fix: treat reset infused gems as infused and restore them

[XxFran10xX]

Problem

A player's Spinel showed as Spinel / Blank Gemstone with Projectile Damage: +4% still on it, and the goldsmith refused it ("You need an infused gem for jewelry"). The AdvancedCrafting converter lore on it was a coincidence: the converter only adds a PDC tag and lore lines and never changes the MMOItems displayed type.

The real cause is unsocketing. MMOItems rebuilds an unsocketed gem from its blank template, so the name, Infused Gemstone type and rarity lore are lost, while the rolled stat stays. UnsocketedGemRestorer puts the infused look back, but only when the host item has the gem's rarity stored in socket_rarities. Gems socketed before that store existed (or whose rarity id no longer exists) come back blank for good. The goldsmith then rejects them, and the infusion bench accepts them as blank gems, which would wipe the roll.

Changes

• InfusedGemValidator.isReset: a configured gem showing Blank Gemstone that still carries one of its configured infusion stats. Blank gem templates never have these stats (all 40 on Main checked), so this only matches gems that were infused.
• isInfused accepts reset gems, so goldsmithing works with them (the jewelry stat is read from the gem as before).
• Unsocket restore now also runs without a stored rarity; the gem gets Infused <Gem> with no rarity line or PDC instead of a guessed rarity (attribute influence makes the roll ranges overlap, so the rarity cannot be inferred). It now only targets reset gems, so it can no longer turn a genuinely blank gem of the same type into an infused one.
• The infusion bench restores a reset gem in hand ("This gem already holds an infusion. Its glow returns.") instead of infusing it again. This is also how players can fix reset gems they already have.
• Restored gems keep their stack size.

Restoring rebuilds the gem through MMOItems, so an AdvancedCrafting converter tag and lore on it are dropped (as with the existing unsocket restore); the converter re-tags it on the next click.

Testing

• mvn verify: all unit tests pass, 100% coverage on the changed classes (the two POSIX-permission GoldsmithStationStoreTest cases were skipped locally on Windows; CI runs them).
• TFMCDev01 bot test on the current 2.2.8 jar reproduced the bug: a Rare Infused Spinel socketed into a lute with its stored rarity wiped came back as Spinel / Blank Gemstone with its stat, and the goldsmith refused it.

📝 Summary

Summary by CodeRabbit

• Bug Fixes
  • Unsocketed gems can be restored even when their rarity is missing or unrecognised; rarity details are omitted when unavailable.
  • Gems that have lost their infused appearance are restored when they still contain infusion data, while gems without an infusion are left unchanged.
  • Already-infused gems are no longer added to an infusion station or consumed; their appearance is restored and the player is notified.
  • Restored items retain their original quantity, and items are left unchanged when rebuilding cannot be completed.

Walkthrough

Reset-gem validation now checks configured infusion stats. Cosmetic rebuilding and unsocket restoration support missing rarity data. The infusion event restores reset gems and stops before adding them to a station.

Merge Risk: 🔵 Low · up to 568dd

Only custom configurations permitting zero-valued rolls are affected; the checked-in ranges avoid this case. With such a configuration, a reset gem can be accepted for another infusion attempt, so the remaining risk is bounded.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 568dd

The recovery paths remain narrowly scoped and preserve existing crafting permissions and item-count controls. A bounded rollback concern remains: reset gems deposited directly into unfinished jewelry projects may not be recovered by the older version. Preservation of rolled stats during rebuilding also depends on behavior that was not independently verified.

Retained concerns

• Low · reliability · inferred: Rollback to the comparison base can omit a newly accepted reset gem from an unfinished goldsmith project. The head accepts a blank-labelled stat-bearing gem and deposits an unchanged one-item clone; persistence serializes that clone. The base recovery path rejects Blank Gemstone and leaves the station without its saved gem, making it unavailable through normal project refund. This is limited to directly deposited reset gems in unfinished projects; gems restored before deposit have the infused label accepted by the base.

Security review details

Security Blast Radius

• inferred — Direct repair writes are confined to the triggering player's held or inventory stack. Expanded eligibility also reaches shared goldsmith projects and their saved state, with a one-gem-per-project limit. The inspected paths do not establish new cross-player inventory-writing authority.

Trust Boundaries and Controls

• observed — Item acceptance uses configured MMOItems identity and NBT stat values rather than visible lore alone. Goldsmith interactions retain the existing permission gate. The configured-stat predicate assumes genuinely blank templates cannot carry those stats; production template and other stat-producer behavior were not supplied for independent verification.

Resilience and Maintainability Implications

• observed — Delayed unsocket recovery still selects items through a player-keyed, one-shot inventory snapshot and same-type slot or amount heuristics rather than a durable recovered-item identity. This selection design predates the PR; missing-rarity scheduling expands its use while the new reset predicate narrows eligible targets. Interrupted execution and competing same-type recoveries remain unverified, not demonstrated new exploits.

Hardening Proposals

• proposed — Verify the recovery contract against the deployed MMOItems builder and blank templates: successful rebuilding should preserve rolled stats and required metadata, and every genuinely blank producer should lack the configured infusion-stat markers used for admission.

• Autopilot · Keep fixing CodeRabbit findings and required CI, and resolving merge conflicts

TFMCDev01 bot test

Same bot across both runs (~/gemreset-test/test.js on the host). Socketing into an Abyssalite Lute, unsocketing with UNSOCKET_TOOL; "legacy" = the lute's geminfusion:socket_rarities wiped after socketing, like gems socketed before the store existed.

2.2.8 (current Main jar), bug reproduced

• Rare Infused Spinel (proj 3.5646) socketed (legacy), unsocketed: comes back Spinel / Blank Gemstone, proj 3.5646, no rarity. Same for a Common one.
• Goldsmith Golden Ring with that gem: "You need an infused gem for jewelry."

This branch, with those two reset gems

• Goldsmith: a genuinely blank Spinel is still refused; the reset gem (also stamped with the AdvancedCrafting converter tag) is accepted; Golden Ring crafted (100% / Masterwork), ring has projectile damage 1.3112 = 3.2781 × 0.5 minor × 0.8 attribute.
• Infusion bench with the other reset gem: "This gem already holds an infusion. Its glow returns."; no gem added to the bench; gem is now Infused Spinel / Infused Gemstone with proj 3.5646 unchanged.
• Fresh infusion still works (Common Infused Spinel). Socket + unsocket with stored rarity: comes back Common Infused Spinel with rarity and roll kept.
• Legacy socket + unsocket: comes back Infused Spinel / Infused Gemstone with its roll (previously blank).
• No GemInfusion warnings or errors in the server log.
