Two distinct issues, both downstream of graph-schema-smoke being unblocked.
1. **agentdb_graph-query (4 call sites) — SQLITE_MISMATCH "datatype mismatch"**
After #2431 migrated the graph writer from sql.js to better-sqlite3,
the corresponding *query* paths in agentdb-tools.ts still called
\`db.exec(sql, params)\` (sql.js semantic). better-sqlite3's exec is
a parameterless runner — the second arg is silently ignored, the
\`?\` placeholder in \`LIMIT ?\` binds to nothing, SQLite rejects with
"datatype mismatch" (SQLITE_MISMATCH).
Migrated all 4 sites — k-hop CTE, semantic mode, pagerank mode,
pathfinder — to \`db.prepare(sql).raw().all(params)\`, which gives
the same array-of-arrays shape the downstream code expects.
Reproduced bare-metal:
\`db.exec("SELECT * FROM foo LIMIT ?", [5])\` →
SqliteError: datatype mismatch (SQLITE_MISMATCH)
\`db.prepare("SELECT * FROM foo LIMIT ?").raw().all(5)\` → OK.
2. **trajectory smoke — WAL not checkpointed before sql.js readback**
Same fix pattern as smoke-graph-schema-migration.mjs in this PR.
The trajectory hooks fire-and-forget insertGraphEdge through the
better-sqlite3 writer; without closing the writer connection the
data sits in .db-wal and sql.js (which reads only the main file)
reports count=0. Call _resetBridgeDb() before sql.js readback.
Local results after fixes:
smoke-graph-query-dispatch.mjs → 21/21
smoke-graph-pathfinder.mjs → 20/20
smoke-trajectory-graph-edges.mjs → 10/10
