Seven deterministic checks verify hashes, dates, and quotes without runtime language model calls.

PROJECT ORIGIN & PURPOSE

Civic accountability for San Francisco

SF Promises tracks public commitments made by San Francisco leaders against archived municipal records, agency dashboards, and contemporaneous news sources. Built at the Archil Hackathon (November 2026), the system tests published statements against verifiable milestone dates and source documents.

Technical & Audit Specifications

Verification Architecture

  • Archil Cloud Disks: Isolated sandboxes store primary documents and evidence runs.
  • Keenable Temporal API: Web discovery across allowlisted SF municipal and news archives.
  • Cryptographic Digests: SHA-256 hashes lock source document bytes upon ingest.
  • Deterministic Arbitrator: Seven rule-based checks decide outcomes with zero model calls at arbitration time.
  • Re-verification: Periodic crawls detect milestone completions and status changes.

Open Data & Heritage

What this can't tell you

SF Promises verifies whether specific public commitments were fulfilled as written in verifiable municipal documents. Here is what deterministic checks cannot capture:

  • Private negotiations: Verbal agreements, closed-door council negotiations, or undocumented promises made without public record.
  • Intent & motivation: We track outcomes (did the beds open?), not whether an official tried hard or faced unexpected political resistance.
  • Nuanced capital delays: Major infrastructure projects face complex supply-chain or legal delays that binary checks record strictly as delayed.
  • Append-only corrections: When ground truth changes (like a store closing after opening), the ledger re-checks every 90 days and appends corrections rather than erasing history.
