User report after the llamacpp app install: 'installed llama.cpp unknown',
valid flags rejected (randomly per run), 'Model not found' for the HF
downloader's own layout, and a systemd user-bus failure over SSH. Detective
(real b10822 binary, FACT) found four independent causes:
- version: llama-server --version prints to STDERR; detect_llama_version's
2>/dev/null swallowed it -> always 'unknown'. Now captures 2>&1 + accepts
semver/build tokens (incl. build 1.2.3 edge)
- validation: printf|grep -q under pipefail -> SIGPIPE rc=141 race randomly
rejected flags present in the 59 KB --help. Now pipe-less grep (no race);
20x determinism regression test
- model resolution: resolve_model accepted files only, but the HF downloader
creates <models>/<repo>/file.gguf dirs. Now expands a dir with exactly one
*.gguf (never silently picks; multi-gguf lists + errs)
- port: llama.cpp default 8080 vs tool/adapter 8088; validation reliability
means --port is now always pinned in the unit
- user bus: headless/SSH sessions lack XDG_RUNTIME_DIR -> ensure_user_bus in
lib/common.sh pre-flights all three systemctl --user tools with remediation
text; pos ai server --no-unit direct-run escape hatch (pidfile) for boxes
with no bus
- find_llamacpp narrowed to llama-server/llama-server-cuda (bare 'server'
fallback hazard); installer post-install sanity (version+help execute,
symlink targets resolve)
Architect decisions DQ1-DQ6 recorded. Tester: 4 new regression files
(version-from-stderr, 25x flag-validation determinism, model dir expansion,
bus pre-flight + E2E) + 3 fixture updates; suite 16 files / 269 checks.
Verified: make gen idempotent; make check OK; make lint 0 FAIL, 0 WARN;
make test 269/269 (~49s); bash -n clean; git diff --check clean.
