Taxonomy Sidecar / taxonomy-sidecar (pull_request) Has been cancelled
- Wrap snapshot updates in transactions with error context for each child table
- Add sidecar retry with exponential backoff (3 attempts, 2s base, 10s max, 30% jitter)
- Add HTTP timeout (30s per request) and SEC rate limiting (10 req/s) in Rust
- Add XBRL validation with status reporting (checks root element, tag balance)

Consolidate metric definitions with Rust JSON as single source of truth
...
- Add core.computed.json with 32 ratio definitions (filing + market derived)
- Add Rust types for ComputedDefinition and ComputationSpec
- Create generate-taxonomy.ts to generate TypeScript from Rust JSON
- Generate lib/generated/ (gitignored) with surfaces, computed, kpis
- Update financial-metrics.ts to use generated definitions
- Add build-time generation via 'bun run generate'
- Add taxonomy architecture documentation
Two-phase ratio computation:
- Filing-derived: margins, returns, per-share, growth (Rust computes)
- Market-derived: valuation ratios (TypeScript computes with price data)
All 32 ratios defined in core.computed.json:
- Margins: gross, operating, ebitda, net, fcf
- Returns: roa, roe, roic, roce
- Financial health: debt_to_equity, net_debt_to_ebitda, cash_to_debt, current_ratio
- Per-share: revenue, fcf, book_value
- Growth: yoy metrics + 3y/5y cagr
- Valuation: market_cap, ev, p/e, p/fcf, p/b, ev/sales, ev/ebitda, ev/fcf
