+# Phase 36 Plan 02: Voice Schema Foundation Summary
+
+**One-liner:** voiceMode enum field added to createMessageSchema and ChatMessage, plus nexus-settings extended with voiceMode (default "text"), telegramToken, piperBinaryPath, and whisperBinaryPath.
+
+## Completed Tasks
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Extend shared validators and types with voiceMode field | 390034c7 | packages/shared/src/validators/chat.ts, packages/shared/src/types/chat.ts, server/src/__tests__/36-voice-schema.test.ts |
+| 2 | Extend nexus-settings schema with voiceMode and telegramToken | 044e3dad | server/src/services/nexus-settings.ts, server/src/__tests__/36-voice-schema.test.ts |
+
+## What Was Built
+
+### packages/shared/src/validators/chat.ts
+
+Added `VOICE_MODES` constant, `VoiceMode` type, and optional `voiceMode` field to `createMessageSchema`:
+
+```typescript
+export const VOICE_MODES = ["text", "voice_input", "full_voice"] as const;
+export type VoiceMode = (typeof VOICE_MODES)[number];
+
+// In createMessageSchema:
+voiceMode: z.enum(VOICE_MODES).optional(),
+```
+
+### packages/shared/src/types/chat.ts
+
+Added optional `voiceMode` field to `ChatMessage` interface:
+
+```typescript
+voiceMode?: "text" | "voice_input" | "full_voice" | null;
+```
+
+### server/src/services/nexus-settings.ts
+
+Extended `nexusSettingsSchema` with four new fields, exported the schema for testing, updated fallback logic:
+
+```typescript
+export const nexusSettingsSchema = z.object({
+  mode: z.enum(NEXUS_MODES).default("both"),
+  voiceEnabled: z.boolean().default(false),
+  voiceMode: z.enum(VOICE_MODES).default("text"),
+  telegramToken: z.string().optional(),
+  piperBinaryPath: z.string().optional(),
+  whisperBinaryPath: z.string().optional(),
+});
+```
+
+### server/src/__tests__/36-voice-schema.test.ts
+
+11 tests covering:
+- createMessageSchema voiceMode enum validation (6 tests)
+- nexusSettingsSchema voiceMode defaults and telegramToken (5 tests)
+
+## Verification
+
+All verification checks pass:
+
+- `pnpm --filter @paperclipai/server test --run` exits 0 for 36-voice-schema.test.ts (11/11 tests)
+- `grep "voiceMode" packages/shared/src/validators/chat.ts` shows the field
+- `grep "voiceMode" packages/shared/src/types/chat.ts` shows the field
+- `grep "voiceMode" server/src/services/nexus-settings.ts` shows the field
+- `grep "telegramToken" server/src/services/nexus-settings.ts` shows the field

+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Known Stubs

+None — this plan adds schema/type foundations only. No UI rendering or data flow is introduced.
