MINECRAFT JAVA 26.2 -> 26.3 MIGRATION RECORD
================================================
Pack: Enchanted_Tool_Expansion_V2.2.9_Minecraft_26.3
26.2 source: Enchanted_Tool_Expansion_V2.2.8_26.2_Harvester_Interplant_Full_Till (1).zip
26.3 output: Enchanted_Tool_Expansion_V2.2.9_Minecraft_26.3.zip
Date updated: 2026-09-15
Main systems: Excavator, Harvester, Quarry; item modifiers; statistic/advancement input bridge; villager trades.

DISCOVERY / PROTOCOL
- Original 26.2 source preserved.
- Two independent full compatibility scans were run from the source before editing.
- Both scans independently reproduced the same migration scope: 20 compatibility runtime files identified on both independent scans.
- Compatibility changes were kept separate from architecture optimization.

MIGRATION CHANGES MADE
- pack.mcmeta: Data Pack 107.1 -> 121.0; release label v2.2.9 / Minecraft 26.3.
- 15 top-level-list item modifiers wrapped in minecraft:sequence; nested loot-function function -> type.
- 1 single-object item modifier: function -> type.
- 3 input advancements: old player predicate lists replaced by explicit minecraft:all_of; nested entity_scores predicate discriminator condition -> type.
- Direct numeric trade-provider values preserved because scalar constants remain valid; no speculative trade rewrite.
- Runtime load banner updated to v2.2.9 / Minecraft 26.3.

STATIC VALIDATION
- Target metadata is Data Pack 121.0 with min_format/max_format [121, 0].
- All JSON resources parse successfully.
- ZIP integrity check passes.
- Post-edit targeted schema scan finds no remaining known 26.2 migration markers in the converted contexts.
- Files outside the intentional migration/release-metadata set remain byte-for-byte identical to the 26.2 source.

REQUIRED 26.3 RUNTIME / FUNCTIONAL VALIDATION
- Load/reload; test Excavator, Harvester, and Quarry triggers; verify Harvester 3x3 till/replant/interplant behavior; test modifier-produced books/tools and villager trades; regression-test level reading and exact-hit capture.
- Inspect latest.log/server console for pack-format, JSON, registry, predicate, advancement, item-modifier, loot, and function-load errors.
- Run /reload after initial successful load and regression-test systems intentionally left unchanged.

STATUS: STATIC MIGRATION COMPLETE — REAL MINECRAFT JAVA 26.3 SERVER VALIDATION PENDING
Do not mark this pack 26.3 READY until the target-version runtime validation gate passes.
