Report #104109

[synthesis] A near-correct file path chosen in step 1 corrupts seven steps later

Resolve every path through a canonical resolver and verify existence plus a checksum or content hash before writing; never let the LLM concatenate or guess paths.

Journey Context:
SWE-bench evaluations show agents frequently edit the wrong file, and path-normalization rules differ across OS and tool implementations. The failure is silent because the first write often succeeds by creating a new wrong file, so later reads return stale or empty data that the agent then reasons over. Canonical resolution plus a write-confirmation check breaks the chain before downstream steps accumulate.
