Review of the #1–#9 ingester roadmap found two real-but-small gaps; this closes both. #5 (live posts progress) shipped at per-chunk granularity — _apply_backfill_ lifecycle accumulated DownloadResult.posts_processed AFTER each chunk, so the badge didn't move during a chunk (up to ~14.5 min) and over-counted the re-walked resume page. The plan called for within-chunk live updates. Move ownership of _backfill_posts into the ingester: ingest_core writes a monotonic absolute (posts_base + net-new) via _checkpoint_posts at each page boundary and once at the end, EXCLUDING the resumed page so it no longer inflates across chunks. download_service seeds posts_base from prior chunks and stops touching the key (the lifecycle now carries the ingester's committed value forward). #8 (per-media transient/permanent retry) covered only the plain-GET path (_fetch_to_file); the Mux/video path returned None on any yt-dlp failure with no retry. Give _run_ytdlp the same split: TimeoutExpired/OSError are transient (back off + retry up to _MAX_MEDIA_RETRIES), a non-zero exit (CalledProcessError) is permanent (yt-dlp already did its own network retries) → fail fast to the per-item/dead-letter path. Tests: live-posts absolute + resume-page exclusion + tick-doesn't-persist (test_patreon_ingester); lifecycle-leaves-posts-to-ingester rewrite (test_download_service); video transient-retry + permanent-fail-fast (test_patreon_downloader).
