Screenplay models can now say whether a part of an application is there at all for a tenant, a user or the system, separately from who is allowed to use it.

Added

• audience and reusable availability declarations with for, when and with lines, combined with and, or and parentheses, and available for, available when and available with gates on modules, features, slices, commands, queries and screens. Gates combine down the path and are decided before authorize; an unknown audience, availability or value never opens a gate (Audiences and availability: audience, availability, available for | when | with #1301)
• Persona audience lines, for authoring only, and the $context.audiences value.
• provide <name> <Type> from <source> for scope-driven context values readable in available when.
• ESM v53, written only when a model uses availability or provided values.
• Diagnostics PLAY1130 to PLAY1141 for malformed, duplicate, unknown and circular audiences and availabilities, unprovided values, and commands that can be unavailable to their invoker.
• The same support in the TypeScript compiler, Monaco (hover, completion, go to definition, snippets), the VS Code grammar, rename and the MCP server. The event model board draws a gated slice for the personas that pass its gates and marks it.
• A documentation page on audiences and availability, and gates in the Invoicing and Commerce samples.

Changed

• provide is admitted when its source is a literal, the host or a query; provide from a file or code block stays a preview.

Corpus impact: tracked in Cratis/AI#1144 (Cratis/AI#1144).

Reviewer notes:

• Surfaces covered: C# and TypeScript compilers, ESM v53, printer, rename, MCP, Monaco, VS Code grammar, event model board, documentation, samples (Invoicing with the Monaco copy, Commerce).
• Commerce shows a scope-driven gate: Fulfillment provides warehouse, Shipping gates on it.
• provide from a file or code block remains a preview (Context values: provide at application, module, feature and slice #1300).
• Verified locally: Screenplay.Specs 17703, Screenplay.Mcp 3608, TypeScript compiler 9743, Monaco, VS Code extension 1048, event model board 407, McpApp 133; Release build with warnings as errors for Screenplay, Specs, Mcp, Tool and Conformance.
• Not run: Screenplay.CanonicalVectors.Specs (its LegacyReader project fails restore here with NU1507, a local NuGet source setting).
