Cannot insert a record with an id of 0 (zero) if the id field is a primary key

Describe the undocumented(?) featurette
Cannot insert a record with an id of 0 (zero) if the (int) id field has a primary key constraint; upsert succeeds but the record returned will have an id of 1 not 0 (in a previously empty table).
Upsert works fine if the id field is not a pk. However, if you subsequently specify the id field as a pk and query with ["id", "=", 0] the record will not be found until the pk constraint is lifted.
Edit: Further investigation shows related behaviour if the id field is not a pk but has a unique index constraint. Then it is possible to insert a record with id=0, but it will not be found without the predicate code shown below in Workaround.

Expected behavior
Would expect an id of 0 to be acceptable in a pk field?

Workaround
Do not specify id field as pk
Add unique index instead
Change predicates:
Use .where(["id", "<=", id], "AND", ["id", ">=", id]) which will find id == 0
instead of .where(["id", "=", id]) which won't

Example: refers to main problem not the workaround Link to CodePen

const { resolvePath } = require("@nano-sql/core/lib/utilities")
const nSQL = require("@nano-sql/core").nSQL //@nano-sql/[email protected]
const moment = require("moment")

nSQL().createDatabase({
  mode: "TEMP",
  id: "id0",
  tables: [
    {
      name: "notes",
      model: {
        // pk == primary key, ai == auto increment,
        //"id:int": { min: 0, pk: true, ai: true }, //can't insert a record with id = 0
        "id:int": { min: 0, pk: false, ai: true }, //works ok - can insert id = 0
        "parentId:int": { default: 0 }, // parent note or top level if 0
        "special:bool": { default: false },
        "title:string": { default: "New Note" },
        "contents:string": { default: "" },
        "selected:bool": { default: false },
        "created:date": { default: () => moment().toJSON() },
        "lastModified:date": { default: () => moment().toJSON() }
      }
    }
  ]
})
  .then(() => {
    //insert note with id = 0
    nSQL("notes").query("upsert", { id: 0 })
      .exec()
      .then((rows) => {
        console.log(`Line 31: rows: ${JSON.stringify(rows)}`) // works BUT - id is not 0 : [{"id":1,"parentId":0, ... }]
      })
  })
