quietset 0.12.0

Filter datasets by label stability across evaluators, budgets, seeds, and models
Documentation

quietset

CI crates.io docs.rs

A model-agnostic stability filter — keeps samples whose labels or scores remain consistent across evaluators, budgets, seeds, and model checkpoints.

quietset is not a model trainer, annotation platform, or image-quality auditor. It is a small stability-filtering primitive designed to compose with other tools.

Note: quietset measures stability, not correctness. A sample can score high because evaluators consistently agree on a wrong answer. Use gold_label-based reliability or --decision-score lcb to add evidence-based conservatism.

Use cases

Game AI / search training data

Multiple engines, depths, or seeds evaluate the same position. Keep only positions where the evaluation is stable — consistent labels and scores regardless of search parameters.

quietset score positions.jsonl --profile game-ai > stable_positions.jsonl
quietset stable-wrong-risk positions.jsonl  # flag positions stable evaluators consistently mis-label

LLM judge pipelines

Multiple judge models or prompts evaluate the same response. Keep only responses where judges consistently agree, using Wilson LCB to guard against low-n flukes.

quietset score judge_evals.jsonl --profile llm-judge > reliable_evals.jsonl
quietset calibrate judge_evals.jsonl --target-precision 0.95 --decision-score lcb

Synthetic / simulation data

Scores or rewards vary across seeds, budgets, or model checkpoints. Keep samples whose quality signal is robust to these variations.

quietset score runs.jsonl --profile simulation > robust_samples.jsonl
quietset audit robust_samples.jsonl --json | jq '.seed_sensitive[:5]'

Output formats

Output conventions differ by command — deliberately, since some commands are built for human inspection and some for pipeline composition (see select and --embed-stats). There is no single unified format; use this table to know what to expect from each command before scripting against it:

Command Default Flag(s) Notes
score JSONL --output-format jsonl|csv csv is a terminal/export format — see below
filter JSONL (pass-through) none Always echoes original input lines unchanged
select JSONL (pass-through) none Always echoes original input lines unchanged
reliability JSONL none One object per evaluator, plus an optional trailing kappa/alpha line
active-review JSONL none One object per ranked sample
recommend JSONL --text Only command where JSONL is the default and text is the opt-in
stable-wrong-risk single pretty JSON object none
calibrate single pretty JSON object --output-format json|csv csv is a single header row + one data row
summary text --json (single pretty object)
explain text --json (single pretty object)
compare text --json (single pretty object)
audit text --json (single pretty object)
policy text table --output-format text|json|csv (legacy --json still works as an alias for json) json is JSONL, one line per swept threshold; csv has fixed columns (empty cells when no gold_label)

CSV is a dead end for piping. score --output-format csv, calibrate --output-format csv, and policy --output-format csv exist purely for spreadsheets/BI tools. No other quietset command can parse CSV back in (filter/summary/explain/compare/audit/select/ recommend/active-review all expect JSONL StabilityReports; stable-wrong-risk/calibrate/ reliability/policy expect JSONL Observations). If you plan to pipe score's output into another quietset command, use the default jsonl, not csv.

Input JSONL format

{"sample_id":"a","label":"win","score":0.91,"evaluator_id":"m1","budget":4,"seed":1,"gold_label":"win"}
{"sample_id":"a","label":"win","score":0.88,"evaluator_id":"m1","budget":8,"seed":1,"gold_label":"win"}
{"sample_id":"b","label":"win","score":0.52,"evaluator_id":"m1","budget":4,"seed":1}
{"sample_id":"b","label":"loss","score":-0.10,"evaluator_id":"m2","budget":8,"seed":2}

All fields except sample_id are optional. gold_label provides the known-correct label for a sample; when present, the reliability command uses it as ground truth instead of majority vote.

Output JSONL format

Key fields in the output (optional fields are omitted when not computable):

{
  "sample_id": "a",
  "n_observations": 2,
  "majority_label": "win",
  "label_agreement": 1.0,
  "label_agreement_lcb": 0.342,
  "label_margin": 1.0,
  "label_entropy": 0.0,
  "score_mean": 0.895,
  "score_std": 0.015,
  "score_mad": 0.015,
  "score_iqr": 0.030,
  "confidence": 0.40,
  "adjusted_stability_score": 0.782,
  "stability_score": 0.97,
  "decision": "keep",
  "components": {
    "label": 1.0,
    "score_consistency": 0.985
  }
}

Optional fields are omitted when not computable (e.g. label_agreement_lcb only appears when labels are present; score_mad / score_iqr require at least two numeric scores).

Stability score

The stability_score is a value in [0.0, 1.0]:

  • 1.0 = highly stable
  • 0.0 = highly unstable

It is the weighted mean of available sub-scores (all in [0.0, 1.0]):

Component Value
label_agreement fraction of observations with the majority label
score_consistency 1 - normalized_score_std
budget_robustness 1 - budget_sensitivity
seed_robustness 1 - seed_sensitivity
model_agreement label agreement across models
evaluator_agreement label agreement across evaluators
score_sign_agreement fraction of numeric scores sharing the majority sign — weight defaults to 0 (excluded); opt in with --weight-score-sign (--profile game-ai enables it at ×2 by default)

Missing dimensions (e.g. no labels, no budgets) are excluded from the mean. Single observations receive stability_score = 0.5 (review by default).

Additional diagnostic fields on StabilityReport:

Field Meaning
label_margin (majority_count - runner_up_count) / total. 0.0 = perfectly split
label_entropy Normalised Shannon entropy [0, 1]. 1.0 = uniform label distribution
label_agreement_lcb Wilson confidence interval lower bound of label_agreement. More conservative than raw label_agreement — guards against low-n coincidences.
score_mad Median absolute deviation of numeric scores. More robust to outliers than score_std.
score_iqr Interquartile range (Q3 − Q1) of numeric scores.
score_sign_agreement Fraction of numeric scores sharing the majority sign (negative / zero / positive). Domain-aware complement to score_std/score_mad/score_iqr for signed, zero-centered scores (chess/shogi-style eval): [+0.01, -0.01] reads as near-perfectly stable by magnitude alone but is a coin-flip on sign. Always computed but excluded from stability_score by default (--weight-score-sign 0); pass --weight-score-sign <f> to make it contribute. --profile game-ai enables it at ×2 by default — for every other profile, this stays a purely informational field unless explicitly weighted.
budget_slope Score trend as budget increases (positive = converges upward)
confidence n / (n + k) — how much to trust the score given evidence count
adjusted_stability_score stability * confidence + 0.5 * (1 - confidence)

Components field

Each sub-score is also exposed in components so you can see why a sample was scored as it was:

{
  "sample_id": "a",
  "stability_score": 0.91,
  "decision": "keep",
  "components": {
    "label": 1.0,
    "score_consistency": 0.96,
    "budget_robustness": 0.88
  }
}

Use --weight-* flags to tune individual dimensions, or use --profile (see Profiles).

Profiles

Apply a use-case preset with --profile instead of tuning weights manually. Explicit --weight-* and --decision-score flags always override the preset.

Profile Weight changes Default decision-score
llm-judge evaluator ×2, model ×2 lcb
simulation budget ×2, seed ×2 adjusted
game-ai budget ×2, seed ×2, score_sign ×2; min-observations 4, min-budgets 2, min-seeds 2, min-evaluators 2 lcb
benchmark label ×2, evaluator ×1.5 raw
# LLM judge preset (equivalent to --weight-evaluators 2 --weight-models 2 --decision-score lcb)
quietset score input.jsonl --profile llm-judge > scored.jsonl

# Override one weight from the preset
quietset score input.jsonl --profile simulation --weight-budget 3.0 > scored.jsonl

Confidence and adjusted score

confidence = n / (n + k) where k defaults to 3.0.

n_observations confidence (k=3)
1 0.25
2 0.40
5 0.63
10 0.77
20 0.87

adjusted_stability_score = stability_score * confidence + 0.5 * (1 - confidence)

A sample with stability_score = 0.95 but only 2 observations gets adjusted_stability_score ≈ 0.68 — unlikely to reach the keep threshold (0.85) without more evidence.

Use --use-adjusted-score to make decisions based on the adjusted score. Use --confidence-k to tune the convergence speed.

Minimum requirements for Keep

High stability does not guarantee sufficient evidence. Use --min-*-keep to demote underevidenced samples to Review:

quietset score input.jsonl \
  --min-observations-keep 3 \
  --min-evaluators-keep 2 \
  --min-seeds-keep 2 \
  > scored.jsonl

Decisions

By default, decisions use stability_score. Five decision modes are available:

Flag Alias Score used Behaviour
--decision-score raw (default) stability_score Raw stability. Fast; can overfit small-n.
--decision-score adjusted --use-adjusted-score adjusted_stability_score Penalises low-evidence samples proportionally.
--decision-score lcb --use-lcb-score label_agreement_lcb (label) Wilson LCB — most conservative. A 2/2 label match gives LCB ≈ 0.34 at 95% confidence, so it will not be kept without more evidence.
--decision-score gold-weighted stability_score (label component reliability-weighted) Replaces the raw majority label vote with a gold_label-reliability-weighted vote. Falls back to identical behaviour as raw when no gold_label is present anywhere in the input.
--decision-score latent-truth stability_score (label component EM-weighted) Replaces the raw majority label vote with a Dawid-Skene EM-estimated vote — infers per-evaluator reliability from disagreement patterns alone, no gold_label required. Falls back to identical behaviour as raw when the input has fewer than 2 distinct evaluators or labels. Adds latent_truth_label, latent_truth_confidence, latent_truth_label_distribution, majority_latent_conflict, evaluator_effective_n, correlated_evaluator_warning, latent_truth_converged, latent_truth_iterations, latent_truth_convergence_delta, latent_truth_demotion_reason to the output. latent_truth_confidence is EM's fitted posterior, which saturates toward 0/1 with only a few evaluators and can be confidently wrong when evaluators are correlated in their bias — it is not a correctness guarantee. evaluator_effective_n/correlated_evaluator_warning diagnose that same risk (Kish design effect on pairwise-correlated evaluator errors) but can only detect it when other evaluators reveal a correlated block's shared deviation — if the block captures the EM consensus outright, no warning fires; it's a self-consistency diagnostic, not an independent correctness check. latent_truth_converged is false when the EM loop exhausted its iteration cap without settling (latent_truth_iterations hits the cap, latent_truth_convergence_delta stays above the convergence epsilon) — the posterior is still valid but less certain; the same value applies to every sample scored in that batch, since EM runs once per batch.

MinRequirements are always applied after the threshold comparison. For --decision-score latent-truth, three additional opt-in, default-off safety demotions apply after that: --demote-on-correlated-warning (demotes when correlated_evaluator_warning fires), --min-evaluator-effective-n <f64> (demotes when evaluator_effective_n falls below this absolute value, independent of the relative 70%-of-nominal warning above), and --demote-on-non-convergence (demotes when latent_truth_converged is false). Each only ever demotes KeepReview — never further to Drop, since these are uncertainty signals, not certainty-of-wrongness signals — and never touches stability_score itself. When a demotion fires, latent_truth_demotion_reason names which condition (correlated_evaluator_warning, evaluator_effective_n_below_minimum, or latent_truth_not_converged, in that priority order if more than one fires at once). Available on score and stable-wrong-risk; no-op on calibrate/policy/compare --policy-after, which compare raw scores directly rather than reading decision.

Condition Decision
score >= 0.85 keep
score <= 0.40 drop
otherwise review

The defaults — 0.85 keep, 0.40 drop — were chosen to leave a deliberate review band. 0.85 requires strong agreement across most observations before a sample is trusted; 0.40 only rejects samples with clear, consistent disagreement. Everything between is uncertain enough to warrant human review rather than an automatic decision. For high-stakes training data, raise --keep-threshold to 0.90–0.95. For noisy synthetic data where volume matters more than purity, lower it to 0.75–0.80.

Configurable via --keep-threshold and --drop-threshold. Use --confidence-level to tune the Wilson LCB confidence level (default 0.95).

The --use-adjusted-score and --use-lcb-score boolean flags are aliases for --decision-score adjusted and --decision-score lcb respectively, kept for backwards compatibility. When both --decision-score and a boolean alias are specified, --decision-score takes precedence.

explain command

Print a detailed breakdown for one sample:

quietset explain scored.jsonl --sample-id a
sample_id:          a
decision:           keep
n_observations:     3
stability_score:    0.9700

  seed_robustness            0.9200  ██████████████████

Add --json to get the full StabilityReport as JSON.

Note: this example uses the default raw-score decision mode (stability_score = 0.97 → keep). With --use-adjusted-score (confidence ≈ 0.50 at n=3), adjusted_score = 0.74 falls below the keep threshold — the decision would be review unless --keep-threshold is lowered. With --use-lcb-score, label_agreement_lcb ≈ 0.44 also falls below 0.85 — review.

compare command

Compare two scored JSONL files by sample_id:

quietset compare before.jsonl after.jsonl
matched samples:  10000
mean stability:   0.7412 → 0.7801

decision transitions (before → after):
              →keep   →review    →drop
      keep↓    7210       311       42
    review↓     508      2101      301
      drop↓      19       104      404

top 5 regressions:
  sample_001  0.9100 → 0.4400  (Δ-0.4700)
  sample_382  0.8800 → 0.3900  (Δ-0.4900)

Add --json for machine-readable output.

Add --components to show per-dimension mean deltas:

quietset compare before.jsonl after.jsonl --components
matched samples:  10000
mean stability:   0.7412 → 0.7801

decision transitions (before → after):
...

component deltas (mean before → after):
  label                      0.88 → 0.90  (+0.02)
  score_consistency          0.79 → 0.86  (+0.07)
  budget_robustness          0.91 → 0.72  (-0.19)  ← regression
  seed_robustness            0.88 → 0.89  (+0.01)

--json adds a component_deltas object with signed delta values.

summary command

quietset summary scored.jsonl
samples:              1000
  keep:                621  (62.1%)
  review:              291  (29.1%)
  drop:                 88   (8.8%)
  lcb_keep_demotions:  139  (stability_score >= 0.85, label_agreement_lcb < 0.85)

stability_score:
  mean:              0.7412
  median:            0.7810
  p10 / p90:         0.4200 / 0.9600

score dispersion (mean across samples):
  mad:               0.0421
  iqr:               0.0812

top instability drivers (review + drop samples):
  label disagreement        38%
  score variance            24%
  seed sensitivity          21%
  budget sensitivity        17%

lcb_keep_demotions counts samples where stability_score >= keep_threshold (raw mode would keep them) but label_agreement_lcb < keep_threshold (LCB mode would not) — the number of samples that switching to --decision-score lcb would demote from keep. Samples already below the threshold in raw mode are excluded. Pass --keep-threshold to match the value used during scoring.

Use --json for CI integration:

quietset summary scored.jsonl --json | jq '.drop_rate < 0.1'

filter command

In addition to --min-stability, --max-disagreement, and --decision, filter supports diagnostic field filters:

Flag Keeps records where
--min-label-lcb <f> label_agreement_lcb >= f (drop low-evidence keeps)
--min-confidence <f> confidence >= f (drop low-observation-count samples)
--max-score-mad <f> score_mad <= f (drop high-dispersion samples)
--max-score-iqr <f> score_iqr <= f (drop high-spread samples)
# Keep only samples with high evidence and low score dispersion
quietset filter scored.jsonl --min-label-lcb 0.70 --min-confidence 0.60 --max-score-mad 0.05 > clean.jsonl

Records that lack the filtered field (e.g. label_agreement_lcb is absent when no labels were provided) are excluded by --min-* filters and included by --max-* filters.

reliability command (experimental)

Stability measures agreement, not correctness. Use stable-wrong-risk to quantify how many of your kept samples are consistently wrong — the most dangerous failure mode in stability-filtered datasets.

Estimate per-evaluator reliability from observation JSONL:

quietset reliability input.jsonl
{"evaluator_id": "m1", "reliability": 0.94}
{"evaluator_id": "m2", "reliability": 0.71}
{"evaluator_id": "m3", "reliability": 0.52}
{"fleiss_kappa": 0.81, "krippendorff_alpha": 0.83}

Reliability is the fraction of evaluations where the evaluator's label matches the reference label. By default, the reference is the majority label across evaluators. If gold_label is set on any observation for a sample, it is used as the reference instead — enabling ground-truth-based reliability without changing the scoring output.

The trailing line reports two dataset-level agreement statistics:

Field Meaning
fleiss_kappa Inter-rater agreement corrected for chance (nominal labels, variable raters per subject). 0 = chance, 1 = perfect, negative = worse than chance.
krippendorff_alpha Agreement coefficient using the coincidence-matrix formulation for nominal labels. More general than kappa; same scale.

Both are omitted when fewer than 2 subjects have at least 2 ratings each (undefined). Use jq 'select(.fleiss_kappa)' to extract the summary line.

When gold_label is present, each evaluator line also includes a confusion matrix (predicted → gold → count):

{"evaluator_id": "m1", "reliability": 0.94, "confusion": {"win": {"win": 120, "loss": 8}, "loss": {"win": 11, "loss": 101}}}
{"evaluator_id": "m2", "reliability": 0.71, "confusion": {"win": {"win": 98, "loss": 31}, "loss": {"win": 4, "loss": 107}}}
{"fleiss_kappa": 0.81, "krippendorff_alpha": 0.83}

audit command

Deep diagnostic report for a scored JSONL file:

quietset audit scored.jsonl
quietset audit scored.jsonl --json           # machine-readable
quietset audit scored.jsonl --top 20         # show top 20 in each list (default 10)
=== quietset audit ===
total:              1000
  keep:              621  (62.1%)

  drop:               88   (8.8%)
  lcb_keep_demotions:  139  (stability >= 0.85, lcb < 0.85)

stability_score:
  mean:            0.7412
  median:          0.7810
  p10 / p90:       0.4200 / 0.9600

top instability drivers:
  label disagreement        38%
  score variance            24%

--- borderline (0.75 <= stability <= 0.95, top 10) ---
  sample_042  0.8201  review
  sample_187  0.8490  keep

--- high_raw_low_lcb (stability >= 0.85, lcb < 0.85, top 10) ---
  sample_003  stability=0.9100  lcb=0.3423

--- budget_sensitive (top 10) ---
  sample_091  budget_sensitivity=0.8200

--json output includes borderline, high_raw_low_lcb, high_score_mad, budget_sensitive, and seed_sensitive as arrays of {sample_id, ...} objects, suitable for piping to downstream tools.

calibrate command

Find a keep_threshold that meets a precision or coverage target, using gold_label observations:

quietset calibrate input.jsonl --target-precision 0.95
quietset calibrate input.jsonl --target-precision 0.98 --decision-score lcb
quietset calibrate input.jsonl --target-precision 0.90 --target-coverage 0.50
{
  "decision_score": "lcb",
  "keep_threshold": 0.91,
  "drop_threshold": 0.40,
  "achieved_precision": 0.982,
  "precision_ci_low": 0.943,
  "precision_ci_high": 0.997,
  "coverage": 0.61,
  "n_keep": 610,
  "n_total": 1000,
  "validated_on_heldout": false,
  "note": "achieved_precision and its confidence interval were selected and measured on the same gold-labeled data; the threshold search makes this optimistic. Pass --heldout <path> for an independent estimate."
}

calibrate grid-searches keep_threshold from 0.99 down to 0.50 (step 0.01) and returns the loosest threshold that meets the target. Requires gold_label on at least one observation per sample. Returns an error if no threshold meets the target (try a lower --target-precision).

precision_ci_low/precision_ci_high is a Wilson score interval around achieved_precision at --confidence-level (the same knob used for the lcb decision score) — it widens automatically when few gold labels back the estimate, so don't treat achieved_precision alone as exact when n_keep is small. The interval covers sampling noise at the chosen threshold only, not the fact that the threshold itself was picked to hit the target on these same gold labels — it is still optimistic. Treat it as a lower bar, not the full uncertainty; a held-out gold set is the more conservative check. note makes this caveat machine-readable: it's always present when --heldout was not used (as above), and present when --heldout was used but the training-set precision at the selected threshold exceeded the held-out precision by more than 0.05 (a likely overfit); null when --heldout was used and the gap was small enough to be ordinary sampling noise.

Use --heldout <path> to get that more conservative check: keep_threshold is still selected by grid search on the primary input, but achieved_precision/precision_ci_low/ precision_ci_high/coverage/n_keep/n_total are instead measured on the held-out file's own gold_labels at that fixed threshold. For raw/adjusted/lcb/latent-truth this fully removes the circularity — the threshold-selection circularity is gone, and latent-truth's EM never consumes gold labels at all, so grading its inferred labels against held-out gold is a genuine independent check even on the same samples. For gold-weighted, one layer of circularity remains: the per-evaluator reliability weights are fit from the held-out file's own gold_labels and then graded against those same labels, so treat its held-out precision as better than the in-sample number but not fully independent. Not stdin-capable (-); the primary input already claims stdin. Requires gold_label on the held-out file, or the command errors. The reported precision can legitimately land below --target-precision when the primary-input-selected threshold overfits — that's the correct, honest signal, not a bug. validated_on_heldout in the output discloses whether --heldout was used, so a saved result still says what it measured. train_precision exposes the in-sample precision at the same threshold alongside achieved_precision (which becomes the held-out precision once --heldout is used) — null unless --heldout was given, since otherwise it would just repeat achieved_precision:

quietset calibrate input.jsonl --target-precision 0.95 --heldout heldout_gold.jsonl
{
  "decision_score": "raw",
  "keep_threshold": 0.99,
  "drop_threshold": 0.40,
  "achieved_precision": 0.71,
  "precision_ci_low": 0.44,
  "precision_ci_high": 0.89,
  "coverage": 1.0,
  "n_keep": 24,
  "n_total": 24,
  "train_precision": 0.97,
  "validated_on_heldout": true,
  "note": "in-sample precision at this threshold was 0.970, held-out precision is 0.710 (gap 0.260) — the training-selected threshold likely overfit the training gold labels"
}

Use --output-format csv for a single header row + one data row instead of a JSON object:

quietset calibrate input.jsonl --target-precision 0.95 --output-format csv
decision_score,keep_threshold,drop_threshold,achieved_precision,precision_ci_low,precision_ci_high,coverage,n_keep,n_total,train_precision,validated_on_heldout,note
lcb,0.910000,0.400000,0.982000,0.943000,0.997000,0.610000,610,1000,,false,"achieved_precision and its confidence interval were selected and measured on the same gold-labeled data; the threshold search makes this optimistic. Pass --heldout <path> for an independent estimate."

Use --fail-below-target to make calibrate a CI gate: it exits non-zero (after still printing the result) if achieved_precision falls short of --target-precision. Without --heldout this is effectively a no-op — the grid search already guarantees achieved_precision >= --target-precision on the primary input, or fails outright with an error. With --heldout, achieved_precision is the held-out measurement, which can legitimately fall short — this flag turns that honest signal into something a CI pipeline can act on:

quietset calibrate train.jsonl --heldout heldout.jsonl --target-precision 0.98 --fail-below-target
echo "exit code: $?"

Note: calibrate cannot separate stable-correct from stable-wrong samples — if a sample consistently gets the wrong label, its stability_score is indistinguishable from a correct sample. Use gold_label-based reliability diagnostics to identify systematically wrong evaluators.

select command

Extract samples by diagnostic class, outputting the original scored JSONL lines (pass-through, pipeable to other commands):

quietset select scored.jsonl --class borderline --top 100
quietset select scored.jsonl --class high-raw-low-lcb > uncertain_keeps.jsonl
quietset select scored.jsonl --class budget-sensitive --top 20 | quietset explain - --sample-id x
Class Selects
borderline keep_threshold ± 0.10 stability band (uncertainty zone)
high-disagreement sorted by disagreement_score descending
budget-sensitive sorted by budget_sensitivity descending
seed-sensitive sorted by seed_sensitivity descending
high-raw-low-lcb stability_score >= keep_threshold but label_agreement_lcb < keep_threshold
high-score-mad sorted by score_mad descending

Use --top N to limit output. Use --keep-threshold to adjust the band for borderline and high-raw-low-lcb (default 0.85).

recommend command

Emit a re-evaluation suggestion for each sample that has a detectable issue, in priority order:

quietset recommend scored.jsonl
quietset recommend scored.jsonl --unstable-only   # skip clean keeps
{"sample_id": "x42", "reason": "high_raw_low_lcb", "recommended_action": "add_observations", "stability_score": 0.91, "label_agreement_lcb": 0.34, "n_observations": 2}
{"sample_id": "y17", "reason": "high_seed_sensitivity", "recommended_action": "add_seeds", "seed_sensitivity": 0.71}
Reason Action
high_raw_low_lcb LCB below threshold despite high raw stability → add_observations
low_evaluator_agreement evaluator_agreement < 0.7 → add_evaluators
high_seed_sensitivity seed_sensitivity > 0.3 → add_seeds
high_budget_sensitivity budget_sensitivity > 0.3 → increase_budget
low_model_agreement model_agreement < 0.7 → add_models
low_score_consistency score_consistency < 0.7 → reduce_score_variance

Each sample emits at most one recommendation (highest priority rule wins).

stable-wrong-risk command

Scores observation JSONL internally and reports kept samples whose majority_label differs from gold_label:

quietset stable-wrong-risk input.jsonl
quietset stable-wrong-risk input.jsonl --keep-threshold 0.90
{
  "n_total": 1000,
  "n_keep": 621,
  "n_stable_wrong": 12,
  "stable_wrong_rate_among_keep": 0.019,
  "samples": [
    {"sample_id": "x42", "stability_score": 0.96, "majority_label": "loss", "gold_label": "win"}
  ]
}

Requires gold_label on observations. Sorted by stability_score descending — the most confidently-kept wrong samples appear first. Use --top N to limit the sample list.

Use --breakdown to also report stable_wrong_rate per evaluator_id/model_id/budget value among Keep-decision samples — spotting a specific evaluator/model/budget that shows up disproportionately often in stably-wrong-but-kept samples:

quietset stable-wrong-risk input.jsonl --breakdown
{
  "n_total": 1000,
  "n_keep": 621,
  "n_stable_wrong": 12,
  "stable_wrong_rate_among_keep": 0.019,
  "samples": [ ... ],
  "by_evaluator": [
    {"evaluator_id": "m1", "n_keep": 340, "n_stable_wrong": 9, "stable_wrong_rate": 0.026},
    {"evaluator_id": "m2", "n_keep": 281, "n_stable_wrong": 3, "stable_wrong_rate": 0.011}
  ],
  "by_model": [ ... ],
  "by_budget": [ ... ]
}

Each breakdown is sample-level, like the top-level rate: by_evaluator[i].n_keep counts Keep samples that touch that specific evaluator_id, not observations. A sample can touch multiple evaluators/models/budgets at once, so rows within a breakdown do not sum to the top-level n_keep — that's intentional, not a partition; it answers "which evaluators/models/budgets show up in wrong-but-confident samples," not "whose fault is it." Off by default, since it clones the input and does an extra grouping pass.

compare --policy-after

After the standard comparison output, show how decisions in the after file would change under a hypothetical decision-score policy:

quietset compare before.jsonl after.jsonl --policy-after lcb
quietset compare before.jsonl after.jsonl --policy-after adjusted --policy-keep-threshold 0.80
policy comparison: current → lcb (keep_threshold=0.85):
              →keep   →review    →drop
    keep↓         0       850        0
  review↓         0      2291      300
    drop↓         0         0      200
  demoted by policy: 850  promoted: 0

Note: --policy-after lcb uses label_agreement_lcb as a proxy for the LCB policy score. Other components are not recomputed, so results are approximate. Use for directional signal ("how many keeps would be demoted"), not precise prediction.

policy command

Sweeps keep_threshold from 0.99 down to 0.50 and reports the precision/coverage/stable-wrong-rate trade-off at each step, so you can pick a threshold before running score:

quietset policy input.jsonl
quietset policy input.jsonl --target-precision 0.95
quietset policy input.jsonl --decision-score lcb --json
threshold  n_keep  coverage
0.99            1     0.500
0.98            1     0.500
0.97            1     0.500

With gold_label present on observations, the table also gains precision and stable_wrong_rate columns. --target-precision/--target-coverage mark the loosest threshold meeting that target with . --output-format json emits one JSONL object per threshold row instead of the formatted table (--json still works as an alias; passing both warns and --output-format wins). --output-format csv emits one row per swept threshold with fixed columns threshold,n_keep,coverage,precision,stable_wrong_rate,bestprecision/ stable_wrong_rate are empty when no gold_label is present, and best is true only on the row matching --target-precision/--target-coverage:

quietset policy input.jsonl --target-precision 0.95 --output-format csv
threshold,n_keep,coverage,precision,stable_wrong_rate,best
0.99,1,0.500000,1.000000,0.000000,
0.98,1,0.500000,1.000000,0.000000,true

active-review command

Ranks scored JSONL samples by re-evaluation urgency — a weighted combination of low label_agreement_lcb, high label_entropy, high score_mad, and high budget/seed sensitivity:

quietset score input.jsonl | quietset active-review -
quietset active-review scored.jsonl --unstable-only --top 20
{"budget_sensitivity":0.625,"cost":1.0,"expected_coverage_gain":1.0,"expected_risk_reduction":0.0,"label_agreement_flip_ratio":0.818,"label_agreement_lcb":0.301,"label_entropy":0.811,"primary_reason":"high_entropy","sample_id":"b","seed_sensitivity":0.075,"suggested_action":"add_evaluator","urgency_score":0.502,"utility":0.818}

--unstable-only skips samples already decided keep with no instability signals. Per-signal --weight-* flags (--weight-lcb, --weight-entropy, --weight-score-mad, --weight-budget-sensitivity, --weight-seed-sensitivity) let you emphasize the signal most relevant to your review budget. suggested_action is one of request_gold_label, add_evaluator, add_model, increase_budget, add_seed (renamed from the earlier add_observations/diversify_evaluators/reduce_score_variance/add_budget/add_seeds — a breaking change, see CHANGELOG).

Five additional fields turn the urgency heuristic into an expected-value ranking:

  • label_agreement_flip_ratio — a distance-to-threshold ratio in [0.0, 1.0]: 1.0 exactly at --keep-threshold/--drop-threshold, shrinking toward 0.0 further away, relative to label_agreement's own Wilson-CI margin of error. Not a probability — only label_agreement's sampling uncertainty is modeled; stability_score's other components (score dispersion, budget/seed sensitivity, model/evaluator agreement) have no uncertainty model in this codebase, so this ratio is a loose proxy whenever those other components actually drive stability_score. None when the sample has no labels.
  • expected_coverage_gain1 / n_total if the sample's decision (read verbatim from the input, not re-derived) is not keep, else 0.0: the exact coverage change if this sample's decision flipped to keep.
  • expected_risk_reduction1 / n_keep if the sample is a keep whose label_agreement_lcb falls below --keep-threshold (the same "at-risk keep" condition stable-wrong-risk's lcb_keep_demotions counts), else 0.0.
  • cost — the cost of suggested_action, from --cost-seed/--cost-budget/ --cost-evaluator/--cost-gold-label (all default 1.0; --cost-evaluator also backs add_model).
  • utilitylabel_agreement_flip_ratio * (expected_coverage_gain + expected_risk_reduction) / cost. A ranking score, not a literal expected value — ordering by it is sound (closer to threshold, higher payoff, cheaper actions rank higher), but don't read the absolute number as a calibrated expectation.

--keep-threshold/--drop-threshold (defaults 0.85/0.40, matching score's own defaults) feed only label_agreement_flip_ratio and the at-risk-keep gate — they do not re-derive decision. --rank-by urgency (default) sorts by urgency_score; --rank-by utility sorts by utility instead, surfacing samples where additional review effort pays off most rather than samples that merely look unstable.

Use --plan <path> to write a budget-constrained evaluation plan — a JSONL file, always sorted by utility descending regardless of --rank-by, in addition to the normal stdout output. --budget <f64> caps the total cost of entries it includes: entries are taken greedily by utility, skipping (not stopping at) any that don't fit so a cheaper lower-utility entry later in the list can still be included. Without --budget, --plan writes every entry (still utility-sorted):

quietset active-review scored.jsonl --plan next_eval_plan.jsonl --budget 20.0

This is a standard greedy value-density approximation for a knapsack-style budget allocation problem — not guaranteed globally optimal, but sound for "what should the next batch of review effort go toward."

Rust API

use quietset::{Observation, ScoreConfig, score_all};

let obs = vec![
    Observation { sample_id: "a".into(), label: Some("win".into()), score: Some(0.9), ..Default::default() },
    Observation { sample_id: "a".into(), label: Some("win".into()), score: Some(0.88), ..Default::default() },

Compared to adjacent tools

Tool What it does How quietset differs
Cleanlab Python library that detects label errors using trained classifiers and confident learning. quietset needs no model training and makes no task-specific assumptions. It filters by cross-run stability rather than estimated label quality.
Label Studio Web-based annotation platform for labelling images, text, audio, and time series. quietset is a CLI/library primitive, not an annotation UI. It measures stability of labels already produced by other tools.
pandas / polars General-purpose data manipulation libraries. quietset provides a purpose-built stability schema — decisions, per-dimension sub-scores, confidence, instability diagnostics — that would otherwise require substantial custom code.
Great Expectations / Soda Data quality frameworks that validate data against rules (nulls, ranges, schema). Those tools check whether data conforms to a schema. quietset checks whether labels or scores are consistent across repeated evaluations.
scipy.stats / sklearn metrics Statistical functions such as Cohen's kappa and Fleiss' kappa. quietset wraps similar ideas into a composable pipeline primitive with JSONL I/O, per-sample reports, confidence adjustment, and configurable thresholds.
LLM evaluation frameworks (RAGAS, DeepEval) Frameworks that score LLM outputs against reference answers using model-based judges. quietset is judge-agnostic. It takes whatever scores or labels your judges produce and measures agreement across runs, budgets, models, or seeds.

Python bindings

crates/quietset-py provides Python bindings via pyo3 + maturin. Status: alpha / experimental — the core scoring API is wrapped but the interface may change. It is excluded from the Cargo workspace and from CI (cargo build/test --workspace never touches it); build and test it manually from within crates/quietset-py.

cd crates/quietset-py && maturin develop
import quietset
result = quietset.score_jsonl(
    '{"sample_id":"a","label":"win","score":0.9}\n'
    '{"sample_id":"a","label":"win","score":0.8}\n'
)
print(result)

The bindings currently expose a single function, score_jsonl, which scores a JSONL string with default settings and returns a JSONL string of results. The CLI is the stable interface with the full set of commands and options; use Python bindings for embedding basic scoring in existing Python pipelines where spawning a subprocess is impractical.
