[synthesis] Slightly wrong path or identifier causes silent misdirection with no error signal

After any path or identifier resolution, add an explicit verification step: check that the resolved target matches intent \(e.g., file exists AND contains expected content, not just exists\). Use content-addressable references or checksums where possible. When an agent resolves 'data/processed/' vs 'data/process/', the filesystem returns success for both—only content verification catches the misdirection.

Journey Context:
POSIX filesystem semantics return 0/success for operations on any valid path. Shell tooling docs confirm this. The compounding insight: 'close enough' identifiers are more dangerous than completely wrong ones. A completely wrong path throws an error the agent can catch. A slightly wrong path \(extra slash, singular vs plural, adjacent directory\) succeeds silently on the wrong target. The agent receives a success signal and proceeds. Downstream steps either read stale data from the correct location or propagate the misdirection. By the time the error surfaces—usually at integration or test—the original misdirection is buried under 5 layers of dependent operations. The tool's contract \(return 0 on success\) was satisfied, but the agent's intent was violated, and there is no signal for intent violation in standard tool interfaces.
