Removes the last persona-signed direct push on the wire. Group/circle
seeds no longer travel via the 0xA0 `GroupKeyDistribute` uni-stream from
admin to member. Instead the admin publishes an encrypted post containing
the seed + metadata; each member is a recipient; the post propagates via
the normal CDN. Members decrypt with their posting secret to recover the
seed.
Eliminates the wire-level coordination signal between an admin endpoint
and each member endpoint when a group is created, a member is added, or
a key is rotated.
Core pieces:
- New `VisibilityIntent::GroupKeyDistribute` variant.
- New `types::GroupKeyDistributionContent` — JSON payload inside the
encrypted post: group_id, circle_name, epoch, group_public_key, admin,
canonical_root_post_id, group_seed.
- New `group_key_distribution` module:
- `build_distribution_post(admin, admin_secret, record, group_seed, members)`
returns `(PostId, Post, PostVisibility::Encrypted)` — wraps the CEK
per member using standard `crypto::encrypt_post`.
- `try_apply_distribution_post(s, post, visibility, our_personas)`
iterates every posting identity's secret trying to decrypt; on
success stores `group_key` + `group_seed` and returns true.
- `process_pending(s, our_personas)` scans stored
GroupKeyDistribute-intent posts and applies any we can decrypt.
Node API:
- `add_to_circle`: builds a distribution post wrapping the current seed
to just the new member, stores with intent=GroupKeyDistribute, and
propagates via `update_neighbor_manifests_as` (no direct push).
- `create_group_key_inner`: at group creation, after wrapping keys for
every non-self member, builds one distribution post addressed to all
of them and propagates through the CDN.
- `rotate_group_key`: same pattern at epoch rotation.
- New `Node::process_group_key_distributions` — scans and applies.
`sync_all` now calls it automatically so seeds take effect right after
a pull cycle.
Removals (wire-breaking; v0.6.2 already forked):
- MessageType 0xA0 (`GroupKeyDistribute`), its payload struct, the
handler in connection.rs, and `Network::push_group_key` all deleted.
ConnectionManager's `secret_seed` (network secret) is no longer used for
group-key unwrapping — that shifted to posting secrets in the apply
pass, matching the v0.6.1+ identity split where group keys are wrapped
to posting NodeIds.
Tests: new `member_decrypts_and_applies` covers a recipient decrypting +
storing the seed and a non-recipient failing to apply. Workspace
compiles clean; 118 / 118 core tests pass on a stable run (pre-existing
flaky `relay_cooldown` test with a 1ms timing window is unrelated).
Introduces **groups** — a new many-way primitive anchored at a public root
post — reusing the existing circle encryption machinery. Circles stay
one-way (admin posts only, as before). Groups are distinguished from
circles by a single field: a non-null `canonical_root_post_id` on the
group-key record.
Type / schema changes:
- `GroupKeyRecord.canonical_root_post_id: Option<PostId>` (serde default).
When `Some`, the record represents a group rooted at that public post;
when `None`, it's a traditional circle.
- `group_keys` table gets a `canonical_root_post_id BLOB` column + an
index `idx_group_keys_root` on it. Migration added for upgraded DBs;
the CREATE TABLE statement carries the column so fresh DBs match.
Wire:
- `GroupKeyDistributePayload` gains an optional `canonical_root_post_id`
field. v0.6.1 peers will deserialize it as absent and continue treating
the record as a circle. All three sender sites (new-circle distribute,
add-member distribute, epoch-rotation distribute) pass the field through.
Storage:
- `create_group_key` / `get_group_key` / `get_group_key_by_circle` write
and read the new column. Added a shared `row_to_group_key` helper so the
two lookup functions don't drift.
- New `get_group_by_canonical_root(root_post_id)` — the inverse lookup
used by posting / retrieval flows.
Node API (new):
- `create_group_from_post(root_post_id, initial_members)` — creates a
backing circle named `group:<6-byte-hex-of-root>`, initializes the
group key with `canonical_root_post_id` set, and invites each initial
member (reusing `add_to_circle`'s wrap+distribute path so members get
the seed on the wire). Returns `(GroupId, circle_name)`.
- `post_to_group(root_post_id, content, attachments)` — any member with
the group seed can call this. Looks up the group by root, routes
through `create_post_with_visibility(Circle(name))` (which already
chooses `GroupEncrypted` when the seed is present), then stores a
`ThreadMeta` row linking the new post back to the canonical root so
retrieval can reconstruct the group.
- `list_group_posts_by_root(root_post_id)` — returns all contributions
via the ThreadMeta parent index. Callers decrypt normally; members see
full content, non-members see encrypted blobs.
Shared plumbing:
- `create_group_key_for_circle` now delegates to a shared
`create_group_key_inner(circle_name, canonical_root)` helper, keeping
one place where the record is constructed and the seed is persisted.
Notes:
- No crypto change: groups use the same `GroupEncrypted` primitive
circles already used. The "admin-only post" restriction on circles was
a UX choice, not a cryptographic limit — groups expose the many-way
path directly by letting any member with the seed call `post_to_group`.
- ThreadMeta is the clustering primitive. It already existed for split
comment threads; groups reuse it so the query pattern
("posts whose parent is root X") stays in one place.
- Frontend UI for groups is deferred — the backend surface is complete
and exercise-able via Tauri/CLI.
Tests: new storage test asserts canonical_root lookup round-trips and
that circles (no root) are invisible to the root lookup. 117 / 117 core
tests pass.
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.
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.
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)

- Network Diagnostics: "Our Info" button shows addresses with NAT status,
device role, UPnP, HTTP capability. Addresses stacked for mobile.
- Hole punch race: re-check for existing connection before and after relay
introduction to avoid wasting minutes on redundant punch attempts.
- Relay introduction now carries requester/target NAT mapping+filtering
so hole punch strategy uses fresh profiles instead of stale stored ones.
Critical for phones that switch between WiFi/cellular/VPN.
- STUN fix: filter DNS results to IPv4 (was resolving to IPv6 first on
dual-stack, causing silent send failure and "NAT unknown").
- Welcome screen: Ready button with loading bar for instant feed access.
- LAN addresses show just "LAN" (no misleading punchability label).

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.
