Refactor js/docsView.js to replace innerHTML with safe DOM APIs

- Replaced 7/8 `innerHTML` instances with `document.createElementNS`, `replaceChildren`, and `setAttribute`
- Updated `scripts/check-innerhtml.mjs` baseline (8 -> 1)
- Retained 1 `innerHTML` instance for `marked.parse` (trusted content)
- Verified functionality with unit tests (`npm run test:unit`) and frontend verification (`Playwright`)
- Created completion log `docs/agents/task-logs/daily/2026-02-16_21-43-55_innerhtml-migration-agent_completed.md`
- Moved temporary artifacts to `artifacts/innerhtml-migration/2026-02-16/`

-**Date:** 2026-02-16
-**Agent:** bitvid-const-refactor-agent (via Daily Scheduler)
-
-## Goal
-Identify and refactor duplicated numeric constants in `js/` to improve maintainability and clarity.
-
-## Scope
-- Search for common numeric literals (e.g., 1000, 5000, 10000).
-- Select a clear candidate group.
-- Replace with a named constant in `js/constants.js` or `js/nostr/relayConstants.js`.
-
-## Constraints
-- Minimal changes.
-- Must pass `npm run lint` and `npm run test:unit`.

-# Context: Constants Refactoring
-
-**Date**: 2026-02-16
-**Agent**: const-refactor-agent (via daily scheduler)
-**Goal**: Identify and canonicalize duplicated numeric literals.
-
-## Scope
-- Focus on the literal `5000` which appears to be a common timeout value.
-- Refactor usages to `SHORT_TIMEOUT_MS` (5000ms) where semantically appropriate.
-
-## Changes
-- `js/ui/videoModalController.js`: `autoHideMs` for status message.
-- `js/nostr/nip46Client.js`: `NIP46_PING_TIMEOUT_MS`.
-- `js/nostr/nip07Permissions.js`: `NIP07_EXTENSION_WAIT_TIMEOUT_MS`.

-# Context: Documentation of js/services/moderationService.js
-
-## Selection
-- **File**: `js/services/moderationService.js`
-- **Line Count**: ~1350 lines
-- **Reason**: This is a critical Trust & Safety module implementing the "Web of Trust" model. It is large, complex, and central to the user experience (filtering, blurring). It lacks comprehensive high-level documentation and detailed JSDoc for its public API.
-- **Goal**: Analyze the file, add in-code JSDoc, and create a `docs/moderationService-overview.md` to explain the trust graph and report aggregation logic.
-
-## Analysis Plan
-1.  **High-level summary**: Web of Trust implementation using NIP-56 (Reports) and NIP-51 (Mutes), filtered by the user's social graph (Kind 3 contacts).
-2.  **Public Surface**: `ModerationService` class, `submitReport`, `recomputeSummaryForEvent`, `refreshViewerFromClient`, `setViewerPubkey`.
-3.  **Key Flows**:
-    -   **Initialization**: `setViewerPubkey` -> `fetchTrustedContacts` -> `rebuildTrustedContacts`.
-    -   **Reporting**: `submitReport` -> sign -> publish -> ingest.
-    -   **Aggregation**: `subscribeToReports` -> `ingestReportEvent` -> `recomputeSummaryForEvent` (checks trust).
-4.  **Invariants**:
-    -   Reports are only counted if the reporter is in `trustedContacts` (or whitelist).
-    -   Admin actions (blacklist/whitelist) override the trust graph.
-    -   Viewer mutes are synchronized with `userBlocks`.
-
-## Tasks
-- [ ] Add file-header JSDoc explaining the module.
-- [ ] Add JSDoc to `ModerationService` methods (`constructor`, `setViewerPubkey`, `submitReport`, etc.).
-- [ ] Create `docs/moderationService-overview.md` with architecture diagrams (text) and usage examples.
-- [ ] Verify with `npm run lint` and `npm run test:unit`.

-# Decisions Log
-
-**Date:** 2026-02-16
-**Agent:** bitvid-decompose-agent
-**File:** `js/ui/profileModalController.js`
-
-## Decisions
-
-### 1. Extract DM Relay Logic
-**Decision:** Extracted DM relay management logic into `ProfileDmRelayController`.
-**Rationale:** The relay logic (add, remove, publish, refresh) was cluttering the main controller and is distinct from core profile management.
-**Implementation:** Created `js/ui/profileModal/ProfileDmRelayController.js` and delegated calls from `ProfileModalController`.
-
-### 2. Extract Attachment Logic
-**Decision:** Extracted attachment handling logic into `ProfileDmAttachmentController`.
-**Rationale:** Attachment uploading, rendering queue, and file selection are a separate concern from the main profile UI.
-**Implementation:** Created `js/ui/profileModal/ProfileDmAttachmentController.js` and delegated calls from `ProfileModalController`.
-
-### 3. Move Helper Methods
-**Decision:** Moved pure helper methods (`generateAttachmentId`, `resolveLatestDirectMessageForRecipient`, etc.) to `ProfileDirectMessageHelper`.
-**Rationale:** Keeps the main controller focused on orchestration rather than utility logic.
-
-### 4. Move Rendering Logic
-**Decision:** Moved rendering methods (`renderAttachmentQueue`, `setMessagesUnreadIndicator`) to `ProfileDirectMessageRenderer`.
-**Rationale:** Separates DOM manipulation from business logic.
-
-### 5. Move Action Logic
-**Decision:** Moved action handlers (`handleSendDmRequest`, `handleSendProfileMessage`, etc.) to `ProfileDirectMessageActions`.
-**Rationale:** Groups user interaction handlers together.
-
-## Impact
-- `js/ui/profileModalController.js`: Reduced by ~405 lines.
-- Improved separation of concerns for Direct Messages within the Profile Modal.

-## 2026-02-16
-
-- **5000 ms used for UI toast duration:**
-  - Chosen canonical constant: `SHORT_TIMEOUT_MS` (from `js/constants.js`)
-  - Location: `js/ui/videoModalController.js`
-  - Reason: `SHORT_TIMEOUT_MS` is already 5000 and semantically fits "short timeout" for auto-hiding status.
-
-- **5000 as MAX_BLOCKLIST_ENTRIES:**
-  - Chosen canonical constant: `MAX_BLOCKLIST_ENTRIES`
-  - Location: `js/constants.js`
-  - Reason: `MAX_BLOCKLIST_ENTRIES` was defined locally in `js/userBlocks.js`. Extracted to `js/constants.js` to centralize limits.
-
-## 2026-02-16 - deps-security-agent
-- **jsdom**: Upgraded to `28.1.0` (Safe patch/minor upgrade verified by tests).

-## Refactor: `10000` -> `STANDARD_TIMEOUT_MS`
-
-- **Value:** `10000` (ms)
-- **Chosen Constant:** `STANDARD_TIMEOUT_MS`
-- **Location:** `js/constants.js` (Existing)
-- **Reasoning:**
-    - Multiple files defined `timeoutMs = 10000` as a default.
-    - `STANDARD_TIMEOUT_MS` already exists in `js/constants.js` with this exact value and intent.
-    - Centralizing this improves consistency and allows global timeout adjustments.
-
-## Rejected Candidates (for this pass)
-- `js/nostrEventSchemas.js` (Kind 10000): Not a time duration.
-- `js/storage/s3-multipart.js` (maxParts 10000): Not a time duration.

-
-- **5000 ms** used in `js/ui/videoModalController.js` for status message auto-hide.

+2.  Refactored 7 instances to use `document.createElementNS`, `replaceChildren`, and `setAttribute`.
+3.  Retained 1 instance for `marked.parse()` as it renders trusted Markdown content; added documentation.
+4.  Updated `scripts/check-innerhtml.mjs` baseline.
+5.  Verified changes with `npm run lint` and `npm run test:unit`.
+6.  Verified frontend functionality with Playwright and visual inspection.
+
+## Artifacts
