 ### Added
+- **cli: `vouch import-md` -- markdown-folder importer** (#744): a folder of
+  markdown notes could not enter a fresh KB without hand-importing each file
+  -- `vouch ingest` works per file, the inbox drop has no recursive walk or
+  re-run tracking. `vouch import-md <folder>` recursively walks `*.md`
+  (hidden dot-directories pruned, symlinked directories never chased) and
+  runs the same mechanical `extract.ingest_source` per file: each file is
+  registered as a content-addressed source, receipt-backed claims are filed
+  for its quotable spans, auto-approved when -- and only when --
+  `review.auto_approve_on_receipt` is on. Re-runs are idempotent for
+  unchanged files through a per-file content hash in
+  `.vouch/md_import_state.json`; an EDITED file is fully re-ingested
+  (documented limitation -- claim-level diffing belongs to the full #612
+  track). `--max-claims`/`--budget-chars` reuse the existing density
+  selection so a large vault doesn't firehose ten thousand spans;
+  `--no-approve`, `--min-chars`, `--json`. Purely additive: one command,
+  one module, one bookkeeping file.
 - **bench: composite guards** (#616): `efficiency`, `consistency` and `canary`
   as bounded multipliers over the composite, plus a `bench_version` stamp on
   every report. Reported **beside** the composite, never folded into it —

+"""Import a markdown folder one file at a time, through the receipt gate.
+
+The argument for building this rather than telling people "convert your
+notes and use ``vouch ingest`` per file": registering the source from the
+note's own bytes means an extracted claim quotes real offsets and its
+receipt verifies -- a property you cannot get by converting first, and it
+falls out of ``extract.ingest_source`` for free.
+
+``vouch import-md <folder>`` walks a folder recursively for ``*.md`` files
+and runs the same mechanical ingest ``vouch ingest`` runs on one file:
+each file is registered as a content-addressed source via
+``extract.ingest_source``, receipt-backed claims are filed for its
+quotable spans, and they are auto-approved when (and only when)
+``review.auto_approve_on_receipt`` is on. An import is a capture
+firehose, never a review-gate bypass.
+
+Re-running is idempotent for unchanged files: a per-file content hash in
+``.vouch/md_import_state.json`` makes a re-run against the same vault a
+no-op for anything that has not changed. An EDITED file is fully
+re-ingested -- a documented limitation, not a silent gap:
+``extract.ingest_source`` has no way to diff against what a prior version
+of the same file already contributed, so a changed note files a fresh
+batch of claims for its current content, on top of what is already
+there. True claim-level diffing is a harder problem the #612
+multi-format track can take on later.
