Fixed multi-second hang and permanent typing latency in Fish after exiting TUIs inside Zellij and Ghostty:
- Exported fish_features = "no-query-term" in home.sessionVariables and added set -gx fish_features no-query-term to Fish's top-level shellInit. Previous attempt (set -a fish_features no-query-term in interactiveShellInit) set a local variable inside an anonymous initialization function block that went out of scope immediately after startup. Furthermore, Fish reads fish_features at binary launch before interactive init functions run. Without no-query-term exported prior to Fish startup, Fish attempted terminal feature queries (Primary Device Attributes DA1 / \e[?c and termcap) whenever a TUI (e.g. Neovim, Lazygit, Yazi) exited and returned control to Fish. Zellij drops or delays DA1 response sequences, causing Fish to block on a multi-second stdin timeout, followed by severe input reader desynchronization and typing latency on every subsequent keystroke.
- Disabled programs.ghostty.enableFishIntegration and conditionally sourced Ghostty's shell integration script in shellInit only when NOT running inside a multiplexer (not set -q ZELLIJ and not set -q TMUX). Sourcing Ghostty's shell integration inside Zellij sent duplicate and conflicting OSC 133 prompt markers and DECSCUSR cursor escape sequences to Zellij's PTY parser.

Fixed Zellij new tab directory tracking by adding __fish_update_cwd_osc override in presets/programs/zellij.nix. Fish's default OSC 7 sequence includes $hostname, which on macOS or dynamic network environments evaluates to Noah-MacBook-Pro.local or a domain suffix. Zellij compares the OSC 7 hostname against its system hostname (Noah-MacBook-Pro), finds a mismatch, and silently ignores the CWD update, leaving new tabs stuck in a previous directory or session default. Overriding __fish_update_cwd_osc to send file://<PWD> (empty hostname) ensures Zellij always updates its cached CWD on every cd and prompt render.
Fixed Firefox "profile cannot be loaded" error on macOS by removing home.file."Library/Application Support/Firefox/installs.ini". Hardcoding an installation hash in installs.ini broke whenever Firefox was updated or rebuilt in the Nix store because the nix store path changed, causing Firefox to compute a new installation hash, fail to match or write to the read-only installs.ini symlink, and error out. Firefox on macOS uses profiles.ini (managed by Home Manager) and MOZ_LEGACY_PROFILES=1 (exported by nixpkgs' launcher wrapper).

Added presets/security/corporate-ca.nix (nix-darwin) and enabled it on the lookingglass host to trust a corporate TLS-intercepting proxy's root CA. Behind the corp network, Nix fetches failed with SSL peer certificate ... self-signed certificate in certificate chain (19) because Nix's stock Mozilla CA bundle doesn't contain the interception root. The module appends the cert to security.pki.certificateFiles, which rebuilds /etc/ssl/certs/ca-certificates.crt (read by both the Nix daemon and, via NIX_SSL_CERT_FILE, client-side flake fetches).

The cert is kept out of this public repo and referenced by absolute path. It is passed as a string (not a Nix path literal) so pure flake evaluation doesn't read it at eval time, and it lives at a root-owned, world-readable path because the unprivileged nixbld build user cannot traverse $HOME (mode 0750) to read it at build time.

One-time setup on a machine behind the proxy:

# 1. Extract the self-signed corporate root from any TLS connection it MITMs
#    (the last cert in the chain, subject == issuer). Any HTTPS host works:
echo | openssl s_client -connect example.com:443 -servername example.com \
  -showcerts 2>/dev/null \
  | awk '/BEGIN CERT/{c++} c==2' > /tmp/CorpCA.pem
openssl x509 -in /tmp/CorpCA.pem -noout -subject -issuer   # sanity check

# 2. Install to the root-owned path the config points at:
sudo install -d -m 0755 -o root -g wheel /etc/ssl/corp-ca
sudo install -m 0644 -o root -g wheel /tmp/CorpCA.pem \
  /etc/ssl/corp-ca/CorpCA.pem

# 3. Bootstrap the first rebuild (which must fetch inputs over the proxy)
#    with a combined bundle, then it's permanent:
cat /etc/ssl/certs/ca-certificates.crt /etc/ssl/corp-ca/CorpCA.pem \
  > /tmp/combined-ca.crt
NIX_SSL_CERT_FILE=/tmp/combined-ca.crt nh darwin switch . --configuration lookingglass

Fixed the zellij-session fish function in presets/programs/zellij.nix truncating the session name (derived from the target directory basename) to 20 characters. Zellij names each session's Unix-domain IPC socket $TMPDIR/zellij-<uid>/<version>/<name>, and on macOS the socket path is capped at 103 bytes. The /var/folders/... $TMPDIR prefix consumes ~79 of those, leaving only ~24 chars for the name, so switching into directories with long basenames overflowed the socket path. Because switch-session had already detached from the current session by the time the new one failed to bind, the failure took down the entire terminal instead of erroring gracefully.

Added jjui config generation to jujutsu.nix in Home Manager to include custom GitHub ruleset bypass commands (ctrl+b and ctrl+shift+b).
Added overlays/cheetah3.nix to disable pythonMetadataCheckPhase for cheetah3. This fixes an issue where the NixOS rebuild fails for sabnzbd due to importlib.metadata.PackageNotFoundError: No package metadata was found for cheetah3 during the Python package evaluation in nixos-unstable.

Added overlays/paho-mqtt.nix to disable paho-mqtt's flaky, socket-based test suite. Its checkPhase hangs in the Nix sandbox and times out with a KeyboardInterrupt after ~150s, which was breaking the flame rebuild (paho-mqtt is pulled in transitively, e.g. via mealie). The override is applied through pythonPackagesExtensions so it covers every Python package set.
