Finite State Machines (FSM & SubFSM) + +TeslaSync models many domain processes as state machines — vehicle lifecycle, charging sessions, +trips, export jobs, and notifications. The current codebase has **scattered, inconsistent, and +duplicated state transition logic** — the single biggest source of bugs. This section establishes +a unified FSM framework that all domain processes must follow. + +### 8.1 Why a Unified FSM Framework + +| Problem in Current Code | How the FSM Framework Fixes It | +|-------------------------|-------------------------------| +| State transitions scattered across handlers, services, workers | All transitions defined in one place per aggregate (the FSM definition) | +| Invalid transitions silently ignored or produce corrupt data | Transitions validated before execution; invalid transitions return errors | +| Duplicated guard/condition checks in multiple code paths | Guards are registered once per transition, enforced by the engine | +| Side effects (notifications, API calls) tightly coupled to transitions | Side effects are registered as hooks (OnEnter, OnExit, OnTransition), decoupled from the FSM core | +| No audit trail of state changes | Every transition is logged, traced, and optionally persisted to a history table | +| SubFSMs (nested states) handled with ad-hoc `if` chains | First-class SubFSM support with proper lifecycle management | + +### 8.2 Core FSM Types + +All FSM types live in `internal/domain/fsm/`. This package has **zero external dependencies** — +it is pure domain logic. + +```go +// internal/domain/fsm/types.go + +// State represents a named state in the machine. +type State string + +// Event represents a trigger that may cause a state transition. +type Event string + +// Guard is a predicate that must return true for a transition to proceed. +// Guards receive the transition context and can inspect the entity being transitioned. +type Guard[T any] func(ctx context.Context, entity T, event Event) (bool, error) + +// Action is a side-effect executed during a transition. +// Actions are NOT allowed to change the FSM state — they react to transitions. +type Action[T any] func(ctx context.Context, entity T, transition Transition) error + +// Transition describes a single allowed state change. +type Transition struct { + From State + Event Event + To State +} + +// HookType defines when a hook fires relative to a transition. +type HookType int + +const ( + BeforeTransition HookType = iota // Fires before state change (can abort via error) + AfterTransition // Fires after state change (cannot abort) + OnEnterState // Fires when entering a state (any transition into it) + OnExitState // Fires when leaving a state (any transition out of it) +) +``` + +### 8.3 FSM Definition — Declarative Transition Tables + +**Rule: Every FSM is defined as a declarative transition table.

Refactoring Playbook + +This section provides step-by-step procedures for common refactoring tasks during the cleanup effort. + +### 16.1 Before You Refactor: The Checklist + +- [ ] **Identify the smell:** Name the specific problem (duplicate code, god function, leaking abstraction, etc.) +- [ ] **Write a characterization test:** Before changing anything, write a test that captures the current behavior — even if the behavior is buggy, you need to know what changes. +- [ ] **Check the blast radius:** Which other packages/components import or depend on the code you're changing? +- [ ] **Plan the PR sequence:** If the refactor touches > 400 lines, plan how to split it into incremental PRs. +- [ ] **Communicate:** Post a brief RFC in the PR description or team channel if the change affects shared interfaces. + +### 16.2 Extracting Duplicate Code + +**Step 1: Find all instances.** Use `grep -rn` or IDE "Find Usages" to locate every copy. + +**Step 2: Identify the canonical version.** Which copy is most complete / correct / tested? + +**Step 3: Extract to the right layer:** + +| Duplicate Is | Extract To | +|-------------|-----------| +| Business logic | `internal/domain/{aggregate}/` | +| Use-case orchestration | `internal/app/{service}/` | +| Database query pattern | `internal/adapter/postgres/` | +| HTTP helper (request parsing, response writing) | `internal/handler/middleware/` or `internal/platform/httputil/` | +| React component | `components/ui/` or `components/feedback/` | +| React data fetching | `api/hooks/` | +| TypeScript utility | `lib/` | + +**Step 4: Replace all call sites.** Import the extracted function/component. Delete the old copies. + +**Step 5: Run tests.** All existing tests must pass. Add tests for the extracted code if none existed. + +### 16.3 Breaking Up God Functions + +**Symptom:** A function that is > 80 lines, has cyclomatic complexity > 15, or mixes multiple concerns. + +**Procedure:** + +1. **Outline:** Read the function and write comments marking logical sections. +2. **Extract methods:** Each section becomes a private method with a descriptive name. +3. **Test each method:** Write unit tests for extracted methods. +4. **Simplify the parent:** The original function becomes a coordinator that calls the extracted methods. + +```go +// BEFORE — 150-line function mixing validation, DB, API, and notification logic +func (s *Service) ProcessChargingSession(ctx context.Context, raw RawSession) error { + // 30 lines of validation... + // 40 lines of DB operations... + // 30 lines of Tesla API calls... + // 25 lines of cost calculation... + // 25 lines of notification logic... +} + +// AFTER — coordinator function, each step is testable +func (s *Service) ProcessChargingSession(ctx context.Context, raw RawSession) error { + session, err := s.validateAndParse(raw) + if err != nil { + return fmt.Errorf("validate: %w", err) + } + if err := s.enrichWithTeslaData(ctx, session); err != nil { + return fmt.Errorf("enrich: %w", err) + } + if err := s.calculateCost(ctx, session); err != nil { + return fmt.Errorf("calculate cost: %w", err) + } + if err := s.repo.Save(ctx, session); err != nil { + return fmt.Errorf("save: %w", err) + } + s.notifyAsync(ctx, session) // fire-and-forget, errors logged internally + return nil +} +``` + +### 16.4 Migrating Scattered SQL to Repository Pattern + +**Current state (bad):** SQL queries embedded in handlers, services, and random utility functions. + +**Target state:** All SQL lives in `internal/adapter/postgres/`, behind port interfaces. + +**Procedure:** + +1. **Audit:** Run `grep -rn "SELECT\|INSERT\|UPDATE\|DELETE" internal/` to find all SQL. +2. **Group by entity:** Cluster queries by the table/aggregate they operate on. +3. **Create repository interface:** Define the port in `internal/port/repository/`. +4. **Create implementation:** Move queries to `internal/adapter/postgres/queries/` constants, implement the repository. +5. **Update callers:** Services now depend on the repository interface instead of `*pgxpool.Pool`. +6. **Remove direct pool access:** Services should not have access to the raw pool (except for transaction management). + +### 16.5 Consolidating Frontend API Calls + +**Current state (bad):** `fetch()` calls scattered across components, inconsistent error handling, no caching strategy. + +**Target state:** All API calls go through TanStack Query hooks in `api/hooks/`. + +**Procedure:** + +1. **Audit:** `grep -rn "fetch(\|axios\|apiClient" web/src/` to find all API calls. +2. **Group by resource:** `/vehicles`, `/trips`, `/charging`, etc. +3. **Create query key factory:** Centralized key definitions prevent cache key conflicts. +4. **Create hooks:** One file per resource in `api/hooks/`. +5. **Replace all direct calls:** Components use hooks, never `fetch()` directly. +6. **Add MSW handlers:** For each endpoint, create a mock in `test/mocks/handlers/`. + +### 16.6 De-duplicating React Components + +**Procedure:** + +1. **Inventory:** List all components across `features/*/components/` and `components/`. +2. **Identify overlaps:** Find components with similar purpose (e.g., multiple loading spinners, card layouts, data tables). +3. **Choose the best version:** Pick the most complete/accessible implementation. +4. **Generalize:** Add props to handle the differences between the copies. +5. **Promote to `components/`:** Move the canonical version to `components/ui/` or `components/feedback/`. +6. **Replace & delete:** Update all import paths. Delete the old copies. +7. **Add Storybook stories (optional):** Document the shared component visually. + +### 16.7 Migrating Ad-Hoc State Logic to FSM Engine + +**Current state (bad):** State transitions implemented via `if/else` and `switch` chains in handlers, +services, and workers. Guard conditions duplicated. No audit trail. Race conditions on concurrent events. + +**Target state:** All state transitions go through the FSM engine with declarative transition tables, +guards, hooks, and persisted history. + +**Procedure:** + +1. **Inventory:** Search for state-related logic: `grep -rn "state\|status\|fsm\|transition" internal/`. + List every place where an entity's state is changed. +2. **Map the state machine:** Draw the states and transitions for each entity on paper or a diagram. + Identify which transitions have guards (preconditions) and which have side effects. +3. **Define the FSM in domain layer:** Create `internal/domain/{entity}/fsm.go` with typed state/event + constants and a declarative `NewXxxFSM()` function. +4. **Identify SubFSM candidates:** If any state has its own internal lifecycle (sub-states, sub-transitions), + extract it as a SubFSM in `internal/domain/{entity}/sub_fsm.go`. +5. **Extract guards:** Move precondition checks into named guard functions in `internal/domain/{entity}/guards.go`. +6. **Extract hooks:** Move side effects (notifications, telemetry, calculations) into named hook functions + in `internal/app/{service}/hooks.go`. +7. **Wire in application service:** Create a `HandleXxxEvent()` method that: loads entity with row lock → + fires FSM event → persists new state → records transition history — all in one TX. +8. **Replace all call sites:** Every `entity.State = "new_state"` becomes `fsmEngine.Fire(ctx, entity, event)`. +9. **Add DB columns:** Add `fsm_state` (and `sub_fsm_state` if SubFSM) columns via migration. + Backfill existing rows with the correct state values. +10. **Add to FSM Catalog:** Update §8.11 with the new FSM entry. +11. **Write tests:** Cover all valid transitions, key invalid transitions, guard rejections, and SubFSM lifecycle. + +--- + +## 17. Anti-Patterns Catalog + +This catalog documents specific patterns found in the current codebase that must be eliminated during refactoring. Reference these by name in PR reviews. + +### 17.1 Backend Anti-Patterns + +| ID | Anti-Pattern | Problem | Fix | +|----|-------------|---------|-----| +| B1 | **Scattered SQL** | SQL queries in handlers, services, utils — impossible to audit, easy to duplicate | Move all SQL to `adapter/postgres/`. Expose via repository interface. | +| B2 | **God Function** | Functions > 100 lines doing validation + DB + API + notifications | Extract into focused, testable functions. One function = one job. | +| B3 | **Swallowed Errors** | `if err != nil { log.Error() }` with no return — caller thinks success | Always return errors. Let the caller decide what to do. | +| B4 | **Global State** | Package-level `var db *pgxpool.Pool` accessed directly | Inject via constructor. No global mutable state. | +| B5 | **Missing Context** | Functions that do I/O without `context.Context` | Add `ctx context.Context` as first parameter. | +| B6 | **Stringly-Typed** | Magic strings like `"charging"`, `"idle"`, `"driving"` scattered everywhere | Define `type VehicleState string` constants in domain package. | +| B7 | **Config Scatter** | `os.Getenv("DB_HOST")` in random packages | Single `config.MustLoad()` at startup. Pass config down. | +| B8 | **Copy-Paste Handlers** | HTTP handlers that duplicate JSON parsing, validation, error response logic | Extract shared `DecodeAndValidate`, `Respond`, `RespondError` helpers. | +| B9 | **Bare Goroutines** | `go func() { ... }()` without error handling or panic recovery | Use `errgroup.Group` or wrap with panic recovery. | +| B10 | **No Timeouts** | External API calls with no context timeout | Wrap every outbound call with `context.WithTimeout`. | +| B11 | **Ad-Hoc State Machines** | State transitions via `if/else`/`switch` chains scattered in handlers and services | Use the FSM engine (`internal/domain/fsm/`). Define transitions declaratively. | +| B12 | **Implicit State Transitions** | State changes happen as side effects in unrelated functions, not clearly named transition logic | Route ALL state changes through `fsmEngine.Fire()`. Wrap in a transaction. | +| B13 | **Missing FSM Guards** | Invalid transitions silently succeed, producing corrupt data (e.g., charging session completed with 0 kWh) | Add guards to the FSM definition. Guards enforce preconditions before transitions. | +| B14 | **SubFSM State Leak** | SubFSM state persists after the parent exits the owning state, causing stale sub-state on re-entry | Configure `ResetOnExit: true` on SubFSM registration. | +| B15 | **Unaudited Transitions** | No record of how an entity reached its current state — impossible to debug | Persist every transition to `fsm_transitions` table inside the same TX. | + +### 17.2 Frontend Anti-Patterns + +| ID | Anti-Pattern | Problem | Fix | +|----|-------------|---------|-----| +| F1 | **Direct fetch()** | `fetch('/api/...')` in components — no caching, no error handling, no auth | Use TanStack Query hooks via `api/hooks/`. | +| F2 | **Prop Drilling** | Passing data through 5+ component levels | Use TanStack Query (server state) or React Context (client state). | +| F3 | **useEffect for Data** | `useEffect(() => { fetch(...).then(setData) }, [])` | Use `useQuery` — handles loading, error, caching, refetch. | +| F4 | **Duplicated Components** | Multiple loading spinners, error displays, card layouts | Consolidate into `components/ui/` and `components/feedback/`. | +| F5 | **any Types** | `data: any` — disables TypeScript's entire value proposition | Use proper types. `unknown` + narrowing when type is uncertain. | +| F6 | **Hardcoded Strings** | User-facing text in JSX without i18next | Use `useTranslation()` and translation keys. | +| F7 | **Inline Styles** | `style={{ marginTop: 16, color: '#333' }}` | Use Tailwind utility classes. | +| F8 | **Index as Key** | `{items.map((item, i) => )}` with dynamic lists | Use stable unique IDs as keys. | +| F9 | **Giant Components** | Single component file > 200 lines | Extract sub-components and custom hooks. | +| F10 | **State Duplication** | `useState` mirroring server data already in TanStack Query cache | Remove local state, use query data directly. | +| F11 | **Raw HTML in Features** | Feature component creates `
