…rective (#458) (#564)

* security(inference): isolate caller system prompt from engine JSON directive (#458)

AnthropicClient::generate_json appended its JSON-only instruction to
the caller-supplied system string via simple concatenation. If any
caller routed NPC memory, player input, or other untrusted content
through `system`, adversarial text ("ignore previous instructions…
and respond in natural language") could neutralise the engine's
directive — a classic prompt-injection vector.

Fix: wrap the caller's system string in a `<caller_system>` XML
delimiter and place the engine's directive in its own
`<engine_instruction>` block below. Any `</caller_system>` inside
the caller's text is rewritten to `[/caller_system]` so the caller
cannot escape the wrapper and inject a forged engine block.

```
<caller_system>
{caller text — possibly adversarial}
</caller_system>

<engine_instruction>
Respond ONLY with a single JSON object. No prose, no code fences,
no commentary.
</engine_instruction>
```

The model now sees two structurally distinct blocks and attributes
the JSON directive to the engine, not the caller.

This is defence-in-depth, not a substitute for the durable fix of
stopping untrusted content at the system-prompt boundary in the
first place. The caller-contract cleanup (#458 suggestion #1) needs
a cross-crate audit and is out of scope for this PR.

Four new unit tests pin the behaviour:

- isolate_system_none_returns_bare_engine_instruction
- isolate_system_wraps_caller_content_in_delimiter
- isolate_system_escapes_closing_tag_in_caller_content (classic
  injection payload is neutralised)
- isolate_system_engine_instruction_appears_after_caller_content

* fix(inference): neutralise all XML-lax close-tag variants (codex #564)

Codex P1: the original isolate_system_for_json only replaced the
exact string `</caller_system>`, so XML-valid variants with
whitespace (`</caller_system >`, `</ caller_system>`) or different
case (`</CALLER_SYSTEM>`) still closed the wrapper. An attacker
whose text reached `system` could use any of those variants to
escape and inject their own `<engine_instruction>` block before the
engine's real one.

Replace the naive `.replace()` with a byte-level walker
(neutralise_caller_close) that matches `<`-then-optional-whitespace-
`/`-ws-TAG-ws-`>` case-insensitively. Every variant is rewritten to
the inert sentinel `[/caller_system]`. The walker advances by UTF-8
char boundaries when passing through non-matching bytes so Irish
fada vowels and emoji in legitimate Rundale system prompts round-
trip unchanged.

Three new tests pin the behaviour:

- isolate_system_neutralises_xml_lax_close_variants — eight variants
  (whitespace before/after `/` and tag name, tabs, newlines, full
  uppercase, mixed case) all get rewritten.
- isolate_system_preserves_non_close_angle_brackets — `a < b`,
  `<caller_system_peer>` and similar non-matches pass through.
- isolate_system_preserves_utf8_content — Pádraig Ó
  Flaithbheartaigh and the 👍 emoji survive the byte walk.

…ing leaks

Judging: every cached candidate now has scores from both pinned judges
(grok-4.3 + mistral-large). 29 of 30 cached are fully judged; the
remaining qwen-2.5-72b-instruct is broken on OpenRouter and unscorable.

Parallelism: score_multiaxis grows a `--workers` flag (default 8).
ThreadPoolExecutor over the eligible records — judge calls are the
hot path, all I/O-bound. Wall-time went from estimated 1.5-2 h serial
to ~3 min for 4 judging passes across 14 new candidates.

Reasoning leaks fixed:
- gemini-2.5-pro first cache had every reply truncated mid-sentence
  ("Ah, the night-ter"). max_tokens=200 consumed by internal thinking
  before any content emitted. First-judge scores were nonsense (grok
  2.91, mistral 5.77).
- glm-4.6 first cache had 4/15 replies as meta chain-of-thought
  ("1. **Deconstruct the Persona:**..."). Mistral was lenient enough
  to score it 9.29; grok flagged it down to 4.43. 4.86-point judge
  disagreement was the smoking gun.

eval_lib.call_chat already auto-disables reasoning for known
reasoning-class models via REASONING_MODEL_PREFIXES, but the
suppression dict was hardcoded to `{"enabled": false}`. Google rejects
that with HTTP 400; only `reasoning: {effort: "low"}` works. Added a
per-provider `_default_reasoning_for(model_id)` so the dict matches
what each provider accepts.

Added prefixes: google/gemini-2.5-pro, google/gemini-3, z-ai/glm-4.6.

After re-cache + re-judge, both candidates land in the normal range
with cross-judge spread under 1.0:
  gemini-2.5-pro  grok=8.12  mistral=8.97  Δ=0.85
  z-ai/glm-4.6    grok=7.89  mistral=8.76  Δ=0.87

Headline standings (grok-4.3 / mistral-large):
  openai/gpt-5.5            8.75 / 9.05    ← high-tier top
  openai/gpt-5.4            8.55 / 9.17    ← mistral's #1 high
  openai/gpt-5.4-mini       8.63 / 9.03    ← mid-tier top
  anthropic/claude-opus-4.7 8.64 / 9.05
  anthropic/sonnet-4.6      8.53 / 9.13
  mistral-medium-3.1        8.59 / 9.09

Also stripped earlier n=1 outliers from the leaderboard data:
  - kimi-k2.5 single-record rows in early mid-tier sweeps
  - qwen-2.5-72b-instruct single-record row (provider broken)

Leaderboard page regenerated (quality=57 rows, perf=5, cached=30,
unjudged=1).

* feat(eval): rundale-bench ELO mode (pairwise judge)

The absolute 5-axis rubric saturated near ceiling — gpt-oss-120b:free
scored 4.82/5 with no headroom for stronger models to differentiate.
Pairwise ELO replaces it as the dialogue-ranking primary.

Changes:
- judge_pairwise_v1.json — new pinned judge config (qwen3-235b on
  OpenRouter, rubric_sha256 b5664f96…dc7c0), pairwise rubric requiring
  one-sentence reason per verdict.
- grade.py::grade_pairwise — judge picks A | B | tie + reason.
  Non-Latin script in one reply auto-disqualifies that side (judge
  can't be trusted to enforce that consistently).
- rundale_bench.py --mode elo — repeated --target flags, runs every
  candidate over the dialogue slice once (cached replies), schedules
  one pairwise match per (a, b) pair per prompt with A/B position
  randomized to absorb first-position bias. K=32 → K=16 after 50
  matches per candidate. Bootstrap 5/95 CI via 500 resamples.
- test_grade.py — 5 new pairwise tests (winner, tie, invalid winner,
  non-Latin auto-DQ, rubric tamper). 27/27 pass.

Smoke (3 candidates × 10 prompts × 1 pair per prompt = 60 calls,
~$0.0013, 346s):

  1646.2  [CI 1598.6–1694.0]  qwen/qwen3-235b-a22b-2507
  1497.1  [CI 1437.0–1561.2]  openai/gpt-oss-120b:free
  1356.6  [CI 1306.3–1399.8]  mistralai/mistral-small-24b-instruct-2501

290-point spread with non-overlapping CIs between top and bottom.

* feat(eval): cache_dialogue_replies + rubric_lab for offline rubric tuning

Goal: iterate the judging rubric without re-querying candidate models.
Generate replies once, cache to JSON, then prototype rubrics offline.

Tools:
- cache_dialogue_replies.py: --target ... --prompts N, writes
  docs/proofs/rundale-bench/dialogue_samples_<UTC>.json with one record
  per (candidate, prompt) including reply, usage, latency, error.
- rubric_lab.py: loads a cached samples file + a rubric text file,
  scores all samples in absolute (1-N) or pairwise (ELO) mode, prints
  per-candidate distribution. Zero candidate spend per iteration —
  only judge cost.

Three cache snapshots committed as evidence:

  003651Z.json  6 free OpenRouter candidates × 15 prompts
                — 65/90 useful (gemma-4 0/15, qwen-next 6/15 throttled)
                — kept as baseline showing why free tier is unreliable

  004513Z.json  6 paid cheap (<$1/M out) × 15 prompts
                qwen3-235b, mistral-small-24b, gemma-3-27b, phi-4,
                deepseek-v3.2, gpt-oss-120b
                90/90 ok, $0.0009, 205s

  005721Z.json  6 mid-tier ($1-$5/M out) × 15 prompts
                claude-haiku-4.5, gpt-4o-mini, gemini-2.5-flash,
                mistral-large-2512, kimi-k2.5, grok-3-mini
                90/90 ok, 324s

245 useful samples across 17 distinct candidates total. Rubric
iteration now an offline activity that costs nothing per pass.

* feat(eval): 12-candidate ELO sweep with mistral-large judge

Kimi 2.6 attempted as judge but failed: reasoning model emits all
output in `reasoning` field, content is null, every match returned
empty → all ties. Same problem hit z-ai/glm-4.7. Switched to a
non-thinking judge.

mistral-large-2512 ($0.50/$1.50, 1-2s/call) judged 816 pairwise
matches over the 12 paid OpenRouter candidates × 15 dialogue prompts:

  1898.9  qwen/qwen3-235b-a22b-2507
  1768.4  anthropic/claude-haiku-4.5
  1705.0  google/gemma-3-27b-it
  1682.6  mistralai/mistral-large-2512    (judge self-bias)
  1622.8  moonshotai/kimi-k2.5            (n=11 only; reasoning empty)
  1484.9  x-ai/grok-3-mini
  1473.3  deepseek/deepseek-v3.2
  1356.8  openai/gpt-oss-120b
  1340.9  google/gemini-2.5-flash
  1305.2  mistralai/mistral-small-24b-instruct-2501
  1242.6  openai/gpt-4o-mini
  1118.6  microsoft/phi-4

780-point top-to-bottom spread. Headline: claude-haiku-4.5 is the
standout cheap-tier dialogue model; phi-4 is unsuitable. qwen3-235b
top spot is suspect — it was the prior judge pin so may carry
training bias toward its own style.

Tooling updates:
- rubric_lab.py: per-match progress log (flush=True), max_tokens=2000
  for judge calls (reasoning models need budget), empty-content guard
  that raises "reasoning model truncated?" instead of silent 0-score.
- Documented reasoning-class judge incompatibility in leaderboard
  caveats — until call_chat handles `reasoning` fallback, kimi-* and
  glm-* are unusable as judges OR candidates.

* chore(eval): justfile recipes for rundale-bench workflows

Wraps the tasks executed this session so they're rerunnable without
remembering target-spec strings, env-loading boilerplate, or rubric_lab
flags. Recipes:

Correctness gates (no API spend):
- test        — run grade.py unit tests
- manifest    — rebuild MANIFEST.json after slice edits
- split       — re-run holdout split + manifest

Single-target probes:
- intent target [limit=20]    — deterministic intent grading
- dialogue target [judge limit] — absolute 5-axis rubric
- bench target [judge limit]   — --slice all sweep

Multi-target ELO:
- elo "spec_a spec_b ..." [limit=10] — in-bench --mode elo, fresh replies

Cached-reply workflow (rubric iteration, no candidate spend):
- cache-cheap [prompts=15]   — 6 paid-cheap fleet (~$0.001, ~3min)
- cache-mid [prompts=15]     — 6 mid-tier fleet (~$0.05)
- cache-all [prompts=15]     — both, back to back
- cache targets="..." [prompts]
- elo-from-cache samples [rubric judge output] — pairwise over cache
- absolute-from-cache samples rubric [axis_scale judge output]

Convenience:
- list-samples   — show cached sample files
- sample-stats   — n_samples / ok / empty / cost per cache

Run from repo root with `-f`:
    just -f parish/testing/rundale-bench/justfile <recipe> ...

ENV_FILE points at <repo>/.env; recipes source it before invoking python
so OPENROUTER_API_KEY (and equivalents) reach call_chat. Default judge
is mistral-large-2512 (non-thinking, ~$0.001/call, 1-2s wall) — override
with `judge=...` per recipe.

* feat(eval): multi-axis 0-10 scoring + just recipe

Per-axis 0-10 dialogue scorer over cached samples. Five axes (character,
authenticity, language, responsiveness, craft) + a judge-emitted total —
complements pairwise ELO by exposing *why* a candidate ranks where it does.

- `score_multiaxis.py` — judge emits one integer per axis (0-10) plus a
  float `total`. Per-record + per-candidate aggregates written to JSON.
  Default judge `mistralai/mistral-large-2512`, calibration anchors
  baked into the rubric (0/3/6/8/10 gradient).
- `justfile multiaxis` recipe — accepts positional args only (samples,
  judge, rubric); output is auto-stamped to docs/proofs/rundale-bench/.
  Earlier draft accepted `output=...` as a named arg which just silently
  parses as the next positional, sending `--judge-model 'output=...'` and
  earning HTTP 400 from every call. Removed.

Evidence: ran both cached sweeps end-to-end. 76+88 calls, ~$0 spend
(well under mistral-large's $0.50/$1.50 floor). Three top candidates
agree with the ELO ranking — gemma-3-27b / qwen3-235b / claude-haiku-4.5
cluster within 0.10 of each other, mistral-large self-bias still present.

* feat(eval): qwen3-max flagship probe + aggregator bug fix

Added qwen/qwen3-max (Chinese flagship, $1.20/$6 per M, non-reasoning)
to the multi-axis 0-10 leaderboard. Result: 9.03 total — ties
gemma-3-27b and edges qwen3-235b by 0.03, well inside rubric noise.
~17× the cost of qwen3-235b for zero meaningful gain on this slice.

Also fixed an aggregator bug in score_multiaxis.py: judge-call errors
(HTTP 503, rate-limit drops, schema-parse failures) were contributing
zeros to per-candidate means. A first qwen3-max pass hit two 503s after
4 retries each, pulling its headline mean to 7.87 — nonsense for a
flagship. Errored records still land in `per_record` for inspection
but no longer skew aggregates.

* feat(eval): grok-4.3 judge re-sweep + deepseek-v4-pro candidate

Re-judged all 4 cached sample sets with x-ai/grok-4.3 (non-reasoning,
$1.25/$2.50 per M) to test judge sensitivity. 193 calls, 0 errors,
~43 min, ~$0.40 total.

Added deepseek/deepseek-v4-pro to the candidate roster (deepseek's
current flagship, $0.435/$0.87 per M). Surprise result: v4-pro scores
*worse* than v3.2 (7.77 vs 7.91) on 1820 Irish dialogue — likely from
heavier reasoning/structure RLHF that hurts persona fidelity.

Judge findings:
- 2.36-point top-to-bottom spread vs 0.81 under mistral-large. Grok
  discriminates harder.
- Top-3 robust across judges: qwen3-max / mistral-large / qwen3-235b
  within 0.06 of each other under both. Real ceiling for this slice.
- grok-3-mini lifts to #4 — same judge-family bias as previous sweeps.
  Discount by ~0.3 mentally.
- gpt-4o-mini drops 1.67 points under stricter grok judge (8.27 → 6.60)
  — biggest cross-judge gap of any candidate.

kimi-k2.6 tried as judge first; failed 70%+ of calls (reasoning tokens
ate the max_tokens budget before content emission, even at 8K). Added
a reasoning-field fallback to eval_lib's `call_chat` so short
reply→content-empty cases recover (k2.6 still not viable as judge
under JSON-schema mode).

Bumped score_multiaxis _JUDGE_MAX_TOKENS 2000 → 8000 to give thinking
judges headroom. Records kimi failure as evidence:
multiaxis_20260514T175833Z.json (10 of 14 errors).

* feat(eval): TTFT/tok-s/JSON-compliance probe + gemma-4/qwen-2.5 candidates

Adds a streaming-mode perf probe complementing the rubric-quality
bench. Three new dimensions per candidate:
  - ttft_ms (time-to-first-content-token via stream:true)
  - tok/s   (completion_tokens / generation seconds)
  - json compliance rate, both free-form and schema-enforced

Implementation:
- eval_lib.py grows `call_chat_streaming(target, …)` that parses SSE,
  records TTFT on first content delta, accumulates token usage from the
  final usage line. Also retries on body-level 502/503 (xAI grok-4.3
  capacity errors land inside 200 OK responses).
- bench_perf.py runs the probe and dumps perf_<UTC>.json with per-call
  records + per-candidate medians + p90s.
- justfile adds `perf` (single target) and `perf-many` (pre-quoted
  --target … flags) recipes.

Initial measurements on 4 candidates (10 prompts each):

  candidate                  TTFT p50  Total p50  tok/s p50  JF%  JS%
  qwen/qwen3-235b-a22b-2507     363ms     1696ms     54.2   100% 100%
  google/gemma-3-27b-it         380ms     2328ms     37.9   100% 100%
  google/gemma-4-31b-it        1160ms     3214ms     21.9   100% 100%
  qwen/qwen-2.5-72b-instruct     0ms     5242ms      0.0    10%  90%

qwen3-235b is fastest across all three perf axes AND tied for top-3
quality under both judges. Strong default.

gemma-4 is slower than gemma-3 in every dimension (TTFT 3×, tok/s ~½)
AND scores 0.23 lower under the grok-4.3 judge. Newer is not an upgrade.

qwen-2.5-72b-instruct returns "Provider returned error" 400 from
OpenRouter on 14/15 cache calls; streaming all errored. Free-form JSON
10%, schema 90%. Different provider routing required before this
candidate can be fairly evaluated.

* chore(eval): cache dialogue replies for 14 new candidates (high + mid tier)

Cached 15 dialogue replies for each candidate to enable offline rubric
judging without re-spending. Judging deferred — user wants more samples
collected before re-judging the full set.

High tier (6, $0.x to $5/$30 per M):
  - anthropic/claude-opus-4.7
  - anthropic/claude-sonnet-4.6
  - openai/gpt-5.5
  - openai/gpt-5.4
  - google/gemini-2.5-pro
  - x-ai/grok-4.3

Mid tier (8):
  - meta-llama/llama-3.3-70b-instruct
  - meta-llama/llama-4-maverick
  - meta-llama/llama-4-scout
  - openai/gpt-5.4-mini
  - mistralai/mistral-medium-3.1
  - z-ai/glm-4.6
  - nousresearch/hermes-4-405b
  - amazon/nova-pro-v1

All 210 calls returned non-empty replies. Cache files:
  - dialogue_samples_20260514T221845Z.json (high tier, 90 samples, ~6min)
  - dialogue_samples_20260515T181515Z.json (mid tier, 120 samples, ~6min)

Brings the candidate pool to 28 unique models cached for dialogue. Ready
for a multi-judge re-sweep when bench iteration resumes.

* feat(eval): static leaderboard page for rundale-bench

Aggregates every multiaxis_*.json + perf_*.json + dialogue_samples_*.json
into a single static HTML page (`docs/proofs/rundale-bench/leaderboard.html`).
Open in any browser — no server required.

Sections:
  - Stat header (cached / judged / unjudged / judge count / row counts)
  - Quality table (sortable + filterable by candidate or judge)
  - Perf table (TTFT / total / tok/s / JSON compliance pills)
  - Judge coverage matrix (✓ / · per candidate × judge)
  - Unjudged backlog list

Vanilla JS, no deps. Dark theme by default with auto-light via
prefers-color-scheme. Pure DOM rendering with HTML escaping — no
innerHTML on untrusted strings.

Regenerate after any new run with:
  just -f parish/testing/rundale-bench/justfile leaderboard

Current state baked into the page: 30 cached candidates, 16 judged,
14 unjudged, 3 distinct judges, 31 quality rows + 5 perf rows.

* feat(eval): re-cache kimi-k2.5 sans reasoning; add cross-judge average view

eval_lib gains a `reasoning` kwarg on call_chat that gets passed through
to OpenRouter. When a target model is known to be reasoning-class
(kimi-k2.5/k2.6/k2-thinking, glm-4.7, o1/o3/o4, deepseek-r1, opus 4.7,
sonnet 4.6) the default switches to `{"enabled": false}` so cached
dialogue replies are the in-character answer rather than truncated
thought process.

Result for kimi-k2.5: 0/15 valid replies before → 15/15 valid now,
44.5 s wall vs prior timeouts. Judged with both pinned judges:
  grok-4.3        → 8.56 total (n=15)  -- #4 in grok ranking
  mistral-large   → 8.96 total (n=15)  -- #4 in mistral ranking

Both rank kimi-k2.5 #4 in cross-judge consistent way (between
qwen3-235b and claude-haiku-4.5).

Static leaderboard page now exposes an "average" view in the judge
selector: per-candidate mean across each distinct judge it was scored
by. Only emitted when ≥2 judges agree on coverage (otherwise the
"average" of one row is just the row).

Removed the failed kimi-k2.6 judging run
(multiaxis_20260514T175833Z.json) — kept solely as a failure-mode
artifact, no longer useful now that the broader story is documented
in the leaderboard md.

Coverage matrix dropped its hardcoded 3-column layout for a dynamic

* feat(eval): judge all 14 high+mid candidates, parallelize, fix reasoning leaks

Judging: every cached candidate now has scores from both pinned judges
(grok-4.3 + mistral-large). 29 of 30 cached are fully judged; the
remaining qwen-2.5-72b-instruct is broken on OpenRouter and unscorable.

Parallelism: score_multiaxis grows a `--workers` flag (default 8).
ThreadPoolExecutor over the eligible records — judge calls are the
hot path, all I/O-bound. Wall-time went from estimated 1.5-2 h serial
to ~3 min for 4 judging passes across 14 new candidates.

Reasoning leaks fixed:
- gemini-2.5-pro first cache had every reply truncated mid-sentence
  ("Ah, the night-ter"). max_tokens=200 consumed by internal thinking
  before any content emitted. First-judge scores were nonsense (grok
  2.91, mistral 5.77).
- glm-4.6 first cache had 4/15 replies as meta chain-of-thought
  ("1. **Deconstruct the Persona:**..."). Mistral was lenient enough
  to score it 9.29; grok flagged it down to 4.43. 4.86-point judge
  disagreement was the smoking gun.

eval_lib.call_chat already auto-disables reasoning for known
reasoning-class models via REASONING_MODEL_PREFIXES, but the
suppression dict was hardcoded to `{"enabled": false}`. Google rejects
that with HTTP 400; only `reasoning: {effort: "low"}` works. Added a
per-provider `_default_reasoning_for(model_id)` so the dict matches
what each provider accepts.

Added prefixes: google/gemini-2.5-pro, google/gemini-3, z-ai/glm-4.6.

After re-cache + re-judge, both candidates land in the normal range
with cross-judge spread under 1.0:
  gemini-2.5-pro  grok=8.12  mistral=8.97  Δ=0.85
  z-ai/glm-4.6    grok=7.89  mistral=8.76  Δ=0.87

Headline standings (grok-4.3 / mistral-large):
  openai/gpt-5.5            8.75 / 9.05    ← high-tier top
  openai/gpt-5.4            8.55 / 9.17    ← mistral's #1 high
  openai/gpt-5.4-mini       8.63 / 9.03    ← mid-tier top
  anthropic/claude-opus-4.7 8.64 / 9.05
  anthropic/sonnet-4.6      8.53 / 9.13
  mistral-medium-3.1        8.59 / 9.09

Also stripped earlier n=1 outliers from the leaderboard data:
  - kimi-k2.5 single-record rows in early mid-tier sweeps
  - qwen-2.5-72b-instruct single-record row (provider broken)

Leaderboard page regenerated (quality=57 rows, perf=5, cached=30,
unjudged=1).

* feat(eval): fill perf table for 26 remaining candidates; dedupe by latest

Ran bench_perf on 4 parallel shards (~6-7 candidates each). 760 calls
across 26 new candidates, ~10 min wall, <\$0.001 spend. Combined with
the original 4-candidate probe, the perf table now covers every cached
candidate.

build_leaderboard_page now keeps only the latest perf measurement per
candidate so smoke runs do not pollute the table. (Earlier 3-prompt
gemma-4 smoke was overwriting the 10-prompt sweep result.)

Notable perf findings:
- gpt-5.4-mini fastest at the top of mid: TTFT 561 ms / 75.5 tok-s
- gpt-5.5 surprisingly slow: TTFT 2242 ms / 60 tok-s — pay flagship
  premium and wait twice as long as gpt-5.4-mini
- glm-4.6 total p50 = 16883 ms (huge tail) — reasoning still active
  for some calls despite suppression; investigate before recommending
- phi-4 free-form JSON 0% / schema 100% — strict schema is mandatory
- mistral-medium-3.1 free-form JSON 10% / schema 100% — same shape

qwen-2.5-72b-instruct re-cache attempt forcing provider.order=
["DeepInfra", "Together"] recovered some replies (4/15) but still
flaky; not viable as a judge or candidate via OpenRouter under any
provider sort/order I tried. Documented as unjudged.

Final state: 29/30 cached candidates judged, 30/30 perf-measured.

* fix(eval): address gemini-code-assist review feedback

1. ELO match recording for errored candidates (HIGH).
   When candidate A errored mid-sweep, `matches.append((b, a, 0.0))`
   recorded a loss against B (the winner) instead of A. Bootstrap CI
   inherited the same flip. Fixed to canonical `(a, b, 0.0)` ordering
   so score_a=0.0 correctly means A lost.

2. Null-safe judge `reason` strings.
   `str(out.get("reason", ""))` returns the literal string "None" when
   the judge emits `{"reason": null}` (some providers do this even
   with strict json_schema). Replaced with `str(out.get("reason") or
   "")` everywhere — grade.py, rubric_lab.py, score_multiaxis.py.

3. Target identity collision in ELO mode.
   `replies[(t.model, prompt_id)]` collided when two `--target` flags
   shared the same `model` string (e.g. comparing the same model
   across providers / base_urls). Switched to `model@base_url` as the
   canonical id and added a startup check that rejects duplicates.

4. Bootstrap CI now mirrors dynamic K.
   Main accumulator drops K from 32 → 16 after 50 matches per
   candidate. _bootstrap_ci was using k_initial constant for every
   match, so late-resampled matches moved ratings more than reality.
   Bootstrap now tracks match counts per iteration and applies the
   same threshold.

All 27 grade.py unit tests still pass.

Across 38+ observed demo turns (cycles 1-5) the auto-player emitted
exactly 1 movement action. Per TODO #30's audit, the action grammar is
fine — `go to X` resolves to `Move` via the input parser landed in
round 4. The blocker is prompt shape:

1. Movement was 1 of 4 few-shot examples in `build_demo_system_prompt`
   with no explicit cadence rule.
2. "travel widely" in `mods/rundale/demo-prompt.txt` was buried mid-
   sentence and read as stylistic, not directive.
3. The CRITICAL paragraph listed `"go to Z"` among forbidden command-
   form intents — a direct contradiction that biased the model away
   from the correct movement command shape.

Fix carves movement out as a first-class action:

- `demo-prompt.txt`: new top-level MOVEMENT paragraph citing the
  "You can go to: ..." surface, the 3-5-turn cadence, and the three
  canonical verbs. CRITICAL paragraph rewritten so `go to X` /
  `walk to X` / `head to X` is the documented exception to the
  no-command-form rule (other meta-commands like "ask about X" stay
  forbidden).
- `build_demo_system_prompt`: new MOVEMENT CADENCE section with the
  3-5-turn rule + "if only one location in last 5 turns, move next"
  override. Few-shots expanded 4 → 6 examples, 3 of them now
  movement actions covering all three verbs.

Live transcript via parish-engine --headless --script proves the
engine resolves both `go to the forge` and `go to the holy well` as
`result:"moved"` with proper narration + minutes-elapsed — confirming
the prompt is the load-bearing lever, not the schema. LLM-emits-
movement evidence requires a follow-up `just demo` cycle against a
real model; documented in acceptance-criteria.md as a post-merge
observable.

* fix(demo): direct auto-player to move when NPCs here: none (TODO #12)

Cycles 2, 7, and 9 of the demo audit caught the auto-player stranded
at empty locations — 4 turns at The Mill after Brendan + Cormac
departed, 18 sterile turns at the abandoned Hedge School. The LLM-as-
player kept speaking aloud ("I'll wait here by the mill", "Sittin'
here, I notice a book half-open on the table") instead of moving. The
MOVEMENT CADENCE directive from TODO #1/#30 handles the general "after
3-5 turns, move" rhythm but not the specific signal NPCs here: none.

Add a WHEN ALONE section to build_demo_system_prompt that quotes the
verbatim "NPCs here: none" cue, closes the speech-at-nobody loophole
explicitly, and pins the next action to one of the three movement
verbs already taught in the cadence block. Pin the header, the cue,
and the move-only instruction in demo_system_prompt_carries_alone_move_directive
so a future refactor cannot drop the section silently.

A companion engine-side fix (TODO #46 — surface a system response
when the player speaks at an empty location) is deferred so the
impact of this directive can be measured first.

* ci: retrigger after Actions incident resolved

* ci: retrigger after Rust quality gate timeout (cache cold)

* test(inference): route default-frequency-penalty test through Interactive lane

#1127's test_inference_queue_send_default_omits_frequency_penalty sent on
the Background lane but received from the Interactive receiver (`irx`).
The message went to `_brx`, which nobody reads, so `irx.recv()` blocked
indefinitely. PR #1127's CI runs were both cancelled before the test
could surface the hang, and the merge to main stalled the Rust quality
gate at the 30-minute timeout on every subsequent PR.

Swap `InferencePriority::Background` to `Interactive` so the send lands
on the lane `irx` actually drains. Add a comment pointing future readers
at the failure mode so the lane-mismatch trap isn't re-laid.
