+# Data Model: Combatant Row Declutter
+
+**Feature**: 019-combatant-row-declutter
+**Date**: 2026-03-06
+
+## No Data Model Changes
+
+This feature is a purely visual/interaction refactor within the web adapter layer. No domain entities, application state, or persistence formats are affected.
+
+### Existing entities (unchanged)
+
+- **Combatant**: `id`, `name`, `initiative`, `maxHp`, `currentHp`, `ac`, `conditions`, `isConcentrating` — no fields added, removed, or modified.
+
+### Existing callbacks (unchanged)
+
+- `onAdjustHp(id: CombatantId, delta: number)` — same signature, now triggered from popover instead of inline QuickHpInput.
+- `onSetAc(id: CombatantId, value: number | undefined)` — same signature, now triggered from click-to-edit instead of always-visible input.
+
+### UI State (component-local only)
+
+New component-local state introduced in the HP popover (not persisted):
+- **popoverOpen**: boolean — whether the HP adjustment popover is visible.
+- **inputValue**: string — the draft delta value in the popover input.
+
+New component-local state in the AC click-to-edit (not persisted):
+- **editing**: boolean — whether the inline AC edit input is visible.
+- **draft**: string — the draft AC value being edited.
+
+These follow the same patterns as existing component-local state (`EditableName.editing`, `ConditionPicker` open state).

+# Implementation Plan: Combatant Row Declutter
+
+**Branch**: `019-combatant-row-declutter` | **Date**: 2026-03-06 | **Spec**: [spec.md](./spec.md)
+**Input**: Feature specification from `/specs/019-combatant-row-declutter/spec.md`
+
+## Summary
+
+Replace always-visible HP adjustment controls (QuickHpInput with delta input + Sword/Heart buttons) and AC input field with compact, on-demand interaction patterns. HP becomes a clickable value that opens a popover for damage/healing. AC becomes a static shield+number display with click-to-edit inline editing. This is purely a web adapter (UI) change — domain and application layers are untouched.
+
+## Technical Context
+
+**Language/Version**: TypeScript 5.8 (strict mode, verbatimModuleSyntax)
+**Primary Dependencies**: React 19, Vite 6, Tailwind CSS v4, Lucide React (icons)
+**Storage**: N/A (no storage changes — existing localStorage persistence unchanged)
+**Testing**: Vitest (unit tests for pure functions; UI behavior verified manually)
+**Target Platform**: Desktop and tablet-width browsers
+**Project Type**: Web application (monorepo with domain/application/web layers)
+**Performance Goals**: N/A (no performance-sensitive changes)
+**Constraints**: Keyboard-accessible, no domain/application layer modifications
+**Scale/Scope**: 1 component modified (CombatantRow), 1 component removed (QuickHpInput), 1 new component (HpAdjustPopover). AC and Max HP click-to-edit are implemented inline within CombatantRow (no separate component files)
+
+## Constitution Check
+

+
+| Principle | Status | Notes |

+| IV. Clarification-First | PASS | Feature description was fully specified, no ambiguities |
+| V. Escalation Gates | PASS | All changes within spec scope |
+| VI. MVP Baseline Language | PASS | No permanent bans introduced |
+| VII. No Gameplay Rules | PASS | No gameplay mechanics in plan |
+

+    └── input.tsx            # existing (used by popover and AC inline edit)
+```
+
+**Structure Decision**: All changes are confined to `apps/web/src/components/`. No new directories needed. The existing monorepo structure (domain → application → web) is preserved. No contracts directory needed since this is an internal UI refactor with no external interfaces.

+# Quickstart: Combatant Row Declutter
+
+**Feature**: 019-combatant-row-declutter
+**Date**: 2026-03-06
+
+## What This Feature Does
+
+Replaces always-visible HP adjustment controls and AC input with compact, on-demand interactions:
+1. **HP**: Click the current HP number to open a small popover for damage/healing.
+2. **AC**: Click the shield+number display to edit AC inline.
+
+## Key Files
+
+| File | Role |
+|------|------|
+| `apps/web/src/components/combatant-row.tsx` | Main combatant row — modified to use new patterns |
+| `apps/web/src/components/hp-adjust-popover.tsx` | New popover component for HP adjustment |
+| `apps/web/src/components/quick-hp-input.tsx` | Removed — replaced by HP popover |
+
+## How It Works
+
+### HP Adjustment Flow
+1. Current HP displays as a clickable, color-coded number (amber=bloodied, red=unconscious)
+2. Click opens a popover with auto-focused numeric input + Damage/Heal buttons
+3. Enter = apply damage (negative delta), Shift+Enter = apply healing (positive delta)
+4. Popover dismisses on action, Escape, or click-outside
+
+### AC Edit Flow
+1. AC displays as static text: shield icon + number (or just shield if unset)
+2. Click opens inline input (same pattern as editable name)
+3. Enter/blur commits, Escape cancels
+
+## Development
+
+```bash
+pnpm --filter web dev     # Start dev server
+pnpm check                # Run full quality gate before committing
+```
+
+## Constraints
+
+- Domain and application layers are unchanged
+- `onAdjustHp` and `onSetAc` callback signatures unchanged

+# Research: Combatant Row Declutter
+
+**Feature**: 019-combatant-row-declutter
+**Date**: 2026-03-06
+
+## R1: Popover Dismissal Pattern
+
+**Decision**: Use a click-outside listener with ref-based boundary detection, consistent with the existing ConditionPicker component pattern.
+
+**Rationale**: The codebase already uses this pattern in `condition-picker.tsx` / `condition-tags.tsx` where clicking outside the picker closes it. Reusing the same approach maintains consistency and avoids introducing new dependencies (e.g., a popover library). The popover will use `useEffect` with a document-level click handler that checks if the click target is outside the popover ref.
+
+**Alternatives considered**:
+- Headless UI library (Radix Popover, Floating UI): Adds a dependency for a simple use case. Rejected — the project has no headless UI library and introducing one for a single popover is over-engineering.
+- HTML `<dialog>` / `popover` attribute: Native browser support is good, but the `popover` attribute doesn't provide the positioning control needed (anchored to the HP value). Rejected for insufficient positioning semantics.
+
+## R2: Click-to-Edit Pattern for AC
+
+**Decision**: Reuse the exact same pattern as the existing `EditableName` component — toggle between static display and input on click, commit on Enter/blur, cancel on Escape.
+
+**Rationale**: `EditableName` in `combatant-row.tsx` already implements this exact interaction pattern. The AC click-to-edit can follow the same state machine (editing boolean, draft state, commit/cancel callbacks). This ensures behavioral consistency across the row.
+
+**Alternatives considered**:
+- Popover (same as HP): AC editing is simpler (just set a value, no damage/heal distinction), so a popover adds unnecessary complexity. Rejected.
+- Double-click to edit: Less discoverable than single-click. Rejected — the existing name edit uses single-click.
+
+## R3: HP Popover Positioning
+
+**Decision**: Position the popover directly below (or above if near viewport bottom) the current HP value using simple CSS absolute/relative positioning.
+
+**Rationale**: The popover only needs to appear near the trigger element. The combatant row is a simple list layout — no complex scrolling containers or overflow clipping that would require a positioning library. Simple CSS positioning (relative parent + absolute child) is sufficient.
+
+**Alternatives considered**:
+- Floating UI / Popper.js: Provides advanced positioning with flip/shift. Overkill for this use case since the encounter list is a straightforward vertical layout. Rejected.
+
+## R4: Keyboard Shortcuts in Popover
+
+**Decision**: Handle Enter (damage) and Shift+Enter (heal) via `onKeyDown` on the popover's input element. Escape handled at the same level to close the popover.
+
+**Rationale**: This matches the existing QuickHpInput pattern where Enter applies damage. Adding Shift+Enter for healing is a natural modifier key extension. The input captures all keyboard events, so no global listeners are needed.
+
+**Alternatives considered**:
+- Separate keyboard shortcut system: Unnecessary complexity for two shortcuts scoped to a single input. Rejected.

+# Feature Specification: Combatant Row Declutter
+
+**Feature Branch**: `019-combatant-row-declutter`
+**Created**: 2026-03-06
+**Status**: Draft
+**Input**: User description: "Declutter combatant row with click-to-edit patterns — replace always-visible HP adjustment and AC inputs with compact, on-demand interactions"
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - HP Click-to-Adjust Popover (Priority: P1)
+
+As a DM running combat, I want to click on a combatant's current HP value to open a small adjustment popover, so the combatant row is visually clean and I can still quickly apply damage or healing when needed.
+
+**Why this priority**: HP adjustment is the most frequent mid-combat interaction and the QuickHpInput with its Sword/Heart buttons is the biggest source of visual clutter. Replacing it with an on-demand popover delivers the largest declutter impact.
+
+**Independent Test**: Can be fully tested by clicking a combatant's current HP, entering a number, and pressing Enter (damage) or Shift+Enter (heal), then verifying the HP updates correctly and the popover dismisses.
+
+**Acceptance Scenarios**:
+
+1. **Given** a combatant with max HP set (e.g., 30/30), **When** I look at the row, **Then** I see only the current HP number and max HP — no delta input or action buttons are visible.
+2. **Given** a combatant with max HP set, **When** I click the current HP number, **Then** a small popover opens containing an auto-focused numeric input and Damage/Heal buttons.
+3. **Given** the HP popover is open with a valid number entered, **When** I press Enter, **Then** damage is applied (negative delta), the popover closes, and the HP value updates.
+4. **Given** the HP popover is open with a valid number entered, **When** I press Shift+Enter, **Then** healing is applied (positive delta), the popover closes, and the HP value updates.
+5. **Given** the HP popover is open with a valid number entered, **When** I click the Damage button, **Then** damage is applied and the popover closes.
+6. **Given** the HP popover is open with a valid number entered, **When** I click the Heal button, **Then** healing is applied and the popover closes.
+7. **Given** the HP popover is open, **When** I press Escape, **Then** the popover closes without applying any change.
+8. **Given** the HP popover is open, **When** I click outside the popover, **Then** the popover closes without applying any change.
+9. **Given** a combatant whose HP is at or below half (bloodied), **When** I view the row, **Then** the current HP number displays in the bloodied color (amber).
+10. **Given** a combatant whose HP is at 0 (unconscious), **When** I view the row, **Then** the current HP number displays in the unconscious color (red).
+11. **Given** a combatant with no max HP set, **When** I view the row, **Then** the HP area shows only the max HP input — no clickable current HP value.
+
+---
+
+### User Story 2 - AC Click-to-Edit (Priority: P2)
+
+As a DM, I want the AC field to appear as a compact static display (shield icon + number) that I can click to edit inline, so the row is less cluttered while AC remains easy to set or change.
+
+**Why this priority**: AC is set less frequently than HP is adjusted, so converting it to a click-to-edit pattern provides good declutter value with lower interaction frequency impact.
+
+**Independent Test**: Can be fully tested by clicking the AC display, editing the value, and confirming via Enter or blur, then verifying the AC updates correctly.
+
+**Acceptance Scenarios**:
+
+1. **Given** a combatant with AC set (e.g., 15), **When** I view the row, **Then** I see a shield icon followed by the number "15" as static text — not an input field.
+2. **Given** a combatant with no AC set, **When** I view the row, **Then** I see just the shield icon (no number) as a clickable element.
+3. **Given** a combatant's AC display, **When** I click it, **Then** an inline input appears with the current AC value pre-filled and selected.
+4. **Given** the AC inline edit is active, **When** I type a new value and press Enter, **Then** the AC updates and the display reverts to static mode.
+5. **Given** the AC inline edit is active, **When** I click away (blur), **Then** the AC updates and the display reverts to static mode.
+6. **Given** the AC inline edit is active, **When** I press Escape, **Then** the edit is cancelled, the original value is preserved, and the display reverts to static mode.
+7. **Given** the AC inline edit is active, **When** I clear the field and press Enter, **Then** the AC is unset and the display shows just the shield icon.
+
+---
+
+### User Story 3 - Max HP Click-to-Edit (Priority: P2)
+
+As a DM, I want the max HP field to appear as a compact static display that I can click to edit inline, so the row is consistent with the AC click-to-edit pattern and further reduces visual clutter.
+
+**Why this priority**: Max HP is set once during encounter setup and rarely changed. Converting it to click-to-edit applies the same declutter pattern as AC for consistency.
+
+**Independent Test**: Can be fully tested by clicking the max HP display, editing the value, and confirming via Enter or blur, then verifying the max HP updates correctly.
+
+**Acceptance Scenarios**:
+
+1. **Given** a combatant with max HP set (e.g., 30), **When** I view the row, **Then** I see the max HP as static text — not an input field.
+2. **Given** a combatant with no max HP set, **When** I view the row, **Then** I see a clickable placeholder to set max HP.
+3. **Given** a combatant's max HP display, **When** I click it, **Then** an inline input appears with the current max HP value pre-filled and selected.
+4. **Given** the max HP inline edit is active, **When** I type a new value and press Enter, **Then** the max HP updates and the display reverts to static mode.
+5. **Given** the max HP inline edit is active, **When** I click away (blur), **Then** the max HP updates and the display reverts to static mode.
+6. **Given** the max HP inline edit is active, **When** I press Escape, **Then** the edit is cancelled and the display reverts to static mode.
+7. **Given** the max HP inline edit is active, **When** I clear the field and press Enter, **Then** the max HP is unset and HP tracking is removed.
+
+---
+
+### Edge Cases
+
+- What happens when the user enters non-numeric or negative values in the HP popover? The input only accepts positive integers; non-numeric input is ignored.
+- What happens when the user enters 0 in the HP popover? Zero is not a valid delta and the action buttons remain disabled.
+- What happens when the HP popover is open and the user tabs away? The popover closes without applying changes (same as blur/click-outside).
+- What happens on tablet-width screens? The popover and inline edit must remain accessible and not overflow or clip at viewports ≥ 768px wide (Tailwind `md` breakpoint).
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: System MUST replace the always-visible QuickHpInput (delta input + Sword/Heart buttons) with a clickable current HP display that opens a popover on interaction.
+- **FR-002**: The HP popover MUST contain a single auto-focused numeric input and two action buttons (Damage and Heal).
+- **FR-003**: The HP popover MUST support keyboard shortcuts: Enter for damage, Shift+Enter for heal, Escape to dismiss.
+- **FR-004**: The HP popover MUST dismiss automatically after an action is applied, on Escape, or when clicking outside.
+- **FR-005**: The current HP display MUST retain color-coded status indicators (amber for bloodied, red for unconscious) when the popover is closed.
+- **FR-006**: System MUST replace the always-visible AC input field with a static display (shield icon + number).
+- **FR-007**: Clicking the AC static display MUST open an inline edit input that commits on Enter or blur and cancels on Escape.
+- **FR-008**: The max HP MUST display as compact static text with click-to-edit, consistent with the AC pattern.
+- **FR-009**: The existing callback signatures (`onAdjustHp`, `onSetAc`) MUST remain unchanged — this is a UI-only change.
+- **FR-010**: All interactive elements MUST remain keyboard-accessible (focusable, operable via keyboard).
+- **FR-011**: The HP popover input MUST only accept positive integers as valid delta values.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: The combatant row displays fewer always-visible interactive controls — specifically, 3 fewer visible elements (delta input, Damage button, Heal button) per combatant when HP is set.
+- **SC-002**: The AC field takes up less horizontal space in its default state compared to an always-visible input field.
+- **SC-003**: Users can apply damage or healing in 3 or fewer interactions (click HP, type number, press Enter/Shift+Enter).
+- **SC-004**: Users can edit AC in 3 or fewer interactions (click AC, type number, press Enter).
+- **SC-005**: All HP and AC interactions remain fully operable using only a keyboard.
+
+## Assumptions
+
+- The popover is a lightweight component positioned near the current HP value — not a full modal dialog.
+- The HP popover uses a simple overlay/click-outside pattern, consistent with how the condition picker already works in the app.
+- The AC click-to-edit follows the exact same pattern as the existing editable name component (click to edit, Enter/blur to commit, Escape to cancel).
+- Domain and application layers require zero changes — all modifications are confined to the web adapter (React components).
+- The CurrentHpInput component is either removed or repurposed as a static display + popover trigger, rather than being an always-visible input.

+# Tasks: Combatant Row Declutter
+
+**Input**: Design documents from `/specs/019-combatant-row-declutter/`
+**Prerequisites**: plan.md (required), spec.md (required for user stories), research.md, data-model.md, quickstart.md
+
+**Tests**: Not explicitly requested in the feature specification. Test tasks are omitted.
+
+**Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story.
+
+## Format: `[ID] [P?] [Story] Description`
+
+- **[P]**: Can run in parallel (different files, no dependencies)
+- **[Story]**: Which user story this task belongs to (e.g., US1, US2)
+- Include exact file paths in descriptions
+
+---
+
+## Phase 1: Setup (Shared Infrastructure)
+
+**Purpose**: No new project setup needed — this feature modifies existing components only. Phase skipped.
+
+---
+
+## Phase 2: Foundational (Blocking Prerequisites)
+
+**Purpose**: No foundational/blocking work required. Both user stories modify independent components within the same file and can proceed directly.
+
+---
+
+## Phase 3: User Story 1 - HP Click-to-Adjust Popover (Priority: P1) MVP
+
+**Goal**: Replace the always-visible QuickHpInput (delta input + Sword/Heart buttons) with a clickable current HP display that opens a popover for damage/healing.
+
+**Independent Test**: Click a combatant's current HP number, enter a value, press Enter (damage) or Shift+Enter (heal), verify HP updates and popover dismisses. Verify bloodied/unconscious color coding on the static HP display.
+
+### Implementation for User Story 1
+
+- [x] T001 [US1] Create HpAdjustPopover component in `apps/web/src/components/hp-adjust-popover.tsx` — popover with auto-focused numeric input, Damage button (red/Sword icon), and Heal button (green/Heart icon). Input accepts positive integers only. Enter applies damage (negative delta), Shift+Enter applies healing (positive delta). Popover dismisses on action, Escape, or click-outside (use ref-based click-outside listener per research.md R1).
+- [x] T002 [US1] Replace CurrentHpInput in `apps/web/src/components/combatant-row.tsx` with a clickable static HP display — render current HP as a `<button>` element with color-coded text (amber for bloodied, red for unconscious via `deriveHpStatus`). On click, open the HpAdjustPopover. Wire popover's onAdjustHp to existing `onAdjustHp` callback with unchanged signature.
+- [x] T003 [US1] Remove QuickHpInput usage from `apps/web/src/components/combatant-row.tsx` — delete the `<QuickHpInput>` render and its import. The HP section should now show: clickable current HP / max HP input (always-visible).
+- [x] T004 [US1] Delete `apps/web/src/components/quick-hp-input.tsx` — component is fully replaced by HpAdjustPopover.
+- [x] T005 [US1] Run `pnpm check` to verify no lint, type, format, test, or unused-code errors after HP popover changes.
+
+**Checkpoint**: HP adjustment works via click-to-adjust popover. No always-visible delta input or Sword/Heart buttons. Color-coded HP status preserved.
+
+---
+
+## Phase 4: User Story 2 - AC Click-to-Edit (Priority: P2)
+
+**Goal**: Replace the always-visible AC input field with a static display (shield icon + number) that becomes an inline edit on click.
+
+**Independent Test**: View a combatant row and verify AC shows as shield+number text (not an input). Click it, edit the value, press Enter — verify AC updates. Press Escape — verify edit cancels. Clear and commit — verify AC unsets.
+
+### Implementation for User Story 2
+
+- [x] T006 [US2] Refactor AcInput in `apps/web/src/components/combatant-row.tsx` to a click-to-edit pattern — default state renders shield icon + AC number as a `<button>` (or just shield icon if AC is unset). On click, switch to an inline `<Input>` with the current value pre-filled and selected. Commit on Enter/blur, cancel on Escape. Follow the same state pattern as the existing `EditableName` component (editing boolean, draft state, commit/cancel callbacks).
+- [x] T007 [US2] Run `pnpm check` to verify no lint, type, format, test, or unused-code errors after AC click-to-edit changes.
+
+**Checkpoint**: AC displays as compact static text. Click-to-edit works with Enter/blur commit and Escape cancel.
+
+---
+
+## Phase 4b: User Story 3 - Max HP Click-to-Edit (Priority: P2)
+
+**Goal**: Replace the always-visible Max HP input field with a static display that becomes an inline edit on click, consistent with the AC click-to-edit pattern.
+
+**Independent Test**: View a combatant row and verify Max HP shows as static text (not an input). Click it, edit the value, press Enter — verify Max HP updates. Press Escape — verify edit cancels. Clear and commit — verify Max HP unsets.
+
+### Implementation for User Story 3
+
+- [x] T010 [US3] Refactor MaxHpInput in `apps/web/src/components/combatant-row.tsx` to a click-to-edit pattern — default state renders max HP number as a `<button>` (or placeholder text "Max" if unset). On click, switch to an inline `<Input>` with the current value pre-filled and selected. Commit on Enter/blur, cancel on Escape. Follow the same state pattern as `AcDisplay` and `EditableName`.
+- [x] T011 [US3] Run `pnpm check` to verify no lint, type, format, test, or unused-code errors after Max HP click-to-edit changes.
+
+**Checkpoint**: Max HP displays as compact static text. Click-to-edit works with Enter/blur commit and Escape cancel.
+
+---
+
+## Phase 5: Polish & Cross-Cutting Concerns
+
+**Purpose**: Final cleanup and grid layout adjustment after both stories are complete.
+
+- [x] T008 Adjust combatant row grid layout in `apps/web/src/components/combatant-row.tsx` — update the `grid-cols-[...]` template to account for reduced HP section width (no more QuickHpInput) and compact AC display. Verify alignment on desktop and tablet-width viewports. Verify keyboard accessibility: HP display and AC display must be focusable via Tab, operable via Enter, and dismissable via Escape (FR-010).
+- [x] T009 Run final `pnpm check` to verify the complete feature passes all quality gates.
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **User Story 1 (Phase 3)**: No prerequisites — can start immediately
+- **User Story 2 (Phase 4)**: No dependency on US1 — can start in parallel
+- **Polish (Phase 5)**: Depends on both US1 and US2 being complete
+
+### User Story Dependencies
+
+- **User Story 1 (P1)**: Independent — modifies HP section of combatant row
+- **User Story 2 (P2)**: Independent — modifies AC section of combatant row
+
+### Within Each User Story
+
+- HpAdjustPopover component (T001) must be created before integrating into combatant row (T002)
+- QuickHpInput removal (T003, T004) must follow popover integration (T002)
+- AC refactor (T006) is a single self-contained change
+
+### Parallel Opportunities
+
+- US1 (T001-T005) and US2 (T006-T007) can run in parallel since they modify different sections of the combatant row
+- Within US1: T001 (new component) can be written before T002-T004 (integration + cleanup)
+
+---
+
+## Parallel Example: User Stories 1 & 2
+
+```bash
+# These two stories can run in parallel (different component sections):
+# Developer A: User Story 1 — HP popover
+Task: T001 "Create HpAdjustPopover component"
+Task: T002 "Replace CurrentHpInput with clickable display + popover"
+Task: T003 "Remove QuickHpInput usage from combatant row"
+Task: T004 "Delete quick-hp-input.tsx"
+Task: T005 "Run pnpm check"
+
+# Developer B: User Story 2 — AC click-to-edit
+Task: T006 "Refactor AcInput to click-to-edit pattern"
+Task: T007 "Run pnpm check"
+```
+
+---
+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 3: User Story 1 (HP popover) — T001 through T005
+2. **STOP and VALIDATE**: Test HP popover independently
+3. This alone delivers the biggest declutter win (removes 3 always-visible controls per row)
+
+### Incremental Delivery
+
+1. Add User Story 1 → Test independently → Commit (MVP!)
+2. Add User Story 2 → Test independently → Commit
+3. Polish phase → Final grid adjustments → Commit
+4. Each story adds declutter value without breaking previous work
+
+---
+
+## Notes
+
+- [P] tasks = different files, no dependencies
+- [Story] label maps task to specific user story for traceability
+- Domain and application layers are untouched — all changes in `apps/web/src/components/`
+- Callback signatures (`onAdjustHp`, `onSetAc`) remain unchanged
+- Commit after each completed user story
