 131/-! ## L-3: LNAL 5-op Semantic Core
 132
 133### Theorems (cite freely)
 134- `LNAL.Core.Sequence.reduce_idem` — normal form is idempotent
 135- `LNAL.Core.Sequence.reduce_only_structural` — reduced sequences contain only LOCK/legal-BRAID
 136- `LNAL.Core.Sequence.reduce_length_le` — reduction does not increase length
 137- `LNAL.Core.Op.normalize_bind_self` — double normalize = single normalize
 138- `LNAL.Core.Sequence.exec_equiv_refl/symm/trans` — execution equivalence is an equivalence relation
 139
 140### Definitions (must declare)
 141- `Op` — 5-op inductive: LISTEN, LOCK, BALANCE, FOLD, BRAID
 142- `LedgerState` — windows + Z/M ledgers + lock flag
 143- `NeutralWindow` — length-8 window with small sum
 144- `LegalTriad` — pairwise-distinct triple (SU(3) stand-in)
 145
 146### Known limitations (must acknowledge)
 147- `Op.execute` is identity (scaffold) — no operational semantics in this paper
 148- `Sequence.execute_eq_state` proves execution is no-op (from scaffold)
 149- Static invariants (8-tick sum, parity, cost ceiling) referenced in doc but
 150  formalized in separate files, not in Core.lean itself
 151
 152### Vocabulary note for paper
 153- 5 ops = semantic core (this paper)
 154- 8 ops = ISA / VM primitives (separate L-4 paper)
 155- "16 opcodes" in LNAL.lean aggregator is WRONG — it describes program length, not arity
 156
 157### Out of scope for L-3
 158- Full execution semantics (L-4)
 159- Completeness / unique decomposition (U-3)
 160- Photon-meaning bridge
 161- Language emergence
