From ab39304272c3ad05b7deef84116c2a2da9118590 Mon Sep 17 00:00:00 2001 From: Adam Eivy Date: Thu, 3 Sep 2026 22:40:53 +0000 Subject: [PATCH] refactor: extract pure YouTube ingest formatting into server/lib (#6015) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `server/services/youtubeIngest.js` mixed six responsibilities in one 865-line file, so unit-testing YAML escaping or the CoS agent prompt meant importing the whole service graph (child process, brain/cos/media stores, fs) behind a wall of `vi.mock` stubs. Move the pure half — `parseVideoMetadata`, `buildIngestNote`, `buildAgentTaskContext`, `resolveObsidianPointer`, `sanitizeFilename`, `formatDuration`, `yamlString` — verbatim into the new `server/lib/youtubeIngestFormat.js`. The moved bodies are byte-identical; the service imports them and keeps orchestration, storage, and the yt-dlp spawn. The new module is surfaced through the `server/lib` barrel as a NAMESPACE export (`youtubeIngestFormat.*`) rather than a flat one: `formatDuration` collides with `fileCore.js` and `sanitizeFilename` with `mimeTypes.js`, which the barrel's collision guard rejects for flat `export *`. Tests for those four public contracts move to `server/lib/youtubeIngestFormat.test.js` and now run with no mocks at all — if that file ever needs one, something impure leaked back into lib/. The service suite keeps the URL-allowlist and cancel-escalation cases. Added coverage for the untrusted-transcript boundary notice in the agent prompt, which nothing pinned before.
