# Run the git-refs canary in PR CI (matrix over checkpoint backend)

`eedee7d`·

Soph·2w ago·1 file·+8 added/-0 removed

ci.yml's test-canary job now runs as a matrix over checkpoint_store
\[git-branch, git-refs\], setting E2E_CHECKPOINT_STORE. The Vogon canary makes no
API calls, so this guards the git-refs store on every PR at no cost alongside the
default git-branch run. fail-fast: false so one backend's failure doesn't mask
the other.

(The e2e-checkpoint-store dispatch workflow already landed separately on main in
#1567; this branch leaves it untouched.)
