88d5cc9f23 Phase 2e: rich comments — optional ref_post_id with signed preview
A comment can now reference a separate Post that carries the full body
(long text, attachments, rich formatting). The inline comment's `content`
becomes a short preview string; the referenced post propagates through the
normal CDN and readers fetch it lazily when rendering the expanded view.

Type change:
- `InlineComment` gains `ref_post_id: Option<PostId>` (#[serde(default)]).
  When None, `content` is the full comment text (v0.6.1 shape — unchanged on
  the wire). When Some, `content` is the preview.

Signature binding:
- `crypto::sign_comment` / `verify_comment_signature` now take
  `ref_post_id: Option<&PostId>`. The signed digest appends
  `b"ref:" || ref_post_id` only when a ref is present, so plain comments
  produce the same digest as the v0.6.1 scheme and remain verifiable
  without a migration. When a ref is present the signature binds it, so a
  peer can't strip or swap the reference without re-signing.

Storage:
- `comments` table gets a `ref_post_id BLOB` column (nullable). Added to
  both the CREATE TABLE statement and a conditional ALTER TABLE migration
  so upgraded DBs pick it up automatically.
- `store_comment`, `get_comments`, `get_comments_with_tombstones` read and
  write the column.

Node API:
- `comment_on_post` stays as the plain-comment entry point (calls the
  inner helper with `ref_post_id = None`).
- New `comment_on_post_with_ref(post_id, preview, ref_post_id)` for rich
  comments. Both share a single inner helper that signs, stores, and
  propagates via BlobHeaderDiff.

connection.rs BlobHeaderDiff handler passes `comment.ref_post_id.as_ref()`
to the signature verify so forged or rewritten refs are rejected.

Tests: new crypto test asserting the signature binds ref_post_id (strip /
swap / drop all fail); new storage test asserting ref_post_id roundtrips
through live + tombstone reads. 116 / 116 core tests pass.

Client-side UX (pulling the ref post on expand, composing rich comments)
is frontend work that will land with the next UI iteration.

8b2881d84a Phase 2d: profile posts signed by the posting identity
Display metadata (display_name, bio, avatar_cid) is no longer broadcast via
the ProfileUpdate direct push when the user edits their name. It travels as
a signed public post with VisibilityIntent::Profile, authored by the posting
identity, and propagates through the normal neighbor-manifest CDN path.

Core pieces:
- `types::ProfilePostContent` — JSON payload serialized into the post's
  content field. Ed25519 signature by the posting secret over length-prefixed
  display_name + bio + 32-byte avatar_cid (or zeros) + timestamp.
- `crypto::{sign,verify}_profile` with strict length prefixing to prevent
  extension attacks.
- New `profile` module: `build_profile_post`, `verify_profile_post`,
  `apply_profile_post_if_applicable`. Last-writer-wins by timestamp.
- `control::receive_post` now verifies Profile-intent posts upfront (same
  as Control) so bogus signatures never enter storage, and applies them
  after store so the `profiles` row updates atomically with the insert.

Node API:
- `Node::set_profile` rewritten: builds a signed Profile post, stores under
  intent=Profile, applies it locally (upserts the profiles row keyed by the
  posting identity), then propagates via `update_neighbor_manifests_as`.
  Stops calling `network.push_profile` — display changes no longer trigger
  a direct wire push.
- `Node::my_profile` / `has_profile` read by `default_posting_id` instead of
  `node_id`, matching where the row is written now.

ProfileUpdate (0x50) and push_profile stay for now — they still carry
routing-only data (anchors, recent_peers, preferred_peers) via
`sanitized_for_network_broadcast` and are used by `set_anchors` /
`set_public_visible`. Removing the routing fields would be a broader
cleanup; scoped out of this phase.

Tests: roundtrip verify+store, wrong-author rejection (not stored), and
older-timestamp ignored. 114 / 114 core tests pass.

eabdb7ba4f Phase 2c: remove audience + PostPush + PostNotification + AudienceRequest/Response
v0.6.2 wire fork: every persona-identifying direct push is gone. Public posts
propagate only through the CDN (pull + header-diff neighbor propagation).
Encrypted posts propagate only through pull with merged author-or-recipient
match. There is no remaining sender→recipient traffic correlation signal on
the wire for content.

Protocol (network-breaking):
- Retire MessageType 0x42 (PostNotification), 0x43 (PostPush),
  0x44 (AudienceRequest), 0x45 (AudienceResponse). Their payload structs are
  deleted along with the handlers and senders.
- SocialDisconnectNotice (0x71) / SocialAddressUpdate (0x70) sender
  functions targeting audience are deleted; the existing handlers stay
  (both already dead code on the send side).

Core removals:
- `push_to_audience`, `notify_post`, `push_delete`,
  `push_disconnect_to_audience`, `push_address_update_to_audience`,
  `send_audience_request`, `send_audience_response`, `send_to_audience` —
  all gone from network.rs.
- `handle_post_notification` removed from connection.rs.
- `request_audience`, `approve_audience`, `deny_audience`,
  `remove_audience`, `list_audience_members`, `list_audience` removed from
  Node.
- `audience_pushed` step removed from post creation.
- `AudienceDirection`, `AudienceStatus`, `AudienceRecord`,
  `AudienceApprovalMode` removed from types.
- Storage: `store_audience`, `list_audience`, `list_audience_members`,
  `remove_audience`, `row_to_audience_record`, `audience_crud` test, the
  `audience` CREATE TABLE, and the audience-dependent social route rebuild
  branch all removed. Upgraded DBs retain the orphan `audience` table;
  nothing touches it.

Follow-on cleanups:
- `SocialRelation::Audience` + `::Mutual` collapsed into just `Follow`.
  The Display/FromStr impl accepts legacy "audience"/"mutual" strings from
  pre-v0.6.2 DBs and maps them to Follow.
- Blob-eviction priority function drops the audience factor; relationship
  is now own-author vs followed vs other. Tests updated accordingly.
- `CommentPermission::AudienceOnly` → `FollowersOnly`. Check uses the
  author's public follows (`list_public_follows`) rather than a separate
  audience table. `ModerationMode::AudienceOnly` similarly renamed.
- Follow/unfollow routines simplified: no audience downgrade logic;
  unfollow removes the social route entirely.

UI:
- CLI: `audience*` commands removed.
- Tauri: `AudienceDto`, `list_audience`, `list_audience_outbound`,
  `request_audience`, `approve_audience`, `remove_audience` commands
  removed from invoke_handler. Frontend: audience panel and audience/mutual
  badges removed; compose permission dropdown shows "Followers" instead of
  "Audience"; `loadAudience` is a no-op stub that hides any leftover DOM.

Tests: 111 / 111 core tests pass.

Breaking change: v0.6.2 nodes won't interoperate with v0.6.1 for delete
propagation, visibility updates, direct post push, post notifications, or
audience requests. Upgrade both ends.

36b6a466d2 Phase 2b: control-post flow (delete/visibility) + remove BlobDeleteNotice
Replaces two persona-signed direct pushes with CDN-propagated control posts:
a single `VisibilityIntent::Control` post type whose content is a signed
`ControlOp` the receiver verifies and applies. Deletes and visibility updates
now flow through the same neighbor-manifest CDN path as regular content — no
direct recipient push needed for persona-signed ops.

Core pieces:
- `VisibilityIntent::Control` + `VisibilityIntent::Profile` variants.
- `ControlOp::DeletePost` / `ControlOp::UpdateVisibility` (JSON, ed25519-signed
  by the target post's author over op-specific byte strings).
- `crypto::{sign,verify}_control_{delete,visibility}` signing primitives.
- `control::build_delete_control_post` + `build_visibility_control_post`
  for authors to construct control posts.
- `control::receive_post` — unified incoming-post path used by all 6 receive
  sites. Verifies control signatures BEFORE storing, so bogus controls never
  enter storage and can't be re-propagated via neighbor-manifest diffs.
- `control::apply_control_post_if_applicable` — executes the op under the
  same storage guard as the insert.

Feed filter:
- Feeds (`get_feed`, `get_feed_page`, `list_posts_page`,
  `list_posts_reverse_chron`) now exclude `Control` and `Profile` posts so
  they propagate + tombstone without surfacing.
- Sync/export path (`list_posts_with_visibility`) keeps its own unfiltered
  query so control posts still propagate via CDN.

Wire protocol:
- `SyncPost` carries `intent: Option<VisibilityIntent>` so control posts
  arrive with their intent preserved.
- `BlobDeleteNotice` (0x95) removed — orphan blobs on remote holders evict
  naturally via LRU rather than via a persona-signed push. Code path,
  payload, sender, tests, and `delete_blob_with_cdn_notify` all gone.

Tests: control delete roundtrip (apply + tombstone) and wrong-author
rejection (not stored, not applied). 112/112 core tests pass.

4a1db1ce7f Core: network/posting key split + decrypt-all-personas
Fresh installs now generate two independent ed25519 keys — one as the
network (QUIC) identity in identity.key, and a SEPARATE one as the
default posting identity in posting_identities. They share nothing.

v0.6.0 upgraders: if the default posting key equals the network key
(the state Phase 4's migration left us in), rotate identity.key to a
fresh random value. The old key stays in posting_identities as the
default persona — peers keep seeing the same author on our posts; only
the QUIC NodeId changes. A one-shot reconnect-churn on upgrade, then
back to normal.

Storage:
- Drop seed_posting_identity_from_network (v0.6.0-specific helper)
- Add count_posting_identities()

Node::open_with_bind:
- Load identity.key (network secret — network-only from now on)
- Ensure posting_identities has at least one entry; if empty, generate
  an INDEPENDENT random posting key as the default
- Detect default-posting-key == network-key collision and rotate
  identity.key, logging the migration
- default_posting_id / default_posting_secret resolved from storage

Decrypt:
- decrypt_posts now takes &[PostingIdentity] and tries each held
  persona as a recipient candidate. Past DMs to any persona on this
  device (including ones added via Import as personas) decrypt
  correctly. Callers pre-load list_posting_identities() alongside
  group_seeds.
- decrypt_just_created looks up the author's specific posting identity
  rather than assuming the default.

Profile broadcasts (wire-level privacy):
- Profile stays keyed by network NodeId — the field is load-bearing
  for N1/N2/N3 social routing (anchors/recent_peers/preferred_peers
  feed build_preferred_tree_for and peer-anchor reachability lookup).
- But push_profile and InitialExchange now STRIP display_name, bio,
  and avatar_cid before sending, via new
  PublicProfile::sanitized_for_network_broadcast(). A name attached to
  the network id would correlate the QUIC endpoint to a human. Until
  v0.6.2 introduces persona-signed profile posts, peers display
  authors as hex.

Auto-follow only the default posting id (network id is never an
author, following it would be dead weight).

All 111 core tests pass.

7bdb2eb736 Phase 5 (0.6.4-beta) backend: multi-persona creation + post-as
Users can now hold multiple posting identities on one device and
publish content under any of them. Each persona has its own ed25519
key; peers see them as distinct authors with no link back to the
device's network identity.

Node methods:
- list_posting_identities() -> Vec<PostingIdentity>
- create_posting_identity(display_name) — generates a fresh ed25519
  key, persists, auto-follows self
- delete_posting_identity(node_id) — refuses to delete the default
- set_default_posting_identity(node_id) — validates identity exists;
  Node's cached default_posting_id/secret picks up on next restart
- create_post_as(posting_id, content, intent, attachments) — routes
  through a shared create_post_inner that takes posting_id +
  posting_secret as parameters

Post creation pipeline:
- create_post_with_visibility now delegates to create_post_inner
  using default_posting_id/secret
- create_post_inner threads posting_id / posting_secret through
  every content-signing, encryption, manifest, blob-header, and
  CDN-manifest step — the persona is fully honored end to end
- update_neighbor_manifests now takes a posting_id param too, so
  posts from persona X only update neighbor manifests for X's own
  prior posts

Tauri IPC:
- list_posting_identities / create_posting_identity /
  delete_posting_identity / set_default_posting_identity
- create_post_as with posting_id_hex + the same visibility params
  as create_post

CLI:
- personas / create-persona <name> / delete-persona <id>
- post-as <posting_id> <text>

Smoke-tested two-persona scenario:
- A creates "Work" persona; posts from default and Work
- B follows both; pulls from A; gets all three posts
- Authors are AB84BA... (Work) and 7CD949... (default) — distinct
  on the wire

Frontend UX (Settings > Personas, compose picker, filter pills,
merged feed labels) is scoped as a separate commit.

ce4b989b17 Phase 4 (0.6.3-beta): posting-key / network-key split (plumbing)
Decouple the signing identity from the network identity. This phase
ships the plumbing only — every device still has exactly one posting
identity, copied from the network key on first 0.6.3 launch so all
existing signed content keeps verifying. Phase 5 builds the
multi-persona UX on top.

Types:
- New PostingIdentity struct: { node_id, secret_seed, display_name,
  created_at }

Storage:
- New posting_identities(node_id, secret_seed, display_name,
  created_at) table
- Methods: upsert / get / list / delete posting identities;
  get/set default posting id (stored in settings)
- seed_posting_identity_from_network: idempotent migration inserts
  the network key as the single posting identity and sets it default
  on first 0.6.3 launch

Node:
- default_posting_id + default_posting_secret fields populated on
  startup via the migration
- All content signing / encryption / key wrapping now uses
  default_posting_secret; the old Node.secret_seed field is gone
  (iroh holds the network secret internally)
- author field on all locally-created content is now
  default_posting_id (equal to node_id for upgraders until Phase 5
  introduces separate personas)
- Auto-follow-self covers both network_id and default_posting_id
  (same in 0.6.3, may diverge in 0.6.4+)

Export/import:
- Bundle now includes posting_identities.json in
  IdentityOnly / PostsWithIdentity / Everything scopes
- restore_posting_identities(zip, storage) reads and upserts on
  import

Smoke-tested:
- Fresh 0.6.3 install: posting_identities seeded from network key;
  default set; new post's author = default_posting_id = network_id
- Two-node pull sync: B pulls A's post, signature verifies across
  the wire
- 111 core tests pass

5d9ba22427 Phase 2e (0.6.1-beta): drop legacy upstream/downstream tables
The file_holders table is now the only tracker of per-file peer
relationships. post_upstream, post_downstream, blob_upstream, and
blob_downstream are dropped at first launch after the seed migration
copies any existing entries.

Schema:
- DROP TABLE IF EXISTS on all four legacy tables after seeding
- Seed migration guards with sqlite_master table_exists check so fresh
  installs don't crash trying to read non-existent sources
- Remove CREATE TABLE statements for the four tables from init
- Remove Protocol v4 Phase 6 post_upstream priority migration (dead)
- Remove blob_upstream preferred_tree column migration (dead)

Rust:
- Remove add/get/remove post_upstream, post_downstream,
  blob_upstream, blob_downstream methods
- Remove get_blob_upstream_preferred_tree / update variant
- Rewrite get_eviction_candidates's downstream_count subquery to
  count file_holders entries
- Rewrite apply_delete's cascade cleanup to clear file_holders
  instead of post_upstream/post_downstream
- cleanup_cdn_for_blob now clears file_holders for the CID

Callers:
- All dual-write sites in connection.rs and node.rs now do
  touch_file_holder only (legacy writes removed)
- get_stale_manifests replaced with get_stale_manifest_cids; caller
  in node.rs picks a refresh source from file_holders

Tests:
- Remove blob_upstream_crud, blob_downstream_crud_and_limit,
  blob_upstream_preferred_tree, remove_blob_upstream,
  post_downstream_crud
- Add file_holders_lru_cap and file_holders_direction_promotion tests

All 110 core tests passing. Workspace compiles clean.

60463d1817 Phase 2d (0.6.1-beta): route manifest + blob ops through file_holders
Switch ALL propagation-decision reads to the flat holder set.

push_manifest_to_downstream now targets file_holders instead of
blob_downstream. ManifestPush receive-side relay likewise — known
holders fan out to up to 5 most-recent peers instead of a directional
tree.

Blob delete notices: single flat fan-out to file_holders; the legacy
upstream_node tree-healing field is emitted as None (wire-stable via
serde default) and ignored on receive — the post-0.6 flat model
doesn't need sender-role distinction. send_blob_delete_notices keeps
its Option<&Upstream> parameter as an unused placeholder for signature
stability with the call sites in this commit.

Other reads migrated:
- blob fetch cascade: step 2 now tries "known holders" (up to 5)
  instead of a single upstream
- manifest refresh: downstream_count reported from file_holder_count
- web/http post holder enumeration
- Worm search post/blob holder fallback (both connection.rs paths)
- DeleteRecord fan-out rewires to file_holders
- Under-replication replication check: < 2 holders

Storage additions:
- get_file_holder_count(file_id)
- remove_file_holder(file_id, peer_id)

Legacy upstream/downstream writes are still happening from Phase 2b;
those + the tables themselves go in 2e.

3a0d2e93ab Phase 2c (0.6.1-beta): route engagement diffs through file_holders
propagate_engagement_diff now targets the post's flat holder set (up to
5 most-recent) instead of the post_downstream directional tree. The
holder set naturally subsumes the old upstream+downstream partition, so
the separate "also send to upstreams" loops at each engagement call
site are removed (reactions, comments, comment edit/delete, receipt
slots, comment slots).

handle_blob_header_diff on receive:
- records the sending peer as a file holder (an engagement exchange is
  proof the peer holds the post)
- re-propagates to the holder set minus the sender

Writes to post_upstream / post_downstream still occur from Phase 2b
(dual-write); those and the legacy tables will be removed in 2e.

0b2b4f5a68 Phase 2b (0.6.1-beta): dual-write file_holders on all propagation events
Populate the flat holder set alongside every existing post_upstream /
post_downstream / blob_upstream / blob_downstream write so that read
paths can be switched over in the next commit without losing continuity.

Events wired:
- Pull sync receive (3 paths in connection.rs)
- PostPush receive (public posts only after Phase 1)
- PostFetch via notification (discovery pull)
- PostDownstreamRegister
- Replication accept (downstream) + replication-driven pull (upstream)
- Attachment upstream recorded after replication blob fetch
- ManifestPush receive (remote is a CID holder)
- ManifestPush send (downstream peer becomes CID holder)
- Blob fetch fallback (upstream lateral sources)

Direction is tracked as Received vs Sent. Not load-bearing for routing;
retained for future use. LRU cap of 5 enforced on every touch.

Legacy upstream/downstream writes remain in place; they'll go away
together with the table drops at the end of this phase.

e6265b52b6 Phase 1 (0.6.0-beta): remove direct PostPush for encrypted posts
Encrypted posts now propagate only via the CDN (ManifestPush + neighbor
header updates), eliminating the sender→recipient traffic signal on the
wire. Encrypted DMs are indistinguishable from any other encrypted post.

- Remove push_post_to_recipients entirely from network.rs
- Remove call sites in create_post and re-encrypt-on-revoke
- PostPush handler now ignores non-public visibility (kept for public
  audience push path)

Known gap: non-follower DMs won't reach until Phase 3 (merged pull +
recipient-match). Followers receive via the existing CDN path — new
posts trigger neighbor-manifest updates, ManifestPush fans out to
downstream holders, recipients pull missing post IDs from followed
authors.

288b53ffb1 Feed pagination, duplicate identity detection, pkarr leak fix, Android SAF
Feed pagination:
- Cursor-based pagination: get_feed_page/get_all_posts_page (20 posts/page)
- Batched engagement queries (3 bulk SQL queries instead of 4 per post)
- IntersectionObserver for infinite scroll (sentinel at midpoint)
- Viewport-based media loading (blobs only load when post enters view)
- Pre-fetch next page immediately after current page renders

Duplicate identity detection:
- Anchor detects when a NodeId is already mesh-connected during initial
  exchange and sets duplicate_active flag in response
- Client skips sync tasks when duplicate detected
- Frontend shows red warning banner

Privacy:
- Fixed pkarr leak: clear_address_lookup() removes default dns.iroh.link
  publishing. Only mDNS (local network) discovery enabled.

Android:
- SAF integration via tauri-plugin-android-fs: exports open native "Save As"
  dialog so users can save to Downloads/Drive/etc.
- Download/export paths use app data dir on Android (writable)
- File picker gated behind desktop cfg (blocking_pick not on Android)

1030dc21a7 Sync fixes, hole punch address family filtering, ManifestPush blob fetch
Per-peer sync (People tab Sync button) now resets last_sync_ms to 0 so
the responder sends ALL posts, not just posts newer than last sync.

ManifestPush post discovery now fetches blobs alongside discovered posts
while the connection is live, instead of waiting for the next prefetch cycle.

Hole punch: filter_reachable_families() checks endpoint bound sockets and
removes addresses the local endpoint can't reach (IPv4-only won't try IPv6).
Applied to hole_punch_single, hole_punch_parallel, hole_punch_with_scanning.

Relay introduce paths switched from is_publicly_routable to is_shareable_addr
so LAN addresses (192.168.x.x) are included for same-WiFi hole punching.
is_shareable_addr made pub(crate).

43adbbdf7d v0.4.3: Lock contention overhaul, StoragePool, mobile bottom nav, text scaling
Eliminate all conn_mgr lock holds during network I/O across 14 actor commands
and bi-stream handlers. PostFetch, TcpPunch, PullFromPeer, FetchEngagement,
ResolveAddress, AnchorProbe use brief locks for data gathering only. WormLookup,
ContentSearch, WormQuery use connection snapshots for lock-free cascade fan-out.
RelayIntroduce extracts forwarding data under brief lock, does I/O outside.
BlobRequest, PostFetchRequest, ManifestRefresh use Arc clones instead of conn_mgr
lock. ConnectionActor hoists shared Arcs (storage, blob_store, endpoint) for
lock-free access. ResolveAddress adds 5s per-query timeout (was unbounded).

Initial exchange failure now aborts mesh upgrade (was silently continuing with
broken connection). connect_to_peer/connect_to_anchor use consistent 15s timeout.
Rebalance connects outside the lock via pending_connects pattern.

StoragePool: 8 concurrent SQLite connections in WAL mode replace single
Mutex<Storage>. Reads run fully parallel; writes serialize at SQLite level only.
PRAGMA busy_timeout=5000 for graceful write contention.

Mobile bottom nav bar (<=768px) with icon tabs. Text sizes: XS/S/M/L/XL
(75%/100%/125%/150%/200%), default M. localStorage persistence for instant
restore. Toast repositioned above mobile nav.

bb6f2b64b0 v0.4.1: Security hardening, lock contention fixes, data cleanup
Security:
- Reaction signatures: ed25519 sign/verify (sign_reaction, verify_reaction_signature)
  Backward-compatible — unsigned reactions from old nodes still accepted
- Comment signature verification: verify_comment_signature now called on receipt
- Reaction removal authorization: only reactor or post author can remove
- BlobHeader author verification: lookup actual author from storage, don't trust payload

Lock contention (4 fixes):
- ManifestPush discovery: cm lock released before PostFetch I/O
- Pull request handler: load under lock, filter without lock, brief re-lock for is_deleted
- Pull sender: split into two brief locks (store posts, then batch upstream+sync)
- Engagement checker: batch all chunk results, single lock for writes

Data cleanup:
- Post deletion cleans post_downstream, post_upstream, seen_engagement tables
- Added TODO-hardening.md documenting remaining DOS/security/lock/data issues

bbaacf9b6c v0.4.0: Protocol v4 — header-driven sync, tiered engagement, multi-upstream
Protocol v4 sync overhaul:
- Slim PullSyncRequest: per-author timestamps (since_ms) replace full post ID lists
  Request size O(follows) instead of O(posts). Backward-compatible via serde default.
- Tiered pull frequency: 60s ticks, only syncs stale authors (4hr default)
  Full pull only on first tick (bootstrap). Most ticks skip — no stale authors.
- Tiered engagement checks: frequency scales with content age
  5min (<72h), 1hr (3-14d), 4hr (14-30d), 24hr (>30d)
  Single SQL query filters posts due for check.
- Header-driven post discovery: ManifestPush triggers PostFetch for missing
  followed-author posts (capped 10 per manifest). CDN tree = notification system.
- Multi-upstream (3 max): composite PK, priority ordering, engagement diffs
  sent to all upstreams, promote/remove on failure.

DB schema:
- follows.last_sync_ms — Self Last Encounter per author
- posts.last_engagement_ms — last reaction/comment timestamp
- posts.last_check_ms — last engagement check timestamp
- post_upstream: single-row → 3-row with priority column

Lock contention fixes:
- get_blob_for_post: 3 locks → 1
- prefetch_blobs_from_peer: lock-free blob checks
- fetch_engagement_from_peer: explicit lock release before I/O
- serve_post: 4 locks → 2 (eliminated redundant queries)
- run_replication_check: 2 locks → 1
- Badge cycle: N+2 IPC calls → 1 (get_badge_counts)

89d6a853f5 Fix storage lock contention: reduce lock holds across 6 hot paths
- get_blob_for_post: 3 sequential locks → 1 combined acquisition
- prefetch_blobs_from_peer: lock only for DB reads, blob checks outside lock
- fetch_engagement_from_peer: explicit lock release before next network I/O
- serve_post: 4 locks (2 redundant) → 2
- run_replication_check: 2 locks → 1 combined
- Badge cycle: N+2 IPC calls → 1 (new get_badge_counts command)
- Follow timeout: 15s cap on auto-sync-on-follow to prevent UI hang
- Notification clearing: clear system notifications on conversation read

a7e632de88 v0.3.6: Active CDN replication, device roles, budgets, tombstones, engagement fix, DOS hardening
Active CDN replication:
- All devices proactively replicate recent posts (<72h, <2 replicas) to peers
- Target priority: desktops (300) > anchors (200) > phones (100) + cache_pressure
- ReplicationRequest/Response (0xE1/0xE2) wire messages
- 10-min cycle, 2-min initial delay, cap 20 posts per request
- Graceful with small networks (1 peer = 1 replica, 0 peers = silent skip)

Device roles & budgets:
- Intermittent (phone), Available (desktop), Persistent (anchor)
- Advertised in InitialExchange, stored per-peer
- Replication budget: phones 100MB/hr, desktops/anchors 200MB/hr
- Delivery budget: phones 1GB/hr, desktops 2GB/hr, anchors 1GB/hr
- Hourly auto-reset, enforcement on blob serving

Cache management:
- 1GB default cache limit, configurable in settings UI
- Eviction cycle activated (was implemented but never started)
- Share-link priority boost (+100 for 3+ downstream)
- Cache pressure score (0-255) for replication targeting

Engagement distribution fix:
- BlobHeader JSON rebuilt after BlobHeaderDiff ops
- Previously reactions/comments stored in tables but header stayed stale

Tombstone system:
- deleted_at column on reactions and comments
- Tombstones propagate through pull sync (additive merge respects timestamps)
- UI queries filter WHERE deleted_at IS NULL

Persistent notifications:
- seen_engagement and seen_messages tables replace in-memory Sets
- Only notify on genuinely unseen content, survives restarts

DOS hardening:
- BlobHeaderDiff fan-out: single batched task, max 10 concurrent via JoinSet
- Blob prefetch: cap 20 per cycle, newest first
- PostDownstreamRegister: cap 50 per sync
- Delivery budget enforcement on BlobRequest handler
- Pull preference: non-anchors first to preserve anchor delivery budget

b7f2d369fa v0.3.5: Encrypted receipt & comment slots, message delivery indicators
Encrypted slots in BlobHeader:
- Private posts get noise-prefilled receipt slots (64B, 1 per participant)
  and comment slots (256B, ceil(participants/3), expandable)
- Slot key derived from post CEK via BLAKE3 — only participants can read
- CDN relays propagate opaque encrypted bytes without decryption
- 3 new BlobHeaderDiffOps: WriteReceiptSlot, WriteCommentSlot, AddCommentSlots

Receipt system:
- States: empty(0), delivered(1), seen(2), reacted(3)
- Slot index = position in sorted participant NodeId list
- Author can pre-feed emoji reaction at creation time
- 6 new crypto tests for slot encrypt/decrypt/derivation

Node methods:
- write_receipt_slot, write_comment_slot with upstream+downstream propagation
- read_receipt_slots, read_comment_slots with CEK-based decryption
- get_post_cek_and_participants helper for both Encrypted and GroupEncrypted

IPC: write_message_receipt, write_message_comment, get_message_receipts,
     get_message_comments

Frontend:
- DM chat bubbles show delivery indicators (check → double → blue → emoji)
- Opening conversation auto-marks incoming messages as seen
- React button on messages with emoji prompt

a41b11c0b8 v0.3.5: Private blob encryption, blob prefetch, intent-based filtering, crypto refactoring
Private blob encryption:
- Encrypted posts (Friends/Circle/Direct) now encrypt attachment blobs with same CEK
- Public blobs unchanged, CID computed on ciphertext for private
- decrypt_blob_for_post/get_blob_for_post for transparent decryption on retrieval

Blob prefetch:
- Pull cycle and sync_with eagerly fetch missing blobs after post sync
- prefetch_blobs_from_peer scans for missing attachments, fetches via fallback chain
- Runs outside conn_mgr lock at Node level

Crypto refactoring:
- Extracted: encrypt/decrypt_bytes_with_cek, wrap/unwrap_cek_for_recipients
- unwrap_cek_for_recipient, unwrap_group_cek, random_cek
- encrypt_post_with_cek, encrypt_post_for_group_with_cek variants
- All existing functions refactored to delegate, 19 crypto tests pass

Intent-based filtering:
- intent_kind field on PostDto ("public"/"friends"/"circle"/"direct"/"unknown")
- Feed/MyPosts filter on intentKind !== 'direct' instead of visibility
- Messages filter with backward-compatible fallback for pre-intent posts
- get_post_intent storage method

IPC updates:
- resolve_blob_data helper using get_blob_for_post with network fallback
- sanitize_download_filename prevents path traversal
- get_blob_path accepts optional post_id_hex

Website:
- Mobile hamburger nav on all pages
- Mesh/Non-mesh N1 labels in network diagnostics

0abc244ee9 v0.3.4: Comment edit/delete, native notifications, forward-compatible protocol, UI fixes
Comment edit & delete:
- EditComment/DeleteComment BlobHeaderDiffOps with upstream+downstream propagation
- Trust-based: comment author can edit/delete, post author can delete
- Storage: edit_comment(), delete_comment() methods
- Frontend: inline edit (Enter/Escape), delete with confirm

Native notifications:
- tauri-plugin-notification for system notifications on all platforms
- Triggers for messages, new posts, reactions, and comments
- notif_reacts setting added, button-group toggles replace dropdowns
- _notifReady flag prevents startup spam

Protocol hardening:
- BlobHeaderDiffOp::Unknown variant with #[serde(other)] for forward compatibility
- Old nodes silently skip unknown ops instead of crashing

UI fixes:
- Self removed from Following list
- Offline follows in lightbox popup (auto-show if no one online)
- Sent DMs filtered from My Posts
- Comment threading scoped to closest .post (fixes duplicate ID issue)
- Select dropdown text legible in WebKitGTK (black on white options)
