      "bug-1548/bug-1549: apiserver never re-registered with a new primary after a fast controller failover. Fixed via tasks.md Phase 6 -- endpoint_t.reconnect_gen counter (netio.h/xcectx.c) bumped on every successful transport reconnect, heartbeat.go's runHeartbeat replaced its failure-to-success transition detector with a per-tick generation comparison. Confirmed via live E2E re-run of task 5.2's exact scenario: rejoin fired 22s after primary kill (12s after new election) with zero write traffic for the preceding 5.5 minutes; a post-recovery diagnostic job submit correctly appeared via GET /xce/v1/jobs.",
      "bug-1559: xce-build.sh's scheduler case didn't build/run 4 newer scheduler test binaries. Fixed directly (tooling, not a spec task) -- now runs `meson test --suite scheduler`, exercising all 41 scheduler test binaries.",
      "bug-1558: make test-backend broken standalone. Fixed directly (tooling, not a spec task) -- self-derives CGO_CFLAGS/CGO_LDFLAGS via pkg-config, confirmed working with zero manual env setup."

Remediated as tasks.md Phase 6 (6.1/6.2) plus two non-blocking build-tooling fixes (bug-1558, bug-1559) found during the same validation pass."
