The contained consistency consolidations; the sweeping ones are deferred with their standard documented (they're the audit's own post-1.0 refactors, and several would be reckless to do unattended). Landed: - src/main/lib/lineBuffer.ts (createLineBuffer): one newline line-splitter for streamed child-process output, replacing the duplicated buffer loop in download.ts and terminal.ts (CC3/CC4/SIMP5). Pure + unit-tested (test/lineBuffer.test.ts, 7 cases: partial lines, CRLF, empty lines, flush, multi-line chunks). download.ts keeps byte-identical marker parsing and no close-flush (yt-dlp template lines are always newline-terminated). - ytdlp.ts: getYtdlpVersion/updateYtdlp now run stderr through cleanError, the same `cleanError(r.stderr) || r.error?.message || ''` idiom already used by download/probe/indexer (CC6) — a failed check shows the trailing error line. - CL6 resolved: the one real redundancy was L15; clearDir/openFile/showInFolder are deliberate view-model wrappers (CC13), left as-is. Deferred with documented standard + rationale (CODE-AUDIT.md): CC1 (breaking persisted-key rename → migration), CC5+CL4 (security-critical updater net.request, not live-verifiable here), CC7 (cosmetic arg-order), CC9 (zod dep), CC10 (electron-store↔jsonStore split is deliberate for DPAPI), CC11 (config.ts move), CC12 (file-tree reorg), CC13→L93, CC14→L142. Verified: typecheck (node+web) + 275 tests + eslint + production build green; touched files prettier-clean. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
