**Generated**: 2026-03-19 +> **Scope**: Deep inspection of the full repository tree, build system, tests, code quality, CI/CD, documentation, and open gaps. + +--- + +## Executive Summary + +RootStream is a Linux-first, self-hosted, peer-to-peer game streaming toolchain. The +repository is in a mature state: the core Linux host↔client path builds cleanly, unit +tests pass at 100%, and an extensive microtask-driven development programme (phases 0–108) +has been completed with 570 documented microtasks. + +This report identifies three remaining areas required to reach **world-class and legendary** +quality: + +1. **Code formatting** — 458 source files deviate from the `.clang-format` style config. +2. **Source TODOs** — 18 TODO/FIXME annotations remain in production code paths. +3. **Progress registry accuracy** — the microtask header counter is stale. + +New execution phases (PHASE-109 through PHASE-112) are defined in +[`docs/microtasks.md`](microtasks.md) to close these gaps. + +--- + +## Build Health + +| Check | Result | Notes | +|-------|--------|-------| +| `make HEADLESS=1` | ✅ Clean | All required deps present | +| `make test-build` | ✅ Clean | Crypto and encoding test binaries built | +| `./tests/unit/test_crypto` | ✅ 10/10 | All crypto tests pass | +| `./tests/unit/test_encoding` | ✅ 18/18 | All encoding tests pass | +| `make DEBUG=1 HEADLESS=1` | ✅ Clean | Debug build succeeds | +| clang-format check | ❌ 458 violations | See PHASE-109 | + +**Dependencies satisfied in test environment**: +libsodium, libopus, libdrm, libsdl2, libva, libqrencode, libpng, libx11-dev + +--- + +## Test Coverage + +| Suite | Count | Pass | Fail | +|-------|-------|------|------| +| Crypto unit tests | 10 | 10 | 0 | +| Encoding unit tests | 18 | 18 | 0 | +| Integration tests | via CI | CI-gated | — | +| Sanitizer (ASan/UBSan) | via CI | CI-gated | — | +| Valgrind memory check | via CI | CI-gated | — | + +The Makefile `test-build` target builds two test binaries.
