…SO times (tddworks#540) From the review on tddworks#540: - DeviceLabel counts 1–40 in UTF-16 units, as the server's readLabel does, so a label with emoji isn't refused as 400 badLabel. - ServerTime reads only ISO 8601, the server's toISOString(); SQLite and Unix-time forms are refused rather than guessed. - MemberDevices owns which device joined, the first week and what was added since a device; Device.removed(by:at:) marks a removal. - Joining's steps carry their key, interval and summary, so the parallel optionals are gone; the public Joining is unchanged. - Device, DeviceRef and PendingDevice labels are DeviceLabel; removedBy and LeaderboardError.removed(by:) keep the DeviceRef. - design.md: §2 tree and a MemberDevices section, §2a's flow and joining states, §4 owners, §5 times and labels, §7 MachineIdentity.

…cted wait (tddworks#540) The rest of the tddworks#540 review's point 3 and its small things: - DeviceKey names a device by the key it signs with: Device, DeviceRef, MemberDevices and shownDevices use it. Text only on the wire (the LeaderboardAPI calls, the JSON) and in settings.json, which is unchanged. - LeaderboardMembership takes the wait between a new device's asks as `sleep`, like `now`; a test pins that it waits the server's interval. - design.md: shownDevices as Set<DeviceKey>; DeviceKey in §7's pieces.

Joining and its JoiningState leave the membership. - design.md: the request in §2's tree and its own section, §2a's stages, §3's tells, §4's owner, §7's pieces; CANONICAL_MODEL's Leaderboard row.

LeaderboardMembership.join(through:sharing:) checks its own rules, then tells it, instead of reading `approval` and setting `markJoined()`. - DeviceRequest's wait defaults to Task.sleep; the membership no longer carries a `sleep` it never used. - DeviceRequestTests builds the request directly: the wait, the member, expiry, decline and the hand-over. - design.md: DeviceRequest's laws and tells.

It replaces offersDeletingDays(whenRemoving:) and the deletingDays flag. - MemberDevices' rules (joined, isInFirstWeek, added(since:), removing, adding, device(withKey:)) and Device.removed(by:at:) are internal: a view lists the devices and asks the membership, never the rules. - design.md: §2's tells and answers, §3's tells, §4's owner.

A new reference, implement-feature/references/domain-shape.md, shared by implement-feature, improvement and fix-bug: start from the root problem (the facts, the concepts they force), check every touched type against the shape rules (one aggregate per lifecycle, each changing only its own state, abilities not rules, choices not flags, no parallel optionals, pointable types, direct tests, exact boundaries), refine in scope, draw now beside proposed. Each rule carries the #540 example it came from. AGENTS.md's step 2 asks it of every change; each skill gets a step and a checklist line. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

domain-shape.md asked eleven shape rules, every example from #540. It now asks five questions for a domain easy to understand — would the person say it, does the thing decide about itself, can you see every state, is it as small as it can be, is what differs data — with #536's chart as the worked example. The skills and AGENTS.md point to the questions. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Merging as it stands: the shared wait for |
DeviceRequest owns "it asks at the server's pace". A second waitForApproval() while one ran (a view's task run again) started a second loop and doubled the asks (CodeRabbit on #540). Now the request keeps one wait, shared by whoever waits, and once approved answers the member without asking again, so a caller just after approval doesn't get notJoined.

…two never poll at once (tddworks#540) A second waitForApproval(), as a view's .task that runs again starts one, made a second loop beside the first, and both asked /me at the server's interval (CodeRabbit). Each wait now takes a number; after every ask and every sleep, a wait that is no longer the latest ends in CancellationError without asking again. A test holds the first wait in its sleep, begins a second, and checks the server is asked 3 times, not 4.

Why
Part of #507: devices, slice 13 of the leaderboard design (§2a, §8), next in the order posted there. People code on more than one machine, and the server has known devices since slice 11 (
tddworks/claudebar-server#1). The app still can't add a second Mac to a member, see that one was added, or remove one. This PR builds that in the app's domain. The surfaces are slice 15, from a mockup first, so nothing changes on screen yet.Design
The leaderboard design §2a and §8 slice 13. The doc records what is built, and, from the review, the shape the device types took:
MemberDevicesandDeviceRequestin the tree, each with its section.toISOString(), and a label's 1–40 characters are UTF-16 units.MachineIdentityin the diagram, and the homes table.Choices the design left open:
Internal/macOS/(MacModel), "Mac" included, because only a platform folder names a platform (MODULAR_DESIGN §3 rule 7).MachineIdentity.modelanswers aDeviceLabel.DeviceLabelkeeps it, or what the person typed, to the server's 1–40 characters without control characters, counted in UTF-16 units as the server'sreadLabelcounts them.GET /mewith its key and noX-Member. It has no member yet, andX-Memberisn't part of the signed string (§5)./me./medoesn't say which device joined. The member's earliest device is the one that joined, since every other one was added later, so that one is never held to a first week.shownDeviceskeeps the shown ones insettings.json(§2a: "the device's own, never sent").DeviceRequest. If the app quits then, the server has the device under a key this Mac no longer holds. The member sees it as added and can remove it.DeviceRequest(from the review). A Mac is either asking to be added or a member's device, never both, asdevice_requestsanddevicesare on the server. The request owns the code, the unsaved key, the wait at the server's interval, expiry anddecline(); the membership only starts one and joins through it./meare what the server writes,toISOString(): UTC, milliseconds,Z. The app reads that, and without the milliseconds, and refuses any other form rather than guess. It writes a device's times back the same way, so Settings' Export… file reads back as the same instants;JSONEncoder's own form counts seconds from 2001 and read back 31 years early.What changed
