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)
Review feedback: the previous test called _mark_session_committed
directly, so it verified the guard's behavior but not the wiring that
sets it — a future break in the commit_memory_session -> same-id
compression-boundary path would not be caught.
Add a lifecycle regression that drives the real sequence: on_session_end
commits through the actual path, on_session_switch(same id,
reason="compression") crosses the boundary, sync_turn records a genuinely
new turn, and a second on_session_end must produce a second commit POST.
Without the fix it fails showing exactly one commit call, which is the
reported data loss: every turn after the first compression is dropped.
The rotation and /undo tests stay as scope guards.
(cherry picked from commit 0ca5a33063)
`_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)
Two bugs reported by gfdsa (PR #41711 comment, Jul 12) that break the
official a2a-sdk 1.1.0 Python client:
1. Task objects serialized non-spec createdAt/lastModified fields.
The A2A v1.0 Task proto (lf.a2a.v1.Task) only has id, contextId,
status, artifacts, history, metadata. Strict ProtoJSON parsers
reject unknown fields with ParseError. Removed both fields from
build_task(); created_at param kept for call-site compatibility.
2. SSE streaming frames were not JSON-RPC wrapped. A2A v1.0 §9.4
requires data: {"jsonrpc":"2.0","id":...,"result":{StreamResponse}}.
sse_data() now accepts req_id and wraps in JSON-RPC envelope.
sse_done() changed from 'data: {}' to SSE comment ': done' so
SDK doesn't try to parse an empty JSON-RPC response.
All call sites in adapter.py (_emit_terminal, _rpc_message_stream,
_rpc_tasks_subscribe) updated to thread req_id through.
Tests updated: 153 pass (151 unit + 17 integration, including 2 new
tests for JSON-RPC envelope wrapping and fallback behavior).
Refs: gfdsa/a2a-hermes reproduction repo
## File/data Parts (v1.0 unified Part)
- file_part(url=, raw=, filename=, media_type=) builds v1.0 file Parts
- data_part(data, media_type=) builds v1.0 data Parts
- message_with_parts(role, parts, context_id=) builds Messages with mixed Part types
- extract_text now renders file/data Parts into the text stream:
- File with URL: '[file: name] https://url (mediaType)'
- File with raw: '[file: name] N bytes base64-encoded (mediaType)'
- Data: '[data (mediaType)]\n{json}'
- v0.3 file (file.fileWithUri) and data (kind=data) still accepted
- Outbound replies stay text-only (agent produces text)
## Push notification config full CRUD
- get_push_config(task_id, config_id) — retrieve by task, optionally by configId
- list_push_configs(task_id) — list all configs for a task (max 1 per task)
- delete_push_config(task_id, config_id) — remove a config
- New JSON-RPC methods: tasks/pushNotificationConfig/get, /list, /delete
- New adapter handlers: _rpc_push_config_get, _list, _delete
- All return spec-shaped PushNotificationConfig with configId + createdAt
## Tests
- 6 new unit tests for Part builders + extract_text with file/data
- 13 new unit tests for push config get/list/delete (happy + error paths)
- 2 new integration tests over real HTTP:
- test_mixed_parts_delivered_to_agent: file URL + data JSON reach agent
- test_push_config_crud_over_http: full create→get→list→delete cycle
- Old test_extract_text_skips_non_text_parts replaced (now renders, not skips)
Total: 151 tests (134 unit + 17 integration), 0 failed.
DESIGN.md updated: file/data Parts and push config CRUD removed from
out-of-scope list.
Consolidates 5 follow-up PRs onto the a2a-work branch:
1. Reply-capture fix (#56437): adapter.send() now only resolves the
blocked RPC Future when metadata['notify'] is True (the gateway's
final-reply marker). Interim sends no longer short-circuit the
response. Also accepts **kwargs in connect() for reconnect compat.
2. Slash command passthrough (#53743): wrap_inbound() passes /-prefixed
text through unwrapped so the gateway command processor sees it.
Fixes /sethome deadlock during A2A onboarding. Documented security
trade-off (bearer auth at network layer compensates).
3. Routable URL in Agent Card (#53736): _build_card() now derives URL
from A2A_PUBLIC_URL env > X-Forwarded-Host/Host header > bind host.
Fixes k8s bug where Agent Card advertised 0.0.0.0.
4. contextId multi-turn memory (#53756): _handle_inbound_task() now
checks top-level params.contextId first (A2A spec), falls back to
params.message.contextId (legacy). Outbound a2a_call also sends
contextId at both top-level and inside message.
5. Type checker fixes (#53759): TypedDict for _SCHEMAS, _FunctionSchema,
_ToolSchema. Removes str() band-aid casts.
All 45 tests pass including new tests for each fix.
Zero core files modified — only plugins/platforms/a2a/ and tests/.

report), @shivasymbl (#45996 userContext OBO).
Live Tier-3 testing (CLI agent -> a2a tools -> live peer gateway -> model)
surfaced two bugs the kwarg-style unit tests masked:
1. registry.dispatch calls handlers as handler(args, **kwargs) — args is the
whole dict positional. The handlers used keyword params (url=, agent=), so
the dict bound to the first param and .strip() raised
'dict object has no attribute strip'. Rewrote all three handlers to take
args: dict (matching the spotify/google_meet convention). Added a
registry-dispatch regression test that exercises the real call path the
direct-kwarg tests never hit.
2. The model repeatedly reached for agent_name= instead of agent= (6 retries
before success). Accept agent_name/name and message/text/task aliases so a
reasonable guess succeeds first try.
Verified live: client agent discovers the peer's Agent Card, calls it, and
gets the reply back (PONG round-trip confirmed on both client audit log and
peer conversation log). 39 plugin tests pass.
Single platform-adapter plugin under plugins/platforms/a2a/ — zero core
edits — that supersedes the entire A2A PR/issue cluster. Built on the
ctx.register_platform + ctx.register_tool surface the codebase now exposes.
Outbound (a2a toolset): a2a_discover / a2a_call / a2a_list let the agent
call any A2A-compliant peer over JSON-RPC message/send. Inbound (platform
adapter): a stdlib http.server serves an Agent Card at
/.well-known/agent.json and routes incoming tasks into the agent's LIVE
gateway session (the #11025 insight) — same agent, full memory — returning
the reply over A2A.
Security on by default: no bearer token => 127.0.0.1-only bind; constant-
time bearer auth; inbound prompt-injection filtering + untrusted-peer
framing; outbound credential redaction; append-only audit log; per-context
conversation persistence outside the compaction pipeline.
Stdlib only (no a2a-sdk). 37 tests incl. a live HTTP round-trip
(card + message/send + reply) and a bearer-auth 401 path.
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.
Review follow-up on the #76142 salvage: MemoryStore path-resolves and
shares one process-wide connection per file, so MemoryStore(":memory:")
creates a literal ./:memory: FILE whose state leaks across test runs —
the second run of the file failed all three spy tests because the
NULL-vector test had permanently wiped hrr_vector in the leaked db.
tmp_path isolates each run; verified two consecutive runs green + full
tests/plugins/memory/ green.
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.
Carries the new column through create, PATCH, and bulk. Clearing is an
explicit clear_reasoning_effort flag rather than a null, because a null in a
PATCH body means "field not sent", not "set to NULL" — the same shape the
model override already uses, and the reason "none" can stay a real value.
Tests cover normalization, the depth-survives-a-model-clear invariant, both
spawn-argv branches, and the REST round-trip. One asserts the worker CLI
actually accepts the --reasoning flag the dispatcher emits: a spawn arg no
parser accepts would fail every dispatch while every unit test stayed green.
CI's plugin-test slice runs without the discord optional extra; the raw
import failed with ModuleNotFoundError while every other test in the
file uses injected mock modules.
Under gateway.multiplex_profiles, Discord and Telegram authorization gates
(allowed/ignored channels, allowed users/roles, allow-all flags) were read
from process-global os.environ, populated first-writer-wins by the YAML->env
bridge in each adapter's _apply_yaml_config. The first profile to initialize
pinned its allow/deny lists — and its ALLOW_ALL flags — for every other
profile in the process (issue #72348, incl. the Telegram mirror reported in
the thread).
Fix (per-adapter-instance gate reads, whole class):
- gateway/authz_mixin.py: new _platform_gate_env — scope-authoritative gate
read: under an installed profile secret scope with multiplex active, a
missing key returns the default instead of falling through to os.environ
(which may hold another profile's value). Single-profile behavior is
byte-identical to os.getenv.
- Discord adapter:
- connect() snapshots all gate env vars (_GATE_ENV_KEYS) inside the owning
profile's runtime scope into a per-adapter dict; new accessors
(_get_allowed_channels/_get_ignored_channels/_get_allowed_users/
_get_allowed_roles/_get_no_thread_channels/_discord_allow_all_users/
_gateway_allow_all_users/_get_allow_bots) resolve snapshot -> config.extra
-> scope-aware env, replacing every raw os.getenv gate read: on_message
channel gates, _is_allowed_user allow-all flags, slash authorization,
fail-closed diagnostics, missed-message backfill, bot-message gating,
and _component_check_auth (component buttons).
- _apply_yaml_config always seeds gate values into PlatformConfig.extra
(incl. new allowed_roles / allow_all_users keys) and SKIPS the
process-global env writes when loading a profile-scoped config under
multiplex; the legacy first-writer env bridge is preserved verbatim for
single-profile deployments.
- _resolve_allowed_usernames no longer unconditionally rewrites
os.environ[DISCORD_ALLOWED_USERS] — under multiplex the resolved IDs stay
adapter-local (snapshot refresh); single-profile keeps the env rewrite.
- Telegram adapter (mirror of the same class): intake prefilter and
callback-auth fallbacks, _telegram_auth_env_configured, and the
allowed/ignored chats-topics-threads getters now read via the scoped gate
reader; _apply_yaml_config skips authorization env writes for
profile-scoped loads and seeds free_response_chats/ignored_threads extras.
Regression tests (tests/plugins/platforms/test_discord_gate_isolation.py):
two adapter instances with different allow-lists enforce their OWN lists
order-independently across message, slash, and component gates; negative
allow-all case proves profile A's open-access flag cannot authorize profile
B; username-resolution env-clobber; YAML-bridge seeding/skip matrix; and the
Telegram scoped-reader matrix. Sabotage-verified: reverting either the
Discord snapshot accessors or the Telegram scoped reader fails 12/2 tests
respectively.
Credit: builds on the per-adapter accessor direction of PR #72427
(@JonthanaHanh) and the scope-aware-reader approach validated live on v0.19.0
by @yournetworkplug-ctrl for the Telegram mirror; scope corrections from
jackjin1997's and cal88's analysis in the issue thread (allow-all flags,
unguarded username-resolution env write, per-site channel reads).
Fixes#72348
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 chronos cron-fire verifier constructed PyJWKClient without explicit
headers, so its JWKS fetch to the NAS portal hit the same WAF 403 the
dashboard-auth providers already guard against. It reaches the same
portal issuer, so it's the same bug class — mirror the fix here and add
a constructor-contract regression test.
Co-authored-by: James Hodgkinson <james@terminaloutcomes.com>
The Nous PyJWKClient was constructed without explicit headers, while the
self_hosted provider already sends Accept + User-Agent. Without them the
Portal WAF can block the JWKS fetch, so the same failure mode remained for
the Nous dashboard-auth route. Mirror the self_hosted fix and add a
constructor-contract regression test.
An "Estimate" action asks the auto-routed auxiliary model for a rough token
count + complexity band (S/M/L) with a one-line rationale — tokens, not
dollars, since providers don't report cost reliably. POST /estimate (typed
title/body, for the create dialog) and POST /tasks/{id}/estimate (existing
cards) share one core. Desktop renders it inline ("~15k tok · Medium") with a
"makes a model call" disclaimer; SDK exports compactNumber.
Boards gain an optional project_id. When set, the board's default_workdir
mirrors the project's primary repo and every new task inherits the project —
a deterministic worktree + branch per task — unless it names its own. New
GET /projects; board create/patch/list carry project_id + resolved name; the
create dialog defaults its workspace to the board's and allows a per-task
path override. Desktop: "Board settings…" gains a project picker.
Replace OS-scheduler-dependent elapsed-time ceilings with deterministic
concurrency proofs in three tests:
- test_context_refs_concurrent: asyncio.Barrier rendezvous — all 3 URL
fetches must be in flight simultaneously before any returns.
- test_memory_boundary_commit: positive non-blocking witness — the
provider call list must still be empty when the async commit returns.
- test_mem0_v3 slow-prefetch: threading.Event park/release — prefetch
must return while the backend search is still parked.
The tests/tools/test_mcp_tool.py hunk from the original PR is dropped:
main no longer carries the 'elapsed < 2.5' assertion it targeted
(superseded by a delay-relative bound).
Salvaged from #71913.
Combines the Windows-hermeticity cluster (#67512 by @webtecnica, earliest;
#71112 by @Sanjays2402; #67196 by @anatolijlaptev1991-ctrl) into one fix:
- scripts/run_tests.sh: env -i forwarded only HOME, but native Windows
CPython resolves Path.home() from USERPROFILE (or HOMEDRIVE+HOMEPATH),
stdlib paths from LOCALAPPDATA/APPDATA, ssl/sockets need SYSTEMROOT,
tempfile needs TEMP/TMP — the strip broke collection tree-wide on
native Windows (issues #67385, #70813). Location vars (never
credentials) are now forwarded, each only when actually set, so
POSIX runs are byte-for-byte unchanged (probe-verified both ways).
PYTHONUTF8=1 added for legacy-codepage consoles printing the
runner's glyphs.
- tests/plugins/memory/test_hindsight_provider.py: _clean_env patched
HOME only; on Windows Path.home() ignores HOME. Now patches
Path.home directly into tmp_path (from #67196).
Not ported: #71112's guard test — it regex-reads run_tests.sh source,
which the test policy bans (never read source code in tests).
Fixes#67385. Fixes#70813.
Same sibling-mock class as the relay-metrics runtime file — this test
stubs the telemetry gate's config read, which now goes through
read_raw_config_readonly(). Swept the whole test tree for remaining
read_raw_config stubs: all others target consumers that still use the
mutable reader (browser config, url_safety, inventory) and carry no
telemetry keys.
Three GUI Capabilities-tab defects reported on Windows:
1. Browser rows stuck on 'Setup required' after a successful setup run.
Root causes, all in the readiness probe (not the installer):
- _has_agent_browser() never searched the Hermes-managed Node dir
(%LOCALAPPDATA%/hermes/node / $HERMES_HOME/node/bin) where the
Windows install lands, and probed node_modules/.bin/agent-browser
as the extensionless POSIX shim, which fails exec on Windows
(WinError 193) — now resolved via PATHEXT-aware shutil.which
against both rungs, mirroring _find_agent_browser().
- Cloud rows (Nous Subscription Browser Use, Browserbase, Browser
Use, Firecrawl) declared post_setup: agent_browser, whose
readiness gate requires a LOCAL Chromium build the cloud never
uses — switched to the cloud-scoped 'browserbase' hook (CLI-only).
- _agent_browser_installed() could read browser_tool's stale cached
'Chromium missing' result from before the install ran in the
spawned post-setup process — cache now dropped before probing so
the pill flips to Ready right after a successful run.
2. No way to tell which backend is active, and clicking a row to read
its details silently rewrote config. Row click now only
expands/collapses; activation is an explicit 'Use this backend'
button, the active row carries an 'Active' pill, and the expanded
active row says 'This is your active backend'.
3. OpenAI TTS showed one model and one voice. The options were always
defined but rendered through a native <datalist>, which filters by
the field's current value — a field already set to a valid option
suggested only itself. Replaced with a real combobox (Input +
dropdown) that lists every option, and voice suggestions now track
the selected model per the OpenAI TTS docs: tts-1/tts-1-hd = 9
voices, gpt-4o-mini-tts = 13 (adds ballad, verse, marin, cedar).
