Description

main currently does not build its test tree: #4314 changed MasterService::BatchProbeKey to take a GrantLeasePolicy, but the MasterScenario DSL kept calling the two-argument form, so master_service_test_dsl fails to compile and every PR's CTest unit tests job dies while building the tests (verified on two unrelated PRs: #4736 and #4741, both failing at dsl/scenario.cpp:1926 with no matching function for call to BatchProbeKey(std::vector<std::string>&, TenantId)).

This is a one-call-site fix: pass GrantLeasePolicy{}, i.e. lease_mode = None. The implementation maps that to BatchExistKeyImpl(..., grant_lease=false), which is exactly the lease-free existence probe the DSL step relied on before the signature change, so scenario behavior is unchanged.

Verified by building the affected target (master_service_test_dsl) — it links after the fix.

Heads up: this exact fix already landed via #4729 (merged), which changed the same MasterScenario::Then(BatchProbeSpec) call site to BatchProbeKey({}, keys, TenantId(...)), passing an empty GrantLeasePolicy just like this PR's GrantLeasePolicy{}. The remaining diff between the two is only formatting, and this branch now conflicts with main because both touched the same lines.

Could you rebase onto current main and check whether anything remains? If the DSL step builds clean now, this can probably be closed; if you intended the DSL to thread a real (non-default) lease policy from BatchProbeSpec, that part would need to be reworked on top of the merged fix.

Thanks @he-yufeng — confirmed, #4729 landed the same call-site fix ( BatchProbeKey({}, keys, TenantId(...)) ), so this PR is redundant and I am closing it rather than keeping a duplicate. My branch only existed to keep two unrelated PRs buildable while main was broken; I am dropping that commit from both of them and rebasing onto current main, so nothing from this PR remains in flight.
