about

nx_email_retrieve.nx -- EMAIL RUNG R4: POP3 + IMAP retrieval codec. module: nishi-core.email.retrieve depends: (none -- pure RFC 1939 / RFC 3501 line codec) capability: CORE_EMAIL The client side of FETCHING mail (the receive counterpart to R1's SMTP send). Pure parse/build over caller buffers -- no syscalls, so it gates offline against scripted server transcripts; the live socket wiring is a later nx_email_retrieve_io.nx (the nx_dns/nx_dns_io split). POP3 (RFC 1939): "+OK"/"-ERR" status, STAT count/octets, a generic command builder, and multi-line handling -- de-dot-stuffing (the inverse of R1's SMTP dot-stuffing: a body "." line is sent as ".." and a lone "." terminates) plus terminator detection. IMAP4rev1 (RFC 3501): tagged command builder, tagged-completion status (OK/NO/BAD) that correctly SKIPS untagged "*" data lines (the classic "* OK ..." vs "A001 OK ..." confusion), and literal "{n}" octet-count parse. license_tier: INDEPENDENT_REDERIVE genealogy_id: international-research-sources/ietf/rfc_1939 + rfc_3501 lineage_id: nishi_email_retrieve_r4 nx_safety_envelope: intended_use: "POP3/IMAP client response parse + command build. Mail retrieval substrate." sil_target: SIL2 (mis-parse drops/duplicates mail) evidence: [RFC_1939_3501_basis, pop3_dedot_inverse, imap_tagged_vs_untagged, literal_size] hazard_register: [bug-tape-pop3-dot-unstuff, bug-tape-imap-untagged-confusion] residual_risk: "IMAP literal continuation streaming + UIDPLUS/ CONDSTORE extensions are later sub-rungs." verdict: NOT_YET_EVALUATED
