New @logicsrc/plugin-credential-sharing: a provider-neutral secret-sync engine with env/.env, Doppler, Railway, and GitHub Secrets adapters behind one CredentialProvider contract. - engine: inspect -> diff -> plan -> approve -> sync -> rollback -> audit/export - dry-run is the default for sync; --approve writes; destructive changes gated - fingerprint-based diffs (salted SHA-256); raw values never printed or stored in plans/runs/audit; rollback pre-image kept in a 0600 .logicsrc vault (gitignored) - github-secrets is write-only for values (sealed-box via libsodium), so it cannot be a sync source or value-restoring rollback target - CLI: real `logicsrc credentials <providers|inspect|diff|plan|approve|sync| rollback|audit|export>` (replaces the prior stub) - 4 JSON schemas registered in @logicsrc/validators - flip logicsrc.com/credential-sharing band from coming-soon to available - 37 tests pass; full env->env lifecycle verified; artifacts schema-validate Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
