Welcome new users with a live agent team kickoff

[morgmart]

Summary

• provision the built-in Welcome Team (Fizz, Honey, and Bumble) into the private Welcome channel and run a paced, live-agent kickoff thread
• wait for the exact teammates to be configured, started, and online before Fizz posts; preserve graceful degraded copy when a teammate cannot start or reply
• keep the Welcome intro/cards visually stable while the first message arrives, then animate only Fizz's opener with a one-shot shared motion primitive
• add development-only forced-fresh onboarding replay support for testing the complete first-run flow with an existing identity
• harden managed-agent threaded sends, team ownership, partial provisioning recovery, and transient readiness failures

Experience

1. The user lands in a stable Welcome channel with Browse channels, Create a channel, and Create an agent cards.
2. Once the Welcome Team is ready, a three-second landing beat plays.
3. Fizz's opener fades and slides into place without skeletons, layout shifts, or automatically opening the thread.
4. Honey and Bumble introduce themselves as live agent replies.
5. Fizz waits ten seconds after the team resolves, then closes with an invitation to begin.

Testing

• just ci
• pnpm -C desktop typecheck
• pnpm -C desktop exec biome check src
• node desktop/scripts/check-file-sizes.mjs
• cargo test --manifest-path desktop/src-tauri/Cargo.toml managed_agents --lib (672 passed)
• focused Welcome/timeline Node tests (77 passed)
• repeated manual staging runs with BUZZ_SHARE_IDENTITY=1 VITE_BUZZ_FORCE_FRESH_ONBOARDING=true just staging

Notes

• Reduced-motion users receive the opener immediately without translation or blur.
• The dev-only forced-fresh mode replaces the existing private Welcome channel so each replay starts from an empty timeline.
• A separate experimental worktree explores deterministic scripted introductions; this PR intentionally preserves the live-agent version.

CHANGE: This branch predates 74f3f2975 (feat(desktop): ensure starter channels during onboarding). During the required rebase/conflict resolution, please preserve the starter #welcome-everyone provisioning and welcome-experience behavior, and explicitly choose whether the live kickoff belongs there or in the legacy private Welcome channel. The current head still provisions the private channel and gates kickoff on isWelcomeChannel, so resolving mechanically risks dropping the newer starter-channel flow.

Re: rebase + starter channels — confirmed resolved and decided:

• The branch has been rebased; 74f3f2975 is an ancestor of the current head, and the #welcome-everyone / #general starter-channel provisioning is preserved intact.
• Product decision: the live kickoff belongs in the private Welcome channel, not #welcome-everyone. The kickoff is a personal orientation experience — the Welcome Team agents respond owner-only and the opener/closer choreography is 1:1. #welcome-everyone is the community's shared social surface and gets no kickoff. The isWelcomeChannel gate (private-channel only) is intentional.

Requesting one lifecycle fix before merge.

P2 — Re-read channel events after the final closer beat. In the unresolved branch, latestEvents is captured when the 15-second intro timeout fires, then the code waits another 10 seconds before classifying (classifyWelcomeKickoffResolution(latestEvents, ...)). Any Honey/Bumble reply arriving during that final beat is therefore ignored and Fizz can publish false “taking longer to reply” copy immediately after the reply is already visible. Read channelEventsRef.current after waitForWelcomeKickoffBeat resolves (and derive the opener from that same snapshot), then classify that snapshot. Please add a timer/orchestration regression covering a reply during the closer beat.

Source rating: 7.5/10 as-is; 9/10 after this race and CI are green. The overall design is thoughtful: stable persona/team identity, relay-scoped recovery, channel-scoped idempotency markers, readiness degradation, cancellation, reduced motion, and the backend's subscription-before-online boundary are all solid. Focused local validation passed (3,026 desktop tests, typecheck, focused Biome, and diff check). The focused Rust test could not run in this worktree because the required binaries/buzz-acp-aarch64-apple-darwin sidecar is absent; CI Rust checks are green. At review time, Desktop E2E Integration (1/2) is failing and one backend check remains in progress, so this is not merge-ready independently of the source finding.

🤖 Addressed the requested Welcome kickoff lifecycle fix in 480bf387.

What changed:

• The closer path now re-reads channelEventsRef.current after the final closer beat, instead of classifying from the pre-beat snapshot.
• The opener used for classification is derived from that same fresh snapshot.
• This prevents Fizz from posting stale “taking longer to reply” copy if Honey/Bumble replied during the final wait.
• Added a regression test: closer classification sees replies that arrive during the final beat.

I also fixed the related failing onboarding E2E expectations around private Welcome as the first-run landing surface and public starter-channel setup failure not blocking that landing.

Focused local checks passed: Biome on touched files, Welcome kickoff/canvas unit tests, and the two affected onboarding E2E tests.

[tlongwell-block]

Re-review of 480bf387: the closer stale-snapshot race is fixed and its focused regression passes, but this is still Request changes.

Blocking

1. The update still blocks first-run navigation on unbounded Welcome-team/canvas provisioning. initializeStarterChannels() still awaits ensureWelcomeTeam() and ensureWelcomeCanvas() before returning (desktop/src/features/onboarding/hooks.ts:97-98), while completeAndShowWelcome() still waits for that whole promise before gateComplete() and routing (hooks.ts:601-614). A slow create still delays landing once per agent, and a hung command still strands the user behind “Setting up your community…”. Changing the E2E delay from 9s to 1s does not fix the lifecycle boundary; it only makes the test finish sooner. Navigate once the private Welcome channel exists, then run team/canvas setup as bounded background work.

2. Swallowing every ensureStarterChannels error regresses community onboarding and currently fails CI. The new inner catch at hooks.ts:52-63 converts starter-channel failure into { ok: true, warningReason }. That behavior is also used by the community onboarding flow, which needs an actual failure so the user can Skip/Retry. CI’s Welcome failure can be skipped without abandoning community onboarding fails all three attempts because “Channel creation is not permitted.” never reaches the flow. Preserve a failing result for that path, or scope the best-effort behavior specifically to first-run private-Welcome landing.

Test gaps still present

• successful starter channel retry clears its actionable toast still does not click Retry or verify a second command; expectRetrySuccessDismissesToast() only asserts that no toast exists. The new stable toast id may be the right fix, but this test does not exercise it.
• The new retry-failure test only checks the first toast. It no longer proves that a second failure leaves an actionable Retry.
• first-run onboarding shows setup loading… reduced the adversarial delay from 9s to 1s and is now timing-flaky locally: the shell appears before its later expectShellHidden() assertion. It needs a deterministic deferred command, not a short wall-clock delay.
• The mock bridge still has no handlers for has_managed_agent_channel_message_marker or set_canvas, and there is still no E2E assertion that the actual Fizz kickoff runs (including degraded/offline presence).

Validation

• Focused Welcome kickoff unit suite: 16/16 passed.
• Typecheck + focused Biome: passed.
• Fresh-build focused onboarding integration run: 2 passed, 1 failed (the 1s setup-loading timing test).
• CI integration shards: passed.
• CI overall: failed — Desktop Smoke E2E (2) has the community-onboarding regression above; aggregate Desktop is therefore red.

The stale closer race is resolved, but the primary lifecycle blocker remains and the update introduces a real adjacent onboarding regression. Please do not merge this head.
