The host post-pass folds the benign `Product(Linear(param), Linear(non_param))` shape on unary-parameter binds to a single `Linear(param)` for the gate #78 oracle. **Fold / regen coupling:** `lens_cost_symbolic::compute_symbolic_costs` hand-mirrors the generated lens fold (`generated::seed_bind_params`, `entry_for`, prepend-to-accumulator order) so collapse runs on each `Hit` before the row is visible to downstream `lookup_cost`; if `regen_lens` changes that fold’s seed, ordering, or `entry_for` shape, this wrapper can **silently desync** — mitigation is the same wave as below (algebra-side iterate/normalize, canonical induction `PortId`, **or** a regen-emitted per-row post-hook so the host is not a second copy of fold control flow). **Dissolution trigger:** lift alias-aware folding into `algebra.dag` `iterate` / `normalize` (or canonical induction `PortId` in lowering) so `.dag`-emitted `symbolic_cost_of` needs no wrapper; cross-ref **DB-7** ([docs/db-history/db-7.md](docs/db-history/db-7.md)) and **F8** (`SymbolicCost` semiring witness, line 636 above). **Test-side `span.file` bridge (P5):** `cost_lens_symbolic_consumer_test.rs` pairs the `compile_to_dag` fixture label with `TransformNode.span.file ==` when asserting `per_call_pattern_at` hits — dissolve when lowering exposes a structural fixture/subprogram witness so integration tests need not filter on path strings (same dissolution wave as the host wrapper).

+**§3.1.1 `SameArgumentCall` vs recursive `Transform` dispatch (P3).** When `per_call_pattern_at` returns `Some(pattern)`, [`src/v3/lenses/cost.dag`](../src/v3/lenses/cost.dag) routes every matched recursive callable through `recursive_transform_cost` / `pattern_to_iter_bound` — **not** through the operand-sum path `transform_cost_for_target`. For `SameArgumentCall`, `pattern_to_iter_bound` is **`Miss`**, so `combine_iterate` yields **`Miss`** and the transform’s result port carries **no** `Hit` symbolic-cost row from this lens slice (fail-closed). That is a deliberate narrowing versus treating same-argument self-call as operand-cost summation: here same-arg is **not** a recurrence dimension with an iterate bound (see §3.1 table and comments at `recursive_transform_cost` / `pattern_to_iter_bound` in `cost.dag`). Cementing expectations live with gate **#78** / consumer integration routes that compile real countdown fixtures; paths that only prove `SameArgumentCall` without a descent witness remain absent-cost unless elsewhere modeled.

 ### §3.2 Where the consumer attaches in the lens
 
 The cost lens's existing `entry_for` dispatch on `Behavior` (in [`src/v3/lenses/cost.dag`](../src/v3/lenses/cost.dag) lines 102–118) gets one new case for the recursive-call sub-case of `Transform`:
