The maintainer asked for a rule for what the budget is FOR: main spend on
the task at hand, some on control, review and improvement, 80/20 to
start, adjustable by phase.
META-25 has a threshold and no stated purpose, which is why the number
has been argued three times. The purpose goes first.
Recorded in the task: the ratio and the window are a pair. Over a
trailing 3-pass window one meta pass at parity cost is already 33%, so a
20% line there means 'one in five AND half price' rather than 'one in
five'. Over trailing 5, 20% is exactly one pass in five at normal cost,
which is the literal reading of the instruction.
The phase adjustment must be declared, argued and expiring in the shape
gates.toml already uses -- a threshold anyone may move is not a
threshold, and this project fixes limits structurally rather than
raising them.
