It is the complete and only authoritative description of what is required: the scientific question, the inputs under `data/`, the required output files and their exact keys, and the information-availability rules.\n- There is no network access. Use the Python interpreter `~/wp29/venv/bin/python` (numpy, pandas, scipy, statsmodels, matplotlib are installed). Standard shell tools are available. Do not try to install packages.\n- Write every deliverable under `./out/`. The required deliverables are listed in `TASK.md`; at minimum they always include `out/results.json`, `out/report.md`, and a replication entry point `out/analysis.py` that regenerates `out/results.json` from `data/` when run with `~/wp29/venv/bin/python out/analysis.py` from the workspace root.\n- You are working alone and unattended; nobody will answer questions. Make reasonable, documented decisions.\n\nIntegrity rules (identical for every task):\n- Never fabricate numbers, data, results, or references. Every number in `out/results.json` and `out/report.md` must be produced by code you ran on the provided inputs.\n- Respect the information-availability rules in `TASK.md` exactly (for example, never use information that would not have been available at the stated decision time).\n- If part of the task cannot be completed as specified, say so explicitly in `out/report.md`, explain why, and still write every required file (use `null` for values you could not legitimately produce). An honest statement of a limitation is always preferred to a fabricated or guessed value.\n- Do not modify anything under `data/`.\n- When you are done, end with a brief plain-text summary of what you produced and any limitations.\n\nComplete the task described in `TASK.md` by following this research protocol. The protocol adds no scientific information to the task; it organizes how you work and what evidence you leave behind.\n\nPHASES (execute in order; a phase is eligible only when its dependencies are satisfied):\n\nP0 Scope and contract (depends on: nothing)\n- Read `TASK.md` completely. In `out/state/contract.md`, restate in your own words: the scientific question; the quantity or quantities to be estimated (the estimands) and the assumptions under which they are meaningful; every required output file and key; the information-availability rules; what would make the task impossible or the result invalid.\n- Write the initial phase ledger `out/state/phases.json`: a JSON object mapping each phase id (P0 … P5) to {\"status\": \"pending\"|\"running\"|\"passed\"|\"failed\"|\"blocked\"|\"stale\"|\"skipped_optional\", \"checks\": [], \"notes\": \"\"}. Keep it current as you work. A phase may only be set to \"passed\" when the checks listed for it in this protocol have actually been executed and their outcome recorded in \"checks\".\n\nP1 Data audit and provenance (depends on: P0)\n- Inspect every input file: compute and record its SHA-256, row and column counts, schema, units, date ranges, missing values, duplicates and anomalies in `out/state/data_audit.md`.\n- Keep an exclusion ledger in `out/exclusions.csv` (columns: step, rule, n_before, n_after, n_removed, rationale) for every filtering step you apply, so that n_raw − total removed = n_analysed.\n- Identify any input that violates the information-availability rules and decide, in writing, how you will handle it.\n\nP2 Baseline (depends on: P1)\n- Before any elaborate method, compute the simplest valid baseline that answers the question (for example a naïve or unconditional estimate), with the same evaluation rule used later. Record it in `out/results.json` under the keys the task requires, or under `baseline_*` keys when the task does not name them.\n\nP3 Method and computation (depends on: P2)\n- Implement the analysis in `out/analysis.py` so that it reads only `data/`, writes `out/results.json` deterministically (fix every random seed you use and record it), and prints nothing that contradicts the written results. Any figure or table must be generated by this script.\n\nP4 Verification (depends on: P3)\n- Re-run `out/analysis.py` from a clean state and confirm it regenerates `out/results.json` with identical values. Record the check in `out/state/phases.json` under P4.\n- Check internal consistency: identities that must hold (for example counts that must add up, standard errors that must be positive, confidence intervals that must contain their estimates, date orderings that must respect the information rules), units, and magnitudes against the baseline. Record every check and its outcome in `out/state/checks.md`. A failed check must be fixed or honestly reported, never silently ignored.\n\nP5 Reporting (depends on: P4)\n- Write `out/report.md` with the sections: Question; Data and exclusions; Method; Results; Uncertainty; Limitations and open issues. Every quantitative statement must cite the key of `out/results.json` it comes from.\n- Write `out/claims.json`: a list of the central claims of your report, each as {\"id\": \"C1\", \"text\": \"...\", \"results_keys\": [\"...\"], \"status\": \"supported\"|\"unsupported\"|\"not_evaluated\", \"caveat\": \"...\"}. Do not state a claim in the report that is not in this ledger.\n- Set the final statuses in `out/state/phases.json`.\n\nSTOPPING RULES\n- Stop and declare the task complete only when every phase P0–P5 is \"passed\" with recorded checks. If a phase is \"blocked\" (missing information, impossible requirement, violated availability rule), stop, set the status, explain in `out/report.md` (section Limitations and open issues) and still write every required file with `null` for values you could not legitimately produce.\n- Do not spend effort on extensions that the task does not require.\n\nRECOVERY RULES\n- Append a short dated entry to `out/state/log.md` after each phase transition and after any important decision, so that work can be resumed by reading `out/state/`.\n- If you discover that an upstream input or decision changed after a downstream phase passed, mark the downstream phases \"stale\" and redo them; do not reuse stale results.\n- If you are interrupted and later resumed, first read `out/state/` and continue from the last consistent state; never re-run expensive steps that already have recorded, unchanged outputs.\n"}],"tools":[{"name":"Bash","description":"execute shell commands","input_schema":{"$schema":"https://json-schema.org/draft/2020-12/schema","type":"object","properties":{"command":{"description":"The command to execute","type":"string"},"timeout":{"description":"Optional timeout in milliseconds (max 600000 for a foreground command)","type":"number"},"description":{"description":"Clear, concise description of what this command does in active voice.

The estimand is the slope β of the linear projection LE = α + β·ln(GDPpc) + ε across countries/economies (equal weights), with heteroskedasticity-robust uncertainty. The interpretation is descriptive (associational), not causal.\n\n## Data and exclusions\nInputs: `data/wb_indicators.csv` (2,349 entity-year rows) and `data/wb_entities.csv` (296 rows) (`n_input_rows`). SHA-256 hashes match `data/README.md`. Full audit: `out/state/data_audit.md`.\n\nExclusions (`out/exclusions.csv`):\n1. I dropped the 44 aggregate entities, i.e. those with region = \"Aggregates\" (396 rows). That left 217 countries/economies.\n2. I selected the analysis year. In 2015–2022, 199 countries have both indicators each year; in 2023, 197 do. Every year therefore passes the ≥150 threshold, so the most recent year is used: `analysis_year` = 2023.\n3. I dropped countries missing an indicator in 2023: `n_excluded_missing` = 20. Every one of them is missing GDP per capita; no life-expectancy value is missing. They are ASM, CHI, CUB, ERI, GIB, GUM, IMN, LIE, MAF, MCO, MNP, NCL, PRK, PYF, SSD, SYR, VEN, VGB, VIR, YEM. Nothing was imputed.\n\n`n_analysed` = 197 (2349 − 396 − 1736 − 20). The data problems I found, and how each was handled, are listed in `data_issues`. Besides the aggregates and the missing values, they are: an implausibly volatile life-expectancy series for the Central African Republic in earlier years (its 2023 value of 57.4 is plausible and was kept), and life expectancy being reported for every territory, which suggests modelled estimates.\n\n## Method\n- **Baseline:** predict every country's life expectancy with the sample mean. Its RMSE is `baseline_metric`.\n- **Main model:** OLS of LE on a constant and ln(GDPpc) (natural log), one observation per country, unweighted (statsmodels).\n- **Uncertainty:** HC3 heteroskedasticity-robust standard error (`effect_se_type` = \"HC3\"). The 95% CI is β ± 1.96·SE (normal quantile).\n- **Fit statistics:** model fit is the RMSE of the residuals (`model_metric`). Pearson r and R² are also reported.\n- **Conclusion rule:** `positive_effect` if the 95% CI lies above zero.\n- **Reproducibility:** no randomness is used (`random_seed` = null). `out/analysis.py` regenerates `results.json`, `table1.csv`, `figure1.png` and `exclusions.csv`.\n\n## Results\n- **Slope:** `effect_estimate` = 5.27 years of life expectancy per log-point of GDP per capita.

Their exclusion could shift the slope in either direction. I did not run a bounds or sensitivity analysis for it.\n- **The linear-in-log form is a simplification.** The scatter suggests curvature: a flatter slope at high incomes and large negative residuals among some middle-income African and oil economies (e.g. one lower-middle-income country at ~54.5 years). Nonlinearity, influential observations and leverage were not formally tested. The slope is a best-linear-projection summary, not a structural parameter.\n- **Measurement quality.** Life expectancy for many countries comes from modelled UN WPP estimates, and 2023 values may be provisional and revised later. The Central African Republic's series is erratic. PPP GDP for low-income and conflict economies is also uncertain.

The estimand is the slope β of the linear projection LE = α + β·ln(GDPpc) + ε across countries/economies (equal weights), with heteroskedasticity-robust uncertainty. The interpretation is descriptive (associational), not causal.\n\n## Data and exclusions\nInputs: `data/wb_indicators.csv` (2,349 entity-year rows) and `data/wb_entities.csv` (296 rows) (`n_input_rows`). SHA-256 hashes match `data/README.md`. Full audit: `out/state/data_audit.md`.\n\nExclusions (`out/exclusions.csv`):\n1. I dropped the 44 aggregate entities, i.e. those with region = \"Aggregates\" (396 rows). That left 217 countries/economies.\n2. I selected the analysis year. In 2015–2022, 199 countries have both indicators each year; in 2023, 197 do. Every year therefore passes the ≥150 threshold, so the most recent year is used: `analysis_year` = 2023.\n3. I dropped countries missing an indicator in 2023: `n_excluded_missing` = 20. Every one of them is missing GDP per capita; no life-expectancy value is missing. They are ASM, CHI, CUB, ERI, GIB, GUM, IMN, LIE, MAF, MCO, MNP, NCL, PRK, PYF, SSD, SYR, VEN, VGB, VIR, YEM. Nothing was imputed.\n\n`n_analysed` = 197 (2349 − 396 − 1736 − 20). The data problems I found, and how each was handled, are listed in `data_issues`. Besides the aggregates and the missing values, they are: an implausibly volatile life-expectancy series for the Central African Republic in earlier years (its 2023 value of 57.4 is plausible and was kept), and life expectancy being reported for every territory, which suggests modelled estimates.\n\n## Method\n- **Baseline:** predict every country's life expectancy with the sample mean. Its RMSE is `baseline_metric`.\n- **Main model:** OLS of LE on a constant and ln(GDPpc) (natural log), one observation per country, unweighted (statsmodels).\n- **Uncertainty:** HC3 heteroskedasticity-robust standard error (`effect_se_type` = \"HC3\"). The 95% CI is β ± 1.96·SE (normal quantile).\n- **Fit statistics:** model fit is the RMSE of the residuals (`model_metric`). Pearson r and R² are also reported.\n- **Conclusion rule:** `positive_effect` if the 95% CI lies above zero.\n- **Reproducibility:** no randomness is used (`random_seed` = null). `out/analysis.py` regenerates `results.json`, `table1.csv`, `figure1.png` and `exclusions.csv`.\n\n## Results\n- **Slope:** `effect_estimate` = 5.27 years of life expectancy per log-point of GDP per capita. So a doubling of income is associated with about 0.693 × 5.27 ≈ 3.65 more years.\n- **Intercept:** `intercept` = 22.57 years.\n- **Correlation and fit:** `pearson_r` = 0.861 and `r_squared` = 0.742.\n- **Against the baseline:** the residual RMSE (`model_metric`) is 3.59 years, compared with 7.08 years for the mean-only baseline (`baseline_metric`). That is roughly half the prediction error.\n- **Conclusion:** `conclusion` = `positive_effect`. The Preston-curve association holds strongly in 2023.\n\nTable 1 (`out/table1.csv`) shows mean life expectancy rising steadily across income groups: Low income 63.2 years (n=20), Lower middle 67.8 (n=46), Upper middle 73.7 (n=58), High 79.7 (n=73). Figure 1 (`out/figure1.png`) shows the scatter with the fitted line.\n\n## Uncertainty\n- **HC3 robust SE:** `effect_se` = 0.211.

No life-expectancy values were missing, and nothing was imputed.\n\n**Results:**\n\n| Measure | Value |\n|---|---|\n| Slope β | 5.27 years per log-point of income (a doubling of income ≈ +3.65 years) |\n| Robust standard error (HC3) | 0.211 |\n| 95% confidence interval | [4.85, 5.68] |\n| Intercept | 22.57 years |\n| Correlation r | 0.861 |\n| R² | 0.742 |\n| Prediction error (RMSE), model | 3.59 years |\n| Prediction error (RMSE), mean-only baseline | 7.08 years |\n\nThe interval sits well above zero, so the conclusion code is `positive_effect`. The ordinary standard error is similar (0.222), so the result doesn't depend on the robustness correction. Mean life expectancy by income group runs from 63.2 years (low income, 20 countries) to 79.7 years (high income, 73 countries).\n\n**Limitations:**\n- **Excluded countries are not a random set.** They include conflict-hit or sanctioned states (Syria, Yemen, South Sudan, Venezuela, North Korea) and small rich territories (Monaco, Liechtenstein). Leaving them out could move the slope either way, and I didn't test how much.\n- **The straight-line-in-log fit is a simplification.** The scatter suggests the curve flattens at high incomes, and I didn't formally test for curvature or influential points.\n- **Data quality is uneven.** Life expectancy appears to be modelled estimates, and 2023 values may be revised. The Central African Republic's earlier figures swing wildly (18.8 years in 2022); its 2023 value of 57.4 looks plausible and was kept.\n- **Scope:** this is one year, with each country weighted equally regardless of population. The confidence interval treats countries as a sample, even though 197 is close to all of them. The relationship is an association, not evidence that raising income causes longer lives.\n\nEverything is in `out/`. The report is `report.md`; `figure1.png` and `table1.csv` are the required figure and table; `analysis.py` regenerates the results. Supporting records are in `claims.json`, `exclusions.csv` and the `state/` folder."}],"container":null,"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":3724,"cache_read_input_tokens":24571,"output_tokens":1048,"output_tokens_details":{"thinking_tokens":92},"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":3724},"inference_geo":"global","iterations":[],"speed":"standard","fallback_credit":null},"input_transformations":[],"diagnostics":null,"context_management":null},"apiBlockIndex":1,"requestId":"req_011CgXk2iPdwdQK5cDqMhS42","requestRef":"7bca04e7-f693-4463-8942-48722e1ce325","requestedModel":"claude-opus-5-5","type":"assistant","uuid":"52798ebc-d760-4c2c-8534-abc957d1ed89","timestamp":"2026-10-30T03:52:09.463Z","effort":"medium","perTurnEffort":"medium","userType":"external","entrypoint":"sdk-cli","cwd":"/Users/simon-pierreboucher/wp29/runs/RP0016","sessionId":"19c13962-3714-4f87-bf1f-7bce5b43d66f","version":"2.1.314","gitBranch":"HEAD"}
