 # Known Issues
 
-## Environment
-
-### Missing Dependencies
-
-The current development environment is missing critical `devDependencies` (`jsdom`, `playwright`, `fake-indexeddb`), preventing many test suites from running.
-
-- **Affected:** `tests/app/channel-profile-moderation.test.mjs`, `test:dm:unit`, `test:dm:integration`, `test:e2e`, `test:visual`.
-- **Reference:** `issues/test-env-deps.md`
-- **Last checked:** 2026-02-08
-
 ## Tests
 
-### Unit Tests
-
-- `npm run test:unit` generally passes, but `tests/app/channel-profile-moderation.test.mjs` fails due to missing `jsdom`.
-- Timeouts may occur in resource-constrained environments (like CI) when running the full suite serially. CI workflows use sharding (`test:unit:shardX`) to mitigate this. Targeted testing (`test:dm:unit`, `test:dm:integration`) is recommended for local development focus but currently fails due to missing `fake-indexeddb`. (Last checked: 2026-02-08)

 ### Skipped Tests

 ### Visual Regression Tests (`test:visual`)
 
 - **Artifact Retention**: Visual tests are configured to retain screenshots, traces, and videos on failure to assist with debugging. These artifacts can be found in `artifacts/test-results/`.
-- **Note:** `test:visual` currently fails due to missing `@playwright/test`.

-# Test Environment Missing Dependencies
-
-## Problem
-
-The current development environment is missing several `devDependencies` that are listed in `package.json`. This prevents running certain test suites.
-
-## Affected Dependencies
-
-- `jsdom`: Required for `tests/app/channel-profile-moderation.test.mjs`.
-- `fake-indexeddb`: Required for `test:dm:unit` and `test:dm:integration`.
-- `@playwright/test` (and `playwright`): Required for E2E tests (`test:e2e`, `tests/e2e/popover.spec.ts`, etc.) and visual regression tests (`test:visual`).
-
-## Impact
-
-- `npm run test:unit` fails partially (`tests/app/channel-profile-moderation.test.mjs` fails with `ERR_MODULE_NOT_FOUND`).
-- `npm run test:dm:unit` fails completely.
-- `npm run test:dm:integration` fails completely.
-- `npm run test:e2e` fails completely.
-- `npm run test:visual` fails completely.
-
-## Notes
-
-- `npm install` is restricted in this environment, preventing easy re-installation.
-- This issue was verified on 2026-02-08.
