Subject: [PATCH 01/66] Add failing tests for ical generation with nil event
 data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Tests exercise icalendar_proposals with nil event_type, nil time,
and nil room — all of which currently raise NoMethodError.

Subject: [PATCH 21/66] Fix registration form not displaying validation errors

The sign-up form silently fails when validation errors occur (e.g.,
duplicate username, password too short, password mismatch) because
the Devise registration views never render resource.errors.

Add error message rendering to the _form_fields partial so users
see clear feedback when registration fails.

Fixes #61

Subject: [PATCH 25/66] Migrate from Stripe Charges API to Stripe Checkout
 Sessions API

Replace legacy Stripe Charges API with modern Checkout Sessions API. Users are redirected to Stripe-hosted payment page with itemized ticket breakdown, multi-currency support, and session-based payment confirmation. Also fixes registration form error display, payment button layout, and various linter offenses.

Subject: [PATCH 63/66] fix ben demo seed validations

Move conference dates to 2026-10-14/16 so before_end_of_conference passes.
Expand all abstracts past 100 words to satisfy abstract_limit.
Confirm tracks via update_column after create since the AASM confirm
transition requires a submitter; valid_track checks track.confirmed?.
Replace exists? skip with destroy! so re-runs always produce a fresh seed.

Subject: [PATCH 66/66] Force SSO for new sign-ups (closes #64) (#69)

* Force SSO for new sign-ups via environment variable

Add PREVENT_NEW_LOCAL_PASSWORDS env var that hides the local
registration form and shows only Google and Snap! SSO buttons.
Existing users can still sign in with username/password below
the SSO buttons. Local auth code is preserved to avoid upstream
merge conflicts.

* Use button_to for SSO buttons to ensure POST without JS dependency
