J3vbandClaude Fable 5 1fe3df7962 test(b2-1): capture the epoch-1 protocol fixtures and retire S-15 (#1435)
* refactor(protocol): retire reserved voice_speakers and member_leave (S-15)

Neither type was ever emitted by the server; B2-1 clears them from the
schema before the epoch-1 wire fixtures are captured, so the frozen epoch
does not carry two dead message types.

Client: dropped the dead `ws.on(MEMBER_LEAVE)` / `ws.on(VOICE_SPEAKERS)`
dispatcher handlers, the `MemberLeavePayload` type and both `ServerMessage`
union members, and the tests that only exercised those WS paths.
`removeMember` (member_ban) and `setSpeakers` (LiveKit ActiveSpeakers) stay
live and keep their direct unit tests.

* test(ws): capture the epoch-1 wire fixtures

alpha.4 is the last client on the pre-epoch wire and B2-2 adds a protocol
epoch to the auth handshake next, so record what epoch 1 actually looks
like while it is still observable.

TestEpoch1Fixtures drives eleven journeys through the ws package's
in-process hub harness (full migrations, real hub, httptest WebSocket
server) and compares each journey's per-connection frame sequence with a
transcript under protocol/fixtures/epoch-1/:

- fresh-connect, auth-failure, ping
- chat-send-fanout, chat-edit-delete, reaction-add-remove
- typing, mark-read, dm-send
- resume-replay (last_seq + buffer-tier replay burst)
- voice-join-e2ee-leave (join, both voice_state forms, announce and
  offer relay, leave)

Volatile values are replaced by typed placeholders before both writing
and comparison -- any key that is id/seq/last_seq, ends in _id (except
channel_id and role_id) or _at, is timestamp/ts/last_seen, or contains
token, becomes "<class:json-type>" so a field that changes type is still
a diff, while everything else is compared verbatim.

* test(client): pin the epoch-1 auth frame contract

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test(updater): pin the epoch-1 manifest and client-update shapes

* test(ws): harden the epoch-1 fixtures against trailing frames and absent optionals

Every journey now ends with the ping/pong barrier on each recorded
connection, so a frame the server emits after the last read fails as
`expected "pong", got "X"` instead of going unrecorded; auth-failure
asserts the StatusPolicyViolation close instead, its socket being gone.

alice carries a display name, avatar, about text, custom status, identity
public key and an announce signature (bob carries none), so every optional
field is frozen in its present form as well as its absent one — a rename or
a retype of display_name or identity_public_key now moves a fixture.

The typing journey focuses the channel on "a" before typing: without the
subscription registerNow only makes for a focused client, its ping/pong
proved nothing about excludeUserID.

Comment fixes: the escaped placeholder form MarshalIndent would write, the
real (headroom) reason for the raised read limit, a note that bare id and
active_channel_id are normalised by design, and a .prettierignore line
saying these fixtures are verified by the Go comparison, not by git diff.

* docs(protocol): document the epoch-1 fixtures

* docs(protocol): match the epoch-1 wire where the fixtures contradicted the doc

- voice_state: note the unsequenced relay-to-joiner form (table row + section)
- auth_error: correct the example message and list the real rejection messages
- member_join/presence connect example: add the seq both frames actually carry
- chat_message.user: document display_name
- voice_join reply order: state that the joiner's own voice_state broadcast is not ordered against the other three frames

* test(ws): freeze the null forms of auth_ok and member_join user fields

buildAuthOK emits display_name/about/custom_status/avatar as
always-present nulls, but only alice — who has all four set — ever
authenticated on a recorded connection, so the fixtures froze those
fields in their populated form alone. A rename, a retype or a dropped
null would have moved nothing, on the very frame B2-2 edits.

fresh-connect now records bob's handshake too, on a second connection:
his auth_ok carries the four nulls, his member_join carries avatar null
with display_name and identity_public_key omitted, and alice — idle by
then, so her reads stay in hub order — records the same pair as an
already-connected observer sees it. In voice-join-e2ee-leave bob answers
alice's signed announce with a legacy unsigned one, which freezes the
absent form of signature next to her present one. The auth frames the
test writes now carry the correlation id the real client stamps on every
frame (ws.ts send()); normalisation renders it <id:string>.

expectClosed also asserts the close reason ("authentication failed"),
not just code 1008 — HP-2 asks for both.

Comment precision, no behaviour change: the barrier guarantee now states
that pong may overtake a pending LOW-priority frame (writePump) and that
no journey is affected because every barrier is sent on an idle
connection; the ping-budget ceiling is six connections, not four; the
typing journey cites handleChannelFocusV2 rather than registerNow as the
subscribe site; resume-replay's b barrier explains why moving it past
the resume would be a flake, not a fix; and the header notes that
normalisation hides that chat_send_ok.id echoes the request id.

The client contract test's cited range for ws.ts's send() call is
441-453, not 441-454.

* docs(protocol): shape-not-value fixture rule, voice_max_video default, auth close code

The fixture rule read "a fixture may only change with an epoch bump",
which is false for the seeded values the transcripts record verbatim:
role permission masks and colours, motd, server_name, voice_max_video,
the voice_config preset. A migration that changes a default mask diffs
fresh-connect.json, and the README told the author to revert a change
that never touched the wire.

Split the rule along shape versus value. A key set, a JSON type, a key
appearing or disappearing, or per-connection frame order is a protocol
change and earns fixtures/epoch-<n+1>/. A seeded default value is a seed
change: regenerate in the same PR and read the diff frame by frame.
Normalising those values is explicitly not the answer — a placeholder
over a mask or over an enum such as voice_config.threshold_mode would
hide the drift the fixtures exist to catch.

Two wire facts corrected against the fixtures:

- voice_max_video on an unconfigured channel is 25, not 0 (migration
  004 is DEFAULT 25); the doc listed it among the zero values.
- auth_error is followed by a close with code 1008 (policy violation)
  and reason "authentication failed" (serve.go:128), which the doc left
  as "closes the connection".

Also: voice_speakers moves from discord-parity's "still dead" list to
"came off the list" — it was retired earlier on this branch. And Kick
says sessions are revoked and sockets drop on the next sweep, which is
what ForceLogout does (moderation.go:236); it does not cut sockets.

* docs(protocol): fixture rule covers enum vocabularies; header comment precision

Re-check minors from the whole-branch review: a fixed-vocabulary value the client switches on is shape, not a seeded value; drop the false 'new default channel' clause (the seed asserts channel ids); the low-priority frame is presence_update, not connect presence.

* docs(plans): record B2-1 evidence for HP-2 (PR #1435, fixture commit SHAs)

* docs(protocol): additive changes stay within an epoch; bump only for what old clients cannot process

Codex review on #1435: B2-2 keeps protocol_epoch = 1 while adding auth/ready/auth_error fields, which the previous wording would have called a break to revert. An epoch is a compatibility boundary, not a snapshot: additive keys regenerate in the same PR and are documented; removals, renames, retypes, dropped frames and reordering bump the epoch. The plan's B2-1 evidence records the refinement and hands B2-2/B2-4 the open questions (additive-tolerant replay of the epoch-1 transcript; epoch 0 vs 1 naming).

* test(client): compare auth-frame key sets order-independently

Codex review on #1435: Object.keys preserves insertion order, so a harmless property reorder in ws.ts would fail the pin. Key order has no wire meaning; the Go fixtures already compare with sorted keys. Sort both sides.

OwnCord Client UX Specification (target state)

Verified against: commit 5630aa1, 2026-08-04 Companion: ../client.md (structural module map) · ../../audit-2026-08-04-docs-and-coverage.md

This directory specifies how the Tauri client should behave — what every UI step does, and how each view reacts to server events, permission state, and failure. Unlike client.md, which maps the code as-built, these documents are prescriptive (to-be): they describe the intended target UX. Where today's code diverges, each flow carries a ⚠ Current gap callout — so this set doubles as a UX improvement backlog. Gaps are grounded in real file:line references from the client.

Scope. This is a behavior spec, not a visual design spec. It defines states, transitions, events, and reactions — not pixel layout, spacing, or color. Those live in src/styles/tokens.css and the component CSS.

Documents

Doc Covers
connection-and-auth.md App boot, server profiles, connect/health, login, TOTP, register-by-invite, the connected handshake, reconnect, and cert-TOFU trust prompts
messaging.md Composer + send (optimistic), edit/delete, reactions, attachments, replies, pins, search, read/unread, slow-mode, announcement read-only gating

settings-and-admin.md Settings tabs, profile/password/2FA/delete-account, appearance/theming, the inline admin surface (ban/kick/roles, channel CRUD, invites), and the updater

The cross-cutting vocabulary and global reaction matrices below apply to every document; the per-flow docs reference them rather than repeating them.


1. View-state vocabulary

Every data-bearing view must be able to represent each of these states and must choose a defined presentation for each (a view may legitimately collapse some — e.g. a view that can never be empty — but that must be a decision, not an omission):

State Meaning Default presentation
loading A fetch/subscription is in flight and no cached data is shown yet Skeleton or inline spinner in the view's own region — never a full-screen blocker except the initial connected handshake
ready Data present and current The normal view
empty Fetch succeeded, zero items A labelled empty state with a one-line "what goes here / what to do next" hint
error Fetch/action failed Inline error with a Retry affordance for recoverable errors; a toast only for fire-and-forget actions
stale Data shown but known out of date (e.g. during reconnect) The normal view plus a non-blocking status hint (connection banner); interactions that require a live socket are disabled with a reason
permission-denied The user may see the view but not act The view renders read-only; the disallowed control is disabled with a visible reason, never hidden silently and never enabled-then-rejected
offline No live socket Live-only controls disabled with the connection status surfaced

Principle — no silent states. Every terminal outcome (success, empty, failure, denial) produces some observable feedback. A control that will be rejected by the server must be pre-disabled with a reason; an action that succeeds without a visible result must emit a confirmation.


2. Feedback primitives

The client has a fixed set of feedback surfaces. Each has one job; pick by the decision table, don't improvise.

Primitive Source Use for Do not use for
Toast (info/success/error, 5 s auto-dismiss, max 5) lib/toast.tscomponents/Toast.ts Transient results of an explicit user action (sent, copied, saved, "couldn't reach server") Anything the user must act on; anything that must survive navigation
Inline field error per-form Validation and per-field server rejections (bad password, weak input) Global/connection state
Inline section error + Retry per-view A failed load of a view's own data (messages, invites, pins) One-shot actions (use a toast)
Persistent banner components/ServerBanner.ts (reconnect/restart), ad-hoc cert banner Connection status: reconnecting, server-restart countdown, first-trust cert notice Per-action results
Blocking modal lib/modalFactory.ts (+ CertMismatchModal) Decisions that must be made before proceeding: cert mismatch, destructive confirm Routine feedback; anything dismissable-by-ignoring
Two-click / inline confirm AdminActions.ts withConfirmation, PendingDeleteManager Reversible-ish destructive actions in dense menus (kick, ban, delete channel, delete message) Irreversible account-level actions (use a modal with typed confirm)
Disabled control + reason per-control Actions not currently permitted (offline, no permission, slow-mode cooldown, upload in flight) Errors that already happened
Transient-error store (ui.store.setTransientError) survives navigation A message that must appear on the connect page after a forced disconnect (banned, kicked, restart) In-session messaging (use a toast)

3. Connection status is a first-class, observable state

Every live-only interaction keys off one connection status. Target: a single source of truth in ui.store.connectionStatus (connected | reconnecting | disconnected), written from the WS client's onStateChange, and read by any control that needs a live socket.

✓ Implemented (2026-07). ui.store.connectionStatus is now the single source of truth: main.ts calls wireConnectionStatus(ws), whose writer lives in lib/dispatcher.ts (ws.onStateChangetoConnectionStatussetConnectionStatus), mapping the internal 5-state machine onto the 3-state status (connecting / authenticating read as reconnecting, since a reconnect cycle passes through them). Consumers subscribe to the store instead of wiring ad-hoc callbacks: the reconnect banner (MainPage, synced at mount and now also showing "Disconnected" instead of going stale), the composer gating (ChannelController, "Reconnecting…" / "Not connected" per the table), and the presence picker (UserBar — previously dead in production because SidebarArea never passed it a ws; it now gates on the store and receives the ws send path). The one-shot connected-overlay wiring in main.ts stays on ws.onStateChange deliberately — it needs the exact internal transition. The voice column is now wired too: the VoiceWidget freezes its in-call controls (disabled + a "Reconnecting…" / "Not connected" reason) while connectionStatus !== "connected", and the join affordance itself — the voice-channel row in the ChannelSidebar — takes the same disabled-with-reason state (.disabled class, aria-disabled, a "Reconnecting…" / "Not connected" title) and its click becomes a no-op, so joining/leaving is visibly gated, not a silent dead click. The join/leave callbacks (VoiceCallbacks.ts) still refuse to fire voice_join/voice_leave over a down socket as a defensive backstop. LiveKit's own reconnection keeps retrying underneath — only the UI is gated, never LiveKit's machinery.

Status Composer / send Voice controls Presence picker Reconnect banner
connected enabled enabled enabled hidden
reconnecting disabled, "Reconnecting…" frozen, retrying underneath disabled visible, spinner
disconnected disabled torn down disabled visible or → connect page on fatal

4. Global event → reaction map

The dispatcher (src/lib/dispatcher.ts) is the single fan-in from the socket to the stores. Target: every inbound message type produces a defined store mutation and, where user-visible, a defined UI reaction. The per-flow docs detail each; this is the index.

Inbound event Store effect Target UI reaction
auth_ok auth.setAuth Advance handshake → ready overlay
auth_error ui.setTransientError + auth.clearAuth Return to connect page with the reason shown
ready bulk-load channels/roles/members/voice/dm Render main view; resolve the connected overlay
chat_message messages.addMessage (+ unread/DM/notify) Append; reconcile a pending optimistic row if it's our echo
chat_send_ok messages.confirmSend Mark the optimistic row sent (see gap in messaging.md)
chat_edited / chat_deleted messages.editMessage / deleteMessage In-place edit / tombstone
chat_bulk_deleted messages.bulkDeleteMessages Remove every purged row in one pass
reaction_update messages.updateReaction Toggle the pill + count, reflect me
typing members.setTyping (5 s auto-clear) Typing indicator
presence / member_update / user_update members.* Live member-list update
member_join / member_ban members.add/remove Member-list add/remove
channel_create / channel_update / channel_delete channels.* Sidebar update; redirect if the active channel was deleted
roles_update channels.setRoles Refresh name colors + permission-gated affordances
emoji_update emoji.setCustomEmoji Refresh picker, autocomplete, and rendered custom emoji
voice_state / voice_leave / voice_config voice.* Voice roster (speaking rings come from LiveKit's ActiveSpeakers, not the wire)
voice_moved / voice_disconnected voice.* + livekitSession Follow a mod move by rejoining the new channel / tear down after a mod kick with an error toast naming the reason
voice_token / voice_e2ee_* livekitSession.* Drive the voice-join + securing indicators
dm_channel_open / dm_channel_close dm.* DM list add/remove
server_restart ui.setTransientError Restart banner with countdown
error ui.setTransientError (+ clearAuth on BANNED) Map the code → the reaction in §5

call_incoming / call_declined are deliberately not routed through the dispatcher: MainPage.ts subscribes to them directly (page-scoped listeners) and drives the ring state machine in lib/call-ring.ts + components/IncomingCallBanner.ts.

✓ Implemented (2026-07). Error codes are no longer silently dropped for sends: the server echoes the request id on error replies, so SLOW_MODE, FORBIDDEN, RATE_LIMITED, BAD_REQUEST, etc. are mapped to the exact optimistic row that failed (retry offered), and chat_send_ok's message_id/timestamp now reconcile the pending row. See the optimistic lifecycle in messaging.md.


5. Error & permission reaction matrix

One canonical reaction per failure class, applied everywhere. Today error handling is per-call-site with no shared mapper (doFetch() in lib/api.ts centralizes only 401); this matrix is the target contract.

Class Source Target reaction
401 Unauthorized any REST call Global: clearAuth() → disconnect → connect page, with "Your session expired — sign in again." (centralized in api.ts + main.ts; since 2026-07 uploadFile honors it too, and the connect page shows the session-expired reason)
403 Forbidden (action) REST/WS Toast "You don't have permission to do that." and pre-disable the control so it can't be attempted again in that context
403 Suspended/Banned login REST / WS BANNED Transient-error store → connect page: "Your account has been suspended." Force logout, no reconnect
429 Rate-limited REST/WS RATE_LIMITED Non-destructive toast "You're doing that too fast — try again in a moment." Keep the user's input; re-enable the control after a short cooldown
Slow-mode WS SLOW_MODE Disable send with a live countdown in the composer; do not drop the drafted message
Validation (400) REST Inline field error with the server message (capped to a safe length — the login form caps at 200 chars in the handleFormSubmit() catch block, pages/connect-page/LoginForm.ts; apply everywhere)
Conflict/Not-found (404/409) REST/WS Contextual inline message + refresh the affected view (the target moved/vanished)
5xx / network REST Inline section error + Retry; for one-shot actions, a toast "Couldn't reach the server." Never a silent drop
Transport backpressure WS ws_send "channel full" Mark the optimistic row failed with Retry (✓ since 2026-07: ws.onSendFailure → dispatcher → markSendFailed with NETWORK/OFFLINE; id-less sends like heartbeats stay silent)
Cert first-use Rust cert-tofu: first_use Blocking trust modal (createCertFirstUseModal): the Rust proxy rejects the first connection rather than auto-pinning; Accept stores the pin and retries, Cancel leaves the server untrusted (already: the ws.onCertFirstUse(...) handler in main.ts)
Cert mismatch Rust cert-tofu: mismatch Blocking CertMismatchModal; Accept re-pins + reconnects, Reject disconnects + returns to connect (already: the ws.onCertMismatch(...) handler in main.ts)

6. Cross-cutting principles

  1. Optimistic where the user acts, authoritative where the server decides. Local actions (send, react, mute) reflect immediately with a pending marker, then reconcile against the server echo; on failure they roll back visibly with a retry — never silently.
  2. Permission is expressed as affordance, not as rejection. If the server will refuse, the client disables the control with a reason first. The announcement-channel composer is the canonical example (see messaging.md).
  3. Connection state gates live controls reactively (§3), not per-click.
  4. One reaction per failure class (§5), applied uniformly.
  5. No silent success and no silent failure (§1).

Maintenance rule

Same as the blueprint set: if a PR changes a client flow, event handler, or the set of states a view must represent, it updates the corresponding UX doc in the same change. These specs reference stable identifiers (event-type strings, store action names, component names) over line numbers; the file:line anchors in the gap callouts are point-in-time and dated by the header.
