+> **Fun + living-world milestone (2026-06-13, also committed, not pushed):**
+> The core game loop was shallow, so a second pass made combat actually fun and
+> wove in more load-bearing LLM:
+> - **Leveling scales power** — level+spent points → rank/HP/damage (`statBonuses`); a
+>   level-up gives an immediate live buff + full heal; attribute points spendable (+HP/+DMG).
+> - **Escalating waves** — foes ramp with time+kills; Elite (2.4× HP) and Champion boss
+>   (4.6× HP, bigger sprite) on kill milestones, worth far more XP.
+> - **Hit juice** — hitstop + screenshake (processLog onHit/onDeath hooks); existing red flash.
+> - **Dodge roll** — Shift / ⟲ button → fast i-frame dash (engine `invulnUntil` in dealDamage).
+> - **Combat HUD** — adrenaline meter, per-skill ready-dim, top threat badge (surfaces the
+>   engine's hidden adrenaline/condition/combo depth).
+> - **Live combat state in chat** — `buildStateTurn` takes a live snapshot (HP/threat) so a
+>   fighter answers aware of its current wounds, not just persisted history.
+> - **Death after-action + war-diary recap** — on death, a report (kills/threat/levels/time)
+>   + an in-voice LLM recap of the run, banked to the hero's memory (feeds chat).
+> - **Personal-best records + shared Chronicle** — a record to beat per hero; fallen heroes'
+>   legends post to a world feed shown on the after-action (the world feels populated).
+>
+> Still open (good next swings): loot/rewards, the bigger living-world LLM features
+> (social fabric/relationships, off-screen evolution, skill+soul mutation, an LLM director).
 
 **Goal:** turn each fighter from a static persona into a living, evolving character that
 **levels up**, **forges unique skills** (code + flavor + art), and you can **talk to**
