thethreemagi 504538567f roster: households, scouts, a per-year checklist, lead import 
Decided by Mike 2026-09-04. my.scouting stays the record of registration;
this holds what a den leader needs on a Tuesday: the families, which scout
is in which den, and a per-program-year checklist of things collected -
dues paid, health form handed in - recording THAT a thing was collected,
by whom and when, never the thing. Health forms are never stored here;
that is a policy, not a gap. A scout is a first name, last name, unit,
den and an optional BSA member ID (the recharter join key), and nothing
else: no date of birth, no address, nothing medical, and a test asserts
no such column exists.

A join lead can be imported as a household: contact copied, the children
field carried as a note to sort by hand, the lead linked and untouched.
Importing twice is 409.

roster:write for leader and above, never on a script key. Every write
lands in the action log. scout-website-backup.timer already copies the
database nightly, which was the doc's first condition for naming scouts.

identity.py - units, people, roles, invites and sessions for greenlanescouts73.org
This is the identity layer the leader console (scout-control) and the member
document gate both sit on. It owns tables in scout73.db and, like store.py,
this app remains the only writer to them.
Three decisions are load-bearing and should not be quietly undone.
UNITS ARE A TABLE, NOT A STRING. A slug typed into six places is a slug that
will be typed wrong in one of them. Meeting nights live on the unit row rather
than in settings, because they are facts about a unit, and they are stored
structured (weekday + 24h time) rather than as display sentences, because the
site composes them five different ways.
ROLES SPLIT TWO WAYS. `leader` and `member` are per unit, in memberships.
`owner` and `admin` are site-wide, in people.global_role. If admin were a
membership row, granting it would mean one insert per unit, and the day a third
unit is added every existing admin would silently lose sight of it. Effective
capability is the union of the global set and the per-unit sets.
NOTHING IS HARD DELETED. People are disabled, invites are revoked or consumed,
sessions are revoked. Who had access, and when, has to stay answerable.
Stdlib only, as with store.py - scrypt ships with Python, so this adds no
image dependencies.
