## Thinking Path > - Paperclip manages agent work as issues and pull requests. > - This change lives in the Codex local adapter path. > - The host auth flow needs a stable cache per identity. > - The cache must not change the copy-back path or the default store overwrite. > - This pull request adds that cache and keeps the existing flow intact. > - The benefit is repeatable host auth with safer identity scoping. ## Linked Issues or Issue Description **Subsystem affected** - packages/adapters: Codex local adapter and host auth flow **Problem or motivation** - The host auth flow needs one usable credential per identity. - The current flow does not keep that identity state in a separate cache. **Proposed solution** - Add an identity-keyed host credential cache. - Keep the cache company scoped. - Add an opt-in seed mode for the merge decision helper. - Write the cache at copy-back time without changing the default store overwrite. **Alternatives considered** - Store the cache in the instance-global root. - Seed the host default store through an environment flag. - Both choices weaken isolation or caller control, so I did not use them. **Roadmap alignment** - I checked `ROADMAP.md`. - I found no direct overlap with an active roadmap item. - The change fits the core auth and secrets direction. **Additional context** - Local tests passed before I opened this pull request. - I found no direct duplicate pull request for this branch. ## What Changed - Added `codex-auth-cache.ts` for company scoped cache storage and identity anchored vending. - Added `codex-auth-merge-decision.cjs` support for a leading `--seed-if-dest-absent` flag. - Updated `codex-auth-copyback.ts` to write the cache at teardown under the merge lock. - Wired `execute.ts` to use the identity anchored vend before the managed home seed step. - Added `CODEX-AUTH-CACHE.md` for the cache rules, directions, state matrix, off switch, and clear action. - Added and updated tests for cache behavior, merge decision flow, and copy-back flow. ## Verification - `pnpm --filter @paperclipai/adapter-codex-local exec vitest run`. - `node_modules/.bin/vitest run --project @paperclipai/adapter-utils workspace-restore-merge`. - `tsc --noEmit` in `packages/adapters/codex-local`. - `git log --oneline origin/master..origin/feat/codex-auth-identity-cache` shows the expected commits. ## Risks - This change touches credential storage. - A mistake in the cache path could break host auth for one identity. - The tests reduce this risk, but the surface stays sensitive. ## Model Used - OpenAI Codex, GPT-5, tool use enabled. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used with version and capability details - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either linked existing issues with `Fixes:` / `Closes:` / `Refs:` or described the issue in the pull request body - [x] I have not referenced internal or instance-local Paperclip issues or links - [x] My branch name describes the change and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
