feat: WASM Component Model signing support (FEAT-11, SC-20, SC-21)#74
Conversation
Component model signing works because the parser already accepts component headers and the full-module hash covers all bytes including nested modules encoded inline. Added: - component.rs: ComponentSectionId enum (informational) - 2 signing tests (sign/verify roundtrip + tamper detection) - 1 Kani proof (header mutual exclusivity) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
WASM Component Model signing now works. The existing parser already accepts
component headers and the full-module hash covers all bytes including nested
modules encoded inline — no recursive traversal needed.

The v0.6.1 release verification failure (
wsc-component.wasm"Parse error")was caused by the component binary being a valid WASM component, but the test
was using the wrong CLI flags. Component signing works with the standard
sign/verifycommands.🤖 Generated with Claude Code
