Unity publication — 12 October 2026

This update publishes the current ECHO-Station 1.0 and the separate Echo MMO Prototype BETA 0.0.2 project under WorldPrototype/. The live working projects and their running services were left untouched. The ECHO brain remains an imported dependency from the official echoai repository, checked at commit f6062de0462a523296eb2cbb704472f4faa4a022.

What is included

Station, NavigationLab and ArachnidLab; C# world/motor/sensor/HUD sources; original eight-legged arachnid prefab, Blender source, FBX, GLB and export ZIP; Python bridge with E[6], persistent/revisable CAM, causal web inspector and tests; resource/offline/conditioning/closure tools; documentation, captures and the original experiment records, including failed development attempts.

WorldPrototype includes its independent Assets, Packages, ProjectSettings, tools, documentation, original historical screenshots and explicitly licensed textures. It is a local playable prototype, not a working multiplayer MMO or an ECHO NPC experiment. Unverified atlases have documented visual fallbacks.

The October 12 evidence archive retains full JSON/JSONL transcripts and original SHA-256 chains. Unlike the earlier bounded selection, it also includes the CPU navigation transcript campaigns and Unity-specific frozen source snapshots. Historical dependency hash lists are preserved; copied ECHO core implementations are excluded. Archive contents and limits.

Public-copy offline CPU mission and resource threshold	Passed
Public-copy development journals	18/18 audited
Earlier archive checks	50 hashes, 10 chains, 152 physical plan replays and 23 tamper tests passed
Archive relocation checks	21 tests, including tampering, missing files and namespace escapes
Separate WorldPrototype development verification	52/52

This new development pipeline used system Python 3.14.6, the public sibling ECHO checkout and only the portable publication project. It ended with valid: true, development_only: true. It deliberately did not open a new confirmation or tune against the original held-out maps. The original 16/16 confirmation remains the historical result described in the closure report. The fresh physical run tests the changed public scene rather than relying on compilation alone. The WorldPrototype screenshots are historical; the new check is a headless development verification, not a new graphical review.

Run Tools/check_publication.py to verify the final distribution manifest, all original October 12 archive hashes and all 34 original closure journals. Source hashes are exact for this export; historical frozen manifests are exact for their original run. They intentionally describe different scopes.

Publication corrections

Reused the existing sibling-source importer. New CAM/WSP/QN imports use the official echoai.core implementation through echo5.legacy, preserving module identity. No alternate CAM, thought bus or LLM was introduced.
Launchers and checks use the selected Python interpreter, UNITY_EDITOR or Unity on PATH, and optional BLENDER_EDITOR. They no longer require the author's home paths or private virtual environment.
Station launches through port 8771; the historical NavigationLab remains on
1. The public scene now has the arachnid body and basal telemetry.
Fixed 17 out-of-range placeholder renderer identifiers inherited from the earlier public scene. Unity had rejected them as duplicated identifiers and could not resolve the robot. Unique signed-64-bit IDs preserve the existing props/colliders. World checks and all three physical missions now pass.
Added strict relocation to the arachnid auditor: original paths are mapped into a supplied archive, without falling back to the live original tree. Hashes and receipt checks are unchanged; archived evidence is never rewritten.
Added publication source/archive verification, screenshots with provenance, current README/setup instructions and per-project license notices.

Exclusions

No Library/Temp/build cache, browser profile, credentials, private agent configuration, raw Unity licensing log, crash dump or private game save is published. Adventure Forge source graphics and standalone atlases without confirmed redistribution terms remain local. The original arachnid is CC0; other source is GPL-3.0-or-later, and redistributable textures retain their provided CC licenses. NOTICE.

Publication does not change the scientific policy, certify general-purpose intelligence or reopen S6. ECHO-Station's measured contract and the game's unfinished feature set are documented independently.
