transduce() is now THE single mechanism: one function, no content-type
branch inside it. It never asks whether `source` is prose, JSON, or
raw/opaque bytes (audio, etc.) — it runs one algorithm unconditionally:
split on "\n\n" as a universal boundary-marker check, and if that finds
no boundary, fall back to fixed 4096-char windows. Same node/edge wiring
(root -contains-> chunk, chunk -precedes-> next, "#"-prefixed chunk gets
a heading/section_of link) regardless of what's inside a chunk. Dedup is
the existing find_existing_by_content path via merge_manifold, applied
uniformly. The old transduce_structured JSON dataset/records/feature-node
interpretation is deleted outright, not just unused — a JSON file now
gets chunked and deduped like anything else, with no pre-computed
structure. All five ingest_* entry points still exist unchanged in name
and role; ingest_file/ingest_dir/ingest_url/ingest_llm now call the one
transduce() (ingest_stream builds its own turn-nodes directly and never
called either old function, so it's untouched).
This unlocks raw/opaque content (audio, or anything else with no natural
text/JSON shape) without any DSP, LLM call, or external API: transduce()
chunks it exactly like it chunks anything else. There is zero semantic
understanding of audio (or any payload) claimed or built here — any
meaning is expected to emerge later from Neuron's own existing mechanisms
(embedding, spreading activation, dedup) acting on this real geometry
over time.
Two small C builtins added to el_runtime.c/h (fs_size, fs_read_b64_chunk)
because El strings are NUL-unsafe under strlen-based ops and fs_read()'s
result silently truncates at the first embedded NUL, which is routine in
real binary/audio bytes. ingest_file compares fs_read()'s string length
against a real fs_size() stat() count; on mismatch it rebuilds the
payload as base64-encoded fixed 3072-byte windows read directly off disk
(binary-safe in C, verbatim, no invention), joined with the same "\n\n"
marker transduce()'s boundary scan already looks for. This is a
mechanical fidelity fix, not interpretation of content — transduce()
never learns a fallback happened. Registered both builtins' arity in
codegen.el; did not rebuild the elc compiler binary itself (unrelated,
pre-existing gap: self-hosting elc via el_seed.c fails on this worktree
independent of this change, reproduced with codegen.el reverted) — the
existing elc binary compiles calls to unregistered builtins via its
already-existing arity=-1 passthrough, confirmed by an actual clean
`elc ingest.el` + `cc` build against the modified el_runtime.c.
INGEST_KIND keeps existing only as an acquisition-mechanism selector
(dir/file/url/llm/stream — which RPC to use to fetch bytes), not as a
content-type flag; the redundant "structured" value (an alias for "file"
that hinted the now-deleted JSON branch) is removed. ingest_dir drops its
file-extension filter for the same reason: transduce() takes anything now.
Verification: local manifold construction confirmed correct against a
real captured audio file (will_clean.wav, 304288 bytes, and a 12288-byte
real prefix slice) — exact expected node/edge counts both times
(101 nodes/199 edges full file; 5 nodes/7 edges for the slice, matching
ceil(bytes/3072)+1 nodes and 2n-1 edges), with real, verbatim base64
content confirmed decoding back to the actual WAV header bytes. Compiles
clean via the real elc + the modified el_runtime.c/engram_*.c (built and
booted an actual sandbox engram off this exact source with `nsbx create
--branch`).
NOT verified this session, disclosed rather than papered over: end-to-end
server-confirmed persistence (a real before/after /api/stats delta, and a
fetched node by id) for the audio, prose, and JSON-fixture cases. Every
local nsbx sandbox engram tried tonight (two stock pre-#109 binaries
hitting the known O(N*D) brute-force scan bug, then a fresh #109/HNSW
binary built from current dev) took minutes-to indefinitely long on the
final /api/load-merge write's embedding step and hit the client's 60s
HTTP timeout before responding, even for a 5-node write. This is
confirmed as real (if slow) forward progress, not a hang: the sandbox's
WAL file was observed growing steadily across every attempt. The code's
own pre-existing HONESTY GATE correctly refused to report success in
every case, returning "load-merge failed: ..." with a
"nothing below this manifold was confirmed persisted by the server" note
instead — exactly as designed. This is an environment/infrastructure
limitation, not a defect introduced by this change: the engram server
binary itself is untouched by this commit.
Will waived diff review -> build it for real. Add engram_boundary_beat() to the
runtime (afferent counter++ + engram_chrono_tick + engram_strengthen(self-anchor)
+ dharma_emit) and two act-stats counters (aff_boundary_ops, dharma_emits).
codegen cg_fn injects ONE engram_boundary_beat(op) at the entry of every
@manager/@accessor fn (fn_has_decorator, so it fires under @route @manager too) —
a decorated op self-reports with ZERO hand-written instrumentation. Rebuilt elc
self-host + the cognition engram in the worktree; ran it as the clone daemon on
:8900. Proof (/api/boundary-proof, @manager, empty body, 5x): aff_boundary_ops
0->5, dharma_emits 0->5, self activation_count 1510->1513, chrono stamp advanced.
Brought in feat/cognitive-architecture engram runtime+server for the build.
strengthen = activation bump (not content/edge write) -> identity protection
intact. Live :8742 untouched; no push, no cutover.
- Wire paged store into the ENGRAM SERVICE (server.el, the authoritative durable
owner): boot->engram_store_boot, persist_canonical->engram_store_checkpoint,
gated by ENGRAM_STORE.
- elc (lang/elc.c + src/parser.el + codegen.el + elc-combined.el): OOB guard in
tok_kind/tok_value + parse_block progress backstop — fixes the pre-existing
unbounded-memory fold hang on sessions.el.
- engram_prune_telemetry mirrors ISE prune to the store (store_forget) so store
live-count tracks resident and stale telemetry stays bounded.
- Deployed live 2026-08-12: engram :8742 on neuron.egm+WAL, count reconciled 11552.
Establish lang/runtime/ as the ONE canonical el runtime (from the active
runtime that carries hebb/emb persistence + the new WAL); repoint the el CI
publish, engram build, elb default, and in-repo build scripts to it; delete
the el-compiler/runtime + lang/releases/ forks; add scripts/check-single-runtime.sh
drift guard.
Fixes a live prod bug: the el CI published el-runtime-c/-h from the LAGGING
el-compiler fork (0 hebb refs), so the shipped soul never persisted Hebbian
edge weights — learned co-activation was wiped on every restart. Publishing
from canonical ships the stranded 'learning that cannot outlive the process'
fix.
WAL storage engine + integrity fixes (DELETE->tombstone + store-layer
protection, safe data-dir default) ride in behind ENGRAM_WAL (default off =
byte-identical to today). Verified: engram elb per-module build clean, WAL
gate 66/66, native smoke ok, drift-guard green.
