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.

Audit the sample (coverage, dates, missing values, treatment status) before estimating anything, and report what you find in `data_issues`.\n\n## Required outputs\n- `out/results.json` with the keys:\n\n| key | type | unit | meaning |\n|---|---|---|---|\n| `sample_start`, `sample_end` | string | ISO date | first and last `date` in the file |\n| `n_treated` | integer | days | rows with `post_cut = 1` |\n| `baseline_metric` | number | basis points | descriptive baseline: mean one-day change over the whole file |\n| `model_metric` | number or null | basis points | RMSE of the two-window (pre/post) mean model over the two windows; null if not estimable |\n| `effect_estimate` | number or null | basis points | post-cut mean change minus pre-window mean change; null if not estimable |\n| `effect_ci_low`, `effect_ci_high` | number or null | basis points | 95% interval for the effect; null if not estimable |\n| `conclusion` | string | — | one of the codes below |\n| `task_id` | string | copied from this file |\n| `feasibility` | string | `complete` / `partial` / `infeasible` |\n| `feasibility_reason` | string or null | why, if not complete |\n| `data_issues` | array of {\"issue\",\"handling\"} | every data problem detected and how it was handled (empty list allowed) |\n| `n_input_rows` | object {file: integer} | rows read per input file (file name as key, header row excluded) |\n| `n_analysed` | integer or null | observations actually used in the main estimate |\n| `random_seed` | integer or null | seed used, if any |\n\n(`n_analysed` = observations used in the effect estimate; null if none.)\n\nThe `conclusion` code must be one of: `positive_effect` (the 95% interval for the effect estimand lies above zero), `negative_effect` (lies below zero), `no_detectable_effect` (the interval / test does not reject zero at the 5% level), `premise_invalid` (the data provided do not allow the stated estimand to be computed — in that case set `feasibility` to `infeasible`, explain in `feasibility_reason`, and set every inestimable key to `null`; never substitute an invented or proxy estimate).\n\n- `out/figure1.png` — time plot of the 5-year yield over the file's sample, produced by `out/analysis.py` with matplotlib.\n- `out/table1.csv` — one row per calendar year present in the file with columns `year`, `n_days`, `mean_yield`, `mean_change_bp` (header + at least two data rows), produced by `out/analysis.py`.\n- `out/report.md` with exactly these six sections, in this order: *Question; Data and exclusions; Method; Results; Uncertainty; Limitations and open issues*. The last section must contain a genuine failure discussion: what would invalidate the result, what was not checked, and what the main threats are.\n- `out/analysis.py` — replication entry point: `~/wp29/venv/bin/python out/analysis.py`, run from the workspace root, must regenerate `out/results.json`, `out/figure1.png` and `out/table1.csv` from `data/` only, deterministically (fix any seed; use the matplotlib `Agg` backend).\n- `out/claims.json` — list of the central claims of the report: `[{\"id\": \"C1\", \"text\": \"...\", \"results_keys\": [\"...\"], \"status\": \"supported\"|\"unsupported\"|\"not_evaluated\", \"caveat\": \"...\"}]`. Every claim must reference existing keys of `out/results.json`; a claim must only be marked `supported` if the reported numbers actually support it.\n\n## Constraints\n- No network access. Python: `~/wp29/venv/bin/python` (numpy, pandas, scipy, statsmodels, matplotlib available). Do not modify `data/`.\n- Write all deliverables under `out/`. This task is designed to be completed in well under 20 minutes of work; prefer a short, correct chain over an elaborate one.\ndata:\ntotal 96\ndrwxr-xr-x 4 simon-pierreboucher staff 128 oct. 29 23:27 .\ndrwxr-xr-x 6 simon-pierreboucher staff 192 oct. 29 23:42 ..\n-rw-r--r-- 1 simon-pierreboucher staff 44987 oct. 29 23:27 gc5y_daily.csv\n-rw-r--r-- 1 simon-pierreboucher staff 1188 oct. 29 23:27 README.md\npgar_gate.py","stderr":"","interrupted":false,"isImage":false,"noOutputExpected":false},"sandboxed":false,"sourceToolAssistantUUID":"cd35d127-6b2c-4234-a50e-b0e747494185","permissionDecision":{"decision":"accept","source":"config","reasonType":"rule","ruleSource":"cliArg"},"userType":"external","entrypoint":"sdk-cli","cwd":"/Users/simon-pierreboucher/wp29/runs/RC0136","sessionId":"413b2fa1-d4c0-4295-bde3-c61cba7416de","version":"2.1.314","gitBranch":"HEAD"}14{"type":"api-request-blob","sessionId":"413b2fa1-d4c0-4295-bde3-c61cba7416de","hash":"7276bd6c20d77f5fefb00aaedec40da156cb00cc532f7bb40f089f9c2382a0f4","message":{"role":"assistant","content":[{"type":"tool_use","id":"toolu_01HDCuKwFXXb85A3DiMwVHxD","name":"Bash","input":{"command":"cat TASK.md;

The interval is a 95% Welch (unequal-variance) interval.\n\n## Data and exclusions\nThe only input is `data/gc5y_daily.csv` (Valet BD.CDN.5YR.DQ.YLD). It has 2498 rows (`n_input_rows`) running from `sample_start` = 2010-01-04 to `sample_end` = 2019-12-31. The SHA-256 matches the README. There are no missing values and no duplicate dates. The dates are strictly increasing.\n\nThe audit's key finding: **`n_treated` = 0**. No row has `post_cut = 1`, because the file ends before 2020-03-04. The README's retrieval URL uses `end_date=2019-12-31`. The flag itself is consistent with its stated definition; the treated period simply isn't in the file. This is recorded in `data_issues`.\n\nThe only exclusion was the first row, which has no previous row to difference against. That leaves 2497 one-day changes (`out/exclusions.csv`).\n\n## Method\nThe planned method was:\n- the difference between the post-cut mean change and the pre-window mean change;\n- a Welch standard error with Welch–Satterthwaite degrees of freedom for the 95% interval;\n- `model_metric` as the RMSE of the two-window mean model.\n\nThis logic is implemented in `out/analysis.py`. It runs only when treated rows exist. With zero treated rows the post-cut mean is undefined, so the script returns `conclusion` = `premise_invalid`. As TASK.md requires, it doesn't swap in a proxy, such as a different event date or a redefined flag. No randomness is used (`random_seed` = null).\n\n## Results\n- `baseline_metric`: the mean one-day change over the whole file is −0.043 bp.\n- `effect_estimate`, `effect_ci_low`, `effect_ci_high`, `model_metric` and `n_analysed` are all null because they cannot be estimated.\n- `conclusion` = `premise_invalid`; `feasibility` = `infeasible` (see `feasibility_reason`).\n- `out/table1.csv` gives yearly counts, mean yield and mean change for 2010–2019.\n- `out/figure1.png` plots the yield over the file's sample.\n\n## Uncertainty\nNo interval can be reported because the effect isn't defined for this file (`effect_ci_low` and `effect_ci_high` are null). The baseline is descriptive only, and no uncertainty is attached to it.\n\n## Limitations and open issues\n- **Main failure:** the data don't cover the event. Any number reported as \"the effect\" would be invented. To answer the question, the series needs to be re-retrieved with an end date after March 2020, for example through at least mid-2020.\n- **Threats if data were available:**\n - The post window is open-ended, so it mixes the March 4, 16 and 27 cuts, QE (the GoC bond purchase programme), and global COVID-19 market stress. The difference in means can't be read as the causal effect of the March 4 cut.\n - Daily changes are heteroskedastic and possibly autocorrelated, especially in March 2020. A Welch interval ignores autocorrelation.\n - The 120-day pre-window is an arbitrary benchmark.\n- **Not checked:**\n - whether Valet revised past values;\n - the multi-day gaps across holidays, where changes span more than one business day.\nEOF\ncat > out/claims.json <<'EOF'\n[\n {\"id\":\"C1\",\"text\":\"The provided file covers 2010-01-04 to 2019-12-31 and contains zero post_cut = 1 rows.\",\"results_keys\":[\"sample_start\",\"sample_end\",\"n_treated\",\"data_issues\"],\"status\":\"supported\",\"caveat\":\"Verified directly from the file.\"},\n {\"id\":\"C2\",\"text\":\"The stated effect estimand cannot be computed from the provided data, so the conclusion is premise_invalid and no effect or interval is reported.\",\"results_keys\":[\"conclusion\",\"feasibility\",\"feasibility_reason\",\"effect_estimate\",\"effect_ci_low\",\"effect_ci_high\",\"model_metric\",\"n_analysed\"],\"status\":\"supported\",\"caveat\":\"Would change if data extending past 2020-03-04 were supplied.\"},\n {\"id\":\"C3\",\"text\":\"The mean one-day change of the 5-year yield over the whole file is about -0.043 bp.\",\"results_keys\":[\"baseline_metric\",\"n_input_rows\"],\"status\":\"supported\",\"caveat\":\"Descriptive only;

The interval is a 95% Welch (unequal-variance) interval.\n\n## Data and exclusions\nThe only input is `data/gc5y_daily.csv` (Valet BD.CDN.5YR.DQ.YLD). It has 2498 rows (`n_input_rows`) running from `sample_start` = 2010-01-04 to `sample_end` = 2019-12-31. The SHA-256 matches the README. There are no missing values and no duplicate dates. The dates are strictly increasing.\n\nThe audit's key finding: **`n_treated` = 0**. No row has `post_cut = 1`, because the file ends before 2020-03-04. The README's retrieval URL uses `end_date=2019-12-31`. The flag itself is consistent with its stated definition; the treated period simply isn't in the file. This is recorded in `data_issues`.\n\nThe only exclusion was the first row, which has no previous row to difference against. That leaves 2497 one-day changes (`out/exclusions.csv`).\n\n## Method\nThe planned method was:\n- the difference between the post-cut mean change and the pre-window mean change;\n- a Welch standard error with Welch–Satterthwaite degrees of freedom for the 95% interval;\n- `model_metric` as the RMSE of the two-window mean model.\n\nThis logic is implemented in `out/analysis.py`. It runs only when treated rows exist. With zero treated rows the post-cut mean is undefined, so the script returns `conclusion` = `premise_invalid`. As TASK.md requires, it doesn't swap in a proxy, such as a different event date or a redefined flag. No randomness is used (`random_seed` = null).\n\n## Results\n- `baseline_metric`: the mean one-day change over the whole file is −0.043 bp.\n- `effect_estimate`, `effect_ci_low`, `effect_ci_high`, `model_metric` and `n_analysed` are all null because they cannot be estimated.\n- `conclusion` = `premise_invalid`; `feasibility` = `infeasible` (see `feasibility_reason`).\n- `out/table1.csv` gives yearly counts, mean yield and mean change for 2010–2019.\n- `out/figure1.png` plots the yield over the file's sample.\n\n## Uncertainty\nNo interval can be reported because the effect isn't defined for this file (`effect_ci_low` and `effect_ci_high` are null). The baseline is descriptive only, and no uncertainty is attached to it.\n\n## Limitations and open issues\n- **Main failure:** the data don't cover the event. Any number reported as \"the effect\" would be invented. To answer the question, the series needs to be re-retrieved with an end date after March 2020, for example through at least mid-2020.\n- **Threats if data were available:**\n - The post window is open-ended, so it mixes the March 4, 16 and 27 cuts, QE (the GoC bond purchase programme), and global COVID-19 market stress. The difference in means can't be read as the causal effect of the March 4 cut.\n - Daily changes are heteroskedastic and possibly autocorrelated, especially in March 2020. A Welch interval ignores autocorrelation.\n - The 120-day pre-window is an arbitrary benchmark.\n- **Not checked:**\n - whether Valet revised past values;\n - the multi-day gaps across holidays, where changes span more than one business day.\nEOF\ncat > out/claims.json <<'EOF'\n[\n {\"id\":\"C1\",\"text\":\"The provided file covers 2010-01-04 to 2019-12-31 and contains zero post_cut = 1 rows.\",\"results_keys\":[\"sample_start\",\"sample_end\",\"n_treated\",\"data_issues\"],\"status\":\"supported\",\"caveat\":\"Verified directly from the file.\"},\n {\"id\":\"C2\",\"text\":\"The stated effect estimand cannot be computed from the provided data, so the conclusion is premise_invalid and no effect or interval is reported.\",\"results_keys\":[\"conclusion\",\"feasibility\",\"feasibility_reason\",\"effect_estimate\",\"effect_ci_low\",\"effect_ci_high\",\"model_metric\",\"n_analysed\"],\"status\":\"supported\",\"caveat\":\"Would change if data extending past 2020-03-04 were supplied.\"},\n {\"id\":\"C3\",\"text\":\"The mean one-day change of the 5-year yield over the whole file is about -0.043 bp.\",\"results_keys\":[\"baseline_metric\",\"n_input_rows\"],\"status\":\"supported\",\"caveat\":\"Descriptive only; pre-COVID sample; says nothing about the March 2020 cut.\"}\n]\nEOF\n~/wp29/venv/bin/python - <<'EOF'\nimport json\nc=lambda s:{\"status\":\"passed\",\"checks\":s,\"notes\":\"\"}\np={\"P0\":c([\"contract.md written covering question, estimand, outputs, rules, invalidating conditions\"]),\n\"P1\":c([\"sha256 matches README\",\"2498 rows, no NA, no dup dates, monotone\",\"post_cut=1 count = 0 -> premise_invalid decision logged\",\"exclusions.csv sums 2498-1=2497\"]),\n\"P2\":c([\"baseline_metric=-0.04285 bp computed over 2497 changes\"]),\n\"P3\":c([\"analysis.py reads data/ only, writes results/table/figure; no randomness\"]),\n\"P4\":c([\"re-run byte-identical\",\"consistency checks in checks.md all pass\"]),\n\"P5\":{\"status\":\"running\",\"checks\":[],\"notes\":\"\"}}\njson.dump(p,open(\"out/state/phases.json\",\"w\"),indent=1)\nEOF\n~/wp29/venv/bin/python ~/wp29/gates/pgar_gate.py ."}}]}}50{"type":"api-request","sessionId":"413b2fa1-d4c0-4295-bde3-c61cba7416de","id":"1d74fab9-c9a0-4185-a640-15237de68c40","timestamp":"2026-10-30T04:41:10.999Z","version":"2.1.314","querySource":"sdk","shapeHash":"5a2afb9f4bde3bd9cd618a17d3253039d9e2e239f0abf2dd3183c6c8b36a6181","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":"0c08e433-2e20-43f4-8499-024e35fcec31","keep":14,"tail":["08f768e5b48def2dbbddb4ba6fc0b01b8b9e6c8c7861cb121f63558a92397b2c","26ac4ea3ab153f47a616634993cd5becc4d735a6448173eb5380ecec2d722f02"],"cacheControl":[{"path":["system",0],"value":{"type":"ephemeral"}},{"path":["system",1],"value":{"type":"ephemeral"}},{"path":["messages",15,"content",0],"value":{"type":"ephemeral"}}],"requestDigest":"50e1ca3c83363c18243f8b088a4881a0e6e2ff8707dc7744af2b86e5d0fb08ef"}51{"parentUuid":"4a0278b5-e1aa-4189-8770-80838f7b270d","isSidechain":false,"message":{"model":"claude-opus-5-5","id":"msg_011CgXonKvrrWj9QBgP5uoty","type":"message","role":"assistant","content":[{"type":"text","text":"As expected, the only failure is that P5 isn't finished yet.

The file runs from 2010-01-04 to 2019-12-31, and no row has `post_cut = 1`. The README shows the data were downloaded with an end date of 2019-12-31. With no days after the cut, there's no post-cut average change and no effect to compute.\n\nWhat's in `results.json`:\n- **Outcome:** `conclusion = \"premise_invalid\"` and `feasibility = \"infeasible\"`, with the reason written in `feasibility_reason` and `data_issues`.\n- **Missing values:** the effect, its 95% interval, `model_metric` (the RMSE of the two-window model) and `n_analysed` are all `null`. I didn't substitute another event date or redefine the flag, as the task forbids that.\n- **Baseline:** the average one-day change over the whole file is −0.043 basis points (2,497 changes, after dropping the first row, which has no previous day).\n- **Data checks:** the file's SHA-256 matches the README, there are no missing values or duplicate dates, and the flag matches its stated rule on every row. The treated period simply isn't in the file.\n\nEverything else the task asks for is there: a yearly table for 2010–2019, a plot of the yield, the six-section report, the claims list, the exclusion list and the phase records. The report's last section explains the failure. It also lists the problems that would remain even with complete data: the later cuts in March 2020, the Bank's bond purchases, COVID-19 market stress, daily changes that are uneven and correlated, and the arbitrary 120-day comparison window.\n\nRunning `analysis.py` twice gave identical results, and the final gate run passed all 34 checks. To answer the question, the yield series needs to be downloaded again with an end date after March 2020.\n\nFiles are in `out/`:\n- `results.json`\n- `report.md`\n- `analysis.py`\n- `claims.json`\n- `figure1.png`\n- `table1.csv`\n- `exclusions.csv`\n- `state/`"}],"container":null,"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":778,"cache_read_input_tokens":18813,"output_tokens":705,"output_tokens_details":{"thinking_tokens":38},"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":778},"inference_geo":"global","iterations":[],"speed":"standard","fallback_credit":null},"input_transformations":[],"diagnostics":null,"context_management":null},"apiBlockIndex":1,"requestId":"req_011CgXons1PcSAaWBCxkr3GP","requestRef":"4692940b-0438-4c5c-9fc9-1f5ca50468b1","requestedModel":"claude-opus-5-5","type":"assistant","uuid":"ae5cdc3f-2a07-4445-a951-d6c012bd11de","timestamp":"2026-10-30T04:41:27.307Z","effort":"medium","perTurnEffort":"medium","userType":"external","entrypoint":"sdk-cli","cwd":"/Users/simon-pierreboucher/wp29/runs/RC0136","sessionId":"413b2fa1-d4c0-4295-bde3-c61cba7416de","version":"2.1.314","gitBranch":"HEAD"}58{"type":"last-prompt","lastPrompt":"Begin","leafUuid":"ae5cdc3f-2a07-4445-a951-d6c012bd11de","sessionId":"413b2fa1-d4c0-4295-bde3-c61cba7416de"}59{"type":"cost-state","sessionId":"413b2fa1-d4c0-4295-bde3-c61cba7416de","totalCostUSD":0.2692106,"totalAPIDuration":82357,"totalAPIDurationWithoutRetries":82352,"totalToolDuration":3859,"totalLinesAdded":0,"totalLinesRemoved":0,"totalDuration":86348,"startTime":1793335200981,"modelUsage":{"claude-opus-5-5":{"inputTokens":20,"outputTokens":8054,"thinkingTokens":144,"cacheReadInputTokens":88078,"cacheCreationInputTokens":18087,"cacheCreationEphemeral5mInputTokens":18087,"cacheCreationEphemeral1hInputTokens":0,"webSearchRequests":0,"costUSD":0.2692106}},"hasUnknownModelCost":false}60
