The 18-branch denominator counts only the branches that +the translator visited (Phase Y's recorder fires inside body +translation), so the coverage scope is "the production code reached +by these 7 proved lemmas". Production functions whose lemmas are +blocked by translator gaps (e.g. `findTokenStart`, `Delete`, +`searchKeys`, `escape.go::Unescape`) do not appear in the +denominator. Phase AA + S.2c.3 + Phase D widening would expand +that denominator significantly. + +## Pass 5 — Open follow-ups (translator gaps surfaced) + +These are real reqproof gaps, surfaced by attempting to apply the +toolchain end-to-end on a small library. They are filed here so the +reqproof team can pick them up: + +1. **Conditional early-return translator bug**. Loop bodies of the + shape `if cond { return X }` followed by code emit broken SMT + referencing `__early_val$N$M` outside the let-binding that defines + it. Manifests as Z3 errors `unknown constant __early_val$1$1` at + the prelude line. Workaround: rewrite as guarded fall-through + `if !cond { continue } return X`, but THIS PATTERN is itself + sometimes broken when there are TWO conditional returns inside + the loop (`findTokenStart`). Phase S.2c.4 follow-up. +2. **`E_SWITCH_NOT_SUPPORTED`**. `switch` statements inside loop + bodies (and elsewhere) need a lowering. Many idiomatic Go + patterns (jsonparser's tokenizer is a representative example) + use switch; refactoring is invasive. +3. **Character literals inside loop bodies**. The translator rejects + `c == ' '` style comparisons; users must replace with the integer + ASCII value. Trivial to author once known but a friction point. +4. **`E_FUNCTION_CALL` for type conversions**. `int(c)` on a `byte` + is rejected as an unsupported function call even though the + conversion is a no-op at the SMT-Int level. Phase D widening. +5. **`E_SLICE_EXPR` for slice expressions**. Disqualifies any + function whose body uses `data[:i]` / `data[i:]`. Workaround + exists (recursive helper + `// reqproof:decreases`) but it is a + significant authoring lift for non-trivial functions. +6. **Free package constants**. `combineUTF16Surrogates` references + `supplementalPlanesOffset`, etc. The translator should inline + const declarations. +7. **Multi-lemma single host**. Two consecutive + `// reqproof:lemma` directives on the same function host + silently dropped the second lemma during scanning. Workaround: + put the second lemma on a thin alias function (we did this for + `isUTF16EncodedRune_high_excluded`). Phase R follow-up. +8. **Phase AA — auto-OOB obligations**. The Delete bug is a runtime + index-out-of-range panic. With Phase AA we would not need the + snippet at all — every `data[i]` read in `Delete` would carry + an automatic `0 <= i < len(data)` proof obligation, and the + pre-fix code would fail to verify with the SAME counterexample + (`prevTok = -1`). + +## Recommendation for the jsonparser team + +1. The seven proved lemmas are cheap regressions: 7 PROVED in <60ms + total Z3 time, cached at `.proof/lemma-cache.json`. CI should run + `proof verify-lemma --solver z3 --tags reqproof_proof ./...` as + part of the existing test job. A future code change that + accidentally removes the `prevTok > -1` guard from Delete will + re-trigger the COUNTEREXAMPLE on + `deleteCleanupFixed_prevTok_nonneg`, and CI will fail. +2. The snippet file `parser_delete_snippet_proof.go` is a + regression test for the bug class. Adding similar snippets for + any future Delete/Set OOB fix is a small, repeatable pattern. +3. Once Phase AA lands, the snippet can be retired in favor of an + automatic OOB obligation on the production `Delete` body. diff --git a/docs/reqproof-item3-application.md b/docs/reqproof-item3-application.md new file mode 100644 index 00000000..9e216c4b --- /dev/null +++ b/docs/reqproof-item3-application.md @@ -0,0 +1,174 @@ +# Reqproof Item #3 — Application to jsonparser + +This doc records the dogfooding result of applying reqproof's +`feat/z3-roadmap` items #1 (path-conditions), #2 (variadic + +multi-return), and Phase AA verify-safety to the jsonparser package. + +- Reqproof revision: `feat/z3-roadmap` HEAD `d17622a9`. +- jsonparser revision: `fix-oss-fuzz-delete-leading-comma` HEAD `80cf537`. +- Date: 2026-05-01. + +## Pass 1 — lemma corpus re-run with the new toolchain + +Command: + +```sh +go run ./cmd/proof verify-lemma --solver z3 --solver z3,cvc5 \ + --tags reqproof_proof --no-cache /Users/leonidbugaev/go/src/jsonparser/... +``` + +Result (pre-item-#3 corpus, 23 lemmas): + +| verdict | count | +| -------------- | ----- | +| PROVED | 22 | +| COUNTEREXAMPLE | 1 | +| TIMEOUT | 0 | +| UNKNOWN | 0 | +| TRANSLATION | 0 | + +The single COUNTEREXAMPLE is the deliberately-falsifiable +`deleteCleanupBuggy_prevTok_nonneg_falsifiable` lemma in +`parser_delete_snippet_proof.go` (the OSS-Fuzz Delete pre-fix +witness).
