Implement D&D 5e death-save state machine and cleanup combat ordering

- Add status-driven death-save model:
  - status: conscious | dying | stable | dead
  - deathSaveSuccesses/deathSaveFailures as display counters
  - remove old death-save fields as source of truth
- Add death-save actions:
  - success, fail, nat1, nat20
  - stabilize participant
  - revive dead participant to 0 HP, stable, unconscious
- Apply 5e HP transition rules:
  - characters and NPCs at 0 HP become dying
  - stable/dying participants gain unconscious condition
  - healing clears death saves and returns conscious
  - massive damage kills
  - non-NPC monsters at 0 HP become dead and inactive
- Split NPCs from monsters with type="npc":
  - NPCs use death saves like characters
  - NPCs remain DM-controlled/monster-colored in UI
  - new NPCs no longer persist isNpc flag
- Keep dead PCs/NPCs in encounter and initiative until DM removes or deactivates
- Allow DM active/inactive toggle for dead participants
- Hide inactive participants from player display
- Improve DM and player death-state UI:
  - show Dying/Dead/Unconscious states consistently
  - add revive button for dead participants
  - distinguish dead visual from inactive visual in DM view
- Fix initiative drag/reorder behavior:
  - downward drag now changes order instead of no-op
  - paused combat can reorder across current turn pointer
  - turnOrderIds stay synced to participants order
- Persist campaign collapse state in localStorage
- Update death-save docs and encounter builder docs
- Add/expand tests for:
  - death saves and HP transitions
  - dead/active/inactive behavior
  - NPC death-save behavior
  - player display visibility
  - drag reorder semantics
  - logging expectations

Tests:
- npm run test:all
- app: 94 passed
- shared: 158 passed, 5 skipped
- server: 32 passed

+# Death Saves 5e - Implementation Plan
+
+TDD required. Tests first, implementation after.
+
+## Gap Analysis
+
+**Current:**
+- ✅ Separate success/fail counters (deathSaves, deathFails)
+- ✅ 3 success → stable, 3 fail → dead
+- ✅ UI shows ✓/✕ buttons, status badges
+
+**Missing (from DEATH_SAVES.md):**
+- ❌ Nat 20: 1 HP + conscious, reset counters
+- ❌ Nat 1: 2 failures
+- ❌ Damage at 0 HP → add failures (normal=1, crit=2)
+- ❌ Massive damage: damage >= currentHp + maxHp → instant dead
+- ❌ Stabilize manual action
+- ❌ Healing resets counters
+- ❌ Damage breaks stable → back to dying
+
+**Test Gap:**
+- turn.deathsave.test.js: basic counters only
+- turn.combat.test.js: single deathSave call, no coverage
+- Combat.scenario.test.js: basic fail/death flow
+- No nat20, nat1, damage-at-0, massive damage, stabilize, healing integration
+
+## Phase 1: Extend Tests (TDD)
+
+### File: `shared/tests/turn.deathsave.nat20.test.js`
+
+Test cases:
+- Nat20 → hp=1, deathSaves=0, deathFails=0, isDying=false, isStable=false, status="conscious"
+- Nat20 overrides existing saves/fails
+- Nat20 log entry correct
+
+### File: `shared/tests/turn.deathsave.nat1.test.js`
+
+Test cases:
+- Nat1 → deathFails += 2
+- Nat1 triggers instant death (3 fails total)
+- Nat1 log entry correct
+
+### File: `shared/tests/turn.deathsave.damage.test.js`
+
+Test cases:
+- Damage at 0 HP → deathFails += 1
+- Crit damage at 0 HP → deathFails += 2
+- Mixed: save success + damage → independent tracking works
+- Damage log includes "while dying"
+
+### File: `shared/tests/turn.deathsave.massive.test.js`
+
+Test cases:
+- Damage >= currentHp + maxHp → instant dead
+- Bypasses death saves entirely
+- Log entry shows "massive damage"
+
+### File: `shared/tests/turn.deathsave.stabilize.test.js`
+
+Test cases:
+- Stabilize → hp=0, isStable=true, isDying=false, counters=0
+- Stabilize from dying state
+- Stabilize log entry correct
+
+### File: `shared/tests/turn.deathsave.heal.test.js`
+
+Test cases:
+- Healing at 0 HP → reset counters, isDying=false, isStable=false
+- Healing at stable → same reset
+- Healing log includes "cleared death saves"
+
+### File: `shared/tests/turn.deathsave.stable.test.js`
+
+Test cases:
+- Damage to stable → isStable=false, isDying=true, counters reset
+- Stable takes damage → fresh death save loop
+
+### File: `shared/tests/turn.deathsave.undo.test.js`
+
+Test cases:
+- Undo deathSave restores previous state
+- Undo nat20 restores counters
+- Undo damage at 0 HP restores fail count
+- Undo stabilize restores dying state
+
+## Phase 2: Combat Test Integration
+
+### Update `shared/tests/turn.combat.test.js`
+
+Add phases:
+- Nat20 phase: roll nat20, verify 1 HP + conscious
+- Nat1 phase: roll nat1, verify 2 failures
+- Damage-at-zero phase: normal damage + crit damage at 0 HP
+- Massive damage phase: instant death bypass
+- Stabilize phase: stabilize dying character
+- Healing-reset phase: heal at 0 HP, verify counters reset
+- Assert death save state at each phase
+
+### Update `src/tests/Combat.scenario.test.js`
+
+Add action functions:
+- deathSaveActionNat20(name)
+- deathSaveActionNat1(name)
+- stabilizeAction(name)
+- applyDamageAtZero(name, amount, isCrit)
+- applyMassiveDamage(name)
+- healingResetAction(name, amount)
+
+Add scenario phases:
+- Round 10-20: nat20/nat1 scenarios
+- Round 30-40: damage-at-zero scenarios (normal + crit)
+- Round 50-60: stabilize scenarios
+- Round 70-80: massive damage scenarios
+- Round 90-100: healing-reset scenarios
+- Verify log entries include all death save types
+
+### Update `scripts/combat.js`
+
+Verify death save events:
+- Check death_save events in log
+- Verify nat20, nat1, damage_at_zero, massive_damage log types
+- Verify stabilize events
+- Verify healing_reset events
+
+## Phase 3: Extend `deathSave` Function
+
+Add roll result parameter:
+```ts
+async function deathSave(encounter, participantId, type, n, rollResult, ctx) {
+  // rollResult: number (1-20) or null for manual input
+}
+```
+
+Handle nat20:
+```ts
+if (rollResult === 20) {
+  updates.hp = 1;
+  updates.deathSaves = 0;
+  updates.deathFails = 0;
+  updates.isDying = false;
+  updates.isStable = false;
+  status = 'conscious';
+}
+```
+
+Handle nat1:
+```ts
+if (rollResult === 1) {
+  const currentFails = participant.deathFails || 0;
+  updates.deathFails = Math.min(3, currentFails + 2);
+  // Check for death...
+}
+```
+
+## Phase 4: Extend `applyHpChange` Function
+
+Add damage-at-zero logic:
+```ts
+if (changeType === 'damage' && participant.currentHp === 0) {
+  const failuresToAdd = isCritical ? 2 : 1;
+  const currentFails = participant.deathFails || 0;
+  updates.deathFails = Math.min(3, currentFails + failuresToAdd);
+  updates.isStable = false;
+  // Check for death...
+}
+```
+
+Add massive damage rule:
+```ts
+if (changeType === 'damage' && damage >= participant.currentHp + participant.maxHp) {
+  updates.hp = 0;
+  updates.isDying = true;
+  updates.deathSaves = 0;
+  updates.deathFails = 3;
+  updates.isStable = false;
+}
+```
+
+Add healing reset logic:
+```ts
+if (changeType === 'heal' && (participant.currentHp === 0 || participant.isStable || participant.isDying)) {
+  updates.deathSaves = 0;
+  updates.deathFails = 0;
+  updates.isDying = false;
+  updates.isStable = false;
+}
+```
+
+## Phase 5: New `stabilizeParticipant` Function
+
+```ts
+async function stabilizeParticipant(encounter, participantId, ctx) {
+  // hp=0, isStable=true, isDying=false, counters=0
+  // Log: "Stabilized"
+}
+```
+
+## Phase 6: UI Extensions
+
+### Phase 6a: Roll Result Modal
+
+Add roll result input:
+- Modal when clicking death save button
+- Input: d20 result (1-20) or "manual"
+- Auto-detect nat20/nat1
+
+### Phase 6b: Nat1/Nat20/Stabilize Buttons
+
+Death save row layout:
+```
+[Saves:  □ □ □]  [Fails:  □ □ □]
+[Nat1] [Nat20] [Stabilize]
+```
+
+**Nat1 button:**
+- Red icon (AlertTriangle)
+- Click → deathSave(participantId, 'fail', null, 1, ctx)
+- Adds 2 failures immediately
+- Log: "Nat 1! [name] takes 2 death save failures"
+- Disable if deathFails >= 2 (would cause death anyway)
+
+**Nat20 button:**
+- Gold icon (Zap)
+- Click → deathSave(participantId, 'success', null, 20, ctx)
+- Sets hp=1, resets counters, conscious
+- Log: "Nat 20! [name] restored to 1 HP, conscious"
+
+**Stabilize button:**
+- Emerald icon (HeartPulse)
+- Only show when dying (hp=0, !isStable, !dead)
+- Click → stabilizeParticipant(participantId, ctx)
+- Sets isStable=true, counters=0
+- Log: "[name] stabilized at 0 HP"
+- Hide if already isStable
+
+**Conditional visibility:**
+- All buttons: only when hp === 0 && !dead
+- Stabilize: hide if already isStable
+- Nat1: disable if deathFails >= 2
+
+### Phase 6c: Crit Checkbox for Damage
+
+Add crit checkbox:
+- For damage at 0 HP
+- Pass crit to applyHpChange
+- UI: checkbox "Critical hit?"
+
+### Phase 6d: Enhanced Log Messages
+
+- Nat20: "Nat 20! [name] restored to 1 HP, conscious"
+- Nat1: "Nat 1! [name] takes 2 death save failures"
+- Damage at 0: "[name] takes [n] damage while dying"
+- Massive damage: "Massive damage! [name] instantly killed"
+- Stabilize: "[name] stabilized at 0 HP"
+- Healing reset: "[name] healed to [n] HP, death saves cleared"
+
+## Phase 7: Integration Tests
+
+File: `shared/tests/turn.deathsave.flow.test.js`
+
+Test full scenarios:
+- Dying → nat20 → conscious → take damage → dying
+- Dying → nat1 → 2 fails → another fail → dead
+- Dying → stabilize → damage → dying again
+- Massive damage bypasses all
+- Healing resets mid-death-save loop
+
+## Execution Order
+
+1. Phase 1: Write all test files (fail expected)
+2. Phase 2: Update combat tests (fail expected)
+3. Phase 3: Extend deathSave, run tests
+4. Phase 4: Extend applyHpChange, run tests
+5. Phase 5: Add stabilizeParticipant, run tests
+6. Phase 6a: Roll result modal
+7. Phase 6b: Nat1/Nat20/Stabilize buttons
+8. Phase 6c: Crit checkbox
+9. Phase 6d: Enhanced log messages
+10. Phase 7: Integration tests
+11. Manual testing: full scenarios in dev server
+
+## Risk Notes
+
+- Roll result input: optional field (DM may not want to input every roll)
+- Crit detection: manual checkbox (no way to auto-detect)
+- Massive damage: optional rule (some tables ignore)
+- Backward compat: existing API must still work with null rollResult
+- Nat1/Nat20/Stabilize buttons: DM-optional, not required to use

+# Death Saves (D&D 5e)
+
+Concept and rule structure for the death-save state machine. Reference for how
+combat tracking should behave at 0 HP. This is the 5e death-save loop, not a
+code spec.
+
+## Scope: tracker tracks, DM decides
+
+This tracker is not a virtual tabletop. It does not roll dice or interpret the
+table. The DM rolls at the table, decides what happened, and feeds the result
+into the tracker through the UI. The tracker records the result and applies the
+automatic pieces.
+
+- DM does: rolls the d20, determines crits vs normal hits, declares damage
+  amounts, decides when to stabilize or heal.
+- Tracker does: increments success/failure counters on DM input, resolves the
+  terminal states (3 successes → stable, 3 failures → dead), resets counters on
+  heal or stabilize, records HP changes.
+
+The transitions below describe the rules the tracker must honor once the DM
+hands it a result. The DM is the source of truth for what happened; the tracker
+is the source of truth for what state that produces.
+
+## State
+
+A character or NPC at 0 HP enters a death-save loop. Track per death-save participant:
+
+```ts
+deathSaveSuccesses: 0 | 1 | 2 | 3
+deathSaveFailures:  0 | 1 | 2 | 3
+status:             "conscious" | "dying" | "stable" | "dead"
+hp:                 number
+```
+
+## Transitions
+
+**Drop to 0 HP** (damage, character/NPC):
+- If damage >= currentHp + maxHp → outright dead (massive damage). Equivalently: after reducing currentHp to 0, overflow damage >= maxHp.
+- Otherwise → `status = "dying"`, counters reset to 0.
+
+**Drop to 0 HP** (monster):
+- Non-NPC monsters do not use death saves.
+- `status = "dead"`, counters reset, `isActive = false`.
+
+**Death save** (d20 roll on a dying character/NPC turn):
+
+```ts
+if roll === 1:          failures += 2      // natural 1 = two failures
+else if roll === 20:    hp = 1; successes = 0; failures = 0; status = "conscious"  // nat 20 = 1 HP, conscious
+else if roll >= 10:     successes += 1
+else:                   failures += 1
+```
+
+Then resolve immediately on the click/action that reaches 3:
+
+```ts
+if failures >= 3:  status = "dead"; successes = 0; failures = 0
+if successes >= 3: status = "stable"; successes = 0; failures = 0
+```
+
+The UI must transition immediately. A third failure shows Dead state, not three
+active failure boxes. A third success shows Stable state, not three active
+success boxes.
+
+**Damage while dying** (at 0 HP):
+
+```ts
+failures += isCriticalHit ? 2 : 1
+if failures >= 3: status = "dead"
+```
+
+Attacks from within 5 ft against an unconscious creature are auto-crits, so
+melee vs a dying character/NPC adds 2 failures.
+
+**Healing while dying or stable**:
+
+Any +HP received while `dying` or `stable` makes the character/NPC conscious.
+This usually comes from magic, or from the stable-state time-delayed recovery
+(1 HP after 1d4 hours, if the DM chooses to track it here).
+
+```ts
+hp = max(1, hp + amount)
+successes = 0
+failures = 0
+status = "conscious"
+```
+
+Any HP regained from `dying` or `stable` clears all counters and ends the
+death-save loop. This does **not** apply to `dead`; dead requires revive flow,
+revival magic, or DM state override, not normal healing.
+
+**Stabilize** (manual action, not a save):
+
+```ts
+hp = 0
+successes = 0
+failures = 0
+status = "stable"
+```
+
+## Stable state
+
+- Stays at 0 HP, unconscious, no longer makes death saves.
+- 3 successes = **stable (unconscious)**, NOT conscious. NOT 1 HP.
+  1 HP only comes from a natural 20 or healing.
+- Taking any damage ends stable → back to `dying` (counters reset, then damage
+  applies its failure per "damage while dying").
+
+## Tool-specific initiative behavior
+
+Death is a combat state, not an automatic removal action.
+
+When a character or NPC becomes `dead`:
+- Do **not** remove them from initiative.
+- Do **not** automatically deactivate them.
+- Do **not** remove them from the encounter participants list.
+- Leave them in turn order. Other table/tool events may still matter on that
+  initiative count.
+- DM may manually mark them inactive or remove them.
+
+When a non-NPC monster becomes `dead`:
+- Set `isActive = false` automatically.
+- Keep it in the encounter participants list until DM removes it.
+- Player display hides it because inactive participants are hidden.
+
+## Invariants
+
+- `status === "dying"` ⟺ hp === 0 AND no terminal flag.
+- `status === "stable"` ⟹ hp === 0, unconscious, counters 0.
+- `status === "dead"` ⟹ hp === 0, no further saves, counters 0.
+- `status === "dead"` ⟹ participant remains in initiative and participants until DM removes them.
+- `status === "dead"` does not itself mean inactive; monster death sets inactive as a separate rule.
+- Normal +HP applies to `dying` or `stable`, not `dead`; dead requires revive, revival, or DM override.
+- Successes and failures tracked **independently**. 2 fail + 3 success = stable.
+  Counters do not need to be consecutive.
+- A roll of 10+ is a success. 9 or lower is a failure.

+# Log System Redesign Plan
+
+**Status:** DRAFT — not started
+**Branch:** `feat-turn-writes-logs`
+**Goal:** Lean mutation deltas. Kill bloated payload/undo duplication.
+
+## Problem
+
+Current events = 10-16KB each. `add_participant` row = 16KB to say "Fighter added, init 22." Root cause: full participant roster stored 3x (payload + undo_payload.updates + undo_payload.redo).
+
+DB: 2486 docs, most bloated. Replay trace 1.6-5.5MB for ~250 steps.
+
+Old log (pre-refactor) = message string + small undo object. Proven worked for undo/redo + viewer. Just wanted MORE STRUCTURE, not MORE DATA. Overbuilt instead.
+
+## Intention
+
+Each event = mutation delta + lean snapshot. Structured for filter/group/analyzer. No roster arrays.
+
+### Canonical lean event shape
+
+```js
+{
+  id, ts, type,                    // identity + filter key
+  message,                         // human text (viewer displays)
+  encounterId, encounterName,      // which encounter
+  participantId, participantName,  // who (nullable: pause/nextTurn have none)
+  // type-specific scalar delta (one of these clusters per type):
+  //   add:        { init, maxHp, type: 'character'|'monster' }
+  //   remove:     { dead: bool }
+  //   damage/heal:{ amount }
+  //   condition:  { condition }
+  //   toggleActive:{ revive: bool }
+  //   reorder:    { draggedId, targetId }
+  //   update:     { changedFields: ['notes', ...] }
+  //   nextTurn:   (none — snapshot carries new round/pointer)
+  //   pause/resume/start/end: (none)
+  snapshot: {                      // lean, ALREADY GOOD — keep as-is
+    round, currentTurnParticipantId, turnOrderIds, activeIds
+  },
+  undo: <type-specific inverse, id-based>  // minimal
+}
+```
+
+### Undo inverses (id-based, minimal)
+
+| type | undo |
+|------|------|
+| add_participant | `{ participantId }` → removeParticipant by id |
+| remove_participant | full participant obj (must restore — only place full obj needed) |
+| damage | `{ amount: -amount }` or heal back |
+| heal | `{ amount: -amount }` or damage back |
+| condition | `{ condition }` (toggle is its own inverse) |
+| toggleActive | `{ revive: !revive }` |
+| reorder | `{ draggedId, targetId }` (swap back) |
+| update | `{ changedFields: [...], oldValues: {...} }` |
+| nextTurn | `{ currentTurnParticipantId, round }` from snapshot delta |
+| pause/resume | toggle |
+| start/end | full prior scalar state |
+
+**No `redo` field.** Redo = re-apply forward delta from event itself.
+
+**No `undo_payload` wrapper.** Just `undo` object.
+
+## 4 Consumers
+
+1. **Viewer** — shows `message` + `type` + `participantName` + `undone` flag. Legacy logs (no type) display message only.
+2. **Undo/redo** — apply `undo` inverse by id. Id-based, minimal.
+3. **Replay** — turn.js funcs write own lean events. Trust func return. NO read-back. JSONL trace = lean snapshots + types.
+4. **Analyzer** — reads `snapshot` sequence + `type`. Reconstructs roster from event stream (add/remove by id). NO payload arrays needed.
+
+## Legacy Support
+
+- **Viewer:** yes — show old message-only logs, no type parse
+- **Undo:** no — old logs unundoable (acceptable, sit inert)
+- **Analyzer:** best-effort — snapshot may be absent on legacy → skip invariant check for that run
+
+## Why Lean
+
+- `add_participant` 16KB → ~150 bytes
+- Replay trace 5.5MB → ~250KB
+- Undo still works (proven old log did same)
+- Analyzer unaffected (uses snapshot+type, not payload)
+
+## Migration Plan
+
+### Phase 1: Redesign event writers (shared/turn.js)
+
+- [ ] Rewrite `buildEntry()` to produce lean shape (delta fields per type)
+- [ ] Rewrite `commit()` — no patch storage, write lean event
+- [ ] Per-func: compute minimal delta + inverse from enc before/after
+- [ ] Drop `payload`, `undo_payload`, `undo_payload.redo`
+
+### Phase 2: Update undo executor
+
+- [ ] Find undo consumer (App.js `applyUndo` or similar)
+- [ ] Switch to id-based inverse application
+- [ ] Handle each type's undo shape
+- [ ] Drop `transactionalUndo` full-patch path if exists
+
+### Phase 3: Update replay trace
+
+- [ ] `replay-combat.js` callStep: trust return, snapshot only (no read-back)
+- [ ] Trace = `{step, ts, type, pre:leanSnap, post:leanSnap}` — no participant arrays
+
+### Phase 4: Update analyzer
+
+- [ ] `analyze-turns.js` already uses snapshot+type only — verify no payload dep
+- [ ] Reconstruct roster from event stream for skip/double-act checks (id-level)
+
+### Phase 5: Legacy compat
+
+- [ ] `logEvent.js normalizeEvent` — lift legacy into lean shape (type='legacy', message only)
+- [ ] Viewer handles legacy gracefully
+- [ ] Download = lean events only (legacy excluded or message-only)
+
+### Phase 6: Cleanup
+
+- [ ] Delete old bloated docs from DB? Or leave (inert, viewer reads message)?
+- [ ] Verify build CI=true passes
+- [ ] Verify analyzer clean on fresh replay
+- [ ] Verify undo works on new events
+
+## NOT in scope
+
+- Fixing 5 pre-existing initiative bugs (logged in TODO.md, separate)
+- Changing snapshot shape (already lean)
+- Changing viewer UI (just data source)
+
+## Open Questions
+
+- Undo for `remove_participant`: must restore full obj (only place full obj needed). Acceptable?
+- Should legacy logs be deleted from DB or left inert?
+- Download format: lean JSON array (no legacy) — confirm
