(4=1) r7c467 - (1) r7c3;
(4=3) r3c347 - (3) r7c3;

Nice !
This puzzle had a lot diverse solutions, including lclste ones, that could be presented as different patterns (AIC or ALS loops, doubly linked ALS's, MSLS).
Phil has spotted the five cells r2c28, r4c248 rank 0 logic.
Mine involves the seven cells r3c347, r7c3467 (also MSLS: same cells, 7 links 27r3, 189r7, 3c3, 4c7, or yzfwsf's MSLS)
There was also this simple solution with basic fishes (three steps ?):
XW(2)r28\c59 => -2 r139c59
XW(7)r28c15 => -7 r139c15
SF(8)r248\c189 => -8 r579c1, r9c8, r79c9; lclste
Presented as MSLS: r2c12589, r4c1248, r6c1, r7c1589: 13 cells, 13 links: 278r28, 58r4, 3r24, 29c1, 9c2; same eliminations as above
Much simpler as a Multifish:
7 Truths: 278r28, 8r4
7 Links: 78c1, 27c5, 8c8, 28c9
same eliminations as above
Thanks, Leren, for that funny puzzle !
