Use for\n  trials, model comparisons, and reproducible research history.\nlicense: MIT\nmetadata:\n  version: \"0.12.0\"\n---\n\n# Experiment Log\n\n## When to Use This Skill\n\nUse when:\n\n- starting a modeling experiment that should be comparable later;\n- the user asks “what did we try?” or needs a decision history;\n- promoting/rejecting candidates under a locked validation design;\n- recording failures, deviations, and why a model was or was not shipped.\n\nDo **not** use this skill as a substitute for:\n\n- locking metrics and folds → `validation-design`;\n- writing the public-facing results narrative → `results-reporting`;\n- the durable model contract → `model-card`.\n\n| Need | Go instead |\n|---|---|\n| Validation charter | `validation-design` |\n| Results writeup | `results-reporting` |\n| Model contract | `model-card` |\n\n## Outcome\n\nCreate one immutable record per executed experiment so another analyst can\nreconstruct what was tried, compare it with its declared baseline, audit its\nvalidity, and understand why it was kept, discarded, or queued for follow-up.\nFailed runs are evidence and belong in the history.\n\nAn experiment log is trial history. A validation charter defines evaluation; a\nmodel card freezes a promoted model contract; a results report explains an\nevaluation to readers.\n\nRead [the log schema](references/log_schema.md) while creating or auditing a\nrecord and [the decision rules](references/decision_rules.md) before assigning\nthe final decision.\n\n## Create before execution\n\nRecord before fitting:\n\n- unique ID, UTC timestamp, operator, falsifiable hypothesis, expected direction;\n- sport, competition, row grain, target, population, and decision time T;\n- immutable data snapshot/query and its source/retrieval metadata;\n- feature-set reference with availability and transformation rules;\n- baseline/candidate configuration, validation charter, and locked primary metric;\n- code version, environment/lock reference, random seeds, and exact command;\n- predeclared success, integrity, calibration, stability, and complexity limits.\n\nDo not rewrite these fields after observing results. Corrections and deviations\nare appended with timestamp, author, reason, and effect on validity.\n\n## Schema\n\n```text\nexperiment_id: YYYYMMDD-<slug>-<nn>\ncreated_at_utc:\noperator:\nhypothesis / expected direction:\nsport / competition / grain / target / eligible population:\nprediction_timestamp_rule:\ndata_sources / immutable_snapshot / data_window:\nfeature_set_ref / baseline_refs:\nvalidation_charter_ref / primary_metric / success_rule:\nmodel_family / config_ref / code_version / environment_ref:\nrandom_seeds / commands:\nstatus: planned | running | completed | failed | invalidated\nfold_metrics / metrics_primary / metrics_secondary:\ncalibration / slice / stability results:\nleakage_audit_status / failures / deviations:\nresults_summary:\ndecision: keep | discard | follow-up | invalid\ndecision_reason / next_actions:\nartifacts / checksums / notes:\n```\n\n## Workflow\n\n1. Search existing logs, assign a new ID, and create the record before the run.\n2. Freeze the falsifiable hypothesis, primary metric, baselines, and success rule.\n3. Link immutable data, feature, validation, config, code, and environment artifacts.\n4. Record exact noninteractive commands or notebook cell/version identifiers.\n5. Execute baseline and candidate on identical eligible rows and folds.\n6. Append fold-level metrics, runtime, warnings, and output artifact checksums.\n7. Record calibration, leakage, slice, and failure diagnostics where applicable.\n8. Mark deviations and invalid runs; never delete or convert them into successes.\n9. Decide from the predeclared rule, then record one concrete next action if needed.\n10. Promote to a model card only after `keep` and all integrity gates pass.\n\n## Comparison discipline\n\nCandidate comparisons are valid only when target, T, population, data snapshot,\nrows, folds, metrics, and baseline definitions match. If they differ, log the\ndifference and do not attribute the metric change solely to the model.\n\nStore per-fold results rather than averages only:\n\n```text\nfold | train_period | test_period | n | baseline_primary | candidate_primary |\ngap | secondary_metrics | calibration | warnings\n```\n\nInclude uncertainty or dispersion appropriate to the design. Never promote a\ncandidate because one favorable fold offsets repeated failures hidden by a mean.\n\n## Decision rules\n\n| Decision | Use when |\n|---|---|\n| `keep` | predeclared success met on locked evaluation and integrity gates pass |\n| `discard` | honestly fails baseline/rule or adds unsupported complexity |\n| `follow-up` | signal is plausible but one named uncertainty needs one concrete test |\n| `invalid` | leakage, execution failure, charter violation, or incomparable rows prevents inference |\n\nPost-hoc metrics must be labeled `post-hoc` and cannot silently drive the\nprimary decision. A changed metric, population, or hypothesis requires a new ID.\n\n## Failure and deviation handling\n\nRecord nonzero exits, exceptions, timeouts, warnings, empty folds, missing\nartifacts, convergence failures, seed instability, and manual intervention.\nInclude the last valid stage and whether partial outputs are trustworthy.\n\nWhen leakage or a validation violation is found later, append an invalidation\nentry to every affected experiment and downstream artifact. Do not overwrite\nthe original record or reuse its metrics after repair; the repaired run gets a\nnew experiment ID linked to the invalidated one.\n\n## Anti-patterns\n\n| Anti-pattern | Consequence | Correct behavior |\n|---|---|---|\n| winner-only logging | selection bias disappears from history | log all planned/executed runs |\n| hypothesis written after score | retrospective story | freeze before fitting |\n| reused experiment ID | configurations become ambiguous | new ID for every material change |\n| mutable data path only | run cannot be reconstructed | snapshot/query + checksum/version |\n| screenshots without raw metrics | evidence cannot be audited | link structured fold metrics |\n| changed rows/folds undisclosed | comparison is confounded | common sample or explicit caveat |\n| final metric replaced post-hoc | goalposts move | label exploratory; new experiment |\n| failed run deleted | troubleshooting and selection history lost | status `failed` with evidence |\n\n## Standalone helper\n\n```bash\npython /path/to/experiment-log/scripts/new_experiment.py \\\n  --slug home-form-logit --sport nfl\npython /path/to/experiment-log/scripts/new_experiment.py \\\n  --slug elo-sensitivity --out-dir data/experiments\n```\n\nThe helper creates a timestamped, user-owned Markdown artifact and validates\nthe slug. Creation is exclusive: concurrent invocations retry the sequence and\nnever overwrite or reuse an existing ID. The stub contains every field in the\nrequired schema, but it is only a `planned` record; complete the pre-run fields\nbefore execution and append results/deviations without rewriting the frozen\ncontract.\n\n## Worked example\n\n```text\nexperiment_id: 20260824-home-form-logit-01\nhypothesis: Shifted 5-game form improves test log-loss over constant train rate.\nsport / grain / target: nfl / team-game / won\nprediction_timestamp_rule: scheduled kickoff\nimmutable_snapshot: snapshots/nfl_team_game_2019_2025.parquet (sha256: ...)\nfeature_set_ref: feature-cards/team-form-v3.md\nvalidation_charter_ref: charters/season-wf-v2.md\nprimary_metric: log-loss\nsuccess_rule: beat baseline on mean and majority of outer folds; audit CLEAN\ncommands: [exact invocation]\nstatus: completed\nfold_metrics: artifacts/20260824-home-form-logit-01-folds.json\nleakage_audit_status: CLEAN\ndecision: keep | discard | follow-up | invalid\ndecision_reason: fill after evaluation\n```\n\n## Review checklist and integrity rules\n\n- ID existed before results; hypothesis is falsifiable.\n- Data, code, config, feature, charter, environment, seeds, and commands resolve.\n- Baseline/candidate share rows, folds, and metrics or differences are disclosed.\n- Fold-level results and failed checks are present.\n- Leakage status and decision follow the predeclared rule.\n- Referenced artifacts are immutable and checksummed where practical.\n\nNever omit failed runs, alter the primary metric silently, overwrite referenced\nartifacts, or promote without a baseline and timing audit. Use `log_schema.md`\nfor required field semantics and `decision_rules.md` for promotion logic.\n","tagline":"Record sports-modeling experiments with the hypothesis, data cut, validation charter, metrics, leakage status, decision, commands, and artifacts.
