 | Parked | Why | Consumers | Soft path meanwhile |
 | --- | --- | --- | --- |
 | #12 SNMP compound-index / `key_format` (ascii) | Engine primitive — Schema tools exhausted | #231 `community_access` mops ascii vs snmp 0; trap-dest class | Lane B continues; leave #231 open as NO_HOLE consumer |
+| #298 get_snmp_config | Engine NO_HOLE — For SSH to meet gold (MOPS' 3 keys), the trap community from the already-cached `show snmp trap` would have to be merged into `community_access` and into every link of its 4-link lookup chain (`communities`, then `security_name`, then `group_name`, then `access`). Every link is keyed from `show snmp community`. Engine has no primitive that merges a key from a second show output into one dict attribute plus its chain, and `show snmp trap` carries no access token, so `ro` would be invented. Engine ask: a multi-command key merge with access class. SNMP=0 stays with #231. | #298 get_snmp_config | Next step: park Engine until HITL opens. |
+| #178 get_aca | HITL NO_HOLE — The `show config envm` labels and slot layout have never been captured, no sidecar catalog entry sends that command, and Tier1 direct capture isn't authorized. Live result: ssh selected_memory none / 0 slots vs mops/snmp sd / 2 slots. | #178 get_aca | Next step: reopens when a raw capture exists, then soft Schema candidate. |
 | TC-BITS (~3) prove-before-flip | Generator teach needs live prove first | #205 residual | Parked — not overnight flip |
 | MOPS/SNMP multi-field INDEX / singular `index_field` collapse | Driver `_list_to_dict` / compound INDEX — Schema cannot un-collapse | #68 get_software images; #106 MOPS multi-field INDEX; #12 SNMP compound | Soft hops elsewhere; park Engine |
 | SNMP inspect `last_oid` / walk heartbeat | Hang never returns; snmp call-timeout has no last_command (SSH-only today) | #47 get_interfaces snmp fanout (closed) | Schema walk fan-in first; park Engine heartbeat |
