[1.1.2]

Fixed

• Build threaded Discord webhook message URLs from parsed URI components so edit and delete endpoints place /messages/{id} before existing query parameters, while preserving query values and handling trailing slashes correctly.
• Shut synchronization down cleanly by invalidating in-flight state mutations, dropping queued and retry work, cancelling delayed retries, and force-stopping the webhook HTTP client so late completions cannot write stale runtime state.
• Move player-list sorting, activity classification, Discord formatting, escaping, and pagination off the Minecraft server thread. Synchronization now captures only Bukkit-owned player/configuration data synchronously into immutable records before rendering and sending asynchronously.
• Keep normal edit-only synchronizations write-free when managed Discord message IDs are unchanged. Generated message state remains outside config.yml in atomic message-state.json, preventing synchronization from overwriting unrelated administrator configuration edits.
• Centralize startup and reload validation for webhook, activity, scheduling, debounce, toggle, header, and legacy message-ID settings. Invalid scalar values now produce field-specific safe warnings, scheduling values are bounded before tick conversion, invalid timestamp sources fall back to LAST_SEEN, and malformed or duplicate stored IDs cannot enter active state.
• Preserve version 1/2 message-state.json IDs and deferred legacy IDs from older configuration while binding them to the first valid configured webhook identity instead of discarding tracked messages.
• Retain existing tracked message state when the webhook is temporarily blank, placeholder, or otherwise unconfigured so restoring the same destination does not create duplicate messages.
• Include thread_id in the non-secret webhook state identity, including percent-encoded query-name forms, so changing Discord threads starts a separate managed message lifecycle while webhook token rotation preserves the existing one.

Changed

• Configure Dependabot to keep Gradle and GitHub Actions dependencies current on dev, while leaving the Paper API pinned for manual updates.
• Debounce join and quit synchronization requests with a configurable trailing-edge window so bursts of player activity produce one final update. updates.event-debounce-seconds defaults to 5 seconds, is clamped to 0-60 seconds, and can be set to 0 to disable debouncing; /lsd sync remains immediate.

Added

• Add deterministic loopback HTTP integration tests for the real webhook client, covering request construction, top-level message-ID parsing, Discord unknown-message recovery, rate-limit delays, and controllable delayed responses without contacting Discord.
• Add configuration boundary and migration regression tests covering legacy settings, scheduling limits, invalid timestamp values, webhook-secret redaction, and malformed or duplicate message IDs.
