D3: :492 (Severity carries disposition intent) and :460 (the input-cap
asymmetry) are the two limits that can only be closed by changing an
exported symbol. Both now say 'conceded for 1.x', with the 2.0.0
consequence spelled out, instead of 'deferred deliberately'.
D5: :88's 'a calibration fix is pending' is gone. The concession is
narrower than the other two -- no fix is promised, but it is calibration,
so one may land in any 1.x release without breaking the contract.
SECURITY.md carries the part an outsider acts on: the support window is
rewritten off 'pre-1.0', the freeze is stated as a promise about the
Python surface and explicitly NOT about detection behaviour, and the two
permanent concessions join the documented-boundaries list.
