 ## Recently shipped
 
+- **2026-05-06 — `feat/self-serve-signup-phase-2`** Phase 2 frontend cutover code (Tasks 27–44 of the plan, 18 commits). Backend remainders + frontend billing foundation + auth surfaces (OAuth + accept-invite + verify-email) + welcome wizard + dashboard redesign (TrialPill, NextStepCard, unified checklist) + public surfaces (`/pricing`, `/contact-sales`) + beta-signup deprecation. Phase O (Stripe live setup, internal validation, flag flip) is operational and pending. Single alembic head `c6cbfc534fad` (no new migrations).
 - **2026-05-02 — PR #159** In-product User Guides rewrite. Merged into `main`. Replaced 15 feature-dump guides with 43 problem-oriented Diátaxis how-tos grouped under 10 categories. Dropped Maintenance Flows / AI Assistant / Flow Assist Sparkles (UI no longer exists). Renamed Step Library → Solutions Library. Authored 14 net-new how-tos for FlowPilot-era surfaces (tasklane keyboard flow, what-we-know, resolve, escalate, record-fix-outcome, post-docs-to-ticket, share-update, pause-and-leave, build-script-from-scratch, open-suggested-flow, pin-a-flow, invite-teammate, etc.). Schema additions: `category`, optional `relatedSlugs`; hub renders category sections; detail page renders related-guides footer. Fixed rendering bug where `**bold**` in `step.tip` rendered literally. Killed misleading "N sections" subtitle on guide cards. Browser-verified against engineer + owner login (sidebar labels, account sub-pages, pilot-screen header buttons, Tasks panel, integration form). Two unverified items intentionally deferred: change-teammate-role (requires non-owner test member to inspect role-change control) and detailed Resolve / Escalate modal contents (Resolve gated by 6 pending tasks in test data). tsc and Vite build clean.
 - **2026-05-01 — PR #158** Session-screen UX impeccable pass + tasklane keyboard flow. Merged into `main` as `5e10005`.
   - **Impeccable pass** (5 sub-passes — distill / quieter / layout / typeset / polish): score 24/40 → 33/40. Removed the duplicate "Suggested checks" chip strip; added an inline `Next steps · N pending in Tasks` cue above the latest action-bearing AI bubble; consolidated the desktop session header to Resolve + Escalate + ⋯ kebab (Context / New Ticket / Update Ticket / Pause now under the kebab, mobile kebab gained Context + New Ticket parity); centered the messages column to `max-w-3xl` to match the composer; bubbles dropped to `rounded-xl`. Decoration sweep: dropped 3px side stripes (TaskLane done states, all 6 ProposalBanner modes, WhatWeKnowItem rows), gradient backgrounds (WhatWeKnow + every banner), accent borderTop on TaskLane header, backdrop-blur on handoff overlay, animate-pulse-amber ring in VerifyingBanner, bordered avatar boxes in banners. Type sweep: 14 distinct sizes → 5-step scale (10/11/12/13/14px). Icon disambiguation: `MessageCircleQuestion` split into `Pencil` (Answer CTA) + `HelpCircle` (per-check explainer). Dead `font-sans` audit (12 sites) and double `text-xs` cleanups.
