AndyMik90	cba050243e	fix(test): use path.join in migration tests for Windows compatibility Path constants used string interpolation with forward slashes, but the implementation uses path.join() which produces backslashes on Windows. The mock existsSync did exact string matching and never found the paths. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-18 19:13:48 +01:00

Profile configs created by `claude auth login` don't include hasCompletedOnboarding, causing the onboarding wizard to appear every time Claude Code is launched.

André Mikalsen	a5670a6912	fix(build): bundle @libsql native modules + rebrand to Aperant (#1946 ) * fix(build): unpack @libsql/client native modules from asar @libsql/client has platform-specific native bindings (@libsql/darwin-arm64, @libsql/linux-x64, etc.) containing .node files that cannot be loaded from inside app.asar. This causes ERR_MODULE_NOT_FOUND on app startup after updating to 2.8.0-beta.4. Add @libsql/client to rollupOptions.external so Vite keeps it as a runtime require, and add node_modules/@libsql/** to asarUnpack so electron-builder extracts the native modules to app.asar.unpacked/. Follows the same pattern used for @lydell/node-pty. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix bundled and update name + icon * fix: complete Aperant rebrand and harden native module loading - Add try/catch + type validation to loadCreateClient() in db.ts to prevent silent failures when @libsql/client native module is missing or exports are wrong (was a blocking issue) - Add path.resolve() and JSON type guard to ensureOnboardingComplete() for safer config file handling - Replace require('fs').cpSync with static import; fix console.log in production code (index.ts) - Complete "Auto Claude" → "Aperant" brand rename across ~30 remaining source files: renderer components, GitHub/GitLab PR comment bodies, User-Agent headers, MCP registry, and test assertions Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(deps): sync package-lock.json with aperant rename package.json was renamed from auto-claude-ui to aperant but package-lock.json wasn't regenerated, causing npm ci to fail in all CI jobs with "Missing: aperant@2.8.0-beta.1 from lock file". Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(security): resolve CodeQL file-system race in ensureOnboardingComplete Replace existsSync + readFileSync pattern with direct readFileSync wrapped in try/catch for ENOENT.

André Mikalsen	1308ec1433	fix(ci): use unsquashfs for AppImage verification and harden checks (#1941 ) AppImage files use SquashFS format (ELF + embedded squashfs), so bsdtar fails with "Unrecognized archive format". This was causing Linux beta builds to fail at the verification step. Changes: - Replace bsdtar with unsquashfs for AppImage inspection, with fallback to --appimage-extract and finally size validation - Use boundary-safe regex for app.asar detection (avoids false positive from app.asar.unpacked) - Tool execution failures now correctly trigger verification failure - Missing package targets are hard failures instead of warnings - Install squashfs-tools instead of libarchive-tools in CI workflows Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-13 10:49:28 +01:00

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(ci): address PR review feedback on verify-linux-packages - Use boundary-safe regex for app.asar detection to avoid false positives from app.asar.unpacked - Tool execution failures (bsdtar/dpkg-deb errors) now return issues instead of reason-only, so they correctly trigger verification failure - Missing package targets (AppImage/deb/flatpak) are now hard failures instead of warnings since all three are configured build targets Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-13 09:15:46 +01:00
