- .claude/skills/xce-deploy-ha/SKILL.md: new skill for deploying a
local 3-node XCE HA controller cluster. Covers build prerequisites,
deploy via src/tools/deploy-ha.sh, node startup with -vvv raft trace,
health verification checks, clean restart procedure, and a
troubleshooting table for common failure modes.
- src/controller/CLAUDE.md: add HA Cluster Deployment section with
quick-deploy commands, health check one-liners, and reference to the
xce-deploy-ha skill. Add src/tools/deploy-ha.sh to key files.
- create_lost_and_found(): provide hostattrs_t so makeWorker succeeds
- collect_queues/collect_workers (dataex.c): skip lost_and_found sentinel
so it is never pushed to apiserver or scheduler
- mark_worker_unavail(): reset hosttype/hostmodel to "unknown" and zero
all numeric attrs, then update resvals and slots — prevents stale
capacity from being visible while the host is down
- restore_worker(): apply the same attr reset on WAL recovery so
restored-but-unavailable workers advertise no capacity until reconnect;
also remove dead calloc() that was immediately overwritten by makeWorker
- Extract reset_hostattrs_unknown() helper to eliminate copy-paste
- Define XCE_LOST_AND_FOUND_NAME constant in config_repl.h; replace all
six raw "lost_and_found" string literals across config_repl.c and dataex.c
