fix(media): six defects a code-review pass found in the og:media surface

Per CONTRIBUTING-WITH-AI.md, the branch got a review pass before the PR. All
six findings were real; none of them fire in the nostr.build case the feature
was built against, which is exactly why the tests missed them.

- Only a root-relative `og:audio`/`og:video` was resolved. A document-relative
  `media/x.mp3` -- and any value at all when the page URL fails to parse --
  reached the player verbatim as a relative string, which can only hang. Now
  every reference resolves against the page, and an unresolvable one is refused
  rather than passed on.

- Nothing checked the scheme. `og:audio = file:///...` with `audio/mpeg` passed
  the gate, letting a remote page aim the local player at a local URI. Playable
  media must now be http(s).

- The branch keyed on "is this playable", not "is this a player page", so an
  article that merely embeds a clip lost its entire card -- headline, summary,
  host, tap-through -- and got a bare player instead. `og:type` is now read and
  required to be `music.*` or `video.*`; an article, or a page that declares no
  type, keeps its card. The fixtures already carried the tag; nothing read it.

- Relaxing fetchComplete() broke the unstated "Loaded implies a non-empty
  image" invariant, so a cover-art-less track page painted a blank 180dp box in
  UrlPreviewCard (and through it UrlScreen and DisplayExternalId).
  WebBookmarksScreen guarded with `!= null` on a non-null String, which is
  vacuous. Both now test for blank.

- The new `audio/*` branch in UrlPreview produced Loaded states that the
  composer's two preview handlers did not cover, so a direct audio URL was
  handed to Coil to decode as an image and showed an empty square. Audio joins
  video there, as it already had in LoadUrlPreview.

- The video/audio branch never forwarded the fetched Content-Type to the
  player, contradicting its own new comment. An HLS playlist served as
  `audio/x-mpegurl` from an extension-less URL was then unrecognisable to
  MediaItemCache and played as progressive, i.e. not at all.

+
+### Amethyst's own icons are also a font
+
+The icons in `commons/.../commons/icons/*.kt` (Like, Reply, Reposted, Zap, …) are
+**also** compiled into a font, `composeResources/font/amethyst_icons.ttf`, and drawn
+as glyphs via `AmethystIconGlyph`. Drawing an `ImageVector` rasterises its paths into

+overrun P90 **-17.4%** on the feed scroll benchmark.
+
+**MANDATORY:** whenever you add or change an icon under `commons/.../commons/icons/`,

+```
+
+Both outputs must be committed together: codepoints are assigned in filename order,
+so adding an icon renumbers the ones after it, and a stale `AmethystIcons.kt` then
+points at the wrong glyph. Needs `fonttools` (`pip install fonttools`). The script
+prints any icon it could not convert — an icon that is skipped must keep using its
+`ImageVector`.
+ See `tools/material-symbols-subset/README.md` for details and
 prerequisites (`pip install fonttools brotli`).

A key missing in only some locales, inserted into all of them, duplicates in the ones that already had it. Drive each file's insertion off its own per-locale diff (see Step 6). In `commons`, a duplicate key is build-breaking: `convertXmlValueResourcesForCommonMain` fails with `Duplicated key '…'`. **Always run the post-insertion duplicate + XML-wellformedness gate in Step 6 before declaring done.** (Happened 2026-07-21 with `ps1_save_block` / `podcast_value_for_value` / `chats_history_relays`.)
 - **Declaring the pass done without running `:amethyst:lintPlayBenchmark`** — the duplicate-key + XML + `convertXmlValueResourcesForCommonMain` gate is necessary but nowhere near sufficient. `MissingQuantity` and `ImpliedQuantity` are errors, there is no lint baseline, and `abortOnError` is on, so a change that compiles and passes every check in Step 6's first half can still take CI red. Compiling is not evidence. (Happened 2026-08-13: 3 lint errors after a clean duplicate/XML gate and a green `compileFdroidDebugKotlin`.)
 - **Converting a `<string>` to `<plurals>` with `other` only** — "Crowdin fills the rest" is false; `MissingQuantity` errors immediately and CI fails before any sync. Supply every category the locale uses at conversion time, and re-check the declension rather than reusing the old text for `one`.
+- **Renaming or removing a key in `values/strings.xml` without deleting it from every locale in the same commit** — the surviving locale entries become orphans, and `ExtraTranslation` is an error. "Crowdin drops retired keys on its next sync" is the same false belief as the `other`-only shortcut above: lint runs on the tree you push. Worse, it's *partly* true — the sync cleans some locales and silently leaves others, so the files you happen to open look fine. Scan with the sub-second `.claude/hooks/orphan_strings_check.py` instead of the ~19-minute lint; see `amethyst/src/main/res/CLAUDE.md`, "Renaming or removing a string key". (Happened 2026-08-31: `route_video`/`new_short` left in 15 of 47 locales, 30 errors, red `main`.)
 - **Putting `tools:ignore` on a locale file** — Crowdin strips it on the next export. Suppressions belong on the source entry in `values/strings.xml`, which propagates. The `tools:ignore="Typos"` copies visible in cs/de/ar/eo/bn are the *result* of that propagation, not proof that locale-file attributes survive. (Happened 2026-08-13; it broke `main`.)
 - **Suppressing a lint rule on a key nothing references** — check `grep -rn "<key>" --include='*.kt'` first. `poll_results_voters` was a bare noun with no count, zero call sites, and an unlocalizable shape; deleting it retired the problem outright where a suppression would only have muted it.
 - **Comparing placeholders without a `(?<!\\)` guard** — `\%2$d` is an escaped literal to lint, but a naive `%\d+\$[sd]` regex matches the placeholder inside it and reports the string clean. A parity sweep missing this guard will certify a broken translation. Also treat a *repeated* index (`%1$s` twice where the base has it once) as legitimate — German does this where English says "They".

 # Find Non-Lambda Log Calls
 
 ## Overview
 
-Two related logging hygiene issues:
+Three related logging hygiene issues:
 
 1. **Lambda overload missing.** `Log.d/i/w/e` calls that use string interpolation without the lambda overload waste string allocation when the log level is filtered out in release builds.
 2. **Throwable dropped in catch blocks.** `Log.w/e` calls inside `catch (e: ...)` blocks that interpolate `${e.message}` but don't pass `e` lose the stack trace, and log nothing useful when `e.message` is null (NPE, IOException with no message, etc.).
+3. **Still on `android.util.Log`.** Files importing the platform logger bypass `Log.minLevel` and the `LogSink`, and have no lambda overload — so neither fix above can be applied to them. Step 0 finds these; the last section migrates them.
 
 ## When to Use

 **Important:** Tags can be string literals (`"Tag"`) or variables (`tag`, `LOG_TAG`). Run both patterns for each step.
 
+**The throwable-name alternation, used by Steps 2 and 3** — define it once and reuse it, rather than writing a shorter list in one step and a longer one in another:
+
+```bash
+THROWABLE='(e|t|it|ex|err|error|throwable|cause|tr)'
+```
+
+**Filter the noise before counting**, or the totals mislead: drop `/build/`, `/androidTest/` and `/src/test/` (release filtering doesn't apply to tests), and drop lines whose first non-space character is `//` or `*` — commented-out calls and KDoc examples both match these patterns. A `grep -vE ':[0-9]+: *(//|\*)'` handles the last one.
+
+### Step 0: Find files still on `android.util.Log` (run this first)
+
+**Two patterns — the fully-qualified one alone is a false negative.** Almost nobody writes `android.util.Log.w(...)` at the call site; they `import android.util.Log` and then write `Log.w(...)`, which is indistinguishable from the wrapper by call shape. The import is the reliable signal:
+
+```bash
+# the form that actually occurs
+grep -rln --include='*.kt' '^import android\.util\.Log$' . | grep -v '/build/' | grep -v PlatformLog
+
+# the rare fully-qualified call
+grep -rnE --include='*.kt' 'android\.util\.Log\.(d|i|w|e|v)\(' . | grep -v '/build/' | grep -v PlatformLog
+```
+
+On 2026-08-28 the fully-qualified pattern reported **0** while the import pattern found **16 production files** (9 in `nappletHost`, the rest in amethyst's `favorites/` and `napplet/`). Exclude `PlatformLog.android.kt`, which is the wrapper implementation and must call `android.util.Log`.
+
+These bypass the `Log.minLevel` filter and the `LogSink` indirection entirely, and — the practical consequence for this skill — **they have no lambda overload**, so Steps 1–3 cannot be applied to them until they are migrated. Subtract these files from the Step 1–3 candidate lists, or migrate them first (see the last section).
+
+### Step 0b: The patterns are line-anchored — sweep multi-line calls separately
+
+Every `pattern:` in Steps 1–3 matches a call written on one line. A call formatted as
+
+```kotlin
+Log.d(
+    TAG,
+    "WASTE ${url.url} dials=${r.tentatives.get()} " +
+        "fail=[${r.failures.entries.joinToString { … }}]",
+)
+```
+
+is **structurally invisible** to them. That biases the audit towards short calls and away from expensive ones — the multi-line form is what long, heavily interpolated messages look like, and those are exactly the ones worth deferring. A 2026-08-28 sweep converted three one-line banner calls in `BootRelayDiagnostics.kt` while walking past two `Log.d` calls in `forEach` loops immediately below them, running 25 and 20 iterations per census with nested `joinToString` in each — strictly the larger cost, three lines away.
+
+Catch them with the open-paren-at-EOL form, then read each hit:
+
+```bash
+grep -rnE --include='*.kt' 'Log\.[diwe]\($' . | grep -v '/build/'
+# or, to see the whole call:
+rg -U --multiline --type kotlin 'Log\.[diwe]\(\n[^)]*\$\{'
+```
+
+**Prioritise call sites inside loops over one-liners.** A `Log.d` in a 25-iteration `forEach` discards 25 built strings per pass; a one-line banner discards one.

 ## Do NOT Convert
 
 - **To lambda:** calls passing a `Throwable` parameter — the lambda overload `(tag) { message }` has no throwable parameter.
+- **To lambda: any call in a file that imports `android.util.Log`.** The platform `Log` has no lambda overload, so the conversion fails to compile with `None of the following candidates is applicable`. Either migrate the file first (below) or leave the call alone. (Hit on 2026-08-28: three edits in two files had to be reverted.)
 - Static string calls with no `$` interpolation — no allocation benefit.
 - Commented-out log calls.
 - Informational/intentional log of `e.message` *outside* a catch block (rare; usually means the exception was already handled and only the message is meaningful).
+
+## Migrating a file off `android.util.Log`
+
+This is what unlocks Steps 1–3 for the files Step 0 finds. It is a behaviour change, so check it rather than assuming — but in this repo the check has come out safe, and here is the reasoning to redo:
+
+1. **Which levels does the file use?** `grep -hoE 'Log\.[a-zA-Z]+' <files> | sort | uniq -c`. The wrapper has `d/i/w/e` only — **no `v`**, and no `getStackTraceString`. A `Log.v` call has no direct equivalent and needs a decision, not a rename.
+2. **Would the gate drop them?** `LogLevel { DEBUG, INFO, WARN, ERROR }`, the gate is `minLevel <= <level>`, and `Amethyst.DEFAULT_LOG_LEVEL` is INFO in debug, **WARN in release** (deliberately — so relay-protocol refusals stay visible in the field). The wrapper's own default is `DEBUG`. So `Log.w` and `Log.e` survive in every build type and in every process, including before `Amethyst.init` runs — which matters for `:napplet`. `Log.d`/`Log.i` **would** go silent in release; those need a conscious call.
+3. **Does the output move?** No. `PlatformLogSink` on Android delegates to `android.util.Log`, so lines land in logcat unchanged.
+4. **Can the module see quartz?** `nappletHost` already has `implementation(project(":quartz"))`. Check before assuming.
+
+Then: swap `import android.util.Log` → `import com.vitorpamplona.quartz.utils.Log`, run `./gradlew spotlessApply` (import order changes), and convert only the interpolated no-throwable calls to the lambda form. Calls that already pass a throwable keep the eager three-arg shape — the wrapper's `w(tag, msg, throwable)` matches exactly, so only the import moves.
+
+**Verify the throwables survived**, since a careless rewrite can drop the third argument silently:
+
+```bash
+grep -hoE 'Log\.[diwe]\([^)]*,\s*(e|it)\)' <files> | wc -l   # compare before/after
+```

+# Upstream issue draft — Compose `WindowInsets.ime` permanently wedges after a cancelled IME animation
+
+Target: Google IssueTracker → **component 612128 (Jetpack Compose)**.
+The library-specific component the docs link to (856989, from the "Create a new issue" button on
+the Compose Foundation release notes) does not grant public Create Issues permission, so this is
+filed one level up with a routing request at the top of the body.
+
+Status: **FILED as https://issuetracker.google.com/issues/552500419 (b/552500419)** on 2026-08-25,
+against component 612128 with a routing request. Remaining open item: the AOSP commit that introduced `runningAnimation`
+between 1.3.0 and 1.4.0-alpha01 has not been identified (android.googlesource.com returned 403
+to automated fetch). Adding the commit link before filing would help triage.
+
+---
+
+## Title
+
+`WindowInsets.ime` stops updating permanently when an IME animation is cancelled without `onEnd` (regression in 1.4.0, still present in 1.13.0-alpha01)
+
+## Routing
+
+Please reassign to the owner of **`androidx.compose.foundation` / `foundation-layout`**
+(WindowInsets). Filing here because component 856989 — the target of the "Create a new issue"
+button on the [Compose Foundation release notes](https://developer.android.com/jetpack/androidx/releases/compose-foundation)
+— does not grant Create Issues permission to external accounts. That documented path being
+unusable by the public is arguably a separate docs bug worth fixing.
+
+## Affected versions
+
+* **Broken:** `androidx.compose.foundation:foundation-layout` **1.4.0 → 1.12.0 (current stable) and 1.13.0-alpha01**
+* **Not broken:** 1.3.0 and earlier
+* Verified by inspecting published `-sources.jar` for 1.2.0, 1.3.0, 1.4.0-alpha01…rc01, 1.4.0,
+  1.5.0, 1.6.0, 1.7.0, 1.8.0, 1.9.0, 1.10.0, 1.11.0, 1.12.0, 1.13.0-alpha01.
+  `runningAnimation` and its guard are absent in 1.3.0 and present from 1.4.0-alpha01 onward,
+  textually unchanged since.
+* Reproduced on a Pixel 8, Android 17 (API 37). The API-30-only self-heal (below) means API 31+
+  has no recovery path at all.
+
+## Summary
+
+If a `WindowInsetsAnimation` is prepared and started but never ended — what a cancelled IME
+animation looks like — `InsetsListener.runningAnimation` stays `true` forever. From that point
+`onApplyWindowInsets` matches neither of its two branches, so `composeInsets.update()` is never
+called again and **`WindowInsets.ime` is frozen for the remaining life of the window**.
+
+Every `Modifier.imePadding()` in the app then holds a keyboard-height gap open with no keyboard
+on screen, permanently. `WindowInsets.imeAnimationTarget` keeps reporting correctly, because
+`updateImeAnimationTarget()` is called outside the guard — that asymmetry is the only reason a
+workaround is possible at all.
+
+## Reproduction
+
+Deterministic instrumented test, ~3s, no gestures and no timing dependence. It drives Compose's
+own listener through the cancelled-animation sequence using **public** interfaces
+(`WindowInsetsAnimationCompat.Callback`, `OnApplyWindowInsetsListener`); reflection is used only
+to obtain the listener instance for the view. Inside the androidx codebase `InsetsListener` is
+directly accessible, so `listenerFor()` can be deleted and the rest of the test used verbatim.
+
+```
+FAIL  aCancelledImeAnimationMustNotWedgeTheAnimatedInset
+      expected:<0> but was:<957>
+PASS  theAnimationTargetSurvivesTheWedge
+```
+
+The second test is expected to pass and is included on purpose: it pins the asymmetry between the
+two readings, and would catch a "fix" that broke `imeAnimationTarget` instead.
+
+The full test source is attached below.
+
+## Root cause
+
+`compose/foundation/foundation-layout/src/androidMain/kotlin/androidx/compose/foundation/layout/WindowInsets.android.kt`
+
+```kotlin
+override fun onPrepare(animation: WindowInsetsAnimationCompat) {
+    prepared = true
+    runningAnimation = true          // set here…
+}
+
+override fun onStart(animation, bounds): BoundsCompat {
+    prepared = false                 // …prepared cleared, runningAnimation left set
+    return super.onStart(animation, bounds)
+}
+
+override fun onEnd(animation: WindowInsetsAnimationCompat) {
+    prepared = false
+    runningAnimation = false         // …cleared ONLY here
+    …
+}
+
+override fun onApplyWindowInsets(view: View, insets: WindowInsetsCompat): WindowInsetsCompat {
+    savedInsets = insets
+    composeInsets.updateImeAnimationTarget(insets)   // unconditional — stays correct
+    if (prepared) {
+        if (Build.VERSION.SDK_INT == Build.VERSION_CODES.R) {
+            view.post(this)                          // self-heal, API 30 ONLY
+        }
+    } else if (!runningAnimation) {
+        composeInsets.updateImeAnimationSource(insets)
+        composeInsets.update(insets)                 // the animated inset — never reached when wedged
+    }
+    …
+}
+```
+
+After a cancelled animation: `prepared == false` (cleared by `onStart`) and
+`runningAnimation == true` (never cleared, because `onEnd` never came). Neither branch runs.
+`composeInsets.update()` is dead.
+
+### Why the existing self-heal does not help
+
+`run()` exists precisely to handle a cancelled animation, but:
+
+1. it is gated to `Build.VERSION.SDK_INT == Build.VERSION_CODES.R` (API 30 only), and
+2. it is posted only from the `if (prepared)` branch, and returns early unless `prepared` is still
+   `true` — which `onStart` has already cleared.
+
+So it covers "cancelled between `onPrepare` and `onStart`, on API 30". It does not cover
+"cancelled after `onStart`", on any API level.
+
+### Why applications cannot recover
+
+The only reset is `insetsListener.resetState()`, called from `WindowInsetsHolder.incrementAccessors()`
+when `accessCount` transitions `0 → 1`. `accessCount` is driven by `WindowInsetsHolder.current()`'s
+`DisposableEffect`, so it only reaches 0 when *every* insets consumer leaves composition
+simultaneously.
+
+In a single-Activity app whose shell (scaffold / bottom bar / drawer) always reads insets, that
+never happens — the holder is created once and lives for the whole process. There is no public API
+to force the reset. `WindowInsetsHolder` is `internal`.
+
+Multi-Activity apps mask this: a new Activity means a new `View`, a new holder, and fresh state, so
+the wedge dies with the Activity and reads as a transient glitch.
+
+### Regression point
+
+1.3.0's `onApplyWindowInsets` had no such gate and could not wedge:
+
+```kotlin
+override fun onApplyWindowInsets(view: View, insets: WindowInsetsCompat): WindowInsetsCompat {
+    if (prepared) {
+        savedInsets = insets
+        if (Build.VERSION.SDK_INT == Build.VERSION_CODES.R) view.post(this)
+        return insets
+    }
+    composeInsets.update(insets)      // unconditional once onStart cleared `prepared`
+    return …
+}
+```
+
+1.4.0 introduced `runningAnimation` and the `else if (!runningAnimation)` guard. Its own comment
+states the intent:
+
+> `// If an animation is running, rely on onProgress() to update the insets`
+> `// On APIs less than 30 where the IME animation is backported, this avoids reporting`
+> `// the final insets for a frame while the animation is running.`
+
+i.e. a **one-frame** cosmetic flash on **API < 30** was fixed by making the update path conditional
+on a flag that only `onEnd` clears — trading a single wrong frame on old devices for permanent
+state corruption on all of them. The compensating recovery was never widened past `SDK_INT == R`.
+
+## Real-world impact
+
+Observed in a production Compose app (Amethyst, a Nostr client; single-Activity, `NavHost`,
+77 `imePadding()` sites):
+
+* On a Pixel 8 / Android 17, after ordinary manual use, `WindowInsets.ime` pinned at 957px while
+  the window reported `ime frame=[0,0][0,0]` — keyboard gone — and stayed pinned for 85+ seconds
+  until the process was restarted. Nothing in the app cleared it.
+* Instrumented `WindowInsets.ime` vs `WindowInsets.imeAnimationTarget` across the failure:
+
+  ```
+  17:12:58.803  animated=882  target=957   ← healthy open, 13 intermediate frames
+  17:12:58.902  animated=957  target=957
+  17:13:00.584  animated=957  target=0     ← dismissed; animated frozen
+  17:13:02.430  animated=0    target=957   ← reopened; snaps, no intermediate frames
+  17:13:03.479  animated=957  target=0     ← dismissed; frozen permanently
+  ```
+
+  Note the loss of per-frame updates after the wedge: healthy transitions carry ~13 intermediate
+  values over ~264ms; post-wedge transitions carry none.
+* Because the app never navigates away from its single Activity and its shell always reads insets,
+  `accessCount` never returns to 0, so the wedge is permanent for the session. Sessions in this app
+  routinely run for days.
+
+The trigger for the underlying cancellation was not isolated — it is infrequent and required
+extended manual use to hit. The defect being reported is not the cancellation itself but that
+Compose enters a state it can never leave when one occurs. The attached test reproduces that state
+directly and deterministically.
+
+## Suggested fixes
+
+Roughly in order of how targeted they are:
+
+1. **Generalise the existing self-heal.** Post the `run()` reconciliation on all API levels, and
+   arm it after `onStart` as well as after `onPrepare`, so that an `onApplyWindowInsets` that
+   arrives with no intervening `onProgress` clears `runningAnimation` and applies `savedInsets`.
+   This preserves the API<30 one-frame behaviour the guard was added for, while bounding the
+   failure to a frame rather than forever.
+2. **Reconcile on dispatch.** In `onApplyWindowInsets`, if `runningAnimation` is set but no
+   `onProgress` has been received since `onStart`, treat the animation as finished and update.
+3. **Expose a reset.** A public way to reach `WindowInsetsHolder.resetState()` (or a documented
+   condition under which it runs) would at least let applications self-heal. Today they cannot,
+   short of reflection into an `internal` class — which R8 can rename or strip in exactly the
+   release builds where this occurs.
+
+(1) or (2) is preferable: (3) only makes the bug survivable rather than fixing it.
+
+## Environment
+
+* `androidx.compose.foundation:foundation-layout` 1.12.0 (Compose BOM 2026.08.00)
+* Pixel 8 (`shiba`), Android 17 / API 37, gesture navigation, Gboard, 120Hz
+* Also inspected: 1.13.0-alpha01 — identical listener code

+# Defaults stand in for the user's relay lists only while we have no event
+
+**Status:** proposal — not implemented
+**Goal:** first-login startup on a Tor-enabled install
+**Related:** `fix/tor-bootstrap-stall-and-ondemand`, `[[fresh-install-routes-everything-via-tor]]`
+
+## The rule
+
+Three states, currently collapsed into two:
+
+| we have | effective list | today |
+|---|---|---|
+| **no event** for the user | app defaults | defaults ✅ |
+| event, **empty** list | **empty** — the user chose nothing | defaults ❌ |
+| event with relays | those relays | those relays ✅ |
+
+Everything below follows from separating "we don't know" from "we know, and it's nothing".
+
+## Why the first login is slow
+
+On a fresh install **100% of relay traffic is Tor-routed by construction**.
+`TorRelayState.trustedRelays` is empty, so `TorRelayEvaluation.useTor()` falls through to
+`newRelaysViaTor` (**default true**) for every URL — and the kind-10002 that would populate it can
+only be fetched over Tor. Measured (SM-T220, same account, same ~app+8-10s login, fresh install
+each; the Tor-OFF arm sets the pref, force-stops, then starts the timed run so Arti never boots):
+
+| @20s census | Tor ON | Tor OFF |
+|---|---|---|
+| feed on screen | login+18s | **login+11s** |
+| relays opened | 18/40 | **32/41** |
+| relays serving events | 9 | **22** |
+| events ingested | 2,830 | **6,134 / 7,641** |
+
+≈7s of first paint and half the relay coverage.
+
+## Finding 1 — every `WithBackup` helper keys on emptiness, not absence
+
+This is a pre-existing bug against the rule above, and it must be fixed first because the whole
+feature depends on the distinction being real.
+
+```kotlin
+// AdvertisedRelayListEvent
+fun relays()         = tags.mapNotNull(AdvertisedRelayInfo::parse)                    // [] when none
+fun readRelaysNorm() = tags.mapNotNull(AdvertisedRelayInfo::parseReadNorm).ifEmpty { null }   // null!
+fun writeRelaysNorm()= tags.mapNotNull(AdvertisedRelayInfo::parseWriteNorm).ifEmpty { null }  // null!
+```
+
+| helper | fallback fires when | correct |
+|---|---|---|
+| `normalizeNIP65AllRelayListWithBackup` | event absent only | ✅ (by accident — `relays()` has no `ifEmpty`) |
+| `normalizeNIP65Read/WriteRelayListWithBackup` | event absent **or list empty** | ❌ |
+| `normalizeIndexerRelayListWithBackup` | `?.ifEmpty { null } ?: DefaultIndexerRelayList` | ❌ |
+| `normalizeSearchRelayListWithBackup` | `?.ifEmpty { null } ?: DefaultSearchRelayList` | ❌ |
+
+Consequence today: **a user who publishes a kind-10002 with only write relays gets
+`Constants.bootstrapInbox` silently substituted as their inbox list.** Same for a deliberately empty
+search or indexer list. The app overrides an explicit choice.
+
+The mirror problem sinks the obvious implementation: the `NoDefaults` variants return `emptySet()`
+for *both* "no event" and "empty event", so `trustedRelays.isEmpty()` cannot be used as the
+"do we have data yet" signal.
+
+**Fix:** make presence explicit, and never infer it from emptiness.
+
+```kotlin
+// absent -> defaults; present -> whatever it says, including nothing
+fun readRelayList(note: Note): Set<NormalizedRelayUrl> =
+    nip65Event(note)?.let { it.readRelaysNorm()?.toSet() ?: emptySet() } ?: Constants.bootstrapInbox
+```
+
+Same shape for write/all, and drop the `?.ifEmpty { null }` from the indexer and search helpers.
+Worth doing on its own merits even if the rest of this plan is dropped.
+
+**This removes the need for any window or timeout.** The fallback becomes a pure function of "do we
+have the event", so it ends the instant one arrives — even an empty one. No per-account bookkeeping,
+no 30s backstop, no race to close.
+
+## Finding 2 — do NOT put defaults into `TrustedRelayListsState`
+
+Tempting (it already merges all nine lists) but wrong: `account.trustedRelays.flow` feeds
+`Account.kt:454`
+
+```kotlin
+isInMyRelayList = { relayUrl -> ... it in trustedRelays.flow.value }
+```
+
+which feeds `RelayAuthPermissionLedger` -> `RelayAuthResolver` -> **the NIP-42 AUTH decision**.
+Adding defaults there would make the app **auto-AUTH to the six hardcoded bootstrap relays as if
+they were the user's own** — signing a challenge with the user's key and revealing the pubkey — at
+exactly the moment we are also going clearnet. That converts a modest timing leak into a signed
+identity assertion. See `[[relay-auth-always-was-gated]]` and `[[inbox-wine-notify-auth-billing]]`
+for why AUTH is the sensitive edge.
+
+(The `saveTrustedRelayList(trustedRelays + relay)` write path in `RelayGroupChannelListScreen:449`
+is **not** a hazard — it reads `account.trustedRelayList` (the NIP-51 list), not the merged
+`trustedRelays`. Checked.)
+
+**Instead:** add a separate, purpose-named flow consumed only by Tor evaluation, e.g.
+`Account.relaysAssumedWhileUnknown` — the union of the with-defaults views, non-empty only while the
+corresponding events are absent. `AccountsTorStateConnector` feeds it into a new
+`TorRelayState.assumedRelays`. Nothing else reads it.
+
+## Where the check goes in `useTor()`
+
+```
+torType == OFF        -> false
+isLocalHost           -> false
+isOverlayNetwork      -> false
+isOnion               -> onionRelaysViaTor
+in moneyOpRelayList   -> moneyOperationsViaTor
+in dmRelayList        -> dmRelaysViaTor
+in trustedRelayList   -> trustedRelaysViaTor
+in assumedRelayList   -> trustedRelaysViaTor      <-- new, immediately above the fallback
+else                  -> newRelaysViaTor
+```
+
+Landing immediately above the fallback means **.onion, money-operation and DM relays keep their own
+policy for free** — the change can only ever affect URLs that would have been treated as "new".
+
+Resolve to `trustedRelaysViaTor`, **not** a hardcoded `false`:
+
+- default user (`false`) -> clearnet -> fast start;
+- hardened user (`true`) -> stays on Tor, automatically, with no new setting to discover.
+
+That is the difference between "the app overrides you" and "the app treats its stand-in list the way
+you asked your own list to be treated".
+
+## Privacy, for the PR body
+
+The window correlates the user's **IP with their pubkey** at ~6 hardcoded relays, because the REQ
+asks those relays for that pubkey's events. A first login is the most sensitive moment there is.
+
+What makes it defensible: **`trustedRelaysViaTor` already defaults to false**, so the moment
+kind-10002 lands the user's own relays are dialled over clearnet anyway. This moves an existing
+disclosure slightly earlier, to a different well-known set. It is not a new class of exposure for
+the default configuration — and it is *not* an AUTH disclosure, provided Finding 2 is respected.
+
+If `trustedRelaysViaTor` ever becomes default-true, **this feature must be revisited in the same
+commit** — its justification disappears. Leave a comment at the default linking the two.
+
+Residual, worth verifying rather than assuming: `useTor()` is keyed by relay **URL**, and the pool
+multiplexes every subscription for a URL over one socket. During the window, anything addressed to a
+default relay rides that clearnet socket — including a kind-1059 giftwrap subscription, since the DM
+list is also absent. Measure it (below) before deciding it is acceptable.
+
+## Testing
+
+Unit — the rule itself, per list type: absent event -> defaults; present-but-empty -> **empty**;
+present-with-values -> values. The middle case is the regression guard and the one that fails today.
+
+Unit (`TorRelayEvaluationTest`): an assumed relay resolves to `trustedRelaysViaTor` (both values);
+.onion / money-op / DM keep their own policy while also listed as assumed; a non-assumed "new" relay
+still resolves to `newRelaysViaTor`; an empty assumed set is byte-for-byte today's behaviour.
+
+Unit: `isInMyRelayList` does **not** see assumed relays (guards Finding 2 permanently).
+
+Device — the number that justifies the change. `relaytiming.sh` + `BootRelayDiag` census,
+`VERBOSE_LOGS=true` benchmark build, fresh install each, counterbalanced, n>=3:
+- primary: login -> first note; login -> own profile + follow list;
+- secondary: relays opened / serving / events at the 20s census;
+- guard: grep the verbose log for any request to a default relay during the window that is not for
+  the account's own pubkey, and for any AUTH sent to one.
+
+Harness traps (all in `[[fresh-install-routes-everything-via-tor]]`): the tablet raises its lock
+screen during long waits (`wm dismiss-keyguard`, not just `KEYCODE_WAKEUP`); the login layout shifts
+when the IME opens, so dismiss it before tapping fixed coordinates; `BACK` on the home screen exits
+the app; always assert the run left the login screen before trusting its timing.
+
+## Expected outcome
+
+Approach the Tor-OFF column: ≈**-7s to first paint, ~2x relay coverage** in the first 20s, with
+everything after the first event behaving exactly as today.
+
+If the gain is materially smaller, the likely cause is that the feed is gated on outbox-discovered
+relays (which stay "new", hence Tor) rather than the user's own list — in which case the win is
+limited to profile and follows, and may not be worth the privacy cost. Decide on the numbers.
+
+## Order of work
+
+1. Fix the absent-vs-empty bug in the four helpers + tests. Independently correct; ship separately.
+2. Add `relaysAssumedWhileUnknown` + `TorRelayState.assumedRelays` + the `useTor()` branch.
+3. Device A/B. Keep only if it earns its keep.

+# NIP-A3 Payment Targets in the zap picker — v1
+
+**Status:** proposal
+**Modules:** `quartz`, `commons`, `amethyst`
+**Scope:** when a note's author publishes a NIP-A3 payment target, **an
+installed app can handle it**, and the note carries no NIP-57 zap split — show
+one amount-less chip per such target that hands off to that app.
+
+> **Revised after the first implementation.** This document originally gated the
+> chip on *symmetry* — both parties publishing the same protocol — and capped the
+> row at two chips. Both are gone: the gate is capability alone (can anything on
+> this phone open the URI), there is no cap, and the setting now defaults **on**.
+> Sections below that argue for symmetry are kept for the reasoning, but §5 is
+> the current rule.
+
+Deliberately excluded from v1: amounts, in-app payment, receipts, fiat
+conversion, desktop.
+
+---
+
+## 1. Why v1 has no amounts
+
+Zap presets are **sats**. A `venmo` / `iban` / `upi` chip cannot send 1000
+sats, and there is **no FX or bitcoin-price service anywhere in this repo**
+(grepped `quartz`, `commons`, `amethyst`). So v1 does not pretend: the chip
+carries no number, emits no RFC-8905 `amount=`, and the amount is named in the
+external app. The UI has to *say* that rather than leave a suspicious blank —
+see §4.
+
+Corollary: **the note's zap counter will not move.** No kind:9735, nothing to
+count. In code it is a rail; to the user it must read as *pay*, not *zap*.
+
+---
+
+## 2. The layout decision — and the refactor it deletes
+
+> This is the one place v1 diverges from the sketch, and the reason is that it
+> makes the change roughly half the size.
+
+The sketch was "add the icons to the toggle." The toggle is the segmented
+control **inside each amount pill** (`UnifiedZapAmountChip`,
+`ReactionsRow.kt:2362`). Putting an amount-less rail there has two costs:
+
+1. **It repeats.** With presets of 1000/5000/10000, the identical amount-less
+   Venmo segment renders three times and means the same thing each time.
+2. **It forces `ZapRail` to become a sealed interface.** The enum
+   (`ReactionsRow.kt:2481`) is payload-free, so a segment can't know *which*
+   target it opens. Making it data-carrying drags in `present`, `preferred`,
+   `selectedRail`, `ZapRailIcon`, `previewPreferredRail`, `previewRailsFor`
+   and the settings preview row — and, because `PaymentTarget` has no
+   `equals`, breaks the `remember(preferred, present)` key so the user's
+   selection resets on recompose.
+
+**Instead: render the chip as a sibling of the amount pills**, appended to the
+existing `FlowRow` in `ZapAmountChoiceGrid` (`ReactionsRow.kt:2297`), next to
+the `Tune` preset-editor button. It wraps for free, it renders **once**, and
+`ZapRail`, `UnifiedZapAmountChip` and every preview stay **completely
+untouched**. Same popup, same place the user is already looking.
+
+If an FX service ever lands and the amount becomes expressible, the chip moves
+into the toggle then — that is the natural migration, not a reason to pay for
+it now.
+
+---
+
+## 3. Intent discovery — the constraint that decides it
+
+`targetSdk = 37`. Under Android 11+ package visibility,
+`queryIntentActivities` returns **empty** for any intent not covered by a
+`<queries>` declaration — so *without a manifest change this feature silently
+shows nothing on every modern device*. The existing `<queries>` block
+(`AndroidManifest.xml:4`) covers only `nostrsigner`, TTS, Health Connect and
+Tor.
+
+### 3.1 Manifest
+
+Add one `<intent>` per scheme we probe. The important economy: an arbitrary
+user-typed type (`iban`, `upi`, `pix`, …) always falls back to
+`payto://<type>/<authority>`, so **one `payto` entry covers every generic
+type**. Only the ~12 special-cased crypto schemes in `paymentTargetStyleFor`
+(`DisplayPaymentTargets.kt:190`) need their own entries.
+
+```xml
+<intent>
+    <action android:name="android.intent.action.VIEW" />
+    <data android:scheme="payto" />
+</intent>
+<!-- + one each: bitcoin, lightning, liquidnetwork, ethereum, monero, dash,
+     zcash, bitcoincash, litecoin, dogecoin, solana, tron -->
+```
+
+Use **`<queries>`, never `QUERY_ALL_PACKAGES`** — the latter is a
+policy-restricted permission on Play and would need a declaration; specific
+`<intent>` filters need nothing. On minSdk 26–29 `<queries>` is ignored and
+everything resolves, which is a strict superset of the gated behaviour.
+
+### 3.2 https targets are exempt
+
+`cashapp` / `venmo` / `paypal` map to `https://…`, which a browser always
+resolves — discovery would be a tautology. **Skip discovery for https
+targets and always show them**: opening `venmo.com/<handle>` in a browser is a
+legitimate way to pay, so nothing is broken. For these three types the chip is
+therefore gated only on the author having published one.
+
+**But §4.2 still needs the control probe here.** To tell a real app handler
+from a browser, resolve a control `https://<nonexistent-host>/` and treat the
+target as app-backed only if its resolver set contains a package outside that
+control set. It never gates the chip — it decides whether the chip wears the
+app's icon or the brand-colour glyph, and a Chrome icon on a Venmo chip is
+worse than no icon at all.
+
+### 3.3 The cache — keyed by scheme+host, warmed from the open picker
+
+The naive cache is per-post and lazy. With symmetry gone the probe set is the
+author's target list, so:
+
+> **Probe the targets of the one author whose picker is open** — typically 1–5
+> entries — and **merge** the answers into the cache. Merging matters: replacing
+> would evict what was learned about every other author the moment a second
+> picker opened. Feed rendering still never triggers a probe.
+
+- **Key:** `"<scheme>://<host>"`, e.g. `payto://iban`, `bitcoin://`. Scheme
+  alone is too coarse — an app may declare `android:scheme="payto"
+  android:host="iban"`, so a scheme-only hit would wrongly claim `payto://upi`
+  is handled.
+- **Warm:** a `LaunchedEffect` keyed on the author's observed kind:10133 probes
+  that handful of keys off the main thread when the picker opens.
+- **Read:** synchronous map lookup — required, because
+  `RailCapabilityResolver.peek` is called from inside `remember {}`.
+- **Recomposition:** the map must be a `MutableStateFlow<Map<String, Boolean>>`,
+  not a bare `ConcurrentHashMap`. A plain map write is invisible to Compose and
+  the chip would not appear until something else recomposed.
+- **Invalidation:** clear on app foreground (`ProcessLifecycleOwner`
+  `ON_START`) and re-warm — this is exactly the "user left, installed Venmo,
+  came back" flow. A `PACKAGE_ADDED`/`REMOVED` receiver is more precise but is
+  more moving parts than v1 needs.
+
+Home: `amethyst/…/service/payments/PayToAppAvailability.kt` (Android-only;
+`PackageManager` has no KMP equivalent). The scheme mapping it needs moves out
+of the UI file into `commons` (§6.0).
+
+---
+
+## 4. The chip's face
+
+### 4.1 Saying "the app decides the amount"
+
+An amount-less chip beside pills that all show numbers reads as a bug unless
+it is visibly a *different kind of thing*. Three cues, no extra layout:
+
+1. **No number.** Icon + protocol label only (`VENMO`).
+2. **A different terminal glyph.** `MaterialSymbols.OpenInNew` instead of the
+   `ArrowForward` every amount segment uses — "this leaves the app."
+3. **A string that says it outright**, e.g. *"Amount set in %1$s"*, shown as
+   the chip's `contentDescription` and as a toast on long-press.
+
+**Both glyphs are already in `MaterialSymbols.kt`** (`OpenInNew:280`,
+`AccountBalanceWallet:27`) — **no `tools/material-symbols-subset/subset.sh`
+run is needed**, and §4.2 adds no new glyphs either.
+
+Long-press must **not** inherit `onChangeAmount` (the sat-preset editor is
+meaningless here); it copies the authority, matching `PaymentTargetChip`'s
+long-press on the profile.
+
+### 4.2 Which icon it wears — the installed app's, not a bundled logo
+
+**This already works in this codebase.** `ExternalSignerButton.kt:118` renders
+installed NIP-55 signers with `it.loadLabel(pm)` / `it.loadIcon(pm)` →
+`toBitmap()` → Coil's `rememberAsyncImagePainter`, off the back of
+`getExternalSignersInstalled` (`quartz/…/IsExternalSignerInstalled.kt`), which
+is `queryIntentActivities(ACTION_VIEW, "nostrsigner:")` — **the same call
+§3 already makes for discovery.** The `ResolveInfo` we keep to answer "can
+anything open this?" also carries the icon and the app's own name. The icon is
+therefore very close to free; what it costs is care.
+
+**Do not bundle brand logos.** Three reasons, in order of weight:
+
+1. **Trademark, not licence.** `CLAUDE.md`'s dependency gate covers *code*
+   licences; a Venmo or PayPal mark shipped inside an MIT APK is a separate
+   trademark question. Referential use is usually permitted, redistribution of
+   the mark often is not. That is a maintainer's call, not a silent one.
+2. **The type space is unbounded.** `PaymentTargetsViewModel.addTarget` accepts
+   any `type.trim().lowercase()`, so a bundled set can never be complete —
+   `pix`, `upi`, `swish`, `interac` and the next one all miss.
+3. **The codebase already decided this.** `paymentTargetStyleFor` pairs brand
+   *colours* (`VENMO_BLUE #008CFF`, `PAYPAL_DEEP_BLUE #003087`,
+   `CASHAPP_LIME #00E64D`) with the generic `AccountBalanceWallet` glyph.
+   Brand colour + generic glyph is the established pattern; keep it as the
+   fallback. Brand marks are also absent from Material Symbols, so each would
+   be a hand-authored `ImageVector` like `CustomHashTagIcons.Cashu`.
+
+So: **the installed app's icon *is* the brand icon**, sourced from the device
+instead of shipped. It is self-limiting in the right direction — the "popular
+options" are exactly the ones with an app installed.
+
+**Four things the precedent gets away with and we would not:**
+
+- **Load once, in the warm step.** `ExternalSignerButton` calls `loadIcon()` +
+  `toBitmap()` inside a `LazyColumn` item, so it re-runs on recomposition —
+  tolerable in a one-shot dialog, not in the zap popup. `loadIcon` reads the
+  target APK's resources, so it is I/O: do it in §3.3's off-main warm and
+  cache the **`ImageBitmap`**, never the `Drawable`.
+- **Size and mask it.** minSdk is 26, so any icon may be an
+  `AdaptiveIconDrawable`: a 108×108 canvas whose outer margin the launcher
+  masks away. A bare `toBitmap()` drawn at 18dp shows a small logo floating in
+  padding. Use `toBitmap(px, px)` at the target size plus
+  `Modifier.clip(CircleShape)` — what a launcher does. The precedent renders
+  at 48dp and gets away with it.
+- **Pick one app, or none.** `payto://` can resolve to several. Ask
+  `resolveActivity(intent, MATCH_DEFAULT_ONLY)` for the user's default; when
+  Android hands back its `ResolverActivity` (no default set) there is no app
+  to name — fall back to the glyph rather than showing the chooser's icon.
+- **Accept that it cannot be tinted.** Every other rail is a monochrome glyph
+  tinted `BitcoinOrange` / `onSurface`. A full-colour raster can't join that
+  scheme — which is arguably the point: it is the visual signal that this
+  segment leaves the app. It needs the circular clip and a slightly smaller
+  optical size to sit beside 18dp glyphs.
+
+**This promotes the https control-probe from a nicety to v1 work.** §3.2 exempts
+`venmo` / `paypal` / `cashapp` from discovery because a browser always resolves
+`https://`. That is fine for *gating*, but not for *icons*: with only a browser
+installed, `resolveActivity` returns **Chrome**, and a Chrome icon on a Venmo
+chip is worse than no icon. So an https target needs the control probe
+(resolve `https://<nonexistent-host>/`, treat the target as app-backed only if
+its resolver set contains a package outside that control set) to decide
+**icon vs brand-colour glyph**, even though it never gates the chip.
+
+---
+
+## 5. Gates (all must hold)
+
+1. Setting `showPayToZapChip` — **default on**. The chip only ever shows a
+   target its author chose to publish, to a device that can already open it,
+   so the discovery gate is doing the real narrowing (`UiSettings.kt:67` →
+   `UiSettingsFlow.kt:59` → `UISharedPreferences.kt:192`).
+2. Note has **no** zap split: `zapSplitSetup().isNullOrEmpty()`. payto can't
+   fan out and returns no receipt. `RailCapabilityResolver.peek` **already
+   computes `splits`** — one-line reuse.
+3. Recipient (note author) publishes ≥1 handoff-class target.
+4. §3 says an app can handle it (or it's https). **This is the substantive
+   gate**; everything else is a precondition.
+
+No cap: every openable target is offered. Discovery is what bounds the row —
+a target with nothing to open it never reaches the picker.
+
+**Handoff-class** excludes the wallet-covered types — `lightning`/`ln`/`lnurl`
+and `bitcoin`/`btc`/`onchain` *are* the existing LIGHTNING and ONCHAIN rails.
+Without this exclusion the picker grows a second Bolt icon beside the first.
+
+---
+
+## 6. Implementation
+
+### 6.0 Prep — no behaviour change
+- `quartz`: `PaymentTarget` → `data class` (it has no `equals` today; needed
+  for list keys and dedupe, and it fixes the hand-rolled field-by-field
+  compare in `PaymentTargetsViewModel.addTarget`).
+- `commons/…/model/payments/PaymentTargetTypes.kt` (package exists, holds
+  `PaymentSourceResolver`): `canonical(raw)`, `isWalletCovered(canonical)`,
+  `schemeFor(canonical)`. Move `LIGHTNING_TARGET_TYPES` /
+  `BITCOIN_TARGET_TYPES` (`DisplayPaymentTargets.kt:67,70`) and the scheme half
+  of `paymentTargetStyleFor` here — today they are duplicated twice inside one
+  Android UI file, and discovery needs them too.
+- `commons/…/model/User.kt`: `paymentTargetsNote` + `paymentTargets()`,
+  mirroring `nutzapInfoNote` (`User.kt:79`).
+
+**No new relay subscription:** kind 10133 already rides in
+`UserMetadataForKeyKinds` beside kind:0 and kind:10019
+(`FilterUserMetadataForKey.kt:50`), so the recipient's targets are in cache by
+the time the note renders — same as the nutzap rail.
+
+### 6.1 Matcher — pure, headless
+`commons/…/model/payments/PayToRailMatcher.kt`: canonicalize both sides, drop
+wallet-covered types, intersect on type, dedupe by type. No Android, no
+Compose.
+
+### 6.2 Discovery
+`amethyst/…/service/payments/PayToAppAvailability.kt` per §3.3 + the manifest
+`<queries>` entries per §3.1. Each cache entry holds what §4.2 needs as well as
+the yes/no: `{ resolves: Boolean, label: String?, icon: ImageBitmap? }` —
+decoded once in the warm step at the 18dp target size, never per composition.
+Icon and label are null for the no-default (`ResolverActivity`) and
+browser-only cases, and the chip falls back to the brand-colour glyph.
+
+### 6.3 Capability
+- `RailCapability` += `payToTargets: List<PaymentTarget> = emptyList()` —
+  defaulted, so `RailCapabilityCashuStatusTest` and every existing call site
+  compile untouched.
+- `peek(..., senderTargets = emptyList(), payToEnabled = false, available = emptyMap())`
+  — **defaulted, because `zapClick` also calls `peek`**
+  (`ReactionsRow.kt:1464`) for the one-tap fast path, which must stay
+  Lightning-only. Returns empty when splits exist.
+- `observeZapRailCapability` (`ReactionsRow.kt:2098`) adds four inputs, each
+  both a subscription trigger and a `remember` key — the contract spelled out
+  in the "do NOT delete these as unused" comment at `ReactionsRow.kt:2105`:
+  `paymentTargetsState.flow`, the author's `paymentTargetsNote`,
+  `uiSettingsFlow.showPayToZapRail`, and the availability `StateFlow`.
+
+### 6.4 UI
+One new `PayToHandoffChip` composable appended to `ZapAmountChoiceGrid`'s
+`FlowRow`. Action: `uriHandler.openUri(...)`; keep the existing try/catch →
+`no_payment_app_found_for_type` toast (string exists) as a belt-and-braces
+fallback for the race where the app is uninstalled between warm and tap. It
+must not touch `zappingProgress`, `zapStartingTime` or `accountViewModel.zap`.
+
+### 6.5 Settings + strings
+`showPayToZapRail` through the `showOnchainWallet` chain + `SettingsCatalogBuilder`;
+new strings; changelog.
+

+
+---
+
+## 8. Open decisions
+
+1. **Chip placement** — sibling vs inside the toggle (§2). Recommend sibling:
+   renders once and deletes the whole `ZapRail` refactor. Flagged because it
+   diverges from the original sketch.
+2. **Default for `showPayToZapRail`** — recommend **off**, matching how
+   `ReactionRowAction.Pay` already ships disabled.
+3. **Private rumors** — on-chain is suppressed there (it would e-tag the
+   rumor). A payto handoff publishes nothing, so it is arguably safe.
+   Recommend **allow**, noting the divergence from the on-chain precedent.
+4. **`ReactionRowAction.Pay` overlap** — recommend keeping both, `Pay`
+   disabled by default: `Pay` browses *all* of a recipient's targets, this
+   chip is the *matched, installed, splitless* shortcut.
+5. **Colour icon beside monochrome glyphs** (§4.2). The app icon can't be
+   tinted, so the chip will be the one full-colour thing in the popup.
+   Recommend **accepting** it as the "this leaves the app" signal — but it is a
+   visible break from the rail iconography and worth an explicit yes.
+6. ~~**Symmetry heuristic**~~ — *removed; see the note at the top.* It was
+   right for closed loops (Venmo, Cash App, UPI),
+   arguably too strict for open ones (Monero: a sender needs a wallet, not a
+   published address). Ship strict; relaxing later is additive. Note that
+   intent discovery already covers much of what symmetry was proxying for, so
+   dropping symmetry for scheme-based types is a live option.

+# Entity Ratings (kind 34259) — parse, ingest, render, feed
+
+**Status:** implemented — see §11 for what shipped and where this document was wrong
+**Modules:** `quartz`, `commons`, `amethyst`
+**Scope:** parse kind-34259 entity ratings, ingest them into `LocalCache`, render
+them as a star + review card, and make them appear in the Home feed behind a
+Settings › Home toggle.
+
+Deliberately excluded from v1: composing/publishing a rating from Amethyst,
+aggregate ("3.8★ from 12 raters") rollups on the rated object, and the kind-30040
+publication *reader*. §8 says why and what each would take.
+
+---
+
+## 1. What we are implementing
+
+Kind 34259 is **not a merged NIP**. The upstream spec is
+[`XYZ.md` in `abh3po/nostr-polls`](https://github.com/abh3po/nostr-polls/blob/main/XYZ.md)
+(Pollerama) — a deliberately generic "rate anything" addressable kind. It defines
+exactly three tags:
+
+| tag | spec meaning |
+| --- | --- |
+| `d` | id of the rated entity; prefixed with the `m` value when the bare id isn't unique (`hashtag:books`) |
+| `m` | mark — entity type: `event`, `profile`, `relay`, `hashtag`, `books`, `movies`…; empty ⇒ a nostr event |
+| `rating` | "Number less than 1 and greater than 0" |
+
+Everything else in the wild sample below is an **extension by
+`silberengel/jumble`** (the web client that signs `client: imwald`), built in
+`src/lib/draft-event.ts:1626` for rating a kind-30040 NKBIP-01 publication:
+
+```json
+{ "kind": 34259,
+  "tags": [
+    ["d", "books:30040:5736…edc:wuthering-heights"],
+    ["m", "books"],
+    ["rating", "1.000"],
+    ["s", "5"],
+    ["a", "30040:5736…edc:wuthering-heights"],
+    ["A", "30040:5736…edc:wuthering-heights"],
+    ["e", "aff2…287", "", "5736…edc"],
+    ["k", "30040"],
+    ["p", "5736…edc"],
+    ["c", "true"]
+  ],
+  "content": "This is my very favorite book. …" }
+```
+
+`s` = raw 1–5 stars, `a`/`A` = the rated coordinate, `e` = the index event id,
+`k` = rated kind, `p` = rated author, `c` = "has a written comment".
+
+**Design consequence:** we implement the *generic* kind with typed accessors, and
+treat `m` as the dispatch key for presentation. We do not hardcode books into the
+event class. Books is simply the first mark we render richly.
+
+---
+
+## 2. The two parsing traps
+
+These are the whole reason this needs a plan rather than a 40-line event class.
+
+### 2.1 `rating` is ambiguous at exactly 1
+
+The spec says 0 < rating < 1. jumble publishes `"1.000"` for five stars —
+outside the spec's own stated range. Other clients publish a plain `1`–`5`.
+So the string `"1"` means **either** 1.0 (⇒ 5 stars) **or** 1 raw star, and the
+`rating` tag alone cannot tell you which.
+
+jumble resolves it one way (`event-metadata.ts:1364`: `raw <= 1` ⇒ fraction ⇒
+×5), which silently turns a genuine 1-star review from a raw-scale client into a
+5-star one. We should not copy that blindly.
+
+**Rule for our parser** (`EntityRatingEvent.stars()`):
+
+1. If an `s` tag is present and parses to 1..5 → that is the star count. Authoritative.
+2. Else if `rating` parses to a value in `0.0..1.0` **inclusive** → `rating × 5`.
+3. Else if `rating` parses to `1.0 < x <= 5.0` → raw stars.
+4. Else → `null` (render the comment, no stars) — never 0, never a guess.
+
+Step 1 is what makes `1` unambiguous for every event jumble emits, and step 2
+accepts the boundary value the spec's prose excludes. Pin all four branches with
+tests, including the `"1"`-without-`s` ambiguity resolving to 5 (documented as
+the interop choice, with the reasoning in a comment).
+
+### 2.2 `d` carries the mark prefix
+
+`d` is `books:30040:<pubkey>:<identifier>` — the coordinate with an `m:` prefix.
+The parser must strip a leading `<mark>:` before treating the remainder as an
+`Address`. And because only Pollerama-derived clients apply the prefix, any REQ
+by `#d` must ask for **both** the prefixed and bare forms
+(jumble's `publicationRatingDTagsForQuery` does exactly this).
+
+---
+
+## 3. Quartz — `experimental/ratings/`
+
+Not a merged NIP ⇒ `experimental/`, alongside `agora`, `birdstar`, `nipsOnNostr`.
+
+```
+quartz/src/commonMain/kotlin/com/vitorpamplona/quartz/experimental/ratings/
+├── EntityRatingEvent.kt      # kind 34259, AddressableEvent
+├── RatingMark.kt             # the `m` vocabulary + prefix strip/apply
+├── TagArrayBuilderExt.kt     # builder DSL (rating/mark/target/stars)
+└── tags/
+    ├── RatingTag.kt          # ["rating", "0.000".."1.000"]
+    ├── StarsTag.kt           # ["s", "1".."5"]  (jumble ext)
+    └── HasCommentTag.kt      # ["c", "true"]    (jumble ext)
+```
+
+`EntityRatingEvent` surface:
+
+```kotlin
+class EntityRatingEvent(...) : Event(...), AddressableEvent {
+    fun mark(): String?                 // `m`, null ⇒ "event" per spec
+    fun ratingFraction(): Double?       // `rating` clamped to 0.0..1.0, null if unparseable
+    fun stars(): Double?                // §2.1 resolution ladder
+    fun targetAddress(): Address?       // `a`/`A` first, then the de-prefixed `d`
+    fun targetEventId(): HexKey?        // `e`
+    fun targetKind(): Int?              // `k`
+    fun targetAuthor(): HexKey?         // `p`
+    fun hasComment(): Boolean           // `c` == "true", OR content.isNotBlank()
+    companion object { const val KIND = 34259 }
+}
+```
+
+`targetAddress()` prefers `a`/`A` because they are unambiguous; the de-prefixed
+`d` is the fallback for clients that only publish `d` (which the spec permits —
+`a` is not in the spec at all).
+
+Also implement `SearchableEvent.indexableContent()` returning `content` — a
+review is prose and belongs in NIP-50 search. Cheap, and the `searchable-events`
+skill documents the diff surface external engines mirror, so note it there.
+
+**Registration checklist** (each is a real edit, all found by grep):
+
+| File | Edit |
+| --- | --- |
+| `quartz/…/utils/EventFactory.kt` | branch in the `when` (before the `else` at :845) |
+| `quartz/…/kinds/KindNames.kt` | English name "Entity rating" |
+| `commons/…/connectedApps/signers/NostrSignerPermissionLedger.kt:244` | addressable re-sign list |
+| `amethyst/…/relays/KindDisplayName.kt` | localized name + `strings.xml` |
+| `quartz/…/utils/EventFactoryIsKnownKindTest.kt` | assert `isKnownKind(34259)` |
+
+---
+
+## 4. `LocalCache` ingest
+
+Today the event is **dropped**: unknown kind ⇒ bare `Event` ⇒ the `else` at
+`LocalCache.kt:3886` logs `"Event Not Supported"` and returns `false`. It never
+becomes a `Note`, so no amount of UI work would show it.
+
+Add `is EntityRatingEvent,` to the addressable group that dispatches to
+`consumeBaseReplaceable` at `LocalCache.kt:3799`. One line. `consumeBaseReplaceable`
+already handles addressable supersession, so the "one rating per author per
+target" replaceable semantics come for free.
+
+### Do **not** add a `computeReplyTo` branch in v1
+
+`computeReplyTo` (`LocalCache.kt:1268`) falls through to `emptyList()` for
+unknown types, so `Note.replyTo` stays empty and `Note.isNewThread()`
+(`commons/…/model/Note.kt:1364`) returns **true**. That is what we want: the
+rating renders as a top-level card in the New Threads tab.
+
+This is the `HighlightEvent` precedent — a highlight also carries `a`/`e` to its
+source and also has no `computeReplyTo` branch; it renders the source inline
+instead.
+
+The trade-off is explicit: without a `computeReplyTo` branch the rating does
+**not** appear in the rated publication's thread view or reply count. Adding one
+later moves it *out* of New Threads (because `isNewThread()` flips false) unless
+`HomeNewThreadFeedFilter` is taught an exception. Decide once; v1 picks feed
+visibility, because that is the stated goal.
+
+---
+
+## 5. Feed visibility — three gates, all must open
+
+This is the part that is easy to half-do. An event only reaches the Home feed if
+**all three** of these pass. Verified by reading each file.
+
+### Gate 1 — the REQ must ask for the kind
+
+The kind lists are duplicated across five top-nav strategies. Add
+`EntityRatingEvent.KIND` to `HomePostsNewThreadKinds2` in:
+
+- `commons/…/relayClient/home/nip65Follows/FilterHomePostsByAuthors.kt:83`
+- `commons/…/relayClient/home/nip01Core/FilterHomePostsByHashtags.kt`
+- `commons/…/relayClient/home/nip01Core/FilterHomePostsByGeohashes.kt`
+- `commons/…/relayClient/home/nip01Core/FilterHomePostsByGlobal.kt`
+- `commons/…/relayClient/home/nip72Communities/FilterHomePostsFromCommunities.kt`
+
+(`Kinds2` rather than `Kinds1` — `Kinds1` is already at 16 kinds and the two
+lists exist to keep each REQ's kind array bounded.)
+
+### Gate 2 — a `HomeFeedType` group
+
+`commons/…/model/HomeFeedType.kt` is the Settings › Home toggle registry; its
+`kinds` drive both the REQ strip (`HomeOutboxEventsEoseManager.removeDisabledHomeKinds`)
+and the DAL filter. Add:
+
+```kotlin
+RATINGS("ratings", listOf(EntityRatingEvent.KIND)),
+```
+
+`code` is the on-disk identifier — never rename it. `HomeFeedTypeTest.kindsAreDisjointAcrossTypes`
+enforces that no two groups claim a kind, so 34259 must appear exactly once. Add
+a string for the toggle label in `HomeTabsSettingsScreen`.
+
+### Gate 3 — the DAL must accept it
+
+`amethyst/…/home/dal/HomeNewThreadFeedFilter.kt`, two edits:
+
+1. **`ADDRESSABLE_KINDS`** (:108) — required. `feed()` scans `LocalCache.notes`
+   only for `kind < 10000` ("Avoids processing addressables twice"), so an
+   addressable kind that is not in this list is invisible no matter what else is
+   configured.
+2. **`acceptableEvent`** (:141) — add `noteEvent is EntityRatingEvent` to the
+   type disjunction.
+
+Mirror both in `HomeConversationsFeedFilter.kt` only if we later add the
+`computeReplyTo` branch; not in v1.
+
+Desktop has its own copy in `desktopApp/…/feeds/DesktopFeedFilters.kt` — out of
+scope here, but note it so the two don't silently diverge.
+
+### Anti-spam gate
+
+jumble drops kind-34259 events with no `d` tag on ingest. Ours is weaker-risk
+(addressable ⇒ a `d`-less event occupies exactly one slot per author), but a
+rating with no resolvable target is unrenderable. Reject in `acceptableEvent`:
+`targetAddress() != null || targetEventId() != null`.
+
+---
+
+## 6. Rendering
+
+New `amethyst/src/main/java/…/ui/note/types/EntityRating.kt`:
+
+```kotlin
+@Composable
+fun RenderEntityRating(note: Note, accountViewModel: AccountViewModel, nav: INav)
+```
+
+Layout, modelled on `Classifieds.kt` (compact addressable card) + `Highlight.kt`
+(inline source resolution):
+
+```
+┌──────────────────────────────────────────────┐
+│ ★★★★★                            [books]     │   stars + mark chip
+│ ┌──────────────────────────────────────────┐ │
+│ │ 📕 Wuthering Heights                     │ │   target card, clickable
+│ │    by @emilybronte                       │ │   ← LoadAddressableNote
+│ └──────────────────────────────────────────┘ │
+│ This is my very favorite book. The fast-     │   content, TranslatableRichTextViewer
+│ paced and mysterious plot …                  │
+└──────────────────────────────────────────────┘
+```
+
+- Target resolution: `LoadAddressableNote(targetAddress(), …)` — same helper
+  `RenderPostApproval.kt:61` and `Attestation.kt` use.
+- **Title fallback while (or if) the target never loads:** derive a label from the
+  coordinate's `d` (`wuthering-heights` → "Wuthering Heights"), as jumble's
+  `publicationTitleHintFromRatingEvent` does. Without this the card is a row of
+  stars attached to nothing — see §7.
+- Unknown/absent `m`: render stars + comment + a generic `nostr:` link to the
+  target. The kind is generic; the card must degrade, not blank.
+- Dispatch: add `is EntityRatingEvent -> RenderEntityRating(...)` to
+  `NoteCompose.kt`'s render `when`, **before** the `else` at :1658 (which
+  currently routes unknown kinds to `RenderTextEvent`).
+
+### The star icons need a font change
+
+`MaterialSymbols.kt:233-234` defines **both** `Star` and `StarBorder` as
+`\uF09A` — the same codepoint. Filled and outline stars are currently
+indistinguishable (which also means `FavoriteAlgoFeedToggle.kt:90/97` and
+`RelayGroupDiscoveryScreen.kt:400` are drawing the same glyph for on and off
+today).
+
+A 3.5-of-5 star row needs three distinct glyphs. So:
+
+1. Give `StarBorder` its real outline codepoint and add `StarHalf`.
+2. Regenerate the subset — **mandatory**, per `.claude/CLAUDE.md`:
+   `./tools/material-symbols-subset/subset.sh`
+3. Commit the regenerated `material_symbols_outlined.ttf` with the
+   `MaterialSymbols.kt` change, or the new glyphs render as tofu.
+
+Fixing the duplicate is a small pre-existing-bug fix that rides along; call it
+out in the PR body since it changes two unrelated toggles' appearance.
+
+---
+
+## 7. The kind-30040 dependency
+
+The rated object here is a **kind-30040 NKBIP-01 publication index**. Amethyst
+has no class for 30040 either, so `LocalCache` drops it by the same `else` at
+:3886. `LoadAddressableNote` will therefore resolve to a permanently empty
+`Note`, and the target card in §6 will never show a real title.
+
+Two ways to close this, and they are separable:
+
+**(a) v1 — slug fallback only.** Ship §6's derived-title fallback and no 30040
+class. The card reads "Wuthering Heights" from the coordinate. Cheap, honest,
+and correct for the common case where the `d` is a slug. Fails softly (shows the
+raw identifier) when the `d` is a hash or an opaque id.
+
+**(b) Phase 2 — minimal `PublicationIndexEvent` (30040).** A `title`/`author`/`d`
+parser plus `consumeBaseReplaceable` wiring, so the target card shows the real
+title and links somewhere. **Explicitly not** the publication *reader* — 30040 is
+an index over kind-30041 sections, and rendering a book is a separate feature an
+order of magnitude larger than this one.
+
+Recommend shipping (a) in v1 and (b) as an immediate follow-up. Do **not** let
+(b)'s scope pull the reader in.
+
+---
+
+## 8. Out of scope for v1, and what each would cost
+
+| Deferred | Why | Rough shape |
+| --- | --- | --- |
+| **Publishing a rating** | Needs a compose surface (star picker + comment) and a "what am I rating" entry point, which does not exist until 30040 objects are browsable. The quartz builder DSL lands in v1 anyway, so this is UI-only later. | `NewPostScreen` variant + a rate action on the target card |
+| **Aggregate rollups** | Needs a per-target index in `LocalCache` (like the zap/reaction indices) plus a REQ by `#a`/`#d`. Meaningful only once there is a target screen to put the average on. | New index + `FeedMetadataCoordinator` assembler |
+| **Rating relays / profiles / hashtags** | The kind is generic and these marks are in the spec, but each needs its own target card and entry point. The event class supports them from day one. | Per-mark `RenderEntityRating` branch |
+| **Relay reviews (kind 31987)** | Same `rating` tag convention, also unsupported in Amethyst today. Sharing `stars()` between the two is the natural next step. | Reuse `tags/RatingTag.kt` |
+
+---
+
+## 9. Order of work
+
+1. **quartz** — `EntityRatingEvent` + tags + builder + `RatingMark`, with unit
+   tests covering all four `stars()` branches, the `d`-prefix strip, `a`-over-`d`
+   preference, and a round-trip of the real imwald event above as a fixture.
+2. **quartz registries** — `EventFactory`, `KindNames`, `isKnownKind` test.
+3. **LocalCache** — one line at :3799; test that the fixture becomes an
+   addressable `Note` and that a newer rating from the same author supersedes it.
+4. **Feed plumbing** — the three gates in §5, plus the `HomeFeedType` test update.
+5. **Icons** — codepoint fix + `subset.sh` + committed `.ttf`.
+6. **Rendering** — `EntityRating.kt`, `NoteCompose` branch, `@Preview` in
+   `ThemeComparisonColumn` (the convention every `ui/note/types/*.kt` follows).
+7. **Verify** — `./gradlew test`, then drive the real event end-to-end with
+   `amy` against `wss://pipe.imwald.eu/` (already a known-good relay in this
+   repo: `quartz/plans/2026-07-16-relay-limits.md`) to confirm ingest and
+   feed acceptance, not just unit-test green.
+8. `./gradlew spotlessApply`.
+
+Steps 1–3 are independently useful (they stop the drop and make the kind
+inspectable) and can merge before the UI lands.
+
+---
+
+## 10. Open questions for the maintainer
+
+1. **`m` vocabulary policy.** Render only known marks richly and fall back to a
+   generic card for the rest (proposed), or refuse to render unknown marks at
+   all? The generic fallback risks showing stars for a mark whose target we
+   cannot resolve.
+2. **Default-on or default-off.** `HomeFeedType.ALL` enables every group by
+   default. A brand-new, single-client, non-NIP kind arriving in everyone's Home
+   feed on upgrade is a defensible objection — say so and it ships default-off
+   with an explicit opt-in, at the cost of nobody discovering it.
+3. **Is 30040 worth it here**, or should ratings wait until publications are a
+   real feature? §7(a) makes v1 standalone, but a feed of star-ratings pointing
+   at books Amethyst cannot open is arguably not worth shipping alone.
+
+---
+
+## 11. What shipped, and where this plan was wrong
+
+Implemented on `claude/event-kind-34259-parsers-jocu9w`. Three things came out
+differently once the code was written; the sections above are left as they were
+so the reasoning is still legible, and this section is what is true.
+
+### 11.1 The star-icon claim in §6 was wrong
+
+§6 says `MaterialSymbols.Star` and `StarBorder` sharing `\uF09A` is a bug. **It
+is not.** Material Symbols expresses fill through the **FILL variable axis**, not
+through separate codepoints, so the upstream codepoint table maps `star`,
+`star_border`, `star_outline` *and* `grade` all to `f09a`. The duplicate in
+`MaterialSymbols.kt` is correct, and the toggles in `FavoriteAlgoFeedToggle.kt`
+and `RelayGroupDiscoveryScreen.kt` distinguish their states by tint, not glyph —
+also correct. Nothing there needed fixing.
+
+What is true: `star_half` **is** its own glyph (`e839`), and it was not in the
+subset. So the font change that actually shipped is one added symbol:
+
+```kotlin
+val StarHalf = MaterialSymbol("\uE839")
+```
+
+plus the regenerated `material_symbols_outlined.ttf` (241 codepoints, was 240).
+Filled vs empty stars are the same glyph at two tints — `primary` and
+`onSurfaceVariant`.
+
+**Corrected after review.** `MaterialSymbolPainter` originally drew the glyph as
+tinted text with no variable-axis control, so the first pass tinted an outline
+star and called it "filled" — five hollow outlines that read as an empty row.
+`87a44b97` added FILL-axis support to the painter and `aa54508e` switched the row
+to `filled = isOn`, which is the correct fix: an earned star is FILL=1, not a
+tint. Tint now only distinguishes earned from unearned, which is what it is
+good for.
+
+### 11.2 Gate 1 is one list, not five
+
+§5 says to add the kind to five parallel REQ kind lists. Only one was right:
+`HomePostsNewThreadKinds2`, which the Follows, Global and Relay top-nav
+strategies all share.
+
+The hashtag, geohash and community lists select by `t` / `g` / community-`a`
+tags. A rating carries none of those, so adding the kind there would widen every
+such REQ for zero possible matches. If ratings ever start carrying topics it is a
+one-line addition to each.
+
+### 11.3 §7 shipped as option (b)
+
+`PublicationIndexEvent` (kind 30040, NKBIP-01) is implemented — title, author,
+summary, image, type, version, topics and the ordered `a`-tag table of contents —
+so the rated publication resolves to a real title instead of a slug. The reader
+is **not** implemented, and kind 30041 sections are still unparsed, exactly as
+§7 said they should be.
+
+`titleOrIdentifier()` keeps the slug fallback from option (a) anyway, because the
+spec's mandatory `title` tag is missing from events in the wild.
+
+### 11.4 Everything else went as planned
+
+| Area | Where |
+| --- | --- |
+| Event classes | `quartz/…/experimental/ratings/`, `quartz/…/experimental/publications/` |
+| Registries | `EventFactory`, `KindNames`, `NostrSignerPermissionLedger` |
+| Ingest | `LocalCache.kt` addressable group (no `computeReplyTo` branch, per §4) |
+| Feed gates | `HomePostsNewThreadKinds2`, `HomeFeedType.RATINGS`, `HomeNewThreadFeedFilter` |
+| Settings | `home_content_type_ratings`, `HomeTabsSettingsScreen` |
+| Rendering | `amethyst/…/ui/note/types/EntityRating.kt` + `NoteCompose` branch |
+
+Tests: 44 new (27 in `quartz`, 7 ingest + 10 existing-suite in `amethyst`),
+covering all four branches of the `stars()` ladder, the `"1"` ambiguity, the
+`d`-prefix strip, `a`-over-`d` preference, addressable supersession in both
+directions, and the `isNewThread()` tripwire that guards §4's decision. Full
+suites green: quartz 4491, commons 1788, amethyst 1415.
+
+`stars()` gained one branch the plan did not anticipate: an `s` tag outside
+1..5 falls **through** to `rating` rather than winning, so a bogus `s` cannot
+shadow a usable score.
+
+### 11.5 Still open
+
+§10's three questions are unanswered and the code takes the defaults:
+
+1. Unknown marks render generically (stars + review + target link).
+2. `RATINGS` is **default-on**, because `HomeFeedType.ALL` enables everything and
+   opting one entry out of that would be a special case. One line in
+   `HomeFeedType.ALL` changes it.
+3. Publishing, aggregate rollups, and the 30041 reader remain unbuilt. The
+   `EntityRatingEvent.build()` DSL exists and is tested, so publishing is UI-only
+   work whenever a "rate this" entry point exists.

+# Local search as `filter(Filter)` — retiring the bespoke `find*StartingWith` scans
+
+_Status: **steps 1–6 shipped**; see §8 for what landed, what changed on contact with the code, and
+what is deliberately left. The three decisions in §2 were taken as recommended._
+
+## 0. The shape of the thing
+
+`LocalCache` today answers two different kinds of question with two unrelated mechanisms:
+
+- **Generic**, already built: `filter(filter: Filter): SortedSet<Note>`, plus `observeNotes`,
+  `observeEvents`, `observeNewEvents` and an indexed observable registry. Every feed filter in the
+  app goes through it.
+- **Bespoke**, five hand-written scans in `CacheSearch`: `findNotesStartingWith`,
+  `findUsersStartingWith`, and three channel variants.
+
+The generic path cannot answer a search because **`FilterMatcher.match` has no `search`
+parameter**. It takes `ids, authors, kinds, tags, tagsAll, since, until` and nothing else, so a
+`Filter` carrying only NIP-50 `search` matches *every* event. That one hole is the entire reason
+`CacheSearch` exists as a separate mechanism.
+
+Quartz already owns the missing half: `SearchableEvent.indexableContent()` (126 classes),
+`SearchQuery.parse` / `stripExtensions` for the wire grammar, and two reference consumers — the
+SQLite store (FTS5, bm25 then `created_at`) and the filesystem store (`FsSearchTokenizer`).
+
+So this is not "abandon the model". It is: close one hole in the matcher, move viewer policy out
+of the matcher where it never belonged, and delete five scans.
+
+**The payoff is bigger than the tidy-up.** Once local search is `filter(Filter)`, the search field
+feeds the *same* `SearchFilterBuilder.build(query)` output to both the relay REQ and the local
+cache. `from:`, `to:`, `since:`, `#t`, `group:` then work identically local and remote. Today they
+work only on desktop and only against relays; on Android the token chips are cosmetic, because
+`SearchBarViewModel` puts the raw text (tokens and all) into the NIP-50 `search` string. This
+refactor and that bug are one fix.
+
+## 1. What must not change
+
+`CacheSearch` does five things a `Filter` cannot express. Three are real requirements; two are
+misplacements.
+
+Requirements:
+- **Bech32 / hex id entry.** `decodeEventIdAsHexOrNull(text)` → resolve the note, preferring the
+  addressable note when it is the same event. This is a *lookup*, not a search, and stays as a
+  pre-step that builds `Filter(ids = …)`.
+- **Viewer policy.** `isHiddenFor(hiddenUsers)`, `excludeNoteEventFromSearchResults(note)`, and
+  skipping `isContentEncoded()` events.
+- **Tag-value matching** with an excluded-tag-name list (`excludedTagNamesFromSearch`).
+
+Misplacements — these belong outside the filter:
+- Viewer policy is not a wire concept. A relay has no idea what you have muted. It becomes a
+  composed predicate, not a filter field (§3.2).
+- Relevance ordering has nowhere to live today: `filter()` returns
+  `toSortedSet(CreatedAtIdHexComparator)` — recency only, where the SQLite store ranks bm25 first.
+
+## 2. Open decisions
+
+### 2.1 What "matches" means locally
+
+`findNotesStartingWith` does `content.contains(text, true)` — **substring**, despite the name. The
+stores tokenize. `"itcoin"` finds "bitcoin" today and would not under a tokenizer.
+
+| | Substring (today) | Token (the stores) |
+| --- | --- | --- |
+| Behaviour preserved | yes | no — mid-word queries stop matching |
+| Matches what relays return | no | yes |
+| Cost | one scan per field | tokenize per field, or an index |
+| Reuse | none | `FsSearchTokenizer`, but it lives in `jvmMain` and would need promoting to `commonMain`/`jvmAndroid` |
+
+Recommendation: **keep substring for v1** and treat tokenization as a separate, later change with
+its own before/after. Local and remote results already differ (one is FTS5+bm25, the other a linear
+scan); pretending otherwise is not worth a behavioural regression in the same PR that moves the
+plumbing. Revisit when local search gets a real index.
+
+### 2.2 Where viewer policy is applied
+
+Recommendation: `LocalCache.filter(filter: Filter, predicate: (Note) -> Boolean = { true })`, with
+the mute/kind/encoding rules extracted from `CacheSearch` into a reusable
+`NoteVisibility(hiddenUsers)` predicate. Every feed benefits, not just search, and the wire type
+stays a wire type.
+
+### 2.3 Relevance ordering
+
+`SearchSortOrder.RELEVANCE` exists app-side (`SearchResultSorter`). Recommendation: leave ranking
+above `filter()`, keep `filter()` recency-ordered, and document that local ordering is *not*
+bm25 parity. If relevance parity is wanted later it needs a score out of the matcher, which the
+`Boolean` return cannot carry — a reason not to paint ourselves into `Boolean` (§4.3).
+
+## 3. Does touching `FilterMatcher` interfere with, or slow down, current callers?
+
+Two separate questions. The speed answer is "no, if done right". The correctness answer is "yes,
+and that is the risk".
+
+### 3.1 Correctness — the actual hazard
+
+`Filter.match` has wide reach: 33 feed filters under `amethyst/.../dal/`, `FilterIndex`, and
+geode's `MirrorWorker`. Today any filter carrying `search` matches on its NIP-01 fields alone.
+The moment the matcher honours `search`, every one of those newly narrows.
+
+Most never set `search`. But "most" is not "none", and a relay mirroring less than it used to is a
+bad way to find out.
+
+**Mitigation — do not flip the default first.** Land the search capability as an opt-in the
+LocalCache search path composes explicitly (a `SearchMatcher`, or a `matchIncludingSearch`
+entry point). Audit every construction site of a `Filter` that reaches `match`, confirm which
+carry `search`, then make it the default in a second, separate commit that can be reverted alone.
+
+### 3.2 Speed — the added check is free, but the loop around it is not
+
+A trailing `if (search != null && !matchesSearch(event, search)) return false` costs **one
+reference comparison** for every existing caller. Checked last, after the cheap field rejects, it
+is not measurable. That part is safe.
+
+The problem is what a search scan *reveals*. `FilterMatcher.match` allocates inside the per-event
+loop today:
+
+```kotlin
+tags?.forEach { tag ->
+    val valueSet = tag.value.toSet()              // a Set per event, per tag key
+    if (!event.tags.any { … }) return false       // stdlib any → an iterator per event
+}
+tagsAll?.forEach { tag ->
+    val eventTagValueSet =
+        event.tags.mapNotNullTo(mutableSetOf()) { … }  // a MutableSet + full tag scan per event
+    …
+}
+```
+
+These are pre-existing and tolerable at feed-rebuild rates. They are not tolerable on a
+full-cache scan per keystroke — and `SearchFilterBuilder` makes them worse, because
+`ScopeIds.tagValues` emits up to four spellings per hashtag, so `toSet()` runs on a 4-element list
+per note.
+
+`CLAUDE.md`'s hot-path rule already says what to use: `fastAny` / `fastForEach` from
+`nip01Core/core/TagArray.kt`, not the stdlib collection operators.
+
+**The structural fix — hoist per-filter work out of the per-event loop.** Everything derived from
+the `Filter` (the value sets, the tokenized or `DualCase`-folded search terms) is loop-invariant
+and is currently recomputed per event. A prepared matcher built once per query and reused across
+the scan removes all of it:
+
+```kotlin
+class PreparedFilter(filter: Filter) {          // built once per query
+    private val tagValueSets = …                // Sets built once, not per event
+    private val terms = …                       // DualCase terms folded once
+    fun match(event: Event): Boolean            // allocation-free
+}
+```
+
+This is a win for every existing caller, not just search — feed rebuilds pay the same per-event
+allocations today. **Recommendation: land the prepared matcher first, as a pure no-behaviour-change
+commit with the existing tests as the guard, before adding `search` at all.**
+
+## 4. The indexable surface — do not build strings
+
+### 4.1 The current cost
+
+Of the 126 implementations:
+
+| Shape | Count | Allocation per call |
+| --- | --- | --- |
+| `listOfNotNull(…).joinToString("\n")` | 86 | list + `StringBuilder` + joined `String` |
+| `content` | 28 | none |
+| JSON-parsing (kind 0, channels, stalls) | rest | **re-parses JSON every call** |
+
+Kind 0 is the worst case and the most searched: `contactMetaData()` has no cache, so it runs
+`JsonMapper.fromJson<UserMetadata>(content)` on every invocation. Calling `indexableContent()`
+across the cache per keystroke would parse every profile, per keystroke.
+
+For a write path — index once on insert — that cost is irrelevant, which is why it looks the way
+it does. For a read path over the whole cache it is disqualifying. `indexableContent()` is the
+right API for the stores and the wrong API for matching.
+
+### 4.2 The precedent already in the tree
+
+`UserMetadata.anyPropertyContains(terms: List<DualCase>)` is exactly the right shape, and already
+exists for kind 0:
+
+```kotlin
+fun anyPropertyContains(terms: List<DualCase>): Boolean =
+    name?.containsAny(terms) == true ||
+        displayName?.containsAny(terms) == true ||
+        about?.containsAny(terms) == true || …
+```
+
+No list, no join, `||` short-circuits on the first hit, and `DualCase` folds each term's cases
+**once** rather than per comparison. The proposal is to generalise this, not to invent something.
+
+### 4.3 Proposed surface
+
+```kotlin
+fun interface IndexableFieldVisitor {
+    /** @return false to stop walking — a hit on the title need not touch the body. */
+    fun visit(field: String?): Boolean
+}
+
+interface SearchableEvent {
+    fun forEachIndexableField(visitor: IndexableFieldVisitor)
+
+    /** Kept for the stores. Derived, so its output stays byte-identical to today's. */
+    fun indexableContent(): String
+}
+```
+
+An implementation carries no collection at all:
+
+```kotlin
+override fun forEachIndexableField(v: IndexableFieldVisitor) {
+    if (!v.visit(name())) return
+    if (!v.visit(description())) return
+    v.visit(content)
+}
+```
+
+Notes on the shape:
+
+- **`fun interface`, not a lambda parameter.** An interface method cannot be `inline`, so a lambda
+  at the call site would allocate. A `fun interface` instance is created **once per scan** and
+  reused for every event, carrying the loop-invariant query terms on itself. Zero allocation per
+  event, which is the whole point.
+- **Nulls pass through**, so implementors never need `listOfNotNull`.
+- **`Boolean` return for short-circuit.** Caveat: it forecloses scoring (§2.3). If bm25-ish
+  relevance is ever wanted locally, this wants to be an accumulator instead. Worth deciding now,
+  cheaply, rather than re-touching 126 classes later.
+- **Rejected alternative: `fun indexableFields(): List<String>`.** Simpler, but still allocates a
+  list per event and cannot short-circuit. Acceptable fallback if the visitor proves awkward for
+  some kind, but it is strictly worse.
+
+### 4.4 The compatibility constraint
+
+`indexableContent()` **must survive with byte-identical output**. The SQLite and filesystem stores
+index through it, and `references/searchable-kinds.md` (the `searchable-events` skill) is mirrored
+by external engines — the Vespa-backed store's `SearchExtractors` tracks that table at pin bumps.
+A changed body means stale results downstream and a `reindexFullTextSearch()` for existing
+databases.
+
+If the default `indexableContent()` is *derived* from `forEachIndexableField` with the same field
+order and separator, output is identical, the table stays valid, and no reindex is needed. Watch
+the separator: most kinds join with `"\n"`, a handful of metadata-ish kinds with `" "`, so the
+derived default needs the separator as a per-kind property rather than a hard-coded `"\n"`.
+
+Per that skill's mandatory-maintenance rule: any change here updates
+`references/searchable-kinds.md` in the same PR.
+
+### 4.5 JSON kinds still need a cache
+
+Even with the visitor, kind 0 re-parses on every event visited. Either cache the parsed
+`UserMetadata` on the event, or route kind-0 matching through the existing
+`UserMetadata.anyPropertyContains` against `LocalCache`'s already-parsed `User.metadataOrNull()`
+— which is what `findUsersStartingWith` effectively does today, and is the cheaper answer.
+
+## 5. Sequencing
+
+Each step is independently revertible; none but the last changes user-visible behaviour.
+
+| # | Step | Behaviour change |
+| --- | --- | --- |
+| 1 | `PreparedFilter` — hoist per-filter work, swap stdlib ops for `fast*` (§3.2) | none |
+| 2 | `forEachIndexableField` + derived `indexableContent()`; update the kinds table (§4) | none |
+| 3 | Search matching as an opt-in entry point, substring semantics (§2.1) | none — nothing calls it yet |
+| 4 | `filter(filter, predicate)` + `NoteVisibility` extracted from `CacheSearch` (§2.2) | none |
+| 5 | `find*StartingWith` → filter builders; delete the bespoke scans | parity-tested |
+| 6 | `SearchBarViewModel` feeds `SearchFilterBuilder` output to *both* relay and cache | **the Android fix** |
+| 7 | Audit `search`-carrying filters, then make the matcher honour it by default (§3.1) | audited |
+
+## 6. Parity harness
+
+`desktopApp/src/jvmTest/.../cache/FindUsersTest.kt` already covers `findUsersStartingWith` in 8
+tests and is a ready-made before/after gate. There is no equivalent for
+`findNotesStartingWith`; write one against the current implementation **before** step 5, so the
+rewrite is measured against recorded behaviour rather than against intent.
+
+Call sites to migrate: `SearchBarViewModel`, `UserSuggestionState`, `UserSearchEngine`,
+`BuzzNewDmViewModel`, `AgentAttestationScreen`, `ICacheProvider`, `SearchBarState`, and desktop's
+`DesktopLocalCache`, `ChatPane`, `ComposeNoteDialog`.
+
+## 7. Related
+
+- `event-store-semantics` skill — the store contract the local matcher should not contradict;
+  query-side rules are STORE-S01…S06. Read it before fixing the semantics in step 3.
+- `searchable-events` skill — the indexing surface, the authoritative kind table, and the
+  mandatory-maintenance rule for §4.4.
+- `2026-09-07` search-field work (`SearchTokenizer` / `SearchFilterBuilder` in `commons/search/`)
+  — produces the `Filter`s step 6 consumes.
+
+
+## 8. What actually shipped
+
+Steps 1–6 landed. Two things changed on contact with the code, both for the better:
+
+**Step 7 is moot, and the blast radius never opens.** The plan assumed local search needed
+`FilterMatcher` to honour `search`, which would have narrowed every filter carrying one — 33 feed
+filters, `FilterIndex`, geode's `MirrorWorker` — and needed an audit before flipping. It does not.
+`LocalCache.filter` grew a **predicate** parameter instead, and search composes an
+`EventSearchMatcher` into it. `FilterMatcher` is untouched, so nothing else can change behaviour.
+The predicate is also where viewer policy went (§2.2), so one parameter answers both.
+
+**Step 1 turned out to be a pure win with no search in it.** `FilterMatcher` was allocating three
+ways per event; fixing that needed no new API and pays for all 33 existing callers. It is pinned by
+a differential test that keeps the old implementation as an oracle and fuzzes 20,000 random
+event/filter pairs against it.
+
+**Step 2 is scoped, not universal.** `forEachIndexableField` has a default that falls back to
+`indexableContent()` — already free for the ~28 kinds whose indexable content is `content` itself —
+and only the kinds local search actually scans override it (text notes, long-form, wiki,
+highlights, classifieds, live activities, community definitions). The remaining ~79 joining
+implementations still allocate on the read path, which costs nothing until something scans them.
+A test pins every override's fields to rejoin to `indexableContent()` byte-for-byte, so the
+externally-mirrored kind table stays valid and no reindex is needed.
+
+### Deliberately not done
+
+- **`findUsersStartingWith` and the three channel finders stay.** They are name-prefix lookups over
+  users and channels, not event filters; forcing them through a `Filter` would be worse, not
+  better. The plan's framing ("retire the bespoke scans") was too broad — only the *note* search is
+  filter-shaped.
+- **`findNotesStartingWith` stays, on one narrow path.** It matches `idHex.startsWith(text)` and
+  resolves bech32 pointers, neither of which is content and so neither reachable through a
+  filter's `search`. Text that could name an event — a bech32 pointer, or ≥8 hex characters — is
+  routed to it; everything else goes through the filters. The first cut fell back to it whenever
+  the filter path came up empty, which made every zero-result keystroke scan the cache twice.
+- **No characterization test for `findNotesStartingWith`.** The parity harness §6 asked for was not
+  written; the id path it guards is now the only thing still using that scan, and it is unchanged.
+  Worth writing if that path is ever touched.
+
+### Semantics that changed
+
+Local text matching is now **terms ANDed**, each a case-insensitive substring, where it was one
+literal phrase. A single-word query — the common case — is identical; `bitcoin lightning` now finds
+notes carrying both words rather than only that exact phrase, which is what the relay already
+returned for the same string. Ordering stays recency (§2.3): no local relevance score exists, and
+`EventSearchMatcher` answers only yes or no.

+# DVM heartbeat liveness — only show DVMs with a fresh kind-11998 heartbeat
+
+_Status: **implemented** (Android; desktop wiring deliberately out of scope — §8)._
+
+## 0. The shape of the thing
+
+Amethyst shows Data Vending Machines (DVMs) in three places: the Discover "Content" tab
+(kind 31990 NIP-89 announcements advertising kind 5300), DVM feeds pinned to the top-nav
+(`FavoriteAlgoFeedsOrchestrator`), and the per-DVM content-discovery screen. Today all of
+these treat every announced DVM as alive, forever — a DVM that went down months ago still
+renders as a usable feed.
+
+DVM operators are now sending a **heartbeat event (kind 11998) every 300 seconds**. The
+event is plain-text (`content = "Alive and kicking"`) with three tags:
+
+- `status` — free-text status line (e.g. "My heart keeps beating like a hammer")
+- `d` — the DVM's **NIP-89 DTAG**, tying the heartbeat to the announcement's address
+- `expiration` — `createdAt + 300` (NIP-40), so relays drop the beat once the next one lands
+
+Kind 11998 sits in the replaceable range (10000–19999), so relays keep only the latest beat
+per author. There is no NIP for this yet — the shape above comes from the operator-side
+builder and is treated as the wire contract.
+
+The feature: **a DVM counts as alive only if its latest heartbeat is at most 900 seconds
+old** (one missed 300s beat plus slack). Dead DVMs disappear from the Discover list; pinned
+feeds and the detail surface show an offline state instead.
+
+## 1. Decisions taken
+
+1. **Approach: cache-backed heartbeats.** The heartbeat is a real event class stored through
+   the standard replaceable path in `LocalCache` (newest per address, standard invalidation).
+   Rejected alternatives: a side-state registry (duplicates invalidation plumbing) and
+   regular-note storage (no address matching, pollutes the notes index).
+2. **Scope: all three surfaces** — Discover list (hide), pinned feeds (offline state, chip
+   stays), DVM detail screen (offline banner, requesting still allowed). The manage screen
+   (`FavoriteAlgoFeedsListScreen`) also gets the badge.
+3. **Pinned chips stay when offline** — the user pinned them deliberately; they gray out
+   with an offline badge rather than vanishing, and tapping still opens the feed.
+4. **Threshold: 900 seconds** (raised from the original 420 after field testing: beats arrive every 300s, and a 420s window tolerated barely one delivery hiccup, dropping live DVMs in oscillations). Exactly 900s old counts as fresh.
+5. **Strict from cold start.** No grace period: the Discover list starts empty and fills
+   within ~1–2s as heartbeat REQs return (same behavior as the existing 31990 load).
+
+## 2. Event model (quartz)
+
+New `quartz/.../nip90Dvms/dvmHeartbeat/DvmHeartbeatEvent.kt`:
+
+- `class DvmHeartbeatEvent(...) : BaseAddressableEvent(...)`, `KIND = 11998` — the codebase
+  convention for 10xxx events with real `d` tags (e.g. `FollowListEvent`), so `dTag()` /
+  `address()` / `addressTag()` come from the base. The cache address is
+  `Address(11998, dvmPubkey, dTag)`, the exact mirror of the announcement's
+  `Address(31990, dvmPubkey, dTag)`.
+- Accessors: `status()`, and `expiration()` via the existing NIP-40 extension.
+- `MAX_AGE_SECONDS = 900` and `isFreshAt(now)` live in quartz too (commons imports them).
+- Registered in `EventFactory` (kind → constructor) and allowlisted in
+  `EventFactoryKindRangeTest.knownDTagReaders`: the `d` tag keys the client-side address
+  while relay storage stays plain-replaceable per the kind range.
+
+## 3. Cache consumption (LocalCache)
+
+One routing line in `LocalCache.justConsumeInnerInner`: `is DvmHeartbeatEvent ->`
+`consumeBaseReplaceable(event, relay, wasVerified)`. This yields newest-per-address
+replacement, relay tracking, and `LocalCacheFlow` invalidation for free. Unlisted kinds fall
+into the `else` branch and are rejected, so the routing line is mandatory.
+
+Stale beats simply sit at their address until overwritten; the age check (§4) makes them
+invisible. The cache pruner removes old entries on its own schedule.
+
+## 4. Freshness core (amethyst)
+
+Small helper file in `amethyst/.../model/` (the threshold constant itself lives in quartz):
+
+- `LocalCache.dvmHeartbeatOf(appDef: AppDefinitionEvent): DvmHeartbeatEvent?` — address
+  lookup `Address(DvmHeartbeatEvent.KIND, appDef.pubKey, appDef.dTag())`
+- `DvmHeartbeatEvent.isFreshAt(now: Long): Boolean` — `createdAt >= now - 900`
+- `@Composable fun rememberDvmHeartbeatFresh(address: Address, accountViewModel: AccountViewModel): State<Boolean>` —
+  as built (uniform-strict ruling): returns true while the DVM has a heartbeat at most 900s
+  old; an unresolved/absent beat counts as offline (`false`) on every surface. The returned
+  `State` identity is stable for the lifetime of the call site (one unconditional
+  `rememberUpdatedState`), so callers may capture it across recompositions. Composable-scoped
+  subscription (§5) + staleness re-check tick (§6), shared by every surface that renders
+  liveness.
+
+## 5. Subscriptions
+
+**Discover screen — all DVM heartbeats.** In
+`commons/.../relayClient/discover/nip90DVMs/SubAssemblyHelper.kt`, `makeContentDVMsFilter`
+unconditionally appends one filter for every top-filter variant:
+`kinds = [11998], since = TimeUtils.now() - 900` — no authors, no tags, scoped to the same
+relay set as the 31990 REQs. It deliberately ignores the 31990 `since`-cursor (heartbeats
+are a rolling window, not a cursor stream — the cursor would miss re-opened tabs after the
+beats expired). It rides the existing assembler lifecycle: subscribes on entering Discover,
+closes on leaving.
+
+**Per-surface — pinned chips, home banner, detail screen.** `rememberDvmHeartbeat` opens a
+tiny composable-scoped subscription: `kinds = [11998], authors = [dvm pubkey], limit = 1,
+since = now - 900`. The home top-bar chips live for the whole session, so they double as
+the session-scoped watcher for pinned DVMs. Traffic is negligible (a few pinned DVMs ×
+1 event / 5 min).
+
+**Outbox fetcher (added after field testing).** The global REQ above only sees beats that
+reach the *user's* discovery relays — but DVMs publish beats to their own write relays, and
+relays don't gossip, so alive DVMs whose beats never overlap the user's relay set stayed
+invisible (their detail screens proved the beats existed on the outbox). `DiscoveryDvmHeartbeatSubAssembler`
+joins the discovery assembler group and, while Discover is composed, batches the cached
+content-discovery announcements' authors per **DVM outbox relay** (`kinds = [11998],
+authors = [those pubkeys], since = now - 900`, coverage-ranked and capped at 12 relays;
+authors with unknown outboxes/hints rely on the global REQ as fallback). It re-issues when
+the cached announcement set or the NIP-65 relay lists move.
+
+The announcement source MUST be the **ungated cache scan**
+(`LocalCache.cachedDvmAnnouncements` — every cached k=5300 announcement, newest first, capped
+at 100), not the gated feed list. Sourcing from the gated list is a death spiral: a DVM
+leaves the gated list the moment its beat ages out, the fetcher would stop covering it, and
+no beat would ever arrive to bring it back — any transient staleness becomes a permanent
+drop. The relay lookup unions the author's NIP-65 outbox with the cached relay hints for the
+author (the same mix the event finder's `potentialRelaysToFindAddress` uses).
+
+## 6. Invalidation — closing the two silent gaps
+
+1. **A new heartbeat does not re-rank the list.** The additive feed path
+   (`FeedContentState.updateFeedWith`) re-filters only the *new* notes, and a heartbeat
+   note is never a list row — the affected 31990 card would not be re-evaluated. Fix: in
+   `AccountFeedContentStates.updateFeedsWith`, branch on
+   `newNotes.any { it.event is DvmHeartbeatEvent }` → `discoverDVMs.invalidateData()`
+   (full rebuild re-runs the freshness check on every announcement); otherwise the normal
+   additive path.
+2. **Expiry produces no event.** A 60s timer collector in `AccountFeedContentStates`
+   (alongside the existing `scope.launch { flows.collect { … } }` observers) calls
+   `discoverDVMs.invalidateData()` every minute. The rebuild is a cheap scan (≤ a few
+   hundred 31990s) and `refreshSuspended()` no-ops when the list is unchanged. Composables
+   using `rememberDvmHeartbeatFresh` tick on a 30s cadence internally.
+
+## 7. UI surfaces
+
+1. **Discover "Content" tab** — `DiscoverNIP89FeedFilter.acceptApp` adds
+   `dvmHeartbeatOf(noteEvent)?.isFreshAt(now) == true`. No fresh beat → card hidden.
+2. **Pinned top-nav chips** — chip stays; when the heartbeat is stale or absent the chip is
+   grayed out with a small offline dot appended to its label. Tapping still opens the feed.
+3. **Pinned feed view** — new branch in `HomeAlgoFeedStatusBanner`: when the selected
+   pinned feed's heartbeat is stale, show an offline banner above the last known content,
+   shown *even when content exists* (the current banner only handles empty/error states).
+   Single-feed and all-feeds variants both covered.
+4. **DVM detail screen** (`DvmContentDiscoveryScreen`) — same offline banner; requesting is
+   still allowed (informational, not a block).
+5. **`FavoriteAlgoFeedsListScreen`** — offline badge per row so users can spot dead pins.
+6. New English string resources (`dvm_offline`, `dvm_offline_banner`); translations flow
+   via Crowdin.
+
+## 8. Edge cases (accepted limitations)
+
+- Heartbeat without a `d` tag → cache address dTag `""` → matches nothing → DVM hidden
+  (strict; the wire contract always sends `d`).
+- Device/DVM clock skew > 15 min → wrongly hidden (inherent to timestamp-based liveness).
+- DVM beats that never reach the relays we query → shows offline (that is the feature).
+- One keypair running multiple DVMs → relays keep only the latest beat per (kind, author);
+  per-d-tag cache slots help only across relays. Most DVMs use one key each.
+- **Desktop app: out of scope this round.** The commons subscription helper is shared-ready
+  and the desktop relay assembler will pick up heartbeat REQs harmlessly (cache fills,
+  nothing renders), but all UI wiring is Android-only.
+
+## 9. Testing
+
+- **quartz**: parse/build `DvmHeartbeatEvent` — `dTag()` override, `statusTag()`,
+  `expiration()`, address assembly.
+- **amethyst**: `DiscoverNIP89FeedFilter.acceptApp` matrix — no beat → reject; fresh beat →
+  accept; 421s-old beat → reject. The `updateFeedsWith` heartbeat branch triggers a full
+  rebuild. `isFreshAt` boundary (900s fresh, 901s stale).
+- Verify with `./gradlew :quartz:test :amethyst:test`, then `./gradlew spotlessApply`.

+ * Upstream regression test for androidx.compose.foundation:foundation-layout.
+ *
+ * A `WindowInsetsAnimation` that is prepared and started but never ended — which is what a
+ * cancelled IME animation looks like — leaves `InsetsListener.runningAnimation` set forever.
+ * `onApplyWindowInsets` then matches neither of its two branches, so `composeInsets.update()`
+ * is never called again and `WindowInsets.ime` is dead for the life of the window.
+ *
+ * Introduced in 1.4.0 (absent in 1.3.0, where `onApplyWindowInsets` updated unconditionally
+ * once `onStart` had cleared `prepared`). Still present in 1.12.0 and 1.13.0-alpha01. The
+ * compensating self-heal (`view.post(this)` -> `run()`) is scoped to `SDK_INT == R`, so on
+ * API 31+ nothing clears the flag; `WindowInsetsHolder.resetState()` only runs when the
+ * holder's accessCount transitions 0 -> 1, which never happens in an app whose shell always
+ * reads insets.
+ *
+ * Filed upstream as b/552500419.
+ *
+ * [aCancelledImeAnimationMustNotWedgeTheAnimatedInset] FAILS on every version from 1.4.0 on, so it
+ * is [Ignore]d to keep CI green. It is not a test of Amethyst code — it is the upstream repro we
+ * attached to the bug. **Re-run it by hand after every Compose upgrade**: when it passes, the
+ * upstream fix has landed and [com.vitorpamplona.amethyst.ui.insets.SafeImeInsets] can be retired.
+ *
+ * [theAnimationTargetSurvivesTheWedge] documents the asymmetry that makes a workaround possible
+ * and is expected to PASS — `updateImeAnimationTarget` is called outside the guard. It stays
+ * enabled, because it guards the premise [com.vitorpamplona.amethyst.ui.insets.SafeImeInsets]
+ * depends on: if a future Compose release stopped keeping `imeAnimationTarget` current, our
+ * fallback would silently start reading a dead value too.

+ * revoked-but-still-signed record in a fresh kind `448` at any later epoch, and
+ * a client that forgot the tombstone would accept it and start waking a device

+ * bounded by any wall clock, `owner_ts` or epoch count — a key is cleared only
+ * by a strictly newer registration, or by its leaf leaving the group.
+ *
+ * Not encrypted, deliberately: the file holds tokens already encrypted to a
+ * notification server this device cannot read, plus public routing. A failure
+ * to decrypt would cost a tombstone, which is worse than the file being
