Record gem and material inputs on alloy scrap

[XxFran10xX]

Failed alloy scrap currently records only its base, so Recycler cannot recover gems or other catalysts. Record every consumed ingredient and its quantity on each scrap item, while keeping the legacy base tag and base-only fallback for older scrap.

Validation: 13 focused metadata/forge tests pass locally, including real dropped-scrap provenance and multi-unit round trips. Full Linux CI must pass; the local full suite encounters pre-existing Windows file-lock failures in persistence tests.

📝 Summary

Summary by CodeRabbit

• New Features
  • Failed alloy forges now record consumed ingredients and their quantities on scrap for Recycler recovery. Existing base-item provenance is preserved.
• Documentation
  • Clarified that older scrap retains only its recorded base, and missing catalyst history cannot be recovered.

Walkthrough

Failed alloy forge scrap now records consumed station ingredient quantities in persistent provenance. The reader returns valid stored quantities and supports legacy base provenance as one input.

Changes

Scrap input provenance

Layer / File(s)	Summary
Store and read scrap inputs src/main/java/net/tfminecraft/advancedcrafting/objects/data/ScrapProvenance.java, src/main/java/net/tfminecraft/advancedcrafting/utils/PDCKeys.java, src/test/java/net/tfminecraft/advancedcrafting/ScrapInputsTest.java	Adds persistent storage and reading for ingredient quantities. The reader accepts positive integer quantities and falls back to the legacy base ID with a quantity of one when new-format data is absent. Tests cover input-reading cases.
Record forge inputs on scrap src/main/java/net/tfminecraft/advancedcrafting/objects/alloys/AlloyForger.java, src/test/java/net/tfminecraft/advancedcrafting/ForgerCoverageTest.java, README.md	The forge records counts of station ingredients on scrap. The forge test checks recorded inputs. The README describes current and legacy scrap provenance.

Merge Risk: ⚪ Minimal · up to 1fde3

This change records every consumed ingredient on failed-forge scrap and keeps support for older scrap. No actionable merge-blocking risk was identified in the supplied context.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 520ea

The change remains within the existing forge workflow and preserves legacy provenance. No introduced exploitable path was established, but deployed recovery behavior and metadata trust controls remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The inspected normal insertion path permits one base and up to four catalysts and rejects exact duplicate ingredient IDs. The changed write affects the resulting scrap item's resource provenance; downstream recovery exposure is not established.

Trust Boundaries and Controls

• inferred — The producer has station-derived provenance, but positive-value filtering alone does not authenticate metadata for resource issuance. Without the actual recovery consumer or deployment controls, player metadata-forging capability and a trusted recovery sink remain unresolved rather than a demonstrated attack path.

Resilience and Maintainability Implications

• observed — The new metadata write precedes scrap emission. Station removal remains after the forger returns, while breaking a valid station refunds its stored ingredients before removal. This ordering does not itself provide transactional recovery across interruption or failure after emission.

Hardening Proposals

• proposed — Before a recovery component treats this payload as authority to issue resources, define and enforce accepted provenance sources, ingredient identities, quantity bounds, malformed-data handling, and repeat-consumption behavior. This is a prospective integration safeguard, not an observed vulnerability.
