 | OSTW-exercised params/spellings and enum domains (CreateEffect, Workshop Setting, Hero/Map/Button/Icon/Operation/Rounding/InworldTextRev, …) | Pinned OSTW v3.4.0 reference probe emissions (P4/P5/P6/P6b) and the protect-ban entry-point reachable closure. |
 | Parameter metadata (`paramDomains`, `paramDefaults`, `paramCoercions`) | Pinned-reference probe data, never copied from upstream game data. Contextual literal substitutions are recorded per parameter position and cross-checked against [OverPy's replacement metadata](https://github.com/Zezombye/overpy/blob/2002431649cbdd7ddc3aa70bd184b598ec2820e5/src/types.d.ts), [Workshop emission path](https://github.com/Zezombye/overpy/blob/2002431649cbdd7ddc3aa70bd184b598ec2820e5/src/compiler/astToWorkshop.ts), and [Wait Until handling](https://github.com/Zezombye/overpy/blob/2002431649cbdd7ddc3aa70bd184b598ec2820e5/src/compiler/functions/waitUntil.ts); they do not establish global type coercions. |
 | Boolean parameter acceptance (typed rule in `values/validate.rs`, not catalog data) | [ADR-0014](../adr/0014-validation-evidence-for-slot-acceptance.md): OverPy wraps values in `First Of` keyed on the `Boolean` parameter type ([`astToWorkshop.ts`](https://github.com/Zezombye/overpy/blob/1e2688954302a402d076944b46db07efb14d7b61/src/compiler/astToWorkshop.ts)), and the fix for Zezombye/overpy#182 states every value can be put in a Boolean field. The values the client rejects there are not modelled. |
+| `First Of` argument (`paramTypes[0]`: `Any`) | [ADR-0014](../adr/0014-validation-evidence-for-slot-acceptance.md): pinned OverPy 9.7.10 wraps a value the client rejects in a Boolean parameter as `First Of(<value>)` ([`astToWorkshop.ts`](https://github.com/Zezombye/overpy/blob/1e2688954302a402d076944b46db07efb14d7b61/src/compiler/astToWorkshop.ts)), so the wrapper's argument is any value (Vector, Hero, Team, Map, Color, Button, Game Mode, …). The rule is keyed on the wrapped form, not on an array; the `Array|EntityId` declaration was a presumption only. |
 | Localized parameter labels (`paramAliases`) | Separately reviewed owner mappings, stored per declared parameter position and resolved only through the catalog API. The initial `Wait` `zh-CN` labels are `时间` and `等待行为`, as identified by the documented Chinese Workshop action reference at https://overwatch.huijiwiki.com/wiki/%E5%9C%B0%E5%9B%BE%E5%B7%A5%E5%9D%8A/%E5%8A%A8%E4%BD%9C (accessed 2026-09-11); the canonical parameter order and descriptions are cross-checked against the pinned `workshop-data` action definition. They are not generated by the general zh-CN corpus pipeline. |
 | Action/Value parameter and return signatures | Workshop.codes structured article properties (Returns, Parameters, Type, and Default), cross-checked against the pinned OverPy metadata and static OSTW data; entries without convergent sources remain explicitly unresolved. Representative article links are recorded with the catalog entries. |
 | `Create Dummy Bot` hero parameter union (`Hero|Array`) | Workshop behavior accepts a single Hero or Hero array and selects randomly when multiple heroes are provided; pinned OverPy 9.7.10 texture-tag setup emits `getAllHeroes()` into `Create Dummy Bot`. |
