1// nx_elara_state.nx -- F975 rung 1: the COMPANION STATE-COHERENCE ENGINE.
2//
3// THE KEYSTONE (operator charter 2026-07-23): "she DRESSES HERSELF UP and KEEPS herself dressed ... a
4// synthetic human ... with LOGICAL CONSISTENCY based on her INTERNAL THOUGHT PROCESS ... who FLOWS
5// THROUGH THE DAY, not scene to scene or clip to clip." That is only possible if ONE state store holds
6// her wardrobe/mood/location/arousal/energy/arc/dynamic and the chat persona + the gen prompt composer +
7// the wardrobe logic ALL read AND write it. Without it, "she stays dressed" is per-image luck; with it,
8// consistency is BY CONSTRUCTION -- what she SAYS == what she WEARS == where she IS, across turns.
9//
10// This is rung 1: PERSISTENT, AGENT-WRITABLE current state on the sovereign seg-store, MCP-exposed.
11// Each `set` also appends to a per-session TIMELINE (append-only, real-clock stamped) so rung 2 (F920
12// idle day-arcs / dream-cycle advancing state between interactions) has the substrate to flow over.
13// NOT gen: no image is produced here -- this is the mind's state, which the (GPU-gated) gen path reads.
14//
15// OO/SCALE: state is CID-keyed NXR1 records on nx_seg_store via nx_registry (last-write-wins per key,
16// O(log) get, additive history). Composes proven organs; introduces no new storage format.
17//
18// VERBS
19//   get <session>                     -> JSON of every state field (charter defaults for unset ones)
20//   set <session> <field> <value>     -> update one field (validated field name) + timeline append
21//   dress <session> <outfit_key> [loc] -> set outfit (+ location) THROUGH the elaragram- rules: refuses
22//                                        an unknown outfit, and (if loc given) flags an exposure-ceiling
23//                                        conflict -- the "keep herself dressed appropriately" primitive
24//   timeline <session> [max]          -> the flowing-day log, newest last
25//   selftest                          -> gate, verdict=GREEN|RED
26//
27// FIELDS (charter-derived, the only settable names): outfit location mood arousal energy activity
28// arc_stage dynamic. `dynamic` = the reversible relational stance (e.g. submissive|dominant|switch) so a
29// companion can act sub while the operator acts domme, or the reverse, per companion.
30// license_tier: ORIGINAL   No hw writes (Rule 26).
