Add shared user-data runtime and guarded cache persistence - #383
Adds a shared user-data runtime with guarded cache persistence, strict storage snapshots and lifecycle-safe retirement. Keeps the legacy user-data facade while coordinating native SQL writes with shared-cache generations.
This update preserves replay and callback ownership across cache replacement and retirement, and handles missing console/player identities without publishing invalid state. Regression tests cover the affected lifecycle, SQL and reward paths.
Stacked on #373. This remains a draft: released-dependency compatibility and full server/database acceptance are not complete.
Validation of this exact candidate:
Clean producer package: 2,151 unit tests and 2 packaged-artifact tests passed.
Current VotingPlugin consumer package: 3,061 tests, including one existing skip, and 8 packaged-artifact tests passed.
The three-case retirement regression passed against the corrected SDK; the same fixture retains the expected retirement failure against the previous SDK.
Independent review of the complete current PR change found no findings.
MCPerks integration remains in progress: its current-host test run exposed an outdated private-method reflection fixture. That test is being corrected without removing its assertions; earlier test-host results do not establish acceptance of this combination. Live shared-database, Paper and Folia acceptance remains pending. No release or deployment is included.
Summary by CodeRabbit
Bug Fixes
Improved reliability of reward replay and asynchronous retries, helping prevent duplicate awards and preserve selection details when resuming.
Improved shared-storage updates to handle concurrent changes, failed writes, and shutdowns more safely.
Player-name lookups now handle missing or blank names safely.
Console commands without a player identity now reject commands that require player-specific data, while allowing safe literal commands.
New Features
Added support for reporting asynchronous reward failures and for more explicit replay and storage capability checks.
This pull request changes reward replay metadata and console-command validation. It also coordinates integer mutations, cache snapshots, SQL writes, and storage lifecycle operations. The changes add capability checks and tests for these paths.
Backends report authoritative row-read, transaction, and column-name capabilities. Strict reads distinguish unavailable rows from complete rows. Cache population and replacement carry completeness state and preserve pending changes.

User-data reads and writes select caches by access mode. Integer mutations validate storage identities, coordinate with checkpoints, and track admitted work. Tests cover arithmetic limits, aliases, refresh races, and deferred changes.
Legacy batch and direct writes track commits and failures, filter superseded columns, and reconcile cache versions. MySQL and SQLite write paths apply persistence-aware handling and reject stale writes.
Storage replacement and shutdown coordinate with active legacy mutations. Replay transactions add a precondition-rejection exception. The SQLite JDBC dependency scope changes from test to provided. Tests cover transaction retries, completion callbacks, and shutdown retries.
Replay state distinguishes fresh and restored entries. Selection metadata is read and persisted using that state, and checkpoint callbacks receive whether selection metadata is present. Queued rewards store trusted or checkpoint provenance.
Dispatch captures and claims asynchronous failure observers. The failure handler invokes the observer and suppresses observer exceptions while retaining the original failure.
Console commands use shared placeholder expansion and reject unresolved player aliases or enabled scripts when player identity is absent. Replay snapshots skip re-expansion, and asynchronous command paths pass replay state and keys explicitly. Blank player names no longer trigger the affected Bukkit lookup paths.

Add a deferral test that keeps a valid recorded selection.
The new test passes only a stale selection key. Its replay state has no recorded selection. If addOfflineRewards dropped every selection key from the queued entry, both assertions would still pass.
Add a case that records a real selection in the replay state, calls addOfflineRewards, and asserts that the persisted entry still contains that selection key. This path is not covered by the existing checkpoint test.

Skip the case-folded ambiguity check for PostgreSQL.
PostgreSQL column names are case-sensitive, but the integer mutation path refuses any key that has a case-variant sibling in the cache. A PostgreSQL cache that holds both Points and points therefore rejects valid mutations of either key. Gate the check on the provider's case-insensitive column rule, as UserDataManager already does.

Resolve MySQL case variants in shared integer mutations instead of rejecting them.
Line 748 returns null for a MySQL operand whenever a differently cased key is cached, even when that key is the only spelling. The legacy path resolves that spelling with resolveSharedMysqlKey. The receipt then fails and nothing is applied. Resolve shared MySQL operands the same way, and reject only when resolution returns null.

Record notification failures in the legacy cache path.
tryMutateLegacyIntegers queues the change before it calls notification.accept. If the consumer throws, the method throws after the mutation is applied. A caller that treats the exception as a failed mutation can retry and apply the change twice. The shared path already records notification failures instead of rethrowing them. Apply the same handling here.

When cacheUserNow loses putIfAbsent to a placeholder, its snapshot is discarded, but the population still records success. If getCache checks completion after that point, it skips cacheUser, so the placeholder stays empty. Refresh the winning cache, or re-run population when putIfAbsent returns a non-null value.

Shared retirement then waits on sharedIntegerDrain until the lifecycle forces the storage timer down. Complete the receipt on this path so it releases the admission.

Do not complete the legacy receipt on the single timer thread.
finishLegacyIntegerMutation completes the receipt at UserDataManager.java:2211 before it schedules the next queued ticket at line 2213. Dependent callbacks can run inline on the timer thread. A callback that waits for that next ticket blocks the only timer thread, so the ticket never starts and the wait never ends. Scheduling the next ticket earlier does not avoid this, because the single timer thread runs the callback first.

Keep legacy cache-miss reads off the server thread.
On a platform thread, a DEFAULT read of a legacy user can miss in the cache. The read then falls through to sqlData.getInt or sqlData.getString. Both run a synchronous SQL read on the calling thread. Repository guidance does not allow blocking a Bukkit, Paper, or Folia server or region thread on database work.
A miss can occur when the legacy snapshot is cleared or unpublished (UserDataCache.java:1224, 1233). The read then returns the incomplete cache from getCacheWithoutStorage. The fix must keep the stored value correct. Returning the default would give wrong values for stored data, so that option does not fix the problem. The read needs a non-blocking path that still returns the stored value.

Do not ignore a refused cache retirement during backend replacement.
replaceBackend calls clearAfterFlush(), and remove discards the result of retireSharedCache. If a legacy integer mutation is pending for a user, retirement returns false and the already-retired cache stays in the map. A later population of that user binds the stale cache. When the storage type changed, configureSharedStorage throws "Shared user cache belongs to another storage generation".
Suggested direction
Make the replacement fail, or wait for pending legacy integer mutations, when any retireSharedCache call returns false. Do not publish the new backend while a retired cache remains in the map. Keep the per-user gate check in UserDataCache.configureSharedStorage unchanged.

Guard the SQLite direct update, or fail it, when the guard cannot be installed.
When ensureDirectGuard returns false, the existing-row UPDATE runs with plain ? assignments and no WHERE guard. Two admitted writes can then execute out of admission order, and the older value can overwrite the newer one. Keep the guard requirement, or reject the direct write, instead of falling through to the unguarded statement.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
If ensureDirectGuard cannot register its SQLite function, an admitted direct insert with mutable columns falls back to INSERT OR REPLACE. Replacing an existing row can discard its columns not included in this write.
The replacement row can lose those additional persisted values.
This can occur when: A direct write reaches a missing-row insert decision using a SQLite connection wrapper that cannot be unwrapped, while another writer has inserted that UUID with additional columns.

result rejects the write before building or executing the UPDATE; do not allow
it to fall through to plain assignments. Preserve the existing behavior when
legacy direct persistence is disabled.

## Change and PR workflow
Keep changes focused and avoid formatting churn. Before any commit, push, PR update, review reply, or other remote change:
1. run relevant focused tests;
2. run the full Maven package build;
3. verify the fresh artifact and test discovery;
4. run `git diff --check`;
5. inspect the complete base-to-HEAD diff for compatibility, concurrency, persistence, lifecycle, security, and packaging regressions.

## Compatibility-first change policy
Compatibility is the default acceptance criterion for every new feature, refactor, fix, storage change, and dependency change. Unless the task explicitly authorizes a breaking change:
- Preserve public and de-facto APIs, constructors, overloads, callback/threading behavior, configuration keys/defaults, serialized forms, database semantics, shaded packages, and reflection-visible names used by downstream plugins.

## Runtime invariants
5. Keep user identity and UUID resolution consistent across online/offline paths. Coordinate cache updates, database writes, resets, and shutdown flushing. Final shared-runtime retirement fences queued notifications before marking storage retiring; callbacks already holding lifecycle admission may finish and re-enter storage. The optional pre-storage shutdown stage must finish before native storage retirement. Platform cleanup and the completion hook may run earlier on deferred shutdown; consumers must retain their own persistence owner until their stage settles.

Make selectionPresent include lane-scoped selections.
notifyReplayCheckpointPersisted derives selectionKey from the injection key alone. A selection recorded with replaySelection(placeholders, lane, selector) is stored under a different key, so selectionPresent reports false even though a selection exists for that injection. The onReplayCheckpointPersisted Javadoc defines false as "no accepted replay selection exists for this injection." Either check every lane-scoped key for the injection, or narrow the Javadoc to state that the flag covers only unlaned selections. No safe localized diff is established, so none is proposed.

around lines 402 - 406:
Update `notifyReplayCheckpointPersisted` so `selectionPresent` reflects accepted
selections recorded by `replaySelection`, including lane-scoped selections,
using the existing lane-key derivation and lookup mechanisms. If all relevant
lane keys cannot be determined safely, narrow the `onReplayCheckpointPersisted`
Javadoc so `false` explicitly means no accepted unlaned selection exists; keep
the flag’s behavior and documented contract consistent.

Check getValuesIfComplete in the canonical-reader gate.
usesCanonicalValuesReader does not check getValuesIfComplete. A subclass that overrides only that method passes the gate, so its partial map is published as a complete shared row. A later integer mutation on a missing unregistered key can then start from zero and write that value back.

Current source update: c349c52 contains the provider-aware key handling, notification containment, placeholder-race refresh, callback-lane changes, queued-setter guards and refused-retirement handling discussed in the earlier threads. The associated regressions are included in the passing 2,151-unit/2-artifact producer run. Complete independent source review found no findings; hosted CI has not reported a run.
Two limits remain explicit:
An uncertain replay is retained behind its identity-bound fence instead of being reported as a definite failed transaction. Finite callback capacity does not guarantee progress for arbitrary blocking callbacks.
The exercised legacy DEFAULT cold-cache storage fallback predates this PR. The identical mocked three-case fixture passed on base b82620 and this head: legacy reads returned stored nondefault values, CACHE_ONLY did not read storage, and unpublished shared-backend reads failed closed without platform-thread storage access. This is not live database/platform acceptance or coverage of every invalidation interleaving. Nonblocking legacy caller behavior remains follow-up work.
The PR remains a draft for dependency delivery and outstanding runtime acceptance. No merge, release or deployment is implied.

Adds a shared user-data runtime with guarded cache persistence, strict storage snapshots and lifecycle-safe retirement. Keeps the legacy user-data facade while coordinating native SQL writes with shared-cache generations.
This update preserves replay and callback ownership across cache replacement and retirement, and handles missing console/player identities without publishing invalid state. Regression tests cover the affected lifecycle, SQL and reward paths.
Stacked on #373. This remains a draft: released-dependency compatibility and full server/database acceptance are not complete.
Validation of this exact candidate:
MCPerks integration remains in progress: its current-host test run exposed an outdated private-method reflection fixture. That test is being corrected without removing its assertions; earlier test-host results do not establish acceptance of this combination. Live shared-database, Paper and Folia acceptance remains pending. No release or deployment is included.
