 # 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` may time out 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. (Last checked: 2025-02-23)
+
+- `npm run test:unit` generally passes, but `tests/app/channel-profile-moderation.test.mjs` fails due to missing `jsdom`.

 ### Skipped Tests
+
 The following tests are skipped due to flakiness or environmental issues and should be investigated:
 
-- `tests/e2e/popover.spec.ts`: `keeps the bottom-right grid menu inside the viewport` (Visual regression layout issue: Floating UI `flip` middleware fails to respect viewport boundary in constrained height scenarios. Verified 2025-02-23, fix attempt failed.)
+- `tests/e2e/popover.spec.ts`: `keeps the bottom-right grid menu inside the viewport`
+  - **Issue:** Visual regression layout issue: Floating UI `flip` middleware fails to respect viewport boundary in constrained height scenarios.
+  - **Reference:** `issues/popover-flip-bug.md`
+  - **Status:** Verification attempted 2026-02-08 but failed due to missing `@playwright/test`. (Verified 2025-02-23, fix attempt failed.)
 
 ### 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`.

+# ModerationService Overview
+
+The `ModerationService` is the central authority for Trust & Safety within the application. It implements a "Web of Trust" model to filter content, aggregating reports (NIP-56) and mute lists (NIP-51) to determine the visibility and safety level of content.
+
+## Core Concepts
+
+### 1. Web of Trust
+Instead of a centralized moderation authority, the service builds a local "trust graph" based on the user's social connections:
+- **Viewer**: The currently logged-in user.
+- **Trusted Contacts**: Users followed by the Viewer (Kind 3 contact list).
+- **Trusted Seeds**: An optional set of admin-defined pubkeys that provide a baseline of trust (e.g., project maintainers).
+- **Admin Whitelist/Blacklist**: Hardcoded lists in `accessControl` that override dynamic trust.
+
+### 2. Trust Aggregation
+When a piece of content (Event) is reported (Kind 1984), the service aggregates these reports but *only counts reports from trusted users*.
+- **Untrusted Reports**: Ignored by default.
+- **Trusted Reports**: Count towards the "trust score" for a specific category (e.g., "nudity", "spam").
+
+### 3. Thresholds
+The service defines thresholds for automatic actions based on the trusted report count:
+- **`AUTOPLAY_TRUST_THRESHOLD` (1)**: If ≥1 trusted user reports content as NSFW/Spam, autoplay is disabled.
+- **`BLUR_TRUST_THRESHOLD` (1)**: If ≥1 trusted user reports content, it is blurred by default.
+- **`TRUSTED_MUTE_WINDOW_DAYS` (60)**: Mute list entries are considered valid for 60 days to prevent stale mutes from persisting forever.
+
+## Architecture
+
+```mermaid
+graph TD
+    User[User / Viewer] -->|Follows| Contacts[Trusted Contacts]
+    Admins[Admin / Seed List] -->|Augments| Contacts

+    Reports[Report Events (Kind 1984)] -->|Ingested| Service[Moderation Service]

+
+    Service -->|Aggregates| Summary[Trusted Report Summary]
+    Summary -->|Checks Thresholds| UI[UI Components]
+
+    UI -->|Blur / Hide| Content
+```
+
+## Data Flow
+
+1.  **Initialization**:
+    - The service initializes with empty sets.
+    - When `setViewerPubkey(pubkey)` is called, it fetches the user's Kind 3 Contact List.
+    - It merges these contacts with any configured `trustedSeedContacts`.
+
+2.  **Report Ingestion**:
+    - The service subscribes to Kind 1984 events referencing active content.
+    - When a report arrives, `ingestReportEvent` checks if the reporter is in the `trustedContacts` set.
+    - If trusted, the report is indexed by `targetEventId` -> `reportType`.
+
+3.  **Summary Recomputation**:
+    - `recomputeSummaryForEvent` calculates the total number of *trusted* reports per category.
+    - It emits a `summary` event, which UI components listen to (e.g., `VideoCard`).
+    - It logs "threshold transitions" (e.g., "autoplay-block-enabled") to the user logger.
+
+4.  **Muting**:
+    - **Viewer Mutes**: The user's own Kind 10000 mute list. Directly hides content.
+    - **Trusted Mutes**: Aggregates mute lists from trusted contacts. If enough trusted users mute an author, that author may be flagged (feature partially implemented via `trustedMutedAuthors`).
+
+## Key Methods
+
+-   `setViewerPubkey(pubkey)`: Switches the active user context, reloading trust lists.
+-   `submitReport({ eventId, type, ... })`: Publishes a NIP-56 report to relays.
+-   `getTrustedReportSummary(eventId)`: Returns the current trust status for an event.
+-   `getAccessControlStatus(pubkey)`: Checks against the hardcoded Admin Whitelist/Blacklist.
+
+## Internal Utilities
+
+The file includes internal implementations of `bech32` encoding/decoding. This is done to:
+1.  Reduce external dependencies for critical path logic.
+2.  Ensure consistent handling of `npub` / `hex` conversions without relying on the global `NostrTools` object potentially being unavailable or different versions.

+# Popover Flip Bug in Constrained Viewports
+
+## Problem
+
+The popover (using Floating UI `flip` middleware) fails to respect viewport boundaries in constrained height scenarios, causing it to overlap or be cut off instead of flipping to the top.
+
+## Affected Components
+
+- `js/ui/overlay/popoverEngine.js`
+- Popovers triggered from `data-test-trigger="grid-bottom-right"` (e.g., in `tests/e2e/popover.spec.ts`).
+
+## Reproduction Steps
+
+1. Open a popover near the bottom of a constrained viewport.
+2. Ensure there is enough space above the popover to flip.
+3. Observe that the popover stays at the bottom and is clipped.
+
+## Test Case
+
+- `tests/e2e/popover.spec.ts`: "keeps the bottom-right grid menu inside the viewport" (skipped).
+
+## History
+
+- **2025-02-23**: Verification failed. Fix attempt failed.
+- **2026-02-08**: Verification attempted but failed due to missing environment dependencies (`@playwright/test`).
+
+## Possible Causes
+
+- Misconfiguration of `flip` middleware (padding, boundary).

+# 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.
+
+## Tags
