From 8dd9681fadbc3169a53d04959f2231f523639b30 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 27 Jun 2026 18:57:30 +0000 Subject: [PATCH 1/8] P3: prove TypeCompat (level 3) as a real operand-type-compatibility guarantee MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Continues the flagship semantic-proof coverage (InjectionFree level 5, SchemaBound level 2) with TypeCompat (level 3: "operand types compatible"). Adds `Typedqliser.ABI.TypeCompat`, to the same quality bar: * a small SQL type universe (`SqlType`) and a typed column environment (`ColEnv`) with a total `lookupType` resolver, reusing the existing `Query`/`Pred`/`Value` AST; * `ValueCompat`/`PredTypeCompat`/`QueryTypeCompat` — the proposition that every WHERE comparison compares a column against a value of a matching type (a bound parameter adopts the column's type; a literal is TInt; a raw splice is TText). There is no constructor for a type clash, so a mismatched comparison is uninhabited; * `decQueryTypeCompat` — a sound + complete `Dec`, so a "Proven" TypeCompat certificate is backed by a constructive witness and a type clash can never be certified; * `certifyTypeCompatSound` (a `Proven` verdict provably entails the property); `typeCompatIsLevelThree : levelNat TypeCompat = 3`; * positive control (a well-typed query, with the certifier computing to `Proven`) and negative control (`name : Text` compared to an integer literal provably cannot be certified). Verified with idris2 0.7.0: `idris2 --build typedqliser-abi.ipkg` exits 0 with zero warnings (all 7 modules). Adversarially checked — three deliberately-false proofs (wrong level ordinal, a TInt literal certified against a TText column, and a type-compatible witness for the clash query) are all rejected by the type checker.
