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\nEXECUTABLE GATES (additional, mandatory)\n- A read-only gate program is provided at `~/wp29/gates/pgar_gate.py`. Run it from the workspace root as `~/wp29/venv/bin/python ~/wp29/gates/pgar_gate.py .` It checks the output contract of `TASK.md` (required files, keys, types, finite values, report sections, the claims ledger, the phase ledger, the exclusion ledger) and reproducibility (it re-runs `out/analysis.py` in a temporary copy and compares the regenerated `out/results.json` with yours). It never checks scientific correctness and it contains no reference answers.\n- You must run the gate at the end of P4 and again at the end of P5, and record each run's receipt (the gate writes `out/state/gate_receipts/<timestamp>.json`) in `out/state/phases.json`. You may not declare the task complete while the latest gate receipt reports `\"passed\": false`. Fix the reported problems and re-run the gate.\n- The controller will run the same gate after your session ends. If it fails, you will be resumed with the gate output and asked to fix the problems; each such cycle consumes your remaining budget.\n\nSEPARATE REVIEW (additional)\n- After the gate passes, a separate reviewer session that has not seen your work in progress will examine `TASK.md` and everything under `out/` and may return a list of issues (file `out/review/review.json`). You will then be resumed once to address them: fix what is justified, explain in `out/report.md` (Limitations and open issues) what you disagree with, re-run the gate, and update `out/claims.json` and `out/state/phases.json`. The reviewer has no reference answers; its role is to challenge unsupported claims, violated information rules, unverified computations, and inconsistencies between your report and your results.\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 population slope β in the linear projection y = α + βx + ε, and its sampling uncertainty must account for the fact that observations from the same firm share a common firm-level shock (observations are independent across firms, not within firms).\n\n## Inputs\n- `data/panel.csv` — simulated data (this is a synthetic dataset generated for this exercise; it is not observed data). Columns: `firm_id` (integer firm identifier), `x` (regressor, dimensionless), `y` (outcome, dimensionless). One row per firm–observation pair; rows are in random order.\n\n## Information-availability rules\n- Use only `data/panel.csv`. No other input exists.\n\n## Required outputs\n- `out/results.json` with the keys:\n\n| key | type | meaning |\n|---|---|---|\n| `task_id` | string | \"F2-smoke-01\" |\n| `beta_hat` | number | OLS slope estimate of y on x (with intercept) |\n| `alpha_hat` | number | OLS intercept |\n| `se_ols` | number | conventional (homoskedastic, non-clustered) OLS standard error of the slope — the naïve baseline |\n| `se_cluster` | number | standard error of the slope clustered by `firm_id` |\n| `beta_ci_low`, `beta_ci_high` | number | 95% confidence interval for β using the clustered standard error |\n| `n_analysed` | integer | observations used |\n| `n_clusters` | integer | number of firms |\n| `feasibility` | string | \"complete\", \"partial\" or \"infeasible\" |\n| `feasibility_reason` | string or null | explanation if not complete |\n| `data_issues` | array of {\"issue\",\"handling\"} | data problems detected and how handled (empty list if none) |\n| `n_input_rows` | object | {\"panel.csv\": rows read} |\n| `random_seed` | integer or null | seed used, if any |\n\n- `out/report.md` with the sections: Question; Data and exclusions; Method; Results; Uncertainty; Limitations and open issues.\n- `out/analysis.py` — running `~/wp29/venv/bin/python out/analysis.py` from the workspace root must regenerate `out/results.json` from `data/` only, deterministically.\n- `out/claims.json` — a list of the central claims of the report: [{\"id\": \"C1\", \"text\": \"...\", \"results_keys\": [\"...\"], \"status\": \"supported\"|\"unsupported\"|\"not_evaluated\", \"caveat\": \"...\"}].\n\n## Constraints\n- No network access.

The panel is balanced, with 50 firms (`n_clusters`) of 40 rows each (`obs_per_cluster_min`, `obs_per_cluster_max`). I applied no exclusions (see `out/exclusions.csv`, where every step removed 0 rows), so 2000 observations were analysed (`n_analysed`). No data problems were found (`data_issues` is empty).\n\n## Method\nI ran OLS of y on x with an intercept. The conventional homoskedastic standard error is the naïve baseline (`se_ols`). The main standard error is cluster-robust by `firm_id` (`se_cluster`). It uses the sandwich (X'X)⁻¹ [Σ_g X_g'e_g e_g'X_g] (X'X)⁻¹ with the CR1 small-sample factor G/(G−1)·(N−1)/(N−K) (`cluster_se_correction`). The 95% CI is beta_hat ± t₀.₉₇₅,G−1 · se_cluster, with G−1 = 49 df (`ci_critical_value_t_df`, `ci_critical_value`). The method involves no randomness (`random_seed` = null). Estimates match statsmodels exactly (see `out/state/checks.md`).\n\n## Results\n- Slope: beta_hat = 0.8051 (`beta_hat`). Intercept: alpha_hat = 1.4440 (`alpha_hat`).\n- Firm-clustered SE = 0.0731 (`se_cluster`). Conventional OLS SE = 0.0241 (`se_ols`).\n- 95% CI for β using the clustered SE: [0.6581, 0.9521] (`beta_ci_low`, `beta_ci_high`). The CI excludes 0.\n\n## Uncertainty\nThe clustered SE is about 3.03 times the naïve SE (`se_ratio_cluster_to_ols`). This fits the strong within-firm dependence found in the audit: firm means account for about 45% of the variance of x and about 53% of the variance of the OLS residuals. Treating the 2000 observations as independent would therefore greatly overstate precision. With 50 balanced clusters, cluster-robust inference based on t(49) is standard and should be reasonably reliable.\n\n## Limitations and open issues\n- β is a linear-projection (association) coefficient, not a causal effect. Because x is correlated within firms, β pools within-firm and between-firm variation, and I did not estimate firm fixed effects (the task did not ask for them).\n- Cluster-robust inference is asymptotic in the number of clusters. 50 clusters is adequate, but the CI is approximate. I did not run a wild cluster bootstrap.\n- The data are synthetic, as stated in TASK.md.\nEOF\ncat > out/claims.json <<'EOF'\n[\n {\"id\":\"C1\",\"text\":\"The OLS slope of y on x (with intercept) is about 0.805, with intercept about 1.444, using all 2000 observations from 50 firms.\",\"results_keys\":[\"beta_hat\",\"alpha_hat\",\"n_analysed\",\"n_clusters\"],\"status\":\"supported\",\"caveat\":\"Linear projection coefficient, not causal.\"},\n {\"id\":\"C2\",\"text\":\"The firm-clustered (CR1) SE of the slope is about 0.073, and the 95% CI (t with 49 df) is about [0.658, 0.952], which excludes zero.\",\"results_keys\":[\"se_cluster\",\"beta_ci_low\",\"beta_ci_high\",\"ci_critical_value\"],\"status\":\"supported\",\"caveat\":\"Asymptotic in the number of clusters (G=50).\"},\n {\"id\":\"C3\",\"text\":\"The conventional OLS SE (about 0.024) is roughly 3 times smaller than the clustered SE, so ignoring within-firm dependence overstates precision.\",\"results_keys\":[\"se_ols\",\"se_cluster\",\"se_ratio_cluster_to_ols\"],\"status\":\"supported\",\"caveat\":\"The variance shares quoted as the explanation come from the audit, not from results.json.\"},\n {\"id\":\"C4\",\"text\":\"The data have no missing values, no duplicate rows, and no exclusions.\",\"results_keys\":[\"data_issues\",\"n_input_rows\",\"n_analysed\"],\"status\":\"supported\",\"caveat\":\"\"}\n]\nEOF\ncat > out/state/phases.json <<'EOF'\n{\"P0\":{\"status\":\"passed\",\"checks\":[\"contract.md written covering question, estimand, outputs, info rules, invalidity\"],\"notes\":\"\"},\n \"P1\":{\"status\":\"passed\",\"checks\":[\"sha256, shape, dtypes, missing, duplicates, cluster sizes recorded in data_audit.md\",\"exclusions.csv: 2000-0=2000\"],\"notes\":\"\"},\n \"P2\":{\"status\":\"passed\",\"checks\":[\"se_ols baseline computed and matches statsmodels\"],\"notes\":\"\"},\n \"P3\":{\"status\":\"passed\",\"checks\":[\"analysis.py runs and writes results.json;

The panel is balanced, with 50 firms (`n_clusters`) of 40 rows each (`obs_per_cluster_min`, `obs_per_cluster_max`). I applied no exclusions (see `out/exclusions.csv`, where every step removed 0 rows), so 2000 observations were analysed (`n_analysed`). No data problems were found (`data_issues` is empty).\n\n## Method\nI ran OLS of y on x with an intercept. The conventional homoskedastic standard error is the naïve baseline (`se_ols`). The main standard error is cluster-robust by `firm_id` (`se_cluster`). It uses the sandwich (X'X)⁻¹ [Σ_g X_g'e_g e_g'X_g] (X'X)⁻¹ with the CR1 small-sample factor G/(G−1)·(N−1)/(N−K) (`cluster_se_correction`). The 95% CI is beta_hat ± t₀.₉₇₅,G−1 · se_cluster, with G−1 = 49 df (`ci_critical_value_t_df`, `ci_critical_value`). The method involves no randomness (`random_seed` = null). Estimates match statsmodels exactly (see `out/state/checks.md`).\n\n## Results\n- Slope: beta_hat = 0.8051 (`beta_hat`). Intercept: alpha_hat = 1.4440 (`alpha_hat`).\n- Firm-clustered SE = 0.0731 (`se_cluster`). Conventional OLS SE = 0.0241 (`se_ols`).\n- 95% CI for β using the clustered SE: [0.6581, 0.9521] (`beta_ci_low`, `beta_ci_high`). The CI excludes 0.\n\n## Uncertainty\nThe clustered SE is about 3.03 times the naïve SE (`se_ratio_cluster_to_ols`). This fits the strong within-firm dependence found in the audit (`out/state/data_audit.md`, not a results key): firm means account for about 45% of the variance of x and about 53% of the variance of the OLS residuals. Treating the 2000 observations as independent would therefore greatly overstate precision. With 50 balanced clusters, cluster-robust inference based on t(49) is standard and should be reasonably reliable.\n\n## Limitations and open issues\n- β is a linear-projection (association) coefficient, not a causal effect. Because x is correlated within firms, β pools within-firm and between-firm variation, and I did not estimate firm fixed effects (the task did not ask for them).\n- Cluster-robust inference is asymptotic in the number of clusters. 50 clusters is adequate, but the CI is approximate.

there are no missing values and no duplicate rows. The panel is balanced, with 50 firms (`n_clusters`) of 40 rows each (`obs_per_cluster_min`, `obs_per_cluster_max`). I applied no exclusions (see `out/exclusions.csv`, where every step removed 0 rows), so 2000 observations were analysed (`n_analysed`). No data problems were found (`data_issues` is empty).\n\n## Method\nI ran OLS of y on x with an intercept. The conventional homoskedastic standard error is the naïve baseline (`se_ols`). The main standard error is cluster-robust by `firm_id` (`se_cluster`). It uses the sandwich (X'X)⁻¹ [Σ_g X_g'e_g e_g'X_g] (X'X)⁻¹ with the CR1 small-sample factor G/(G−1)·(N−1)/(N−K) (`cluster_se_correction`). The 95% CI is beta_hat ± t₀.₉₇₅,G−1 · se_cluster, with G−1 = 49 df (`ci_critical_value_t_df`, `ci_critical_value`). The method involves no randomness (`random_seed` = null). Estimates match statsmodels exactly (see `out/state/checks.md`).\n\n## Results\n- Slope: beta_hat = 0.8051 (`beta_hat`). Intercept: alpha_hat = 1.4440 (`alpha_hat`).\n- Firm-clustered SE = 0.0731 (`se_cluster`). Conventional OLS SE = 0.0241 (`se_ols`).\n- 95% CI for β using the clustered SE: [0.6581, 0.9521] (`beta_ci_low`, `beta_ci_high`). The CI excludes 0.\n\n## Uncertainty\nThe clustered SE is about 3.03 times the naïve SE (`se_ratio_cluster_to_ols`). This fits the strong within-firm dependence found in the audit (`out/state/data_audit.md`, not a results key): firm means account for about 45% of the variance of x and about 53% of the variance of the OLS residuals. Treating the 2000 observations as independent would therefore greatly overstate precision. With 50 balanced clusters, cluster-robust inference based on t(49) is standard and should be reasonably reliable.\n\n## Limitations and open issues\n- β is a linear-projection (association) coefficient, not a causal effect. Because x is correlated within firms, β pools within-firm and between-firm variation, and I did not estimate firm fixed effects (the task did not ask for them).\n- Cluster-robust inference is asymptotic in the number of clusters. 50 clusters is adequate, but the CI is approximate. I did not run a wild cluster bootstrap.\n- The data are synthetic, as stated in TASK.md.\nEOF\ncat > out/claims.json <<'EOF'\n[\n {\"id\":\"C1\",\"text\":\"The OLS slope of y on x (with intercept) is about 0.805, with intercept about 1.444, using all 2000 observations from 50 firms.\",\"results_keys\":[\"beta_hat\",\"alpha_hat\",\"n_analysed\",\"n_clusters\"],\"status\":\"supported\",\"caveat\":\"Linear projection coefficient, not causal.\"},\n {\"id\":\"C2\",\"text\":\"The firm-clustered (CR1) SE of the slope is about 0.073, and the 95% CI (t with 49 df) is about [0.658, 0.952], which excludes zero.\",\"results_keys\":[\"se_cluster\",\"beta_ci_low\",\"beta_ci_high\",\"ci_critical_value\"],\"status\":\"supported\",\"caveat\":\"Asymptotic in the number of clusters (G=50).\"},\n {\"id\":\"C3\",\"text\":\"The conventional OLS SE (about 0.024) is roughly 3 times smaller than the clustered SE, so ignoring within-firm dependence overstates precision.\",\"results_keys\":[\"se_ols\",\"se_cluster\",\"se_ratio_cluster_to_ols\"],\"status\":\"supported\",\"caveat\":\"The variance shares quoted as the explanation come from the audit, not from results.json.\"},\n {\"id\":\"C4\",\"text\":\"The data have no missing values, no duplicate rows, and no exclusions.\",\"results_keys\":[\"data_issues\",\"n_input_rows\",\"n_analysed\"],\"status\":\"supported\",\"caveat\":\"\"}\n]\nEOF\ncat > out/state/phases.json <<'EOF'\n{\"P0\":{\"status\":\"passed\",\"checks\":[\"contract.md written covering question, estimand, outputs, info rules, invalidity\"],\"notes\":\"\"},\n \"P1\":{\"status\":\"passed\",\"checks\":[\"sha256, shape, dtypes, missing, duplicates, cluster sizes recorded in data_audit.md\",\"exclusions.csv: 2000-0=2000\"],\"notes\":\"\"},\n \"P2\":{\"status\":\"passed\",\"checks\":[\"se_ols baseline computed and matches statsmodels\"],\"notes\":\"\"},\n \"P3\":{\"status\":\"passed\",\"checks\":[\"analysis.py runs and writes results.json; no randomness\"],\"notes\":\"\"},\n \"P4\":{\"status\":\"running\",\"checks\":[\"rerun byte-identical\",\"statsmodels cross-check of beta, se_ols, se_cluster\",\"CI contains estimate, SE>0, counts add up\"],\"notes\":\"\"},\n \"P5\":{\"status\":\"pending\",\"checks\":[],\"notes\":\"\"}}\nEOF\n~/wp29/venv/bin/python ~/wp29/gates/pgar_gate.py .; ls out/state/gate_receipts","description":"Rewrite report, claims, phases at root; run gate"}}]}}53{"type":"api-request","sessionId":"c9b24f02-ecdc-44d1-851d-ac03de1dd1da","id":"cd00e290-424e-41a6-8768-29d9921b1d7a","timestamp":"2026-10-30T03:33:37.472Z","version":"2.1.314","querySource":"sdk","shapeHash":"16f1312ca64cc9e7b0a8358eef1c8b2b95746216b2f24870fca3df7268279898","params":{"model":"claude-opus-5-5","betas":["claude-code-20250219","interleaved-thinking-2025-05-14","context-management-2025-06-27","prompt-caching-scope-2026-01-05","per-turn-control-2026-07-01","thinking-token-count-2026-05-13","mid-conversation-system-clear-at-2026-08-21","effort-2025-11-24","thinking-binding-controls-2026-08-01","thinking-display-updates-2026-08-18","cache-diagnosis-2026-04-07"],"max_tokens":128000,"thinking":{"type":"adaptive","display":"updates"},"context_management":{"edits":[{"type":"clear_thinking_20251015","keep":"all"}]},"output_config":{"effort":"medium"}},"base":"ba108f17-323c-4ec9-b033-ec1462a114b6","keep":14,"tail":["402252602f8142d063072c26bc5691ee576375d6b2b1ec8135508095a4252e50","96eab5f7d18b2cd46ddbdbba5f66b811edc1ab2f20d4930ffc0a0bc76136aa27"],"cacheControl":[{"path":["system",0],"value":{"type":"ephemeral"}},{"path":["system",1],"value":{"type":"ephemeral"}},{"path":["messages",15,"content",0],"value":{"type":"ephemeral"}}],"requestDigest":"a842ffa387b628b5ff2260637ecccb59ea489fbe9cc7abc77b459cf0dbd6d1dc"}54{"parentUuid":"cebc01f9-746b-47f8-9f76-502bb532be9a","isSidechain":false,"message":{"model":"claude-opus-5-5","id":"msg_011CgXidXLrrDxUqYHQtfyeU","type":"message","role":"assistant","content":[{"type":"text","text":"The only failure is the expected one: P4 and P5 were not yet marked as finished.

task is done. The slope of y on x is about 0.805, with a 95% confidence interval of [0.658, 0.952] after clustering by firm. The final gate run passed all 32 checks, and running `out/analysis.py` again produces an identical `out/results.json`.\n\n| Quantity | Value |\n|---|---|\n| Slope (`beta_hat`) | 0.8051 |\n| Intercept (`alpha_hat`) | 1.4440 |\n| Standard error, conventional OLS (`se_ols`, the naïve baseline) | 0.0241 |\n| Standard error, clustered by firm (`se_cluster`) | 0.0731 |\n| 95% confidence interval | [0.6581, 0.9521] |\n| Observations used / firms | 2000 / 50 |\n\n- **Data:** the file is clean. It has no missing values and no duplicate rows, and every firm has exactly 40 rows. I excluded nothing.\n- **Clustering matters a lot:** the clustered standard error is about 3 times the conventional one. Within-firm correlation is strong: firm averages account for about 45% of the variation in x and 53% of the variation in the residuals. Ignoring this would make the estimate look far more precise than it is.\n- **Method choice:** the task didn't specify a small-sample correction or how to build the interval. I used the common Stata-style adjustment and a t-distribution with 49 degrees of freedom (one less than the number of firms). The slope and both standard errors match statsmodels exactly.\n\n**Limitations:**\n- The slope measures association, not a causal effect.\n- It mixes variation within firms and between firms; I didn't add firm fixed effects because the task didn't ask for them.\n- The interval is approximate, though 50 firms is generally enough for this kind of clustered inference.\n- The data are synthetic, as the task states.\n\nEverything is in `out/`; open `report.md` first. It also contains `results.json`, `analysis.py`, `claims.json` and `exclusions.csv`, plus working notes and gate receipts under `out/state/`."}],"container":null,"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":301,"cache_read_input_tokens":16622,"output_tokens":698,"output_tokens_details":{"thinking_tokens":17},"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":301},"inference_geo":"global","iterations":[],"speed":"standard","fallback_credit":null},"input_transformations":[],"diagnostics":null,"context_management":null},"apiBlockIndex":1,"requestId":"req_011CgXie9jdZCgGXGntnRGMB","requestRef":"3f3acadb-19c7-4a61-bbb1-f1037586b9f5","requestedModel":"claude-opus-5-5","type":"assistant","uuid":"29e22a84-d1cc-46eb-ada1-6a6ea448487f","timestamp":"2026-10-30T03:33:52.745Z","effort":"medium","perTurnEffort":"medium","userType":"external","entrypoint":"sdk-cli","cwd":"/Users/simon-pierreboucher/wp29/runs/RD0002","sessionId":"c9b24f02-ecdc-44d1-851d-ac03de1dd1da","version":"2.1.314","gitBranch":"HEAD"}67{"type":"last-prompt","lastPrompt":"Begin","leafUuid":"29e22a84-d1cc-46eb-ada1-6a6ea448487f","sessionId":"c9b24f02-ecdc-44d1-851d-ac03de1dd1da"}68{"type":"cost-state","sessionId":"c9b24f02-ecdc-44d1-851d-ac03de1dd1da","totalCostUSD":0.30337340000000007,"totalAPIDuration":83687,"totalAPIDurationWithoutRetries":83678,"totalToolDuration":13215,"totalLinesAdded":0,"totalLinesRemoved":0,"totalDuration":100072,"startTime":1793331132681,"modelUsage":{"claude-opus-5-5":{"inputTokens":22,"outputTokens":10009,"thinkingTokens":281,"cacheReadInputTokens":92452,"cacheCreationInputTokens":16923,"cacheCreationEphemeral5mInputTokens":16923,"cacheCreationEphemeral1hInputTokens":0,"webSearchRequests":0,"costUSD":0.30337340000000007}},"hasUnknownModelCost":false}69
