On Linux, SO_REUSEADDR only allows rebinding past TIME_WAIT (a second
live listener would need SO_REUSEPORT, which we never set), so
disabling it bought no protection there while making a quick gateway
restart fail to rebind for up to ~60s. Keep the BSD silent-split guard
on darwin, default semantics elsewhere.
E2E verified: dual-stack v4+v6 bind on one port, immediate rebind
after disconnect, and live-listener conflict still rejected.
Disable address reuse so an existing family-specific listener cannot silently split traffic with the webhook server. Normalize wildcard bind hosts for local CLI URLs and align setup documentation with the dual-stack default.
The webhook adapter defaulted to host='0.0.0.0' — IPv4 only. On Fly.io
hosted agents the edge router (hermes-agent-router) reverse-proxies public
webhook traffic to <app>.internal:8644 over 6PN, Fly's private network,
which is IPv6-only (.internal resolves to an fdaa:… address). An IPv4-only
listener is unreachable there, so public webhook POSTs to
https://<agent>.agents.nousresearch.com/webhooks/<route> never landed on
the adapter — the router's dial was refused.
Fix: DEFAULT_HOST = None, which makes aiohttp/asyncio create_server bind
BOTH address families. '::' is NOT a valid substitute: on hosts where the
kernel sets bindv6only=1 (verified on Fly machines) it yields an IPv6-only
socket, breaking the IPv4 loopback /health check and the AF_INET
port-conflict probe in connect(). None binds per-family regardless of the
sysctl. An explicit empty-string/null host in config now also normalises to
None (dual-stack) rather than an invalid host=''. Users can still pin a
specific host via platforms.webhook.extra.host.
Validated live on a Fly staging agent: with this default and no config
override, the adapter binds both v4 and v6 (127.0.0.1:8644 and [::1]:8644
both answer), and a public signed webhook POST through the router returns
202 (valid sig) / 401 (bad sig) instead of the router's 502.
Tests: new TestDualStackBind asserts the None default, config resolution
(missing/empty→None, pinned preserved), and a real dual-stack bind opens
both AF_INET and AF_INET6 listeners. Red-proof: these fail on the old
'0.0.0.0' default.
Follow-ups on the salvaged #20096 profile-routing feature:
- _profile_name_for_source now returns None unless gateway.multiplex_profiles
is on. Routing stamps source.profile, which namespaces session/batch keys,
but the profile-scoped agent run only activates under multiplexing — without
the gate, configured routes with multiplexing off split batch/session keys
into agent:<profile> while the agent still ran from agent:main.
- Widen the profile-aware _text_batch_key fix from Discord to every adapter
that builds batch keys via build_session_key (telegram, whatsapp, matrix,
feishu, wecom, weixin) — routing is platform-generic, so the batch-key
namespace fix must be too.
- Downgrade the no-route-matched log from INFO to DEBUG (fired on every
unrouted inbound message).
- GatewayConfig.to_dict(): serialize profile_routes as plain dicts
(ProfileRoute dataclasses are not JSON-safe).
- Docs: correct the 'independent of multiplexing' claim in
docs/profile-routing.md (routing requires multiplexing), fix the
platform-only specificity row (0, not 1), and document profile_routes in
website/docs/user-guide/multi-profile-gateways.md.
- Tests: pin the multiplex gate (routes ignored when off, active when on,
build_source end-to-end stays in agent:main when off).
Addresses hermes-sweeper review on #20096.
Problem 1 (profile_routing.py): route matching returned True on a chat_id
hit before the guild_id constraint was consulted, so a route declaring both
guild_id and chat_id matched on chat_id alone. Restored conjunctive (AND)
semantics — every declared discriminator must hold; hierarchical parent_chat_id
matching is preserved. Added a regression test for the guild+chat case.
Problem 2 (base.py / run.py): gateway_runner was injected only when an adapter
pre-declared the attribute, and only Discord did — so build_source never called
_profile_name_for_source for Telegram/Feishu/Slack/etc., despite the
platform-generic claim. Declared gateway_runner on BasePlatformAdapter and made
the plugin-registry injection unconditional, so profile routing now reaches
every platform. Added non-Discord (Telegram) resolution coverage and an
injection-inheritance test.
Also adds docs/profile-routing.md documenting gateway.profile_routes
(matching rules, specificity, profile isolation) — requested in review.

Adds gateway.profile_routes config that routes specific Discord
guilds/channels/threads (and other platforms) to different profiles.
The routing engine uses hierarchical specificity matching
(thread > channel > guild) with bounded LRU caching for forum post
resolution.
Routing result is stamped on source.profile by BasePlatformAdapter
.build_source() at inbound time. When gateway.multiplex_profiles is on,
the existing _profile_runtime_scope machinery picks up source.profile
and runs the whole turn inside the profile's HERMES_HOME — so memory,
skills, config, and secrets all resolve to that profile automatically.
No new isolation code is added; this PR only adds the routing decision
layer on top of the existing multiplexing infrastructure.
Configuration:
gateway:
multiplex_profiles: true
profile_routes:
- name: server-default
platform: discord
guild_id: "GUILD_ID"
profile: server-profile
- name: special-channel
platform: discord
guild_id: "GUILD_ID"
chat_id: "CHANNEL_ID"
profile: channel-profile
When multiplex_profiles is off, profile_routes is ignored (no behavior
change for single-profile gateways).
Tests: 29 unit tests covering specificity scoring, hierarchical
matching, path-traversal validation, and config parsing.

Reserve API requests before their first await, include every drain-owned work type in runtime status, and pause local cron dispatch while a gateway drain is active.
Closes#63529
Root cause: GatewayRunner._drain_active_agents only waited on
_running_agents + cron in-flight counts. Desktop/API sessions are
tracked solely inside APIServerAdapter (_inflight_agent_runs +
_active_run_agents), so stop/restart logged active_at_start=0 and
systemd SIGKILL'd mid-tool work.
Fix: APIServerAdapter.active_agent_work_count() plus
GatewayRunner._active_api_run_count() folded into the drain wait,
status updates, timeout result, and shutdown logs — same pattern as
_active_cron_job_count for #60432.
Verification: pytest tests/gateway/test_api_server_active_work_drain.py
tests/gateway/test_cron_active_work_drain.py -q → 19 passed
The base adapter's signature was updated to include
, which the reconnect watcher passes as
during reconnection. All other platform adapters were
updated, but QQAdapter was missed, causing:
TypeError: QQAdapter.connect() got an unexpected keyword argument 'is_reconnect'
This leads to an infinite retry loop since every reconnect attempt fails
immediately with the same TypeError.
Fix: add to QQAdapter.connect()'s signature.
QQBot has no server-side update queue, so the flag is accepted only for
interface conformance.
Test: new test_connect_accepts_is_reconnect_param verifies both
adapter.connect() and adapter.connect(is_reconnect=True) succeed without
raising.
- run_route_script shells out with subprocess.run (up to 30s timeout); wrap

Follow-up to the salvaged #54944: before this, aiohttp's implicit 1 MiB
default client_max_size tripped BEFORE the intended 3 MB Meta cap could
apply on read() paths — the explicit value makes the documented limit
real while the bounded reader keeps chunked bodies from buffering past
3 MB (#58536/#58902/#59180 pattern).
Sibling sweep from the #58902 raft review found aiohttp servers still
running on the implicit 1 MiB default with no explicit body cap:
- bluebubbles webhook (127.0.0.1): 1 MiB explicit cap — events are small
JSON/form payloads; attachments arrive via the REST API
- teams Bot Framework listener (0.0.0.0 bind — most exposed): 1 MiB cap;
activities are JSON well under that
- hermes proxy server: 10 MB cap mirroring api_server's MAX_REQUEST_BYTES
(chat-completion payloads can be large, but must stay bounded)
client_max_size bounds every read path including chunked transfer-encoding
requests that carry no Content-Length (#58536/#58902 pattern).
Deliberately excluded: feishu, whatsapp_cloud, sms, line, wecom, msgraph —
open contributor PRs (#54938, #54944, #54620, #54931, #54934, #25296)
already cover those; reviewing them separately preserves their credit.
3 regression tests pin the wiring.

No string content or live placeholder altered.
The unreadable-config-overwrite bug (an existing config.yaml that reads as
{} on a permission/IO error gets replaced with only defaults or the edited
section) is not limited to save_config / config set / auth. The same
read-then-atomic_yaml_write pattern lives at ~7 other independent write
sites that don't route through those functions:
- gateway/slash_commands.py: _save_config_key, memory/skills write_approval
toggles, tool_progress toggle, runtime_footer toggle, personality set
- hermes_cli/doctor.py --fix (stale root-key migration)
- gateway/platforms/yuanbao.py auto-sethome
- plugins/platforms/telegram/adapter.py topic thread_id persistence
- tui_gateway/server.py _save_cfg
- agent/onboarding.py mark_seen
Rather than sprinkle require_readable_config_before_write() at each site,
add a single fail-closed chokepoint, atomic_config_write(), that runs the
guard then delegates to atomic_yaml_write, and route every config.yaml
write through it. Root cause remains that read_raw_config() can't tell an
absent file from an unreadable one (returns {} for both) — read-only
callers correctly stay fail-open, but any full-file replacement now fails
closed in one enforced place instead of relying on each caller to remember
the guard.
save_config / set_config_value / auth keep the contributor's original
guard calls (their commit); this commit widens the fix to the sibling
call paths and adds a regression test on the chokepoint (fails closed on
unreadable existing file + still creates a genuinely absent file).

Follow-ups for salvaged #58461.
The Cloud setup wizard and docs tell operators to set
WHATSAPP_CLOUD_ALLOWED_USERS (and WHATSAPP_CLOUD_ALLOW_ALL_USERS), but the
adapter DM intake gate only read WHATSAPP_CLOUD_ALLOW_FROM + WHATSAPP_CLOUD_DM_POLICY
(default open, opted-in only via GATEWAY_/WHATSAPP_ALLOW_ALL_USERS). So an
allowlist set via the documented var silently dropped every inbound
(_should_process_message -> None -> HTTP 200, no dispatch, no log line).
- _allow_from also reads WHATSAPP_CLOUD_ALLOWED_USERS
- dm_policy defaults to allowlist when an allowlist is present (else open)
- _open_dm_opted_in() also honors WHATSAPP_CLOUD_ALLOW_ALL_USERS
Explicit DM_POLICY / ALLOW_FROM still win -> backward compatible.
_do_reconnect() succeeded but never called
YuanbaoAdapter.set_active(adapter), leaving get_active()
permanently returning None after any WS disconnect/reconnect
cycle. This caused cron delivery to silently fail because
_send_yuanbao() checks get_active_adapter() and gives up
immediately when it returns None.
Fix: call set_active(adapter) after successful reconnect,
matching the pattern in connect().
Fixes#58363
api_server already caps every read via client_max_size (chunked
included), but when the limit tripped mid-read the handler's broad JSON
except turned it into 400 'Invalid JSON'. Catch
HTTPRequestEntityTooLarge in body_limit_middleware and return the
OpenAI-style 413.
Status-code polish extracted from PR #3949 by @Gutslabs — the PR's core
client_max_size change already exists on main.
The webhook adapter enforced max_body_bytes only via the Content-Length
header; a Transfer-Encoding: chunked request (content_length=None) or a
spoofed small Content-Length bypassed the cap entirely and read the full
body (bounded only by aiohttp's implicit 1 MiB default, above any
operator-configured smaller limit).
- web.Application(client_max_size=max_body_bytes): aiohttp enforces the
cap on every read path, chunked included
- catch HTTPRequestEntityTooLarge -> 413 (was swallowed into generic 400)
- post-read length re-check as defense in depth
- chunked-upload regression test
Manual port of PR #3955 by @Gutslabs onto current main (handler had
been restructured since); authorship preserved.
_resolve_media_to_data_urls's ad-hoc _MEDIA_TAG_RE matched any bare
token after MEDIA: (no absolute-path anchor) and read the resolved
path directly with no denylist. A relative/traversal path like
MEDIA:../../../../etc/passwd.png slipped through, and any image-
suffixed file the process could read (including under ~/.ssh, ~/.aws,
etc.) was base64-inlined into the API response if its path merely
appeared in the model's own final reply text.
Every other platform adapter's MEDIA: handling already goes through
two shared primitives in gateway/platforms/base.py:
- MEDIA_TAG_CLEANUP_RE, which anchors the path to ~/, /, or a
Windows drive letter plus a known deliverable extension.
- validate_media_delivery_path, which resolves symlinks and rejects
paths under the credential/system-path denylist.
Reuse both here instead of the local unanchored pattern and naive
Path().expanduser() resolution.
The merged webhook session-close fix (#57370, salvaging #57322) wrapped
handle_message in a try/finally — but BasePlatformAdapter.handle_message
is fire-and-forget: it spawns _process_message_background and returns
before the agent run starts. The finally-close therefore ran BEFORE
get_or_create_session created the session row, found no session_id, and
silently no-op'd — the ghost-session leak persisted on the real path.
(The shipped test masked this by stubbing handle_message with a fake
that created the row synchronously.)
Move the close to an on_processing_complete override — the lifecycle
hook the base class fires at the TRUE end of the run, on the success,
failure, and cancellation paths alike. Empirically verified through the
real fire-and-forget pipeline: before, ended_at stayed NULL; after,
ended_at is set with end_reason=webhook_complete and the row is
prunable.
Tests now stub only the runner-side _message_handler (the seam the live
gateway injects) so handle_message / _process_message_background /
on_processing_complete all run for real; adds an AsyncSessionDB-facade
coverage test for the coroutine-await branch.
Replace the webhook delivery-close path's direct reach into private
SessionStore._entries (which also bypassed the store lock) with a public,
lock-held peek_session_id(session_key) accessor. Mirrors the existing
lookup_by_session_id inverse helper. Keeps a getattr fallback for older
stores / test doubles. Adds a unit test for the accessor.
Webhook deliveries created a unique one-shot session (delivery_id baked into
the session key at gateway/platforms/webhook.py:668) but the adapter fired
handle_message via asyncio.create_task WITHOUT ever ending the session
(webhook.py:713, pre-fix). Nothing else closes it: the gateway caches/expires
the agent per session_key but never calls end_session for the webhook path,
and _end_session_on_close teardown doesn't run for these fire-and-forget tasks.
SessionDB.prune_sessions (hermes_state.py:4965) only deletes rows WHERE
ended_at IS NOT NULL. So every webhook session stayed with ended_at NULL ->
unprunable -> unbounded state.db growth. This was the primary driver of the
SQLite lock-contention gateway outage.
Fix: wrap the delivery in _run_delivery_and_close, which awaits
handle_message and then (in finally, so failures still reap) calls
_end_webhook_session -> SessionDB.end_session(session_id, 'webhook_complete').
This mirrors how cron closes its session with 'cron_complete'
(cron/scheduler.py:3065). end_session is first-reason-wins and no-ops on an
already-ended row, so it never clobbers a compression/agent_close reason.
Adds tests/gateway/test_webhook_session_close.py asserting the invariant
(a completed webhook session has ended_at set + is prunable), including the
error-path case, against a real SessionStore + SessionDB.
Adds a no-code routing layer to the OpenAI-compatible API server so one
Hermes deployment can map different API clients to different
model/provider backends. Clients pick a backend by sending a configured
alias as the OpenAI 'model' field; unmatched values fall back to the
global model. Configured aliases are listed by GET /v1/models.
Precedence (highest first): session /model override > model_routes
route > global config. Route provider credentials resolve through
_resolve_runtime_agent_kwargs_for_provider (same seam as
channel_overrides); per-route api_key/base_url are upstream provider
credential overrides — never caller auth, never logged.
Salvaged and rebased from PR #3176 by @Mibayy onto current main.
Salvage of the surviving piece of #2696 by @tarunravi. The PR's other two
changes (tool progress streaming, SSE None-sentinel fix) were independently
superseded on main by the structured hermes.tool.progress SSE events and the
rewritten queue-drain loop.
Remote OpenAI-compatible frontends can't read server-local file paths, so
MEDIA:<path> tags (browser screenshots, generated images) were dead text.
_resolve_media_to_data_urls() now inlines small (<=5MB) local images as
markdown data URLs across all four response surfaces: chat completions
(non-streaming), session chat, session chat stream final event, and the
Responses API. Non-image, missing, or oversized paths pass through
untouched.
/health/detailed leaked runtime state (gateway state, connected
platforms, active-agent counts, PID, exit reason) with no auth. Gate it
behind the same Bearer auth as other API routes; plain /health stays
open for liveness probes.
Also refuse to start on a placeholder/too-short (<16 char) API_SERVER_KEY
regardless of bind address — a guessable key on a terminal-capable
endpoint is RCE-adjacent even on loopback, since any local process can
reach it. The required-key check was already unconditional; this extends
the strength floor to loopback binds too. Startup guards are hoisted
above app/background-task creation so a rejected start leaves no partial
state.

Aligns runtime behaviour with SECURITY.md 2.6: externally reachable
messaging adapters must fail closed unless access is explicitly
configured. Closes the confirmed multiplex authorization bypass a
secondary profile's open dm/group policy no longer inherits the default
profile's allowlist trust.
- Own-policy adapters (WhatsApp, WeCom, Weixin, QQBot, Yuanbao) default
dm_policy/group_policy to pairing/allowlist instead of open; open now
requires an explicit GATEWAY_ALLOW_ALL_USERS or per-platform allow-all.
- Startup guard (_own_policy_open_startup_violation) refuses to boot when
an enabled adapter is open without the allow-all opt-in; the guard now
runs for every secondary profile in multiplex mode too.
- Profile-aware own-policy authorization: _authorization_adapter /
_adapter_for_source resolve the live adapter via SessionSource.profile,
so _is_user_authorized and the ingress/pairing/busy/queue paths read the
originating profile's adapter policy, not the default profile's.
- Fail-closed intake for Email, Feishu P2P, and Discord (blank-principal
denial, empty-allowlist deny, missing-interaction.user deny).
Salvaged from #44073 (external-surface hardening), split into a focused
gateway-authz PR per maintainer request. Follow-up fix by Hermes Agent:
the Discord slash-auth channel bypass now matches DISCORD_ALLOWED_CHANNELS
by the same name-inclusive keys (id + name + #name + parent) the on_message
scope gate uses, so a name-form channel allowlist authorizes slash
interactions consistently (was id-only, breaking #name matching).
