+# BUILD PR — Games Space Invaders Copy From Next
+
+## Purpose
+Copy the validated `_next` candidate into the canonical destination `games/SpaceInvaders/**`.
+
+## Context
+- `games/SpaceInvaders/**` has been cleared
+- `games/SpaceInvaders_next/**` contains the migrated, runnable candidate
+
+## Single PR Purpose
+Perform a clean copy from `_next` to canonical, preserving structure and ensuring required files are present.
+
+## Source / Destination
+Source:
+- `games/SpaceInvaders_next/**`
+
+Destination:
+- `games/SpaceInvaders/**`
+
+## Scope (STRICT)
+- Copy all files and folders from `_next` into canonical destination
+- Preserve exact structure
+- Ensure runtime works from canonical path
+- Validate presence of required files (including capture-preview.html if present in source)
+
+## Required Validation Rule
+- If `capture-preview.html` exists in source:
+  → it MUST exist in destination
+- If it does NOT exist in source:
+  → DO NOT create it
+  → DO NOT guess content
+  → proceed without it
+
+## Allowed Operations
+- copy files/folders
+- adjust relative paths ONLY if required for canonical runtime
+- ensure index.html boots correctly
+
+## Explicit Non-Goals
+- DO NOT modify `_next`
+- DO NOT recreate missing files
+- DO NOT refactor engine/shared
+- DO NOT change other games
+
+## Fail-Fast Conditions
+STOP if:
+- source `_next` is missing required runtime files
+- copy would require guessing missing files
+- runtime cannot work post-copy without structural changes
+
+## Acceptance Criteria
+- `games/SpaceInvaders/**` matches `_next`
+- game boots from canonical path
+- no console errors
+- `_next` remains unchanged
+- capture-preview.html rule respected
+
+## Validation Steps
+1. Open `games/SpaceInvaders/index.html`
+2. Confirm gameplay runs
+3. Confirm no console errors
+4. Compare structure with `_next`
+5. Verify capture-preview.html handling
+
+## Output Requirement
+Codex must package:
+`<project folder>/tmp/BUILD_PR_GAMES_SPACE_INVADERS_COPY_FROM_NEXT_delta.zip`
