Michal 5ed0e4888a labsim: both matrices green end to end, numbers reproduced ...

Final confirming run with GRACE=300 and every fix installed:

  --all   ALL PASS  (T0 T3 T5 T8 T11 T12)
  --hard  ALL PASS  (replace / deny / disable, each policy verified)

Second independent measurement of the hard failover, which is what makes the
figures trustworthy rather than anecdotal:

                run 1   run 2
  replace        26s     26s
  deny          148s    141s
  disable        21s     20s

`deny` sits at ~141-148s across both, so it is the AC's dead-peer behaviour
and not a one-off; GRACE=300 keeps roughly 2x margin.

Corrected an overclaim in PPPOE-HA.md while confirming it: the invariant row
read "AC never showed two simdsl sessions", and under session-control=disable
it did -- one live, one orphaned from the destroyed router. Only ever one LIVE
router dialled, which is the invariant that matters. Said so plainly rather
than leaving a table that reads better than the evidence.
