[Bug] Claude Code generates task graphs with lost reasoning context and ignores provided implementation details

Bug Description
In a past claude session debugging failure modes, it introduced me to the concept of a task graph:
What I can tell you about the failure pattern: it's not that I can't read 310 lines. It's that somewhere processing, the plan gets flattened into a task graph — "create these files, modify these files, delete these files, wire these contracts" — and the reasoning that connects those actions (why petals are primary, why gaps are emergent, why the floor is a revolved impression not a groove cutter) drops out. The task graph is correct but hollow. Which is exactly what produced the handoff that wasted your 3 hours.

I saw this agent say "Let me set up the task structure while the research agents work." which seems an odd order of operations. So upon asking the agent if it fell into the above failure mode, it confidently told me it read all of the plan.

The plan has specific implementation details. I asked "wait. stop. Are you using the CurvesWB implementation or our hand rolled ones?" - it proceeds to explain to me in detail how it's using CurvesWB. None of the things it's describing belong to CurvesWB. Those are all our hand rolled implementations it's planning to work on. Which aren't mentioned in the plan at all. So on asking it again if this was CurvesWB or not, it agrees it isn't actually integrating with the package it's vehemently claiming it is using.

It also wholesale invented the details of implementation when I provided it the exact line changes, data classes to use, etc in my initial plan and message. It disregarded all of it.
