`sa = get_server_args()` followed by `sa.field` reads the same startup record as
the direct form; the read ratchet added in the previous slice pinned twelve of
them as the remaining surface. Eleven now read the accessor for what they
actually want:
- `is_enable_moe_cp_allgather` compares the attention-CP and MoE-DP sizes to
decide whether a forward needs an allgather, so it reads the live topology
through `get_parallel()` — the same source `get_moe_cp_size()` right above it
already uses. Both groups exist once model-parallel init has run, which is
before any forward.
- The DeepSeek MLA decode-backend gate and Inkling's attention paths read
`get_exec().kernel`; Inkling's KV-dtype checks read `get_model()`. These are
per-runner fields, and the value they get is the config published for the
runner being built — unchanged from what the alias returned.
- The int8 mamba checkpoint pool reads `get_exec().mamba`. It keeps its guard
for callers that construct the pool with no published config; that guard now
catches the namespace accessor instead of the slot.
`model_loader`'s `moe_dp_size` stays on the instance and is exempt: the dict it
belongs to already reports the live size under `"dp"`, so that entry is the
configured intent, and `get_parallel()` shadows the name with the live value.
Alias-form baseline 12 -> 0. What remains on `get_server_args()` in the package
is the derived API (properties and methods computed from several fields plus the
HF config) and four config-intent reads of live-shadowed sizes, each exempt by
name with its reason.
