Report #43708

[synthesis] Agent creates a file at a slightly wrong path, then subsequent steps create MORE files at the wrong path, establishing a parallel wrong directory structure

After any file creation, immediately verify the path with \`realpath\` or equivalent. Use path constants defined once and referenced everywhere. Implement a 'path manifest' that maps logical names to absolute paths, and validate all paths against it before writes.

Journey Context:
Step 1: Agent intends to write to \`/src/utils/helpers.py\` but writes to \`/src/util/helpers.py\` \(missing 's'\). Step 2: Agent reads from the correct path, finds nothing, and creates \`/src/utils/helpers.py\` \(correct\). Now both exist. Step 3: Agent imports from \`util.helpers\` \(wrong\) because that's what it created first. Step 4: Another agent references \`utils.helpers\` \(correct\). The codebase now has two divergent modules. The compounding is severe because each subsequent file creation reinforces the wrong path — if the agent creates \`util/constants.py\` to support \`util/helpers.py\`, the wrong directory grows. Humans debugging later find files in both locations and can't determine which is canonical. The root cause is that file creation succeeds at any valid path, so there's no natural correction mechanism. Path manifests and immediate verification break this cycle.
