8c06dcecc6* [Client] Speak the 2026-07-28 lifecycle On that revision the client opens with server/discover instead of initialize, stamps each request's _meta with the protocol version, its own capabilities and client info, and sends the standard Mcp-Method / Mcp-Name / Mcp-Param-* headers an intermediary routes on. ToolCatalog is what knows, from the tool list, which arguments a call has to mirror. An input_required result is answered rather than surfaced: InputRequestResolver asks the host's elicitation, sampling and roots handlers and retries the same request carrying inputResponses and the requestState the server sent. McpHeader holds the header names and the =?base64?…?= sentinel, so the two sides no longer keep their own copies of the same rules. * Fix CI baseline drift and address Copilot review findings Drop stale expected-failure entries the new client fixture now passes. Copilot review: fix McpHeader round-trip for a wrapper-shaped literal, encode empty/numeric-keyed inputResponses as a JSON object, stop the incident example repeating side effects on MRTR retry, and reset ToolCatalog on reconnect instead of carrying the previous server's verdicts. * Skip DualEraExampleTestCase on PHP 8.1 PHP_CLI_SERVER_WORKERS does not reliably fork multiple php -S workers there (php/php-src#9400), reproducing the single-worker deadlock the extra workers exist to avoid.
