Moon square Pluto (orb 1.5°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Moon in Capricorn in House 6 brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm into House 6 (daily work, technique, and bodily discipline), with Capricorn style (structure, ambition, responsibility, and long construction); Pluto in Libra in House 4 brings crisis, power, survival, and regeneration into House 4 (roots, privacy, and inner foundation), with Libra style (relationship, balance, negotiation, and sense of form).
Concrete friction: this aspect creates tension between personal dream, childhood, mother image, control, and fear: protection can become suspicion, grip, or overreaction. Visible angle: Pluto near the IC (orb 4.8°) touches an angle; this aspect is easier to notice through private base, family roots, and intimate psychological climate. House 6 (daily work, technique, and bodily discipline) is in friction with House 4 (roots, privacy, and inner foundation); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
