The prior assertion `all("turn1" in k or "turn2" in k for k in keys)` was
weak on two counts: it passes vacuously when keys is empty (a regression
that lost all state would slip through), and after turn 2 finalizes only
turn 1 lingers, so it only ever inspected turn 1 anyway. Replace it with an
exact check that one key survives, it is turn 1, and turn 2 never merged
into it — the real isolation invariant the test name claims.
Scoping the trace key by turn_id (the prior commit) fixed cross-turn
collisions but introduced a slow leak: _finish_trace only pops a key when a
turn ends cleanly (final response has content and no tool calls), so any
turn that is interrupted, ends on a tool call, or has empty final content
now leaves its uniquely-keyed entry in _TRACE_STATE forever. Previously the
constant per-session key was overwritten by the next turn, capping growth at
~1 entry per session.
Add an LRU cap (_MAX_TRACE_STATE) enforced by _evict_stale_locked, called
under _STATE_LOCK immediately before each insert. It evicts the
least-recently-updated entries (using the previously-dead last_updated_at
field) and ends their root span so nothing dangles. Regression test drives
50 non-finalizing turns against a cap of 8 and asserts the dict stays bounded
with the most-recent turns surviving.
The turn- and api-scoped branches each repeated the same
task/session/thread fallback ladder with only the infix differing. Extract
the shared prefix into _scope_prefix so a future scope dimension touches one
ladder instead of three. The legacy branch still returns a bare task_id (not
the task: prefix) for backward compatibility, so it stays separate.
Output key strings are unchanged; a new test pins them across every
task/session/turn/api combination since the keys are matched across hooks
and any drift would silently break trace finalization.
The PR added helper-level tests for _trace_key but nothing exercised the
keys through the real hooks. This adds TestTurnTraceIsolation, which drives
on_pre_llm_request / on_post_llm_call across two turns of one gateway
session (task_id == session_id, unique turn_id, api_call_count reset per
turn) and asserts each turn opens its own root trace when the first turn
fails to finalize (tool-only final step). This test fails on the pre-fix
code (only one trace opened, turn 2 absorbed into turn 1) and passes with
the scoping fix.
Also pins the turn_id-over-api_request_id key precedence: the turn-scoped
post_llm_call carries no api_request_id, so it must still resolve to the
same key as the request-scoped hooks or finalization breaks.
Resolves conflicts from the OpenViking churn that merged after #32445 was
opened (#48042/#47662 session-switch + write hardening, #47311/#47973):
- plugins/memory/openviking/__init__.py: keep both __init__ field groups
(the PR's _runtime_start_* alongside main's _prefetch_threads/_shutting_down).
- tests/plugins/memory/test_openviking_provider.py: keep BOTH the PR's new
setup-validation tests and main's session-switch/concurrency tests (disjoint
additions to the same region).
Two fixes layered while reconciling (contributor work otherwise preserved):
- Restore the merged tenant-header contract (#22414/#21232). The PR had changed
_VikingClient defaults to '' and made empty account/user OMIT the tenant
headers; main's contract is that empty falls back to 'default' and the
X-OpenViking-Account/User headers are ALWAYS sent (ROOT API keys need them).
Reverted the constructor to 'account or os.environ.get(..., "default")' and
updated the two PR tests that asserted the omit-when-empty behavior.
- Close a secret-file TOCTOU in the setup writers. _write_env_vars and
_write_ovcli_config wrote the api_key/root_api_key file and chmod 0600
AFTERWARD, leaving a world-readable window on newly-created files. Added
_precreate_secret_file() to create with 0600 before any secret bytes land.
Phase 4E (E.1 + E.2). The inbound side of Chronos: NAS POSTs the agent when a
one-shot fires; the agent verifies a NAS-minted JWT and runs the job.
E.1 — plugins/cron/chronos/verify.py:
- verify_nas_fire_token(token, expected_audience, jwks_or_key, issuer): verifies
signature against the NAS JWKS (RS/ES family; symmetric rejected), aud == this
agent, exp/nbf, iss, and purpose == "cron_fire" (so a general agent JWT can't
be replayed against the fire endpoint). Returns claims or None; never raises.
Crypto delegated to PyJWT[crypto] (already a declared dep) — no hand-rolled
JWT, no new dependency. No key configured → refuse (never unsigned-decode a
security boundary).
- get_fire_verifier(): pluggable indirection so the DQ-4 escape hatch
(direct per-job cron-key) can swap in with no handler change.
E.2 — gateway/platforms/api_server.py:
- POST /api/cron/fire (registered only when _CRON_AVAILABLE). Authenticated by
the NAS-JWT via get_fire_verifier() — NOT API_SERVER_KEY (NAS holds no API
key; this is the only inbound that triggers remote job execution, so it gets
its own purpose-scoped check). Verifier args come from cron.chronos.* config.
401 on bad/missing/forged token. 400 on missing job_id. On success: 202 +
fire_due runs in the background (so a long agent turn never trips NAS's HTTP
timeout); the store CAS claim inside fire_due de-dupes a scheduler retry.
Tests:
- test_chronos_verify (11): REAL RS256 signing — valid→claims, wrong-aud,
missing/wrong purpose, expired, wrong-iss, tampered-signature (attacker key),
no-key-refuse, empty-token, JWKS-URL key resolution, get_fire_verifier.
- test_cron_fire_webhook (5): valid→202+fire, invalid→401+no-fire, missing
token→401, missing job_id→400, and fire path does NOT require API_SERVER_KEY.
api_server regression suites (214) green.
E.3 (NAS endpoints) is a separate cross-repo PR; the wire contract lands next
(docs/chronos-managed-cron-contract.md).
Phase 4D. The first non-default CronScheduler: plugins/cron/chronos/. Inert
unless cron.provider=chronos; resolve_cron_scheduler falls back to the built-in
if unavailable, so cron never loses its trigger.
Files:
- chronos/__init__.py — ChronosCronScheduler + register(ctx).
* is_available(): config-only, NO network (portal_url + callback_url + a
stored Nous access token via get_provider_auth_state). Returns False →
resolver falls back to built-in.
* start(): reconcile() then RETURN — no blocking loop, no 60s wake (DQ-1:
this is what makes scale-to-zero real; the machine wakes only on a
NAS→agent fire).
* _arm_one_shot(job): POST NAS provision {job_id, fire_at, agent_callback_url,
dedup_key=job_id:fire_at}. Agent owns the time → sub-minute fires survive
(no scheduler 1-minute floor).
* reconcile(): converge NAS arms toward jobs.json — arm missing/changed-time,
cancel orphaned, skip paused. Cold process rebuilds from jobs.json +
idempotent dedup_key.
* on_jobs_changed(): reconcile (re-arm/cancel the affected one-shot).
* fire_due(): ABC default (CAS claim + run_one_job) THEN re-arm the next
one-shot. Job gone (one-shot done / repeat-N exhausted) → no re-arm.
- chronos/_nas_client.py — thin HTTP wrapper for provision/cancel/list using
the agent's existing refresh-aware Nous token (resolve_nous_access_token).
Names no scheduler vendor; holds no scheduler creds.
- chronos/plugin.yaml — discovery metadata.
INVARIANT: zero "qstash"/"upstash" hits in plugins/cron, gateway, hermes_cli,
website/docs — the external scheduler is a NAS-internal detail, never named
agent-side.
Tests (13, all NAS mocked, zero network): is_available off-without-config +
on-with-config + makes-no-network; arm payload incl. sub-minute + noop without
next_run; reconcile arms-all / cancels-orphan / skips-paused / skips-already-
armed; fire_due re-arms next / no re-arm when job gone / no re-arm when claim
lost.
* fix(photon): preserve text in mixed iMessage attachments
When an iMessage bubble carried both text and an attachment, spectrum-ts'
inbound mapper returned only buildAttachmentMessage(...), dropping the user's
typed text before Hermes could see it. The Photon adapter then had no 'group'
content path, so the text was lost entirely.
- adapter.py: handle a new 'group' content type that flattens text + attachment
items, preserving the typed text alongside cached media (extracted shared
_normalize_binary_payload helper).
- sidecar: emit 'group' content in normalizeContent, and ship
patch-spectrum-mixed-attachments.mjs which patches spectrum-ts' pinned mapper
(at npm postinstall AND at sidecar startup, so existing installs self-heal).
Windows robustness fixes on top of the original PR:
- The patcher's CLI guard used 'import.meta.url === file://${argv[1]}', which
never matches on Windows (file:/// + drive letter) — it silently no-opped.
Switched to pathToFileURL(argv[1]).href.
- The patcher matched \n-joined strings, so a CRLF checkout (Windows git
autocrlf) defeated every replacement. It now normalizes CRLF->LF for matching
and restores the original EOL style on write.

Follow-up hardening on @ehz0ah / @harshitAgr's session-switch work (#28296):
- on_session_switch no longer runs the old-session writer-drain + pending-token
GET + commit POST inline on the caller's command thread. /new, /branch,
/resume, /undo call it synchronously, so a slow drain (up to 10s) or wedged
commit blocked the user-facing command — the same hazard #41945 fixed for
end-of-turn sync. State now rotates synchronously (cheap) and the old-session
commit is offloaded to a daemon finalizer (generalized _finalize_session_async).
- Guard the (_session_id, _turn_count) pair with _session_state_lock: sync_turn
runs on the memory-manager executor thread while the session hooks run on the
command thread, so the snapshot+reset vs increment was a cross-thread race.
- _session_needs_commit checks the committed-session guard BEFORE the
turn_count>0 shortcut, closing a double-commit window when a racing sync_turn
re-increments after commit+reset.
- Add a _shutting_down flag so deferred finalizers stop POSTing against a
torn-down client; track all prefetch threads in a set so invalidate/shutdown
join every one, not just the latest slot.
Tests: regression for the non-blocking switch (asserts the caller returns while
a slow drain is parked off-thread) and the committed-guard ordering; updated the
deferred-commit test to the unified finalizer contract.
sync_turn's bounded join could drop a still-alive previous worker by
replacing the single _sync_thread slot. The dropped worker kept POSTing
under the old sid but was no longer visible to on_session_end /
on_session_switch, so the commit could fire while orphaned writes were
still in flight — those writes landed past the commit boundary and were
never extracted.
Replace the single _sync_thread slot with _inflight_writers:
Dict[sid, Set[Thread]]. Writers self-register on spawn (sync_turn,
on_memory_write) and self-deregister on exit. The commit path drains
_drain_writers(sid, 10.0) and skips the commit if any writer for that
sid is still alive after the bounded budget.
Also trim inline review-rationale comments to short invariants per
reviewer style ask: "commit only after session writes drain" and
"drop prefetch results from older switch generations."
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
(cherry picked from commit 7537ee6f5b)
Three follow-ups from review on #28296:
1. Sync worker outliving the bounded join. Each sync_turn POST has
_TIMEOUT=30s and there are two per turn, but on_session_end and
on_session_switch only join for 10s. If the worker is still alive
after the join, committing the old session orphans the worker's
late writes past the commit boundary — they land in an already-
committed session and never get extracted. Both hooks now re-check
is_alive() after the join and skip the commit when the worker
hasn't drained.
2. on_memory_write late session_id capture. Same shape as the
pre-fix sync_turn: f-string for the post path read self._session_id
inside the worker, so a switch between thread spawn and post call
landed the memory note in the new session. Snapshot sid at call
time, same pattern as sync_turn.
3. Stale prefetch repopulating the new session. The pre-switch
drain+clear only protects against workers that finish before the
join completes; one finishing after the clear would write its
result into the new generation's slot. Added a monotonic
_prefetch_generation; workers capture it at spawn and refuse to
write if it has advanced.
Tests: existing in-flight-sync test updated to drain (it tested the
join-before-commit happy path); four new tests cover hung-writer skip
on end + switch, on_memory_write sid capture, and prefetch generation
gating. 177/177 memory tests pass.
(cherry picked from commit 3791a87dbe)
Two hardening fixes prompted by review on #28296:
1. sync_turn() now snapshots the target session id before spawning the
worker. The previous code read self._session_id inside the worker, so
a worker delayed past on_session_switch's bounded join could read the
rotated-in NEW id and write the OLD turn's messages into the wrong
session.
2. on_session_end() resets _turn_count to 0 after a successful commit,
making the old-session commit path idempotent with the new switch
hook. /new and compression call commit_memory_session() (which fires
on_session_end) immediately before on_session_switch; without this,
the old session would be committed twice. On commit failure we leave
_turn_count > 0 so on_session_switch retries.

(cherry picked from commit 2ea8d5c537)
OpenVikingMemoryProvider only overrides on_session_end and inherits the
base-class no-op for on_session_switch. When the agent rotates session_id
(via /new, /branch, /reset, /resume, or context compression), the
provider's cached _session_id stays at the value initialize() captured.
All subsequent sync_turn writes then land in the already-closed old
session, and on_session_end tries to commit it a second time — the new
session never accumulates messages and never triggers memory extraction.
The fix mirrors the pattern Hindsight uses (#17508):
1. Wait for any in-flight sync thread to drain under the OLD _session_id
before we mutate it, otherwise the commit below races the last
message write.
2. Commit the old session if it accumulated turns — same extraction
semantics as on_session_end. Skip if empty (nothing to extract).
3. Drain in-flight prefetch from the old session and clear its cached
result so the new session doesn't see stale recall.
4. Rotate _session_id to the new value and reset _turn_count.
Commit failures are swallowed (logged at WARN) so a flaky server can't
strand the provider on the old session forever — same posture as the
existing on_session_end commit.
(cherry picked from commit a1e7185e8a)
Support linking, copying, and creating ovcli.conf during OpenViking memory setup.

Adds an observation_scopes config key (and HINDSIGHT_RETAIN_OBSERVATION_SCOPES
env var) so retained memories can opt into per_tag / all_combinations /
custom scoping instead of Hindsight's default combined pass.
Threaded through _build_retain_kwargs so all three retain paths honor it:
auto-retain and flush-on-switch already use aretain_batch; the tool retain
path is switched from aretain to aretain_batch (functionally equivalent,
aretain just wraps a single-item batch) since aretain doesn't accept the
observation_scopes parameter.
Remove the free Parallel Search MCP path and restore the keyed Parallel backend behavior from before it was introduced.
Also drops the keyless fallback registration/display labeling tests and returns the Parallel SDK pin to the prior version.
A hard gateway exit (crash, SIGKILL, supervisor restart) left the
detached Node sidecar running with a token the next gateway run doesn't
know, so it could never be told to /shutdown. Every replacement spawn
then died on EADDRINUSE, failing each 30→300s reconnect attempt while
the orphan kept consuming the inbound gRPC stream.
Two layers:
- Lifetime binding: the adapter now holds the sidecar's stdin as a
pipe, and the sidecar (PHOTON_SIDECAR_WATCH_STDIN=1) shuts down on
stdin EOF — fired by the OS on any parent death, including SIGKILL.
- Startup reaping: before spawning, the adapter probes the port and
terminates a stale listener, but only after verifying its command
line is a Photon sidecar; a foreign listener raises a clear error
instead of being signalled.

Pin spectrum-ts to exactly 3.0.0 (was ^1.18.0 plus an `npm install
spectrum-ts@latest` on every setup) so breaking SDK majors can't take
down fresh installs silently; `hermes photon setup` now runs `npm ci`.
Upgrade procedure documented in the README.
Migrate resolveSpace to the v3 namespace API: `im.space.create(phone)`
for DMs and `im.space.get(id)` for everything else — group spaces are
now rehydratable from their persisted id after a sidecar restart, which
v1 could not do.
Markdown: replies go out via the v3 `markdown()` builder (iMessage
renders natively; other Spectrum platforms degrade to plain text).
`PHOTON_MARKDOWN=false` reverts to the stripped plain-text path.
Reactions, behind PHOTON_REACTIONS (default off): lifecycle tapbacks
(👀 while processing, 👍/👎 on completion) via new sidecar /react and
/unreact endpoints with per-target reaction-handle tracking, and user
tapbacks on bot-sent messages routed to the agent as synthetic
`reaction:added:<emoji>` events.

* fix(discord): recover from runtime gateway task exits
Salvaged from #39416 (AMEOBIUS) — cherry-picked only the task-exit
recovery; the original PR was 1081 commits behind with 28 unrelated
commits.
A post-ready discord.py WebSocket crash left the gateway split-brained:
producers stayed active while Discord stopped responding. After this fix
the adapter calls _set_fatal_error(retryable=True) + _notify_fatal_error()
so the existing GatewayRunner reconnect watcher replaces the dead adapter.
Also adds _wait_for_ready_or_bot_exit() so startup failures (SOCKS/proxy
errors, invalid tokens) surface fast instead of burning the full ready
timeout. Because connect() no longer waits via asyncio.wait_for on that
path, test_connect_releases_token_lock_on_timeout is updated to trigger
the timeout through the new helper (same lock-release contract).
3 tests pass (2 new runtime-failure tests + the updated timeout test);
test_discord_connect.py and test_discord_slash_commands.py green.

Replace the hermes-identifying clientInfo/User-Agent/session-id prefix on
the keyless Parallel Search MCP path with a neutral 'mcp-web-client'
identity. Project policy forbids third-party usage attribution without an
explicit user opt-in (see telemetry PR policy); MCP requires a clientInfo,
so a generic one satisfies the spec without attributing traffic.
Also adds the contributor AUTHOR_MAP entry and refreshes uv.lock against
current main (parallel-web 0.6.0).
Make Parallel the web search/extract backend with a zero-setup free tier:
- Keyless (no PARALLEL_API_KEY): web_search/web_extract work out of the box via
Parallel's free hosted Search MCP (search.parallel.ai/mcp), and parallel
becomes the default backend when no other web credentials are configured
(ahead of ddgs, which is search-only). A small hand-rolled Streamable-HTTP
JSON-RPC client speaks the MCP's web_search/web_fetch tools; the existing
web_search/web_extract tools are the only tools registered.
- Keyed (PARALLEL_API_KEY set): uses the Parallel v1 REST endpoints
(client.search / client.extract with advanced_settings.full_content) — no beta.
Bumps parallel-web 0.4.2 -> 0.6.0.
- Attribution: on the free path only, results carry provider/attribution and the
CLI tool line reads "Parallel search" / "Parallel fetch"; the paid path is
unbranded.
- Selection/registration: web tools register unconditionally (free MCP backstop)
while check_web_api_key remains a real usability probe; explicit per-capability
backends are honored (so misconfig surfaces) rather than masked by the fallback.
Tested: live web_search/web_extract against search.parallel.ai in keyless and
keyed modes; unit suites for the MCP client, backend selection, and display
labeling; full agent run shows the "Parallel search" label on the free path.
The Langfuse SDK treats `data:*;base64,...` strings as media and tries to
decode them. `_truncate_text` was slicing those strings mid-payload, producing
invalid base64 and noisy "Error parsing base64 data URI" logs. Observability
only needs the metadata, not raw image/audio bytes, so redact the whole data
URI (type, media_type, length) before it reaches the SDK.
Salvaged the Langfuse fix from #39682 onto current main as a standalone,
single-concern change (the dashboard `dist/**` and plugin-discovery parts of
that PR already landed separately on main).

* fix(photon): override transitive CVEs in the sidecar deps
`npm audit` flagged 7 high-severity transitive CVEs (protobufjs code injection
GHSA-66ff-xgx4-vchm + outdated @opentelemetry OTLP exporters) pulled in via
spectrum-ts -> @photon-ai/otel. npm's suggested fix downgrades spectrum-ts to a
version that targets the decommissioned spectrum host, so instead pin patched
versions via `overrides` (protobufjs 8.6.1, @opentelemetry/* 0.218.0) without
touching spectrum-ts. `npm audit` -> 0; spectrum-ts + provider still import.
* fix(photon): harden the sidecar bridge + bound the dedup cache
- constant-time sidecar control-token comparison (was `!==`, timing-attackable).
- cap the control-channel request body (2 MiB) so a compromised local peer can't
OOM the sidecar.
- wrap the inbound gRPC stream consumer in a re-subscribe loop with capped
exponential backoff + jitter — if the async iterator throws/ends it would
otherwise stop inbound forever (the adapter dedupes any replay).
- add an unhandledRejection handler so a stray rejection logs instead of killing
the process.
- dedup cache (adapter) was a true bounded LRU only for expired entries; a burst
of unique ids within the window grew it without limit. Evict oldest at the cap.

Based on #42658 by @mnajafian-nv.
Preserves the real downstream provider/tool exception when NeMo Relay's
managed adaptive execution wraps a failing callback as an internal runtime
error. Without this, the original exception (and its retry-classification
signal, e.g. status_code) is lost behind Relay's wrapper.
Salvage changes on top of the original PR:
- Tolerant Relay-wrapper match: _is_relay_wrapped_callback_error now uses
str.startswith on the "internal error: <cls>: <msg>" prefix instead of
exact equality, so a future Relay version appending a traceback/suffix
doesn't silently defeat the unwrap. On a total format change it returns
False and falls back to the pre-fix behavior (surfacing Relay's error)
rather than masking it.
- Deduplicated the LLM and tool execute paths into a shared
_run_managed_with_downstream_preservation helper, removing ~20 lines of
copy-pasted nonlocal/try-except scaffolding that could drift out of sync.
- Added a real-middleware regression guard
(test_nemo_relay_downstream_unwrap_matches_real_middleware_wrapper_shape)
that drives hermes_cli.middleware._run_execution_chain and asserts the
plugin's _original_downstream_error unwraps the actual private
_DownstreamExecutionError wrapper. The original synthetic tests modeled the
wrapper with a local class, so a rename or shape change in core middleware
would not have been caught; this test fails loudly if that contract drifts.

Extend the sidecar and Python adapter to handle `voice` content
alongside `attachment`. Voice notes are inlined as base64 (same
size-cap logic), surfaced as `MessageType.VOICE`, and include an
optional `duration` field in fallback markers when bytes are
unavailable.
