When Kronos freezes a quantity, it commits only to one thing: that the value will not change silently. A frozen number can still be withdrawn when better analysis requires it — but the withdrawal is dated, reasoned, and every document carrying the old value is swept.
The freeze mechanism has teeth and has been exercised: of fourteen quantities frozen in one round, three were withdrawn and two restated within hours, each because it rested on a basis the freeze itself superseded. The remaining values stand, each re-verified from its source before freezing.
A freeze that permits recorded withdrawal is stronger, not weaker, than one that pretends permanence. It lets the programme commit to consistency while staying correctable — the opposite of the silent design drift that produces a machine no single analysis ever checked.
| Freeze means | no silent change |
| Withdrawal | dated, reasoned, documents swept |
| Exercised | 3 withdrawn, 2 restated of 14 in one round |
| Standing values | re-verified from source |
| Prevents | silent design drift |
