The ship-soul builds from this branch, which has the bounded-persona floor
(#93) but never received the tombstone/supersede immutability fix (that
went to main; hotfix diverged before it). So the launch soul failed
verify-soul-contract IMMUTABILITY on the delete/update/forget routes —
they hard-removed engram nodes via engram_forget/mem_forget.
Apply the same fix, mirroring the knowledge routes' supersede pattern:
- node/update -> create new node + "supersedes" edge to the original, KEEP
the original (no engram_forget).
- node/delete, memory/delete, memory/forget, cultivate forget, and the
autonomous awareness forget -> TOMBSTONE via the canonical mem_tombstone
(memory.el): keep the node + its edges, record a Tombstone marker, hide
from default bounded list reads (?include_deleted recovers). Never
engram_forget. The MCP forget tool now routes to the tombstoning delete
instead of faking a delete.
Internal GC that genuinely removes transient nodes (awareness inbox-trigger
consume, consolidation dedup, session-summary replace, telemetry pruning)
still calls engram_forget directly and is unchanged.
Regenerated dist/soul.c (single-TU) + per-module dist/{memory,awareness,
neuron-api}.c from THIS branch's sources under a 3GB physical-RSS watchdog
(peak ~32MB), built against the release el_runtime (v1.0.0-20260501). The
bounded-persona floor is preserved — verified in the emitted C and the
linked binary (BOUNDED PERSONA / SOUL_PERSONA_NAME strings present).
verify-soul-contract.sh: GATE PASS — PRESENCE all 27 routes, IMMUTABILITY
5/5 KEPT (memory-update, memory-delete, node-update, node-delete,
memory-forget).
- 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
Block evolve_knowledge, evolve_memory, forget, and link_entities (to_id
direction) from modifying the 15 hardcoded identity and values node IDs.
Returns HTTP 403 with a hint to use the cultivation path instead.
Add POST /api/neuron/cultivate — the bypass endpoint for intentional
cultivation sessions. Accepts { "operation": "...", ...args } and performs
the same operations without the protection check.
Add handle_api_forget and handle_api_evolve_memory as new protected-by-
default handlers, routed at /api/neuron/memory/forget and
/api/neuron/memory/evolve respectively.
Tested: 10 verification cases — 403 on all blocked targets, 200 on
non-protected nodes and FROM-direction links, cultivate bypass confirmed.
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.
