FragGuard

FG 26.3-1.2.0

Added

• Added the first Minecraft-native FragGuard GUI: typing /fg now opens an operator menu while all existing subcommands continue to work normally.
• Added GUI lookup setup with radius and time presets, condensed activity results, clickable result paging, activity detail screens, and exact raw-event drill-downs.
• Added structured Player, Action, and Material lookup filters generated from the selected lookup window, with no free-text filter parsing and no changes to stored history.
• Added presentation-only activity grouping that condenses nearby same-actor/same-action/same-material changes without deleting or rewriting any stored history rows.
• Added bounded database-backed GUI paging and streamed activity summaries so large history windows remain browseable without retaining the complete exact result set in one GUI session.
• Added configurable activity grouping thresholds and regression tests covering scaffolding-style chains, actor/action boundaries, time/distance boundaries, and preservation of every source event.
• Added GUI rollback controls with radius/time presets, conflict-protected or force mode selection, rollback preview launch, active-preview confirmation, and a paged browser with confirmation screens for undoable rollback jobs.

Changed

• Reviewed Paper 26.3 beta source compatibility and migrated GUI/message presentation from deprecated legacy Bukkit string/color APIs to Adventure components and serializers; event logging, block-entity snapshots, and rollback/undo APIs required no compatibility shims.
• Updated the Gradle wrapper from 9.7.1 to 9.8.0, SLF4J NOP from 2.0.19 to 2.0.20, and Mockito from 5.23.0 to 5.24.0, with regenerated dependency locks.
• Updated the development target to Paper API 26.3.build.136-beta and api-version: '26.3' following Paper 26.3's promotion to the beta release channel; the FragGuard feature version remains 26.3-1.2.0.
• /fg with no arguments now opens the GUI; /fg lookup, /fg rollback, /fg undo, /fg status, and /fg help remain available through the existing command path.
• Bumped actions/setup-java from 6.0.0 to 6.0.1

Fixed

• Fixed #81 by logging Paper 26.3 Shelf inventory swaps even when block data is unchanged, including connected powered shelves, and added Shelf-specific lookup/raw-detail, conflict-protection, rollback, and undo coverage while retaining the generic TileStateInventoryHolder snapshot format.
• Fixed #80 cross-version rollback conflicts by comparing compatible format-v1 block-entity snapshots after in-memory normalization through the current Paper item serializer; Paper 26.2 history, container contents, rollback snapshots, and undo data remain stored byte-for-byte and require no schema rewrite.
• Fixed #72 by giving rollback previews an explicit lifecycle: previews now expire on a guarded scheduled cleanup, are cleared on operator disconnect and plugin shutdown, are skipped when an async query finishes for an offline player, and expired tokens are filtered from tab completion.
• Fixed #70 by failing closed when legacy rollback history lacks a block-entity snapshot for a live supported block entity, while preserving normal comparison for ordinary blocks and force-mode override behavior.
• Fixed #69 by binding asynchronous rollback previews to the world captured when the query starts, so world changes during the query cannot mislabel preview, confirmation, overlap, or rollback-job metadata.
• Fixed same-tick coalescing merging different actors and actions by only combining consecutive, state-contiguous changes with matching attribution and action.
• Fixed timed-out queries falsely marking storage unhealthy by separating expected timeout and SQLite interrupt results from genuine database failures.
• Fixed redstone-primed TNT removal bypassing block history by logging TNTPrimeEvent transitions with specific cause attribution and suppressing duplicate generic history.
• Fixed dragon egg teleports being partially logged by recording the source and destination together under a dedicated teleport action.
• Fixed completed rollback jobs and snapshots accumulating indefinitely by expiring terminal jobs after the configured retention while preserving active and recoverable failed jobs.
