Report #101332

[synthesis] Tool call reads the wrong file because relative-path resolution drifted between Read and Bash invocations

Resolve every filesystem target to an absolute path and re-read it after any directory change, symlink traversal, or external mutation before editing.

Journey Context:
Agents often mix Read/Edit with Bash commands, and Bash starts in a fresh shell while Read/Edit interpret relative paths from the project root. A slightly different cwd or a symlink can make step 1's correct-looking path point to a different inode by step 7. Common mistake is trusting the relative path from the first Read through a long session. Absolute paths are verbose but remove the silent-drift vector; re-reading after mutation closes the stale-handle gap.
