Enum KgWriteError 

pub enum KgWriteError {
    Admission(Error),
    Assert(Error),
    CacheRefresh(Error),
}

Why a caller-supplied KG assert did not complete.

Why: the three failure points have genuinely different meanings to a caller. Admission means nothing was written and the caller should fix the request; Assert means nothing was written and the daemon is at fault; CacheRefresh means the triple IS in storage but the always-injected surface is stale. Collapsing them into one opaque error would leave HTTP unable to choose 400 vs 500, and would let the third be mistaken for a clean success — which is the bug in #5524 and #4905. What: a thiserror enum over anyhow::Error. Admission is transparent so the Tier S refusal text (which names the occupants and the tool that retires one) reaches the caller unchanged. Test: kg_write_admission_refusal_leaves_storage_and_cache_untouched.

Variants

Admission(Error)

The Tier S gate refused the write. Nothing was stored.

Assert(Error)

The KG write itself failed. Nothing was stored.

CacheRefresh(Error)

The triple was stored but the prompt cache could not be rebuilt, so the fact is not yet on the always-injected surface.
