-A key lands here when a publisher signs what Panama installs but does not

-them first. Pinning the key is what lets `dnf` verify a download before root

-Nothing here is a secret. These are public keys, and the reason to track them

-Captured on 2026-08-27 from a machine where the official package had been
-installed, at `/etc/pki/rpm-gpg/RPM-GPG-KEY-chatgpt`, where the package's own
-root scriptlet writes it. It is the key that signed both the installed
-`chatgpt` package and the live `repodata/repomd.xml.asc`.
-
-Be honest about what that is worth: OpenAI's documented instructions
-(<https://learn.chatgpt.com/docs/linux/linux-app>) are to download an RPM and
-install it, and they publish no key URL and no fingerprint to compare against.
-So this is trust established on first use and then held, not trust verified
-against the publisher. Held is the part that matters -- from here every machine
-checks the same fingerprint, and a swapped download fails instead of installing.
-
-To re-derive the fingerprint from the file:
-
-```bash
-gpg --show-keys --with-colons setup/keys/RPM-GPG-KEY-chatgpt \
-    | awk -F: '$1 == "fpr" { print $10; exit }'

-# OpenAI signs both its packages and its repository metadata, with one key, and

-# fetch them. The documented instructions are "download this RPM and install
-# it" -- and the RPM's own root scriptlet is what writes the repository file and

-# unverified download to root and letting it decide afterwards what to trust,
-# which is the one thing this repository will not do with a network response.
-#
-# So the key is pinned here instead. setup/keys/ carries a copy and records
-# where it came from; this verifies that copy's fingerprint, installs it, and
-# writes the repository itself with gpgcheck on. dnf then checks the metadata
-# signature and the package signature against that key before anything runs as
-# root, and every later upgrade goes through the same repository and the same
-# key.

-# The one download that gets to run as root, and how it earns that.
-#
-# OpenAI publishes no signing key and no fingerprint that a first install could
-# fetch and compare against: the documented instructions are to download an RPM
-# and install it, and that RPM's own root scriptlet is what decides afterwards
-# which repository and which key the machine will trust. Panama pins the key
-# instead -- setup/keys/ carries it, setup/lib/chatgpt-package verifies the copy
-# and writes the repository -- so dnf checks a signature before root sees a byte
-# of it.
-#
-# What must hold:
-#
-#   1. The pinned key is the key the library says it is. Everything else here
-#      is worthless if this drifts, and a changed key must be a failing test
-#      somebody reads rather than a quiet change of publisher.
-#   2. A pinned key that is missing, unreadable, or simply not that key stops
-#      the install and leaves the machine untouched. Failing closed is the
-#      whole point; falling back to installing anyway would be worse than
-#      never having checked.
-#   3. What it writes actually enforces the check: gpgcheck and repo_gpgcheck
-#      on, and the gpgkey pointing at the key it just installed.
-#   4. Both callers go through it, and neither hands root a downloaded RPM.
-#      The installer and the codex-desktop migration install `chatgpt` by name
-#      from that repository, which is what makes the signature mandatory.
-#
-# Hermetic: the key file is read locally, root is a stub that records what it
-# was asked to do, and the destinations are redirected into a temporary
-# directory. Nothing here contacts OpenAI or touches /etc.
