- A13: with Plex off, the Home shelf and the hero's comfort tier go YouTube-only like the rails
beside them (owner's call: hide the tiles). The pins are kept; GET /pins still lists them.
- Reorder deals the listed pins into the slots they already hold, so a partial list (hidden Plex
pins, a stale tab) no longer puts two pins on one position; repeats are ignored.
- A21: a comfort hero carries `pinned_from`, the shelf entry it was resolved from; its menu acts on
that pin, so a pinned show's next episode offers "Unpin" instead of creating a second pin.
- B12: the palette's "Meglepetés" asks for the surprise tier (the next press leading with it); the
rotation carries on from there.
- B13: the surprise token names the history entry it was requested for (minted by setPage's new
`then`, after the push) and is dropped on any other entry, so a navigation that never mounted
Home cannot replay it later.
- During a budget switch the rail shows the previous budget's payload
(keepPreviousData) while the new key is empty; the move read that empty
cache, found no tile and silently did nothing. It now acts on the order
the rail rendered.
- A refused move was undone only by a re-read; when that read failed too,
the shelf kept showing the order the user had just been told was not
saved. Moves are now written one at a time (the move rows wait, with a
"saving" note), which makes restoring the shown order correct — the
overlapping-moves problem that ruled a rollback out cannot occur.
The second half of the pending-button sweep: where the pressed control does
not merely disable but LEAVES the page — an invite row gone after Approve,
the inbox's Clear all gone with the last notification, a section gone once
its last row is handled — the browser dropped the focus to <body> and the
next Tab started over at the top.
useFocusKeeper, on the page scroller: when the element holding the focus is
removed and the focus fell to <body>, the first focusable thing in its slot
takes it (what followed, else what preceded, else the nearest ancestor still
on the page). Portaled layers (menus, dialogs) sit outside the scroller and
return focus themselves; listNav's keyboard lists are left alone — their `j`
already goes on from the slot, and a row scrolled out of a virtualized list
must not drag the focus after it.
A focused button that turns natively disabled loses the focus to <body> in
Chrome. The app disables the very button that was pressed on ~60 sites — a
mutation pending, a pager at its last page, undo with nothing left, a player
at the end of its queue, a form gone clean — so a keyboard user was thrown
out of the page on every such press.
One primitive instead of a fix per site: ui/FocusSafeButton renders a
focused-and-disabled (or busy) button as aria-disabled with a click guard,
and applies the native attribute again once the focus is elsewhere. It asks
the document at render time as well as listening for focus events, because
a window without focus fires none (measured). ui/Button and ui/form's Switch
are built on it; 57 hand-rolled buttons swapped their tag for it keeping
their classes, and three hand-copies of the rule (the channel page's Block
and Hide, ChannelDiscovery's Subscribe) now pass `busy`. The soft state's
dim look is one rule in index.css.
`local/focus-safe-disabled` refuses a new raw <button disabled>, pinned by
focusSafe.contract.test.ts. lib/plexDetailUi moved to components/: it is
components, and lib may not import the primitive.
Measured on localdev in Chrome: the audit log's Next button keeps the focus
on reaching the last page, reads aria-disabled, and the guarded click does
nothing.
The reason for a disabled menu row lived in a `title` on a natively disabled
button: no pointer events, so no tooltip, and roving focus skips the row —
four translated sentences reached nobody (the Watch later rename/delete
lock, "no other list to move to", the reorder gate). An aria-disabled row was
tried and reverted in E10's review. ActionMenu items now take a `note`,
rendered as a muted line under a disabled row's label: seen, and readable in
a screen reader's browse mode. Only the icon and label dim — row-level
opacity would dim the explanation too. The reorder group states its reason
once, under its first row.
The pxBox contract test held the literal w-[150px] it probes, which the new
lint rule refuses, and stickyTop's test used Array.at, outside the tsconfig
lib. Both landed because a local lane check piped its exit code into tail.
- "A page with a sticky ColumnHead must declare fadeTop: false" lived in
prose: a registry flag on three pages plus an App special case for the
Channels card layout, and the next table page would have re-acquired the
fade-on-the-header defect with every lane green. ColumnHead now registers
itself with the enclosing PageScroller (ui/stickyTop) while mounted; the
registry flag, the App branch and the prop plumbing are gone. Measured on
localdev: the top mask is 0px under Channels' and Audit's headers, 20px on
Home and the Feed.
- ui/DataTable mounted its table AND its card list at every width, one
hidden by CSS: double DOM and render cost, duplicate ids, two keyboard
copies of every row. It now mounts the one the `md` media query calls for
(lib/useMediaQuery); the keyboard test asserts one layout at each width.
- The Plex module's content width went px → rem with the rest of the page.
- PriorityStepper labelled itself with channels.row.* and told every caller
it orders the Feed; Combobox said plex.loading / plex.filter.moreRefine /
sidebar.match on the feed sidebar. The generic strings moved to common.*,
and what a priority MEANS arrives as the stepper's `hint` prop.
uiI18n.contract.test.ts pins components/ui/ to the platform namespaces —
the import boundary could never see an i18n key.
- 32 px-frozen box utilities (w-[150px], max-w-[1600px], left-[18px], …)
became spacing-scale steps (w-37.5, max-w-400, left-4.5): identical at the
default text size, and now they grow with the Settings slider instead of
clipping or re-wrapping their own labels. An eslint rule refuses the px
form beside the older text-[Npx] one, pinned by pxBox.contract.test.ts;
measured in the browser that every new step is generated at its old px.
- chipLane's import-strip regex ran past a side-effect import into the next
statement's `from`, hiding a lane between them; it now stops at the
import's own `;`.
- Home's rail handed each card a fresh `() => menu.triggerProps(c)` per
render, defeating memo(VideoCard) on every tile whenever the menu's own
state changed. `useItemTriggers` (ui/useContextMenu) keeps one trigger per
item, index-aligned; tested for identity across renders.
- The Button accessible-name union had one hole: `<Button icon={…} />` with
no children and no size typechecked into a nameless button. A textful
button now needs children or a name; pinned with @ts-expect-error.
- comfortPin's header said the pin belongs "on every card and row", which
the code never meant (an episode, a season, a person are not pin kinds).
It now says what is pinnable — and the show page's Related strip, whose
shows ARE pinnable, gets the pin menu it was missing (and a rem width).
- gridColumns / feedView / VirtualGrid claimed layouts 1024–2560 are
"byte-identical" under the column cap; the small cards are capped at 2560
with the filter rail collapsed. The comments say so.
~150 HTTPExceptions carried a hand-written English sentence as their detail,
shown verbatim under the Hungarian UI — in the blocking error dialog and on
every inline surface that printed HttpError.detail (sign-in, setup wizard,
change password, the passphrase gate, live search). Four also quoted an
upstream exception's text back to the user.
- app/refusal.py: `refused(status, reason, **params)` → {code: "refused",
reason, …params}; localizeDetail translates errors.refused.<reason> with the
params interpolated. "Unknown X" 404s use the existing not_found(what).
- sysconfig.set_value raises InvalidSetting (reason + bounds) instead of an
English ValueError; the three writers answer it through setting_refused.
- The Plex connection/write/image failures log what the upstream said and
answer a reason; the search scraper's failure is logged and answered as
youtube/unavailable (it crashed refusal_reason before).
- HttpError.detail now only ever holds a translated reason: a string detail
(only the framework's own can remain) is left out, so reading .detail is
safe everywhere — including destructured, the hole the raw-detail source
scan could not see. That scan and its five-file exception list are gone.
- Enforced: test_http_details.py fails on any HTTPException with a sentence
for a detail; the contract test requires every refused reason and every
not_found "what" in both languages, and no key for one that is gone.
- local/jsx-comment-text: a // inside JSX children renders as text; the rule
is ten lines in eslint.config.js rather than eslint-plugin-react's ~1800
lockfile lines.
HLS sessions were keyed by the item, so a second account opening the same
film killed the first one's session; the displaced player reclaimed at its
playhead and evicted the other in turn. The registry is now keyed by
(viewer, rating_key), segment requests resolve by both, and the session
directory carries the viewer (the orphan sweep still recognises the older
shapes).
Only transcodes counted toward a cap, so remuxes — each a whole segmented
copy of the film on the scratch volume — were bounded by the library size.
Three bounds now apply after every start, each dropping the least recently
used: two sessions per account, the transcode cap, and a new admin knob,
plex_max_sessions (default 8), over every session. A superseded session
request returns at once, since it waits on the killed ffmpeg, so an account
cannot park more request workers than it may hold sessions.
The subtitle extractor's full-pass slots were global and minutes long each;
one account opening subtitles on film after film could hold them all. An
account may now hold three of the six, and still gets windows past that.
A full pass that ran out of time kept what it reached, but its retry an hour
later started again at 0, so a file too big to read inside the extraction
timeout never completed. The pass now starts where every embedded track's
coverage from the head ends (less the window pre-roll, so a cue across the
join is read whole). The seek needs -avoid_negative_ts on this read as on a
window, measured on a real file: without it the cue running at the start
shifts the whole output.
A partial track whose full pass had failed never reached a settled state, so
the player polled it every 2 s for the rest of the film. The status now says
whether the track is still growing, and a stalled one is polled every 15 s —
still inside the 60 s lookahead that reads the next window before an edge.
move_item checked "already in the target?" and then re-parented without a
lock, so a second tab's add or the scheduler's YouTube merge committing the
same video in between hit uq_playlist_video and answered a raw 500. The
re-parent now runs in a savepoint and a conflict falls back to the
already-present outcome. The target is touched only when the row landed in
it (an untouched list was promoted in the rail's "recently changed" sort),
and _touch stamps the database clock like the mixin's own onupdate.
The canonical-patterns table names owned_or_404 against ad-hoc ownership
helpers; six were left (_own_playlist, _own_playlist_or_404, _own_view,
_own_tag, notifications._owned, downloads._own_job), two of them
hand-rolled with a bare English 404. All call sites now use owned_or_404,
and the download/link/notification 404s are structured like the rest. The
contract test reads every "what is gone" the routes name, and the YouTube
refusal reasons, and requires both languages to name each.
The rollback of a refused watched mark guarded against Plex's REPORTED
duration. On a file shorter than its metadata the end sits outside the
finish margin, so playing to the end and having the mark refused stored the
very end as a resume point on an unwatched row: a ~99% bar that reopened in
the last seconds. The media's own ended flag now decides.
The two manual syncs (subscriptions import, playlist pull) had no YouTubeError
handler, so a quota, token or transport failure was a raw 500 and the blocking
"Server error" dialog (E9 F1). The other YouTube routes answered either the
upstream's English or a playlist-scoped "youtube_failed".
One helper, routes/_common.youtube_refusal: 422 {code: "youtube", reason} with
the reason sorted by what the user can do — quota (wait for the reset),
reconnect (the token step refused), unavailable (retry). Used by every route
that surfaces a YouTube failure; localizeDetail translates it.
"Reconnect" had no path: a grant Google revoked still read as granted, so
Settings and the wizard offered no connect button while every call failed.
An invalid_grant from the token endpoint now clears the stored grant.
The card menu's reset read 'Clear watch progress' but also un-hides and un-watches; it now says so.
The resettable rule, the demo-first role key and the display-name fallback each lived in several
components tied by comments; they are shared helpers now, and the menu reuses the card's own
strings instead of duplicate keys.
The query read the typing-debounced search, so for 300 ms after a jump it mixed the new view's
filters with the old view's text and fetched rows neither view shows. useDebounced takes a settle key
whose change applies the value immediately.
Restoring by name picked the first item of that name, so Back on the log console (repeated
http.request lines) or two same-titled downloads landed on the wrong one. The saved place wins while
it still holds the name; otherwise the nearest item of that name.
The server now logs polled reads at DEBUG, and the browser's copy of each
request line promises the server's level: at INFO the unread-count polls
filled My log within minutes and, at Detailed, the shipped log. The server
marks a line it logged at DEBUG with X-Log-Quiet, so the polled-route list
stays in one place.
The countdown's clock was the moment Settings mounted, so a level raised
two minutes after opening the page read "24 h 2 m" until the first tick
(measured on prod). The clock is read at render; the interval only
re-renders.
The Feed's chips + Sort + View row did not fit one line at 375px and pushed
the page 21px wide; the toast stack capped its width by the viewport while
it sits right of the sidebar. The toolbar rows (Feed, Plex browse) wrap,
and the toasts are capped by their host.
Settings → Account names the latest sign-in on any device (only the
admin's user list did, though the 0.88 notes said otherwise), and the role
in the reader's language instead of the raw `user`.
Right-click, long-press or Shift+F10 on a feed card offered only the
comfort-shelf pin; watched, saved, hidden and the progress reset were
reachable only by hovering or Tabbing through every card.
Signed out, the tab read Home's question over the sign-in form; the legal
pages read just "Siftlode". The download field asked only for a YouTube
link although Facebook and the rest download too.
Opening a card left Home, and Back came back to "Doesn't matter" with a
different hero, whose card then dropped out of the Continue rail and moved
the keyboard onto its neighbour. The budget, reroll seed and seen list live
on the history entry now, and a returning list focuses the item by its
name before its place.
Every filter change replaced the history entry, so Back after a request or
job pivot left the console altogether (the 0.90 notes promised otherwise).
A pivot follows a link and is its own entry now; the console reads the
landed entry back on popstate. The other filters still adjust in place.
A tab left open across a release asked for a lazy chunk the server no
longer has (prod: DownloadDialog 404 an hour after 0.89) and fell to the
crash screen. `vite:preloadError` now reloads the tab once a minute at
most; a second failure is let through to the error boundary, which now
wraps every entry — the public /watch, /privacy and /terms pages crashed
to a blank page.
YouTube's RSS goes dark per channel for hours (prod 2026-09-18/19: 393 of
396 feeds answered 404 for four hours, sticky per channel, so a retry does
not help), and nothing else read a followed channel's new uploads. A
channel whose feed has not answered for `rss_fallback_hours` (admin knob,
default 2, 0 = off) now gets one page of its uploads playlist through the
Data API (1 unit), at most once per window, yielding to the backfill
reserve. Spend is attributed to its own quota action.
- "Load older" is not offered off a loading filter's placeholder rows,
whose cursor belongs to the previous filter.
- A failed older page, stale rows and missing counts each get their own
message (HU/EN).
- Live shows as off once a failed read stopped the polling; pressing it
again reads now.
- Live stops polling on a failed read and marks the list as possibly
stale (with Retry), instead of re-raising the error dialog every tick.
- While live, a refetch reads the newest page only, whatever the cache
holds (a late "Load older", a revisited filter set).
- Copy is disabled and the list dimmed while a filter change loads.
- Dates follow the UI language; the pivot chip uses the shared .chip.
- Tests: query-string wire test, Copy, every facet's skip key.
Both log viewers put their lines in a NavGrid: j/k (and the arrows) step
from line to line, and Enter opens one exactly as a click does (the line's
button is its `data-nav-open`). A focused line is named by its code and
message.
The console's nav entry is "Szervernapló" / "Server log", its page title:
"Diagnosztika" was already the Settings tab that holds the user's own log,
and two places with one name read as one place.
Admin → Diagnostics reads the server's stored log: one list, newest first,
where a line opens in place to its full record (time, source and logger,
account, request and job ids, version, message, attributes, stack). A
request or job id narrows the list to that request or job with every other
filter off, shown as a removable chip. Filters: level group, source,
account, event, period and a free-text search; all of them live in the URL
(`l*` keys, which setPage clears like the Plex and Channels keys), so a
filtered view is a link and Back restores it. "Live" re-reads the newest
page every few seconds while the tab is visible; paging into older rows
turns it off. Copy puts the loaded lines on the clipboard as JSON lines.
The facet counts now honour every filter but their own, as the feed's do:
a request pivot narrows them, and a picked level does not zero its
siblings. A value in use stays offered even when the counts drop it.
"Saját napló" and the console draw a line with one shared component,
`LogLine`, whose phone layout gives the message its own full-width line
(sharing the code's line left it a few characters). The level groups
moved to lib/log.ts for both.
The console's own reads are logged at DEBUG on success, like the
healthcheck: at INFO its live tail filled the log with itself.
E22 (activity trail): a consented, self-expiring diagnostics level with the user's own log visible
before anything is sent, last sign-in, bilingual privacy policy and terms, an admin diagnostics
section, and pickers for every closed-set setting. Plus what the epic's measurements turned up on
the way: doubled chat delivery, Settings on a phone, locale-ignoring dates and numbers, and the
feed poll narrowed to followed channels.
Three round-1 fixes whose tests passed against the broken version too.
The focus restore keeps watching until the element that closed the box is GONE, rather than spending
itself on the first render after the change — the distinction Chrome exposed and jsdom did not,
because jsdom commits the save in one render where Chrome takes two. Driven now through the general
case instead: the user moved the focus elsewhere while the request was out, renders keep coming
while that element is still there, and the restore happens only once it disappears.
The choice test's i18n mock returned an option's bare value, which is exactly what dropping the
`config.choices.*` lookup renders — a Hungarian admin would have seen `on`/`off` instead of
`GPU`/`Szoftver` with the gate green. Marked labels now, still short enough not to move the
segmented-bar budget the same file measures.
The admin config row's stacking had no test at all, only its sibling fix did — and stacking is the
only fix for a text or number key, whose fixed-width input is the wide control. Class contract, as
SearchBar.dom.test.tsx already does for the narrow-header rules, since jsdom does no layout.
Also: the time-zone cleanup deleted TZ, and Node re-reads it on assignment only, so the process kept
the last zone the file set. Harmless until someone appends a test below it.
Picking "Alap" revokes the consent, and a batch still in flight is then answered by the server with
the same 409 a real expiry gets. The 409 arm only checked that the consent session had not changed,
not that this tab was still streaming — so the user's own log gained a "diagnostics level lapsed"
line for a level they had just turned off themselves, plus a pointless `me` refetch. The same guard
also stops a lapse this tab has already announced being announced a second time.
Measured in Chrome by holding the POST at the network layer, switching to Alap and only then
answering 409: the line appears without the guard and not with it.
Three tests that named the session counter never reached it — they settled the refusal while the
stream was already stopped, where `unsubscribe` does the work, so the counter could be deleted from
both arms with the suite green. The refusal now settles after the re-raise, which is the ordering it
exists for. Same for the queue trim on the 429 path: the old test unshifted a batch into an empty
queue, so the trim was a no-op and only the subscribe path was ever measured.
formatDate read a date-only value as UTC midnight and showed it in the viewer's zone, so the legal pages' last update read a day early west of UTC. Date-only values are shown in UTC. The legal pages' hand-rolled language buttons are the landing page's LanguageSwitcher. formatDateTime and formatDate get the two-language test formatNumber already had.
A segmented bar cannot shrink or wrap, and the five log levels (~300 px) are wider than a phone leaves beside the navigation rail. A choice is a bar only when its labels are short; the rows stack below sm.
Deep-review round 1 of E22.
- After a 429 the stream sent one POST per new event while a full batch
waited; it now stays quiet for 15 s. Past the queue cap the oldest
events go, as the comment always said, a refused batch included.
- A batch refused after the level was lowered came back into the queue
of a later consent in the same tab; each consent is its own session.
- A `me` fetch that left before a level or preference change could put the
old value back for up to a minute. `updateMeCache` writes the cache and
cancels that fetch; usePref goes through it too.
- The consent box's buttons and "revert now" took the focus with them to
<body>; it returns to the level picker. Watched until the button is
gone — in Chrome the saved level arrives in two renders, and a one-shot
check spent itself on the first (jsdom never showed it).
- The countdown line is no longer a live region re-read every minute.
- "Saját napló" rows were keyed by index on a newest-first list, so every
new event remounted every row and dropped the focus off a row button.
- Home tests mocked the api without downloadIndex, so every card's download button logged a
missing-queryFn error (64 stderr blocks per run).
- QueryState rendered without an i18n instance; Modal.fullscreen awaited a synchronous act,
which React reports as an act environment it does not support.
- pytest: Starlette 1.x's TestClient is built on httpx2 and warned on every run without it
(pinned in requirements-dev); alembic.ini declares its path separator.
The 43 react-refresh/only-export-components warnings the gate let through meant an edit to a
provider (or AnchoredPopover, Toaster, plexDetailUi, …) could not be hot-swapped: Fast Refresh
reloads a module that also exports hooks or helpers.
- Each provider's contexts, the types its hooks return and the hooks themselves live in a sibling
context module (navigationContext.ts, channelsContext.ts, …); the provider file keeps the
component. loadAccountFilters moved next to the feed filters' defaults (feedFiltersInit.ts),
following navigationInit/playlistsInit.
- Helpers that sat in component files have their own modules: welcomeMode, downloadTitle,
plexPlayable, channelSync, ui/anchoredPopoverHooks, ui/pageToolbarSlot, ui/pagerContent,
ui/toastLevels, ui/overlayOrder, ui/tableAlign, lib/plexDetail; the cells of the channel columns
and the registry's page wrappers are components files of their own (channelCells, modulePages).
- usePersistedTab, an alias of useAccountPersistedState, is gone; its callers use the original.
npm run lint is now eslint --max-warnings 0, so a warning fails the gate like an error does.
The 12 react-hooks/exhaustive-deps warnings the gate let through:
- ShareDialog and YearFilter built a fresh [] per render while their query loaded, so their
memos recomputed on every render; they share one empty list now.
- VideoEditor's drag effect called a seek/moveBoundary recreated each render; both are stable
callbacks in its deps.
- WizardProvider re-checks onboarding on exactly the fields it reads (not the me object, whose
60 s refetch would reopen a closed wizard).
- Channels, Feed and PlexPlayer list the stable values they already used.
- The player's keydown effect is bound once on purpose (its helpers read refs): said so, with a
disable, as the codebase's other deliberate sites do.
- dialogFocus and the YouTube player's cleanup read refs React may already have let go of; they
use what they captured when the effect ran.
A user can raise their diagnostics level to Részletes (DEBUG) or Teljes (TRACE) for 24 hours from a
new Settings tab, after a consent box that says what is recorded, that the server keeps it and for
how long (the instance's own retention), and that it lapses. Alap is the base and needs no consent.
- users.diagnostics_level/_until (migration 0087), written only by PUT /api/me/diagnostics, which
computes the expiry itself; the demo account cannot raise it. /api/me reports the level in force.
- The server logs an elevated user's requests at that level and stores every line of them
(logs.LevelGate on the stdout handler and the sink; the root is lowered only while an elevation
is active). Teljes adds the redacted query string to the request line.
- POST /api/diagnostics/events stores the browser's log as source=web rows: account from the
session, body capped while streaming, events/attrs capped, re-redacted, events under the
consented level dropped, timestamps clamped, 30 batches a minute, 409 once the level lapsed.
- lib/diagnostics.ts applies the level to the tab and streams only what happens after consent, in
batches, never its own request lines, with a keepalive flush on pagehide; stops on lapse (its
own timer), on withdrawal and on 409.
- Detail hooks at DEBUG: which control was clicked (test id, icon, app copy in English — never user
text, input values or a link's query), visibility/bfcache/resize, filter changes
(lib/filterLog.ts; typed search only at TRACE), player events (lib/mediaLog.ts; media errors are
warnings at every level). Offline/online at the base level.
- "Saját napló" viewer: live, newest first, level groups with counts, search, row details, copy
the filtered events as JSON lines, clear.
- Privacy policy and Terms exist in Hungarian and English (a contract test holds both languages to
the same sections); the policy now describes the server logs and diagnostic logging, self-service
deletion and password sign-in.
Fixed on the way:
- A sync auth dependency ran logs.set_user on a copied context, so the account never reached a
handler's own log lines (measured); a per-request mutable scope carries it now.
- The Settings tab rail left a phone no room (clipped labels, buttons over text): below `sm` it is
a scrolling row above the content.
- PUT /api/me/preferences took a bare dict body; it is a Pydantic model now.
The browser now keeps its half of the one event shape logs.py defines:
lib/log.ts is a levelled, redacted, bounded (2000 events) in-memory ring
with the server's level names and severity numbers. Nothing leaves the
browser yet; sending is the consented diagnostics level (S5).
- lib/http.ts `send` is the one fetch: every request carries an
X-Request-Id and becomes one http.request event. The server echoes the
matched route template in X-Route (only for a matched route, so a raw
path with a value in it is never sent back); without one the client
templates the path itself. req, beacon, the upload XHR, the public
watch page and the legal pages all go through it.
- Hooks: app start snapshot, uncaught errors and rejections, History
push/replace/popstate (a scroll-only replace is not an event; parameter
values only at DEBUG, typed search only at TRACE), notifications, the
error dialog, the crash boundary, failed queries and mutations (key
head only), and the messages socket (lifecycle, frame types at DEBUG).
- Redaction is one contract: backend/tests/fixtures/log_redaction_cases.json
runs against both redact() implementations.
- Lint: fetch, XMLHttpRequest and WebSocket each belong to one logging
module, console to none; a contract test proves the rules fire.
Fixes a socket takeover: the close of a socket released by the last
subscriber cleared the newer socket a quick re-subscribe had opened and
scheduled a third, leaving two live sockets that delivered every message
twice (measured in Chromium: 3 created / 2 live before, 2 / 1 after).
