rob thijssen	18ae3c30ee	post-validation cleanup: cuDNN runtime + repetition penalty ... Two followups from the live single-GPU validation pass. 1. deploy.sh now ensures libcudnn.so.9 is available on each neuron host before installing/upgrading the package. Probes ldconfig first so hosts with a manual (tar/runfile) cuDNN install are untouched, then adds NVIDIA's RHEL9 CUDA repo (the Fedora 43 CUDA repo doesn't ship cuDNN; only the RHEL9 one does) and installs libcudnn9-cuda-13. benjy hit "cannot open shared object file: libcudnn.so.9" during validation; this prevents that recurring. 2. candle.rs applies a 1.1 repetition penalty over the last 64 generated tokens before sampling, in both the non-streaming chat_completion path and the streaming chat_completion_stream path. Without it small Q4_K_M models degenerate into "Wait, no, no..." loops once they hit a confident-but-wrong path; with it sampling stays coherent. Defaults match mistral.rs and llama.cpp; exposing the value via the OpenAI request (frequency/presence penalty mapping) is Stage 8 territory. Both routes through a new sample_with_penalty() helper so future sampling tweaks land in one place. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-19 14:48:08 +03:00
rob thijssen	1a0400131e	fix(deploy): use dnf upgrade for stale installs, install only when absent ... dnf5's `dnf install <pkg>` is a no-op when the package is already installed at ANY version — it does NOT auto-upgrade to the latest available. The deploy script's install branch was therefore silently leaving hosts on older builds even though needs_update correctly reported an upgrade was available. Add an is_installed() probe and an install_or_upgrade() helper that picks the right verb: `dnf install` when fresh, `dnf upgrade` when stale. Captured combined-stream output is exposed via __DNF_OUTPUT__ for the existing failure-diagnostic path. Verified end-to-end against the live fleet: hanzalova/beast/benjy/ quadbrat all upgraded cleanly from prior prerelease NVRs to 0.1.16-0.1.20260519134302.git1866b99.fc43, validation script returned "Paris" from all three neurons. Followup (not in this commit): all hosts running helexa-neuron-* need libcudnn.so.9 available at runtime. Currently: - quadbrat: libcudnn9-cuda-13 RPM (rhel9 CUDA repo) - beast: /usr/lib64/libcudnn.so.9 (manual install) - benjy: needed rhel9 CUDA repo added + libcudnn9-cuda-13 installed as part of this validation pass. The spec currently excludes cuDNN from auto-detected deps. Should add a Recommends:libcudnn9-cuda-13 (soft) and ensure the rhel9 CUDA repo is configured on each neuron host, similar to how ensure_lair_repo handles the unstable channel.

rob thijssen	8a2334eacb	deploy: dnf-native version check + lair.cafe repo bootstrap ... Replaces the string compare of 'git describe --tags' vs the binary's self-reported --version (which lies about prereleases — every 0.1.16-* RPM reports just "0.1.16") with the dnf-native question of "is the installed package current against what the repo offers". Mechanism: - installed_nvr(): rpm -q --qf '%{version}-%{release}' for the resident package, falling back to "(not installed)". Capturing rpm's output through a variable keeps its "package X is not installed" stdout message out of the result on failure. - needs_update(): probes rpm -q first (treats absent as "needs work"), then asks dnf check-update --refresh -q. Other dnf failures collapse into "needs update" so the subsequent install surfaces a real error rather than this check swallowing one silently. - ensure_lair_repo(): probes for /etc/yum.repos.d/lair-cafe-unstable.repo and adds it with `dnf config-manager addrepo` when missing. The upstream .repo file ships enabled=0 (unstable channel doesn't auto-engage on fetch), so we then run `dnf config-manager setopt lair-cafe-unstable.enabled=1` every run — cheap, idempotent. - Cortex and neuron install branches now guard `systemctl stop` with `[ ! -f /usr/lib/systemd/system/...service ] || sudo systemctl stop` so fresh installs (no unit file yet) don't short-circuit the install step under set -e. - dnf output is captured into a variable and only printed (with a [host] prefix per line) on failure, so success stays quiet and failures show the actual diagnostic instead of being eaten by &> /dev/null.
