- adapters/__init__.py: add load_queries() + source_config() (stdlib json,
safe fallback to {} on missing/corrupt config so pipeline never crashes).
- config/queries.json: per-adapter blocks (hackernews.keywords, arxiv.categories,
reddit.subreddits, rss.feeds+keywords, github.search_terms). JSON (not
yaml) to honor Athena's dependency-free runtime; PyYAML avoided.
- hackernews: drop class AI_KEYWORDS + the DUPLICATE inline list inside
_is_ai_relevant() (the internal drift Ty flagged). Now loads self.ai_keywords
from config. Simplified matching to single substring pass (boundary variants
'ai ',' ai','ai-','-ai' approximate word-boundary; dropped the niche
'compute+tech-context' guard as not worth centralizing).
- reddit: DEFAULT_SUBREDDITS kept as fallback; __init__ prefers config.
- arxiv: DEFAULT_CATEGORIES kept as fallback; __init__ prefers config.
- rss: FEEDS + AI_KEYWORDS kept as module fallbacks; __init__ prefers config.
Keywords stay regex form (re.search) as in original.
- github: trending queries moved to config search_terms; fallback retained.
- DELETE reddit_proof.py: standalone PoC v5 at repo root, own main()+init_db()
+ direct INSERT OR REPLACE, NOT in cron, NOT imported anywhere -> dead
code. Also removes its byte-duplicate SUBREDDITS.
NOTE: fallback class constants remain intentionally (issue #7 cut #5: safe
rollout). Curation VALUES now live in one file; the constants are inert
unless config/queries.json is missing.
Verified: all adapters compile; config loads (HN 46 kw, RSS 10 feeds);
full dry-run fetches all 6 sources; grep confirms HN internal dup list gone.
Bug: sort=stars returned the same viral repos every cycle (ponytail 77K⭐
dominated for 26 days). A 5-day-old repo with 3K stars (600/d) was
ranked below it despite having nearly 2x the growth velocity.
Fix:
- Fetch repos created in last 30 days (was 14)
- Re-sort by velocity (stars/day) instead of total stars
- Score formula: 70% velocity + 30% absolute stars
- Added 3rd query for breadth (autonomous agent OR AI tool)
- Added stars_per_day to raw_metadata for queryability
- Added velocity field to metadata
