BlockLedger

BlockLedger 0.1.2

Player-Visible Changes

• Added safe crime reconstruction playback in an isolated CrimeReconstruction world.
• Added /blockledger reconstruct start, entry, case, preview, stop, and status commands.
• TNT placement and ignition are now represented as separate timeline steps where exact new data exists.
• Direct player actions now capture bounded nearby scene context so reconstructions rebuild the local scene instead of only isolated changed blocks.

Admin And Config Changes

• Added reconstruction settings for enablement, world name, NPC requirements, legacy eligibility, scene context bounds, record/radius/session limits, playback tick rate, cleanup, and viewer return behavior.
• Added blockledger.reconstruct and blockledger.reconstruct.admin permissions under blockledger.*.
• Playback requires NPCs fake-player support by default; BlockLedger still loads without NPCs and reports reconstruction as unavailable.

Fixes And Compatibility

• Ledger storage now migrates reconstruction metadata columns for future rows while keeping legacy lookup and rollback data intact.
• Legacy rows remain lookup/rollback-capable but are not treated as exact reconstruction evidence unless explicitly allowed by config.
• Playback guards cancel world edits, inventory interaction, damage, fire spread, explosions, and drops inside CrimeReconstruction.

Async Reconstruction Prep

• Reconstruction requests now create PREPARING sessions and return immediately instead of building and playing the scene in the command handler.
• Added /blockledger reconstruct view <session> plus clickable ready chat, so playback starts only after an authorized viewer accepts.
• Scene preparation now batches chunk loading and block/entity placement per tick with reconstruction.build-blocks-per-tick and reconstruction.build-chunks-per-tick.
• CrimeReconstruction now builds a safe viewing platform before readiness, cancels damage, and recovers falling viewers back to a platform.
• TNT and explosion playback now groups blast damage into one explosion frame with future explosion_group metadata and fallback grouping for older rows.
