widgetAction derives the form from the request (create without record_id,
update with one) and answers 404 when the field's context hides the
widget on that form, reusing contextAllows as the save path does. An
update-only action can no longer run with a nil record through a direct
POST.
isJSONScalar now encodes each value and keeps it only when the encoding
is a string, number, boolean or null, so a named scalar whose MarshalJSON
writes an array or object, NaN and the infinities are dropped. writeJSON
encodes into a buffer before the status line, so an encode failure is a
logged 500 with the generic envelope instead of a 200 with a truncated
body.
- boardwalk exports ContentType and SetSecurityHeaders
- pact.AdminClientAssets files are read and hashed at boot and served by exact
key under {prefix}/assets/{vendor}/{plugin}/ with nosniff, CSP, CORP,
no-cache and an ETag; a miss falls through to the SPA
- list and form schemas carry assets URLs with a ?v= hash
- toolbar.buttons resolves create, delete and registered actions after decode;
toolbarActions is permission-filtered per admin
- POST .../toolbar/{action} behind requireAjax and action permissions
- pact: AdminClientAssets, AdminAction, AdminActionInput, AdminActionResult,
HasAdminActions and AdminPartialData contracts
- fields.yaml type: widget with widget, action and fill keys; boot checks the
plugin tag prefix, the registered action and writable scalar fill fields
- POST .../widgets/{field} behind requireAjax, controller and action
permissions, scoped non-locking record read and a server-side fill filter
- typed OpenAPI operation, inventories and an acme conformance case
