One source fix (web_server category merge) + five test updates that
didn't travel with their feature PRs. All 13 failures on the 04-19
CI run on main are now accounted for (5 already self-healed on main;
8 fixed here).
Changes
- web_server.py: add code_execution → agent to _CATEGORY_MERGE (new
singleton section from #11971 broke no-single-field-category invariant).
- test_browser_camofox_state: bump hardcoded _config_version 18 → 19
(also from #11971).
- test_registry: add browser_cdp_tool (#12369) and discord_tool (#4753)
to the expected built-in tool set.
- test_run_agent::test_tool_call_accumulation: rewrite fragment chunks
— #0f778f77 switched streaming name-accumulation from += to = to
fix MiniMax/NIM duplication; the test still encoded the old
fragment-per-chunk premise.
- test_concurrent_interrupt::_Stub: no-op
_apply_pending_steer_to_tool_results — #12116 added this call after
concurrent tool batches; the hand-rolled stub was missing it.
- test_codex_cli_model_picker: drop the two obsolete tests that
asserted auto-import from ~/.codex/auth.json into the Hermes auth
store. #12360 explicitly removed that behavior (refresh-token reuse
races with Codex CLI / VS Code); adoption is now explicit via
`hermes auth openai-codex`. Remaining 3 tests in the file (normal
path, Claude Code fallback, negative case) still cover the picker.
Validation
- scripts/run_tests.sh across all 6 affected files + surrounding tests
(54 tests total) all green locally.
Users whose credentials exist only in external files — OpenAI Codex
OAuth tokens in ~/.codex/auth.json or Anthropic Claude Code credentials
in ~/.claude/.credentials.json — would not see those providers in the
/model picker, even though hermes auth and hermes model detected them.
Root cause: list_authenticated_providers() only checked the raw Hermes
auth store and env vars. External credential file fallbacks (Codex CLI
import, Claude Code file discovery) were never triggered.
Fix (three parts):
1. _seed_from_singletons() in credential_pool.py: openai-codex now
imports from ~/.codex/auth.json when the Hermes auth store is empty,
mirroring resolve_codex_runtime_credentials().
2. list_authenticated_providers() in model_switch.py: auth store + pool
checks now run for ALL providers (not just OAuth auth_type), catching
providers like anthropic that support both API key and OAuth.
3. list_authenticated_providers(): direct check for anthropic external
credential files (Claude Code, Hermes PKCE). The credential pool
intentionally gates anthropic behind is_provider_explicitly_configured()
to prevent auxiliary tasks from silently consuming tokens. The /model
picker bypasses this gate since it is discovery-oriented.
