-- Migration 011: flip auto_summarize default to TRUE (ADR-018, Future-B).
--
-- Scheduled discovery (ADR-018) makes Tapir watch unprompted. For onboarded
-- friends that only delivers zero-friction value if the list also SUMMARIZES
-- itself — a manual default would mean the scheduler discovers videos a user
-- still has to click through one by one, which is the empty-list problem again.
-- So new users default to AUTO. The account-page toggle still lets a user switch
-- to manual (SetAutoSummarize), so this only changes the out-of-the-box state.
--
-- Safe only because the process-wide caption-fetch rate gate (ADR-014 item 2)
-- now exists: auto + scheduled + multi-user would otherwise self-inflict 429s
-- every cycle. The gate is the precondition for shipping this default.
ALTER TABLE users ALTER COLUMN auto_summarize SET DEFAULT TRUE;

-- Bring existing rows (maintainer + any current registrations) onto the new
-- default so they benefit immediately, not just users created after this point.
UPDATE users SET auto_summarize = TRUE WHERE auto_summarize = FALSE;
