Patch 5.0.6 - Build Mode ignore_base_rules, Test Isolation

Release Date: May 5, 2026 Version: 5.0.6 Type: Maintenance / Build Mode / Test Isolation Release

Highlights

Build mode now honors ignore_base_rules — Placeables configured to ignore base placement rules now correctly opt out during build-mode preview setup and validation
Test isolation hardened — Shared test resources no longer leak stale state across suites; deterministic cleanup through actual runtime entry points
Collision exclusion cleanup deterministic — Build preview teardown, manipulation cancel, and successful placement finalization all clear exclusion state correctly
1715 tests passing — 100% passing, 0 flaky

Fixed ignore_base_rules ignored in build mode — Placeables configured to ignore base placement rules now correctly opt out during build-mode preview setup and validation. Previously, the build path dropped this flag, so base collision and placement rules were still applied even when the placeable explicitly disabled them.
Optional placement rules no longer emit false setup failures — Entering build mode with no applicable rules now remains valid. The indicator pipeline no longer reports missing-rule or missing-indicator issues when there is nothing to validate.

Fixed shared test resources leaking stale state — Test environments now reload or rebind fresh TileMap, targeting, and level-context resources per scene so process-order execution does not corrupt later placement and manipulation suites.
Fixed manipulation and build collision exclusions leaking — Cleanup now consistently clears exclusion state through the actual runtime entry points, covering build preview teardown, manipulation cancel, and successful placement finalization.
Fixed platformer and smithy demo regressions in full-suite order — Demo suites now normalize targeting state and rebuild their per-test collision setup so their full-project behavior matches isolated runs.
Fixed RuleCheckIndicator exclusion regressions leaking state — The exclusion regression suite now frees tracked test nodes, clears targeting exclusions, isolates its collision mask, and asserts the valid_changed payload so signal checks remain deterministic.

Build-mode regression coverage for ignore_base_rules — Integration test proving that a placeable with ignore_base_rules = true ignores failing base rules and validates using only its own placement rules during build mode.

Manipulation configuration flow coverage — Focused regressions for move_suffix, physics-layer disabling/restoration during move start, cancel, and successful placement, plus no-rule manipulation validation paths with empty base rules.

Plugin entry-point and configuration coverage — Focused tests for plugin.cfg, editor-plugin script wiring, release version consistency across README surfaces, and the default input-action setup entry point.

Typed building test-isolation state — Replaced anonymous helper dictionaries with a local typed state object so setup and cleanup failures are easier to inspect in the debugger.
Direct collision-exclusion regression coverage — Focused regression tests asserting collision exclusions are created and cleared correctly during build and manipulation workflows.

Build preview setup forwards the placeable rule policy correctly — BuildingSystem.enter_build_mode(), instance_preview(), and _try_setup() now consistently pass the placeable’s ignore_base_rules flag into indicator setup and rule validation.

Plugin metadata bumped to 5.0.6 — Updated plugin.cfg, guide frontmatters, and README version surfaces to match the current release for both the core addon and the inventory addon.
