+- docs(releases): the 10.4.0 entry catches up to the late trains — repair routing, the vector ledger and open-gate leg, the loud config guard, the JSON-safe crossing (834149ed)

 - feat(vector): the vectored-noun scalar joins the count ledger; the open gate closes the vector leg (9730835b)

   writes to both, swaps atomically, and persists once after the swap. Reads
   never observe a partial index. `repairIndex({ rebuild: ['metadata'] })` uses
   it automatically.
+- **Incremental heal is routed.** A provider invariant that asks for the
+  incremental heal (`heal: 'repair'`) now routes to the provider's own
+  `repair()` when it exposes one — re-posting exactly what its ledger names,
+  never a store-sized rebuild — and the post-heal re-read of the report decides
+  success; a repair that doesn't converge is recorded with the escalation named.
+- **The vector family joins the count ledger.** `getCanonicalCounts()` gains
+  `vectors: { all }` — the count of canonical entities holding a real vector
+  (deferred-embed entities count when their vector lands). And the open gate
+  closes the vector leg: a store whose canonical rows hold vectors but whose
+  derived vector index is empty now builds at `open()` (or refuses with the
+  typed error) instead of silently serving empty vector-search results.
+- **An unknown storage config shape fails loudly.** A nested `config` object
+  carrying a path-shaped key (a shape that was never supported) used to fall
+  through silently to the default shared directory — every instance writing one
+  store while callers believed each had its own. It now throws, naming the
+  canonical `path` key.
+- **Relation index rows are JSON-safe.** Internal endpoint identifiers can no
+  longer ride the metadata-index crossing (a native provider serializes it);
+  they stay on the graph operations where they belong.
 - **A broken accelerator install can never read as "not installed."** The
   auto-detection free pass now requires the resolution error to name the
   accelerator package itself, exactly — a missing platform-binary sibling
