📋 Decision Context

Question:

Is CORS actually blocking port 6200 requests as the Testing Director reported?

Task: Verify and fix CORS blocking on port 6200

🎯 Decision Made

Chosen:

No — cors.factory.ts already allows ALL localhost origins via isLocalhostOrigin() (line 154), which runs before the ALLOWED_ORIGINS check. Updated .env.local ALLOWED_ORIGINS for documentation clarity only.

Options Considered:

• No alternatives documented

💭 Reasoning

The Testing Director's analysis was based on reading .env.local and seeing port 6200 missing from ALLOWED_ORIGINS. However, cors.factory.ts has a isLocalhostOrigin() check at line 154 that unconditionally allows all localhost origins BEFORE the explicit allowed list is checked. The CORS bug is a non-issue with the current code — the .env.local was misleading but not functionally broken. Updated it anyway for clarity.
