## 5. Database/Schema Alignment

### Status: N/A

No DB-layer changes were introduced in this session.

### Issues Found

N/A -- no DB-layer changes.

***

## 6. Success Criteria

From `spec.md`:

### Functional Requirements

* [x] Battlefield hero tokens are native buttons with stable accessible names, `aria-pressed`, pointer activation, keyboard activation, and visible selected state.
* [x] Selecting via battlefield, roster, and hero detail remains synchronized through existing store state.
* [x] Clicking empty board space clears selected hero state without token click propagation accidentally clearing the new selection.
* [x] Active, awaiting input, verifying, error, spawning, dismissed, selected, and idle states remain visually distinct through labels, rings, badges, glow, or static marks.
* [x] Failed background and hero image loads keep the board and tokens visibly recoverable.
* [x] Missing, non-finite, and out-of-range hero coordinates map to safe, clamped board positions.
* [x] Achievement bursts stay bounded, nonblocking, timer-cleaned, and reduced-motion compatible.

### Testing Requirements

* [x] Component tests cover battlefield selection, accessible names, selected state, empty-board clear, image fallbacks, state labels, and reduced-motion static treatment.
* [x] Helper tests cover coordinate clamping, dynamic world limits, missing coordinates, non-finite coordinates, and edge label placement.
* [x] Celebration tests cover new unlock diffing, concurrent cap behavior, timer cleanup, deterministic tone output, and reduced-motion expectations.
* [x] Focused battlefield tests and `npm --workspace apps/web run typecheck` pass before validation.

### Quality Gates

* [x] All files ASCII-encoded.
* [x] Unix LF line endings.
* [x] Code follows project conventions.

| Testing        | PASS   | Focused tests cover the session contract.                                 |

### Convention Violations

None.

## 9. Behavioral Quality Spot-Check

### Status: PASS

**Checklist applied**: Yes **Files spot-checked**: `apps/web/src/components/battlefield/Battlefield.tsx`, `apps/web/src/components/battlefield/achievementCelebration.ts`, `apps/web/src/lib/battlefield2d.ts`, `apps/web/tests/Battlefield.test.tsx`, `apps/web/tests/BattlefieldInteraction.test.tsx`

| Category           | Status | File                                                  | Details                                                                                                        |
| ------------------ | ------ | ----------------------------------------------------- | -------------------------------------------------------------------------------------------------------------- |
| Trust boundaries   | PASS   | `apps/web/src/components/battlefield/Battlefield.tsx` | Native button selection and empty-board clearing stay within the local store boundary.                         |
| Resource cleanup   | PASS   | `apps/web/src/components/battlefield/Battlefield.tsx` | Celebration timers are cleared on unmount and when bursts expire.                                              |
| Mutation safety    | PASS   | `apps/web/src/components/battlefield/Battlefield.tsx` | Selection toggles and achievement burst capping are bounded and idempotent enough for the current UI contract. |
| Failure paths      | PASS   | `apps/web/src/components/battlefield/Battlefield.tsx` | Background and hero-art failures fall back to readable UI states.                                              |
| Contract alignment | PASS   | `apps/web/src/lib/battlefield2d.ts`                   | Position mapping and label placement remain aligned with the board contract.                                   |

### Violations Found

None.

### Fixes Applied During Validation

None.

## Validation Result

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase02-session04-battlefield-state-and-interaction-polish/validation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
