Weekly per-MP voting-cohesion signals for Canada's House of Commons (session 45-1): each week the keyless openparliament.ca API is swept for every recorded division, all ballots, and each MP's vote-time party, riding and province. Party positions are RECOMPUTED from cast ballots and cross-checked against openparliament's own per-party disagreement figures (fail-loud on any mismatch; a disagreement-only mismatch is kept only when it reconciles as a verified upstream phantom (for example vote 45-1/3) and is logged loudly); ballot totals are verified against each vote's official yea/nay/paired totals. Per MP the panel carries ballots cast/paired/absent, ballots with party, rebellions, cohesion_rate (with-party / cast), a documented 0-100 cohesion_score, cohesion_rank, maverick_flag (cohesion < 0.95), and party unity rates/ranks; individual ballot rows are NOT stored. Who joins this: a political-risk desk joins per-MP cohesion to its legislator watchlist on mp_slug + as_of; a newsroom joins maverick_flag + party_unity_rank to whip-count coverage. Primary key (as_of, mp_slug); join keys mp_slug, mp_name, party, riding, province, as_of, country_code (CAN). Cohesion is null for MPs with zero cast ballots (for example the Speaker, who votes only to break ties); exact-tie 'Split' votes are excluded from cohesion; cohesion is a within-session relative measure, not comparable across parliaments.

Column	Type	Description
as_of	string	Snapshot date (UTC, YYYY-MM-DD). Part of the primary key. (unit: date)
session	string	Parliamentary session covered (45-1: 45th Parliament, 1st session). (unit: text)
mp_slug	string	URL-safe MP identifier from openparliament.ca. Primary-key part; the join key. (unit: text)
mp_name	string	MP display name as published by openparliament.ca. (unit: text)
party	string	MP's latest party short name (Conservative, Liberal, Bloc, NDP, Green). (unit: category)
riding	string	Federal electoral district (latest membership). (unit: text)
province	string	Province/territory code of the riding (e.g. ON, QC, AB). (unit: text)
country_code	string	Always CAN (ISO alpha-3). (unit: ISO alpha-3)
n_votes_in_session	integer	Recorded divisions collected for the session in this snapshot. (unit: count)
n_cast	integer	Yes/No ballots cast by the MP (Paired and Didn't vote excluded). (unit: count)
n_paired	integer	Paired ballots: arranged abstention, excluded from cohesion. (unit: count)
n_absent	integer	Divisions where the MP is recorded as Didn't vote. (unit: count)
n_with_party	integer	Cast ballots matching the vote-time party majority (split votes excluded). (unit: count)
n_rebellions	integer	Cast ballots against the vote-time party majority position. (unit: count)
cohesion_rate	float	n_with_party / n_cast; null when n_cast = 0 (e.g. the Speaker). (unit: share)
cohesion_score	float	Documented 0-100 rescaling of cohesion_rate; null when n_cast = 0. (unit: score)
cohesion_rank	integer	Rank by cohesion_rate desc, 1 = most cohesive; ties: n_cast desc, name asc. (unit: rank)
maverick_flag	float	1 when cohesion_rate < 0.95 (documented); null when n_cast = 0. (unit: flag)
party_unity_rate	float	Mean cohesion_rate over the party's MPs with n_cast > 0. (unit: share)
party_unity_rank	integer	Party rank by party_unity_rate desc (1 = most unified). (unit: rank)
vote_numbers	string	Sorted comma-joined division numbers where the MP cast Yes/No. (unit: text)
row_hash	string	Deterministic 16-hex hash over (as_of, mp_slug, n_cast, n_with_party, vote_numbers). (unit: hash)
