wn prints either JSON (with --json) or a yaml-ish "key: value" pretty
form depending on the command and build. On the user's macOS run,
create-identity printed yaml ("pubkey: npub1..."), the subsequent
wn --json whoami didn't return the expected JSON shape, and
ensure_identity bailed with "could not determine npub for B".
Add a shared extract_pubkey helper in lib.sh that tries, in order:
1. JSON object .pubkey / .npub / .public_key
2. JSON array .[0].pubkey / .[0].npub / .[0].public_key
3. yaml-ish "pubkey: ..." via sed
4. yaml-ish "npub: ..." via sed
ensure_identity and prompt_for_a_npub now use it, and also fall back
to the non-JSON whoami output if --json returns nothing. On total
failure, the raw output is echoed to the log for diagnosis.
Also made npub_to_hex best-effort with the same double-try approach.
When hex lookup fails, it returns the npub unchanged — downstream
expect_contains assertions work against either form since wn's own
group listings may use either encoding.

Interactive bash script under tools/marmot-interop/ that validates
Amethyst's Marmot/MLS implementation against the whitenoise-rs wn/wnd
CLI. Builds wn/wnd from source on first run, launches two daemons for
Identities B and C, configures public (or --local-relays) Nostr relays
shared with Amethyst, then walks a human operator through 13 scenarios
covering MIP-00 KeyPackages, MIP-01 metadata, MIP-02 Welcome,
MIP-03 group messages, admin changes, reactions, concurrent-commit race,
leave, offline catch-up, and KeyPackage rotation. Push-notification
(MIP-05) test opt-in via --transponder.
No Amethyst code is modified — black-box testing only. State (daemon
sockets, logs, whitenoise-rs checkout, results TSVs) is kept under
tools/marmot-interop/state/ and gitignored.
