From d7f07fb74543b513550301edc2a3a7ef12771202 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 5 Jun 2026 05:30:58 +0000 Subject: [PATCH 1/4] proof(cerro-torre): fix SafePath false-theorem type (normalizedIsSafe prerequisite) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit normalizedIsSafe was false AS STATED, not merely unproven: SafePath's grammar (SafeEmpty | SafeComponent c rest => c ++ "/" ++ rest) only admits trailing-slash paths {"", "a/", "a/b/"}, while normalizePath (split/filter/joinBy) produces NO trailing slash {"", "a", "a/b"}. The two languages overlap only at "", so SafePath (normalizePath p) was uninhabited for every non-empty path — the idris_crash postulate masked an impossible theorem. Redesign SafePath to model normalized relative paths correctly: - SafeSingle: a single FINAL component (the no-trailing-slash leaf). - SafeComponent now also requires a NON-EMPTY rest (so the only leaf is SafeSingle, forcing every "/"-segment through the per-component checks). - Each component must be '/'-free, expressed as Not (charsElem '/' (unpack c) = True) over List Char (provable, reduces; no opaque isInfixOf, no Char-eq axiom). This is load-bearing for SOUNDNESS: with only "doesn't start with /", a single "component" like "a/../x" would sneak a ".." past the not-".." check. absolutePathRejection re-proven against the 3 constructors via a new slashPrefixImpliesCharsElem bridge (prefixNative + nonEmptyUnpack + andLeftTrue + charsElemHere) — no new trusted base, Bool-level only. Build green (cerro-torre.ipkg 7/7). normalizedIsSafe stays a now-correctly-typed postulate; its discharge (verified joinBy + splitNoDelim/dotDotInfixOfJoin axioms) is the next step. https://claude.ai/code/session_01EsxEhRW4rDbxMo2c9xaa7Z --- PROOF-NEEDS.md | 27 +++---- .../verification/idris/ImporterProofs.idr | 71 ++++++++++++++----- .../verification/idris/StringLemmas.idr | 16 +++++ 3 files changed, 85 insertions(+), 29 deletions(-) diff --git a/PROOF-NEEDS.md b/PROOF-NEEDS.md index a66506dd..2bd5c555 100644 --- a/PROOF-NEEDS.md +++ b/PROOF-NEEDS.md @@ -161,8 +161,8 @@ axioms, e.g. boj-server SafetyLemmas).

Implemented + verified the fix locally against affinescript HEAD 58dc2a0 (458-test suite green incl. a new WASM-target regression test; zero regressions on the conformance+modules corpus). Persists the git-apply-able patch, a before/after repro script, and the ready-to-file new-issue text so it survives container reclaim and a future affinescript-scoped session can land it. Refs #96.
