about
nx_doc_at_rest_gate.nx -- MEASURED hermetic gate for the at-rest wiring (nx_doc_at_rest). Fresh nonce domain per
run (sys_now_realtime_sec). Proves encrypt-on-write + transparent read + legacy coexistence + crypto-shred:
T1 doc_put a confidential doc -> the STORED bytes start with the NXENC1 magic (encrypted, NOT plaintext) and
doc_get round-trips BYTE-IDENTICAL.
T2 a LEGACY plaintext value (raw ss_add, no magic, in the confidential shard) -> doc_get passes it through
unchanged (existing pre-encryption docs still readable).
T3 the raw STORED encrypted bytes DO NOT contain the doc's distinctive plaintext canary (at-rest protection).
T4 crypto_shred(domain) -> doc_get of the encrypted doc FAILS (erased) while the legacy-plaintext doc reads.
Print pass=4 + GREEN/RED, append knowledge/status/dp_at_rest_gate.log. STANDALONE -- no daemon, no deploy.
(nx_chacha20_poly1305_decrypt prints one 'A' to STDERR on first call -- shipped-AEAD scratch marker; harmless.)
