Simplify-code findings:
- _authenticated_json: replace manual header construction with
self._headers(include_tenant=False) — eliminates duplication with
_headers() and includes Content-Type consistently.
- _health_requires_credentials: replace getattr(exc, 'status_code')
with _status_code_from_error(exc) for consistency with the existing
error-classification utility. Drop the fragile string-matching
fallback — _parse_response always sets status_code on
_OpenVikingHTTPError, so 401/403 check is sufficient.
- Relax test header assertions to check presence/absence of specific
headers rather than exact dict equality, so they survive the
header-construction refactor.
Hosted OpenViking (Volcengine) rejects anonymous GET /health with
AuthenticationError, which made the provider look unhealthy and silently
disabled automatic memory mirroring. Keep the anonymous probe first for
identity safety, then retry once with the configured API key only when
the server demands credentials.
Fixes#78410
Gap-fill from the follow-up commit's own review:
- __init__.py: restore getattr tolerance in _pop_auth_notice — test
fixtures outside tests/honcho_plugin/ install minimal fake managers
without pop_auth_notice (tests/test_honcho_startup_fail_open.py's
SlowManager failed with AttributeError). Exceptions still propagate;
only the blanket except was dropped.
- test_auth_recovery.py: the fast-path test used a raising stub, but
_reauth_required swallows all exceptions — the test passed even with
the fast path removed. Rewritten as a recording spy with a call-count
assertion; mutation-verified (removing the fast path now fails it).
- test_auth_recovery.py: autouse fixture resetting oauth module dicts
(_dead_grants, _refresh_failure_at, _reauth_check_cache,
_expiry_cache) so state can't leak between tests.
honcho_plugin 293 + test_honcho_startup_fail_open 7 + plugins/memory
285 = 585 passed.
Follow-ups from review of #80590:
- oauth.py: extract _rotate_and_persist() — the twin ~18-line
OAuthRefreshError permanent/transient handling blocks in
ensure_fresh_token and force_refresh_token were byte-identical
except the log verb.
- oauth.py: cap the exchange cycle at _REFRESH_TOTAL_BUDGET_SECONDS
(20s). The retry runs while holding the global refresh locks on the
path to a memory call; a timed-out first attempt no longer earns a
second full 15s exchange (~32s lock hold -> <=20s).
- oauth.py: transient-failure cooldown (_refresh_failure_at, 30s).
Waiting threads and later turns fail open to the stale token instead
of serializing their own full exchange cycles against an endpoint
that just failed. Cleared on successful rotation and re-login.
- oauth.py: mtime-gate reauth_required()'s config read — the dead-grant
state persists until re-login, and the verdict can only change when
the config file is rewritten; drop the per-call read+parse.
- oauth.py: derive _TOKEN_VALUE_RE from ACCESS_TOKEN_PREFIX /
REFRESH_TOKEN_PREFIX so a prefix change can't silently break
redaction; promote redact_tokens to public (session.py imported the
private name).
- session.py: fast path in _reauth_required — skip config-path
resolution entirely while no grant is dead (runs before every SDK
call).
- session.py: client-generation counter closes the fetch/store race in
_sdk_session/_get_or_create_peer — an object resolved from the old
client mid-rebuild is no longer cached (it would 401 forever and burn
a token rotation per retry).
- __init__.py: drop the getattr/callable/except triple-guard in
_pop_auth_notice; the manager is always None or HonchoSessionManager.
7 new tests (budget, cooldown x3, generation guard, fast path); all
mutation-checked (disabling each guard fails its test). honcho_plugin
293 passed; plugins/memory 285 passed; live E2E against a real HTTP
token endpoint re-verified.
An init-time HonchoAuthError discarded the manager that recorded it, so
context/hybrid prefetch returned nothing and tools mode returned the
generic init error. The provider now keeps the failure detail across the
manager discard, prefetch emits the one-time notice at the readiness
guard, tools mode returns an explicit authentication error, and a
successful re-login retry clears the stored failure. Non-auth init
failures keep failing open with no notice.
_authed_call checks the dead-grant marker before calling, retries a
confirmed auth failure once after a forced refresh, and records the
failure for the one-time notice. Operations re-resolve their peer and
session objects inside the call, so a retry after a client rebuild no
longer reuses objects bound to the old transport. Tool handlers now
return an explicit auth error instead of an empty result, and non-auth
failures keep their fail-open behavior.
_is_auth_error matched the substring '401' anywhere in an error string,
so a latency figure ('retry after 4010 ms'), a request id, or a
workspace name containing those digits classified as an auth failure.
A false positive calls _force_reauth, which runs a real token exchange;
the server rotates the refresh token on every exchange, and a lost
rotation response leaves Hermes holding a superseded token whose later
replay revokes the whole grant — the exact wedge this branch fixes.
The status attribute check (SDK AuthenticationError carries status=401)
does the real work and stays first. A concrete non-401 status now wins
over ambiguous text. The text fallback keeps only specific markers:
'invalid or expired access token', 'authentication failed' (not bare
'authentication', which also matches auth-infrastructure outage
messages), 'unauthorized', and '401' only with HTTP context ('HTTP
401', 'status 401'), never as a bare number. The classifier is biased
toward false negatives: a missed auth error costs one un-recovered
call, a false positive spends a rotation.
Also redacts token values in _record_auth_failure, _auth_error_message,
and the two retry warnings, matching oauth.py. The SDK's auth errors
carry no token values today, but this is the one credential path where
an upstream regression would leak silently.
Tests: the four false-positive strings stay non-auth, HTTP-context 401s
still match, a concrete 429 status beats 'authentication failed' text,
and the recorded failure plus notice redact token values.
reauth_required() existed but nothing called it, so after a grant died
every dialectic fire and sync flush still sent a Honcho API call that
401ed. dialectic_query and _flush_session now check the dead-grant flag
first and skip the call: dialectic raises HonchoAuthError (exempt from
cadence backoff), sync returns False with the failure recorded so the
one-time notice still fires.
The check compares the on-disk refresh-token digest, so a re-login flips
it back with no network call and the next cadence resumes immediately.
Transient auth errors keep the existing force-refresh-and-retry path.
Four new tests: a dead grant issues no dialectic or sync call, and a
re-login resumes both without waiting.
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.
Review follow-up for salvaged PR #76782. Three setup-wizard
validation functions called _normalize_openviking_url outside their
try/except blocks. Since _normalize_openviking_url now raises
_OpenVikingEndpointError for blocked or malformed endpoints, an
invalid endpoint would crash the wizard instead of returning a
friendly (False, message) tuple.
- _validate_openviking_auth: move _normalize_openviking_url inside try
- _validate_openviking_root_access: same
- _validate_openviking_setup_values: catch _OpenVikingEndpointError explicitly
- Remove dead ternary in _normalize_openviking_url safety check (candidate
always has http/https scheme by that point)
- Replace redundant float('-inf') < x < float('inf') with math.isfinite()
in _setting_float; drop the redundant infinity check from _setting_int
(is_integer() already rejects inf/nan)
_recall_config() previously read all settings (recall_limit, score_threshold,
recall_resources, etc.) exclusively from environment variables. This forced
users to store behavioural configuration in .env, violating the Hermes
convention that .env is for secrets only.
The infrastructure to load config.yaml -> memory.openviking was already in
place via _load_hermes_openviking_config(), but _recall_config() never
called it.
Fix: call _load_hermes_openviking_config() and pass its values as the
default parameter to _env_int/_env_float/_env_bool. Env vars still override
config.yaml values, preserving backward compatibility.
Closes#62540
(cherry picked from commit 6aadf12568)
OpenViking is_available() only consulted env vars and use_ovcli_config, so an
endpoint saved to config.yaml (e.g. by the Dashboard) reported needs_config;
_resolve_connection_settings() likewise never folded config.yaml's non-secret
fields into its chain. RetainDB initialize() read base_url/project from the
environment only, ignoring the values the Dashboard writes to config.yaml.
Both now resolve non-secret fields as env -> (ovcli ->) config.yaml -> default;
secrets still come from the environment. Adds regression tests for both.
Fixes#68209
(cherry picked from commit dca57915b9)
`_committed_session_ids` is a permanent per-sid latch, and
`_session_needs_commit` checks it before the turn counter by design — a
racing sync_turn can re-increment `_turn_count` after commit+reset, so
the guard must win to stop a double-commit.
That is correct for a session being left behind. It is wrong for one
that keeps its id. `compress_context()` commits before rewriting the
transcript in both modes, and with `compression.in_place: true` (the
default) `on_session_switch` receives the same id and does not rotate.
The latch then rejects every later commit for a still-live session — the
next compression, /new, normal session end, startup recovery — so every
post-compression turn is silently never extracted.
Rotation mode is unaffected because a fresh child id is minted and
starts clean, which is what confirms the latch's intent was only ever to
dedupe the departing id.
Clear the latch when compression completes without rotation. Turns
arriving after that point are genuinely new, and this is a defined
moment rather than a race. The rotation path is untouched, so the old
id stays latched and its _finalize_session_async still dedupes against
the compression commit.
Fixes#74695
(cherry picked from commit d1e5c3dc33)
The provider used to disable OpenViking permanently when the server was
unreachable. That was fixed: `_ensure_client()` now reconnects lazily,
with a 30s cooldown gate in `_ensure_client_locked`.
Only one of the seven user-facing warnings was updated to match. The
other six still told the user memory was "disabled for this Hermes run",
which is no longer true — every one of those paths is retried on the next
access. A user who reads the old message has no reason to retry, which is
very likely how #5721 ("never recovers") came to be filed against
behaviour that already recovers.
All six sites were traced to confirm none is terminal for the run: the
`initialize()`-time and waiter-thread failures never arm `_failed_refresh`
(only line 2439 does), so they retry on the very next access with no
cooldown at all.
The replacement wording deliberately omits the "(after cooldown)"
parenthetical used at the already-correct site — that detail is only
accurate where `_failed_refresh` was just armed. The neutral phrasing is
true at all six.
Also promotes two clause separators to periods to avoid "…; …disabled;"
collisions.
(cherry picked from commit 8346403a4b)
`_start_local_openviking_server()` spawned `openviking-server`
unconditionally. Both callers — `initialize()` and the runtime
unreachable handler — reach it from a health probe, and that probe can
time out client-side while the server is up and serving. The spawned
process then loses the data-directory lock and exits immediately with
`DataDirectoryLocked`; because the probe keeps timing out, the cycle
repeats every cooldown window (~5 min observed).
The existing 30s `_failed_refresh` cooldown paces the loop but cannot
stop it, since it expires while the underlying condition persists.
Probe the target host:port before spawning and treat an occupied port as
already-started. This guards both call sites at their single convergence
point. The probe deliberately tests only that a listener owns the port —
enough to know a second server would lose the lock — and says nothing
about that listener's health.
The parse/probe now precedes the PATH lookup, so a reachable server is
reported as running even when `openviking-server` is not on PATH.
Fixes#74846
(cherry picked from commit b49427d85f)
## Summary
- Normalize OpenViking endpoints through `is_always_blocked_url` and fall back to the default local endpoint when poisoned.
- Keep intentional loopback / LAN self-host working.
- Add focused unit tests.
## Salvage / credit
Memory-provider endpoint floor sibling of RetainDB/Supermemory always-blocked hardening (avoids over-broad #4984-style private-IP bans).
(cherry picked from commit 8fa607d0ae)
Simplify-pass finding: sharing only the REGEX left the wrapper logic
(empty/strip/slash checks) duplicated, half-defeating the no-drift goal.
The classmethod now calls agent/memory_provider.is_trivial_prompt directly;
_TRIVIAL_PROMPT_RE stays as a class attr for backward compatibility with
any external referents.
Rebase fold on the salvaged gate:
- is_trivial_prompt/TRIVIAL_PROMPT_RE move to agent/memory_provider (the
ABC both the core gate and providers already import) — one source of
truth; honcho's _TRIVIAL_PROMPT_RE now aliases it, turn_context and the
queue_prefetch_all warm path (a sibling site main grew after the PR's
base) both use it
- tests: gate tests at the prefetch call site (mutation-checked), shared
classifier tests incl. prefix-collision guards (k8s/yolo/note/supper),
and honcho dialectic-machinery tests re-driven with a substantive prompt
("hello" became trivial by design — those tests exercise thread cadence,
not the classifier)
Salvage of PR #25350 (commits 88ffede2d + 2b848a0b2 + 3136dc63a, squashed
and ported): the run_agent.py prefetch site the PR gated has since moved
into agent/turn_context.py's build_turn_context(), so the trivial-query
gate lands there instead.
- Gate the per-turn memory_manager.prefetch_all() on a trivial-prompt
check so greetings/acknowledgements ('hi!', 'thanks', 'ok') no longer
block the turn on provider network round-trips or inject stale context.
- Extend honcho's _TRIVIAL_PROMPT_RE with greetings and a trailing
punctuation class so 'hey!' / 'hello.' classify as trivial.
- Add honcho classifier tests for greeting forms.
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.
Review follow-up on the #62871 salvage (simplify pass, HIGH):
1. Ops unresolved at the wait deadline were RETAINED in the pending set.
A permanently failing status endpoint (auth error, endless 500s, or a
server that loses ops without 404) would grow the set forever and make
EVERY later prefetch burn the full 10s budget re-polling it — and
prefetch()'s bounded 3s join sits on the reply path, so that money-quote
'adds no response latency' claim breaks. Timed-out ops are now dropped
(identical degradation to prefetch_waits_for_retain=False: possibly
stale recall) with a WARNING so persistent server trouble is visible.
Guard test mutation-checked (fails with eviction disabled).
2. Status polls now spaced 0.5s (was 0.05s shared with the local drain
poll): a wedged op cost up to ~200 get_operation_status round trips
per prefetch; now ~20 max over the default 10s budget.
Address PR #62871 review: with the default retain_async=True, aretain_batch
returns when the write is accepted, not when it's durable/recall-visible, so
draining the local writer queue (task_done) is not a read-after-write signal.
The next-turn prefetch could still recall before the just-completed turn was
observable on the server.
- Track the async operation_id/operation_ids returned by aretain_batch
- _wait_for_retains_drained now applies two ordered, budget-bounded barriers:
(1) local writer queue drains, then (2) tracked server-side async ops report
completion via operations.get_operation_status (an explicit read-after-write
condition). NotFound (completed+evicted) counts as done; transient errors
keep waiting until the deadline
- Completed ops are removed from the pending set so later prefetches don't
re-poll them; the whole wait stays off the reply path
- Add TestPrefetchServerRetainVisibility: op-id tracking (single/multiple),
no-op tracking when retain_async=False, prefetch waiting for server
completion before recall, timeout fallback on a wedged op, and NotFound /
transient-error status handling
Async retain already keeps the memory WRITE off the reply path (writes drain
on the single writer thread while the user gets their response immediately).
This closes the remaining retain/prefetch race: the next turn's warm prefetch
runs on its own thread and could recall BEFORE the just-enqueued retain write
lands, silently dropping the latest turn from recall.
- The background prefetch now waits (bounded) for pending retains to drain
before recalling, so warmed context includes the just-completed turn.
- The wait runs only on the background prefetch thread, never the reply path,
so it adds zero latency to the user's response and loses no writes.
- Bounded by prefetch_retain_drain_timeout (default 10s) and polls
unfinished_tasks so a wedged write can't hang the prefetch.
- New config keys: prefetch_waits_for_retain (default true),
prefetch_retain_drain_timeout (default 10.0).
When hrr_dim=1 the prefixed float32 blob (4+4=8 bytes) collides in
size with a raw float64 blob (1×8=8 bytes), making the format
discriminator in bytes_to_phases ambiguous — a legacy blob starting
with HRR1 would be misread as a prefixed float32 vector.
- phases_to_bytes now accepts an optional dim and falls back to
writing raw float64 when the two blob sizes are equal.
- bytes_to_phases prefers the legacy float64 interpretation when
sizes collide and dim is provided, since phases_to_bytes never
writes a prefixed float32 blob at dim=1.
- Three regression tests cover dim=1 write, round-trip, and the
legacy-prefix collision case.
Addresses hermes-sweeper review on PR #30499.
FactRetriever.search() re-encoded the query vector once per candidate,
related() re-encoded both role atoms once per fact row, and probe()
re-encoded the role-content atom once per row. All three encoders are
deterministic (SHA-256 counter blocks), so the hoisted vectors are
bit-identical to the per-iteration values they replace.
Measured (300-fact store, dim=1024, median of 30 calls): search()
11.62 -> 1.46 ms/call (8.0x; encode_text 30 -> 1 per call), related()
63.08 -> 16.17 ms/call (3.9x; encode_atom 601 -> 3 per call), probe()
431.93 -> 389.36 ms/call (1.1x; dominated by per-fact content encoding,
which is inherent to the algorithm and unchanged).
Tests: call-count regression tests for each hoist plus a bit-exact
parity test of search() against the pre-fix per-candidate loop.
The embedded Hindsight daemon's profile env file carries the plaintext
HINDSIGHT_API_LLM_API_KEY but was written via bare write_text(), leaving
it with umask-derived (typically world-readable) permissions.
- Create/truncate the file via os.open(..., 0o600); chmod a pre-existing
file to 0600 BEFORE writing new secret bytes.
- Post-write validation on POSIX: verify 0600, retry chmod, and raise if
the file still isn't owner-only.
- If validation fails, unlink the secret file so a plaintext key is never
left behind with unverified permissions.
- Regression tests under tests/plugins/ for fresh-write mode, tightening a
pre-existing 0644 file, and cleanup on validation failure.
Narrowed reimplementation of #74236 confined to plugins/memory/hindsight/;
the core utils.py atomic-replace opt-out from the PR was dropped.

The disease: ~15 scattered raw yaml.safe_load(config.yaml) reads that
silently miss managed-scope overlay, ${ENV_VAR} expansion, profile-aware
pathing, and root-model normalization. Every new config feature needed an
N-site sweep (incident chain 9cbcc0c9c8 → 732293cf87 → b0e47a98f9 →
1928aa0443). This commit assigns every raw read to an owner and adds a
lint-guard test so the class cannot regrow.
New primitive (additive-only change to hermes_cli/config.py):
read_user_config_raw(path=None) — reads the user file EXACTLY as
written; docstring states it is ONLY legal for write-back round-trips
and raw-file diagnostics. Behavioral reads must use
load_config()/load_config_readonly().
BEHAVIOR FIXES (class-a sites migrated to a canonical loader — these
previously read values that could DIFFER from the effective config):
gateway/run.py _try_resolve_fallback_provider → _load_gateway_runtime_config
keys: fallback_providers/fallback_model (provider, model, base_url,
api_key). Drift fixed: a managed-pinned fallback chain was ignored;
an api_key of "${OPENROUTER_API_KEY}" reached the resolver unexpanded.
gateway/run.py GatewayRunner._load_provider_routing → same loader
key: provider_routing. Drift fixed: managed-pinned routing prefs and
${VAR} templates were ignored.
gateway/run.py GatewayRunner._load_fallback_model → same loader
keys: fallback chain. Same drift as above.
gateway/run.py GatewayRunner._refresh_fallback_model
keeps the raw primitive (its last-known-good-on-parse-failure contract
forbids the fail-open loader, which returns {} on a torn write) but now
applies managed overlay + env expansion inline. Drift fixed: chain
edits under managed scope / env templates were previously frozen out.
tui_gateway/server.py _load_cfg (72 behavioral call sites)
now = raw read + managed overlay (pre-existing) + NEW ${VAR} expansion,
split from a new _load_cfg_raw() write-back primitive. Drift fixed:
e.g. custom_prompt: "hello ${VAR}", agent.system_prompt, model,
api_key/base_url templates reached sessions unexpanded. DEFAULT_CONFIG
is deliberately NOT merged (callers treat missing keys as unset;
`_load_cfg() == {}` sentinels and _save_cfg round-trips depend on it).
tui_gateway/server.py _profile_configured_cwd
keys: terminal.cwd of a NON-launch profile. Drift fixed: managed
overlay + ${VAR} expansion now apply (load_config() would resolve the
wrong profile's home, so the raw primitive + inline pipeline is used).
plugins/platforms/telegram/adapter.py _reload_dm_topics_from_config
→ load_config_readonly(). keys: platforms.telegram.extra.dm_topics.
Drift fixed: managed overlay + profile-aware pathing + expansion.
plugins/memory/holographic _load_plugin_config → load_config_readonly().
keys: plugins.hermes-memory-store.*. Same drift class.
WRITE-BACK ROUND-TRIPS (class-b: stay raw BY DESIGN via read_user_config_raw;
merging defaults/overlay would pollute the saved user file):
gateway/slash_commands.py: model persist x2, _save_gateway_config_key,
memory/skills write_approval toggles
gateway/platforms/yuanbao.py auto-sethome
tui_gateway/server.py _write_config_key + all cfg→_save_cfg blocks
(reasoning show/hide/full/clamp, details_mode[.section], prompt)
→ new _load_cfg_raw()
plugins/memory/holographic save_config
RAW-FILE DIAGNOSTICS + presence-sensitive bridges (class-c: stay raw,
now via the shared primitive with an explanatory comment):
hermes_cli/doctor.py x5 (model validation, stale-root-keys, .env drift,
deprecation sweep, memory-provider probe — the latter two keep their
inline managed overlay where they had one)
gateway/run.py _bridge_max_turns_from_config and the module-level
TERMINAL_*/HERMES_* env bridge (bridging merged defaults would export
all of DEFAULT_CONFIG into the environment; both keep their inline
overlay + expansion)
hermes_cli/send_cmd.py env bridge (same presence-sensitivity)
hermes_cli/gateway.py multiplex-conflict probe (reads the DEFAULT root's
config, not the active profile's — load_config is the wrong owner)
hermes_cli/profiles.py / hermes_cli/web_server.py / tools/wake_word.py
multi-profile reads (load_config targets only the ACTIVE profile home)
cron/jobs.py _resolve_default_model_snapshot and cron/scheduler.py
run_job config read keep their existing inline overlay+expansion but
now share the primitive (their fail-open + last-value semantics and
the deliberate no-defaults merge are preserved exactly).
Failure-semantics audit: every migrated site preserves its exact previous
behavior on missing file ({} / early return) and parse failure (raise into
the caller's existing except, warn, last-known-good, or fail-open) —
read_user_config_raw intentionally mirrors bare open()+safe_load semantics
(raises on parse errors, {} only on FileNotFoundError/non-dict root).
Guard: tests/hermes_cli/test_config_read_guard.py scans the tree for
yaml.safe_load within 6 lines of a 'config.yaml' reference outside an
explicit ALLOWLIST (hermes_cli/config.py, gateway/config.py, gateway/run.py
fallback path, hermes_cli/managed_scope.py which reads the MANAGED file,
gateway/readiness.py parse-health probe) and fails on new offenders.
E2E: tests/hermes_cli/test_config_loader_e2e.py runs a subprocess with a
temp HERMES_HOME (config.yaml containing ${E2E_PROMPT_SUFFIX}) plus a
HERMES_MANAGED_DIR overlay pinning agent.reasoning_effort, asserting
tui _load_cfg resolves "hello world"/"high" while _load_cfg_raw +
_save_cfg round-trip the template and user value verbatim with no
managed/default leakage.
Widen NS-605 to the two remaining direct-install sites in the hindsight
plugin, which still shelled out to 'uv pip install --python
sys.executable' and therefore failed (EROFS/EACCES) on immutable hosted
images with sealed venvs, and lost packages on redeploy:
- post_setup dependency install (~L835): install_specs() with ok /
blocked-reason / stderr handling matching honcho/mem0.
- initialize()-time hindsight-client auto-upgrade (~L1240):
install_specs(); blocked installs log the gate reason with the manual
command instead of a raw subprocess error, and init proceeds.
Audited every other memory plugin (supermemory, byterover, holographic,
openviking, retaindb) for direct pip/uv install subprocess calls: none
remain — their deps flow through plugin.yaml pip_dependencies or
lazy_deps.ensure().
Tests: TestClientAutoUpgradeRoutesThroughLazyDeps — upgrade goes through
install_specs with the exact spec (regression guard asserts no
subprocess.run), blocked upgrade is non-fatal and surfaces the gate
reason. Updated TestPostSetupEnvEncoding stubs to the new install path.
Installing a memory provider (Honcho, mem0, hindsight, ...) from the
dashboard Plugins page failed on hosted deployments with a permission
error: the setup endpoint shelled out to
`uv pip install --python sys.executable`, which targets the sealed
read-only venv under /opt/hermes (immutable hosted image, NS-579/#49113).
The correct mechanism already exists: tools/lazy_deps.py redirects
installs to the writable durable target on the data volume
(HERMES_LAZY_INSTALL_TARGET=/opt/data/lazy-packages) when the venv is
sealed (HERMES_DISABLE_LAZY_INSTALLS=1), appends the target to the END
of sys.path (core venv always wins collisions), and constrains shared
deps to core-venv versions. The dashboard installer simply never used
it.
Fix:
- tools/lazy_deps.py: new public install_specs() — installs arbitrary
manifest-declared pip specs through the same environment routing as
ensure(): venv-scoped by default, durable-target on sealed images,
refused with an actionable reason when gated off (config kill switch
or sealed venv without a target — never surfaces raw EROFS/EACCES).
Specs are validated with _spec_is_safe(); post-install it invalidates
import/metadata caches so availability rechecks in the same process
see the new packages without a restart. Never raises.
- hermes_cli/web_server.py: _install_memory_provider_pip_dependencies
now calls install_specs() instead of building its own uv/pip
subprocess. Blocked installs surface the gate reason in the setup
results; the response's status block reflects post-install
availability (stale 'missing deps' state clears immediately).
- hermes_cli/memory_setup.py, plugins/memory/honcho/cli.py,
plugins/memory/mem0/_setup.py: CLI setup wizards routed through
install_specs() too — same sealed-venv failure mode, same fix.
No hosted setup path writes to /opt/hermes anymore; provider discovery
and installation now use the same environment (sys.path activation is
shared with the lazy-install bootstrap in hermes_bootstrap).
Tests:
- tests/tools/test_lazy_deps.py: TestInstallSpecs — gating matrix
(sealed+no-target blocked with immutable-deployment reason, config
kill switch, sealed+target proceeds), spec-safety rejection before
any subprocess, venv-scoped vs --target command display, failure
stderr passthrough, never-raises contract.
- tests/hermes_cli/test_web_server.py: setup endpoint routes pip
through lazy_deps (regression guard asserts no direct 'pip install'
subprocess), blocked-reason surfacing, same-response availability
recheck clears stale missing state.
Fixes NS-605 (Plain T-1111).
gemini-2.5-flash shuts down Oct 16 2026 (Google deprecation schedule)
and gemini-3-flash-preview is superseded. Update every hardcoded
default to the current GA flash model:
- gemini_native_adapter: probe_gemini_tier + _create_chat_completion
default params; free-tier guidance de-pinned from a specific model's
RPD number so it doesn't stale again
- auxiliary_client: gemini/kilocode fallback aux models,
_OPENROUTER_MODEL, _NOUS_MODEL -> google/gemini-3.6-flash
(verified live on both OpenRouter and Nous portal /models)
- provider plugins: kilocode + vertex default_aux_model
- hindsight memory plugin: gemini provider default
- setup wizard gemini list: 3-flash-preview -> 3.6-flash (matches the
curated picker catalog)
- tests: aux-client assertions that pinned the old default literal now
reference the _NOUS_MODEL constant, so the next default bump can't
break them (change-detector cleanup)
Fixes#32360.
_check_local_runtime() only imported 'hindsight' and
'hindsight_embed.daemon_embed_manager', a strictly weaker import surface
than the embedded daemon actually needs: the daemon imports
sentence_transformers at startup (embeddings + reranker). When the
embedding stack is broken (e.g. a dependency conflict on a shared package
like huggingface-hub), the daemon can never start, yet is_available() and
'hermes memory status' still report Hindsight as available — every
retain/recall then fails silently.
Import sentence_transformers in the same probe so local/local_embedded
availability goes red with the real ImportError as the reason, letting
the agent degrade loudly instead of silently dropping memory. Local path
only; cloud mode is untouched and no network or model download is
triggered by the import.

The cherry-pick auto-resolution + AST sweep applied plain utf-8 at three
.env reader sites where the salvaged PRs (#62617, #62123) deliberately
use utf-8-sig — a Notepad BOM must not hide/duplicate the first key.
Restore the contract (tests pin it).
AST-driven pass over every Path.read_text()/write_text() without an
explicit encoding= across non-test code: 71 sites in 34 files
(skills_hub, hermes_cli/main+profiles+service_manager+container_boot,
mem0/hindsight/honcho plugins, achievements dashboard, release/CI
scripts, productivity+comfyui skill helpers, agent/*). Verified zero
positional-encoding collisions before insertion; per-file compile()
check after.
Adds a check-windows-footguns rule flagging bare single-line
read_text/write_text (multi-line forms stay covered by the AST guard
test from #38985). Together with the salvaged contributor commits this
retires the ~169-site bare file-I/O class (#37423's long tail).
Follow-up to review feedback:
- mem0 _prompt_api_key read .env with the locale default, so a Notepad
BOM hid the first key from the masked current-value lookup; read it
with utf-8-sig + errors=replace like the canonical readers in
hermes_cli/config.py.
- hindsight _load_simple_env used plain utf-8; it also parses the Hermes
.env during post_setup, where a BOM stuck to the first key. Switch to
utf-8-sig + errors=replace.
- Add hindsight regressions: BOM key matching in _load_simple_env and in
the cloud post_setup writer, plus non-ASCII round-trip preservation,
and a mem0 regression for the BOM'd masked-key lookup. The BOM tests
fail without the fix on any platform.

The mem0 and hindsight memory-provider setup routines round-trip the
user's ~/.hermes/.env: they read existing lines, update the keys they
manage, and rewrite the whole file preserving every other line verbatim.
Both used env_path.read_text() / write_text() with no encoding.
read_text()/write_text() with no encoding fall back to the system locale
(cp1252/GBK on Windows), so on a non-UTF-8 host the preserved lines get
mangled or the call crashes on any non-ASCII value, and — because the
reader never strips a BOM — a Notepad-edited .env makes the first key
fail the in-place match and get duplicated instead of updated.
Match the canonical .env readers in hermes_cli/config.py: read with
encoding='utf-8-sig' (BOM-tolerant) and write with encoding='utf-8'.
mem0/_setup.py already pins utf-8 for mem0.json, so this just aligns the
.env path in the same file. Fixes both memory plugins in one class fix.
Adds regression tests: a BOM'd .env updates the first key in place
(locale-independent, fails without the fix) and non-ASCII existing lines
survive the round-trip.

On Windows with CJK locales (e.g. Chinese/GBK), pathlib.Path.read_text()
defaults to the system encoding instead of UTF-8, causing UnicodeDecodeError
when reading .env or .json config files that contain non-ASCII characters.
Explicitly pass encoding='utf-8' to all read_text() and write_text() calls
in the hindsight memory provider plugin.
Path.read_text() without an explicit encoding uses the platform's
default encoding. On Windows this is typically cp1252 or mbcs, which
causes UnicodeDecodeError or silent data corruption when reading
UTF-8 content (JSON files, user text, config with non-ASCII chars).
This is the read-side companion to the write_text() encoding fix.
Fixed the most critical locations that read JSON data, user content,
and config files across 14 files with 31 call sites.
Pattern: .read_text() → .read_text(encoding='utf-8')
json.loads(path.read_text()) → json.loads(path.read_text(encoding='utf-8'))
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.
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

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.
