Reverts the beta gating from 34d7d3f. The Hermes Cloud ModeCard in
Settings → Gateway now renders unconditionally alongside Local and Remote;
no BETA env var is consulted.
Not a clean `git revert`: commit 1b54d38 (the org-persist / stale-closure
fix) landed after the beta commit and edited the same useState block in
gateway-settings.tsx, so the revert conflicted there. Resolved by keeping
1b54d38's cloudOrgRef/setCloudOrg wrapper and dropping only the
cloudBetaEnabled state + its betaEnabled() useEffect. Everything else
(the sm:grid-cols-3 grid, the unconditional ModeCard, main.cjs/preload.cjs/
global.d.ts beta IPC) reverted automatically.
- main.cjs: drop betaFeaturesEnabled() + hermes☁️beta-enabled IPC
- preload.cjs / global.d.ts: drop the cloud.betaEnabled() bridge + type
- gateway-settings.tsx: drop the beta fetch/state; ModeCard renders
unconditionally; grid back to sm:grid-cols-3
No test referenced the flag, so no test fallout. tsc clean; eslint clean on
all touched files.
Three fixes from live testing the org persist/restore flow:
1. Org not persisting (stale closure). discoverCloud() resolves the org
asynchronously from the NAS response and setCloudOrg() is a React state
update, but connectCloudAgent read the cloudOrg value captured in its render
closure — often still null when the user clicked Connect in the same tick, so
no org was saved. Mirror the org into a ref (cloudOrgRef) updated
synchronously alongside state; connect reads cloudOrgRef.current.
2. Cloud connection lingered after switching away. coerceDesktopConnectionConfig
inherits existingBlock.url across mode switches (correct for remote↔local),
so switching cloud→local/remote kept the cloud instance URL in the remote
block — re-selecting Cloud then looked 'already connected' with no way to
re-pick. Added a leavingCloud rule: when the saved block was cloud and the new
mode isn't cloud, start from an empty block (drop the cloud url/org/token),
cleanly unselecting the cloud gateway. remote↔local toggles still preserve a
real remote URL.
3. Change-org button vanished after restore-open. It was gated on
cloudOrgs.length > 1, but the restore path discovers straight into the saved
org and never populates cloudOrgs. Gate on cloudOrg being set instead, via a
new changeCloudOrg() that clears the org + agent list and re-discovers with no
org arg (multi-org → NAS 409 picker; single-org → auto-resolve back).
Depends on NAS #550 (echo resolved org), merged + live on prod (0dc86d0b).
tsc + eslint clean; 57 node --test + 16 vitest pass; all three verified live on
Ben's host (org persists + restores, cloud unselects on switch, Change-org shows
after reopen). The benign 'Session not found' 404 on backend switch is left as-is
(already handled by isSessionGoneError → fresh draft; dev-log noise only).
cloud-auto-discovery Phase 3/4 follow-up.
The Hermes Cloud ModeCard in Settings → Gateway now only appears when the BETA
env var is truthy (1/true/yes/on, case-insensitive); absent/empty/false/0 hides
it. While the feature is in beta, non-beta users see only Local + Remote.
- main.cjs: betaFeaturesEnabled() reads process.env.BETA; exposed via new IPC
hermes☁️beta-enabled (the sandboxed renderer can't read process.env, and
runtime IPC means the same build honors BETA per-launch with no rebuild).
- preload.cjs / global.d.ts: cloud.betaEnabled() bridge + type.
- gateway-settings.tsx: fetch the flag on mount (default false so it never
flashes in for non-beta users), conditionally render the Cloud ModeCard, and
flip the grid sm:grid-cols-3 → sm:grid-cols-2 when hidden.
Gates the SELECTOR only — an already-saved cloud connection keeps working if
BETA is later turned off; only newly selecting cloud is hidden.
tsc + eslint clean; 57 node --test + 16 vitest pass; env parsing unit-checked
across 9 cases; gate verified in the packaged bundle.
cloud-auto-discovery beta gating.
Settings → Gateway remembered 'cloud' mode but not WHICH org/instance, so
reopening dropped multi-org users back to the org picker, hiding the connected
agent (reported live).
- Persist a cloudOrg on the saved cloud connection (rides the remote block:
coerce reads input.cloudOrg / inherits saved; buildRemoteBlock + profile
sanitizer carry it; sanitize echoes it back as config.cloudOrg). Only for
mode:'cloud'; plain remote is unchanged. The instance was already persisted as
remoteUrl (the dashboardUrl).
- discoverCloudAgents now returns the org NAS echoes in the response
(trimCloudOrg), and the renderer records cloudOrg AUTHORITATIVELY from
result.org — so it's set even on single-membership auto-resolve where no
picker ran (the exact case that left the org unpersisted). Requires NAS #550
(echo resolved org in /api/agents); before that deploys, falls back to the
requested org.
- On open, the cloud-status effect seeds cloudOrg from the persisted
config.cloudOrg and discovers scoped to it, so Settings reopens straight into
that org's agent list instead of the picker.
- connectCloudAgent passes cloudOrg when saving so the choice sticks.
- The connected instance is highlighted (primary tint + ring) and shows a
'Connected' pill instead of a Connect button (compares saved remoteUrl to each
agent's dashboardUrl, normalized).
tsc + eslint clean; 57 node --test + 16 vitest pass. Connected-pill verified live;
org-restore pending NAS #550 deploy for the authoritative echo.
cloud-auto-discovery Phase 3/4 follow-up.
When Hermes Cloud discovery returns zero agents, the empty-state message now
renders 'Nous portal' as a hyperlink to https://portal.nousresearch.com/agents
(opened via the app's ExternalLink → shell.openExternal), so the user can jump
straight to creating an agent instead of finding the portal manually.
The cloudNoAgents i18n string becomes { before, linkText, after } (en + zh) so
each locale controls link placement; ja/zh-hant fall back to en via defineLocale.
No external-link icon on this inline link to keep the sentence clean.
tsc + eslint clean; link verified present in the packaged renderer bundle.
The silent per-agent sign-in (decisions.md Q5) was prompting a SECOND interactive
login after portal sign-in → org → dashboard selection (Ben's screencast). Root
cause: cloudAgentSilentSignIn → openOauthLoginWindow loaded the agent gateway's
/login, but /login is a PUBLIC route (dashboard-auth middleware allowlist), so the
gate's _auto_sso_response never runs there — it only fires on an unauthenticated
load of a PROTECTED page. The window therefore rendered the interactive
'Log in with X' chooser every time, instead of the silent 302 cascade. (Auto-SSO
is correctly configured on hosted agents: exactly one 'nous' session provider,
client_id agent:{id}, so it would have fired silently if triggered.)
Fix: openOauthLoginWindow(baseUrl, { silent }). The cascade passes silent:true,
which loads the PROTECTED root '/' instead of '/login'. The gate then runs
auto-SSO — single provider + a live partition portal session → 302 through
/auth/login → portal /oauth/authorize (auto-approves org members) → /auth/callback
sets the gateway session cookie with NO prompt. In silent mode the window also
starts HIDDEN and only reveals after 2.5s if the cascade hasn't completed
(graceful fallback to interactive, e.g. the portal session lapsed). The
interactive remote-gateway login (settings UI) keeps silent:false → /login
chooser, behavior unchanged.
Verified live end-to-end on Ben's host: portal sign-in → org picker → select agent
→ Connect now completes with no second login prompt.
cloud-auto-discovery Phase 3 follow-up (decisions.md Q9).
Two fixes surfaced by the first live end-to-end test of cloud sign-in (both
would have shipped broken — green units + code review did not catch them).
1. Portal session is PRIVY, not Hermes-gateway cookies (Q7). Phase 3 polled for
hermes_session_at/rt on the portal host, but the Nous portal (NAS) is a
Privy-authed Next.js app — it sets privy-token (which NAS auth() and the
/api/agents cookie path both read). The sign-in window therefore never
detected success and hung. Fix: cookiesHavePrivySession (privy-token + __Host/
__Secure/legacy privy-session variants) in connection-config.cjs, and
hasLivePortalSession now checks the Privy cookie on the portal host. The
per-agent silent cascade still uses the gateway-cookie check (each agent IS a
Hermes gateway).
2. Multi-org discovery needs an org picker (Q8). A portal session carries no org
pin, so a user in >1 org got a dead-end 403. Paired with NAS #545 (merged):
/api/agents now returns 409 org_selection_required + the user's org list, and
accepts a membership-validated ?org=. discoverCloudAgents(org) appends ?org=,
and on 409 returns { needsOrgSelection, orgs } instead of throwing; the cloud
panel shows a 'Choose an organization' picker, then re-runs discovery scoped
to the chosen org (with a 'Change org' affordance for multi-org users).
Also reverts the ERR_NETWORK_CHANGED retry helper from the prior commit: the
IPv6-churn aborts on Ben's Arch host are a host/network-layer issue, and a
client reload can't safely drive Privy's single-use-code redirect chain
(disable IPv6 for the session is the workaround). Kept out of this feature PR.
Tests: connection-config.test.cjs (57, +5 Privy-cookie cases, proven to fail
without the helper); boot-failure-reauth (16). tsc + eslint clean. Verified live
end-to-end against prod portal: sign-in → org picker → scoped agent list →
silent per-agent connect.
cloud-auto-discovery Phases 3+4 follow-up (decisions.md Q7, Q8).
Phase 4 of cloud-auto-discovery — the UI on top of the Phase 3 cloud plumbing.
Adds a third 'Hermes Cloud' ModeCard alongside Local/Remote in gateway-settings.
Selecting it reveals the cloud panel instead of the URL/token form:
- signed-out → 'Sign in to Hermes Cloud' (one portal login in the OAuth partition)
- signed-in → a discovered-agent picker (loading / empty / list states) with a
Refresh control. Selecting an agent drives the silent per-agent cascade
(cloud.agentSignIn) then applies a mode:'cloud' connection pointed at its
dashboardUrl — no second sign-in prompt.
Cloud auto-discovers on entering the mode when a portal session already exists.
Test/Save bottom-row actions are hidden in cloud mode (selection applies the
connection); the remote URL/token form is now gated to remote mode only.
Wires the renderer to the Phase 3 IPC (window.hermesDesktop.cloud.*). i18n
strings added to en + zh (full) and the Translations type; ja/zh-hant inherit via
defineLocale fallback. New 'Cloud' icon (IconCloud) exported from lib/icons.
Validated: tsc clean, eslint clean, vite renderer build succeeds, 52 electron +
16 vitest tests pass.
cloud-auto-discovery Phase 4.
Phase 3 (non-UI) of cloud-auto-discovery. Adds the 'cloud' connection mode and
the IPC plumbing for a single portal login that powers both agent discovery and
silent per-agent sign-in. The Phase 4 UI (cloud ModeCard + instance picker)
sits on top of these IPC methods.
Mode widening (Model A, decisions.md Q6): DesktopConnectionConfig.mode and
DesktopConnectionConfigInput.mode widen to 'local'|'remote'|'cloud'. A cloud
entry is a remote-shaped block (remoteUrl = the selected agent's dashboardUrl,
remoteAuthMode 'oauth') tagged mode 'cloud' so settings reopens into the cloud
picker. Every RESOLUTION site treats cloud as remote via the new
modeIsRemoteLike() helper (centralized in connection-config.cjs): readDesktop-
ConnectionConfig, sanitizeConnectionProfiles, sanitizeDesktopConnectionConfig,
coerceDesktopConnectionConfig, profileRemoteOverride, resolveRemoteBackend,
globalRemoteActive, testDesktopConnectionConfig, and isRemoteReauthFailure. The
live resolved HermesConnection.mode stays 'local'|'remote' — cloud never reaches
the boot path or the renderer remote-gating sites.
Cloud mechanics (main.cjs): one portal session in the persist:hermes-remote-oauth
partition does double duty — discoverCloudAgents() GETs {portal}/api/agents over
the partition-bound net (cookie-authed; NAS #542 accepts the cookie), and
cloudAgentSilentSignIn() opens a selected agent's /login in the same partition so
the portal's silent auto-approve 302s back with that agent's session cookie, no
second prompt. Portal base URL resolves via DEFAULT_NOUS_PORTAL_URL +
HERMES_PORTAL_BASE_URL/NOUS_PORTAL_BASE_URL overrides, mirroring the CLI.
IPC: hermes☁️{status,login,logout,discover,agent-sign-in} in main.cjs +
preload.cjs, typed in global.d.ts (DesktopCloudStatus/Agent/DiscoverResult/
AgentSignInResult).
Tests: modeIsRemoteLike + cloud profileRemoteOverride (node --test, 52 pass);
cloud reauth-failure cases (vitest, 16 pass). tsc clean; eslint clean. New tests
verified to fail without the source changes.
cloud-auto-discovery Phase 3 (non-discovery half + discovery/cascade plumbing).
Gateway half of relay-platform-parity Phase 2.5 (D-Q2.5). The relay wire's
platform-neutral scope discriminator is renamed guild_id → scope_id; this is the
hermes-agent side of the cross-repo wire-compatible migration.
- SessionSource: scope_id is canonical; guild_id kept as @deprecated alias.
__post_init__ mirrors the two so all existing SessionSource(guild_id=...)
constructors across native adapters keep working unchanged. to_dict dual-WRITES
scope_id+guild_id; from_dict dual-READS scope_id ?? guild_id.
- relay/adapter.py: capture + outbound metadata dual-read/write scope_id.
- relay/ws_transport.py: _frame_to_event dual-reads scope_id ?? guild_id.
- docs/relay-connector-contract.md: document scope_id (canonical) + guild_id
(deprecated alias) in the §3 SessionSource field table (conformance test).
250 relay+session+contract tests green. Solo lane (relay).
The self-hosted OIDC dashboard login rejected any http:// redirect_uri
whose host was not localhost/127.0.0.1, surfacing "redirect_uri may only use http:// for localhost/127.0.0.1" before reaching the IDP. This broke self-hosted dashboards reached over plain HTTP (including LAN IPs, internal hostnames, and reverse proxies that terminate TLS upstream).
#38827 already dropped this check from the nous provider, but the generic self-hosted provider copied the old localhost-only
branch and reintroduced the bug for HERMES_DASHBOARD_OIDC_ISSUER setups.
The IDP's own allowlist is authoritative on which redirect_uris are
permitted; this client-side _validate_redirect_uri is only a fast-fail for
obvious operator error and should not second-guess valid http:// deployments.
Fix: drop the localhost-only branch on the http scheme. Validation now enforces only that the scheme is http(s) and the path ends with
/auth/callback. Updated the docstring to explain the relaxed contract,
and added test_allows_http_with_arbitrary_host covering an internal
hostname and a LAN IP alongside the existing localhost case.
The topic-mode helpers (_telegram_topic_mode_enabled,
_recover_telegram_topic_thread_id, _record/_sync_telegram_topic_binding,
_is_telegram_topic_lane/_root_lobby, _normalize_source_for_session_key,
_telegram_topic_new_header, _schedule_telegram_topic_title_rename, and the
base.py _apply_topic_recovery hook) each run a synchronous SessionDB read or
write. They reach the event loop through async handlers, so a contended
state.db froze the loop the same way the handoff watcher did.
These helpers already run off-loop in the run_sync thread-pool closure, so
they are proven thread-safe there. Rather than colour them async, loop-side
callers now invoke them via asyncio.to_thread(...); the executor callers are
unchanged. Inside the helpers the SessionDB handle is unwrapped to the sync
door (getattr(db, '_db', db)) since they always run on a worker thread, and
AIAgent construction + query_session_listing are handed the sync SessionDB
directly. base.py wraps its single _apply_topic_recovery call in to_thread.
The guard is now alias-aware (catches db = getattr(self, '_session_db', None);
db.method(...)) and enforces the offload contract: the offloaded sync helpers
may never be called bare on the loop. Sibling test fixtures wrap their injected
SessionDB in AsyncSessionDB to match how the gateway holds it.
The migration's call-site sweep keyed on the literal self._session_db.
spelling and missed calls bound to a local first
(db = getattr(self, '_session_db', None); db.method(...)). Convert the
three in async contexts: get_telegram_topic_binding in the topic-rename
coroutine, and the two update_session_model sites on the model-switch path.
* fix(gateway): skip confirmed-dead delivery targets (deleted groups, blocked bots)
A deleted Telegram group, kicked/blocked bot, or deactivated user keeps
throwing Forbidden/not_found on every cron tick and fan-out delivery. Each
retry burns a send against the platform's flood-control envelope and spams
the logs, making the whole session feel broken even when the model call
completed.
Add a small persistent DeadTargetRegistry (per-profile JSON under
HERMES_HOME) that records a target the moment a send reports a whole-chat
death (forbidden / chat-level not_found), and have DeliveryRouter.deliver()
short-circuit it on subsequent attempts. Self-healing: any successful send
clears the flag, so a user re-adding the bot recovers with no manual cleanup.
Thread/topic-level not_found is NOT recorded (adapters already self-heal that
by retrying without reply_to). Transient/timeout errors are never marked dead.
* infographic: dead delivery target skipping
When a full-screen route overlay (settings/profiles/cron/agents/command-center) is up, the pet's walkable surface swaps to a single ledge at the overlay card's bottom edge — derived from OverlayView's shared inset, not measured — so it patrols there; closing the overlay restores the normal surfaces and it drops back down.
Walk speed is derived from the sprite's animation loop + on-screen size (one body-width per loop) instead of a fixed px/s, so it steps rather than glides; the pet also sinks a few px so its feet meet the surface instead of hovering.

usePetRoam re-measures ledges from the live DOM each beat and walks/hops/falls between them, driving DOM position imperatively (no per-frame re-render).
Opt-in $petRoam (localStorage), $petMotion (run/jump pose) and $petRoamDir (-1/0/1) feed the shared $petState only while the agent is at rest ($petAtRest), so a wander never overrides real activity.
Add a generic suppress_notification flag to the drain-request marker. When a
drain that ends in process exit (e.g. a NAS auto-update image migration on the
always-on Hermes Cloud fleet) is flagged, the gateway skips ONLY the
home-channel 'gateway shutting down' broadcast — the operator-flavoured ping
that would otherwise fire on every routine auto-update, dozens of times a day.
The per-active-session interrupt ping is ALWAYS kept: on a drained shutdown
it's empty by construction, and in the force-interrupt (deadline-exceeded) case
it carries the user-valuable 'your task was cut off, message me to resume' hint.
The gateway stays agnostic about WHY a drain is quiet (generic boolean, not a
kind enum); the policy of which drain causes set the flag lives in the caller
(NAS). Default-false so legacy/operator drains behave exactly as before. The
reader reuses the NS-570 epoch-staleness check so an orphaned marker on the
durable volume can never silence a fresh gateway's legitimate broadcast.
- drain_control.py: write_drain_request gains suppress_notification; new
drain_notification_suppressed() reader (current-epoch + truthy flag).
- web_server.py: /api/gateway/drain reads + echoes the flag.
- run.py: _notify_active_sessions_of_shutdown skips the home-channel loop only.
Tests prove: flag round-trips; home-channel suppressed when set, kept when
unset; active-session ping always fires; stale/legacy/corrupt markers never
suppress.
The Gateway item is the only statusbar entry with variant === 'menu'.
Since da73223f4 wrapped every render branch in `Tip`, the menu branch
nested `<DropdownMenu>` (a Radix Root that renders no DOM node) inside
`Tip`'s `<TooltipTrigger asChild>`. With no element to attach to, Radix
could never wire hover listeners, so the tooltip silently never showed.
`Tip` also can't be moved inside `DropdownMenuTrigger asChild` (the shape
proposed in #54859): it's a plain component, not a Slot-forwarding one, so
the trigger's injected ref/handlers would land on `TooltipContent` instead
of the button and break the menu's click + popper anchoring.
Fix by composing both trigger Slots directly onto a single <button>
(`TooltipTrigger asChild` over `DropdownMenuTrigger asChild`), the pattern
already used in profile-switcher.tsx, and skip the tooltip wrapper entirely
when the item has no title.
Supersedes #54859.

Subagent session pop-outs (`watch=1`) spectate a run driven elsewhere, so
editing/steering the transcript from there makes no sense. Gate the composer
and the user-bubble mutations on `isWatchWindow()`:
- hide the composer (folds into `showChatBar`)
- user prompts become a read-only button that toggles the 2-line clamp so long
prompts stay fully readable, instead of opening the edit composer
- drop the stop/restore actions and the checkpoint branch-picker
Keyed off the narrow `isWatchWindow()` (not `isSecondaryWindow()`), so the
new-session and cmd-click pop-outs are unaffected.
* feat(web_extract): truncate-and-store instead of LLM summarization
web_extract no longer runs an auxiliary LLM over scraped pages. The extract
backends (Firecrawl/Tavily/Exa/Parallel) already return clean, boilerplate-
stripped markdown, so we return it directly: pages within a char budget
(default 15000, web.extract_char_limit) come back whole; larger pages get a
head+tail window plus an explicit footer giving the stored full-text path and
the read_file call to page through the omitted middle. The full clean text is
written to cache/web (mounted read-only into remote backends like the other
cache dirs), so nothing is lost.
Inline base64 images are converted to [IMAGE: alt] placeholders (token bombs
dropped) while real http(s) image URLs are preserved as links so the agent can
still web_extract/vision_analyze them.
Removes process_content_with_llm + the chunked summarizer + check_auxiliary_model
+ _resolve_web_extract_auxiliary. context_references._default_url_fetcher is
updated to the truncate path and its stale data.documents shape read is fixed
to results (it was silently returning empty).
Live before/after eval (firecrawl, 4 URLs): 11.7x faster overall (176.6s ->
15.1s); 10-60x on large pages. Quality identical; findability 4/4 (answer
recoverable from stored full text on every truncated page). web_search is
unchanged.
No own scraper added; no changes to web_search.
* fix(web_extract): add char_limit to execute_code web_extract stub
The new web_extract char_limit param must appear in the code_execution_tool
_TOOL_STUBS signature (and doc line) or test_stubs_cover_all_schema_params
fails — the stub schema must cover every real schema param.
A manually-installed venv inside the cloned repo can be destroyed by the
agent running a relative-path command against its own checkout (rm -rf venv,
uv venv venv, etc.), silently wiping the running runtime mid-session. Moving
the canonical manual-install venv to ~/.hermes/venvs/hermes-dev means no
relative path from the agent's workspace resolves to its own runtime, making
the bug class impossible without any command-detection code.
Closes the root cause of #7779. The managed install.sh layout is unchanged.

NVIDIA integrate.api.nvidia.com models such as minimaxai/minimax-m3 can
return HTTP 200 with empty choices when max_tokens is omitted. Keep the
output cap on auxiliary chat-completions routes, matching the main NVIDIA
provider profile behavior.
The register path builds each profile-gateway slot in a sibling staging
dir under /run/service (the scandir s6-svscan watches), then atomically
renames it to the live gateway-<profile> name. The staging dir was named
gateway-<profile>.tmp — a NON-dotfile — so a concurrent `s6-svscanctl -a`
rescan (fired by the cont-init reconciler registering gateway-default, or
by a sibling register) would supervise the half-built slot the moment it
had a valid type/run: s6-supervise spawns AS ROOT and mkdirs supervise/
root-owned 0700, then the in-flight _seed_supervise_skeleton early-returns
on the now-existing supervise/ and the next `mkdir supervise/event` hits
PermissionError.
That is the arm64-only CI flake on
test_s6_unregister_removes_service_dir_in_live_container
(PermissionError: /run/service/gateway-phase3test.tmp/supervise/event) —
arm64-only because the native-arm runner's wider scheduling jitter lets
the rescan land inside the ~ms seed window; amd64 ran 30/30 clean.
Fix: dot-prefix the staging dir (.gateway-<profile>.tmp) in both register
paths (S6ServiceManager.register_profile_gateway and
container_boot._register_service). s6-svscan skips any scandir entry whose
name begins with '.', so the half-built slot can never be supervised
mid-build. The atomic rename to the dotless live name is unchanged.
Verified on a real s6 image (amd64): a non-dotted staging dir is picked up
by an svscanctl -a rescan (SUPERVISED owner=root) while a dot-prefixed one
is ignored (NOT-SUPERVISED). Added a docker-harness regression test that
asserts both, plus a unit test that the staging dir is dot-prefixed.
