 3. The campaign screen exposes the current summary, important memories, and active goals. The dashboard shows 30-day tokens, cost, latency, and the current daily request allowance.
 4. Campaign owners may correct HP, inventory, or statuses through the audited character-state API; the reason and before/after values are retained in `audit_entries`.
 5. `pnpm test` includes twenty long-memory regression scenarios. `pnpm e2e:full-party` verifies the hosted two-player/AI-companion flow end to end.

+## Weeks 9–10 closed-alpha flow
+
+1. A dismissible field guide on the dashboard takes a new tester from world creation through confirmation, invitations, and their first ready action. Its progress follows real drafts and campaigns and is stored per account on the device.
+2. Round controls remain available in a compact panel on tablet and phone layouts. Owners can create and copy invitations, configure AI takeover, continue without a missing player, and retry a failed round without switching to desktop.
+3. The dashboard reports 30-day round failures, mean and p95 queue-to-resolution latency, true cost per AI job (including paid retries), and the mean planning-context size. Recent failures link directly back to their private campaign; only campaign owners receive round operations data.
+4. Before inviting testers, run `pnpm alpha:verify`. It executes all unit and regression tests, strict workspace typechecking, and the production build. On a configured alpha environment, also run `pnpm e2e:full-party` while `pnpm dev:all` is active to verify the real two-account invitation and round path.
+5. Team and invited-user checks must cover narrow phone, tablet, and desktop widths; a normal all-ready round; owner continuation with an absent player; failed-round retry; and a return after at least three resolved rounds to confirm durable memory. Treat inaccessible round controls, private-data exposure, duplicate narration, partial state after failure, or an incorrect server-owned roll as release-blocking.
