DRY pass commit 3 — the observability half. ingest_core accumulated ALL
human-readable progress in log_lines → DownloadResult.stdout, persisted to the
DownloadEvent ONLY at phase 3; the real logger was used almost nowhere. So a
worker SIGKILL/OOM/hard-time-limit mid-walk left NO trace (the "task died,
no trace" mode from the recovery-sweep work).
Route run milestones through the container log too, each carrying source_id (L3
context):
- run START (platform/mode/source/campaign/resume_cursor)
- per-PAGE breadcrumb (posts/downloaded/skipped/errors/quarantined/gated/cursor)
at each page boundary — pages are minutes apart on big backfills, so this shows
how far a since-died walk got
- final SUMMARY (same string as the stdout summary)
- operator STOP
(L2 — quarantines log.warning'd — already landed in commit 1's base
_validate_path; failures log.warning via the base _failure_result; the #862 body
canary already log.error's.) log_lines/stdout content is unchanged (summary just
captured in a var), so existing assertions hold.
