 Staging left on the box under `E:\psrem-stage\fe89363b\` (zip, unpacked tree, migration SQL, prep + swap
 scripts, `.reg` exports). The `_appsettings-keep-20260928T095846` copy and `*.bak.20260928T095846`
 directories can go once the build has soaked.

+# Second window, same day — `fe89363b` → `b3021e7c` (script file access + recipe-parsing receiver)
+
+**Build:** `main` @ `b3021e7c` (ProductVersion `1.0.0+b3021e7c5ff68ba20abc510f644045c7dbbccd86`; zip
+125 585 217 B, SHA-256 `5b7d7c68…2d66df`). **Delta:** the read-only, allow-listed `Files` script global
+(design `docs/plans/2026-09-28-script-file-access-design.md`) and the TestMesMachine Delmia simulator now
+reading + parsing the downloaded recipe file. **No migrations** (57 before and after — asserted, nothing applied).
+
+**Config (the only change):** `appsettings.Site.json` gained
+`ScadaBridge:SiteRuntime:ScriptFileAccess:AllowedRoots = ["E:\\ApiInstall\\ScadaBridge\\recipes"]` (+ a
+`_comment_SiteRuntime`), edited on the Mac and pushed over SMB **before** the window so the swap script's
+keep/restore carried it through (new SHA-256 `3E7AD9A4…`); original saved as
+`E:\psrem-stage\b3021e7c\appsettings.Site.json.pre-b3021e7c`. The three sample recipes
+(`docker/recipes/SBTEST-R100.txt`, `SBTEST-R200.txt`, `SBTEST-R900-invalid.txt`) were pushed to
+`E:\ApiInstall\ScadaBridge\recipes\`. Central's appsettings unchanged.
+
+**Window:** prep 10:41:47 (COPY_ONLY backup `ScadaBridge_pre-b3021e7c_20260928T104147.bak`, 140 064 768 B,
+VERIFYONLY valid); swap 10:42:08 → site ready 10:42:57 (**~50 s**); the swap script asserted the recipes root
+(3 files) and logged `site AllowedRoots = E:\ApiInstall\ScadaBridge\recipes`; boot validation accepted it.
+Backups: `app.bak.20260928T104207` / `cli.bak.20260928T104207`.
+
+**Re-seed + gate:** `seed-mes-test-machine.sh` added the 14 recipe attributes to `TestDelmiaReceiver` and
+updated all nine scripts; `verify-mes-test-machine.sh` (with `RECIPE_ROOT='E:\ApiInstall\ScadaBridge\recipes'`,
+`RECIPE_OUTSIDE='E:\ApiInstall\ScadaBridge\app\appsettings.Site.json'`) **PASS 31/31** — group A now proves
+accept (12 typed values loaded), re-download, invalid-line rejection with line numbers and nothing loaded,
+`NotFound`, and a file **outside** the root refused (`OutsideAllowedRoots`). Real HTTP with a key:
+
+```
+DelmiaRecipeDownload R100  -> {"Result":true,"ResultText":"Loaded 12 recipe values from SBTEST-R100.txt for WO-1001"}
+DelmiaRecipeDownload R900  -> {"Result":false,"ResultText":"Recipe rejected: line 4: expected RecipeValueName,RecipeValue;
+                                line 5: unknown recipe value 'MysterySetting'; line 6: PotTempSP expects Int32, got '980.5'"}
+```
+
+**Recipe file format** (`RecipeValueName,RecipeValue` per line; value = int / double (invariant `.`) / bool /
+text; `#` comments and blank lines ignored; everything after the first comma is the value; surrounding double
+quotes unwrapped). Loaded all-or-nothing into `TestDelmiaReceiver`'s typed recipe tags (`RecipeName`,
+`RecipeRevision`, `CoatingType`, `ReactorTempSP`, `PotTempSP`, `ArgonFlowSP`, `HydrogenFlowSP`,
+`ChlorineFlowSP`, `VacuumSP`, `TargetRuntime`, `PurgeEnabled`, `OperatorNote`) plus `RecipeValueCount` /
+`RecipeLoadedFile`. To test your own file: drop it in `E:\ApiInstall\ScadaBridge\recipes\` (SMB) and call
+`DelmiaRecipeDownload` with that full path.
+
+**Rollback:** stop Site + Central, rename `app` → `app.failed`, `app.bak.20260928T104207` → `app` (same for
+`cli`), restore `appsettings.Site.json.pre-b3021e7c` if the key must go (the old build ignores it), start
+Central then Site. No DB restore needed (no schema change).
+
+**Rig:** `docker/deploy.sh` from `b3021e7c` (site-a both nodes mount `docker/recipes` read-only at
+`/app/recipes`, `AllowedRoots ["/app/recipes"]`); seeded on site-a; `VERIFY_GROUPS=AD` **PASS 8/8**.
