InvCatalogue

Changed

• Changed the repo and Fabric metadata license to LGPL-3.0-only to match the Modrinth projects.
• Added AGENTS.md with the project workflow for updating TODO.md, updating this changelog, verifying, and committing after each major change.
• Recorded the split and multi-version migration roadmap in TODO.md so it survives future context compaction.
• Added the initial Core foundation with shared mod id/logger ownership and event contracts for namespace changes, container snapshots, and inventory snapshots.
• Routed container/inventory snapshot handling and namespace-change handling through Core events, with Search and Catalogue now subscribed via feature bridge classes.
• Split catalogue and world-profile command implementation into separate command classes.
• Moved split-mod commands to feature-specific roots: /inventorycatalogue ..., /inventorycatalogue world ..., and /inventorysearch world ....
• Split sort/search screen-button ownership and added separate Core/Search/Catalogue client entrypoints as preparation for public modules.
• Added Gradle subprojects for Core, Sort, Search, and Catalogue. The three public feature jars now build separately and each nests the shared Core jar.
• Added collectReleaseJars and updated buildAllMods so publish-ready Sort, Search, and Catalogue jars are collected under build/release/<profile_id>/.
• Added Minecraft version profiles and upgraded the Gradle wrapper to 9.4.0 so 26.x migration profiles can be configured separately from the current release target.
• Extended Minecraft version profiles into compatibility-group build profiles with profile_id, minecraft_dependency, modrinth_game_versions, and compat_group metadata.
• Release jars now collect under build/release/<profile_id>/, and verifyReleaseJars checks generated Fabric metadata against the active profile.
• Added src/compat/<compat_group>/ overlay wiring for version-specific API adapter sources.
• Added separate public mod icon assets for Inventory Sort, Inventory Search, and Inventory Catalogue, and wired each module's Fabric metadata to its own icon.
• Added CI validation tasks for supported and candidate Minecraft profiles, including a smoke-test matrix gate for publishable profiles.
• Added automated client smoke launches through a dedicated smokelaunch project. CI now launches packaged release jars as Sort-only, Search-only, Catalogue-only, and all-three installs across the validation runtimes.
• Added a 1.21.9-1.21.10 candidate compatibility profile that compiles and builds release jars with range metadata, and now passes automated client smoke launches on both 1.21.9 and 1.21.10.
• Added broad candidate compatibility groups for 1.21.6-1.21.8, 1.21-1.21.5, 1.20.5-1.20.6, and 1.20-1.20.4, with exact runtime smoke profiles for every covered 1.20.x and 1.21.x version.
• Added compatibility shims for older Minecraft API shapes, including chest neighbor lookup, window handle access, HUD pose/matrix calls, single-player server directory paths, item stack components vs tags, recipe book screen presence, mouse wheel method signatures, and older button render overrides.
• Recorded passing automated smoke results for the full 1.20.x and 1.21.x candidate matrix. These profiles remain non-publishable until deliberately promoted from candidate to supported.
• Added publishValidation and smokeTestSupportedClients as a fast supported-only pre-publish gate, plus smokeTestSelectedClients filters for local smoke-test spot checks.
• Added guarded Modrinth publishing automation for the three public projects, including dry-run upload planning, supported-profile-only publishing, token handling through MODRINTH_TOKEN, and a manual GitHub Actions workflow.
• Bumped the focused Modrinth validation release to 2.6.4 and corrected the InvSearch project id used by publishing automation.
• Moved target-specific custom button render hooks into 1.21.9-1.21.10 and 1.21.11 compat overlays while keeping the shared drawing logic in Core.
• Added COMPATIBILITY.md with the Minecraft version probe matrix and Modrinth listing recommendation.
• Confirmed the current split release jars should be published for Minecraft 1.21.11 only until version-specific builds pass compile and launch testing.
• Documented the compatibility-group profile strategy: one build profile may produce one jar for a tested range of Minecraft versions, with CI smoke testing required before Modrinth publishing.
• Expanded the roadmap so CI validation becomes step 8 and Modrinth publishing automation moves to step 9.
• Confirmed the rebuilt split release jars launch in normal launcher installs individually and together.

Fixed

• Fixed split release jars embedding the development-namespaced Core jar, which could crash client entrypoints in normal launcher installs. Public jars now embed the remapped Core jar and clean build verifies this.
• Corrected the Fabric metadata icon path to use the checked-in assets/inventory-sort/icon.png asset.
• verifyReleaseJars now checks that each public jar's declared icon path is present in the packaged jar.
• GitHub Actions now runs ciValidation, building both supported and candidate profile artifacts while keeping pending smoke tests out of the publishable set.
• Fixed the first 1.21.9-1.21.10 compile blockers by adapting dimension id access and avoiding version-specific minecart entity class imports in shared identity code.
• Fixed broad 1.20.x and earlier 1.21.x compile/runtime launch blockers by moving API-sensitive calls behind version-selected compat overlays.

Removed

• Removed unused Fabric template scaffolding: the unused InventorySort initializer, unused ExampleMixin, and unused client mixin config referencing the missing ExampleClientMixin.
