 database connection and executes neither staging nor apply. Its output is the
 review packet, not canonical knowledge.
 
+The VPS also exposes a bounded preparation command for one text-like filesystem
+document (or a binary artifact with a separately supplied strict UTF-8
+extraction):
+
+```bash
+teleo-kb prepare-source \
+  --artifact /home/teleo/.hermes/profiles/leoclean/state/kb-source-inbox/source.md \
+  --identity document:stable-source-id \
+  --source-key stable_source_key \
+  --source-type article \
+  --title "Stable source title" \
+  --locator artifact://stable/source-id \
+  --output-dir /home/teleo/.hermes/profiles/leoclean/state/kb-source-preparation/source-id
+```
+
+It queries canonical claims before extraction, caps a single document at three
+new candidates with confidence at or below `0.75`, requires exact source
+substrings, records duplicate judgments, and validates a v2 manifest through
+the source compiler. It writes private files only. A separate
+`teleo-kb propose-source` call is required to create a `pending_review` row;
+neither command applies canonical rows.
+
 The existing full-data clone canary separately proves that a reviewed packet
 can create source, claim, evidence, and edge rows and affect later reasoning.
-The next capability is to expose this compiler through Leo's bounded source
-intake command, stage its output, and join accepted packets into a corpus runner
-and replay ledger.
+The remaining recompilation capability is to join accepted packets into a
+complete corpus runner and replay ledger. One-document preparation and staging
+do not yet prove a clean database can be rebuilt semantically from every source.

+This performs a canonical claim retrieval before model extraction, allows at
+most three single-source candidates, caps confidence at `0.75`, binds every
+claim/evidence/duplicate judgment to an exact source substring, and writes
+private mode-`0600` outputs. It performs no database write. If status is
+`no_novel_claims`, inspect the duplicate judgments and do not stage an empty
+packet.
+
+After reviewing a `prepared` receipt, stage exactly one reviewable proposal:
 
 ```bash
 /home/teleo/.hermes/profiles/leoclean/bin/teleo-kb propose-source \
-  --artifact /path/to/source.bin \
