fix(engine): update typed references when a layer is renamed - #1718
Renaming a layer leaves typed references in layouts, reports, models and editing settings pointing at its old name. Carry those references with the renamed layer, including map series, relationships, topology rules, elevation surfaces and imagery workspaces.
Map-local references follow only their map. Project-wide references stay unchanged when another map has the old or new name. A destination-name collision also keeps affected references unchanged, with a counted notice explaining how to choose the intended layer. Script text, history and untyped tool parameters are left intact. Undo restores the layer name and its references together.
Testing
Passed cargo xtask ci (5,365 passed, 0 failed, 22 ignored), the rustgis-web WebAssembly build and all pre-commit hooks on 9e03e84d.
Five focused regressions cover the typed reference categories and undo, references in two maps, and destination-name collisions within and across maps, and counted references retained on a duplicate old name, including layer masks. The mask regression checks that the combined count is two and Undo restores the complete project state. Rendered and inspected the actual ambiguity notice with ui_shot.

Summary by CodeRabbit
New Features
Renaming a layer updates matching references in the active map, including masks, relationships, topology rules, elevation settings, layouts, charts, colorbars, and map series, when the rename is unambiguous.
Matching project-wide references in reports, models, and workspaces are updated when other maps do not create ambiguity.
Bug Fixes
Ambiguous references are left unchanged, with a notice when applicable.
Undo restores the project state from before the rename.
Layer renames now update eligible typed references in maps, layouts, and project-wide objects. References remain unchanged in specified ambiguous-name or cross-map cases, which produce notices. Tests cover these conditions and verify that undo restores prior project state.

Merge Risk: Low · up to 9e03e
After a case-only layer rename, the elevation or Map Series selector may show no selected layer even though the reference still works. This is a bounded UI issue that can be fixed before merge or accepted for follow-up.

A layer shifts its name one day, Its typed references find the way. When names collide, they pause instead, A notice marks the path ahead. Two undos bring the old state back, The rabbit hops along the track.
The reason will be displayed to describe this comment to others. Learn more.
Bug (confidence ~70%): a project-wide reference can be redirected to another map's layer.report.rsfind_layer checks the active map first, then falls back to any map in project order. Suppose map A is active with layer Countries, and map B has a layer Nations but no Countries. A report on Countries is not shared (no other map has Countries), so project_reference renames it to Nations. When B becomes active, the report now silently shows B's Nations. Before the rename it always resolved to A's Countries. The shared check guards the old name but not the new one, and the collision check only looks at the active map.
Fix: also keep project-wide references when another map already has a layer named new, and add that case to the notice. Add a regression test with a second map that holds the new name, and check that the report keeps Countries and that the notice fires.

Fixed in 6041f09. Project-wide references now stay unchanged when another map has either the old name or the destination name, with a counted notice. The regression covers the destination-name collision and undo. Five focused regressions, full native CI, WebAssembly and hooks passed.

Two related issues on this early return.
Case-only renames never update references (confidence ~40%, cosmetic).eq_ignore_ascii_case matches the renamed layer itself, so renaming Countries to countries returns here. References keep the old spelling. They still resolve because layer_by_name is case-insensitive. Excluding the renamed layer (its name now equals new exactly) fixes this:
Suggested change
if s.map().layers.iter().any(|l| l.name.eq_ignore_ascii_case(old)){
if s.map().layers.iter().any(|l| l.name.eq_ignore_ascii_case(old) && l.name != new){
Silent skip (confidence ~50%). When another layer in the same map still has old, nothing is updated and no notice is given. The references quietly keep pointing at that other layer. The terrain path in rename gives a notice for the same ambiguity, and the collision path here does too. Consider a counted notice for this case, since AGENTS.md says "never silent".
The reason will be displayed to describe this comment to others. Learn more.
The duplicate-old-name case is fixed in 6041f09: retained references are counted and the notice explains that another layer in the active map still has that name. The regression checks both the retained table reference and its notice.
Case-only spelling changes still resolve through the case-insensitive lookup. Updating that cosmetic spelling is left for the release quality pass.
The reason will be displayed to describe this comment to others. Learn more.
Nit (AGENTS.md "Test both ways", confidence ~60%): this test only checks that references follow the rename. It never checks that a clean rename gives no notice. Capture let mark = s.notice_mark(); before the Countries rename, then after the dem rename add assert!(s.notices_since(mark).is_empty(), "a rename that breaks no name gives no notice");.
The reason will be displayed to describe this comment to others. Learn more.
The extra clean-rename notice assertion is left for the release quality pass. The existing positive regression checks reference updates and undo; ambiguity notices are emitted only for counted references kept unchanged.
A project-wide reference (report, model input, imagery image) can be silently redirected to another map's layer that already has the new name. find_layer falls back to other maps, so the report starts showing that layer when that map is active. The shared check guards only the old name. Confidence ~70%. Inline comment on crates/engine/src/cmd/layer.rs:4793.
Case-only renames (Countries → countries) trip the early return because the renamed layer matches its own old name. References keep the old spelling. They still resolve, since layer_by_name is case-insensitive. Confidence ~40%, cosmetic. Suggestion block on layer.rs:4724.
Security
None found. The new code takes only layer names, which are treated as literal data through NoticeText::format.
Performance
None found. The work is a few linear passes over the project and runs once per rename.
Quality
Nit: references_follow_layer re-implements named_layers inline (layer.rs:4731) and repeats the replace closure pattern. This can wait for the release quality pass.
AGENTS.md
Silent skip: when another layer in the same map still has the old name, nothing is updated and no notice is given. Unlike the terrain path and the collision path, this one is silent. Confidence ~50%. Same layer.rs:4724 comment.
Test both ways: what_names_a_layer_follows_its_rename checks that references follow the rename, but not that a clean rename gives no notice. Confidence ~60%. Inline comment on tests.rs:24888.
I found no crash paths. The new code has no unwrap, expect, or indexing outside tests, and the notices are counted, one per kind. I checked all the typed reference kinds the diff claims to cover against layout.rs (Table, Chart, Colorbar, map series) and design.rs (Relationship, TopologyRule, Elevation). Legend exclude is handled by the existing legends_follow_layer. Layer masks and terrain are handled by the existing rename code. The tile rename path in tiles.rs doesn't need the new helper, because tile layers aren't typed references.

- Around line 24913-24922: Narrow the stale-name assertion built from `refs` so
it checks only actual layer-reference fields, rather than every string collected
by `strings`; preserve coverage for model input, relationship, and imagery
workspace references. Keep display text and user-provided names out of this
check.
- Around line 24928-24961: Update `layer_rename_keeps_references_in_their_maps`
to assert that the first map’s layer is renamed to `Nations` while the second
map retains `Countries`. Also verify which map each layout’s frame displays
before relying on the positional `zip`, so the layout-reference assertions are
tied to the intended maps.

Fixed the cross-map destination-name collision and the missing duplicate-old-name notice in 6041f09. Both new regressions and the original three passed; full native CI passed 5,365 tests, with WebAssembly and hooks also passing. The updated ambiguity notice was rendered and inspected.
The cosmetic case-only spelling change and extra clean-rename assertion are left for the release quality pass.

Layer masks ignore the ambiguity rule this PR adds (confidence ~60%). The mask loop just above (lines 97-101, not in the diff, so pre-existing) renames every mask equal to old to new without checking whether another layer still bears old, or whether new now collides. references_follow_layer applies exactly that check to every other map-local reference (its doc: "A name still present there keeps its references"), so the mask is the one map-local reference left out of the policy.
Failure scenario: a map has Countries (A) and a second layer Countries (B), and Cities is masked by Countries. Renaming A to Nations silently moves the mask to A. Before the rename the mask was ambiguous, so the PR's rule says keep it and count the notice.
Suggested fix: remove the mask loop from rename and handle masks inside references_follow_layer with the same replace closure, e.g. for layer in &mut s.map_mut().layers { if let Some(mask) = layer.mask.as_mut() { replace(mask); } }. A test with a duplicate old name and a masked layer would cover it.
The reason will be displayed to describe this comment to others. Learn more.
Fixed in 9e03e84. Layer masks now use the same ambiguity checks and counted notices as the other references. Duplicate old names and destination collisions keep the mask unchanged; case-only renames preserve the existing spelling update.
The duplicate-name regression checks the retained mask, combined count of two and complete Undo restoration. All five focused tests passed, followed by full CI (5,365 tests), WebAssembly and hooks. The actual UI notice was rendered and inspected.
Layer masks skip the ambiguity rule (layer.rs:97-101, pre-existing, posted inline at line 104). The mask loop in rename redirects every mask named old to new even while another layer still bears old, so a mask can silently move to the wrong layer. Confidence ~60%.
Stale references can start resolving (low, ~30%). A report or relationship that already names new (dangling, after its layer was removed) now binds to the renamed layer. The notices don't mention it. Not posted inline.
Case-only renames keep the old spelling (layer.rs:4725, cosmetic, ~40%). old_present matches the renamed layer itself, so the early return fires. Names still resolve case-insensitively. This was raised in an earlier thread, and the line has changed, but the behaviour is the same. Left alone as a quality point.
Security
None found. Layer names reach notices only as literal arguments through NoticeText::format, and redacted() is applied.
Performance
None. The new function makes a few linear passes over layers, layouts and project items.
Quality
The "choose the intended layer in those items" notice gives no way to do that from the UI. The count also says "layer reference(s)" when the duplicate is in the active map, even for project-wide items.
references_follow_layer is about 120 lines with three closures. A split into per-category helpers would help readability.
AGENTS.md
No unwrap, expect or panic in the new non-test code. Every ambiguous case gives a counted notice. Undo is tested.
Checked the rename path: UI, CLI, assistant, plugin and script calls all go through layer.rename, so the hook isn't bypassed.
Missing negative test: a clean rename should give no notice ("Test both ways"). Already raised in an earlier thread; the author deferred it to the release quality pass. Left alone.
Already raised, left alone: 4 earlier threads.
Project-wide redirect to a new-name layer in another map: the shared check now covers the new name too, and the regression test exercises it. Answered by the code.
Missing clean-rename notice assertion: deferred by the author.
Over-broad stale-name check in what_names_a_layer_follows_its_rename: deferred by the author.
Extra fixture assertions in the two-map test: deferred by the author.
Confidence on the overall correctness of the core logic is good. I traced the active-map, shared, collision and duplicate paths and they produce the intended results.
Change size
Compared: the whole PR against main (merge base 46c86be to PR head 6041f09).
The mask ambiguity bug is fixed in 9e03e84: masks now share the same retention/counting policy as the other typed references. Five focused tests, full native CI (5,365 tests), WebAssembly and hooks passed; the inspected screenshot is in the PR description.
An existing dangling reference to the destination name resolves when a layer acquires that name, as it does when a matching layer is added. Distinguishing that reference's former identity would require an identity-model change beyond this by-name reference repair. Case-only spelling, notice wording and the helper split remain for the release quality pass.
The reason will be displayed to describe this comment to others. Learn more.
Bug (confidence ~65%): references that already name the destination are silently redirected.layer_by_name (crates/map/src/lib.rs:2541) returns the first case-insensitive match. The collision branch only counts references to old, so a reference that already named new is never counted or noticed.
Failure scenario: layers [Parcels, Cities (mask = "Countries"), Countries]. Renaming Parcels to Countries makes the first match the renamed layer. Cities now masks by Parcels, where before it masked by the original Countries. Nothing is kept, and collision_left stays 0, so no notice fires. The project-wide path has the same gap: a report on Countries resolves through find_layer to the renamed layer, with no notice.
Suggested direction: when collision is true, also count references already named new (in the same scopes) and say so in the collision notice, or keep the rename from making them ambiguous. A regression test is needed: the existing layer_rename_never_redirects_a_table_to_another_layer_of_the_new_name only covers references to old.
References that already name the destination are silently redirected (confidence ~65%). layer_by_name returns the first case-insensitive match. When a rename makes two layers share a name, only references to the old name are counted. Example: [Parcels, Cities (mask "Countries"), Countries], renaming Parcels to Countries. Cities now masks the renamed layer, and no notice fires. Project-wide references (reports, models, workspaces) have the same gap. Posted inline at crates/engine/src/cmd/layer.rs:4721. A regression test for this case is needed.
Security
None found.
Performance
None found. The work is a few linear passes over the layers, layouts and project lists.
Quality (nits, grouped)
The notice for project references kept because the active map has a duplicate old name says "layer reference(s)… in this map", which doesn't name the report, model or workspace. Confidence ~40%.
references_follow_layer is about 120 lines with three near-identical notify blocks. The shared counter closures make the flow harder to follow.
The comment at line 54 ("Preserve the existing case-only mask spelling update") is slightly misleading, since the early return also skips relationships, topology and layouts. Those are cosmetic under case-insensitive lookup.
AGENTS.md
No violations found in the changed code. No unwrap, expect or panic in non-test code. Notice text uses NoticeText::format with literal project names. Notices use notify_text. The new tests exercise both the notice and undo paths.
Already raised, left alone (7 earlier concerns on this PR)
The mask-loop ambiguity, the project-wide redirect, the duplicate-old-name notice and the case-only skip are addressed by the author's fix commit or are deferred, so I did not re-raise them.
The clean-rename no-notice test, the narrowing of the stale-name check, and the extra fixture assertions were each deferred by the author to the release quality pass.
Checked: the full diff, the staged PR metadata and prior threads, the rename path in layer.rs (rename runs before references_follow_layer, so old_present and collision see post-rename state), the ElementKind, MapSeries, TopologyRule and Elevation definitions, layer_by_name and find_layer_map, and a repo-wide search for other typed layer-name fields. I could not compile or run the tests, since I have no shell in this session.

Update elevation and Map Series references on a case-only rename.
The selectors compare names case-sensitively. After a case-only rename, the applicable selector can show no selected layer even though the reference still resolves.
For an unambiguous name, update elevation and series references for the active map before returning:
Suggested fix
- // Preserve the existing case-only mask spelling update; other references still resolve.
if case_only {
+ if s.map().layers.iter().filter(|l| l.name.eq_ignore_ascii_case(old)).count() == 1 {+ if let Elevation::Surface(layer) = &mut s.map_mut().editing.settings.elevation {+ replace(layer);+ }+ let map_name = s.map().name.clone();+ for layout in &mut s.project.layouts {+ if let Some(series) = &mut layout.series+ && layout.elements.iter().any(|e| {+ e.id == series.frame+ && matches!(&e.kind, ElementKind::MapFrame { map, .. } if map.eq_ignore_ascii_case(&map_name))+ })+ {+ replace(&mut series.layer);+ }+ }+ }

Summary
Renaming a layer leaves typed references in layouts, reports, models and editing settings pointing at its old name. Carry those references with the renamed layer, including map series, relationships, topology rules, elevation surfaces and imagery workspaces.
Map-local references follow only their map. Project-wide references stay unchanged when another map has the old or new name. A destination-name collision also keeps affected references unchanged, with a counted notice explaining how to choose the intended layer. Script text, history and untyped tool parameters are left intact. Undo restores the layer name and its references together.
Testing
Passed
cargo xtask ci(5,365 passed, 0 failed, 22 ignored), therustgis-webWebAssembly build and all pre-commit hooks on9e03e84d.Five focused regressions cover the typed reference categories and undo, references in two maps, and destination-name collisions within and across maps, and counted references retained on a duplicate old name, including layer masks. The mask regression checks that the combined count is two and Undo restores the complete project state. Rendered and inspected the actual ambiguity notice with
ui_shot.UI evidence
