📝 WalkthroughWalkthroughThe change snapshots the provider replay checkpoint emission gate from deployment configuration and forwards it through hosted chat execution to runtime creation options. Tests cover environment precedence and checkpoint option propagation. ChangesProvider replay checkpoint gate
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The PR changes hosted checkpoint emission to use the deployment-time gate while preserving default-off behavior. Production impact is bounded to whether durable replay checkpoints are emitted under the intended configuration; merge is reasonable with owner awareness because the new handoff test should use the repository’s shared BDD helpers to ensure all supported test runners execute it.

Automated Review — Score: 85/100 (Good)Small, well-targeted bug fix that snapshots the provider-replay emission gate at service-context creation instead of re-reading it during request-scoped preparation, with backward-compatible fallback and solid regression coverage. Strengths
Minor concerns (non-blocking)
Nothing here blocks merge; the CHANGELOG gap is the only thing I'd actually ask for before merging per the repo's own checklist. Generated by Claude Code |

Code Review ✅ Approved 1 resolved / 1 findingsFixes provider replay checkpoint gate snapshot at bootstrap by capturing the deployment configuration once during service context creation and threading it through hosted execution preparation, preventing the gate from being read during request preparation where environment variables could override the deployment setting. An absent gate variable now correctly falls back to disabled rather than triggering host environment defaults. All focused tests, formatting, linting, and type checks pass. ✅ 1 resolved✅ Edge Case: Absent gate var falls back to host env, defeating snapshot

Summary
The deployed issue #522 canary proved that the provider and runtime emit signed checkpoints when private bindings are present, but the hosted service emitted none while the Kubernetes env was set. The gate was being read during tenant-scoped request preparation instead of being captured with deployment configuration.
Scope
Verification
Refs veryfront/veryfront-issue-inbox#522.
Required for the real staging conversationless provider-replay canary; production emission remains disabled.
