claude-botandClaude Opus 5 00f2239a93 test(e2e): assert the alias where it is observable, not by posting to it
The check posted a completion under the descriptive model name and asserted a
reply came back. That proves nothing: a single-model llama-server ignores the
request's `model` field entirely. Confirmed against the live endpoint — it
answers to "voellig-erfundenes-modell-xyz" and reports "model":"chat" — so the
check passed whether or not the alias existed.

/v1/models is the only place the alias is observable, and it is what a client
reads to populate a picker, so both names are asserted there instead.

claude-botandClaude Opus 5 4fc4343329 test(e2e): regression suite for the local AI endpoint
Every defect this stack shipped so far passed manifest validation and a 200
status code, and was only visible by using the endpoint. So the checks assert
behaviour, not liveness:

  - the embedding model is absent from the chat endpoint, and /v1/embeddings is
    not reachable through the ingress. It used to share the port, appeared in
    the chat picker, and answered chat completions with fluent nonsense rather
    than an error, because --embeddings does not refuse them.
  - a completion returns non-empty content and finish_reason "stop". With
    thinking on by default the model spent its whole budget on
    reasoning_content and returned an empty answer inside a 200 response, which
    a status-code assertion passes.
  - the answer is coherent (knows Paris). llama-bench measures throughput and
    would report excellent numbers for a backend emitting garbage.
  - both the descriptive id and the `chat` handle route to the model.
  - llama-embed serves a vector, reached from the monitoring namespace that
    ai-ns.yaml admits, since that Service has no ingress by design.
  - the Deployment still holds its gpu.intel.com/i915 allocation. Without it the
    pod runs happily on CPU and only a throughput measurement would notice.

Lives in e2e-test.sh rather than scripts/ci/: these need a running model, and
the scripts/ci suites are contractually offline. It therefore runs on the daily
and weekly crons via e2e.yml and on the manual e2e-test target.

Two helpers added alongside the existing ones: llm_chat POSTs through the
ingress, helper_post POSTs from inside e2e-helper for Services with no ingress.

# llama-server WebUI gate
#
# llama-server has no authentication of its own — it serves its chat UI
# and a full OpenAI-compatible API to anyone who can reach the port. That
# is why it was LAN-only until now. This gate is what makes a public
# hostname defensible: the outpost terminates every request, enforces the
# session, and only then forwards to llama-server.
#
# Same reasoning as vscode-gate, and the same passkey step-up: what sits
# behind the gate is entirely unprotected, so the gate is the whole of the
# access control rather than a second factor on top of an app login.
#
# In-cluster consumers (Home Assistant, Paperless, CI) are unaffected:
# they address llama-server.ai.svc.cluster.local directly and never pass
# through Traefik or this outpost.
#
# No group and no policy binding: any user who can authenticate gets in,
# as with Immich, Audiobookshelf, Home Assistant and Music Assistant. The
# gates that pin membership to a named user in git — vscode, esphome,
# zigbee2mqtt, shelly-manager, prometheus — are admin interfaces, where
# the allowlist is the point. A chat UI is not one of those, and deciding
# its membership here would put an access-control choice in a manifest
# instead of leaving it where the user directory belongs.

# in opposite directions, with all 12 restores at phase=Completed and the
# other 46 checks green. Parity compares a backup taken up to ~24 h ago
# against the live volume *now*, so a single config write on a tiny volume
# between those two moments is expected, not a defect in the backup.
#
# The floor only governs volumes below ~10*ABS_PARITY_SLACK files; above

# carry data keeps failing loudly. Two files of slack rather than one
# because a single logical write on a config volume routinely moves more
# than one file (an app writing a settings file plus a transient sidecar),
# and a floor that buys exactly one month is not worth the change.
#
# What the floor must NOT swallow, and does not: a non-empty source that
# restored to an *empty* volume fails unconditionally below, before any
# tolerance is applied. The old relative-only check caught that case as a
# side effect (delta = 1.0 > 0.10); it is now explicit so the floor cannot

# Capability evaluation for a chat model: which of this homelab's real workloads
# can it actually take on?
#
# This is a comparison tool, not a CI gate. Point it at any OpenAI-compatible
# endpoint and model and it prints the same scored tasks, so two models can be
# judged side by side on the work we would give them rather than on a public
# leaderboard.
#
# The tasks are drawn from real workloads:
# A PR review triage — the actual rubric from ci/agents/pr-review/, run over
# real merged PR diffs whose correct classification is known. Includes a
# prompt-injection case, since the triage reads attacker-controlled input
# and the pipeline trusts it to hold.
# B Strict JSON output, five identical runs — Home Assistant intents need
# parseable output every time, not usually.
# C German document classification — the Paperless workload.
# D German summarization under a hard length constraint.
#
# Usage:
# scripts/ai-eval.sh # the cluster's local model
# scripts/ai-eval.sh -m qwen3.6-35b-a3b
# scripts/ai-eval.sh -e https://other/v1/chat/completions -m some-model -k KEY
#
# Env equivalents: AI_EVAL_ENDPOINT, AI_EVAL_MODEL, AI_EVAL_KEY.
#
# To compare two models on OUR llama-server, -m is not enough: a single-model
# server ignores the request's `model` field entirely and answers to any name.
# Change --hf-repo in kubernetes/apps/llama-server/deployment.yaml, let it roll
# out, then re-run. -m matters for routing servers and for hosted APIs.
#
# Exit code is the number of failed tasks, so a run can be compared mechanically.
