Claude fc99bed55a fix(cli): default amy launcher to C.UTF-8 so emoji argv survives
`marmot message react "$gid" "$id" "🍕"` was producing a kind:7 whose
inner content was four `U+FFFD` replacement characters instead of the
emoji. Whitenoise's `message_aggregator::emoji_utils` rejected it with
`Invalid reaction content: ����`, and the openmls receiver retried the
event ten times before giving up — by which point the secret tree had
already consumed that generation, so the retry surfaced as a confusing
`Ciphertext generation out of bounds 1 / SecretReuseError`. That last
error was a downstream symptom; the root cause is argv decoding.

Why it happens: JEP 400 (Java 18+) pins `file.encoding` to UTF-8 but
deliberately leaves `sun.jnu.encoding` — the encoding the JVM uses to
decode argv, filenames, and native interop strings — tied to the OS
locale, and `sun.jnu.encoding` is read **before** the JVM parses any
`-D` flag, so it can't be overridden via `applicationDefaultJvmArgs`.
Under POSIX/C locales (no `LANG`/`LC_ALL` set, common on CI runners
and stripped-down containers) `sun.jnu.encoding` ends up at
`ANSI_X3.4-1968` — i.e. ASCII — and every byte > 0x7F in argv lands
as `U+FFFD` before our code ever sees it. The four UTF-8 bytes of 🍕
(F0 9F 8D 95) become four replacement chars, get signed into the kind:7
content, and the test fails on receipt.

The only place we can set the encoding from is the launching shell.
Patch the gradle-generated start scripts (POSIX `amy`, Windows
`amy.bat`) right after `:cli:startScripts`:

* POSIX: if neither `LANG` nor `LC_ALL` is set, `export LANG=C.UTF-8`
  before invoking Java. Existing locale settings are respected.
* Windows: `chcp 65001` to switch the console to UTF-8 before Java
  runs.

Tested manually: with `LANG=` (sandbox default) `amy` previously sent
`argv[0]=????` for an emoji argument; with the patch it sends `🍕` and
`sun.jnu.encoding=UTF-8`, and whitenoise accepts the kind:7 reaction.

The interop test 09 polling also needed a fix unrelated to the
encoding bug: wn aggregates kind:7 reactions onto the anchor message
under `.reactions.by_emoji.<emoji>` instead of surfacing them as
standalone messages whose `.content` is the emoji, so the previous
`wait_for_message B "$mls_gid" "🍕"` would have failed even with a
correctly-decoded reaction. The new poll inspects each message's
`.reactions.by_emoji` keys for the emoji literal.

Marmot interop score: 15/16 → **16/16** 🎉

amy CLI test harnesses

Shell-based end-to-end harnesses that drive the amy CLI binary against a loopback nostr-rs-relay. Layout:

    ├── setup.sh                    # preflight + identities
    └── tests-dm.sh

The Marmot harnesses come in two flavours, same scenarios:

  • marmot/marmot-interop.sh — interactive. Drives B/C via wn and prompts the human to perform each Amethyst-side step in the mobile UI (Identity A). Use this for final UI verification.
  • marmot/marmot-interop-headless.sh — zero prompts. Drives A via the amy CLI (./gradlew :cli:installDist) and B/C via wn. Runs every scenario end-to-end and exits with a pass/fail summary. Use this for CI and for iterating on the Nostr/Marmot plumbing without needing to touch a phone.

A third, slimmer harness covers the NIP-17 DM surface:

  • dm/dm-interop-headless.sh — two amy processes (Identity A and Identity D) exchange NIP-17 DMs through the loopback nostr-rs-relay. No whitenoise-rs required — only amy and the relay binary (which is shared with the Marmot harness's checkout at marmot/state-headless/nostr-rs-relay/).

Both Marmot harnesses validate Amethyst against whitenoise-rs (https://github.com/marmot-protocol/whitenoise-rs), the reference Rust implementation that powers the White Noise Flutter app. Every test records a pass/fail/skip result into a tab-separated log, and the summary is printed at the end of the run.

What gets tested

# Test Needs 3rd identity
01 KeyPackage publish & discovery (MIP-00)
02 Amethyst creates group, invites wn
03 wn creates group, invites Amethyst
04 3-member group, add-after-create yes
05 wn adds Amethyst to existing group yes
06 Member removal + forward secrecy yes
07 Group metadata rename round-trip (MIP-01)
08 Admin promote / demote yes
09 Reply / react / unreact (inner event kinds 9, 7)
10 Concurrent commits race
11 Leave group
12 Offline catch-up / replay
13 KeyPackage rotation

DM (amy ↔ amy, NIP-17) — dm/dm-interop-headless.sh

# Test
dm-01 Text round-trip A↔D (kind:14)
dm-02 dm list returns prior exchange with type:text discriminator
dm-03 Strict kind:10050 refuses sends to an inboxless recipient
dm-04 --allow-fallback opts into the NIP-65 read / bootstrap chain
dm-05 File message reference mode round-trip (kind:15 with manual key/nonce)
dm-06 dm list --since filters out older messages (window-slide past the newest event returns 0)

Relay binding note: the DM harness binds the loopback relay to 127.0.0.2 (not 127.0.0.1) because Quartz's RelayTag.parse rejects localhost URLs via isLocalHost() — so ws://127.0.0.1 in a kind:10050 event is silently stripped during recipient-relay resolution, which would make strict-mode DM sends spuriously fail. 127.0.0.2 is still pure loopback and isn't matched by that filter. Override with --host 127.0.0.5 etc. if 127.0.0.2 is taken.

Note: dm-05 validates the kind:15 wire format via reference mode (caller supplies the URL + AES-GCM key/nonce). The upload-mode variant (dm send-file --file PATH --server URL) needs a local Blossom server and isn't scripted here — the upload classes are unit-tested on desktop at desktopApp/src/jvmTest/kotlin/.../service/upload/. | 14 | Push notifications (MIP-05) | opt-in via --transponder |

Prerequisites

On the machine that runs the harness:

  • Rust 1.90+ — install via https://rustup.rs
  • git, curl, jq — package manager
  • ~5 GB disk for the first-run build of wn + wnd
  • Public internet access (for the default relay set and fetching crates)

On the Android side:

  • Amethyst installed on an emulator or a physical device
  • The device must reach the same relays the harness uses (see below)

Quick start

cd tools/marmot-interop
./marmot-interop.sh

The script will, in order:

  1. Verify jq, git, cargo etc. are present.
  2. Clone whitenoise-rs into state/whitenoise-rs/ and build wn/wnd (release, --features cli). First build takes ~5 minutes; subsequent runs reuse the binaries.
  3. Launch two wnd daemons (one for Identity B, one for Identity C).
  4. Create Nostr identities for B and C, persist their npubs in state/run.env.
  5. Ask you to paste your Amethyst account npub (Identity A). This is cached for subsequent runs.
  6. Add the default public relays to both daemons and run a sanity check (publish a KP from B, fetch it from C).
  7. Print an Amethyst setup checklist — add the same relays to Amethyst, publish a KP, verify you are logged in with A.
  8. Run all 13 tests sequentially. Each test either:
    • runs wn commands fully automatically and asserts on JSON output, or
    • prints a "DO THIS IN AMETHYST" prompt and waits for you to press <Enter>, then verifies the Amethyst action via wn.
  9. Stop the daemons and print a results table.

Command-line flags

--local-relays    Use ws://localhost:8080 instead of the default public relays.
                  Required if the public relays reject kinds 444/445/30443.
                  Run 'just docker-up' inside whitenoise-rs first.
--transponder     Run Test 14 (push notifications via the transponder service).
--no-build        Fail instead of rebuilding wn/wnd. Useful when iterating.
-h, --help        Show help.

Environment overrides:

WN_REPO=/some/path/whitenoise-rs   # use an existing checkout

Default relays

wss://relay.damus.io
wss://nos.lol
wss://relay.primal.net

These are known to accept kind 1059 (gift wraps) and kind 30000+ (addressable events). If the sanity check fails — meaning C cannot read the KeyPackage that B just published — the harness warns you and continues. In that case re-run with --local-relays after starting the Docker stack:

cd state/whitenoise-rs
just docker-up
cd ../..
./marmot-interop.sh --local-relays

For Amethyst with --local-relays:

  • Android emulator: add ws://10.0.2.2:8080 to Settings → Relays and Settings → Key Package Relays.
  • Physical device on same Wi-Fi: add ws://<laptop-LAN-ip>:8080.

How human interaction works

When the script needs you to do something in Amethyst, it prints a yellow block like this:

---- DO THIS IN AMETHYST ----
In Amethyst:
  1. Tap + -> Create Group
  2. Name: Interop-02
  3. Add member: npub1abc...
  4. Tap Create / Send Invite
-----------------------------
[Press Enter to continue]

After you press Enter the script resumes. For UI-only verifications (e.g. "does Amethyst show reaction 🌮?"), the script asks:

? Does Amethyst show the 🌮 reaction?  [p]ass / [f]ail / [s]kip:

Pick p, f, or s.

Output

  • state/logs/run-<timestamp>.log — every step, assertion, and human prompt, with the exact wn stdout that was parsed.
  • state/results-<timestamp>.tsv — tab-separated test_id \t status \t note lines. Easy to grep.
  • state/run.env — persistent key/value state (npubs, group ids) so you can kill and resume the harness mid-run without losing context.
  • Final summary table on stdout — colored per-test status and totals.

State cleanup

The harness leaves state/ on disk so daemons and identities survive across runs. To start completely fresh:

# stops daemons if still running; removes identities, groups, logs
./marmot-interop.sh --no-build   # Ctrl-C when it waits for input, then:
rm -rf state/

Published KeyPackages on public relays will remain until they expire naturally or are deleted via wn keys delete-all --confirm. Use a throwaway identity for B/C if this matters to you.

Known gaps

  • Test 10 (concurrent commits) is inherently human-timing sensitive. It's a best-effort race; expect occasional flakes.
  • Test 14 (push) only exercises the harness side — full end-to-end verification requires a running transponder instance and platform registrations that are out of scope here.
  • The harness assumes Amethyst exposes UI affordances for add-member, remove-member, rename, promote/demote, and leave. If any of those is missing from the current build, the corresponding test will fail with a clear note rather than crash.

Files

  • marmot-interop.sh — main entry point; orchestrates preflight, daemons, identities, relays, and runs the 13 tests in sequence.
  • lib.sh — helpers (logging, prompts, polling, jq wrappers, result table).
  • state/ — runtime directory, gitignored. Contains whitenoise-rs/ source checkout, per-daemon data/log dirs, the session run.env, logs, and results TSVs.
