-### Fixed
-- **YouTube Mosaic Exemption**: Implemented high-precision detection for the YouTube mosaic in `docs/index.md`, ensuring that only the primary high-density block is exempt from health checks, while other YouTube links (before the mosaic and in collapsible notes) are properly checked.
-- **README Metrics Restoration**: Fixed the git checkout depth (`fetch-depth: 0`) in the V2 publisher workflow to restore accurate historical metric generation for the README.
-- **Iframe Health Checks**: Added support for detecting and checking YouTube links within `<iframe>` tags in the index file.

-- **YouTube Mosaic Update**: Added YouTuber @mouredev (Brais Moure) to the YouTube mosaic in both V1 and V2 index portals.
+### Changed
+- **Centralized YouTube Enrichment**: Standardized YouTube metadata extraction across all curation pipelines (V1 and V2). All workflows now fetch real titles and descriptions from YouTube to ensure high-fidelity AI summaries.
+- **Workflow Modularization**: Reverted the consolidation of the Video Hub into the Publisher pipeline, maintaining it as a standalone workflow (`agentic_v2_videos.yml`) for better operational flexibility.
+- **Improved Video Hub Design**: Redesigned the V2 Elite Video Hub with high-fidelity categorization, technology tags, and individual collapsible blocks for better user experience and flow.

-
-### Added
-- **Comparative Knowledge Metrics**: Enhanced the V2 Portal index with V1 vs V2 inventory comparison, showing the total base resources analyzed and the elite selection density ratio.
-- **Agentic Efficiency Tracking**: Integrated real-time calculation of the curation delta between the master archive and the high-density portal.
-
-
-## [2.0.0-rc.7] - 2026-05-22
-
-### Fixed
-- **GitHub Metadata Metrics**: Corrected the coverage calculation logic in `v2_optimizer.py` to properly identify GitHub repositories by ensuring URLs are correctly injected into the resource objects during the audit phase.
-- **Knowledge Graph Integrity**: Resolved the 0% reporting bug in the V2 Portal index, ensuring accurate tracking of resource maturity.
-
-### Changed
-- **Pipeline Orchestration**: Successfully validated the new decoupled workflow system by performing a manual execution of the Metadata and Publisher engines.
-
-
-## [2.0.0-rc.6] - 2026-05-22
-
-### Added
-- **High-Density Inline Summaries**: Replaced collapsible blocks with always-visible summaries appended directly to the resource line using an em-dash (—) separator for immediate readability.
-
-### Fixed
-- **V2 Rendering Engine**: Resolved a critical `TypeError` caused by incorrect indentation in the link rendering logic.
-- **Workflow Reliability**: Standardized all GitHub Actions to use Python module execution mode (`python -m src.module`), eliminating `ModuleNotFoundError` issues.
-
-## [2.0.0-rc.5] - 2026-05-22
-
-### Added
-- **Decoupled V2 Architecture**: Refactored the monolithic V2 builder into four specialized micro-workflows (**Health Monitor**, **Metadata Engine**, **AI Curator**, and **Publisher**) to optimize compute quotas and Gemini token consumption.
-- **Minimalist Inline UI**: Implemented native HTML5 `<details>` summaries with `inline-block` behavior in the V2 Portal, significantly increasing vertical information density.
-- **Knowledge Coverage Metrics**: Integrated real-time AI Enrichment and GitHub Metadata coverage tracking into PR reports and the V2 index.
-- **Automated Scheduling**: Configured monthly automated runs for Health (1st) and Metadata (15th) agents.
-
-### Fixed
-- **V2 Rendering Logic**: Fixed a bug where links without a defined hierarchy or at top-level categories were omitted; introduced the **Standard Reference** fallback section.
-- **Markdown Linting**: Resolved TOC anchor broken links (MD051) in `README.md`.
-
-## [2.0.0-rc.4] - 2026-05-22
-
-### Added
-- **Mosaic Expansion**: Added Olena Kutsenko's YouTube channel to the index mosaic on both V1 and V2, including custom profile picture extraction and asset synchronization.
-
-## [2.0.0-rc.3] - 2026-05-21
-
-### Added
-- **Flash-First Architecture**: Strategic transition to Gemini Flash/Lite models for high-density analysis, achieving >90% cost reduction and radical throughput gains.
-- **Multi-Phase Incremental Persistence**: Dual-layer auto-save mechanism (Metadata & AI phases) ensuring zero data loss during long-running CI/CD workflows.
-- **Industrial Telemetry Layer**: Deep AI observability with token counting, payload estimation, and transparent error diagnostics.
-- **GitHub Actions Cache Integration**: High-resilience persistence layer to reuse enriched metadata across interrupted or queued runs.
-- **Emergency PR Workflow**: Lightweight "Safety Off-ramp" to publish current cached state without AI overhead.
-
-### Changed
-- **Optimized Batching Strategy**: Balanced batch sizes (50 items) and safety delays (2s) to maximize API quota utilization (TPM/RPM).
-- **Hardened Error Handling**: Transitioned from silent failure loops to strict Circuit Breaker (Exit Code 42) logic.
-- **Unified Global Logging**: Enforced `PYTHONUNBUFFERED` logging across the entire workflow ecosystem for real-time transparency.
-- **V2 UI Refinement**: Optimized header contrast for Light/Dark modes and fixed semantic cross-link duplication.
-
-### Fixed
-- **API Timeout Bottleneck**: Increased HTTP request timeouts to 180s to accommodate high-density token generation.
-- **Markdown Linter Compliance**: Resolved MD024, MD025, MD031, and MD039 violations through "Nuclear" whitespace sanitization and header depth management.
