Custos turns every contract into a row of facts you can actually read

A new Key Terms panel pulls the seven things lawyers actually look for out of every uploaded contract - and tracks how they change on re-upload.

contract-reviewanalytics

Custos's fork now extracts a structured snapshot from each contract: effective date, term length, total value, currency, auto-renewal, notice period, and governing law. Each upload gets its own row, so when a contract is re-uploaded after a redline, the panel shows the new version alongside the old one with percentage deltas on the numbers that moved.

The schema is opinionated but pragmatic - seven columns that cover most of what reviewers flag at a glance, with money stored in minor units so it can be charted later (no chart ships yet). Extraction runs in the background so uploads stay fast. The trade-off: failures are silent, and the delta math is fragile when a field flips from blank to filled, so anyone importing this should plan to harden the edges.

So what Anyone building contract-review tooling should look here - it's a clean answer to "what do you actually want to see when a contract lands on your desk?"

commit body - New contract_facts table tracks effective_date, term_months, total_value (in minor units), currency, auto_renew, notice_days, governing_law per document version. Re-uploads/renewals add new rows so changes can be charted later. - New lib/contractFacts.ts: maybeExtractContractFacts() runs an LLM call on uploaded text and inserts a row keyed to the doc's current version. Fires fire-and-forget alongside counterparty extraction; never blocks. - GET /projects/:id/facts returns rows sorted newest-first. - New KeyTermsPanel on the project documents tab (collapsible, default open) renders the rows as a compact table with formatted money/term/dates.
