The user lookup function previously iterated over the entire user list sequentially,
causing O(n) latency for each request. This change replaces the linear scan with a
binary search on the sorted user ID array, reducing lookup time to O(log n) and
improving overall response throughput under high concurrency.
The user lookup endpoint previously used a linear scan over the user list,
which degraded performance under high concurrency. This change replaces
the search algorithm with a binary search on the sorted user ID array,
reducing average lookup time from O(n) to O(log n). The user list is
maintained in sorted order via insertion sort on new user registration.
The README now includes a high-level description of the project's purpose, a prerequisites section listing required tools, and step-by-step installation and configuration commands for new contributors.

Adds a new BotManager class that maintains a mutable list of active bots, allowing bots to be added or removed at runtime without restarting the application. Includes thread-safe operations for concurrent access and a new API endpoint to query the current bot roster.
The algorithm analyzes user interaction patterns to identify anomalous behavior, flagging accounts with irregular login times, rapid-fire actions, or unusual data access sequences. It integrates with the existing monitoring pipeline to generate alerts for security review.
The polling interval for the metrics collection service has been adjusted from 30 seconds to 60 seconds to reduce system load and network traffic while maintaining adequate monitoring granularity.
The commit introduces a new image file intended for use as a default avatar when a user has not uploaded a custom profile picture. This ensures visual consistency across the user interface by providing a generic fallback graphic.
The previous thread pool implementation caused GIL contention under heavy CPU workloads. This change swaps concurrent.futures.ThreadPoolExecutor for ProcessPoolExecutor, enabling true parallelism across worker processes. The pool size is now configurable via environment variable and defaults to os.cpu_count(). Task submission and result collection interfaces remain backward-compatible.
The profiles table previously lacked an index on the user_id column, causing slow query performance when filtering by user. This change adds a B-tree index on user_id to optimize read operations in the user profile retrieval endpoint.
Implement a new content validation module that scans comment text for potentially harmful or inappropriate patterns before submission. The checker uses regex-based pattern matching to flag common spam, abuse, and prohibited content, returning a boolean result for downstream moderation handling.
Implement a new logging utility with configurable verbosity levels and integrate a rant_history data structure to persist user interaction records across sessions. The logging module includes timestamped entries with severity tags, while rant_history stores chronological entries with metadata for future analysis and replay features.
