Migrate MCP session tests to the named lifecycle output schema and preserve raw reply envelopes. Move R8 type/alias checks to the production field resolver and recovery guidance checks to their scoped factory; remove superseded test-only exports and an unused import.
Validation: 99 focused tests, an exact-old-schema negative control, full selected CI including all 8 shards and source tests, and Greptile source review passed. Fresh-head real stdio MCP analyzed fast-deep-equal@3.1.3 and retained a complete authenticated Evidence bundle after close; compact/full catalogs are unchanged. Full local typed lint hit the 3 GiB memory guard; scoped typed lint passed. Codex review quota exhausted.
Fixes#7513.
* fix(mcp): escalate transient failures before asking for a restart
Give dropped connections and startup failures one bounded retry, then a
scripted handoff to the user. Point timeout recovery at a named request
field or REA_* setting instead of telling agents those limits are fixed.

* fix(process): stop unexpected command failures from recommending a retry
The catch can already have launched the target, and the projection stays
non-retryable. Tell the user to check the inputs and run doctor instead.

* fix(mcp): limit retries to safe calls and recommended settings
A dropped connection may already have changed the target, and a bad
catalog rejects the same startup every time. Retry only a repeatable
call, and change a setting only when the remediation recommends it.

* test(mcp): match recovery guidance across wrapped lines
Startup handoff capitalization and markdown wrapping still carry the
same sentences. Compare the prose with whitespace collapsed.

Teach client deadline recovery before REA results can be discarded, distinguish
producer-owned server budgets, and preserve Evidence/cleanup uncertainty.
Include actual Codex CLI recovery probes and CLI/MCP regression coverage.
