"""Regression test for #3718 -- /api/models/live skips probe for custom providers.
"""Handler-level regression tests for /api/models/live custom-provider probing.
When a custom provider (``custom_providers`` entry in config.yaml) has a
``model:`` field but no ``models:`` allowlist, the live endpoint previously
populated ``ids`` from the config entry and then skipped the live ``/v1/models``
probe (guarded by ``if not ids``). The fix collects config-specified model IDs
in a separate ``_config_ids`` list so the live fetch always runs, and merges
config entries as a fallback after the fetch.
These tests invoke the real ``routes._handle_live_models`` and inspect the
emitted ``models`` payload. Earlier revisions of this file re-implemented the
filtering loop locally, which meant they passed unchanged even with the
production filter deleted (a vacuous oracle). Every case here must fail if the
allowlist gating in ``api/routes.py`` regresses.
Covered shapes:
* native ``models`` list → live catalog filtered
* JSON-array-string ``models`` → live catalog filtered (#7120 class)
* Python-literal-string ``models`` → live catalog filtered
* singular ``model`` only, no ``models`` → live catalog NOT gated
* malformed serialized ``models`` → safe, treated as scalar name
* allowlisted model absent from live catalog → appended
* live probe failure → falls back to config ids
* dict-shaped ``models`` (Agent setup) → live catalog NOT gated (per-model
metadata, not an allowlist)
* dict-shaped ``models`` + ``discover_models:
false`` → pinned to dict keys (explicit opt-out)
* ``models_discovered: true`` catalog → live catalog NOT gated (discovery
metadata is not an allowlist)
* discovered + ``discover_models: false`` → still pinned (explicit opt-out)

"""Regression coverage for issue #7421: configurable
``HERMES_WEBUI_MAX_SESSION_RESOLVE`` cap on the heavy
full-transcript resolve semaphore.
The cap is hardcoded to ``2`` in
``api.models.py::_FULL_SESSION_RESOLVE_MAX_CONCURRENT``. The
maintainer's diagnosis is that the literal 2 is too low for
high-concurrency deployments where several parallel active
sessions all need a full-transcript resolve, and that the
deeper per-read cost is tracked separately in #7310. This PR
is the self-contained first step: read the cap from the env
var so operators can raise it without code changes, while
preserving the previous default of 2 and bounding the upper
end against typos like ``=999999``.
#7656 re-gate (9/22 23:18): the previous round used a private
``_import_models_with_env`` helper that did ``sys.modules.pop``
on ``api.models`` and re-imported to recompute the module-level
cap constant. Modules already imported (``api.routes``,
``api.streaming``, ...) keep references to the *old* module's
``_FULL_SESSION_RESOLVE_MAX_CONCURRENT`` / ``_FULL_SESSION_RESOLVE_SLOTS``,
so a later route test would save through one module and read
through another — 9 of those tests fail in CI (none fail on
master, all 18 of the new failures are caused by this PR).
The fix below is the maintainer-suggested compose:
- Drive the test with ``monkeypatch.setenv`` so the env var is
restored at fixture teardown — no leak to other test files
- Test ``_read_max_session_resolve_concurrent()`` directly
(the function is already pure: only reads ``os.getenv``) so
no module reload is needed
- For the single test that needs the module-level constant
(``_FULL_SESSION_RESOLVE_MAX_CONCURRENT``), verify it equals
the helper's return value at import time — that is the real
production contract, and it is cheap to assert because the
helper itself only reads the env var

# - all three call sites use the shared guarded helper
