With a download limit of 1, downloading one file of a share with
several files deleted the share and the files not yet downloaded.
ShareService::recordDownload() ran at the end of every download
request, one file or the ZIP alike, and deleted the share as soon as
download_count reached max_downloads. It has worked that way since
the first commit.
- One recipient's visit is one download. The first file or ZIP a
session downloads is counted when it starts, in one conditional
UPDATE that also checks the limit, so two recipients starting at
once can't both take the last download. The session remembers the
time, and for ShareService::DOWNLOAD_WINDOW_MINUTES (60) it may
start more downloads of the share without counting them, even once
the limit is reached. The claim happens in the controller before
streaming, because the session is saved before the body is sent,
and after the share key is resolved, so a request without the key
uses nothing.
- A share at its limit is closed to everyone else at once. The hourly
cleanup deletes it 24 hours after shares.last_downloaded_at (new
column), since a ZIP opens each file only when it reaches it and a
large download can outlast the hour.
- The download page of a limited share says how many downloads are
left, switches to "You have 1 hour" on the first press (Alpine, as
a download link does not render the page again), and shows the time
left on the next visit.
- The admin dashboard shows "2 of 3 downloads", marks shares at their
limit "Download limit reached" and leaves them out of Active Shares.
- Tests: the regression (3 files, limit 1: every file and the ZIP
download, counted once), another recipient, the end of the hour,
the last download going to one of two recipients, requests refused
before streaming, unlimited shares, the page notes in PHP and in
Chromium, the dashboard, and the cleanup at 23 and 25 hours. The
tests of recordDownload() and of the instant deletion are gone.

The pages were built five ways: two layouts, seven widths from 28 to
64rem and four heading styles. Every page now looks like the share
pages: a centred heading over one 40rem column of outlined cards, with
the floating toolbar below.
- <x-page> (components/page.blade.php) is the root of every page. It
draws the h1 and its line (`brand` takes the site's logo, title and
description from Admin settings), an optional `mark` and `navigation`
slot, then the content. It has no width prop: every page is the same
<x-pane width="narrow">.
- The sign-in, password reset, confirm, verify email, two-factor
challenge, setup and system password pages move onto layouts/app with
the brand heading and their form in a card titled with the task.
layouts/auth, auth-header and the settings heading partial are gone,
and so is the per-page width CSS.
- Settings put their section nav under the heading; the admin pages get
a description line each. FileUploader and ShareDownload no longer pass
the branding to their views.
- The admin dashboard's table needed about 49rem, so its shares are a
list: created above the token, which opens the share, then files,
size, downloads and expiry on two lines that wrap instead of clipping,
and one delete button. A "Sort by" select replaces the column headers
(newest, oldest, expiring soonest with never-expiring last, largest,
most downloads, most files) and resets the page. The stats stay two
by two. table.css and sort-header.css are no longer imported.
- Branding hints in Admin settings name every page the title shows on.
- Tests: PageTemplateTest renders every page once and checks one page
template, one h1 and the width, and the brand heading with its
fallbacks. FrameTest measures the page column instead of the auth
card and the 64rem main; dashboard tests follow the list and the sort
select, including expiry order. .ai/rules/views.md records <x-page>,
the CHANGELOG notes the change and the website screenshots are
regenerated.

A 6 GB upload kept a customer waiting long after its progress bar
reached 100%. The server wrote every upload three times: PHP's
temporary file, Livewire's copy of it ("Processing files...") and the
encrypted file ("Create Share Link"), each a full rewrite of a slow
disk. The unencrypted copy also stayed behind in livewire-tmp.
Now the uploader's browser encrypts each file in 16 MB chunks with
WebCrypto and PUTs them one at a time; the server checks each chunk in
memory and writes it once, already encrypted. Creating the share only
wraps its key and saves the options. A 200 MB upload through the
Docker image took 2.8 s, and its download matched byte for byte.
- SEALCHK2: a 19-byte header (chunk size, 7-byte nonce prefix), then
ciphertext and tag per chunk. Each nonce holds the chunk index and a
last-chunk flag (the STREAM construction), so cut or reordered files
fail to decrypt. SEALCHK1 and the single-block format still read.
- Envelope encryption: one random key per share. With a password it is
wrapped with Argon2id (sodium, libsodium's interactive limits) in
shares.wrapped_key, which names its parameters. Password shares from
before keep their PBKDF2-derived key.
- The upload page registers each selection with FileUploader into a
pending share of its own, lists the files with their progress, retries
a failed chunk after 1-16 s, then offers Retry; Remove and Cancel
abort. UploadChunkController only accepts chunks from the session that
started the share: a repeat is acknowledged, a skip gets 409 with the
count stored. Chunks go out as Blobs, which Chromium sends about eight
times faster than ArrayBuffers.
- Uploads need a secure context: over plain HTTP the page says HTTPS is
needed and takes no files. The Docker image gains AUTO_HTTPS, which
serves Let's Encrypt on 443 for SERVER_NAME and redirects 80; without
it the container stays on HTTP 80 behind a proxy. docker/Caddyfile was
never loaded and is gone; docker/healthcheck.sh covers both modes.
- "Download all" streams the ZIP with maennchen/zipstream-php (STORE,
ZIP64) instead of decrypting whole files into memory and writing the
archive unencrypted to /tmp.
- Pending shares count towards the quota, stay out of the admin
dashboard and 404 everywhere else. shares:cleanup deletes uploads idle
for 4 hours and Livewire temporary files older than that.
- PHP's upload limits no longer cap the admin's max file size and
default to 64M; LIVEWIRE_MAX_UPLOAD_TIME is gone and
UPLOAD_CHUNK_SIZE_MB is new.
- Tests cover the format, key wrapping, registration limits, the chunk
endpoint's answers, completing a share, the streamed ZIP, cleanup,
and in Chromium a real chunked upload and the HTTPS warning; the
selected-files overflow test runs again. README, website, CHANGELOG
and .ai/rules follow.
