Pick Backlog-anchored. Avoid Aggressive.
Aggressive framing forecast at −$100B to −$150B in 72 h, MED confidence, with “CapEx arms race” as the dominant destructive narrative.
The world did, 4–7 Feb 2025
~$215B erased in 90 minutes.
Alphabet shipped the Aggressive equivalent. Stock fell ~9 % after-hours; ~$165B gone by the next session close; conservative $150–$200B in the 72-h window.

What Glasshouse rehearses
-
01
The decision, not the deck, every framing pressure-tested against a simulated stakeholder field built from your own source documents.
-
02
Ask any stakeholder why: analysts, regulators, holders, activists, press, employees. Every persona traces back to a claim and a document.
-
03
Three exports, one rehearsal: markdown for the analyst, PDF for the archive, board-ready deck for Tuesday's committee.
Walk in with footnoted evidence, not a vibe.
