SF_MagicExpansion 1.1.12

MagicExpansion 1.1.12 — Black Market cycle diagnostics (draft candidate)

This build preserves MagicExpansion 1.1.11 fishing announcement privacy and 1.1.10 restart-safe Black Market purchase receipts.

Operator diagnostics

• /magicexpansion blackmarket status requires OP and reads only the cycle marker; it reports whether the live and disk cycles match, are semantically identical with altered file bytes, differ in cycle ID/time, or are unreadable/missing.
• It prints trading lock state, safely decoded cycle IDs/start timestamps, and an in-memory count of locked player records. It does not expose players' purchases, item contents, or credentials.
• It does not perform an automatic migration, repair, reset, refresh, or transaction. The original fail-closed purchase path is unchanged.
• Regression tests cover missing, unreadable, same-cycle rewrite and different-cycle mismatches. Existing market transaction and fishing tests remain enabled.

Upgrade

1. Keep existing plugins/magicexpansion/black_market/ untouched and back it up, including cycle.yml and players/.
2. Replace the older JAR with the single versioned SF_MagicExpansion1.1.12.jar only after CI, checksum and staging verification; do not install two plugin JARs with the same plugin name.
3. Check /magicexpansion blackmarket status. A mismatch does not clear on demand. Investigate the real file and purchase ledger history before enabling trading.
4. Keep all existing configs and item IDs; this release changes no persistent schema, offer prices, rewards, fishing behavior, loot or public chat defaults.

Read docs/black-market-cycle-diagnostics.md for lock semantics and a recovery checklist.

Release gate: This is a draft version, not a publication, and the original affected production state has not been examined. Do not publish or deploy it until a clean CI build and an old-world read-only test prove expected behavior.
