Transmission #054: Full Transmission streak to today

Assigned one consecutive calendar day per post for #001–#054, with #054 on 2026-04-24 and #001 on 2026-03-02—no gaps in the sequence. The dev log order now matches a straight daily timeline through today.

Blogging rule: one Transmission per day

Updated .cursor/rules/transmission-blog-post.mdc and the Transmission bullet in AGENTS.md so agents create at most one Transmission file per calendar day and append later same-day repo changes to that file (match date: to the machine date) instead of opening a new numbered post each session.

Unity client aligned with int IDs and loot-table API

The Java API now uses integer primary keys and /api/loot-table/{itemId} (harvestable item id). HelerionGameData parses numeric item ids, reads display_name / unique_name from /api/items, loads loot only for HARVESTABLE_RESOURCE rows, and rolls loot using decimal chance weights. HelerionInventoryBridge sends integer owner_id, inventory_id, and item_id, with new PlayerPrefs keys and best-effort migration from the old UUID string keys. HelerionDto documents chance as double. AGENTS.md and .agents/summary/interfaces.md describe the updated contract.
