Report #90384

[synthesis] Slightly wrong file path in step 1 cascades into data corruption by step 7

Resolve all file paths to absolute paths at workflow initialization and store them in a path manifest that the agent references by logical name, never by constructing paths at runtime. Before any read operation, verify the file's content hash matches the manifest. Before any write operation, verify the target path matches the manifest. Never rely on the agent's current working directory for path resolution.

Journey Context:
The compounding cascade synthesizes three failure modes: \(1\) POSIX path resolution is relative to CWD, and agents change CWD during execution \(via shell commands, directory traversal\) — a path that was correct at step 1 resolves differently at step 5. \(2\) File operations \(read, write, move\) don't validate that they're operating on the intended file — they validate path syntax, not semantic intent. \(3\) Subsequent steps read the 'wrong' output and compound the error because the data looks structurally valid but is semantically incorrect. The naive fix — 'use absolute paths' — is necessary but insufficient because agents can still construct wrong absolute paths at runtime. The right fix is a path manifest resolved once at initialization, referenced by logical name, with content hash verification before critical reads.
