Ahmed Allam	08df05db61	fix(preflight): skip unused credentials for subscription models, check dedupe credentials too	2026-10-04 01:48:35 +03:00
Ahmed Allam	4ca15a6e60	style: drop docstrings from the header-value check	2026-10-04 01:48:35 +03:00
Ahmed Allam	539960d953	fix(preflight): name a non-ASCII character in the API key instead of raising UnicodeEncodeError ... httpx encodes header values as ASCII, so a smart quote, non-breaking space or byte-order mark pasted into LLM_API_KEY (or LLM_EXTRA_HEADERS) surfaced as a bare UnicodeEncodeError from inside the client, wrapped in ModelConnectionError. The preflight now checks these settings first and fails with the setting name, the code point, its Unicode name and its position. Nothing is trimmed or rewritten and the key itself is never printed.	2026-10-04 01:48:35 +03:00
