This is the proper architectural fix for #685. The previous commit was a
bandaid that prevented unnecessary .env writes. This commit addresses the
root cause: dual-source-of-truth for API tokens (.env vs api_tokens.json).
Changes:
1. Startup Migration (config.go:896-951):
- When loading config, if API_TOKEN/API_TOKENS exist in .env but not in
api_tokens.json, automatically migrate them
- Migrated tokens are named "Migrated from .env (prefix)" for clarity
- Logs a deprecation warning: API_TOKEN/API_TOKENS in .env are deprecated
- Leaves .env untouched (safe for existing deployments)
2. Config Watcher Changes (watcher.go:338-424):
- Only load tokens from .env if api_tokens.json is EMPTY
- Once api_tokens.json has records, it becomes the authoritative source
- .env changes no longer trigger token overwrites when api_tokens.json exists
- Logs debug message when ignoring env tokens
Result:
- Existing deployments: env tokens automatically migrated to api_tokens.json
- UI-created tokens: never overwritten by .env changes
- Dark mode toggle: no longer triggers token reload from .env
- Backward compatible: fresh installs with API_TOKEN in .env still work
- Migration path: users can safely keep API_TOKEN in .env, it will be ignored
Future improvement: Add UI warning when API_TOKEN/API_TOKENS still present
in .env, prompting users to rotate tokens via the UI.
