+# Programmability {#programmability}
+
+Fill in a secret index or payload after the key exists, rewrite an
+updatable leaf, or commit to a vector before choosing which coordinate
+to open.
+
+| Mechanism | What it does |
+| --- | --- |
+| [dpf::wildcard_value](@ref dpf/wildcard.hpp) | Placeholder input or leaf. Eval throws until you assign. |
+| Leaf assign | `compute_and_get_blinded_output_share`, `reconstruct_correction_word`, `async_assign_leaf`, `assign_cmp` — see [wildcard assign](@ref wildcard_assign). |
+| [dpf::updatable](@ref dpf/placement.hpp) | Beaver leaf so a later rewrite replaces the payload without regenerating the spine. |
+| [dpf::ppvc](@ref ppvc_manual) | Point-programmable vector commitment: bind `(Z/2^s Z)^n`, then open one hidden coordinate (or the sum). |
+| [dpf::at](@ref dpf/placement.hpp) / `idpf` | Plant values on public prefixes as well as the leaf. |
+
+```cpp
+auto [k0, k1] = dpf::make_dpf(
+    std::uint8_t{12},
+    dpf::wildcard_value<std::uint32_t>{});
+// assign the payload later; eval before assign throws
+
+using scheme = dpf::ppvc<std::uint8_t, 8>;
+const auto pp = scheme::setup();
+const auto [com, st] = scheme::commit(pp);
+const auto op = scheme::open(st, 0, 0x5a, std::uint8_t{40});
+```
