New primitive: `VisibilityIntent::Announcement`, a public post whose
author MUST be the hardcoded bootstrap anchor posting identity
(`DEFAULT_ANCHOR_POSTING_ID`) and whose content carries an ed25519
signature by that key. Forged announcements (any other author, or
bad signature) are rejected by `control::receive_post` before storage
— they never enter the DB and never propagate via neighbor-manifest
diffs. Only the real anchor can publish announcements, and it does so
sparingly as part of the release deploy flow.
Uses release announcements to drive an in-app upgrade banner:
- Anchor publishes a signed `{category:release, version, channel,
download_url, ...}` post during every deploy.
- Clients receive it via the normal CDN; `apply_announcement_if_applicable`
stores the latest-per-category/channel in the settings kv, keyed
e.g. `announcement:release:stable`.
- Welcome screen checks storage on startup; if the stored release
version > CARGO_PKG_VERSION on the user's selected channel, a banner
appears with a Download button that opens the system browser.
- Settings gets "Updates" section with Stable / Beta radio + Check-now
button + current status line.
Core:
- `DEFAULT_ANCHOR_POSTING_ID: NodeId` constant (32 bytes, the anchor's
current posting id — `17af141956ae...`).
- New `VisibilityIntent::Announcement` variant; feed filters in all 6
`get_feed*` / `list_posts*` query sites updated to also exclude the
new intent AND the pre-existing `GroupKeyDistribute` intent.
- `types::AnnouncementContent` + `ReleaseAnnouncement` structs.
- `crypto::{sign,verify}_announcement` — length-prefixed field digest
with a "has release" 1-byte flag.
- New `announcement` module with `verify_announcement_post`,
`apply_announcement_if_applicable`, `latest_release`,
`build_announcement_post`, and a `StoredAnnouncement` envelope saved
to settings so the UI can render without a full post scan.
- `Node::publish_announcement` refuses to run unless the default posting
id equals the anchor constant — accidental use on client installs
fails loud.
Wire / receive:
- `control::receive_post` verifies announcement signatures upfront
alongside Control and Profile. Same pattern; same guarantees.
CLI one-shots (no daemon):
- `itsgoin <data_dir> --print-identity` — prints network_id +
default_posting_id, exits.
- `itsgoin <data_dir> --announce --ann-category release
--ann-channel stable --ann-version X --ann-title ... --ann-body ...
--ann-url https://itsgoin.com/download.html` — builds + stores +
propagates the signed post, exits.
deploy.sh:
- Now runs the announce one-shot inside the anchor-restart window
(after binary swap, before start). The DB is free during that gap,
so the one-shot can write without conflicting with the running
daemon. The restarted daemon loads all storage on boot and serves
the new announcement to pulling peers.
Tauri IPC:
- `check_release_announcement(channel)` → Option<ReleaseAnnouncementDto>
— returns None when up-to-date.
- `get_update_channel` / `set_update_channel(channel)` — persists in
settings kv key `ui_update_channel`; defaults to stable.
- `open_url_external(url)` — desktop-only (xdg-open / open / cmd start);
refuses non-http(s) URLs. Android needs the opener plugin — TODO.
Frontend:
- Upgrade banner on the welcome screen, populated by
`loadUpgradeBanner()`. Hidden when no newer release is known.
- Settings → Updates section with Stable/Beta radio + Check-now button
+ current status line.
Tests: announcement signature roundtrip; non-anchor author rejection;
non-announcement intent is a no-op. 124 / 124 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.
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.
