feat(export): native DOCX export via html-to-docx (opt-in) (#7568)
* feat(export): native DOCX export via html-to-docx (opt-in)

Addresses #7538. The current DOCX export path shells out to LibreOffice,
which means every deployment that wants a Word download either installs
soffice (~500 MB) or loses that export. This PR adds a pure-JS
alternative: render the HTML via the existing exporthtml pipeline, then
feed it to the `html-to-docx` library in-process to produce a valid
.docx buffer — no soffice required, no subprocess spawn, no temp file
dance for the DOCX case.

Behavior:
- `settings.nativeDocxExport` (default `false`) gates the new path so
  existing deployments see zero behavior change.
- When enabled, `type === 'docx'` requests skip the LibreOffice branch,
  run `html-to-docx(html)`, and return the buffer with the
  `application/vnd.openxmlformats-officedocument.wordprocessingml.document`
  content-type.
- If the native converter throws, the handler falls through to the
  existing LibreOffice path — so flipping the flag on is safe even on a
  mixed-installation where soffice is still present as a backstop.
- Other export formats (pdf, odt, rtf, txt, html, etherpad) are
  unchanged.

Files:
- `src/package.json`: `html-to-docx` dep (pure JS, no binary reqs)
- `src/node/handler/ExportHandler.ts`: new DOCX branch gated on the
  setting, with fall-through on error
- `src/node/utils/Settings.ts`, `settings.json.template`,
  `settings.json.docker`, `doc/docker.md`: wire up the new setting +
  env var (`NATIVE_DOCX_EXPORT`)
- `src/tests/backend/specs/export.ts`: two new tests — asserts the
  exported buffer is a valid ZIP (PK\x03\x04 signature) and the
  response carries the correct content-type — both with
  `settings.soffice = 'false'` to prove the path doesn't need soffice
  at all.

Out of scope for this PR:
- Native PDF export (would need a PDF rendering step — separate
  undertaking, and the issue acknowledges the `pdfkit`/puppeteer size
  trade-off).

Closes #7538

* test(7538): skip native DOCX test when html-to-docx isn't installed

The upgrade-from-latest-release CI job installs deps from the previous
release's package.json (before this PR adds html-to-docx) and then
git-checkouts this branch's code without re-running pnpm install.
Under that one workflow the new test can't find the module and fails
on the LibreOffice fallback, masking that the native path actually
works in every normal install.

Guard the describe block with require.resolve('html-to-docx'); Mocha's
this.skip() on before cascades to the sibling its. Regular backend
tests (pnpm install against this branch's lockfile) still exercise it.

* docs(7538): spec for soffice-free DOCX/PDF export and DOCX import

Captures the agreed scope expansion of PR #7568: replace the flag-gated
native DOCX path with a soffice-first selection cascade, add native PDF
export via pdfkit + a small htmlparser2-driven walker, and add native
DOCX import via mammoth. Also defines a shared HTML sanitizer
(stripRemoteImages) used by both export converters to close the
SSRF surface that Qodo flagged on the html-to-docx path.

The spec drops the nativeDocxExport setting and its env var; with
soffice configured, behavior is unchanged, and with soffice null,
docx/pdf export and docx import all work in-process. odt/doc/rtf
(and pdf import) keep needing soffice and are documented as such.

* docs(7538): implementation plan for native DOCX/PDF and DOCX import

Bite-sized TDD task breakdown of the soffice-free export/import work:
rebase, deps, sanitizer, PDF walker, mammoth wrapper, ExportHandler
cascade, route guard, ImportHandler branch, UI fix, flag rollback,
verification + Qodo reply.

* chore(7538): add pdfkit, htmlparser2, mammoth deps

Pure-JS, no native binaries:
- pdfkit ^0.18.0  (PDF rendering)
- htmlparser2 ^12 (SAX parser used by walker + sanitizer)
- mammoth ^1.12   (DOCX -> HTML for native import)
- @types/pdfkit ^0.17 (dev)

* feat(7538): add stripRemoteImages HTML sanitizer

Drops <img src=> elements pointing at non-data, non-relative URLs to
prevent the DOCX/PDF converters from making outbound requests via
plugin-modified HTML. Closes Qodo finding #4 against the
html-to-docx path; will be wired into both export branches in
the cascade refactor.

* feat(7538): native PDF export via pdfkit + htmlparser2 walker

Renders pad HTML to a PDF Buffer in-process: headings, paragraphs,
lists, links, inline emphasis, data:-URI images. Remote images are
explicitly skipped at the walker (defense-in-depth on top of the
shared stripRemoteImages sanitizer).

PDFs are emitted with compress:false so accessibility/SEO indexers
that don't FlateDecode can still extract text. Pads are small enough
that the size cost is negligible.

Walker is 167 LOC, well under the spec's 500-LOC bail-out
threshold for switching to pdfmake+html-to-pdfmake+jsdom.

* feat(7538): native DOCX import via mammoth

Wraps mammoth.convertToHtml so a soffice-less Etherpad can ingest
.docx files. Images are coerced to data: URIs at the converter
boundary so the import pipeline never sees a remote src=.

Includes a tiny generated DOCX fixture (heading, paragraph, list)
under tests/backend/specs/fixtures/ for both this wrapper test and
the upcoming end-to-end import test.

* feat(7538): soffice-first cascade in ExportHandler

Replaces the flag-gated DOCX branch with a deterministic dispatch:
soffice if configured, native DOCX/PDF otherwise, 5xx on native
error. Both native paths run plugin-modified HTML through
stripRemoteImages first.

Test changes:
- existing native DOCX block now sets soffice=null (was 'false', a
  truthy non-null string that sidestepped the route guard); fixes
  Qodo finding #3.
- new native PDF integration tests assert %PDF- header and
  application/pdf content-type with soffice=null.
- new negative test: with soffice=null, /export/odt still returns
  the 'not enabled' message.
- the legacy 500-on-export-error test now uses /bin/false so it
  exercises the soffice error path explicitly (the cascade dropped
  the ad-hoc 'false' string; .doc has no native path so this still
  works as a soffice error probe).

Integration tests for native DOCX/PDF currently fail because the
/export route guard still treats both formats as soffice-only;
the next commit fixes that.

* fix(7538): allow docx/pdf through export guard without soffice

Tightens the no-soffice block to ['odt','doc'] only — formats with
no native path. docx and pdf are handed to ExportHandler, which
dispatches to the in-process converters. Closes Qodo finding #2.

* feat(7538): native DOCX import path in ImportHandler

When soffice is null and the upload is .docx, run mammoth and feed
the resulting HTML through setPadHTML. Other office formats
(pdf/odt/doc/rtf) are explicitly rejected with uploadFailed instead
of silently falling through to the ASCII-only path.

* fix(7538): always show DOCX/PDF export links

Native paths (#7538) make DOCX and PDF available regardless of
soffice presence, so unconditionally render those links. ODT still
gates on exportAvailable. Closes Qodo finding #2 on the UI side.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* refactor(7538): drop nativeDocxExport flag

Selection is now purely soffice-presence-driven (cascade in
ExportHandler). The opt-in setting and its NATIVE_DOCX_EXPORT env
var are no longer needed -- soffice configured means soffice path;
soffice null means native path (DOCX, PDF, and DOCX import).
Reverts the additive surface introduced earlier in this PR.

Also updates the SOFFICE doc row to reflect that null no longer
means 'plain text and HTML only' -- docx/pdf export and docx
import now work natively without soffice.

* test(7538): tighten link annotation assertion

CodeQL flagged the loose 'raw.includes("etherpad.org")' as
'incomplete URL substring sanitization' (a false positive in test
context, but worth fixing). Match the full /URI (host) form
instead -- it's both more accurate (we're verifying the PDF link
annotation structure) and CodeQL-clean.

* fix(7538): cleaner DOCX/PDF output + round-trip test coverage

DOCX:
- New extractBody helper drops <head>/<style> and the leading
  newline inside <body> so html-to-docx doesn't render CSS or
  prefix paragraphs with empty space.
- New wrapLooseLines pre-processor wraps loose pad lines in <p>
  before the converter sees them. html-to-docx renders <br>
  outside <p> as a new <w:p> (full empty line in Word); inside
  <p> it correctly emits <w:br/> (soft break). Etherpad's HTML
  uses bare <br> for every line, so this was making single
  Enters look like double Enters in the Word output.

PDF:
- Walker SKIP_TAGS rejects head/style/script/title/meta/link
  content -- prior version dumped CSS into the rendered PDF.
- New breakLine() helper combines flushLine() with moveDown(1).
  pdfkit's text('', false) closes the continued run but does
  NOT advance the cursor, so consecutive runs were stacking at
  the same y-coordinate. <br>, end-of-block, and list items
  now use breakLine().
- ontext collapses runs of whitespace and drops pure-whitespace
  text nodes so pretty-printed source HTML doesn't render its
  formatting newlines.

Round-trip:
- New backend test: pad text -> DOCX export -> DOCX import ->
  new pad. Asserts content survives the trip.
- New PDF sanity test: extracts visible text from the PDF stream
  and asserts the source pad text appears verbatim.
- 6 new unit tests for extractBody and wrapLooseLines plus 1 for
  PDF walker SKIP_TAGS coverage.

* fix(7538): CodeQL ReDoS + import.ts type error

- BR_PARA_RE was /(?:\s*<br>\s*){2,}/ -- two adjacent \s* runs can
  match the same chars, so on '<br>\t<br>\t<br>...' the regex
  backtracks exponentially. Re-anchored to match a fixed first <br>
  followed by one or more additional <br>s, so each whitespace run
  has exactly one home.
- import.ts: fetchBuffer was typed Promise<Buffer> but call sites
  chained .expect(200) on it, which only works on supertest's Test
  object. Return the Test (typed any) so the chain is preserved.

* fix(7538): plugin-aware HTML cleanup, PDF text-align, monospace

ep_headings2/ep_align emit one heading-styled blank-line block after
every styled line in the pad ('<h1 style=text-align:right></h1>'),
which both html-to-docx and our pdfkit walker render as a full empty
paragraph. Plus the pdfkit walker had no support for text-align or
monospace, so right/center alignment and 'code' lines rendered the
same as plain body text.

- New dropEmptyBlocks helper strips empty h1-h6/p/code/pre/div/
  blockquote wrappers in preprocessing. Iterates so nested empties
  collapse too. Applied before both DOCX and PDF conversion.
- PDF walker now reads style='text-align:left|center|right|justify'
  on block elements (h1-6, p, div) and passes it as pdfkit's align
  option. align is applied once per continued run, then reset on
  flushLine so the next block can pick up its own value.
- PDF walker handles <code>, <tt>, <kbd>, <samp> as inline monospace
  (Courier) and <pre> as block monospace (Courier + breakLine on
  open/close).

11 new unit tests:
- 4 for dropEmptyBlocks (heading wrappers, code, nesting,
  pass-through)
- 1 for PDF text-align (compares the BT matrix x for left vs right)
- 2 for Courier in <code> and <pre>

* fix(7538): separate adjacent heading-style blocks on import

Round-trip bug: ep_headings2 emits <h1>/<h2>/<code> in pad HTML.
Mammoth round-trips them as adjacent <h1>A</h1><h2>B</h2><p>C</p>
on import. Etherpad's server-side content collector has a default
_blockElems set of just {div, p, pre, li}, and ep_headings2 only
registers the CLIENT-side aceRegisterBlockElements -- not the
server-side ccRegisterBlockElements. So h1/h2/code end up being
treated as inline by the importer, and adjacent blocks merge into
a single pad line.

Fix: insert <br> after </h1>...</h6>/</code> when followed by
another block. Server-side workaround keeps this PR self-contained
regardless of plugin version. The right long-term fix is to extend
ep_plugin_helpers' lineAttribute factory to register both hooks
(filed as a follow-up).

Tests:
- 5 unit tests for separateAdjacentHeadingBlocks
- New end-to-end round-trip test asserts H1+H2+P land on three
  separate pad lines after the import path.

Plus the prior PDF text-align/Courier/code commit also included
here:
- code/tt/kbd/samp inherit text-align from style attribute
- pre inherits text-align too

* fix(7538): blank-line round-trip + DOCX code monospace + a==c tests

DOCX round-trip dropping blank pad lines:
- wrapLooseLines now emits an explicit <p></p> marker for each blank
  line in a <br> run, instead of collapsing all gaps into a single
  paragraph break. (N consecutive <br>s -> 1 paragraph boundary +
  N-2 empty <p></p> markers, mapping to N-1 blank pad lines.)
- mammoth's docxBufferToHtml now passes ignoreEmptyParagraphs:false
  so the empty <w:p> entries survive the import side. mammoth's
  default of true was silently dropping them.
- dropEmptyBlocks no longer strips <p></p> -- that's the meaningful
  marker for the round-trip. Empty <h1>/<code>/<pre>/<div>/
  <blockquote> are still stripped (plugin noise).

DOCX <code> rendering as monospace:
- New applyMonospaceToCode wraps code/tt/kbd/samp/pre content in a
  <span style="font-family:'Courier New', monospace">. html-to-docx
  honors that and emits <w:rFonts w:ascii="Courier New".../>, which
  Word renders as Courier. The bare <code> tag is otherwise just
  a no-op for html-to-docx.
- Applied only on the DOCX export path (PDF walker already handles
  monospace via Courier font selection).

Round-trip tests:
- New a==c suite: txt, etherpad, html, docx -- export from src,
  import to dst, re-export and compare against the meaningful
  invariant (line text for binary formats; trimmed body for HTML).
- HTML test tolerates one trailing <br> per round-trip because
  setPadHTML appends a final <p> on import; this is pre-existing
  core behavior, not our bug.
- DOCX test normalizes trailing newline run (same reason).

* fix(7538): preserve <w:jc> alignment through mammoth round-trip

mammoth doesn't expose Word's paragraph alignment (`<w:jc>`) when it
converts a docx to HTML -- there's no equivalent in its style-mapping
machinery. To keep alignment through DOCX round-trips we walk the
docx's document.xml directly, pull the `w:val` from each `<w:p>`'s
`<w:jc>`, and inject `style="text-align:..."` onto the matching
block element in mammoth's output by document order.

Word's w:jc accepts more values than CSS text-align; we map left/
start, center, right/end, both/justify/distribute and skip the rest
(start/end take left/right because we don't track ltr/rtl from the
docx for now).

Combines with the upstream ep_align PR (ether/ep_align#183) for the
full round-trip: this PR makes the mammoth output carry the
alignment style; ep_align#183 makes the importer pick it up.

Closes the alignment side of #7538.

* fix(7538): preserve <a href> inside <code>/<pre> in DOCX export

html-to-docx silently drops <a href> children of <code>/<pre> tags
(and of styled <span>s, but the <code> wrapper is the active offender
here). The pad-export HTML produced by ep_headings2 + ep_align uses
<code style='text-align:right'>...<a href>...</a>...</code> for each
'Code'-style line, which lost its links on every DOCX export.

Workaround: applyMonospaceToCode now drops the code/pre/tt/kbd/samp
wrapper entirely. The non-anchor content gets wrapped in monospace
spans; anchors are emitted unstyled so they keep their hyperlink. For
block-level usage (<pre>, or <code> with an inline style attr) we
emit a wrapping <p> and forward the text-align style. Run BEFORE
wrapLooseLines so the <p> doesn't get double-wrapped.

Tests added:
- inline <code> -> just a styled span (no <code> wrapper)
- <code style='text-align:right'> -> <p style> wrap
- <pre> -> always block-wrapped
- <tt>/<kbd>/<samp> -> inline span only
- regression: <a href> inside <code> survives html-to-docx round-trip
  with both the URL in word/_rels/document.xml.rels AND a <w:hyperlink>
  in the document body

* fix(7538): HTML import line-break drift between blocks

Etherpad's HTML export wraps each pad line in <p>...</p> (or <h1>,
<code>, etc.) and then appends a <br> between lines. The closing
block tag already ends the line for contentcollector, so the trailing
<br> is redundant -- and on import the server collector counts BOTH
as line breaks, doubling every blank line between paragraphs and
inserting an extra blank between adjacent headings.

Two fixes, both gated on the runtime block-element registry so they
don't double-trigger when the underlying plugin already handles
adjacency:

1. HTML import path now runs the new collapseRedundantBrAfterBlocks
   helper before setPadHTML. Drops a single <br> immediately
   following </p>/</h1-6>/</code>/</pre>/</div>/</blockquote>/</ul>/
   </ol>/</li>/</table>/</tr>/</td>/</th>. Multiple consecutive
   <br>s after a block keep all but the first (the rest still
   represent intentional blank lines).

2. The DOCX-import separateAdjacentHeadingBlocks workaround now
   checks whether 'h1' is in the runtime ccRegisterBlockElements
   set before inserting <br>s. When ep_headings2 has the new server
   hook (per ep_plugin_helpers#14 + the upcoming ep_headings2 PR),
   the workaround correctly stays out of the way -- otherwise it
   adds an extra blank line per heading transition.

Also fixed a subtle ts-check failure on the import.ts test changes
and a leftover implicit-any in ImportDocxNative's alignment
preserver.

Tests added:
- collapseRedundantBrAfterBlocks: 5 unit tests (each block tag,
  whitespace tolerance, multiple <br> keeping intentional blanks)
- HTML import: 'does not introduce a blank line between H1 and H2',
  'preserves blank-line count between H1 and H2 (realistic shape)'
  reproduces the 5-blanks-where-2-expected bug from the user's
  round-trip pad.

1054 backend tests pass locally (the 6 failures are the pre-existing
favicon/webaccess send@1.x dotfile-path issue from running under
.claude/, doesn't reach CI).

* test(7538): skip plugin-dependent HTML import tests on no-plugin CI

The two new HTML-import-adjacency tests assume ep_headings2 (or
another plugin) has registered h1/h2 as server-side block elements
via ccRegisterBlockElements. Without that, contentcollector treats
<h1>/<h2> as inline and adjacent ones merge into a single pad line
-- making the assertions inapplicable.

CI's backend-tests job runs without plugins installed, so guard
the describe block with a runtime hooks.callAll() check and skip
when h1 isn't a registered block. Local dev with ep_headings2 (and
the local plugin patch wiring ccRegisterBlockElements) still
exercises both tests.

feat(socialMeta): settings.socialMeta.description override (#7599 follow-up) (#7691)
Issue #7599 follow-up from @stffen: the OG description has no obvious
settings.json knob and the i18n catalog default is English, but most
preview crawlers (WhatsApp, Signal, Slack, Telegram, Facebook) don't
send Accept-Language and so always hit the English fallback regardless
of how many locale files translate `pad.social.description`.

Keep the i18n catalog as the default source — translatable strings
belong in locale files, per the original Qodo review on PR #7635 — but
add an explicit `socialMeta.description` setting that wins when set as
a non-empty string, regardless of negotiated language. This is the
lever that fixes the crawler case for non-English instances without
re-introducing per-language config in settings.json (operators who
want that still use customLocaleStrings).

- Empty/whitespace overrides are treated as unset (would otherwise
  silently blank the preview).
- Override is HTML-escaped via the same path as every other value.
- og:locale stays language-negotiated; only the description is forced.
- Documented next to publicURL in settings.json.template and
  settings.json.docker (env var SOCIAL_META_DESCRIPTION). The
  customLocaleStrings example now spells out pad.social.description so
  operators discover both routes.

5 new unit specs + 4 new integration specs cover override-wins,
null/missing fallback, blank-treated-as-unset, and HTML-escaping.

Qodo review: showPrivacyBannerIfEnabled assigned config.learnMoreUrl

learnMoreUrl of `javascript:alert(1)` or `data:…<script>…` would run
script on click. Validate via URL parsing and allow only http(s) /
mailto; everything else yields no link. Playwright regression guards
the four cases (javascript, data, https, mailto).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(privacy-banner): drop unneeded !important on [hidden] rule

Class+attribute selector already outranks `.privacy-banner { display: flex }`
on specificity (0,2,0 vs 0,1,0), so `!important` was redundant. Adds a
comment explaining why so a future reader doesn't put it back.

Per Sam's review on #7549.

* refactor(privacy-banner): render as a persistent gritter, not custom DOM

Drops the bespoke #privacy-banner template + ~50 lines of popup.css and
delegates to $.gritter.add({sticky: true, position: 'bottom'}). The
notice now matches every other gritter on the pad (theme variables,
shadow, animation, (X) close), sits in the bottom corner instead of
above the editor, and inherits dark-mode handling for free.

The two dismissal modes survive intact:
  - dismissible: gritter closes on (X); before_close persists a flag
    in localStorage so the notice is suppressed on subsequent loads.
  - sticky: closes for the current session only; never persists; the
    next pad load shows it again.

learnMoreUrl still goes through the same safeUrl() filter so a
javascript:/data:/vbscript: URL can't smuggle a script handler into the
anchor (Qodo's review concern remains addressed).

Tests: src/tests/frontend-new/specs/privacy_banner.spec.ts now drives
the real showPrivacyBannerIfEnabled via a __etherpad_privacyBanner__
test hook and asserts against the rendered gritter, instead of the
previous tests that mutated DOM by hand and never exercised the
function under test. Coverage adds: enabled=false short-circuit,
dismissible-flag-respected on subsequent show, sticky-ignores-flag,
sticky-close-does-not-persist, javascript: rejection, data: rejection,
and mailto: allow-list.

* fix(privacy-banner): noreferrer + validate dismissal (Qodo)

Two follow-ups from Qodo's review on #7549:

1. The Learn-more link now sets `rel="noreferrer noopener"` (was just
   `noopener`). Without `noreferrer` the browser sends the pad URL as a
   Referer to the operator-configured external policy site, which leaks
   pad identifiers to a third party.  Matches the rel pattern already
   used by pad_utils.ts.

2. `privacyBanner.dismissal` is now validated in reloadSettings(): an
   unknown value falls back to 'dismissible' with a `logger.warn`, in
   the same shape as the existing ipLogging validation a few lines up.
   The client also guards defensively (treats anything other than the
   exact string 'sticky' as 'dismissible') so that hot-reload paths
   that skip the server validator can't silently degrade a typo'd
   'sticky' into "no close button persisted, no localStorage suppression".

Test added: spec asserts the rel attribute, and a new test exercises
the dismissal fallback (sets dismissal:'wat', asserts the gritter is

the unknown value is treated like 'dismissible').

* fix(privacy-banner): gate test hook on webdriver, align doc with sticky behavior

Two follow-ups from Qodo's second review on #7549.

Rule violation: __etherpad_privacyBanner__ was published on every pad
load even when privacyBanner.enabled was false, so the disabled-by-
default feature still added an observable global. Gate the assignment
on `navigator.webdriver` — Playwright/ChromeDriver/Selenium set this
to true; production browsers do not — so the hook is only present for
tests and the disabled path is genuinely zero-side-effect.

Bug 3 (sticky still closable): doc/privacy.md previously claimed
`dismissal: "sticky"` removes the close button, but the gritter
implementation always renders (X). Aligning the doc with reality —
sticky now means "shows on every load, but closable for the session"
— rather than adding bespoke CSS to a vanilla gritter (matches the
"don't style it differently than other gritter messages" preference
that drove the gritter migration in 906e145).

* fix(privacy-banner): allow-list keys before sending to clientVars (Qodo)

storeSettings() merges nested objects with _.defaults() and preserves
unknown nested keys, and TypeScript's Pick<> doesn't strip at runtime.
The previous wire path forwarded settings.privacyBanner by reference
into both clientVars and getPublicSettings(), so any extra keys an
operator typed (or pasted) under privacyBanner — credentials, internal
notes, anything — would have shipped to every browser on every pad
load.

Adds getPublicPrivacyBanner() in Settings.ts that returns a literal
with only {enabled, title, body, learnMoreUrl, dismissal}, and uses it
from both leak sites (PadMessageHandler.ts clientVars and
getPublicSettings()). Single source of truth for the wire shape.

feat(gdpr): HttpOnly author-token cookie (PR3 of #6701) (#7548)
* docs: PR3 GDPR anonymous identity hardening design spec

* docs: PR3 GDPR anon identity implementation plan

* feat(gdpr): ensureAuthorTokenCookie helper — HttpOnly server-set author token

* feat(gdpr): set HttpOnly author-token cookie from the pad routes

* feat(gdpr): read author token from cookie first, keep message.token fallback

* feat(gdpr): stop generating the author token client-side

* test(gdpr): server sets + reuses the HttpOnly author-token cookie

* fix+test(gdpr): parse token cookie from handshake Cookie header

socket.io handshake doesn't run cookie-parser, so socket.request.cookies
is undefined. Parse the Cookie header directly in handleClientReady so
the HttpOnly token actually resolves. Playwright spec covers HttpOnly
attribute, reload-stability, and context-isolation.

* docs(gdpr): token cookie is now HttpOnly + server-set

* fix(gdpr): close two HttpOnly token bypasses

Qodo review:
- Timeslider still ran the pre-PR3 JS-cookie path: it read
  Cookies.get('${cp}token') (which HttpOnly hides), then generated a
  fresh plaintext token and overwrote the server's HttpOnly cookie with
  it, and sent token in every socket message. Strip the token read/
  write entirely from timeslider.ts and from the outgoing message
  shape; the server reads the cookie off the socket.io handshake just
  like on /p/:pad.
- tokenTransfer re-issued the author cookie without HttpOnly, undoing
  the hardening the first time a user transferred a session. Re-set
  it as HttpOnly + Secure (on HTTPS) + SameSite=Lax. Also stop
  trusting the body-supplied token on POST: read it off req.cookies
  server-side so the client never needs JS access to the token.

feat(gdpr): pad deletion controls (PR1 of #6701) (#7546)
* docs: PR1 GDPR deletion-controls design spec

First of five GDPR PRs tracked in #6701. PR1 covers deletion controls:
one-time deletion token, allowPadDeletionByAllUsers flag, authorisation
matrix for handlePadDelete and the REST deletePad endpoint, a single
token-display modal for browser pad creators, and test coverage.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: PR1 GDPR deletion-controls implementation plan

13 TDD-structured tasks covering PadDeletionManager unit tests, socket
+ REST three-way auth, clientVars wiring, one-time token modal,
delete-with-token UI, Playwright coverage, and PR handoff.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(gdpr): scaffolding for pad deletion tokens

PadDeletionManager stores a sha256-hashed per-pad deletion token and
verifies it with timing-safe comparison. createPad / createGroupPad
return the plaintext token once on first creation, and Pad.remove()
cleans it up. Gated behind the new allowPadDeletionByAllUsers flag
which defaults to false to preserve existing behaviour.

Part of #6701 (GDPR PR1).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix+test(gdpr): lazy DB access in PadDeletionManager + unit tests

Capturing DB.db at module-load time was null until DB.init() ran, which
broke importing the module outside a live server (including from the
test runner). Switch to DB.db.* at call time and add unit tests
exercising create/verify/remove plus timing-safe comparison.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(gdpr): three-way auth for socket PAD_DELETE

Creator cookie → valid deletion token → allowPadDeletionByAllUsers flag.
Anyone else still gets the existing refusal shout.

* feat(gdpr): optional deletionToken on programmatic deletePad

* feat(gdpr): advertise optional deletionToken on REST deletePad

* test(gdpr): cover deletePad authorisation matrix via REST

* feat(gdpr): surface padDeletionToken in clientVars for creators only

Revision-0 author on their first CLIENT_READY visit receives the
plaintext token; all subsequent CLIENT_READYs receive null because
createDeletionTokenIfAbsent is idempotent. Readonly sessions and any
other user never see the token.

* i18n(gdpr): strings for deletion-token modal and delete-with-token flow

* feat(gdpr): token modal + delete-with-token disclosure markup

* feat(gdpr): show deletion token once, allow delete via recovery token

* style(gdpr): modal + delete-with-token layout

* test(gdpr): Playwright coverage for deletion-token modal + delete-with-token

* fix(test): auto-dismiss deletion-token modal in goToNewPad helper

The token modal introduced in PR1 blocks clicks for every Playwright
test that creates a new pad via the shared helper. Add a one-line
dismissal so unrelated tests keep passing, and have the deletion-token
spec navigate inline via newPadKeepingModal() when it needs the modal
open to capture the token.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(test): dismiss deletion-token modal without focus transfer

Clicking the ack button transferred focus out of the pad iframe, which
made subsequent keyboard-driven tests (Tab / Enter) silently miss the
editor. Swap the click for a page.evaluate() that hides the modal and
nulls clientVars.padDeletionToken directly, leaving focus where it was.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(gdpr): PadDeletionManager race + document createPad/deletePad

Qodo review:
- createDeletionTokenIfAbsent() was a non-atomic read-then-write. Two
  concurrent callers for the same pad could both return different
  plaintext tokens while only the later hash was stored, leaving the
  first caller with an unusable recovery token. Serialise per-pad via a
  Promise chain and add a regression test that fires 8 concurrent
  calls and asserts exactly one plaintext is emitted and validates.
- doc/api/http_api.md now documents createPad returning deletionToken
  and deletePad accepting the optional deletionToken parameter.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(gdpr): always render delete-with-token in settings popup

The rebase onto develop placed the delete-pad-with-token details inside
the pad-settings-section conditional, which is only rendered when
enablePadWideSettings is true AND the section is toggled visible.
Second-device recovery (typing the captured token on a fresh browser)
must work without pad-wide settings enabled, so move the details out
to sit alongside the existing pad_deletion_token.spec.ts expectations.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(gdpr): require valid token when supplied, gate on auth, harden a11y/i18n

- PadMessageHandler: a supplied deletion token must validate; do not fall
  back to the creator-cookie path when the token is wrong (was deleting
  the pad anyway when the creator pasted a wrong token into the field).
- Skip token issuance + UI when requireAuthentication is on (creator
  identity is stable, recovery token is redundant noise).
- Server emits messageKey instead of hardcoded English; both shout
  handlers (inline alert and global gritter) localize via html10n.
- Suppress the global "Admin message" gritter for pad.deletionToken.*
  shouts to avoid the "Admin message: undefined" duplicate.
- Token-modal a11y: role=dialog, aria-modal, aria-labelledby/describedby,
  visually-hidden label on the token input, aria-live on Copy, focus to
  the token input on open and restore on dismiss.
- Style the "Delete Pad with Token" disclosure to match the Delete pad
  button; align the Copy/value row; pad the disclosure label.

Tests: Playwright now covers the creator-with-wrong-token path, asserts
no "Admin message" / "undefined" gritter on denial; backend API test
covers requireAuthentication suppressing the token.

feat(gdpr): IP/privacy audit (PR2 of #6701) (#7547)
* docs: PR2 GDPR IP/privacy audit design spec

Second of five GDPR PRs (#6701). Audit identifies four log-sites that
leak IPs despite disableIPlogging=true, proposes a tri-state ipLogging
setting with a back-compat shim, and specifies a doc/privacy.md that
documents Etherpad's actual IP handling.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: PR2 GDPR IP/privacy audit implementation plan

7 TDD-structured tasks: anonymizeIp helper + unit tests, tri-state
ipLogging setting with disableIPlogging deprecation shim, wiring
through 5 leaking log sites, clientVars.clientIp removal, access-log
integration test, doc/privacy.md, and PR handoff.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(gdpr): anonymizeIp helper with v4/v6/v4-mapped truncation

* feat(gdpr): tri-state ipLogging setting + disableIPlogging shim

* fix(gdpr): route every IP log site through anonymizeIp

Closes four leaks where disableIPlogging was silently ignored
(rate-limit warn, both auth-log calls in webaccess, import/export
rate-limit warn) and normalises the four that did honour the flag
onto the new ipLogging tri-state via the shared helper.

* chore(gdpr): drop dead clientVars.clientIp placeholder

Server side: remove the literal '127.0.0.1' assignments from both
clientVars and collab_client_vars. Type side: drop clientIp from
ClientVarPayload and ServerVar. pad.getClientIp now returns the same
'127.0.0.1' literal as a plugin-compat shim (pad_utils.uniqueId still
uses it as a prefix).

* test(gdpr): ipLogging modes + disableIPlogging shim

* docs(gdpr): operator-facing privacy and IP handling statement

* fix(gdpr): validate ipLogging at load + regression test for log sites

Qodo review:
- settings.ipLogging is loaded as a trusted union but nothing enforced
  the shape. An unknown value (e.g. a typo or null) silently fell
  through to anonymizeIp's "truncated" branch and emitted partially
  redacted IPs. Fall back to "anonymous" with a WARN at load time.
- New regression test scans the four known log-sites for raw
  req.ip / socket.request.ip / request.ip inside logger calls that
  don't wrap through anonymizeIp / logIp, so a future edit that
  re-introduces a raw IP fails CI.

feat(updater): tier 1 — notify admin and pad users of available updates (#7601)
* docs(updater): add four-tier auto-update design spec

Four-tier opt-in self-update subsystem (off / notify / manual / auto / autonomous).
GitHub Releases as source of truth; install-method auto-detection with admin
override; in-process execution with supervisor restart; 60s drain + announce;
auto-rollback on health-check failure with crash-loop guard. Pad-side severe/
vulnerable badge that does not leak the running version. Top-level adminEmail
with escalating cadence (weekly while vulnerable, monthly while severe).

Refs: docs/superpowers/specs/2026-04-25-auto-update-design.md

* docs(updater): add PR 1 (Tier 1 notify) implementation plan

Bite-sized TDD task breakdown for shipping Tier 1 notify only:
- VersionChecker, InstallMethodDetector, UpdatePolicy, Notifier, state modules
- /admin/update/status (admin-auth) and /api/version-status (public, no version leak)
- Admin UI banner + read-only update page + nav link
- Pad-side severe/vulnerable footer badge
- Settings: updates.* block + top-level adminEmail
- Tests: vitest unit + mocha integration + Playwright admin/pad
- CHANGELOG + doc/admin/updates.md

PRs 2-4 (manual/auto/autonomous) get their own plans after PR 1 lands.

- Fix misleading 'backing off' log message — no backoff is implemented, just retries at next interval
- Remove EMPTY_STATE_FOR_TESTS re-export from state.ts; state.test.ts now imports EMPTY_STATE directly from types.ts
- Add .update-banner and .update-page CSS rules to admin/src/index.css

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(updater): address review feedback — async wrap, tier=off skip, poll race, opt-in admin gate

- Wrap /api/version-status and /admin/update/status with a small async helper
  so a rejected promise becomes next(err) instead of an unhandled rejection.
- Short-circuit route registration when updates.tier === 'off' so the heavier
  opt-out also removes the HTTP surface (matches pre-PR behavior for that case).
- Add an in-flight guard around performCheck() so overlapping interval ticks
  can't race on update-state.json writes or duplicate email decisions; track
  the initial setTimeout handle and clear it in shutdown().
- Add updates.requireAdminForStatus (default false) so admins can lock
  /admin/update/status to authenticated admin sessions without disabling the
  updater. Default false preserves current behavior (the running version is
  already exposed publicly via /health). Backend specs cover unauth → 401,
  non-admin → 403, admin → 200.
- Bump admin troubleshooting menu count test 5 → 6 to account for the new
  Update nav link.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(updater): address Qodo round-2 review feedback

Round 2 of Qodo review on #7601. Addressing the action-required items:

#1 Badge bypassed pad baseURL — derive basePath the same way
   padBootstrap.js does (`new URL('..', window.location.href).pathname`)
   and prefix the fetch with it. Subpath deployments now reach
   /<prefix>/api/version-status instead of 404ing.

#2 Updater poller could get stuck — `getCurrentState()` is now inside
   the try/finally so a one-time loadState() rejection can't leave
   `checkInFlight=true` and permanently silence polling.

#3 Updates off hung admin page — UpdatePage now self-fetches and
   renders explicit `disabled` (404), `unauthorized` (401/403), and
   `error` states instead of staying on "Loading...". Banner-driven
   prefetch is still honoured if it landed first.

#11 NaN polling interval — coerce `checkIntervalHours` to a number,
   clamp to [1h, 168h], log a warning and fall back to 6h on
   non-finite input. Math.max(1, NaN) === NaN previously meant a
   malformed settings.json could turn the poller into a tight loop.

#13 State validation accepted broken subfields — `isValid()` now
   inspects `latest.{version,tag,body,publishedAt,htmlUrl,prerelease}`,
   `vulnerableBelow[].{announcedBy,threshold}`, and
   `email.{severeAt,vulnerableAt,vulnerableNewReleaseTag}`. A
   hand-edited file with a number where a string is expected is now
   treated as corrupt and reset to EMPTY_STATE rather than crashing
   later in semver parsing or email rendering.

#14 Badge cache stampede — wrap `computeOutdated()` in a single-flight
   promise so concurrent requests at cache expiry await one shared
   computation instead of fanning out into N redundant disk reads.

Plus six new state.test.ts cases covering each new validation guard.

Pushing back on the remaining items:

#4 `updates.tier` defaults to `notify` — intentional. The whole point
   of tier 1 is to surface the "you are behind" signal to admins by
   default. Opt-in defeats the purpose; the existing failure mode
   (admin never hears about a security-relevant release) is exactly
   what this PR is fixing.

#5/#8 Admin status endpoint admin-auth — `currentVersion` is already
   public via `/health`, so wrapping the route in admin-auth doesn't
   reduce the disclosure surface meaningfully. Operators who want it
   gated set `updates.requireAdminForStatus=true` (already wired and
   covered by the comment on the route handler).

#10 Plain `https://` URLs in planning doc — planning markdown is
   viewed in editors and on GitHub where protocol-relative URLs would
   either render literally or break entirely. Keeping `https://`.

feat: Open Graph & Twitter Card metadata for pad/timeslider/home (closes #7599) (#7635)
* docs(spec): Open Graph metadata for pad pages (issue #7599)

Spec for adding og:* and twitter:card meta tags to /p/:pad,
the timeslider, and the homepage so shared links unfurl with
a useful preview in chat apps.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs(spec): expand OG spec — i18n (locale map + og:locale) and a11y (image:alt)

Address review feedback: socialDescription accepts a per-language map,
og:locale is emitted from the negotiated render language, and image:alt
attributes are emitted for screen readers in chat clients.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat: emit Open Graph & Twitter Card metadata for pad/timeslider/home

Closes #7599.

Pad URLs shared in chat apps (WhatsApp, Signal, Slack, etc.) previously
unfurled with no preview because the rendered HTML carried no OG or
Twitter Card metadata. This change emits og:title, og:description,
og:image, og:url, og:site_name, og:type, og:locale, og:image:alt and
the equivalent twitter:* tags on the pad page, the timeslider, and the
homepage.

A new settings.json key `socialDescription` controls the description.
It accepts either a plain string applied to every locale or a per-language
map keyed by BCP-47 tag with an optional `default` fallback. og:locale
is emitted from the language already negotiated via req.acceptsLanguages
and og:image:alt provides screen-reader text for chat-client previews.

Pad names from the URL are HTML-escaped before being interpolated into
og:title to prevent reflected XSS via crafted pad IDs.

Tests: src/tests/backend/specs/socialMeta.ts covers the default,
per-locale override, locale fallback, URL decoding, XSS escape, and
the timeslider/homepage variants.

Semver: minor (new setting; templates emit additional tags but no
existing behavior changes).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(test): use valid pad-name char in URL-decode test

Spaces aren't allowed in pad names — Etherpad redirected /p/Has%20Space*
to a sanitized name (302), so the og:title assertion failed. Use %2D
("-") instead, which is a valid pad-name character and still exercises
the URL-decode path.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(socialMeta): don't double-decode pad name from req.params.pad

Express has already URL-decoded :pad route params before they reach the
handler. Calling decodeURIComponent on the result throws URIError for
pad names containing a literal "%" — e.g. the URL /p/100%25 yields
req.params.pad === "100%", and decodeURIComponent("100%") throws.

This would have prevented the page from rendering for some valid pad
IDs. Drop the redundant decode and add a regression test for the "%"
case.

Reported by Qodo on PR #7635.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* refactor(socialMeta): source description from i18n catalog, drop settings key

Per review: the OG description is a translatable string and belongs in
Etherpad's locale files alongside the rest of the UI strings, not in
settings.json. Operators who want to override it per-language continue to
use the standard customLocaleStrings mechanism — no new config surface.

Changes:
- Add "pad.social.description" to src/locales/en.json (default English).
- Export i18n.locales so server-side renderers can look up translations.
- socialMeta.renderSocialMeta now takes a `locales` map and resolves
  renderLang → primary subtag → en, instead of taking a per-locale map
  from settings.
- Remove `socialDescription` from Settings.ts, settings.json.template,
  settings.json.docker (the key never shipped).
- Update tests and spec doc to reflect i18n-sourced description.

Reported by Qodo on PR #7635 (also confirmed feature is fine to land
default-on; no flag needed).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* test(socialMeta): add unit tests for pure helpers

21 cases exercising buildSocialMetaHtml and renderSocialMeta directly,
without HTTP/DB. Covers tag enumeration, HTML escaping, og:locale
region formatting, title composition (pad/timeslider/home), description
i18n resolution (exact/primary/en fallback, missing catalog), image URL
(default favicon vs absolute settings.favicon vs alt text), canonical
URL building with query-string stripping, the literal "%" no-throw
regression, and attribute-breakout escape.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(socialMeta): defend og:url/og:image against host-header poisoning

Previously og:url and og:image were built from req.protocol +
req.get('host'), both of which can be client-controlled (Host header
directly, or X-Forwarded-* under trust proxy). A crafted Host could
make the server emit OG tags pointing at an attacker's origin —
harmful if any cache fronts the response or if a vulnerable proxy
forwards the headers unsanitized.

Two-layer defense:

1. New optional setting `publicURL` lets operators pin the canonical
   origin used for shared link previews ("https://pad.example"). When
   set, og:url and og:image use it unconditionally. Sanitized at use
   time: must be http(s)://host[:port] with no path, no userinfo, no
   trailing slash; malformed values fall back to the request.

2. When `publicURL` is unset, the request-derived fallback now strictly
   validates the Host header against /^[a-z0-9]([a-z0-9.-]{0,253}[a-z0-9])?(:\d{1,5})?$/i
   and caps the scheme to "http"/"https". A crafted Host (CRLF
   injection, userinfo, "<script>") is replaced with "localhost"
   instead of being echoed into og:url.

Reported by Qodo on PR #7635.

Tests: 5 new unit cases covering publicURL preference, trailing-slash
strip, malformed-publicURL fallback, Host validation, scheme cap.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* refactor(socialMeta): tighten types, drop `any`

- `req: any` -> express `Request` (covers acceptsLanguages/protocol/get/originalUrl).
- `settings: any` -> local `SocialMetaSettings` interface narrowed to the three
  fields we actually read (title/favicon/publicURL); avoids coupling to the
  full Settings module surface.
- `availableLangs: {[k: string]: any}` -> `{[lang: string]: unknown}`; only
  keys are read, so values stay deliberately unconstrained.

No runtime change. All 26 socialMeta unit tests still pass.

Per Sam's review on #7635.

* fix(a11y): negotiate lang/dir per request and set on <html>

Server-renders the html element with `lang` and `dir` matching the
client's Accept-Language header (negotiated against availableLangs from
i18n hooks). Falls back to `en`/`ltr` if no match.

This gives screen readers a correct document language during the brief
window before client-side html10n refines it (l10n.ts already sets both
attributes after locale data loads).

* fix(a11y): dialog semantics on popups; fix aria-role typo on userlist

Adds role=dialog, aria-modal=true, and either aria-labelledby (when an
h1 is present) or aria-label (for popups without an h1) to:

  - #settings, #import_export, #embed, #skin-variants (labelledby)
  - #connectivity, #users, #mycolorpicker (aria-label)

Fixes the invalid aria-role="document" attribute on #otherusers; it's
now role=region with aria-live=polite so screen readers announce
collaborator joins/leaves.

Container aria-label values are English-only for now — Etherpad's
html10n implementation only supports localizing specific attributes
(title, alt, placeholder, etc), not aria-label on container nodes.
Localization can follow once html10n grows that affordance.

* fix(a11y): focus management and Escape-to-close for popups

Three additions to toggleDropDown / _bodyKeyEvent:

  - Remember the trigger element (document.activeElement) when opening
    a popup, so we can restore focus when it closes.
  - On open, focus the first focusable element inside the popup so
    keyboard users land inside the dialog instead of staying on the
    trigger button.
  - Escape pressed while focus is inside a popup closes it, then the
    restore-focus path runs and the trigger button is refocused.

Replaces the previous behavior where Escape from inside a popup did
nothing; users had to click outside to dismiss.

* fix(a11y): make chaticon and chat header controls real buttons

- #chaticon: <div onclick> → <button type=button> with aria-label
- #titlecross / #titlesticky: <a onClick> → <button type=button>
  with aria-label (Close chat / Pin chat to screen)
- Decorative chat-bubble glyph gets aria-hidden=true so it isn't
  read alongside the button label
- #chatcounter labelled "Unread messages"
- Inline onclick attributes moved to chat.init() handlers
- CSS reset on the new buttons (transparent bg, no border, inherit
  font/color) so they match the prior visual design
- :focus-visible outlines for keyboard users

Existing test selectors (#chaticon, #titlecross, #titlesticky) are
unchanged and continue to work — they never relied on element type.

* fix(a11y): accessible names for icon-only toolbar/export controls

- Export links (#exportetherpada, #exporthtmla, #exportplaina,
  #exportworda, #exportpdfa, #exportopena): added aria-label so the
  link is announced as e.g. "Export as PDF". The inner icon span
  gets aria-hidden=true so screen readers don't read both the icon
  text and the link label.

- Show-more toolbar toggle (.show-more-icon-btn): converted from
  <span> to <button type=button> with aria-label and aria-expanded.
  The click handler now toggles aria-expanded alongside the
  full-icons class so assistive tech reflects the open/closed state.

- Theme switcher knob: aria-label changed from "theme-switcher-knob"
  (a class-style identifier, not human text) to "Toggle theme".

Aria-label values are English-only for now. Etherpad's html10n
implementation only localizes a fixed attribute list (title, alt,
placeholder, value, innerHTML, textContent); aria-label is not
included, so a clean l10n path requires a follow-up to either
extend html10n or set aria-label client-side after locale loads.

* test(a11y): cover dialog semantics, html lang, icon button labels

New Playwright spec verifies the a11y guarantees added by this branch:

  - <html> has a non-empty lang attribute
  - settings/import_export/embed/users popups expose role=dialog,
    aria-modal=true, and either aria-labelledby (when an h1 exists)
    or aria-label (when none does)
  - Escape from inside the settings popup closes it AND restores
    focus to the trigger button
  - Export links each carry a descriptive aria-label
  - #chaticon is a real <button> with aria-label
  - #titlecross / #titlesticky are real <button>s with aria-label
  - #otherusers uses role=region + aria-live=polite + aria-label
    (and the previous aria-role typo is gone)
  - .show-more-icon-btn is a <button> with aria-label and
    aria-expanded

* fix(a11y): address Qodo review feedback from PR #7584

1. Users Escape close broken - toggleDropDown('none') intentionally
   skips the users module so switching between other popups doesn't
   hide the user list. That meant Escape couldn't dismiss the Users
   popup either. The Escape branch now checks for #users as the
   focused popup and closes it explicitly (respecting stickyUsers)
   before falling through to the normal close-all path.

2. Embed focus overridden - the rAF auto-focus in toggleDropDown
   grabbed the first focusable descendant, which stole focus from
   command handlers that target a specific control (notably the Embed
   command's #linkinput). rAF now bails out if focus is already
   inside the newly-opened popup.

3. Button click blurs :focus before toggleDropDown captures trigger -
   discovered while investigating the Firefox Playwright failure for
   "settings popup Escape restores focus". Button.bind() calls
   $(':focus').trigger('blur') before invoking the callback, so by
   the time toggleDropDown() captured document.activeElement as the
   restore target it was already <body>. The click handler now
   stashes padeditbar._lastTrigger to the clicked <button> before
   blur runs; toggleDropDown only falls back to activeElement when
   the pre-stash didn't happen (keyboard shortcut path).

4. html10n overwrites aria-label - html10n unconditionally set
   aria-label to the translated string, clobbering explicit aria-label
   on elements that also carry data-l10n-id. setAttribute now only
   fires when the element has no aria-label; explicit author labels
   win, unlabelled translated elements still get a name.

5. Button visual reset - the show-more-icon-btn and #chaticon
   conversions inherited UA default button border/background/padding,
   shifting icon glyphs visibly off-centre. Added appearance /
   background / border / padding resets.

6. Export links test assumes soffice is installed - #exportworda,
   #exportpdfa, #exportopena are removed client-side by pad_impexp.ts
   when clientVars.exportAvailable === 'no'. The test now skips links
   absent at runtime.

Verified locally: all 10 a11y_dialogs specs pass on both Chromium and
Firefox; backend suite remains 799/799 passing; ts-check clean.

* fix(a11y): close popups with no focusable content; unbreak chat-icon layout

Round 2 of #7584 review follow-ups.

1. Users popup Escape still didn't close the dialog (user-confirmed).
   Root cause: _bodyKeyEvent is bound to the OUTER document's body.
   When #users opens, the command handler tries to focus
   #myusernameedit but that input is `disabled`, so focus stays in the
   ace editor iframe. Keydown from inside the iframe does not bubble
   to the outer document, so Esc never reaches _bodyKeyEvent.
   Fix: in the open-popup rAF, if no command handler placed focus
   inside the dialog, focus the popup div itself (with tabindex=-1).
   That keeps subsequent keydown events on the outer document so
   Esc can dismiss the popup. Also broadened the Esc branch to fire
   whenever any popup is `.popup-show`, regardless of where :focus
   lives — some popups legitimately have no focusable content at
   open.
   Added a regression test that opens #users and asserts Esc closes
   it. Passes on both Chromium and Firefox.

2. Chat icon (#chaticon) visual still wrong after the first CSS fix.
   - My previous `border: 0` reset was overriding the intended
     `border: 1px solid #ccc; border-bottom: none` from the earlier
     rule. Removed `border: 0`; the earlier explicit border suffices
     to suppress UA defaults.
   - The `<span class="buttonicon">` inside `#chaticon` was picking
     up the global `.buttonicon { display: flex; }` rule meant for
     toolbar button instances, which broke the inline layout of the
     label + glyph + counter row. Added a scoped
     `#chaticon .buttonicon { display: inline; }` override.

All 11 a11y_dialogs specs pass on Chromium and Firefox. Backend
suite and ts-check remain clean.

* fix(a11y): only stash _lastTrigger for dropdown-opening buttons

Round 3 follow-up. The previous Button.bind() change stashed every
clicked toolbar button as padeditbar._lastTrigger before blurring :focus.
That was necessary for popup-opening buttons (settings, import_export,
etc.) so Escape could return focus to them — but it also fired for
non-popup toolbar buttons (list toggles, bold/italic, indent/outdent,
clearauthorship). For those, the stash held a stale reference that
interfered with subsequent editor interactions and regressed Playwright
tests: ordered_list, unordered_list, undo_clear_authorship.

Fix: only stash when the clicked command is a registered dropdown
(settings, import_export, embed, showusers, savedrevision,
connectivity). Other commands return focus to the ace editor as before
and leave _lastTrigger alone.

Verified locally on Chromium:
  - ordered_list.spec.ts: 6/6 pass (was 4/6)
  - unordered_list.spec.ts: 6/6 pass (was 4/6)
  - undo_clear_authorship.spec.ts: 2/2 pass (was 0/2)
  - a11y_dialogs.spec.ts: 11/11 pass (unchanged)

* fix(a11y): address Qodo review round 4 for PR #7584

#1 Stale aria-label after relocalize
  html10n.translateNode() refused to overwrite any existing aria-label,
  which also skipped updates on language change (pad.applyLanguage()
  re-runs localize). Use a `data-l10n-aria-label="true"` marker: set
  aria-label + marker when html10n populates it, overwrite only if the
  marker is present. Explicit template-supplied aria-labels stay as-is;
  html10n-generated ones refresh on relocalize.

#2 Escape won't close colorpicker
  _bodyKeyEvent caught Escape on any `.popup.popup-show` but only
  closed dropdown popups via toggleDropDown('none'). Popups opened
  outside the editbar framework (#mycolorpicker, toggled directly by
  pad_userlist.ts) stayed open while preventDefault() swallowed the
  key. Now the Escape branch manually closes any popup that
  toggleDropDown('none') cannot reach (non-dropdown ids, plus #users
  unless pinned) and leaves registered dropdowns for toggleDropDown to
  close so its focus-restore sees the transition.

#3 Stale focus restoration
  toggleDropDown('none') restored focus to _lastTrigger even when no
  popup was open on entry, which meant background callers
  (connectivity setup, periodic state handling) could yank focus out
  of the editor to a stale toolbar button. Gated the restore on
  `wasAnyOpen === true` so it only fires when there was a popup to
  close.

#11 English aria-label overrides i18n (export links, chat icon)
  Removed the hard-coded English aria-label from export anchors and
  removed aria-hidden from their inner localized spans. Screen readers
  now get the localized child text as the accessible name (Etherpad,
  HTML, PDF, etc.), matching the visible UI language.
  Removed the English aria-label from #chaticon and #titlesticky as
  well — both have data-l10n-id, so html10n populates a localized
  aria-label via the marker mechanism in #1. #titlecross keeps its
  static aria-label because it has no data-l10n-id yet.

#4 4-space indent in a11y spec
  Two tests had continuation lines at 4-space indent violating the
  repo's 2-space rule. Folded the signatures onto one line.

Updated a11y_dialogs.spec.ts to assert accessible-name presence rather
than hard-coded English for elements whose names now come from the
localized text. Still asserts static English for #titlecross (not
localized yet).

Verified locally (dev server restarted for each round):
  - a11y_dialogs.spec.ts: 11/11 on Chromium, 11/11 on Firefox
  - ordered_list + unordered_list + undo_clear_authorship: 13/13 on Chromium
  - Full backend suite: 799 passing, 0 failing
  - tsc --noEmit clean in our code

#9 Popup behavior documentation: deferred to a follow-up doc PR so
this PR stays focused on the a11y code changes. The new keyboard
behavior (Escape-to-close, focus-restore-to-trigger) is small enough
to summarize in a short doc/ addition.

fix(#7570): bundle DB drivers, add regression CI (#7572)
* docs: design spec for issue #7570 (ueberdb2 driver bundling)

Spec for the upstream ueberDB fix (move 10 drivers back from optional
peer deps to dependencies) plus downstream etherpad-lite safety net
(explicit driver list + build-test-db-drivers CI job covering all 10
via presence check and MySQL+Postgres smoke tests).

* docs: implementation plan for issue #7570 ueberdb2 driver bundling

Covers upstream ueberDB PR (move drivers from optional peer deps back
to dependencies, publish 5.0.46) and downstream etherpad-lite PR
(bump ueberdb2, defensive driver list, build-test-db-drivers CI job
with presence + MySQL + Postgres stages gating publish).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix(#7570): bundle DB drivers, add regression CI

- Bump ueberdb2 to ^5.0.47 (upstream ueberDB PR #939 re-bundles drivers
  as real dependencies instead of optional peer deps, fixing the class
  of Docker-prod "Cannot find module" failures).
- Declare all 10 ueberdb2 DB drivers as direct src dependencies as a
  defensive safety net against a future upstream drift.
- Add build-test-db-drivers CI job that blocks the publish job:
    * all-10-drivers presence check in the built prod image
    * end-to-end MySQL smoke (reproduces the #7570 repro)
    * end-to-end Postgres smoke
  Any stage failure blocks Docker Hub / GHCR publish.

Supersedes #7571.

* fix(ci): run driver presence test from src/ so node_modules resolves

The presence test ran node from the default cwd (/opt/etherpad-lite),
but the drivers are installed under /opt/etherpad-lite/src/node_modules
by the monorepo workspace. Adding `-w /opt/etherpad-lite/src` makes
Node resolve modules from src/node_modules where pnpm places them.

Matches how the production container itself runs: `pnpm run prod` is
invoked from src/ (cross-env + node --require tsx/cjs node/server.ts).
