[Unreleased]

Sidebar logger recursion: Fixed wpawLog.error/log/warn calling themselves recursively (now call console.* directly)
Sidebar syntax: Restored valid JavaScript syntax after debug logger conversion damaged string literals
Cost tracker backward compatibility: Added record_usage() method to match WP AI Client wrapper contract
Cost attribution: Added record_usage_full() method for accurate model/provider attribution in cost records
Cost table self-heal: Added SHOW TABLES LIKE guard before DESCRIBE to handle missing table scenario
Conversation table versioning: Fixed independent version tracking for conversations table vs. main plugin version
Clear context behavior: Context service now clears all active sessions for a post when sessionId is not provided
Deactivation cleanup: Now clears wpaw_cleanup_old_sessions scheduled hook
Legacy chat history migration: migrate_legacy_chat_history() now deletes legacy meta and writes migration marker; get_context() performs migrate-on-read for posts with unmigrated legacy data
Legacy chat history deprecated: update_post_chat_history() no longer writes to post meta; endpoint returns deprecation notice

Post-scoped authorization (complete sweep): Added edit_post capability checks to ALL post-scoped REST endpoints:
- handle_clear_context, handle_revise_plan, handle_block_refine, handle_refine_from_chat
- handle_seo_audit, handle_suggest_keywords, handle_suggest_improvements
- Plus all previously fixed endpoints (chat, generate-plan, execute-article, reformat-blocks, regenerate-block, meta, image ops)
Frontend debug logging: Added centralized debug logging utility (wpawLog) that respects the wpAgenticWriter.debug flag
Schema sync: Cost tracking table CREATE statement now includes all columns (provider, session_id, status) with runtime migration fallback
Uninstall cleanup: Consolidated uninstall hooks and removed redundant code paths

record_usage() deprecated: Marked record_usage() as deprecated in docblock; use record_usage_full() for accurate provider attribution

Legacy chat history: Post meta _wpaw_chat_history is deleted after successful migration (replaced by _wpaw_chat_history_migrated marker)

Provider transparency: Provider selection now returns structured result with selected_provider, actual_provider, and fallback_used flags
Cost tracking enhancements: Extended cost tracking to capture provider name, session ID, and request status
Authorization hardening: Added edit_post capability checks to REST API endpoints for writing state and conversations

OpenRouter cache conflict: Split single transient into separate keys for model IDs and model objects
Provider contract mismatch: All provider calls now properly unwrap the WPAW_Provider_Selection_Result object
Streaming chat variables: Added proper initialization for accumulated_content, chunks_emitted, total_cost before closure use
Post meta bloat: Stopped writing _wpaw_chat_history to post meta (conversations table is now the source of truth)
