1262fd79e3 test(copilot/sdk-compat): carry forward socket/strict-assert fixes from #12741
After rebasing onto the updated chore/sdk-cli-compat-tests base, re-apply
the three improvements that were already committed on #12741 but got
shadowed by this PR's own CodeRabbit follow-up commit on the same file:

- Replace `site._server` private aiohttp access with the public socket
  API (bind an ephemeral port via `socket.bind` + `web.SockSite`).
- Convert the catch-all 404 route from a bare lambda to
  `async def fallback_handler` to silence the aiohttp deprecation warning.
- Tighten `test_returns_none_when_env_var_points_to_missing_file` to
  `assert resolved is None` so the strict fail-loud semantics of the
  override path are actually enforced.

The JSON-walker and `proc.communicate()` reap this PR already had are
strictly better than the regex / `proc.wait()` versions on #12741, so
those are kept as-is from the CodeRabbit follow-up commit.

c64d7f934c fix(copilot/sdk-proxy): abort transport on mid-stream upstream error
The previous fix set a ``stream_error`` flag and returned the
prepared ``StreamResponse`` without calling ``write_eof()``,
assuming aiohttp would leave the body dangling. It doesn't:
aiohttp's handler dispatcher finalises any returned
``StreamResponse`` on the way out (writing the chunked terminator /
content-length / EOF), so a regression test with a real mid-stream
failure still saw the client get a clean 200 body.

Correct fix: on the stream-error path, abort the underlying
transport directly via ``request.transport.abort()`` and then
re-raise the original stream error out of the handler. Aborting
drops the TCP socket mid-response so the client's parser surfaces
a ``ClientPayloadError`` / ``ServerDisconnectedError`` and the
caller sees the truncation as a real transport failure.

Also rewrote the regression test to use a raw
``asyncio.start_server`` TCP handler that sends a chunked response
header plus one partial chunk and then hard-closes the socket
(``transport.abort()``) — this is the one failure mode that
reliably propagates through aiohttp's ``iter_any()`` as a
``ClientError`` for the proxy to detect.  Verified locally: the
test now fails with the expected ``ClientPayloadError`` on the
client side instead of silently returning 200.

58bcf82d28 fix(copilot/sdk-proxy): treat empty sdk_env ANTHROPIC_BASE_URL as opt-out
Claude Code subscription mode intentionally sets
``sdk_env['ANTHROPIC_BASE_URL'] = ""`` to disable any base-URL
override and keep the CLI talking to Anthropic directly. The
previous ``or``-chained lookup evaluated the empty string as falsy
and fell through to ``os.environ.get("ANTHROPIC_BASE_URL")`` and
then to ``OPENROUTER_BASE_URL``, silently starting the compat proxy
for a session that had explicitly opted out — which breaks
subscription auth.

Use a presence check on ``sdk_env`` instead: if the key is present
with an empty value it's a hard "no-proxy" signal, so skip the
OpenRouter fallback even when ``openrouter_active`` is True. The
process-env fallback and the OpenRouter fallback still cover the
original cases (no sdk_env override, OpenRouter is the routing
provider for this session).

Flagged by sentry review on #12745 (thread 3067906804).

090b1c6734 fix(copilot/sdk-proxy): don't signal clean EOF on mid-stream error
When an ``aiohttp.ClientError`` fires mid-stream the previous code
logged it and then called ``downstream.write_eof()``, which tells
the downstream client "stream complete" on top of a partial,
truncated body. Clients then silently consumed the corrupt response
as if it were a clean success.

Track the stream error in a local variable and, when it's set, skip
the ``write_eof`` call and ``force_close`` the downstream response
so aiohttp drops the connection mid-body. The client's parser then
raises a ``ClientPayloadError`` / ``ServerDisconnectedError`` and
the failure is surfaced instead of silently producing garbage.

Added a regression test that spins up an upstream which calls
``force_close`` mid-response; the proxy must propagate the failure
to the client (exception on ``resp.read()``), never return a clean
body.

Flagged by sentry review on #12745 (thread 3067897364).

e9313fe060 fix(copilot/sdk-proxy): address CodeRabbit follow-ups
Three follow-up findings from CodeRabbit's second-pass review:

* The forbidden-pattern scanner in ``cli_openrouter_compat_test``
  relied on a substring match against the prettified form
  `"type": "tool_reference"` (with a space). The CLI is free to
  emit compact JSON like `{"type":"tool_reference"}` which would
  slip past the scanner and false-pass the reproduction test.
  Replaced the substring check with a JSON walker that catches any
  dict with `type == "tool_reference"` regardless of serialisation,
  with a whitespace-tolerant regex fallback for malformed bodies.
  Added two regression tests (compact form, malformed fallback).

* The timeout path in ``_run_cli_against_fake_server`` called
  ``proc.kill()`` and returned immediately, leaving an unreaped
  subprocess until event-loop shutdown. Reap it with a 5-second
  bounded ``proc.communicate()`` wait after the kill.

* ``test_proxy_returns_502_on_upstream_failure`` swallowed
  ``aiohttp.ClientError`` / ``asyncio.TimeoutError`` on the outer
  ``client.post``. That outer call talks to the *proxy* on
  localhost — not the dead upstream — so any exception there
  indicates a proxy crash and must fail the test, not be caught.
  Removed the except block and bumped the client timeout to 10s to
  give the proxy room to return its 502. Also asserts the response
  body contains the generic "upstream error" text so a regression
  that replaces the 502 with a different status is caught.

55eb2891da fix(copilot): handle bool default in compat-proxy env validator
The ``get_claude_agent_use_compat_proxy`` validator added in the
previous commit used ``if v is None`` to decide when to fall back to
the unprefixed env var. But unlike ``claude_agent_cli_path`` (which
defaults to ``None``), this field has ``default=False``. Pydantic-
settings passes the default bool into a ``mode="before"`` validator
when no explicit value is provided, so the ``is None`` branch never
fired and the unprefixed ``CLAUDE_AGENT_USE_COMPAT_PROXY`` env var
was silently ignored.

Switch to checking the raw process env directly: if the prefixed
``CHAT_CLAUDE_AGENT_USE_COMPAT_PROXY`` is set we trust Pydantic's
parsed value (which preserves any explicit ``false``), otherwise we
return the unprefixed env var's raw string so Pydantic's usual
truthy/falsy coercion handles it.

Added a new ``TestClaudeAgentUseCompatProxyEnvFallback`` class
covering both env-var names, the prefixed-wins-over-unprefixed
precedence (including the ``CHAT_...=false`` + unprefixed ``=true``
case), and the default. Also added the mirror tests for
``claude_agent_cli_path`` and included the new env var names in the
``_ENV_VARS_TO_CLEAR`` fixture so existing tests don't leak.

Flagged by sentry review on #12745 (thread 3067888297).

7ff794a6e3 fix(copilot/sdk-proxy): address PR review — RFC 7230 hop-by-hop,
timeouts, cancellation, provider gating

Addresses all seven review threads on #12745 (coderabbit + sentry)
in a single commit because they overlap in the same file cluster:

config.py
---------
* ``claude_agent_use_compat_proxy`` gains a ``field_validator`` that
  reads the unprefixed ``CLAUDE_AGENT_USE_COMPAT_PROXY`` in addition
  to the Pydantic-prefixed ``CHAT_`` form, matching the same dual-name
  pattern already used by ``api_key`` / ``base_url`` /
  ``claude_agent_cli_path`` and keeping parity with the docstring and
  the PR description. Without this the operator-facing env var was
  silently ignored because of ``env_prefix = "CHAT_"``.

openrouter_compat_proxy.py
--------------------------
* ``_HOP_BY_HOP_HEADERS`` now includes the canonical ``trailer``
  (singular per RFC 7230 §4.4) alongside the plural ``trailers``;
  ``clean_request_headers`` additionally drops every header whose
  name is listed in the incoming ``Connection`` field value (§6.1
  extension hop-by-hop headers), case-insensitively — previously
  extension hop-by-hop headers could leak upstream.

* ``strip_tool_reference_blocks`` now *removes* dict-valued
  ``tool_reference`` children from their parent dict instead of
  rewriting them to ``null``; the stated "strip anywhere" semantics
  were broken on nested dict assignments and still produced
  schema-invalid payloads upstream. Genuine ``None`` children on
  non-dict values are still preserved.

* ``_handle`` upstream-call error handler now catches
  ``asyncio.TimeoutError`` alongside ``aiohttp.ClientError`` —
  ``aiohttp.ClientTimeout`` raises ``asyncio.TimeoutError`` (not
  ``aiohttp.ClientError``), so hung upstreams used to escape as a
  generic 500 instead of the documented 502.

* Streaming-response handler no longer suppresses
  ``asyncio.CancelledError``. It's now split into its own except
  branch, releases the upstream body, and re-raises so cooperative
  task cancellation works as intended (cancellation while mid-stream
  was previously being caught alongside ``ClientError`` and silently
  swallowed, leading to hung request handlers on client disconnects
  / shutdowns).

* ``start()`` wraps the ``runner.setup() / site.start()`` sequence in
  try/except that tears down both the client session and the
  (partially-initialised) runner on any exception, so failed startups
  never leak resources. The attributes are only published to the
  instance after the full chain succeeds.

service.py
----------
* The compat-proxy startup is now gated on there actually being an
  Anthropic-compatible upstream to forward to. Previously the code
  fell back to ``OPENROUTER_BASE_URL`` unconditionally, which would
  silently re-route direct-Anthropic / Claude Code subscription
  sessions through OpenRouter and break auth. The new gate is:
  explicit ``ANTHROPIC_BASE_URL`` in ``sdk_env`` or the process env,
  OR ``ChatConfig.openrouter_active`` (OpenRouter is configured as
  the session's routing provider). When neither holds we log a
  warning and skip proxy startup — the feature is opt-in and named
  "OpenRouter compatibility", so no-oping direct-Anthropic sessions
  is the safe default. The success log line also drops the upstream
  URL to match the taint-analysis guidance already applied to
  ``openrouter_compat_proxy.start``.

Tests
-----
* Added regression tests for the dict-valued tool_reference fix, the
  Connection-listed header stripping (with case-insensitive matching),
  and an end-to-end 502-on-upstream-timeout test (fake upstream that
  sleeps longer than the proxy's request timeout). The hop-by-hop
  completeness test now also pins ``trailer`` / ``trailers``.

7645882480 fix(copilot/sdk-proxy): drop upstream from log message entirely
Previous fix logged the parsed netloc instead of the full URL, but
CodeQL's `py/clear-text-logging-sensitive-data` taint analysis still
traces the value through `urlparse(target_base_url).netloc` and
flags the log call. Address by dropping the upstream component from
the log entirely — only the local bind port is logged. The upstream
endpoint is discoverable from `ChatConfig` and exposed via the
`target_base_url` property for callers that need it.

550a648307 fix(copilot/sdk-proxy): address CodeQL findings + isort drift
CodeQL flagged two issues in the new compat proxy:

1. `py/clear-text-logging-sensitive-data` (high) — logging
   `self._target_base_url` could leak credentials if a future caller
   passed a URL containing them. Switched to logging only the host
   component (and the local 127.0.0.1 port) so even an
   accidentally-credentialled base URL stays out of logs.

2. `py/stack-trace-exposure` (medium) — returning the upstream
   exception text in the 502 response body could leak internal
   hostnames or stack frames to the client. Changed to a generic
   "upstream error" string; the detailed exception is still logged
   server-side.

Also fixes an isort sorting drift in the test file (private
underscore-prefixed names must sort before public names — local
isort accepted the order, CI's isort did not).

9ae83c5d2f feat(copilot): in-process OpenRouter compat proxy for newer Claude SDK
The Claude Code CLI in any `claude-agent-sdk` version above 0.1.47
sends the `context-management-2025-06-27` beta header / body field
that OpenRouter rejects with HTTP 400. This blocks us from upgrading
to take features we want (`exclude_dynamic_sections` cross-user prompt
caching in 0.1.57, `AssistantMessage.usage` per-turn token tracking
in 0.1.49, the MCP large-tool-result truncation fix in 0.1.55, etc).
Tracked upstream at anthropics/claude-agent-sdk-python#789, no fix
released yet.

This commit adds an in-process HTTP middleware that lets the latest
SDK / CLI talk to OpenRouter unchanged. The proxy:

* listens on `127.0.0.1:RANDOM_PORT`,
* receives every CLI request that would normally go to
  `ANTHROPIC_BASE_URL`,
* strips `tool_reference` content blocks (the original 0.1.46+
  regression — defensive, in case the CLI 2.1.70 proxy detection
  ever regresses) and `context-management-2025-06-27` from both the
  request body's `betas` array and the `anthropic-beta` header,
* forwards the cleaned request upstream and streams the response
  back unchanged.

Wired via `ChatConfig.claude_agent_use_compat_proxy` (default
`False`, opt-in). When the flag is on, the SDK service starts a
proxy per session, injects its local URL into the spawned CLI
subprocess `env` as `ANTHROPIC_BASE_URL`, and tears it down in the
session's `finally` block.

The proxy is intentionally orthogonal to the existing
`claude_agent_cli_path` override:

* `cli_path`  picks **which** CLI binary we run.
* compat proxy rewrites **whatever the chosen binary sends**.

Both can be combined or used independently.

Tests cover:

* the pure stripping helpers (`strip_tool_reference_blocks`,
  `strip_forbidden_betas_from_body`,
  `strip_forbidden_anthropic_beta_header`,
  `clean_request_body_bytes`, `clean_request_headers`) including
  edge cases like empty input, non-JSON bodies, and the
  hop-by-hop header set,
* end-to-end behaviour against a fake upstream server: stripping
  the `tool_reference` block in nested `tool_result.content`,
  rewriting the `anthropic-beta` header,
  removing the forbidden token from the body `betas` array,
  passing through clean requests unchanged, and returning a clear
  502 on upstream failure (no infinite hang).

6dc0b6cffd test(copilot/sdk-compat): tighten reproduction test (regex scan, proc reap, strict assertions, public socket API)
Address self-review findings on cli_openrouter_compat_test.py:

- Switch the tool_reference detection to a whitespace-tolerant regex
  (`"type"\s*:\s*"tool_reference"`). The Claude Code CLI is Node.js
  and `JSON.stringify` without an indent emits no whitespace, producing
  `{"type":"tool_reference"}`. The previous literal substring with one
  spacing would silently miss the real regression.

- Reap the subprocess after `proc.kill()` on timeout via
  `await asyncio.wait_for(proc.wait(), timeout=5)` so we don't leak a
  zombie + open pipe FDs across CI runs.

- Tighten `test_returns_none_when_env_var_points_to_missing_file` to
  assert `resolved is None` exactly. The previous
  `is None or .is_file()` was too permissive — it would also accept
  the function silently falling through to the bundled binary, which
  would defeat the explicit-override semantics.

- Replace `site._server` private aiohttp access with the public socket
  API: bind an ephemeral port via `socket.bind` and pass it to
  `web.SockSite`. Reading the port back via `getsockname` is robust to
  aiohttp internal changes.

- Convert the catch-all 404 route handler from a bare lambda to an
  `async def fallback_handler` to silence the aiohttp deprecation
  warning ("Bare functions are deprecated, use async ones").

a6e306d28a fix(copilot): accept unprefixed CLAUDE_AGENT_CLI_PATH in config
The new `claude_agent_cli_path` field inherited the `CHAT_` Pydantic
prefix from `ChatConfig`, so the documented `CLAUDE_AGENT_CLI_PATH`
env var was silently ignored — operators following the PR description
or the field docstring would set the unprefixed form and the config
would fall back to the bundled CLI.

Add a `field_validator` that reads `CHAT_CLAUDE_AGENT_CLI_PATH` first
and falls back to the unprefixed `CLAUDE_AGENT_CLI_PATH`, matching the
same pattern already used by `api_key` and `base_url`. The test helper
`_resolve_cli_path` in `cli_openrouter_compat_test.py` mirrors the
same two-name lookup so the reproduction test picks up the override
regardless of which form is set, and a new test covers the prefixed
variant explicitly.

Flagged by sentry review on #12741 (thread IDs 3067725580 and
3067768817) as two instances of the same bug.

d6f0fcb052 test(copilot/sdk-compat): unit-test the forbidden-pattern scanner
Add direct unit tests for `_scan_request_for_forbidden_patterns` and
`_resolve_cli_path` so the helper logic stays exercised even on CI
runs where the slow end-to-end CLI subprocess test can't capture a
request (sandboxed runner, missing CLI binary, etc).

Brings codecov/patch coverage above the 80% gate. No production
code changes — tests only.

fdb3590693 chore(copilot): add SDK CLI override + OpenRouter compat regression tests
We've been pinned at `claude-agent-sdk==0.1.45` (bundled CLI 2.1.63)
since PR #12294 because every version above introduces a 400 against
OpenRouter. There are two stacked regressions today:

1. CLI 2.1.69 (= SDK 0.1.46) added a `tool_reference` content block in
   `tool_result.content` that OpenRouter's stricter Zod validation
   rejects. CLI 2.1.70 added a proxy-detection workaround but our
   subsequent attempts at 0.1.55 and 0.1.56 still failed.
2. A newer regression — the `context-management-2025-06-27` beta
   header — appears in some CLI version after 2.1.91. Tracked upstream
   at anthropics/claude-agent-sdk-python#789, still open with no fix.

This commit doesn't actually upgrade the SDK — it adds the
infrastructure we need to upgrade safely *when* upstream lands a fix
or when we identify a known-good newer CLI version via bisection:

* `ChatConfig.claude_agent_cli_path` (env: `CLAUDE_AGENT_CLI_PATH`)
  threads through to `ClaudeAgentOptions(cli_path=...)` so we can
  decouple the Python SDK API surface from the CLI binary version.
  `_prewarm_cli` in the CoPilotExecutor honours the same override.

* `test_bundled_cli_version_is_known_good_against_openrouter` pins
  the bundled CLI to a known-good set (`{"2.1.63"}` today). Any
  `claude-agent-sdk` bump that changes the bundled CLI will fail this
  test loudly with a pointer to PR #12294 and issue #789, instead of
  silently re-breaking production.

* `test_sdk_exposes_cli_path_option` is a forward-compat sentinel that
  fails fast if upstream removes the `cli_path` option we depend on
  for the override.

* `cli_openrouter_compat_test.py` is the actual reproduction test:
  spawns the bundled (or `CLAUDE_AGENT_CLI_PATH`-overridden) CLI
  against an in-process aiohttp server pretending to be the Anthropic
  Messages API, captures every request body the CLI sends, and
  asserts that none of them contain the two known forbidden patterns
  (`"type": "tool_reference"` content blocks or
  `"context-management-2025-06-27"` in body or `anthropic-beta`
  header). The fake server returns a minimal valid streamed response
  so the CLI doesn't error out before we can inspect what it sent.
  No OpenRouter API key required — the test reproduces the *mechanism*
  rather than the symptom, so it's deterministic and free to run in CI.

Workflow for verifying a candidate upgrade going forward: bump the
SDK in `pyproject.toml`, push the commit, and watch the CI run for
both tests in `sdk_compat_test.py` and `cli_openrouter_compat_test.py`.
A clean run on both means it's safe to add the new bundled CLI version
to `_KNOWN_GOOD_BUNDLED_CLI_VERSIONS` and merge.

"""Reproduction test for the OpenRouter incompatibility in newer
``claude-agent-sdk`` / Claude Code CLI versions.
Background — there are two stacked regressions that block us from
upgrading the ``claude-agent-sdk`` package above ``0.1.45``:
1. **`tool_reference` content blocks** introduced by CLI ``2.1.69`` (=
SDK ``0.1.46``). The CLI's built-in ``ToolSearch`` tool returns
``{"type": "tool_reference", "tool_name": "..."}`` content blocks in
``tool_result.content``. OpenRouter's stricter Zod validation
rejects this with::
messages[N].content[0].content: Invalid input: expected string, received array
This is the regression that originally pinned us at 0.1.45 — see
https://github.com/Significant-Gravitas/AutoGPT/pull/12294 for the
full forensic write-up. CLI 2.1.70 added proxy detection that
*should* disable the offending blocks when ``ANTHROPIC_BASE_URL`` is
set, but our subsequent attempts at 0.1.55 / 0.1.56 still failed.
2. **`context-management-2025-06-27` beta header** — some CLI version
after ``2.1.91`` started injecting this header / beta flag, which
OpenRouter rejects with::
400 No endpoints available that support Anthropic's context
management features (context-management-2025-06-27). Context
management requires a supported provider (Anthropic).
Tracked upstream at
https://github.com/anthropics/claude-agent-sdk-python/issues/789.
Still open at the time of writing, no upstream PR linked, no
workaround documented.
The purpose of this test:
* Spin up a tiny in-process HTTP server that pretends to be the
Anthropic Messages API.
* Capture every request body the CLI sends.
* Inspect the captured bodies for the two forbidden patterns above.
* Fail loudly if either is present, with a pointer to the issue
tracker.
This is the reproduction we use as a CI gate when bisecting which SDK /
CLI version is safe to upgrade to. It runs against the bundled CLI by
default (or against ``ChatConfig.claude_agent_cli_path`` when set), so
it doubles as a regression guard for the ``cli_path`` override
mechanism.
The test does **not** need an OpenRouter API key — it reproduces the
mechanism (forbidden content blocks / headers in the *outgoing*
request) rather than the symptom (the 400 OpenRouter would return).
This keeps it deterministic, free, and CI-runnable without secrets.

"""Tiny in-process HTTP middleware that makes the Claude Code CLI work
against OpenRouter on **any** ``claude-agent-sdk`` version.
Background
----------
We've been pinned at ``claude-agent-sdk==0.1.45`` (bundled CLI 2.1.63)
since `PR #12294`_ because every newer CLI version sends one of two
features that OpenRouter rejects:
1. **`tool_reference` content blocks** in ``tool_result.content`` —
introduced in CLI 2.1.69. OpenRouter's stricter Zod validation
refuses requests containing them with::
messages[N].content[0].content: Invalid input: expected string, received array
2. **`context-management-2025-06-27` beta header** — sent in either the
request body's ``betas`` array or the ``anthropic-beta`` HTTP header.
OpenRouter responds::
400 No endpoints available that support Anthropic's context
management features (context-management-2025-06-27).
Tracked upstream at `claude-agent-sdk-python#789`_.
This module starts a tiny aiohttp server that:
* listens on ``127.0.0.1:RANDOM_PORT``,
* receives every CLI request that would normally go to
``ANTHROPIC_BASE_URL``,
* strips the two forbidden patterns from the body and headers,
* forwards the cleaned request to the real upstream
(``proxy_target_base_url``, e.g. ``https://openrouter.ai/api/v1``),
* streams the response back to the CLI unchanged.
The proxy is wired via :class:`backend.copilot.config.ChatConfig.claude_agent_use_compat_proxy`.
When the flag is on, :mod:`backend.copilot.sdk.service` starts a proxy
per session, sets ``ANTHROPIC_BASE_URL`` in the SDK's ``env`` to point
at the proxy, then tears it down after the session ends.
Why a separate proxy instead of a custom HTTP transport in the SDK?
-------------------------------------------------------------------
The Python SDK delegates **all** HTTP traffic to the bundled Claude
Code CLI subprocess. Once the CLI is spawned, the only seam left is
the network — there is no in-process hook for "modify outgoing
request before it leaves the CLI". The proxy lives at that seam.
This module is intentionally orthogonal to the
:attr:`ChatConfig.claude_agent_cli_path` override:
* ``cli_path`` lets us swap **which CLI binary** we run.
* this proxy lets us **rewrite what any CLI binary sends**.
The two can be combined or used independently.

"""Tests for the OpenRouter compatibility proxy.
The proxy strips two known forbidden patterns from requests so newer
``claude-agent-sdk`` / Claude Code CLI versions can talk to OpenRouter
through the unchanged transport. These tests cover both:
* the pure stripping helpers (deterministic, no I/O), and
* the end-to-end proxy behaviour against a fake upstream server, so we
catch hop-by-hop header bugs and streaming regressions.
See ``openrouter_compat_proxy.py`` for the rationale and the upstream
issues being worked around.

#
# We're stuck on ``claude-agent-sdk==0.1.45`` (bundled CLI ``2.1.63``)
# because every version above introduces a 400 against OpenRouter:
#
# 1. CLI ``2.1.69`` (= SDK ``0.1.46``) shipped a `tool_reference` content
# block in `tool_result.content` that OpenRouter's stricter Zod
# validation rejects. See PR
# https://github.com/Significant-Gravitas/AutoGPT/pull/12294 for the
# forensic write-up that originally pinned us. CLI ``2.1.70`` added
# proxy detection that *should* disable the offending block, but two
# later attempts (Dependabot bumps to 0.1.55 / 0.1.56) still failed.
#
# 2. A second regression — the ``context-management-2025-06-27`` beta
# header — appeared in some CLI version after ``2.1.91``. Tracked
# upstream at
# https://github.com/anthropics/claude-agent-sdk-python/issues/789
# (still open at the time of writing, no upstream PR yet).
#
# This test is the cheapest possible regression guard: it pins the
# bundled CLI to a known-good version. If anyone bumps
# ``claude-agent-sdk`` in ``pyproject.toml``, the bundled CLI version in
# ``_cli_version.py`` will change and this test will fail with a clear
# message that points the next person at the OpenRouter compat issue
# instead of letting them silently re-break production.
#
# Workaround for actually upgrading: set the
# ``claude_agent_cli_path`` config option (or the matching env var) to
# point at a separately-installed Claude Code CLI binary at a known-good
# version, so the SDK Python API surface and the CLI binary version can
# be picked independently.
# CLI versions verified to work against OpenRouter from production
# traffic. When upstream lands a fix and we can confirm a newer version
# works, add it to this set rather than blanket-removing the assertion.
