Add the offline Cashu command tier to amy, all driven by the shared
commons wallet code so amy exercises the same path as the Android app:
amy cashu wallet create [--mint URL] [--mints a,b] [--privkey HEX] [--relay r1,r2]
amy cashu wallet show
amy cashu wallet export-key
amy cashu wallet destroy
amy cashu mint ping URL (stateless)
amy cashu mint info URL (stateless)
amy cashu balance [--mint URL]
- create/destroy reuse commons CashuWalletOps.publishWalletEvents /
deleteWallet; show/balance reuse the CashuWalletReader projection over
the local event store; mint ping/info hit quartz's MintHttpClient.
- Context gains cashuOps() (wired to the file NUT-13 counter store + a
per-run seed cache) and cashuSnapshot(); DataDir gains cashu.json.
- Extraction D: CashuKeysetCounterStore contract in commons +
FileCashuKeysetCounterStore (atomic ~/.amy/<account>/cashu.json).
PRs 4 of cli/plans/2026-05-28-cashu-cli.md (extractions A–D + offline
tier). receive/send/maintenance/mint-rec + interop harness still pending.
Verified end-to-end against mint.minibits.cash and live relays.

The framing: Amy gains every cashu action the Amethyst UI exposes, each
one reusing the exact same quartz + commons code the Android wallet
runs in production. The deliverable is a shell harness under
cli/tests/cashu/ that walks two Amy accounts through the full wallet
lifecycle against a production mint, so regressions in the cashu code
path fail on the JVM in CI without an emulator.
Plan covers:
- Three extractions before any verb lands: cashu token parsers to
quartz, CashuWalletOps to commons, CashuWalletReader projection
helpers to commons.
- One storage addition: ~/.amy/<account>/cashu.json for NUT-13 keyset
counters (deterministic secrets need durable counter state across
invocations).
- Command surface under amy cashu …: wallet, mint, balance, receive,
send, mint-rec, maintenance — mirrors every action the Android
wallet exposes.
- Stable --json shape per verb.
- 9-PR sequencing: extractions first, then verbs grouped by user
intent, then the 10-scenario interop harness.
- Acceptance criteria: harness passes against mint.minibits.cash and
the on-relay events are byte-equivalent to what Amethyst would
produce.
Three changes that go together:
1. Reconcile cli/plans/2026-04-24-file-event-store-{overview,nips}.md
with shipped reality: code lives in quartz/jvmMain/, not commons/;
data dir is <data-dir>/events-store/, not <root>/events/.
2. New StoreCommands wired as `amy store …`:
- stat → events count, kind histogram, disk bytes,
oldest/newest createdAt. Pure read, no Context
(skips identity check).
- sweep-expired → wraps store.deleteExpiredEvents(); reports
{swept, remaining}.
- scrub → wraps store.scrub() to rebuild idx/ from
canonicals.
- compact → wraps store.compact() to drop dangling idx/.
All four open the FsEventStore directly (no Context, no identity
needed) — they're store-only operations.
3. New e2e harness at cli/tests/cache/cache-headless.sh that boots a
local nostr-rs-relay, two amy identities (A + B), and asserts:
T1 — store stat reports non-empty store after publish-lists +
profile edit, with kind:0 and kind:10002 present.
T2 — A's `profile show` is `source: "cache"` by default.
T3 — `--refresh` forces `source: "relays"`.
T4 — B's first `profile show <A_NPUB>` is a relay miss; second is
a cache hit (proves drain populates the local store and
subsequent reads serve from disk).
T5 — `relay list` reads URLs back from the local kind:10002 /
10050 / 10051 events.
T6 — relays.json no longer exists in either data-dir.
T7 — store stat / sweep-expired / scrub / compact all run
without an identity present.
Same pattern as cli/tests/dm/dm-interop-headless.sh — reuses the
nostr-rs-relay infrastructure from cli/tests/marmot/setup.sh.
Three-part design doc for an IEventStore backed by a directory tree
instead of SQLite, targeted at the cli/ module.
- overview: goals, directory layout, feature-parity matrix, public API
- pipelines: insert (T1-T8 with crash-safety), query planner, delete,
transactions, concurrency
- nips: replaceable/addressable slot enforcement via hardlinks +
atomic rename, NIP-09 tombstones (hardlink to the kind-5), NIP-40
expirations, NIP-50 FTS via inverted-index hardlinks, NIP-62 vanish
cascade, tag indexing, seed file, scrub/compact, test strategy,
10-step rollout
Design doc for `amy dm send|list|await`, reusing the existing Quartz
gift-wrap (NIP-17/NIP-59/NIP-44) pipeline. Single file under
cli/plans/; extracts FilterGiftWrapsToPubkey from amethyst/ to commons/
as a prerequisite commit so the CLI can depend on it without pulling
in :amethyst.
