Friday started with a single commit across 1 repo that ended up being the whole story. I pushed a time-shift recording feature, and it was one of those builds where a big chunk of the codebase shifted in one direction.
The commit landed at +4197/-1470 across 54 files. That's not a minor tweak, that's a structural change, and it showed everywhere from the backend environment files through the live transcription API to the new NPU acceleration path.
I built out an npu_main.py and an npu_config.json alongside the existing recording and transcription routes. The NPU side handles the heavy lifting for time-shift recording, and the config lets it tune itself without hardcoding. HTTPS support came in at the same time, so the recording endpoints are secure end to end now.
md` in there, which tells the story: I spent a solid stretch overnight getting this right, then consolidated the transcriber pieces and wrote it up.
The live transcription module got updated too, and the database models changed to accommodate the new recording format. There's an OVERNIGHT_WORK_COMPLETED.md and a TRANSCRIBER_CONSOLIDATION.md in there, which tells the story: I spent a solid stretch overnight getting this right, then consolidated the transcriber pieces and wrote it up.
Fifty-four files touched. That's a lot of code paths for a single feature, but time-shift recording is fundamentally a big feature, not a small one. It touches recording, transcription, acceleration, configuration, HTTPS, database schemas, and documentation all at once.
Also today: I updated the CLAUDE.md and the microphone access guide so the next person who picks this up doesn't have to reverse-engineer the same decisions.
4197 lines added, 1470 removed, fifty-four files. The commit message said it plainly, but the scale doesn't show in the message itself. What matters is that the feature ships clean: time-shift recording works, it uses the NPU when available, and it talks over HTTPS.
