+"""Fast-path fixtures shared across tests/agent/.
+
+Many tests in this directory exercise the retry/backoff paths in the
+agent loop. Production code uses ``jittered_backoff(base_delay=5.0)``
+with a ``while time.time() < sleep_end`` loop — a single retry test
+spends 5+ seconds of real wall-clock time on backoff waits.
+
+Mocking ``jittered_backoff`` to return 0.0 collapses the while-loop
+to a no-op (``time.time() < time.time() + 0`` is false immediately),
+which handles the most common case without touching ``time.sleep``.
+
+We deliberately DO NOT mock ``time.sleep`` here — some tests
+(test_interrupt_propagation, test_primary_runtime_restore, etc.) use
+the real ``time.sleep`` for threading coordination or assert that it
+was called with specific values. Tests that want to additionally
+fast-path direct ``time.sleep(N)`` calls in production code should
+monkeypatch ``run_agent.time.sleep`` locally (see
+``test_anthropic_error_handling.py`` for the pattern).

+"""The borrowed ``claude_code`` row is a reference, never a token authority.
+
+``claude_code`` is absent from ``_PERSISTABLE_PROVIDER_SOURCES``, so
+``sanitize_borrowed_credential_payload`` strips ``access_token`` and
+``refresh_token`` before the pool row reaches ``auth.json``: what survives on
+disk is provenance, status and a ``secret_fingerprint``.  ``load_pool()``
+re-hydrates the live pair from ``~/.claude/.credentials.json`` on every load,
+which is what makes the singleton -- not the pool store -- authoritative for
+this source.
+
+Two failure modes follow from forgetting that, and both are covered here:
+
+1. ``_sync_anthropic_entry_from_pool_store()`` re-reads the persisted row
+   during refresh.  For a borrowed source that row has *no* tokens, so it
+   "differs" from the live entry and was adopted as though another process had
+   rotated the pair -- blanking a usable credential and returning before
+   ``_claude_code_credentials_lock()`` and the authoritative re-read were ever
+   entered.
+2. ``_available_entries()`` only refused to lease empty *API-key* rows, so the
+   blanked OAuth entry stayed selectable and would have been sent as an empty
+   bearer.
+
+The existing race/write-through suites build ``CredentialPool`` objects
+directly or back the store with unsanitized in-memory rows, so neither crosses
+the real persistence boundary.  Every test below starts from ``load_pool()``
+reading an actually persisted, actually sanitized row.

+Companion to ``tests/agent/test_credential_pool_anthropic_refresh_race.py``,

+under real concurrency. The thread stress case keeps the suite fast while a
+separate spawn-based case uses independent interpreters, distinct profile
+homes, and one shared Claude Code credentials file. Both exercise the REAL
+cross-process file lock (``_auth_store_lock``) and REAL credential-pool
+persistence under throwaway directories — only the network call to Anthropic
+is faked. The process case also counts refresh POSTs and requires exactly one
+use of the stale single-use token, so a broken lock cannot remain green merely
+because two in-process mocks happened to finish quickly.

+chat_completions and bedrock_converse.  Before this PR, the

+"""Row-addressed ``api_content`` backfill (NousResearch/hermes-agent#102194).
+
+The sidecar is stamped by the turn prologue and normally reaches the DB in the
+same INSERT as the clean content (the crash persist runs after the stamp). When
+another writer materialized the current turn's user row FIRST — in-place
+preflight compaction, or a close/early flush that raced the prologue — that
+insert never happens: the crash persist marker-skips the message and the row
+keeps ``api_content = NULL``, so the next turn replays clean content and the
+request prefix diverges exactly at that message.
+
+The prologue therefore backfills, but only when a row provably exists for THIS
+dict. ``_row_id`` is that proof and that address: both early writers stamp it on
+the live message (``_insert_message_rows`` directly, ``sync_flushed_message_markers``
+after the batch commit). A positional "newest active user row" update cannot be
+substituted for it — a repeated user turn ("ok", "y", "continue") makes the
+previous turn's row compare equal on content, and the backfill would overwrite
+that turn's sidecar with this turn's bytes.

+2. ``_create_with_progress`` retries ONCE with the provider-stated affordable

+"""Regression: _try_anthropic() must fall back to the legacy token resolver
+when the credential pool is present but has no usable entry.
+
+Root cause (observed 2026-07-05): the pooled Anthropic OAuth entry expired and
+its refresh_token was stale, so `_select_pool_entry("anthropic")` returned
+`(True, None)` — pool exists, no selectable entry. The old `_try_anthropic`
+hard-failed on that branch (`return None, None`), even though a perfectly
+valid `ANTHROPIC_TOKEN` / credentials-file token was available. This wedged
+every auxiliary task routed to Anthropic (goal judge → "no auxiliary client
+configured"), while the MAIN session stayed healthy because it resolves the
+env token directly.
+
+openrouter (test_try_openrouter_pool_exhausted_falls_back_to_env) and codex

+"""Tests for auxiliary client routing of the ``azure-foundry`` provider.
+
+Covers the dedicated branch in ``agent.auxiliary_client.resolve_provider_client``
+that delegates to :func:`hermes_cli.runtime_provider._resolve_azure_foundry_runtime`
+instead of falling into the generic ``resolve_api_key_provider_credentials``
+path (which only knows about ``AZURE_FOUNDRY_API_KEY`` and would 401 for
+Entra ID users and miss ``model.base_url`` overrides for api-key users
+with non-standard Foundry-projects endpoints).
+
+Pinned scenarios:
+
+  * ``auth_mode: api_key`` → plain OpenAI client with the static string
+    key for ``chat_completions``.
+  * ``auth_mode: entra_id`` + ``chat_completions`` → plain OpenAI
+    client with a callable ``api_key`` (the bearer-token provider) —
+    confirms the callable survives the auxiliary path end-to-end.
+  * ``auth_mode: entra_id`` + GPT-5.x model → CodexAuxiliaryClient
+    wrapping the OpenAI client (api_mode auto-upgrades to
+    codex_responses).
+  * Anthropic-style + entra_id → rejected at the runtime resolver,
+    so the aux path returns ``(None, None)``.
+  * Failure path when no model is configured returns ``(None, None)``
+    cleanly so the auto chain falls through.

+"""Regression tests for the codex_app_server → Hermes UI event bridge.
+
+Pin the translation of codex JSON-RPC notifications into agent callbacks
+(`tool_progress_callback`, `_fire_stream_delta`, `_fire_reasoning_delta`,
+`_emit_interim_assistant_message`) so Discord/Telegram/TUI continue to
+surface live tool-progress bubbles and interim assistant commentary when
+the active provider runs on `openai_runtime: codex_app_server` (#33200).
+
+Each test drives `make_codex_app_server_event_bridge(agent)` directly with
+fixture notifications that mirror codex 0.130.0's `item/*` shape and
+asserts the right agent callback fired with the right arguments. The
+bridge is deliberately small (~150 lines of pure dict mapping) so the
+tests can stay focused on the wire format ↔ callback contract.

+"""Regression coverage for #32892.
+
+The openai SDK's ``responses.stream()`` / ``responses.parse()`` eagerly
+call ``_make_tools(tools)``, which iterates ``tools`` *without* a None
+guard.  Passing ``tools=None`` therefore raises::
+
+    TypeError: 'NoneType' object is not iterable
+
+…before any HTTP request is issued.  This trips the
+``openai-codex`` / ``gpt-5.5`` combo on ``chatgpt.com/backend-api/codex``
+whenever the user runs Hermes without external tools registered: the
+agent loop catches the TypeError, sees no HTTP status, classifies it as
+non-retryable, and aborts (#32892).
+
+These tests pin the defence:
+:func:`agent.transports.codex.ResponsesApiTransport.build_kwargs` must
+never emit ``tools=None`` — only add the ``tools`` key when there are
+function tools to expose.  When there are no tools, the entire ``tools``
+key (plus ``tool_choice`` and ``parallel_tool_calls`` which are
+meaningless without it) is omitted from the kwargs.
+
+Note: #33042 separately removed the SDK's ``responses.stream()`` helper
+from our own Codex call paths, so the specific iteration crash inside
+``_make_tools`` is also structurally avoided in normal operation.  This
+test class additionally pins the SDK's ``_make_tools(None)`` contract so
+we notice if upstream ever changes it.

+   uninterruptible worker is orphaned behind the poison fence — its late
+   result is discarded and, on the total-ceiling path, the durable lease is
+   retained until it exits so no new attempt overlaps the unchanged session.
+2. A failed/stalled/cancelled attempt records a durable per-session backoff
+   (strategy + failure kind stamped into the state.db cooldown row) that
+   SURVIVES a gateway restart; the next automatic turn skips the same
+   strategy inside the window, and a successful compression clears it.
+3. Late results from a superseded attempt are discarded, never committed
+   over newer state (generation counter), and a transiently-blocked no-op is
+   reported as a soft defer — never compression_exhausted (false auto-reset).

+"""Regression: prevent transcript fork when two paths compress the same session_id.
+
+Damien's incident (Discord, 2026-05-28): a long Hermes session in a Discord
+gateway hit the compression threshold at the end of a turn.  The parent agent
+finished delivering the response and ``conversation_loop.py`` fired
+``_spawn_background_review(...)`` — which builds a forked ``AIAgent`` that
+inherits ``agent.session_id`` (see ``agent/background_review.py``::
+``review_agent.session_id = agent.session_id``).  Roughly two seconds later
+a synthetic ``Background process proc_… completed`` event arrived and
+started a fresh turn on the same parent ``session_id`` (still cached in the
+gateway's ``SessionEntry``).  Both paths hit preflight compression on the
+same parent transcript and called ``_compress_context`` concurrently.  Each
+ended the parent and created its own CHILD session in ``state.db``, both
+parented to the same old id.  The gateway's ``SessionEntry`` only caught one
+rotation; the other child became an orphan that silently accumulated writes.
+
+Repro shape on Damien's machine:
+
+  parent 20260527_234659_e65f0e  ended_at=set  end_reason='compression'
+  child  20260528_113619_fc80e1  parent=20260527_234659_e65f0e  (in SessionEntry)
+  child  <orphan>                parent=20260527_234659_e65f0e  (silent writes)
+
+This regression simulates the two concurrent ``compress_context`` calls
+against a shared ``state.db`` and asserts that the per-session compression
+lock added in this PR prevents the orphan child.  Without the lock the
+fixture deterministically produces 2 children; with the lock, exactly 1.

+"""Regression for #23975: context compression must survive a mid-flight
+gateway interrupt.
+
+While the compression summary LLM call is in flight, an incoming gateway
+message sets the thread interrupt flag. The Codex Responses aux stream polls
+that flag and used to raise InterruptedError unconditionally — aborting the
+summary, which then fell back to a degraded static "summary unavailable"
+marker (losing the real handoff). Compression now runs its summary call
+under aux_interrupt_protection(), so the interrupt poll is masked for the
+compression task only (timeouts and other aux tasks stay interruptible).

+"""Regression guard: interpreter-shutdown errors must abort the conversation

+When the Python interpreter begins its teardown sequence, every executor-backed
+operation (API calls, tool dispatch, memory sync) raises::

+    RuntimeError: cannot schedule new futures after interpreter shutdown
+
+Before the fix, the outer ``except Exception`` handler in

+Since ``api_call_count`` was nowhere near ``agent.max_iterations - 1``, the
+loop continued — each iteration hit the same dead executor and failed
+identically, producing a cascade of ``❌ Error during OpenAI-compatible API
+call #N`` messages (#93217).
+
+The fix adds an early check in the outer except handler: if

+"""Regression guardrail: sequential _create_openai_client calls must not
+share a closed transport across invocations.
+
+This is the behavioral twin of test_create_openai_client_kwargs_isolation.py.
+That test pins "don't mutate input kwargs" at the syntactic level — it catches
+#10933 specifically because the bug mutated ``client_kwargs`` in place. This
+test pins the user-visible invariant at the behavioral level: no matter HOW a
+future keepalive / transport reimplementation plumbs sockets in, the Nth call
+to ``_create_openai_client`` must not hand back a client wrapping a
+now-closed httpx transport from an earlier call.
+
+AlexKucera's Discord report (2026-04-16): after ``hermes update`` pulled
+#10933, the first chat on a session worked, every subsequent chat failed
+with ``APIConnectionError('Connection error.')`` whose cause was
+``RuntimeError: Cannot send a request, as the client has been closed``.
+That is the exact scenario this test reproduces at object level without a
+network, so it runs in CI on every PR.

+"""Custom-provider TLS settings must reach the /models and pricing probes.
+
+Regression coverage for provider-scoped ``ssl_ca_cert`` / ``ssl_verify`` being
+ignored by the discovery/pricing probes. Two probe families share the root
+cause and are covered here:
+
+* ``requests``-based endpoint metadata / pricing probe
+  (``agent.model_metadata.fetch_endpoint_model_metadata`` via
+  ``_resolve_requests_verify``).
+* ``urllib``-based ``/models`` catalog discovery probe
+  (``hermes_cli.models.probe_api_models`` via ``_custom_provider_ssl_context``).
+
+Both previously resolved TLS from process-wide env vars only, so a custom
+endpoint whose chain verifies against the provider's configured bundle (but not
+``SSL_CERT_FILE``) logged a spurious CERTIFICATE_VERIFY_FAILED on every probe
+even though the chat client succeeded.
+
+No network I/O: real CA-bundle stand-in files via ``tmp_path`` plus a patched
+provider list and a patched request seam.

+"""Host-declared conversation scope on the affinity-key path (issue #96811).
+
+A host that mints one physical ``session_id`` per RESPONSE re-keys every
+conversation-affinity hint Hermes sends — ``prompt_cache_key`` on both
+OpenAI-wire transports, the OpenRouter/Nous sticky ``session_id``, and xAI's
+``x-grok-conv-id`` — so the conversation never lands back on the routing
+bucket it warmed. Hermes cannot infer the logical conversation from the id's
+syntax (#79017's failure class), but it does not have to: the host declares
+it through ``gateway_session_key`` (the ``X-Hermes-Session-Key`` /
+``build_session_key`` per-chat key).
+
+These tests pin the declaration contract and the two boundaries it must not
+cross: explicit fork children (``/branch``, delegate, tool) and
+background-review forks, which share the parent's chat key but are separate
+conversations under #79161.

+"""Regression guard: preserve thinking blocks on DeepSeek's /anthropic endpoint.
+
+DeepSeek's ``api.deepseek.com/anthropic`` route speaks the Anthropic Messages
+protocol but, when thinking mode is enabled, requires ``thinking`` blocks from
+prior assistant turns to round-trip on subsequent requests.  The generic
+third-party path strips them (signatures are Anthropic-proprietary and other
+proxies cannot validate them), so without a DeepSeek-specific carve-out the
+next tool-call turn fails with HTTP 400::
+
+    The content[].thinking in the thinking mode must be passed back to the
+    API.
+
+DeepSeek's compatibility matrix lists ``thinking`` as supported but
+``redacted_thinking`` and ``cache_control`` on thinking blocks as not
+supported.  Handling is the same as Kimi's ``/coding`` endpoint: strip
+Anthropic-signed blocks (DeepSeek can't validate them) but preserve unsigned
+blocks that Hermes synthesises from ``reasoning_content``.

+  2. The next attempt hits HTTP 429.
+  3. Before this fix, an eager-fallback attempt that lost its race with
+     a concurrent session mutating the on-disk credential pool could
+     leave ``_fallback_index`` advanced past the chain length without
+     setting ``_fallback_activated`` to True.  The subsequent 429s then
+     short-circuited the eager-fallback gate (``_fallback_index >=
+     len(_fallback_chain)``), so the retry budget burned on the primary
+     model with no fallback ever attempted.
+  4. The fix resets ``_fallback_index`` / ``_fallback_activated`` /
+     ``TurnRetryState.has_retried_429`` after transport recovery so the post-recovery
+     429 always gets a fresh fallback-chain attempt.

+"""Regression tests for #24996 — fallback-switch storm on host memory.
+
+When every provider in the fallback chain fails non-retryably back-to-back
+(e.g. HTTP 400/402/429 across distinct providers), the within-turn walk is
+bounded (``_fallback_index`` advances monotonically and the loop aborts when
+the chain exhausts).  The damaging mode is *cross-turn*: ``restore_primary_
+runtime`` resets ``_fallback_index = 0`` every turn, so a client that
+re-submits immediately replays the entire chain — re-marshaling the full
+(potentially 80k-token) context once per provider every turn — with no
+throttle on the non-rate-limit path.
+
+The fix arms a short cooldown via the existing ``_rate_limited_until`` gate
+when the chain exhausts on a non-rate-limit failure, so the next turn's
+restore stays gated (and does NOT reset the index) until the cooldown clears.
+Rate-limit / billing failures keep their own 60s cooldown and are unaffected.

+"""Regression test for #98450: in-place batch compaction commit must stamp
+_DB_PERSISTED_MARKER on the committed dicts.
+
+``compress()`` returns marker-swept COPIES (``_strip_persistence_markers``,
+#57491 — the sweep protects the ROTATION flush to a child session). The
+in-place branch commits those copies durably via
+``SessionDB.archive_and_compact()`` and hands the SAME dict instances back
+as the live message list. Without a post-commit stamp, the next
+``_persist_session`` → ``_flush_messages_to_session_db_unlocked`` walk sees
+every compacted row as unpersisted and re-INSERTs the whole post-compaction
+transcript — the live set doubles on every compaction (production:
+~58K → ~512K tokens in two hours).
+
+The healthy sibling ``ContextCompressor._sync_micro_compact_to_db`` already
+stamps after its ``archive_and_compact`` call; both now share
+``stamp_db_persisted_markers``.

+Root cause: ``get_messages_as_conversation`` / ``get_resume_conversations``
+returned plain dicts WITHOUT ``_DB_PERSISTED_MARKER``. Any flush that received
+that loaded history without a matching ``conversation_history=`` identity
+boundary (compression durable-snapshot adoption, incremental tool-call
+persists, rotation preflight on cold resume) treated every loaded row as new
+and re-appended the ENTIRE transcript. Compression cycles then doubled the
+copies: the incident session grew 998 → 1995 → 3990 → 7981 rows across three
+aborted rotations (15,962 active rows / 472 distinct contents).
+
+Fix: rows are stamped durable at materialization time in
+``SessionDB._rows_to_conversation`` — a dict built FROM a durable row is
+persisted by construction, no matter which caller loads it or how it is later
+handed to a flush.

+"""Regression guard for #15218 — external memory sync must skip interrupted turns.
+
+Before this fix, ``run_conversation`` called
+``memory_manager.sync_all(original_user_message, final_response)`` at the
+end of every turn where both args were present.  That gate didn't check
+the ``interrupted`` flag, so an external memory backend received partial
+assistant output, aborted tool chains, or mid-stream resets as durable
+conversational truth.  Downstream recall then treated that not-yet-real
+state as if the user had seen it complete.
+
+The fix is ``AIAgent._sync_external_memory_for_turn`` — a small helper
+that replaces the inline block and returns early when ``interrupted``
+is True (regardless of whether ``final_response`` and
+``original_user_message`` happen to be populated).
+
+These tests exercise the helper directly on a bare ``AIAgent`` built
+via ``__new__`` so the full ``run_conversation`` machinery isn't needed
+— the method is pure logic and three state arguments.

+Micro-compaction amortizes the cost of context compression: instead of one
+long pause when the window fills, each turn folds the single oldest
+un-absorbed exchange into a rolling summary.
+
+The invariants that matter:
+
+* one call absorbs exactly one exchange (assistant + its tool results), so
+  the per-turn cost stays bounded;
+* the absorbed span is replaced by a summary marker carrying the usual
+  ``_compressed_summary`` metadata, so resume/handoff treat it like a batch
+  summary;
+* the cursor advances, so successive calls walk forward rather than
+  re-summarising the same exchange;
+* protected head and tail messages are never touched;
+* an exchange the summarizer cannot handle is retried a bounded number of

+"""Tests for MoA trace aggregator-output capture across streaming modes.

+The MoA full-turn trace (opt-in ``moa.save_traces``) must record the
+aggregator's acting output whether the aggregator ran non-streaming (inline
+capture at call time) or streaming (captured after the fact from the caller's
+resolved assistant text). Before the streamed-capture fix, a streamed
+aggregator left ``output: null`` in the trace and only pointed at state.db,
+so an offline audit of a benchmark run (which drives the streaming display
+path via ``hermes chat --query``) couldn't see what the aggregator actually
+produced without joining to the session DB by hand.

+"""Regression guard: a genuine Nous 429 must re-enter the retry loop so the

+
+Bug (found in the #44061 audit): the genuine-rate-limit branch in
+``agent/conversation_loop.py`` set ``retry_count = max_retries`` then
+``continue``-d, intending the top-of-loop guard to "handle fallback or bail
+cleanly".  But the loop condition is ``while retry_count < max_retries`` —
+setting retry_count equal to max_retries makes the condition False
+immediately, so the guard NEVER runs.  No fallback activation, no clean
+rate-limit message: the turn dies with the generic retry-exhaustion error.
+
+The fix sets ``retry_count = max(0, max_retries - 1)`` so the loop body runs
+exactly once more: the guard sees the breaker state recorded by
+``record_nous_rate_limit()`` moments earlier and either activates a fallback
+provider (resetting retry_count) or returns the explicit rate-limit failure.

+"""A successful compaction hands allocator pages back to the OS.

+trim_memory lifecycle covers the gateway/TUI housekeeping loops but not the

+"""Regression: multiplex gateway profile scoping + full-prompt wiring.

+Two scenarios for _agent_home's resolution order (#86313 post-merge findings):
+
+1. MULTIPLEX INVERSION (@kshitijk4poor): the messaging gateway hands every
+   agent the shared launch-home state.db but binds the profile home per turn
+   via the HERMES_HOME ContextVar (copy_context into the worker). A bound
+   override must WIN over the db-derived launch home, else the shared-db
+   fallback stomps the correct profile deterministically.
+
+2. BARE THREAD (the original #86313 fix): no override bound — the db-derived
+   home must still win over ambient env resolution.
+
+Plus the full-prompt wiring test (@helix4u): build_system_prompt_parts on a
+bare thread with the bot's session DB must produce a prompt whose identity
+(SOUL.md), skills block, and profile line ALL belong to the bot — reverting
+any single call-site wire breaks this test.

+"""Tests for the rotation-stable prompt-cache scope (issue #79017).
+
+Legacy ``compression.in_place: false`` compaction rotates the physical
+session_id mid-conversation. The prompt_cache_key scope (#79161) was derived
+from that physical id, so every rotation went cache-cold. The fix resolves
+the compression-lineage ROOT once per turn and threads it to the key
+derivation sites, while preserving #79161's isolation semantics for /new,
+/branch, delegate subagents, tool children, and unrelated sessions.

+"""Bounded native scope operations in the Relay session coordinator.
+
+The NeMo Relay native binding's ``scope.pop``/``scope.push`` are synchronous
+and unbounded ("returns after the scope is closed successfully").  When the
+native pipeline cannot make progress — proven live 2026-08-10 in the
+delegation topology, where child sessions register scopes under the parent's
+handle on a shared runtime — the coordinator's turn/session finalization
+blocks forever inside ``run_conversation``.  Children finish their turns but
+never return; delegation batches die on the stall watchdog.
+
+Contract under test: observability must never block the product.  Scope
+lifecycle operations that gate turn/session completion are bounded; on
+breach the existing per-site exception handling degrades gracefully (warn,
+retain diagnostics, continue) and the agent lives.  A lost span is always
+the right trade against a dead agent.
+
+These tests use a fake relay whose ``pop`` blocks on a never-set Event —
+the minimal stand-in for a wedged native pipeline.  They assert the
+END-TO-END contract (the coordinator method RETURNS) rather than any
+helper's internal shape.

+"""Regression coverage: the compaction summary role must alternate against
+TEMPLATE-VISIBLE neighbours, not literal list neighbours.
+
+Mistral-family chat templates (Devstral, Mistral Small 3.x, Magistral)
+enforce user/assistant alternation at render time but exempt the tool flow
+from the check: ``tool`` results and assistant messages carrying
+``tool_calls`` are skipped. The summary-role selection previously keyed off
+the LITERAL last head message (``compressed[-1]``), producing this captured
+failure (Hermes Desktop v0.19.0 against llama.cpp-served Devstral):
+
+    [0] system
+    [1] user            <- original first user turn, protected
+    [2] assistant       (tool_calls, exempt)
+    [3] tool            (exempt)
+    [4] user            <- COMPACTION SUMMARY, pinned to "user" because the
+                           literal previous role was "tool"
+    [5..] assistant(tool_calls)/tool pairs
+
+The template counts only [1] and [4]: user -> user, and the backend rejects
+the ENTIRE request with a Jinja alternation error (HTTP 500):
+
+    "After the optional system message, conversation roles must alternate
+     user and assistant roles except for tool calls and results"
+
+Because the summary persists in the stored conversation, every retry
+replays the same poisoned history: the session is permanently broken, on
+EVERY compaction, overflow or not.
+
+These tests pin the fix: neighbour roles for summary-role selection are
+computed by ``_template_visible_role`` (skipping the exempt tool flow), and
+the assembled output always satisfies the Mistral alternation check. The
+existing #52160 / #58753 forced-user guards must keep winning: their forced
+shapes (summary-user followed only by exempt messages) are alternation-safe.

+"""Tests for ``agent.conversation_loop._restore_or_build_system_prompt``.
+
+Validates the gateway DB-roundtrip path that keeps the system prompt
+byte-stable across turns (fresh AIAgent → must restore from session DB
+instead of rebuilding).  Covers:
+
+  * Successful restore from a stored prompt (present row).
+  * Legitimate first-turn build (no history).
+  * Silent-failure recovery paths:
+      - DB read raises → WARNING + fresh build
+      - Row has system_prompt=NULL → WARNING + fresh build
+      - Row has system_prompt="" → WARNING + fresh build
+      - DB write fails → WARNING (subsequent turns will miss cache)

+"""Behavior contracts for incremental tool-call persistence (#49045).
+
+A destructive or process-terminating tool that runs during tool execution
+must not lose the just-executed assistant(tool_calls) block or the tool
+results that were produced before it fired.  These tests pin the contract:
+
+    1. run_conversation flushes the assistant tool-call turn to the session
+       DB BEFORE handing control to _execute_tool_calls (so a tool that
+       restarts/kills the process never orphans the tool-call block).
+    2. The SEQUENTIAL tool path flushes each tool result to the session DB
+       immediately after appending it — BEFORE the next tool dispatches.
+    3. The CONCURRENT tool path flushes each tool result in append order.
+
+These exercise the REAL production dispatch surfaces:
+
+    * sequential -> ``model_tools.handle_function_call`` (tool_executor ~1256/1298)
+    * concurrent -> ``agent._invoke_tool`` (tool_executor ~539)
+
+Mocking the genuine dispatch surface keeps the tests deterministic (no real
+``web_search`` / network) AND mutation-survivable: the ordering assertions
+read snapshots captured at flush time, so removing any production flush call
+makes the corresponding assertion fail.

+"""Tests for the end-of-turn completion explainer (#34452).
+
+When a turn ends abnormally after tools (empty content after retries, a
+partial/truncated stream, exhausted retries, or an iteration/budget limit)
+the user should get a single user-visible explanation of why the reply
+stopped instead of a blank or fragmentary response box.  Normal short
+replies (e.g. ``Done.``) must stay quiet.
+
+These tests exercise:
+  1. ``_format_turn_completion_explanation`` — the pure reason→message map.
+  2. ``_turn_completion_explainer_enabled`` — the env/config seam.
+  3. An end-to-end ``run_conversation`` turn that exhausts empty-response
+     retries and verifies the explanation reaches ``final_response``.
+
+All assertions work under the mocked OpenAI SDK used elsewhere in this
+suite (we patch ``agent.process_bootstrap.OpenAI`` and drive ``agent.client``), so they
+pass identically in CI and locally.

+``_proactive_prune_rearm_tokens`` on its successful tail — correct for a
+COMMITTED compaction (the boundary already broke the prompt-cache prefix, so
+the throttle restarts from the new baseline). But ``compress_context``'s
+anti-growth guard can then REFUSE the result and keep the original
+transcript, whose cached prefix is intact. Before the fix, that refusal
+returned with the in-memory runway still at 0 while the durable
+``model_config`` copy kept the old value:
+
+- the very next eligible iteration's proactive prune fired without the
+  regrowth interval #79640 introduced — an immediate, unthrottled
+  cache-breaking rewrite of history that was still byte-identical to what
+  the provider had cached, and
+- memory and disk disagreed until the next restart silently re-armed the
+  throttle from the stale durable row.
+
+The refusal branch now restores the runway from the attempt snapshot, the
+same targeted restore the rotation-failure rollback already performed.

+
+Status data comes from two sources:

+     claimed by any status become synthesized ❌ Error items.
+
+Layout rules tested here:
+  - group headers: ## ❌ Job failures, ## ⚠️ Action required, ## ⚠️ Warnings
+  - each item is a ### section under its group header
+  - errors + action_required always visible
+  - warnings shown only when present
+  - info above the fold; debug in a collapsible <details> block
+  - sections separated by ---
+  - how_to_fix rendered at bottom of action_required items

+
+Mechanism (traced on 85a55e2b30-era main, re-verified through 03b87d666d):
+
+* Background DMs deliver via a separate ``hermes -p <profile> chat``
+  subprocess (``tools/bot_relay.py::local_delivery_command``) that writes the
+  turn straight to the session DB. No gateway stream event reaches the desktop.
+* The gateway broadcasts ``sessions.changed`` on state.db mtime movement, and
+  the desktop's tick handler calls ``requestActiveTranscriptRefresh(true)`` —
+  but that refresh covers ONLY the MAIN pane's selection
+  (``activeStoredSessionId = selectedStoredSessionId``, wiring.tsx).
+* Bot canonical chats open as workspace tiles (``workspaceMode: 'bots'``,
+  never the main selection), AND ``resolveActiveTranscriptSession()`` bails
+  when the session is absent from ``$sessions``/``$messagingSessions`` — which
+  bot chats always are (they carry the core ``hidden`` flag,
+  plugin.js "Bot Mode sessions are ALWAYS hidden").
+
+Double exclusion ⇒ the sessions.changed refresh silently no-ops for exactly
+the conversation the user is staring at.
+
+Fix contract (slice 1): the sessions.changed tick must also reconcile the
+transcripts of VISIBLE workspace tiles — signature-gated like the main pane,
+keyed off each tile's stored↔runtime id pair — without touching messaging
+polls, roster cadence, or the main-pane path.

+  rebuilt runtime emits its ``session.info`` (and all later stream events)
+  under a NEW explicit ``session_id``; the old id is dead.
+* The pane's identity is the pair ``(activeSessionIdRef, selectedStoredSessionIdRef)``.
+  After the rebuild, incoming events carry an explicit sid that no longer
+  equals ``activeSessionIdRef.current``, so ``isActiveEvent`` is False for every
+  subsequent event of the SAME conversation — view-scoped side effects stop,
+  and the pane keeps listening on a dead runtime until a full resume.
+* Existing machinery covers compression rotation only:
+  ``ensureSessionState`` fires the stored-id rotation signal when the SAME
+  runtime's stored id rotates — but a model-switch rebuild produces a NEW
+  runtime with a NEW stored id, which is invisible to that path.
+
+Fix contract: when a ``session.info`` event's lineage
+(``sessionMatchesStoredId`` on ``stored_session_id``) matches the currently
+selected conversation but its runtime id differs from the active one, re-bind
+the pane: adopt the new runtime id as the active session id (keeping the same
+durable selection), so live events keep flowing to the view without a resume.
+Guarded to only fire when the old runtime is dead (no busy/streaming state) so
+an overlapping turn is never hijacked mid-flight.
+
+Together with #94255 (slice 1), this closes #93942.

+"""Per-session exclusivity in the active-session registry.
+
+The property under test is a correctness one, and it is separate from capacity:
+AT MOST ONE LIVE OWNER MAY RUN A GIVEN STORED SESSION, whether or not an
+operator configured ``max_concurrent_sessions``.
+
+It matters because a second owner does not merely duplicate work. It loads its
+own snapshot of the transcript, reasons from a history that does not include the
+first owner's in-flight turn, and then appends to the same stored session -- so
+the conversation ends up containing two replies that never saw each other. That
+was observed in practice before this fence existed: two gateway processes
+resumed one stored session, neither was refused, and both wrote to it.
+
+The old behaviour is worth stating precisely, because it looked deliberate: with
+no cap configured, ``try_acquire_active_session`` returned a disabled no-op lease
+and never touched the registry at all. Capacity being unconfigured was silently
+treated as "concurrent writers to one session are fine", which it never is.

+"""Regression coverage for issue #32243.
+
+OAuth Pro/Max credentials must always reach Anthropic via the native
+``/v1/messages`` endpoint, never the OpenAI-compat ``/chat/completions``
+shim — the latter bills against a separate "extra usage" pool that
+Pro/Max subscriptions don't fund, so any request that lands on it 400s
+with "You're out of extra usage" the moment the gateway starts.
+
+The root cause was an inconsistency between two URL→api_mode helpers:
+
+* ``hermes_cli.providers.determine_api_mode`` correctly mapped
+  ``api.anthropic.com`` to ``anthropic_messages``.
+* ``hermes_cli.runtime_provider._detect_api_mode_for_url`` did NOT, so
+  every code path that fell back to URL-only detection (named custom
+  providers, direct-alias resolution, the api-key fallback inside
+  ``resolve_runtime_provider``) returned ``None`` for that host and
+  defaulted to ``chat_completions``.
+
+Exhaustive host-shape coverage for the helper itself lives in
+``test_detect_api_mode_for_url.py::TestDirectAnthropicHost``.  The
+tests below pin the **integration contract**: every runtime branch
+that resolves an Anthropic endpoint must return
+``api_mode == "anthropic_messages"``, so a future refactor of any
+single branch cannot silently revert #32243.

+"""Legacy ``api_mode`` spellings must keep selecting the transport they named.
+
+Regression coverage for the silent api_mode vocabulary break: earlier
+releases accepted ``api_mode: openai`` on custom provider entries. The
+canonical set consumed by ``agent_init`` is now {chat_completions,
+codex_responses, anthropic_messages, bedrock_converse, codex_app_server},
+and an unrecognized value was silently ignored at BOTH consumption sites:
+
+* ``hermes_cli.config._normalize_custom_provider_entry`` passed the raw
+  string through, so ``agent_init``'s accepted-set check dropped it and
+  fell through to hostname detection.
+* ``hermes_cli.runtime_provider._parse_api_mode`` returned None, with the
+  same fall-through.
+
+For a host with a detection rule (e.g. api.router.com -> codex_responses)
+the provider silently switched transports after an update and broke:
+observed live as every reasoning-bearing request to a relay's untested
+/v1/responses endpoint failing while chat_completions worked. See the
+#66543 discussion.
+
+The fix canonicalizes known legacy/alias spellings through one shared map
+(``_canonical_api_mode``) at both sites. Unknown values still pass through
+unchanged (normalizer) / return None (runtime gate) so existing invalid
+config behavior is untouched.

+"""Regression tests for the test-suite audio-playback guard.
+
+The incident: a plain test run spoke the words "partial answer complete" out
+of a developer's speakers. That string is a fake ``final_response`` from
+``tests/tui_gateway/test_tui_gateway_server.py``. The route was entirely in-process — no
+leaked shell variable, so ``scripts/run_tests.sh``'s ``env -i`` was no help:
+
+  1. A test drives the ``voice.toggle`` RPC with ``action="tts"``. The
+     handler flips the flag by writing the real process environment:
+     ``os.environ["HERMES_VOICE_TTS"] = "1"``.
+  2. The flag outlives that test (``monkeypatch.delenv`` on an *absent* key
+     records no undo entry), so every later test in the process sees it.
+  3. Any later test that drives a turn to completion hits the TTS dispatch in
+     ``prompt.submit``, which calls ``hermes_cli.voice.speak_text`` on a
+     daemon thread with the turn's final response text.
+  4. ``speak_text`` needs no API key to be audible — ``tools/tts_tool.py``
+     defaults to the keyless ``edge`` provider.
+
+Two independent defences in ``tests/conftest.py``, one test each below:
+
+  * ``_HERMES_BEHAVIORAL_VARS`` now blanks ``HERMES_VOICE`` /
+    ``HERMES_VOICE_TTS`` at every test setup, so step 2 cannot cross a test
+    boundary.
+  * ``_audio_playback_guard`` stubs ``speak_text`` outright, so step 3 stays
+    silent even *within* the test that set the flag itself.
+
+The second is the load-bearing one: env blanking alone cannot stop code under
+test from re-setting the variable mid-test.

+"""Regression tests for #93593: a malformed provider key in .env must not
+silently shadow a valid credential-pool key.
+
+Before the fix, ``_resolve_api_key_provider_secret`` returned the FIRST env
+value that passed ``has_usable_secret`` (length + placeholder check only), so
+an obviously malformed OPENROUTER_API_KEY (e.g. a truncated paste or another
+provider's key) in ~/.hermes/.env won over a valid pool entry and produced
+opaque ``401 Missing Authentication header`` errors.
+
+The fix:
+- providers with a declared key prefix (KNOWN_PROVIDER_KEY_PREFIXES) skip
+  env values that don't match, with a WARNING naming the env var, and fall
+  through to the next env var / credential pool;
+- the credential-pool fallback iterates entries instead of only peek(), so a
+  malformed pool entry doesn't block a valid one either;
+- providers WITHOUT a declared prefix are fail-open (unchanged behavior);
+- a VALID env key still wins over the pool (precedence unchanged).

+"""Regression test for a Windows-only PermissionError under lock contention.
+
+``_file_lock()`` (backing ``_auth_store_lock()``) ensures its lock file has
+at least 1 byte of content before opening it for ``msvcrt.locking()`` (which
+requires a non-empty file). That "ensure content" write was unguarded: under
+real concurrency, one thread/process's ``msvcrt.locking()`` byte-range lock
+can already be held on the file at the exact moment another thread runs the
+same ensure-content check, and the write collides and raises
+``PermissionError`` -- uncaught, since it happens before the retry loop the
+rest of the function uses for exactly this kind of contention.
+
+This was found by a stress test for the Anthropic OAuth credential-pool fix
+(``tests/agent/test_anthropic_oauth_stress.py``), which reliably reproduces
+it (16/20 concurrent refreshes hit PermissionError pre-fix, deterministically
+across repeated runs) because the surrounding CredentialPool work widens the
+race window enough for real OS-level thread interleaving to land on it. That
+test is the authoritative regression guard for the exact failure mode. This
+file is deliberately a minimal, isolated stress test against
+``_auth_store_lock()`` directly -- best-effort coverage that does not always
+land on the same narrow window in isolation, but exercises the SAME shared
+primitive Codex/xAI/Nous already depend on for their single-use-refresh-token
+protection, so this bug was never Anthropic-specific.

+Background
+==========
+The three writers below used to create a temp file via ``Path.write_text`` /
+``Path.open('w')`` and only ``chmod``'d it to ``0o600`` afterward. Between
+create and chmod the file existed at the process umask (typically ``0o644``),
+briefly exposing OAuth tokens to other local users on multi-user hosts. The
+writers now go through ``utils.atomic_json_write(mode=0o600)`` whose mkstemp temp
+file is ``O_EXCL`` at 0600 on creation (the cross-writer invariant lives in
+``tests/agent/test_private_credential_writers.py``).
+
+These tests stay green only while the token file and its parent directory
+end up at ``0o600`` / ``0o700`` after every write. POSIX-only — the mode-bit
+enforcement does not exist on Windows.

+"""Tests for Azure Foundry Entra ID runtime resolution.

+
+  * ``_resolve_azure_foundry_runtime`` returns a callable ``api_key`` for
+    ``model.auth_mode = entra_id`` (OpenAI-style only).
+  * Anthropic-style endpoints with ``auth_mode = entra_id`` return the same
+    callable runtime credential as OpenAI-style endpoints.
+  * The legacy ``api_key`` path is unchanged when ``auth_mode`` is absent
+    or set to ``api_key``.
+  * Explicit ``--api-key`` overrides at runtime still work in entra mode
+    (escape hatch for one-off testing).
+  * ``model.entra.scope`` propagates to the token-provider config; Azure
+    identity selection stays in standard AZURE_* env vars.
+  * ``_get_azure_foundry_auth_status`` is structural — never mints a
+    token (verified by checking the credential cache untouched).
+  * ``has_usable_secret`` for ``AZURE_FOUNDRY_API_KEY`` is irrelevant
+    when ``auth_mode == entra_id``.

+"""``bounded_probe_run`` — deadlock-safe capture for fail-open probes (#87134).
+
+On Windows, ``subprocess.run(..., capture_output=True, timeout=N)`` can hang
+FOREVER after its timeout fires: run()'s cleanup kills the direct child and
+then joins the pipe reader threads with an unbounded ``communicate()``.  A
+descendant (``conhost.exe`` under wmic/powershell, ``git.exe`` under a
+launcher shim) holding duplicated pipe handles keeps the pipes from EOF and
+the join never returns.  ``hermes update`` wedged exactly there inside
+``_scan_gateway_pids`` on machines where the full ``Win32_Process`` scan
+exceeds its budget.
+
+``bounded_probe_run`` is the shared, generalized form of the fix that
+``bounded_git_probe`` already proved for git probes (#68609 / #66037):
+explicit ``communicate(timeout)``, tree-kill on failure, bounded 1s drain,
+then abandon.
+
+These tests use REAL subprocesses (no mocks) for the semantics: a mock cannot
+reproduce pipe-handle inheritance or timeout behavior.  The POSIX-only
+descendant-survival cases live in ``test_git_probe_tree_kill.py`` and now
+exercise the same code path through the ``bounded_git_probe`` delegation.

+endpoints the same ``provider_models_cache.json`` TTL cache first-class
+providers already get via ``cached_provider_model_ids()``.
+
+These pin the cache contract directly (hit / stale / rotation / refresh /
+fallback), separate from ``test_model_switch_custom_providers.py``'s

+"""Tests for `chat -c <title>` failing loudly (stderr) and `--create-if-missing`.
+
+Regression for #86794: a background/quiet `hermes chat -c "<title>" -q "..."`
+against a not-yet-existing titled session silently no-oped — the error message
+was written to stdout (which quiet/programmatic callers treat as the "final
+response" channel) instead of stderr, and there was no way to create the
+titled session from the same invocation.
+
+Two behaviors are fixed here:
+
+1. **fail loudly on stderr** — when no session matches `-c <title>`, the error
+   goes to stderr (exit 1), so programmatic callers always see it.
+2. **--create-if-missing** — same invocation with the flag creates a fresh
+   session carrying the title and proceeds, giving plugins/scripts a
+   deterministic "send to this named thread, making it if needed" primitive.

+(094aa85c37) moved agent construction into ``CLIAgentSetupMixin``.

+"""Regression tests for the CLI interrupt-acknowledgement race.
+
+Symptom (user report, July 2026): interrupting an active turn is
+unreliable — the interrupt message is sometimes "vacuumed into the void".
+
+Root cause: ``HermesCLI.chat()`` fires ``agent.interrupt(msg)`` from its
+monitor loop, but only re-queued the message when the turn RESULT carried
+``interrupted=True``. Two races defeat that:
+
+  1. The agent thread passes its last ``_interrupt_requested`` check (or
+     finishes entirely) just before the interrupt lands — the turn
+     completes "normally", ``finalize_turn()`` never acknowledges the
+     interrupt, and the user's message was silently dropped.
+  2. Worse, when the interrupt lands *after* ``finalize_turn()``'s
+     ``clear_interrupt()``, the stale ``_interrupt_requested`` flag
+     survives on the agent and instantly aborts the NEXT turn at its
+     first loop check.
+
+The fix: when ``chat()`` consumed an ``interrupt_msg`` but the result
+doesn't acknowledge the interrupt, re-queue the message as the next turn
+and clear the stale agent flag (only when the agent thread has exited).

+"""Regression tests for the CLI ``/yolo`` in-chat toggle.
+
+Pre-fix bug (issue #33925): ``cli.HermesCLI._toggle_yolo`` mutated only
+``os.environ["HERMES_YOLO_MODE"]``. That env var is captured once at
+module-import time into ``tools.approval._YOLO_MODE_FROZEN`` (security
+hardening: stops prompt-injected skills from flipping the bypass mid-run),
+so the post-startup toggle was a silent no-op. ``/yolo`` advertised "YOLO ON"
+in the status bar while every dangerous command still hit the approval
+prompt. Only ``hermes --yolo`` (process-start env), ``HERMES_YOLO_MODE=1``,
+and ``hermes config set approvals.mode off`` actually bypassed.
+
+The fix routes the CLI toggle through ``enable_session_yolo`` /
+``disable_session_yolo`` (matching the gateway and TUI ``/yolo`` paths) and
+binds ``self.session_id`` as the active approval session key around each
+``run_conversation`` call so ``is_current_session_yolo_enabled()`` resolves
+against the same key the toggle writes under.
+
+We test ``_toggle_yolo`` and ``_is_session_yolo_active`` as unbound methods
+against a minimal stand-in object that exposes only the attribute they
+read (``session_id``). This avoids the heavy ``HermesCLI`` construction
+path used in ``test_cli_init.py``, which is incompatible with this test
+file's path layout — ``HermesCLI.__init__`` imports a lot of optional
+state we don't need here.

+"""Type-ahead queue-drain proof for /compress (issue #61042, PR #68284).
+
+PR #68284 made the classic prompt_toolkit CLI keep the composer editable
+while ``/compress`` runs (``_busy_command(..., blocks_input=False)``), with
+the docstring claim that "the queued input is processed against the
+compacted history after the command completes."
+
+These tests pin that claim end-to-end for the classic CLI:
+
+1. ``test_type_ahead_queued_during_compress_becomes_next_prompt`` — runs
+   ``_manual_compress`` on a worker thread (matching the real topology:
+   slash commands execute on ``process_loop``, which is blocked inside
+   ``process_command`` for the duration), submits a type-ahead payload into
+   ``_pending_input`` mid-compression (what ``handle_enter``'s idle branch
+   does — ``_agent_running`` is False while a slash command runs), and
+   asserts that after compression commits the compacted history the queued
+   text is still the next item ``process_loop`` will drain. Nothing inside
+   the compression path may consume or drop it.
+
+2. ``test_handle_enter_never_gates_on_command_running`` — structural
+   invariant: ``handle_enter`` must not consult ``_command_running`` /
+   ``_command_blocks_input``. The composer's read-only state is enforced
+   solely by the TextArea's ``read_only=Condition(_command_blocks_input)``;
+   if a future edit added an early-return in ``handle_enter`` while a
+   command runs, type-ahead submissions would be silently dropped and the
+   drain contract above would break without any other test noticing.
+
+The Ink TUI (ui-tui) needs no equivalent fix: its ``/compress`` is an async
+``session.compress`` RPC and the composer is never made read-only while it
+runs; the gateway already resolves the concurrent-mutation race via the
+``history_version`` guard in ``_compress_session_history``.

+"""Regression tests for dotted config key names (#84064 bug class).
+
+Every issue in the family has a distinct repro shape, all rooted in the same
+unescaped ``key.split(".")``:
+
+* #84064 — ``providers.<name>.models.<model-with-dot>`` phantom siblings,
+  plus read-path (``config get``) and unset-path breakage.
+* #80006 — Matrix room IDs with dots under ``matrix.channel_prompts``.
+* #91095 — creation targets under a ``custom_providers`` list index where the
+  dotted model key already exists (``custom_providers.0.models.qwen3.5:4b``).
+* #91607 — ``model_overrides.zai.glm-5.3`` via
+  ``utils.py::atomic_roundtrip_yaml_update`` (a second split site).
+* #99124 — dotted leaf keys (``glm-5.3-flash``) across set/get/unset.
+
+Two complementary behaviors are covered:
+
+1. Backslash escaping via ``_split_key_path`` (carrier PR #84152).
+2. Greedy literal-key matching + loud phantom-sibling refusal, because dotted
+   model IDs are the norm and users won't know the escape syntax exists.

+"""Lint guard: no new raw yaml.safe_load(config.yaml) reads outside owner modules.
+
+The drift class this kills: scattered ``yaml.safe_load`` reads of the user's
+``config.yaml`` silently miss the managed-scope overlay, ``${ENV_VAR}``
+expansion, profile-aware pathing, and root-model normalization. Each new
+config feature has historically required an N-site sweep (incident chain:
+9cbcc0c9c8 → 732293cf87 → b0e47a98f9 → 1928aa0443).
+
+Canonical owners:
+
+  * ``hermes_cli/config.py`` — ``load_config()`` / ``load_config_readonly()``
+    (merged + managed + env-expanded), ``read_raw_config()`` and
+    ``read_user_config_raw()`` (the ONLY legal raw primitives: write-back
+    round-trips + raw-file diagnostics).
+  * ``gateway/config.py`` — the gateway's ``load_gateway_config`` owner.
+  * ``gateway/run.py`` — ``_load_gateway_config()``'s monkeypatched-home
+    fallback path (delegates to ``read_raw_config`` when paths agree).
+
+Everything else must import one of those. If this test fails on your new
+code, use ``load_config()``/``load_config_readonly()`` for behavioral reads,
+or ``read_user_config_raw()`` for write-back round-trips — do not add your
+file to the allowlist without a reason of the same class.

+"""Regression tests for issue #92993 — `curator pin` false success + invisible pin.
+
+Two stacked defects, each with its own failing assertion:
+
+1. **False success (write-path).** `_cmd_pin` gates on `is_agent_created()`
+   and then prints "pinned" unconditionally, but `set_pinned()` routes through
+   `_mutate(require_curation_eligible=True)`, which silently no-ops when
+   `is_curation_eligible()` is False. A skill can pass the first gate and fail
+   the second; the user sees "pinned" while nothing was written. The CLI must
+   detect the failed write and exit nonzero with a clear error.
+
+2. **Invisible pin (visibility).** `curator status` reads pins from
+   `curated_report()`, which only iterates `list_agent_created_skill_names()` —
+   and that list requires the `created_by: agent` management marker. A skill
+   that IS curation-eligible but carries no marker (pre-provenance record,
+   foreground-created) never appears as a row, so its pin is silently absent
+   from the status output even when successfully written.

+# strict cookie-aware proxy hops (verified for Go's net/http) reject,
+# dropping the cookie entirely (#83832, Traefik+Authentik field case).

+# the root: the payload is a dict, serialised as base64url(JSON) — the
+# urlsafe alphabet is a strict subset of the cookie-octets, and JSON
+# means no segment value can ever collide with a delimiter. Readers keep

+"""Path-prefix (X-Forwarded-Prefix) awareness for the dashboard-auth gate.
+
+Mission-control style deployments reverse-proxy the dashboard at a path
+prefix (e.g. ``mission-control.tilos.com/hermes/*`` -> local Caddy ->
+:9119), injecting ``X-Forwarded-Prefix: /hermes`` on every request.
+
+The dashboard already honours this for the SPA bundle (rewriting asset
+URLs and the bootstrap ``__HERMES_BASE_PATH__``). The OAuth gate must
+honour it too:
+
+  1. The gate's ``Location:`` redirect to /login (in
+     ``_unauth_response``) needs to be ``/hermes/login`` so the browser
+     follows it through the proxy.
+  2. The 401 JSON envelope's ``login_url`` needs the same prefix so the
+     SPA's full-page navigation lands at the proxied login page.
+  3. ``_redirect_uri`` (the OAuth callback URL handed to the IDP) must
+     reconstruct the public URL including the prefix, otherwise the IDP
+     redirects back to ``/auth/callback`` instead of
+     ``/hermes/auth/callback`` and the user gets 404.
+  4. Cookies must use ``Path=/hermes`` when behind a prefix so they
+     don't leak to other apps on the same origin AND so they get sent
+     back to the dashboard on subsequent requests under the prefix.
+  5. The ``__Host-`` cookie prefix requires ``Path=/`` — when behind an
+     X-Forwarded-Prefix we use ``__Secure-`` instead (matches every
+     hardening property except scope, which the explicit ``Path``
+     covers).
+
+These tests document the wire-level contract so a regression in any of
+those rules surfaces before a Mission Control deploy.

+The ``--tui`` flag was removed from the ``dashboard`` subcommand in cae6b5486
+(embedded chat is always on now). When a user's CLI updates past that commit
+but their desktop app binary has not, argparse used to reject the unknown flag
+with ``error: unrecognized arguments: --tui`` and ``exit(2)`` — the backend
+died before it became ready and the desktop GUI showed only "Hermes couldn't
+start" with no actionable cause.
+
+The fix adds a hidden, deprecated, accepted-and-ignored ``--tui`` flag to the
+dashboard subparser so an old app shell + new CLI degrades gracefully instead
+of bricking. These tests pin that contract.

+"""Tests for the configurable default interface (cli vs tui).
+
+`hermes` launches the classic prompt_toolkit REPL by default, but users can
+flip ``display.interface: tui`` in config.yaml to make the modern Ink TUI the
+default for bare ``hermes`` / ``hermes chat``. Explicit flags always win:
+
+    --cli                forces the classic REPL (highest precedence)
+    --tui                forces the TUI
+    (no TTY)             forces the classic REPL — ambient prefs don't apply
+    HERMES_TUI=1         the env default
+    display.interface    the configured default
+    (unset)              classic REPL
+
+The no-TTY gate exists because ambient TUI preferences must never hijack
+non-interactive invocations: kanban workers / cron / pipelines run
+``hermes … chat -q`` on a pipe, and the TUI's no-TTY bail-out exits 0
+without doing the work (a kanban worker then dies with "protocol
+violation" on every attempt).
+
+These tests pin that precedence at every layer that makes the decision:
+
+  * ``_resolve_use_tui(args)``  — the canonical args-aware resolver used by
+    ``cmd_chat`` and the Termux fast-TUI path.
+  * ``_wants_tui_early(argv)``  — the dependency-free early resolver used by
+    mouse-residue suppression and the Termux fast paths, before argparse and
+    ``hermes_cli.config`` are importable.
+  * the argument parser   — both ``--cli`` and ``--tui`` parse at the top
+    level and under the ``chat`` subcommand and are relaunch-inherited.

+"""LIVE Windows E2E for the Desktop-lifecycle cold-start skip (#76129/#76745).
+
+Runs ONLY on a real Windows host (the on-demand ``windows-venv-e2e.yml``
+lane). Exercises the REAL ownership predicate against REAL processes:
+
+ 1. A real child process self-registers in the REAL spawn ledger as a
+    ``serve`` purpose with THIS process as its live spawner — ownership
+    must hold, and ``_pause_windows_gateways_for_update`` must return None
+    (no cold-start plan) even with an autostart artifact present.
+ 2. Kill the child (dead serve) — ownership drops, the pause plan carries
+    ``cold_start_if_installed`` again.
+ 3. Venv-holder fallback rung: a real venv-python process with true
+    ``serve`` argv is detected by the scan and, having a live parent,
+    confers ownership; the token classifier rejects a ``kanban
+    --preserve-cache`` lookalike (the #90778 class the salvage fixed).

+before deduping. When two skills share the same 32-char prefix, only
+the first (alphabetical) wins; the second is dropped. Previously the
+drop was silent — the ``hidden`` count incremented but nothing named
+which skills collided, so authors had no way to discover the drop
+short of noticing that their skill was missing from the autocomplete.

+cmd_keys + the clamped name, so whoever named the skills sees the

+"""Regression tests for #34107 — Docker UID/GID handling in ensure_hermes_home.
+
+When Hermes runs in Docker with ``HERMES_UID=1000`` / ``HERMES_GID=911``,
+the entrypoint chowns the top-level ``HERMES_HOME`` once at startup. But
+subdirectories created at runtime by ``ensure_hermes_home()`` — especially
+for profile namespaces under ``profiles/<name>/`` spawned by kanban
+workers — were landing as ``root:root`` and blocking subsequent
+uid-mapped worker invocations with ``PermissionError [Errno 13]``.
+
+The fix is a ``_chown_to_hermes_uid`` helper that reads the env vars and
+applies chown after ``mkdir``, invoked from ``_secure_dir`` (which already
+runs after every directory creation in the home-init path).

+"""Exit watchdog: arm on shutdown *intent* (signal), never at chat startup.

+Regression coverage for the #65998 class: a ``hermes --tui`` process whose
+main thread wedges before ``app.run()`` returns never executes the ``finally``
+that calls ``_run_cleanup`` — the only place the exit watchdog used to be
+armed — so a "dead" CLI lingered indefinitely (observed ~47 min at 4% CPU).
+
+The fix arms the backstop from the SIGTERM/SIGHUP handlers via
+``_arm_exit_watchdog_on_shutdown_signal()``. Arming at *startup* (the
+rejected #65998 approach) is specifically forbidden: the watchdog thread
+calls ``os._exit(0)`` unconditionally after its sleep, so a startup-armed

+"""Regression tests: a slow gateway handoff dispatch must not be misreported
+as "gateway not running" — and no waiter may stomp a claimed (running) row.
+
+Bug shape (live-reproduced on main @1c5ee5815f): /handoff poll-waited a flat
+60s for a TERMINAL state. The gateway watcher claims within seconds, but the
+dispatch is a FULL synthetic agent turn (whole transcript replay + delivery)
+that routinely exceeds 60s. The CLI then printed "Timed out waiting for the
+gateway. Is `hermes gateway` running?" (false diagnosis), called
+fail_handoff() on the RUNNING row (stomping the gateway's claim), and claimed
+"Your CLI session is intact" after switch_session had already re-pointed the
+session. The gateway later overwrote failed -> completed: split-brain.
+
+Fix under test:
+  1. SessionDB.fail_handoff(only_states=...) — CAS: waiters can only fail
+     rows still in the given states.
+  2. CLI _handle_handoff_command: 60s deadline applies only to PENDING;
+     a RUNNING row gets a long (15 min) wait and is never failed by the CLI.
+  3. tui_gateway handoff.fail: only pending rows can be failed by Desktop.

+Codex's flags fully isolate a run from user-level config and exec-policy .rules
+files. In Hermes the equivalent isolation is:
+
+* ``--ignore-user-config`` → skip ``~/.hermes/config.yaml`` in ``load_cli_config()``
+  (credentials in ``.env`` are still loaded).
+* ``--ignore-rules`` → skip AGENTS.md / SOUL.md / .cursorrules auto-injection
+  and persistent memory (maps to ``AIAgent(skip_context_files=True,
+  skip_memory=True)``).
+
+Both flags are wired via env vars so they work cleanly across the
+argparse → cmd_chat → cli.main() → HermesCLI → AIAgent call chain.

+the user's personal FAL_KEY instead of the Nous Tool Gateway (real incident:
+personal key drained to zero while the subscription sat unused).
+
+Current contract (strict provider-string selection): each picker row writes
+exactly ONE provider string per category — ``image_gen.provider: nous`` for
+the managed "Nous Subscription" row, ``image_gen.provider: fal`` for the
+BYOK FAL row — and any legacy ``use_gateway`` key is popped so the

+"""Regression tests for #60920/#60941: interrupt marker duplication on redraw.
+
+The root cause: The interrupt marker ("_[Interrupted - processing new message]_")
+was being appended to the response string, which got recorded in _OUTPUT_HISTORY
+by the Panel rendering via _cprint → _record_output_history. When
+_recover_terminal_after_interrupt called _force_full_redraw → _replay_output_history,
+the marker was replayed on top of the already-visible message, causing duplicates
+that accumulated on every SIGWINCH.
+
+The fix:
+1. A flag ``_show_interrupt_marker`` is set instead of mutating ``response``.
+2. After the Panel rendering, the marker is printed via ``_cprint`` inside a
+   ``_suspend_output_history()`` context so it never enters ``_OUTPUT_HISTORY``.
+3. ``_recover_terminal_after_interrupt`` no longer clears ``_OUTPUT_HISTORY`` —
+   it doesn't need to, because the marker was never recorded.
+
+These tests verify the contract at the module level without hitting the full
+prompt_toolkit input loop.

+"""Regressions for domain-layer descendant invalidation on ancestor reopen.
+
+``kanban_db.invalidate_descendants_for_parent_reopen`` is the single
+implementation of "a done ancestor was reopened, retract everything that
+assumed its result" (M3). These tests pin:
+
+* done descendants are demoted to ``todo`` with a ``descendant_invalidated``
+  event AND a comment naming the ancestor (non-silent),
+* running descendants have their audit trail committed BEFORE their worker
+  is terminated, and the kill routes through ``_terminate_reclaimed_worker``
+  (the same helper the reclaim paths use),
+* ``consecutive_failures`` resets to 0 (deliberate operator action —
+  opposite of the review-loop rule pinned in M2), and
+* the dashboard ``_set_status_direct`` reopen path and the DB function
+  produce identical descendant outcomes.

+"""Review-lifecycle tests: the first-class ``running -> review`` transition.
+
+``request_review`` is the "implementation complete, awaiting review"
+transition used by executor workers instead of encoding ``review-required:``
+prose into a ``kanban_block`` call. The critical contract these tests pin
+down:
+
+* It transitions ``running``/``ready`` -> ``review`` and closes the active
+  run with ``outcome="review_requested"``.
+* It emits exactly one ``review_requested`` event carrying the handoff
+  summary + implementer.
+* Crucially, it is NOT a blocker: repeated review requests on the same task
+  (a review -> rerun -> review follow-up cycle) never touch
+  ``block_recurrences`` and never route to ``triage`` — the false
+  ``block_loop_detected`` escalation that plagued the block-reason approach
+  cannot happen.
+* ``expected_run_id`` is honoured as a CAS guard so a stale/superseded
+  worker cannot move the task.

+"""Tests for the Linux desktop sandbox-helper fixup and the userns probe.
+
+``_desktop_linux_sandbox_fixup`` historically demanded a root-owned 4755
+``chrome-sandbox`` on every Linux host and shelled out to ``sudo`` to get it
+— which fails silently when the desktop entry launches ``hermes desktop``
+without a TTY (#88032, #51327), and blocked the updater's relaunch gate
+(#58593). On hosts where unprivileged user namespaces work, Chromium uses
+its namespace sandbox and never consults the setuid helper, so the fixup now
+probes for that capability first and skips the sudo path entirely.

+"""Tests for ``list_picker_providers`` — the /model picker filter.

+- OpenRouter's ``models`` are replaced with the live-filtered output of
+  ``fetch_openrouter_models``, so IDs the live catalog no longer carries

+- Provider rows with an empty ``models`` list are dropped, except custom

+These tests exercise the filter in isolation by mocking

+"""Abandoned-request lifecycle: work sent to the managed local server must
+die when its caller goes away, and teardown must never orphan VRAM.
+
+The incident this guards: auxiliary calls (title generation + retries)
+queued at the router behind a cold model load, their clients timed out
+and hung up, and the router then dispatched them anyway. Non-streamed
+responses write the socket only after the FULL generation, so nothing
+noticed the dead clients — two uncapped decodes ran at full GPU for the
+better part of an hour with nobody listening.
+
+Three contracts, one per failure link:
+1. Auxiliary requests to the managed local endpoint are always streamed
+   (a dead client then cancels decode at the first chunk write).
+2. Explicit caller max_tokens caps reach the managed local endpoint
+   (title generation's 64-token cap must not be silently dropped).
+3. Supervisor teardown terminates the whole process tree, and a router
+   respawn reaps orphaned model children first (each holds GiB of VRAM).

+"""The recommendation decision table — the reviewable matrix.
+
+The recommendation itself is DERIVED (catalog.recommended_entry: best
+quality among resident entries clearing the pleasant speed floor, else
+fastest resident). Spilled models stay browseable but are never automatic
+recommendations, so nobody hand-maintains per-hardware-class picks.
+This table pins the model and reason across discrete and unified memory
+classes so changes to the recommendation remain reviewable.
+
+These are decision pins, not change-detectors: each cell is a choice a
+human approved, exactly like a golden file. When a cell flips on
+purpose, update it in the same commit and say why. When one flips by
+surprise, that is the test doing its job.
+
+Budgets mirror hardware.probe_budget's planning-mode shapes (margins,
+UMA headroom) so the cells match what a real machine of that class
+resolves.

+# - Discrete 24-96 GB: the 27B is the flagship experience — dense reads
+#   at ~1 TB/s clear the floor easily, so quality decides.
+# - Discrete/unified where Flash Next fits resident (128 GB discrete,
+#   256+ GB unified): the frontier model is the pick — highest quality,
+#   and its sparse decode clears the floor even at UMA bandwidth
+#   (~24 tok/s predicted at 210 GB/s).
+# - Unified 32-128 GB — the Spark class, the reason this resolver
+#   exists: the dense 27B predicts ~13 tok/s at UMA bandwidth (below
+#   the pleasant floor), so the 35B-A3B (~60 tok/s) wins.
+# - Unified <=24 GB: no entry passes the physics check inside the UMA
+#   budget (spilling is impossible on UMA by construction — the pool IS
+#   the RAM). The pane's browse flow is the path for those machines
+#   until a small catalog entry lands (revisit when one does).

+"""Tests for the dylib-complete macOS TCC anchor (issue #95596).
+
+Re-land of the interpreter anchor reverted in #95563.  The first landing
+bricked real Macs two ways: dynamically-linked builds died in dyld because
+``@executable_path/../lib/libpython`` resolved into ``venv/lib/`` (#95425),
+and alias symlinks to the copied interpreter lost the venv prefix (#95541).
+
+Linux tests use fake checkout/uv-store layouts with ``platform.system``
+monkeypatched.  The real-interpreter E2E is ``macos_only`` so it runs on
+the existing macOS CI job, not against one-byte fixtures.

+"""Regression test: ``hermes mcp add --command`` must not clobber the
+top-level ``args.command`` subparser dest.
+
+The top-level argparse parser uses ``dest="command"`` for its subparsers
+(``hermes_cli/_parser.py``).  The dispatcher in ``hermes_cli/main.py``
+reads ``args.command`` to decide which command to run; if it is ``None``
+it falls through to interactive chat.
+
+The ``mcp add`` subparser exposes a ``--command`` flag (the stdio command
+for an MCP server, e.g. ``npx``).  Without an explicit ``dest=``, argparse
+derives the dest from the flag name and writes ``args.command = None``
+when the flag is omitted, overwriting the top-level ``"mcp"`` value.  As a
+result, ``hermes mcp add foo --url ...`` silently launches chat instead
+of registering an MCP server.
+
+The fix: declare the flag with ``dest="mcp_command"``.  The CLI flag name
+is unchanged; only the in-memory attribute moves.
+
+We replicate the relevant parser shape here rather than importing the
+real builder, mirroring ``test_argparse_flag_propagation.py`` and

+When the CLI pushes ``ESC[>4;2m`` (modifyOtherKeys=2) to supported

+re-encodes EVERY Ctrl+key combo as ``ESC[27;5;<codepoint>~`` instead of

+"""Regression tests for ``_normalize_main_model_assignment`` (POST /api/model/set).
+
+Named custom providers are represented as ``custom:<name>`` slugs everywhere
+else in the codebase (``runtime_provider.py``, ``model_switch.py``), but
+``_KNOWN_PROVIDER_NAMES`` only lists the bare ``"custom"`` bucket. Before this
+fix, persisting a main-slot assignment for a named custom provider (e.g. a
+LiteLLM proxy fronting Ollama, registered as ``custom:litellm``) together with
+a slash-bearing model id (``ollama/glm-5.2``) was indistinguishable from the
+"vendor prefix posing as a provider" analytics-fallback case, and got silently
+rewritten to ``provider: openrouter`` in ``config.yaml`` -- reassigning the
+provider entirely, not just mangling the model id.
+
+A properly *configured* ``custom:<name>`` provider is now resolved earlier,
+via ``resolve_custom_provider`` against ``custom_providers``/``providers`` in
+config -- that's the primary, intended path and isn't this module's concern
+to re-test. What's tested here is the fallback safety net for when that
+resolution comes up empty (typo, config drift, entry removed) -- a
+``custom:<name>`` slug must still not be misread as a stray analytics vendor
+prefix and reassigned to openrouter, even though it isn't in
+``_KNOWN_PROVIDER_NAMES`` either.

+"""Regression tests for Nous Portal inference_base_url host-allowlist validation.
+
+A poisoned ``inference_base_url`` from a Portal refresh response (network
+MITM, malicious response injection) would otherwise be persisted to
+auth.json and forwarded with the user's legitimate invoke JWT
+bearer on every subsequent proxy request, exfiltrating their inference
+budget and opening a response-injection channel into the IDE / chat
+client. ``_validate_nous_inference_url_from_network()`` blocks any URL
+outside the allowlist at the source.
+
+These tests verify:
+
+1. The validator's host + scheme rules.
+2. Each of the two NETWORK call sites in ``auth.py`` calls the validator
+   rather than the unrestricted ``_optional_base_url`` helper.
+3. The proxy adapter applies the validator as belt-and-suspenders.
+4. The env-var override path (``NOUS_INFERENCE_BASE_URL``) is NOT
+   gated by the validator — that's the documented dev/staging escape
+   hatch.

+"""Regression tests for the Nous Portal env-override bypassing the host
+allowlist, mirroring the existing NOUS_INFERENCE_BASE_URL /
+_ALLOWED_NOUS_INFERENCE_HOSTS treatment.
+
+Real incident (2026-07): a hosted agent provisioned by nous-account-service
+on the `staging` Vercel environment is stamped with
+``HERMES_PORTAL_BASE_URL=https://portal.staging-nousresearch.com`` in its
+container env (the documented dev/staging override), while its bootstrap
+``auth.json`` ALSO persists ``portal_base_url`` to the same staging host.
+
+Before this fix, ``resolve_nous_access_token`` / ``resolve_nous_runtime_
+credentials`` read ``state.get("portal_base_url")`` FIRST via a plain ``or``
+chain, so whenever the stored state had ANY value the env vars were never
+even consulted — and whichever value won (state or env) was then run through
+``_NOUS_PORTAL_ALLOWED_HOSTS``, which only recognised the production host.
+The staging host was silently rewritten back to prod on every refresh, so a
+staging-issued refresh token got replayed against the PROD token endpoint.
+Prod correctly rejected that with ``invalid_grant``, which triggered
+``_quarantine_nous_oauth_state`` and wiped the entire credential pool.
+
+The correct fix (mirroring ``_nous_inference_env_override()``): the env
+override is a TRUSTED value the operator/deployment set themselves — it must
+win outright (even over a stored value) and bypass the allowlist entirely.
+The allowlist exists only to reject an untrusted NETWORK-provided value
+(a poisoned portal_base_url written to auth.json by a compromised Portal
+response), never a value the operator explicitly configured.

+"""Tests for `hermes -z --resume <session>` (#105892).
+
+The oneshot path used to accept ``--resume``/``-c`` in the parser but silently drop
+them: ``_run_oneshot_from_args`` ran before any session-arg normalization and never
+forwarded ``args.resume``, so every resumed one-shot turn started a FRESH session —
+the wire carried only ``[system, current user]`` and the model "forgot" everything.
+These tests pin the loader contract (chain redirect, unknown-session error,

+"""Regression tests for #88583 — one-shot resumed-session turns must persist.
+
+Bot Mode's bot-to-bot send (``hermes -p <bot> chat --in ~ -c "Bot Chat"
+--create-if-missing -Q -q "..."``) runs exactly one turn and exits. The
+receiving agent replied, the CLI banner said it resumed the titled session,
+but nothing landed in state.db when the turn's in-loop transcript flush
+failed transiently (write-lock contention with a multiplex gateway sharing
+state.db): the one-shot path had no end-of-run durable retry and never
+finalized the session row, unlike the interactive CLI (which retries on the
+next turn and ends the session with ``cli_close`` on quit).
+
+The fix routes every one-shot exit (quiet ``-Q -q``, human ``-q``, and the
+kanban SIGTERM path) through ``cli._flush_one_shot_session_store``: a final
+``_persist_session`` retry (idempotent via the per-message persisted
+markers), a token-count drain, and ``end_session(..., "cli_close")``.

+Real processes with real Hermes-shaped argv, real inventory collection
+(PID-file discovery + supervisor detection on REAL Windows), real
+reconciliation. No mocks on the components under test.
+
+ 1. Spawn a real process registered as a profile gateway (PID file + state
+    file in a temp HERMES_HOME) — real collect_runtime_inventory() must find
+    it, classify supervisor=manual, mechanism id 'manual'.
+ 2. Reconcile with bookkeeping that MISSES it -> unaccounted + escalation.
+ 3. Reconcile with it in killed_pids -> 'stopped', no escalation.
+ 4. Machine-id contract holds on Windows (no display strings leak in).

+Regression coverage for the cua-driver silent-no-op bug (issue #22737).
+
+When a no-key provider's only install side-effect is a `post_setup` hook
+(cua-driver, etc.), the gate function used to fall through to the
+`_toolset_has_keys` catch-all, which returned True for any provider with

+"""Regression coverage for GHSA-5qr3-c538-wm9j (#29156) — Remote Code
+Execution via the ``HERMES_ENABLE_PROJECT_PLUGINS`` bypass in the web
+server's dashboard plugin loader.
+
+Two primitives combined into the original advisory chain:
+
+1. ``hermes_cli.web_server_dashboard._discover_dashboard_plugins`` opted into
+   the untrusted ``./.hermes/plugins/`` source via
+   ``os.environ.get("HERMES_ENABLE_PROJECT_PLUGINS")`` — truthy for
+   any non-empty string, so ``=0`` / ``=false`` / ``=no`` (all of
+   which the agent loader treats as off, and which operators set to
+   *disable* project plugins) silently *enabled* the source.
+2. ``hermes_cli.web_server_dashboard._mount_plugin_api_routes`` then imported
+   each plugin's manifest ``api`` field as a Python module via
+   ``importlib.util.spec_from_file_location``.  The field was used
+   raw, with no path-traversal check, so a single manifest line
+   ``{"api": "/tmp/payload.py"}`` was enough to redirect the
+   importer at any Python file on disk (``Path('safe') / '/abs'``
+   resolves to ``/abs`` in Python).
+
+These tests pin each layer of the new defence:
+
+* Truthy env semantics now match the agent loader.
+* ``_safe_plugin_api_relpath`` rejects absolute paths, ``..``
+  traversal, and non-string / empty values.
+* ``_mount_plugin_api_routes`` re-validates at import time and
+  refuses project-source plugins outright.
+* End-to-end the original PoC manifest no longer triggers
+  ``importlib`` for ``/tmp/payload.py``.

+"""`hermes proxy` must resolve upstream credentials off the event loop.
+
+``UpstreamAdapter`` is a synchronous contract (``adapters/base.py`` — every
+method is a plain ``def``), and both shipped adapters implement it with
+blocking I/O:
+
+  * ``NousPortalAdapter.get_credential`` takes ``_auth_store_lock()``, a
+    *cross-process* advisory lock with ``AUTH_LOCK_TIMEOUT_SECONDS = 15.0``
+    (``hermes_cli/auth.py:110``), reads ``auth.json`` from disk, and may issue a
+    token-refresh POST. Its terminal-error path takes that lock a second time to
+    persist the quarantined state.
+  * ``NousPortalAdapter.get_retry_credential`` routes to that same
+    ``_get_credential`` with ``force_refresh=True``, so the refresh POST it only
+    *may* perform above is unconditional here.
+  * ``XAIGrokAdapter`` reads its key pool off disk under a ``threading.Lock``.
+    Its ``get_retry_credential`` loads the pool and calls
+    ``try_refresh_current`` / ``mark_exhausted_and_rotate`` under that lock.
+
+``create_app`` registers two ``async def`` handlers, so calling those methods
+directly from a handler freezes the proxy's single event loop — and with it
+every other in-flight streaming completion — for the whole duration.
+
+The primary assertions here are **thread identity**, not latency. A latency
+assertion measured with an HTTP client on the blocked loop is vacuous: the
+client's own timer cannot advance until the block ends, so it reports a fast
+response on code that was provably frozen. Thread identity has no such failure
+mode and no timing sensitivity.
+
+The harness mirrors ``tests/hermes_cli/test_proxy.py``: the proxy and a fake
+upstream run as real aiohttp servers on ephemeral ports, driven by
+``asyncio.run``. That keeps everything on exactly one event loop, which is what
+makes the loop-starvation observations meaningful, and it avoids taking a
+pytest-aiohttp dependency for one test file.

+"""Regression tests for the quarantine no-op restore gap (#75584).
+
+On Windows, ``_run_quarantined_install`` / ``_run_install_cmd`` rename live
+``hermes*.exe`` shims aside (``hermes.exe.old.<ms>``) before invoking the
+installer so uv/pip can write fresh replacements. When the install SUCCEEDS
+but never rewrites entry points (uv audits an already-satisfied editable
+install as a no-op), the old code only restored the shims on FAILURE — the
+quarantined shims stayed renamed aside and ``hermes`` vanished from PATH
+after a green install.
+
+These tests exercise both wrapper sites with a fake installer and assert the
+shims come back on every path:
+  - success + installer rewrote shims  → fresh shims kept, .old garbage left
+  - success + installer wrote nothing  → original shims renamed back (the bug)
+  - failure                            → original shims renamed back (as before)

+"""Regression tests: a failed quarantine restore must never strand `hermes`.

+On Windows the updater renames the live ``hermes*.exe`` shims aside
+(``hermes.exe.old.<unix-ms>``) so uv can write replacements. Gaps in the
+recovery path ended with ``hermes`` gone from PATH — and, because the command
+that repairs it IS ``hermes update``, unrecoverable without a manual reinstall
+(#75584):
+
+1. Restoring a shim got a single attempt whose ``OSError`` was swallowed in
+   silence, while the outbound quarantine rename already retried a lock.
+2. The startup sweep unlinked every ``*.exe.old.*``. When the original shim was
+   already missing, that .old file was the ONLY surviving copy — deleting it
+   converted a one-rename recovery into a full reinstall. It also raced a
+   concurrent in-flight update, destroying the quarantine that update's own
+   restore was about to rename back.
+
+These tests pin the hardened behavior: retry, rescue, report, order by parsed
+stamp, and leave files we did not create alone.

+line ~174 calls `setup_logging(mode="cli")` which transitively imports

+"""Regression tests for issue #81952 (silent OpenRouter paid-default class fix).
+
+When ``~/.hermes/config.yaml`` EXISTS but fails to parse, ``load_config()``
+falls back to ``DEFAULT_CONFIG`` — so ``resolve_provider('auto')``'s tier-2
+config check finds no ``model.provider`` and the tier-3 env sniff
+(OPENROUTER_API_KEY / OPENAI_API_KEY) or tier-4 pool probe silently adopts the
+PAID openrouter provider, even though the user's real (broken) config may name
+a completely different provider (e.g. ``openai-codex``). Real money, zero
+consent.
+
+The fix: ``hermes_cli.config`` records active parse failures
+(``get_active_config_parse_failure``), and ``resolve_provider`` refuses
+env/pool auto-adoption with ``AuthError(code='corrupt_config')`` while the
+active config is corrupt. Explicit provider requests and valid-config
+env-sniff flows are untouched, and fixing the file in place clears the block.

+"""Legacy NULL-profile session owner backfill (#94724).

+Pre-#95407 session rows carry ``profile_name = NULL``. Once a Desktop has
+registry topology (≥2 registered connections) the fail-closed owner ladder
+can no longer route those rows, making every pre-campaign session
+unresumable. POST /api/sessions/owner-backfill stamps each store's own
+serving-profile identity onto its legacy rows — single-match by construction
+(a profile's state.db belongs to exactly one profile), idempotent, and never
+overwriting a non-NULL owner.

+"""Regression test for #28181 — kanban worker SIGTERM must terminate the process.
+
+The single-query signal handler in cli.py (``_signal_handler_q``) raises
+``KeyboardInterrupt`` to unwind the main thread on SIGTERM/SIGHUP. That works
+for interactive ``hermes chat -q`` invocations, but kanban workers spawned by
+the dispatcher are likely to have a non-daemon thread alive (terminal_tool's
+``_wait_for_process``, custom plugin background workers, etc.). With
+``KeyboardInterrupt`` only the main thread unwinds; the non-daemon thread
+keeps the process alive after the gateway has already restarted, the kanban
+dispatcher's ``_pid_alive`` check returns True forever, and the task stays
+``running`` indefinitely.
+
+The fix: when the process is a dispatcher-spawned worker (``HERMES_KANBAN_TASK``
+env var set), flush logging + stdout/stderr and call ``os._exit(0)`` instead.
+The kernel reclaims the PID immediately, and ``detect_crashed_workers``
+reclaims the stale claim on the next dispatcher tick.
+
+These tests use a synthetic Python script that mirrors the cli.py signal
+handler shape so we can exercise the exit-path contract without booting the
+full CLI (which needs a real provider config).

+"""Regression tests for #30768, #32383, and #33961.
+
+``_prompt_text_input_modal`` answers destructive-slash confirmations through a
+queue-based modal driven by prompt_toolkit key bindings.  When invoked from the
+``process_loop`` daemon thread it sets the modal up on the app's event loop via
+``call_soon_threadsafe``, so it is safe on every platform — including native
+Windows (#33961), where the earlier ``sys.platform == "win32"`` → raw ``input()``
+fallback deadlocked the daemon thread against prompt_toolkit's stdin ownership.
+
+These tests verify:
+1. Daemon-thread confirm uses the modal via the app loop — never the raw stdin
+   fallback, never a hang. Since the #33961 fix this path is platform-agnostic,
+   so it runs on the host as-is.
+2. Main-thread confirm with a running app uses the modal.
+3. The raw stdin fallback is kept ONLY for the safe cases: no running app, and
+   (on win32, off-thread) a scheduling failure degrades to a clean cancel.
+4. Empty choices returns None.
+
+**Why the Windows cases are ``windows_only`` rather than ``sys.platform``
+patches.** The deadlock #33961 fixed is a real property of the Windows console:
+a raw ``input()`` off the main thread blocks forever against prompt_toolkit's
+stdin ownership. On Linux the same call returns immediately (or EOFs), so a test
+that patches ``sys.platform`` to ``"win32"`` proves only that we took the
+``if``-branch — the hazard the branch exists to avoid isn't present on the host.
+The one remaining platform-specific behaviour is the ``_stdin_fallback``
+win32-and-off-main-thread clean-cancel; those tests are marked and run on the
+Windows CI job.

+"""#100368 regression: the corruption guidance must not direct a WAL-reset-
+vulnerable sqlite3 CLI at a live Hermes database.
+
+Field forensics (issue #100368, maintainer round 2 + the isolated reproducer
+in its comments): when a shell with SQLite's WAL-reset opener bug (fixed
+3.51.3+ / backports 3.50.7 / 3.44.6 — Debian/Ubuntu system CLIs 3.45.1 /
+3.46.1 are in the vulnerable band) opens a live state.db whose writer's DMS
+lock has been cancelled, it unlinks the live -wal/-shm pair and splits the
+store into two concurrent generations. Both generations report
+``integrity_check ok`` while an old-generation acknowledged write is lost.
+
+Hermes' own corruption banners used to instruct exactly that command
+(`sqlite3 ~/.hermes/state.db ".recover"`). The fix routes operators to
+`hermes sessions recover --source ...`, whose lane snapshots the damaged
+bundle before any shell touches it, and refuses a WAL-reset-vulnerable
+sqlite3 CLI for the page-level salvage lane even on the snapshot.

+"""Regression guard for issue #34569 — inline /steer (and /model) submit
+must repaint the input area after clearing the buffer.
+
+Mechanism of the bug
+--------------------
+``handle_enter`` dispatches ``/steer`` (and ``/model``) inline on the UI
+thread while the agent is running.  Those branches called
+``buffer.reset(append_to_history=True)`` but — unlike every *other*
+early-return branch in the handler — did NOT call ``event.app.invalidate()``.
+Because ``process_command()`` prints through ``patch_stdout`` (which scrolls
+output above the prompt and never triggers a prompt_toolkit redraw), the
+just-cleared input area could keep showing the submitted ``/steer <text>``
+until some unrelated redraw fired.  The user saw their submitted text as if
+it were unsent and could accidentally re-submit it.
+
+This test pins the contract structurally: inside ``handle_enter``, any
+inline-command early-return that resets the buffer must be followed by an
+``event.app.invalidate()`` before its ``return``.  It is an *invariant*
+(every reset-then-return repaints), not a snapshot of current source.

+"""Tests for systemd optional-directive normalization (issue #41119).
+
+On older systemd versions that don't support RestartMaxDelaySec /
+RestartSteps, the installed unit file has those directives silently
+dropped.  Without normalization, systemd_unit_is_current() would
+perpetually report the unit as outdated because the strict text

+"""Regression: the terminal config→env re-bridge is scoped to the *true*
+process profile, never a per-task ``set_hermes_home_override``.
+
+The multiplex dashboard serves every profile on the host from one process,
+so ``os.environ`` is shared across all of them. A per-turn handler scoped to
+a secondary profile (via ``set_hermes_home_override``) must NOT cause that
+profile's ``terminal.backend`` to be bridged into the shared environment —
+otherwise a ``local`` sibling profile silently clobbers the launch profile's
+``TERMINAL_ENV=ssh`` (leaving its ``TERMINAL_SSH_*`` intact), and the launch
+session runs every command locally instead of over SSH.
+
+The guard in ``env_loader._reapply_terminal_config_bridge`` compares the
+loaded home against the process home. It must use the override-immune
+``get_process_hermes_home()`` so the comparison reflects the launch scope,
+not whichever profile the current task is scoped to.

+"""Regression tests for #33271: terminal recovery after interrupt.
+
+When the user interrupts a running agent turn by typing a new message,
+prompt_toolkit may have an in-flight ``CSI 6n`` cursor-position query whose
+reply (``ESC[<row>;<col>R``) arrives on stdin after the input parser has torn
+down. The reply then leaks as literal text (``^[[19;1R``) and the VT100 parser
+can stall, accepting no further keystrokes — the terminal appears frozen.
+
+The recovery path lives in ``HermesCLI._recover_terminal_after_interrupt()``,
+which is invoked from ``process_loop``'s ``finally`` block only when
+``self._last_turn_interrupted`` is set. It must:
+  1. Drain stray escape bytes from the OS input buffer (``flush_stdin``).
+  2. Force a clean prompt_toolkit renderer redraw (``_force_full_redraw``).
+
+These tests exercise the real method (not a re-implementation of its logic),
+and assert that the finally block actually wires it in behind the interrupt
+guard.

+"""The unified-pool vendor quirk must never misclassify a discrete card.
+
+On unified-memory NVIDIA devices under Windows, nvidia-smi answers from
+a WDDM carve-out while the CUDA allocator addresses the whole pool at
+full bandwidth. Budgeting from smi there produces false "larger than
+your GPU memory" rows and -ot CPU pinning that measures far slower than
+letting the allocator place everything.
+
+The other direction is the regression this file guards: a workstation
+card must never be budgeted as UMA. The driver's INTEGRATED attribute
+decides when readable (both directions); the attribute-less engine
+fallback needs two independent numeric gates, each alone unmeetable by

+"""Tests for the /update slash command in the classic CLI and TUI launcher.

+Verifies that ``HermesCLI._handle_update_command`` correctly:
+- Refuses to run under a managed install (Homebrew, Docker, etc.)
+- Sets ``_pending_relaunch`` and returns ``True`` on confirmation
+- Cancels cleanly on a "no"-shaped answer or unrecognized input
+- Cancels cleanly when ``_prompt_text_input_modal`` returns None (timeout /
+  modal dismissed)
+
+Also verifies that ``main_tui_launch._launch_tui`` correctly handles exit
+code 42 (the TUI's signal to trigger an update) by calling
+``relaunch(["update"], preserve_inherited=False)`` from the Python wrapper
+side.  The companion Vitest (``ui-tui/src/__tests__/createSlashHandler.test.ts``)
+covers the TypeScript slash-handler that *emits* code 42; this file covers
+the Python wrapper branch that *acts on* it.

+"""Regression tests for #100179: cron-update three-way restart deadlock.
+
+When `hermes update` runs INSIDE the gateway's own process tree (the
+hermes-auto-update cron job), waiting for that gateway to exit is a
+circular wait:
+
+  gateway waits on all in-flight work units (#77184)
+    -> cron agent session waits on the `hermes update` process
+      -> `hermes update` waits on the gateway to exit  [back to A]
+
+The wedged-loop probe cannot break it: the cron session posts activity
+every ~180s (process-tool poll return), so it is never marked wedged and
+the gateway burns the full 1800s force-drain cap.
+
+The fix: when the target gateway PID is an ancestor of this process,
+fire-and-forget (SIGUSR1 + return) instead of drain-waiting.

+"""Regression for #93406 (residual) — the Windows pause/resume token is NOT a
+fleet runtime and must not be counted by ``_fleet_probe_expected_runtimes``.
+
+The first #93406 guard counted the ``_windows_gateway_resume`` token
+(``profiles`` / ``unmapped`` entries) as an "expected fleet rows" signal. But
+the token is pause/resume *bookkeeping*, not a runtime inventory:
+
+* ``unmapped`` entries (Scheduled-Task gateways) never publish
+  ``gateway_state.json`` rows at all, and
+* a paused-then-resumed profile gateway relaunches DETACHED and may not
+  republish its identity within the probe's window,
+
+so ``collect_fleet_versions()`` can legitimately return zero rows for a
+perfectly healthy Windows update. With the token counted as an expected
+runtime, ``_fleet_rows_expected`` is True, the verification loop silently
+waits out its polling window (~14 min wall clock on an end-user report with
+the retry loop), prints "Fleet version check returned no rows", and ``hermes
+update`` exits 1 — for an update that succeeded.
+
+The invariant this file pins: ``_fleet_probe_expected_runtimes`` may only
+return True for signals that correspond to rows ``collect_fleet_versions()``
+is actually capable of returning (restart-phase bookkeeping, the pre-restart
+PID snapshot, the pre-update plan inventory). A genuinely live pre-update
+Windows gateway is already covered by ``pre_restart_pids`` and the plan
+inventory — the token adds no row-capable information on top.
+
+Counterfactual: every test in ``TestResumeTokenIsNotARuntime`` FAILS on the
+pre-fix ``_fleet_probe_expected_runtimes`` (which returns True for a
+token-only signal).

+"""Regression for #78574 — a crashed gateway-restart phase must not stay silent.
+
+``hermes update`` wrapped its entire gateway auto-restart phase in a blanket
+``except Exception`` that only logged at debug level. When the phase raised
+early (e.g. importing ``hermes_cli.gateway`` from the freshly pulled checkout
+inside a process that already loaded the pre-update modules), every drain and
+restart line vanished from the update output, the update printed
+"Update complete!" and exited 0 — while the still-running default-profile
+gateway kept serving pre-update modules and died on the next turn with
+``ImportError: cannot import name 'is_trivial_prompt'``.

+"""Tests for the GUI-updater hand-off backend reap (_handoff_reapable_backend_pids).
+
+Field incident (2026-08-20, Teknium's Windows box): a Desktop update hand-off
+(`hermes update --yes --gateway --force`) left a *swarm* of per-profile `serve`
+backends (mr-tester, probe-inherit, turqoise, clippy, maroon, …) holding
+`cryptography\\_rust.pyd`. Some still had a live parent (the tearing-down
+Electron process, or the venv launcher→worker two-hop chain mid-exit), so the
+strict orphan-only reap (_orphaned_desktop_backend_pids) disqualified the whole
+set and the update dead-ended — a 12-minute hang, then a force-close that
+stranded bot sessions.
+
+_handoff_reapable_backend_pids is the additional rung that ONLY runs in the
+hand-off context (caller gates on args.gateway + the update-incomplete marker +
+no live hermes.exe shim). There, any surviving Hermes `serve`/`dashboard`
+backend from this venv is a leak — live parent or not — and safe to reap.
+A non-backend holder still disqualifies the whole set.
+
+Runs on any host via a fake psutil module (same approach as
+test_update_orphan_backend_reap.py).

+"""Regression for #41403 — ``hermes update`` must restart ALL macOS launchd gateways.
+
+The macOS branch of the update's fleet-restart step only restarted the
+invoking profile's LaunchAgent (``get_launchd_label()`` is profile-scoped).
+Sibling ``ai.hermes.gateway-<profile>`` services kept running pre-update
+modules cached in ``sys.modules`` and died on their next agent turn once the
+new code lazily imported a symbol the old module generation didn't have
+(``ImportError: cannot import name ...`` — or, with a wider version gap,
+``TypeError``/``AttributeError`` on changed call signatures with garbled
+tracebacks, because the source files on disk no longer match the loaded
+code objects).
+
+Also covers the launchd-domain review feedback on PR #41403: every sibling
+interaction (liveness discovery, kickstart, fresh-PID verification) must be
+domain-explicit — ``_launchd_domain()`` caches the *current* profile's
+domain, and a sibling bootstrapped in the other supported domain
+(``gui/<uid>`` vs ``user/<uid>``) would otherwise be probed or kickstarted
+in a domain it does not live in.

+"""Regression for #88848 - a launchd restart the update never verified.
+
+``hermes update`` on macOS printed ``Update complete!`` and exited 0 while the
+``ai.hermes.gateway`` LaunchAgent sat deregistered for 36 minutes.  The restart
+phase treated "``launchd_restart()`` returned without raising" as success and
+appended the label to ``restarted_services``.  Both of launchd_restart's normal
+outcomes are asynchronous - the ``_request_gateway_self_restart`` branch returns
+the instant the running gateway is *asked* to restart, and a plist reload is
+handed to a detached helper - so a helper that died before its first bootstrap
+was invisible to the caller.
+
+The systemd branch of the same phase has never drawn that inference: it polls
+``_wait_for_service_active`` before recording the unit and routes a unit that
+never came back into ``failed_or_stale_units``, which is what makes the update
+exit non-zero.  These tests pin the same contract for launchd.
+
+No macOS hardware is involved: every case drives the seam through mocked
+``launchctl`` outcomes.

+"""Tests for the orphaned-Desktop-backend reap in the venv-holder guard.
+
+The GUI-updater handoff race (ryanc's 2026-08-09 failures): the Desktop app
+fires SIGTERM + app.quit() and spawns hermes-setup, but its Python backend
+(``python.exe -m hermes_cli.main serve``) survives the teardown race. The
+Desktop is gone — nothing will respawn that backend — yet the venv-holder
+guard refused on it and the update dead-ended with "Hermes is still running"
+while the user had zero windows open.
+
+``_orphaned_desktop_backend_pids`` classifies holders: a ``serve``/
+``dashboard`` backend whose supervising parent is provably dead is safe to
+reap (with its full child tree — the managed .hermes-runtime interpreter
+child included, #70026); anything else keeps the refusal.
+
+All paths run on any host via a fake psutil module (same approach as
+test_update_venv_health.py).

+"""Truthfulness invariants for the update pipeline at the RECEIPT layer.
+
+Bug class ("update reports success while reality disagrees" — #88654,
+#88848, #91378, #91439, #91962, #92780, #92902): the updater's word must be
+backed by evidence. This suite pins the honesty contract of the receipt
+subsystem with REAL module functions against a temp HERMES_HOME — it is not
+a fleet E2E (that lives in the CI install/update harness).
+
+Invariants pinned, and WHERE each is enforced:
+
+1. RECEIPT ALWAYS FINALIZED — ``begin → steps → finalize`` writes a
+   parseable receipt for success/failed/refused (#91283 made every
+   post-begin run leave a record). A begun-but-never-finalized run
+   (simulated crash) writes NOTHING to disk, so the reader the Desktop
+   uses (``read_latest_receipt``, surfaced via
+   ``/api/hermes/update/receipt`` — #92780) can never interpret a crash
+   as success. The HTTP-layer gating of an ``outcome == "running"``
+   receipt is already pinned in test_update_receipt_endpoint.py and is
+   deliberately not duplicated here.
+
+2. SUCCESS IMPLIES ACCOUNTING — #92902 made the pre-update plan the
+   restart worklist. The final refuse-success decision is INLINE in
+   ``_cmd_update_impl`` (update_cmd.py ~8331-8373, a 8.5k-line flow), so
+   the deepest extractable real functions are pinned instead:
+   ``match_runtime_outcomes`` (plan-vs-bookkeeping reconciliation) and
+   ``report_unaccounted_runtimes`` (the escalation decision). The
+   command's outcome selection is exactly
+   ``"partial" if incomplete else "success"`` (update_cmd.py ~8360); the
+   tests drive that expression with the real decision function's return
+   value, so sabotaging the enforcement (making it accept a missed
+   runtime) fails these tests.
+
+3. REFUSAL IS NOT FAILURE — #91439: an exit-2 preflight refusal must
+   produce a receipt distinguishable from a failed update, and the
+   reader must report it as ``refused``.
+
+Only paths/env are monkeypatched; every receipt is produced by the real
+``hermes_cli.update_receipt`` / ``hermes_cli.update_inventory`` API.

+"""Regression coverage for the updater self-lock deferral (#83569, #86735).
+
+``_detect_venv_python_processes`` excludes the calling process and its
+ancestors by design — a CLI ``hermes update`` IS the venv python.  Before
+this guard, an updater that had already imported a native venv extension
+(e.g. ``cryptography.hazmat.bindings._rust``) died mid-sync with
+``os error 5`` when ``uv`` tried to replace the mapped ``.pyd``, stranding
+the venv half-updated (#83569).
+
+The first version of the guard (#86687) fired as a PRE-FETCH preflight and
+keyed on nothing but "is the module in sys.modules" — which was ALWAYS true
+while ``bitwarden.py`` imported cryptography at module level, so every
+Windows ``hermes update`` exited 2 before even fetching and the update
+looped forever (#86735 / #86780 / #86781).  The guard is now honest:
+
+* it only reports a loaded module when the dependency sync would actually
+  REWRITE that distribution (``_dependency_sync_would_rewrite`` — installed
+  version vs the on-disk pyproject pins);
+* it runs AFTER the code swap, immediately before the venv rewrite
+  (``_abort_dependency_sync_if_self_locked``), so a deferral leaves the
+  user on NEW code with only the dependency install pending.

+"""Regression coverage for stale ``hermes serve`` generations after an abort.
+
+Issue #92145: ``hermes update`` moves the checkout from generation N to N+1
+while the updater still holds the pre-pull module graph.  When the in-process
+restart phase raises, a fresh process retries the *gateway* profiles — but
+``hermes serve`` is not a gateway profile.  It hosts ``tui_gateway.server``,
+systemd lists ``hermes-gateway.service`` before ``hermes-serve.service`` (so
+the serve unit is the one an abort typically never reaches), and the final
+read-back (``collect_fleet_versions``) only inspects gateway state.  A serve
+process left on generation N is therefore invisible to every check, and the
+update reports a clean recovery while every chat turn fails with an
+``ImportError`` for a symbol that imports fine on disk.
+
+These tests pin the closure predicate: no runtime from the pre-update
+inventory may still be the same process once recovery reports success, and
+nothing without a verified relaunch authority may be killed to get there.

+"""The Windows console-shim update self-lock (#88838, #89599, #86093).
+
+``venv\\Scripts\\hermes.exe`` is a launcher that runs the interpreter with the
+shim itself as its script, keeping the file open without FILE_SHARE_DELETE for
+the whole command. An update started that way must therefore replace a file it
+is holding, which Windows refuses — so the DEPENDENCY SYNC re-runs itself under
+``venv\\Scripts\\python.exe``.
+
+The hand-off sits at the sync boundary, not at the top of ``hermes update``:
+everything before it (the fetch, the stash question, the branch switch) runs
+in the user's own console, and an up-to-date run that never syncs never hands
+off at all.
+
+``_is_windows`` is patched so these paths are exercised on any host.

+"""Tests for the wedged-gateway health probe + bounded escalation (#81642).
+
+A gateway whose event loop is stalled cannot process a graceful shutdown, so
+the updater's drain wait used to burn the full 180s budget ("Gateway PID X
+still running after 180.0s — restart may fail") and could deadlock `hermes
+update`. The fix probes the loop-liveness heartbeat file BEFORE draining and,
+only when the loop is provably dead, escalates SIGTERM → SIGKILL bounded to
+seconds. A busy-but-alive gateway (fresh heartbeat) must keep the full drain
+path — including the in-flight cron drain floor from #86684.

+"""Regression tests for the OAuth dispatcher in hermes_cli.web_server.
+
+Bug history (2026-05-09): the `_OAUTH_PROVIDER_CATALOG` had two entries
+flagged ``flow: "pkce"`` — anthropic and minimax-oauth — and the
+dispatcher ``start_oauth_login`` hardcoded ``_start_anthropic_pkce()``
+for any pkce-flagged provider. So clicking "Login" next to MiniMax in
+the dashboard's Keys tab silently launched the Anthropic/Claude OAuth
+flow. The Anthropic dashboard flow was later removed entirely because
+Hermes must not mint subscription OAuth tokens from an unattended HTTP
+endpoint; only the approved external CLI path remains.
+
+The fix:
+  1. Catalog entry for minimax-oauth changed from ``flow: "pkce"`` to
+     ``flow: "device_code"`` (the actual UX is verification URI + user
+     code + background poll, with PKCE as a security extension).
+  2. New MiniMax branch added to ``_start_device_code_flow``.
+  3. Anthropic's catalog entry changed to ``flow: "external"`` and its
+     dashboard start/submit routes now reject the removed flow. Any future
+     provider added without an explicit flow gets a clean error instead of
+     silently launching Anthropic OAuth.
+
+These tests pin the corrected behavior.

+"""Approvals config saves must re-emit session.info to live gateway sessions.
+
+Regression for the desktop "YOLO toggle does nothing / flips back off" bug:
+the settings page saves ``approvals.mode`` through REST ``PUT /api/config``
+(and the raw editor through ``PUT /api/config/raw``), which wrote config.yaml
+and emitted nothing. Enforcement follows the file immediately (the approval
+gate re-reads config per command), but every live session's YOLO/approval
+indicator repaints only on a ``session.info`` event, so the UI kept showing
+stale bypass state, in the dangerous direction. The ``config.set`` RPC path
+already re-emits after a mode flip; these tests pin the REST paths to the

+Integration tests for the desktop boot handshake fix (PR #50231 / issue #50209).
+
+Simulates a slow hermes_cli.gateway import (15-30 s on a fresh Windows install
+with Defender scanning every new .pyc) by patching the two helpers that touch
+the blocking import and measuring response latency.
+
+Three scenarios are covered:
+
+1. _lifespan synchronous warmup: patched _warm_gateway_module sleeps N seconds;
+   TestClient startup blocks for >= N seconds (intentional — see #73083/#73291:
+   the import doesn't release the GIL on Windows + Python 3.11, so
+   run_in_executor still froze the event loop. Absorbing the cost before the
+   lifespan yield ensures the server socket doesn't accept probes until the
+   import is complete).
+
+2. get_status run_in_executor: patched _resolve_restart_drain_timeout sleeps N
+   seconds in a thread; a concurrent fast endpoint (/api/version) must respond
+   during the wait, proving the event loop stayed free.
+
+3. No orphan accumulation: three concurrent /api/status requests all receive a
+   200 response — no socket timeouts, no connection resets.

+"""Unit tests for hermes_cli.win_pty_bridge — ConPTY spawning + byte forwarding.
+
+Windows-only counterpart to tests/hermes_cli/test_pty_bridge.py.  Drives
+``WinPtyBridge`` with minimal Windows processes (``cmd.exe``, ``python -c …``)
+to verify it behaves like a PTY you can read/write/resize/close, then a small
+set of platform-fallback assertions (``is_available``, ``PtyUnavailableError``)
+that run on every OS so the import surface stays exercised in CI.
+
+The bridge is the ConPTY backend behind the dashboard ``/chat`` tab — see
+``hermes_cli/web_server.py`` ``/api/pty`` handler — so these tests are the
+unit-level half of the integration check that the dashboard chat pane is
+actually live on native Windows.

+"""Regression tests for #48820 (4th repro): job-object teardown killed the
+post-update respawned gateway silently, and the updater printed
+"✓ Restarting Windows gateway profile(s)" anyway.
+
+Two fixes under test:
+
+1. ``_spawn_gateway_restart_watcher``'s inlined watcher source must
+   (a) route the respawned gateway's stray stdout/stderr to
+       ``logs/gateway-stdio.log`` (it was ``DEVNULL`` — a gateway killed by
+       parent Job Object teardown left ZERO trace anywhere), and
+   (b) stamp ``_HERMES_GATEWAY_BREAKAWAY`` =1/0 on the respawn env exactly
+       like the canonical ``gateway_windows._spawn_detached``, so the
+       lifecycle/exit-diag records show whether the gateway escaped the
+       parent's Job Object.
+
+2. ``_resume_windows_gateways_after_update`` must verify a stable gateway
+   process actually exists (via ``gateway_windows._wait_for_gateway_ready``)
+   before printing the ✓ — a truthy launch return only proves the watcher
+   process was created, not that the respawned gateway survived the
+   updater's Job Object teardown.

+fallback (profile -> credential pool -> global root). These cover the WRITE
+side: when a profile that has no own ``providers.xai-oauth`` block refreshes
+the (rotating) grant it resolved from the root fallback, the rotated tokens
+must be written back to the global root too. Otherwise root keeps a revoked
+refresh token and every other profile reading root's stale grant dies with
+``invalid_grant`` once its access token expires (issue #43589).
+
+The tests drive the real ``_save_xai_oauth_tokens`` against real on-disk auth
+stores (profile + root under ``tmp_path``) rather than mocking the save
+boundary, so they exercise the actual atomic write path.

+📋 PROBLEM SUMMARY
+------------------
+Current implementation uses pool.map() which blocks until ALL batches complete.
+Checkpoint is only saved after all batches finish (line 558-559).
+
+If process crashes during batch processing:
+- All progress is lost
+- Resume does nothing (no incremental checkpoint was saved)
+
+📋 PROPOSED SOLUTION
+--------------------
+Replace pool.map() with pool.imap_unordered() to get results as they complete.
+Save checkpoint after EACH batch completes using a multiprocessing Lock.
+
+Key changes:
+1. Use Manager().Lock() for thread-safe checkpoint writes
+2. Replace pool.map() with pool.imap_unordered()
+3. Update checkpoint after each batch result
+4. Maintain backward compatibility with existing checkpoints
+
+📋 IMPLEMENTATION STEPS
+-----------------------
+1. Add Manager and Lock initialization before Pool creation
+2. Pass shared checkpoint data and lock to workers (via Manager)
+3. Replace pool.map() with pool.imap_unordered()
+4. In result loop: save checkpoint after each batch
+5. Add error handling for checkpoint write failures
+
+📋 RISKS & MITIGATIONS
+----------------------
+Risk: Checkpoint file corruption if two processes write simultaneously
+→ Mitigation: Use multiprocessing.Lock() for exclusive access
+
+Risk: Performance impact from frequent checkpoint writes
+→ Mitigation: Checkpoint writes are fast (small JSON), negligible impact
+
+Risk: Breaking existing runs that are already checkpointed
+→ Mitigation: Maintain checkpoint format, only change timing
+
+Risk: Bugs in multiprocessing lock/manager code
+→ Mitigation: Thorough testing with this test script
+
+📋 TESTING STRATEGY
+-------------------
+1. Run test_current_implementation() - Confirm bug exists
+2. Apply fix to batch_runner.py
+3. Run test_current_implementation() again - Should see incremental updates
+4. Run test_interruption_and_resume() - Verify resume works
+5. Manual test: Start run, kill process mid-batch, resume
+
+📋 ROLLBACK PLAN
+----------------
+If issues arise:
+1. Git revert the changes
+2. Original code is working (just missing incremental checkpoint)
+3. No data corruption risk - checkpoints are write-only

+"""Docker integration tests for the vision image-source resolver.
+
+Exercises the in-sandbox exec-read path that unit tests can only mock. Two
+scenarios that ONLY the container filesystem can serve:
+
+  * a tmpfs ``/workspace`` file with no host path at all, and
+  * a root-owned mode-600 file the host user cannot read,
+
+both delivered by the resolver's ``base64`` exec-read fallback
+(``tools/image_source._resolve_container_fallback``). This is the same path
+that provides terminal-backend confinement for GHSA-gpxw-6wxv-w3qq: under a
+non-local backend a non-cache path is read INSIDE the container, never on the
+host.
+
+Gating follows the repo convention: the ``integration`` marker excludes these
+from the default suite (``addopts = -m 'not integration'`` in pyproject.toml);
+they run under ``pytest -m integration`` when a Docker daemon is available and
+skip cleanly when it is not. Container spin-up exceeds the 30s suite default,
+so the timeout is bumped to 180s.

+Run:  pytest -m integration tests/integration/test_vision_docker_resolve.py

+Comprehensive Test Suite for Web Tools Module
+
+This script tests all web tools functionality to ensure they work correctly.
+Run this after any updates to the web_tools.py module or backend libraries.
+
+Usage:
+    python test_web_tools.py              # Run all tests
+    python test_web_tools.py --no-llm     # Skip LLM processing tests
+    python test_web_tools.py --verbose    # Show detailed output
+
+Requirements:
+    - PARALLEL_API_KEY or FIRECRAWL_API_KEY environment variable must be set
+    - An auxiliary LLM provider (OPENROUTER_API_KEY or Nous Portal auth) (optional, for LLM tests)

+- v1.0 SSE StreamResponse format (member-name discrimination, no kind/final)
+- message/stream and tasks/subscribe end-to-end against a live server
+- Push notification HMAC signing
+- Anti-loop ping-pong protection (TurnTracker + live rejection)
+- Rate limiting (per-identity sliding window)
+- Metrics collection (real latency)
+- Task store (idempotent completion, watchers, orphan handling)
+- Dynamic Agent Cards from the live tool registry
+- Capability-based routing with fan-out (a2a_orchestrate)

+"""Tests for the bundled hermes-achievements dashboard plugin.
+
+These target the two behaviors that matter for official integration:
+
+* The 200-session scan cap is removed — the plugin now walks the entire
+  session history by default. Lifetime badges (tens of thousands of
+  tool calls) were unreachable before this fix on long-running installs.
+* First-ever scans run in a background thread so the dashboard request
+  path never blocks, even on 8000+ session databases where a cold scan
+  takes minutes.
+
+The upstream repo ships its own unittest suite under
+``plugins/hermes-achievements/tests/`` covering the achievement engine
+internals (tier math, secret-state handling, catalog invariants). These
+tests live at the hermes-agent level and focus on the integration
+contract: the plugin scans ALL of your sessions, not the first 200.

+"""Tests for Kanban task file attachments (#35338).
+
+Covers three layers:
+  * ``hermes_cli.kanban_db`` accessors (add/list/get/delete + path helpers)
+  * the dashboard REST surface (upload / list / download / delete)
+  * worker-context surfacing so a kanban worker sees the absolute paths
+
+The plugin router is attached to a bare FastAPI app — same approach as

+(multipart upload, streaming download) without the whole dashboard.

+"""Guardrail: dashboard plugins must NOT read the session token directly.
+
+The dashboard host exposes a sanctioned, gated-mode-aware auth surface on the
+plugin SDK (``window.__HERMES_PLUGIN_SDK__``): ``fetchJSON`` (JSON REST),
+``authedFetch`` (uploads / blob downloads), and ``buildWsUrl`` /
+``buildWsAuthParam`` (WebSockets). These handle BOTH dashboard auth modes —
+loopback (``X-Hermes-Session-Token`` header) and gated OAuth
+(``hermes_session_at`` cookie / single-use ``?ticket=``).
+
+Plugins that hand-roll ``fetch`` / ``WebSocket`` and read
+``window.__HERMES_SESSION_TOKEN__`` directly send an empty token in gated mode
+and 401/1008. That bug shipped in the kanban and achievements plugins and was
+invisible until the dashboard ran gated on hosted Fly agents.
+
+This test fails if any bundled plugin's frontend reads the token global
+directly, forcing new/edited plugins through the SDK surface instead. It is
+the enforcement half of the "single sanctioned auth surface" design — the SDK
+helpers are the carrot, this test is the stick.
+
+If you have a legitimate reason to reference the token name (e.g. a comment
+explaining why NOT to use it), add the file to ``_ALLOWED_FILES`` with a note.

+"""Regression tests: plugin-family credential reads honor the profile secret scope.

+Class-closure follow-up to the profile secret-scope cluster (#76462). Memory,
+image_gen, and browser plugins, plus a handful of tier-3 tool helpers, read
+credentials straight from ``os.environ``. Under a multiplexed gateway the
+process environment may hold ANOTHER profile's key (or none), so every
+credential read must route through ``agent.secret_scope.get_secret`` and honor
+its verdict — a scoped miss under multiplexing returns the default and must
+NOT borrow from ``os.environ``.
+
+One representative test pair (scoped-wins / scoped-miss-no-borrow) per plugin
+family, plus the two behavioral sites:
+
+* supermemory ``post_setup`` must not write a profile's key into the
+  process-global environ when multiplexing is active (sibling-profile
+  pollution).
+* google_meet ``process_manager.start`` must resolve OPENAI_API_KEY through
+  the scope AT SPAWN TIME and pass it explicitly in the child environment —
+  the detached child inherits the process env, not the contextvar scope.

+

+    least one trigger; names are unique.
+  * ``_scan_content`` — true positives (pickle.load, yaml.load, eval,
+    dangerouslySetInnerHTML, GitHub Actions workflow), true negatives
+    (.md skips Python rules, ``model.eval()`` doesn't trip eval),
+    path-only rules (``path_check``), content-only rules
+    (``path_filter``).
+  * Hooks — ``transform_tool_result`` appends a warning block in warn
+    mode and stays out of error results; ``pre_tool_call`` blocks
+    writes when ``SECURITY_GUIDANCE_BLOCK=1`` and stays silent
+    otherwise.
+  * Bundled-plugin discovery via ``PluginManager.discover_and_load``.

+"""GitSpawn / GHSA-7x36-8jrh-v4pw regression suite.

+A repository delivered as files (zip, sync folder, USB) can carry a
+``.git/config`` that names a command in an execution-sink git setting —
+``core.fsmonitor``, ``core.hooksPath`` hooks, or an attribute-scoped
+``[diff "x"] command=/textconv=`` driver. Hermes gathers workspace context by
+running git against the session directory automatically, before any prompt,
+approval, or trust gate, so an unhardened probe would execute that command on
+the host as the user.
+
+These tests build a real malicious repo and assert that every automatic
+context-gathering git path Hermes runs neutralizes every sink. They use a real
+``git`` and skip if it is unavailable.

+"""End-to-end regression for #24015 — capture routing via auxiliary.vision.
+
+When ``computer_use(action='capture', mode='som'|'vision')`` returns a
+screenshot, ``_capture_response`` previously always returned a
+``_multimodal`` envelope. For non-vision main models, or when the user
+explicitly configured ``auxiliary.vision`` in ``config.yaml``, that
+envelope tripped HTTP 404 / 400 at the provider boundary even though a
+perfectly good vision backend was sitting in config waiting to be used.
+
+This file exercises the integrated ``_capture_response`` flow with
+deterministic stubs for:
+
+* ``should_route_capture_to_aux_vision`` (the policy decision)
+* ``_run_async`` (sync->async bridge)
+* ``vision_analyze_tool`` (the aux LLM call)

+"""Regression for the X11 null-PID `list_windows` crash.
+
+On X11 a window's PID comes from the *optional* ``_NET_WM_PID`` property, so
+the cua-driver legitimately reports ``pid: null`` for windows that don't set
+it (the desktop root, panels, override-redirect popups, …). Both
+``capture()`` and ``focus_app()`` previously coerced *every* window's pid via
+``int(w["pid"])`` inside a list comprehension, so a single null-pid window
+raised::
+
+    TypeError: int() argument must be a string, a bytes-like object or a
+    real number, not 'NoneType'
+
+…aborting the whole enumeration before any screenshot was taken — i.e. the
+agent could never capture the screen at all on an X11 desktop that had even
+one such window.
+
+The fix routes both ingestion sites through ``_ingest_windows``, which skips
+windows lacking a usable pid/window_id (uncapturable anyway) and coerces the
+rest, so real targetable windows survive.

+"""delegate_task(action=...) — model-facing live orchestration of subagents.
+
+Covers the control plane added to delegate_task: action='list' /
+'steer' / 'stop' resolve against the module-level _active_subagents
+registry, scoped by the _delegate_parent_ref ownership chain so a
+conversation can only control its own spawn tree. Also pins the two
+integration contracts: control actions are synchronous (never
+backgrounded) and never consume the per-turn subagent spawn cap.

+"""Tests for capability-gated MCP tool discovery and keepalive.
+
+Prompt-only / resource-only MCP servers do not implement the ``tools/*``
+request family. Per the MCP spec, ``InitializeResult.capabilities.tools``
+is non-None iff the server supports it. Before the capability gate, Hermes
+always called ``tools/list`` during discovery, which raised
+``MCPError(-32601 Method not found)`` against such servers, so a prompt-only
+server could never stay connected. Discovery/refresh remain capability-gated.
+
+The keepalive probe uses ``ping`` (MCP base-protocol liveness) for every
+server regardless of capability: it works uniformly and stays a few bytes
+instead of pulling the full ``tools/list`` payload (which is ~1 MB on large
+servers like Unreal Engine's editor MCP). Its cadence is configurable via
+``keepalive_interval`` so servers with short session TTLs stay alive.
+
+Discovery gating ported from anomalyco/opencode#31271.

+"""Tests for MCPServerTask._preflight_content_type fast-fail behaviour.
+
+These drive the REAL ``_preflight_content_type`` method against a real local
+HTTP server (via httpx's ASGI/transport plumbing through a stdlib server),
+rather than reimplementing the probe inline. That distinction matters: the
+production probe must run on its own httpx client outside the MCP SDK's anyio
+task group, and a faithful test must exercise that actual method so the
+content-type allow-list, HEAD->GET fallback, POST probe fallback, and
+best-effort pass-through are all covered as shipped.
+
+OAuth note
+----------
+``MCPServerTask.run()`` skips the preflight entirely when ``auth_type=="oauth"``
+(see ``test_run_skips_preflight_for_oauth``).  OAuth-protected MCP servers
+return ``200 text/html`` (a login/landing page) on an unauthenticated probe,
+which ``_preflight_content_type`` correctly rejects — the probe cannot tell
+whether the page is a valid OAuth endpoint or a misconfigured URL.  The right
+validator for OAuth servers is ``.well-known/oauth-protected-resource``, which
+the OAuth handshake consults automatically.

+The gateway's loopback api_server refuses to start without a strong
+API_SERVER_KEY, and hosted cron fires are forwarded through it — so the
+stage2 keygen must succeed even when no ``.env`` exists yet. Historically it
+was gated on ``[ -f "$HERMES_HOME/.env" ]`` while the first-boot seed that
+was supposed to create ``.env`` silently no-oped (``.env.example`` was
+excluded from the image by ``.dockerignore``), leaving 40%+ of the hosted

+Tests for the STT command-provider registry (``stt.providers.<name>``).
+
+Mirrors ``tests/tools/test_tts_command_providers.py`` — same shape, same
+invariants, adapted for the input=audio → output=transcript flow.
+
+Covers:
+- Resolution: built-in precedence, missing/unknown name, type/command gating
+- Placeholder rendering: shell-quote-aware, doubled-brace preservation
+- Helpers: timeout fallback, output_format validation, iter/has-any
+- End-to-end via transcribe_audio(): command-provider wins when configured,
+  built-ins still win when name collides, plugin coexistence
+
+Nothing here talks to a real STT engine. The shell command writes a static
+transcript to ``{output_path}`` using ``python -c`` so the tests run
+identically on Linux, macOS, and Windows (with minor quoting differences).

+coordinate space. These tests verify that both vision paths now disclose the
+scale factor / crop offset so coordinates can be mapped back deterministically:

+  ``(bytes, scale_note)``;
+* ``tools.vision_tools.vision_analyze_tool`` emits a ``scale_note`` field and

+"""Integration of the verify subsystem with the existing verification stack.

+Covers the closed loop the rescoped PR is about:

+- ``hermes verify`` records into the evidence ledger (pass and fail),
+- a passing run satisfies the verify-on-stop guard,
+- the verify-on-stop nudge names ``hermes verify --json`` when the workspace
+  has a runnable recipe (start command or saved manifest),
+- the CLI's detect path merges ``detect_project_facts`` verify commands the

+
+The index used to be a hand-written list of page paths, and it rotted to 53%

+platforms were all absent, which is why an agent asked how to make bots talk to
