A rejected fetch in AuthenticatedImage set the error state, rendered
nothing, and never asked again. The fetch effect only re-runs when its
inputs change, and for a grid tile they never do — so a transient
failure (a hiccup on cellular, or Safari cancelling loads when the tab
goes to the background) was a permanently blank tile with no request in
flight and nothing in any log. Grid passes no fallbackSrc, so there was
not even a broken-image icon to point at.
The retry is bounded and gated. Three attempts with a doubling delay
(2 s, 4 s, 8 s), and an attempt fires only once the placeholder
intersects the viewport and the document is visible, so a tile that
failed while the user was away retries when they come back rather than
while they are still gone. A new src gets a fresh budget. The
fallbackSrc path is untouched: it already renders a plain <img> and
should not loop.
Two refinements from review. A final 4xx (anything but 408 and 429)
exhausts the budget at once: an expired gallery token or a missing
photo cannot be retried into existence, and on a 68-tile viewport three
retries each would be ~200 requests that cannot succeed. And a 429's
Retry-After is honoured as the minimum delay, because the backoff alone
would spend every retry inside a 15-minute rate-limit window and leave
the tile blank after the limit had lifted. Retry-After is not
CORS-safelisted, so server.js now exposes it for split-origin
deployments alongside Content-Disposition.
The error branch now renders the same grey box as the loading state
instead of null. That is what the retry effect observes, and it is
also something the user can see. The empty-src branch now clears the
error flag too, so a tile whose src is removed after a failure does not
keep showing the failure box.
Nine tests in AuthenticatedImage.retry.test.tsx; the retry cases fail
against the previous version.
Not presented as the fix for the iOS report. It closes the one gap that
turns a transient failure into a permanent one, which the reporter asked
for in the original issue, and it is worth having on any device.

Both found by review against the correct base, and both are cases the
second stripRemoteCssUrls pass had been catching before this PR removed
it. Verified against the real functions before and after.
An escaped quote outside a string. `\'` is an escaped identifier
character, not a string opener, but the scanner stepped onto the
apostrophe, entered string mode and copied the rest of the stylesheet
unexamined — so `.hero{--marker:\';background:url(https://evil/p.gif)}`
kept a live remote URL. Escapes are now consumed as a unit outside
strings.
An unterminated quote. Trusting one meant a single stray apostrophe
disabled scanning for everything after it. An unclosed quote is a parse
error, so the safe reading is to emit it as an ordinary character and
keep scanning; a newline also ends a string, as it does in CSS.
The entity mismatch behind the second case. sanitize-html writes `"`
inside an attribute as `"`, so the scanner and the recipient's
browser disagreed about where strings begin: in
`style="font-family:"don't";background:url(...)"` the browser
decodes first, reads the apostrophe as ordinary text inside a real
string, and fetches the background — a tracking pixel by another name.
Style attributes are now decoded before scanning and re-encoded after,
which also stops the old code silently deleting quotes from the value.
Also detaches the image handlers before releasing the canvas source.
That one did NOT reproduce: measured in both Chromium and WebKit,
neither fires `error` when the attribute is removed after a successful
load. Applied anyway because the ordering is free and the failure it
would cause is silent — canvasFailed set, the canvas swapped for an
<img>, and the image decoded a second time, the exact opposite of what
the release is for.
Refs #1264, #1287
Review follow-up. The release only ran from the effect cleanup, so it
fired on unmount or a src change — while the commit message and the test
header both explained that grid tiles never unmount, which is the whole
reason the decode piles up. For the case the change exists for, it never
ran at all.
drawToCanvas now reports whether it drew, and the source Image is
released as soon as the pixels are on the canvas. Nothing redraws from
imageRef afterwards; drawToCanvas has exactly one caller. The cleanup
stays as the fallback for the paths onload cannot cover: the draw
failed, or the source changed before onload fired.
The new test pins release while still mounted, on the same src. It fails
against the previous version.
Refs #1287
AuthenticatedImage accepted the whole image-protection prop surface and
discarded it in a `void unusedProps` block. Callers computed those props
from the event's protection level and passed them in good faith, so
raising the level produced canvas rendering (via the layouts' own OR on
`protectionLevel === 'maximum'`) and nothing else the level implies.
Removes them from the interface and from every call site, so the props
state what the component actually does. Two survive because they are
real: `useCanvasRendering`, and `onProtectionViolation` — which #1297
listed as inert but which does fire, from the canvas context-menu
handler. `useWatermark` is removed as well; #1297 did not list it (it sat
outside the `unusedProps` block) but it was equally dead.
Removal rather than implementation is deliberate. The implementation
these props describe already exists in `ProtectedImage`, which is
exported from the barrel and rendered nowhere. Wiring it in is a product
decision about what protection level should mean, not a side effect of a
cleanup.
Analytics payloads inside the surviving onProtectionViolation handlers
keep their photoId/protectionLevel fields.
Refs #1297
Two follow-ups to yesterday's merges. Both were already known; neither
depends on the open question in #1287.
1. Canvas mode pinned every decoded image for the component's lifetime.
`AuthenticatedImage` keeps a detached Image in `imageRef` so drawToCanvas
can read it. The effect cleanup nulled onload/onerror and never cleared
that ref, so the Image — and the decode behind it — stayed held by a live
JS reference. A decoded <img> in the document is evictable under memory
pressure; one held by a ref is not.
That is not academic at gallery scale. The photo grid is NOT virtualised,
so a 546-photo event mounts 546 of these and none ever unmount — nothing
was ever released. The ref is cleared and the src dropped, so the browser
can reclaim without waiting for GC.
This is NOT presented as the fix for #1287. That investigation is still
open: the reporter has since shown the backend idle during a stall and
the renderer itself unresponsive for 45s, which rules out the theories
tried so far. This is a real leak on the same path, worth fixing on its
own terms while that question is settled.
2. newsletterService no longer carries its own remote-url() stripper.
It was added because the shared sanitizeCSS "blocked" remote URLs with a
CSS comment that parsers discard. #1290 replaced that with a lexer, so
the local copy is dead weight — and two definitions of "disallowed" would
drift apart. Verified the shared function covers every case the local one
did, including the quoted-paren and CSS-escape forms found in review.
Three tests on the release path, two of which fail without the fix:
unmount clears the ref and drops the src, the blob URL is revoked, and a
src change releases the previous image rather than accumulating one
pinned decode per photo a recycled tile has shown.
Hardening for the large-gallery stall. The reporter could not isolate the
cause and neither could I from static reading; these are two defects that
are wrong independently of whether they are the whole story.
Gallery grids are NOT virtualized: a 546-photo event puts 546 PhotoCards
in the DOM, each mounting its own bare fetch. Two problems there: no cap,
and a cleanup that only set a flag while the request kept running.
withImageFetchSlot now holds requests to six in flight, with the BODY read
inside the slot — fetch resolves on headers, so releasing there would have
bounded header round-trips and nothing else. Teardown aborts via
AbortController.
A request queued indefinitely is PENDING, not failed, which is why the
failure left no console error, no failed request and nothing in the
backend log.
Review follow-ups: three tiers (current lightbox slide > neighbour
prefetch > grid thumbnails), because a single FIFO put the image the user
just clicked behind hundreds of thumbnails; and a synchronous throw now
releases its slot instead of permanently draining the pool.
If it recurs, capture performance.getEntriesByType('resource') for the
stalled thumbnails — a queued request shows responseStart === 0.

Auth/access-control audit fixes (all pre-existing on main; none are
regressions). Verified end-to-end where noted.
HIGH
- Thumbnail enumeration: photoAuth granted any gallery token access to any
flat /thumbnails/thumb_* file, so a visitor to one gallery could
enumerate another (password-protected) gallery's entire thumbnail set.
Scope thumbnail access to the token's event via photos.thumbnail_path.
Live-verified: cross-event fetch now 404s, own-event still 200s.
- Bulk ownership bypass: bulk-archive/bulk-delete acted on body-supplied
event ids with no owner filter (single-event routes enforce
requireEventOwnership), letting admin/editor archive or cascade-delete
any event. Add filterOwnedEventIds; also guard rename + import-external;
tighten photo-retry to scope admin (not just editor). Fix misleading
bulk-delete comment.
MED
- verifyGalleryAccess never checked decoded.type — assert 'gallery'
instead of relying on other token types incidentally lacking eventId.
- secure-images generate-token/secure-download missing denySlideshowToken
(#646 bypass): a leaked slideshow token could download originals.
- Frontend: AuthenticatedImage + api.ts attached the gallery bearer token
to absolute/external URLs — only attach to relative same-app paths.
LOW hardening
- Pin algorithms:['HS256'] on all auth-boundary jwt.verify calls.
- crypto.timingSafeEqual for share-token + HMAC compares (utils/timingSafe).
- Remove dead photoAuth import in galleryFeedback.
Tests: new regression suites for thumbnail scoping + filterOwnedEventIds;
fixed verifyGalleryAccess.customerRevoke fixture (real customer tokens
carry type:'gallery'). Full backend suite at the pre-existing baseline
(5 suites/27 tests fail on main too), zero new failures.
- Add spinning loader in lightbox while large images are loading
- Add onLoad callback to AuthenticatedImage for canvas and img modes
- Add ETag headers based on watermark settings for HTTP cache validation
- Add watermark version query param to photo/thumbnail URLs for cache busting
- Ensures images refresh when watermark settings are enabled/changed
