Tunnels

IP-in-IP, GRE, and IPv6 transition tunnels. The RFCs whose summary names the tunnels aggregate, with their mandatory and optional coverage.

Mandatory3.3%2 of 61 (3.3%)

MUST, MUST NOT, REQUIRED, SHALL and SHALL NOT rows of the walked RFCs that a recorded test break proves.

Optional0.0%0 of 64 (0.0%)

MAY, NOT RECOMMENDED, OPTIONAL, RECOMMENDED, SHOULD and SHOULD NOT rows, counted the same way.

Mandatory ceiling3.3%2 of 61 (3.3%); excluded: Not applicable (classification can be revisited): 59 of 61 (96.7%)

Attainable mandatory rows under current classifications, over the unchanged total.

Optional ceiling100.0%64 of 64 (100.0%)

Attainable optional rows under current classifications, over the unchanged total.

Not walked0of 5 RFCs

RFCs with no valid extraction sign-off: their rows count in neither figure.

Mandatory registernot completeevery row proven, none unwalked

A profile is complete only when it requires at least one RFC and none of them is unwalked.

Mandatory ceiling: 2 of 61 (3.3%); excluded: Not applicable (classification can be revisited): 59 of 61 (96.7%). Optional ceiling: 64 of 64 (100.0%). Lowest mandatory ceiling: rfc2003 0 of 13 (0.0%). Lowest optional ceiling: rfc2003 24 of 24 (100.0%). Ceilings describe current classifications, not an immutable Linux maximum. Not-applicable and feature-declined classifications can be revisited. Every gap remains work Ze owes.

Tree

Roots first: an RFC sits one level above the highest level of the RFCs it builds on, and the RFCs of one citation cycle share a level. Each bar is the share of that figure's rows a recorded break proves; the ceiling below it shows attainable rows under current classifications. An RFC that is not walked shows an empty bar and no figure or ceiling.
