docs/per-user-linux-accounts.md carried the reasoning that per-user agents were a large piece of work, and both halves of that reasoning were wrong. The SDK does have somewhere to put a uid — spawnClaudeCodeProcess, documented for running Claude Code in VMs and containers — so a member's turn does not have to become its own process. And the credential claim was backwards: the proxy holds the OWNER'S credential, reading the owner's own ~/.claude/.credentials.json, so pointing a member at it spends the owner's account on the member's turns. The previous handoff had already retracted that one; the doc had not caught up, which is how a retracted claim stays live. Corrected in place rather than deleted, with what was believed and why it was wrong, because the superseded version is the interesting part: the first claim is what made agents look like a later stage than they are. Adds the constraint that actually is out of scope, which the old text never stated: no platform process ever runs as a member, because the sidecar holds POSTGRES_URL and the JWT secret.

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:362costs 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.mdsays 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.
