What changed

  • Keep every placed agent, ability, utility, text block, image, and lineup in attack-canonical coordinates.
  • Project positions and rotations at render/input boundaries when a page is shown on defense; switching sides now only changes page side state.
  • Reflect semantic anchors for scaled and compound widgets, and use measured bounds for dynamic text/image cards.
  • Apply the same projection to drag/drop, lineup guides, view-cone clipping, page transitions, screenshots, and video export pathing.

Backward compatibility

  • Bump the strategy format to version 97.
  • Migrate version 96-and-earlier defense pages from their previously mutated coordinates back to attack-canonical storage.
  • Reconstruct legacy text/image footprints so their visual positions do not shift during migration.
  • Preserve attack pages unchanged and keep the migration idempotent for current files.

Verification

  • flutter test --reporter compact — 424 passed, 1 existing skip.
  • flutter analyze — no new issues; one existing deprecation in pages_bar.dart.
  • Windows debug build completed.
  • Computer-use pass on an isolated, non-persistent harness covered attack/defense projection, measured multiline text relayout, directional rotation with upright internal content, compound offsets, view cones, defense drag inversion, and side round-trip. The real library was never opened.

Summary by CodeRabbit

  • New Features

    • Added consistent attack/defense coordinate and rotation handling across maps, placements, dragging, transitions, and previews.
    • Added automatic migration for existing defense strategies to canonical coordinates.
    • Improved sizing and positioning for placed text and images.
    • Added side-aware handling for custom rectangles and dynamic canvas placement.
  • Bug Fixes

    • Improved rendering and rotation of agents, abilities, utilities, lineups, and view cones across both sides.
    • Updated version information and folder icon registry.
  • Refactor

    • Removed legacy side-switching behavior from placement and provider workflows.

📝 Walkthrough

Walkthrough

The change introduces attack-canonical coordinate storage. Defense-side rendering reflects positions and adds 180-degree rotation. Legacy defense strategies migrate to canonical coordinates. Side switching no longer mutates placed objects.

Changes

Canonical coordinate system

Layer / File(s) Summary
Coordinate contracts and migration
lib/const/coordinate_system.dart, lib/const/placed_media_geometry.dart, lib/migrations/*, lib/providers/strategy_provider.dart, test/canonical_coordinates*
Adds side-aware position and rotation conversions, media footprint calculations, version-97 migration logic, and migration tests.
Placement and drag conversion
lib/const/transition_data.dart, lib/widgets/draggable_widgets/placed_widget_builder.dart, lib/widgets/line_up_placer.dart, lib/interactive_map.dart
Passes isAttack through position conversion, drop handling, drag handling, and placement-center updates.
Side-aware rendering
lib/widgets/draggable_widgets/canonical_positioned.dart, lib/widgets/draggable_widgets/**/*, lib/widgets/page_transition_overlay.dart, lib/widgets/line_up_*.dart
Projects canonical positions and rotations for the active side across placed widgets, line-up rendering, view cones, transitions, and previews.
Side state cleanup
lib/const/line_provider.dart, lib/const/placed_classes.dart, lib/providers/*_provider.dart, lib/page_transition/agent_path.dart, lib/services/video_export/video_exporter.dart, test/*switch_sides_test.dart
Removes provider-driven object flipping and obsolete switchSides APIs. Map switching now changes only isAttack.
Version updates and compatibility coverage
lib/const/settings.dart, lib/const/folder_icons.dart, pubspec.yaml, test/canvas_compatibility_fixture_test.dart, tool/generate_canvas_compatibility_fixture.dart
Increments version values and adds a deterministic v97 compatibility fixture with import and mirror assertions.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to 6666e

The PR changes stored strategy coordinates and migrates existing defense pages, so an interrupted or concurrent save could temporarily leave strategies at mixed migration states. The compatibility fixture may also require manual updates when new agents or utilities are added. The change is mergeable with explicit owner awareness and follow-up.

Greptile Summary

This change moves placed strategy content to a single attack-canonical coordinate system and reflects it only for defense presentation. Focused Flutter coverage passed for legacy migration, defense drag conversion, side switching, and dynamically sized media placement.

Confidence Score: 5/5

The verified migration, persistence, drag, and reflected-layout behavior supports merging this change.

Focused Flutter tests passed for every investigated failure mode: legacy defense migration, unchanged attack records, defense drag anchors, serialized placement stability after side changes, and dynamic card resizing on defense.

Files Needing Attention: No remaining issue was found in the verified files. Future changes to coordinate conversion or placement persistence should preserve coverage around lib/migrations/canonical_coordinates_migration.dart, lib/const/coordinate_system.dart, lib/const/transition_data.dart, and lib/widgets/draggable_widgets/placed_widget_builder.dart.

T-Rex T-Rex Logs

What T-Rex did

  • We encountered a PATH-related barrier when invoking Flutter, switched to the repo-provisioned Flutter SDK, and the targeted test run completed with all tests passing.
  • We ran the canonical coordinates migration tests and verified defense pages were migrated while preserving attack pages across all covered families.
  • We validated the reflected-coordinate conversions and anchor behavior at runtime, including screen-position reversal and the use of persisted, twice-rendered anchors during drag-end handling.
  • We validated provider logic and persistence by toggling isAttack via the MapProvider and confirming that serializing the placed collections preserves state across side switches, with tests reporting success.

65-68: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Decouple the frozen fixture assertions from live enums.

The fixture is frozen at v97, and tool/generate_canvas_compatibility_fixture.dart throws a StateError when Settings.versionNumber != 97. These assertions compare the frozen archive content against the current AgentType.values, UtilityType.values, and TraversalSpeedProfile.values. When a new agent, utility, or traversal profile is added, this test fails and the frozen fixture cannot be regenerated.

Consider asserting against the v97 name sets as literals, or restrict these checks to containsAll so new enum values do not break the frozen fixture. Keep a separate test that verifies the current schema coverage.

Also applies to: 90-93, 115-121
