docs: DECnet Phase IV configuration + usage guide (vms-30e) - #1097
Merged
Conversation
Operator-facing guide for the DECnet layered product, the sibling of docs/cluster-configuration-guide.md. Covers NCP node/executor configuration, inbound and outbound SET HOST, and honestly scopes out COPY/FAL-DAP as not-yet-implemented (decnet$task-to-task is absent in the register; cmd_copy() has no NODE:: handling and the FAL/DAP oracle capture is ground truth for a future implementation, not a shipped feature). Every capability claim is grounded in docs/compat/facilities/decnet.yaml and verified against ncp.c, dcl_cmd_set.c, and dcl_cmd_file.c on origin/main.

…s (vms-8c2/#1096) The guide was grounded on origin/main (pre-#1096), so §4 documented COPY-over- DECnet as not-yet-built. Since the guide (#1097) and FAL (#1096) both land in V0.6-13, augment §4 + the status table to the post-#1096 state: authenticated inbound FAL (object 17, connect-carried creds checked via SYSUAF/Purdy + disabled gate BEFORE accept, bad-pw refused), real DAP codec (bounded/fuzz-clean), RMS-over- ACP. Honest deferred: outbound DCL COPY bridge reports %COPY-I-NETNOTWIRED (rd vms-ea8), advanced DAP, byte-level stock-VAX interop. Clarified the ONE-authenticator bullet (interactive→LOGINOUT via $CREPRC; FAL→SYSUAF directly). MUST merge AFTER #1096 (it describes FAL, which #1096 delivers).

…cated SET HOST (hard-gated x86_64+Alpha+VAX) Version bump (identity + os-release in step, INV-1 SSOT gate). V0.6-13 ships: - DECnet Phase IV file COPY (FAL/DAP): object-17 FAL server + DAP codec + COPY client, authenticated against the real SYSUAF/Purdy with RMS-over-ACP transfer, byte-verified both directions (#1096, vms-8c2). - The authenticated inbound SET HOST -> LOGINOUT proof is now a HARD GATE on all three rails: DECNETD.EXE staged onto the VAX sysvol + Alpha boot image, so DECNETD-CTERM-ACCEPT + DECNETD-ISOLATION assert+PASS on x86_64 + Alpha + VAX — the login frontier is substrate-agnostic (#1099, vms-c1f). - DECnet Phase IV configuration + usage guide (#1097, vms-30e). - Compatibility-register honesty: cluster-dlm evidence repointed off deleted src/vmsscs paths to the executive-resident src/kernel-core, and the 4 cluster-dlm rows whose multi-node /dev/vms proof was retired in #1052 downgraded verified->implemented (#1100/#1101; multi-node proof re-establishment gated in vms-1ee).

Summary
docs/decnet-configuration-guide.md, the DECnet operator/admin guide — the sibling ofdocs/cluster-configuration-guide.md.AF_PACKET, object model, the ONE authenticator),NCPnode/executor configuration with worked examples, inbound + outboundSET HOST, and a honest "current status & limitations" table sourced fromdocs/compat/facilities/decnet.yaml.COPY NODE::reports%COPY-I-NETNOTWIREDand that FAL/DAP is "partial/real". Neither is true onorigin/main—decnet$task-to-task(which explicitly covers FAL) isabsentin the register,dcl_cmd_file.c'scmd_copy()has noNODE::handling at all (no NETNOTWIRED string exists anywhere in the codebase), anddecnetd.ccomments confirm object 17/FAL is "not built". The guide documents this honestly:COPYover DECnet does not work today, and the FAL/DAP oracle (docs/oracle/vax-copy-fal-dap.md) is ground truth for a future implementation, not a shipped feature.Test plan
