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"}],"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.

For each proposition, decide whether it is true (give a proof sketch) or false (give an explicit counterexample). For a false proposition, the counterexample must be made concrete: specify the joint construction of (X, Y), and produce a simulated sample from it that illustrates numerically that the marginals are normal while the sum is not (choose a construction whose departure from normality is clearly visible at the design sample size). The estimands are the truth values of propositions A and B and, for a false proposition, a verifiable counterexample.\n\n## Inputs\n- `data/propositions.csv` — columns `id`, `statement`: the two propositions (A and B) to assess.\n- `data/design.csv` — columns `parameter`, `value`, `description`: the random `seed` to use (`numpy.random.default_rng`) and the sample size `n` for the numerical illustration.\n\n## Information-availability rules\n- Use only the files under `data/`.

If no counterexample is provided, an empty object. |\n| `statement_b_true` | boolean | — | verdict on proposition B (the baseline check) |\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 | — | {\"propositions.csv\": rows read, \"design.csv\": rows read} |\n| `n_analysed` | integer or null | — | sample size of the simulated counterexample sample |\n| `random_seed` | integer or null | — | seed used |\n\n- `out/counterexample.csv` — columns `x`, `y`: the simulated sample of size n from the counterexample construction (only if a counterexample is provided).\n- `out/argument.md` — the mathematical argument: the proof sketch for the true proposition(s) and the explicit counterexample (with the reasoning that its marginals are normal and its sum is not) for the false proposition(s).\n- `out/report.md` with the sections: Question; Data and exclusions; Method; Results; Uncertainty; Limitations and open issues.

TRUE\nLet X ~ N(μ₁, σ₁²), Y ~ N(μ₂, σ₂²) be independent. Characteristic functions: φ_X(t) = exp(iμ₁t − σ₁²t²/2), φ_Y(t) = exp(iμ₂t − σ₂²t²/2).\nBy independence, φ_{X+Y}(t) = φ_X(t)φ_Y(t) = exp(i(μ₁+μ₂)t − (σ₁²+σ₂²)t²/2), which is the characteristic function of N(μ₁+μ₂, σ₁²+σ₂²).\nBy the uniqueness theorem for characteristic functions, X+Y ~ N(μ₁+μ₂, σ₁²+σ₂²) (degenerate cases included). ∎\n(More generally the result holds whenever (X, Y) is *jointly* Gaussian; independence of normal marginals is a special case.)\n\n## Proposition A — FALSE\nNormal marginals do not determine the joint law; only joint normality guarantees normal sums.\n\n**Note on the trivial candidate.** Y = −X gives X+Y ≡ 0, which is a degenerate normal under the stated convention, so it is *not* a counterexample. We need a sum that is neither constant nor normal.\n\n**Construction.** Let X ~ N(0,1) and let S be independent of X with P(S = 1) = P(S = −1) = 1/2. Define Y = S·X.\n\n1. *X is normal*: by definition.\n2. *Y is normal*: for any Borel B, P(Y ∈ B) = ½P(X ∈ B) + ½P(−X ∈ B) = P(X ∈ B), since −X has the same law as X (symmetry of N(0,1)). So Y ~ N(0,1).\n3. *X+Y is not normal*: X+Y = (1+S)X, which equals 0 when S = −1 and 2X when S = 1. Hence P(X+Y = 0) = P(S = −1) = 1/2 (plus P(X=0)·½ = 0).\n - A non-degenerate normal is absolutely continuous, so it gives probability 0 to every point; X+Y has an atom of mass 1/2 at 0 — not a non-degenerate normal.\n - X+Y is not constant: P(X+Y = 0) = 1/2 < 1, and on {S=1} it equals 2X, which is continuous.\n - Hence X+Y is not normal under any convention. Its law is ½δ₀ + ½N(0,4); E[X+Y]=0, Var(X+Y)=2.\n4. Remark: Cov(X,Y) = E[S]E[X²] = 0, so X and Y are uncorrelated yet not independent (|Y| = |X|), and the pair (X, Y) is not jointly Gaussian (if it were, uncorrelated would imply independent and X+Y would be N(0,2)).\n\n**Numerical illustration** (seed and n from data/design.csv; `out/counterexample.csv`, `out/analysis.py`): x and y have KS distances to fitted normals of about 0.002 (at the level of sampling noise), while x+y has KS distance ≈ 0.25 to its fitted normal and ≈ 50% exact zeros. See `out/results.json`.

Characteristic functions: φ_X(t) = exp(iμ₁t − σ₁²t²/2), φ_Y(t) = exp(iμ₂t − σ₂²t²/2).\nBy independence, φ_{X+Y}(t) = φ_X(t)φ_Y(t) = exp(i(μ₁+μ₂)t − (σ₁²+σ₂²)t²/2), which is the characteristic function of N(μ₁+μ₂, σ₁²+σ₂²).\nBy the uniqueness theorem for characteristic functions, X+Y ~ N(μ₁+μ₂, σ₁²+σ₂²) (degenerate cases included). ∎\n(More generally the result holds whenever (X, Y) is *jointly* Gaussian; independence of normal marginals is a special case.)\n\n## Proposition A — FALSE\nNormal marginals do not determine the joint law; only joint normality guarantees normal sums.\n\n**Note on the trivial candidate.** Y = −X gives X+Y ≡ 0, which is a degenerate normal under the stated convention, so it is *not* a counterexample. We need a sum that is neither constant nor normal.\n\n**Construction.** Let X ~ N(0,1) and let S be independent of X with P(S = 1) = P(S = −1) = 1/2. Define Y = S·X.\n\n1. *X is normal*: by definition.\n2. *Y is normal*: for any Borel B, P(Y ∈ B) = ½P(X ∈ B) + ½P(−X ∈ B) = P(X ∈ B), since −X has the same law as X (symmetry of N(0,1)). So Y ~ N(0,1).\n3. *X+Y is not normal*: X+Y = (1+S)X, which equals 0 when S = −1 and 2X when S = 1. Hence P(X+Y = 0) = P(S = −1) = 1/2 (plus P(X=0)·½ = 0).\n - A non-degenerate normal is absolutely continuous, so it gives probability 0 to every point; X+Y has an atom of mass 1/2 at 0 — not a non-degenerate normal.\n - X+Y is not constant: P(X+Y = 0) = 1/2 < 1, and on {S=1} it equals 2X, which is continuous.\n - Hence X+Y is not normal under any convention. Its law is ½δ₀ + ½N(0,4); E[X+Y]=0, Var(X+Y)=2.\n4. Remark: Cov(X,Y) = E[S]E[X²] = 0, so X and Y are uncorrelated yet not independent (|Y| = |X|), and the pair (X, Y) is not jointly Gaussian (if it were, uncorrelated would imply independent and X+Y would be N(0,2)).\n\n**Numerical illustration** (seed and n from data/design.csv; `out/counterexample.csv`, `out/analysis.py`): x and y have KS distances to fitted normals of about 0.002 (at the level of sampling noise), while x+y has KS distance ≈ 0.25 to its fitted normal and ≈ 50% exact zeros.

Proposition B: if X and Y are independent and each normal, then X+Y is normal. Decide each; give a proof sketch or a concrete counterexample.\n\n## Data and exclusions\nInputs: `data/propositions.csv` (2 rows) and `data/design.csv` (2 rows: seed 20261029, n 100000) — `n_input_rows`, `random_seed`. No data issues (`data_issues` is empty). No exclusions: all simulated rows are analysed (`n_analysed` = 100000; `out/exclusions.csv`). Hashes in `out/state/data_audit.md`.\n\n## Method\nVerdicts are by mathematical argument (`out/argument.md`). B: characteristic-function product + uniqueness. A: explicit counterexample X ~ N(0,1), S independent Rademacher, Y = S·X (`counterexample_values.construction`). The trivial Y = −X is rejected because its constant sum counts as normal under A's convention. The illustration simulates n draws with `numpy.random.default_rng(seed)` (`out/analysis.py`, `out/counterexample.csv`), and reports sample means/SDs (ddof=1) and the KS distance between the empirical law of x+y and the normal with its sample mean and SD. As a baseline, the same KS statistic is computed for the sum of two independent N(0,1) samples (`baseline_indep_ks_sum_vs_normal`).\n\n## Results\n- Proposition A is **false** (`statement_true` = false); counterexample provided (`counterexample_provided` = true).\n- Proposition B is **true** (`statement_b_true` = true).\n- Simulated marginals: mean_x ≈ −0.003, sd_x ≈ 0.998, mean_y ≈ −0.0002, sd_y ≈ 0.998 (`counterexample_values.mean_x`, `.sd_x`, `.mean_y`, `.sd_y`); KS distances to fitted normals ≈ 0.0021 and 0.0020 (`diagnostics.ks_x_vs_normal`, `diagnostics.ks_y_vs_normal`), below the asymptotic 5% critical value ≈ 0.0043 (`diagnostics.ks_critical_5pct`).\n- Sum: mean ≈ −0.004, sd ≈ 1.406 (`counterexample_values.mean_sum`, `.sd_sum`; theory 0 and √2); KS distance to fitted normal ≈ 0.251 (`counterexample_values.ks_sum_vs_normal`), driven by the atom: 50.05% of sums are exactly 0 (`diagnostics.frac_sum_exactly_zero`; theory 1/2).\n- Baseline: independent normal sum has KS ≈ 0.0020 (`baseline_indep_ks_sum_vs_normal`), sd ≈ 1.412 (`baseline_indep_sd_sum`).\n- Sample correlation of x and y ≈ −0.008 (`diagnostics.corr_xy`): uncorrelated yet dependent, so uncorrelated normal marginals are not enough.\n\n## Uncertainty\nThe verdicts are deterministic mathematical results and carry no statistical uncertainty. Simulated statistics carry Monte Carlo error of order 1/√n ≈ 0.003; the sum's KS distance (≈ 0.25) is about 60 times the 5% critical value, and theory gives a lower bound of 1/4 for any fitted normal because of the jump of size 1/2 at 0. (KS p-values with estimated parameters would be anti-conservative—Lilliefors issue—so they are not used as evidence.)\n\n## Limitations and open issues\n- What the illustration establishes: on this seeded sample, x and y look N(0,1) while x+y has a 50% atom at 0 and is far from any normal—consistent with the proof.\n- What it does not establish: a finite sample cannot prove that the marginals are exactly normal or that the sum is non-normal; those facts rest on the argument in `out/argument.md`. The B baseline simulation likewise does not prove B.\n- The KS-based marginal check is a single test; it would not detect tiny departures, which is irrelevant here since marginal normality of Y is proved by symmetry.\nEOF\ncat > out/claims.json <<'EOF'\n[\n {\"id\":\"C1\",\"text\":\"Proposition A is false: X~N(0,1), Y=S*X with S an independent Rademacher sign gives normal marginals but X+Y with an atom of mass 1/2 at 0, neither constant nor normal.\",\"results_keys\":[\"statement_true\",\"counterexample_provided\",\"counterexample_values\"],\"status\":\"supported\",\"caveat\":\"Truth rests on the proof in out/argument.md;

Proposition B: if X and Y are independent and each normal, then X+Y is normal. Decide each; give a proof sketch or a concrete counterexample.\n\n## Data and exclusions\nInputs: `data/propositions.csv` (2 rows) and `data/design.csv` (2 rows: seed 20261029, n 100000) — `n_input_rows`, `random_seed`. No data issues (`data_issues` is empty). No exclusions: all simulated rows are analysed (`n_analysed` = 100000; `out/exclusions.csv`). Hashes in `out/state/data_audit.md`.\n\n## Method\nVerdicts are by mathematical argument (`out/argument.md`). B: characteristic-function product + uniqueness. A: explicit counterexample X ~ N(0,1), S independent Rademacher, Y = S·X (`counterexample_values.construction`). The trivial Y = −X is rejected because its constant sum counts as normal under A's convention. The illustration simulates n draws with `numpy.random.default_rng(seed)` (`out/analysis.py`, `out/counterexample.csv`), and reports sample means/SDs (ddof=1) and the KS distance between the empirical law of x+y and the normal with its sample mean and SD. As a baseline, the same KS statistic is computed for the sum of two independent N(0,1) samples (`baseline_indep_ks_sum_vs_normal`).\n\n## Results\n- Proposition A is **false** (`statement_true` = false); counterexample provided (`counterexample_provided` = true).\n- Proposition B is **true** (`statement_b_true` = true).\n- Simulated marginals: mean_x ≈ −0.003, sd_x ≈ 0.998, mean_y ≈ −0.0002, sd_y ≈ 0.998 (`counterexample_values.mean_x`, `.sd_x`, `.mean_y`, `.sd_y`); KS distances to fitted normals ≈ 0.0021 and 0.0020 (`diagnostics.ks_x_vs_normal`, `diagnostics.ks_y_vs_normal`), below the asymptotic 5% critical value ≈ 0.0043 (`diagnostics.ks_critical_5pct`).\n- Sum: mean ≈ −0.004, sd ≈ 1.406 (`counterexample_values.mean_sum`, `.sd_sum`; theory 0 and √2); KS distance to fitted normal ≈ 0.251 (`counterexample_values.ks_sum_vs_normal`), driven by the atom: 50.05% of sums are exactly 0 (`diagnostics.frac_sum_exactly_zero`; theory 1/2).\n- Baseline: independent normal sum has KS ≈ 0.0020 (`baseline_indep_ks_sum_vs_normal`), sd ≈ 1.412 (`baseline_indep_sd_sum`).\n- Sample correlation of x and y ≈ −0.008 (`diagnostics.corr_xy`): uncorrelated yet dependent, so uncorrelated normal marginals are not enough.\n\n## Uncertainty\nThe verdicts are deterministic mathematical results and carry no statistical uncertainty. Simulated statistics carry Monte Carlo error of order 1/√n ≈ 0.003; the sum's KS distance (≈ 0.25) is about 60 times the 5% critical value, and theory gives a lower bound of 1/4 for any fitted normal because of the jump of size 1/2 at 0. (KS p-values with estimated parameters would be anti-conservative—Lilliefors issue—so they are not used as evidence.)\n\n## Limitations and open issues\n- What the illustration establishes: on this seeded sample, x and y look N(0,1) while x+y has a 50% atom at 0 and is far from any normal—consistent with the proof.\n- What it does not establish: a finite sample cannot prove that the marginals are exactly normal or that the sum is non-normal; those facts rest on the argument in `out/argument.md`.

The final gate run passes all 27 checks, and running `out/analysis.py` again produces exactly the same results.\n\n**Proposition B (true): if X and Y are independent and each normal, X + Y is normal.** The proof multiplies the two characteristic functions and uses the fact that a characteristic function determines the distribution. The result is X + Y ~ N(μ₁+μ₂, σ₁²+σ₂²).\n\n**Proposition A (false): normal X and normal Y do not guarantee a normal X + Y.**\n- **Why the obvious example doesn't work:** Y = −X gives X + Y = 0, a constant. The task counts a constant as a normal, so that is not a counterexample.\n- **Counterexample used:** X ~ N(0,1), and S is a random sign (+1 or −1, each with probability ½) independent of X. Set Y = S·X.\n- **Why it works:** Y ~ N(0,1) because the normal distribution is symmetric. But X + Y = (1+S)X is exactly 0 half the time and 2X otherwise. A non-constant normal can't put probability ½ on a single point, and the sum isn't constant either, so it isn't normal under any reading.\n- **Side point:** X and Y are uncorrelated but not independent, so the pair is not jointly normal.\n\n**Simulation** (the task's seed 20261029, n = 100,000):\n\n| | x | y | x + y |\n|---|---|---|---|\n| Sample SD | 0.998 | 0.998 | 1.406 (theory √2) |\n| Distance from a fitted normal (KS statistic) | 0.0021 | 0.0020 | 0.251 |\n| Share exactly zero | — | — | 50.05% |\n\nFor comparison, the 5% cutoff for the KS distance is about 0.0043. The baseline sum of two independent normals has a KS distance of 0.0020.\n\n**Limitation:** the simulation only illustrates the result. A finite sample can't prove that the marginals are exactly normal or that the sum isn't. Both verdicts rest on the written arguments in `out/argument.md`. I also didn't report KS p-values, because they are too optimistic when the normal's mean and SD are estimated from the same data.\n\nFiles are in `out/`:\n- results.json\n- counterexample.csv\n- argument.md\n- report.md\n- claims.json\n- analysis.py\n- exclusions.csv (no rows excluded)\n- state/ (contract, data audit, checks, log, phase ledger, gate receipts)"}],"container":null,"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":308,"cache_read_input_tokens":21058,"output_tokens":844,"output_tokens_details":{"thinking_tokens":0},"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":308},"inference_geo":"global","iterations":[],"speed":"standard","fallback_credit":null},"input_transformations":[],"diagnostics":null,"context_management":null},"apiBlockIndex":0,"requestId":"req_011CgXpxjgFX28mmvfCJRurh","requestRef":"adc97da7-a269-4b4c-9ff7-f9aa1abbfd16","requestedModel":"claude-opus-5-5","type":"assistant","uuid":"d1d5bd81-3644-484a-8350-75f6866bbdfa","timestamp":"2026-10-30T04:56:47.400Z","effort":"medium","perTurnEffort":"medium","userType":"external","entrypoint":"sdk-cli","cwd":"/Users/simon-pierreboucher/wp29/runs/RC0190","sessionId":"574909dc-30fe-4e55-8cf4-a44262cf7a11","version":"2.1.314","gitBranch":"HEAD"}78{"type":"last-prompt","lastPrompt":"Begin","leafUuid":"d1d5bd81-3644-484a-8350-75f6866bbdfa","sessionId":"574909dc-30fe-4e55-8cf4-a44262cf7a11"}79{"type":"cost-state","sessionId":"574909dc-30fe-4e55-8cf4-a44262cf7a11","totalCostUSD":0.3613984,"totalAPIDuration":100360,"totalAPIDurationWithoutRetries":100356,"totalToolDuration":4535,"totalLinesAdded":0,"totalLinesRemoved":0,"totalDuration":105091,"startTime":1793336102317,"modelUsage":{"claude-opus-5-5":{"inputTokens":28,"outputTokens":11618,"thinkingTokens":944,"cacheReadInputTokens":148082,"cacheCreationInputTokens":19862,"cacheCreationEphemeral5mInputTokens":19862,"cacheCreationEphemeral1hInputTokens":0,"webSearchRequests":0,"costUSD":0.3613984}},"hasUnknownModelCost":false}80
