J3vbandClaude Opus 5 2a37f386f9 B1-3: repository hygiene gates (RL-19 / L-13, S-05) (#1414)
* chore(format): one Prettier config at the repository root

Every formatting rule in this repository lived under Client/ and covered
exactly two globs: Client/src/**/*.ts and Client/tests/**/*.ts. Root Markdown,
all of docs/, every YAML and JSON, all CSS, the root scripts and
tools/mcp-introspect were formatted by nothing. There was no .editorconfig.

The obvious fix -- a second Prettier config at the root for "everything else"
-- gives two configs and two ignore files that can silently disagree about the
same file. So the root takes ownership instead: config, ignore file and gate
move up, and Client/ folds in. Client's inline "prettier" block, its
.prettierignore, its format/format:check scripts and its now-unused prettier
devDependency are all deleted; knip would have failed client-check on that last
one.

The .prettierrc.json values are lifted byte-for-byte from Client/package.json,
which is what keeps the reformat commit free of client TypeScript churn: 87
tracked files need reformatting and not one of them is under Client/src or
Client/tests.

.prettierignore carries only what .gitignore does not. Prettier 3 reads the
root .gitignore by default, so node_modules/, dist/, coverage/,
Client/src/generated/ and docs/security-findings/ need no entry. It does NOT
read nested .gitignore files, which is why .remember/ is listed explicitly --
38 untracked per-machine scratch files were otherwise able to turn a shared
gate red. graphify-out/ is listed because its seven files are tracked and
.graphify_labels.json is signed byte-for-byte by its .sig, so formatting it
would silently invalidate the signature.

check:hygiene is registered in scripts/run.mjs and folded into check and
release:preflight. It deliberately contains no `gofmt -l` step: gofmt -l prints
offenders and still exits 0, so it cannot fail a build. Go formatting is
enforced separately.

shellcheck and actionlint take their file lists from `git ls-files`, never a
filesystem glob -- .claude/worktrees/ holds a gitignored pre-flatten copy of
the tree with three .sh files a glob would happily lint.

This commit leaves the tree non-conformant on purpose. The reformat is the next
commit, so the 87-file diff is reviewable separately from the rule that caused
it.

Not included: editorconfig-checker. .editorconfig is the editor baseline the
audit asked for; Prettier, gofmt and rustfmt already fail CI on the same
indentation and newline rules, so a fourth tool checking them again is a gate
with no failure mode of its own.

Verified: `npx prettier --check .` names 87 tracked files and zero untracked
ones; the same command listed 38 .remember/ scratch files before the ignore
entry and none after. `node scripts/run.mjs --list` resolves check:hygiene to 8
shell targets and 4 workflow targets. Both package.json files parse.

* chore(format): reformat the tree to the repository Prettier rules

Mechanical. This commit is `npx prettier --write .` and nothing else -- the
rule that caused it landed in the previous commit so this diff can be reviewed
as a transformation rather than as 84 files of hunks.

84 tracked files: 54 Markdown, 7 .mjs, 7 JSON, 6 YAML, 4 .js, 3 CSS, 2
TypeScript (the two Playwright configs at Client's root, which the old
Client/src + Client/tests globs never covered). No file under Client/src or
Client/tests moves, because .prettierrc.json carries Client's former inline
values byte-for-byte.

Prettier rewrote 87 files, not 84. The three in .github/ISSUE_TEMPLATE/ had
CRLF on disk and differ only in line endings, which .gitattributes
(`* text=auto eol=lf`) already normalises, so their committed blobs are
unchanged. Worth knowing before someone reconciles the two numbers.

The largest single diff is .superpowers/findings-ledger.json at 7976 lines
rewritten. That is safe to format: nothing writes the ledger programmatically
-- render-ledger.mjs reads it and writes only FINDINGS.md -- so no tool will
fight Prettier over its style on the next hunt. FINDINGS.md itself is ignored
as generated.

Verified: `npx prettier --check .` reports "All matched files use Prettier code
style", so the pass is both complete and idempotent. All 7 reformatted JSON
files were parsed before and after and compared as values: semantically
identical, zero content changes. `node .superpowers/render-ledger.mjs --check`
still reports 348 valid findings and leaves FINDINGS.md untouched.
`node scripts/check-doc-counts.mjs` still passes its selftest and still agrees
on 27 claims across 9 watched documents -- table realignment did not break the
patterns it matches on. `node scripts/run.mjs --list` still parses.

* chore(lint): enforce Go formatting in the Server linter

S-05: repository-wide Go formatting was not a required gate. The only gofmt
enforcement anywhere was .githooks/pre-commit, which is opt-in per clone
(`npm run hooks:install`), only sees staged files, and warns-and-skips when
gofmt is off PATH.

The obvious fix -- a `gofmt -l` step in CI -- does not work: `gofmt -l` prints
its offenders and still exits 0, so the step passes no matter what it finds.
scripts/run.mjs has the same problem, which is why check:hygiene has no Go step
either.

So gofmt goes where it can actually fail something: Server/.golangci.yml. The
file was already `version: "2"` but had no `formatters:` block at all, so the
19 enabled linters ran with zero formatters. In v2 gofmt/gofumpt/goimports
moved out of `linters.enable` into their own section with its own exclusions.
Adding it there means the gate reports through the Lint step of "Server Build &
Test", which is already pinned as required on dev -- no new job and no new pin.
Every tracked .go file is under Server/ (551 of them, one go.mod), so
Server-scoped is repository-wide here.

One file was genuinely misformatted: a one-space struct field alignment in
Server/admin/handlers_users_broadcast_test.go, fixed in the same commit because
a single line does not need its own reformat commit.

Trap worth recording: `gofmt -l .` on a Windows working tree lists every file
that has CRLF on disk, because gofmt normalises line endings. That reported 18
offenders here, 17 of them ghosts. The blobs are all LF -- .gitattributes
forces `eol=lf` -- so CI never saw them, and the honest test is to run gofmt
over `git show HEAD:<file>` rather than the working copy. Doing that across all
551 tracked Go files found exactly the one real offender above.

Verified both directions with golangci-lint v2 locally: `golangci-lint run
./...` reports 0 issues on the formatted tree; appending a misformatted
function to Server/auth/constants.go produces 2 gofmt findings; appending the
same misformatted function to Server/db/dbgen/admin.sql.go produces 0, so the
exclusion holds. Both files restored and verified clean afterwards.

* fix(scripts): escape the NUL separator instead of embedding one

The `tracked()` helper added earlier in this branch splits `git ls-files -z`
output on NUL. The separator was written as a literal NUL byte rather than the
two-character JavaScript escape, so scripts/run.mjs became a binary file: `git
diff` refused to show it, `grep` reported "Binary file matches" instead of the
line, and `* text=auto` in .gitattributes stops normalising line endings for a
blob it detects as binary.

The code worked -- splitting on a raw NUL and splitting on "\0" are the same
operation -- which is exactly why this is worth fixing before it is inherited.
A source file that tooling classifies as binary is a file nobody can review.

Verified: zero NUL bytes remain, `grep -n "split("` now prints line 50 instead
of "Binary file matches", `node scripts/run.mjs --list` still resolves the same
8 shell and 4 workflow targets, and prettier still reports the file clean.

* chore(lint): enforce Rust formatting

Rust had no formatting gate of any kind: no rustfmt.toml, no `cargo fmt`
anywhere in CI, in scripts/run.mjs, in the Makefile or in the git hooks. Clippy
was the only Rust gate, and clippy does not check layout.

`cargo fmt --all -- --check` now runs in the rust-tests job, ahead of clippy: a
formatting failure is cheap to produce and cheap to fix, and there is no reason
to spend a clippy pass to surface one. The stable toolchain in that job
requested `components: clippy` only, so rustfmt is added there.

Only that job. ci.yml has a second, byte-identical `Install Rust` block in
tauri-build; it stays clippy-only, because a full desktop build is the wrong
place to discover a misplaced brace.

No rustfmt.toml. The default profile is the point of a baseline -- a config
file here would be a second opinion about style with nothing to say.
Client/src-tauri is a single `[package]`, not a workspace, so `--all` is a
safeguard against a future member rather than a fan-out today.

Verified: `node scripts/run.mjs --list` resolves check:rust to three steps with
`cargo fmt --all -- --check` first, `npm run format` now also runs `cargo fmt
--all`, and prettier reports ci.yml, run.mjs and the ci-check skill clean.
`cargo fmt --all -- --check` currently fails on 13 files -- that is the
reformat, and it is the next commit.

* chore(format): reformat the Rust crate to rustfmt defaults

Mechanical. This commit is `cargo fmt --all` and nothing else; the gate that
demands it landed in the previous commit so this diff is reviewable on its own.

13 of the 17 tracked .rs files, +343/-164. The crate had never been formatted,
so the changes are the usual first-run set: aligned trailing comments collapsed
to single spaces, single-element slice literals folded onto one line, long
method chains broken across lines, closure bodies expanded into blocks.

Verified: `cargo fmt --all -- --check` is clean, so the pass is complete and
idempotent. `cargo clippy --all-targets -- -D warnings` finishes with no
warnings, and `cargo test --lib` reports 115 passed / 0 failed -- identical to
before the reformat, which is what "mechanical" has to mean for a commit that
touches this much of the crate.

* fix(scripts): make the root facade actually run on Windows

Adding the first gate that a contributor would run from the repository root
exposed two bugs in the facade, both of which made it silently wrong on the
platform this project is developed on.

1. Every npm and npx step failed. bin() appends `.cmd` on Windows, but Node
   refuses to spawn a .cmd or .bat with shell:false -- the CVE-2024-27980
   mitigation -- and fails with EINVAL and a *null* exit status. run.mjs only
   special-cased ENOENT, so the result was `FAILED: npx prettier --check .
   exited null` with nothing to explain it. check:client has three npm steps and
   has never been able to run here.

   Fixed by spawning only the npm shims through a shell. They are concatenated
   into a single command string rather than passed as an args array, because
   shell:true plus a separate array is deprecated (DEP0190) and prints a warning
   on every invocation; no argument in this file contains a space.

2. Every optional() step was skipped, always. onPath() shelled out to
   `where` on Windows, but where.exe lives in C:\WINDOWS\System32, which a Git
   Bash PATH does not necessarily contain -- on this machine PATH carries
   System32\Wbem, System32\WindowsPowerShell\v1.0 and System32\OpenSSH but not
   System32 itself. The probe could not start, `probe.status === 0` was false,
   and golangci-lint and sqlc reported as "not installed" while installed.

   Fixed by resolving against PATH and PATHEXT directly. No subprocess, and no
   dependency on which directories happen to be on PATH.

A spawn error other than ENOENT now reports its code instead of surfacing as a
null exit status.

Verified: before, `node scripts/run.mjs check:hygiene` died with "exited null"
and both optional steps printed SKIP with the tools present on PATH. After, the
same command runs prettier, shellcheck and actionlint and prints
"check:hygiene: passed", with no deprecation warning. `golangci-lint` is
detected by the new onPath where the old one missed it.

* chore(format): ignore build output that nested gitignores hide

Prettier honours the root .gitignore and no other. Every build and scratch
directory in this repository is ignored by a *nested* one -- Client/.gitignore,
.serena/.gitignore, .superpowers/sdd/.gitignore -- so none of them were
excluded from the new repository-wide gate.

The effect is not subtle. Running `cargo test` once drops roughly 850
formattable files into Client/src-tauri/target/, and the hygiene gate goes from
clean to "Code style issues found in 939 files". CI never sees it, because a
fresh checkout has no build output; every contributor sees it on their second
command.

Mirrors the three nested files rather than inventing a list: dist, coverage,
playwright-report, test-results, .vite, src-tauri/target and src-tauri/gen from
Client/.gitignore, plus .serena/ and .superpowers/sdd/. node_modules needs no
entry -- Prettier ignores it by default.

Verified: `npx prettier --check .` reports "All matched files use Prettier code
style" with a fully populated Client/src-tauri/target/ present on disk, and
still names README.md when a misformatted table is appended to it.

* chore(ci): shellcheck, actionlint, and a repository hygiene job

The last two gates RL-19 asks for. Neither existed: the shell scripts were
never linted, the workflows were never syntax-checked, and .githooks/pre-commit
carried hand-written `# shellcheck disable=` directives that nothing had ever
read.

New `hygiene` job, ubuntu-only and root-scoped, modelled on docs-consistency
for the same reason: every gate in it is platform-independent text analysis,
and .gitattributes pins eol=lf so a second OS would only re-prove line endings.
It runs `npm run check:hygiene` -- the same entry point a contributor runs, not
a parallel copy of the commands.

shellcheck ships in the runner image. actionlint does not, so it is pinned by
version and verified by sha256: an installer script piped from a branch would
be the one unverified download in a workflow file that pins every action by
commit SHA.

Prettier's step moves here from client-check, where it no longer belongs.

Both linters found real defects.

shellcheck, 3 findings in 8 scripts. Two are SC1125 errors in
.githooks/pre-commit: `# shellcheck disable=SC2086 - repo paths contain no
spaces` is not a valid directive. Trailing prose makes shellcheck discard the
rest of the line, so neither suppression was ever in effect -- and one of the
two was written earlier in this same branch, which is a fair demonstration of
why the gate is worth having. The prose moves to its own line above. The third
is SC2015 in start-server.sh, rewritten as an explicit if.

actionlint, 5 findings, all inside `run:` blocks it shellchecks once shellcheck
is on PATH. Three SC2015 in load-baseline.yml, rewritten as explicit ifs. Two
SC2035 in release.yml, where `sha256sum *` should not become `sha256sum ./*`:
the comment four lines above records that ParseChecksumFile exact-matches the
last field, so a "./" prefix would strand every deployed server exactly as a
"windows/" prefix would. `sha256sum -- *` satisfies the linter and leaves the
output bytes identical.

Verified all three gates in both directions with shellcheck 0.10.0 and
actionlint 1.7.7 on PATH. Passing: `node scripts/run.mjs check:hygiene` prints
"check:hygiene: passed" with all three steps run, not skipped. Failing:
appending `bait_fn() { cat $1; }` to Server/scripts/voice-test.sh fails on
SC2086; changing a runs-on to `ubunt-latest` fails on runner-label; appending a
misformatted table to README.md fails prettier. All three files restored and
confirmed clean afterwards. actionlint validates the new job in ci.yml itself.

* docs(plans): record B1 progress through B1-3

The header still read "B1-0 is complete; B1-1 is the next step" three merged
phases later. A plan that misstates where it is costs a reader the same
confusion whether it is stale by one phase or three.

B1-0 (#1410), B1-1 (#1411), B1-2 (#1412) and B1-3 (this branch) are done; B1-4,
dependency automation, is next.

Verified: `node scripts/check-doc-counts.mjs` still agrees on 27 claims across
9 watched documents -- this file is one of them -- and prettier reports it
clean.

* chore(ci): pin Repository Hygiene as a required check on dev

The second half of S-05. Its acceptance criterion is "tree is formatted AND a
fast required gate fails future drift" -- a check that runs but is not pinned
lets a formatting regression merge, so the gate is not a gate until this lands.

The name was read off PR #1414 with `gh pr checks` after the job reported
`pass` in 26s, not copied out of ci.yml. That order matters: the B0 script
records that three pinned names exist in no workflow file at all, and that a
required check which never reports blocks every PR forever.

Extends the existing script rather than adding a second one, per the B1 plan.

Also records, in the "deliberately NOT pinned" list, that Docs & Ledger
Consistency reports and passes on a dev PR yet is unpinned. That reads as an
oversight from the 2026-08-25 pass rather than a decision, but it belongs to
G-04, so it is documented here and not changed.

NOT APPLIED YET. Running this script now would pin a check that PR #1413 cannot
report -- its branch predates the hygiene job, so the job does not exist in its
workflow file and the check would never arrive. Run it after #1414 merges;
#1413 needs a rebase onto dev regardless.

Verified: shellcheck clean, the embedded JSON parses, and `check:hygiene`
passes with prettier, shellcheck and actionlint all running.

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
channels-members-dms.md Channel list/switch/categories, member list + presence + typing, roles, DM open/close, blocking
voice-and-e2ee.md Voice join/leave, mute/deafen/camera/screenshare, push-to-talk, active-speaker, and the E2EE securing/key-ready indicators
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_leave / 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_speakers voice.* Voice roster + speaking rings
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.
