Phase 3 (B1 dual-state + B2): a job never lingers as RUN when its worker
is lost.
Dual-state B1 (user-approved): RDHUP (worker TCP dropped = confirmed dead)
marks its RUN jobs EXIT immediately (mark_worker_jobs_exit). Heartbeat
timeout (unknown) keeps them UNKWN+TRANSIENT awaiting reconnect
reconciliation; the TRANSIENT TTL GC is the backstop. handle_worker_leave
now calls mark_worker_jobs_exit (was mark_worker_jobs_unknown in Phase 2).
B2 (worker side): resend_job_status now checks the recovered process is
alive (kill(pid,0)) before re-reporting RUN — a dead process is reported
finished so the controller converges to EXIT instead of a stale RUN. And
resend_job_status runs on EVERY rejoin (checking_connection), not just
startup, so a reconnecting worker's jobs are reconciled (clears UNKWN via
the existing notify_jobstart claim path).
Design: docs/Job-Finish-Robustness-设计文档.md §4.4 (dual-state decision).
Unit test: worker RDHUP marks jobs EXIT (not UNKWN).
A worker-reported finish may arrive before the job exists: job
construction is deferred to apply_committed_entry (the submit's WAL
entry), leaving a commit->apply window. on_job_finish dropped such
finishes ('can not find job'), so a fast job that finished in that
window stayed RUN forever (e.g. noexec-test/newcfg-test/verify-fix).
Add an in-memory unknown-finish registry: on_job_finish registers the
finish when the job isn't materialized, and apply_committed_entry's
WAL_JOB_SUBMIT case drains it right after restore_job — appending the
durable WAL_JOB_FINISH and mutating the job to DONE/EXIT immediately so
the scheduler never dispatches a job that already finished.
Design: docs/Job-Finish-Robustness-设计文档.md (Part A of A+B; Part B
worker-liveness + reconnect reconciliation deferred to later phases).
Unit tests (red->green): registry register/take, apply-once-job-
materializes (DONE), exit-code maps to EXIT, drain no-op without
registration.
worker/src/resource_sync.c init_builtin_load_indices registers 11 load
indices (r15s/r1m/r15m/ut/pg/ls/it/swp/mem/tmp/io) but resources.yaml only
defined r1m/r15s/mem/tmp. The 7 missing ones (r15m/ut/pg/ls/it/swp/io) caused
controller "update_resval: Success" ERRORs and scheduler "unknown resource in
per-worker resvals update" warnings, leaving the worker resource view
incomplete. Add the 7 definitions matching the existing r1m/r15s pattern.
Docs: log bug-1494 (all jobs PEND, scheduler never dispatches; after this
config fix jobs still PEND — remaining suspect is the scheduler→controller
join path after restart), update design doc + verification manual known-issue
tables and root CLAUDE.md cluster-verification status.

New src/docs/chatbot-verification.md: reproducible steps to deploy the
scheduler-agent stack on the t1/t2/t3 test cluster (AppImage build, store
sync, controller/apiserver/scheduler/worker startup) and verify Phase 0-1
(login, mcp_operator API key, read ops, submit). Documents the vcpus quirk,
setsid launch pattern, conf/current pointer mechanism, and known bugs
(job-control HTTP 500 = bug-1490, HA election deadlock).
Also add the manual to the design doc's related-documents index.

- myconf_t gains peers_cfg (xce_cluster_config_t) populated from --peers
- controller/main.c: parse --peers host:port,... via argp; ca_cert_path
auto-derived from workdir/certs/xce.crt (no --ca-cert flag needed)
- cluster_init: derive my_priority from position in peers list (index 0 =
primary); fall back to 0 when --peers not given (single-node mode)
