Every PLUGIN-COMPAT __getattr__ now calls hermes_cli.plugin_compat.warn_once(facade, name, target) before
resolving, emitting a HermesPluginCompatWarning (FutureWarning) once per process per name: old path, new
path, removal target. Importing a facade for its live API stays silent; only resolving a moved name warns.
COMPAT_MANIFEST.md documents the warning and how to silence it during migration.
Verified the runtime never routes through a pointer: every entry point (run_agent, cli, hermes_cli.main,
gateway.run, tui_gateway.server, web_server, model_tools + tool discovery, hermes_state, cron.scheduler,
browser_tool, mcp_tool, kanban, auth) imports clean and `hermes doctor` runs end to end with the warning
promoted to an error.
Also restores the check_compat_pointers CI step to .github/workflows/lint.yml, which a0be177aac dropped
when the compat layer was regenerated (the lint script itself was present; the workflow step was not).
hermes_cli/plugin_compat.py, tests/test_plugin_compat_warning.py and the two-line insert per facade are
part of the compat layer and go away with it.
The Sep 2026 decomposition (PR #102117) makes internal import paths a non-API: names now live in
the focused modules that define them. This commit is the ONLY thing keeping the old paths alive,
so external plugins have time to update. It is deliberately a single, unsquashed commit:
git revert <this sha>
removes every shim, stub and manifest at once on the announced date. Nothing in-tree may depend on
these pointers: scripts/check_compat_pointers.py (wired into lint.yml) fails CI if it does.
What it adds (see COMPAT_MANIFEST.md, compat_manifest.json):
- 332 facade modules get one delimited `PLUGIN-COMPAT` block appended at the end of the file
- 1,172 moved names resolved lazily via a module `__getattr__` (PEP 562) — never a top-level import,
so no import cycles; facades that already had `__getattr__` get a chained one
- 592 third-party/stdlib names the old modules used to expose, with their original import statements
- 266 public definitions that had been deleted as unused, restored byte-for-byte from the pre-decomposition
tree (+40 private helpers and 16 imports pulled in only because a restored definition needs them)
- 3 deleted modules recreated as re-export stubs (gateway/startup_watchdog, hermes_cli/observability/
relay_runtime, tools/environments/modal_utils)
- private names (`_x`) get no pointer: they were never API (3,792 skipped)
Verified: all 335 touched modules import under a fresh HERMES_HOME and every manifest name resolves;
the lint reports zero in-tree uses; ruff clean; targeted suites unchanged.
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
Repo scanners (check_subprocess_stdin, check-windows-footguns --all) flagged 21 sites where
the r3 single-line collapses lost stdin=DEVNULL, encoding='utf-8'/errors='replace', the
'# windows-footgun: ok' same-line marker, or the getattr(os, 'geteuid') gate. Each guard is
restored at the call site (real portability/hang fixes, not suppressions).
Two silent-auth-failure paths from #36098 (also #66125):
- the local-URL guard only escaped the 'local' placeholder when the
HOST BLOCK had apiKey. A top-level apiKey in honcho.json — explicit
user intent, and what 'hermes honcho setup' writes for single-host
configs — was dropped on the floor, so AUTH_USE_AUTH self-hosts
401'd on every request. Now any explicit key in honcho.json (host
block or top level) is honored; only env-sourced keys are still
treated as likely-cloud and skipped for local URLs.
- named-profile host blocks do not inherit the default host's apiKey
(credential isolation is by design), but the failure was silent:
the profile ran unauthenticated and every tool said 'no context'.
Affirm isolation and warn loudly at config-resolution time instead,
the outcome #66125 proposed if inheritance is rejected.
Salvage of #2757 by @teyrebaz33 — rebased onto current Honcho plugin layout.
Stray control characters (e.g. terminal escapes pasted into HONCHO_BASE_URL
or config baseUrl) are dropped with a warning so SDK construction cannot
crash startup on Invalid non-printable ASCII character errors.
_resolve_or_create_client() used a plain dict.get(config.host) that
fails for dot-form profile host keys (e.g. "hermes.profile_a") even
though the _host_block() helper defined nearby handles the legacy
dot-form → underscore-form fallback correctly. The result:
_host_has_key evaluates to False for every authenticating user,
so effective_api_key is set to "local" and every Honcho API call
returns 401 Invalid JWT — cascade failure into silent data loss
for cross-peer queries and message sync.
Fixes by calling the existing _host_block() helper instead of
reimplementing the direct lookup. Local variable renamed from
_host_block → _host_block_local to avoid shadowing the function.
Closes#37436
HonchoClientConfig.from_global_config() only consulted top-level
baseUrl / base_url / HONCHO_BASE_URL in ~/.honcho/config.json. The
Honcho SDK's native config format — and what Claude Desktop writes —
nests the URL at endpoint.baseUrl. Users with that config format had
their self-hosted Honcho container silently ignored: every honcho_*
call routed to https://api.honcho.dev with a workspace_id that does not
exist there, so tools returned empty data with no error anywhere.
Resolution order in from_global_config(), highest first:
1. endpoint.baseUrl (SDK-native, what Claude Desktop writes)
2. baseUrl / base_url (root-level, existing behavior)
3. HONCHO_BASE_URL (existing env var)
4. HONCHO_URL (the SDK's own env var, honcho/client.py:234)
HONCHO_URL is also read in from_env(). from_global_config() delegates to
from_env() whenever the config file is missing or unreadable, so an env
fallback wired into only one of the two would silently do nothing for
users with no config file.
A non-dict endpoint value falls through cleanly rather than raising.
Existing users are unaffected — the new sources are consulted only when
the existing ones resolve to None.
The INFO log for the base_url-unset case now says so explicitly instead
of printing only the host. The SDK resolves that case from its own
ENVIRONMENTS map (honcho/client.py:36-39), which for environment=
production means the public cloud; a self-hosted user whose config was
not picked up otherwise sees a healthy-looking startup line.
Closes#43800.
- _submit_background and _prefetch_provider: replace unreadable
(lambda inner: (lambda: ctx.run(inner)))(fn) with functools.partial(ctx.run, fn)
- from_env(): set config_path=resolve_config_path() so bound_config_path()
doesn't re-resolve from ContextVar on daemon threads (the exact bug
the PR fixes for from_global_config)
Review follow-ups for salvaged PR #83525.
The dict was written on every build and popped/cleared on eviction and
reset, but no read site remained — timeout staleness detection moved
into the cache key itself (a timeout change produces a new identity and
_slot_for evicts the old slot), which the isolation tests already pin.
Flagged in review by @spfcraze.
Profile isolation is a ContextVar; plain threading.Thread targets start
with an empty context, so the plugin's nine daemon threads (session
init, prewarm, first-turn base/prefetch, prefetch, sync, memwrite,
async writer, context prefetch) resolved ambient state — config path,
active host, hermes home, oauth token paths — against the DEFAULT
profile whenever they ran under a routed profile's turn.
Adds spawn_context_thread(), which copies the caller's context at spawn
time so the thread sees the profile scope it was created under, and
routes every plugin thread spawn through it. Defense-in-depth under the
bound-config work: even ambient resolution on these threads now lands
on the right profile.
The copy_context approach follows the gateway's own
_run_in_executor_with_context pattern; #81401 applied it to the init
thread, this extends it to all nine spawns.

Replaces the process-wide first-config-wins client singleton with a
per-identity slot map. The singleton baked the first profile's
workspace_id and bearer into one shared client, so in multi-profile
processes (gateway multiplexer, dashboard, cron) every profile's
memory landed in whichever workspace initialized first — cross-tenant
bleed with no error (#69123, #74065).
cache key: (host, workspace, base_url, environment, provenance paths,
effective timeout, credential fingerprint). the fingerprint hashes the
OAuth REFRESH token (stable across in-place access-token rotation,
changes on re-auth/account switch) or the static api key — so
re-running 'hermes honcho setup' to switch accounts produces a new
identity instead of silently reusing the old account's client and
writing tenant B's data with tenant A's bearer, a hole per-path keys
alone cannot close.
same-identity slots with a different fingerprint or timeout are
EVICTED on replacement, so credential churn can't accumulate pinned
clients — the replaced client's pools close when its last holder
drops. timeout changes rebuild via the key (the old explicit staleness
check is subsumed). failed in-place OAuth rotation resets only the
client's own slot. reset_honcho_client() clears everything, preserving
test and oauth-flow re-login semantics.
per-config-identity caching was first proposed in #69142; the
provenance-key shape follows #81401. this implementation adds the
credential fingerprint and eviction they lacked.

Profile isolation in every multi-profile process (gateway multiplexer,
dashboard, cron) is a ContextVar (set_hermes_home_override) that
threading.Thread targets cannot see. The plugin's daemon threads —
async writer, prefetch, sync, first-turn, init — all funnel through
HonchoSessionManager.honcho, which called get_honcho_client() with NO
config, re-resolving resolve_config_path()/resolve_active_host() from
the ContextVar-blind thread context: every background memory access
landed on the DEFAULT profile. Worse, the OAuth paths did the same, so
a token refresh on a daemon thread could persist the rotated token
into the wrong profile's honcho.json, and a 401 recovery could burn
the wrong profile's single-use refresh token.
- HonchoClientConfig gains provenance (config_path, hermes_home)
captured at resolution time inside the caller's profile scope, with
bound_config_path() for consumers
- manager.honcho passes the bound config instead of re-resolving
- OAuth paths (_apply_fresh_oauth_token, _refresh_cached_oauth,
_reauth_required, _force_reauth) use the bound path
- the honcho.json timeout memo becomes path-keyed instead of
single-slot, so multi-profile processes stop thrashing it and
returning profile A's timeout for profile B
Groundwork for per-identity client caching (#69123, #74065); the
provenance-field shape follows #81401.

An expired access token could pause Honcho memory for hours with no
user-facing signal: ensure_fresh_token swallowed every exchange failure
and returned the stale token, no code handled a 401 from the Honcho API,
and each failed dialectic cycle widened the cadence backoff. Hypothesis
for the trigger (not confirmed): the refresh POST times out after the
server already rotated the token pair, Hermes keeps the old refresh
token, and the eventual replay lands outside the server's 60-second
rotation grace window, which revokes the whole grant.
- oauth: the exchange reads the token endpoint's error body instead of
discarding it. invalid_grant and other permanent OAuth errors mark the
grant dead so no code retries a revoked grant; transient failures retry
once immediately, which keeps a replayed refresh token inside the grace
window. Log lines redact token values.
- oauth: force_refresh_token() rotates the token now, ignoring local
expiry, to recover from a server-side 401.
- session: dialectic_query and _flush_session treat a 401 as a trigger to
force one token rotation and retry the call exactly once. A persistent
auth failure raises HonchoAuthError (dialectic) or records the failure
(sync) instead of being returned as an empty result.
- provider: injects a one-time notice into the memory context so the
model tells the user memory is paused and 'hermes honcho setup'
restores it. Auth failures no longer widen the dialectic cadence
backoff.
New tests cover the exchange retry, invalid_grant terminality plus
re-login recovery, forced refresh, 401 retry on both the sync and
dialectic paths, the one-time notice, and the backoff exemption.
Route HINDSIGHT_API_KEY/HINDSIGHT_LLM_API_KEY, HONCHO_API_KEY, SUPERMEMORY_API_KEY, MEM0_API_KEY and RETAINDB_API_KEY reads through agent.secret_scope.get_secret so multiplexed turns resolve the active profile's key instead of the process environment. Also guard supermemory post_setup's os.environ write on not is_multiplex_active() — writing one profile's key into the process-global env pollutes sibling profiles; the single-profile convenience path is unchanged.
On Windows with Chinese locale (GBK), subprocess.run(text=True) without
explicit encoding causes UnicodeDecodeError crashes. This fix adds
encoding='utf-8', errors='replace' to all subprocess.run() and
subprocess.Popen() calls that use text=True across 76 non-test Python files.
Fixes#53428 (master tracker for Windows GBK locale crash).
Note: credential_pool.py and electron changes excluded per reviewer request —
those will be submitted as separate focused PRs.
The staleness check's bespoke mtime memo keyed only on the user
config.yaml, but load_config() merges the managed-scope config
(HERMES_MANAGED_DIR/config.yaml, /etc/hermes) whose leaf keys win. A
managed honcho.timeout with no user config.yaml made the memo cache
'no timeout' while _build resolved the managed value — the same
perpetual-rebuild mismatch this PR fixes for honcho.json. A managed
timeout edit was likewise invisible while the user file's mtime stayed
put.
load_config_readonly() is already cached on both files' signatures plus
the env-ref snapshot, so use it instead of duplicating that
invalidation logic; the defensive deepcopy the old memo existed to
avoid is skipped by the readonly variant. Drive the rebuild test
through a real config.yaml and add a HERMES_MANAGED_DIR regression
test covering stable reuse and managed-timeout edits.
The staleness check added in #66052 resolved the timeout from env,
config.yaml, and the default only, while the build path also reads the
honcho.json host block (timeout/requestTimeout). With a timeout
configured in honcho.json, the two permanently disagreed: every
no-config get_honcho_client() call — i.e. every HonchoSessionManager
.honcho property access — interpreted the mismatch as a config change
and tore down and rebuilt the client, defeating the singleton on the
hot path it was meant to protect.
Teach the check to read honcho.json through the same host-aware chain
as from_global_config, memoized on the file's mtime_ns so the per-call
cost stays one stat(). A genuine honcho.json timeout change is now also
detected, extending #57437 to that config surface.
Follow-ups for the consolidated salvage:
- Memoize the config.yaml-derived timeout on the file's mtime_ns so the
rebuild-on-timeout-change check from PR #57437 costs one stat() per
get_honcho_client() call instead of a full YAML load on the hot path.
- hermes honcho status now displays the host-block-resolved
dialecticCadence (remnant from PR #63776, whose runtime fix landed
in #62290).
- AUTHOR_MAP entries for the salvaged contributor emails.
The Honcho client singleton cached the HTTP timeout at first build.
In long-lived processes (gateway, dashboard), changing the timeout
via config.yaml or HONCHO_TIMEOUT had no effect until restart.
Track the resolved timeout alongside the cached client and compare
on each get_honcho_client() call. When the timeout differs, reset
the singleton so the next call rebuilds with the new value.
Fixes#57347
Fixes Honcho client initialization for setup-generated configs that store
connection details in a named host block (e.g. "local"). Previously:
- base_url was only read from flat config root, not from host_block.
- resolve_active_host() ignored defaultHost and always used the Hermes
profile key ("hermes"), so the host block lookup returned {} and the
api_key was also lost.
FixesNousResearch/hermes-agent#61661
queryRewrite (default off) gates the latest-message rewrite so the
extra auxiliary LLM call is opt-in. firstTurnBaseWait and
firstTurnDialecticWait expose the turn-1 bounded waits in seconds
(0 disables). All three resolve host-block-first like every other
field. Also pins per-host timeout resolution with tests.
dialecticMaxChars (default 600) is documented as the budget for the dialectic
supplement auto-injected into the system prompt every turn — a small recurring
cost that is correct to bound tightly. But dialectic_query() applied that cap
unconditionally, so explicit honcho_reasoning tool calls — where the model
deliberately spends a turn asking for a synthesized answer — were silently
truncated mid-word to 600 chars with a trailing " …", no error surfaced. The
full answer is returned by Honcho server-side; the clip happens client-side.
The auto-injection path already has its own token-based budget (contextTokens,
enforced in prefetch() via _truncate_to_budget), so the char cap's real job is a
cheap always-on guardrail for that recurring injection. Explicit tool results
are already bounded server-side by Honcho's dialectic MAX_OUTPUT_TOKENS and don't
need the injection cap — sibling tools (honcho_search, honcho_context) don't
post-clip their results either.
Add apply_injection_cap (default True, preserving current behavior) to
dialectic_query(); the honcho_reasoning tool handler passes False so it returns
Honcho's full synthesized answer. Auto-injection is unchanged. Tests cover both
the capped injection path and the uncapped tool path.

injectionFrequency, contextCadence, and dialecticCadence were read
only via raw.get() which checks root-level keys in honcho.json.
Settings placed inside hosts.<name> (the normal per-host location)
were silently ignored, falling back to defaults.
- Add typed dataclass fields: injection_frequency, context_cadence,
dialectic_cadence with host-block-first resolution chains matching
the pattern used by all other config fields.
- Update HonchoMemoryProvider.initialize() to read from typed cfg
fields instead of cfg.raw directly.
- Fix search_context tests that mocked _honcho directly — the
.honcho property getter calls get_honcho_client() which overwrites
the backing field, so use patch.object on the property instead.
- Add injection_frequency and context_cadence config override tests.
HonchoClientConfig timeout/requestTimeout resolution skipped the per-host config
block, silently dropping a host-scoped timeout and falling through to the global
config.yaml value (or the default). Add the host block at the front of the
resolution chain, consistent with every other field (base_url, api_key, etc.).
Follow-up to #53791 addressing review feedback: the footgun checker treated
capture_output=/stdout=/stderr=/check_output as proof a subprocess can't pop a
Windows console. That invariant is false — stream redirection controls where a
child's output goes, not whether a console is allocated. From a console-less
parent (Desktop/Electron, pythonw.exe, detached gateway/cron) a console-subsystem
child still flashes a window even when fully captured.
- check-windows-footguns.py: capture/redirect/check_output is no longer a blanket
safe-pass. Added _WINDOWS_FLASHING_PROGRAMS (git/gh/npm/node/python/uv/ffmpeg/
docker/powershell/…); calls to those are flagged even when captured. Non-flashing
programs keep the capture exemption (no 271-site noise). _subprocess_compat.run/
popen calls are inherently safe (wrapper injects CREATE_NO_WINDOW).
- Routed the 35 genuine flashing git/gh/npm/uv/ffmpeg/docker spawns through the
_subprocess_compat.run/popen chokepoint (Brooklyn's wrapper from #53810) — the
durable fix, not per-site annotations. cmd.exe /c start stays # ok (intentional).
- Updated tests + CONTRIBUTING.md rule #17 to the corrected invariant.

README never mentioned reasoningHeuristic and listed reasoningLevelCap as an orphaned cap with the wrong default (— vs "high"). Add the query-adaptive scaling note + the reasoningHeuristic/reasoningLevelCap rows (grouped under Dialectic & Reasoning), matching the wording already on the hosted honcho.md page, and add a pointer from the memory-providers overview.
* fix(honcho): default the CLI peer prompt to the OAuth consent name
The CLI runs the grant with apply_config=False, so the peerName the user just entered at consent was dropped and the wizard's 'Your name' prompt fell back to $USER. Surface it as a transient OAuthCredential.consent_peer_name (set even when config isn't merged) and seed the prompt default from it.
* feat(honcho): split OAuth client_id by surface (cli=hermes-agent, desktop=hermes-desktop)
resolve_endpoints now picks the client_id from the initiating surface and
threads it through authorize -> token exchange -> persisted grant -> refresh,
so the CLI and desktop register as distinct OAuth clients. Surface-specific
env overrides (HONCHO_OAUTH_CLIENT_ID_CLI/_DESKTOP) win over the generic
HONCHO_OAUTH_CLIENT_ID, which still overrides every surface.
* feat(honcho): show OAuth vs API key in status; detect existing OAuth in setup
status now prints 'Auth: OAuth (clientId, token valid Xm/expired)' instead of
masking the OAuth access token as a generic API key; setup notes an existing
OAuth grant when re-run.
* docs(honcho): drop 'shared pool' wording from unified observation mode help
* fix(honcho): cross-process lock around OAuth refresh to prevent grant revocation
The in-process threading lock can't stop a sibling process (another profile or
the desktop app sharing honcho.json) from replaying the single-use refresh
token and tripping reuse-detection, which revokes the whole grant. Guard the
read-refresh-persist section with an OS file lock on <config>.lock so only one
process rotates at a time; the others re-read the freshly-persisted token.
Best-effort: platforms without flock degrade to in-process serialization.
* refactor(honcho): one OAuth client (hermes-agent) for all surfaces
Collapse the per-surface client_id split. CLI and desktop now use a single
client_id (hermes-agent); consent branding/UI still adapt via the source query
param. One grant identity means no clientId-vs-refresh-token desync that could
get the grant revoked. HONCHO_OAUTH_CLIENT_ID still overrides for self-hosting.
* fix(honcho): per-session resolves to session_id, never remapped by title
Reorder resolve_session_name so stable identifiers win over labels: gateway
per-chat key first, then the per-session session_id, then the cwd map / title.
A (possibly auto-generated) title can no longer remap a live per-session
conversation onto a second Honcho session mid-stream — fixes the desktop, which
is per-conversation via session_id. Consequence: a gateway's per-chat key now
also wins over a title (titles never remap a stable id).
When Hermes runs in TUI mode, the gateway child process communicates with
the Node.js parent over a JSON-RPC protocol on stdin. Subprocess calls that
inherit this stdin fd can trigger a race condition where the child's stdin
read returns EOF, causing the gateway to exit cleanly (exit code 0) mid-tool-
execution.
This is the same root cause as issue #14036 (byterover plugin) and PR #39257
(SSH environment backend). This commit applies the fix — stdin=subprocess.DEVNULL
— to all 85 subprocess.run() and subprocess.Popen() calls that execute inside
the TUI gateway child process.
Scope: TUI-context code only (agent/, tools/, plugins/, tui_gateway/server.py).
CLI code (cli.py, hermes_cli/), tests, scripts, and gateway process management
are excluded — they don't run inside the TUI child and inherit the terminal's
stdin, not the JSON-RPC pipe.
85 call sites across 28 files. All files pass syntax check.
* fix(plugins): add thread-safe lazy-singleton helpers, fix honcho TOCTOU (#24759)
get_honcho_client() and fal's _load_fal_client() used unlocked
check-then-init: racing threads both ran the expensive build and the
loser's client (open connection) leaked.
Rather than one-off locks, add plugins/plugin_utils.py with two
reusable primitives every plugin author can drop in:
- lazy_singleton: decorator for zero-arg accessors
- SingletonSlot: manual slot for config-keyed accessors (first wins)
Both use double-checked locking; factory runs at most once; failed
builds aren't cached. honcho is the reference consumer; fal's sibling
TOCTOU gets a matching double-checked lock. Plugin dev guide documents
the pattern so future plugins don't reintroduce the race.
Closes#24759
* test(honcho): update reset test for SingletonSlot internals
test_reset_clears_singleton poked the removed _honcho_client module
global directly. Assert through the slot's public peek() surface
instead, matching the #24759 refactor.
Self-hosted Honcho setup had four sharp edges:
- local/cloud URLs ending in /vN double-prefixed by the SDK (/v3/v3/... 404)
- authenticated local servers had no setup prompt for a JWT/bearer token
- profile-derived host keys could be dot-containing workspace IDs Honcho rejects
- memory-provider config files with API keys written world-readable per umask
This keeps existing behavior but makes those paths safer:
- strip a trailing /vN version segment from any configured baseUrl before SDK
init (the SDK's route builders always prepend their own version prefix);
auth-skipping stays loopback-only
- add an optional local JWT/bearer prompt in honcho setup, stored under
hosts.<host>.apiKey
- derive new profile host keys with underscores, still reading legacy
hermes.<profile> blocks
- write memory-provider config files atomically with 0600 via a shared
utils.atomic_json_write(mode=) arg (honcho/hindsight/mem0/supermemory)
- skip honcho.json parsing in gateway cache-busting unless Honcho is the active
memory provider; memoize by honcho.json mtime when active
- bust the gateway agent cache on memory.provider change
- add a hermes memory setup <provider> one-liner so fresh installs can configure
a named provider without the picker (the per-provider hermes <provider>
subcommand only registers once that provider is active)

The original key 'pinPeerName' from #14984 is ambiguous: a fresh
reader can't tell whether it pins the user peer or the AI peer from
the name alone. The resolver only ever pins the user-side
(_resolve_user_peer_id short-circuits when pin_peer_name is true; the
AI peer is already pinned by construction via aiPeer).
Add 'pinUserPeer' as the canonical alias. Both keys land on the
same internal pin_peer_name field; precedence is host pinUserPeer →
host pinPeerName → root pinUserPeer → root pinPeerName → default.
Host-level always beats root-level regardless of alias, so a host
block can still explicitly disable a root-level pin even via the new
key.
Make _resolve_bool variadic so it can express the four-value
precedence chain. All existing callers pass two positional args +
default keyword, which the new signature accepts unchanged.
Internal var name (pin_peer_name) stays the same to keep the
cherry-picked #27371 commits clean and avoid a noisy rename diff.
Six days after #23937 (608 fixes) the codebase had accumulated 241 new
PLR6201 violations. Same mechanical `x in (...)` → `x in {...}` fix,
same zero-risk profile: set lookup is O(1) vs O(n) for tuple and the
two are semantically equivalent for hashable scalar membership tests.
All 241 instances fixed via `ruff check --select PLR6201 --fix
--unsafe-fixes`, zero remaining. Every changed value is a hashable
scalar (str/int/None/enum/signal); no risk of unhashable runtime
errors. No behavior change.
Test plan:

* feat(security): supply-chain advisory checker + lazy-install framework + tiered install fallback
Three coordinated mitigations for the Mini Shai-Hulud worm hitting
mistralai 2.4.6 on PyPI (2026-05-12) and for the next single-package
compromise that follows.
# What this PR makes true
1. Users with the poisoned mistralai 2.4.6 in their venv get a loud
detection banner with copy-pasteable remediation steps the moment
they run hermes (and on every gateway startup).
2. One quarantined / yanked PyPI package can no longer silently demote
a fresh install to 'core only' — the installer keeps every other
extra and tells the user which tier landed.
3. Future opt-in backends (Mistral, ElevenLabs, Honcho, etc.) can
lazy-install on first use under a strict allowlist, instead of
eagerly pulling everything at install time.
# Detection: hermes_cli/security_advisories.py
- ADVISORIES catalog (one entry currently: shai-hulud-2026-05 for
mistralai==2.4.6). Adding the next one is a single dataclass.
- detect_compromised() uses importlib.metadata.version() — no pip
dependency, works in uv venvs that lack pip.
- Banner cache (~/.hermes/cache/advisory_banner_seen) rate-limits
the startup banner to once per 24h per advisory.
- Acks persisted to security.acked_advisories in config.yaml; never
re-banner after ack.
- Wired into:
* hermes doctor — runs first, prints full remediation block
* hermes doctor --ack <id> — dismisses an advisory
* cli.py interactive run() and single-query branches — short
stderr banner pointing at hermes doctor
* gateway/run.py startup — operator-visible warning in gateway.log
# Lazy-install framework: tools/lazy_deps.py
- LAZY_DEPS allowlist maps namespaced feature keys (tts.elevenlabs,
memory.honcho, provider.bedrock, etc.) to pip specs.
- ensure(feature) installs missing deps in the active venv via the
uv → pip → ensurepip ladder (matches tools_config._pip_install).
- Strict spec safety regex rejects URLs, file paths, shell metas,
pip flag injection, control chars — only PyPI-by-name accepted.
- Gated on security.allow_lazy_installs (default true) plus the
HERMES_DISABLE_LAZY_INSTALLS env var for restricted/audited envs.
- Migrated three backends as proof of pattern:
* tools/tts_tool.py — _import_elevenlabs() calls ensure first
* plugins/memory/honcho/client.py — get_honcho_client lazy-installs
* tts.mistral / stt.mistral entries pre-registered for when PyPI
restores mistralai
# Installer fallback tiers
scripts/install.sh, scripts/install.ps1, setup-hermes.sh:
- Centralised _BROKEN_EXTRAS list (currently: mistral). Edit one
array when a transitive breaks; users keep every other extra.
- New 'all minus known-broken' tier between [all] and the existing
PyPI-only-extras tier. Only kicks in when [all] fails resolve.
- All three tiers explicit: every fallback announces which tier
landed and prints a re-run hint when not on Tier 1.
- install.ps1 and install.sh both regenerate their tier specs from
the same _BROKEN_EXTRAS array so updates stay in sync.
Side effect: install.ps1 Tier 2 spec previously hardcoded 'mistral'
in its extra list — bug fixed by the refactor (mistral is filtered
out).
# Config
hermes_cli/config.py — DEFAULT_CONFIG.security gains:
- acked_advisories: [] (advisory IDs the user has dismissed)
- allow_lazy_installs: True (security gate for ensure())
No config version bump needed — both keys nest under existing
security: block, and load_config's deep-merge picks up DEFAULT_CONFIG
defaults for users with older configs.
# Tests
tests/hermes_cli/test_security_advisories.py — 23 tests covering:
- detect_compromised matches/non-matches, wildcard frozenset
- ack persistence, idempotence, blank rejection, config-failure path
- banner cache rate limiting + 24h re-banner + ack-stops-banner
- short_banner_lines / full_remediation_text / render_doctor_section /
gateway_log_message
- shipped catalog well-formedness invariant
tests/tools/test_lazy_deps.py — 40 tests covering:
- spec safety: 11 safe parametrized + 18 unsafe parametrized
- allowlist: unknown-feature rejection, namespace.name shape,
every shipped spec passes the safety regex
- security gating: config flag, env var, default, fail-open
- ensure() happy/sad paths: already-satisfied, install success,
pip stderr surfaced on failure, install-succeeds-but-still-missing
- is_available, feature_install_command
Combined: 63 new tests, all passing under scripts/run_tests.sh.

* build(deps): pin every direct dep to ==X.Y.Z (no ranges)
Companion to the supply-chain advisory work: replace every >=/</~= range
in pyproject.toml's [project.dependencies] and [project.optional-dependencies]
with an exact ==X.Y.Z pin sourced from uv.lock.
Why: ranges allow PyPI to ship a fresh version of any direct dep at any
time without a code review on our side. With ranges, the malicious
mistralai 2.4.6 release would have been pulled by every fresh
'pip install -e .[all]' for the hours between upload and PyPI's
quarantine — exactly the install window we got hit on. Exact pins close
that window: the only way a new package version reaches a user is via
an intentional update on our end.
What the user-facing change is: nothing, behavior-wise. Every package
resolves to the same version it was already resolving to via uv.lock —
the pins just remove the resolver's freedom to pick a different one.
Cost: any user installing Hermes alongside another package that requires
a newer pin gets a resolver conflict. Acceptable for our isolated-venv
install path; documented in the new comment block.
Build-system requires line (setuptools>=61.0) is intentionally left
as a range — pinning the build backend would block fresh pip from
bootstrapping the build on architectures where that exact wheel isn't
available.
mistral extra (mistralai==2.3.0) is pinned but stays out of [all]
(per PR #24205). 'uv lock' regeneration will fail until PyPI restores
mistralai; lockfile regeneration is gated behind that, NOT on every PR.
LAZY_DEPS in tools/lazy_deps.py also moved to exact pins so the lazy-
install pathway can never resolve a different version than the one
declared in pyproject.toml.
Validation:
- Cross-checked all 77 pinned direct deps in pyproject.toml against
uv.lock — every pin matches the resolved version exactly.
- Cross-checked all LAZY_DEPS specs against uv.lock — same.
- 'uv pip install -e .[all] --dry-run' resolves 205 packages cleanly.
- tests/tools/test_lazy_deps.py + tests/hermes_cli/test_security_advisories.py
→ 63/63 passing (every shipped spec passes the safety regex).
- Doctor + TTS + transcription targeted suite → 146/146 passing.
* build(deps): hash-verify transitives via uv.lock; remove unresolvable [mistral] extra
You asked: 'what about the dependencies the dependencies rely on?' —
correctly noting that exact-pinning direct deps in pyproject.toml does
NOT cover the transitive graph. `pip install` and `uv pip install` both
re-resolve transitives fresh from PyPI at install time, so a compromised
transitive (e.g. `httpcore` if it got worm-poisoned tomorrow) would
still hit our users even with every direct dep exact-pinned.
# What this commit fixes
1. **Both real installer scripts now prefer `uv sync --locked` as Tier 0.**
uv.lock records SHA256 hashes for every transitive — a compromised
package with a different hash gets REJECTED. Falls through to the
existing `uv pip install` cascade if the lockfile is missing or
stale, with a loud warning that the fallback path does NOT
hash-verify transitives. Previously only `setup-hermes.sh` (the dev
path) used the lockfile; `scripts/install.sh` and `scripts/install.ps1`
(the paths fresh users actually run) skipped it.
2. **Removed the `[mistral]` extra entirely.** The `mistralai` PyPI
project is fully quarantined right now — every version returns 404,
so any pin we wrote was unresolvable, which broke `uv lock --check`
in CI. Restoration is documented in pyproject.toml as a 5-step
checklist (verify, re-add extra, re-enable in 4 modules, regenerate
lock, optionally re-add to [all]).
3. **Regenerated uv.lock.** 262 packages, mistralai/eval-type-backport/
jsonpath-python pruned. `uv lock --check` now passes.
# Defense-in-depth view
| Layer | Where | Protects against |
|----------------------------|-------------------|-------------------------------------------|
| Exact pins in pyproject | direct deps | new mistralai 2.4.6-style direct compromise |
| uv.lock + `--locked` install | transitive graph | transitive worm injection |
| Tier-0 hash-verified path | install.sh / .ps1 | actually USE the lockfile in fresh installs |
| `uv lock --check` CI gate | every PR | drift between pyproject and lockfile |
| `hermes_cli/security_advisories.py` | runtime | cleanup for users who already got hit |
The exact pinning + hash verification together close the supply-chain
gap. Without the lockfile path, exact pins alone are theater.
# Validation
- `uv lock --check` → passes (262 packages resolved, no drift).
- `bash -n` on install.sh + setup-hermes.sh → OK.
- 209/209 tests passing across new + adjacent test files
(test_lazy_deps.py, test_security_advisories.py, test_doctor.py,
test_tts_mistral.py, test_transcription_tools.py).
- TOML parse OK.
* chore: remove community announcement drafts (PR body covers it)
* build(deps): lazy-install every opt-in backend (anthropic, search, terminal, platforms, dashboard)
Extends the lazy-install framework to cover everything that's not used by
every hermes session. Base install drops from ~60 packages to 45.
Moved out of core dependencies = []:
- anthropic (only when provider=anthropic native, not via aggregators)
- exa-py, firecrawl-py, parallel-web (search backends; only when picked)
- fal-client (image gen; only when picked)
- edge-tts (default TTS but still optional)
New extras in pyproject.toml: [anthropic] [exa] [firecrawl] [parallel-web]
[fal] [edge-tts]. All added to [all].
New LAZY_DEPS entries: provider.anthropic, search.{exa,firecrawl,parallel},
tts.edge, image.fal, memory.hindsight, platform.{telegram,discord,matrix},
terminal.{modal,daytona,vercel}, tool.dashboard.
Each import site now calls ensure() before importing the SDK. Where the
module had a top-level try/except (telegram, discord, fastapi), the
graceful-fallback pattern was extended to lazy-install on first
check_*_requirements() call and re-bind module globals.
Updated test_windows_native_support.py tzdata check from snapshot
(>=2023.3 literal) to invariant (any version + win32 marker).
Validation:
- Base install: 45 packages (was ~60); 6 newly-extracted packages absent
- uv lock --check: passes (262 packages, no drift)
- 209/209 lazy_deps + advisory + doctor + tts/transcription tests passing
- py_compile clean on all 12 modified modules
Three int() calls in HonchoClient.from_global_config() parsed
dialecticMaxChars, messageMaxChars, and dialecticMaxInputChars
directly without guards. A malformed value in honcho.json would
raise ValueError and abort provider initialization entirely.
Add _parse_int_config() helper following the existing
_parse_context_tokens() pattern, and replace all three raw
int() calls with it.
Two small follow-ups to the PR review:
- Hoist hashlib import from _enforce_session_id_limit() to module top.
stdlib imports are free after first cache, but keeping all imports at
module top matches the rest of the codebase.
- _resolve_api_key now URL-parses baseUrl and requires http/https +
non-empty netloc before returning the 'local' sentinel. A typo like
baseUrl: 'true' (or bare 'localhost') no longer silently passes the
credential guard; the CLI correctly reports 'not configured'.
Three new tests cover the new validation (garbage strings, non-http
schemes, valid https).
When no explicit timeout is configured (HonchoClientConfig.timeout,
honcho.timeout / requestTimeout, or HONCHO_TIMEOUT), get_honcho_client
previously constructed the SDK with no timeout kwarg, letting the
underlying httpx client hang indefinitely if the Honcho backend
became unreachable mid-request.
This is a silent-failure hazard on the post-response path of
run_conversation: the memory_manager.sync_all() / queue_prefetch_all()
calls fire after the agent has already generated its final reply, so
a stalled Honcho request blocks run_conversation from returning.
The gateway never logs "response ready" and never delivers the
response to the platform (Telegram, etc.), even though the text is
already saved to the session file.
Repro: unplug the network or block app.honcho.dev mid-turn after
the model has produced its final message. Without this change,
_run_agent never returns. With it, the call aborts after 30s,
run_conversation returns, and the gateway delivers the response
(Honcho sync failure is logged and swallowed as before).
The default applies only when nothing is configured, so any
deployment that has explicitly set timeout / HONCHO_TIMEOUT /
honcho.timeout / honcho.requestTimeout keeps its existing value.
Self-hosted deployments that genuinely need a longer ceiling can
still override via any of those knobs.
Gateway session keys (Matrix "!room:server" + thread event IDs, Telegram
supergroup reply chains, Slack thread IDs with long workspace prefixes) can
exceed Honcho's 100-character session ID limit after sanitization. Every
Honcho API call for those sessions then 400s with "session_id too long".
Add a helper that enforces the 100-char limit after sanitization:
short keys (the common case) short-circuit unchanged; over-limit keys
keep a prefix and append a deterministic `-<8 hex>` SHA-256 suffix over
the original key so two long keys sharing a leading segment can't
collide onto the same truncated ID.
Adds 7 regression tests in tests/honcho_plugin/test_client.py covering
short / exact-limit / long / deterministic / collision-resistant /
allowlist-preserving / hash-suffix-present cases.
