AN-001: Do 2024 mayoral polls overstate the sponsoring candidate? AN-002: Does β survive race × week FE with an independent-only comparator? AN-003: Pre-poll trajectory placebo AN-004: Does peak β shift at the 200k runoff-eligibility cutoff? AN-005: Does β shrink as the election approaches? AN-006: Does β depend on which sponsor route maps to the candidate? AN-007: Does pollster β depend on customer mix?

poll — protocol-level metadata + sponsor classification

Poll-level snapshot, one row per protocol. Carries sponsor-type classification (sponsor_types, poll_is_independent, poll_has_candidate_sponsor), pollster identity (pollster_cnpj, pollster_name, st_pesquisa_propria), institute, sample size, field period, and the race muni/uf. Joined back onto cand_poll by source/assemble/cand_poll.py.
