1 """Add symbol vitals + coupling tables; add message/commit_branch to history entries.
2
3 Pre-computes coupling and symbol vitals at push time so the symbol detail
4 page is a set of simple indexed reads instead of expensive aggregations.
5
6 New tables:
7 musehub_symbol_vitals — first_introduced, change_count, version_count, op breakdown
8 musehub_symbol_coupling — (address, co_address, shared_commits)
9
10 New columns on musehub_symbol_history_entries:
11 message — commit message (denormalized from musehub_commits)
12 commit_branch — branch the commit landed on
13
14 Revision ID: 0031
15 Revises: 0030
