* feat(nix): container-aware CLI — auto-route all subcommands into managed container
When container.enable = true, the host `hermes` CLI transparently execs
every subcommand into the managed Docker/Podman container. A symlink
bridge (~/.hermes -> /var/lib/hermes/.hermes) unifies state between host
and container so sessions, config, and memories are shared.
CLI changes:
- Global routing before subcommand dispatch (all commands forwarded)
- docker exec with -u exec_user, env passthrough (TERM, COLORTERM,
LANG, LC_ALL), TTY-aware flags
- Retry with spinner on failure (TTY: 5s, non-TTY: 10s silent)
- Hard fail instead of silent fallback
- HERMES_DEV=1 env var bypasses routing for development
- No routing messages (invisible to user)
NixOS module changes:
- container.hostUsers option: lists users who get ~/.hermes symlink
and automatic hermes group membership
- Activation script creates symlink bridge (with backup of existing
~/.hermes dirs), writes exec_user to .container-mode
- Cleanup on disable: removes symlinks + .container-mode + stops service
- Warning when hostUsers set without addToSystemPackages
* fix: address review — reuse sudo var, add chown -h on symlink update
- hermes_cli/main.py: reuse the existing `sudo` variable instead of
redundant `shutil.which("sudo")` call that could return None
- nix/nixosModules.nix: add missing `chown -h` when updating an
existing symlink target so ownership stays consistent with the
fresh-create and backup-replace branches
* fix: address remaining review items from cursor bugbot
- hermes_cli/main.py: move container routing BEFORE parse_args() so
--help, unrecognised flags, and all subcommands are forwarded
transparently into the container instead of being intercepted by
argparse on the host (high severity)
- nix/nixosModules.nix: resolve home dirs via
config.users.users.${user}.home instead of hardcoding /home/${user},
supporting users with custom home directories (medium severity)
- nix/nixosModules.nix: gate hostUsers group membership on
container.enable so setting hostUsers without container mode doesn't
silently add users to the hermes group (low severity)
* fix: simplify container routing — execvp, no retries, let it crash
- Replace subprocess.run retry loop with os.execvp (no idle parent process)
- Extract _probe_container helper for sudo detection with 15s timeout
- Narrow exception handling: FileNotFoundError only in get_container_exec_info,
catch TimeoutExpired specifically, remove silent except Exception: pass
- Collapse needs_sudo + sudo into single sudo_path variable
- Simplify NixOS symlink creation from 4 branches to 2
- Gate NixOS sudoers hint with "On NixOS:" prefix
- Full test rewrite: 18 tests covering execvp, sudo probe, timeout, permissions

* fix(nix): switch nixpkgs input from nixos-24.11 to nixos-unstable
nixos-24.11 reached EOL on 2025-06-30. For a dev tool, tracking a
frozen release branch causes dependency versions to go stale.
nixos-unstable provides rolling updates and is the conventional
choice for development packages.
* docs(website): update nix flake example

* feat: nix flake, uv2nix build, dev shell and home manager
* fixed nix run, updated docs for setup
* feat(nix): NixOS module with persistent container mode, managed guards, checks
- Replace homeModules.nix with nixosModules.nix (two deployment modes)
- Mode A (native): hardened systemd service with ProtectSystem=strict
- Mode B (container): persistent Ubuntu container with /nix/store bind-mount,
identity-hash-based recreation, GC root protection, symlink-based updates
- Add HERMES_MANAGED guards blocking CLI config mutation (config set, setup,
gateway install/uninstall) when running under NixOS module
- Add nix/checks.nix with build-time verification (binary, CLI, managed guard)
- Remove container.nix (no Nix-built OCI image; pulls ubuntu:24.04 at runtime)
- Simplify packages.nix (drop fetchFromGitHub submodules, PYTHONPATH wrappers)
- Rewrite docs/nixos-setup.md with full options reference, container
architecture, secrets management, and troubleshooting guide

* Update config.py
* feat(nix): add CI workflow and enhanced build checks
- GitHub Actions workflow for nix flake check + build on linux/macOS
- Entry point sync check to catch pyproject.toml drift
- Expanded managed-guard check to cover config edit
- Wrap hermes-acp binary in Nix package
- Fix Path type mismatch in is_managed()
* Update MCP server package name; bundled skills support
* fix reading .env. instead have container user a common mounted .env file
* feat(nix): container entrypoint with privilege drop and sudo provisioning
Container was running as non-root via --user, which broke apt/pip installs
and caused crashes when $HOME didn't exist. Replace --user with a Nix-built
entrypoint script that provisions the hermes user, sudo (NOPASSWD), and
/home/hermes inside the container on first boot, then drops privileges via
setpriv. Writable layer persists so setup only runs once.
Also expands MCP server options to support HTTP transport and sampling.

* fix group and user creation in container mode
* feat(nix): persistent /home/hermes and MESSAGING_CWD in container mode
Container mode now bind-mounts ${stateDir}/home to /home/hermes so the
agent's home directory survives container recreation. Previously it lived
in the writable layer and was lost on image/volume/options changes.
Also passes MESSAGING_CWD to the container so the agent finds its
workspace and documents, matching native mode behavior.
Other changes:
- Extract containerDataDir/containerHomeDir bindings (no more magic strings)
- Fix entrypoint chown to run unconditionally (volume mounts always exist)
- Add schema field to container identity hash for auto-recreation
- Add idempotency test (Scenario G) to config-roundtrip check
* docs: add Nix & NixOS setup guide to docs site
Add comprehensive Nix documentation to the Docusaurus site at
website/docs/getting-started/nix-setup.md, covering nix run/profile
install, NixOS module (native + container modes), declarative settings,
secrets management, MCP servers, managed mode, container architecture,
dev shell, flake checks, and full options reference.
- Register nix-setup in sidebar after installation page
- Add Nix callout tip to installation.md linking to new guide
- Add canonical version pointer in docs/nixos-setup.md
* docs: remove docs/nixos-setup.md, consolidate into website docs
Backfill missing details (restart/restartSec in full example,
gateway.pid, 0750 permissions, docker inspect commands) into
the canonical website/docs/getting-started/nix-setup.md and
delete the old standalone file.
* fix(nix): add compression.protect_last_n and target_ratio to config-keys.json
New keys were added to DEFAULT_CONFIG on main, causing the
config-drift check to fail in CI.
* fix(nix): skip checks on aarch64-darwin (onnxruntime wheel missing)
The full Python venv includes onnxruntime (via faster-whisper/STT)
which lacks a compatible uv2nix wheel on aarch64-darwin. Gate all
checks behind stdenv.hostPlatform.isLinux. The package and devShell
still evaluate on macOS.
* fix(nix): skip flake check and build on macOS CI
onnxruntime (transitive dep via faster-whisper) lacks a compatible
uv2nix wheel on aarch64-darwin. Run full checks and build on Linux
only; macOS CI verifies the flake evaluates without building.
* fix(nix): preserve container writable layer across nixos-rebuild
The container identity hash included the entrypoint's Nix store path,
which changes on every nixpkgs update (due to runtimeShell/stdenv
input-addressing). This caused false-positive identity mismatches,
triggering container recreation and losing the persistent writable layer.
- Use stable symlink (current-entrypoint) like current-package already does
- Remove entrypoint from identity hash (only image/volumes/options matter)
- Add GC root for entrypoint so nix-collect-garbage doesn't break it
- Remove global HERMES_HOME env var from addToSystemPackages (conflicted
with interactive CLI use, service already sets its own)
