Make 'announcement' a real channel type, resolving the contradiction where it was documented and offered by the admin API but hard-rejected by the migration-013 DB triggers. Model: announcement channels are readable like text channels (same READ_MESSAGES visibility), but posting is restricted to users with MANAGE_MESSAGES — no new permission bit, migration, or client permission plumbing needed. Server: - migrations/016: recreate the channel-type triggers to allow text/voice/announcement/dm. - service/message.go: checkSendPermission now takes the channel type and rejects posts to announcement channels from users lacking MANAGE_MESSAGES (SendMessage + CanPost paths). Added a service test. - Unread counts: ready-payload builder (ws/serve.go) and GetChannelUnreadCounts (db) now include announcement channels alongside text, so they track unread/last-message like text channels. Client: - ChannelSidebar renders announcement channels with a megaphone icon (added to the icon set) instead of the '#' text prefix; they otherwise behave like text channels (already typed in ChannelType). Specs + trackers (api.md, protocol.md, schema.md incl. migration 016, architecture/data-model.md, audit A-2026-07-01, decisions D1) updated. Verified: go build ./...; go test ./service ./db ./ws ./api ./admin; sqlc-verify; client tsc + oxlint + prettier clean.

OwnCord Architecture Blueprints
Verified against: commit ddc49f0, 2026-07-19
Companion audit: docs/audit-2026-07-19.md
This directory is the curated architectural map of OwnCord — the "blueprints" for the whole system. Every diagram is a Mermaid fenced block (GitHub renders these natively) followed by a prose explanation and a Source of truth file list.
Index
| Doc | Diagrams | Covers |
|---|---|---|
| system-overview.md | D1 System context, D8 Deployment topology | All processes, trust boundaries, ports, single-instance constraints |
| server.md | D2 Server package map, D3 REST request lifecycle | Go package structure, DB-access styles, middleware chain |
| websocket.md | D4 WS connect / replay / dispatch | Real-time engine: auth handshake, 3-tier reconnect replay, backpressure, V1/V2 dispatch |
| data-model.md | D5 Entity-relationship overview | All 23 tables from migrations 001–015, grouped by domain |
| voice-e2ee.md | D6 Voice + E2EE flow | LiveKit token flow, loopback TLS tunnel, ECDH key-holder relay |
| client.md | D7 Client module map | Tauri client: bootstrap, dispatcher, stores, Rust sidecars |
Maintenance rule
These documents are curated, not generated. The rule that keeps them honest:
If a PR changes the structure of anything listed in a diagram's Source of truth list (new package, new table, new message type, changed flow), that PR updates the corresponding diagram in the same change.
Diagrams reference stable identifiers (package names, table names, message-type strings) rather than line numbers wherever possible. Line-number evidence lives in the dated audit reports, which are point-in-time snapshots by design.
Relationship to other docs
docs/api.md,docs/protocol.md,docs/schema.mdare the reference specs (request/response shapes, wire formats, DDL). These blueprints describe structure and flow, not payload shapes. Known drift between the specs and the code is catalogued in audit-2026-07-19.md §2.docs/client-architecture.mdpredates the abandonment of the Solid.js migration; client.md reflects the current state.
