a75cbcd224 feat: resource caps, Saved Messages, author walls, docs for node bring-up
Node flags (cmd/node/main.go):
  --max-cpu / --max-ram-mb — Go runtime caps (GOMAXPROCS / GOMEMLIMIT)
  --feed-disk-limit-mb — hard 507 refusal for new post bodies over quota
  --chain-disk-limit-mb — advisory watcher (can't reject blocks without
  breaking consensus; logs WARN every minute)

Client — Saved Messages (self-chat):
  - Auto-created on sign-in, pinned top of chat list, blue bookmark avatar
  - Send short-circuits the relay (no encrypt, no fee, no mailbox hop)
  - Empty state rendered outside inverted FlatList — fixes the mirrored
    "say hi…" on Android RTL-aware layout builds
  - PostCard shows "You" for own posts instead of the self-contact alias

Client — user walls:
  - New route /(app)/feed/author/[pub] with infinite-scroll via
    `created_at` cursor and pull-to-refresh
  - Profile screen gains "View posts" button (universal) next to
    "Open chat" (contact-only)

Feed pipeline:
  - Bump client JPEG quality 0.5 → 0.75 to match server scrubber (Q=75),
    so a 60 KiB compose doesn't balloon past 256 KiB after server re-encode
  - ErrPostTooLarge now wraps with the actual size vs cap, errors.Is
    preserved in the HTTP layer
  - FeedMailbox quota + DiskUsage surface — supports new CLI flag

README:
  - Step-by-step "first node / joiner" section on the landing page,
    full flag tables incl. the new resource-cap group, minimal
    checklists for open/private/low-end deployments

e62b72b5be fix(client): safeBack helper + prevent self-contact-request
1. GO_BACK warning & stuck screens

   When a deep link or direct push put the user on /feed/[id],
   /profile/[address], /compose, or /settings without any prior stack
   entry, tapping the header chevron emitted:
     "ERROR The action 'GO_BACK' was not handled by any navigator"
   and did nothing — user was stuck.

   New helper lib/utils.safeBack(fallback = '/(app)/chats') wraps
   router.canGoBack() — when there's history it pops; otherwise it
   replace-navigates to a sensible fallback (chats list by default,
   '/' for auth screens so we land back at the onboarding).

   Applied to every header chevron and back-from-detail flow:
   app/(app)/chats/[id], app/(app)/compose, app/(app)/feed/[id]
   (header + onDeleted), app/(app)/feed/tag/[tag],
   app/(app)/profile/[address], app/(app)/new-contact (header + OK
   button on request-sent alert), app/(app)/settings,
   app/(auth)/create, app/(auth)/import.

2. Prevent self-contact-request

   new-contact.tsx now compares the resolved address against
   keyFile.pub_key at two points:
     - right after resolveUsername + getIdentity in search() — before
       the profile card even renders, so the user doesn't see the
       "Send request" CTA for themselves.
     - inside sendRequest() as a belt-and-braces guard in case the
       check was somehow bypassed.
   The search path shows an inline error ("That's you. You can't
   send a contact request to yourself."); sendRequest falls back to
   an Alert with the same meaning. Both compare case-insensitively
   against the pubkey hex so mixed-case pastes work.

   Technically the server would still accept a self-request (the
   chain stores it under contact_in:<self>:<self>), but it's a dead-
   end UX-wise — the user can't chat with themselves — so the client
   blocks it preemptively instead of letting users pay the fee for
   nothing.

f7a849ddcb chore(client): translate all user-visible strings to English
Mixed-language UI was confusing — onboarding said "Why DChain / How it
works / Your keys" in English headings but feature descriptions and
CTAs were in Russian; compose's confirm dialog was Russian; feed tabs
were Russian; error messages in humanizeTxError were Russian.
Everything user-facing is now English.

Files touched (only string literals, not comments):
  app/index.tsx              onboarding slides + CTA buttons
  app/(app)/compose.tsx      composer alerts, header button, placeholder,
                             attachment-size hint
  app/(app)/feed/index.tsx   tab labels (Following/For you/Trending),
                             empty-state hints, retry button
  app/(app)/feed/[id].tsx    post detail header + stats rows (Views,
                             Likes, Size, Paid to publish, Hosted on,
                             Hashtags)
  app/(app)/feed/tag/[tag].tsx  empty-state copy
  app/(app)/profile/[address].tsx  Profile header, Follow/Following,
                             Edit, Open chat, Address, Copied, Encryption,
                             Added, Members, unknown-contact hint
  app/(app)/new-contact.tsx  Search title, placeholder, Search button,
                             empty-state hint, E2E-ready indicator,
                             Intro label + placeholder, fee-tier labels
                             (Min / Standard / Priority), Send request,
                             Insufficient-balance alert, Request-sent
                             alert
  app/(app)/requests.tsx     Notifications title, empty-state, Accept /

  components/SearchBar.tsx   default placeholder
  components/feed/PostCard.tsx  long-press menu (Delete post, confirm,
                             Actions / Cancel)
  components/feed/ShareSheet.tsx  sheet title, contact-search placeholder,
                             empty state, Select contacts / Send button,
                             plural helper rewritten for English
  components/chat/PostRefCard.tsx  "POST" ribbon, "photo" indicator
  lib/api.ts                 humanizeTxError (rate-limit, clock skew,
                             bad signature, 400/5xx/network-error
                             messages)
  lib/dates.ts               dateBucket now returns Today/Yesterday/
                             "Jun 17, 2025"; month array switched to
                             English short forms

Code comments left in Russian intentionally — they're developer
context, not user-facing. This commit is purely display-string.

3e9ddc1a43 chore(client): remove dev-seed for chats + feed
Two dev-only seed modules removed now that the app talks to a real
backend:

- lib/devSeed.ts — fake 15+ contacts with mock chat histories,
  mounted via useDevSeed() in (app)/_layout.tsx on empty store.
  Was useful during client-first development; now it fights real
  contact sync and confuses operators bringing up fresh nodes
  ("why do I see NBA scores and a dchain_updates channel in my
  chat list?").

- lib/devSeedFeed.ts — 12 synthetic feed posts surfaced when the
  real API returned empty. Same reasoning: operator imports genesis
  key on a fresh node, opens Feed, sees 12 mock posts that aren't on
  their chain. "Test data" that looks real is worse than an honest
  empty state.

Feed screen now shows its proper empty state ("Пока нет
рекомендаций", etc.) when the API returns zero items OR on network
error. Chat screen starts empty until real contacts + messages
arrive via WS / storage cache.

Also cleaned a stale comment in chats/[id].tsx that referenced
devSeed.

6425b5cffb feat(feed/chat): lazy-render + pagination for long scrolls
Server pagination
  - blockchain.PostsByAuthor signature extended with beforeTs int64;
    passing 0 keeps the previous "everything, newest first" behaviour,
    non-zero skips posts with CreatedAt >= beforeTs so clients can
    paginate older results.
  - node.FeedConfig.PostsByAuthor callback type updated; the two
    /feed endpoints that use it (timeline + author) now accept
    `?before=<unix_seconds>` and forward it through. /feed/author
    limit default dropped from 50 to 30 to match the client's page
    size.
  - node/api_common.go: new queryInt64 helper for parsing the cursor
    param safely (matches the queryInt pattern already used).

Client infinite scroll (Feed tab)
  - lib/feed.ts: fetchTimeline / fetchAuthorPosts accept
    `{limit?, before?}` options. Old signatures still work for other
    callers (fetchForYou / fetchTrending / fetchHashtag) — those are
    ranked feeds that don't have a stable cursor so they stay
    single-shot.
  - feed/index.tsx: tracks loadingMore / exhausted state. onEndReached
    (threshold 0.6) fires loadMore() which fetches the next 20 posts
    using the oldest currently-loaded post's created_at as `before`.
    Deduplicates on post_id before appending. Stops when the server
    returns < PAGE_SIZE items. ListFooterComponent shows a small
    spinner during paginated fetches.
  - FlatList lazy-render tuning on all feed lists (index + hashtag):
    initialNumToRender:10, maxToRenderPerBatch:8, windowSize:7,
    removeClippedSubviews — first paint stays quick even with 100+
    posts loaded.

Chat lazy render
  - chats/[id].tsx FlatList: initialNumToRender:25 (~1.5 screens),
    maxToRenderPerBatch:12, windowSize:10, removeClippedSubviews.
    Keeps initial chat open snappy on conversations with thousands
    of messages; RN re-renders a small window around the viewport
    and drops the rest.

Tests
  - chain_test.go updated for new PostsByAuthor signature.
  - All 7 Go packages green.
  - tsc --noEmit clean.

0bb5780a5d feat(feed/chat): VK-style share post to chats + list breathing room
Feed list padding
  FlatList had no inner padding so the first post bumped against the
  tab strip and the last post against the NavBar. Added paddingTop: 8
  / paddingBottom: 24 on contentContainerStyle in both /feed and
  /feed/tag/[tag] — first card now has a clear top gap, last card
  doesn't get hidden behind the FAB or NavBar.

Share-to-chat flow
  Replaces the placeholder share button (which showed an Alert with
  the post URL) with a real "forward to chats" flow modeled on VK's
  shared-wall-post embed.

  New modules
    lib/forwardPost.ts       — encodePostRef / tryParsePostRef +
                               forwardPostToContacts(). Serialises a
                               feed post into a tiny JSON payload that
                               rides the same encrypted envelope as any
                               chat message; decode side distinguishes
                               "post_ref" payloads from regular text by
                               trying JSON.parse on decrypted text.
                               Mirrors the sent message into the sender's
                               local history so they see "you shared
                               this" in the chat they forwarded to.

    components/feed/ShareSheet.tsx
                             — bottom-sheet picker. Multi-select
                               contacts via tick-box, search by
                               username / alias / address prefix.
                               "Send (N)" dispatches N parallel
                               encrypted envelopes. Contacts with no
                               X25519 key are filtered out (can't
                               encrypt for them).

    components/chat/PostRefCard.tsx
                             — compact embedded-post card for chat
                               bubbles. Ribbon "ПОСТ" label +
                               author + 3-line excerpt + "с фото"
                               indicator. Tap → /(app)/feed/{id} full
                               post detail. Palette switches between
                               blue-bubble-friendly and peer-bubble-
                               friendly depending on bubble side.

  Message pipeline
    lib/types.ts           — Message.postRef optional field added.
                             text stays "" when the message is a
                             post-ref (nothing to render as plain text).
    hooks/useMessages.ts   + hooks/useGlobalInbox.ts
                           — post decryption of every inbound envelope
                             runs through tryParsePostRef; matching
                             messages get the postRef attached instead
                             of the raw JSON in .text.
    components/chat/MessageBubble.tsx
                           — renders PostRefCard inside the bubble when
                             msg.postRef is set. Other bubble features
                             (reply quote, attachment preview, text)
                             still work around it.

  PostCard
    - share icon now opens <ShareSheet>; the full-URL placeholder is
      gone. ShareSheet is embedded at the PostCard level so each card
      owns its own sheet state (avoids modal-stacking issues).

c5ca7a0612 feat(feed): image previews + inline header + 5-line truncation + drop comments
Server
  node/api_feed.go: new GET /feed/post/{id}/attachment route. Returns
  raw attachment bytes with the correct Content-Type so React Native's
  <Image source={uri}> can stream them directly without the client
  fetching + decoding base64 from the main /feed/post/{id} JSON (would
  blow up memory on a 40-post timeline). Respects on-chain soft-delete
  (410 when tombstoned). Cache-Control: public, max-age=3600, immutable
  — attachments are content-addressed so aggressive caching is safe.

PostCard — rewritten header row
  - Avatar + name + time collapsed into a single Pressable row with
    flexDirection:'row'. Name gets flexShrink:1 + numberOfLines:1 so
    long handles truncate with "…" mid-row instead of pushing the time
    onto a second line. Time and separator dot both numberOfLines:1
    with no flex — they never shrink, so "2h" stays readable.
  - Whole header is one tap target → navigates to the author's profile.

PostCard — body truncation
  - Timeline view (compact=false): numberOfLines={5} + ellipsizeMode:
    'tail'. Long posts collapse to 5 lines with "…"; tapping the card
    opens the detail view where the full body is shown.
  - Detail view (compact=true): no line cap — full text, then full-
    size attachment below.

PostCard — real image previews
  - <Image source={{ uri: `${node}/feed/post/${id}/attachment` }}>
    (feed layout).
  - Timeline: aspectRatio: 4/5 + resizeMode:'cover' — portrait photos
    get cropped so one tall image can't eat the whole feed.
  - Detail: aspectRatio: 1 + resizeMode:'contain' so the full image
    fits in its original proportions (crop-free).

PostCard — comments button removed
  v2.0.0 doesn't implement replies; a dead button with label "0" was
  noise. Action row now has 3 cells: heart (with live like count),
  eye (views), share (pinned right). Spacing stays balanced because
  each of the first two cells is still flex:1.

Post detail screen
  - Passes compact prop so the PostCard above renders in full-body /
    full-attachment mode.
  - Dropped the old AttachmentPreview placeholder — PostCard now
    handles images in both modes.

Tests
  - go test ./... — all 7 packages green (blockchain / consensus /
    identity / media / node / relay / vm).
  - tsc --noEmit on client-app — 0 errors.

7bfd8c7dea fix(feed): side padding on action row + stable FAB right-anchor
- Post action row (chat / ❤ / eye / share) had only a small paddingRight
  and no left padding. First icon sat flush under the avatar and share
  iron against the card edge. Replaced with paddingHorizontal: 12 so
  both sides get equal breathing room; each of the four cells still
  flex:1 so the icons distribute evenly.
- FAB kept appearing at the LEFT edge instead of the right on user's
  device despite position:absolute + right:12. Pressable's dynamic-
  function style can drop absolute-positioning fields between renders
  on some RN versions. Wrapping the Pressable in a plain absolute-
  positioned View fixes this: positioning lives on the View (never
  re-evaluated mid-render), the Pressable inside only declares size
  and visuals. pointerEvents="box-none" on the wrapper keeps taps
  outside the button passing through to the feed list below.

f688f45739 fix(feed): breathing room around divider + FAB back to right/bottom corner
- PostSeparator was a bare 1px line flush against both neighbouring
  cards, so the seam looked like card contact instead of a real
  break. Wrapped it in a 12px vertical padding — now there's 12px
  blank above the line, 1px line, 12px blank below. Trimmed the
  card's own paddingVertical back down since the separator now owns
  the inter-post breathing room.
- FAB was lifted to bottom: max(insets.bottom, 8) + 70 in the previous
  commit which put it far too high (a leftover from the original
  experiment with the absoluteFill wrapper). User wants 12px above
  the NavBar and 12px from the right edge. The Feed screen's
  container ends at the NavBar top (enforced by (app)/_layout.tsx's
  outer <View flex:1> + NavBar sibling), so a simple `right: 12,
  bottom: 12` on position:absolute lands the button exactly there on
  every device. Removed the now-unnecessary absoluteFill wrapper too.

a248c540d5 fix(feed): visible post divider + reliable FAB positioning
- Post divider was on each PostCard's outer Pressable as borderBottom
  (#222), which was barely visible on OLED black and disappeared
  entirely in pressed state (the pressed bg ate the line). Moved the
  seam to a dedicated PostSeparator component (1px, #2a2a2a) wired as
  FlatList's ItemSeparatorComponent on both /feed (timeline / for-you
  / trending) and /feed/tag/[tag]. Also bumped inter-card vertical
  padding (14-16 top / 16-20 bottom) so cards have real breathing room
  even before the divider.
- FAB position was flaky: with <Stack> at the (app) level the overlay
  could end up positioned against the Stack's card view instead of the
  tab container, which made the button drift around and stick against
  unexpected edges. Wrapped it in an absoluteFill container with
  pointerEvents="box-none" — the wrapper owns positioning against the
  tab screen, the button inside just declares right: 14 / bottom: N.
  Bumped bottom offset to `max(insets.bottom, 8) + 70` so the FAB
  always clears the 5-icon NavBar with ~14px visual gap on every
  device. Shadow switched from blue-cast to standard dark for better
  depth perception on dark backgrounds.

51bc0a1850 fix(feed): card spacing, action-row distribution, tab strip, detail inset
- PostCard rows got cramped paddings and a near-invisible divider.
  Increased paddingTop 12→16, paddingBottom 12→18, paddingHorizontal
  14→16; divider colour #141414→#222222 so the seam between posts is
  legible on OLED blacks.
- Action row (chat / ❤ / view / share) used a fixed gap:32 + spacer.
  Reworked to four flex:1 cells with justifyContent: space-between,
  so the first three icons distribute evenly across the row and share
  pins to the right edge. Matches Twitter's layout where each action
  occupies a quarter of the row regardless of label width.
- Feed tab strip (Подписки / Для вас / В тренде) used flex:1 +
  gap:10 which bunched the three labels together visually. Switched
  to justifyContent: space-between + paddingHorizontal:20 so each
  tab hugs its label and the three labels spread to the edges with
  full horizontal breathing room.
- Post detail screen (/feed/[id]) and hashtag feed (/feed/tag/[tag])
  were missing the safe-area top inset — their headers butted right
  against the status bar / notch. Added useSafeAreaInsets().top as
  paddingTop on the outer View, matching the rest of the app.

93040a0684 fix(client): DM-only info, seed on API error, proper cross-group back stack
Three related UX fixes on the client.

1. Participants count on profile

   DMs always have exactly two participants (you and the contact) so a
   "Участников: 1" row was confusing — either it's obviously the other
   person or it's wrong depending on how you count. Removed for direct
   conversations; the row still appears for group chats (and shows an
   em-dash until v2.1.0 gives groups a real member list).

2. Dev feed seed now activates on network / 404 errors

   The seed was only surfaced when the real API returned an EMPTY
   array. If the node was down (Network request failed) or the endpoint
   replied 404, the catch block quietly set posts to [] and the list
   stayed blank — defeating the point of the seed. Now both the empty-
   response path AND the network-error path fall back to getDevSeedFeed(),
   so scrolling / like-toggling works even without a running node.

   Also made the __DEV__ lookup more defensive: use `globalThis.__DEV__`
   at runtime instead of the typed global. Some bundler configurations
   have the TS type but not the runtime binding, or vice-versa — the
   runtime lookup always agrees with Metro.

3. Back from profile → previous screen instead of tab root

   Root cause: AnimatedSlot rendered <Slot>, which is stack-less. When
   /chats/xyz pushed /profile/abc (cross-group), the chats group
   unmounted. Hitting Back then re-entered chats at its root (/chats
   list) rather than /chats/xyz.

   Replaced <Slot> with <Stack> in AnimatedSlot. Tab switching still
   stays flat because NavBar uses router.replace (which maps to
   navigation.replace on the Stack — no history accumulation).
   Cross-group pushes (post author tap from feed, avatar tap from chat
   header, compose modal) now live in the outer Stack's history, so
   Back pops correctly to the caller.

   The nested Stacks (chats/_layout.tsx, feed/_layout.tsx,
   profile/_layout.tsx) still handle intra-group navigation as before.
   The PanResponder-based swipe-right-to-back was removed since the
   native Stack now provides iOS edge-swipe natively; Android uses the
   system back button.

   animation: 'none' keeps the visual swap instant — matches the prior
   Slot look so nothing flashes slide-animations that weren't there
   before. Sub-group layouts can opt into slide_from_right themselves
   (profile/_layout.tsx and feed/_layout.tsx already do).

98a0a4b8ba fix(nav): move feed.tsx → feed/index.tsx to unblock duplicate-route error
expo-router error: "A navigator cannot contain multiple 'Screen'
components with the same name (found duplicate screen named 'feed')".

Cause: having both app/(app)/feed.tsx (a file-route) and
app/(app)/feed/ (a folder with _layout.tsx) at the same level makes
expo-router try to register two routes called "feed".

Fix: the folder's _layout.tsx wraps the tab + its sub-routes in a
single Stack, so the tab screen becomes feed/index.tsx — the initial
screen of that Stack. Back navigation from /feed/[id] and
/feed/tag/[tag] now correctly pops to the Feed tab root.

No other route references changed (paths like /(app)/feed,
/(app)/feed/<id>, /(app)/feed/tag/<tag> still resolve identically).

5728cfc85a fix(client): profile polish + proper back stack + dev feed seed
Profile screen
  - Missing safe-area top inset on the header — fixed by wrapping the
    outer View in paddingTop: insets.top (matches the rest of the tab
    screens).
  - "Чат" button icon + text sat on two lines because the button used
    column layout by default. Rewritten as a full-width CTA pill with
    flexDirection: row and alignItems: center → chat-bubble icon and
    label sit on one line.
  - Dedicated "Копировать адрес" button removed. The address row in
    the info card is now the tap target: pressing it copies to clipboard
    and flips the row to "Скопировано" with a green check for 1.8s.
  - Posts tab removed entirely. User's right — a "chat profile" has no
    posts concept, just participant count + date + encryption. The
    profile screen is now a single-view info card (address, encryption
    status, added date, participants). Posts are discoverable via the
    Feed tab; a dedicated /feed/author/{pub} screen is on the roadmap
    for browsing a specific user's timeline.

Back-stack navigation
  - app/(app)/profile/_layout.tsx + app/(app)/feed/_layout.tsx added,
    each with a native <Stack>. The outer AnimatedSlot is stack-less
    (intentional — it animates tab switches), so without these nested
    stacks `router.back()` from a profile screen had no history to pop
    and fell through to root. Now tapping an author in the feed → back
    returns to feed; opening a profile from chat header → back returns
    to the chat.

Dev feed seed
  - lib/devSeedFeed.ts: 12 synthetic posts (text-only, mix of hashtags,
    one with has_attachment, varying likes/views, timestamps from "1m
    ago" to "36h ago"). Exposed via getDevSeedFeed() — stripped from
    production via __DEV__ gate.
  - Feed screen falls back to the dev seed only when the real API
    returned zero posts. Gives something to scroll / tap / like-toggle
    before the backend has real content; real data takes over as soon
    as it arrives.

Note: tapping a mock post into detail will 404 against the real node
(the post_ids don't exist on-chain). Intentional — the seed is for
scroll + interaction feel, not deep linking.

5b64ef2560 feat(client): Twitter-style social feed UI (Phase C of v2.0.0)
Ships the client side of the v2.0.0 feed feature. Folds client-app/
into the monorepo (was previously .gitignored as "tracked separately"
but no separate repo ever existed — for v2.0.0 the client is
first-class).

Feed screens

  app/(app)/feed.tsx — Feed tab
    - Three-way tab strip: Подписки / Для вас / В тренде backed by
      /feed/timeline, /feed/foryou, /feed/trending respectively
    - Default landing tab is "Для вас" — surfaces discovery without
      requiring the user to follow anyone first
    - FlatList with pull-to-refresh + viewability-driven view counter
      bump (posts visible ≥ 60% for ≥ 1s trigger POST /feed/post/…/view)
    - Floating blue compose button → /compose
    - Per-post liked_by_me fetched in batches of 6 after list load

  app/(app)/compose.tsx — post composer modal
    - Fullscreen, Twitter-like header (✕ left, Опубликовать right)
    - Auto-focused multiline TextInput, 4000 char cap
    - Hashtag preview chips that auto-update as you type
    - expo-image-picker + expo-image-manipulator pipeline: resize to
      1080px max-dim, JPEG Q=50 (client-side first-pass compression
      before the mandatory server-side scrub)
    - Live fee estimate + balance guard with a confirmation modal
      ("Опубликовать пост? Цена: 0.00X T · Размер: N KB")
    - Exif: false passed to ImagePicker as an extra privacy layer

  app/(app)/feed/[id].tsx — post detail
    - Full PostCard rendering + detailed info panel (views, likes,
      size, fee, hosting relay, hashtags as tappable chips)
    - Triggers bumpView on mount
    - 410 (on-chain soft-delete) routes back to the feed

  app/(app)/feed/tag/[tag].tsx — hashtag feed

  app/(app)/profile/[address].tsx — rebuilt
    - Twitter-ish profile: avatar, name, address short-form, post count
    - Posts | Инфо tab strip
    - Follow / Unfollow button for non-self profiles (optimistic UI)
    - Edit button on self profile → settings
    - Secondary actions (chat, copy address) when viewing a known contact

Supporting library

  lib/feed.ts — HTTP wrappers + tx builders for every /feed/* endpoint:
    - publishPost (POST /feed/publish, signed)
    - publishAndCommit (publish → on-chain CREATE_POST)
    - fetchPost / fetchStats / bumpView
    - fetchAuthorPosts / fetchTimeline / fetchForYou / fetchTrending /
      fetchHashtag
    - buildCreatePostTx / buildDeletePostTx
    - buildFollowTx / buildUnfollowTx
    - buildLikePostTx / buildUnlikePostTx
    - likePost / unlikePost / followUser / unfollowUser / deletePost
      (high-level helpers that bundle build + submitTx)
    - formatFee, formatRelativeTime, formatCount — Twitter-like display
      helpers

  components/feed/PostCard.tsx — core card component
    - Memoised for performance (N-row re-render on every like elsewhere
      would cost a lot otherwise)
    - Optimistic like toggle with heart-bounce spring animation
    - Hashtag highlighting in body text (tappable → hashtag feed)
    - Long-press context menu (Delete, owner-only)
    - Views / likes / share-link / reply icons in footer row

Navigation cleanup

  - NavBar: removed the SOON pill on the Feed tab (it's shipped now)
  - (app)/_layout: hide NavBar on /compose and /feed/* sub-routes
  - AnimatedSlot: treat /feed/<id>, /feed/tag/<t>, /compose as
    sub-routes so back-swipe-right closes them

Channel removal (client side)

  - lib/types.ts: ContactKind stripped to 'direct' | 'group'; legacy
    'channel' flag removed. `kind` field kept for backward compat with
    existing AsyncStorage records.
  - lib/devSeed.ts: dropped the 5 channel seed contacts.
  - components/ChatTile.tsx: removed channel kindIcon branch.

Dependencies

  - expo-image-manipulator added for client-side image compression.
  - expo-file-system/legacy used for readAsStringAsync (SDK 54 moved
    that API to the legacy sub-path; the new streaming API isn't yet
    stable).

Type check

  - npx tsc --noEmit — clean, 0 errors.

Next (not in this commit)

  - Direct attachment-bytes endpoint on the server so post-detail can
    actually render the image (currently shows placeholder with URL)
  - Cross-relay body fetch via /api/relays + hosting_relay pubkey
  - Mentions (@username) with notifications
  - Full-text search
