the largest lift and the one most dependent on a real workflow (§7).
- Compile-time model use (one-time labeling/risk/param proposal) lands here,
guarded to preserve the runtime's $0/0-call property.
- **Status:** §3 step [3] (interactive disambiguation) shipped in
`compiler/disambiguation.py`; §3 steps [4]+[5] (multi-trace induction +
held-out validation / quarantine) shipped in `compiler/induction.py`
(`induce_program` / `validate_held_out` / `reproduction_score`). Structural
alignment infers params (values that VARY across traces), loops (a repeated
body whose count DIFFERS), branches (a divergent step under a detectable
condition — guard proposed/flagged), and optional steps — all deterministic,
ZERO model calls; the optional compile-time `Proposer` only PROPOSES (flagged,
never trusted). Contradictory / underdetermined traces are QUARANTINED (no
program emitted, `certified=False`) and routed to the disambiguation flow.

### Stays as-is (do not rebuild)
