1. parse_salience_100: handle 3+ decimal digit salience strings correctly.
The two-branch 'else { stripped }' case treated any N-digit decimal value
as hundredths, so "0.125" (stripped=125) clamped to 100 instead of 12.
Now divides by 10^(N-2) for N>2, mapping "0.125"->12, "0.375"->37, etc.
2. mem_consolidate Canonical scan: replaced single engram_scan_nodes_json(50,0)
call with a paginated loop (page_size=50, advancing offset) so Canonical nodes
beyond index 50 are no longer silently excluded from the periodic boost.
3. mem_consolidate Canonical strengthening: add salience ceiling guard so nodes
already at the runtime maximum (serialised as "1" by %g) are skipped. Prevents
monotonic unbounded salience growth across successive consolidation passes.
4. soul.el affective cutoff: replaced json_get(aff_node, "ts") with
json_get(aff_node, "created_at") / "updated_at" fallback, consistent with
handle_chat. The old "ts" field is not a standard engram node field; missing
it caused the fallback to ts_now (always passes cutoff), over-including stale
nodes. New behaviour defaults to 0 on missing timestamps (conservative exclude).
5. History byte-cap: implemented the existing TODO 32KB byte-cap. Added
hist_trim_to_byte_cap() and applied it after count-based trim in both
handle_chat and handle_chat_agentic. Prevents 100KB+ state entries at 40 turns
during long technical sessions with large assistant responses.
Fix critical float parsing bug in engram_score_node: str_replace('.','')
then str_to_int silently miscored single-decimal salience strings (0.9->9,
0.7->7, 1.0->1). Introduce parse_salience_100() which detects decimal
position and scales correctly (no decimal: *100; one decimal: *10;
two decimals: as-is).
Replace flat 30-day linear decay with tier-aware decay curves: Canonical
nodes use a 365-day window (foundational identity resists aging), Episodic
nodes use 90 days, Working/untiered keep the existing 30-day slope. Floor
stays at 10 for all tiers.
Use max(created_at, updated_at) as the recency reference so revised nodes
are not penalised for their original creation date.
Extend affective context windows from 72h/7d to 14 days across all three
paths (engram_compile, handle_chat, soul.el load_identity_context) so a
Friday crisis carries into Monday sessions and all paths present consistent
context. The 72h/7d split caused conflicting affective context between
soul.el (which loaded a 5-day-old crisis node) and chat.el (which excluded
it on subsequent turns).
Add salience evolution to mem_consolidate: strengthen top working-memory
nodes (recently recalled across sessions) and Canonical-tier nodes
(foundational identity must not decay to the floor). Previously consolidate
returned structural counts only with no salience changes.
Expand conversation window from 20 to 40 turns in both handle_chat and the
agentic history trim. Long technical sessions were losing early problem
framing at 10 user + 10 assistant pairs.
Every engram_node_full call that dropped its return value now binds it
and emits a println on empty string. engram_save calls in consolidate,
heartbeat, and dharma-room-turn are checked for failure. The two API
handlers (log_state_event, tune_config) that skipped api_persisted()
now match the read-back-after-write contract used everywhere else in
neuron-api.el.
Files changed:
- chat.el: conv_history_persist, handle_dharma_room_turn, auto_persist
- soul.el: emit_session_start_event, seed_persona_from_env HTTP check
- memory.el: mem_save, mem_boot_count_inc
- neuron-api.el: handle_api_log_state_event, handle_api_tune_config,
handle_api_consolidate (engram_save + session summary write)
- awareness.el: ise_post local-engram fallback path
TODO comments added for non-atomic patterns (issues #12, #13) and
the missing circuit breaker (#14) — these require new primitives.
Routes a new event_type "chat_as_soul" through dharma/recv. The Studio
preassembles the system_prompt + transcript and dispatches per-speaker;
the soul-binary just performs the LLM call as the requested speaker_slug.
No engram_compile here — each soul has its own engram (88xx) and the
Studio queries it before composing the prompt.
Also: track the previously-untracked split source modules (chat, routes,
memory, awareness, studio) and add build.sh so the binary can be rebuilt
without the studio’s concat trick. elb resolves the import graph and
emits one .c per .el; we link them together with cc. dist/soul-el now
points at dist/neuron via symlink (matching the launchctl plist).
