- FsLockManager: cross-process exclusive flock(.lock) with per-thread
re-entry. withWriteLock { body } acquires once on a fresh thread
and reuses on nested calls — so transaction { insert(); insert() }
doesn't self-deadlock.
- FsEventStore: insert / delete / delete(filter) / delete(filters) /
delete(id) / deleteExpiredEvents / transaction now run under
withWriteLock. The `*Locked` helpers expose the lock-free body for
re-entrant callers (transaction body, vanish/deletion cascades,
expiration sweep). close() releases the lock channel.
- scrub(): wipes idx/ and rebuilds every entry from the canonical
events. Slots, tombstones and seed are left alone — slots can pin
data the canonical pass doesn't see, and tombstone removal is a
deliberate "un-forget" per the design plan.
- compact(): drops dangling idx/ entries whose canonical no longer
exists. Cheap — only touches idx/, never opens a JSON.
Tests: 11 new in FsMaintenanceTest covering lock file presence,
transaction commit / propagated exception with kept-prior-events
semantics, re-entrant lock from inside a transaction, scrub
rebuilding idx + FTS after a manual wipe, scrub preserving the
replaceable slot, compact dropping dangling and leaving valid alone,
close idempotence + reopen, and two-thread concurrent insert
serialisation. 97 fs tests green.
Adds idx/fts/<token>/<ts>-<id> hardlinks and an FTS-driven query path.
- FsSearchTokenizer: lowercase + Unicode-aware split on non letter-or-
digit, matching SQLite FTS5's unicode61 default closely enough that
the same call indexes content and parses queries (any drift cancels).
Tokens capped at 100 chars to keep filenames under FS limits.
- FsLayout: idxFts + ftsEntry / ftsTokenDir helpers; skeleton dir.
- FsIndexer.pathsFor: when event implements SearchableEvent, emits one
hardlink per unique tokenised word — so insert/delete maintenance
rides the existing link/unlink path. Eviction (replaceable swap),
NIP-09 cascade and NIP-62 vanish all clean up FTS for free.
- FsQueryPlanner: when filter.search is non-blank, drives by FTS.
Tokenises the query, walks each idx/fts/<token>/ listing into a
HashMap<id, ts>, and intersects smallest-first (AND across tokens —
matching SQLite FTS5 default MATCH semantics). Output sorted by
createdAt DESC. Other Filter fields (kinds, authors, tags, since /
until) still apply via Filter.match post-filter.
Tests: 16 new in FsSearchTest covering tokenizer (whitespace, case,
unicode, punctuation, empty), index maintenance (entries created,
non-searchable kinds skipped, delete unlinks), and query semantics
(single token, AND of tokens, ordering, limit, kind/author compose,
no-match, blank string ignored, reopen). 86 fs tests green.
Adds tombstones/vanish/<owner_hex>.json hardlinks (one per owner,
strongest cutoff wins) plus the cascade and block-future-insert
semantics from SQLite's RightToVanishModule.
- FsLayout: vanishTombstonePath helper + tombstones/vanish/ skeleton.
- FsTombstones: vanishCutoff / installVanish / clearVanish — install
uses atomic rename-with-REPLACE_EXISTING and only proceeds when the
new kind-62's createdAt is strictly greater than any existing tomb.
- FsEventStore:
- constructor now takes optional relay: NormalizedRelayUrl? to scope
NIP-62 cascades (matches SQLiteEventStore's relay arg).
- isBlockedByTombstone now also rejects events whose owner has an
active vanish with createdAt >= event.createdAt — owner is the
recipient for GiftWrap, matching pubkey_owner_hash semantics.
- processVanish() runs after canonical write: skips if !shouldVanish-
From(relay), installs the tombstone, then walks idx/owner/<hex>/
and deletes every event with ts < vanish.createdAt. The vanish
event itself survives (its ts equals the cutoff).
Tests: 11 new in FsVanishTest — relay-scoped cascade, different-relay
no-op, vanishFromEverywhere, block re-insert + newer-passes, equal
ts blocked, other authors unaffected, stronger cutoff wins, weaker
ignored, tombstone shares inode with kind-62 canonical, kind-62 stays
queryable. 70 fs tests green.
Adds idx/expires_at/<padded_exp>-<id> hardlinks for events with an
expiration tag, an injectable clock so tests can drive time
deterministically, and the deleteExpiredEvents() sweep.
- FsLayout: idxExpiresAt + expirationEntry path helper.
- FsIndexer.pathsFor: emits the expiration entry whenever
event.expiration() > 0, so insert / delete maintain it alongside
the kind / author / owner / tag indexes.
- FsEventStore: pre-insert guard rejects events with exp <= now
(SQLite parity: trigger uses inclusive <=). Constructor takes a
clock function defaulting to TimeUtils.now(). deleteExpiredEvents
walks idx/expires_at, parses filenames, and deletes anything with
exp < now (strict <, matching SQLite's sweep query).
Tests: 8 new in FsExpirationTest — future expiration accepted +
indexed, already-expired-on-insert rejected, exp==now rejected on
insert but kept by sweep, non-positive exp ignored, sweep removes
canonical + index entries, plain events untouched. 59 fs tests green.
Tombstone files under tombstones/id/<id>.json and tombstones/addr/
<kind>/<pubkey>/<sha256(d)>.json, each a hardlink to the kind-5
event that authored the deletion. One source of truth: the tombstone
IS the deletion event, just indexed by target.
- FsTombstones — installs id tombstones unconditionally, installs
addr tombstones with strongest-cutoff-wins semantics (later kind-5
replaces earlier via atomic rename), and exposes hasIdTombstone /
addrTombstoneCutoff for pre-insert checks.
- FsEventStore.insert — pre-insert guard: id tombstone always blocks;
addr tombstone blocks when event.createdAt <= tomb.createdAt, matching
SQLite's reject_deleted_events trigger. Kind-5 inserts trigger a
cascade: for each e-tag target owned by the deletion author, unlink
indexes + slot + canonical; for each a-tag (same pubkey), evict the
slot winner if its createdAt <= deletion.createdAt. Tombstones are
installed for every target regardless, so future re-inserts are
blocked.
Tests: 11 new in FsDeletionTest — delete-by-id, block-reinsert-by-id,
non-author-deletion still installs tombstone but no cascade, cascade
addressable slot, newer-at-deleted-address passes, older blocked,
equal-timestamp blocked, later kind-5 raises cutoff, earlier kind-5
does not lower, deletion event stays queryable, tombstone shares
inode with kind-5 canonical. 51 fs tests green.
Brings the file-backed store up to parity with SQLite's ReplaceableModule
and AddressableModule. A slot is a single hardlink that encodes the
UNIQUE(kind, pubkey[, d-tag]) constraint directly in the directory
layout:
replaceable/<kind>/<pubkey>.json (kinds 0, 3, 10000-19999)
addressable/<kind>/<pubkey>/<sha256(dTag)>.json (kinds 30000-39999)
FsSlots handles the full lifecycle: pre-insert guard (reject if newer or
equal exists), atomic rename-with-REPLACE_EXISTING install, and eviction
of the old winner's canonical + index hardlinks. Because the slot is a
hardlink the event data survives external canonical deletion, matching
the "files come and go" contract in the design plan.
delete(id) also clears the slot when the deleted event is the current
winner, so no orphan slot files linger.
Tests: 14 new in FsSlotsTest — newer wins / older rejected / equal
rejected / eviction unlinks old indexes / empty d-tag / canonical-
deletion survives via hardlink / delete-clears-slot / non-replaceable
events never touch the slot dirs. 40 fs tests pass.
The confirmValueChange parameter on rememberSwipeToDismissBoxState is
deprecated — state changes should not be vetoed via callback. Move the
onStartToEnd action to SwipeToDismissBox.onDismiss and rely on
enableDismissFromEndToStart = false to restrict the anchor set.
https://claude.ai/code/session_01CfYsUSGeuBnYsCqa6FDSPk
Hardlink indexes under idx/ and a minimal query planner bring the
file-backed store up to parity with SQLite on filtered lookups.
- FsLayout — path helpers, .seed file (8 random bytes, salts all hashes),
entry filename format <zero-padded ts>-<id>.
- FsIndexer — on insert creates hardlinks at idx/kind/<k>/, idx/author/
<pk>/, idx/owner/<owner_hex>/, idx/tag/<name>/<hash_hex>/. Owner hash
matches SQLite's pubkey_owner_hash (recipient for GiftWrap). Honours
DefaultIndexingStrategy: single-letter tag names only. On delete
unlinks every known path so the inode can be reclaimed.
- FsQueryPlanner — picks a driver (ids / first tag / kinds / authors /
all kinds) and yields candidates sorted by createdAt DESC. Final
predicate check runs through Filter.match so any driver is
correctness-safe.
- FsEventStore — sets mtime to event.createdAt on write, runs queries
through the planner with post-filter, applies limit, dedupes by id
across multi-filter unions, and unlinks indexes on delete.
Tests: 16 new in FsQueryTest covering order, limit, author / kind /
tag drivers, tag OR within a key, tagsAll AND across keys, non-
single-letter-tag behaviour, since/until, count, index hardlink
maintenance, and reopen persistence. All 26 fs tests green.
dm-03 and dm-04 spawn a throwaway "ghost" identity by calling $AMY_BIN
directly (not through amy_a / amy_d), so they missed the plaintext
backend flag added in the previous commit and were failing with
"No TTY and no passphrase source" on headless CI.
https://claude.ai/code/session_01SqdMfLdXvb3GskFLcEj739
First slice of the file-backed IEventStore planned in
cli/plans/2026-04-24-file-event-store-*. Each event is stored as
events/<aa>/<bb>/<id>.json with atomic tmp+rename writes. Ephemeral
kinds are dropped. Duplicate inserts are no-ops (id-level uniqueness).
Staging leftovers are swept on open.
Only id-based query and delete are wired; the query planner, indexes,
replaceable/addressable slots, tombstones, vanish, expiration sweep,
FTS, and transactions land in later steps.
Tests: 10 new tests under quartz jvmTest, all passing.
identity.json previously stored `privKeyHex` and `nsec` as plaintext fields.
0600 file perms keep other OS users out, but not another app running as the
same user — and that is the threat model the CLI actually cares about.
Introduce a SecretStore indirection:
* identity.json now persists only the public parts plus a typed
`secret: IdentitySecret` envelope (keychain | ncryptsec | plaintext).
* macOS uses `/usr/bin/security` (Keychain ACLs bind the item to the binary
that stored it, so other same-user apps need user consent).
* Linux uses `secret-tool` if a Secret Service is running on the session
D-Bus; the gain there is at-rest encryption while the keyring is locked.
* On any platform without a keychain, auto falls back to NIP-49
(scrypt + XChaCha20) with the passphrase read from --passphrase-file,
then $AMY_PASSPHRASE, then a TTY prompt. Another same-user app can read
the blob but cannot decrypt it without the passphrase.
* `--secret-backend=plaintext` is an explicit opt-in for dev scripts and
the interop test harness.
Legacy identity.json files that still carry top-level privKeyHex/nsec are
read transparently and auto-migrate on the next save.
whoami, `create` / `login` existence checks, and init-re-run now use a
metadata-only load path so they do not trigger a keychain prompt or ask
for a passphrase just to echo the npub.
Tests: cli/tests/ setups wire --secret-backend=plaintext through the amy_a
/ amy_d wrappers so headless CI runs do not stall on a TTY passphrase
prompt.

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
Adds a new build-cli matrix to create-release.yml so every tag push also
produces self-contained amy binaries:
- amy-<ver>-macos-x64.tar.gz (macos-13 runner)
- amy-<ver>-macos-arm64.tar.gz (macos-14 runner)
- amy-<ver>-linux-x64.tar.gz (ubuntu-latest)
- amy-<ver>-linux-x64.deb (ubuntu-latest)
- amy-<ver>-linux-x64.rpm (ubuntu-latest)
Each tarball is a flat tree (bin/amy + lib/*.jar + runtime/) with a
jlink'd JDK 21 embedded — no system Java required on the user machine.
The .deb / .rpm install the same tree under /opt/amy/.
Windows is intentionally deferred until cli/ is validated on Windows
(data-dir path handling, file locking on groups/<gid>.mls, identity.json
line endings).
Two follow-ups flagged in comments:
- :commons leaks Compose + Skiko (~40 MB) as transitive deps to :cli.
Tarball lands at ~98 MB instead of the plan's <80 MB target. Size
budget in the workflow is set to 200 MB until :commons is split into
core + ui modules.
- .deb/.rpm install to /opt/amy/bin/amy with no /usr/local/bin symlink.
Users must add to PATH or symlink manually after install.
Wire-up:
- cli/build.gradle.kts gains jlinkRuntime + amyImage (Sync task that
combines installDist output with the jlink runtime + a shell
launcher) + jpackageDeb + jpackageRpm.
- scripts/asset-name.sh gains cli_asset_name() + collect_cli_assets()
alongside the existing desktop collector, preserving the
<product>-<version>-<family>-<arch>.<ext> naming contract.
See cli/plans/2026-04-21-cli-distribution.md for the overall plan.

The release workflow builds its own signed release APKs/AABs and does
not consume the debug outputs. Testers use the Benchmark APK, which is
still built and uploaded. Dropping assembleDebug removes a redundant
APK packaging pass from every PR/main run.
Combining them into a single Gradle invocation caused
:amethyst:packagePlayBenchmark to fail inside AGP's
IncrementalSplitterRunnable worker — both variants share packaging
state in one task graph and the benchmark leg trips on it.
The old workflow always ran these as two separate `./gradlew` calls.
Match that pattern. They still run on the same runner with a warm
Gradle cache, so the compilation savings from sharing quartz/commons
with the test+packageDeb step are preserved; we only pay two Gradle
startups, which is trivial.
identity.json, relays.json, state.json, MLS group state/retained epochs,
keypackage bundles, and the Marmot message archive were written with
default umask — typically world-readable on Unix. On a shared machine
another OS user could read the stored private key or decrypted chat
history.
Introduce SecureFileIO: overwrites go via a sibling tempfile with POSIX
0600 attrs set at creation time and ATOMIC_MOVE into place, directories
are created 0700, and on upgrade DataDir.init tightens any pre-existing
loose files. Non-POSIX filesystems (Windows) fall back to setReadable/
Writable/Executable to strip other-user access.
This is defense against other OS users. Another app running as the same
user is still in scope — the FileStores doc continues to note that real
deployments MUST encrypt at rest.

Previously each OS ran Gradle twice (or three times on Ubuntu): once to
compile+test, then again to build desktop packages, plus a third run on
Ubuntu for Android APKs. Merging these into a single matrix job per OS
lets Gradle build the task graph once and reuse compiled classes across
test, desktop packaging, and Android assembly.
- Combine test + build-desktop into one matrix job (test-and-build)
- Fold build-android into the same Ubuntu matrix leg
- Use --no-daemon consistently; drop the redundant --stop steps
- Raise timeout to 60 min to cover the combined work
Two on-disk layout changes that only affect freshly-created data-dirs (no
migration shim since `amethyst-cli-data` was never tagged or released):
- Default `--data-dir` is now `./amy` instead of `./amethyst-cli-data` —
shorter, matches the binary name, and still overridable via the flag or
`$AMETHYST_CLI_DATA`.
- MLS-only files (`groups/` and `keypackages.bundle`) move under a new
`marmot/` subdirectory so the top-level root stays tidy as more
non-Marmot state lands (notes, profile caches, etc). Existing
top-level files (`identity.json`, `relays.json`, `state.json`) are
unchanged.
README tree diagram and DEVELOPMENT.md test table updated to match.
Moves the top-level `post` and `feed` verbs under a single `notes` group
(`amy notes post`, `amy notes feed`). Keeps the per-event-family grouping
consistent with `profile` (kind:0), `dm` (NIP-17), and `marmot` (MLS).
PostCommand and FeedCommand are unchanged — the new NotesCommands object
is a thin dispatcher that routes `notes post` / `notes feed` into them.
Adds three new top-level verbs to amy that mirror the core social-feed
surface of the Android client:
- `amy profile show [USER]` / `amy profile edit ...` reads and patches the
user's NIP-01 kind:0 metadata. `edit` reuses MetadataEvent.updateFromPast
semantics so unset flags keep prior values and blank values delete the
field, falling back to MetadataEvent.createNew when no kind:0 exists yet.
- `amy post TEXT` publishes a NIP-10 kind:1 short text note to the user's
outbox relays via TextNoteEvent.build.
- `amy feed [--author USER] [--following] [--limit N] [--since|--until TS]`
reads kind:1 notes — own / single-author / contact-list — using
Context.drain with author-scoped filters, dedups by id, and returns the
newest-first window as JSON.
All three keep the thin-assembly-layer rule: no Nostr or business logic in
cli/, every event is built/signed via quartz/ and published through the
existing Context.publish + Context.drain helpers.
The default Event.notifies body was hand-rolling a tag scan for lowercase
`p`, duplicating the tag-shape knowledge that already lives in PTag.
Give PTag ownership of the check:
PTag.isNotifying(tags, userHex) // iterates tags and uses PTag.isTagged
Event.notifies now delegates to it. Kinds that override (CommentEvent,
WakeUpEvent) still work — they compose or replace the default as before.
https://claude.ai/code/session_01GQDJxiHPogdzCNhUBN7Pjc
The notification pipeline previously hard-coded a lowercase-`p`-tag match
in two places (the observer predicate and consumeFromCache via
taggedUserIds). That's correct for most kinds but wrong for two:
- NIP-22 CommentEvent: a comment several levels deep only tags the root
author via uppercase `P` (RootAuthorTag). Pure lowercase-p routing
missed "someone replied deep in your thread" notifications.
- Experimental WakeUpEvent (kind 23903): its `p` tags are the authors of
the subject events it references — Bob reacting to Alice's post yields
a WakeUpEvent with p=Bob, even though Alice's device is the one that
needs to wake up. Transport-layer routing (push/relay subscription)
already delivered the event to the right device, so the in-event
routing has to be permissive.
Introduce `open fun Event.notifies(userHex: HexKey): Boolean` with a
lowercase-`p` default that covers NIP-01/04/17/25/28/34/57/68/71/84/AC/
chess/wiki/long-form/poll mentions. Each kind with distinct semantics
overrides:
- CommentEvent.notifies: super.notifies(u) || rootAuthorKeys().contains(u)
— picks up uppercase P root-author routing on top of lowercase p.
- WakeUpEvent.notifies: true — every logged-in account is a valid wake
target once the event has reached LocalCache on this device.
NotificationDispatcher's observer predicate and EventNotificationConsumer.
consumeFromCache both now ask `event.notifies(accountHex)` instead of
extracting taggedUserIds themselves. The zap path's redundant
isTaggedUser re-check is gone too (it was duplicating what the outer
routing already enforced).
https://claude.ai/code/session_01GQDJxiHPogdzCNhUBN7Pjc
Filter.match is itself just a boolean predicate, so carrying a Filter and
a separate composition predicate on NewEventMatchingFilter duplicated the
abstraction. Collapse to one predicate:
- NewEventMatchingFilter(predicate, onNew): drops the Filter parameter.
- LocalCache.observeNewEvents(predicate): primary API.
- LocalCache.observeNewEvents(filter): kept as a one-liner that forwards
filter::match, so existing feed/DAL callers are unchanged.
In the dispatcher the freshness check, kind check, p-tag match, and
since cutoff now live in a single lambda, short-circuiting on cheap
kind comparison first. NOTIFICATION_KINDS is now a Set<Int> for O(1)
membership instead of O(n) List.contains — cheap, but on a hot path
that runs for every new cache insertion it pays for itself.
