CallJoining (issue #1261) — the handshake, before the roster arrives. Says nothing about who is present, because nothing is known yet: the other two stages both claimed an empty room here, and others were already in the call.

CallInvitePrompt (issue #742's G3) — the "Meet now" host's post-start nudge to invite people, shown once and dismissible. Shares demoJoinPolicy with the People-panel controls below, so its hint (F1) tracks the same picker: set the policy to anything but "Colleagues in, others wait in the lobby" to see it.

CallGallery — responsive fit at a low-res floor (issue: 4-tile call clipped off-screen on a low-res Windows display). Boxes below match the gallery's available canvas at 1280x720 and 1024x600 after the call chrome (top bar, controls, margins) — every tile must stay fully inside the border, at any count.

CallGallery — pagination + recent-speaker promotion + tiny-window collapse (issue #528, scale Phase 2). One participant (#17) is speaking off-page: the shared feed-priority ranking promotes them onto whichever page you are looking at, taking the LAST slot so the top rows hold. Everyone beyond the page shows as an initials card in the overflow row. Page-size options are Teams' rungs minus 49 (our product target tops out at 20-25 tiles). The DEFAULT is per device class (issue #537, from the Phase 1 knee measurement): 10 tiles low-end — the machine has 8 hardware decoders and the 9th stream is the first to fall to software — and 20 high-end. 25 stays offered, but nothing defaults there.

Tiny-window collapse — the same gallery in a 240x170 box (a call parked in a screen corner): tiles drop to face-icon initials cards, packed square instead of letterboxed, and the visible page's wanted set goes empty so nothing decodes. The pager stays, since it is the only way to reach the rest of the room.

CallReactionPicker (in-call reactions) — three groups: one-shot reactions, Yes/No, and the persistent Raise hand toggle. Click Raise hand to see its Raised state; close and reopen and it stays. Escape and an outside click close it.

CallSidePanel + CallPeoplePanel (docked, resizable; click a top-bar button above to open). People also carries the Invite affordance (issue #681's in-call invite) and the Meeting options gear (issue #742's G2, MeetingOptions) via CallSidePanel's headerAction slot — click the gear to swap in the "Who can join" picker, or the plus to swap in CallInviteBar above the roster. Set the policy to anything but "Colleagues in, others wait in the lobby" to see CallInviteBar's F1 hint on Copy join link. Typing "taken@example.com" demonstrates the already-invited failure path; "cancelled@example.com" demonstrates the DIFFERENT cancelled-meeting one (#742 review round 2); anything else succeeds. Above both sits CallLobbyQueue — the host's admit/deny queue for a meeting's lobby (issue #681), which renders nothing once the queue empties; that is also when the People button loses its dot. Hovering a removable row reveals Remove (issue #674 step 4) — a moderator's eject, behind an inline two-step confirm rather than a dialog over the call stage.

Call stage

CallKnockCard — the same door, announced OVER the call instead of inside the People panel (issue #1706), for the host who never opens that panel. Its clock lives in the app (hws-web's knock-alerts.ts): 15s per showing, one repeat a minute later, then only the People button's dot. Rows stack oldest-first and Admit all appears once there is a crowd. Drag the browser narrow: the buttons wrap under the name rather than the name truncating.

CallLobbyWaitingCount — the same door seen by a participant who cannot admit (issue #1708). It sits where CallLobbyQueue sits, at the top of the People panel, but says only how many people are waiting: no names, no avatars, no Admit/Deny, and nothing to fire a sound or a toast from. It is driven by the same waiters as the card above, so admitting somebody there counts down here; it renders nothing at all once the lobby empties.
