[claude 2026-08-22] From the mutation baseline. syncclient is the agent's link to the control plane and scores 76.19% efficacy — 32 killed, 10 lived, 6 unreached, 5 timed out.

Surviving mutants, all in client.go:

LIVED CONDITIONALS_BOUNDARY at client.go:152:20
LIVED CONDITIONALS_BOUNDARY at client.go:171:44
LIVED CONDITIONALS_NEGATION at client.go:212:116
LIVED CONDITIONALS_NEGATION at client.go:265:10
LIVED CONDITIONALS_NEGATION at client.go:288:14
LIVED CONDITIONALS_NEGATION at client.go:337:14
LIVED CONDITIONALS_NEGATION at client.go:443:41
LIVED CONDITIONALS_NEGATION at client.go:469:27
LIVED CONDITIONALS_NEGATION at client.go:529:55
LIVED CONDITIONALS_NEGATION at client.go:645:10

Also the slowest package to mutate (445s), because its suite is 10s. The 5 timeouts are its own doing, not the ext4 artefact.

Rerun: make mutate PKG=./internal/agent/syncclient.
