From 0d35dffe379f0c34651d22c75196cb204c9ae992 Mon Sep 17 00:00:00 2001 From: Xuepoo Date: Mon, 31 Aug 2026 23:21:54 +0800 Subject: [PATCH] feat(cli): add capglyph conformance test harness (CTX-0041) Implements `capglyph conformance test --vectors [--verbose] [--json-report]` validating 1024 fixtures from CapGlyph/capglyph-test-vectors via capglyph_core::framing::open + error::classify_str. Covers valid, invalid, expired, revoked, malformed, tampered, images + manifest. Companion to capglyph-spec v1.0.0 and capglyph-core error codes. Rust harness passes 1024/1024; Python harness tools/conformance.py passes 1024/1024; wasm graph stays clean (clap/glob gated).
