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.
