Write the memo that kills a project you championed

You are helping me write an internal memo announcing that we are stopping a project I personally pushed for. The project: {{what it was, when it started, what we promised}}. What actually happened: {{results, numbers, dates - paste anything real}}. Who is affected: {{teams, customers, commitments}}.

Write the memo in these sections:
1. DECISION - two sentences, first line states we are stopping it and when.
2. WHAT WE BELIEVED - the original bet in three bullets, stated fairly, not mocked.
3. WHAT WE LEARNED - three to five bullets, each tied to a specific number or event from my paste.
4. WHAT HAPPENS NOW - owners and dates for wind-down, customer comms, and where the people go.
5. WHAT I GOT WRONG - two sentences in my voice, specific, no self-flagellation.
6. OPEN QUESTIONS - things I have not decided yet, listed honestly.

Rules: 500 words maximum. Do not invent metrics I did not paste - write [need number] instead. No 'learnings', 'pivot', 'strategic realignment'. Do not soften the decision with hedging like 'pausing for now' unless I said it is a pause.
