hackathon-techex — Verifiable Scan History

New work for the TechEx Amsterdam Hackathon (cybersecurity track, online build 16–19 Oct 2026), built on top of the existing live EilatSecure scanner — does not modify scan.js or scan_own_domains.py at the repo root, only consumes what they already produce.

Full concept and track status: docs/BUILD_PLAN.md

The gap

A scan today is a one-off JSON blob: nothing proves it wasn't edited after the fact, and comparing two scans of the same site means reading two files by hand. Both are real gaps in a product that's already live.

Quickstart (no network calls, no changes to the live scanner)

cd hackathon-techex
pip install -e ".[dev]"
python run_demo.py     # example data, shaped exactly like the real scanner's output
pytest -q              # 17 tests

from sipa_scan_ledger import ScanLedger, ScanRecord, Finding, diff_scans

ledger = ScanLedger("scan_history.jsonl")
ledger.append(ScanRecord("example.com", "2026-10-16T08:00:00Z",
                          [Finding("high", "No forced HTTPS redirect")]))

Structure

Module	What it does	Status
sipa_scan_ledger/record.py	Fixed schema wrapping the scanner's existing finding format	built, tested
sipa_scan_ledger/chain.py + verify.py	Hash-chained history + tamper check	built, tested
sipa_scan_ledger/diff.py	What changed between two scans of the same target	built, tested
sipa_scan_ledger/adapter.py	Converts scan_own_domains.py's real report shape into ledger entries	built, tested

What's still open (see the plan for skill-matched slots)

• Wire the adapter into a real scheduled run of scan_own_domains.py
• A diff view on the EilatSecure landing page, not just terminal output
• Demo video + lablab.ai submission

Team: solo on this hackathon (the only other teammate on the team page opted out of TechEx Amsterdam specifically) — the tracks above are scoped for anyone who joins, not written assuming they will.
