Three findings from a final review pass: 1. **Worker clobbered Cancelled with Errored when impl returned None / raised mid-cancel.** The legacy per-client thread workers each had a guard (``if state != 'Cancelled': state = 'Errored'``); the shared worker dropped it. Fix: new ``_mark_terminal`` helper in BackgroundDownloadWorker reads current state before writing the terminal one and leaves Cancelled alone. SoundCloud test updated back to the strict Cancelled-only assertion (had been loosened to accept Errored as a workaround). Two new pinning tests catch the regression. 2. **Dead code in engine.py.** ``find_record`` and ``iter_all_records`` had no production callers — only tests. Removed them. Concurrent-add stress test rewritten to use the per-source iterator that's actually in use. 3. **Silent ``except Exception: pass`` in cross-source query methods.** Faithful to legacy behavior (one source failing shouldn't take down aggregation) but Cin's standard is "log even when you swallow." Each silent-swallow site now logs at debug level so the source name + exception are inspectable without adding warning-level noise. Suite still green (2049 passed). |
