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.

This mini-project asks what happened to the Government of Canada 5-year benchmark bond yield afterwards: the estimand is the average one-day change of the 5-year yield (basis points) on trading days flagged `post_cut = 1` minus the average one-day change on the 120 trading days immediately preceding the first flagged day, with a 95% interval that allows unequal variances in the two windows.

It comes with a 95% Welch (unequal-variance) interval. **The estimand cannot be computed from the file provided. The conclusion is `premise_invalid` (`conclusion`), with `feasibility` = `infeasible`.**\n\n## Data and exclusions\n- `data/gc5y_daily.csv`: 2498 rows (`n_input_rows`). SHA-256 matches the README. There are no missing values, no duplicate dates, the dates are strictly increasing, and the gaps match business-daily data (full audit in `out/state/data_audit.md`).\n- The sample runs from 2010-01-04 (`sample_start`) to 2019-12-31 (`sample_end`). The README confirms the series was retrieved with `end_date=2019-12-31`.\n- **No row has `post_cut = 1` (`n_treated` = 0).** The file ends more than two months before the 2020-03-04 cut. So the post-cut window is empty, and the 120-day pre-window cannot be defined because it is anchored on the first flagged day. This is recorded in `data_issues`.\n- Exclusion ledger (`out/exclusions.csv`): 2498 rows loaded. Taking first differences leaves 2497 one-day changes (the baseline sample). Selecting the estimation windows leaves 0 rows. `n_analysed` is therefore null.\n\n## Method\n- One-day change = 100·(y_t − y_{t−1}) between consecutive rows, dated t. `post_cut` is used exactly as provided.\n- Baseline: the mean one-day change over the whole file.\n- Planned main method, implemented in `out/analysis.py` but not executable on this file: difference in means between the post window and the pre window, with a Welch-Satterthwaite t interval. `model_metric` would be the RMSE of the two-window mean model.\n- I deliberately used no proxy. Examples would be treating the last 120 days of 2019 as \"pre\" or picking another event date. Either would redefine the treatment, which `TASK.md` forbids. No randomness is used (`random_seed` = null).\n\n## Results\n- Baseline mean one-day change over 2010–2019: −0.0429 bp/day (`baseline_metric`). This equals the total 2010→2019 decline (2.75% → 1.68%) divided by 2497 changes.\n- `effect_estimate`, `effect_ci_low`, `effect_ci_high` and `model_metric` are null: not estimable.\n- `conclusion` = `premise_invalid`. The reason is given in `feasibility_reason`.\n- Figure 1 (`out/figure1.png`) plots the yield over 2010–2019. Table 1 (`out/table1.csv`) gives yearly n_days, mean yield and mean change. These outputs describe the sample only and do not inform the estimand.\n\n## Uncertainty\nNo interval can be reported for the effect (`effect_ci_low`/`effect_ci_high` are null). The baseline (`baseline_metric`) is a descriptive average, and I attach no inferential interval to it. Daily yield changes are autocorrelated and heteroskedastic, so a naive i.i.d. standard error would understate its uncertainty.\n\n## Limitations and open issues\n- **Main failure:** the input lacks the treatment period entirely, so the scientific question cannot be answered from it. The fix would be to re-retrieve BD.CDN.5YR.DQ.YLD with an end date after March 2020. I did not do this because there is no network access and only the provided file may be used.\n- If corrected data were supplied, these threats would remain:\n  - The windows overlap the COVID-19 market shock. A pre/post difference in means would mix the policy cut with flight-to-quality, liquidity stress and further cuts (2020-03-13, 2020-03-27) and asset purchases, so it is not a causal effect of the 2020-03-04 cut.\n  - The Welch interval assumes independent daily changes within each window.

It comes with a 95% Welch (unequal-variance) interval. **The estimand cannot be computed from the file provided. The conclusion is `premise_invalid` (`conclusion`), with `feasibility` = `infeasible`.**\n\n## Data and exclusions\n- `data/gc5y_daily.csv`: 2498 rows (`n_input_rows`). SHA-256 matches the README. There are no missing values, no duplicate dates, the dates are strictly increasing, and the gaps match business-daily data (full audit in `out/state/data_audit.md`).\n- The sample runs from 2010-01-04 (`sample_start`) to 2019-12-31 (`sample_end`). The README confirms the series was retrieved with `end_date=2019-12-31`.\n- **No row has `post_cut = 1` (`n_treated` = 0).** The file ends more than two months before the 2020-03-04 cut. So the post-cut window is empty, and the 120-day pre-window cannot be defined because it is anchored on the first flagged day. This is recorded in `data_issues`.\n- Exclusion ledger (`out/exclusions.csv`): 2498 rows loaded. Taking first differences leaves 2497 one-day changes (the baseline sample). Selecting the estimation windows leaves 0 rows. `n_analysed` is therefore null.\n\n## Method\n- One-day change = 100·(y_t − y_{t−1}) between consecutive rows, dated t. `post_cut` is used exactly as provided.\n- Baseline: the mean one-day change over the whole file.\n- Planned main method, implemented in `out/analysis.py` but not executable on this file: difference in means between the post window and the pre window, with a Welch-Satterthwaite t interval. `model_metric` would be the RMSE of the two-window mean model.\n- I deliberately used no proxy. Examples would be treating the last 120 days of 2019 as \"pre\" or picking another event date. Either would redefine the treatment, which `TASK.md` forbids. No randomness is used (`random_seed` = null).\n\n## Results\n- Baseline mean one-day change over 2010–2019: −0.0429 bp/day (`baseline_metric`). This equals the total 2010→2019 decline (2.75% → 1.68%) divided by 2497 changes.\n- `effect_estimate`, `effect_ci_low`, `effect_ci_high` and `model_metric` are null: not estimable.\n- `conclusion` = `premise_invalid`. The reason is given in `feasibility_reason`.\n- Figure 1 (`out/figure1.png`) plots the yield over 2010–2019. Table 1 (`out/table1.csv`) gives yearly n_days, mean yield and mean change. These outputs describe the sample only and do not inform the estimand.\n\n## Uncertainty\nNo interval can be reported for the effect (`effect_ci_low`/`effect_ci_high` are null). The baseline (`baseline_metric`) is a descriptive average, and I attach no inferential interval to it. Daily yield changes are autocorrelated and heteroskedastic, so a naive i.i.d. standard error would understate its uncertainty.\n\n## Limitations and open issues\n- **Main failure:** the input lacks the treatment period entirely, so the scientific question cannot be answered from it. The fix would be to re-retrieve BD.CDN.5YR.DQ.YLD with an end date after March 2020. I did not do this because there is no network access and only the provided file may be used.\n- If corrected data were supplied, these threats would remain:\n  - The windows overlap the COVID-19 market shock. A pre/post difference in means would mix the policy cut with flight-to-quality, liquidity stress and further cuts (2020-03-13, 2020-03-27) and asset purchases, so it is not a causal effect of the 2020-03-04 cut.\n  - The Welch interval assumes independent daily changes within each window. Volatility clustering in March 2020 would make it too narrow.\n  - The result could change with the length of the post window (all flagged days through the end of the file).\n- Not checked: the yields against an independent source; whether yields published after release were revised; and whether `post_cut` flags were set correctly for 2020 dates (none exist here).\nEOF\ncat > out/claims.json <<'EOF'\n[\n {\"id\":\"C1\",\"text\":\"The file contains no rows with post_cut = 1; it covers 2010-01-04 to 2019-12-31, ending before the 2020-03-04 cut.\",\"results_keys\":[\"n_treated\",\"sample_start\",\"sample_end\"],\"status\":\"supported\",\"caveat\":\"Based on the file as provided; the README confirms retrieval end_date 2019-12-31.\"},\n {\"id\":\"C2\",\"text\":\"The estimand (post-cut minus pre-window mean one-day change) and its 95% interval cannot be computed; conclusion is premise_invalid and the task is infeasible.\",\"results_keys\":[\"effect_estimate\",\"effect_ci_low\",\"effect_ci_high\",\"model_metric\",\"conclusion\",\"feasibility\",\"feasibility_reason\",\"n_analysed\"],\"status\":\"supported\",\"caveat\":\"No proxy estimate was substituted.\"},\n {\"id\":\"C3\",\"text\":\"The descriptive baseline mean one-day change of the 5-year yield over the whole file is about -0.043 bp per day.\",\"results_keys\":[\"baseline_metric\",\"n_input_rows\"],\"status\":\"supported\",\"caveat\":\"Descriptive only; uninformative about the March-2020 cut; no interval attached.\"}\n]\nEOF\necho \"- 2026-10-30 P2/P3 passed (baseline -0.0429 bp; analysis.py writes all outputs).

The yield file ends on 2019-12-31, more than two months before the Bank of Canada's 2020-03-04 emergency cut, so no day in it is flagged as post-cut.\n\n**What the data show:**\n- The file has 2,498 business days from 2010-01-04 to 2019-12-31. There are no missing values or duplicate dates, and its checksum matches the one in the data's README file.\n- Every day has `post_cut = 0`. So there is no post-cut period to average, and the 120-day comparison period, which is counted back from the first flagged day, has no starting point.\n- The README explains why: the series was downloaded with an end date of 2019-12-31.\n\n**What I reported:**\n- **Conclusion:** `premise_invalid`, with feasibility marked `infeasible` and the reason written out.\n- **Not estimated (left as null):** the effect, its 95% interval, the error measure for the before/after model, and the number of days used.\n- **No substitute estimate:** using the last 120 days of 2019 or a different event date would redefine the treatment, which the task forbids.\n- **Simple baseline:** across the whole file the yield fell by an average of −0.0429 basis points per day. That is just the total drop from 2.75% to 1.68% spread over 2,497 daily changes. It describes the 2010–2019 sample and says nothing about the cut.\n\n**Deliverables:** everything is in `out/`.\n- `out/analysis.py` rebuilds the results, `figure1.png` (the yield over 2010–2019) and `table1.csv` (one row per year, 2010–2019) from the data. A clean re-run gave byte-identical results.\n- `out/report.md` has the six required sections and `out/claims.json` lists three claims, each tied to a results key.\n- The working records are in `out/exclusions.csv` and `out/state/`.\n- The final run of the output gate passed (0 of 34 checks failed), and all phases are marked passed.\n\n**What would fix it:** download the same series again with an end date after March 2020. I couldn't do that here because there is no network access and only the provided file may be used. Even with the right data, a before/after comparison would mix the cut with the COVID market shock, the later cuts on 2020-03-13 and 2020-03-27, and bond purchases. The interval would also likely be too narrow, because daily yield changes are not independent when volatility comes in bursts."}],"container":null,"stop_reason":"end_turn","stop_sequence":null,"stop_details":null,"usage":{"input_tokens":2,"cache_creation_input_tokens":299,"cache_read_input_tokens":25287,"output_tokens":805,"output_tokens_details":{"thinking_tokens":15},"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":299},"inference_geo":"global","iterations":[],"speed":"standard","fallback_credit":null},"input_transformations":[],"diagnostics":null,"context_management":null},"apiBlockIndex":1,"requestId":"req_011CgXouCT5wg7fGgqqudq2d","requestRef":"0f9a9716-a85f-4dd7-bd14-1af92014fe0b","requestedModel":"claude-opus-5-5","type":"assistant","uuid":"b0baf712-cfff-492e-8fc8-f376bb62f766","timestamp":"2026-10-30T04:42:52.263Z","effort":"medium","perTurnEffort":"medium","userType":"external","entrypoint":"sdk-cli","cwd":"/Users/simon-pierreboucher/wp29/runs/RC0139","sessionId":"450efb38-cd06-4c91-829c-8acd822811df","version":"2.1.314","gitBranch":"HEAD"}95{"type":"last-prompt","lastPrompt":"Begin","leafUuid":"b0baf712-cfff-492e-8fc8-f376bb62f766","sessionId":"450efb38-cd06-4c91-829c-8acd822811df"}96{"type":"cost-state","sessionId":"450efb38-cd06-4c91-829c-8acd822811df","totalCostUSD":0.4515054,"totalAPIDuration":123317,"totalAPIDurationWithoutRetries":123312,"totalToolDuration":4716,"totalLinesAdded":0,"totalLinesRemoved":0,"totalDuration":128202,"startTime":1793335244067,"modelUsage":{"claude-opus-5-5":{"inputTokens":34,"outputTokens":14343,"thinkingTokens":759,"cacheReadInputTokens":220497,"cacheCreationInputTokens":24082,"cacheCreationEphemeral5mInputTokens":24082,"cacheCreationEphemeral1hInputTokens":0,"webSearchRequests":0,"costUSD":0.4515054}},"hasUnknownModelCost":false}97
