Retain exact empty and computed literal keys in JavaScript observations. Bind CDP response bodies to request occurrences, account for late responses, and validate the target after final progress callbacks.
Require observed request method and initiator metadata instead of inventing defaults. Preserve valid redirect history while excluding later events for malformed reused IDs. Keep unavailable or invalid encoded lengths unknown and retain valid zero values.
Validation: 57 CDP boundary tests plus temporary-directory hygiene and combined checks. Protocol events come from the fake CDP server; no live browser verification is claimed.
Retain source URLs, empty connections, and ordered frame streams. Compare same-URL streams without relying on transient request IDs, and compare selected shapes and byte counts only through common known coverage. Malformed binary frames retain known metadata with an unknown byte count.
BREAKING CHANGE: inspect_web_page network.websocket_events is replaced by network.websocket_connections, whose records contain request_id, url, and events. Frame payload_bytes is nullable when decoding cannot establish its size. No legacy alias is retained.
Validation: 78 domain/browser/MCP focused tests, check:fast, docs:check, and real Chrome 154 CDP capture passed. Real capture retained six connections and twelve frames with source URLs and selected shapes. Full browser verifier was interrupted during an unrelated slow scenario stage; its assertions were exercised by the bounded capture proof.
Accumulate observations once per structural path instead of allocating and serializing a path for every payload value. Remove the CDP body-shape wrapper and retain primitive, empty-array, and literal-property semantics.
Validation: CDP capture/comparison regressions and CLI/MCP boundary checks pass; 1,507 differential cases match the previous implementation. A 2.5 MB repeated-row workload improves from 105.0 ms to 14.6 ms warm median across alternating runs. Real browser providers were not exercised.
Retain primitive and nested array types with typed paths, and compare only mutually observed body shapes while preserving selected coverage uncertainty. Return full untrusted WebMCP input declarations with canonical digests, without resolving references or invoking tools.
BREAKING CHANGE: JSON shape paths now contain typed property and array-element segments. WebMCP input_schema_shape is replaced by input_schema and input_schema_sha256, retaining declared examples and defaults.
