dshackle's SIGHUP reload silently fails for upstream REMOVALS (and method-set
changes, same remove+add path): it logs "Config is not reloaded, cause - ...",
updates the in-memory config but leaves runtime selectors stale (drift), and keeps
serving the old config. No runtime admin API exists to mutate upstreams, so a
container restart is the only way to actually apply such changes.
Replace the blind SIGHUP with: per-container SIGHUP, then check post-SIGHUP logs
for the failure marker ("Config is not reloaded, cause -") or a dropped concurrent
HUP ("Reloading is in progress"); on either, docker restart to load config fresh.
"Reloading config has been completed" is NOT success (finally-block) — deliberately
not treated as such. Exit 0 when config ends up applied (via SIGHUP or restart);
non-zero only if a needed restart fails or the container doesn't come back.
Layered on top of the override-weave (apply-dshackle-overrides.py) and the 1:1
invariant gate (validate-dshackle-1to1.py) — both run unchanged before the reload.

Insert validate-dshackle-1to1.py between the overrides weave and the HUP signal:
a dshackle config routing >1 node for the same chain is REFUSED (exit 1) so the
live config stays active. Structural enforcement of 1 dshackle = 1 node/chain —
we can't attribute traffic to multiple nodes behind one proxy (no per-upstream
request metric; conn-seconds biases it). See /root/proxy-1to1-invariant-plan.md.

/root/rpc-local/dshackle-overrides.yaml (host-local, like rpc-local/compose.d) is
re-woven into main_configs/*.yaml by reload_dshackle.sh on every config push.
Method-disable decisions are local to each gateway's market (operator eviction
rule: cost_ratio = time_share/call_share at flat pay); this makes them durable
inputs instead of fragile output patches. Step 1 of moving dshackle config
generation onto the gateway hosts (step 2: ssh forced-command upstreams fetch,
generic dshackle.yaml include list derived from drpc-gateways.json).
