Hi Clement,
The strong link (shown in red above) is not guaranteed because there's yet another 6-digit at r9c9 having undetermined parity.

Yep, it seems to require a bit longer chain:

(9)r9c9 = (9-6)r9c6 = r8c6 - r8c8 = r6c8 - r5c7 = r5c1 - (6=259)r7c143 => -9 r7c79; stte

I'm already slipping, but since I couldn't yet leave due to an unfinished discussion, and already used this puzzle as an example in it, I might as well post my solution too. I'm surprised it's still available anyway.

UR(25)r79c14 using #externals (b7)

(6,2)r8c81 == (526)r7c341 => -6 r7c79,r8c1; stte

or:

(6,2)r8c81 == (597)r7c379 => -6 r7c79; stte

variants with internals, some of them quite funny: Show
UR(25)r79c14 using +internals

(6)r7c1 == (369,2)r9c1269 - (2=6)r8c8 => -6 r7c79,r8c1

(6)r7c1 == (3|6-52)r9c14 = (26)b9p95 => -6 r7c79,r8c1

(6)r7c1 == (3|6-5|2)r9c1 = (52)r9c49 - (2=6)r8c8 => -6 r7c79,r8c1

(6)r7c1 == (3|6-5|2)r9c1 = (52-9)r9c49 = (97)r7c79 => -6 r7c79
