## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work > - The `codex_local` adapter signs agents in to OpenAI, and a company keeps one default Codex identity in its shared company home > - A login with a DIFFERENT account than the company default is deliberately kept out of the shared home — one agent's sign-in must not switch every unbound agent's credentials — but that left the cross-account login inert: nothing connected the agent the operator was configuring to the credential the login stored > - The stored credential and its company secret already exist; only the last mile — an agent actually using them — was missing > - This pull request reports a non-secret binding claim on the authenticated login and lets the agent page bind that one agent's `CODEX_HOME` to the account's secret, exactly and only when the identities differ > - The benefit is that multi-account Codex becomes one click on the agent that needs it, with company-wide identity untouched ## Linked Issues or Issue Description **What happened?** On an agent's detail page, "Sign in with Codex" using a different OpenAI account than the company default succeeds but changes nothing for that agent. The credential lands in the per-identity store and a company secret names it, but the agent keeps using the company default. The Test keeps reporting that authentication is needed, and no repeat login helps. **Expected behavior** When the operator deliberately signs an agent's page in with a different account, that agent starts using that account. Agents that were not part of the action keep the company default. A same-account login keeps working through the shared company home with no per-agent pinning. **Steps to reproduce** 1. Configure a company whose Codex home holds account A. 2. Open a `codex_local` agent's detail page with a sandbox environment and complete "Sign in with Codex" using account B. 3. Press Test. Before this change the agent still resolves account A and the authentication-needed check returns. ## What Changed - `packages/adapters/codex-local` — the prerequisite shield: `isCodexAuthCachePath` recognizes per-identity credential-store entries, and `seedManagedCodexHome` refuses to symlink, heal, or API-key-overwrite an entry's `auth.json`. The seeding pass runs before every probe and execute; without the shield, an agent bound to an entry would have its stored login silently swapped for the host credential. Static shared config files still copy in. Rotation already survives binding: the sandbox copy-back writes rotated credentials into the identity-keyed store slot. - `server` — the promotion records whether the company default home ended on a different account than the login (any read failure degrades to `false`, so the client can never be told to bind wrongly). After the terminal commit, the routes layer remembers a non-secret claim — the opaque account-home secret id plus that verdict — in a bounded in-memory map, and merges it into the owner read of an `authenticated` `codex_local` session. A restart drops the claim; the panel then shows plain success. - `packages/shared` — `CodexAccountBindingClaim` on the owner session response. It carries no account identifier and no credential byte. - `ui` — the login panel reports the claim upward once. The edit-mode form binds the agent's `CODEX_HOME` to the secret and saves in one step, only when `companyIdentityDiffers` is true. Same-account logins bind nothing on purpose: the company-home refresh already carried them, and an unbound agent keeps following the company default across rotations. Create mode is unchanged. ## Verification - Adapter suite: 381 passed, 1 skipped (includes the new store-entry shield tests and the path-predicate cases). - Server suites (8 files): 130 passed, 15 skipped — including two new route tests that drive a login to `authenticated` and assert the claim with both identity verdicts. - UI render suite: 85 passed — including a panel test that the claim is reported upward exactly once. - `tsc --noEmit` clean in `packages/shared`, the adapter package, and `ui`; `server` clean for the touched file. ## Risks - The bind changes one agent's configuration through the normal agent-update patch, initiated by the operator's own login on that agent's page. The failure direction of every fallback is "offer nothing": a missing claim, a restart, or an unreadable company home all degrade to no bind. - The seed shield narrows what the seeding pass may touch; homes outside the credential store behave exactly as before, covered by the existing seed tests. - Builds on the sign-in credential-resolution fix (#13064), now merged; this branch is rebased onto master and the diff contains only the binding feature. Supersedes #13066, which GitHub auto-closed when its stacked base branch was deleted on merge. ## Model Used Claude (Anthropic) — Claude Fable 5 (`claude-fable-5`), extended thinking, agentic tool use in Claude Code (terminal). **Related PRs (searched; no duplicates found):** #12740, #12082, and #9621 touch adjacent Codex credential sync paths; #8495 is the standing hardening effort for probe auth seeding. ## 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 (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) 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 (no standalone docs cover this flow; the behavioral contracts are documented in-line at each changed site) - [x] I have considered and documented any risks above
