- Migration: compliance_uploads, compliance_items, compliance_notes tables
with indexes on (hostname, metric_id) identity key and team/status
- Python parser (parse_compliance_xlsx.py): reads NTS_AEO xlsx, extracts
non-compliant assets from all detail sheets, parses Summary sheet for
metric health data and overall scores, outputs JSON to stdout
- Route (/api/compliance): preview/commit upload flow with diff summary,
items endpoint grouped by hostname with seen_count tracking, metric
summary endpoint for health cards, notes endpoints keyed on
(hostname, metric_id) persisting across uploads
- server.js: register compliance router at /api/compliance
- .gitignore: exclude planning docs and xlsx source files
