+# What a macro call still costs after its arguments moved to slots
+
+**Problem.** After 0117 P2 (#434) Render/macros fell 13.5%, short of the plan's
+-20..-25%. A profile of `MacroStatement::InvokeMacroRenderer` on the `macros` case
+(callgrind, `--dump-instr=yes`, self cost by source line) puts the rest of a call, besides
+rendering the body, at:
+- about 230 instructions copying each argument out of the `const CallParams&` into its
+  slot (variant copies and shared_ptr reference counts); the call site owns the
+  evaluated arguments and could move them, but the callable signature takes them by
+  const reference;
+- about 100 taking and giving back the frame (`RenderWorkspace::Take`/`Release`);
+- about 140 checking the arguments (`CheckMacroCallArgs`, the `any_of` over defaults, the
+  keyword pre-lookup), most of which depends only on the macro and could be computed at
+  Load.
+
+**Proposal.** Measure each separately: pass evaluated arguments by rvalue to macro
+callables (an internal overload; user callables keep theirs), precompute the per-macro
+flags at Load, and a frame fast path for a unit whose frame is the same size as the
+previous call's. Filed at the perf track's request (2026-10-08).
+
+**API note for Ruslan.** The rvalue path is meant to stay internal: macros and other
+callables the engine makes get an extra overload that takes the evaluated arguments by
+value or rvalue. The public `user_callable.h` signatures are unchanged. It is listed in
+`touches` only because the internal overload may sit next to the public one. If it can
+live entirely in src/, the public header drops out of `touches`.

+# Skip the lookup cache for names that are read once per render
+
+**Problem.** The lookup cache keys an entry by the name node and the render's epoch, and
+every render takes a new epoch (0118 P5b deleted the cache's `Forget`). A name node
+outside any loop, macro body or call block runs at most once per render, so it always
+misses: the cache only costs it the probe and the insert. After 0118 P5b-3a a miss also
+reads the name through the tree's view, 3 instructions more than before (a hit 3 fewer).
+Render/large_static (50 `{{ title }}` nodes, all outside loops) rose 0.55%, inheritance
+0.43%; the perf track accepted that as a miss/hit trade (suite Render -0.16%) on condition
+that this task is filed.
+
+**Proposal.** The name resolver knows at parse time whether a use sits inside a loop, a
+macro or a call body (its frames). Set a flag on `ValueRefExpression` for the uses that do
+not, and let them go straight to `FindValue`, skipping the cache slot (and its `NewSlot`).
+Measure Render on flat templates (large_static, substitute, config_file, inheritance), and
+check that loops do not lose: a macro body is re-entered per call and an included template
+per include, so those stay cached.
+
+**Done when** the flat cases' Render falls by at least the P5b-3a miss cost and no case
+rises past 0.3%.
