Self-review follow-ups on the F821 sweep:
- plugins/platforms/sms/adapter.py: the optional-import block now sets AIOHTTP_AVAILABLE like
the homeassistant / webhook / whatsapp_cloud adapters, and both call sites test the flag.
Removes the `if not aiohttp is not None:` double negation left by inlining
`_aiohttp_available()`.
- tools/mcp_tool_sampling.py: `call_context` defaults to `lambda: None` so the use site is a
single call instead of an Optional guard; the only None caller was a test. The
`from __future__ import annotations` was noise (`Context` is a runtime import). Comment
names the actual cycle (mcp_tool_server_run imports this module).
- gateway/platforms/helpers.py: drop the `from __future__ import annotations` — the only
MessageEvent annotations are attribute-target locals, which are never evaluated.
- tests/gateway/test_telegram_audio_vs_voice.py, test_video_context_note.py: module-level
`from gateway.run import GatewayRunner` like the ~100 sibling files; the
TYPE_CHECKING block + `# type: ignore[name-defined]` were contradicting each other.
(tests/e2e/conftest.py and test_feishu.py keep TYPE_CHECKING deliberately: they stub
telegram/discord before importing, and FeishuAdapter is gated on optional lark_oapi.)
Mutation check: neutralising the thunk read (`captured = None`) fails
test_captured_context_is_replayed_in_consent_call; restored → 14/14 green. ty on the three
touched production files vs origin/main: 0 new, 6 resolved.
Breaks the two import cycles that forced Protocol stand-ins in the F821 sweep, so the two
sites now name the real types.
gateway/platforms/event.py (new leaf): MessageType, ProcessingOutcome, MessageEvent moved
out of base.py verbatim. Their only dependency is gateway.session.SessionSource; base.py
imported helpers.py at module level, so helpers could not name MessageEvent. Now
TextBatchAggregator is typed by the real MessageEvent. 249 importers repointed
(`from gateway.platforms.base import` -> `.event`, preserving each import's layout);
gateway.platforms.__init__ re-exports from .event. The three revert-scheduled PLUGIN-COMPAT
pointers that named these symbols (gateway.slash_commands → MessageType, dingtalk → MessageType,
photon → ProcessingOutcome) and their COMPAT_MANIFEST rows now target gateway.platforms.event.
Docs updated: ADDING_A_PLATFORM.md, adding-platform-adapters.md (en + zh-Hans).
tools/mcp_tool_sampling.py: ElicitationHandler no longer holds a back-reference to its
MCPServerTask (mcp_tool imports sampling, so the task type cannot be named there). It only
ever read owner._pending_call_context, so it takes `call_context: Callable[[], Context | None]`
and MCPServerTask passes `lambda: self._pending_call_context`. The consent call is one
`functools.partial`, run directly or inside the captured Context.
ty on the 11 touched production files vs origin/main: 0 new diagnostics, 14 resolved.
(The one `source: SessionSource = None` diagnostic moves with the class; typing it Optional
exposes ~60 unguarded call sites — separate follow-up.)
Tests: tests/gateway + tests/plugins + tests/tools + touched files, 18,235 passed; the 31
failures reproduce identically on origin/main (macOS /private/tmp, systemd socket,
long-path fixtures, live-service tests).
Sweep of `ruff check . --select F821 --target-version py311`: 2,234 hits. 2,201 are left
alone on purpose: tui_gateway (2,169; bind_module rebinds bodies onto server.py globals,
all names verified to resolve there), the Feishu adapter (27; globals().update() SDK
binding) and the godmode script (5; dead standalone script). The other 33 were all
genuine defects. No lint config change; no TYPE_CHECKING escape hatches — every
annotation names a real, imported type; ty on the touched files: 0 new diagnostics.
- gateway/slash_commands.py: HISTORY_UNREADABLE never imported after #102117
→ NameError on the /btw error branch (same one-liner as #102952).
- gateway/platforms/whatsapp_common.py: `-> Path` return annotation with no Path
import (the body uses `_Path`). Never raised at runtime thanks to
`from __future__ import annotations`, but `typing.get_type_hints()` and ty
both fail on it.
- gateway/run.py: ActivityProvenance imported at module level
(agent.session_activity has no gateway deps); stringly annotation and the
lazy in-function import are gone.
- tools/patch_parser.py: PatchResult imported at module level; real return
annotation. The "avoid circular import" lazy import guarded a cycle that
does not exist (file_operations_common never imports patch_parser).
- gateway/platforms/helpers.py: base.py imports helpers at module level, so
MessageEvent cannot be named here; TextBatchAggregator only reads .text and
.source, so it is typed by a BatchableEvent Protocol that MessageEvent
satisfies structurally.
- tools/mcp_tool_sampling.py: mcp_tool imports this module, so MCPServerTask
cannot be named here; ElicitationHandler only reads
owner._pending_call_context, typed by an ElicitationOwner Protocol.
- plugins/platforms/sms/adapter.py: aiohttp is an optional dep ([messaging] extra) →
module-level try/except ImportError binding `aiohttp = web = None`, the pattern the
homeassistant / webhook / whatsapp_cloud adapters already use. Retires three lazy
in-function imports and the `_aiohttp_available()` wrapper; `_handle_webhook` typed
`web.Request -> web.Response`.
- plugins/platforms/teams/summary_writer.py: plain module-level `import httpx` — httpx is a
hard core dependency (pyproject `httpx[socks]==0.28.1`), so the lazy import and the
"imported on every CLI start" docstring premise were both wrong (plugin discovery never
imports this module; it is reached only via the Teams adapter / meeting pipeline).
Tests:
- tests/hermes_cli/test_config.py: a test body orphaned by the wave-1 prune
(6b81590c55) sat inside the class as dead code with self/tmp_path unbound
— header restored, so the v11→12 custom_providers migration is covered.
- tests/tools/test_mcp_tool.py: @staticmethod recursing on `self` in the
win32 branch; call portalocker directly.
- tests/test_background_review_list_shapes.py: main() still ran 3 pruned tests.
- tests/agent/test_cursor_optimizations_parity.py: bench() used names only
imported inside a sibling test.
- GatewayRunner / FeishuAdapter / Dict / Optional: missing imports.
