# Move :main to point at the SHA tag the merge job pushed.
#
# :main is the floating tag that tracks the tip of the main branch. Every
# merge to main retags :main forward. Users who want "latest dev build"
# pull :main; users who want stable releases pull :latest.
#
# The real serialization guarantee comes from the top-level concurrency
# group (`docker-${{ github.ref }}` with `cancel-in-progress: false`),
# which ensures at most one workflow run for this ref executes at a time.
# That means two move-main steps for the same ref cannot overlap.
#
# This job has its own concurrency group as defense-in-depth: if the
# top-level group is ever loosened, queued move-mains will run serially
# in arrival order, each one running the ancestor check below and either
# advancing :main or skipping. `cancel-in-progress: false` matches the
# top-level setting — we don't want rapid pushes to cancel a queued
# move-main, because the ancestor check is the real safety mechanism
# and queueing is cheap (move-main is a ~30s registry op).
#
# Combined with the ancestor check, this means :main only ever moves
# forward in git history.

### Subprocess-per-test isolation
Every test runs in a freshly-spawned Python subprocess via the in-tree plugin
at `tests/_isolate_plugin.py`. This means module-level dicts/sets and
ContextVars from one test cannot leak into the next — the historic
`_reset_module_state` autouse fixture is gone.
Implementation notes:
- The plugin uses `multiprocessing.get_context("spawn")`, which works on
Linux, macOS, and Windows alike (POSIX `fork` is not used).
- Per-test overhead is ~0.5–1.0s (Python startup + pytest collection). xdist
parallelism amortizes this across cores; on a 20-core box the full suite
finishes in roughly the same wall time as before, but flake-free.
- `isolate_timeout` (configured in `pyproject.toml`) caps each test at 30s.
Hangs are killed and surfaced as a failure report.
- Pass `--no-isolate` to disable isolation — useful when debugging a single
test interactively, or when you specifically want to verify state leakage.
- The plugin disables itself in child processes (sentinel envvar
`HERMES_ISOLATE_CHILD=1`), so there's no fork-bomb risk.

If you can't use the wrapper (e.g. inside an IDE that shells pytest directly),
at minimum activate the venv. The isolation plugin loads automatically from
`addopts` in `pyproject.toml`, so you get the same per-test process isolation

```bash
source .venv/bin/activate # or: source venv/bin/activate
python -m pytest tests/ -q -n 4
python -m pytest tests/ -q

Worker count above 4 will surface test-ordering flakes that CI never sees.
If you need to bypass isolation for fast feedback while debugging:
```bash

# main-wrapper.sh handles arg routing (bare-exec vs. hermes
# subcommand vs. no-args), drops to the hermes user via s6-setuidgid,
# and exec's the final program so its exit code becomes the container
# exit code. Without the wrapper-as-ENTRYPOINT, leading-dash args
# like `--version` would be intercepted by /init's POSIX shell.

## Skip the API-key collection — Nous Portal
Hermes works with whatever provider you want — that's not changing. But if you'd rather not collect five separate API keys for the model, web search, image generation, TTS, and a cloud browser, **[Nous Portal](https://portal.nousresearch.com)** covers all of them under one subscription:
- **300+ models** — pick any of them with `/model <name>`
- **Tool Gateway** — web search (Firecrawl), image generation (FAL), text-to-speech (OpenAI), cloud browser (Browser Use), all routed through your sub. No extra accounts.
One command from a fresh install:
```bash
hermes setup --portal
```
That logs you in via OAuth, sets Nous as your provider, and turns on the Tool Gateway. Check what's wired up any time with `hermes portal status`. Full details on the [Tool Gateway docs page](https://hermes-agent.nousresearch.com/docs/user-guide/features/tool-gateway).
You can still bring your own keys per-tool whenever you want — the gateway is per-backend, not all-or-nothing.
---
## CLI vs Messaging Quick Reference
Hermes has two entry points: start the terminal UI with `hermes`, or run the gateway and talk to it from Telegram, Discord, Slack, WhatsApp, Signal, or Email. Once you're in a conversation, many slash commands are shared across both interfaces.

## 省去到处收集 API Key — Nous Portal
Hermes 始终允许你使用任意服务商，这点不会改变。但如果你不想为模型、网页搜索、图像生成、TTS、云浏览器分别去申请五个不同的 API Key，**[Nous Portal](https://portal.nousresearch.com)** 用一个订阅就能覆盖全部：
- **300+ 模型** — 用 `/model <name>` 随时切换
- **Tool Gateway** — 网页搜索（Firecrawl）、图像生成（FAL）、文本转语音（OpenAI）、云浏览器（Browser Use），全部通过订阅托管。无需额外注册任何账户。
全新安装时一条命令即可：
```bash
hermes setup --portal
```
它会通过 OAuth 登录、把 Nous 设为推理服务商，并启用 Tool Gateway。随时用 `hermes portal status` 查看路由状态。完整说明见 [Tool Gateway 文档](https://hermes-agent.nousresearch.com/docs/user-guide/features/tool-gateway)。
你随时可以按工具单独切回自己的 API Key — Gateway 是按工具粒度生效的，不是一刀切。
---
## CLI 与消息平台 快速对照
Hermes 有两种入口：用 `hermes` 启动终端 UI，或运行网关从 Telegram、Discord、Slack、WhatsApp、Signal 或 Email 与之对话。进入对话后，许多斜杠命令在两种界面中通用。

def force_close_tcp_sockets(client: Any) -> int:
"""Force-close underlying TCP sockets to prevent CLOSE-WAIT accumulation.
"""Abort in-flight TCP I/O by shutting down sockets WITHOUT closing FDs.
When a provider drops a connection mid-stream, httpx's ``client.close()``
performs a graceful shutdown which leaves sockets in CLOSE-WAIT until the
OS times them out (often minutes). This method walks the httpx transport
pool and issues ``socket.shutdown(SHUT_RDWR)`` + ``socket.close()`` to
force an immediate TCP RST, freeing the file descriptors.
When a provider drops a connection mid-stream — or the user issues an
interrupt — we want to unblock httpx's reader/writer immediately rather
than waiting for the kernel's per-connection timeout. ``shutdown(SHUT_RDWR)``
achieves that: it sends FIN, breaks any pending ``recv``/``send`` with EOF
or ``EPIPE``, but does NOT release the file descriptor.
Returns the number of sockets force-closed.
Historically this helper also called ``socket.close()`` so the FD got
released immediately, but that's unsafe when (as is the case for both the
interrupt-abort path and stale-call kill path) the helper runs on a
different thread than the one driving the request:
* The Python ``socket.socket`` we close here is the SAME object held by
httpx's pool, so closing it via Python sets its ``_fd`` to -1 and
future operations on that Python object fail safely.
* BUT the SSL wrapper (``ssl.SSLSocket``'s underlying OpenSSL ``BIO``)
caches the raw integer FD. Once ``os.close(fd)`` runs, the kernel may
immediately recycle that integer to the next ``open()`` call — e.g.
the kanban dispatcher opening ``kanban.db``.
* The owning worker thread then unwinds httpx, the SSL layer flushes a
pending TLS record, and the encrypted bytes get written into the

The fix is to let the owning thread own the close. ``shutdown()`` from any
thread is FD-safe; ``close()`` is not. The httpx connection's own close
path — which runs from the worker thread when it unwinds — will release
the FD via the same ``socket.socket`` object, and because Python's socket
close atomically swaps ``_fd`` to -1 *before* issuing ``os.close``, there
is no FD-aliasing window when only one thread closes.
Returns the number of sockets shut down. (Field kept as
``tcp_force_closed=N`` in the log line for backwards-compatible parsing.)

Codex / Responses API requests carry the conversational payload in
``input`` (with additional load in ``instructions`` and ``tools``), so the

context-tier scaling never fired.

- bare list -> treat as Chat Completions ``messages``

Three categories are blocked:

readable metadata that an attacker could use as a prompt-injection
carrier.
* Credential / secret stores under HERMES_HOME and the global Hermes
root: ``auth.json``, ``auth.lock``, ``.anthropic_oauth.json``,
``.env``, ``webhook_subscriptions.json``, ``auth/google_oauth.json``,
and anything under ``mcp-tokens/``. These hold plaintext provider keys,
OAuth tokens, and HMAC secrets that the agent never needs to read
directly — provider tools / gateway adapters consume them through
internal channels.
* Project-local environment files anywhere on disk: ``.env``,
``.env.local``, ``.env.development``, ``.env.production``,
``.env.test``, ``.env.staging``, ``.envrc``. These routinely hold
API keys, database passwords, and other credentials for the user's
own projects. The agent helping debug a project shouldn't normally
need to read these — ``.env.example`` is the documented-shape
substitute.
**This is NOT a security boundary.** The terminal tool runs as the
same OS user with shell access; the agent can still ``cat auth.json``
or ``cat ~/.hermes/.env`` and exfiltrate the file. The read-deny exists
as defense-in-depth that:
* Returns a clear error to models that respect tool denials, which
empirically prompts most modern models to stop rather than reach
for the shell.
* Surfaces a visible audit trail when something tries to read
credentials — easier to spot in logs than a generic ``cat``.
Treat any user-visible framing around this as "may help" rather than
"stops attackers." A determined model or malicious instruction can
always shell out.
Callers that resolve relative paths against a non-process cwd
(e.g. ``TERMINAL_CWD`` in ``tools/file_tools.py``) MUST pre-resolve
and pass the absolute path string. This function's own ``resolve()``
is anchored at the Python process cwd, so a relative input like
``"auth.json"`` would otherwise miss the denylist when the task's
terminal cwd differs from the process cwd.

"""Bitwarden Secrets Manager (`bws` CLI) integration.
Hermes pulls API keys from Bitwarden Secrets Manager at process startup
so they don't have to live in plaintext in ``~/.hermes/.env``.
Design summary
--------------
* The ``bws`` binary is auto-installed into ``<hermes_home>/bin/bws`` on
first use. Hermes pins one version (``_BWS_VERSION``) and downloads
the matching asset from the official GitHub Releases page, verifying
the SHA-256 against the release's published checksum file.
* The access token is stored in ``~/.hermes/.env`` as
``BWS_ACCESS_TOKEN`` (or whatever name the user picked in
``secrets.bitwarden.access_token_env``). This is the one
bootstrap secret — every other provider key can live in Bitwarden.
* Pulling secrets is a single ``bws secret list <project_id>
--output json`` call. We cache the result in-process for
``cache_ttl_seconds`` so back-to-back ``hermes`` invocations don't
hammer the API.
* Failures NEVER block Hermes startup. Missing binary, no network,
expired token, etc. all emit a one-line warning and continue with
whatever credentials ``.env`` already had.
The module is intentionally subprocess-driven rather than going through
the ``bitwarden-sdk-secrets`` Python package: one cross-platform binary
is easier to lazy-install than a wheels-with-Rust-extension dependency.

Transcription Provider ABC
==========================
Defines the pluggable-backend interface for speech-to-text. Providers
register instances via
:meth:`PluginContext.register_transcription_provider`; the active one
(selected via ``stt.provider`` in ``config.yaml``) services every
:func:`tools.transcription_tools.transcribe_audio` call **when the
configured name is neither a built-in (``local``, ``local_command``,
``groq``, ``openai``, ``mistral``, ``xai``) nor disabled**.
Two coexisting STT extension surfaces — in resolution order:
1. **Built-in providers** (``BUILTIN_STT_PROVIDERS`` in
:mod:`tools.transcription_tools`) — native Python implementations
for the 6 backends shipped today (faster-whisper, local_command,
Groq, OpenAI, Mistral, xAI). **Always win** — plugins cannot
shadow them. The single-env-var shell escape hatch
``HERMES_LOCAL_STT_COMMAND`` is preserved via the built-in
``local_command`` path.
2. **Plugin-registered providers** (this ABC). For new STT backends —
OpenRouter, SenseAudio, Gemini-STT, custom proprietary engines —
that need a Python implementation without modifying
``tools/transcription_tools.py``.
Built-ins-always-win is enforced at registration time
(:func:`agent.transcription_registry.register_provider` rejects names
in ``BUILTIN_STT_PROVIDERS`` with a warning) AND at dispatch time
(:func:`tools.transcription_tools._dispatch_to_plugin_provider`
re-checks defensively).
Providers live in ``<repo>/plugins/transcription/<name>/`` (built-in
plugins, none shipped today) or
``~/.hermes/plugins/transcription/<name>/`` (user-installed).

:meth:`TranscriptionProvider.transcribe` returns a dict with keys::

Text-to-Speech Provider ABC
============================
Defines the pluggable-backend interface for text-to-speech synthesis.
Providers register instances via
``PluginContext.register_tts_provider()``; the active one (selected via
``tts.provider`` in ``config.yaml``) services every ``text_to_speech``
tool call **only when the configured name is neither a built-in nor a
command-type provider declared under ``tts.providers.<name>``**.
Three coexisting TTS extension surfaces — in resolution order:
1. **Built-in providers** (``BUILTIN_TTS_PROVIDERS`` in
:mod:`tools.tts_tool`) — native Python implementations (edge, openai,
elevenlabs, …). **Always win** — plugins cannot shadow them.
2. **Command-type providers** declared under ``tts.providers.<name>:
type: command`` (PR #17843, commit ``2facea7f7``). Wire any local
CLI into Hermes with shell-template placeholders. **Wins over a
same-name plugin** — config is more local than plugin install.
3. **Plugin-registered providers** (this ABC). For backends that need a
Python SDK, streaming bytes, OAuth refresh, or voice-listing APIs
the shell-template grammar can't reasonably express.
Built-ins-always-win is enforced at registration time
(:func:`agent.tts_registry.register_provider` rejects names in
``BUILTIN_TTS_PROVIDERS`` with a warning) AND at dispatch time
(:func:`tools.tts_tool._dispatch_to_plugin_provider` re-checks
defensively). The dispatcher also rejects plugin dispatch when a same-
name command provider is configured.
Providers live in ``<repo>/plugins/tts/<name>/`` (built-in plugins, no
shipped today) or ``~/.hermes/plugins/tts/<name>/`` (user-installed).
None ship in-tree as of issue #30398 — the hook is additive
infrastructure waiting for a real consumer (Cartesia, Fish Audio, …).
Response contract
-----------------
:meth:`TTSProvider.synthesize` writes the audio bytes to ``output_path``
and returns the path as a string. Implementations should raise on
failure — the dispatcher converts exceptions into the standard
``{success: False, error: …}`` JSON envelope the rest of Hermes
expects.

#
# Security notes:
# - The dashboard service binds to 127.0.0.1 by default. It stores API
# keys; exposing it on LAN without auth is unsafe. If you want remote
# access, use an SSH tunnel or put it behind a reverse proxy that
# adds authentication — do NOT pass --insecure --host 0.0.0.0.
# - If you override entrypoint, keep /opt/hermes/docker/entrypoint.sh in
# the command chain. It drops root to the hermes user before gateway
# files such as gateway.lock are created.
# - If you override entrypoint, keep `/init` as the first command in
# the chain (or let docker use the image's default ENTRYPOINT,
# which is `["/init", "/opt/hermes/docker/main-wrapper.sh"]`).
# `/init` is s6-overlay's PID 1 — it runs the cont-init.d scripts
# (chown, profile reconcile, dashboard toggle) and sets up the
# supervision tree before any service starts. Bypassing it skips
# all of that setup and the gateway will not work correctly.
# - The gateway's API server is off unless you uncomment API_SERVER_KEY
# and API_SERVER_HOST. See docs/user-guide/api-server.md before doing

# Make supervise/ trees for ALL declared s6 services queryable and
# controllable by the unprivileged hermes user (UID 10000).
#
# Background (PR #30136 review item I4): the entire s6 lifecycle
# (s6-svc, s6-svstat, s6-svwait) is dispatched as the hermes user
# inside the container (every Hermes runtime path runs under
# ``s6-setuidgid hermes``). But s6-supervise creates each service's
# ``supervise/`` and top-level ``event/`` directory with mode 0700
# owned by its effective UID — which is root, because s6-supervise
# is spawned by s6-svscan running as PID 1. So unprivileged clients
# get EACCES on every probe / control call against the slot.
#
# Two fixes, one in each registration path:
#
# 1. For RUNTIME-registered profile gateways (created via the s6
# runtime register hooks in profiles.py): the Python helper
# ``_seed_supervise_skeleton`` pre-creates supervise/ + event/ +
# supervise/control owned by hermes BEFORE s6-svscanctl -a fires.
# s6-supervise's mkdir/mkfifo are EEXIST-safe, so it inherits our
# ownership and never tries to chown back to root.
#
# 2. For STATIC s6-rc services (dashboard, main-hermes) declared at
# image-build time under /etc/s6-overlay/s6-rc.d/*: these are
# compiled by s6-rc at boot, and s6-supervise spawns BEFORE
# cont-init.d gets to run — so by the time we're here, the
# supervise/ tree is already there as root:root 0700. We chown
# it here. s6-supervise will keep using the same files; it never
# re-asserts ownership on a running service.
#
# This script runs as root after 01-hermes-setup but before
# 02-reconcile-profiles, so the chowns are settled before the
# Python reconciler walks the scandir. Lexicographic ordering
# guarantees this — the suffix is unusual because we want to slot
# in between 01 and the existing 02-reconcile-profiles without
# renumbering both (which would be a churn-noise patch on its own).

# s6-overlay Supervision for Per-Profile Gateways in Docker — Implementation Plan
> **Status: shipped.** Phases 0–5 landed via PR
> [NousResearch/hermes-agent#30136](https://github.com/NousResearch/hermes-agent/pull/30136)
> in May 2026. This document is preserved as a post-implementation reference
> for the architecture and the resolved design questions. The phase-by-phase
> TDD walkthrough (≈2,800 lines) and the v2/v3 re-validation preambles have
> been removed — the canonical implementation history is the PR commit log
> (`git log --oneline a957ef083..a6f7171a5 -- 'docker/*' 'hermes_cli/service_manager.py' …`).
> Open Questions are collapsed into a single Decision Log table; full
> deliberations live in PR review comments.
**Goal:** Replace `tini` with s6-overlay as PID 1 in the Hermes Docker image so
that the main hermes process, the dashboard, and dynamically-created
per-profile gateways all run as supervised services (auto-restart on crash,
clean shutdown, signal forwarding, zombie reaping). Preserve every existing
`docker run …` invocation pattern — including interactive TUI.
**Architecture:** s6-overlay's `/init` is the container ENTRYPOINT, running
s6-svscan as PID 1. Main hermes and the dashboard are declared as static
s6-rc services at image build time. Per-profile gateways — which users create
*after* the image is built (`hermes profile create coder` →
`coder gateway start`) — are registered dynamically by writing service
directories under a scandir watched by s6-svscan. A `ServiceManager` protocol
abstracts the install/start/stop/restart surface across the init systems we
care about (systemd on Linux host, launchd on macOS host, Scheduled Tasks on
native Windows host, s6 inside container) and adds a second tier for runtime
service registration that only s6 implements.
**Tech Stack:**
- [s6-overlay](https://github.com/just-containers/s6-overlay) v3.2.3.0
(noarch + per-arch tarballs ~15 MB). SHA256-pinned via build ARGs;
multi-arch via `TARGETARCH` (amd64 → `x86_64`, arm64 → `aarch64`).
- Debian 13.4 base image (unchanged).
- [hadolint](https://github.com/hadolint/hadolint) for the Dockerfile +
[shellcheck](https://github.com/koalaman/shellcheck) for entrypoint scripts.
- Python subprocess wrappers for `s6-svc`, `s6-svstat`, `s6-svscanctl`.
- Existing systemd/launchd/windows surface in `hermes_cli/gateway.py` and
`hermes_cli/gateway_windows.py`.
**Scope:**
- Container-only (host-side systemd/launchd/windows behavior is preserved,
not modified).
- s6-overlay only (no pure-Python fallback).
- Architecture A (s6 owns PID 1; tini is removed).
- Interactive TUI must keep working:
`docker run -it --rm nousresearch/hermes-agent:latest --tui`.
- Dynamic registration is limited to per-profile gateways — one service per
profile, created when a profile is created, torn down when deleted. A
`gateway-default` slot is always registered for the root HERMES_HOME
profile so `hermes gateway start` (no `-p`) has somewhere to land.
**Out of scope:**
- Host-side dynamic supervision (systemd-run / launchd transient plists) —
not needed.
- Pure-Python supervisor fallback — not needed.
- Arbitrary user-defined supervised processes inside the container — only
profile gateways.
- Migration of existing per-profile systemd unit generation to s6 on the
host side.
- Non-Docker container runtimes (Podman rootless validated reactively).
- UX polish around in-container profile lifecycle (e.g. a nice status view
of all supervised profile gateways) — deferred to follow-up.

## Background From The Codebase
> **Note on line numbers:** This section refers to functions and structures
> by name only. Use `grep -n 'def <name>' <file>` to locate anything below
> if you need the current line.
### Pre-s6 container init (what we replaced)
The original `Dockerfile` declared
`ENTRYPOINT [ "/usr/bin/tini", "-g", "--", "/opt/hermes/docker/entrypoint.sh" ]`.
tini was PID 1, reaped zombies, forwarded SIGTERM to the process group. The
old `docker/entrypoint.sh`:
1. `gosu` privilege drop from root → `hermes` UID.
2. Copied `.env.example`, `cli-config.yaml.example`, `SOUL.md` into
`$HERMES_HOME` if missing.
3. Synced bundled skills via `tools/skills_sync.py`.
4. Optionally backgrounded `hermes dashboard` in a subshell when
`HERMES_DASHBOARD=1` — **not supervised**, no restart.
5. `exec hermes "$@"` — tini's sole direct child.
Known limitations: dashboard crash → stays dead; dashboard fails at startup →
silent; gateway crash → dashboard dies too. The May 4, 2026 decision was
"leave as is" because nothing in the container needed supervision then.
Adding per-profile gateway supervision changed that.
### ServiceManager surface (what we wrapped, not refactored)
All init-system logic lives in **`hermes_cli/gateway.py`** (~5,400 LOC at
re-validation). The systemd/launchd code is ~1,500 lines of that, plus a
separate **`hermes_cli/gateway_windows.py`** (~690 LOC) for Windows
Scheduled Tasks.

Container-relevant callers outside `gateway.py`:
- `hermes_cli/status.py` — gained an `s6` branch for in-container runs.
- `hermes_cli/profiles.py` — `create_profile` / `delete_profile` register and
unregister with s6 inside the container (no-op on host).
- `hermes_cli/doctor.py` — `_check_gateway_service_linger` skips on s6, and a
new "Service Supervisor" section reports main-hermes / dashboard /
profile-gateway counts via the ServiceManager.
- `hermes_cli/gateway.py::gateway_command` — the
`elif is_container():` rejection arms that refused gateway lifecycle
operations were removed; the `_dispatch_via_service_manager_if_s6` helper
intercepts start/stop/restart and routes them through s6.
### Per-profile gateway spawning
`hermes gateway start`, `coder gateway start` (profile alias), and
`hermes -p <profile> gateway start` all spawn a gateway process scoped to a
given profile. See
[Profiles: Running Gateways](https://hermes-agent.nousresearch.com/docs/user-guide/profiles#running-gateways).
On host, lifecycle is managed via per-profile systemd units
(`hermes-gateway-<profile>.service`); inside the container, an s6 service at
`/run/service/gateway-<name>/` is registered when the profile is created and
torn down when it's deleted.
**Persistence across container restart:** `/run/service/` is tmpfs —
service registrations are wiped when the container restarts. Profile
directories at `/opt/data/profiles/<name>/` live on the persistent VOLUME,
and each one records its gateway's last state in `gateway_state.json`.
`/etc/cont-init.d/02-reconcile-profiles` walks the persistent profiles on
every container boot, recreates the s6 service slots via
`hermes_cli/container_boot.py`, and auto-starts those whose last recorded
state was `running`. Profiles whose last state was `stopped`,
`startup_failed`, `starting`, or absent get their slot recreated in the
`down` state and wait for explicit user action. `docker restart` is therefore
invisible to a user with running profile gateways: they come back up;
stopped ones stay stopped.
### s6-overlay constraints
- **Root/non-root model:** `/init` runs as root to set up the supervision
tree, install signal handlers, and run the stage2 hook that does
`usermod`/`chown`. Each supervised service drops to UID 10000 via
`s6-setuidgid hermes` in its `run` script. The per-service `s6-supervise`
monitor stays root so it can signal its child regardless of UID. Net
effect: hermes and all its subprocesses run as UID 10000 exactly as
before; only the supervision tree itself runs as root.
- v3.2.3.0 has limited non-root support for running `/init` itself as
non-root — some tools (`fix-attrs`, `logutil-service`) assume root. We
don't hit this because `/init` runs as root.
- Scandir hard cap: `services_max` default 1000, configurable to 160,000.
- `/command/with-contenv` sources `/run/s6/container_environment/*` into
service env — convenient for passing `HERMES_HOME` etc.
- s6 signal semantics: service crash triggers `s6-supervise` restart after
1s; override with a `finish` script.
- Zombie reaping: PID 1 (s6-svscan) reaps all zombies non-blockingly on
SIGCHLD. Any subagent subprocess spawned by the main hermes process is
reaped automatically.
---
## Key Design Decisions
### D1. s6-overlay replaces tini entirely
Container ENTRYPOINT is `/init`, PID 1 is s6-svscan. The main hermes
process, the dashboard, and every per-profile gateway run as supervised
services. This is a single breaking change to the container contract.
### D2. Main hermes is an s6 service with container-exit semantics
The contract "container exits when `hermes` exits" is preserved via a
service `finish` script that writes to
`/run/s6-linux-init-container-results/exitcode` and calls
`/run/s6/basedir/bin/halt`. All five supported invocations work:
| `docker run <image> …` | Behavior |
|---|---|
| (no args) | `hermes` with no args, container exits when hermes exits |
| `chat -q "..."` | `hermes chat -q "..."`, container exits with hermes exit code |
| `sleep infinity` | `sleep infinity` directly (long-lived sandbox mode) |
| `bash` | interactive `bash` directly |
| `docker run -it … --tui` | interactive Ink TUI with real TTY — see D9 |
`docker/main-wrapper.sh` detects whether `$1` is an executable on PATH and
routes either to "run this as a one-shot main service" or "wrap with
hermes".
### D3. Static services at build time; dynamic (per-profile) services at runtime
s6 offers two mechanisms:
- **s6-rc** (declarative, compile-then-swap): used for main hermes and the
dashboard — they're known at image build time.
- **scandir** (drop a directory + `s6-svscanctl -a`): used for per-profile
gateways — profiles are user-created after the image is built.
Per-profile gateway service dirs live at `/run/service/gateway-<profile>/`
(tmpfs, hermes-writable). s6-svscan picks them up on rescan.
### D4. ServiceManager protocol with two methods for runtime registration
Host paths (systemd, launchd, Windows Scheduled Tasks) need only
install/start/stop/restart of pre-declared services. Inside the container,
we additionally need to register services at runtime when a profile is
created. The protocol exposes this directly:
```python
class ServiceManager(Protocol):
kind: ServiceManagerKind # "systemd" | "launchd" | "windows" | "s6" | "none"
# Lifecycle of an already-declared service
def start(self, name: str) -> None: ...
def stop(self, name: str) -> None: ...
def restart(self, name: str) -> None: ...
def is_running(self, name: str) -> bool: ...
# Runtime registration (container-only; hosts raise NotImplementedError)
def supports_runtime_registration(self) -> bool: ...
def register_profile_gateway(
self, profile: str, *,
extra_env: dict[str, str] | None = None,
) -> None: ...
def unregister_profile_gateway(self, profile: str) -> None: ...
def list_profile_gateways(self) -> list[str]: ...
```
Systemd, launchd, and Windows backends raise `NotImplementedError` on the
registration methods. Only the s6 backend implements them. Callers check
`supports_runtime_registration()` before calling.
The scope is intentionally narrow: it's specifically "register/unregister a
profile gateway," not a general-purpose process-management API.
### D5. Per-profile gateway service spec is fixed, not user-provided
Every profile gateway has the same command shape
(`hermes -p <profile> gateway run`, or `hermes gateway run` for the default
profile). The s6 backend generates the `run` script from a fixed template
given the profile name — no arbitrary command list. This keeps the API
surface tight and prevents callers from accidentally registering
non-gateway services.
Port selection is governed by the profile's `config.yaml`
(`[gateway] port = …`) — the single source of truth. (The original plan
proposed a Python-side SHA-256 port allocator with a 600-port range; it was
retired during PR review because it was dead code through the entire stack.)
### D6. Add detect_service_manager() alongside supports_systemd_services()
`supports_systemd_services()` stays as-is (host code paths unchanged). A new
`detect_service_manager() -> Literal["systemd", "launchd", "windows", "s6", "none"]`
composes existing detection functions (`is_macos()`, `is_windows()`,
`supports_systemd_services()`, `is_container()` + `_s6_running()`) and adds
an s6 branch for container detection. Host call sites continue to use the
existing functions; container-only code (the profile hooks) uses the new one.
`_s6_running()` probes `/proc/1/comm` (world-readable) and
`/run/s6/basedir`. The earlier `/proc/1/exe` probe was root-only readable
and silently failed for the unprivileged hermes user (UID 10000), making
the entire runtime-registration path inert in production — caught in PR
review.
### D7. Wrap existing systemd/launchd/windows functions, don't rewrite them
`SystemdServiceManager` / `LaunchdServiceManager` / `WindowsServiceManager`
are thin adapters over the existing `systemd_*` / `launchd_*` module-level
functions in `hermes_cli/gateway.py` and the
`gateway_windows.install/uninstall/start/stop/restart/is_installed`
functions in `hermes_cli/gateway_windows.py`. We get the abstraction
without rewriting ~2,200 LOC of working code.
### D8. Profile create/delete hooks register/unregister the s6 service
When `hermes profile create <name>` runs inside the container, the
profile-creation code path calls
`ServiceManager.register_profile_gateway(<name>)` if
`supports_runtime_registration()` is True. When `hermes profile delete
<name>` runs, it calls `unregister_profile_gateway(<name>)`. On host, both
calls are no-ops (registration not supported; existing systemd unit
generation continues to handle install/uninstall).
Existing per-profile `hermes -p <profile> gateway start/stop/restart` CLI
commands continue to work — in the container they dispatch to
`ServiceManager.start/stop/restart("gateway-<profile>")`, which translates
to `s6-svc -u`/`-d`/`-t` on the service dir.
`hermes gateway start` (no `-p`) targets a special `gateway-default` slot
that's always registered by the cont-init reconciler. Its run script omits
the `-p` flag and runs against the root `$HERMES_HOME` profile.
`--all` lifecycle (`hermes gateway stop --all`, `... restart --all`)
iterates `mgr.list_profile_gateways()` through s6 so s6's `want up`/`want
down` flips correctly. Without this, `--all` fell through to `pkill`
followed by s6-supervise auto-restart — net effect: kick instead of stop.
### D9. Interactive TUI bypasses s6 service-mode and runs as CMD for TTY passthrough
`docker run -it --rm <image> --tui` needs a real TTY connected to container
stdin/stdout for Ink raw-mode keyboard input, cursor control, and SIGWINCH.
Running the TUI as a normal s6 service fails because s6-supervise
disconnects service stdio from the container TTY (documented:
[s6-overlay#230](https://github.com/just-containers/s6-overlay/issues/230)).
**The pattern:** s6-overlay's `/init` execs a CMD as the container's "main
program" after the supervision tree is up. The CMD inherits
stdin/stdout/stderr from `/init` — which in `-it` mode is the container
TTY. The stage2 hook detects the TUI case and short-circuits the
main-hermes service so the hermes CMD becomes that main program.
```sh
# In docker/stage2-hook.sh
_is_tui_invocation() {
for arg in "$@"; do
case "$arg" in --tui|-T) return 0 ;; esac
done
case "${HERMES_TUI:-}" in 1|true|TRUE|yes) return 0 ;; esac
if [ -t 0 ] && [ $# -eq 0 ]; then return 0; fi
return 1
}
```
And in `docker/s6-rc.d/main-hermes/run`:
```sh
if [ -f /var/run/s6/container_environment/HERMES_TUI_MODE ]; then
exec sleep infinity # s6-overlay will exec CMD as the TTY-connected main
fi
exec s6-setuidgid hermes hermes ${HERMES_ARGS:-}
```
In TUI mode main hermes is effectively unsupervised (same as the pre-s6
behavior with tini — acceptable because the user is interactively
present). Dashboard and profile gateways still get full s6 supervision via
their separate services.
The integration test `test_tty_passthrough_to_container` uses `tput cols`
and `COLUMNS=123` as the probe.

## Risk Register
| Risk | Likelihood | Impact | Mitigation |
|---|---|---|---|
| Phase 2 breaks a downstream user's Dockerfile that `FROM`s ours | Medium | Medium | Release notes call out ENTRYPOINT change; the test harness (`tests/docker/`) gives high confidence in behavior parity |
| TUI TTY passthrough fails on some Docker versions | Low | High | Harness includes `test_tty_passthrough_to_container` as a hard gate; fallback plan = s6-fdholder ([s6-overlay#230](https://github.com/just-containers/s6-overlay/issues/230) Solution 2) |
| s6-overlay non-root quirks (logutil-service, fix-attrs) bite us | Low | Low | Supervisor runs as root, services drop — sidesteps these issues |
| Podman rootless UID mapping confuses s6 | Medium | Low | Documented as supported, fix reactively; a Podman + Docker environment is stood up for validation |
| Test harness is flaky (docker daemon issues, timing) | Medium | Low | Generous timeouts; skip when docker unavailable; polling helpers replace fixed sleeps in `test_container_restart.py` |
| Profile gateway crash loop masks a real config error | Low | Medium | s6 `finish` script `max_restarts` cap (planned follow-up); operators see crash-looping logs in `$HERMES_HOME/logs/gateways/<profile>/` |
| Dockerfile+entrypoint drift from linter (hadolint/shellcheck) reveals latent bugs | Low | Low | CI lint jobs catch them; fix or document ignore with rationale |
| Stale `gateway.pid` from a dead container collides with an unrelated live PID in the restarted container | Low | Medium | Cont-init reconciliation removes `gateway.pid` and `processes.json` from every profile dir on boot, before any new gateway starts |
| `docker restart` silently loses per-profile gateway registrations (tmpfs scandir wiped) | High (without mitigation) | High | Cont-init reconciliation re-registers from persistent `$HERMES_HOME/profiles/` and auto-starts those last seen `running`; outcome recorded to `$HERMES_HOME/logs/container-boot.log` (size-bounded, rotates to `.1` at 256 KiB) |
| A `running` gateway that's actually broken auto-restarts into a crash loop after every container restart | Low | Medium | s6 `finish` script `max_restarts` cap (planned); follow-up: `hermes doctor` alerts when N consecutive container restarts ended in `startup_failed` |
| `_s6_running()` detection works as root but silently fails for unprivileged hermes user, making runtime-registration path inert | High (without mitigation) | High | **Caught in PR review.** Detection now probes `/proc/1/comm` (world-readable) + `/run/s6/basedir`. Docker integration tests refactored to `docker exec -u hermes` so the realistic runtime user is exercised |
| `s6-svscanctl` from hermes hits EACCES on the root-owned control FIFO | Medium | Medium | `02-reconcile-profiles` chowns `/run/service/.s6-svscan/{control,lock}` to hermes after stage1 creates them |
| Per-service `supervise/control` FIFO is root-owned by s6-supervise, blocking `s6-svc` from hermes | Known | Medium | Surfaced cleanly as `S6CommandError` (with rc + stderr) instead of raw `CalledProcessError`. Permission fix tracked as a follow-up (small SUID helper, polling chown loop in cont-init.d, or replace `s6-svc` with `down`-marker manipulation) |
---
## Decision Log
| # | Question | Decision |
|---|---|---|
| OQ1 | Gate Phase 2 behind env var? | Ship directly (Hermes is pre-1.0; users can pin the previous image) |
| OQ2 | s6 root model | Root `/init`, drop per-service via `s6-setuidgid hermes` |
| OQ3 | Dashboard opt-in mechanism | Always declared as an s6 service; `03-dashboard-toggle` cont-init script writes a `down` marker when `HERMES_DASHBOARD` is unset so `s6-svstat` reports the slot's real state |
| OQ4 | Podman rootless | Supported, fix reactively |
| OQ5 | Service naming | `gateway-<profile>` (matches pre-existing `hermes-gateway-<profile>.service` systemd convention) |
| OQ6 | — (retired; no subagent gateways in scope) | — |
| OQ7 | Resource limits per profile gateway | Defer (no per-cgroup limits; rely on the container's overall limit) |
| OQ8 | Log persistence | `$HERMES_HOME/logs/gateways/<profile>/`. The log path is sourced from runtime `$HERMES_HOME` via `with-contenv`, NOT Python-substituted at registration time |
| OQ9 | TUI passthrough | Trust the documented [s6-overlay#230](https://github.com/just-containers/s6-overlay/issues/230) Solution 1; harness includes a TTY passthrough hard-gate test |
**Post-merge additions from PR #30136 review:**
- **Multi-arch tarballs:** `TARGETARCH` mapped to `x86_64` / `aarch64`;
per-arch tarball fetched via `curl` because `ADD` doesn't honor BuildKit
args.
- **SHA256 verification:** all three tarballs (noarch, symlinks, per-arch)
pinned via build ARGs and verified with `sha256sum -c` against a single
checksum file (avoids hadolint DL4006 piped-shell warning).
- **`gateway-default` slot:** always registered by the reconciler so
`hermes gateway start` (no `-p`) has somewhere to land.
- **Friendly lifecycle errors:** `GatewayNotRegisteredError` and
`S6CommandError` translate `CalledProcessError` into actionable CLI
messages.
- **Atomic publication in the reconciler:** mirrors
`register_profile_gateway`'s tmp+rename pattern.
- **`container-boot.log` rotation:** 256 KiB soft cap, rotated to `.1`.
- **`port` parameter retired:** allocator + kwarg were dead code through
the entire stack; `config.yaml` is the single source of truth.

## Verification Checklist
- [x] Test harness (`tests/docker/`) passes against the s6 image
- [x] hadolint + shellcheck run green in CI
- [x] `docker run -it --rm hermes-agent --tui` starts the Ink TUI with
working keyboard input, cursor control, and resize (SIGWINCH)
- [x] Dashboard crashes are recovered by s6 within ~2s
- [x] `hermes profile create test` inside a container creates
`/run/service/gateway-test/`
- [x] `hermes -p test gateway start` inside a container dispatches through s6
- [x] `hermes -p test gateway stop` inside a container cleanly stops via s6
- [x] `hermes profile delete test` inside a container removes
`/run/service/gateway-test/`
- [x] Profile gateway logs persist at
`$HERMES_HOME/logs/gateways/test/current`
- [x] `hermes status` inside the container shows `Manager: s6`
- [x] `hermes gateway start` (no `-p`) inside a container targets
`gateway-default` and runs against the root profile
- [x] `hermes gateway stop --all` / `... restart --all` iterate every
profile gateway under s6 instead of pkill-then-supervise-restart
- [x] `docker restart` survives per-profile gateway registrations via the
cont-init reconciler; running gateways come back up, stopped ones
stay down
- [x] Multi-arch image builds for both `linux/amd64` and `linux/arm64`
- [x] s6-overlay tarballs are SHA256-verified at build time
- [x] No systemd/launchd host-side functions were modified (only wrapped)

~15 minutes in, because MiniMax issues short-lived access tokens.
Returning a *callable* instead of a string lets us hook into the

callable and routes through ``_build_anthropic_client_with_bearer_hook``,

calls :func:`_refresh_minimax_oauth_state` — that helper is a no-op
when the token still has more than ``MINIMAX_OAUTH_REFRESH_SKEW_SECONDS``
of life left, so the steady-state cost is one file read + one
timestamp compare per request.
