Add authenticated GET /api/model/options to the gateway API server,
sharing the dashboard/TUI picker payload builder so external clients
can sync to the user's configured Hermes provider catalog instead of
scraping the single OpenAI-compatible /v1/models alias.
- new shared hermes_cli.inventory.build_model_options_payload() wraps
build_models_payload with the stable picker shape and safe
custom-provider probe policy (probe current only on normal open,
probe all + cache bust on explicit refresh)
- dashboard web_server and TUI gateway model.options refactored onto
the shared builder; dashboard build moved off the event loop via
run_in_threadpool
- capabilities endpoint advertises model_options
- docs for both API server and programmatic integration

Follow-up to salvaged PR #70549:
- Replace fragile 'or' assertions with single precise checks that catch
partial-rewrite regressions (would have masked a missing closing brace)
- Add test_pty_path_uses_rewritten_command covering the PTY spawn path
that was modified but previously untested
A session pinned to a named custom provider could silently reroute to the
user's default provider on resume/rebuild. Session rows persist the RESOLVED
provider — bare "custom" for every named providers:/custom_providers: entry —
and when no base_url survived in model_config, the existing heal
(canonical_custom_identity) had only the config.model.provider fallback left.
For users whose global default is a BUILT-IN provider (e.g. nous) that tier
cannot fire, so the bare provider was dropped, resume fell back to the default
provider with the session's custom model name, and the default endpoint 404'd
with "Model '<x>' not found. The requested model does not exist in our
configuration or OpenRouter catalog." Re-selecting via /model fixed it until
the next resume — the reported symptom.
Add a model-name recovery tier between the base_url reverse-lookup and the
config fallback: find_custom_provider_identity_by_model() maps the stored
model back to the entry that serves it (model/default_model/models catalog,
dict and legacy list shapes). The session row always stores the model, so the
entry identity survives even when the row has no base_url AND the global
default points elsewhere.
All five bare-custom heal sites in tui_gateway/server.py now pass the model:
_ensure_session_db_row, _stored_session_runtime_overrides,
_runtime_model_config, _make_agent, and _model_picker_context.
Issue #68915: when the agent runs a compound command with trailing & (e.g.
`cd /app && node server.js &`), bash parses it as `(A && B) &` — a subshell
that holds the stdout pipe open forever when B is a long-running server.
The existing _rewrite_compound_background in terminal_tool.py correctly
rewrites this to `A && { B & }` to avoid the subshell fork, but it was only
applied in the foreground execute() path (tools/environments/base.py).
The background spawn_local() path bypasses base.py entirely and passed the
raw command directly to Popen/PTY, leaving the deadlock unmitigated.
Fix: apply _rewrite_compound_background in spawn_local() before the command
is passed to Popen or PTY spawn. Uses a lazy import to avoid circular
dependency (terminal_tool imports process_registry).
- PTY spawn path: now uses safe_command (rewritten)
- Popen spawn path: now uses safe_command (rewritten)
- Session.command still stores the original (unrewritten) command for display
- Simple `cmd &` is left unchanged (no subshell bug)
Tests: 4 regression tests verifying (1) compound is rewritten, (2) simple bg
is preserved, (3) multi-line compounds are rewritten, (4) session.command
stores original.
Follow-up on the salvaged #68469 commit:
- Literal-IP hostnames never take the proxy DNS-delegation path (a
getaddrinfo failure on a literal IP is not a proxy-environment
symptom, and IPs need no DNS) — keeps the private-IP/metadata floor
intact under proxy env vars.
- Adds TestProxyEnvironmentDnsDelegation: delegation fires only for
hostnames, metadata hostname/IP floor holds, DNS-success path
unchanged, empty proxy var ignored.
- Guards the three pre-existing DNS-failure tests against ambient
proxy env vars so they don't flake on developer machines.
Track the selected credential by stable pool entry ID so token refreshes and shared cursor movement cannot detach failures from the entry that issued them. Stop unmatched single-entry pools from reporting a no-op rotation as successful recovery.

Follow-ups on the salvaged #54426 routing contract:
- Bare `model` without `provider` on the OpenAI-compatible endpoints
(/v1/chat/completions, /v1/responses) is now opt-in via
gateway.platforms.api_server.direct_model_requests (default off) —
generic OpenAI clients hardcode model names ('gpt-4o', ...) and
existing deployments rely on those falling back to the gateway
default. Explicit `provider` requests and the Hermes-native
session-chat + /v1/runs surfaces are always honored.
Idea credit: PR #22825 by @mssteuer.
- A model_routes alias with no `model` key can no longer leak the
alias string as the executing model name (defensive; parse-time
validation already drops such routes).
- Fix mis-indented _run_agent call args in _handle_session_chat_stream.
- Docs: document the opt-in flag.
Carry model, provider, and model_options through the API server's
execution surfaces (session chat, Chat Completions, Responses, /v1/runs)
without mutating global configuration. Precedence: session /model
override -> model_routes alias -> direct request selection -> global
defaults. Conflicting route/provider mixes fail closed with 400.
model_options stays request-scoped regardless of which selection wins.

test_docker_network_config.py landed on main after the #58489 revert and
stubbed docker ps with the 2-field ID\tState format. The re-landed
egress-aware reuse probe requests ID\tState\tEgressLabel when egress is
off, so the fake line failed to parse and the reuse path never fired.
Fixture-only change; production behavior is unchanged.
The gateway startup maintenance block gained a maybe_auto_archive call in
the same provably-off-loop __init__ site as maybe_auto_prune_and_vacuum;
bump the reviewed sync-escape count from 3 to 4.
New sessions.auto_archive / auto_archive_days config: soft-hide (never
delete) sessions with no activity for N days, aging on last activity
rather than creation so an old-but-active chat is spared. Sweeps are
throttled through state_meta and fire from CLI startup, gateway startup
+ hourly housekeeping, and the serve/dashboard backend (opportunistic
on session list + an hourly lifespan ticker), so every surface honours
one setting.
A new pinned column (declaratively migrated) exempts sessions from the
sweep; PATCH /api/sessions/{id} accepts pinned and flips the whole
compression lineage as a unit, mirroring set_session_archived.
session.branch wrote the child ROW into the parent's profile db but
built the live agent with the launch defaults: _make_agent fell back to
_get_db() and no HERMES_HOME override was active. The branched agent's
own message flushes — and any later compression rotation it performed —
therefore landed back on the launch profile, splitting the lineage one
turn after the branch. Mirror session.create/resume: open the parent
profile's SessionDB for the agent and hold the home override across the
build, so config/skills/memory resolve to the profile too.
Spotted in #70605's sibling implementation of the same fix.

The blanket MAX_DESCRIPTION_LENGTH=1024->60 change is narrowed:
create-time validation now rejects new skills whose description
exceeds SKILL_PROMPT_DESC_LIMIT (60) with actionable guidance, while
edit/patch paths stay permissive (warning via system_prompt_preview)
so existing over-limit skills remain maintainable. Runtime display
truncation in skills_tool is left at 1024 (display behavior is a
separate concern from authoring validation).
Boundary tests: 60 accepted, 61 rejected at create; edit/patch on
over-budget skills still succeed.
RFC 8628 §3.2 makes the device-authorization `interval` optional with a
client-side default of 5 seconds. request_device_code required it, so a
compliant AS that omitted it hit the malformed-response path and the flow
could never complete. Fall back to 5s and cover it with a regression test.

Adds a device authorization grant flow alongside the existing loopback
OAuth flow, so `hermes setup` can connect to Honcho cloud from SSH and
other no-browser environments.
- oauth.py: new HTTP seams — _http_post_form_status (non-raising, since
RFC 8628 polling reads the OAuth error off a 400) and _http_get_json
for the RFC 8414 metadata probe
- oauth_flow.py: DeviceCode, request_device_code, poll_for_token with
slow_down backoff (+5s, capped at 60s) bounded by expires_in, typed
errors (AccessDenied, DeviceCodeExpired, AuthorizationTimeout), and
supports_device_login (fail-closed metadata gate); device flow ends in
the same install_grant tail as loopback so refresh/status work
unchanged
- oauth_flow.py: loopback callback now serves a "sign-in was not
completed" page on consent cancel instead of the success page
- cli.py: cloud menu offers oauth / device / apikey; the device option
only appears when the host advertises the grant, and becomes the
default when no browser is detected
- 18 new tests covering the full flow against a local fake AS, backoff
schedule, error mapping, deadline bound, metadata gate, and wizard
branches

Under multiplex_profiles, the gateway starts a single InProcessCronScheduler
bound to the process-global HERMES_HOME (the default profile's home), so
only that profile's cron/jobs.json is ticked. A job registered from a
secondary-profile session lands in <profile>/cron/jobs.json, reports a valid
next_run_at — and never fires.
Changes:
1. cron/scheduler_provider.py — InProcessCronScheduler.start() now accepts
an optional profile_homes kwarg (list of (name, Path) tuples). When set,
_start_multiplex() iterates tick() over each profile home using
use_cron_store(), so every served profile's cron store is ticked on
every tick cycle. Heartbeats and interrupted-execution recovery are also
scoped per profile via use_cron_store().
2. gateway/run.py — start_gateway() now resolves profiles_to_serve(multiplex=True)
when multiplex_profiles is on and passes them to the cron scheduler as
profile_homes. Only applies to InProcessCronScheduler (the built-in);
external providers are unchanged.
3. cron/jobs.py — record_ticker_heartbeat(), get_ticker_heartbeat_age(), and
get_ticker_success_age() now resolve paths via _current_cron_store()
instead of module-level TICKER_HEARTBEAT_FILE / TICKER_SUCCESS_FILE
constants. This makes heartbeats correctly scoped per profile, so
'hermes cron status' reflects liveness for every profile independently
under multiplex_profiles.
4. tests/cron/test_scheduler_provider.py — two new tests:
- test_multiplex_ticker_ticks_each_profile_once: verifies tick() is called
once per profile per tick cycle.
- test_multiplex_heartbeat_scoped_per_profile: verifies heartbeat files
are written to each profile's cron store.
Widens the salvaged .env injection fix (#50315) to the sibling site it
missed: hermes_cli/memory_setup.py::_write_env_vars is the near-identical
core writer the openviking plugin's copy was forked from, is fed directly
by interactive _prompt() (pasted API keys), and is reused by other memory
plugins (e.g. supermemory imports it). A pasted secret with an embedded
CR/LF injected an arbitrary extra KEY=VALUE line on the next read.
Same _env_line_safe() treatment as the plugin writer (strip every
str.splitlines() separator + NUL), matching config.save_env_value's
existing newline strip. Mutation-checked: reverting the sanitizer makes
the new regression tests fail.
Follow-up hardening on the salvaged _ensure_client() (#21130 fix):
- Failed-config cooldown: after a refresh attempt fails for a given
resolved config, skip re-probing for 30s. Previously every provider
access against a down endpoint paid a 3s health probe under
_client_refresh_lock and emitted a warning (2+ per turn, some on
user-facing threads: prefetch, tool calls, session end). Retries
still happen after the cooldown or immediately when config changes,
and the log message now says so instead of the false 'disabled until
config changes'.
- Atomic connection snapshot: _conn_snapshot (5-tuple, single
assignment) is published only after a health check passes.
_new_client() and on_memory_write's writer read it as one load, so
background writers can no longer observe a torn mix of old/new
identity fields mid-refresh or target an endpoint that never passed
health. Field writes in _ensure_client_locked keep tracking the
attempted config for the unchanged-config dedupe.
- _env_refresh_enabled moves to the top of initialize(): an exception
mid-initialize (swallowed by MemoryManager) can no longer leave the
provider silently stuck in never-refresh mode.
- _search_prefetch_context reuses _new_client() and degrades to ''
on construction failure instead of propagating.
Mutation-checked: neutering the cooldown or publishing the snapshot on
failed health makes the new regression tests fail.
Avoid spawning multiple local OpenViking server processes while a runtime autostart waiter is already active. Remote endpoints still retry on later accesses because they do not install a local waiter.
Route refreshed unreachable local OpenViking configs through the existing runtime recovery path so /reload can attach to a locally starting server instead of disabling memory until restart.
(cherry picked from commit 040e18ad90)
The _needs_trusted_identity_retry method was hard-coding specific
server-side error strings to detect when a request failed due to
missing X-OpenViking-Account / X-OpenViking-User headers. Each new
server-side error variant required another string added to the client.
Replace the string enumeration with a structural match: the error
message mentions one of the tenant headers AND the HTTP status is 400.
This covers all current error variants:
- "Trusted mode requests must include X-OpenViking-Account and User"
- "ROOT requests to tenant-scoped APIs must include X-OpenViking-Account"
- "Trusted mode requests must include X-OpenViking-Account."
- "Trusted mode requests must include X-OpenViking-User."
The 400 status guard avoids false-positives on 403 errors such as
"USER API keys cannot override X-OpenViking-User", which must not
trigger a retry.
All 176 existing tests pass.
(cherry picked from commit 5a24d6766c)
`OpenVikingMemoryProvider.shutdown()` joins in-flight writers, deferred-commit
threads, and prefetch threads, but not `_runtime_start_thread` — the tracked
`daemon=True` waiter that runs `_finish_runtime_openviking_start`, which blocks
on network health probes (`_wait_for_openviking_health` polling + a
`_VikingClient.health()` request).
If the local OpenViking runtime is slow or unreachable, that waiter can still
be blocked in network I/O at interpreter exit. CPython then forcibly kills it
during `Py_FinalizeEx` (`PyThread_exit_thread` -> `__pthread_unwind` ->
`abort()`), producing SIGABRT (exit 134) with no traceback — the same daemon-
thread-at-exit failure class fixed for the Honcho provider.
Fix:
- `shutdown()` now joins `_runtime_start_thread` (timeout-bounded) alongside the
other tracked threads.
- `_wait_for_openviking_health()` gains a `should_stop` callback; the waiter
passes `lambda: self._shutting_down` so the poll loop bails out promptly once
`shutdown()` flips the flag, instead of lingering up to the 60s autostart
timeout and timing out the join (which would leave the thread alive).
- Add tests/plugins/memory/test_openviking_shutdown.py covering the short-circuit
and the shutdown-joins-runtime-thread behaviour.
(cherry picked from commit 5471ec7021)
initialize() snapshots OPENVIKING_* into the provider once, so /reload
(which only updates os.environ) leaves viking_* tools running against
stale auth — users have to restart hermes to pick up keys added to
~/.hermes/.env after startup.
Add _ensure_client(), which re-resolves the connection settings via the
same _resolve_connection_settings/_load_hermes_openviking_config path
initialize() uses and rebuilds + health-checks the client only when an
OPENVIKING_* value actually changed; otherwise it reuses the cached
client so the hot path stays at one dict comparison with no network
calls. Every `if not self._client:` guard in system_prompt_block,
queue_prefetch, sync_turn, on_session_end, on_memory_write and
handle_tool_call now goes through it.
Refreshing is gated behind a flag set at the end of initialize() so the
baseline is established before any env re-resolution happens — callers
that wire up a client directly keep the existing client untouched.
Refs #21130
(cherry picked from commit b694d21b7c)
`_write_env_vars` in the OpenViking memory provider interpolates each
secret straight into a `KEY=VALUE` line, but the values only ever pass
through `_clean_config_value`, whose `value.strip()` trims surrounding
whitespace and leaves internal CR/LF intact. Because the file is strictly
line-oriented and is re-read via `read_text().splitlines()`, a value that
carries an embedded newline spills onto a second physical line, and the
tail is re-parsed as an independent `KEY=VALUE` entry on the next round
trip. A secret pasted with a trailing record (e.g. an `OPENVIKING_API_KEY`
copied with an extra line) therefore injects an arbitrary additional
variable into the persisted credentials file and silently corrupts it.
The fix neutralizes the line terminators at the single chokepoint where
values reach the file. A small `_env_line_safe` helper strips `\r`, `\n`,
and the NUL byte from each value, and both write sites in `_write_env_vars`
(the existing-key update branch and the appended-key branch) route through
it, so a value can only ever occupy the single line it is written on.
## What does this PR do?
Hardens the OpenViking memory provider's `.env` writer so a malformed or
pasted secret value can no longer break out of its `KEY=VALUE` line and
inject a rogue variable into the profile-scoped credentials file.
## Related Issue
N/A
## Type of Change
- [x] 🐛 Bug fix (non-breaking change that fixes an issue)
## Changes Made
- `plugins/memory/openviking/__init__.py`: add `_env_line_safe()` which
removes `\r`, `\n`, and `\x00` from a value, and apply it to both the
updated-key and appended-key write branches in `_write_env_vars()`.
- `tests/plugins/memory/test_openviking_provider.py`: add two regression
tests covering a fresh write and an in-place key update with embedded
CR/LF, asserting no injected line survives the read-back.
## How to Test
1. Run the targeted tests:
`pytest tests/plugins/memory/test_openviking_provider.py -k env_writer -q`
2. Reverting the `_env_line_safe` sanitization makes
`test_openviking_env_writer_strips_embedded_newlines_in_values` and
`test_openviking_env_writer_strips_newlines_when_updating_existing_key`
fail with a rogue `INJECTED_KEY=`/`ROGUE=1` line appearing in the file,
confirming the tests pin the bug.
3. `ruff check plugins/memory/openviking/__init__.py` and
`python scripts/check-windows-footguns.py plugins/memory/openviking/__init__.py`
both pass.

profile_name was only written on the agent's initial lazy create
(e8b7ce8c1); every parented child row — compression rotation, TUI
/branch, desktop branch first-persist — was created without it. A
non-default profile's lineage therefore turned NULL on its first
compression or branch and aggregated as "default" in unified session
lists, completing the cross-profile session-jump.
Fix the class at the DB layer: _insert_session_row's parent backfill now
COALESCEs profile_name from the parent alongside cwd/git_* (#64709
pattern), so any parented child inherits its lineage's owning profile.
Stamp it explicitly at the three create sites as well — compression
rotation (mirroring _ensure_db_session), TUI session.branch, and the
TUI first-prompt row persist — so rows are self-describing even when the
parent row predates the profile_name column.
Closes#62503
Root cause: session.resume already opened the requested profile's state.db,
but session.list / most_recent / delete / history / title / status, create's
immediate info payload, teardown, session.branch, and post-turn pending_title
still used the launch profile (_get_db / _current_profile_name).
Fix: add _db_for_profile / _profile_db / _session_db helpers and route
session.* methods through them; report requested profile on create/status;
lifecycle uses session-owned profile stores with branch profile_home inherit.
Rebase onto current main keeps _session_usage_snapshot in session info.
Flips the default fan-out cadence from per_iteration (advisors re-run on
every tool iteration, multiplying advisor spend by tool-loop depth) to
user_turn (advisors run once on the first message of each user turn; the
acting aggregator works the rest of the tool loop with that turn's
advice). Until per-mode benchmarks justify a costlier default, MoA
defaults to the cheapest, lowest-impact cadence (#67199).
One default for everyone — no split legacy/new-preset semantics; presets
that want per-step advising set fanout: per_iteration explicitly. All
three modes (user_turn / per_iteration / every_n:N) remain selectable;
every_n:1 still collapses to per_iteration (semantic identity), while
unparseable values now fall to user_turn (the default).
Docs updated with a default-change note; the per-iteration rerun test
pins its mode explicitly.

When a skill is created or edited with a description longer than
SKILL_PROMPT_DESC_LIMIT (60 chars), the tool response now includes a
system_prompt_preview field showing exactly what the system prompt
skill index will display. This gives the agent immediate feedback to
self-correct truncated trigger phrases.
Also adds tool schema guidance about the 57-char window and fixes a
stale docstring in skill_commands.py that incorrectly claimed the
system prompt renders the full description.
Follow-up on the salvaged commit: the xurl skill loads even when x_search
isn't registered (check_fn-gated on xAI credentials), so per the
cross-toolset reference rule the skill must not name it. Replaced the
skill's x_search routing block and workflow step with skill-native
wording (raw engageable posts, authenticated context, write-evidence
rule). The cross-surface comparison stays on surfaces where both are
known to exist: x-search feature docs, toolset description, tools-config
setup note, and the x_search tool schema (kept generic, no tool names).
Rewrote the routing tests to pin the placement contract, including that
the skill never names credential-gated surfaces.
Make the x_search / xurl boundary explicit in the skill, feature docs,
toolset metadata, setup note, and reference pages, while keeping the
model-facing x_search schema generic (no static xurl name).
Regression tests assert behavioral routing invariants rather than frozen
prose snapshots. Drop the stale CI-only plugin/hangup hunks already on
main so this rebases cleanly.
A direct run (cronjob action='run' / webhook-triggered manual fire) takes
the job's fire_claim and advances next_run_at. When it races the external
provider's scheduled fire for the same occurrence, Chronos loses the claim
and — by design — does not re-arm (the winner owns the re-arm). But the
direct-run winner never notified the provider, so the NAS one-shot for the
consumed occurrence was left stale forever and the recurring job silently
stopped firing.
Observed in production: a managed 1-minute review job stalled for 20 hours
because a GitHub-webhook direct run claimed the job 2s before the Chronos
fire arrived; every subsequent occurrence was orphaned while /api/status
stayed green.
Fix: after a *claimed* direct execution completes (success or failure —
next_run_at advances at claim time either way), call
_notify_provider_jobs_changed_safe() so the active provider re-arms the
post-run next_run_at. No-op for the built-in ticker; claim-lost direct
runs still never notify (the winning scheduler owns the re-arm).
skills/dogfood/SKILL.md sat at the root of the bundled skills tree,
making it one of the few uncategorized skills (Discord /skill
autocomplete listed it under 'uncategorized'; hermes_cli/commands.py
cited it as the example). Move it to
skills/software-development/dogfood/ alongside the other QA/testing
skills (test-driven-development, systematic-debugging,
requesting-code-review).
- git mv skills/dogfood -> skills/software-development/dogfood
(history preserved)
- fix test fixture path in tests/tools/test_browser_console.py
- update root-level-skill docstring examples (commands.py,
generate-skill-docs.py) to cite computer-use, which is still root-level
- drop 'dogfood' from the category list in hermes-agent-skill-authoring
SKILL.md (en + zh-Hans docs mirrors)
- docs: regenerate/move the bundled page to
software-development-dogfood (en + zh-Hans), update sidebars.ts,
skills-catalog.md, and the adversarial-ux-test related-skills link
E2E validated: fresh sync_skills() copies to the new nested path;
existing installs with the old flat copy keep it untouched (manifest is
name-keyed, hash unchanged -> skipped, no duplicate);
_get_category_from_path resolves 'software-development'; docusaurus
build green.
Verification follow-up for the #51226 salvage: the host call site guarded
select_context with hasattr(), but the ABC defines a default on every
engine, so the built-in ContextCompressor (and any non-implementing
engine) still paid per-request shallow copies of the conversation
history plus a hook call on every provider request. Identity-check the
bound method against ContextEngine.select_context and return the
request untouched — mirroring the existing base-method short-circuit in
_notify_context_engine_turn_complete — so the default path does zero
work, not just produces an identical result.
Adds two pins: the base no-op is never invoked (patched-to-raise base
stays silent), and ContextCompressor.__dict__ contains neither new verb.
Also registers the contributor email mapping for @chaos-xxl.
- website guide: on_turn_complete() now carries the same best-effort coverage
caveat as the ABC docstring (fires from the finalization seam; abnormal
early-return paths bypass it) — removes the doc/code inconsistency.
- test: finalization seam emits on_turn_complete with usage=None + the
interrupted flag for an interrupted finalized turn. Docstring records that
the negative early-return-bypass half is best-effort and deferred to a
shared-seam follow-up rather than pinned via a full run_conversation harness.
