feat: record the materials each jewelry piece was made from

[XxFran10xX]

Summary

A goldsmith slot accepts any material of its type (a Golden Ring takes 4 gold of any kind), so the project recipe is not always what went into a piece. Recycler currently returns the listed recipe, e.g. rough gold for a ring made from shiny gold.

• Finished jewelry now records the materials actually deposited, as item path to amount, in the geminfusion:goldsmith_inputs PDC (JSON).
• GoldsmithProvenance.read(ItemStack) returns that map, or null for jewelry made before this change.
• The infused gem is not recorded, matching what Recycler already returns.

Recycler will read this in a follow-up PR (per-type return rates + "return what was used").

Testing

• New GoldsmithProvenanceTest (stamp, merge of duplicate paths, empty deposit, unstamped/unreadable items) and a stamp assertion on the jewelry output test.
• Local mvn verify: all tests pass and the new code is fully covered. The two GoldsmithStationStoreTest POSIX permission tests cannot run on Windows and were excluded locally only; CI runs them.

Summary by CodeRabbit

• New Features
  • Finished Goldsmithing pieces now retain a record of the metal materials and amounts used to craft them. Recycling can use this record to return the materials actually deposited, rather than those listed in the recipe. When multiple deposits use the same material, their amounts are combined in the record.

📝 Walkthrough

Walkthrough

Goldsmithing jewelry output now stores deposited material amounts as provenance on the finished item. A utility writes and reads this data through item persistent data. Tests and the README also describe the provenance behavior.

Changes

Goldsmith Material Provenance

Layer / File(s)	Summary
Provenance storage and reading src/main/java/net/tfminecraft/geminfusion/PDCKeys.java, src/main/java/net/tfminecraft/geminfusion/goldsmith/GoldsmithProvenance.java, src/test/java/net/tfminecraft/geminfusion/goldsmith/GoldsmithProvenanceTest.java	Adds a persistent-data key and methods that store deposited material amounts as JSON keyed by material path. Repeated paths are combined. Tests cover empty deposits and cases where reading returns null.
Jewelry output stamping src/main/java/net/tfminecraft/geminfusion/goldsmith/JewelryOutput.java, src/test/java/net/tfminecraft/geminfusion/GemOutputTest.java, README.md	Jewelry output stamps the item with the station’s deposited materials. The output test checks the stored provenance. The README describes finished pieces recording the materials used.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Suggested reviewers: ryanbarlow97

Merge Risk: 🔵 Low · up to c2b9f

The README describes recycling support that this repository does not provide, which may mislead players about what they will receive. Correct the wording before merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to c2b9f

The change records crafting inputs without adding material-return behavior or broadening crafting permissions. Current exposure is limited, but the saved data’s validation and compatibility rules need to be established before it controls recycling payouts.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated change affects jewelry metadata within the server’s goldsmith crafting flow. No repository-local path was found from the new reader to a material-return sink. External plugin use of the public API remains unverified.

Trust Boundaries and Controls

• observed — The interactive crafting path checks goldsmith permission, matches held items against server-configured material paths, and enforces material-type capacity before incrementing counts. The new stamp consumes station accounting rather than player-supplied JSON. The reader itself provides decoding, not an authenticity or payout-authorization check.

Resilience and Maintainability Implications

• inferred — Output delivery, station cancellation and persisted-state deletion are separate operations. An interruption between delivery and cleanup could leave replayable crafting state. This sequencing predates the PR; stamping occurs before delivery and introduces no current return consumer that increases its exposure.

Hardening Proposals

• proposed — Before recycling grants materials from provenance, define trusted metadata sources, allowed material paths, positive bounded amounts, schema compatibility and legacy fallback. Treat successful JSON decoding as insufficient authorization for a payout.

And stamps each piece before its way.

Their paths and counts the work will guide.

The rabbit hops; the task is done!}

Cover provenance forwarding with a nonempty deposit.

This fixture does not provide a nonempty GoldsmithStation deposit. The empty-map assertion would still pass if JewelryOutput.build always stamped an empty map. Stub one material deposit and assert its path and amount.

Suggested fix

+      GoldsmithMaterial material = mock(GoldsmithMaterial.class);
+      when(material.getPath()).thenReturn("m.materials.shiny_gold");
+      when(station.getDepositedByMaterial()).thenReturn(Map.of(material, 3));
       JewelryCraftResult result = JewelryOutput.build(station, player);
       assertNotNull(result);
       assertSame(out, result.getItem());
-      assertEquals(Map.of(), GoldsmithProvenance.read(out));
+      assertEquals(Map.of("m.materials.shiny_gold", 3), GoldsmithProvenance.read(out));
