The module-skipped tests injected config by faking get_server_args (a
SimpleNamespace stand-in patched onto the module) or by writing fields
onto a ServerArgs instance post-publish — both invisible to the namespace
accessors the production code now reads. Re-enable them by publishing the
config they need (get_context().override_server_args seeding, scoped per
test), asserting bag state where the old assertions checked instance
write-through (declare_load_time_override is bag-only), and extending the
per-runner stubs the code genuinely reads (kv_cache_dtype_str,
max_total_tokens, context_len).
The unified-radix-cache file (which grew a large hicache/insert-walk suite
while skipped) is recovered in the same change:
- test_cache_finished_req_strips_thinking (19 parametrized classes) wrote
strip_thinking_cache onto the ServerArgs instance; the cache reads
get_serving().strip_thinking_cache — use the serving bag's scoped
override.
- test_shallower_crossing_backs_up_above_backuped_middle staged its
broken-backup-continuity setup through insert_host, which now
deliberately drops refills below an un-backed-up node under
write-through (host_insert_dropped). Build the same tree state through
an explicit backup + device eviction.
Every config-namespace-migration deferral is recovered, so the deferral
ratchet (test_migration_deferral_ratchet.py) has done its job and is
retired.
