Merges nostr proposal 2ca4f8ae into main:
- feat(cli): full NIP-34 git collaboration parity for `amy git`
- feat(cli): `amy git grasp list|set` (NIP-34 GRASP server list, kind 10317)
- feat(cli): `amy git browse|cat|log` — read git objects over smart-HTTP
- feat(cli): `amy git init` — bootstrap a repo from the local git checkout
- feat(cli): `amy git label` (NIP-32) and `amy git apply` (patch -> working tree)
- fix(quartz): NIP-34 wire-format interop with ngit (clone/web, issue p, plain r)

- fix(cli): shallow-clone euc, read truncation, process deadlock
- fix(cli): read routing, status perf, publish-ack + robustness
- fix: complete PR clone multi-value (kinds 1618/1620) + CLI robustness
- revert(amethyst): drop GitStatusIndex auth change; defer to separate proposal
clone/web now serialize as single multi-value tags per NIP-34 (ngit drops
repeated ones) for kinds 30617, 1618 and 1620; readers stay tolerant of the
legacy repeated form.
The GitStatusIndex status-authority guard was reverted before merge: it
authorized against the status event's own `a` tag, which the author controls,
so a forged ["a","30617:<attacker>:x"] defeated it — and unverifiable statuses
were dropped permanently (no re-reduce when the 30617 announcement arrives),
rendering closed issues as open. Refiling as its own proposal.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The isAuthoritative guard added to GitStatusIndex read the repository owner
from the status event's own `a` tag (GitStatusEvent.repositoryAddress() ->
first a tag, no kind filter, no cross-check against the target's repo). That
value is attacker-controlled: a forged kind:1632 carrying
`["a", "30617:<attacker-pubkey>:anything"]` makes `status.pubKey ==
repoAddress.pubKeyHex` pass, so the spoof it meant to block still succeeds.
It also regressed reads: reduceLatestByTarget only re-runs on a new
kind 1630-1633, so a status dropped while the 30617 was uncached stayed
dropped, leaving genuinely-closed items in the Open tab with wrong counts.
Keep this series focused on the quartz + cli NIP-34 parity work. The Android
status-authorization hardening (resolve the repo from the target item, load
the cached 30617, authorize against repo.pubKey + maintainers() + the target
author, and re-reduce when a 30617 arrives) will land as its own proposal.

Addresses review findings from a merge-time audit.
- **Complete the headline multi-value `clone` fix for PRs** (was applied only to
kind:30617). GitPullRequestEvent (1618) and GitPullRequestUpdateEvent (1619)
carry `clone` with the same spec shape but still emitted repeated single-value
tags and read only the first value — so the exact interop bug this branch set
out to kill was still live for PRs, both directions (ngit keeps only the last
repeated tag; we lost every URL after the first from ngit's multi-value tag).
Now both emit one multi-value `["clone", …]` tag and read both forms. Verified
on the wire + GitNip34InteropTest + CLI harness (40 checks).
- **Android git-status spoofing (GitStatusIndex)**: newest-status-wins with no
author check meant anyone could publish a kind-1632 and make someone else's
issue render closed. Now filter statuses to the repository owner (from the
status's own `a` tag), declared maintainers (from the cached announcement), or
the target item's author — matching NIP-34 and the CLI's derivation. Pre-existing
on main; this branch made the CLI/Android divergence visible.
- **CLI robustness**: `git comment`/`git patch` no longer block forever reading
stdin on an interactive TTY (amy is non-interactive — error instead). The local
`git` subprocesses in `git init`/`git apply` now drain stdout on a side thread
under a bounded `waitFor` + `destroyForcibly`, so a wedged git can't hang the
CLI.
Left as a follow-up (cosmetic): GitBrowseCommands.candidateUrls duplicates
GitRepositoryBrowserViewModel's — worth lifting to shared code, not worth the
cross-module coupling here.

Findings from a second review round (two independent reviewers), with fixes:
Read path (git issues/patches/prs/thread):
- **Reads ignored the repo's own relays** (correctness). They queried only the
account outbox/bootstrap (general relays); NIP-34 events live on the repo
announcement's advertised relays (often GRASP/git-specific), which general
relays don't mirror — so `amy git issues <repo>` with no --relay could return
empty. Now fetch the announcement once and read from queryTargets ∪ its
advertised `relays`. Verified live: `git issues`/`git prs` on the amethyst
repo now return real events (and derive `closed`) with NO --relay.
- **O(items × statuses) status rescan** with un-memoized `rootEventId()` reparse
→ pre-group statuses by root id once (O(1) lookup per item).
- **Status query could truncate / exceed relay caps**: statuses are now paged
(`drainAllPages`) and the `#e` id set is chunked to 50 (under the common
~100-value relay filter cap).
- **Latency regression**: capped the list `drainAllPages` idle timeout to 12s
(was the 30s default; `drain` had been 8s).
- **Nondeterministic status on same-second ties** → deterministic id tie-break.
- Reuse the fetched repo for the maintainer set (removes a redundant round-trip).
Write path:
- **`git init` silently reported success when the 30618 state publish failed**
— its ack was dropped. Now surfaced as `state_published_to`/`state_rejected_by`
with a stderr warning on total rejection.
- **`git apply`** feeds stdin as UTF-8 (was JVM default charset — corrupted
non-ASCII patches) and joins the stdin thread in `finally` (no leak on error).
- **`normalizeCloneUrl`** drops the port from `ssh://git@host:port/…` (it was
carried into the https URL, making it unreachable).
- **Delivery fallback** to the account outbox (repo unresolved / no advertised
relays) now warns to stderr instead of reporting silent success.
Known limitation (documented, not fixed): patch-revision-chain status derivation
follows only the root item, and `git thread` shows first-level replies only
(nested trees and 1619 PR-updates are out of scope). 38/38 harness green.

Claude-Session: https://claude.ai/code/session_01UKMaNoK5M2PQKCAxhxWzPr
Findings from a review pass over the git-parity branch, with fixes:
- **`git init` announced a WRONG earliest-unique-commit on shallow clones**
(interop-critical). `git rev-list --max-parents=0 HEAD` returns the shallow
boundary commits, not the true root, so the repo would be announced under a
different cross-fork identity than ngit computes. Now: detect shallow clones
and omit the euc with a warning to pass `--earliest-commit`; on full clones
derive the deterministic `--first-parent` mainline root instead of an
arbitrary `tail -1`.
- **`git issues|patches|prs` silently truncated and mis-derived status** on
active repos: one single-page `drain` pulled items AND status events under a
shared cap, so status events (newer, more numerous) could crowd items out of
the window and the close-status that determines an item's state could fall
outside it → a closed item read as open. Now paginate the items
(`drainAllPages`) and fetch exactly the statuses that `e`-reference them.
Verified on the live amethyst repo: 51 PRs paginated, 19 correctly closed.
- **Pipe-buffer deadlocks** (latent): `GitInitCommand.git()` discards stderr to
the OS (a chatty command can no longer fill its stderr pipe and hang the
stdout read); `GitApplyCommand.runGit()` writes stdin on a background thread
while draining stdout, so a patch larger than the pipe buffer can't deadlock.
- Minor: `git cat` binary detection uses an index loop instead of boxing 8000
bytes; `GitRepositoryEvent.clones()/webs()` dedupe.
The harness `git init` test now runs against a fresh full checkout (this repo's
CI checkout is shallow) and adds a shallow-clone case asserting the euc is
omitted. 38/38.

Adds a `--live` block that reads the actual amethyst repository ngit publishes
to relay.ngit.dev and asserts our reader parses ngit's real multi-value `clone`
tag (currently 4 URLs) plus its published issues. This is the real-world proof
of the multi-value interop fix: the pre-fix reader would have surfaced only the
first clone URL. Opt-in (needs network + the live relay), skipped by default.
Verified manually end-to-end against the live repo: repo announcement (4 clone
URLs), issues (1621), patches (1617), pull requests (1618, with a real `closed`
status derived from ngit's status event), and a NIP-22 comment via `git thread`
all read correctly.

Verified Amethyst's NIP-34 events byte-for-byte against the ngit reference
implementation (DanConwayDev/ngit-cli) and the spec, and fixed three real
interop divergences in quartz — so ngit/gitworkshop and Amethyst read each
other's git repos, issues, patches, and PRs without losing data.
- Repository announcement `clone`/`web` were emitted as REPEATED single-value
tags (`["clone", a]`, `["clone", b]`). The spec and ngit use ONE multi-value
tag (`["clone", a, b]`), and ngit's parser keeps only the LAST of repeated
known tags — so multi-URL repos silently lost every URL but one in both
directions. Now emitted as a single multi-value tag; `clones()`/`webs()` read
BOTH the spec form and the legacy repeated form, so old events still parse.
(`relays`/`maintainers` were already correct multi-value tags.)
- Issues (kind 1621) were missing the `["p", <repo-owner>]` tag that patches and
PRs already include — a maintainer watching `#p` wouldn't see them. The
builder now adds it (fixes both the CLI and the Android issue-creation path,
which both passed an empty notify list).
- Patch / PR / PR-update `r` tags carried the `"euc"` marker
(`["r", commit, "euc"]`). Per the spec and ngit that marker belongs only on
the kind-30617 announcement; other `r` tags are plain `["r", commit]`. A `#r`
filter matches either shape, so this is a spec-compliance/byte-parity fix.
`alt` (NIP-31) tags are intentionally still omitted — quartz treats the generic
alt client-hint as deprecated, and ngit/gitworkshop parse the structured tags,
so it isn't required for interop.
Adds `GitNip34InteropTest` (5 cases: multi-value write, tolerant read of both
forms, issue p-tag, plain patch r-tag) and 4 wire-format assertions to the CLI
git harness (37 offline). No regressions in the nip34 or Search suites.

Close two more ngit/nak parity gaps:
- `git label TARGET LABEL[,LABEL]` — attach NIP-32 kind:1985 labels to an
issue/patch/PR (the `ngit pr label` / `issue label` surface), over quartz's
existing `LabelEvent`. Namespace defaults to `ugc`; `--namespace` overrides.
- `git apply PATCH_ID` — fetch a kind:1617 patch and apply it to the local
working tree via `git am` (the `nak git patch apply` / `ngit pr apply`
surface); `--check` dry-runs `git apply --check`, `--print` emits the patch.
Shells out to `git` like `git init`, since it operates on the local checkout.
Verified end-to-end: a patch published to a relay, fetched, and `git am`'d as a
real commit into a scratch repo; labels land as kind 1985. The harness gains 5
assertions (label + a full publish→apply round-trip), now 33 offline.
Remaining out-of-scope items are documented: git-packfile push (needs a git
write layer quartz lacks) and NIP-34 cover notes (kind 1624, no quartz builder).

Match `ngit init` / `nak git init`: read the local git repository and publish a
NIP-34 repository announcement, deriving the fields instead of making the user
type them. Shells out to `git` to determine the name (top-level dir), clone URL
(origin remote, ssh→https normalized), earliest-unique-commit (root commit),
and — for the accompanying kind:30618 state — the branch/tag tips and HEAD.
Publishes the 30617 announcement and (unless `--no-state`) the 30618 state in
one shot. Every derived value is overridable with a flag; outside a git repo
the derivation is skipped and `--name`/`--clone` are supplied manually.
This is the one `amy git` verb that shells out to `git`, since it is inherently
about the local working tree — exactly like the tools it mirrors.
Verified against the amethyst checkout itself (derives name=amethyst, the origin
clone URL, the root commit as EUC, and a 30618 with the live branches + HEAD).
The harness gains 4 assertions driving `git init` against its own checkout.

Give `amy git` the git-object read side of `nak git download` / a shallow
clone. `browse` lists a repo's tree, `cat` prints (or `--out` writes) a file at
a ref, and `log` shows recent commit history — all over the git smart-HTTP v2
protocol via quartz's `GitHttpClient` (the same shallow-clone path the Android
repo browser uses). REPO may be a NIP-34 coordinate/naddr (whose announcement
supplies the clone URL) or a raw http(s) clone URL; `--clone` and `--ref`
override the URL and branch/tag.
Read-only: pushing git objects back to clone/GRASP servers stays out of scope.
Verified live against a public repo (octocat/Hello-World) — browse/cat/log all
return correct trees, blobs, and history. The harness gains a `--live` block
(28 assertions with `--live`, 24 in the default offline run) exercising these
against `$LIVE_REPO`, skipped by default since it needs a reachable git host.

Extend `amy git` from repo announce/list/show/issue to the complete
pure-Nostr surface of `ngit` and `nak git`, so every NIP-34 collaboration
flow is scriptable without a GUI.
New sub-verbs (all thin assembly over quartz's `nip34Git` builders):
- `git state` — kind:30618 repository state (branch/tag tips + HEAD)
- `git patch` — kind:1617 patch from `git format-patch` (--file or stdin),
with --root/--root-revision, --commit, --parent-commit,
and --in-reply-to for revision chains
- `git pr` / `git pr-update` — kind:1618 pull request + kind:1619 tip update
- `git comment` — NIP-22 kind:1111 reply on an issue/patch/PR/repo (the
modern replacement for the deprecated kind:1622 git reply)
- `git open|applied|close|draft` — kind:1630/1631/1632/1633 status events
(aliases `merged`/`resolved` for applied); applied carries
--merge-commit / --commit / --patch
- `git issues|patches|prs` — list a repo's items with status derived from the
newest authoritative (owner/maintainer/author) status event,
with --open/--applied/--closed/--draft/--status filters
- `git thread` — one item plus its status timeline and comments
Shared parsing/fetch/routing glue lives in `GitSupport`; the existing
announce/list/show/issue verbs now reuse it. The git *packfile* transport
(clone/fetch/push of real objects to clone/GRASP servers) stays out of
scope — it needs a git plumbing layer, not an event builder — and is
documented as such.
Adds `cli/tests/git/git-nip34-headless.sh` (21 assertions, drives the whole
flow against `amy serve` and checks the status-deriving reads) and updates
the README/ROADMAP command tables.

Bring the notifications-pagination feature up to date with main.
Conflict resolution — the two live-notification managers:
main independently fixed the "notifications capped at a week" bug by a
different route: it dropped the oneWeekAgo() floor and now runs an all-time
`#p`+`limit` query gated by the lastNoteCreatedAtIfFilled() paging boundary
(kept together with its lastNoteCreatedAtWhenFullyLoaded collector job). That
updateFilter + newSub pair is one self-consistent unit, so this merge takes
main's complete version of AccountNotificationsEoseFrom{Inbox,Random}
RelaysManager and keeps the branch's dedicated `until`+`limit` history pager as
an additive layer on top (Account.notificationHistory, the history manager,
NotificationHistoryPaging.kt, the markers/retry UI, filter builders, tests).
Net: the feed gets main's all-time live query plus the branch's unbounded
backward pager. Note the two now overlap for users under the relay limit — the
pager's remaining unique value is scrolling past that limit; worth a review
pass, not a merge blocker.
Verified: :amethyst:compilePlayDebugKotlin, spotlessApply (clean), and the
notification unit tests (FilterNotificationsHistoryTest,
NotificationKindsContractTest) all green on the merged tree.

CardFeedView had grown a ~90-line paging block plus an auto-retry loop,
constants and helpers that aren't about rendering cards. Move all of it into
a dedicated NotificationHistoryPaging.kt:
- rememberNotificationHistoryPaging(): the look-ahead buffer driver (with the
per-burst cap), the stalled-relay auto-retry loop, cursor building, and the
per-relay sentinels — returns the List<RelayReachCursor> the feed draws.
- BootstrapNotificationHistoryWhenEmpty(): the empty-feed hunt.
- The five tuning constants and the reachState / relayShortName helpers.
CardFeedView.FeedLoaded now just fetches the pager, calls the helper for the
cursors, and renders the detail dialog; the in-gap RelayReachMarkers stay
inline (they're per-row). No behavior change.

Address the two audit findings on the infinite-scroll driver.
- Bound the eager fill (#1): the buffer targets 100 rows but pages are pulled
in events and notifications collapse heavily into cards, so on a dense
account a fill could keep pulling until it downloaded the whole history to
reach the row target. Cap consecutive pages pulled WITHOUT scrolling
(NOTIFICATION_MAX_PAGES_PER_BURST); scrolling resets the budget, so paging
resumes as the buffer is consumed. Appended older cards don't move
firstVisibleItemIndex, so the from-top preload still fills the full
look-ahead on open — only a dense whale is bounded.
- Only the active feed drives (#2): add drivesPaging (default true); the split
screen passes page == pagerState.currentPage so an off-screen tab composed
during a swipe no longer drives the shared account pager, and its buffer
driver / auto-retry loop / sentinels stay idle. Single screen and side panel
keep driving.

Improve the notifications history UX around slow/unreachable relays, keeping
the per-relay markers (they let users notice their own bad relays) but making
recovery automatic and the tap-through actionable.
- Auto-retry stalled relays with backoff (~3s→30s): once the buffer driver
stops (every relay done-or-stalled) but some are merely stalled, keep
re-advancing them so recovery no longer depends on the user scrolling to the
marker or reopening the screen. One non-restarting effect so the backoff
survives the transient in-flight blips each retry causes; cancels on leave.
- Add a "Try Again" action to RelayReachDetailDialog (shared): when a caller
passes onRetry and a relay is stalled, the tapped marker's detail popup
offers an active retry and drops the now-inaccurate "retries on reopen" hint.
Notifications wire it to advanceAll; DM callers pass nothing (unchanged).

The buffer-only driver stopped paging once every relay was done-or-stalled
(exhausted), so a transient all-relays blip halted history until re-navigation
— bad for faulty relays with different datasets, exactly when we'd miss data.
Restore the per-relay RelayReachSentinels alongside the look-ahead buffer:
- the buffer driver (advanceAll) keeps the runway full from healthy relays;
- the sentinels retry an individual relay when its frontier marker scrolls
into view — the recovery path once the buffer can't keep the frontier ahead
(relays stalled/exhausted), naturally rate-limited by scrolling.
The buffer keeps the frontier ~a screen below the fold, so the sentinels stay
quiet during normal scrolling and only fire on stall/end. This also makes the
kept per-relay markers functional again (they drive the retry) instead of
purely decorative.

Switch the notifications feed from marker-visibility paging (load only when
the bottom marker is on screen) to infinite scroll: keep ~100 already-loaded
rows below the viewport so the user practically never reaches the end.
- Replace RelayReachSentinels with a buffer-depth driver: when fewer than
NOTIFICATION_LOOKAHEAD_BUFFER (100) rows remain ahead of the last visible
one, step every not-done relay one older page (advanceAll). It re-fires as
each page settles until the buffer refills or all relays run dry — the
wallet's lastVisibleIndex >= totalItems - N pattern with a large N.
- Keep the per-relay BackwardRelayPager engine, cursors and filters unchanged.
- Keep the in-feed per-relay progress markers + tap-through detail dialog;
they are now purely visual (loading is driven by the buffer, not by them).

Closes the privilege escalation: any BAN holder could ban the authorities above
them — including the owner — because the Banlist gate checked only the BAN bit.
Once banned, a member loses all authority (`hasPermission` is `!isBanned && ..`)
and honest clients drop their events, so a single edition from the most junior
moderator permanently silenced every admin above them.
CORD-04 §3 requires the rank half: "One hard rule binds every action: the actor
must hold the required bit and strictly outrank its target — equal cannot act on
equal (an admin cannot ban a peer admin)", restated as §5 step 3. Only §4, which
defines the Banlist, states the bit half alone — which is why both this client
and Armada shipped the same rank-blind gate.
§3 is stated per TARGET while the Banlist is one whole-list document, so it is
enforced as a DELTA rule: an edition may only add or remove npubs its signer
strictly outranks, judged against the roster settled behind it; the owner is
never a valid target (position 0 is "supreme and unremovable"); and entries the
signer may not act on are IGNORED rather than rejecting the edition, so one bad
entry cannot discard the bulk-ban §4 recommends as the collision remedy, and a
rogue cannot grief the list by forcing rejections.
ConcordModeration.currentBanned now reads the honored banlist through the
resolver instead of decoding the raw head. Besides picking up the fork healing
it was missing, this closes a laundering path: our own next ban/unban would
otherwise re-publish an entry our fold refuses, under our signature.
BREAKING (consensus): Armada has not shipped this rule, so banlists can differ
between clients until it does — we now ignore a ban Armada honors whenever the
signer did not outrank the target. Shipping the spec-conformant behaviour was
judged better than continuing to honor an escalation. Write-up to send upstream
is docs/concord-banlist-rank-conformance.md.
The three tests added in 0ae6bc6698 as @Ignore-d documentation now pass and are
un-ignored; two companions (a moderator still bans a plain member, the owner
still bans anyone) passed throughout and pin what the fix had to preserve.
Full :quartz:jvmTest and :commons:jvmTest suites green.
Still open and documented, not addressed here: a banned BAN holder can lift
their own ban (a fixpoint-ordering question that needs a spec ruling), and a
forked ban survives an unban that does not chain onto it.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Correcting the previous commit's reasoning. It concluded from the two
implementations that CORD-04 does not rank-gate the Banlist and that enforcing
it would be a unilateral divergence. Reading the actual spec
(github.com/concord-protocol/concord, not in the Armada repo) shows the
opposite: §3 is normative and binds "every action" — "the actor must hold the
required bit and strictly outrank its target — equal cannot act on equal (an
admin cannot ban a peer admin)" — and §5 step 3 restates it. Banning is the
example the rule itself picks.
Only §4, the section defining the Banlist, states the bit half alone. Both
independent implementations read §4 in isolation and made the same mistake,
which is evidence about the section rather than about the readers.
So the fold fix is spec-mandated. It remains consensus-affecting (we would
ignore bans Armada honors until they ship), so it wants coordination rather
than a race, and the fold is still unchanged here.
Adds docs/concord-banlist-rank-conformance.md to share upstream: verbatim spec
citations, both implementations' gates, a delta-based rule that makes the
per-target requirement expressible against a whole-list entity, and two further
reproduced findings — a banned BAN-holder can lift their own ban (so bans do
not stick against any BAN holder), and a forked ban survives an unban that does
not chain onto it.

Ban/Remove were offered to any BAN holder against any non-owner, ignoring rank
— unlike the role picker, which routes through `canActOn`. Both the Members
roster and the message-level path (`Account.concordBanTarget`, the chokepoint
for the quick-action menu, the note dropdown, the note action sections and the
chat action sheet) now require `canActOn(me, target, BAN)`.
This is NOT the no-op it first looked like. The premise that the fold would
drop such a ban is wrong, and a test proves it: BANLIST is a single whole-list
entity, so `authorizedHeads`/`banGate` gate on the author's BAN bit alone and
never rank-check the list's *contents*. A rank-5 moderator's ban of a rank-1
admin is therefore ACCEPTED by every client, and the admin then loses every
permission, since `hasPermission` is `!isBanned && ..`. It is privilege
escalation, not a silent no-op.
The fold is deliberately left alone. Armada has the identical gap — its
`banlistGate` calls the rank-blind `isAuthorized(.., Permissions.BAN)` while
its role path uses the rank-aware `canActOnPosition` — so rank-gating our fold
would make us ignore bans every other client honors, splitting the banlist
across clients. Closing it needs a spec change, like CORD-05. Refusing to
AUTHOR such a ban restricts only what we write, never what we accept, so it
cannot diverge consensus.
Three `@Ignore`-d tests in AuthorityResolverTest state the fold-level invariant
and currently fail by design; two companions assert the gate does not
over-correct (a moderator still bans a plain member; the owner still bans
anyone). Un-ignore the first three when the spec closes the gap.
The owner short-circuits the check rather than going through `canActOn`, which
begins at `hasPermission` and is false while banned — since a rogue BAN holder
*can* currently banlist the owner, routing them through it would let them be
locked out of moderating their own community.
Device-verified on Amethyst QA Concord as Dr. Edo (QA Lead, rank 2): Bob
(Admin, rank 1) now offers only the disabled "Roles… / You don't outrank this
member" where Ban and Remove used to be enabled, while the Helper (rank 5)
still offers Roles…, Ban and Remove.

Notifications were pinned to the recent week with no way to scroll further
back. Mirror the NIP-04 / gift-wrap DM approach: a backward, per-relay
until+limit pager driven by in-feed window-limit markers that pull the next
older page only while visible.
- Add Account.notificationHistory (RelayLoadingCursors) and
AccountNotificationsHistoryEoseManager, a BackwardRelayPager over the
inbox + NIP-29 group-host relays, registered always-on in
AccountFilterAssembler. It parks until a marker advances a relay.
- Add filterNotificationsHistoryToPubkey / filterGroupNotificationsHistoryToPubkey
and AllNotificationKinds: one combined-kinds filter per relay so the single
per-relay cursor stays gap-proof (empty page + EOSE = nothing older).
- Wire RelayReachMarkers + RelayReachSentinels into the notifications card
feed (CardFeedView), with an empty-feed bootstrap, so scrolling a relay's
marker into view loads more.
- Fix the two live notification loaders to a fixed one-week tail (drop the
fullness-driven `since` drift), letting the marker-driven pager cleanly own
everything older — the same live-tail/history split DMs use.

Adds the Notifications and Concord role-grant rows to the coverage table,
retires the "grantConcordRole is unreachable" finding, and records two new
ones: the Members roster offering Ban/Remove on members the viewer doesn't
outrank (silently dropped on fold), and notification cards whose target note
isn't cached rendering as placeholders.
Also adds the pattern worth carrying forward: a paging boundary gated on a
full page deadlocks against a narrow query window, and the empty state is
self-sustaining.

`Account.grantConcordRole` had been implemented with zero callers, so role
grants were unreachable from the app while the changelog claimed they ship.
This adds the missing surface: a "Roles…" item beside "Make admin" opening a
multi-select over the roles the viewer may hand out.
Both rank rules are enforced by delegating to `AuthorityResolver` rather than
reimplementing them:
- assignable roles are `roles().filter { myRank < it.position }` — the fold
drops a grant whose granter does not strictly outrank every assigned role, so
offering one at or above our own position would publish an edition that every
client then silently discards;
- reachable members are `authority.canActOn(me, target, MANAGE_ROLES)`, which
already folds the whole rule (hold the bit, not banned, target isn't the
owner, strictly outrank) and makes self-promotion fall out for free.
Out-of-reach members show the item disabled *with a reason* instead of omitting
it, so there is no silently no-op control.
The grant REPLACES a member's role set rather than merging into it, so the
dialog preselects their current roles. That preselection is provably complete:
a member's rank is the lowest position they hold, and the dialog only opens
when we strictly outrank that rank, so every role they hold sits strictly below
us and is therefore rendered — no held role can be silently stripped.
`amy concord roles` also gained a `grants:` section reading the post-fixpoint
`authority.roleHolders()`. It previously printed role *definitions* but never
the *grants*, which made the fold outcome unverifiable from the CLI; a
rank-violating grant now shows up as visibly absent rather than as if it landed.
Device-verified on a test community (Admin/QA Lead/Helper/Greeter): the picker
hides roles above the viewer, disables on members who outrank them, preselects
correctly, and a saved grant survived the fold and a fresh relay drain read
back from a second client.

The notifications query pinned `since` to `oneWeekAgo()` whenever it had no
EOSE timestamp. Combined with two other facts that produced a deadlock:
- the EOSE `since` map is in-memory only (`SincePerRelayMap = MutableMap<..>`),
so EVERY cold start re-pinned the window to 7 days; and
- the backward-paging escape hatch (`lastNoteCreatedAtIfFilled()`) only arms
once the feed holds a FULL page (`notes.size >= localFilter.limit()`).
The feed could not fill a page because the query only asked for a week, and the
query could not widen because the feed never filled. Any account whose last
inbound mention was older than 7 days saw a near-empty Notifications tab
forever — including a fresh install of a long-established account.
Worse, the floor was applied to `filterSummaryNotificationsToPubkey` (kinds
1/7/6/9735 — the overwhelming bulk of notifications), which was not even wired
to the paging fallback that the secondary per-key kinds received.
Home is the precedent and does not do this: `filterHomePostsByAllFollows`
passes `since ?: boundary`, i.e. plain null on a cold start, relying on the
relay-side `limit` to bound the response. Notifications was the outlier. These
filters are `#p`-scoped to the user's own key and carry a `limit`
(2000/500/200/20), so an all-time query is one index scan returning at most
`limit` events newest-first — same cost, strictly more useful.
Measured on the test account before the fix: 163 events p-tagging it exist on
relays and are fetchable (100 kind-1 and 100 kind-7, both hitting the query
cap), 77 of which clear the follow gate — yet the tab rendered ~3, because the
account's most recent inbound activity was a month old. After the fix the tab
scrolls back through Feb 2025.

The 30 fixes from this session each carry their reasoning in their own
commit message, and the regression tests are in the repo. What none of
that captures is the shape of the testing itself: what was actually
exercised, what was not, what we knowingly left broken, and how to
reproduce the setups. That lived only in one conversation.
Records four things:
- **Coverage**, honestly split three ways: exercised on device; fixed but
only unit-verified (roughly half the session's work, including the
entire Concord authority chain); and never opened at all (Nests,
Marmot, the whole Desktop app, payments, notifications). Plus the
platform gaps — one tablet, one flavour, one ABI, Android 14 only while
targetSdk is 37, and no real `release` build.
- **Open findings** we chose not to fix, so they are decisions rather
than oversights: the unbumped versionCode, the Firebase scheduling
failure that may cost Crashlytics, Tor settings needing a restart, an
unreachable relay reported as empty, WebView profiles surviving logout,
control-plane edits still dropping unknown keys, and the CORD-05
root-binding gap that Armada shares and therefore needs a spec
conversation.
- **Setup recipes** that took real time to work out: isolating `amy` by
`$HOME`, which relays actually accept a NIP-29 create, deep-linking
past a 1000-entry directory, and proving "no network before consent" by
running a local relay over `adb reverse` and counting events either
side of the tap.
- **Patterns** that recurred often enough to be process problems: tests
that assert the bug, implemented-but-unreachable capabilities, Gradle
serving a stale up-to-date test run and reporting success for a
deliberately broken build, and four confident diagnoses that
measurement overturned.
Written for whoever picks this up next, including the parts that reflect
badly on the testing rather than only the parts that reflect well.

Two StrictMode disk violations on startup and on IPC, fixed differently
because they are different problems.
**Favicon storage was writing on the IPC handler thread**, i.e. the main
looper: `BrowserIconRegistry.record` did `File.writeBytes` inline, and
`init` scanned the directory with `listFiles`. Both now run on an IO
scope. The directory is still published synchronously so `iconModelFor`
and `record` work immediately — only the scan and the write are deferred.
`keys` updates after the bytes are actually on disk, so a reader is never
told an icon exists before the file backing it does, and until the scan
lands an icon renders its placeholder for a frame and then recomposes,
which is what the StateFlow is for.
**The settings read was left synchronous on purpose, and stays that
way.** `notificationServiceEnabled` reads SharedPreferences inside a lazy
initialiser; the surrounding comments record why it is not hydrated
asynchronously — an async hydrate reopens a window where a late disk read
clobbers a user's toggle. Converting it would have looked like a
StrictMode cleanup while resurrecting a settings-corruption bug. Instead
the prefs file is warmed on an IO thread at startup, so the first
synchronous read hits SharedPreferences' in-memory cache. Best-effort by
design: if a main-thread reader wins the race it pays the disk hit once,
exactly as before, and correctness is unchanged either way.
Verified on device: `notificationServiceEnabled` StrictMode hits went
from 9 to 0 on a cold start, no icon storage failures, 884 ms cold start,
no crashes — and both pinned web-app icons (ditto.pub and Brainstorm)
still render, which is the thing making the write async could plausibly
have broken.

A pinned web app showed a generic placeholder instead of its icon —
ditto.pub failed while brainstorm.nosfabrica.com worked. The
discriminator is what each site declares:
brainstorm: favicon.svg AND favicon.png <- the PNG is why it works
ditto: logo.svg only (+ an apple-touch-icon nobody read)
Icons were captured solely through `WebChromeClient.onReceivedIcon`,
which hands back a rasterized Bitmap. Android WebView does not decode SVG
favicons into that callback, so a site offering a raster alternative gets
picked up and an SVG-only site never fires it at all: nothing is
recorded, `iconModelFor()` returns null forever, and it fails silently —
no error, no log line, just a permanently generic icon. SVG-only
declarations are increasingly the norm, so this was set to affect more
apps over time.
Adds a sniffer that, after a main-frame load, ranks the page's declared
icons (raster `rel="icon"` → SVG `rel="icon"` → apple-touch-icon →
/favicon.ico) and fetches the best one IN PAGE CONTEXT, falling through
on failure. The bytes are size-bounded and magic-byte validated before
being relayed down the existing record path; anything unrecognised is
dropped.
Fetching in page context is the point, not an implementation detail. The
registry captures from the WebView deliberately — "an alternative to the
main app fetching host/favicon.ico itself, which would bypass Tor and
leak the request". Ditto's /favicon.ico exists and returns a valid icon,
so fetching it from the app would have been the easy fix and the wrong
one. Every byte still comes through the sandbox WebView's own network
path.
No rasterisation needed: coil3's SVG decoder is registered on the
singleton loader and sniffs by content rather than extension, so stored
SVG bytes decode even under the registry's .png filename. Only a leading
BOM/whitespace trim was required so byte 0 is the '<' the sniffer wants.
Also fixes a second gap found while diagnosing: `NappletBrowserService` —
the EMBEDDED path backing pinned bottom-nav tabs — had no icon capture at
all, so a pinned app's icon depended on having once opened it full
screen. It now gets both the missing raster callback and the sniff.
`NappletHostService` deliberately left alone: it serves verified blobs
over a synthetic internal host, and applet icons already come from the
manifest, so capture there would be dead code.
The sniff runs after a delay and skips when the raster callback already
claimed the host, so sites that worked before are untouched.
Verified on device: ditto.pub now shows its real icon on the favorite
card, the pinned sidebar tab and the recents row, via both the embedded
and full-screen paths; Brainstorm is unchanged; example.com (no usable
icon) degrades to the placeholder with zero record calls and no hang; no
crashes.
Pre-existing, not fixed: `BrowserIconRegistry.record` writes the file on
the IPC handler thread, tripping StrictMode. It did so before this change
— which now simply gives it more occasions. Moving that write off-main is
a cheap follow-up.

Changing an app to PARANOID did not stop it signing. `sessionAllows` is
consulted BEFORE `signerLedger.decide()`, so a live "allow for this
session" grant short-circuits exactly the check the stricter policy would
have failed. The user picks "I'm a bit paranoid", the UI updates, and the
app carries on signing on the strength of a grant made under the old
policy — until every applet surface closes.
The trust level is a decision about how an app is treated from now on, so
the policy change now drops what that app is currently holding, the same
way revoking and forgetting already do. It fires on any change rather
than only on tightening: loosening is the user's call too, and a stale
grant surviving a deliberate re-decision is surprising in either
direction.
Completes the revocation work — the three paths that change what an app
may do (forget, per-op revoke, trust level) now all clear its live
session grants.
Not automatically tested: this is a Compose click handler and `amethyst`
has no Robolectric. The underlying `revokeSessionGrants` is covered by
`revokingAnAppDropsItsLiveSessionSignerGrants`, which was verified to
fail before its namespacing fix.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Three defects, each of which made revocation look like it worked.
**`revokeSessionGrants` had no callers.** It was added with the KDoc "so
revoking an app takes effect immediately instead of lingering until this
broker instance dies" and then never wired, so revoking an app in
Connected Apps left its in-memory session grants active. The user
revokes; the app keeps signing.
**And it was broken as written.** `sessionAllows` keys are the
account-namespaced `napplet:<signer>:<coordinate>|<op>`, but every revoke
call site holds the BARE coordinate, so the prefix match found nothing.
Wiring it naively would have looked correct and silently done nothing. It
now namespaces before matching, and also clears the post-Cancel re-prompt
cooldown so a revoked app prompts on next use instead of being quietly
dropped.
**Worse: there were three ledgers.** `NappletBrokerService`,
`ConnectedAppsScreen` and `ConnectedAppDetailScreen` each constructed
their own `NappletPermissionLedger`, while ALLOW_SESSION grants are
per-instance in-memory state. So "Forget" cleared the screen's own
always-empty session map while the grants the broker actually consults
lived on. The KDoc described a process-wide singleton; it wasn't one.
Promoted to a real singleton in AppModules alongside the existing
permission store, and shared by all three.
The screens are plain composables with no binder to the broker service,
so rather than invent an IPC path the cached broker moved to the
service's companion under a lock — matching the sibling main-process
registries in that package. Both revoke paths call it: the Forget button
and the per-op revoke.
Also gives `NappletPermissionLedger.endSession()` its first caller, which
promoting the ledger made necessary: it used to die with the service, so
session grants had a natural bound. Now that it outlives the service,
`onDestroy` restores exactly the lifetime ALLOW_SESSION already implied.
The boundary is safe — the service is bind-only and is destroyed only
once every applet and browser surface has unbound, so switching between
two open applets never drops grants mid-use. Deliberately NOT wired to
account switch (already handled by account-keying) or to backgrounding
(would re-prompt mid-use).
Test notes, kept honest: the revoke test was verified to fail before the
namespacing fix. The `endSession` test PASSES without the change —
`endSession` itself was always correct, the bug was that nobody called
it — so it is characterization for the new lifetime contract, not a
regression test. The `onDestroy` wiring and the composable click handlers
have no automated coverage; `amethyst` has no Robolectric and no harness
was invented for them.
Known gap, left alone deliberately: changing an app's trust level to
PARANOID does not drop its live session grants, because `sessionAllows`
is consulted before the signer ledger. That is a revoke-shaped action and
belongs in the same fix, but it is a behaviour change and was out of
scope tonight.

An unauthorized control edition in the middle of an entity's chain
permanently froze that entity. Observed on device for a member's GRANT:
v0 owner (grant mods)
v1 owner (grant admins) <- fold stopped here, forever
v2 MIDTIER (escalation, correctly rejected)
v3,v4,v5 owner orphaned, unreachable
`AuthorityResolver` filtered unauthorized editions out BEFORE calling
`EditionFold.foldEntity`, and the walk only advances when the next
version cites the current head's hash. Removing v2 severed the chain, so
every honest edition above it was lost. Any member could permanently
freeze any member's role assignment — including the owner's ability to
change it — with a single event, recoverable only by a Refounding. It
predates the recent rank gates (verified with a zero-role identity); the
gates only widen which editions can poison.
Armada does not have this bug, and its approach settles the design.
Reading its control-plane fold (read for semantics only — Armada is
AGPLv3, Amethyst is MIT, no code taken): the chain walk runs over the
UNFILTERED set, producing an ordered candidate list — chain-verified head
first, then every remaining edition version-descending — and authority is
applied AFTERWARDS, per candidate, picking the first admissible one. A
rejected edition is skipped during the ascending admissibility walk
without truncating it. For the chain above, Armada picks v5.
So the fix is not to filter later but to gate later: `EditionFold` gains
candidate-based gated folding, and the resolver and community state now
gate per candidate instead of pre-filtering the pool. Authority checks
themselves are unchanged — only WHEN they run moved. Applied to ROLE,
GRANT, BANLIST, CHANNEL, METADATA and the authorized-head map.
The writer had to be fixed too, for a sharper reason than expected. With
an ungated `headOf`, a rogue banlist edition at the tip is read as
current state, so the owner's next ban REPUBLISHES THE ROGUE'S CONTENT
UNDER THE OWNER'S SIGNATURE — an unauthorized empty banlist laundered
into an owner-signed one the moment the owner bans anyone else. Tolerant
reading cannot heal that, because the resulting edition is genuinely
authorized. `ConcordModeration.headOf` now folds the authority-gated
heads, and `owner` is a REQUIRED parameter rather than defaulted, since a
silently-wrong default here is a consensus footgun.
Banlist healing is preserved with one necessary change: the ancestry walk
now runs over the full pool rather than the authorized subset. Ancestry is
structural — walking only authorized editions stops at the rejected one
and misreads genuine ancestors as concurrent forks, resurrecting bans an
unban had cleared.
Six regression tests, each verified to fail without the fix. Two process
notes worth recording: the first "without the fix" run reported BUILD
SUCCESSFUL because Gradle served a stale up-to-date `jvmTest` — trusting
it would have meant concluding the tests were worthless. And the
forged-edition test initially passed both ways because the forgery's
content coincided with the honest outcome; it was rewritten so the
mid-chain arm genuinely discriminates.
The rank-gate, rogue-higher-version, floor and rollback tests all pass
unchanged.
Known gap: `headOf` gates through the per-kind permission map, which is
coarser than the resolver's rank gates, so the writer can still pick a
head the reader rejects when an in-permission but out-of-rank edition
sits at the tip. Tolerant reading makes that benign, but it is not an
exact reader/writer match; tightening it needs the resolver to expose
per-entity heads.

`Account.leaveConcordCommunity` has existed since the feature landed and
had ZERO callers anywhere in the repo — so joining a Concord community
was one-way. It stayed in the account's kind-13302 list and in Messages
permanently, with no affordance on the community screen, the Members
screen, or Messages.
Found because a test account joined a probe community whose only relay
then went away: stuck in the list, channels unrecoverable, nothing to
tap. Third capability found this session that is fully implemented and
unreachable, after `ConcordInviteBundle.isExpired` (called only from a
test, so invite expiry was decorative) and
`NappletPermissionLedger.endSession` (never called, so session grants
outlived every revoke). Each made a feature look complete to anyone
reading the model.
Adds "Leave community" to the community screen's top-bar overflow,
mirroring how NIP-29 relay groups already place membership-destroying
actions, behind a confirmation. It renders whether or not the Control
Plane ever folded, which is the case that matters — a dead-relay
community never folds.
The copy is deliberately narrow about what leaving does: it removes the
community from THIS account's list and stops syncing, it does NOT notify
the community or remove anyone from a roster, and returning needs a new
invite.
Owner leaving is allowed, with an extra warning. Blocking it would make
the actual stuck case unfixable, since the motivating community was one
the account created; and it is the user's own private list to edit.
But it is irreversible in a way worth stating: `ownerSalt` lives only in
that entry, so discarding it retires the community rather than
transferring it. Ownership is read from the stored entry rather than the
folded authority, because a dead-relay community has no folded authority.
Works offline by construction: the underlying call rewrites the local
list (falling back to the on-disk backup when nothing folded) and
publishes fire-and-forget to the user's OWN outbox — never the
community's relays — so the UI does not wait on a relay that cannot
answer. Both paths that could resurrect a left entry were checked:
stranded recovery iterates live communities only, and the list import
takes the newest 13302, which is ours.
Tests cover the real logic behind the button — `unfollow` was previously
untested — driven through the offline-backup path with no cached relay
event: drops only the named community, preserves other memberships'
secrets, empties cleanly on the last one, no publish for a community
never joined, and the rewritten list stays self-encrypted.
Not verified on device: building an APK would have replaced the build a
concurrent Concord authority test was running against. The composable
itself has no automated coverage — `amethyst` has no Robolectric.
Two follow-ups noted, not fixed: leaving does not unpin a community from
the bottom bar, so a pinned one leaves a dead tab; and
`grantConcordRole` is another zero-caller capability — the general
CORD-04 role-grant path is unreachable, with only the narrower
make/remove-admin wired up.
