July 2026 monthly summary focused on delivering governance, testability, and codec improvements across the OpenVisualCloud/Media-Transport-Library repository. Highlights include governance enhancements, cross-module codec support, expanded admin tooling, and robust unit-test readiness that collectively boost reliability, traceability, and developer velocity. Key achievements: - RFC 8331 codec helpers integrated across TX ancillary build, ST40 TX encode path, RX parsing, GStreamer plugin, and test suites, with corresponding tests to ensure parity and correctness. This reduces duplication and fixes parity/CRC handling across multiple components. - Planner guardrails and Gate exemptions implemented with mandatory alignment: improved upfront acceptance criteria capture, a rise in correctness of gate decisions (Gate 2/6 exemptions), and clearer provenance via renamed Guardrails section. - System Admin and Validation Setup access expansion: broadened tool access for System Admin and Validation Setup agents, enabling better host-setup tracking and streamlined investigation readiness. - mtl-commit skill established as the single source of truth for commit messages: standardized commit messaging rules surfaced to agents, improving consistency and audits. - Unit test harness and build system improvements: added unit build option via build.sh, introduced guards such as MT_HANDLE_GUARD, and implemented protections for udw_offset sizing to improve unit-test reliability and build robustness.

Monthly summary for 2026-04 focusing on developer performance and business value. Key features delivered: - RX ST40P ancillary pipeline support implemented in RxTxApp: new session handling (rx_st40p) with per-session results (frames, fps, seq_discont, marker_missing, seq_lost), JSON parser support for rx_sessions[].st40p, wiring across config/build, and end-to-end validation. All 7 tests pass on E810 hardware, demonstrating production readiness. - Wire-stats reconciliation added to RxTxApp results for ST20p/ST30p/ST40p: when fps mismatches or wire-side counters diverge, a one-line reconciliation is printed to explain the discrepancy, improving operator visibility. - Per-port RX statistics & frame-level counters: introduced per-port RX stats (reorder, duplicate, etc.) across video/audio/ancillary/fastmetadata paths; exposed in st_api.h and summarized in updated stats guide; supports deeper per-port diagnostics and enterprise reporting. - Frame-level counters and stat_frames_corrupted: added per-frame metrics (frames_received, frames_dropped, etc.) and stat_frames_corrupted for ST20p RX to improve frame-accuracy reporting and troubleshooting. - Extended ST2022-7 RX coverage: expanded unit-test coverage for ST20/ST30/ST40 to ensure cross-media parity under dual-path redundancy; added comprehensive RX tests for ST20/ST30/ST40/ST40p. - Public session-handle lifecycle hardening: serialized get/put/update/free APIs; reproducer added for concurrent get/reset_session_stats vs free to prevent UAF/ races; lifecycle guard pattern implemented in public APIs. - Documentation and tests: added session statistics guide; reorganized st_user_stats grouping by software layer; introduced fuzzing/test harness improvements to support maintainability. Major bugs fixed: - Logging noise reduction: downgrade critical log level to notice for informational messages (e.g., link dumps and test results) to align with user expectations. - Stats correctness: fix type mismatches and remove dead/redundant counters; ensure uint64_t formatting and delta calculations are correct. - Thread-safety: make get/reset_session_stats thread-safe and consistent across calls; guard against races with data-path tasks. - OOO and sequence handling: fix per-port OOO wraparound, ST20 video OOO underflow, and stall/incorrect gap accounting when backward or cross-port reordering occurs. - Redundancy path fixes: differentiate redundant filtering from real errors in RX audio/anc; avoid inflating error counters on redundant packets; adjust threshold bypass semantics. - Public API correctness: serialize public session-handle APIs against *_free to prevent races and use lifecycle gates to guarantee safe teardown. Overall impact and accomplishments: - Significantly improved reliability and observability for high-availability media workflows through robust RX/TX statistics, improved inference of wire vs. application-level losses, and stronger protection against lifecycle races. - Increased confidence in dual-path redundancy behavior via extended ST2022-7 test coverage and wire-stats reconciliation, enabling faster operator diagnosis and root-cause analysis. - Accelerated delivery with production-quality tests, clearer docs, and safer, scalable session-handle APIs. Technologies/skills demonstrated: - C11 atomics and thread-safety patterns for get/reset/session lifecycle protection. - Per-port and per-session statistics architecture, including future-proofing for ST20/ST30/ST40/ST40p paths. - ST2022-7 dual-path redundancy concepts and cross-media test design. - Meson build integration and unit-test infrastructure, with fuzz/test harness improvements. - Comprehensive documentation and developer-focused guidance for statistics and debugging.
