The recording studio currently gives every character on one account the same editable library, and inherited work has no separate ownership authority. This change scopes libraries, selections and edits to the complete account/character reference while keeping original author attribution and every existing published edition ID, byte and disc unchanged. Publication quotas and cooldowns remain account-wide.

Reviewed-heir migration retains original files and backups, preserves unknown YAML metadata including nulls during later saves, and replays durable intents to fixed recipients. Estate delivery drains captured writers, checks the exact decision before each ownership effect and reports cumulative receipts; stale partial transfers stay blocked. Captured sessions guard menus, dialogs, recordings, previews and late saves, including outgoing cleanup after the session becomes noncurrent. Inherited overflow remains accessible and blocks new creation at the existing cap.

Validation: Java 21 tfmc-mvn -o -B clean verify, 381 passing Java tests and the unchanged 100% instruction/branch/line gates; actual published TLibs 2.3.0 compatibility fixture; 12 passing rollback CLI tests; 5 Docs tests and 901 links/anchors. Immutable publication uses a synced no-clobber link and forced directory ancestry, with race and partial-failure regressions. This proves durable project ownership; physical-disc delivery still has Paper inventory/world crash boundaries.

Paired documentation: TF-Minecraft/Docs#228

Every current/historical estate receipt binds its captured death, full source/recipient references and supported revision. Restored source IDs block all revisions, including WAITING/FROZEN. Replay validates XML duplicates, payload format and exact paths, and permits only ownership-envelope changes to project YAML. Offline rollback uses a safe duplicate-rejecting PyYAML loader, preflights the whole journal and requires a new recovery directory before restoring/removing project files.

Draft implementation only; no deployment, restart, merge or release. Rollback instructions and checked preview/apply tool are documented in the paired guide.

Release provenance verification: the existing tag workflow now passes the current pinned dependency lock to artifact staging, so build.json records the resolved application dependency inputs. YAML, exact pinned installer selection and actual helper staging with unchanged gated JARs pass; existing legacy fixture locks remain separate. This workflow-only change does not alter runtime code or require another Java build.

📝 Summary

Summary by CodeRabbit

  • New Features

    • Studio projects are associated with individual characters, allowing separate project libraries for characters on the same account.
    • Project ownership can follow eligible character heirs, with safeguards for transfers and interrupted operations.
    • Added a tool to inspect ownership changes and safely roll back eligible transfers.
  • Bug Fixes

    • Studio actions and queued edits are stopped when a character session is no longer current.
    • Project data is preserved during ownership changes, including unknown fields and existing track data.

Studio projects now use character identities and character-scoped storage. Session tokens gate studio actions. The changes add journalled migration and estate transfers, durable file operations, and a CLI for inspecting and applying journal rollbacks.

Changes: Character-scoped studio and ownership

Layer / File(s) Summary
Character identity and session-bound actions
.github/compatibility/tlibs-2.3.xml, .github/workflows/*, pom.xml, src/main/java/net/tfminecraft/musicalinstruments/studio/StudioIdentity.java, CharacterStudioBridge.java, StudioMenu.java, StudioDialogs.java, src/main/resources/plugin.yml, src/test/java/net/tfminecraft/musicalinstruments/InstrumentPluginTest.java, src/test/java/net/tfminecraft/musicalinstruments/studio/StudioBridgeTest.java, StudioDialogWorkflowTest.java, StudioMenuTest.java
The build adds pinned TLibs setup and an older API compatibility fixture. Studio identity tokens represent character sessions. Menus and deferred actions check that a token is current before acting.
Character-owned project persistence
src/main/java/net/tfminecraft/musicalinstruments/studio/RawYaml.java, DurableFiles.java, StudioStore.java, src/test/java/net/tfminecraft/musicalinstruments/studio/StudioStoreTest.java, StudioStoreRecoveryTest.java
Projects use character-scoped paths and owner authority checks. Saves preserve unknown YAML fields. Durable file operations publish and delete files. Storage tests use the character-projects layout.
Character-aware studio service
src/main/java/net/tfminecraft/musicalinstruments/studio/StudioService.java, src/test/java/net/tfminecraft/musicalinstruments/studio/StudioCharacterTest.java, StudioServiceTest.java, StudioSaveQueueTest.java, TestIdentity.java
The service resolves project access, recordings, previews, and saves through character owners. It checks captured session tokens and carries owner references through save and cleanup paths. Tests cover character separation, stale sessions, ownership checks, and owner-aware saves.
Migration and estate ownership journals
src/main/java/net/tfminecraft/musicalinstruments/InstrumentPlugin.java, src/main/java/net/tfminecraft/musicalinstruments/studio/StudioOwnership.java, CharacterStudioEstate.java, StudioEstate.java, src/test/java/net/tfminecraft/musicalinstruments/studio/StudioOwnershipTest.java, StudioEstateTest.java, StudioOwnershipReviewTest.java, StudioOwnershipCostTest.java, StudioOwnershipPassTest.java, StudioShutdownHoldProbeTest.java
Migration and estate transfers use validated journals with replay and conflict checks. Estate settlement checks guards and save quiescence. Tests cover migration, transfers, receipts, retries, and invalid journal data.
Ownership journal inspection and rollback
tools/studio-ownership.py, tools/test_studio_ownership.py
The CLI validates journals and reports safe rollback candidates and conflicts. Apply mode backs up data, restores sources, removes targets, and archives journals. Tests cover preview, rollback, validation failures, and recovery-write failures.

Merge Risk: 🟡 Moderate · up to 89f9c

Studio edits still incur growing journal I/O as ownership history accumulates. Bound that cost before merging unless its operational impact is explicitly accepted.

- Around line 250-252: Repeated ownership checks scan and hash every journal
during each studio action; add an in-memory reservation index in
StudioOwnership, build it at start-up, update it in write(Path, Properties), and
revalidate it from disk only during hourly reconciliation or migration. In
StudioOwnership.java:250-252, replace the per-call journal scan with an index
lookup. In StudioService.java:141-141, resolve token(player) once per public
action and pass the resulting StudioIdentity.Owner through owner, requireOwner,
persist, and related helpers to avoid repeated writability checks.
