before it away again.
- A path with a `;` of its own is tried only from an absolute start and over at most 16 pieces.
- Only a map opened from a field package carries its photos: an area's map going out from here carries none.
- A photo on this device that can't be looked at is said, as one that can't be read is.
- The README lists every picture kind, says one package goes to one phone at a time, and that a package whose layers aren't the area's is refused.
- A feature added offline keeps its id when the source doesn't use it, so the next Bring Back of the same phone's copy finds it as itself; one that takes a new id is said; tested both ways.
- A package from an area of the same name in another project is refused: its layers, by id, must be the area's, of the same kind; tested.
- `;` is never in a packaged photo's name.
- The activity remembers that a track wants positions out of sight, and tries TrackService again when the app comes into sight after it was refused.
- A failed handover of a field package (the download hook) forgets the offline area made for it; one kept marks the project unsaved, so Bring Back can find it after the project is saved.
- Switching to the desktop interface stops keeping positions out of sight.
- Photos that couldn't be attached to the feature being edited stay in the form.

Bug (hang on the window's thread), high confidence from reading the code, not run. The loop only stops on NotFound or on a matching file. Any other metadata error (NotADirectory when a component of dir is a file, such as a file named <area> photos beside the project; PermissionDenied on an unsearchable folder) falls into _ => and moves to n-<name>. Every candidate fails the same way, so for n in 2.. never ends, and Bring Back freezes the app with no Cancel. The round-trip tests don't cover it.
Fix: return the error for anything but NotFound. Nothing has been written at this point, and the edits haven't been applied either, so the command can fail cleanly:
Suggested change
_ => path = dir.join(format!("{n}-{name}")),
Err(e) => returnErr(format!("{}: {e}; no photo was brought back", path.display())),
Ok(_) => path = dir.join(format!("{n}-{name}")),
A regression test should create a plain file where <area> photos should be and assert that the command returns an error without hanging.
The reason will be displayed to describe this comment to others. Learn more.
Re-raising the open origin concern (new evidence, same risk). The area is still matched by name, and the new check only compares layer ids and geometry kinds. That is not a project identity: layer ids come from a per-map counter that starts at 1 (next_layer_id: 1, crates/map/src/lib.rs near line 1611). Two projects built from the same template or sample have layers with the same ids and kinds, so a package from a different project's area named the same passes. sync_area then matches features by id, so the other project's features are overwritten, deleted or added to the wrong area, and the summary only reports counts. The renamed test passes only because its layer geometry differs by coincidence.
Fix: store a persistent project/area identity in the package (for example a random id set when the area is made, saved in the project and in the package) and refuse a package whose identity differs. Matching names and layer ids should not be enough.
Bring Back can hang the window forever. The name search in bring_back (field.rs:531-538) only stops on NotFound or a matching file. Any other metadata error (e.g. NotADirectory when a file sits where <area> photos should be, or PermissionDenied) falls through to _ => and retries with the next name, so the loop never ends. Inline comment posted with a fix. Confidence: high (code-read, not run).
Origin check still doesn't identify the project (re-raised). The area is matched by name, and the new check only compares layer ids and geometry kinds. Layer ids come from a per-map counter starting at 1, so two projects built from the same template can pass, and sync_area then overwrites or deletes features by id in the wrong project. Inline comment posted. Confidence: medium-high. This is the open CodeRabbit thread; the code changed, but the problem remains.
Security
No new issues. Photo entries are restricted to plain names, and the index/holds() paths are size-bounded. Photos from a package are only compared, never written to a hostile path.
Performance
Packages going back carry the whole offline basemap (up to half the budget), which Bring Back never uses. Confidence: medium. Consider leaving tile archives out when coming back.
Quality
A directory named in a photos field is left silently (take_photos, the Ok(_) => return path arm). Confidence: low.
crates/ui-touch/src/lib.rs repeats the literal " (offline)" where field::OFFLINE exists. Confidence: high, minor.
Left for the release quality pass, as the review guidelines allow: none.
AGENTS.md
The PR adds visible UI (the Bring Back ribbon button, the More-sheet row, the touch changes), but the body has no screenshots. The description says the ribbon button was rendered with ui_shot but doesn't attach it. AGENTS.md requires before/after or after-only screenshots. Confidence: high.
Desktop Sync now keeps a feature's offline id when it's free, and renumbers silently when it isn't. The "renumbered" notice is only in Bring Back. Confidence: low.
Already raised (left alone): the reply-thread concerns about the second-phone baseline, the photo-write ordering, the ;-path handling, the picture-type notice, the area-name and origin check (re-raised above), the unlisted photo write-order, and the nits about index newlines. Eight earlier threads were resolved or addressed in the pushed commits, and I checked those fixes against the code.

The native ui.saveItem branch writes to whatever path the save dialog returns and skips that check. A user who selects the open .rgis project in the dialog replaces the project with package bytes. A user who selects the opened .rgisfield replaces that input package.
Run the same check before the write, and only for field package saves. Other item kinds must keep their current save behavior. If the check fails, remove the areas made for the package:
Suggested fix
match dialogs::pick_save(&name, &[ext], tl!(label)) {
Some(path) => {
+ if kind == "fieldPackage" {+ if let Err(e) = rustgis_engine::cmd::field::not_the_project(&self.session, std::path::Path::new(&path)) {+ rustgis_engine::cmd::field::forget_new_areas(&mut self.session, areas);+ return Err(e);+ }+ }
if let Err(e) = rustgis_engine::data::io::write_atomic(std::path::Path::new(&path), &bytes) {
The UI crate must also call the function, so its visibility must change in the engine crate:

Notify the field-package rejection where it occurs.
When a browser picker or drop sends a .rgisfield file through the inbox, the branch returns its explanation without calling session.notify. The inbox loop discards that result, so the user sees no reason the package did not open.
Notify at the rejection site, not in the inbox loop. The shapefile branches in open_picked already notify before returning Err. A loop-level notification would report those errors twice. open_project_bytes rejects the same file separately, so this change leaves that path unchanged.
Suggested fix
if lower.ends_with(".rgisfield") {
- return Err(tl!("A field package opens on a computer or a phone, which have a folder for its basemaps: open it there. Bring Back (Data › Offline) takes its edits into the project here.").to_string());+ let error = tl!("A field package opens on a computer or a phone, which have a folder for its basemaps: open it there. Bring Back (Data › Offline) takes its edits into the project here.").to_string();+ self.session.notify(error.clone(), true);+ return Err(error);

- Around line 282-284: Update the retry condition around keepWanted and
keepLocating in MainActivity so startTrackService() runs only when locating is
still true after location startup. Preserve the existing keepWanted and
keepLocating checks.
- Around line 282-284: Update the retry flow around onStart and
startTrackService so a pending refusal from serviceRefused cannot clear
keepLocating after a later retry succeeds. Ensure takeEvents can still process
the refusal without invalidating the successful retry state.
Review comments at @crates/engine/src/cmd/field.rs:
- Line 544: Update the planning loop around `placed.insert` so each selected
photo destination is reserved before planning the next photo. Include reserved
destinations in collision detection alongside files already on disk, ensuring
different package photos cannot select the same path.
- Line 572: Update the Bring Back import flow around the photo directory lookup
and the create_dir_all/write operation so browser imports never fail on
filesystem access after applying edits. Before applying any edits, either use an
established browser-compatible photo store or reject packages containing photos
with a message directing users to import them on desktop or phone; do not rely
on the existing “save the project first” message.
- Line 538: Update the candidate metadata match in the `bring_back` search so
only `NotFound` starts a new candidate and an existing path with different
contents advances to the next number. Return other metadata errors immediately,
preserving the error for the caller instead of treating them as collisions.

Replace 'No visible UI change.' in the UI evidence section. Attach after-only
screenshots of the new Bring Back control in the Data > Offline ribbon group and
the Send Field Package item in the phone More sheet. Attach the Android save
picker screenshot if relevant. The PR comments reference screenshots, so move
them into the description.

Summary
Phase 3 of #1902: bringing edits back to the desktop project, with change tracking and conflict handling. Stacked on #2028 (the field package). Change tracking and conflict handling are the offline area's (Sync's), taken across devices: the area made when the map was packaged is the baseline, so features are compared three ways (as packaged, at home, in the field) by feature id.
field::package): a field package's map (<area> (offline)) packages as it is, now with the photos its features name: each picture file on the device (.jpg,.png,.heic,.webp) goes in underphotos/with a plain name, and its feature names it there. A package going out to the field carries none. A photo named that isn't on the device (one named at home) is left as named; one that can't be read is said.ui.saveItem, kindfieldPackage).offline.bringBack {"path"}or{"data"}; Data › Offline › Bring Back on the desktop, which picks the file): reads the package in the project it was made from. Its photos go in<area> photosbeside the project (one whose name is taken there by other bytes gets a name of its own, said) (the app's ownfield photos/<area>for one not saved yet) and the features name them there. A field the phone appended to a layer (the photos field made with its first photo) is added to the layer at home and to the area's own copy, so the features aren't all taken as edited. Thensync_area(the body ofoffline.sync, now shared) copies the edits back by feature: changed and new features update the map (new ones get fresh ids), deleted ones are removed, and a feature changed at home too takes the field's version, said by name with Undo to restore the home versions. A summary says how many were changed, added and deleted, and where the photos went.Not in this pull request
