Two pre-release fixes found during audit.
1) GroupKeyDistribute admin forgery (critical)
`group_key_distribution::try_apply_distribution_post` trusted the
`admin` field inside the decrypted payload without verifying it
matched the post's author. Exploit: any peer who learns a victim's
posting NodeId (public — appears as a recipient on any DM/group
post) and observes a target group_id in the wild could craft an
encrypted distribution post claiming to be from the legitimate
admin. The victim's storage uses INSERT OR REPLACE on group_keys,
so a successful forgery would overwrite the victim's legitimate
group key record and stored seed, breaking future rotations / key
distributions from the real admin.
Fix: reject the distribution post when `content.admin != post.author`.
Added test `forged_admin_is_rejected` that seeds a legitimate
record, attempts a forgery, and asserts the legitimate record is
untouched.
2) Cap concurrent port-scan hole punches at 1 (bandwidth)
`hole_punch_with_scanning` fires ~100 QUIC ClientHellos/sec for up
to SCAN_MAX_DURATION_SECS (300s), ~1 Mbps per active scanner. With
no cap, the growth loop / anchor referrals / replication paths
could spawn several scanners at once and drive sustained multi-Mbps
upload — particularly pathological on obfuscated VPNs where every
probe stalls at a proxy timeout, explaining the reported 10 Mbps
sustained upload after anchor connect.
Fix: module-level `tokio::sync::Semaphore(1)` guarding entry to the
scanning loop. Second-and-beyond callers fall back to the cheaper
`hole_punch_parallel` (standard punching, no 100/sec port walk)
instead of spawning another scanner. Permit is held for the scanner
lifetime and released on return. Added unit test
`scanner_semaphore_caps_concurrent_scans_at_one`.
Both changes leave the successful-call path untouched (single scanner
still runs; legitimate key distributions still apply). 120 / 120 core
tests pass.
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.
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.
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.
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.
Phase 3 merged-pull was shipped when network_id == posting_id (pre-
v0.6.1), so adding our_node_id to the pull query's follows list was
enough to trigger recipient-match on DMs. v0.6.1 broke that:
- Fresh installs generate independent network + posting keys; DMs are
encrypted to posting id, but the pull query carried network id.
Recipient-match never fired. Non-follower DMs never reached.
- Upgraders rotated the network key; DMs addressed to the old key
(now the default posting id) never matched either.
Fix: pull-request builders now include every entry from
list_posting_identities() in query_list. Network id is omitted — it
is never an author and never a wrapped_key.recipient, so adding it
would only leak the boundary without ever matching.
Four call sites fixed: Network::pull_from_peer, and
ConnectionManager::{pull_from_peer, pull_from_peer_unlocked, and the
post-notification-triggered pull path}.

AndroidFs trait must be in scope for show_open_file_dialog / read

Reset All Data:
- Sentinel now written at the app-level data_dir instead of the
active identity's subdir. On Android the subdir path was never
checked at startup, so reset silently did nothing.
- On detection, wipe EVERYTHING under the app data_dir: identity.key,
itsgoin.db + WAL + SHM, blobs, all identity subdirs. Next launch
is truly fresh — new network key, new posting key, no prior data.
First-run name:
- Display name is optional. Blank submits as anonymous.
- First-run modal + profile overlay placeholder updated to say
"Display name (optional)".
Android file picker:
- pick_file on Android now uses tauri-plugin-android-fs'
show_open_file_dialog (Storage Access Framework OPEN_DOCUMENT).
Read the picked URI's bytes, stage them in the app's private cache
as a timestamped file, return the staged path so existing
import_* code can read it as a regular filesystem path.
- Zip filter passes application/zip + application/octet-stream (some
file providers report the latter for .zip).
Android auto-backup off:
- AndroidManifest: allowBackup="false", fullBackupContent="false",
dataExtractionRules pointing at new data_extraction_rules.xml
- New data_extraction_rules.xml excludes all domains from both
cloud-backup and device-transfer. Prior default (allowBackup=true)
silently replicated identity.key to Google Drive for any user with
cloud backup on — which effectively published the root secret to
a third party without asking. Users who want off-device backup use
Settings -> Export (explicit zip they control).
Import as personas:
- New import_as_personas function in core/import.rs + new
import_as_personas_cmd Tauri IPC.
- Reads identity.key from the bundle and adds it to posting_identities
as a persona. Also reads posting_identities.json (v0.6+ bundles)
and adds each entry. Dedupes by node_id.
- Posts stay AS-AUTHORED — original post_id, original author,
original signatures, original wrapped_key recipients. No
re-encryption. Content encrypted to any of the imported keys
becomes decryptable because we now hold the secrets.
- Blobs, follows, profiles copied across.
- If current device has <=1 posting identity (the fresh-install one)
and the bundle brings more, auto-switch the default to the first
imported persona. Covers first-run-then-import flow cleanly.
Import wizard UI:
- New default option: "Restore as personas" — posts keep original
authors; source's keys become personas you can post as.
- Old "Merge with decryption key" retained as "Consolidate under
current default persona (requires source key)" for the case where
a user intentionally abandons a persona.
- "Public posts only" and "Add as separate identity" retained.
deploy.sh made executable (chmod +x tracked).

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.

Mostly a framing refresh — the underlying architecture description
matches what v0.6.0 actually does. Per-subsection status badges so a
reader can see at a glance what's shipped, what's partial, and
what's deferred:
- §28.1 two-layer identity: Shipped
- §28.2 persona types: Shipped (minus ephemeral — folded into §28.4)
- §28.3 multi-device: Partial (export/import works; no QR linking UX)
- §28.4 ephemeral rotating DM IDs: Deferred + connection-model
rationale written out
- §28.5 CDN holder sets: Shipped, with drop-migration note
- §28.6 DM privacy: Shipped (2 of 3 mechanisms; comment-as-intro
machinery exists but no dedicated UX yet)
- §28.7 user-facing: split into Shipped and Not-yet items
- §28.8 key safety: Shipped (unchanged content)
- §28.9 phase-by-phase rollout: each phase tagged Shipped v0.6.0
except Phase 6 (Deferred)
Final paragraph replaces the old "beta and stable are separate
networks" language with the hard-fork framing and a link to the
upgrade path on the download page.

The v0.5 export format matured in v0.5.1; exports from 0.5.0 or earlier
won't import cleanly into v0.6. Add a secondary warning pointing those
users to a two-hop upgrade via v0.5.3, with direct links to the archived
0.5.3 artifacts that remain on the server.

Phases 1-5 of the Identity Architecture rollout are on master; Phase 6
(rotating DM IDs) is deferred. This bumps the protocol-breaking
release: v0.5 and v0.6 cannot interoperate.
Packaging:
- Cargo + tauri.conf: 0.5.3 -> 0.6.0
- deploy.sh: drop -beta filename suffix
- download.html: single v0.6.0 section with fork notice at the top;
changelog entry summarising the five phases and the schema migration;
Phase 6's rotating-DM-ID status noted as deferred

Settings > Personas:
- List all held posting identities with display_name + truncated nodeId
- Default badge; Set-default / Delete buttons per non-default persona
- "New Persona" modal prompts for a display name and creates via IPC
Compose box:
- A #persona-select dropdown appears when 2+ personas exist
- doPost attaches postingIdHex to create_post / create_post_with_files
when a non-default persona is selected
Tauri:
- create_post and create_post_with_files take an optional
posting_id_hex; when present they route through create_post_as,
otherwise through the default create_post_with_visibility
- PostDto gains asPersona: name of the authoring posting identity if
the author matches any of our held personas
- is_me now recognises ALL our posting identities, not just the
network key (both post_to_dto and post_to_dto_batch)
Feed:
- Per-post "(you) as <PersonaName>" label on own posts authored by a
non-default persona
- Persona filter pill row above the feed (hidden for single-persona
users); pills toggle between All and each persona; matches when
post.author or post.recipients contains the selected posting id
- Applied after loadFeed initial render and after appendFeedPage so
filter survives infinite-scroll
App.js:
- personasCache + loadPersonas() loaded on startup so compose picker
is populated before the Feed tab mounts
- loadPersonas() also called when Settings tab opens
Backend was unchanged; only the UI and IPC surface expanded.

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.

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

A non-follower can now receive DMs addressed to them via a normal pull
cycle, with no distinguishable "searching for DMs" traffic pattern —
the pull query is a uniform list of NodeIds that the server matches
against both authors and wrapped-key recipients.
Schema (migrations on first 0.6.2 launch):
- New post_recipients(post_id, recipient) index table with index on
recipient column
- Seed migration scans existing encrypted posts, extracts recipients
and group members from visibility JSON, populates the index
Write path:
- store_post_with_visibility / store_post_with_intent populate
post_recipients on successful insert
- update_post_visibility rebuilds the index for the updated post
- apply_delete cascade-removes post_recipients entries
Server pull handler (should_send_post):
- Renamed semantic: requester_follows → query_list. Contains every
NodeId the client wants posts for (follows + own NodeId).
- Encrypted/GroupEncrypted posts match if ANY recipient / group
member is in query_list (previously only if == requester).
- Wire protocol unchanged — the same PullSyncRequestPayload.follows
field now carries both follow targets and own NodeId indistinguishably.
Client pull paths (all three call sites in network.rs + connection.rs):
- Always append own NodeId to the query list before sending pull sync.
Storage helper:
- get_post_ids_for_recipients(nids) — bulk IN-match using the
idx_post_recipients_recipient index, for future SQL-side filtering.
Tests:
- should_send_post's recipient tests updated to pass query_list
containing requester (matches new contract).
- Added encrypted_post_matches_via_query_list_even_for_third_party_recipient
proving the server matches on any recipient in the list, not just
the requester itself.
All 111 core tests pass. Smoke-tested end-to-end: A posts encrypted
DM to B; B connects + syncs; B decrypts and reads DM; both sides'
post_recipients correctly populated on store.

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.

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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
New flat per-file holder set replaces the directional upstream/downstream
trees. Keyed by 32-byte content-addressed file_id (works for both PostId
and blob CID). LRU-capped at 5 holders per file on touch.
- HolderDirection enum (Sent/Received/Both) — tracked for potential
reuse, not load-bearing for propagation
- touch_file_holder / get_file_holders / delete_file_holders
- seed_file_holders_from_legacy: one-time idempotent seed from
post_upstream, post_downstream, blob_upstream, blob_downstream so
users upgrading from 0.6.0 don't start with empty holder sets
Table and methods land here; call-site refactor and legacy-table drop
follow in subsequent commits within this phase.

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.

Explicit stance: 0.6.x beta does not interoperate with 0.5 stable.
Removes dual-write migration machinery, mixed-version wire handlers,
and cross-track testing. Users cross tracks via export/import bundle.
Preserves: local upgrade path for user's own data; serde-default wire
field additions; identity bundle format compat.

- Promote 0.5.3 to stable on download page
- "Coming in Beta" section describes 0.6.x privacy features
- Add design.html §28: Identity Architecture (Planned) — network/posting
ID split, multi-persona, ephemeral DM IDs, file-holder CDN, CDN-only
DM privacy
- IMPLEMENTATION_PLAN_0.6.md: phased rollout across 0.6.0 through 0.6.5,
each backward compatible, each a standalone release

Store the external address reported by peers via your_observed_addr in
initial exchange. Display it in Our Info panel with NAT classification.
Replaces reliance on iroh's pkarr/STUN for external address discovery
while keeping clear_address_lookup() (no dns.iroh.link publishing).

Shifted angle from "better social network" to "return to what it was."
Updated features (video/audio/files, Windows), removed aspirational claims,
reframed limitations as intentional design choices.

When anchor reports duplicate identity, sync pauses and a red banner
shows with a "Continue Anyway" button. Clicking it clears the flag and
starts all sync tasks. Handles false positives from network changes
(WiFi/cellular/VPN switches) without requiring complex staleness checks.

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)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Node::open_with_bind no longer runs bootstrap (anchor connect, NAT
probe, referrals). New run_bootstrap() method called from background
task after UI is live.
- Background tasks (pull cycle, diff cycle, etc.) start after bootstrap
completes, not during block_on.
- Feed no longer pre-loaded during welcome screen readiness check.
Ready button enables immediately after get_node_info succeeds.
- Feed loads on tab switch, not during startup.

- bundleMediaFramework: true — bundles full GStreamer plugin set in AppImage.
Fixes WebKit hang on video/audio (missing appsink/autoaudiosink plugins).
MSDK/VA plugins removed post-build to avoid Ubuntu DMA assertion crash.
- Import creates complete posts: BlobHeader, VisibilityIntent, pinned blobs,
self-follow. Imported posts now indistinguishable from locally created ones.
- First-run chooser: Start Fresh or Import Identity on fresh install only.
Profile setup shown for existing identities without display name.
- File pickers: native Browse buttons on export (folder) and import (ZIP)
via tauri-plugin-dialog.
- Export path: relative paths resolved against home dir.
- Lightbox close: only on overlay/image click, not inner form content.
- Growth loop skips self as N2 candidate.
- Node shutdown on identity switch (prevents zombie background tasks).
- media-src CSP includes asset protocol.

- First-run: show Start Fresh / Import chooser only when single auto-created
identity with no profile (not on every boot without a display name).
- Identity switch: shut down old node's endpoint before starting new one.
Fixes lockup after multiple switches (zombie background tasks).
- File picker: native Browse buttons on export (folder) and import (ZIP file)
via tauri-plugin-dialog.
- Export path: resolve relative paths against home dir (was using process cwd).
- Lightbox close: only close on overlay/image click, not inner form content.

The global click handler was removing any .image-lightbox on any click
inside it, which broke export/import/identity wizards (clicking radio
buttons or text inputs closed the wizard). Now only closes on overlay
background click or image click, preserving form interaction.

- handle_pull_request: extracted to static method, conn_mgr lock no longer
held during network I/O (read request + write response)
- handle_address_request: inlined at call site with brief lock to gather
data, response written after lock release
- handle_session_relay: capacity check + target lookup under brief lock,
rejection write moved outside lock scope

- 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).

Merge-with-key: decrypt exported posts using original identity seed, re-create
under current identity with prior_author in BlobHeader for provenance tracking.
Download page restructured with stable (v0.4.4) + beta (v0.5.0-beta) sections.
Version bumped across all crates.

Export (export.rs): ZIP archive with auto-chunking at 4GB. Four scopes:
identity only, posts only, posts+identity, everything (posts+key+follows+
profiles+settings). Includes blobs. Manifest JSON tracks metadata.
Import (import.rs): Read ZIP summary without importing (preview).
Import public posts into current identity with new PostIds + original
timestamps. Import as new identity (creates identity subdir from key).
Uses spawn_blocking for ZIP I/O to avoid Send issues with ZipArchive.
Tauri IPC: export_data, import_summary, import_public_posts,
import_as_new_identity commands. IdentityManager.base_dir() getter.
Frontend: Export wizard lightbox with scope radio buttons + output dir.
Import wizard with ZIP path, preview summary, action selection.

Security: identity.key written with 0600 permissions (Unix). Docker bridge
IPs (172.17-31.x) filtered from is_shareable_addr to prevent topology
disclosure in relay introductions.
Lock contention: ManifestPush relay and DeleteRecord CDN notify now gather
connections under lock, then send outside lock.
UI: syncBtn null guard prevents crash on hidden element.
Documentation: design.html version badge updated to v0.4.4. Self Last
Encounter threshold corrected from 3h to 4h. Multi-Device Identity section
rewritten for multi-identity-per-device (complete) + multi-device (planned)
+ post merge (planned). MEMORY.md updated to v0.4.4+ status.

New Tauri commands: list_identities, create_identity, switch_identity,
delete_identity, import_identity_key, get_active_identity.
Settings UI: Identities section with list (active indicator, switch/delete
buttons), Create New Identity lightbox, Import Identity Key lightbox.
Export/Import buttons as placeholders for Phase 2/3.
Identity switch does hot-swap: tears down old Node, starts new one with
all background tasks, swaps AppNode RwLock. Frontend reloads after switch.
