@coderabbitai full review Please perform a fresh full review of current head c60fcbf while this PR remains draft. Review every changed file in this PR (23 total), including CI/helper report validation, registry and credential fixtures, TestMain dispatch, performance provenance/ownership, and both documentation files. Inspect security, architecture and merge-risk concerns as well as inline correctness findings. Prior draft-skipped status is not a completed review. |

go install module@versionignores the main module, so thego listpin check does not cover the installed dependency graph.
go list -mruns in the repository module and resolves the pinned version there.go install pkg@versionthen builds in module-aware mode outside the main module. In that mode, the build uses the SDK's owngo.modfor transitive dependencies. It does not use the repository'sgo.modorgo.sum. As a result, the SDK version matches the pin, but the dependency set can differ from the repository's resolution. This does not break the build. It matches the PR claim that the tools come "from the exact unreplaced module pin". The behavior is still worth a short comment in the code, so nobody later reads the check as dependency-level provenance.🤖 Prompt for AI Agents

Final review disposition for c60fcbf:
All 86 implementation CI jobs, dynamic Windows coverage (42 roots/84 observed IDs), both Windows helper packages, applicable external checks and current signatures passed. Local CodeRabbit remains explicitly temporarily waived by the user while its service is unavailable; no local review coverage is claimed. |

Published MicroSandbox providers need direct evidence that they consume registry trust, credentials and proxy settings, alongside comparable startup measurements. This adds three isolated Linux cases through the production external
Host.RunImagepath: authenticated TLS through an owned CONNECT proxy, refusal without the fixture CA, and refusal without credentials. The positive case verifies authenticated image response bytes and a guest marker; negative controls require concrete refusal and no created VM. Credential-helper receipts identify the live provider executable without recording credentials.The existing lifecycle case captures ordinary fresh/reused
uptimings and a direct/supervised Info/Find comparison using checksum-verified provider bytes and SDK tools built from the exact unreplaced module pin. Reports preserve revision, SDK/runtime/tool identity, process reaping and startup-event boundaries. They describe warm caches and impose no latency threshold.The shared Go CI helper owns the external-only report mode and SDK tool build. The catalogue grows from 13 suites/74 cases to 14 suites/77 cases (37 built-in, 40 external); the existing parity contracts, caching, deadlines and dynamic Windows conformance gate remain intact. Fixture/performance unit tests run by package, and TestMain preserves runtime-supervisor dispatch before private credential-helper dispatch.
Local validation passed: helper and workspace-fixture race tests, Linux registry/credential-helper unit execution, Linux E2E compilation/vet, Windows helper compilation, module verification, strict Linux lint and scoped hooks. The five-case lifecycle/consumer selection check was a dry run only. Local CodeRabbit remains temporarily waived by the user while its service cannot start; no local review coverage is claimed.
Current-head native reports now prove all 77 cases passed once (37 built-in, 40 external), and the retained performance JSON proves fresh/reused up capture plus 808 reaped Info/Find launches with checkout, SDK, runtime and supervisor identity verified. Windows dynamic conformance passed all 42 discovered roots and 84 observed tests/subtests, with both helper unit packages passing. The original Compose job failed before its UID assertion because Ubuntu security package downloads returned 404; one evidence-supported targeted retry passed the UID check and all 55 Compose cases. All 86 current implementation CI jobs are now successful; no further retry is needed. The image-site Netlify retry is ready for this exact head, and all applicable external checks now pass or have expected conditional neutral/skipped status. Greptile reviewed this exact head with confidence 5/5 and no actionable findings. CodeRabbit completed a full exact-head review of all 23 changed files with no significant valid findings; retained security/architecture and minor advisory notes were independently dispositioned. The workflow scanner’s YAML source-location failure was reproduced, and a semantically identical temporary representation produced exactly the same 30 findings as main. This does not claim the original scanner passed. Interrupted published-provider RunImage cleanup remains a documented hardening coverage limit, with no introduced defect established here. Direct RunImage consumption does not prove ordinary up image metadata resolution, remote-agent downloads, cold-cache performance or general egress denial. External-provider cutover remains gated on the remaining campaign work.
