+# Dev opt-level 0 for workspace glue crates (every tracedecay-* crate that is
+# not a profile.perf kernel below). A `cargo build -p tracedecay-cli --timings`
+# audit on 8 cores found the wall-time critical path is a serial chain of
+# workspace crates whose cost is ~85% LLVM codegen at dev opt-level 1:
+# rusqlite-runtime (96s codegen), tracedecay (69s), daemon-service (49s),
+# mcp (35s), application (142s, off-path but fan-out). Compiling dispatch,
+# DTO, and plumbing crates unoptimized cut a cold build from 461s to 345s
+# wall (-25%) and workspace CPU by ~45% (measured). The perf-pinned kernels
+# (code-index, rusqlite-runtime, store, grafeo-*, ...) keep dev opt-level 1 so
+# local tests keep optimized engine code; the perf mirror pins preserve every
+# crate's previous perf level since `perf` inherits dev overrides.
