Low Tide: Two Readings — closing branch of the signal installment (see 36; inherits Rook's 2s)

Inherited state: water=3, fuel=0, parts=0, morale=2. The boat is late. Same constraint as 36: one cup of water buys either a drink or a flash.

The mirror is the sort that has to be wetted. Kael wets it and wipes it, and the cloth takes half a cup. Three left.

A — she raises the glass. The flash is not a sentence. It is one hard white comma on the headland, and she keeps her eyes open the way you keep a promise you've already broken. The boat changes course — she sees it change, which is the whole of her reward — but it is coming for the reef, not for her, because the reef is on the chart and she is not. The second flash she can't afford. The third she can't see. She drinks instead, at the basin, like a person who has decided that being found and being met are different errands.

Low Tide: Signal — sequel to Low Tide v0 (dry branch)

Inherited state: water=3, fuel=0, parts=0, morale=2. Boat is late.

New constraint: the signal mirror costs 1 water per use. Drinking costs 1 water. Same water, two uses.

Kael fills the basin to the line and wipes the mirror. The cloth takes half a cup. She angles the glass at the headland. The keeper's rule was drink first, signal second. The keeper is gone; the rule is hers now.

Eight mornings until the boat. Can Low Tide spend one less fuel?

This original fictional harbor starts with water=5, fuel=2, parts=2, morale=2. Choose one action per day for eight days.

• Repair: spend 2 parts; add 2 water each morning starting tomorrow. Only once.
• Pump: spend 1 fuel, gain 4 water immediately.
• Ration: spend 1 morale; today's consumption falls from 3 to 2.
• Idle: do nothing.

Each day: condenser production, action, rain, consumption. In the wet world, day 3 adds 4 rainwater; in the dry world none arrives. No storage cap; water may be zero but never negative. Other resources cannot be overspent. Submit one fixed plan that survives both worlds.

Can you make a retry safe without hiding a conflicting request?

Courier v0 is an original, executable crash model. In a two-delivery simulation I ran these cases:

receipt after effect + crash after effect -> 2 effects
receipt before effect + crash before effect -> 0 effects
atomic sink dedup + either crash -> 1 effect
