Add policy-bound AG-UI adapter for Mercator acceptance - #8
Conversation
Expose the Hermes AIAgent over the AG-UI protocol via an HTTP/SSE server (FastAPI + uvicorn), mirroring the ACP adapter's provider resolution. - server.py: POST / streams RUN_STARTED/TEXT_MESSAGE_*/TOOL_CALL_*/RUN_FINISHED; live in-order text + server-tool event streaming; internal state-writer tool chips suppressed; open events closed on mid-run failure before RUN_ERROR; DNS-rebind Host guard + JSON-only CSRF middleware. - session.py / translate.py: agent construction, AG-UI<->Hermes message and tool translation, shared-state / reasoning / multimodal / agent-config. - events.py: callback -> AG-UI event bridge. resume_shim.py: resume plumbing. - entry.py / __main__.py: `hermes-agui` console entry (env-driven, loopback default). - pyproject.toml: `[agui]` extra pinned to the CVE-fixed starlette stack + script.

Loopback bind is zero-config (the OS boundary is the authorization); a network-accessible bind refuses to start without a usable HERMES_AGUI_SESSION_TOKEN (>=16 chars, not a placeholder) — an open bind to a terminal-capable agent is RCE. Adds a DNS-rebinding Host guard. Reuses the shared gateway `is_network_accessible` + hermes_cli `has_usable_secret` helpers, matching the API server and dashboard posture.

Map a blocking dangerous-command approval onto AG-UI's native interrupt lifecycle: the worker parks across requests (thread_id-keyed registry), the run ends at the interrupt, and the resume run resolves the decision. Fails closed to deny on timeout/error; neutralizes inherited gateway/ask env flags that would otherwise bypass the interrupt; redacts the gated command in the one server-side audit log (force=True hard secret boundary).

Document the adapter's security model (loopback vs network bind, token, Host/CSRF guards, approval flow) and the one known limitation: write_file/patch edit-approval is not gated on this surface. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
A frontend or state-writer declaration whose name was already owned by a registered server tool was skipped at registration but still merged into `agent.valid_tool_names`, leaving the name callable. `registry.dispatch` resolves purely by name, so a client declaring `terminal`, `write_file`, or `execute_code` as a client-side tool caused the model's call to execute the SERVER tool instead of handing off to the client. Reject the run up front instead of silently degrading it. The check sits below the `run_agent` import in `build_run_agent` because that import is what populates the registry (`model_tools` runs `discover_builtin_tools()` at import time) — hoisting it above would make the check vacuous. Registration is process-global and idempotent while declarations are per-run, so by run two the adapter's own handler occupies the name and a bare "is this name registered?" test would reject every legitimate repeat run. The exemption for the adapter's own toolsets is therefore per-kind: a name may be re-declared only as the same kind it was registered as. A blanket exemption would reintroduce the same shadowing bug one layer in — a state-writer name re-declared as a frontend tool skips registration and stays bound to the state-writer handler while being advertised to the model as client-executed. Declaring one name as both kinds in a single run is rejected as ambiguous. The server surfaces this as a RUN_ERROR naming the offending client tools, without enumerating server tool names back to the client.

`hermes-agui` is registered as a console_script pointing at `agui_adapter.entry:main`, but the module did not import `hermes_bootstrap` first, so UTF-8 stdio setup on Windows and `harden_import_path()` never ran. Mirrors the guarded-import preamble in `acp_adapter/entry.py`. `from __future__ import annotations` is dropped rather than kept: a future statement must precede every other import, which would displace the bootstrap import and make the contract unsatisfiable. It was unnecessary anyway (requires-python is >=3.11, so PEP 604/585 annotations are native), and none of the other six entry points carry one. Adds the file to `TestEntryPointsImportBootstrap.ENTRY_POINTS`, which previously codified the contract for five entry points but not this one — so the suite passed while the contract was violated. `python -m agui_adapter` is covered too: `__main__.py` imports `agui_adapter.entry`, which triggers the bootstrap at module import. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The Tests section claimed the `@copilotkit/aimock` fixture server was "auto-installed" under `tests/agui_adapter/.aimock`. There is no auto-install: `test_e2e_aimock.py` skips with a manual hint when the CLI is absent, so all 10 of its end-to-end cases were silently not running for anyone who had not installed it by hand. Replaces the claim with the install that actually works, plus the two traps behind it. A local `package.json` must exist first or npm walks up and installs into the repo-root `package.json`, leaving `.aimock/` empty and the tests still skipping. And it has to be written by hand — `npm init -y` defaults the package name to the directory name and npm rejects `.aimock` as invalid because it starts with a dot. Also documents, under Security, that server tool names are reserved for client declarations — the behavior added alongside this change, which clients will hit as a RUN_ERROR.

📝 WalkthroughWalkthroughThe PR adds a Hermes AG-UI adapter with request translation, per-run agents, HTTP/SSE streaming, frontend tool handoff, shared state, approval resume flows, authentication, Mercator policy support, packaging, documentation, and tests. ChangesAG-UI adapter
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR adds a network-facing policy-bound adapter, but the current head still accepts client-provided forwarded properties, lacks explicit Host/content-type protections, and documents bearer-token paths that can expose credentials while not satisfying the stated caller-allowlist requirement. These security-boundary gaps could enable unintended handler exposure or credential leakage, so the PR should not merge until security owners resolve them. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@agui_adapter/README.md`:
- Line 172: In the README sentence near the hermes-agui reference, replace
“serve interface” with “serving interface” and use “actual” as specified, so it
reads “pass the actual serving interface.”
In `@agui_adapter/resume_shim.py`:
- Around line 41-84: Update resume handling in the conversation loop’s synthetic
user-message append path instead of wrapping the nonexistent build_turn_context
symbol. Remove or bypass the unavailable-symbol fallback in install(), and when
resuming after a trailing tool message, remove the synthetic user message,
recompute the latest user-message index, assign current_turn_user_idx, and
update agent._persist_user_message_idx.
In `@agui_adapter/server.py`:
- Around line 700-722: Update create_mercator_acceptance_app so the returned
application applies the same Host/DNS-rebinding and JSON content-type
protections provided by create_app’s _security middleware, or explicitly
document and enforce that the outer ASGI layer owns both guards; preserve
Mercator authentication as the outer-layer responsibility.
- Around line 432-438: Ensure the tool-registry refresh path preserves
AgentConfig.frontend_only: after HERMES_KANBAN_TASK or other refresh logic
repopulates tools, reapply the frontend-only filter so server tools cannot be
restored after build_run_agent clears agent.tools, or reject this environment
before refresh.
In `@agui_adapter/session.py`:
- Around line 270-328: Prevent process-global accumulation of client-declared
tools in _ensure_frontend_tools_registered and
_ensure_state_writer_tools_registered by removing adapter-owned registrations
when their run ends, or by enforcing a bounded per-run limit on accepted names.
Preserve real backend tools and ensure removed names are no longer dispatchable
to later runs.
- Around line 439-484: Close the check-then-register race in the agent setup
flow around _reject_name_collisions, _ensure_frontend_tools_registered, and
_ensure_state_writer_tools_registered by holding _reg_lock across the collision
check and both registrations, or by revalidating each toolset owner inside the
locked registration path and raising ToolNameCollisionError on conflicts. Ensure
concurrent runs cannot advertise a name whose registry owner differs from the
registered handler.
- Around line 230-240: Update the exception logging in _frontend_tool_handler so
agent.interrupt() failures use warning level instead of debug, while preserving
the existing placeholder return and exception-info details.
In `@agui_adapter/translate.py`:
- Around line 204-215: Update prepare_run to handle an empty messages list
before evaluating the resume branch, returning a PreparedRun with
is_resume=False and an empty user_message. Preserve the existing user-turn and
resume behavior for non-empty message lists.
- Around line 58-71: Update _image_url_from_source to read the data source MIME
type from both snake_case mime_type and camelCase mimeType, preserving the
existing image/png fallback when neither is present.
In `@pyproject.toml`:
- Line 115: Update the agui dependency specifications to use bounded version
ranges for ag-ui-protocol, fastapi, and uvicorn, retaining the listed versions
as minimums and adding compatible upper bounds that exclude vulnerable releases.
In `@SECURITY.md`:
- Around line 183-185: Update the AG-UI network authorization policy and
implementation consistently: either add an operator-configured caller allowlist
for every enabled AG-UI HTTP/SSE endpoint, enforcing it fail-closed at startup,
or document explicit security approval for the existing session-token and
loopback OS-boundary model while preserving fail-closed startup behavior. Anchor
changes to the AG-UI policy text and the agui_adapter authorization/startup
configuration symbols.

preserving the existing “core tools” message check.
- Around line 108-163: Add a denied-authorization test alongside
test_worker_context_and_every_frontend_handoff_reach_policy that configures
policy_store.authorize to raise PermissionError, runs _event_stream with the
shared fake turn setup, and asserts no TOOL_CALL_START frame is emitted while a
RUN_ERROR frame is produced. Extract fake_turn to module scope so both tests can
reuse it.
In `@tests/agui_adapter/test_resume_shim.py`:
- Around line 21-43: Add a test for the missing-build_turn_context branch of

monkeypatch.delattr, call install(), and assert it does not raise and does not
install a wrapper. Keep the test isolated from the existing installed-state
guard and verify the attribute remains absent.
In `@tests/agui_adapter/test_translate.py`:
- Around line 240-243: Update the test around
test_run_state_no_arg_merges_args_dict_into_key to use a StateWriterSpec with
arg=None, exercising whole-args merging through RunState.apply. Cover the empty
state_key case as a top-level merge so the spec.arg is None branch is tested,
while retaining the existing assertion for merged state values.

The `agui` extra was declared and locked, but never added to the `[all]` aggregate that CI and packagers install. `uv pip install -e ".[all,dev]"` resolved without `ag-ui-protocol`, so every `agui_adapter` import failed: four tests in `test_approvals.py` failed and five more modules (`test_auth`, `test_events`, `test_translate`, `test_mercator_policy`, `test_e2e_aimock`) errored during collection. This passed locally because a hand-installed `.[agui]` left `ag_ui` in the working venv, so the gap only ever showed up in a clean resolution. Fixing the workflow instead would have turned CI green while leaving the published wheel broken — `hermes-agui` is a declared console script, so it would still raise ModuleNotFoundError for anyone installing normally. This is the same failure the `youtube` extra documents. `acp`, the sibling protocol adapter, was already in `[all]`; `agui` now matches it. `fastapi` and `uvicorn` already reach `[all]` through `[web]`, so the lockfile grows by one pure-Python wheel and no versions move. Adds a packaging test asserting both adapter extras stay reachable from `[all]`, since the failure is invisible to anyone with a warm venv.

Three defects from the CodeRabbit pass, all in the AG-UI translation and session layer. `_block_field` read only the snake_case pydantic field name, so a raw AG-UI JSON block carrying `mimeType` fell through to the `image/png` default and every non-PNG data source was mislabelled. The existing test could not catch this: it passes `mimeType: "image/png"`, which is also the fallback value, so it succeeded whether or not the key was ever read. The new test uses `image/jpeg` so it fails without the fix. `prepare_run` derived `last_role` as None for an empty message list and fell into the resume branch, arming the resume shim for a run with no tool result and no user turn to strip. Empty input is now an ordinary non-resume run. A failed `agent.interrupt()` in the frontend tool handler was logged at debug. The run then continues, the model reads the placeholder as a real tool result, and the client never receives the handoff — a broken run, so it now logs at warning. Also corrects "serve interface" to "serving interface" in the README. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Three findings on the client-declared tool registry, all from the CodeRabbit pass on the policy-bound adapter. The collision check read the registry outside `_reg_lock` while registration wrote it inside, so two concurrent runs could both pass the check for a name neither had registered yet. The loser then advertised that name in `valid_tool_names` while the registry had it bound to the winner's handler — the shadowing this module exists to prevent, one layer in. The registry read now happens under `_reg_lock`, and `build_run_agent` holds that lock across the check and both registration helpers, so the sequence is atomic. `_reg_lock` becomes an RLock because the helpers each acquire it when called on their own. The pre-existing check before agent construction is kept as the fail-fast path — the tests pin that a collision is rejected before any name can become callable — with the authoritative check repeated under the lock. A check released before the write cannot exclude a concurrent run. Adapter-owned registrations are never evicted, because a name may be bound to an in-flight run's handler at any moment and eviction would need run-level refcounting. They are now capped instead, so a client inventing a fresh name per request cannot grow the process registry without limit. The cap is far above any legitimate client and the policy-bound Mercator surface never grows at all, serving a fixed schema list. `frontend_only` promised an empty server-tool surface but only cleared `agent.tools` at construction. `_compute_tool_definitions` appends the kanban toolset whenever HERMES_KANBAN_TASK is set, even for `enabled_toolsets=[]`, so any later refresh handed back the server tools that were just removed. The two configurations are contradictory, so the combination is now refused up front rather than relying on nothing triggering a refresh. The atomicity test was confirmed to fail with the lock removed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Five findings from the full review of ae768e8. - auth: accept `?token=` only on a loopback bind. A query token leaks into browser history, Referer headers and reverse-proxy access logs, none of which this process controls; uvicorn's own access log being suppressed at `warning` says nothing about a proxy in front. The header carrier still works on every bind and no known AG-UI client needs the query form. - session: stop reporting "State updated." when `run_state.apply()` raises. The model was told the write succeeded while shared state was unchanged and no StateSnapshotEvent was emitted. Return an error result and log at `warning` instead of `debug`. - approval/cronjob/terminal: route the interactive check through the new public `is_interactive_cli()` resolver. `cronjob_tools` and `terminal_tool` read `HERMES_INTERACTIVE` directly, so an AG-UI run with the interactive ContextVar set but the env var unset skipped cronjob availability and sudo prompting. - tests: `test_run_state_no_arg_merges_args_dict_into_key` passed `arg=`, which exercises the spec.arg path another test already covers; the arg-is-None merge path was untested. Drop the arg and assert the merged dict. - README: label the two unlabelled fenced blocks (markdownlint MD040). Adds regression coverage for the non-loopback query-token rejection and for both state-writer outcomes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`tests/tools/test_managed_browserbase_and_modal.py` replaces `tools.approval` with a SimpleNamespace exposing a fixed name list, so terminal_tool's new module-level `is_interactive_cli` import raised ImportError at collection and failed four tests in CI. The stub is a narrow fake of a real module; adding the name it now needs keeps the fake honest, rather than moving the production import inside the function to dodge the stub. These tests exercise backend selection, not sudo, so a non-interactive answer keeps the prompt path inert. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Round 5 findings from the CodeRabbit review of fe8e880. - The policy-bound endpoint rejected body["tools"] and replaced it with the contract's schemas, but left forwardedProps untouched. _run_turn feeds forwarded_props to translate.parse_state_writer_props (server.py:170) and build_run_agent then registers a SERVER-EXECUTED handler for every name declared there. So a client could still grow the advertised surface past contract.frontend_tool_schemas(), contradicting both the factory docstring and the server_tool_names/server_toolsets emptiness checks, and consuming process-global adapter registry capacity on the one surface designed to be fixed and growth-free. Both the camelCase and snake_case spellings are now refused; unrelated forwardedProps still pass. - The acceptance resume rejection emitted RunErrorEvent without a preceding RunStartedEvent, unlike every other terminal path in this generator, so a client correlating by run lifecycle got an error for a run it never saw start. - The test conftest cleared approvals._parked without resolving PendingApproval.decision, leaving a worker thread parked by a failed test blocked on a future nobody would complete until the approval timeout. It now denies each pending decision first, matching the timeout path's fail-closed behaviour. NOT fixed here, filed instead: the nested-terminal approval bypass (code_execution_tool.py starts its RPC threads without copy_context, so the interactive ContextVar does not reach them and check_all_command_guards takes the non-interactive allow branch). It is real, but it predates this branch, it is a Hermes-core change rather than an adapter one, and it is unreachable on the policy-bound acceptance surface, which enforces zero server tools. Verified: 131 agui_adapter tests pass, ruff clean, and a full parallel run shows no failing file outside the known pre-existing set (the three that differed all pass in isolation).

test_policy_bound_factory_requires_zero_server_and_core_tools set only allow_core_tools, despite naming server tools in its own title. The server_toolsets and server_tool_names branches it was named for never ran, and neither did the policy_api_version, use_hermes_approvals, allow_inherited_approval_state, or empty-schema rejections -- six fail-closed gates on the policy-bound surface, one exercised. Replaced with a parametrized case per gate plus a frontend-schema test covering empty, non-list and None. Verified the coverage is real: removing the server-tools gate fails exactly the two parametrized cases that cover it and nothing else.

The conftest helper added in 4643a4a read approvals._parked and called clear() directly, while register(), take() and discard() all hold approvals._lock. A registration landing concurrently could therefore be dropped from the registry without its decision ever being resolved, leaving that worker blocked until the approval timeout -- the exact failure the helper was written to prevent. Moved the cleanup into the module that owns the lock: approvals.release_all() drains the registry and resolves every pending decision under _lock, so a concurrent registration is either fully drained or not drained at all. Defaults to "deny", matching the fail-closed timeout path. The conftest fixture now calls it instead of reaching past the lock. Covered by test_release_all_resolves_pending_decisions_and_drains: registers a parked run, asserts release_all() reports 1, the future resolves to "deny", the entry is gone, and a second call on an empty registry is a no-op.

The README told clients to resume with `resume:[...]` after an interrupt while, 105 lines later, stating resume is disabled on the current Verdigris fork pin. Same document, contradictory instructions — a client following the first paragraph would send a continuation the pinned runtime cannot service. My earlier fix corrected the Resume bullet without grepping for other references, which is how this survived. Now cross-referenced in both directions.

…inds Round 1 of this review restricted `?token=` to loopback binds in agui_adapter/auth.py. The README was not updated with it, so the security section still told clients they could send the token as a query parameter on a network bind. That is not merely risky advice — it is now false. `token_valid` returns False for a query token whenever `is_network_accessible(bound_host)`, so a client following the README would simply be refused. Second documentation drift from my own fix in this PR, after the resume paragraph. Same cause both times: I corrected behaviour without grepping for the prose that described it. Grepped `token=` across the README and SECURITY.md; this was the only remaining occurrence. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

… gate The gstack pre-landing review had never been run on this PR. It was run tonight with three specialists. Two defects and a set of untested enforcement paths came out; this commit takes the unambiguous ones. Defects: - session.py state-writer handler returned "State updated." when _CURRENT_STATE.get() is None. Any thread that never inherited the run context — a subagent or delegate worker — reads None there, so the model was told the write succeeded when no state object existed at all. This is the same silent-success shape I fixed for the exception branch in an earlier round and did not carry across to the None branch three lines above it. Both paths now log and return an error result. - server.py version gate used `!= MERCATOR_ACCEPTANCE_POLICY_API`. bool subclasses int and True == 1, so True and 1.0 both satisfied the only version check protecting a SHA-pinned consumer in another repository. Now `type(v) is not int or v != ...` — `type(...) is not int` rather than isinstance, because isinstance would still admit True. Enforcement that was correct but had never executed in any test: - server.py the cross-run guard `thread_id != principal.run_id`. Verified by removing it: exactly the new test fails, nothing else. - server.py the `principal is None` fail-closed gate. - server.py the resume refusal on a policy-bound app, which otherwise falls through to approvals.take() and re-attaches a terminal-capable worker. - session.py `frontend_only` clearing agent.tools and valid_tool_names. This is the load-bearing line behind the entire zero-server-tools claim, and no test had ever run it. Now asserted both ways: the surface advertises exactly the frontend schemas, and terminal/execute_code/write_file/patch/ delegate_task are all absent from valid_tool_names. Also corrected a vacuous test I added earlier in this PR. test_policy_bound_factory_allows_unrelated_forwarded_props asserted only status 200, but a policy-bound stream returns 200 as soon as it starts streaming — the body of that very response is a RUN_ERROR. It asserts contract.started now, which is what actually proves the props cleared every gate. agui_adapter coverage 79% -> 83%; session.py 56% -> 70%. 147 pass, ruff clean. Not addressed here, and left for review rather than changed overnight: the worker->loop SSE queue is unbounded, each accepted POST spawns an uncapped daemon thread, and frontend_tool_schemas carries a different shape across the repo boundary than the same parameter name means inside this package. Those are design calls on a network-facing surface, not cleanups. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…r sudo Self-inflicted, and worse than the bug it replaced. My earlier fix in this PR gated the sudo prompt on `is_interactive_cli() and (callback or sys.stdin.isatty())`. The isatty fallback is the problem. hermes-agui is normally started by uvicorn in a foreground terminal, so stdin IS a tty — it just belongs to the operator, not to the remote client issuing the command. An AG-UI run sets the interactive ContextVar, no sudo callback is ever registered on that path (only cli.py registers one), so the gate returned True and `_prompt_for_sudo_password()` opened the operator's /dev/tty, disabled echo, and asked for a root password on behalf of a stranger. Any password typed is cached and used to run the remote command as root. Nothing gates it first: plain `sudo cmd` is deliberately excluded from the dangerous-command patterns (tools/approval.py) precisely BECAUSE it is TTY-bound and the agent was assumed not to have one. My change invalidated that assumption without updating it. My own test only asserted the isatty() -> False case, which is not the deployed one. The fix distinguishes where the interactive signal came from. tools/approval.interactive_signal_source() reports "context" (an adapter set the run-scoped ContextVar, so the caller is remote) or "env" (a human set HERMES_INTERACTIVE, so the caller is at this terminal). A raw tty now qualifies only for "env". A registered callback still qualifies, because only the CLI and TUI register one and it prompts the person who typed the command. An explicit non-interactive signal suppresses everything, checked first — an existing test caught me loosening that. Verified both directions: restoring the gate I shipped fails exactly the new test and nothing else. Found by the gstack security specialist, which had never been run on this PR.

Adding `interactive_signal_source` to terminal_tool's module-scope import broke collection of test_managed_browserbase_and_modal.py, which replaces tools.approval with a fixed-name SimpleNamespace. Four tests failed with an ImportError that names no file in the change. Second time this stub has gone stale for the same reason, so the comment now states the coupling: it must carry every name terminal_tool imports from tools.approval. Returns None, meaning no interactive signal, which matches is_interactive_cli returning False. These tests exercise backend selection, not sudo.

Three unbounded things, all decided by Thomas. The approval label. Every run was labelled with the thread_id the caller sent, and tools.approval keys its skip-prompts set on that string, process-wide. A caller who sent thread_id="ops" shared a label with a person who typed /yolo in a session called "ops", and inherited their bypass. Nothing checked the label. Today the adapter runs alone in its own process so that set is always empty, but that safety is a deployment rule nobody wrote down. The label is now prefixed "agui:", which makes the collision impossible rather than unlikely. Set in one place, and the same worker spans park -> resume, so an approval granted during a run is still found after a resume. The event queue. Unbounded, so an SSE reader that went away left the worker producing into a queue nobody drained until the process died with no log line explaining it. Now capped at 1000 events. What matters is the overflow path: dropping events silently would hand the client a partial transcript it believes is whole, which is the one thing a service producing audit evidence must not do. Overflow interrupts the run and ends the stream with RUN_ERROR saying the record is incomplete, never RUN_FINISHED success. The run count. One OS thread per POST, uncapped, so a retry storm exhausted the process. Now 8 concurrent runs; over that the adapter answers "at capacity" and the client retries. The slot is held from before the thread starts until the worker genuinely finishes, which includes the whole park -> resume arc because a parked run still owns its thread. If the thread fails to start the slot is released rather than leaked, which would otherwise refuse every run forever. Both caps read HERMES_AGUI_MAX_QUEUE_EVENTS and HERMES_AGUI_MAX_CONCURRENT_RUNS. The defaults are judgement, not measurement: 1000 is far above any real run and far below memory pressure; 8 suits single-digit reviewers. Revise them against real load. A bad value warns and falls back instead of crashing. Verified against the full suite twice, 29 minutes each. The failure sets before and after are identical (110 = 110, zero new), and the passed count rises by exactly the 10 tests added here. Those 110 are this machine missing optional dependencies; CI runs the same suite at 24913 passed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
