    Orchestrator decision gate (2026-08-04)

    Campaign: campaign:0.1.8-beta2.

    This is a maintainer/coordinator decision, not a worker implementation ticket. It will review #62/#64/#65/#198 and explicitly approve or reject the generic native/adapt/omit/required-but-unavailable contract. No downstream #58 implementation or #318 publication work starts until this decision is recorded.

    Maintainer decision: GO for Beta2 implementation

    Accepted inputs:

    • ADR-0002 from 0.1.8 Beta2: Record the runtime-derived tool compatibility architecture (ADR-0002) #350;
    • exact CLI 0.146 structural inventory from 0.1.8 Beta2: Inventory Codex CLI 0.146 tool types and representative Responses lifecycles #62;
    • V1/V2 boundary from 0.1.8 Beta2: Define the Codex CLI 0.146 Collaboration V1/V2 schema boundary #64 and corruption guard from 0.1.8 Beta2: Isolate V1 repair from V2 namespace adaptation #198;
    • model-agnostic compatibility table from 0.1.8 Beta2: Define tool-type compatibility rules for custom Responses endpoints #65, merged by PR docs(issue65): add runtime tool compatibility table #362 at reviewed head c92441e.

    Approved contract:

    • The user-selected Provider/model is immutable; compatibility never selects another route.
    • Every declaration resolves to
      ative, �dapt, omit, or
      equired-but-unavailable.
    • Native-compatible shapes remain native; adapters are used only for incompatible, request-scoped, injective, reversible representations.
    • Unsupported optional hosted tools are not exposed; required unavailable tools fail before sampling.
    • No explicit or implicit cross-Provider proxy, Gateway tool execution, or Gateway agent scheduling exists.
    • Unknown custom endpoints use the same conservative type/protocol path; no named-model allowlist or production dispatch branch is authorized.
    • Beta2 implements only the generic compatibility foundation. Complete tool_search/Code Mode workflows remain Beta3; complete Collaboration V2 remains Beta4; maintained GLM/K2.7 regression remains Beta5.
    • Alternate-codec retry and model-output repair remain outside Beta2.

    Decision: GO to start #58. No unresolved product decision remains for its stated scope. This approval does not authorize a Beta2 tag or release; #318 remains the publication gate.
