High-fanout identity anchors (voice, writing-imprint, self-root) have ~670KB
neighborhoods. inspect_graph returned the full traversal, which overflowed the
MCP client's context and socket-closed the wrapper mid self-load -- the soul
could not traverse its own identity graph.
handle_api_inspect_graph gains an opt-in `compact` projection (compact=1|true):
the neighborhood is relevance-ranked, the top K (default 12) keep a UTF-8-safe
content snippet (default snip=600), and the remainder collapse to lightweight
{id,label,node_type,tier,edge,pointer:true} stubs. This bounds the voice node
from 669,799B -> 25,353B (HTTP 200, valid JSON) and the wrapper's soul-load no
longer socket-closes. New helpers: api_compact_neighbors, api_neigh_full,
api_neigh_pointer, api_neigh_rank, api_neigh_better, api_float_or.
The flag is gated: ABSENT it, the response is byte-identical to the old plain
traversal, so the studio app (which never sends it) is unaffected. The MCP
wrapper (mcp-wrapper/src/main.el) appends &compact=1 on its inspectGraph and
fetch-by-id paths.
dist/soul.c is REGENERATED so CI ships the fix: CI compiles the committed
single-TU dist/soul.c directly (running elb/elc on the Linux runner OOM-kills
it), so an .el-only change would build the OLD behavior. Regenerated and verified
on macOS -- compiles with the CI cc line (0 errors) and, on a throwaway soul over
a copy of the live snapshot, serves compact ~25KB / non-compact ~670KB. The regen
also syncs the amalgamation to this branch's .el sources, which had drifted
several self-review commits ahead of the previously-committed soul.c.
Docs: docs/architecture/00-05 added; 01/02/05 corrected so the relevance-ranked
inspect_graph projection reads as committed source, not an in-flight concern.
Two fixes, one found by making the other.
1. HEBBIAN WRITE-BACK. This daemon learned 1,198 associations in 23h48m and
kept none of them: it syncs FROM the engram server and never pushes, and
mem_save() is unreachable in HTTP mode by design (soul.el only sets
soul_snapshot_path inside `is_genesis && safe_to_seed`, false whenever
ENGRAM_URL is set, because the server owns persistence). So the one process
that runs idle cognition -- where essentially all co-activation happens -- was
the one process that could not remember what it learned.
hebb_consolidate() now drains the runtime's write-back queue on every heartbeat
and POSTs it as ONE batch to /api/edges/batch. One request, one durable write,
not one 60MB snapshot per edge. Also drains on clean shutdown, so an exit
between beats doesn't take the last 8 minutes of learning with it.
_auth is required and its absence is silent: check_auth_ok exempts GET and
/api/neuron/state-events (which is why ise_post works keyless) but gates every
other mutation on "_auth" in the BODY -- http_serve surfaces no headers, so
there is no Bearer path. An unauthorized reply is NON-EMPTY, so the obvious
`if resp == "" return 0` check would have reported delivery of edges that were
refused, after the drain had already destroyed them. Caught before it shipped.
Gauges hebb_wb_pending/_drained/_dropped/_sent go into the heartbeat so a
consolidation path that stops delivering is visible in the stream.
2. A READ ROUTE MUST NEVER WRITE THE CANONICAL SNAPSHOT. GET /api/graph/edges
serialized this process's graph straight over $HOME/.neuron/engram/snapshot.json
-- the engram SERVER's durable store -- and read the edges back out of it. I
triggered it myself this morning fetching edges for the census above:
snapshot.json went from the server's 41,213 edges to the soul's 42,431, and the
next engram restart loaded the soul's graph as canonical. It happened to be a
superset (Knowledge 1198->1218, Memory 1238->1242, no durable type down), so
nothing was lost. That was luck. Had the soul been running a partial load --
the exact failure soul.el's safe_to_seed guard exists to catch -- one GET would
have destroyed the store, with no write-side guard able to see it coming.
The engram server fixed this same class of bug on 2026-07-21 by routing exports
to a dotted sidecar; the soul kept the original pattern. Same fix: exports go to
.soul-edges-export.json. Also stops a 60MB serialize-and-reread per GET.
Verified: boot 26 loaded 42,432 edges with hebb_max 0.4941 carried across the
restart -- the first time this daemon has ever started knowing what it learned.
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.
