+- `solitaire_core::achievement` — `AchievementContext` + `AchievementDef` + `ALL_ACHIEVEMENTS` + `check_achievements`
+- `solitaire_core::GameState.undo_count` — tracks whether undo was used (for `no_undo` / `speed_and_skill`)
+- `solitaire_data::AchievementRecord` + atomic `achievements.json` persistence
+- `AchievementPlugin` — on `GameWonEvent`, build context from `StatsResource` + `GameState` + `chrono::Local` hour, evaluate all conditions, persist newly-unlocked records, emit `AchievementUnlockedEvent(id)`
+- `AnimationPlugin`'s toast resolves the event's ID to the achievement's name via `achievement_plugin::display_name_for`
+- New `StatsUpdate` system set lets `AchievementPlugin` order itself after stats are incremented
+- Deferred: `daily_devotee` (needs `PlayerProgress`), `comeback` (needs recycle counter), `zen_winner` (needs modes), `perfectionist` (needs max-score calc). Stubs can be added in later phases.

 ## What Is Next
 
-### Phase 5 — Achievements
+### Phase 6 — Progression (XP, Levels, Daily Challenges, Modes)
 
-- 20+ achievement definitions (`AchievementDef` in `solitaire_core`)
-- `AchievementRecord` persistence in `solitaire_data`
-- `AchievementPlugin` in `solitaire_engine` — evaluates unlock conditions on `GameWonEvent` / `StateChangedEvent`, emits `AchievementUnlockedEvent`, persists, shows toast
-- `AchievementUnlockedEvent` currently uses `String` placeholder in `events.rs` — replace with `AchievementRecord` when this phase starts
+- `solitaire_data::PlayerProgress` (XP, level, daily challenge streak, unlocked card backs/backgrounds)
+- XP award on `GameWonEvent` — base + speed bonus + no-undo bonus
+- Level formula (from ARCHITECTURE.md §13)
+- Daily challenge seed generation + completion tracking
+- Weekly goals (rotating set of mini-objectives)
+- Time Attack / Challenge Mode / Zen Mode — unlocked at level 5
+- After this lands, the `daily_devotee` achievement can be wired up
