Status

Work in Progress - needs signing and ruleset generation

Review Checklist

• Changes to onboarded.txt are accurate
• The file default.rulesets.TIMESTAMP.gz has been updated, extracting that file and inspecting the contents of the JSON file produces the expected rules
• The ruleset has been verified by modifying the HTTPS Everywhere configuration in a Tor Browser instance pointing to Path Prefix: https://raw.githubusercontent.com/freedomofpress/securedrop-https-everywhere-ruleset/$BRANCH_NAME
• index.html has been updated using ./update_index.sh

Post-Deployment Checklist

• Added/modified onion names have been updated in the SecureDrop Directory

About to add at least one more onion name, so ok to hold off on this unless it's in flight already

(That's it for the time being)

@rocodes Thanks for the clear comms here. I'm going to close and re-submit as a PR by me, for your review, since I've added a few changes, and would like full functional review of the generated rules.
