 ### Removed
 
-- Removed pro-reasoning aliases for GPT-5.6 variants
+- Removed the generated GPT-5.6 pro-reasoning aliases (`gpt-5.6-{luna,sol,terra}-pro`) from the `openai-codex` subscription provider — pro reasoning is not offered on subscriptions; the `openai` API-key aliases remain

 ## [Unreleased]
 
+### Changed
+
+- Reduced agent bias against large diffs and refactors in advisor prompts
+- Updated advisor blocker criteria to prioritize explicit user instructions over plan size
+
 ### Fixed
 
 - Fixed MCP OAuth dynamic client registration omitting discovered scopes on the RFC 7591 registration body. Providers such as Clerk bind DCR-created clients to only the scopes declared at registration, then reject the subsequent authorize request when it asks for `openid` (from `scopes_supported`). Registration now includes `config.scopes` when present, matching Claude Code and the scopes already sent on authorize.
