+All project tests and test-only helpers belong under `VotingPlugin/src/test/java/com/bencodez/votingplugin/tests/`, with package `com.bencodez.votingplugin.tests` or a meaningful subpackage. Keep paths and package declarations aligned, and update cross-test imports, resources, and build selectors when moving tests. Preserve package-phase artifact checks and test discovery. Do not widen production APIs to make tests accessible; use narrowly scoped test-only reflection for non-public seams.

 Assign one owner to Maven validation in each worktree. Never run concurrent Maven commands in the same worktree, including focused tests alongside a clean/package build: compilation and cleanup share `target/` and can invalidate each other.

 - Preserve queued votes across saturation, reload, runtime replacement, scheduler rejection/cancellation, shutdown, and restart; overflow handling must be bounded, durable when promised, and observable rather than silently dropping work. Scheduler admission is never proof of durable ownership.
+- Local Votifier captures remain owned after STARTED until normal callback completion or confirmed overflow transfer. Transfer execution stays fenced while the original callback runs; successful non-interrupted completion reconciles only its exact occurrence, while interruption/exception or failed transfer retains bounded recovery ownership. A callback completing after the final overflow snapshot is an explicit uncertain reconciliation case; a retired queue must not overwrite a successor, and ordinary partial external effects retain the existing at-least-once boundary.
