+# Architectural Decisions
+
+## [2026-02-20] Task 2: TxUpdatedInterval
+
+### Decision 1: Separate TxUpdatedInterval from MeterValues
+
+- **Context**: Both send periodic messages during transactions
+- **Decision**: Keep completely separate timers (`transactionSetInterval` vs `transactionTxUpdatedSetInterval`)
+- **Rationale**:
+ - Different intervals (MeterValueSampleInterval vs TxUpdatedInterval)
+ - Different message types (MeterValues vs TransactionEvent)
+ - Different trigger reasons (Periodic vs MeterValuePeriodic)
+ - OCPP spec treats them as independent features
+
+### Decision 2: Export Strategy for OCPP Types
+
+- **Context**: Circular dependency issues with OCPP20ServiceUtils import
+- **Decision**: Export from `ocpp/index.ts` as single source of truth
+- **Rationale**: Prevents circular imports, maintains clean module boundaries
+
+### Decision 3: Interval Validation Approach
+
+- **Context**: Need to validate TxUpdatedInterval from variable manager
+- **Decision**: Default to 30s if variable missing/invalid, no error thrown
+- **Rationale**: Graceful degradation, aligns with OCPP "SHOULD" requirement (not "SHALL")
--- /dev/null
+# Known Issues & Gotchas
+
+## [2026-02-20] Task 2: TxUpdatedInterval
+
+### Issue 1: Import Path for OCPP20ServiceUtils
+
+- **Problem**: Direct import caused circular dependency errors
+- **Solution**: Export via `ocpp/index.ts` centralized exports
+- **Files affected**: ChargingStation.ts, ocpp/index.ts
+
+### Issue 2: Timer Safety with Large Intervals
+
+- **Problem**: JavaScript setTimeout/setInterval has MAX_SAFE_INTEGER limit
+- **Solution**: Use `clampToSafeTimerValue()` utility (max 2147483647ms ~= 24.8 days)
+- **Reference**: src/utils/Utils.ts lines 388-396
+
+### Issue 3: TransactionEvent During Transaction
+
+- **Context**: sendTransactionEvent needs active transaction check
+- **Validation**: Check `transactionStarted === true` AND `transactionId != null` before sending
+- **Reason**: Timer may fire after transaction ends if stop is delayed
+
+## Patterns to Avoid
+
+- ❌ Hardcoded intervals (use variable manager)
+- ❌ Missing OCPP version guards (breaks 1.6 compatibility)
+- ❌ Unhandled promise rejections in setInterval callbacks
+- ❌ Forgetting to clear timers on transaction end (memory leak)
--- /dev/null
+# Learnings & Conventions
+
+## [2026-02-20] Task 2: TxUpdatedInterval Implementation
+
+### Patterns Established
+
+- **Timer management**: Use `clampToSafeTimerValue()` wrapper for all setInterval calls
+- **Variable retrieval**: Use `OCPP20VariableManager.getVariables()` with component/variable lookup
+- **Lifecycle hooks**: START at RequestStartTransaction, STOP before transaction cleanup
+- **ConnectorStatus fields**: Store timer references in connector status for cleanup
+- **Error handling**: Catch promise rejections in setInterval callbacks with logger.error
+
+### Code Conventions
+
+- Import enums from `src/charging-station/ocpp/index.ts` (centralized exports)
+- Follow existing MeterValues pattern for periodic message sending
+- Validate OCPP version at method entry (`if (ocppVersion !== VERSION_20) return`)
+- Check connector null and interval validity before starting timers
+- Prevent duplicate timers (check if timer already exists)
+
+### File Structure
+
+- ChargingStation.ts: Public start/stop methods
+- OCPP20IncomingRequestService.ts: Private helper + START lifecycle
+- OCPP20ServiceUtils.ts: STOP lifecycle hook
+- ConnectorStatus.ts: Timer field storage
+- ocpp/index.ts: Centralized type exports
--- /dev/null
+# Unresolved Problems
+
+## Task 3: Offline TransactionEvent Queueing (PENDING)
+
+### Key Questions to Answer
+
+1. Where does WebSocket offline detection happen?
+2. How does existing messageQueue pattern work?
+3. How is seqNo currently tracked and incremented?
+4. Where should queue flush logic hook into reconnection flow?
+5. What happens to in-flight TransactionEvent messages during disconnect?
+
+### Research Needed
+
+- Explore WebSocket lifecycle hooks (disconnect/connect events)
+- Find existing queue implementation patterns
+- Understand seqNo persistence across offline periods
+- Identify transaction context preservation during offline
+- Review OCPP 2.0.1 requirements for offline message ordering
+
+### Potential Risks
+
+- seqNo gaps during offline period
+- Message loss if queue not persisted
+- Out-of-order delivery on reconnection
+- Race conditions during reconnection flood

+## Authorization Testing Modes
+
+The server supports configurable authorization behavior for testing OCPP 2.0 authentication scenarios:
+
+### Command Line Options
+
+```shell
+poetry run python server.py --auth-mode <MODE> [--whitelist TOKEN1 TOKEN2 ...] [--blacklist TOKEN1 TOKEN2 ...] [--offline]
+```
+
+**Auth Options:**
+
+- `--auth-mode <MODE>`: Authorization mode (default: `normal`)
+ - `normal` - Accept all authorization requests (default)
+ - `whitelist` - Only accept tokens in the whitelist
+ - `blacklist` - Block tokens in the blacklist, accept all others
+ - `rate_limit` - Reject all requests with `NotAtThisTime` (simulates rate limiting)
+ - `offline` - Not used directly (use `--offline` flag instead)
+- `--whitelist TOKEN1 TOKEN2 ...`: Space-separated list of authorized tokens (default: `valid_token test_token authorized_user`)
+- `--blacklist TOKEN1 TOKEN2 ...`: Space-separated list of blocked tokens (default: `blocked_token invalid_user`)
+- `--offline`: Simulate network failure (raises ConnectionError on Authorize requests)
+
+### Examples
+
+**Whitelist mode** (only accept specific tokens):
+
+```shell
+poetry run python server.py --auth-mode whitelist --whitelist valid_token test_token
+```
+
+**Blacklist mode** (block specific tokens):
+
+```shell
+poetry run python server.py --auth-mode blacklist --blacklist blocked_token invalid_user
+```
+
+**Offline mode** (simulate network failure):
+
+```shell
+poetry run python server.py --offline
+```
+
+**Rate limit simulation**:
+
+```shell
+poetry run python server.py --auth-mode rate_limit
+```
+
