Public OSS contributions

anufrievroman/waypaper

Scaling algorithms exposed across swww and awww backends with HiDPI and pixel-art artifact resolution; unified the filter surface for downstream wallpaper daemons.

aome510/spotify-player

Disambiguated is_active Connect device presence from active playback is_playing inside new_session; prevents librespot audio engine starvation when standby smart speakers report presence without an audio stream.

aome510/spotify-player

Serialized concurrent search requests to eliminate HTTP 429 QUOTA_EXCEEDED bursts during rapid TUI navigation.

Freedesktop/PipeWire

Five-second spa timer on pw_protocol_native_connect_local_socket; prevents indefinite CLI hangs in wpctl and pactl when the daemon is alive but unresponsive. Published upstream on Freedesktop.

github-mirror/Niri

Pull-based typed diagnostics over Niri IPC with semantic asset labeling and per-output mutex; anchored five upstream PRs against the window manager.

LOUST-PRO/lzt-algorithms-rs

Three crates (lzt-cart, lzt-entropy, lzt-embedded-trees) covering decision-tree learning, entropy primitives, and embedded tree containers; 32 unit tests and cross-compile targets for embedded Rust.

LOUST-PRO/lzt-virtuoso-tools

JSONL-to-NT Go ingestion tool plus five companion bash scripts that load a corpus into Virtuoso; 17 of 17 smoke tests passing and the sanitize gate is wired into the publish flow.

LOUST-PRO/unattended-upgrade-stuck-kill

First LZT project promoted to an upstream-agnostic refactor template at v1.0.0; demonstrates the brand-cleanup playbook and LICENSE-FORK separation between internal jargon and public methodology.

louzt/louzt

Math foundation for O(1) local context compaction in agentic AI control planes: FNV-1a 128-dim projection + L2 normalization + cosine similarity, with Chernoff-Hoeffding concentration bounds. Anchors the deterministic-sovereign-rag companion repository and the lzt-knowledge-bridge-mcp meta-tool.

louzt/louzt

Evidence and ApacheBench branch-split validation harness for the runtime CRLF injection vector in NGINX via $uri propagation through proxy_pass, proxy_set_header, add_header, and add_trailer. Hardens ngx_http_proxy_module.c + ngx_http_headers_filter_module.c against header smuggling. 4.6k-4.9k req/s under sanitization.

louzt/louzt

Deterministic agent_id provenance tagging + Redis branch ownership registry + H16 hook guard for multi-agent Claude Code sessions. EN+ES, Apache-2.0. Five files: NOTICE + EN/ES markdown + agent-id-derive.sh + agent-id-derive.es.sh. Pairs with the lzt-harness plugin.

louzt/louzt

Four-file RFC patch series for NVIDIA 550.x/580.x DKMS on Linux Kernel 7.0+: nvidia-7.0-drm.patch + nvidia-7.0-vma.patch + nvidia-7.0-vmflags.patch + nvidia-kernel-7-fix.md (Wayland USB-C D3cold fix + strlcpy→strscpy note). Eradicates kernel panics and GPU suspend/resume lockups on Optimus hybrid laptops.

louzt/louzt

Detect and reap stalled TCP long-poll connections on self-hosted CI runners: 3-layer watchdog, capability-aware ss parsing, shared sentinel file, atomic deploy with rollback, and 5 guardrail layers. Production-tested reference architecture for GitHub Actions runners; pairs with LOUST-PRO/lzt-broker-stall-reaper.

louzt/louzt

Reproducible architecture for stall detection plus production hardening on VPS self-hosted GitHub Actions runners. Phase B hardening cascade with 7 documented rollbacks and 10 cross-cutting learnings. Pairs with TCP stall detection gist and LOUST-PRO/lzt-broker-stall-reaper.

louzt/louzt

Three patterns that actually work for laptop↔VPS state replication: (A) snapshot+apply for SQLite/JSON, (B) scp+manifest+3-way merge for config trees, (C) sshfs FUSE write-through for live edit. Decision matrix plus hard rules plus verification checklist; validated in production against lzt-hub-sync B1.9 and socialspheremx-db-sync.

louzt/louzt

v2 (2026-08-12) hex-encoded %i canonical for paths with internal dashes; dual-decode preserves v1 instances. Drop-ins left as caps-only; 5-variant reference table describes the mutability options. Validator reports detected variant per template (WARN-not-FAIL).

louzt/louzt

Five-tier fallback transport proxy racing QUIC / Hysteria2 / TLS / SSH in under 200 ms with CA-pinned topology. Pairs with the louzt/quic-tunnel repository and the Spanish-language bypass-tls-direct variant at e318d7e0ae1fd676d124311c80585f74.

louzt/louzt

Generic systemd restart-loop tripwire (bash, ES+EN); works with any systemd unit via RESTART_TRIPWIRE_SERVICE env var. Default thresholds: 3 restarts in 300s. Includes systemd .service plus .timer; refactored from lzt-hysteria-backoff.

louzt/louzt

Garbage collector for Quickshell runtime dirs. Cleans /tmp/quickshell-* plus ~/.cache/quickshell/{*.tmp,*.log,cache-*} plus /run/user/<uid>/quickshell (only if process dead). Idempotent. systemd .service plus .timer included. ES+EN comments; refactored from lzt-quickshell-runtime-gc.

louzt/louzt

Atomic hourly backup of ~/.local/bin/ (symlinks, scripts, binaries) to a timestamped state dir. Restore is conservative — only fills missing entries, never overwrites installer-installed binaries. Retention 7 days (configurable). systemd .service plus .timer included; refactored from lzt-bin-snapshot plus lzt-bin-restore.

ramsayleung/rspotify

Identified API schema drift in GET /v1/me/shows where omitted available_markets broke Serde deserialization; proposed a non-breaking serde default fallback preserving the Vec<String> public API stability.

stalwartlabs/stalwart

Forward-flow reference deployment built on Stalwart 1.0.0 JMAP; demonstrates cross-account admin workflow and sieve-driven forwarding without modifying the upstream server.

ValveSoftware/Fossilize

PR_SET_PDEATHSIG plus getppid race-check in fossilize_replay_linux and external_replayer; terminates orphan Vulkan shader replayers when Steam or Proton crashes, eliminating 100 percent CPU runaway worker leaks and battery drain across millions of Steam Deck, SteamOS, and Linux gaming devices.

ValveSoftware/Fossilize

NARRATIVE: Catalyzed by Lou (Valve-authored PR). The bucket-json-system metadata plus FNV-1a de-hashing using the vendor matrix was authored by the Valve team after Lou's PR #305 demonstrated the orphan-worker class of bugs; Lou is credited in the discussion but is not a commit author on this PR.

ValveSoftware/Fossilize

roundtrip-checker companion suite that validates shader replay capture and replay round-trips end to end; pairs with the static_assert compile-time safeguard in PR #311.

ValveSoftware/Fossilize

fossilize-list RESOURCE_BUCKET_INFO enum alignment plus a static_assert compile-time safeguard preventing out-of-bounds array reads in the bucket tag reader; merged upstream and unblocked the +7913 LOC fossilize-feature-sifter Mesa CI silicon audit suite.
