jschoubben 77a1493df4 Renumber to 0116: another record took 0115 on main
PR #133 landed a different 0115 while this branch was open. The bus record
is now 0116, with every citation in designs 19, 25, 28 and the index
following it.

Note: cycle.py and records.py both fail on main as merged, on that record —
nothing cites it, and it rests on 0112, which is still proposed. Both
pre-date this branch and are left for their own change.

jschoubben 1c808898a5 Allow progressive insight, and apply two to the bus record
A record can assert a fact that goes stale while the decision it supports
stays right. Superseding for that buries a sound record under a second one
and makes every reader work out which is live. So a correction of fact is
now made in place, marked and dated, with the old wording quoted — bounded
by three conditions and checked by records.py, which fires on an unmarked,
undated or back-dated note. Judgements still supersede.

Applied to 0115: no conformance suite exists to recapture, and the full
genesis bed cannot run until the links exist. Designs 25 and 28 follow.

jschoubben 6ab113e6c6 Break the bus work down, measured, in dependency order
Counting the surface first changed the plan twice: the genesis bed cannot run
until the links exist, so it belongs to step 4, and there is no conformance
suite to recapture — step 3 builds one against the current bus before moving
it. Both corrections are recorded in the breakdown rather than edited into
ADR 0115. Also indexes design 25, which was never listed.

jschoubben fe0c1e9da2 Divide the bus work into five steps, each proved on its own
The NATS change was recorded as one undivided item, which hid three gaps:
a mesh already running had no adoption path, the protocol specification did
not know its transport was being replaced, and nothing was runnable until
everything was. Dividing it is what surfaced them.
