Dmitry VerkhoturovandGitHub 4793c1cd2c Fill the instance URL into the embedded frontend at serve time, and stop pinning compressor output in tests (#2198)
* Assert what the image endpoints promise rather than the compressor's output

Three tests pinned the exact bytes or the exact length of an encoded
image, so they fail on any toolchain whose deflate or png encoder emits
something different. CI pins go 1.25 and passes; go 1.27 fails all three,
while the images themselves are perfectly valid.

TestRest_QR now decodes both the golden file and the response and
compares the pixels, which is the same assertion about the qr code and
none about the encoder. The two resize cases assert the decoded image
fits the box resize was given and touches one of its sides, which is what
fitting to a box means and what the function actually promises.

Resolves #2200.

* Fill the instance URL into the embedded frontend at serve time

The widget falls back to a compiled-in URL whenever a page omits
`remark_config.host`. The bundler cannot know that URL, so it emits
`{% REMARK_URL %}` and each distribution substitutes it: the docker image
rewrites the files under its web root at container start, and the release
binary, which serves the build embedded in itself, had nothing doing it.
`prepare-release-assets.sh` filled the marker with `http://127.0.0.1:8080`
before the embed instead, so every copy of the binary shipped pointing at
the visitor's own loopback address, and on an https site the request is
blocked as mixed content besides.

It has been that way since v1.11.0, the first release to embed the
frontend, and the earlier binaries embedded none, so the tarball has never
served a correctly addressed widget.

The placeholder now survives into the embedded copy and the file server
fills it with the configured `REMARK_URL` as it serves, which is what the
docker image already does to its own copy. The image no longer bakes the
loopback address into its embedded copy either, so the fallback it keeps
for a missing web root is correct rather than misleading.

Substituted in html, js and mjs, the same set `docker-init.sh` rewrites,
and the served size is the substituted one so a response is neither
truncated nor left hanging.

Nothing exercised the marker the frontend build emits wherever the instance
url belongs. Every page in the suite sets `remark_config.host` from its own
origin, so the compiled-in fallback is never read, and a distribution that
stopped substituting would keep the suite green.

Two tests. The first reads the served bundles and pages back and asserts the
marker is gone from each and that what replaced it is this instance. The
second covers what the substitution is for: the widget document carries no
host of its own, since `iframe.html` builds its config from a query string the
parent never puts one in, so everything it requests is addressed with the
compiled-in url. It asserts the widget renders and that the config request
went to this instance.

The demo pages cannot show the second. Their loader builds the bundle's own
script url from `remark_config.host`, so a page without one never gets as far
as loading the widget.

Verified by disabling both substitution paths, the serve-time one and the
docker image's, and rebuilding: both tests fail. Editing the files on disk is
not enough, since the file server substitutes as it serves.

The served body now depends on remarkURL, but cacheControl builds its
etag from version and path only. An operator who notices the widget is
addressed to the wrong host, corrects REMARK_URL and restarts the same
binary gets 304 on revalidation, so the client keeps a bundle pointing
at the old host. Cache-Control is no-cache, so it revalidates every time
and never ages out of that state either.

That is the exact situation this substitution exists to fix, so the
validator has to carry the url.

Dmitry VerkhoturovandGitHub 23be25d84a Fix seven widget defects, including the cookies the separate-domain setup needs (#2197)
* Drop the frontend workspace root and re-resolve the lockfile

`frontend/` carried a `package.json`, a `pnpm-workspace.yaml` and the lockfile
for a workspace of exactly one package. Two manifests meant two places to
declare a version, and the app pin was the one that did not win: `preact` and
`@babel/core` were each written twice, and a bump to the app manifest alone
would have been a silent no-op, since `pnpm.overrides` decides and it lived at
the root.

Everything pnpm reads now lives in `frontend/apps/remark42`: dependencies,
`packageManager`, `engines` and the overrides. `frontend/` keeps `.nvmrc`,
`.husky` and `CLAUDE.md`, none of which pnpm reads. The directory nesting
stays: every path in the repository points at `frontend/apps/remark42`,
including the published contributing docs, so moving the package up would have
rewritten 14 files to no benefit.

Moving the manifest kept the old resolutions verbatim, which left optional peer
subtrees the tree no longer reaches: `ts-node` under jest, `@swc/core` under
webpack, `vitest` under `@testing-library/jest-dom`, `tslib` under
`webpack-dev-server`. None is referenced by any config or source file here.
Re-resolving drops 137 packages and moves 59 to versions already permitted by
the ranges in the manifest, 1446 to 1308, with no direct dependency changing
version: the five that look changed differ only in their peer suffix. Every
file `pnpm build` produces is identical in size before and after.

The frontend-deps stage of the Dockerfile sets `CI=true` so the `prepare`
script skips husky, which has no git repository to install hooks into there.

* Stop markdown-only changes triggering heavy workflows, and check the documented versions

`ci-backend.yml`, `ci-build.yml` and `ci-frontend.yml` all end their path
filters with `!**.md`. The e2e workflow did not, so a change to any markdown
file under `frontend/` or `backend/` matched its `frontend/**` and `backend/**`
entries and started a docker build and the whole browser suite. The release
filter had the same hole and two of its own: it names `README.md` and `LICENSE`
on purpose, since `.goreleaser.yml` packages both, so it now excludes markdown
under `backend/` and `frontend/` only. `CLAUDE.md` and the installation page
were listed as well, and neither is packaged.

`ci-site.yml` goes on matching markdown, which is right, since the site is
built from it. It excludes `CLAUDE.md`, so a future `site/CLAUDE.md` cannot
start a site build, and `site/README.md`, which documents how to build the site
rather than being part of it.

The installation page tells a reader that a source build needs Go 1.25, Node
24+ and PNPM 10. Nothing kept those in step with `backend/go.mod`,
`engines.node`, `packageManager` and `.nvmrc`, and the drift is silent: a wrong
version in the docs builds and tests exactly as well as a right one. `.nvmrc`
is the pin with form here, having sat at 16 through the whole node 20 migration
because nothing red ever pointed at it. The check compares each stated version
against its source and holds `.nvmrc` to `engines.node`, and it fails when the
page states no version at all, so removing the claims cannot turn it into a
check that passes by comparing nothing.

Its own workflow rather than a step in an existing one, since the inputs span
the backend module, the frontend manifest and the site.

* Fix the cookie fallback page, asset path, message senders, auth teardown and cookies

Two defects with the same origin: 5825a55b, the January 2021 frontend
rewrite, first released in v1.7.0.

It removed the build entry for comments.html while leaving both the
template and the link to it in place, so the page the auth panel offers
when third-party cookies are blocked has been a 404 ever since, for
exactly the reader who has no other way in. The template needed no
changes; it is built again, and an e2e case now opens it on a thread
carrying a comment and waits for that comment, so the page being served,
its inline script running and it asking for the thread named in its own
query string are all covered. Against an image built without the plugin
entry that case fails on the 404, which is the regression it exists for.

It also fixed the public path to the domain root, so an instance mounted
under a prefix, which manuals/separate-domain documents, asked for
/web/google.svg when its own icons live under that prefix. Fifteen
provider icons in remark.mjs and one in last-comments.mjs. The path is
now derived from the url the bundle was loaded from, which is correct for
both arrangements, and the file loader no longer overrides it.

The host page also accepted postMessage from any window: every frame on a
page can reach window.parent, and the handler resizes the widget, scrolls
the page and opens the profile overlay. It now ignores anything that did
not come from a frame this module created.

A fourth, in the same family: the OAuth flow never tore its polling down.
`subscribed` was declared, checked and cleared but never set, so the guard
against a second subscription was dead code and every provider click
attached another listener pair. The five minute deadline then rejected
without unsubscribing, leaving those listeners and a retry that
reschedules itself for as long as getUser returns null. Cross-domain is
where getUser never stops returning null, so a reader on the arrangement
manuals/separate-domain documents was left polling /auth/user once a
minute for the life of the page, against a route capped at 2 req/s. It
also rejected with no argument, and the caller stores that as the error
state, so the interface had undefined to render. The deadline now tears
the subscription down and rejects with an error.

The message check had a second half. Hardening the parent left the widget
document trusting any sender, and it acts on signout and theme, so
anything holding a reference to the frame could sign a reader out.
`auth.hooks` already checked `event.source !== window.parent`; that check
is now a shared `isFromParent` and the three listeners that lacked it use
it too. The origin cannot stand in for it, since the host page is
whatever site embeds the widget and `ALLOWED_HOSTS` is enforced server
side through `frame-ancestors`.

And createInstance stacked its listeners. It reuses the marked iframe
instead of building one, but installed three listeners plus a title
observer on every call, while destroy could only reach the newest
closure, so a second call without a destroy stranded a set for good. The
listeners of the current instance are now detached before the next set
goes on. Reuse and the ignored config are unchanged: that contract is
open in the backlog note and not settled here.

The auth cookies the embedded case needs were not being delivered, in
both halves of the client's own writer. The name was decorated:
setAuthCookie prefixed with __Host- whenever the page was https, so a
real deployment wrote __Host-JWT and __Host-XSRF-TOKEN while the backend
looks for JWT and the fetcher reads XSRF-TOKEN, and nothing anywhere
reads a prefixed name. Nothing caught it because the prefix is applied
from the page protocol and every test and the dev server run on http;
there is now a second suite pinned to an https page, which is the only
condition that shows it. And the attributes could not be delivered: both
were SameSite=Strict, judged against the top-level site and not the
request's own origin, so a Strict cookie is never sent from a
third-party frame, which is the entire configuration this code exists
for. They now follow the embedding, Strict while the widget shares its
page origin and None with Secure and Partitioned once it does not, since
that is the only third-party form browsers still accept. Over http in a
third-party frame no combination works, and the strict form is written
instead of one the browser would reject outright.

That leaves the client half of #1877 working, whose reporter wanted
AUTH_SEND_JWT_HEADER for exactly this arrangement, and whose first half
merged as #1929. The server's own cookies still carry no Partitioned;
that is upstream work in go-pkgz/auth.

Two plan changes. A review pass corrected its central Path B premise,
which said the first document render is anonymous permanently, in every
configuration: it is anonymous in the configuration remark42 ships,
go-pkgz/auth exposing XSRFIgnoreMethods and remark42 leaving it unset.
The door is not shut, it is closed by a setting, and opening it is
scoped security work and not a flag flip, because GET /deleteme
deletes every comment a user has written and is a GET so the emailed
link works. And the separate-domain arrangement is promoted from a
constraint bullet to a named requirement with acceptance criteria, since
a test that signs in and posts without reloading passes while
persistence is entirely broken.

Review found a seventh, and it was reachable only because of the first:
comments.ejs built its title with innerHTML from the url query
parameter, so restoring the build entry made a reflected XSS live on the
instance origin, where the page is a top-level document, frame-ancestors
does not apply and the /web CSP allows unsafe-inline. The anchor is now
built through the DOM with textContent, and only http and https reach
href, since escaping alone leaves a javascript: url working. Two e2e
subtests pin both halves, and mutation testing separates them: restoring
innerHTML fails four assertions, while keeping the escaping and dropping
only the scheme guard fails the href one alone.

Review also found the poll teardown test did not exercise the poll.
handleWindowVisibilityChange is reachable only from the two listeners
and from the retry it schedules itself, and the test dispatched neither,
so no request was ever made and the assertion compared zero to zero; it
passed with the teardown reverted. It now dispatches focus, asserts
requests are being made and keep coming, and only then that they stop.
And the teardown could not cancel an in-flight getUser: a null resolving
after the deadline ran the code past the await and scheduled a fresh
retry with nothing left to clear it. A closure-local flag checked after
the await stops that, chosen over a second guard at the top of the
handler because only one of the two is detectable by mutation and this
is the one that prevents the stray timer rather than neutering it.

The inline handler in the iframe template accepted messages from any
window while acting on them through location.replace and document.title.
It now takes only the parent, the same check the host page side makes.

Dmitry VerkhoturovandGitHub 0b651dddd4 Make backend tests wait on conditions instead of durations (#2190)
* Make backend tests wait on conditions instead of durations

The backend workflow has a long tail of runs that fail once and pass on
a rerun. Every one of them comes down to a test assuming an operation
finishes within some duration rather than waiting for the state it
needs. Three were reproducible and each was reproduced against the old
code before being changed: TestServerAuthHooks minted a token that lived
one second and never tested expiry, so a slow runner turned the first
POST into a 401; TestServerApp_AnonMode saw "connection refused" because
waitForHTTPServerStart returned silently after three seconds and left a
later assertion to fail with something unrelated; TestFsStore_Cleanup
slept 200ms against a 300ms ttl that Cleanup widens to 400ms with its
commit grace, so roughly 100ms of stall collected an image meant to
survive.

Fixed sleeps before asserting on asynchronous work are replaced with
polls on the condition itself, using require.Eventually and
require.EventuallyWithT, and require.Never where the assertion is that
something did not happen. Polling closures assert on the CollectT they
are handed rather than on t, since testify runs them on another
goroutine, and polls that issue HTTP requests stay under the rate limit
on the routes they poll through.

Where a test needs time to have passed, the clock input is pinned
instead: staging ages are stamped with os.Chtimes on both sides of the
cleanup boundary right before each call, which also makes the 100ms
commit grace an exact case rather than something no assertion reaches,
and the RSS tests set store.Comment.Timestamp explicitly rather than
racing the wall clock into the first 100ms of a second so pubDate
matches.

chooseUnusedPort takes a port from the kernel's ephemeral range. Picking
at random out of a fixed 10000-port window let two package binaries,
which go test ./... runs concurrently, land on the same number between
the probe closing and the server binding. The start helpers fail naming
the port they waited on, and the SSL tests wait on the redirect port as
well as the TLS one.

Arbitrary budgets that nothing tests are gone: ten HTTP clients with a
one-second timeout against bolt-backed import and export, the "should
take about 100msec" assertions, and a one-second bound on noticing an
already cancelled context. Shutdown stays bounded at ten seconds so a
hang is still caught.

Two assertions get stronger. TestServerAuthHooks accepted 403 or 401
from a blocked user, an alternative that existed only because the short
token could expire mid-test; it is deterministically 403 now.
TestAdmin_BlockedList asserted two users blocked while one carried the
same 150ms ttl the next step waits to lapse, so the halves raced each
other.

goleak stops reporting the regexp2 clock goroutine, which chroma pulls
in for syntax highlighting and which lives for up to a second after the
last match with a timeout; it ends on its own but a binary finishing
inside that window was reported as leaking, and this suite now finishes
sooner. The ignore for net/http.(*Server).Shutdown goes the other way:
it no longer matches anything, with both packages run fifteen times each
under CPU oversubscription to confirm.

Two gaps the change would otherwise have opened are covered directly
rather than left to the side effects that used to cover them. The
one-second token was the only thing exercising the authenticator's
ClaimsUpd hook on refresh, so TestServerApp_ClaimsUpd now calls the hook
itself and checks admin, blocked, email and restricted-name
impersonation, including the two pass-through cases. Lifting the
open-route limit removed the last incidental exercise of the rate
limiter, so TestRateLimiter drives a burst past the allowance and checks
the refusals and that the limit is per client. Both run without a wall
clock, and both were confirmed to fail when the behaviour they cover is
removed.

Production code is untouched. The two sleeps outside test code, the 429
backoff in cmd/cleanup.go and the submit poll in store/image/image.go,
are left alone: no CI failure implicates them.

Test sleeps drop from 67 to 21, all of them either inside a
testing/synctest bubble or a poll interval. The suite runs in about 22
seconds instead of 46, mostly because
TestPublic_FindCommentsCtrl_ConsistentCount no longer paces a hundred
subtests with an 80ms sleep each to stay under the open route limit. The
300s per-package budget now matches across both workflows, the race_test
target and the documented command, and CLAUDE.md records the convention.

* Apply go fix under Go 1.27

Go 1.27 extends go fix with the modernizers, so `go fix ./...` now
rewrites patterns the language has since replaced. Running it across all
three modules produces this: legacy sync/atomic calls on plain integers
become the atomic types (notify.Service.closed, image.Service.term and
submitCount, and several test counters), reverse index loops become
slices.Backward, a Split-then-index becomes strings.Cut, counted loops
become range over an int, and interface{} becomes any in the e2e suite.

The example module needed no changes. The e2e module is behind a build
tag, so it only matches with `go fix -tags e2e ./...`.

One knock-on: prealloc can see the bound of a loop once it is written as
range over an int, so the slice it feeds is now preallocated.

Dmitry VerkhoturovandGitHub a5b2fe3cfc Consolidate the frontend toolchain onto babel, and ship one bundle (#2178)
Four upgrades that were finished but never merged, the compiler collapse
they enable, and the dependency sweep that follows. Direct
devDependencies go from 78 to 60 and dependencies from 10 to 9.

Three were doing the same job: `ts-loader` stripped types in webpack,
`babel-loader` did everything else, and `@swc/jest` repeated both for the
tests with its own copy of the JSX settings. Babel is the one that
survives, because the `data-testid` stripper has no equivalent elsewhere.

`ts-loader` ran `transpileOnly: true`, so it only stripped types, which
`@babel/preset-typescript` does; `fork-ts-checker-webpack-plugin` was
already what type-checks. Jest runs `babel-jest` against the same
`.babelrc.js` the bundle uses, passed as `configFile` because a
file-relative babel config does not reach the `node_modules` packages in
`transformIgnorePatterns`, and `jest.config.mjs` is plain ESM because a
`.ts` config is compiled against `tsconfig.json`, whose
`verbatimModuleSyntax` rejects ESM syntax in a file the package has not
declared as a module.

That removes `ts-loader`, `@swc/jest` and `@swc/core`. The last was
pinned to 1.2.205 from 2022 with no way forward, because newer builds
emit non-configurable exports and break `jest.spyOn` across 13 suites.

Babel compiles a file at a time with no type information, so it cannot
tell a type-only import from a real one and keeps the module. One line,
`import { boundActions } from './connected-comment'`, pulled the whole
redux store into `last-comments.mjs` and doubled it. `verbatimModuleSyntax`
and `@typescript-eslint/consistent-type-imports` mark them properly; the
statement has to be a separate `import type`, since verbatim semantics
keep an inline `import { type X }` and load the module anyway.

The legacy and modern compilations produced the same bytes. Both read the
same browserslist query, `defaults, not IE 11, not samsung 12` resolves to
chrome 109 and up, and nothing in the source needs transforming for that
set, so 28 of the 29 output pairs were byte-identical.

That made the module/nomodule switch worse than redundant: it served the
`.js` file to browsers with no ES module support, and those files carried
`??`, `?.` and class fields, so the fallback handed its own audience a
syntax error. There is now one bundle, always loaded as a module, in the
five templates and in the seven `site/` documents integrators copy from.
A production build emits 29 files rather than 58, in about 3 seconds
rather than 17. Two of those documents did not work at all beforehand:
the SPA snippet could not parse, and the subdomain example had an
unterminated string.

`@babel/core` 8 declares `^22.18 || >=24.11` and `size-limit` 13 declares
`^22.18 || ^24 || >=26`, so 20 was below the floor of two things installed
here; pnpm only warns, which is why every build passed. All seven places
the frontend pins it move together. `site/` is untouched: it builds with
yarn and eleventy and installs neither.

`eslint --print-config` before and after gives 173 active rules on an
application file against 172, and 172 on a spec file and a plain JS file
against 171. What is gone is three `flowtype` rules with no Flow here,
`no-new-object` and `no-new-symbol` whose upstream replacements are on,
`react/forbid-foreign-prop-types` with no propTypes anywhere, and, on TS
only, `no-useless-constructor`, whose typescript-eslint version is on at
error. `@babel/core` is pinned to 8 across the workspace because
`@jest/transform` and `istanbul-lib-instrument` depend on 7 outright; a
second scoped override holds `eslint-config-preact` on 7, since its
`@babel/eslint-parser` loads babel 7 syntax plugins.

`fast-async` rewrote every async function into nodent promise chains,
calls babel's `transform` synchronously, which babel 8 removed, and every
browser in the target list runs async natively. `prefresh` blew its stack
on `createContext` under babel 8 with no newer release to move to, which
compiled `intl.tsx` and `store/context.tsx` into throwing stubs, so
`pnpm dev:app` could not run the widget at all. `core-js` is not injected
now that `useBuiltIns` is gone, `postcss-custom-properties` was reached
directly although nothing declared it and resolved only through pnpm's
private hoist directory, and `cssnano` ran in both postcss chains although
`CssMinimizerPlugin` already uses it.

`pnpm lint`, `pnpm test` and `pnpm build` now work from `frontend/` as
`CLAUDE.md` and the contributing guide have always said they do; the
workspace root defined none of them.

Dmitry VerkhoturovandGitHub fb7b6c2cdd Serve the build-independent web assets from the backend (#2181)
* Serve the build-independent web assets from the backend

`privacy.html`, `markdown-help.html` and the `400x400.jpeg` it embeds carry
no template variable, link no script or stylesheet, and are imported by
nothing in the widget. They now live in `backend/app/webassets/assets`,
embedded there, and are served under `/web` alongside the frontend build.

`/web` reads the frontend build first and falls back to them, which is what
lets an operator replace one by dropping a file into `--web-root`. That is
what `privacy.html` needs: it describes remark42.com, while the
authorization guide tells operators to hand its URL to Google and Facebook
as their own application's privacy policy.

Only a missing file falls through. An unreadable file in the web root keeps
reporting as unreadable rather than being silently replaced by the embedded
copy, and a name the filesystem rejects reports as missing rather than as a
server error, both matching what `http.Dir` did.

The dev server serves the same directory, so the Markdown help link in the
comment form resolves on the dev port as well as in production.

The two pages are served as they are written. `markdown-help.html` was
minified before, and its formatted inline stylesheet is most of its 8.5 kB;
that is 2.4 kB more over the wire, behind the hour-long cache header the
file server already sets.

Drops `copy-webpack-plugin`, which had no other pattern, and the stylelint
entries that only ever matched these files.

* Make pnpm dev:app start again

The dev server has been failing to start on two counts, so the flow the
contributing guide documents does not run at all.

`webpack-cli` 4 drives `webpack-dev-server` 5 through the argument order
of an older major, handing it the compiler where it expects the options
object. It rejects that against its schema and exits, complaining about an
unknown `_assetEmittingPreviousFiles` property, which is a field of the
compiler. `webpack-cli` 7 is the release that declares
`webpack-dev-server` 5 as a peer.

Past that, `http-proxy-middleware` resolves to 4.1.1, which no longer
accepts the two-argument call `webpack-dev-server` makes, so the `/api`
and `/auth` proxies throw on startup. It is pulled in by the security
override for CVE-2025-32996, the only override in the file with no upper
bound: `>=2.0.10` matches every later major. Bounding it to the 2.x line
keeps the fix and the API `webpack-dev-server` calls.

With both in place `pnpm dev:app` serves the widget and the pages under
`/web` on port 9000.

Dmitry VerkhoturovandGitHub ff77f41a3a Move the e2e suite to Go and playwright-go (#2180)
* Move the e2e suite to Go and playwright-go

The seven playwright tests in `frontend/e2e` become twenty in `e2e/`, a
separate Go module driving the same browsers through playwright-go. The
npm project, its lockfile entries, its prettier config and
`Dockerfile.e2e` go with it, leaving `frontend/` a single-member
workspace.

The suite covers posting with markdown, replying and the nesting that
implies, editing inside the deadline and the backend refusing one outside
it, deleting, voting with the optimistic score observed mid-flight and
rolled back on failure, changing the sort, collapse persistence across a
reload, dev, anonymous and email sign-in end to end, the profile iframe,
and the two scripts that render into the host page rather than the
widget's own frame.

The rendering tests run in chromium, firefox and webkit. The rest sign in,
sign-in needs the dev oauth2 provider, and reaching that by name from the
host is chromium-only, so they run there alone.

`compose-e2e-test.yml` runs remark42, a second instance with a short edit
window so that path does not need a five-minute test, and mailpit, which
catches the email verification message the suite reads back. Everything
binds to the loopback interface: the stack holds a known secret and an
admin shared id, and `go test` can start it unattended. The tests run on
the host rather than in a container.

Three settings there exist for the tests rather than for realism.
`REMARK_URL` uses a hostname because the dev oauth2 server binds whatever
host it reads out of it, and a loopback bind inside a container cannot be
published. `UPDATE_LIMIT` is raised because the default of 0.5/sec rejects
any test posting twice in a row. The suite also paces its own `/auth/`
calls, which are capped at 2/sec by a bare literal in `rest.go` rather
than by a setting.

Each test gets its own comment thread from a query string on the demo
page, so nothing has to reset the database between runs.

CI gains a vet and lint job for the module, since the build tag keeps it
out of a plain `go test ./...`, and uploads a browser trace for any test
that fails.

`e2e/README.md` carries the rest: how to run it, what the stack is for,
and the widget behaviour the assertions have to work around.

* Update golangci-lint to 2.13.1 in the backend workflow

The pin sat three minors behind what the linter installs locally, so CI
checked the backend with an older set of rules than anyone running it by
hand. 2.10.1 also fetches its config schema over the network on every
`config verify`, which is a failure mode with no bearing on the code.

Both targets are clean on 2.13.1, `backend/app` and the memory_store
example.

Dmitry VerkhoturovandGitHub b8f6dc5f91 Require node 20 and record every place the version is pinned (#2168)
* Require node 20 and record every place the version is pinned

The declared floor was >=18 while CI, Docker and both .nvmrc files had
been on 20 since the pnpm 8 to 10 migration, and transitive dependencies
now require 20.18.1. The docs had drifted further still, telling
contributors to install Node 16 and PNPM 8.

* Set the node floor to the strictest dependency and keep one checklist

undici needs >=20.18.1, so a bare >=20 advertised support for 20.0 to
20.18.0, which fail dependency engine checks. frontend/CLAUDE.md already
carried a pinning checklist, so the new entries fold into it rather than
starting a rival list in the root file.

* Keep the node floor at the major, not a patch version

engines.node states the major we support. Individual dev dependencies
can be stricter within it, and chasing those patch floors into engines
and the docs would turn every lockfile refresh into a docs change.

Dmitry VerkhoturovandUmputun bf67c251c5 docs(claude): require an example tidy on any go.mod change
Previously the rule was scoped to "updating Go modules", which reads as
version bumps only. Adding or removing a dependency, or changing the `go`
directive, puts the example module out of step in exactly the same way, and
the failure is the same `test examples` step reporting "updates to go.mod
needed".

Also records that Dependabot Go module PRs need this, since the bot updates
`backend/` alone.

Milestones: one vX.Y.Z per release; decide a PR's release by whether its merge
commit is contained in a release tag (git tag --contains), not by dates; issues
get a milestone only when closed by a code change. Plus the issue-label taxonomy
(type / area / priority / contribution / resolution).

Dmitry VerkhoturovandGitHub c5121fd402 refactor(api): replace go-chi/chi router with go-pkgz/routegroup (#2103)
Migrate the REST router off go-chi/chi onto go-pkgz/routegroup (backed by the
stdlib http.ServeMux), removing the last use of go-chi from the backend:

- rest.go routes() builds the tree with routegroup (Mount/Group/Route/With) and
  net/http method+path patterns instead of chi's Get/Post/Route/Mount helpers
- chi.URLParam(...) -> r.PathValue(...) in the admin, public and private handlers
- rest_public_test.go loadPictureCtrl test uses routegroup + http.ServeMux
- rest_test.go: add TestRest_FileServerStaticAssets (bare /web -> /web/ redirect,
  cache headers, 404, directory-listing block) and update the path-traversal test
  for ServeMux normalising a literal ".." (encoded traversal is still rejected
  by the handler)
- drop go-chi/chi from go.mod, go.sum and vendor; update the CLAUDE.md reference

Dmitry VerkhoturovandUmputun 80c12a3f10 chore(deps): update Go modules
Bump Go dependencies in both backend/ and backend/_example/memory_store.

Notable updates:
- github.com/go-pkgz/lgr v0.12.1 -> v0.12.3
- github.com/klauspost/compress v1.18.2 -> v1.18.5
- github.com/PuerkitoBio/goquery v1.11.0 -> v1.12.0
- github.com/montanaflynn/stats v0.7.1 -> v0.9.0
- github.com/redis/go-redis/v9 v9.17.2 -> v9.18.0
- github.com/slack-go/slack v0.17.3 -> v0.21.1
- go.mongodb.org/mongo-driver v1.17.6 -> v1.17.9
- golang.org/x/crypto v0.48.0 -> v0.50.0
- golang.org/x/net v0.49.0 -> v0.53.0
- golang.org/x/image v0.36.0 -> v0.39.0
- golang.org/x/sys v0.41.0 -> v0.43.0
- golang.org/x/{oauth2,sync,text} minor bumps

Key markdown/sanitisation libs (bluemonday v1.0.27,
alecthomas/chroma/v2 v2.23.1, russross/blackfriday/v2 v2.1.0,
Depado/bfchroma/v2 v2.0.0) are already at the latest available
versions and were not bumped.

Verified the Chroma span-class allowlist regex in
backend/app/store/comment.go:128-131 is still fully in sync with
chroma/v2 types.go StandardTypes map (86 classes, byte-equal after
sorting). The inline comment references commit c263f6f which is
stale (Chroma is at v2 now), but the class list content is current.

Ran `go mod tidy` + `go mod vendor` + full race test suite on both
modules. All green. Added a reminder in CLAUDE.md that updating
backend/ Go modules also requires `go mod tidy` in
backend/_example/memory_store since the example module uses a
local replace directive and inherits indirect deps from the main
module.

Dmitry VerkhoturovandGitHub 06436ff9b0 Migrate batch 1 components from BEM to CSS Modules (#2014)
* feat: migrate batch 1 components from BEM to CSS Modules

Migrate 8 components from BEM to CSS Modules:
- button (7 BEM files -> 1 module)
- dropdown (7 BEM files -> 1 module)
- thread (3 BEM files -> 1 module)
- auth-panel (2 BEM files -> 1 module)
- dropdown-item, list-comments, subscribe-by-rss, settings (from batch 0 PR #2013)

Consolidates 19 BEM CSS files into 8 CSS Module files. Uses clsx for
conditional class composition, replacing bem-react-helper's b() calls.
Class naming follows the established convention: BEM block = .root,
elements = camelCase, modifiers = camelCase.

Visual regression verification on built artefacts:
- remark.css: 43,779 -> 43,299 bytes (480 bytes smaller)
- last-comments.css: 18,792 -> 18,776 bytes (16 bytes smaller)
- remark.js: 256,709 -> 304,837 bytes (48KB larger, expected: CSS Module
  classname mappings now live in JS instead of plain strings)
- Dark theme: pixel-identical (zero difference)
- Light theme: pixel-identical (0.21% diff is the native demo page
  "Toggle theme" button, not any remark42 widget element)

Also updates CLAUDE.md CSS guideline to reflect the migration status.

* Migrate remaining BEM components to CSS Modules (final batch)

Migrate the last 4 BEM components to CSS Modules, completing the
migration and removing bem-react-helper from the project entirely.

Components migrated:
- subscribe-by-email (1 BEM CSS file -> 1 module)
- comment-form + markdown-toolbar (20 BEM CSS files -> 2 modules)
- comment (19 BEM CSS files -> expanded existing module)
- root (10 BEM CSS files -> expanded existing module)

Consolidates ~50 BEM CSS files into 4 new + 2 expanded CSS Module files.
Removes bem-react-helper dependency — all components now use clsx for
conditional class composition.

Dead CSS cleanup during migration:
- Orphaned comment-actions selectors in comment theme CSS (already migrated)
- Dead BEM modifiers: comment_disabled, comment_pinned, comment_guest
- Dead element: comment__user-id (CSS existed but never used in TSX)
- Dead button type classes: comment-form__button_type_preview/_send
- Dead mix values: auth-email-login-form__back-button, comment-form__email-dropdown

Key implementation details:
- comment_highlighting stays global via :global() (imperatively added by classList)
- Bare .dark/.light theme class preserved on root wrapper (8+ modules depend on it)
- raw-content.css kept as global utility CSS (syntax highlighting)

Visual regression verification on built artefacts:
- remark.css: 43,779 -> 36,106 bytes (-17.5%)
- last-comments.css: 18,792 -> 13,955 bytes (-25.7%)
- remark.js: 256,709 -> 253,637 bytes (-1.2%)
- last-comments.js: 121,726 -> 120,795 bytes (-0.8%)
- Total: 441,006 -> 424,493 bytes (-3.7%)
- Screenshot comparison: pixel-identical across light/dark themes
