A photo sent to the chat no longer enters the album by itself. pack_add
strips it, checks it against the album and the queue, and writes it to
pending/ with a sidecar naming the people and labels the sender proposed;
the reply is "czeka na zatwierdzenie". The management page lists the queue
above the tagger, with the proposal pre-ticked, and Approve moves the file
in, mints the labels, records approved_at and asks the bot to rebuild its
table through /_reload -- the same publish path every other data change
takes, so PackHolder.reload is gone. A reload the bot refuses is reported
on the page, not rolled back: the photo is in the album either way.
The personal-data gate now reads pending/*.json too, so a label that is
still waiting for approval is forbidden in the tree already. The e2e run
boots the management page beside the bot with the same environment,
proves the queue is stripped and never reaches media/, approves it through
the real routes, and has !losowe answer with the photo afterwards without
a restart; exiftool is found through media_strip.locate() there rather
than PATH, which lacks vendor_perl on Arch.
!gadaj is dropped from !odcisz: it was within a typo of !dodaj, and the
nearest-command suggestion must never be a coin toss.

Send a photo captioned "!add_photo alfa wakacje" in one of the album's own
groups and it lands in the pack tagged with both, retrievable through !alfa
and the new !losowe immediately -- no restart, and no tagger session on the PC.
A label matching nobody becomes a custom tag, and !losowe is the only door to
one, which is what keeps a live swap a *data* swap: it can never register a
trigger or widen a command's groups.
No typed label travels. Labels become pseudonym keys in a new registry
arg_resolver, at the dispatcher, before the line that logs the command name --
so no handler, journal entry, command_uses row or reply body ever holds a word
somebody typed. The reply is counts and pseudonyms: "dodano · p1: 4 · t1: 1".
Stripping is exiftool with a *positive* check on the output, never an exit
code. ffmpeg was tried first and fails silently on photos: given a JPEG with a
real APP1 Exif segment it returned a byte-identical file, GPS intact, exit 0.
The surviving-tag allowlist is per tag *name* rather than per group, because
measurement showed a group-level "must be empty" rule rejects every format
except JPEG -- a valid PNG always reports its IHDR, an MP4 some fifty QuickTime
tags that are the container itself. Codec configuration (CompressorName,
VendorID, the HEVC parameter set) is on the list by decision: CompressorName
lives in the avc1 sample description and exiftool cannot write it at all, so
the alternative was refusing every video and every iPhone HEIC. Location and
identity tags are still refused, and the e2e run re-reads the stored files to
prove a QuickTime geotag did not survive.
.webm and .svg stay on the format allowlist and are stored *unstripped*:
exiftool 13.55 can write neither, and its SVG reader does not even surface
<metadata>. That is a deliberate, documented hole, not an oversight.
Two things this had to defuse along the way:
- personal_data_sources now reads custom.json, so "!add_photo kot <photo>"
would have outlawed the word "kot" and refused every future commit, fixable
only by hand-editing an album the committer cannot see. Minting now refuses
a word that is already a command, and the gate subtracts the repo's own
alias vocabulary from custom labels only -- curated people.json names are
never excused.
- signal_bot/external.py is now the single subprocess site in the repository,
so ruff's S603 needs exactly one scoped per-file-ignore instead of one per
module that shells out. A test asserts nothing else imports subprocess.
A failed add changes nothing: media and the three manifests are written, the
album is reloaded, and only a load that succeeds is published; a load that
fails rolls all four back and keeps serving the pack that was already working,
without raising -- Restart=always would turn a ConfigError into a loop.
977 tests, 100% branch coverage, no omits and no suppressions. scripts/e2e.sh
gains 8 scenarios driven against the real exiftool on media generated at run
time, and asserts the invariants a reply cannot: that a refused upload is not
stored, that a message with no attachment leaves custom.json byte-identical,
and that signal-cli's own copy of every ingested attachment is gone.
Closes TODO-add-photo.md.

A journal line pasted into a commit message stopped at
"group.<first few characters>...", which matched neither the full id nor the
decoded one, so the check passed and the id shipped. Eight base64 characters
now count as that group: 48 bits, unique enough that a coincidence does not
matter, short enough to catch a truncated quotation.

The leak this repository had was not carelessness with a secret. It was
somebody reaching for a real name because it was the example in front of
them -- a fixture built from a live database, an envelope pasted out of a
running container, a help text written while looking at the actual group.
Three different people-shaped mistakes, none of which a rule about "be
careful" would have stopped.
So it is a gate. The hard part is that the thing being checked must not
contain the list of what to refuse, or the check *is* the leak. It reads the
names at run time from outside: the photo pack's manifest, the message
database, the local .env. It never prints the word it matched, because this
output reaches CI logs. On a machine with none of that private data it says
"shapes only" out loud rather than passing quietly, and CI enforces the half
that needs nothing -- phone numbers, uuids and Signal group ids, compared
against an allowlist of values invented for the fixtures.
It runs on staged files, on the commit message -- where two of the leaks
actually travelled -- and over the whole tree in CI.
It paid for itself twice before it was wired up. The live test group's id was
in tests/test_config.py in two spellings, and truncated in three more files,
after four rounds of grepping by hand had pronounced the tree clean -- nobody
thinks to grep for base64. Then it refused the commit that introduced it,
because DOCS-privacy.md had used a real name as the example of a name.
An allowlist line may be scoped to one file, which is how the given names
that are also popes stay legal in popes.json and refused in every fixture
that has no business carrying them. The threshold is three characters,
because one of this group's given names is three characters long.
