## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Native remote runners use a session-owned broker for managed GitHub operations. > - That broker uses the existing authenticated sandbox callback bridge. > - The native caller omitted the server-selected duplex flag. An enabled and capable target still used file polling. > - Warm sessions must observe a changed flag and channel loss before the next admission. > - This pull request forwards the existing flag and retires unavailable or changed bridges before retained instruction preparation. > - The benefit is less idle remote traffic without changing credential authority or the default transport. ## Linked Issues or Issue Description **What happened?** A native GitHub callback bridge selected `queue_v1` even when its sandbox target had duplex enabled and supported it. The file bridge continues remote queue checks while the warm session remains available. **Expected behavior** An enabled, capable target should use the existing HTTP/2 bridge. Disabled or unsupported targets and failed channel startup must retain the authenticated file fallback. A changed server flag must take effect at the next normal warm-session boundary. **Steps to reproduce** 1. Create native GitHub access on a sandbox target with the server-selected duplex flag enabled, verified duplex capability and a working channel. 2. Observe the selected callback transport. 3. Before this fix, it is `queue_v1`. The added real-wire regression expects `http2_v1` and fails on the old source. ## What Changed - Forward the existing server-selected duplex flag through the native GitHub broker. - Record that transport selection on the broker. Retire the warm provider and broker through the existing cleanup path when the flag changes. - Read live channel failure when checking broker readiness. Mark normal session cleanup as an orderly completion. - Include the selected flag in instruction preparation identity. Retire a failed broker before adopting retained instructions, while preserving existing ownership and cleanup fences. - Add real local HTTP/2 credential-rotation and file-fallback controls. Add native warm-session flag-change controls. - Document selection, fallback and warm-session behavior. - Scan CI secret expressions in one forward pass, including quoted braces and escaped apostrophes. Preserve direct, bracket, multiline and whole-context references while rejecting filename and literal-string false positives. ## Verification - Current head `41440b07ea45e9e882e36ed495a66e501c8dd4df` resolves the actual CI-policy conflict with master `307eb16c0c59abd9e0626fde9201939b262e7f5f`. It retains upstream's stricter whole-expression credential guard, including quoted secret text, and uses the forward scanner instead of a backtracking regex. All **16 CI policy tests** pass, including the bounded 28- and 10,000-apostrophe controls in both policy modes. The reported old regex still has its recorded two-second timeout (14 passed, one failed). On this final merged source, **809 affected native cases** pass with zero selected skips (65.20s). Full repository typecheck (31.44s) and build (22.13s) pass. Frozen source hashes stayed unchanged. Fresh exact-head full CI, configured security and completed Apex remain pending. - Before master integration, the frozen native repair passed repository `pnpm -r typecheck` passed (33.0s) and `pnpm build` passed (32.1s). - Before the latest master integration, all **800 affected cases passed with zero selected skips**: complete native executor (725), resume (50), GitHub broker (16), environment duplex-gate (4), and heartbeat instruction-copy (5) suites. The final run took 95.3s. Source hashes stayed unchanged through these checks. - The initial head passed 788 affected cases and full CI, but Apex scored it **3/5**. It found a dead HTTP/2 broker could remain reusable and a flag change could fail after retained instruction preparation. Both findings required the new repair. Three added before-fix regressions failed on channel availability, orderly close, and preparation identity. - The first repair run failed three new warm-instruction fixtures because fake provider close left its recorded state ready. The corrected fixture writes a suspended checkpoint without weakening the production ownership guard. A separate real-wire run then failed two availability assertions because its helper spread had frozen the readiness getter. The helper now preserves the getter. All failed attempts remain in the local evidence. - One disposable real Daytona sandbox exercised both transports on the initial transport patch through the production native broker and callback bridge. The provider shell wrapper used the then-current production declarations. During equal two-second idle windows, file mode issued **9 remote commands** and HTTP/2 issued **0**. Both variants rotated synthetic credentials between two run bindings and denied idle requests. Cleanup deleted the sandbox. - Daytona component setup took 3.64s for file mode and 4.74s for HTTP/2. This is an idle-traffic reduction, not a startup-speed claim. That component run predates the availability and preparation repair; it does not qualify the repaired paths on Daytona. The new failure controls use a real local HTTP/2 channel. The credential resolver was synthetic and no model was called. Real GitHub-account grants, staging replies, and the end-to-end latency target remain unverified by this component test. - Repaired-head CI found a policy-test false positive: a broad `secrets.` regex matched an upstream filename. The unchanged test reproduced the failure, and the corrected version passed all 15 controls. Master later supplied a stronger direct/bracket check, which we retained when resolving the merge conflict. Review then found that formatted expressions could stop that check at a quoted brace. The new reported-case baseline failed (one failed, 14 passed). The final check treats quoted strings as complete tokens, respects expression boundaries, and passes all 15 cases. The later master conflict also added `toJSON(secrets)` controls. The old branch pattern failed that whole-context case. Review subsequently found exponential backtracking with escaped apostrophes; the final forward scanner retains the quoted-boundary and whole-context controls and passes all 15 tests, including the bounded long-expression regression. No workflow or credential handling changed. All failed attempts remain recorded. - The full local repository test suite was not rerun. [Prior-head full CI](https://github.com/paperclipai/paperclip/actions/runs/38775801821), including `ci / verify` and `ci / e2e`, passed on previous head `e5f8bdb425081cf08110c0f7423f96609e405920`. All 52 check runs succeeded, two optional Storybook jobs skipped, and legacy Snyk passed. Completed Apex review is **5/5** on that exact head, with no unresolved review threads. ## Risks - Only an explicit server-selected opt-in can use HTTP/2. The existing provider-capability, channel-startup and authenticated file-fallback checks remain in the shared bridge. - Toggling the flag or losing the HTTP/2 channel replaces an idle retained provider at the next run boundary. Instruction preparation must make the same retirement decision. Normal ownership, settled history and cleanup checks remain in effect. - Lower idle traffic may reduce provider/controller pressure, but no staging latency improvement is claimed. This feature remains inactive when the existing flag is off. Other preparation and finalization costs remain. - No schema, API, UI, credential-selection, tracing endpoint or default-setting changes. ## Model Used - OpenAI Codex, based on GPT-6, with tool-assisted reasoning and code execution.
