CORE_RPC_HOST was hardcoded to bitcoin-knots in three env-render paths, so on a
bitcoin-core node (container named bitcoin-core) mempool-api could not reach
Bitcoin RPC. Both node variants are reachable on archy-net by container name —
only the name differs.
- Legacy direct-podman (stacks.rs) and config.rs::get_app_config now use a new
dependencies::detect_bitcoin_rpc_host() (pure, unit-tested pick_bitcoin_host).
- Quadlet/manifest path (the modern fleet default): add a {{BITCOIN_HOST}}
derived-env placeholder — HostFacts.bitcoin_host + resolve_derived_env render
it; prod_orchestrator detects Knots/Core via podman ps, resolved on demand
only for manifests that use the placeholder. mempool-api manifest moves
CORE_RPC_HOST from static env to derived_env: {{BITCOIN_HOST}}.
Tests: pick_bitcoin_host (5 cases incl. substring safety), container-crate
resolve_derived_env, and orchestrator mempool_core_rpc_host_follows_bitcoin_node
(core->bitcoin-core, knots->bitcoin-knots). No-regression confirmed: picker
returns bitcoin-knots live on .198. Live bitcoin-core validation pending (no
core node available). Sibling hardcodes (lnd/btcpay/electrumx/fedimint) tracked
as B12b.
