📋 Decision Context

Question:

What security hardening changes were implemented in Phase 5 of embeddable-bridge?

Task: Phase 5 Security Hardening & Production Readiness

🎯 Decision Made

Chosen:

7 comprehensive security tasks: message type whitelist, log sanitization, wildcard origin removal, instance ID validation, rate limiting enforcement, payload validators, offline support integration

Options Considered:

• No alternatives documented

💭 Reasoning

Phase 5 addresses all security findings from the browser-based testing in Session 73.8. Task 5.1 adds a VALID_MESSAGE_TYPES whitelist to reject unknown messages. Task 5.2 sanitizes sensitive data (tokens, passwords) from debug logs. Task 5.3 removes wildcard '*' from postMessage targetOrigin after handshake. Task 5.4 validates instanceId format. Task 5.5 adds enforceRateLimit() for block/throttle/warn actions. Task 5.6 adds validateAuthPayload() and validateDragPayload() for runtime type checking. Task 5.7 integrates OfflineService, OfflineIndicatorComponent, and service worker build configuration.
