01 / IMPLEMENTATION & CONTRIBUTION
What the work involves
Donald built transcript ingestion, streaming APIs, source-linked distillation, creator knowledge graphs, and query/feed views, then improved concurrency and mobile behavior.
Technical depth
Fast summary and deeper analysis are separated. A bounded semaphore permits three ingests, per-channel locks protect shared profiles, and temp-file replacement keeps writes atomic. NDJSON heartbeats keep long jobs observable. Graph validation restricts source video IDs and requires an actual cross-video connection; graph failure does not discard primary distillation.

What came out of it
A Chinese-first application connects videos to summaries and cross-video ideas. Bounded ingestion, per-channel locking, atomic writes, and validated source IDs keep long-running knowledge workflows observable and recoverable.

Source context & project scope
Transcript content and creator conclusions are external material, not Donald-authored beliefs or writing.
Uses Claude CLI for analysis; this is not local Qwen inference.
Live uptime, extraction accuracy, user adoption, and all historical browser outcomes were not reverified.
Only implementation and test source were inspected; stored transcripts, chat logs, and personal library contents were excluded.
Two-stage processing, subprocess model invocation, bounded concurrency, per-slug locking, atomic writes.
