jpmschweitzerandClaude 474ab90663 feat(ui): rivers as cartographic strokes (D-261, T-1237)
Rivers now appear on the whole-body map for the first time. Five on Ferrath's
Global canvas, drawn as 5 px strokes that stop at the coastline.

Four rules, all client-side over existing server data, computed once on canvas
adoption rather than per draw:

  - fixed 5 px screen-space stroke at every rung
  - contiguous geometry through the river's own cells
  - never drawn over water — ocean and lake end a run
  - culled below 15 px of on-screen length (3x the stroke: below that a line
    is a square, not a river)

TWO THINGS THE MEASUREMENT FOUND THAT THE RECORD DID NOT ANTICIPATE.

First, the cull unit was wrong. A server "course" is an EDGE of the river
network — the stretch between two confluences — not a river. Culling per
course culls per segment, so a long river assembled from many short edges
vanishes entirely. Measured on Ferrath Global: 375 courses, 180 surviving the
water clip, and ZERO surviving a per-course cull. Edges are now chained
end-to-end into rivers before the cull is applied, which also delivers the
other half of D-261's "contiguous": per-course contiguity only makes each edge
unbroken; joining is what makes a river read as one line rather than dashes.
After chaining, 5 rivers survive at Global — the "major systems only from
orbit" behaviour the record predicted, arrived at by a different route.

Second, and worse: uses_orbital_derive() still read `Global | Region` while
the client's mirror had said Global-only since 2026-07-26. The D-255 amendment
claims "Region left the orbital derive set... it now takes the full
courses-aware derive". That was implemented against the MIRROR and never
against the authority, so Region kept running envelope-only and carrying no
courses — the exact thing the amendment said it had stopped doing. Both test
suites stayed green for two days because neither compares itself to the other.
Fixed here, with a note on each side pointing at the other, since the two
cannot be cross-checked automatically.

Also removes the two gates that withheld courses from the orbital rung — the
reason the whole-body map had no rivers at all. Whether a course is worth
drawing is measured in screen pixels, which only the client knows, so the
server now supplies geometry at every rung and the client decides.

The capture harness reports "drawn" alongside "courses", because "375 courses
arrived" and "375 rivers are drawn" are different claims and conflating them
is what made an empty map look like a data problem.

Client suite 1836 / 1810 passed / 26 skipped. Server suite green.

The Settled Reach

A top-down immersive sim where you only know what you can see, hear, and prove.


You're not the hero. You're a witness with a gun.

Pick a character. Step into their life. Figure out what's happening before it's too late.

The Settled Reach is a single-character detective game where information is the real weapon. You play from one perspective in a simulated world full of people who lie, withhold, and reveal on their own schedules. What you know depends on where you are, who you trust, and whether you're asking the right questions.


What You Do

Investigate. Follow leads through a city you can't see all at once. Line-of-sight isn't a gameplay abstraction - it's the core mechanic. You see what your character sees. Walls block vision. Corners hide threats. Fog returns when you leave. Information decays.

Navigate. Your neural lattice gives you directions, but only to places you've learned about. Contacts send locations. Research reveals addresses. Physical exploration fills the gaps. The map is sparse and frightening at first. By the end, you realize how much you missed.

Decide. Every conversation is a negotiation over what gets shared. NPCs have their own goals, their own information, and their own reasons to lie. You choose who to trust based on incomplete data. Sometimes you're wrong.

Act. When investigation fails, violence is an option. Fights are tactical, asymmetric, and often a terrible idea. Power mismatches run in both directions. Death costs you everything since your last backup - lost knowledge, lost relationships, lost deals. The world knows what you forgot.

Survive. An AI storyteller paces events for dramatic tension. The conspiracy's structure is set at game start. When things happen is driven by how you're doing. Comfortable? Something breaks. Desperate? A break appears. The game wants a story, not a grind.


Core Features

Information Asymmetry as Master Mechanic

You only know what your character knows. The same world looks completely different from different perspectives. A Senator sees political venues on their map. A Guardian sees safehouses. Same conspiracy, different game.

Occlusion-Based Detection

Vision is line-of-sight with a directional cone. You see what's in front of you. Peripheral vision is reduced. Behind you is fog. Sound gives partial information outside your view - footsteps, voices, gunfire. You make decisions based on what you can piece together.

Internal Monologue

Your character interprets what they sense in their own voice. Footsteps behind you. Thermal signatures through walls. A contact's nervous tells. The monologue bridges what the camera can't show and creates atmosphere. It can also be wrong.

Perception Modes

Different characters access different sensors. Natural vision shows detail but is blocked by walls. Thermal imaging shows heat signatures with no identity. Camera feeds give remote vision but can be spoofed. Unisphere tracking pings known contacts but can be masked. Each mode reveals different information with different trust tradeoffs.

Diegetic Interface

The map is your character's neural lattice - Settled Reach technology, not a game UI. Points of interest appear when you learn them through gameplay. Tips can be traps. Navigation is pulled by player intent, not pushed by map design.

Multiple Playable Characters

Every character starts in a different position with different knowledge and different tools. A cop has case files and legal authority. An investigator has contacts and freedom to operate. A politician has institutional access and public constraints. Replayability comes from perspective, not randomness.

Rimworld-Style Storyteller

Events emerge from simulation, paced by an AI director. No timers. No scripts. Consequences of what's already in motion. The storyteller knows what you've lost and can exploit it.

Wildly Asymmetric Combat

Balanced fights are the exception. You're outgunned or overpowered, rarely evenly matched. Tactical clarity from the top-down view. Z-levels create verticality - fights across floors of a building. Perception boundaries mean you can be ambushed. Victory often means not fighting at all.


The Setting

Humanity spread across hundreds of star systems by learning to activate alien gates it didn't build. The result is the Settled Reach - a civilization stitched together by infrastructure it doesn't fully understand.

You live in a society where death is temporary (if you can afford the backup), enhancement is political (who gets augmented and why), and the gates that connect everything were made by someone who hasn't introduced themselves.

Wormholes aren't fast travel markers. They're physical locations you traverse. Social chokepoints. Surveillance points. The infrastructure you depend on to move between worlds.

Something is breaking. Or something is waking up. You're in the wrong place at the right time to figure out which.


Built For Replayability

Structural randomness set at game start: who's compromised, where evidence is hidden, which contacts can be trusted. Play the same scenario as different characters and encounter a different game. The conspiracy's skeleton is fixed. The flesh changes every time.


Development Philosophy

Single-character perspective. Asymmetric information as core mechanic. Top-down camera locked to character position. Godot 4 client + Rust simulation server. Client-server architecture from day one, designed for multiplayer even though single-player ships first.

No fog-of-war as an afterthought. No tutorial popups. No omniscient map reveals. The game is built around what you don't know.
