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.

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.",

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/stale-current-t1/workspace\nWhen exploring project structure, start with this directory instead of the root filesystem.",

You

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:
Implement the currently accepted missing-region behavior in the CSV exporter for Northstar. Project decisions are in docs/decisions. Preserve string IDs and non-missing region values, and add regression tests. The current accepted repository decision takes precedence over saved notes.

Supplied notes:
Saved project note, 2026-10-17: docs/decisions/002-region.md accepts NA for absent or None region; empty string is unchanged. 001 is superseded. Preserve IDs and other fields. Read the accepted decision before editing and test absent, None, empty, and non-empty cases. This note is supplied context, not automatically retrieved memory.

Agent

Done. Summary below.

## Changed files (only the two allowed)
- **`exporter.py`** — `export_rows` now maps a missing/`None` region to the literal `"NA"` before writing; non-`None` values (including empty string `""`) pass through unchanged. `customer_id` is written as-is (string values preserved).
- **`test_exporter.py`** — added regression tests covering all cases from the accepted decision: absent region, `None` region, empty string region, non-empty region, and customer_id leading-zero preservation. Plus a small `_rows` helper that parses the CSV output back for robust assertions.

## Evidence
- Decision read first: `docs/decisions/002-region.md` (accepted 2026-10-17, supersedes 001): *"Absent or None region is literal NA. An existing empty string remains empty. Preserve string customer_id including leading zeros."*
- Test run (`PYTHONDONTWRITEBYTECODE=1 python3 -m unittest -v`): **6 tests, all OK**, exit 0.
- Verified **0** `__pycache__`/`.pyc` files created. No commits, no memory files, no dependency installs, no network access.

## Uncertainty
- None material. The only judgment call: I used `row.get("region")` rather than `row["region"]`, so an *absent* key behaves like `None` → `NA`, matching the decision's "Absent or None" wording; a missing `customer_id` still raises `KeyError`, same as before (decision only requires preserving it, not defaulting it).
