S3-080: Complete both Amazon campaign paths

Parent and ownership

Parent epic: https://github.com/stacksjs/the-settlers-iii-remake/issues/12 Source owner: stacksjs/the-settlers-iii-remake. Master roadmap: https://github.com/stacksjs/the-settlers-iii-remake/issues/4.

Problem and observable result

Adapt both original campaign perspectives. Match conditions, briefings, and outcomes. Retain per-mission branch evidence.

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

Decoded mission data drives a bounded declarative objective runtime. Save mission progress with the world. Editing and import/export use the same validated map representation.

• https://github.com/paulwedeck/settlers-remake/blob/6ad8c4230a4aa4cd21840f8cb59a38344e41c3e0/jsettlers.logic/src/main/java/jsettlers/logic/map/loading/original/OriginalMapFileContentReader.java

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

• Adapt both original campaign perspectives.
• Match conditions, briefings, and outcomes.
• Retain per-mission branch evidence.
• 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.
• Include a per-mission table covering original identifier, starting state, objectives, special triggers, save/load, failure, victory, and retained evidence. A generic victory is insufficient.

Test matrix

• Run both complete campaign paths.
• Verify distinct objectives and progression.
• 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.

Per-mission acceptance ledger

These are planning slots. Original file identifiers, revisions, names, starting conditions, objectives, timings, and evidence are unverified until S3-002/006/007 establish them. Reconcile counts and add any missing original missions before closing this issue. Do not convert an unchecked cell into a passing result without a retained fixture and receipt.

The preserved original manual identifies the tutorial, base factions, Mission CD, Amazons and Three Gods paths. The campaign index supplies the provisional eight-mission and twelve-mission slot counts; it is secondary evidence, not authority for mission behavior.

For every row, record the original map ID/hash and rules revision; starting players, terrain, goods and units; exact objectives/triggers and failure conditions; briefing, voice/cinematic and localization; checkpoint restoration mid-trigger; victory, unlocks/branches and ending; and links to original observation plus browser/native captures.

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.
