"""Tool-layer secrets — user-configured tokens & API keys (#103).
The connected-source (Gitea / GitHub) and keyed web-search (Tavily, Brave,
SerpAPI, Exa) tools read their credentials through this module instead of
``os.environ`` directly. The value comes from the store the user edits in the
configuration page (``data/api_keys.json`` — the same file the AI provider
keys use) first, then falls back to the environment (Infisical-injected in
production). Nothing is ever hard-coded and no tool result carries a secret
(the registry redacts payloads).
Allowed names are whitelisted: only the variables below can be stored or
deleted from the configuration page.
