## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - External channels deliver agent replies through a durable publication queue. > - A provider can reject one operation while other operations remain allowed. > - The shared error classifier treated generic 403 and permission errors as failures of the whole connection. > - Failure handlers then changed the user's enabled setting and removed all assigned channel tools. > - This pull request limits permission failures to the rejected operation and preserves connection intent during authentication failures. > - Unrelated work can continue, while confirmed authentication failures still stop endpoint traffic. ## Linked Issues or Issue Description Refs #16137. Follows #16138, which distinguishes local authorization errors from provider errors. This change also narrows provider permission failures. Related #16806 handles a separate task-continuation tool-binding defect. A provider 403 or missing-scope response currently disables a connection that may still support other operations. The expected behavior is a visible operation failure with unrelated work preserved. Confirmed authentication failures must stop sends without changing the user's enabled setting. ## What Changed - Classify generic 403, adapter permission errors, and Slack missing-scope/no-permission responses as failed operations. - Preserve rate-limit retries, known destination quarantine, and confirmed authentication failures. - Preserve connection status and enabled intent when publication, provider-reply, or form-open authentication fails. The endpoint still enters attention and its runtime stops. - Add GitHub regressions for retained discovery and successful later publication after 403, and no further sends after 401. - Mark authentication health failed and fence persistent receiver startup, background reconciliation, and receiver callbacks. Keep signed GitHub lifecycle events available during an authentication stop. Verify Discord reconciliation and Photon restart preserve the stop, while transient Discord disconnects still recover. - Update provider, publication, and modal regression expectations and the execution contract and verification maps. ## Verification - Red: five new classifier cases returned endpoint attention before the repair. The signed-installation-removal regression also reproduced a blocked lifecycle event after a 401 before narrowing the receiver guard. - Green: all 35 classifier tests pass. - Green: 19 PostgreSQL-backed cases pass through the production channel services, including GitHub discovery/publication, Slack provider replies and question modals, Telegram credential/destination failures, rate limiting, and Discord/Photon authentication-stop persistence. - Map structural checks and `git diff --check` pass. - `pnpm -r typecheck` and `pnpm build` pass. All CI gates are green on `7e379bcd98aa8363e42efe7f8a4b2589b7111ae6`; Greptile is 5/5 on that exact commit with no unresolved findings. - The monolithic local `pnpm test:run` was started, then stopped after its revision passed the full CI matrix and was superseded by the authentication-stop repair. Final full-suite verification passed in CI shards; all 19 final local provider regressions pass. - The tests run from this source checkout on macOS arm64 with isolated PostgreSQL and controlled provider failures. They do not prove live GitHub recovery or deployment. No live connection settings were changed. ## Risks - Permission failures now leave unrelated work available. The rejected operation remains failed and is not automatically replayed. Provider authorization still applies to every request. - Keeping a connection enabled must not bypass an authentication stop. GitHub verifies blocked tool discovery and later sends; Discord and Photon verify background reconciliation and restart cannot clear the stop. Failed connection health is an execution gate while the endpoint requires attention. - Explicit disable, disconnect, signed installation revocation, and existing destination-specific denial handling remain unchanged. No migration or API schema change is required. - Previously disabled connections are not automatically re-enabled because an upgrade cannot safely infer the user's intent. ## Model Used - OpenAI Codex, GPT-6 family. The runtime does not expose the exact deployment model ID or context-window size. Used reasoning, shell tools, repository edits, and test execution. ## 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 - [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>
