Each removal verified by checking actual production callers (frontend,
electron, internal HTTP, MCP-server subprocesses) — not just test
references. Symbols whose only callers were tests are removed along
with those tests.
Production removals (~390 LOC):
- backend/main.py
- websocket_session: drop `agent:edit_message` WS branch. Frontend
only ever uses HTTP `POST /api/agents/sessions/{id}/edit_message`
(frontend/src/shared/state/agentsSlice.ts); nothing on the wire
sends a WS message of this type.
- backend/apps/agents/agent_manager.py
- AgentManager._build_connected_tools_context (~80 LOC): zero call
sites in production; the connected-tools system-prompt context is
built inline in _compose_system_prompt now.
- AgentManager._approx_tokens / _summarize_message_block: pure
helpers whose only callers were tests. The compaction path uses
LLM-driven _maybe_compact instead.
- backend/apps/agents/browser_agent.py
- clear_browser_history: only used by tests. _browser_history is
pruned via the size cap inline.
- MODEL_MAP constant: never read.
- backend/apps/agents/mcp_preflight.py
- DISCOVERY_SCAFFOLDING (~25-line system-prompt block): defined but
never appended anywhere. The header comment described an intended
use that the codebase no longer has.
- backend/apps/agents/providers/registry.py
- thinking_params_for, _is_9router_available, OPENROUTER_BASE_URL,
get_context_window: zero callers in production. Thinking-params
routing is done by the provider classes directly; 9Router presence
is detected at request time; context-window numbers are stamped
onto sessions from BUILTIN_MODELS at launch.
- backend/apps/agents/tools/{base,web}.py
- BaseTool.get_schema (abstract) + WebSearchTool/WebFetchTool
overrides: production code in backend/apps/web/web.py instantiates
these tools and only calls .execute(); the JSON-schema lives in
the HTTP wrapper, not on the tool class.
- backend/apps/outputs/outputs.py
- _resolve_model + MODEL_MAP: tests-only.
- load_output: docstring claimed it was a public helper for "other
modules" but no module imported it.
- backend/apps/service/client.py
- set_user_id, the _user_id module global, and the dead cache short-
circuit in _get_user_id: setter was tests-only. _get_user_id now
reads user_email directly from settings on every call.
- backend/apps/settings/credentials.py
- get_provider_credentials: zero callers. The sibling get_agent_sdk_env
is kept (it has the explicit "Legacy helpers" keep-comment).
Test updates:
- test_agent_manager_unit.py: drop _approx_tokens / _summarize_message_block
cases (5 tests), update module docstring index.
- test_browser_agent_unit.py: drop clear_browser_history cases (2 tests)
and the unused _Boom helper class in the repr-fallback test.
- test_outputs_unit.py: drop _resolve_model / load_output cases
(4 tests), update docstring + import list.
- test_v2_invariants.py: drop get_context_window tests + get_schema
assertions on web tools (kept name + BaseTool inheritance checks).
- test_service.py: rewrite the 4 set_user_id-driven tests to drive
user_id through settings.user_email instead, so _get_user_id's live
envelope-stamping path stays covered.
Verification:
- ruff --select F401,F811,F841 backend/ → clean.
- pytest backend/tests/ → 1167 passed, 1 deselected (pre-existing
sandbox git test, unrelated). No tests dropped silently — every
deletion is paired with the corresponding test removal/rewrite.
- Dead-code scan re-run: dead WS events 1→0, Tier-2 high-confidence
14→11 (residue is SDK-callback `context` params + Pydantic `cls`
validators — both false positives vulture can't see through),
vulture total 165→145.
Total diff: -565 / +34 LOC across 15 files.

Auto-fixed 52 ruff F401 findings (unused imports) across 22 files
in backend/ and backend/tests/. Manually resolved 8 F841 unused
locals that ruff flagged as unsafe-fix:
- agent_manager.resume_session: drop dead hours_since_closed block.
- main.py mcp-meta + outputs-meta activate handlers: drop dead
reason = body.get("reason") binding (server ignores the field).
- dashboards.seed_demo, tools_lib.m365_device_login: keep _load(...)
call for its 404 side-effect, drop unused binding, add intent
comment.
- outputs.auto_run_output: keep `import anthropic` as availability
probe, mark with `# noqa: F401` and explanation.
- dead_code_scan._extract_ws_event_branches: drop vestigial
ws_handler_lines set (never written or read).
- test_browser_agent_unit.test_hash_tool_call_falls_back_to_repr:
drop the unused _Boom class+instance (the actual self-referential
bait is bad_input/bad_result; _Boom was never passed to the
function under test).
Result: 1184/1184 backend tests pass (1 deselected: pre-existing
sandbox-only git test). ruff --select F401,F811,F841 backend/ now
clean (was 60 findings).
