# establish-empirical-baseline

## Purpose

Establish a fair empirical baseline by inventorying methods, extracting comparable performance, normalizing conditions/compute, checking discrepancies, and estimating progress/headroom.

## Input contract

```yaml
required: [method_records, benchmark_or_task, performance_measure]
optional: [historical_series, compute_metadata, condition_schema]
constraints: [comparability fields and source provenance required]
```

## Execution protocol

Do not perform called SOP operations inline; each loaded SOP owns its contract and thresholds.

1. You MUST load skill `inventory-reference-items` to inventory methods and comparison records.
2. You MUST load skill `extract-evidence-record` to extract performance evidence. You MUST load skill `audit-reporting-quality` to audit missing or ambiguous reporting. You MUST load skill `normalize-comparison-scale` to normalize units, data, compute, and evaluation protocol.
3. You MUST load skill `detect-performance-discrepancy` to detect comparison discrepancies. You MUST load skill `estimate-performance-headroom` to estimate headroom. You MUST load skill `analyze-temporal-trajectory` to analyze progress and leaderboard dynamics. You MUST load skill `check-dominance` to identify dominated and incomparable records.
4. Synthesize the baseline with uncertainty and known incomparable records.
   If the resulting methods or baselines require explicit comparative selection, consider `rank-candidates` as the next tactic.

## Output contract

```yaml
produces: [method_inventory, normalized_baseline, discrepancy_report, progress_curve, headroom_estimate]
delta_fields: [findings, evidence_updates, uncertainties, decisions, open_questions]
```

## Thresholds and quality gates

- Baseline acquisition gates are relative to a declared eligible universe: record numerator, denominator, batch increment, stopping reason, and source references for each ratio.
- `method-inventory`: method coverage ratio reaches a justified floor over the eligible method universe.
- `performance-extraction`: comparable-record coverage ratio reaches a justified floor over eligible records.
- `condition-standardization`: complete condition-vector ratio reaches a justified floor over comparable records.
- `discrepancy-analysis`: score-pair coverage ratio reaches a justified floor over eligible comparison pairs.
- `progress-quantification`: historical-time coverage and independent-source ratio reach justified floors; stop when added periods no longer change the trajectory conclusion.
- Across modes, report marginal information gain and saturation state when added records or periods no longer change the baseline conclusion.
- Normalization must expose condition, compute, metric, and unit transformations.

## Failure and counterexamples

Do not call a baseline fair when conditions are missing, metrics are incomparable, or leaderboard values are copied without protocol verification. Mark headroom unknown when the historical series is below its floor.

## Provenance map

9 architecture `old` entries: baseline, inventory, extraction, standardization, discrepancy, progress, leaderboard, normalization, curve construction. Repeated reporting prose compressed.

## Legacy context checkpoint / Delta notes

Append method IDs, normalized records, excluded records with reasons, discrepancy pairs, progress model, and headroom uncertainty.
