pastilhasandClaude Fable 5 6071ded175 todo: one file per item, grouped by theme, with a generated index
TODO.md had reached 1050 lines and 72 open items across 28 sections, read mostly
on a phone. It is now a directory: todo/<theme>/<item>.md, one card per file, with
frontmatter carrying id, status, created date and order, and the prose body copied
across verbatim. TODO.md becomes a generated index (bun run todo:index).

Dates: where an item's prose stated one it is used; otherwise its old section's;
otherwise 2026-08-20, floored at the day before the split rather than invented.
date_source records which.

Shaped for a two-way Kanban board, filed as todo/tooling — a card is a file, id is
the identity, frontmatter is the machine's half and the body is the owner's.

**Device invites, platform side** (`COMMS/OFFSCALE_INVITE_ENROLLMENT.md` §5, built 2026-08-05).
Authorize-new-device form, the one-time link with copy/share/QR, and the invite list with revoke —
`/_officer/enroll/invites` in `invites.ts`, `InvitesView`. **The records are not Officer's.** They
proxy to the server's Officer Companion, because the joining phone has to claim without an Officer
account and this sidecar is loopback-only behind our auth; the spec's own "an invite must work when
the platform is down" argument says the same. Officer stores no invite and no claim token.
**Live on all four servers since 2026-08-05.** The 401 that blocked it was a companion-side prefix
parse (a Headscale key prefix is a fixed 12 chars and may contain `-`; they split on the first one);
fixed upstream. Verified end to end against pastilhas-eu: create returns the
`officer-offscale://join#…` link, list shows the record, revoke flips it to `revoked`. The list
envelope is not in the spec, so `pickInvites` takes the body's array whatever it is keyed under.
Four gaps were sent back to the spec author: `keys.ts` has no
sub-day key TTL for the 5-minute claim key, "the sidecar must refuse plaintext" is unenforceable
behind nginx, `tailnet` is not a headscale concept and has to be recorded on the invite, and
`/api/v1/enroll/*` collides with headscale's own namespace.
