 - **`--today DATE` makes "today" an input.** The tracker read the clock, so its
   answer to "what does today owe" was a fact about when it ran rather than about
   a calendar and a date. Now it can be told, which is what lets a report be
   reproduced, lets a day that has not arrived be asked what it will owe, and
   lets the tests assert on a report at all. (#2, #3)
-- **`--backfill` commits what the plan is short, and nothing else.** A plain
-  `--write` puts the same flat count on every lit day, including the ones
-  already bright — and adding to the busiest of those raises the year's peak,
-  which is the very thing every letter day is measured against. A shortfall
-  cannot do that: `need` is at most the peak already, so one pass finishes the
-  plan and the target does not move. Needs `--repo`, and `--write` to commit.
