feat(items): preserve random properties from creation to the client - #462
Conversation
📝 WalkthroughWalkthroughThis change adds random-property catalogues, weighted selection, stat effects, compatibility enchantments, and persistent random-property identifiers. The identifiers propagate through item storage, loot, trade, mail, auctions, transfers, shared payloads, and gateway projections. ChangesRandom property lifecycle
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to Random-property updates may leave invalid property pools, lose properties in gameplay flows, or prevent package-defined item templates from using property pools. These issues should be addressed before merge. Sequence Diagram(s)sequenceDiagram

- Around line 3869-3871: Update item_property::dump_sql to return its explicit
total rows written across all three property tables, thread that count through
build_dump_plan into family_stamps, and add it to the items family count; do not
use insert_row_count because game_item_random_property includes the text suffix
field.
In `@module/src/gameobject.rs`:
- Line 815: Update the chest loot creation flow around random_property_id and
select_loot_property so invalid loot entries do not propagate errors or abort
chest use. Handle missing templates, empty or malformed pools, and missing
random-property rows like creature loot: log the error, skip the affected entry,
and allow valid loot plus the chest state update to proceed.
In `@module/src/loot/mod.rs`:
- Around line 494-500: Update the loot insertion flow around
select_loot_property and game_corpse_loot().insert(...) to track a separate
inserted-row counter; use it for slot assignment and increment it only after
insertion succeeds, so failed property selection does not consume a slot.

Items currently lose the Random Property selected at creation. This Tracer imports Property Pools and enchantment effects, selects a property once, preserves it through item movement, and sends it in the client packets. Equipped properties add the current Strength, Agility, Stamina, Intellect, Spirit, crit, hit and armor terms. T2 will connect the remaining Stat Kinds to their combat and regeneration folds.
The importer reads the correct build 5875 Spell columns. The dependency's shifted field names otherwise classify most real effects as unknown. The general Spell importer repair is tracked separately in #460. All four World Import Profiles import 2,012 properties, 1,685 enchantment effects and 27,892 pool members in 772 pools from the supplied client archives and pinned ClassicDB dump. The 384 unsupported effect rows retain kind 0 and source spell references. Authored enchantments 7745 and 7748 keep their existing +3 Strength and +3 Stamina meanings.
Draft for the human review required by
docs/danger-zones.md:game_item_random_property,game_item_enchantment,game_item_property_weight. Effects retain separate slots and school masks.u32columns on ItemTemplate, ItemInstance, CorpseLoot, BuybackEntry, Mail, MailEscrow, Auction, AuctionHold, AuctionOperationReceipt and LootRoll. Existing items remain plain.realm_loot_op,realm_mail_commit,realm_mail_item_payout,realm_auction_commit_listingandrealm_auction_refund_listing; full generated binding comparison covers every file.A missing or invalid Property Pool refuses direct item creation before inventory changes. Loot creation logs that content defect and omits the affected item without leaving an empty loot cursor. Weights use exact hundredths and proportional bands in property-ID order; tiny weights may have no band at the 10,000-value resolution.
Checked source at
b23d90eonmain627327f: importer 345 tests; Module 1,496; Gateway 1,422; shared 156. The complete local Gateway run initially failed only the unchanged trace-file test because/tmp/gw-writer-crashbelongs to the service account. The final local run excludes that one test; CI retains it. Four Gateway tests remain opt-in in the ordinary suite.Build, formatting, strict workspace clippy across all targets and features, offline preflight with Wasm schema extraction, and the complete 973-file generated binding comparison pass. Private Standalone acceptance passes 9 property tests, 3 auction/loot-roll movement tests and 1 real Coordinator armor projection test.
Reproduce the property acceptance on private disposable Standalone fixtures:
The first command kills a tagged creature, verifies the selected loot property survives a pool change and pickup, then proves equip adds 70 health and 9 Spirit. It also checks crafting atomicity, mismatched stacks, buyback, mail/escrow replay, auction refund replay, a cross-Shard Transfer, large Spirit amounts and invalid-pool loot omission. The second checks the real Coordinator armor projection before equip, after equip and after the item breaks.
No existing Realm was accessed. Realm import, a stock-client suffix tooltip check and the remaining T2 Stat Kind folds are outstanding. Refs #31.
Model: GPT-6 Astra, high effort. Harness: Codex in T3.
