Report #102778

[synthesis] A near-correct file path in step 1 silently rewrites the wrong file by step 7

Treat every path as a computed value: derive it from an invariant anchor \(project root / cwd\) and re-resolve with os.path.abspath before each write; never concatenate paths across turns without re-anchoring.

Journey Context:
The common advice is 'verify before write', but verification fails because the agent remembers the intended path, not the actual one. The cascade happens when step 1 uses ./data/, step 3 changes cwd, step 5 writes to ../data/, and step 7's 'verify' reads the original and confirms it exists. Absolute re-anchoring breaks the decay chain; relative-path validation does not.
