 - Sealed `TimelineEvent` records replacing raw `Map<String, Object>` for type-safe timeline events
 - Source organization plan executed (Tier 1 + Tier 2 package restructure)

+- Enum-based config settings model with centralized, typed config keys
+- Versioned config migration with one-time comment backfill for legacy config files
+- Frame-by-frame step controls during paused replay; step backward or forward one tick at a time via `⏮`/`⏭` inventory buttons (slots 6–7)
+- Variable playback speed controls during active replay; adjust with `⏪ Slower`/`⏩ Faster` inventory buttons (slots 6–7) using configurable step increments
+- Current playback speed displayed in the action bar as `[X.Xx]` during playback
+- New config keys `Playback.Speed-Step` (default `0.2`) and `Playback.Max-Speed` (default `1.0`) to control speed increment and upper bound
 - Binary replay storage now uses finalized `.br` archives with crash-safe append-log recording, lazy indexed loading, file/MySQL backend support, filtered export tooling, hidden benchmark/debug diagnostics, preserved recording start timestamps, startup recovery of orphaned temp logs, and temporary legacy JSON compatibility during migration
 - Replay protection metadata and admin commands for protecting and unprotecting saved replays from manual deletion and retention cleanup
 - Config-driven replay retention cleanup with duration parsing, scheduled scans, and protection-aware deletion skipping
