# ── H. daemon node_id 强绑 (C2) ──────────────────────────────────
# RFC-026 P2 multi-daemon live impl (issue #338 §① / RFC-026 §5 P2).
# Two host_supervisor daemons in one container; verifies (i) the
# aggregation the dashboard picker reads truly enumerates both, (ii)
# `create_node` dispatches only to the caller-selected daemon, (iii)
# the OTHER daemon calling get_create_request/ack_create_request on
# the sibling request is rejected as `not_your_request` (§4.1.4 C2
# strong bind — the guard is checked BEFORE the status check, so a
# request that daemonA has already consumed still rejects daemonB).
note "H. daemon node_id 强绑 (C2) — P2 multi-daemon live"

# DaemonA's `config_snapshot` column gets clobbered to '' by the many
# child register paths in scenarios A + F, and `list_host_supervisors`
# filters on `config_snapshot.role`, so H1 would race until the daemon
# heart-beats a fresh snapshot. Cheapest reliable fix: bounce daemonA
# (kill its wrapper + its grandchild agent-node worker + restart) so
# its FIRST heartbeat carries a well-formed snapshot again. Not a
# semantic change — same identity (ntok / node_id / alias) reused.
# Follow-up ticket: fix the child-register path to stop erasing the
# parent daemon's snapshot column (out of scope for P3).

# Pre-fix: spawned child's `#!/usr/bin/env node` shebang fails → insta-die.
# Post-fix: minimalEnv prepends dirname(process.execPath) → child survives.
#
# v2 RACE FIX (Codex catch on commit 84545b4): the prior version killed
# `$DAEMON_PID` (the `nohup anet node start` wrapper) but left the
# wrapper-spawned `agent-node` grandchild alive. Two daemons (the
# survivor + the nvm-sim new daemon) shared the same `daemon_node_id` →
# raced for the same one-shot `pendingEnvBlobs` consume → POST-FIX
# outcome non-deterministic (luck-of-the-pull). New design avoids the
# race entirely by registering the nvm-sim daemon under a DISTINCT
# identity (own ntok + own node_id + own alias). hub C2 token-bound
# routing pushes `create_node` only to the target daemon_node_id, so
# the original `daemon-rfc026` keeps running harmlessly but never
# receives the nvm probe doorbell.
