ForceBlend (PoC)

GitHub Branch

User experience

• Added a read-only pre-analysis that counts scanned chunks, affected chunks, deferred chunks, and affected regions before any write.
• Added an estimated processing time based on the current analysis, with a conservative fallback when no useful sample exists.
• Added four post-analysis choices: apply and enter; back up, apply and enter; enter unchanged; or cancel.
• Added live analysis, backup, validation, and processing progress for larger jobs.
• Progress can show percentage, chunks or regions completed, ETA, active region files, and chunk throughput.
• Added a completion notification where desktop notifications are available.

Configuration and backup

• Added optional Mod Menu integration without making Mod Menu a runtime requirement.
• Added persistent settings for automatic analysis, automatic backup, detailed logs, per-opening chunk limits, and processing threads.
• Defaults are automatic analysis on, automatic backup off, detailed logs off, unlimited chunks, and all available processors.
• Settings are stored in <game>/config/forceblend.properties using atomic replacement.
• Added complete world ZIP backups under <game>/backups/forceblend/<world>/<timestamp>.zip.
• Backups reject unsafe links and overlapping source/destination paths, keep timestamp collisions, clean partial files, and are discarded if the world changes during creation.

Processing and safety

• Split processing into a reusable immutable plan and an apply phase, so the confirmation dialog does not require a second full analysis.
• Added deterministic per-opening limits; deferred chunks remain eligible on later world opens.
• Region analysis, stale-plan validation, and application can use multiple worker threads while each region file still has a single writer.
• Added stale-plan checks for the region set, file metadata, Anvil headers, planned chunk outcomes, and external chunk payloads before replacement.
• Preserved temporary-file region assembly, forced writes, validation, unchanged-region avoidance, and cleanup on failure.
• Added recoverable multi-file commits for changed external .mcc chunks, restoring the original sidecars and region if any replacement move fails.

Verification status

• The automated test suite passes for the 1.1.0-beta.1 code line.
• This beta has not yet been re-tested in game on 1.18.2 or 26.2. Do not treat its automated status as a gameplay verification.
• Stable 1.0.0 remains the release verified in game on Minecraft 1.18.2 and 26.2.
• No performance benchmark claim is made for this beta.
