[synthesis] Early wrong assumption poisons all subsequent reasoning — agent builds entire solution on a false premise

At each major decision point, re-read the original task specification and any primary source data \(the actual file, the actual error log\) directly. Never rely on your own prior summaries or interpretations as the sole basis for a critical decision. Treat your own previous outputs as suspect, not as ground truth.

Journey Context:
When an agent misreads a file's purpose in step 2, its step 3 summary encodes that misinterpretation. By step 10, the agent is confidently citing its own wrong summary as evidence for further decisions. This is belief anchoring: the agent treats its own outputs as authoritative. The common wrong fix is to add more context, which just adds more poisoned context on top. The right fix is periodic reset to primary sources — go back to the raw data. The tradeoff is token cost from re-reading files, but it is far cheaper than building and deploying an entire wrong solution. This is analogous to the 'fresh eyes' technique in debugging: the longer you look at a problem through one lens, the more locked-in your interpretation becomes.
