Phase 1 tombstoned memory/delete + node/delete, but the generic forget
path was still destructive. This routes every forget through the same
tombstone semantics so nothing in the daemon can hard-delete an engram
node anymore.
Canonical helper: mem_tombstone (memory.el, imported first so every module
can call it) — keep the node + its edges, record a Tombstone marker, never
engram_forget. neuron-api's tombstone_node now delegates to it (single
source of truth).
Per-path before -> after:
- memory.el `mem_forget` hard delete (engram_forget) -> tombstone. This
alone fixes both callers: the /api/neuron/memory/forget route
(handle_api_forget) and the cultivate op=="forget".
- awareness.el autonomous `forget` action engram_forget -> mem_tombstone.
The soul can no longer autonomously hard-delete a memory.
- mcp-wrapper tool_forget was a FAKE no-op that returned {"ok","deleted"}
without deleting OR tombstoning -> now routes to the soul's tombstoning
/api/neuron/memory/delete; tool description fixed to say it
supersedes/tombstones (recoverable), not "Remove a node".
Left intentionally as hard deletes (internal GC / lifecycle, not user
memory, all call engram_forget directly): session-summary replace
(chat.el), mem_consolidate dedup (memory.el), session-start telemetry
pruning (soul.el), session lifecycle (sessions.el).
Regenerated both ship paths under a 3GB physical-RSS watchdog (peak ~32MB):
dist/soul.c (single-TU amalgamation, macOS/Linux) and the per-module
dist/{memory,awareness,neuron-api}.c (Windows/Linux build). Verified: no
forget handler calls engram_forget; a forget leaves the node present +
tombstone marker. Gate (neuron-ui verify-soul-contract.sh, new memory-forget
row): PRESENCE + IMMUTABILITY PASS.
Regenerates the combined dist/soul.c and per-module dist/*.c from the current
El sources, on top of the elc-source-typo fixes (PR #77) and the Track B
threat-to-others routing (PR #76), both already on this branch.
Validated end to end under a physical-RSS watchdog (macOS silently ignores
ulimit -v / RLIMIT_AS, so every elc/elb run was RSS-polled and kill -9'd at a
3GB ceiling, one module at a time):
- OOM is GONE. The stale dist/soul-with-nlg.el (which still carries the
malformed string literals) explodes to 3.3GB+ and is watchdog-killed at ~90%.
With the typos fixed, every one of the 48 modules compiles at <=18MB peak RSS,
and the full flat amalgamation compiles as a single translation unit at ~68MB.
The 700GB pathology was purely the unbounded-parser-on-malformed-literal loop;
no malformed construct means no loop.
- The regenerated soul.c contains Track B: safety_classify_hard_bell ->
threat_other -> safety_hard_directive routes credible threat-to-others to 911
and explicitly NOT to 988 / the safety contact. Verified in source, in the
emitted C, and in the linked binary's strings. Track A (abuse / self_harm)
is unchanged and still checked first.
- The regenerated soul links to a working native arm64 binary and boots: serves
on a throwaway port, /health returns 200, awareness loop runs.
Also fixes one source blocker discovered during regen (unrelated to the typos
or Track B): chat.el handle_chat_agentic left a void `if { println(...) }` in
value position, which the current elc lowers to `_if_result = (println(...))`
(assigning void) -> invalid C. Bound an explicit Bool so the branch is
non-void; behavior unchanged (still only logs on persist failure).
NOTE (runtime dependency, for controlled deploy): this branch's chat.el calls
engram_get_node_by_label, which the canonical el-compiler/runtime does not yet
declare/define (the release runtime v1.0.0-20260501 has it; the newest runtime
has arena + http_serve_async but not this). Building the soul requires a runtime
that has all three. Land engram_get_node_by_label into the runtime package
before this soul.c can be built in CI.
Do not merge — regen + Track B going live is a controlled-deploy call.
- sessions.el: new sessions module with session management and approval gate
- routes.el: wire /api/sessions routes (list, get, create, approve, tool_result)
- chat.el: thread-aware activation — short messages anchor to last reply
before engram compilation so follow-ups stay on-topic
- chat.el: agentic path tracks per-session history (session_hist_{id})
instead of shared conv_history, seeding each turn with prior context
- chat.el: add call_neuron_mcp, dispatch_tool, is_builtin_tool, next_bridge_id
agentic_loop, bridge_save, agentic_resume, handle_tool_result
- dist/soul: rebuild with all of the above
neuron-api.el is a new first-class El module that implements all Neuron
cognitive API handlers natively — no HTTP round-trips, no MCP wrapper,
direct engram builtin calls. All capabilities that previously lived in
the MCP wrapper adapter now live here in the soul.
Handlers: begin_session, compile_ctx, remember, recall, search_knowledge,
browse_knowledge, capture_knowledge, evolve_knowledge, promote_knowledge,
browse_processes, define_process, log_state_event, list_state_events,
inspect_config, tune_config, inspect_graph, link_entities, list_typed,
consolidate.
Routes wired in routes.el under /api/neuron/* (GET + POST).
Also compiles all loop-1/loop-2 .el source changes into dist/*.c and
rebuilds the binary. memory.elh and neuron-api.elh updated with new exports.
elp-input.el: replace broken engram_search_json with engram_activate_json
as Layer 1. Layer 2 suppress/filter keeps nodes with non-zero salience/
importance. Reason step extracts patient from top activated node content.
ELP grammar realizes the response via generate().
routes.el: add 'elp' event_type to handle_dharma_recv so the studio can
route ELP requests through dharma.
