- engram_compile: BellEvent nodes do not carry created_at in the engram
node JSON; extract the unix timestamp from the embedded ' | ts:NNNNN'
pattern in the content string instead. Fall back to created_at/updated_at
if the marker is absent. Guard str_to_int against empty string so the 72h
recency check never silently treats every node as epoch-0 stale.
- auto_persist: append the current unix timestamp to the BellEvent label
('bell:soft:1749876543') to make it unique per turn. The previous label
('bell:soft') was the same for every soft bell, causing engram to treat
all subsequent writes as updates to the same node.
- auto_persist: detect bell level (soft/hard) on every user message using
safety_detect_bell_level; write a dedicated BellEvent engram node with
calibrated salience alongside the Conversation node when a bell fires.
Tag the Conversation node with bell:soft/bell:hard and 'affective' for
direct discovery without scanning all chat nodes.
- auto_persist: track per-session bell count, dominant level, and last
signal in state (session_bell_count/level/signal keys) so downstream
functions can act on the emotional history without re-scanning engram.
- engram_compile: include the top-1 most recent BellEvent node within 72h
in every context build. Distress context from earlier turns (same or
recent session) automatically travels into all subsequent LLM calls.
- hist_trim_with_bell_guard: replace hist_trim at the handle_chat call site.
Before evicting the oldest turn from the 20-turn window, inspect the user
message for bell signals. If a bell was present, write a preservation
BellEvent to engram before dropping the turn so the full message survives
the rolling window.
- session_hist_save: after writing the history node, check session bell
counters. On the first save where bell_count > 0, write a
session:emotional-summary BellEvent node with distress signal, count,
and dominant level. A state flag prevents duplicate writes on subsequent
saves in the same session.
