  As the nearest confirmed Lyman continuum (LyC) emitter, Haro 11 is an
exceptional laboratory for studying LyC escape processes crucial to cosmic
reionization. Our new HST/COS G130M/1055 observations of its three star-forming
knots now reveal that the observed LyC originates in Knots B and C, with $903 -
912~\r{A}$ luminosities of $1.9\pm1.5 \times 10^{40}~\rm erg~s^{-1}$ and
$0.9\pm0.7 \times 10^{40}~\rm erg~s^{-1}$, respectively. We derive local escape
fractions $f_{\rm{esc, 912}} = 3.4\pm2.9\%$ and $5.1\pm4.3\%$ for Knots B and
C, respectively. Our Starburst99 modeling shows dominant populations on the
order of $\sim1-4$ Myr and $1-2\times10^7 \rm~M_\odot$ in each knot, with the
youngest population in Knot B. Thus, the knot with the strongest LyC detection
has the highest LyC production. However, LyC escape is likely less efficient in
Knot B than in Knot C due to higher neutral gas covering. Our results therefore
stress the importance of the intrinsic ionizing luminosity, and not just the
escape fraction, for LyC detection. Similarly, the Ly$\alpha$ escape fraction
does not consistently correlate with LyC flux, nor do narrow Ly$\alpha$ red
peaks. High observed Ly$\alpha$ luminosity and low Ly$\alpha$ peak velocity
separation, however, do correlate with higher LyC escape. Another insight comes
from the undetected Knot A, which drives the Green Pea properties of Haro 11.
Its density-bounded conditions suggest highly anisotropic LyC escape. Finally,
both of the LyC-leaking Knots, B and C, host ultra-luminous X-ray sources
(ULXs). While stars strongly dominate over the ULXs in LyC emission, this
intriguing coincidence underscores the importance of unveiling the role of
accretors in LyC escape and reionization.
