Next review available in: 17 minutes Limit details: You’ve used all 1 included review currently available under your plan. You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This PR changes provider execution and scheduled maintenance, but the current implementation can disable TLS verification in the production serving path, potentially exposing provider credentials, and does not enforce a fixed retry-attempt limit, allowing requests to consume resources for an excessive time. These concrete security and availability risks should be fixed before merge. Sequence Diagram(s)sequenceDiagram

time.sleep은 요청 스레드를 차단합니다.server.py의_run과_stream_route_completion은 실행 슬롯을 잡은 상태로 이 경로를 호출합니다. 따라서 백오프 동안 동시 실행 슬롯이 계속 점유됩니다. 상한이 30초이므로tool_retry_attempts를 크게 설정하면 슬롯 고갈 시간이 길어집니다.또한 지연이 결정적입니다. 여러 요청이 같은 rate limit이나 timeout으로 동시에 실패하면 재시도가 같은 시점에 몰립니다. 소량의 무작위 jitter를 추가하면 이 동기화를 줄일 수 있습니다.

clarification to the related section.
- Around line 93-95: Clarify the audit event schema in the documentation by
explicitly defining failure_kind as the effective failure kind and
distinguishing it from observed_failure_kind, which preserves the original
normalized cause for ambiguous outcomes. Keep the field names consistent with
the sample event and HTTP contract, and document both fields’ roles.

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -
Result: REQUEST_CHANGES
-
Reason: coverage-evidence result was
failure, so required test/docstring evidence was not proven for current head0f1d30a58617cf0ec5838e3319d109c688eef82b. -

Problems
Tool-execution availability and safety
AppGuardrail run
31803400831, job94776449119, stopped in Strix with:The previous provider failover path treated all exceptions alike. That is acceptable for a missing tool, but unsafe for a timeout after a state-changing tool call because the first call may already have completed.
Stalled pull-request repair cadence
Contextual Orchestrator also lacked a repository-owned heartbeat for its central review-repair contract. The bounded caller consolidated from stacked PR #570 is now part of this branch, so the product can request one exact-target repair opportunity per hour without copying the central writer or model credentials into this repository.
Tool fallback change
Add a provider-neutral tool failure contract and deterministic fallback policy:
The exact Strix error is recognized through a bounded, cycle-safe cause chain. Adapters can instead raise
ToolExecutionErrorwith structuredkind,idempotent, andoutcome_unknownmetadata.Legacy HTTP tool adapters receive conservative status handling. Provider authentication failures without tool evidence remain provider failover errors rather than being misclassified as tool permission failures.
MAX_TOOL_RETRY_ATTEMPTSis the shared policy ceiling. Configuration rejects more than four same-agent retries and_invokereapplies that ceiling defensively if runtime state is mutated.Hourly maintenance change

Documentation
This PR intentionally does not add speculative parallel execution, endpoint racing, automatic tool-name substitution, permission bypass, a second repair engine, or model credentials to the leaf repository.
Closes #567.
