+## Measured through dialogs and recordings
+
+Measured on 2026-11-01 in two ways: by running the event with its dialog and pressing OK (the reference
+application then returns the full descriptor), and by recording actions through the menus and reading
+the recorded steps back from the saved Actions panel. Ranges come from the dialog's own "a value between
+… is required" message.
+

+|---|---|---|
+| Custom (`Cstm`) | `Scl ` long 1..9999, `Ofst` long -9999..9999, `Mtrx` list of 25 longs -999..999 | Without the dialog the step needs all 25 cells, or the application fails. |
+| Fibers (`Fbrs`) | `Vrnc` long 1..64, `Strg` long 1..64, `RndS` long (seed) | |
+| Displace (`Dspl`) | `HrzS`, `VrtS` long -999..999; `DspM` (`StrF` stretch to fit, or tile); `UndA` (`RptE` repeat edge pixels, or wrap around); `DspF` alias: path of the displacement map (.psd) | The map file is chosen after OK. |
+| Color Lookup (`colorLookup`) | `lookupType` (`colorLookupType`: `3DLUT`, abstract, device link); `Nm  ` text: the file's path; `Dthr` bool; `profile` raw data (ICC); `LUTFormat` (`LUTFormatType`, e.g. `LUTFormatLOOK`); `LUT3DFileData` raw data: the LUT file itself; `LUT3DFileName` text | The LUT travels inside the step. |

+### Batch
+
+Running Batch while recording records the steps the batch played, not a Batch step. The Batch
+descriptor itself (`Btch`, as the dialog returns it):
+
+| Key | Type | Meaning |
+|---|---|---|
+| `null` | alias | source folder (absent for open files) |
+| `Fldr` | bool | include all subfolders |
+| `suppressWarnings` | bool | suppress colour profile warnings |
+| `Usng` | reference | the action: `Actn` by name in `ASet` by name |
+| `T   ` | alias | destination folder |
+| `fileNamingRules` | object | file naming (below) |
+| `Log ` | alias | folder of the error log ("log errors to file") |
+| `Nm  ` | text | error log file name |
+
+`fileNamingRules`: `fileNamingComponents` (list of up to six objects; each is `component` enum
+`fileNamingComponent`, or `Txt ` text for typed text), `Strt` long (starting serial number), `Mcnt`, `Win `,
+`unix` bool (compatibility).
+
+| Component | Menu entry |
+|---|---|
+| `Nm  ` / `lowerCase` / `upperCase` | Document Name / document name / DOCUMENT NAME |
+| `oneDigit` `twoDigit` `threeDigit` `fourDigit` | 1, 2, 3, 4 digit serial number |
+| `lowerCaseSerial` / `upperCaseSerial` | serial letter (a, b, c…) / (A, B, C…) |
+| `mmddyy` `yyyymmdd` `yymmdd` `yyddmm` `ddmmyy` | dates |
+| `lowerCaseExtension` / `upperCaseExtension` | extension / EXTENSION |
+
+The extension component has no dot: Document Name + extension + 3 digit serial + "_pc", starting at 5,
+named `other.png` → `otherpng005_pc` (the saved file then gets its own extension). The two remaining date
+entries (mmdd, ddmm) did not accept `mmdd`/`ddmm`; their values are still unknown.

-| Fibers (`Vrnc`, `Strg` ranges) | Values outside the dialog's range are returned unchanged, not clamped; the limits come from the dialog. |
