+### Changed
+- The real-hub CI job now also runs real govulncheck 1.9.0 and grype 0.121.3 through `review_checks.sh`, each on a fictional canary; the job fails unless the tool ran and reported its expected rule on that file with no not-run or NOT CHECKED line. grype is pinned by sha256 from the release `grype_0.121.3_checksums.txt` (the linux_amd64 archive is also checked against a literal hash). govulncheck ships no release binaries, so it is built from source with `go install` on the pinned Go 1.26.11 (`GOTOOLCHAIN=local`), the module hash `h1:` is asserted from `go version -m`, and the Go checksum database verifies the source. The canaries: govulncheck calls `yaml.Unmarshal` of the real module gopkg.in/yaml.v2 2.2.2 (GO-2020-0036, GO-2021-0061, GO-2022-0956; `go mod tidy` fills `go.sum` and the module cache, then the hub runs with `GOPROXY=off`); grype scans a one-component CycloneDX SBOM (lodash 4.17.15, GHSA-35jh-r3h4-6jhm), because the hub points grype at SBOM files only, never at a lockfile.
+- Both vulnerability databases are fetched online and are not pinned: govulncheck's `-db` flag has no env override, so it reads vuln.go.dev at run time (no offline pin is possible without changing the hub command), and the CI step runs `grype db update` (grype verifies the archive against the listing checksum; a dated archive pin would rot when upstream rotates it out). The canary advisories are old, so a DB refresh does not remove them.
+- Follow-up: the real-hub job timeout is 25 minutes, the govulncheck install, `grype db update`, `go mod tidy` and the hub run (while govulncheck or grype is not run) each retry up to 3 times with backoff, and the grype canary also accepts the CVE aliases of its advisories. The canary `go.mod` stays at the repo root because the hub runs govulncheck only from a root `go.mod`; the test asserts gosec and staticcheck report nothing on the govulncheck canary package.
