feat(shapes): the practice is written where it is read, and the coverage line measures the slip (milestone 439 step 6)

- reusing-code: "Before the turn ends — say what you built" — the four
  verdicts, the one classify_shapes(repo=…) call, and the component file as a
  shape. Description names the end-of-turn moment.
- shape-accounting: the writer judges; audits are the check that it held.
  The write path SUGGESTS (no more hook instances); component file rows and
  whole-file canon described; scoped covers Svelte too.
- _INSTRUCTIONS reuse line: "before the turn ends, say what you built
  (create_snippet the reusable, classify_shapes the rest)" — 1570/1600.
- Coverage line: "written-shape check (7d): N turns checked, M asked, K left
  unjudged", from the Stop hook's recorded outcomes; silent until the
  question has been put.
- test_guidance_ownership pins the new topic on reusing-code.
- prior-art hook header no longer says it stamps instance rows.

+## Before the turn ends — say what you built
+
+You are the one who knows what the code you just wrote is. The shape ledger
+records it from your answer, not from a guess made later, so give the answer
+in the turn that built it — while it is still true. When a turn wrote
+definitions nobody has judged, the plugin's Stop hook lists them once, with
+whatever evidence the machinery holds ("looks like #N", "#M is canon in this
+directory", "new"); other clients reach the same moment through
+`list_shapes(project_id, path=…)`. For each one, decide:
+
+- **Something another part of the code should reuse** → record it with
+  `create_snippet` (the fields above). Its own row becomes the canon.
+- **Built from a recorded snippet** → `instance` of it.
+- **A deliberate departure from one** → `variant`, with the why.
+- **A genuine one-off** → `exempt`, with a reason (`reason_code` such as
+  `one-off-handler`, `test-helper`, `scoped-css` or `pure-helper` indexes it).
+
+One call records them all: `classify_shapes(project_id, repo="<the repo's
+remote>", classifications=[{path, symbol, kind, status, snippet_id?, reason?}])`.
+`repo` lets a verdict land on a shape the ledger has not synced yet — the one
+you wrote a minute ago. A component file is a shape too (`kind: "file"`, named
+by its stem): when a card, chip or dialog is the reusable thing, the file is
+what you record. An unsure call is still yours to make — the reason you write
+is what the next reader judges it by — and a verdict is permanent, so each
+shape is asked about once.
