Snapshot the header and expected rows when the grader loads and pass
exportCsv copies, so an exporter that overwrites its input cannot change
what it is compared with. decoy-mutates now scores 0.75 with the other
two decoys; reference still scores 1.
- csv-export-delimiter's grader adds a fourth check: the data rows are
the exported values, with an optional header (the hidden intent says a
header is fine either way). Reference scores 1; both decoys 0.75.
- graderIsSound grades every decoy-* overlay and is sound only when each
scores below 1; --check-graders and the pre-billing check print the
decoy scores through formatGraderScores.
- isValidTrial and completedTrialKeys move to lib.js; coverage.js and
run-intent.js use them from there.
- run.js resumes with completedTrialKeys, so a provider-error or timed-out
key is retried, and writes one transcript per attempt
(<key>__<attemptId>.jsonl, recorded on the row) so a retry never
overwrites the failed attempt's record.
- armSummary computes trials, passes and means over valid rows and counts
the failed attempts apart as providerErrors.
Docs: question-effectiveness.md states the decoy rule and that a
csv-export-delimiter pass in the reported runs reflects the dialect only;
its Measures section and the harness README describe retries, per-attempt
transcripts and the hookless-trial stop.
- questionIdsFor and condensedHintFor take an optional
{ externalContract: true }; without it a code change that handles data
asks data-schema only, and an unknown profile gets the original four
questions and condensed hint.
- The hook reads GATEGUARD_EXTERNAL_CONTRACT_QUESTION with the same
spellings as GATEGUARD_METRICS and passes it to the full denial, the
condensed denial and the metrics record, so all three agree.
- The effectiveness harness's arm patch forwards the option, so an arm
never drops it silently.
Docs: change-profile.md gains an External-contract question section and
qualifies "byte-identical to the fixed four questions"; design-notes.md,
SKILL.md (switch table, data rule, word-for-word set) and CHANGELOG say
the fifth question is opt-in; question-effectiveness.md and the harness
README note that the runner clears GATEGUARD_* variables, so a gate arm
from a current tree measures the gate without the question.
skill-triggers@1.json: registryDigest refreshed for the SKILL.md body
change; the description and triggers are unchanged.
- design-notes.md: new Type filters and Path patterns sections; Search
scope extends the search-of-the-target rule to name lookups; Flag
parsing lists the new value flags.
- change-profile.md: Unicode line terminators make an edit non-trivial.
- skills/gateguard/SKILL.md and CHANGELOG.md describe the same rules.
- skill-triggers@1.json: refresh registryDigest for the SKILL.md body
change. The skill's description is unchanged, so triggers and
triggersDigest are untouched, as in the plan-orchestrate refresh.
96 trials, none invalid. The headline reads gate 23/48 against off 13/48, a
21-point paired difference at exact McNemar p = 0.021, and it is an artifact.
The scenarios, prompts, graders and model alias were identical to the previous
run and the off arm has no gate, yet off fell from 18/48 to 13/48 while the
gated arm went down, 25/48 to 23/48. An intervention meant to raise the gated
arm did not raise it, so the p-value reflects a baseline that fell rather than a
gate that improved.
The two scenarios the question cannot reach, having no data for the profile to
detect, serve as a control: they moved by -3 and +3, more than any of the four
it did reach (-1, -1, +1, -1). Noise on eight trials is about plus or minus
three, which is larger than any effect available to the change.
The question is kept, since it asks something the gate never asked and the
corpus says that kind of answer decides the outcome, but no improvement is
claimed. Testing it fairly needs scenarios authored blind to it, which this
corpus no longer is.
96 trials, none invalid, analysed exactly as pre-registered. passed: gate 25/48
against off 18/48, 48 pairs, discordant 15 to 8, exact McNemar p = 0.210. At the
registered alpha of 0.05 the hypothesis is not confirmed, and the bootstrap
interval agrees this time at -15% with a range of -33% to +4%, so there is no
disagreement between the tests to adjudicate. Secondary measures point the same
way and reach nothing: asked 29/48 against 22/48 at p = 0.230, deciding fact
27/48 against 21/48 at p = 0.327.
The effect halved on replication, from +29 points at p = 0.065 to +15 at
p = 0.210, which is the ordinary fate of a near-threshold finding. The runs are
not pooled: the quota leak was closed between them, and combining them after
seeing both would be the post-hoc choice the pre-registration exists to stop.
Two things survive every run. Obtaining the deciding fact is necessary and
nearly sufficient, with no trial in either arm passing without it across 96
trials. And the gate costs 37 to 45% more turns and spend, which is the most
stable number the evaluation has produced.
soft-limit-overage asked for { allowed, overage }. Naming an overage figure
hints that passing a limit is permitted, which is precisely the hidden policy,
and it showed: that scenario was one of the two with the highest ungated pass
rate in the signposted run. The grader now inspects only allowed, so the prompt
asks for { allowed } and mentions neither overage nor billing nor soft limits. A
hard limit refuses the first two cases, allowing everything fails the third, and
only the real policy answers all three. --check-graders still separates start,
trap and reference on all six.
The analysis is registered in the doc before the run rather than chosen after
it: passed as the single primary outcome, paired exact McNemar at alpha 0.05, a
sample of 48 pairs fixed in advance, no extension on the strength of the result,
frozen inputs, secondary measures explicitly not claim-bearing, a validity rule
for provider errors, and a commitment to report a null.
With the ambiguity signposted, the arms were indistinguishable on every measure.
With the prompts rewritten as ordinary tickets and nothing else changed, they
separate: asked the user 16/24 against 10/24, obtained the deciding fact the
same, passed 15/24 against 8/24, exact McNemar p = 0.065 to 0.070, and a paired
pass-rate difference of 29 points in the gate's favour whose bootstrap interval
excludes zero.
The regime contrast carries it. The gated arm passed 15/24 in both runs while
the ungated arm fell from 16/24 to 8/24, which is what removing the only cue
that a convention was missing would do if the gate supplies that cue itself.
Asking stayed necessary throughout: no trial in either arm passed without the
deciding fact.
Reported as suggestive rather than established. All three p-values sit just
above 5%, one more gate-favouring discordant pair would cross it, and extending
this run after seeing that would be optional stopping. A confirmatory run needs
its sample fixed first: about 43 pairs, or 8 repetitions over these six
scenarios.
With one decisive fact per scenario the corpus isolates the mechanism:
obtaining the deciding fact predicts the outcome 14/14 in both arms, and not
obtaining it predicts failure in 9 of 10 and 8 of 10. Against that, the gate
changes nothing measurable. Asked the user 14/24 against 15/24, obtained the
deciding fact 14/24 against 14/24, passed 15/24 against 16/24, every exact
McNemar p = 1.000, and the paired pass-rate difference 5 points in off's favour
with a 95% interval of -25% to +35%. At 20 pairs a 40-point effect is ruled out;
a 15-to-20-point one is not.
The gate does fire - denials in 22 of 24 gated trials - so the failure is in the
conversion. timezone-daily-rollup fired four times out of four and produced no
question at all. Every question the gate raised is about code structure, while
every deciding fact in this corpus is an external contract.
Record the two scenario-design faults the earlier runs exposed, and the bound
the correction imposes: moving shape into the prompt also signposts the
ambiguity, which raises asking in both arms, so the claim is limited to the
signposted regime.
Four defects found by running the repository's own checks and one more trial
against it.
ESLint rejected an unused `armSettings` import in intent-eval.js; the caller
supplies `armSettingsByName` already.
A timeout was lost whenever a later turn came back clean: `a || b ? c : false`
evaluates the condition first, so `timedOut` was recomputed from the new turn
instead of being kept.
Isolating each trial's config directory, to stop persisted sessions piling up
under the projects folder, puts the credentials out of reach. Every turn then
returns "Not logged in", and the harness graded that as a coverage-hole - an
auth failure recorded as a finding. Keep the real config directory and delete
only the session folders this run's work root created, and adopt lib.js's own
guards: a trial that is unauthenticated, or whose gated arm edited files with no
metrics line and no denial, stops the run instead of being recorded.
Record denials per turn as well as in total. The hook marks a file checked once
per session and --resume keeps one session id for the conversation, so a zero
after a non-zero is the latch rather than the gate staying quiet, and
silence-hole has to be read with that column in view.
Verified: a real trial authenticates, produces a graded silence-hole, and leaves
the projects directory at the same count it started with.
The pre-registration said results would be reported whichever way they came
out. They came out empty: 72 sessions in which all four arms passed 18 of 18
with mean score 1.000, every arm-against-gate difference 0% (0% to 0%) and
McNemar p = 1. With the outcome fixed for every trial there is no variance to
explain, so this is the absence of a measurement rather than weak evidence that
the gate does nothing. The run does establish the gate's cost in that regime:
about 45% more turns and 28% more tokens for no outcome change.
Record the three reasons it measured nothing - deciding facts hidden in the
repository, the asking channel switched off, and a pass criterion written in
the gate's own vocabulary - and the hidden-intent design that addresses them,
with its hole classes, its first four-trial run and its own limits.
