backend/thesis_seed.py builds the starting "living messaging source of truth"
from docs/thesis-seed-v5.md: a core line (throughline; the open Option A/B banner
as a competing variant group; the three pillars; the proof; voice rules), one line
per LP segment carrying that segment's angle, and the five segment definitions.
ensure_thesis_seed(conn) runs from init_db, seeding ONLY when the Workshop is empty
(no thesis lines) — idempotent and non-destructive, so it bootstraps once and never
overwrites partner edits. Everything lands draft/candidate; nothing is made canonical
(that stays the partners' dual-approval action, guardrail #4). Content is Ten31's own
messaging, not LP data.
Test: backend/test_thesis_seed.py runs init_db and asserts the core line, 5 segment
lines, the 2-member Option A/B variant group, 3 pillars, segment_cuts, and segment
defs, plus re-seed-is-a-no-op (11/11).
