[frontier] Agent overcorrects or undercorrects on constraints it partially remembers

When re-injecting constraints, always include a concrete example of correct AND incorrect application. Ghost constraints arise when the agent remembers 'there was a rule about X' but forgets the exact boundary, leading to either over-application \(refusing valid actions\) or under-application \(allowing violations\). Concrete examples anchor the boundary.

Journey Context:
This is a subtle and under-diagnosed problem. The agent doesn't fully forget a constraint — it retains a 'ghost' of it. But the precise boundary is lost. Example: the constraint is 'use TypeScript for all new files.' After 40 turns, the agent remembers 'there's something about TypeScript' but starts applying it inconsistently — maybe converting existing JS files unnecessarily \(overcorrection\) or only applying it to some new files \(undercorrection\). Both are wrong but in opposite directions, making the bug hard to reproduce and diagnose. The fix is to pair every constraint with a concrete positive and negative example during re-injection: 'Use TypeScript for new files \(correct: new-file.ts; incorrect: converting existing.js to.ts; incorrect: creating new-file.js\).' This gives the model a pattern to match rather than an abstract rule to reinterpret.
