The release branch still had unresolved review comments around payload-rule
atomicity, brand blocking, compact fallback controls, and response
compatibility edge-cases. This patch pulls those behaviors back in line with
the intended contracts and adds focused regression coverage for the fragile
bridges.
Constraint: The fixes must stay narrow to the PR branch so review/merge can continue without reopening the larger dev snapshot conflict set
Rejected: Leave outdated-looking threads unresolved until after merge | reviewers still see concrete unfixed regressions in the current release branch
Rejected: Re-run another broad merge from dev/main | too risky while the PR branch is already green and mergeable
Confidence: medium
Scope-risk: moderate
Directive: If these release-branch fixes need to persist for future release cuts, backport them onto dev instead of re-fighting the same review threads next time
Tested: Focused vitest for settings events, brand matcher, compact responses, codex compatibility, anthropic stream bridge, openai chat response bridge; typecheck; repo drift check; git diff --check
Not-tested: Full npm test; live PR thread resolution state after push
The root checkout already contained a large in-progress proxy, transformer,
and settings refactor. This commit captures that exact work on a dedicated
local dev branch without disturbing the original dirty worktree, so the
changes can be continued or split from dev instead of living only as
uncommitted state.
Constraint: The source checkout was already dirty on another branch, so the move had to preserve that worktree while excluding local .idea and .omx residue from the commit
Rejected: Switch the dirty root checkout directly to dev | risked disrupting the original branch and in-progress state
Confidence: medium
Scope-risk: broad
Reversibility: clean
Directive: Treat this as a transfer snapshot; fix the failing oauth/accountTokens/normalized/docs test regressions before merge or publication
Tested: git diff --check; npm run typecheck; npm run repo:drift-check
Not-tested: Clean test pass; npm test currently fails in oauth routes, accountTokens sync, shared normalized helpers, gemini route expectations, architecture-boundaries, and docs vitepress config
