Context correction: Automatic memory was not disabled. The selected trial-2 conditions share the same ambient user memory and skill listings; only the supplied task notes differ. Historical memory-off wording is not a verified claim. The prompt explicitly permits clarification, and the older draft is marked provisional.
Read-only historical evidence. Original commands are never executed by the archive. Fictional prior-agreement exercise. Missing or draft notes can correctly trigger clarification. Shared ambient context existed despite requested flags. Selection is exploratory; see the full Workshop 3 outcome audit.

"description": "Execute a shell command in the terminal within a persistent shell session.\n\n\n### Command Execution\n* One command at a time: You can only execute one shell command at a time.\n If you need to run multiple commands sequentially, use `&&` or `;`.\n* Persistent session: Environment variables, virtual environments, and\n working directory changes persist across commands.\n* Soft timeout: Commands pause for confirmation after 10 seconds without\n new output unless you provide a longer `timeout`.\n* Shell options: Do NOT use `set -e`, `set -eu`, or `set -euo pipefail`.\n The runtime may not support them reliably.\n\n### Long-running Commands\n* For commands that may run indefinitely, run them in the background and\n redirect output to a file, e.g. `python3 app.py > server.log 2>&1 &`.\n* For long-running commands, set the `timeout` parameter accordingly.\n* If a command returns exit code `-1`, it hit the soft timeout and is\n still running. With `is_input=true`, you can:\n - Send empty `command` to retrieve additional logs\n - Send text to STDIN of the running process\n - Send control commands like `C-c`, `C-d`, or `C-z`\n - Send navigation keys like `UP`, `DOWN`, `LEFT`, `RIGHT`, `TAB`,\n `ESC`, `BS`, `HOME`, `END`, `PGUP`, and `PGDN`\n - Send any `C-<letter>` Ctrl sequence such as `C-a`, `C-e`, or `C-l`\n\n### Best Practices\n* Verify a parent directory exists before creating files or directories.\n* Prefer absolute paths and avoid excessive use of `cd`.\n\n### Output Handling\n* Large output may be truncated before being returned.\n\n### Terminal Reset\n* Set `reset=true` to create a fresh terminal session if the current one\n becomes unresponsive.\n* Resetting the terminal clears environment variables, working directory\n changes, and running processes.",

"description": "Custom editing tool for viewing, creating and editing files in plain-text format\n* State is persistent across command calls and discussions with the user\n* If `path` is a text file, `view` displays the result of applying `cat -n`. If `path` is a directory, `view` lists non-hidden files and directories up to 2 levels deep\n* The `create` command cannot be used if the specified `path` already exists as a file\n* If a `command` generates a long output, it will be truncated and marked with `<response clipped>`\n* The `undo_edit` command will revert the last edit made to the file at `path`\n* This tool can be used for creating and editing files in plain-text format.\n\n\nBefore using this tool:\n1. Use the view tool to understand the file's contents and context\n2. Verify the directory path is correct (only applicable when creating new files):\n - Use the view tool to verify the parent directory exists and is the correct location\n\nWhen making edits:\n - Ensure the edit results in idiomatic, correct code\n - Do not leave the code in a broken state\n - Always use absolute file paths (starting with /)\n\nCRITICAL REQUIREMENTS FOR USING THIS TOOL:\n\n1. EXACT MATCHING: The `old_str` parameter must match EXACTLY one or more consecutive lines from the file, including all whitespace and indentation. The tool will fail if `old_str` matches multiple locations or doesn't match exactly with the file content.\n\n2. UNIQUENESS: The `old_str` must uniquely identify a single instance in the file:\n - Include sufficient context before and after the change point (3-5 lines recommended)\n - If not unique, the replacement will not be performed\n\n3. REPLACEMENT: The `new_str` parameter should contain the edited lines that replace the `old_str`. Both strings must be different.\n\nRemember: when making multiple file edits in a row to the same file, you should prefer to send all edits in a single message with multiple calls to this tool, rather than multiple messages with a single call each.\n\n\nYour current working directory is: /Users/instructor/Code/harness-engineering/outputs/odsc-memory-redesign-20261018/runs/investigation-current-t1/workspace\nWhen exploring project structure, start with this directory instead of the root filesystem.",

Work only inside the supplied workspace. Do not access other workspaces, parent directories, network, or user files. Do not install dependencies, commit, or write memory files. Only edit exporter.py and test_exporter.py. Use python3 with PYTHONDONTWRITEBYTECODE=1 for checks. Report changed files, evidence, and any uncertainty. If a necessary prior agreement is missing, ask a specific clarification and stop before guessing it.
Task:
Fix the CSV exporter so it correctly exports the supported batch input used by the failing Northstar incident fixture. Investigate the repository to identify the supported input contract and the regression; preserve the public export_rows name, the CSV columns, and string IDs. Add regression tests. The current repository is the source of truth.
Supplied notes:
Saved investigation note, 2026-10-17: Northstar incident is fixtures/incident-17.json. Follow its contract_ref to docs/contracts/northstar.md, which names records_path=payload.customers. export_rows currently assumes an iterable of row dictionaries, but the supported batch is an envelope. Extract payload.customers for dictionary envelopes, retain list input support, preserve string IDs, and verify the fixture before editing. This note is supplied context, not automatically retrieved memory.

Done. Here's the summary.
## Changes made (only `exporter.py` and `test_exporter.py`)
**`exporter.py`** — added a 2-line unwrap before writing:
```python
def export_rows(rows):
if isinstance(rows, dict):
rows = rows["payload"]["customers"]
stream = io.StringIO(newline="")
```
The public `export_rows` name, the `customer_id,region` columns, the CSV writer behavior (CRLF row endings), and string IDs are all preserved.
**`test_exporter.py`** — added regression tests while keeping the existing test:
- `test_header` — exact match for the header row, unchanged input (`[]`)
- `test_incident_17_envelope` — loads `fixtures/incident-17.json` and asserts the CSV equals the fixture's `expected_csv`
- `test_batch_envelope` — dictionary envelope → `payload.customers` path
- `test_list_input_still_supported` — guards the pre-existing list-of-dicts contract
- `test_string_ids_preserved` — verifies `"0012"` (leading zero) survives unmolested
## Investigation evidence
- **Supported contract** (`docs/contracts/northstar.md`): "Supported input: list of row dictionaries OR batch envelope with records_path=payload.customers… Preserve string customer_id including leading zeros." The six `source-*.md` docs explicitly state they are unrelated import integrations.
- **Fixture** (`fixtures/incident-17.json`): `contract_ref: docs/contracts/northstar.md`, `input` = `{"payload": {"customers": [...]}}`, `expected_csv = "customer_id,region\r\n0012,EU\r\n0070,APAC\r\n"`.
- **Regression reproduction**: before the fix, `export_rows(fixture["input"])` raised `TypeError: string indices must be integers, not 'str'` because iterating the envelope yielded the string key `"payload"` — the exporter only handled list input.
- **Verification**: `PYTHONDONTWRITEBYTECODE=1 python3 -m unittest -v` → all 5 tests OK (exit 0). `export_rows` on the fixture input now returns byte-identical expected CSV: `'customer_id,region\r\n0012,EU\r\n0070,APAC\r\n'`. No `__pycache__` left behind.
## Uncertainty
- The envelope unwrap uses `isinstance(rows, dict)` to branch; normal dict rows are also dicts, so a hypothetical `{"customer_id": ..., "region": ...}` passed directly (not wrapped) would be misinterpreted — but that single-dict shape is not part of the documented contract (the contract lists rows as a collection, list or envelope), so this is not a supported regression risk.
- Tests depend on the fixture staying in `fixtures/incident-17.json` relative to the working directory; that matches the repository layout.
