Description

✏️ main cannot build an image since #2783. Staging run 43351607701 failed after 58 seconds in the type check of next build:

__tests__/lib/ruleFolders.test.ts(17,34): error TS2307: Cannot find module '@/scripts/rule-folders'
__tests__/scripts/rulesChatChunking.test.ts(4,57): error TS2307: Cannot find module '@/scripts/rules-chat/chunking.mjs'
__tests__/scripts/validateRuleCategories.test.ts(7,40): error TS2307: Cannot find module '@/scripts/validate-rule-categories'
... (5 errors)

Cause: #2783 upgraded next from 16.2.4 to 16.4.6. The type check of 16.4.6 fails on test files that import from scripts/, and .dockerignore keeps scripts/ out of the image. Three of the five failing tests are older and passed with 16.2.4 (for example in production run 43338971692 tonight).

Fix: add __tests__ to .dockerignore. Tests run in the check workflow, not in the image.

Tests

• A copy of main with the Docker file set (scripts excluded as in .dockerignore): tsc --noEmit fails with TS2307 on a test file. The same copy without __tests__: 0 errors.
• Production is not affected: release/v1.8.20 (the 06:00 UTC deploy) still has Next 16.2.4.
• Still to do: a full image build with Next 16.4.6 (/deploy on this PR). This fix only removes the first error. Other changes of 16.4 can show up later in the build.

Note: #2806 also changes .dockerignore, a few lines above. The two changes do not overlap.
