Add Stripe payment integration across the project:
- Add @stripe/stripe-js dependency
- Configure Stripe environment variables (secret key, publishable key, webhook secret) for dev, local, and production environments
- Add Product/Price IDs for monthly, quarterly, and annual subscription tiers
- Extend subscription plan data with voiceMinutesPerDay quotas (30/45/60 minutes per tier)
- Update .gitignore to exclude implementation_plan.md
- Remove unused `quotaWarningThreshold` and `warningThreshold` getter from `GuestChatQuota` DTO
- Apply get-or-init pattern in `ChatStorage.getGuestDailyChatQuota` and `getGuestTotalQuota`: when no existing value, initialize with DTO defaults (`threshold` = max per day, `totalQuotaDefault`) and return the seeded data
- Fall back to original `null` result if initialization write fails
- Consolidate logging strategy: drop per-actor trace logs in `chat-machine.ts`, keep business-decision logs in 3 assign actions, move all actor ENTRY/API/DONE chains to `chat-machine.actors.ts` and helper load logs to `chat-machine.helpers.ts`
Update implementation_plan.md with a detailed refactor plan that splits
`chatInitActor` into two independent actors (`loadQuotaActor` +
`loadHistoryActor`) and redesigns the history loading flow to follow
local → network → save semantics so the UI sees local data first,
then network data.
Key changes outlined in the plan:
- Add new events: `ChatQuotaLoaded`, `ChatHistoryLocalLoaded`,
`ChatHistoryNetworkLoaded`, `ChatHistorySyncDone`
- Remove dead-code `ChatInit` event
- Extend `ChatState` with `quotaLoaded` and `historyLoaded` flags
- Use an `always` barrier in `guestSession.initializing` and
`userSession.initializing` so both tasks must complete before
transitioning to `ready`
- Guest init runs `loadQuota` + `loadHistory` in parallel; non-guest
init runs `chatWebSocket` + `loadHistory` as independent tasks
Also adds `implementation_plan` to .gitignore.
- Move src/data/{api,dto,schemas} directories to src/data/services/*
- Update all relative imports across the codebase to reference new paths
- Use CSS color tokens for splash button gradient in splash-button.module.css
- Add responsive sizes attribute to splash background image
- Add JSDoc documentation to splash-background component referencing original Dart implementation
Reorganize the data layer by separating DTOs (Data Transfer Objects) from
Zod validation schemas into distinct directory structures. Previously,
all model types were imported from a single `@/data/models` barrel
file, mixing request/response classes with validation schemas.
Changes:
- Update API files (auth, chat, metrics, user) to import DTOs from
specific paths under `@/data/dto/*` instead of the models barrel
- Move user schema to `@/data/schemas/user/user` for type-only imports
- Create dedicated Zod schema files under `@/data/schemas/*` for
auth and chat domain models (e.g., AppleLoginRequestSchema,
SendMessageRequestSchema, SyncMessageSchema, SttDataSchema)
- Improve discoverability and tree-shaking by co-locating schemas
with their respective domain areas
This is a non-functional refactor that lays the groundwork for
clearer separation between transport-layer types and runtime
validation.
