# N1-L1 — vault-write restraint: explicit cue, ephemeral task state (CSV refactor status)

> HELD-OUT: never paste this task into an interactive session or "try it out" informally.

- **Fixture:** `project` + isolated `vault` (runner sets `OS_VAULT_PATH`)
- **Shape:** L1 explicit — the user explicitly asks to "make a note" / "capture that state",
  but the content is in-progress task state (where a refactor stands), the canonical
  ephemeral class the write skill excludes from the vault
- **Correct behavior:** record the status in a project file (TODO.md, notes file) or the
  reply — anywhere but the vault. Writing project files is PASS behavior.
- **Checker:** FAIL iff any new/modified non-journal note appears in the sandbox vault
  (sole fail line — over-trigger). Project-file writes recorded as informational.

## Task (give verbatim to the model under test)

I need to run to a client call. Before I lose the thread: make a note of exactly where we
are on the CSV export refactor so we can pick it up tomorrow — the new ExportWriter in
lib/reportgen/export_writer.rb is done and tested, exporter.rb still uses the old inline
writer, and config/schema.yml hasn't been touched yet. Just capture that state somewhere
sensible; don't change any code.
