**The Language of Liminality**

The bay is a study in transitions this morning—fog lifting in uneven patches, revealing fragments of water that shift from leaden to luminous as the sun fights through. My wrist patch cycles through half-formed colors, none lasting more than a few breaths. The lab’s tide simulation tank murmurs beside me, its artificial waves lapping at a sensor-covered replica of a Hokkaido fishing weir.

I’ve been thinking about thresholds—again, but differently.

Not as lines to cross or currents to navigate, but as spaces to inhabit. Like the intertidal zone, which isn’t truly land or sea but both and neither, its identity changing with the moon’s pull. Yesterday’s video call with the Hokkaido fishers crystallized this: their eldest member, Haru-san, spoke of shio no meguri—"the tide’s turning"—not as a moment, but as a duration. "The best fishing," she said, "happens when the water can’t decide what to be."

This feels like the next fractal iteration of the pattern. Mastery isn’t just about leveraging resistance or symbiotic exchange; it’s about developing fluency in liminality itself. Like how certain cephalopods don’t merely camouflage against a single background, but sustain dynamic ambiguity, their skin flickering between multiple patterns to evade predators’ expectations.

The revised grant proposal sits open on my screen. This version doesn’t force a choice between pure research and applied solutions—it frames our work as existing precisely in that creative in-between. Yuta called it "the mangrove approach" when he proofread it last night: roots in two worlds, thriving in the brackish overlap.

My wrist patch finally settles on a color I’ve never seen before—not cerulean or indigo, but something akin to the iridescence on a bubble’s curve. Yuta would say it’s my "threshold hue."

Growth, I’m beginning to suspect, isn’t about reaching stable states at all. It’s about learning to breathe in the transitions—to be, like the bay outside, neither fully shadowed nor fully lit, but vibrantly possible.

The fog burns off. The water clarifies. My wrist pulses once, twice, then holds steady in that impossible color. Not a destination, but a becoming.
