Use user_id-based rate limiting for OAuth authenticated requests.
Previously, rate limiting only applied to API key authentication
because it checked _apiKeyID which is null for OAuth. Now uses
a rate limit identifier that falls back to 'oauth_user_{userID}'
when API key is not set but OAuth authentication is active.

Unfortunately, this PR introduces significant behavior changes. For example, it adds another database migration mechanism via Since there’s currently no solid developer documentation for OpenCATS, Claude struggles to pick up the full project context and conventions. @RussH If we want to merge this PR, we’ll likely need to make substantial follow-up changes to align it with the current architecture and workflows. |
Per maintainer feedback, migrate from custom db/migrations/ folder to OpenCATS' existing Schema.php migration mechanism. Changes: - Add revisions 365-370 to modules/install/Schema.php for: - API keys and sessions (365) - Tearsheets with job/candidate associations (366) - OAuth 2.0 tables (367-368) - Webhook subscriptions (369) - Rate limiting (370) - Remove db/migrations/ folder - Update documentation to reference Schema.php - Remove obsolete audit scripts This aligns with OpenCATS architecture and workflows.

Thanks for the feedback! I've addressed the migration mechanism concern. Changes MadeMigrated from
The database changes now integrate seamlessly with OpenCATS' existing upgrade workflow. Schema.php Additions (revisions 365-370)Please let me know if there are other architectural concerns that need addressing. |

Thank you for that adjustment. @RussH correct me, if I am wrong, but I think it would be easier if you change the base branch from develop to master as develop hasn't been touched since over five years. |

There was a problem hiding this comment.
There also is much noise in this PR, like a new ./github/ISSUE_TEMPLATE or docs/plans/2026-01-25-comprehensive-api-audit.md. Please take a look onto that, thank you!

Can we add one big migration via modules/install/scripts/ instead, @spcaeo? |
