OriginWeave Protocol versioning remains independent and cannot be changed by MCP metadata. +PR #293 is a separate active, stacked browser-adapter slice on top of presentation-identity prerequisite #229. It introduces a narrow `originweave-bidi` capability boundary pinned to the 18 August 2026 WebDriver BiDi Working Draft. The capability map delegates complete-profile admission to `originweave-fingerprint` and intentionally excludes `HardwareConcurrency` and `Platform`: current standard BiDi cannot represent those complete Chromium presentation surfaces, so standard BiDi alone must return the kernel's `MissingSurface(HardwareConcurrency)` result rather than accept ambient host values. This branch-local slice does not send WebDriver BiDi commands, create a generic DevTools pass-through, apply a profile to Chromium, or produce page-observed presentation evidence. Those remain #292 follow-up work and require exact-head verification plus a version-pinned Chromium/CDP adapter for the Chromium-only remainder. + ## Consequences OriginWeave carries adapter maintenance and version negotiation but gains a durable customer API. Multiple browser/control transports can coexist. New upstream capabilities do not silently change risk or action semantics. Compatibility matrices become release artifacts. ## Failure and degraded behavior -Adapter negotiation failure disables only affected capabilities. Unsupported or schema-incompatible messages fail closed with typed errors. OriginWeave must not bypass a failed adapter by exposing raw CDP or arbitrary JavaScript to an autonomous model. A standards adapter may fall back to a pinned vendor adapter only when the same OriginWeave semantic and security contract is proven. +Adapter negotiation failure disables only affected capabilities. Unsupported or schema-incompatible messages fail closed with typed errors. OriginWeave must not bypass a failed adapter by exposing raw CDP or arbitrary JavaScript to an autonomous model. A standards adapter may fall back to a pinned vendor adapter only when the same OriginWeave semantic and security contract is proven. A partial presentation-emulation capability set is unsupported for complete-profile admission; it cannot be completed with ambient browser values. ## Security / privacy / governance impact Protocol validation occurs before messages influence policy. Tool/page-provided strings remain untrusted. Method and tool routing metadata is shape-bounded before correlation, preventing malformed or oversized untrusted routing strings from being reinterpreted through mismatch handling. Secret handles never become raw secret protocol payloads; only the separately authorized trusted broker-to-browser delivery path may materialize the value, and that value does not pass through MCP, WebMCP, BiDi observation, or model-visible CDP output. Adapter version/provenance is recorded for audit and incident reconstruction. +For presentation emulation, protocol availability is not presentation evidence. The adapter must bind its capability claim to an explicit protocol/browser revision, fail closed on missing required surfaces, and later prove page-visible state after application. Neither a protocol command acknowledgement nor an unobserved browser setting is sufficient evidence. + ## Tests and acceptance evidence Require version-negotiation tests, schema/property tests, malformed-message tests, BiDi/CDP semantic parity tests for shared capabilities, WebMCP prompt-injection tests, MCP authority-separation and version-change tests, browser-version compatibility matrices, and end-to-end proof that unsupported capabilities fail without side effects. For the protected-main `tools/call` foundation, acceptance includes deterministic method and tool-name bounds/syntax, exact header/body method and tool-name correlation only after both sides are bounded, explicit invalid-method/invalid-tool-name/unknown-tool rejection, one unambiguous tool-to-action registry, independent capability/risk expectations, route/action mismatch denial before ordinary policy evaluation, exact 100% owned-production coverage, and integrated review evidence from PR #168. For active PR #170, exact-current acceptance additionally requires bounded protocol metadata before cross-field comparison, required client-capabilities presence, bounded `tools/list` method correlation, rejection of unissued cursors, deterministic result/cache semantics, exact 100% owned-production coverage, and unchanged-head CI/security/review evidence. These checks do not substitute for complete transport or adapter conformance. +For PR #293, acceptance of this first capability-boundary slice requires a regression that fails on #229 because no `originweave-bidi` bounded context or pinned presentation-capability map exists, then exact-head Rust/Python/rustdoc/Clippy/coverage verification that the minimal adapter compiles and that the pinned standard set fails with the canonical fingerprint-kernel missing-surface error. This is not acceptance of #292 as a whole. Real pinned-Chromium application, page-observed post-condition evidence, navigation/renderer/crash/cleanup behavior, and the Chromium-only CDP remainder still require realistic browser E2E. + ## Migration and rollback Adapters are independently versioned and can be canaried. Clients migrate through OriginWeave Protocol compatibility rules, not upstream protocol rewrites. Rollback pins a previously supported adapter/browser/protocol pair and records that pair in provenance. ## Open follow-ups -Define internal protocol versioning rules, adapter capability descriptors, minimum supported BiDi level, CDP pin policy, complete MCP Streamable HTTP/request-metadata validation, MCP transport serialization, authenticated deployment, and MCP/WebMCP schema isolation. +Define internal protocol versioning rules, complete MCP Streamable HTTP/request-metadata validation, MCP transport serialization, authenticated deployment, and MCP/WebMCP schema isolation.
