Six-client guide qualification

CI run 35509915448, attempt 1 passes the native provider matrix for PR #418. The tested merge revision is 52819edceba07106ac94d6161fcdb5e561aafc0b, with PR head 8dfcc11583a718a9da2f65ff2f2b162d68a452d6. Every registered snippet source and its validation script have identical Git blob bytes at those two revisions. The 18 example records bind those exact source and validation hashes to the reachable PR head; they do not treat later edits as already executed.

The files in this directory preserve the seven original JSON receipts from the run's phase-1-bounded-conformance artifact. matrix.json binds each language receipt by SHA-256 and records the common CLI, node and signed fixture hashes. Rust, TypeScript, Go, C, Java and C# each pass 18 assertions: 108 assertions, 54 activation IDs, six policy operation receipts, 24 physically closed held requests, six clean node shutdowns and fully reaped client owners. The controlled upstream records no unauthorized or unexpected requests.

These are real native clients against separately owned authenticated nodes, executed HTTP/blob guests and a controlled HTTP provider. The evidence does not qualify a browser client, installed release bundle, external provider vendor, resource campaign or newcomer pedagogy review. The latter remains pending in #358.
