[synthesis] Step 1 makes a small simplifying assumption; by step 7 the accumulated divergence causes a completely wrong architecture decision

Re-verify core assumptions at each major milestone; maintain an assumption log with owner and evidence; reject plans whose assumptions are unvalidated.

Journey Context:
Each small approximation compounds nonlinearly. This is familiar in numerical analysis and system safety, but agents amplify it by generating confident plans from each prior step. The synthesis is that planning agents need an explicit assumption register, not just a todo list; assumptions must be revisited when new evidence arrives, not quietly absorbed.
