Citation Lookup

Exact citation lookup is a deterministic key check. Honesty note: simplified toy corpus; jurisdictions vary; the pinned first step states the as-of date; not legal advice; retrieval points to sources and does not answer the legal question.

Citation lookup is a key check

The stated process is exact lookup. The model compares the authored citation key to corpus citation fields and reports a lookup status.

lookup=exact key comparison\text{lookup}=\text{exact key comparison}

Example found and missing keys

One lookup asks for Fed. R. Civ. P. 6(a)(1). The variant lookup asks for Toy Citation 0.

lookup variants=2\text{lookup variants}=2

The model returns status rows

The first key returns found and record id rule6. The variant key returns not_found.

found traces=1,missing traces=1\text{found traces}=1,\quad \text{missing traces}=1

Diagram note

The diagram keeps lookup status separate from any legal reading. A found citation is a pointer to a record.

Summary

Exact citation lookup is deterministic: either the corpus key is present or the model records a miss.
