S3-023: Demonstrate the shared browser and native settlement
Parent and ownership
Parent epic: https://github.com/stacksjs/the-settlers-iii-remake/issues/6
Source owner: stacksjs/the-settlers-iii-remake. Master roadmap: https://github.com/stacksjs/the-settlers-iii-remake/issues/4.
Problem and observable result
Run identical simulation commands on both hosts. Show actual animation and native input. Verify checksums, save/load, and lifecycle.
The current application is a browser prototype. Passing the Riverlands campaign does not establish original-game or native parity. This issue is complete only when its stated behavior has retained evidence.
Evidence and interfaces
Craft owns graphics, native hosting, and platform capabilities. stx owns compilation/reactivity. ts-css owns style semantics. Stacks owns build and release orchestration. The game consumes published contracts.

Pin the inspected revisions and fixture hashes in the implementation evidence. Original-game observations govern rules and timing. JSettlers is implementation evidence, not an authoritative balance specification. Unknown values remain explicitly unverified.
Acceptance criteria
- Run identical simulation commands on both hosts.
- Show actual animation and native input.
- Verify checksums, save/load, and lifecycle.
- The visible result agrees with the underlying simulation or platform state, including failure paths.
- Tests exercise the maintained public interface and retain reproducible fixtures or execution receipts.
Test matrix
- Compare seeded browser/native state hashes.
- Exercise moving entities, checkpoint, and resume.
- Exercise invalid input, cancellation or interruption, and repeated execution where this interface permits them.
- Verify determinism/conservation for simulation changes and resource ownership/disposal for platform changes.
- Run owning-repository lint, relevant type checks and tests. Capture actual native output for native capability claims.
Scope constraints
Implement this behavior as a complete verifiable slice. Do not silently expand into adjacent tickets or substitute simplified gameplay. Keep the shared TypeScript simulation, shared stx signals, and ts-css conventions. Native gameplay and HUD must not depend on a WebView. HomeOS reuse must not introduce a kernel dependency into the game. Existing unrelated edits and authored guidance must be preserved.

Upstream release and adoption
Application behavior belongs here. If a reproduction identifies a framework defect, repair and release its owning source first, update Stacks where affected, then install the verified packages here.
No node_modules edits, copied runtimes, generated-source string patches, fabricated globals, successful no-op implementations, or skipped release gates. Push tested conventional commits as Chris to the owning origin/main without coauthor trailers or force pushes.
Completion evidence
- Implementation commits and relevant upstream issue links.
- Exact checks and results, fixture hashes, and screenshots/native execution evidence where applicable.
- Published package versions, downstream lockfile identity, and release receipts when affected.
- Remaining limitations stated explicitly. Partial work does not close this issue.
