+## Phase A progress update (recap)
+
+### FFT transform (found)
+- **Recursive FFT planners ("giants")**: 7 monolith funcs (~14.4K each) = type variants:
+  18001f260, 1800246e0, 18002f980, 180029ca0, 180035980, 18003b900, 18004ff80
+  Recurse on `log2 - factor` with `param_5+1` depth; build stage plan in `param_1+0x78` array.
+- **Factor tables** (int, index=log2): `DAT_181c5e0fc` (small=4/8/9/13), `DAT_181c5e15c`,
+  `DAT_181c5e3fc` (nonzero => use giant path in FUN_18003b6c0).
+- **FUN_18003b6c0** (bit-reverse+plan, N big): if `DAT_181c5e3fc[log2]!=0` call giant `FUN_18003b900`,
+  else small plan via DAT_181c5e4e0 XOR mask permute.
+- **Base small FFT**: `FUN_18002e360` (radix2/3), `FUN_180023860` (float variant).
+- **Twiddle**: copied from static base `DAT_182616800` into scratch by `FUN_180039b00`.
+- **Spec init FUN_180008140** (from dispatch table `182615ef0`): builds plan; dispatch-only callers.
+- Giants/planners = integer address gen (no float math) => executors are separate (dispatch kernels).
+
+### Spectral layer located (named C++ classes via RTTI):
+- `SpectralProcessor<float,7,1>` vtbl @180529610 (1154) + methods around 180529xxx/18052exxx.
+- `Soothe2Module<float,1>`, `Soothe2ModuleBase`, `IIRFilterExtended<float,1>`, ModuleDecryptor.
+- range 0x180500000-0x180530000 listed (1051 fns) -> funs_range.txt overwritten.
+
+### Block processor chain (audio->out):
+- `FUN_18052e260(param_1, n)` : reads det? calls **FUN_180536300(param_1+0x3d8, in, out, det, n)**
+- `FUN_180536300` (475): normalize `DAT_1824c4248/(freq)`, FUN_18052da00/db50/d990/dbc0 (smoothing),
+  FUN_180535880, FUN_180536f90 (249, detector update via dispatch).
+- Param setup fns: FUN_18052e9b0 (3167), FUN_180529fe0 (2051) — float math on params (DAT_18262b700 block-sizes etc.).
