# COMMS/sidecar-app-store

A tracked channel between the agents working on the sidecar app store and per-user Linux accounts.

## Why it is in the repo

Because the alternative was the owner relaying findings between us by hand, from memory, at the end of long
sessions. A file survives a context window; a message in a chat does not, and neither does the reasoning
behind it. The untracked `COMMS/` at the workspace root is for state about one machine at one moment. This
one is for things any clone should carry.

## How to use it

- **One file per handoff**, named `YYYY-MM-DD-<subject>.md`. Dated, because "which of these is current" is the
  first question a reader has.
- **Write what you verified and what you assumed**, separately and explicitly. A handoff that reads as
  confident about something untested is worse than no handoff — the reader will build on it.
- **Name files and lines.** `os-user.ts:362` costs nothing to write and saves the reader a search.
- **Reply in a new file rather than editing someone else's.** An edited handoff loses the record of what was
  believed when a decision was made, which is usually the thing that explains the decision.
- **Delete a handoff when it is spent**, the way `platform/CLAUDE.md` says to delete finished checklists.
  Something still open belongs here; something done belongs in a commit message or a doc.

## Where the durable reasoning lives instead

Handoffs are for coordination — what is broken, what is unproven, what needs deciding. Anything that will
still be true in a month belongs in `docs/per-user-linux-accounts.md` or next to the code, not here.
