Pipeline
Step 1
Raw source snapshots
Every fetch job stores source URL, timestamp, status, raw hash, parser version, and storage path before parsing.
Step 2
Validation
Vote totals, required fields, representative mappings, source URLs, and campaign finance identifiers must validate before publication.
Step 3
Issue mapping
Every roll call is mapped to either a specific issue question or a broader scored category that fits the vote.
Step 4
Scoring
Each reviewed yea or nay vote is compared with the user's selected stance and weighted by importance from 1 to 5.
Known Limitations
This first build is federal-only. Broad procedural, nomination, and policy-area mappings are scored with confidence labels so users can decide whether those categories matter to their personal alignment profile.
