Rows carry no earner name, so only the ledger path moves; the tutor copies
its data dir (old rows included). Pre-cutover AUTOMATION (anki quota),
LADDER and the waiver are unchanged. Same minutes, cap, ladder, TUTOR_FROM
and confirmed_on.

AUTOMATION_TUTOR: 1 gaming min per unit (minute), max_units 60; TUTOR_LADDER
automation Rung(1, extra=1), rungs still sum 250 (23:00 / 18:50).
credit_units sums each row's units (ROW_UNITS: tutor detail.minutes, a row
without it = 15); a repeated entry_id pays once at its smallest count; an
invalid minutes field is refused by tutor_match. An all-block day resolves
exactly as 0.7.0.

TUTOR_FROM = 2026-10-10 (the day after the deploy). The automation tutor
keeps confirmed_on=None, so it stays "new".
Ladder floor: a rung comes off the floor only for a pure bonus (no
penalty_from) or an earner whose penalty has started -- the same
_penalised() rule (first_credits -> penalty_start, confirmed_on fail-closed
fallback, penalty_from without first_credits) the gaming base uses. Before
this, a never-credited tutor would have lowered 2026-10-10's floor by its
full 50-minute rung (19:50 -> 19:00) even with first_credits. Maturity can
only raise time: new property test against the 0.6.0 floor formula.
ruff 0.17.0 (dependency-freshness): CPY001 ignored -- personal repo, no
copyright policy.
