+# Phase 1.0DH: hash-bound snapshot query
+
+Status: `OFFLINE_QUERY_IMPLEMENTED_NO_SNAPSHOT_NO_LIVE_ACQUISITION`
+
+Phase 1.0DH implements the DG primitive for local snapshots only. It accepts an
+exact size and SHA-256 binding, rejects files larger than 64 MiB or without the
+SQLite 3 header, then opens the database with `mode=ro&immutable=1` and enables
+`PRAGMA query_only`. It never creates a result file.
+
+The only query is parameterized for fixed title `PPSA01659`. Exactly one row is
+`PRESENT`, zero rows is `ABSENT`, and duplicate rows, schema mismatch or SQLite
+errors are `UNKNOWN`. Identity and format mismatches are rejected before SQL.
+
+Synthetic tests create disposable host databases and verify present, absent,
+ambiguous and rejected cases, including absence of journal or WAL sidecars.
+These tests are not PS5 evidence. No real snapshot is tracked or available.
+
+The module contains no network adapter, socket, CLI, target source or artifact.
+It cannot retrieve the database and authorizes no console operation. The next
+offline step is to audit whether a consistent, bounded, binary-safe acquisition
+can be formed at all and, if so, define the minimum exact authorization needed.
