lukaszraczylo cfdb2c5aae feat: function-calling (MCP-style) tests plus ultra-hard tasks 
Adds real OpenAI function-calling support end to end and two test tranches.

Client (internal/llm): Request.Tools advertises tools with tool_choice
auto; Response.ToolCalls carries the model's calls, decoding each
function's JSON-encoded argument string into an object (malformed
arguments preserved raw with Decoded=false). Verified live: the gateway
round-trips tools and the qwen/deepseek tool-call parsers emit the
expected format.

Runner: when a test declares Tools, it serializes the model's tool calls
into a canonical JSON envelope and scores that, not the free text.

Eval (toolcall.go): ToolCalled, NoToolCalled, ToolCallWithArgs (subset
match, number/string coercion), ToolSequence, FirstToolIs, ToolNotCalled,
ToolArgValuesCover - all parse the envelope, no llm dependency.

Tests: 12 function-calling tests (tools/function-calling) covering tool
selection, argument extraction, enum constraints, chained and parallel
calls, no-tool-needed and missing-param abstention, destructive-tool
safety, and name-vs-description traps; 8 ultra-hard single-shot tasks in
existing subcategories. Ground-truth self-consistency tests assert every
documented answer and ideal tool envelope scores 1.0.

lukaszraczylo 708622e2a8 feat(tests): add 16 advanced distractor-rich scenarios 
The 2026-08-30 suite-health review found 223/283 tests saturated. These
16 target the failure modes that still discriminated, one per existing
subcategory across all eight categories:

- multi-constraint reasoning: infeasible-plan detection, conflicting
  delegation policy, adversarial tool descriptions
- forensic root-causing from noisy evidence: RAG stage attribution,
  EXPLAIN ANALYZE with a red herring, interleaved multi-source incident
  logs, README-vs-config conflict resolution
- composed gotchas: a Go 1.22 capture + named-return-defer trace, a
  Python late-binding + shared-mutable-default trace
- constraint math: context-budget packing, capacity-fill projection,
  MVCC anomaly classification, Docker layer-rebuild prediction, dual-key
  rotation overlap, freeze-window scheduling, an open-redirect exploit
  chain

Every answer is a structured JSON value scored by an exact evaluator,
never a prose heuristic (the source of every false positive in the
review). A ground-truth self-consistency test asserts each documented
correct answer scores 1.0 through its real evaluator.

lukaszraczylo 6ad9dfbe42 fix(runner): record wall-clock latency on error rows 
An error row with zero latency reads as an instant rejection when it
can be three exhausted request timeouts. A 651-second thinking-model
generation looked instant in the 2026-08-30 run and misdirected the
diagnosis toward gateway rejection. The error path now records the
wall clock across all attempts.

lukaszraczylo 7616f4bdee fix(llm): retry 429 responses and 2xx bodies carrying an error object 
Six qwen3.8-27b-uncensored requests in the 2026-08-30 run failed
instantly with zero tokens while the replica was warming; the gateway
reported them in-band and the client gave up on the first attempt. Both
shapes now retry within the existing backoff budget.

lukaszraczylo d9b7ca9cc4 feat(config): raise max_tokens_default to 40000 
At 25000 the heaviest thinking-model tests exhausted the whole budget
on reasoning and scored zero with an empty answer (8 truncated cells in
the 2026-08-30 3-model run, e.g. ts-eslint-flat-config on
qwen3.8-flash-next at exactly 25000 completion tokens).

lukaszraczylo 499956f8cc fix(tests): disambiguate two prompts, exempt --force-if-includes 
git-detached-head-recovery: all three benchmarked models answered
["branch"], which the prompt's literal ask (save the commits) makes
correct while the evaluator requires ending attached. The prompt now
demands ending checked out on the new branch and names the bare-branch
gap explicitly.

scen-crashloop-order: the instruction excluded only acting steps, so
including the read-only journalctl step E followed the letter of the
prompt. The instruction now asks for the smallest sufficient set and
excludes redundant diagnostics.

git-force-with-lease-vs-force: exempt --force-if-includes, the
stricter safe variant, from the bare --force pattern.

lukaszraczylo 6b0bea1193 fix(eval): remove four negation-detector false-positive classes 
Replay of the 2026-08-30 3-model artifact showed the same correct
answers zeroed for every model. Four mechanical causes, each with a
regression fixture:

- A dot glued to a following non-space character ("e.g.,",
  "release/2.4") cut the clause window between a match and its cue.
  A dot now ends a clause only before whitespace, and common
  abbreviations (e.g., i.e., etc., vs.) never do.
- Markdown emphasis and code fences inflated cue distance past the
  window cap, and fence-adjacent blank lines created fake paragraph
  gaps. The scanner now strips backticks and double asterisks and
  collapses layout gaps around fences before matching.
- A single cue did not distribute over a comma enumeration ("not ...
  kubectl edit, kubectl patch"). An unnegated match now inherits the
  negation of an earlier negated match in the same clause.
- Consequence descriptions ("deterministic", "silently", "will
  replace", "a bare") were not recognized as cues.

Replayed against the saved artifact: 7 of 8 false positives now score
full credit; the eighth stays partial on purpose (that response does
endorse a temporary live edit).

budget). stdout carries only the table/markdown/json report, so `llmtest
run --format json > results.json` stays pipeable regardless of `--quiet`.
With `--repeat N>1`, each (model, test) cell reports the mean over
attempts; when attempts disagreed, the cell appends the `[min-max]` range
and the discrimination rollup flags the test as unstable.
### Comparing two runs
`compare` diffs two saved artifacts (from `--out`) per (model, test) pair.
It re-aggregates each side with the same truncation policy the report
uses, so a comparison stays honest even when only some attempts were cut
off. A mean drop of >= 0.01 is a regression, an equal-size rise an
improvement; tests present on only one side are listed as
`baseline-only`/`current-only`. The exit code reflects only diff
failures (unreadable artifacts), not regressions:
```sh
go run ./cmd/llmtest run --out baseline.json
# ... change config, upgrade the endpoint, swap model ...
go run ./cmd/llmtest run --out current.json
go run ./cmd/llmtest compare baseline.json current.json
```
### Auditing suite health
`health` reads one or more saved artifacts and rolls them up per
subcategory: what share of (model, test) cells score perfect, how many
tests are saturated (perfect in >= 90% of their cells, so they cannot
separate models), and which tests still carry signal. Cells pool across
artifacts taking each (model, test) pair's WORST artifact, so a lucky
re-run cannot hide a failure; subcategories at 100% perfect across every
model contribute zero ranking information and need harder tests:
```sh
go run ./cmd/llmtest run --out run1.json
go run ./cmd/llmtest health run1.json # one artifact
go run ./cmd/llmtest health run1.json run2.json # pooled audit
```
### Reading the discrimination rollup
`table` and `markdown` output end with a `Discrimination` section. Its
headline counts the tests whose cross-model score spread reaches
`DiscriminationSpread` (0.05) - the tests that actually separate models -
plus the tests whose repeated attempts disagreed. A suite where nearly
every test scores 1.00 for every model measures nothing about relative
capability, and this section makes that visible per test instead of
averaging it away; with a single model there is no spread, so the section
reports instability only.
If `config.yaml` omits `concurrency`, `request_timeout`, or
`max_tokens_default`, `internal/config` fills in `8`, `300s`, and `12000`.

A cell carries a trailing `!` when the model's response was cut off by the

truncated response's score is still whatever the evaluator computed on the
partial text, so a `!` cell needs a closer look: raise
`max_tokens_default` and re-run. `table` and `markdown` print a one-line
legend explaining `!` whenever at least one cell has it. `json` carries the

A cell carries a trailing `!` when at least one of its attempts was cut
off by the token budget (`finish_reason=length`) - for example

partial text, so its score measures the token budget as much as the
model. Attempts that finished normally are therefore the only ones
averaged into the cell's mean and its `[min-max]` range; the truncated
sample is discarded and marked by the `!`. Only when every scored attempt
was truncated does the mean fall back to the partial-text scores - then
the `!` means the whole cell is unreliable and `max_tokens_default` needs
rising before the number can be read as capability. `compare` reuses this
policy, so a truncated sample in one artifact cannot fake a regression.
