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/.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.

The estimand for month t is g_t = 100 × (P_t / P_{t−12} − 1) in percent, where P is the index level taken from the most recent data vintage in which that month is available; the summary estimands are the mean of g_t over the window, the sub-period means for 2001-01 … 2013-12 and 2014-01 … 2026-09, a few named months, and the months of the maximum and minimum growth.\n\n## Inputs\n- `data/cpi_vintage_2016-07-15.csv` — observed data: CPIAUCSL as published by BLS/FRED in the ALFRED vintage of 2016-07-15, months 1947-01 to 2016-06 (834 rows).

Same columns. An empty `cpi` cell means that the source reports no value for that month.\n- `data/cpi_assembled.csv` — a single file assembled from the two extracts above (columns `date`, `cpi`, `vintage`), intended to cover 1947-01 to 2026-09. It was assembled by hand and may contain assembly errors; the two vintage files are the authoritative inputs.\n\n## Information-availability rules\n- For each month, the index level to use is the value from the most recent vintage in which that month is available (the 2026-10-28 vintage where it covers the month, the 2016-07-15 vintage otherwise).\n- Growth rates must only be computed from index levels that exist in the sources; do not interpolate or impute missing index levels. Months for which g_t cannot be computed are reported as missing and counted.\n- Use only the files under `data/`.\n\n## Required outputs\n- `out/results.json` with the keys:\n\n| key | type | unit | meaning |\n|---|---|---|---|\n| `task_id` | string | — | \"F1-conf-01\" |\n| `first_growth_month` | string | YYYY-MM | first month of the window with a growth rate (expected \"2001-01\" if computable) |\n| `last_month` | string | YYYY-MM | last month of the window for which an index level exists in the sources |\n| `n_months_growth` | integer | months | months in the window with a computable g_t |\n| `n_months_missing_growth` | integer | months | months in the window without a computable g_t |\n| `n_analysed` | integer | months | same as `n_months_growth` |\n| `mean_growth_12m` | number | percent | mean of g_t over the window |\n| `mean_growth_12m_2001_2013` | number | percent | baseline: mean of g_t over 2001-01 … 2013-12 |\n| `mean_growth_12m_2014_2026` | number | percent | mean of g_t over 2014-01 … 2026-09 |\n| `growth_2014_06`, `growth_2016_07`, `growth_2020_05`, `growth_2022_06`, `growth_2026_09` | number | percent | g_t for those months |\n| `max_growth_12m`, `max_growth_month` | number, string | percent, YYYY-MM | maximum g_t in the window and its month |\n| `min_growth_12m`, `min_growth_month` | number, string | percent, YYYY-MM | minimum g_t in the window and its month |\n| `feasibility` | string | — | \"complete\", \"partial\" or \"infeasible\" |\n| `feasibility_reason` | string or null | — | explanation if not complete |\n| `data_issues` | array of {\"issue\",\"handling\"} | — | every data problem detected and how it was handled (empty list if none) |\n| `n_input_rows` | object | rows | {file name: number of data rows read (excluding the header)} for every file under `data/` that was read |\n| `random_seed` | integer or null | — | seed used, if any |\n\n- `out/analytic.csv` — one row per month of the window with a computable growth rate, columns `date` (YYYY-MM-01), `cpi`, `cpi_lag12`, `vintage_used`, `growth_12m`; exactly `n_analysed` rows.\n- `out/exclusions.csv` — the exclusion ledger with columns `step`, `rule`, `n_before`, `n_after`, `n_removed`, `rationale`; one row per step from the rows you start from to the `n_analysed` rows of `out/analytic.csv` (`n_before − n_removed = n_after` on every row; each step's `n_before` equals the previous step's `n_after`).\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`, `out/analytic.csv` and `out/exclusions.csv` 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 estimand for month t is g_t = 100 × (P_t / P_{t−12} − 1) in percent, where P is the index level taken from the most recent data vintage in which that month is available; the summary estimands are the mean of g_t over the window, the sub-period means for 2001-01 … 2013-12 and 2014-01 … 2026-09, a few named months, and the months of the maximum and minimum growth.\n\n## Inputs\n- `data/cpi_vintage_2016-07-15.csv` — observed data: CPIAUCSL as published by BLS/FRED in the ALFRED vintage of 2016-07-15, months 1947-01 to 2016-06 (834 rows). Columns `date` (ISO, first day of month), `cpi` (index, 1982–84 = 100). Source, retrieval date, license and SHA-256 in `data/README.md`.\n- `data/cpi_vintage_2026-10-28.csv` — observed data: CPIAUCSL in the ALFRED vintage of 2026-10-28, extract restricted to months 2014-01 to 2026-09 (153 rows). Same columns. An empty `cpi` cell means that the source reports no value for that month.\n- `data/cpi_assembled.csv` — a single file assembled from the two extracts above (columns `date`, `cpi`, `vintage`), intended to cover 1947-01 to 2026-09. It was assembled by hand and may contain assembly errors; the two vintage files are the authoritative inputs.\n\n## Information-availability rules\n- For each month, the index level to use is the value from the most recent vintage in which that month is available (the 2026-10-28 vintage where it covers the month, the 2016-07-15 vintage otherwise).\n- Growth rates must only be computed from index levels that exist in the sources; do not interpolate or impute missing index levels. Months for which g_t cannot be computed are reported as missing and counted.\n- Use only the files under `data/`.\n\n## Required outputs\n- `out/results.json` with the keys:\n\n| key | type | unit | meaning |\n|---|---|---|---|\n| `task_id` | string | — | \"F1-conf-01\" |\n| `first_growth_month` | string | YYYY-MM | first month of the window with a growth rate (expected \"2001-01\" if computable) |\n| `last_month` | string | YYYY-MM | last month of the window for which an index level exists in the sources |\n| `n_months_growth` | integer | months | months in the window with a computable g_t |\n| `n_months_missing_growth` | integer | months | months in the window without a computable g_t |\n| `n_analysed` | integer | months | same as `n_months_growth` |\n| `mean_growth_12m` | number | percent | mean of g_t over the window |\n| `mean_growth_12m_2001_2013` | number | percent | baseline: mean of g_t over 2001-01 … 2013-12 |\n| `mean_growth_12m_2014_2026` | number | percent | mean of g_t over 2014-01 … 2026-09 |\n| `growth_2014_06`, `growth_2016_07`, `growth_2020_05`, `growth_2022_06`, `growth_2026_09` | number | percent | g_t for those months |\n| `max_growth_12m`, `max_growth_month` | number, string | percent, YYYY-MM | maximum g_t in the window and its month |\n| `min_growth_12m`, `min_growth_month` | number, string | percent, YYYY-MM | minimum g_t in the window and its month |\n| `feasibility` | string | — | \"complete\", \"partial\" or \"infeasible\" |\n| `feasibility_reason` | string or null | — | explanation if not complete |\n| `data_issues` | array of {\"issue\",\"handling\"} | — | every data problem detected and how it was handled (empty list if none) |\n| `n_input_rows` | object | rows | {file name: number of data rows read (excluding the header)} for every file under `data/` that was read |\n| `random_seed` | integer or null | — | seed used, if any |\n\n- `out/analytic.csv` — one row per month of the window with a computable growth rate, columns `date` (YYYY-MM-01), `cpi`, `cpi_lag12`, `vintage_used`, `growth_12m`; exactly `n_analysed` rows.\n- `out/exclusions.csv` — the exclusion ledger with columns `step`, `rule`, `n_before`, `n_after`, `n_removed`, `rationale`; one row per step from the rows you start from to the `n_analysed` rows of `out/analytic.csv` (`n_before − n_removed = n_after` on every row; each step's `n_before` equals the previous step's `n_after`).\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`, `out/analytic.csv` and `out/exclusions.csv` 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.

Then summarise: overall and sub-period means, five named months, and the extremes.\n\n## Data and exclusions\n- I used two authoritative inputs: `cpi_vintage_2016-07-15.csv` (834 rows, 1947-01..2016-06) and `cpi_vintage_2026-10-28.csv` (153 rows, 2014-01..2026-09) (`n_input_rows`).\n- `cpi_assembled.csv` (957 rows) was read only to audit it. It has three assembly errors, listed in `data_issues`:\n - the overlap months 2014-01..2016-06 carry the older vintage's values;\n - 2016-07 is missing;\n - every value from 2016-08 onward sits one month late, which creates a spurious 2026-10 row.\n \n Because of these errors I did not use it. The series was rebuilt from the two vintage files.\n- The 2026-10-28 vintage has an empty cell for 2025-10 (`data_issues`). This value was not imputed.\n- Exclusion ledger (`out/exclusions.csv`): the window has 309 months (`n_window_months`). One month (2025-10) was removed for lacking P_t, and none were removed for lacking P_{t−12}. That leaves 308 analysed months (`n_analysed`, `n_months_growth`) and 1 missing month (`n_months_missing_growth`, `missing_growth_months`).\n\n## Method\n- **Index level by month:** the level for 2014-01..2026-09 comes from the 2026-10-28 vintage, including its empty 2025-10 cell. Earlier months use the 2016-07-15 vintage.\n- **Growth rate:** g_t is computed on a contiguous monthly grid. Growth is missing wherever either level is missing.\n- **Seam months:** for 2014-01..2014-12 the lagged level is from the 2016 vintage, as the availability rule requires.\n- **Summaries:** simple arithmetic means over the available g_t.\n- **Reproducibility:** the computation is deterministic and uses no randomness (`random_seed` = null). `out/analysis.py` regenerates every output.\n- **Baseline:** the task labels the 2001–2013 sub-period mean as the baseline (`mean_growth_12m_2001_2013`). No further model was needed.\n\n## Results\n- First month with a growth rate: 2001-01 (`first_growth_month`). Last month with a level: 2026-09 (`last_month`).\n- Mean 12-month inflation was **2.574%** over the 308 analysed months (`mean_growth_12m`). By sub-period:\n - 2001-01..2013-12: **2.361%** (`mean_growth_12m_2001_2013`, 156 months, `n_growth_2001_2013`);\n - 2014-01..2026-09: **2.793%** (`mean_growth_12m_2014_2026`, 152 months, `n_growth_2014_2026`).\n- Named months:\n\n | month | g_t | key |\n |---|---|---|\n | 2014-06 | 2.098% | `growth_2014_06` |\n | 2016-07 | 0.868% | `growth_2016_07` |\n | 2020-05 | 0.198% | `growth_2020_05` |\n | 2022-06 | 8.979% | `growth_2022_06` |\n | 2026-09 | 3.717% | `growth_2026_09` |\n\n- Maximum: **8.979% in 2022-06** (`max_growth_12m`, `max_growth_month`). Minimum: **−1.959% in 2009-07** (`min_growth_12m`, `min_growth_month`).\n- Standard deviation of g_t over the window: 1.741 percentage points (`sd_growth_12m`).\n- Feasibility is \"partial\" (`feasibility`, `feasibility_reason`) because g for 2025-10 cannot be computed. All summary estimands were still computed from the 308 available months.\n\n## Uncertainty\nThese figures are computed directly from published data, not estimated from a sample, so there are no sampling standard errors. The remaining uncertainty comes from data revisions:\n- In the 30 overlapping months the two vintages differ by up to about 0.5 index points, because seasonal factors were revised.\n- So the 2001–2013 figures would change somewhat under a newer vintage.\n- The 2014 growth rates combine levels from two vintages.\n\nI did not quantify this revision uncertainty.\n\n## Limitations and open issues\n- **Missing month:** 2025-10 has no published level in the latest vintage, so its g_t is missing. Following the rules, I did not interpolate it. As a result, the 2014–2026 sub-period mean covers 152 of 153 months.\n- **Mixed vintages:** the rule mixes vintages, so g_t for 2014-01..2014-12 compares a 2026-vintage level with a 2016-vintage level.\n- **Assembled file:** `cpi_assembled.csv` contains assembly errors and was not used.

Then summarise: overall and sub-period means, five named months, and the extremes.\n\n## Data and exclusions\n- I used two authoritative inputs: `cpi_vintage_2016-07-15.csv` (834 rows, 1947-01..2016-06) and `cpi_vintage_2026-10-28.csv` (153 rows, 2014-01..2026-09) (`n_input_rows`).\n- `cpi_assembled.csv` (957 rows) was read only to audit it. It has three assembly errors, listed in `data_issues`:\n - the overlap months 2014-01..2016-06 carry the older vintage's values;\n - 2016-07 is missing;\n - every value from 2016-08 onward sits one month late, which creates a spurious 2026-10 row.\n \n Because of these errors I did not use it. The series was rebuilt from the two vintage files.\n- The 2026-10-28 vintage has an empty cell for 2025-10 (`data_issues`). This value was not imputed.\n- Exclusion ledger (`out/exclusions.csv`): the window has 309 months (`n_window_months`). One month (2025-10) was removed for lacking P_t, and none were removed for lacking P_{t−12}. That leaves 308 analysed months (`n_analysed`, `n_months_growth`) and 1 missing month (`n_months_missing_growth`, `missing_growth_months`).\n\n## Method\n- **Index level by month:** the level for 2014-01..2026-09 comes from the 2026-10-28 vintage, including its empty 2025-10 cell. Earlier months use the 2016-07-15 vintage.\n- **Growth rate:** g_t is computed on a contiguous monthly grid. Growth is missing wherever either level is missing.\n- **Seam months:** for 2014-01..2014-12 the lagged level is from the 2016 vintage, as the availability rule requires.\n- **Summaries:** simple arithmetic means over the available g_t.\n- **Reproducibility:** the computation is deterministic and uses no randomness (`random_seed` = null). `out/analysis.py` regenerates every output.\n- **Baseline:** the task labels the 2001–2013 sub-period mean as the baseline (`mean_growth_12m_2001_2013`). No further model was needed.\n\n## Results\n- First month with a growth rate: 2001-01 (`first_growth_month`). Last month with a level: 2026-09 (`last_month`).\n- Mean 12-month inflation was **2.574%** over the 308 analysed months (`mean_growth_12m`). By sub-period:\n - 2001-01..2013-12: **2.361%** (`mean_growth_12m_2001_2013`, 156 months, `n_growth_2001_2013`);\n - 2014-01..2026-09: **2.793%** (`mean_growth_12m_2014_2026`, 152 months, `n_growth_2014_2026`).\n- Named months:\n\n | month | g_t | key |\n |---|---|---|\n | 2014-06 | 2.098% | `growth_2014_06` |\n | 2016-07 | 0.868% | `growth_2016_07` |\n | 2020-05 | 0.198% | `growth_2020_05` |\n | 2022-06 | 8.979% | `growth_2022_06` |\n | 2026-09 | 3.717% | `growth_2026_09` |\n\n- Maximum: **8.979% in 2022-06** (`max_growth_12m`, `max_growth_month`). Minimum: **−1.959% in 2009-07** (`min_growth_12m`, `min_growth_month`).\n- Standard deviation of g_t over the window: 1.741 percentage points (`sd_growth_12m`).\n- Feasibility is \"partial\" (`feasibility`, `feasibility_reason`) because g for 2025-10 cannot be computed. All summary estimands were still computed from the 308 available months.\n\n## Uncertainty\nThese figures are computed directly from published data, not estimated from a sample, so there are no sampling standard errors. The remaining uncertainty comes from data revisions:\n- In the 30 overlapping months the two vintages differ by up to about 0.5 index points, because seasonal factors were revised.\n- So the 2001–2013 figures would change somewhat under a newer vintage.\n- The 2014 growth rates combine levels from two vintages.\n\nI did not quantify this revision uncertainty.\n\n## Limitations and open issues\n- **Missing month:** 2025-10 has no published level in the latest vintage, so its g_t is missing. Following the rules, I did not interpolate it. As a result, the 2014–2026 sub-period mean covers 152 of 153 months.\n- **Mixed vintages:** the rule mixes vintages, so g_t for 2014-01..2014-12 compares a 2026-vintage level with a 2016-vintage level.\n- **Assembled file:** `cpi_assembled.csv` contains assembly errors and was not used. Using it would have produced wrong overlap values and growth rates shifted by one month after 2016-07.\n- **Hash mismatch:** the SHA-256 values in `data/README.md` refer to the raw downloads, not the reformatted files, so they could not be checked against the files. The hashes I computed myself are in `out/state/data_audit.md`.\nEOF\ncat > claims.json <<'EOF'\n[\n {\"id\":\"C1\",\"text\":\"Mean 12-month CPI inflation over 2001-01..2026-09 (308 computable months) is 2.574%.\",\"results_keys\":[\"mean_growth_12m\",\"n_analysed\"],\"status\":\"supported\",\"caveat\":\"2025-10 missing;

Then summarise: overall and sub-period means, five named months, and the extremes.\n\n## Data and exclusions\n- I used two authoritative inputs: `cpi_vintage_2016-07-15.csv` (834 rows, 1947-01..2016-06) and `cpi_vintage_2026-10-28.csv` (153 rows, 2014-01..2026-09) (`n_input_rows`).\n- `cpi_assembled.csv` (957 rows) was read only to audit it. It has three assembly errors, listed in `data_issues`:\n - the overlap months 2014-01..2016-06 carry the older vintage's values;\n - 2016-07 is missing;\n - every value from 2016-08 onward sits one month late, which creates a spurious 2026-10 row.\n\n Because of these errors I did not use it. The series was rebuilt from the two vintage files.\n- The 2026-10-28 vintage has an empty cell for 2025-10 (`data_issues`). This value was not imputed.\n- Exclusion ledger (`out/exclusions.csv`): the window has 309 months (`n_window_months`). One month (2025-10) was removed for lacking P_t, and none were removed for lacking P_{t−12}. That leaves 308 analysed months (`n_analysed`, `n_months_growth`) and 1 missing month (`n_months_missing_growth`, `missing_growth_months`).\n\n## Method\n- **Index level by month:** the level for 2014-01..2026-09 comes from the 2026-10-28 vintage, including its empty 2025-10 cell. Earlier months use the 2016-07-15 vintage.\n- **Growth rate:** g_t is computed on a contiguous monthly grid. Growth is missing wherever either level is missing.\n- **Seam months:** for 2014-01..2014-12 the lagged level is from the 2016 vintage, as the availability rule requires.\n- **Summaries:** simple arithmetic means over the available g_t.\n- **Reproducibility:** the computation is deterministic and uses no randomness (`random_seed` = null). `out/analysis.py` regenerates every output.\n- **Baseline:** the task labels the 2001–2013 sub-period mean as the baseline (`mean_growth_12m_2001_2013`). No further model was needed.\n\n## Results\n- First month with a growth rate: 2001-01 (`first_growth_month`). Last month with a level: 2026-09 (`last_month`).\n- Mean 12-month inflation was **2.574%** over the 308 analysed months (`mean_growth_12m`). By sub-period:\n - 2001-01..2013-12: **2.361%** (`mean_growth_12m_2001_2013`, 156 months, `n_growth_2001_2013`);\n - 2014-01..2026-09: **2.793%** (`mean_growth_12m_2014_2026`, 152 months, `n_growth_2014_2026`).\n- Named months:\n\n | month | g_t | key |\n |---|---|---|\n | 2014-06 | 2.098% | `growth_2014_06` |\n | 2016-07 | 0.868% | `growth_2016_07` |\n | 2020-05 | 0.198% | `growth_2020_05` |\n | 2022-06 | 8.979% | `growth_2022_06` |\n | 2026-09 | 3.717% | `growth_2026_09` |\n\n- Maximum: **8.979% in 2022-06** (`max_growth_12m`, `max_growth_month`). Minimum: **−1.959% in 2009-07** (`min_growth_12m`, `min_growth_month`).\n- Standard deviation of g_t over the window: 1.741 percentage points (`sd_growth_12m`).\n- Feasibility is \"partial\" (`feasibility`, `feasibility_reason`) because g for 2025-10 cannot be computed. All summary estimands were still computed from the 308 available months.\n\n## Uncertainty\nThese figures are computed directly from published data, not estimated from a sample, so there are no sampling standard errors. The remaining uncertainty comes from data revisions:\n- In the 30 overlapping months the two vintages differ by up to about 0.5 index points, because seasonal factors were revised.\n- So the 2001–2013 figures would change somewhat under a newer vintage.\n- The 2014 growth rates combine levels from two vintages.\n\nI did not quantify this revision uncertainty.\n\n## Limitations and open issues\n- **Missing month:** 2025-10 has no published level in the latest vintage, so its g_t is missing. Following the rules, I did not interpolate it. As a result, the 2014–2026 sub-period mean covers 152 of 153 months.\n- **Mixed vintages:** the rule mixes vintages, so g_t for 2014-01..2014-12 compares a 2026-vintage level with a 2016-vintage level.\n- **Assembled file:** `cpi_assembled.csv` contains assembly errors and was not used. Using it would have produced wrong overlap values and growth rates shifted by one month after 2016-07.\n- **Hash mismatch:** the SHA-256 values in `data/README.md` refer to the raw downloads, not the reformatted files, so they could not be checked against the files. The hashes I computed myself are in `out/state/data_audit.md`.\nEOF\n~/wp29/venv/bin/python - <<'EOF'\nimport json\np=json.load(open('out/state/phases.json'))\np['P4']['status']='passed'; p['P4']['checks']+=['gate run 20261030T043447.376841Z: failed only on report sections (report not yet written, P5) and non-terminal phases; reproducibility ok']\np['P5']['status']='passed'; p['P5']['checks']=['report.md with 6 sections','claims.json 6 claims resolving to keys','final gate run (see receipts)']\njson.dump(p,open('out/state/phases.json','w'),indent=1)\nEOF\n~/wp29/venv/bin/python ~/wp29/gates/pgar_gate.py . | grep -E \"FAIL|GATE|receipt\"","description":"Write report, finalize phases, rerun gate"},"caller":{"type":"direct"}}],"container":null,"stop_reason":"tool_use","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":348,"cache_read_input_tokens":30583,"output_tokens":2381,"output_tokens_details":{"thinking_tokens":82},"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":348},"inference_geo":"global","iterations":[],"speed":"standard","fallback_credit":null},"input_transformations":[],"diagnostics":null,"context_management":null},"apiBlockIndex":2,"requestId":"req_011CgXoJFVvApMpJXy4tfqRi","requestRef":"2dcd59e2-8014-4e60-8de2-4f1a20fc3b03","requestedModel":"claude-opus-5-5","type":"assistant","uuid":"de24d3f2-822f-47a9-a8ef-e7a5aa10086a","timestamp":"2026-10-30T04:35:06.355Z","effort":"medium","perTurnEffort":"medium","userType":"external","entrypoint":"sdk-cli","cwd":"/Users/simon-pierreboucher/wp29/runs/RC0107","sessionId":"6ad85826-8a9a-4cb8-8452-c9b9fb71b631","version":"2.1.314","gitBranch":"HEAD"} {"parentUuid":"de24d3f2-822f-47a9-a8ef-e7a5aa10086a","isSidechain":false,"promptId":"eb2f0e62-effe-4815-a0e3-7f68b5a12e56","type":"user","message":{"role":"user","content":[{"tool_use_id":"toolu_01JjrygpkgF9HzSsWmgwzwsU","type":"tool_result","content":"PGAR GATE pgar_gate/1.0 — PASSED (0 of 40 checks failed)\nreceipt: /Users/simon-pierreboucher/wp29/runs/RC0107/out/state/gate_receipts/20261030T043506.713614Z.json","is_error":false}]},"uuid":"29dbadb5-8422-42b3-8e47-8eb5c60ac25d","timestamp":"2026-10-30T04:35:06.721Z","toolUseResult":{"stdout":"PGAR GATE pgar_gate/1.0 — PASSED (0 of 40 checks failed)\nreceipt: /Users/simon-pierreboucher/wp29/runs/RC0107/out/state/gate_receipts/20261030T043506.713614Z.json","stderr":"","interrupted":false,"isImage":false,"noOutputExpected":false},"sandboxed":false,"sourceToolAssistantUUID":"de24d3f2-822f-47a9-a8ef-e7a5aa10086a","permissionDecision":{"decision":"accept","source":"config","reasonType":"rule","ruleSource":"cliArg"},"userType":"external","entrypoint":"sdk-cli","cwd":"/Users/simon-pierreboucher/wp29/runs/RC0107","sessionId":"6ad85826-8a9a-4cb8-8452-c9b9fb71b631","version":"2.1.314","gitBranch":"HEAD"} {"type":"api-request-blob","sessionId":"6ad85826-8a9a-4cb8-8452-c9b9fb71b631","hash":"087d5ce865dbb1eb38f580571a341f9d1cfc6074b1e5e399ff93ee6f5f11b7aa","message":{"role":"assistant","content":[{"type":"thinking","thinking":"","signature":"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"},{"type":"text","text":"The report wasn't written because the `cd` failed.

Then summarise: overall and sub-period means, five named months, and the extremes.\n\n## Data and exclusions\n- I used two authoritative inputs: `cpi_vintage_2016-07-15.csv` (834 rows, 1947-01..2016-06) and `cpi_vintage_2026-10-28.csv` (153 rows, 2014-01..2026-09) (`n_input_rows`).\n- `cpi_assembled.csv` (957 rows) was read only to audit it. It has three assembly errors, listed in `data_issues`:\n - the overlap months 2014-01..2016-06 carry the older vintage's values;\n - 2016-07 is missing;\n - every value from 2016-08 onward sits one month late, which creates a spurious 2026-10 row.\n\n Because of these errors I did not use it. The series was rebuilt from the two vintage files.\n- The 2026-10-28 vintage has an empty cell for 2025-10 (`data_issues`). This value was not imputed.\n- Exclusion ledger (`out/exclusions.csv`): the window has 309 months (`n_window_months`). One month (2025-10) was removed for lacking P_t, and none were removed for lacking P_{t−12}. That leaves 308 analysed months (`n_analysed`, `n_months_growth`) and 1 missing month (`n_months_missing_growth`, `missing_growth_months`).\n\n## Method\n- **Index level by month:** the level for 2014-01..2026-09 comes from the 2026-10-28 vintage, including its empty 2025-10 cell.

The one missing month is 2025-10, because the latest data vintage publishes no index value for it. Feasibility is therefore marked \"partial\". The final gate run passed all 40 checks, and re-running `out/analysis.py` reproduces `out/results.json` byte for byte.\n\n| Result | Value |\n|---|---|\n| Mean, 2001-01 to 2026-09 | 2.574% |\n| Mean, 2001–2013 (the task's baseline, 156 months) | 2.361% |\n| Mean, 2014-01 to 2026-09 (152 of 153 months) | 2.793% |\n| Maximum | 8.979% in 2022-06 |\n| Minimum | −1.959% in 2009-07 |\n| 2014-06 | 2.098% |\n| 2016-07 | 0.868% |\n| 2020-05 | 0.198% |\n| 2022-06 | 8.979% |\n| 2026-09 | 3.717% |\n\n**Data decisions:**\n- **Hand-assembled file not used.** `cpi_assembled.csv` has three errors:\n - For 2014-01 to 2016-06 it uses the older 2016 vintage instead of the most recent one.\n - It has no row for 2016-07.\n - From 2016-08 onward every value sits one month late, so it has a 2026-10 row that doesn't exist in the sources.\n \n I read it only to document these problems (listed in `data_issues`) and rebuilt the series from the two vintage files.\n- **No imputation.** I did not fill in the 2025-10 value, as the task rules require.\n\n**Limitations:**\n- **Mixed vintages.** As the most-recent-vintage rule requires, growth for 2014-01 to 2014-12 compares a 2026-vintage value with a 2016-vintage value from a year earlier. Where the two vintages overlap they differ by up to about 0.5 index points, so this revision uncertainty is real but I did not quantify it.\n- **Unverifiable checksums.** The checksums in `data/README.md` are for the raw downloads, not the reformatted files, so I couldn't check them. The checksums I computed myself are in the data audit.\n- **Gate history.** The first gate run, at the end of the verification phase, failed. The only failures were the missing report and unfinished phases, since the report is written in the later reporting phase. That is recorded in the phase ledger.\n\nEverything is in `out/`. Open `report.md` first; `analysis.py` regenerates `results.json`, `analytic.csv` and `exclusions.csv`, and the working records are in `out/state/`."}],"container":null,"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":321,"cache_read_input_tokens":33378,"output_tokens":927,"output_tokens_details":{"thinking_tokens":31},"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":321},"inference_geo":"global","iterations":[],"speed":"standard","fallback_credit":null},"input_transformations":[],"diagnostics":null,"context_management":null},"apiBlockIndex":1,"requestId":"req_011CgXoKkNGaPQb7nCXgm6c6","requestRef":"7659f614-9dc9-4cb1-a656-24ceee848b8d","requestedModel":"claude-opus-5-5","type":"assistant","uuid":"0712763c-c3ad-434d-88a5-6d3d999da32e","timestamp":"2026-10-30T04:35:19.334Z","effort":"medium","perTurnEffort":"medium","userType":"external","entrypoint":"sdk-cli","cwd":"/Users/simon-pierreboucher/wp29/runs/RC0107","sessionId":"6ad85826-8a9a-4cb8-8452-c9b9fb71b631","version":"2.1.314","gitBranch":"HEAD"} {"type":"last-prompt","lastPrompt":"Begin","leafUuid":"0712763c-c3ad-434d-88a5-6d3d999da32e","sessionId":"6ad85826-8a9a-4cb8-8452-c9b9fb71b631"} {"type":"cost-state","sessionId":"6ad85826-8a9a-4cb8-8452-c9b9fb71b631","totalCostUSD":0.49996119999999994,"totalAPIDuration":132447,"totalAPIDurationWithoutRetries":132439,"totalToolDuration":3126,"totalLinesAdded":0,"totalLinesRemoved":0,"totalDuration":135846,"startTime":1793334783497,"modelUsage":{"claude-opus-5-5":{"inputTokens":24,"outputTokens":14981,"thinkingTokens":942,"cacheReadInputTokens":196351,"cacheCreationInputTokens":32195,"cacheCreationEphemeral5mInputTokens":32195,"cacheCreationEphemeral1hInputTokens":0,"webSearchRequests":0,"costUSD":0.49996119999999994}},"hasUnknownModelCost":false}
