Weekly client update in five lines

Write my weekly client update.

The project and the client: <what, for whom, how formal>
What I did this week: <list, messy is fine>
What's planned for next week: <list>
What's blocked or at risk, and why: <list>
Decisions or inputs I need from them, and by when: <list>
Anything that changed in scope, timeline or cost: <or "nothing">

Write the update, under 150 words:
- One line of status: on track / slightly behind / at risk, and one sentence why.
- Done this week: 3–5 bullets, outcomes not activities ("the booking flow now handles cancellations", not "worked on booking flow").
- Next week: 2–3 bullets.
- Blocked / needs you: each item with what I need and the date I need it by.
- Changes: one line, or "No changes to scope, timeline or cost."

Rules: no filler, no apologies for a slow week, no jargon the client wouldn't use. Plain sign-off. Then give me a subject line under 8 words with the project name and the date.
