+## Compact interpretation protocol 6
+
+Fresh entity-resolution inputs freeze interpretation protocol 6. Its prompt
+receives a deterministic view of the full archived context. Only long storage
+identifier fields containing digest material (40+ hexadecimal characters) use
+short P aliases. Equal identifiers retain equal aliases; different identifiers
+remain distinct. Filenames are retained as labels where applicable. Meaningful
+source paths without digest material, human/descriptive text and database `row`
+objects remain unchanged. This is not a semantic summary or evidence ranking.
+
+Repeated origin/provenance objects are stored once in `input.shared_metadata`
+and referenced with M metadata aliases. Their author, timestamp, snapshot scope
+and other fields remain available; these aliases are not evidence source IDs.
+All B/O/C/T/E/F/N/D/X source IDs and source kinds remain present, including unread
+sources. Query filters, rows, completeness/truncation, next offsets, conflicting
+names and uncertainty remain present. JSON whitespace is reduced in this new
+prompt only. The stored full context, canonical case, raw archives and outputs
+are unchanged. Existing protocols 1–5 preserve their original request bytes.
+
+On the completed typed-names-20261015 sample, the initial interpretation messages
+previously contained 151857 characters; the compact representation contains
+83681 characters (44.9% fewer). These sizes are measured offline; this is not a claim about exact Gemini tokens, cost, or live quality.
+The next fresh LLM trial must verify role/ID correctness, item-name uncertainty,
+visibility prerequisites and investigation directions. No LLM pre-summary and
+no extra model calls are introduced. Name-resolution prompts are unchanged.
