Signatures are deterministic (RFC 6979), so the six existing signing vectors get golden outputs recorded with NBitcoin 10.0.9. Any later bump or refactor must reproduce them exactly. Tests that set MF_ env vars share one xUnit collection so they don't race.
- vendor/nspark: Elenpay fork of NSpark (native libspark_frost rebuilt from Lightspark source, NSpark.RemoteSigner contract) as a git submodule. - RemoteSigner references NSpark.RemoteSigner; NBitcoin 10.0.9 -> 10.0.10 (NSpark's minimum). The golden PSBT outputs are unchanged. - Dockerfile builds from the repo root (docker build -f RemoteSigner/Dockerfile .), with a root .dockerignore; justfile, lambda tools defaults and CI follow. - CI checks out the submodule. No behavior change: nothing calls into NSpark yet.
The NSpark changes go as pull requests straight to orklabs/nspark, so vendor/nspark points there. The submodule pins the head of that stack until it merges upstream.
The NSpark changes this signer needs, the RemoteSigner contract among them, are PRs on the Elenpay fork. Pin its stack top until they reach a fork tag.
