## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Product E2E evaluations use a budget ledger and a local model gateway. > - The gateway writes each request reservation before it calls a provider. > - A client can cancel before the gateway returns response headers. > - Project-only logging context cannot then bind a late gateway log to its reservation. > - This change sends the reserved request identity in Braintrust log metadata before dispatch. > - Operators can use that identity to inspect late records without guessing from time or session order. ## Linked Issues or Issue Description Refs: #17009 **What happened?** A hosted evaluation passed its product checks but retained two canceled requests with no response headers. Later gateway logs had partial usage. Their time and session matched, but they had no ledger request identity. **Expected behavior** A gateway log must carry the ledger request ID even when the client receives no headers. A log match must not imply final billing. **Steps to reproduce** Run the gateway regression with a transport that receives a request and then cancels before response headers. Before this change, both requests have the same project-only parent header. ## What Changed - Add a small Braintrust context encoder owned by the eval gateway integration. It uses the existing SpanComponentsV4 project-log format and an allowlist of request, campaign, execution, attempt and phase metadata. - Save the exact context in the private request receipt before dispatch. Send it as the gateway parent header. - Test both provider routes, repeated identical requests, cancellation holds and direct-provider isolation. - Document the lookup field and the limits of historical and partial evidence. ## Verification - The new cancellation regressions failed before the change: 2 failed, 37 passed. - Gateway, operations and tracing checks: 82 passed. - `pnpm test:e2e:runner:typecheck`: passed after rebuilding stale generated plugin-SDK types from current master. The initial stale-type failure remains recorded locally. - Official Braintrust SDK 3.38.0 decoded the actual generated context. Its `startSpan` implementation emitted the reserved identity in the initial LLM log. The check captured logs in memory and forbade all network calls. - `git diff --check`: passed. - Full repository CI passed on `529446a9295f2dc6fa6499a2f976480d74626097`, including typecheck, tests, build and both required gates. Greptile is 5/5 on that head; its sole finding is fixed and resolved. - The optional Paperclip review turn ended without a final response. Its check remains queued and provides no review assessment. No passing review is inferred from it. - Live hosted acceptance of this header change remains unqualified; no paid test was dispatched for this fix. ## Risks - The encoder follows Braintrust's versioned span format. A future vendor change can require an update. It adds no package dependency. - A late log can have partial usage. Existing reservations remain held until valid cost evidence resolves them. - Historical project-only requests cannot gain the new identity retroactively. - Only synthetic eval identifiers enter the new metadata. Credentials, prompts and responses are excluded. Direct provider routes keep their current headers. ## Model Used OpenAI Codex, GPT-6 family. The exact deployment ID and context-window size are not exposed in this session. Used reasoning, repository tools and code execution. No paid evaluation model calls were made for this change. ## 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>
