TRIM_MEMORY_UI_HIDDEN fires on every app switch, not only under memory
pressure. Clearing Robohash (CPU-intensive SVG assembly) and
CachedRichTextParser to zero there forces a full rebuild on every
resume, causing visible jank.
Restructure the trim tiers to match Android's intent:
UI_HIDDEN (20) — just backgrounded, no pressure:
trim Coil image cache to 1/2 only; leave parsed-text and
avatar caches warm so resume is instant.
BACKGROUND (40) — mild background pressure:
trim images to 1/4, richtext→100, robohash→20, nip11→200.
MODERATE (60) — system is hurting:
clear images, richtext→50, robohash→10, nip11→100.
COMPLETE (80) — kill imminent:
clear everything including nip11.
Foreground levels (RUNNING_LOW/RUNNING_CRITICAL) are unchanged.

Clearing lastNotes caused the next additive update to call
refreshSuspended(), reloading the full filter limit (~500 notes) from
LocalCache and immediately undoing the trim.
With lastNotes intact the fast additive path stays active: only
genuinely new notifications are appended, so the card list remains near
maxItems until the next full feed key change or navigation event.
The Note refs in lastNotes are the same object instances already held
by LocalCache. They are freed when MemoryTrimmingService prunes
LocalCache and the following refreshSuspended() replaces lastNotes with
the pruned set.

CardFeedContentState.lastNotes holds strong references to every raw Note
that passed the notification filter, used for additive dedup
(filteredNewList.minus(lastNotesCopy)). Trimming only the Card list left
all those Note objects pinned — they couldn't be GC'd even if LocalCache's
SoftCache had evicted them.
Fix: clear lastNotes/lastAccount alongside the Card list truncation.
The next additive update finds lastNotes == null, skips the fast path,
and calls refreshSuspended() — one controlled rebuild from LocalCache
that also resets the dedup set to the current state.

At UI_HIDDEN (fires on every app switch), nip11Cache.trimToSize(0)
was clearing all successfully-fetched NIP-11 relay documents, forcing
10–50 redundant HTTP fetches on the next foreground resume.
- Change UI_HIDDEN trim target from 0→100; the 100 most-recently-used
relay docs are kept across a background/foreground cycle.
- Stop trimming relayInformationEmptyCache in Nip11CachedRetriever:
it holds only lightweight display-name+favicon-url placeholder objects
(no network data), so trimming saves negligible memory but silently
re-triggers NIP-11 HTTP fetches for every relay on resume.

50 was too aggressive — users would lose most of their scroll history on
any critical-pressure event. 200 is a better balance: still releases
~60% of the 500-note strong references per feed while keeping a
reasonable amount of history visible without a reload.
Co-Authored-By: Claude <noreply@anthropic.com>
Feed lists hold ImmutableList<Note> references. At 40+ feeds × 500 notes
each, that's 20k strong Note references that prevent GC from collecting
objects that LocalCache has already pruned. Under RUNNING_CRITICAL the
feeds are shrunk to 50 items, releasing ~19k references per account.
Implementation:
- FeedContentState.trimToSize(maxItems) — truncates the loaded list in-place
- CardFeedContentState.trimToSize(maxItems) — same for notification card feeds
- AccountFeedContentStates.trimFeedsToSize(maxItems) — fans out to all feeds
- AppModules.trimLevelEvents: SharedFlow<Int> — broadcasts the OS level
- AccountFeedContentStates subscribes and calls trimFeedsToSize(50) at
RUNNING_CRITICAL, letting the next scroll/refresh repopulate from cache
Co-Authored-By: Claude <noreply@anthropic.com>
Tier 2 (medium, >= RUNNING_LOW): pruneHiddenEvents + pruneHiddenMessages
— muted/blocked content is known-safe to drop at low pressure.
Tier 3 (critical, >= RUNNING_CRITICAL): pruneOldMessages + pruneRepliesAndReactions
— these are more aggressive since they remove content the user may
still scroll back to, so reserve them for genuine memory emergencies.

cleanObservers() only removes flows not currently held by the UI, so
it carries no visible side effects and is safe to run on every trim
regardless of pressure level. Move it from Tier 3 (RUNNING_CRITICAL)
to Tier 1 (always) so unused observer links are freed even on mild
memory signals.
Co-Authored-By: Claude <noreply@anthropic.com>
MemoryTrimmingService.doTrim() previously ran the full pruning suite
regardless of how severe the OS signal was. Now it tiers the work by
ComponentCallbacks2 level so low-pressure signals don't pay the cost of
aggressive observer teardown:
Tier 1 (always): cleanMemory + pruneExpiredEvents + prunePastVersionsOfReplaceables
Tier 2 (>= RUNNING_LOW): + pruneOldMessages + pruneRepliesAndReactions
Tier 3 (>= RUNNING_CRITICAL): + cleanObservers + pruneHiddenEvents/Messages
The `level` is now threaded from Amethyst.onTrimMemory → AppModules.trim(level)
→ MemoryTrimmingService.run(…, level) → doTrim(…, level). The existing
scheduled-trim call site (AppModules.trim) defaults to RUNNING_CRITICAL so
its behaviour is unchanged.

Mirrors the web-app load-recovery fix to the napplet/nsite path and fixes a
layer bug that kept the overlay from ever showing.
The embedded surface (SandboxedSdkView) is drawn by EmbeddedTabLayer, which
sits *above* the nav screens in the shell. So a loading/error overlay placed in
the favorite screen was covered by the surface's opaque pre-first-frame
background — the black void persisted. Move the overlay into EmbeddedTabLayer,
drawn over the active tab's bounds (where the chrome sheet already lives), so it
actually covers the surface. Also fixes the overlay sizing (fillMaxSize, not
matchParentSize, which collapsed to zero inside the reserved Box).
- Promote load state to the EmbeddedSurfaceController interface (loadStatus /
onLoadStatusChanged / retry), so EmbeddedTabLayer renders one overlay for both
the browser and napplet controllers. Shared EmbeddedLoadStatus +
EmbeddedLoadOverlay.
- NappletHostService now reports main-frame load state (start/finish/error) over
a new MSG_LOAD_STATE; EmbeddedNappletController relays it and exposes retry()
(= reload the verified content).
- The web-app path keeps its about:blank → canonical-URL self-heal; the napplet
path has no client-supplied URL to drop, so retry = reload.
Verified on device: with the network cut, the brainstorm tab shows
"Couldn't load this app." + Retry; restoring the network and tapping Retry loads
the page.

A favorite web app pinned to the bottom bar at runtime could come up on a
blank surface (black, then white after a manual reload) and never recover.
Its warm browser session settled on about:blank — its real URL was dropped on
the way in — and the chrome Reload button calls WebView.reload(), which just
re-loads about:blank instead of the favorite's page.
Fixes:
- The provider now reports main-frame load state (start/finish/error) over a
new MSG_LOAD_STATE. When a favorite session settles on about:blank while it
has a real URL, the controller re-navigates to the canonical URL once.
Gated on a real startUrl, so the generic browser's intentional about:blank
new-tab page is left alone. Adds controller.retry() (navigate-to-canonical,
not reload) for the chrome retry path.
- FavoriteWebAppScreen now draws a loading spinner until a real page paints,
and an error + Retry overlay when the main frame fails or the load stalls
(12s) — so a slow, blank, or failed load is no longer a silent black/white
void.
Scoped to the browser/WebUrl path; the napplet/nsite path is unchanged.

- Pinned web favorites in the bottom navigation now show the captured favicon
instead of the generic globe (falling back to the globe until one is
captured). Resolved via BrowserIconRegistry, same as the launcher cards.
- Each Recent row in the browser home gains a 3-dot overflow menu to add the
URL to favorites (or remove it if already favorited) and to remove it from
history. Replaces the prior long-press-to-remove with a discoverable menu;
the row icon shows a star once the site is favorited.

Builds on the omnibox work to modernize the launcher list now that favorites
and visit history both exist:
- Idle browser home (BrowserHome): pinned favorites on top under a "Favorites"
header, then a "Recent" section from the visit history — all in one grid so
they scroll together. Long-press a recent to drop it.
- Typed suggestions are grouped: a highlighted "Favorites" group first (subtle
primary-container tint + medium weight), then "Recent". Favorites still rank
first via the existing frecency boost.
- Real favicons: captured from the WebView that already loaded the page in the
keyless :napplet browser host (so they ride the page's own Tor-routed network
path — the main app never fetches host/favicon.ico itself), scaled and
relayed as PNG bytes over a new MSG_RECORD_ICON IPC, and stored per-host by
BrowserIconRegistry (main process, filesDir). Favorite cards, suggestion
rows, and recent rows all show them, falling back to a glyph.
FavoriteAppIcon gains an optional iconModel; FavoriteAppCell is reusable via a
new LazyGridScope.favoriteAppItems extension so the browser home and the
Favorite Apps tab share one cell. Thumbnails deferred to a follow-up.

Refines the browser URL-bar experience across the launcher and the in-page
browser chrome:
- Shared URL normalization (commons OmniboxInput): dedupes the logic that was
copied between BrowserScreen and NappletBrowserService, recognizes bare
domains/localhost/IPs, falls back to a (configurable) DuckDuckGo search, and
flags .onion as Tor-only so the launcher forces Tor for it.
- Omnibox suggestions (commons OmniboxSuggestions): ranks favorites + visit
history by prefix/substring match, favorite boost, and frecency; deduped by
host. The launcher body turns into a suggestion list as you type.
- Inline ghost-text completion in the address field (TextFieldValue selection),
completing a typed host fragment to the top-ranked host.
- Visit history (BrowserHistoryRegistry, main process): a device-local,
bounded, DataStore-backed store. Pages are recorded ONLY on a clean
main-frame load — relayed from the keyless :napplet browser host over a new
MSG_RECORD_HISTORY IPC — so misspelled/unresolved addresses never enter it.
- In-page editable address bar (websites only) in NappletControlSheet, showing
the live URL + a security glyph (Tor/https/plain) and loading what the user
types. nsite/napplet hosts pass no navigate callback, so they never get one.
Pure logic is covered by unit tests in commons.

The Browser is reachable both as a bottom-bar tab (top-level, no back arrow)
and from the navigation drawer (pushed onto the back stack). In the latter case
its omnibox now leads with a back arrow that pops, matching the convention the

ArrowBackIcon when nav.canPop(), nothing otherwise.

The embedded surfaces' Compose TopControlSheet and the full-screen activities'
native NappletControlSheet are deliberate twins in different processes/modules
(Compose in the main app vs hand-built Views in the Compose-free :napplet
sandbox host), so they can't share a composable — but they should render
identically. Bring them in line:
- Uniform row rhythm: every action/Tor row now uses the same 10dp vertical
padding in both. The Compose switch row was 6dp while items were 12dp; both
are now 10dp, matching the native rows.
- Native Tor row now uses a real framework Switch as the state indicator (like
the embedded row) instead of an icon whose tint/alpha encoded on/off; the icon
is a steady muted tint and the whole row is the toggle target.

Per NIP-46 (nostr-protocol/nips#2381), client metadata is the 4th
positional connect param. When it is present but the optional secret or
permissions are not, those slots are now back-filled with empty strings
so the metadata always lands at index 3. Parsing maps empty placeholders
back to null. When no metadata is sent, the array stays as short as
possible for backward compatibility.

Sandbox host services (per-session correctness + leaks):
- NappletHostService/NappletBrowserService: guard broker-reply delivery against
a stale tab (drop replies whose session was replaced) and wrap postMessage in
runCatching so a torn-down WebView can't crash the relay; tear down each tab's
content server + WebView on session close and in onDestroy; refuse to build an
orphan WebView for an unknown session.
- NappletContentServer.close(): shut the OkHttp dispatcher + evict the pool off
the hot path so a closed tab doesn't leak connections/threads.
- NappletBlobHttp: bound a blob fetch end-to-end with a callTimeout so a stalled
Tor exit can't pin the WebView worker thread indefinitely.
- UiAdapter close(): hop to the main thread before destroying the WebView.
Embedded IME (shim.js + RemoteImeView):
- Surrogate-pair-safe diff so an edited astral char (emoji, CJK-supplement) is
never split into a lone surrogate in the synthesized InputEvent data.
- Real contenteditable support: map char offsets through Ranges and replace in
place instead of overwriting textContent (which destroyed structure + caret).
- Dedup selectionchange against the last applied selection so our own setSel
doesn't echo back to the host as a fresh edit.
- RemoteImeView flushes synchronously at the outermost batch close, preserving
the composing region across a compose+commit in the same frame.
Embedded layer + preloader:
- Resize the cross-process surface to the snapped imeAnimationTarget instead of
the animated ime inset, so it doesn't reconfigure every keyboard-slide frame.
- yield() between favorites in the startup sweep so building WebViews doesn't
monopolize the frame.
- Per-site Tor/open-web registries expose awaitReady(); the preloader awaits
hydration before its first routing decision so a cold start can't route a
site the user pinned to the open web through Tor.

Mirror the browser host's per-session refactor for the napplet/nsite embed
provider. A single NappletHostService instance is shared by every embedded tab
(same bound Intent), but it kept one set of fields (client messenger, config,
content server, WebView, broker bridge), so with >1 napplet tab open the
controls (reload/back/pause/resume), navigation state, "allow always" notices,
NIP-07 traffic, and IME all routed to whichever tab was created last.
Collect all per-surface state into a NappletTab keyed by a client-stamped
session id (KEY_SESSION_ID on MSG_CREATE_SESSION and every control message):
- Controls/pause/resume resolve the target tab by id and act on its own WebView.
- Content server, shell handshake (declaredDomains), launch token, and page
state/notices are per tab; onShellMessage resolves the tab by its WebView.
- Each tab gets its OWN reply Messenger, so broker responses AND unsolicited
relay pushes come back tagged to the right tab — no id rewriting, per-tab
origin/fire-seq state.
- onSessionClosed drops the tab and destroys only its own WebView; the broker is
bound once for the whole service.
EmbeddedNappletController generates a unique id and stamps it on all messages.
Both embed hosts (browser + napplet) are now fully per-tab correct, including the
keyboard for multiple simultaneous tabs.

Extend the embedded keyboard to napplet/nsite surfaces. The shim's IME agent now
installs on any embedded surface (gated by __nappletImeProxy), reaching native
over whichever transport it has — the direct bridge for the browser, the trusted
shell relay for napplets — both through send().
- NappletContentServer gains an imeProxy flag that injects __nappletImeProxy
before the shim; NappletHostService sets it (embedded), the full-screen
NappletHostActivity leaves it off (native keyboard).
- NappletHostService relays ime.* between the applet (via the shell bridge) and
the client (MSG_IME_EVENT / MSG_IME_OP) — the shell already forwards all
message types, so no change to the trusted shell page.
- EmbeddedNappletController implements EmbeddedImeBridge, so EmbeddedTabLayer's
RemoteImeView drives it exactly like the browser.
Correct for a single nsite/napplet tab. Multiple simultaneous napplet tabs share
the host service's single client/bridge pointer (same limitation as reload/back/
NIP-07 there) — making that per-tab needs the session-scoping the browser host
already got; tracked as a follow-up.

Rework the host-side input proxy to mirror Flutter's TextInputPlugin /
InputConnectionAdaptor instead of forwarding individual IME ops:
- RemoteImeView ships the whole editing STATE (text + selection + composing
region) rather than per-op messages, coalesced across IME batch boundaries
(beginBatchEdit/endBatchEdit nesting, like Flutter's batchEditNestDepth). A
TextWatcher + onSelectionChanged flush captures every mutation, so the soft
keyboard, HARDWARE keyboards, autofill, paste, and context-menu edits are all
covered uniformly — they all mutate the same real Editable. Composing region is
read from the platform via BaseInputConnection.getComposingSpan*.
- The shim adopts that state and synthesizes the matching DOM input/composition
events (insertText / insertCompositionText / deleteContentBackward /
insertReplacementText, with compositionstart/update/end) so web frameworks
react as if typed natively — going beyond Flutter, whose consumer is a Dart
widget. A common prefix/suffix diff classifies each change.
- Beyond Flutter: backed by a REAL EditText, so the platform answers
getTextBeforeCursor/getExtractedText, suggestions, and spell-check for free
rather than hand-rolling a ListenableEditingState.
- showSoftInput is posted after focus settles (avoids the show no-op race).
This collapses the op vocabulary to ime.set (state) + ime.action and removes the
commit/compose/delete/key/setSelection messages.

The embedded browser renders cross-process through SurfaceControlViewHost, which
forwards touch but not the soft keyboard (the embedded window can't be an IME
target, and androidx.privacysandbox.ui never wires IME). So focusing a field in
an embedded page did nothing.
Bridge the keyboard instead: host it in the main app window and relay editing to
the page.
- Shim IME agent (embedded browser only, gated by __nappletImeProxy): tracks the
focused editable, reports focus/blur/external-change, and applies host ops
(commit / compose / delete / key / editor-action) with real input & composition
events. Scrolls the field into view on focus.
- NappletBrowserService relays ime.* envelopes between the page bridge and the
client (MSG_IME_EVENT / MSG_IME_OP), per tab.
- EmbeddedBrowserController implements EmbeddedImeBridge (parses events, sends ops).
- RemoteImeView: an invisible EditText in the main window that takes the keyboard
for the active tab. Keeps a real local Editable (so the platform handles
composing/suggestions/selection) while an InputConnection wrapper forwards every
op to the page. Maps web input types / enterKeyHint to inputType/IME action.
- EmbeddedTabLayer hosts the proxy bound to the active tab and shrinks the active
surface by the IME height so the page can scroll the field clear of the keyboard.
Covers <input>/<textarea> fully and contenteditable best-effort (plain text).
Napplet/nsite embeds still need their own wiring (the shell path); this is the
browser surface.

Warm every pinned bottom-bar favorite at app startup instead of lazily on first
visit, so a browser favorite (ditto, amy-lm, …) has already downloaded and is
local by the time the user taps it.
- EmbeddedTabFactory: the single place that builds a warm controller, shared by
the favorite screens and the new preloader so they produce the same session
keyed by the same id (whoever runs first wins; the other reuses it).
- EmbeddedTabPreloader (mounted next to EmbeddedTabLayer): sweeps the bottom-bar
favorites and acquires each. Retries for a bounded window so a napplet whose
event hasn't synced, or a Tor proxy still connecting, gets a chance to settle.
- Privacy gate: a Tor-routed site is never preloaded over clearnet while Tor is
merely still connecting — it waits for the proxy port. When Tor is off, or the
user opted the site out, clearnet is the real route, so it preloads at once.
- Seed an approximate viewport (EmbeddedTabHost.seedBoundsIfUnset) so preloaded
surfaces download as a full-size page rather than at the 1dp off-screen
fallback; the first real visit corrects the bounds.
Browser favorites fully preload+download. Napplet/nsite favorites get a warm
session but stay JS-paused until opened (the existing background-gating security
rule for "allow always" apps), so they don't run in the background.

- Each tab gets its OWN reply Messenger, so broker responses AND unsolicited
relay pushes come back already tagged to the right tab (the broker just echoes
replyTo) — no id rewriting, and per-tab originTokens/mint state.
- onSessionClosed drops the tab and destroys only its own WebView.
EmbeddedBrowserController generates a unique session id and stamps it on all
messages. Tor note: the WebView proxy override is process-global (Android has no
per-WebView proxy), so toggling Tor still affects every tab; only the toggled
tab is reloaded. The napplet host service has the analogous shared-instance
shape (black-out already fixed) but isn't session-scoped yet.

A single NappletBrowserService / NappletHostService instance is shared by every
embedded tab (they bind the same Intent), but each tab opens its own session
with its own WebView; the service's `webView` field is only a "latest" pointer.
The audit-batch "destroy stale WebView before rebuild" in createXWebView was
therefore destroying a *sibling* tab's live WebView whenever another browser/
napplet tab opened a session — exactly the repro: open A, switch to B (B's
create destroys A's WebView), back to A → black, B (created last) stays fine.
- Drop the destroy-on-create entirely; each session's WebView lives until that
session closes.
- onSessionClosed now destroys the closing session's OWN WebView (passed in)
and clears the shared pointer only if it still referenced it, so evicting one
tab can't tear down another either.

Two black-surface reports traced to the active-tab bookkeeping:
- Double-tapping a bottom-bar tab pops and re-adds the SAME route, so the
outgoing screen disposes AFTER the incoming one has already called
setActive(id). clearActiveIfMatches(id) then nulled the active id the new
instance just set (same id "matches"), leaving no active tab — every warm
surface gets shoved off-screen and the embed goes black. setActive now returns
a monotonic ownership token and the disposer clears only if it's still the
latest claim (clearActiveIfOwner), so a re-nav can't null the new owner.
clearActiveChrome got the same twin guard.
- Revert the reportBounds active-id guard added in the audit batch: it tied
contentBounds to the same fragile activeId, so a first-ever embed whose bounds
reported while the id was momentarily unset stayed at Rect.Zero (parked
off-screen → black). Bounds are reported unconditionally again; the two
screens cover the same content area, so there's nothing to clobber.

A vertical LinearLayout defaults its children to MATCH_PARENT width, so the
collapsed grabber chip's rounded background spanned the entire screen. Give the
grabber explicit WRAP_CONTENT layout params (centered) so only the chip shows.

Two regressions from this session's audit batch:
1. Bottom nav bar reset. Adding stable @SerialName discriminators to
BottomBarEntry changed the persisted polymorphic "type" value from the
fully-qualified class name to "builtIn"/"favorite", so configs written by an
earlier build no longer decoded — and the fallback returned an empty list,
blanking the bar. decodeBottomBarItems now migrates the old fully-qualified
discriminators to the short names (recovering the user's customized bar), and
any unrecognizable value falls back to the defaults instead of empty. Locked
with BottomBarEntrySerializationTest.
2. Pull-down sheet interfered with page taps. The expanded top sheet is a
full-width drawer with no way to dismiss except the grabber, so it sat over
the page. Hoist its expanded state into EmbeddedTabLayer (reset per tab) and
draw a full-area dismiss scrim behind the open sheet; collapsed, only the
small grabber is interactive and page taps pass through.

The full-screen browser/napplet-host activities still showed the old corner
pill/globe — which sits exactly where a site puts its own login avatar. Add a
native-View NappletControlSheet (the twin of the embedded tabs' Compose
TopControlSheet): a small grabber at the top edge that pulls down to the page's
controls, and wire both :napplet full-screen activities to it.
- NappletControlSheet: title row (shield/globe), optional Tor row, reload, and
optional "what it can access". Tor supports an inline toggle (browser) or a
tap-through to a confirm dialog (nSite host, where switching rebuilds the
session). Tap or vertical drag to expand/collapse.
- NappletBrowserActivity / NappletHostActivity: drop buildFloatingChip/chipGlyph
for buildControlSheet(); attach at Gravity.TOP, full width.
- Add short napplet_net_tor_label / napplet_net_open_label strings.

Durability & correctness:
- FavoriteAppsRegistry: tombstone removals made before async hydration so a
just-deleted favorite can't be resurrected by the disk merge.
- BottomBarEntry: stable @SerialName discriminators so persisted bottom-bar
configs survive class renames/moves.
- EmbeddedTabHost: guard reportBounds/setActiveChrome by active id so a
cross-fading outgoing screen can't clobber the incoming tab's bounds/chrome.
- EmbeddedNappletController: replay a parked-before-bound pause after session
create so a never-shown applet doesn't come up running.
- NappletBrowserService: bind the broker once (no leaked binding on re-create),
destroy a stale WebView before rebuilding, and reload only after the async
proxy override actually applies. NappletHostService: same WebView-reuse guard.
- NappletBrokerService: cap concurrent foreground leases so a misbehaving
sandbox can't pin Tor/relays with unbounded arbitrary keys.
Perf:
- Screens publish a remembered EmbeddedTabChrome; host short-circuits identical
publishes so the tab layer isn't recomposed every frame.
- AppBottomBar resolves favorites via an id-indexed map, not a per-entry scan.
- TopControlSheet keyed on the active tab so its expand state resets per tab.
Cleanup:
- Delete dead BrowserHostActivity + EmbeddedBrowserSurface + AppControlPuck and
their manifest entry; drop the unused `ready` surface state; null controller
refs on unbind; refresh stale z-order/host docs.

- Remove the shipped scroll/zoom diagnostics from NappletBrowserService (per-touch
MotionEvent log and per-page zoom log).
- NappletBrowserActivity now renews its foreground lease on a 30s heartbeat like
NappletHostActivity, so the broker's 90s watchdog can't reap it (tearing down
Tor/relays) while the browser is genuinely foreground.
- Persist the per-host Tor choice against the host actually displayed (webView.url),
not the start URL, so an in-page navigation doesn't save the choice to the wrong site.
