* test(reddit): add live RSS + shreddit comment fixtures Captured from reddit.com on 2026-05-29 (search.rss listing + the /svc/shreddit/comments partial), trimmed to a representative subset plus two synthetic edge cases (deleted author, negative score) for offline parser tests. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(http): add keyless get_text helper Browser-UA text fetch for RSS/HTML endpoints; returns None on any HTTP or network failure so tiered callers fall through cleanly. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(reddit): keyless RSS discovery (search.rss + listing feeds) Replaces the now-403 search.json with keyless Atom feeds, normalized to the existing reddit_public post shape. Scores are placeholder zeros, backfilled during shreddit enrichment. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(reddit): keyless shreddit comment scraper Parses <shreddit-comment> elements from /svc/shreddit/comments/r/{sub}/t3_{id} (score/author/created/permalink + thingId-anchored body) into top comments, matching reddit_enrich output. Replaces the dead {thread}.json enrichment. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(reddit): tiered keyless orchestrator Tier 0 one-shot .json (residential bonus) -> Tier 1 RSS discovery -> Tier 2 shreddit enrichment. Returns [] never raises, so the SC backup still engages when every keyless tier is empty. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(reddit): route free path through keyless pipeline (.json is dead) search_reddit_public is now a thin shim over reddit_keyless, so pipeline.py and other callers need no change. Removes the dead .json enrichment helpers; search/_parse_posts remain as the demoted Tier 0 attempt. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(reddit): request sort=top so true top comments land on page 1 Guarantees the highest-scored comments are captured even on large threads, independent of Reddit's default comment sort. Local score re-sort remains. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(reddit): recover post upvote scores via keyless listing partials The shreddit community-more-posts partial server-renders each post's score and comment count (works for normal users, not IP-gated), unlike RSS or the comments endpoint. Use it as a scored discovery source and to backfill scores onto RSS-discovered posts (subreddits derived from results when not provided). Ranking now uses real upvote score. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(reddit): listings backfill scores only on bare queries, not discovery Caught running the full pipeline on a bare topic: deriving subreddits from noisy RSS results and merging their top/hot listings flooded results with high-upvote off-topic posts. Now derived-subreddit listings are used only to backfill scores onto keyword-matched RSS posts; listing cards are merged as discovery only when the caller explicitly provides subreddits (on-topic).
