Both electrumx tests did socket.create_connection(("127.0.0.1", 50001)) and
called it proof the service was up. It is not: that is the HOST-published
port, and podman's port forwarder completes the TCP handshake even when
nothing inside the container is listening.
The cost was real. Both tests were green while mempool-api sat in a hard
ECONNREFUSED loop against electrumx:50001 from inside archy-net — the
operator's "mempool doesn't connect to bitcoin". Measured side by side:
127.0.0.1:50001 from the host OPEN, electrumx:50001 from a sibling container
REFUSED.
The cause is not a misconfiguration — mempool-api's CORE_RPC_HOST,
ELECTRUM_HOST and ports are all correct. electrumx has not finished its
initial sync (DB height 959,774 vs chain tip 961,706, ~1,932 blocks, 8d 14h
elapsed) and ElectrumX does not serve sessions until it has caught up.
Now both tests do a server.version round-trip and require a JSON result, so a
forwarder that accepts-and-drops fails. Verified against the live node: the
new probe FAILS today where the old one passed.

Rename run-20x.sh → run-gate.sh, default ARCHY_ITERATIONS 20→5, and scrub
20× references across CLAUDE.md, the master plan, TESTING.md, app-registry
status, the orchestrator/config doc-comments, and the bats suites. Also add
a minimal fail() helper to mempool.bats so guard failures report cleanly.

Same shape as bitcoin-knots.bats and lnd.bats so the 20× release-gate
exercises electrumx through the same state matrix it uses for the other
two core apps. electrumx previously had a single TCP-port check inside
required-stack.bats; this adds destructive + cascade-destructive tiers.
10 @test cases:
* read-only: presence, valid state, TCP port (50001) reachable, no
orphan containers beyond {electrumx, archy-electrs-ui}
* destructive: stop, start, restart, TCP port recovers within 120s of
cold restart (longer than bitcoind because electrumx replays its
index against bitcoind on start)
* cascade: uninstall, reinstall (240s timeout for index rebuild)
With this suite, the three single-container core apps (bitcoin-knots,
lnd, electrumx) now have parity coverage. Multi-container stacks
(btcpay, mempool, fedimint) come next.
