feat: full character creation, personality traits, and session quality-of-life

Character creation:
- Full RQ3 Previous Experience wizard (4-step: identity, characteristics,
  culture/occupation/skills, review+save) with all 29 occupations across
  4 cultures; skills computed as base + category modifier + years × multiplier
- Character sheet expanded to show culture, occupation, derived stats (HP/FP/MP/
  DB/SR), all 7 skill category modifier badges, computed skill percentages grouped
  by category, weapon attack/parry %, hit locations with armour AP
- Location/destination tracker on character sheet (auto-saves on blur)
- parry_percent stored on combatant_weapons

Personality traits:
- 24 predefined traits (Brave, Greedy, Cautious, etc.) each rated 0-100%
- Trait → action bias map drives scene choice weighting
- rollPersonalityAction() rolls d100 per trait, sums biases, returns suggestion
- Trait editor (pill UI) on both character sheet and NPC view
- Adventure tab: Roll Personality button fires traits, highlights suggested choice

Tables and data:
- Import RQ3 character creation tables (Culture d8, Occupation d100 ×4, Craft
  sub-tables, Language Proficiency, Dropped Oil Lamp, Aging, Armor Points)
- Cross-table links: Culture → Occupation, Barbarian/Civilized Crafter → Craft
- Fix rollOnTable to use actual dice notation instead of flat random row index
- Remove unused resolveHeadInjury function

Session tools:
- Clear All button wipes all session data (characters, NPCs, enemies, combat,
  adventure, log) while keeping tables and spell mappings
- PATCH /api/characters/:id/traits and /api/npcs/:id/traits endpoints
- GET /api/rules/personality-traits reference endpoint
- POST /api/adventure/personality-roll endpoint

 ## High priority (mechanics gaps)
 
-- [ ] Call `resolveHeadInjury()` in the attack handler when a Head hit penetrates armor
+- [x] Fix `rollOnTable` to roll the table's actual dice notation instead of picking a flat random row — now affects the adventure engine (Culture Table, Occupation Tables) where unequal row ranges matter
 - [x] Resolve stuck-weapon follow-up after impale/slash special hits (`attemptWeaponRemoval`, `removeStuckWeaponFromSelf`, `removeStuckWeaponWithFirstAid`)
 
 ## Medium priority (missing features)
 
+### Adventure / CYOA
+- [x] Add character location / destination tracker — where the PC currently is and where they are heading; used to auto-select which encounter table to roll
+- [ ] Add Layer 3 (and possibly Layer 4) sub-tables to the Norse encounter tables so scene descriptions cascade into richer detail
+- [ ] Add a Previous Experience step to the PC generator (culture → occupation → skills, magic, equipment) using the imported occupation tables
+- [ ] Wire PC weapon skills into adventure scene choices so "Fight" shows the correct attack %
+- [ ] Persist scene history so the adventure log reads as a continuous narrative
+
+### Combat
 - [ ] Build strike-rank round scheduling UI (round counter, Next Round button, SR-ordered action display using `buildStrikeRankSchedule`)
+
+### Other
 - [ ] Add API routes and UI for the experience/improvement system (`markWeaponExperienceChecked`, `updateWeaponSkillPercent`, `applyImprovement`)
-- [ ] Add Layer 3 (and possibly Layer 4) sub-tables to the Norse encounter tables so rolls can cascade deeper
-- [ ] Add a character location / destination tracker — where the PC currently is and where they are heading (used to contextualise encounters and travel events)
-- [x] Player character generator — stat rolls, derived stats, skills, weapons, hit locations; needed for combat and skill checks
 
 ## Low priority (polish)
 
 - [ ] Wire up the export reminder modal (show on `beforeunload`, hook up Export Now / Leave Anyway / Cancel buttons)
 - [ ] Add `DELETE /api/spell-mappings/:id` endpoint and a spell mapping management UI
 - [ ] Add weapon and spell editing forms to NPC stat block view (currently only available for enemies)
+- [ ] Add item editing (change qty inline) and ENC-per-item display to inventory UI
 
 ## Correctness fixes
 
-- [ ] Fix `rollOnTable` to roll the table's actual dice notation and match the range, instead of picking a flat random row index
 - [ ] Fix `state.dirty` being set to `true` on GET requests
 
 ## Cleanup
 
 - [ ] Remove dead `state.reactionType` from frontend state
+
+## Done
+
+- [x] Player character generator — random/deliberate/combined methods, correct RQ3 derived stats
+- [x] Fix total HP formula (was CON+SIZ, now ceil((CON+SIZ)/2)); fix hit location HPs
+- [x] Skill category modifiers (all 7, primary/secondary/negative influences) + fatigue points
+- [x] Inventory system — items with ENC tracking, effective FP = STR+CON − total ENC
+- [x] Adventure scene engine — procedural CYOA choices resolved via skill checks; scene state persisted
+- [x] Import RQ3 character creation tables (Culture, Occupation, Craft, Language, Aging, etc.) with cross-table links
