The soul obeys half of its own ownership rule. soul.el:571-573 says "when
ENGRAM_URL is set the HTTP Engram owns persistence — the soul must NEVER write
to the local snapshot", and it doesn't. But nothing was ever built to hand the
soul's writes TO that owner: sync is pull-only (/api/sync -> engram_load_merge),
so every node created inside the soul lived in process RAM and was shed on
restart. Measured live 2026-08-07: soul node_count=102184, engram 79197.
SCOPE CORRECTION vs the earlier internal spec: engram provisional claim 17's
"pull-then-push" is a PEER-ENGRAM to PEER-ENGRAM protocol (claims 15-18 say so
explicitly). The soul is a CALLER of the database API, not a peer. Claim 17 is
NOT authority for a soul<->engram contract and is no longer cited as such. The
design here follows from the ownership rule alone.
Mechanism: a new Accessor, persist.el, is the single boundary. Writes stage a
delta to a filesystem spool and are pushed to the owner via POST /api/load-merge
— NOT POST /api/nodes, which mints a new server-side id (breaking dedup and
edges) and drops label/tier/tags/importance/confidence (verified in a sandbox:
a tier "Canonical" probe came back "Working"). load-merge preserves the id and
every field, dedups nodes by id and edges by (from,to,relation) so retries are
no-ops, and calls persist_canonical() so THE OWNER writes its own file — the
ownership rule is honoured rather than worked around.
Spool-and-drain rather than push-per-write: measured ~0.38s per load-merge at
live scale (79k nodes/176MB), and a chat turn writes 5-7 nodes. The spool is on
disk, not in process state, because the soul serves each connection on its own
pthread and a shared buffer would lose entries to a read-modify-write race. That
also buys crash recovery: writes orphaned by kill -9 are drained on next boot.
Honesty: api_persisted (the gate all 10 MCP write handlers pass through) and
mem_store now assert AT THE OWNER instead of reading back the soul's own RAM.
With the owner down a write returns {"ok":false,"error":"write_not_persisted"}
and the delta is queued — where main returns {"ok":true} for a write that dies.
Coverage: 35 node sites + 9 edge sites routed through the boundary. Deliberately
excluded, with reasons in persist.el: 4 InternalStateEvent sites (Will's own
telemetry carve-out), the boot counter and the persona (both already have
bespoke owner-side write-backs), and soul.el's 54 genesis identity edges
(file-mode only). engram_strengthen and engram_forget are NOT propagated —
load-merge cannot update or delete, and hard-deleting at the owner would fail
verify-soul-contract.sh section B.
Also fixed here:
- routes.el GET /api/graph/edges engram_save()'d straight over the owner's
canonical snapshot.json — a read route, in a non-owner process, clobbering the
canonical on every call. Same defect class Will removed from the engram in el
dc39a61. Now exports to a scratch path. With this gone the soul writes nothing
at all in HTTP mode.
- persist.el must clear the runtime's _tl_fs_read_len hint after every fs_read.
In vendored runtime v1.0.0-20260501 that hint becomes the NEXT response's
Content-Length, so reading a spool file mid-request made an 86-byte reply go
out as 497 bytes with 411 bytes of adjacent heap trailing it. Caught and fixed
at our boundary; the runtime class was fixed upstream in el 43636ae, which is
not the pinned runtime here.
Rung: E2E-VERIFIED, discriminating. Same harness, same engram binary:
write-through: LEG 1 PRESENT at owner, LEG 2 SURVIVED kill -9 + restart
main: LEG 1 ABSENT at owner, LEG 2 LOST
verify-soul-contract.sh: GATE PASS on both builds (27/27 routes, immutability).

Saving the 988 crisis-line contact returned truncated, unparseable JSON —
cut mid-"set_at" at the file's byte length (e.g. 178 of a 218-byte
response). The contact written to disk was complete; only the HTTP response
was clipped, so a real customer's crisis-contact save came back corrupt.
Root cause is in the el runtime's response writer, not a handler buffer:
fs_read stores the file's byte count in a thread-local (_tl_fs_read_len)
for binary-safe file serving, and the response writer uses that length when
non-zero instead of strlen(body) (el_runtime.c:1409). Both safety-contact
handlers call fs_read (the POST read-back verify; the GET file read) and
then return a LONGER wrapped JSON string, so the response is capped to the
file size.
Soul-source fix (no runtime change needed):
- POST: verify persistence via fs_write's return (1 = all bytes written)
instead of an fs_read read-back — removes the fs_read, so nothing caps the
response.
- GET: fs_read is required, so reset the thread-local after it with a no-op
fs_read("") (fs_read zeroes the length before it opens a path) so the
wrapped response is sent in full.
Verified: POST (crisis-line + custom) and GET now return complete, valid
JSON (parses cleanly, full contact incl. set_at). Regenerated dist/soul.c +
dist/safety.c (3GB RSS watchdog, release el_runtime v1.0.0-20260501).
Full suite still green: verify-soul-contract GATE PASS (PRESENCE +
IMMUTABILITY), genesis boot survives (/health 200, no segfault), bounded-
persona floor still compiled in.
NOTE: the underlying runtime leak (any handler that fs_reads then returns a
longer string) is worth a proper fix in el_runtime.c (use the max of
strlen and _tl_fs_read_len) so this class can't recur.
Three unescaped-quote typos produced malformed El string literals that broke
compilation:
- safety.el:282 stray extra double-quote at the tail of safety_soft_phrases
(\"having a breakdown\""]") closed the string early, desyncing the lexer's
string/code phase for the rest of the file and shattering later apostrophe
text (can't, i'm) into bare identifiers -> invalid C.
- sessions.el:517 str_replace(topic_snip, """, ...) — the bare """ is an
empty string plus an unterminated string that swallowed the closing ) and };
with the current elc this triggers the parser overrun -> ~700GB OOM.
- sessions.el:520 unescaped nested quotes in the topic_tags literal.
All three now use escaped inner quotes. Verified: both files compile clean
under the current elc (safety.c and sessions.c well-formed, brace-balanced).
A homicide/assault threat (going to kill, going to hurt, etc.) had no
bucket in safety_classify_hard_bell and fell through to the self_harm
default, showing the user the 988 suicide line and (via the desktop gate)
their safety contact. That framing is wrong and potentially dangerous for
someone voicing intent to harm another person.
Add a distinct Track B (safety_threat_to_others_phrases + a threat_other
classification and a safety_hard_directive branch) that refuses to assist,
de-escalates, and directs to 911 for a credible imminent threat, and that
never surfaces 988 or involves the safety contact. Track A (abuse /
self_harm) is checked first and unchanged, so victim and self-directed
phrasings still route correctly.
Source-only change: requires a soul rebuild + dist/soul.c regen to ship.
- soul.el: fix state key bug in layered_cycle (conversation_history -> conv_history)
- safety.el: add indirect crisis location patterns to soft_bell phrase list
- soul.el: wire safety_augment_system into layered_cycle for soft_bell turns
- chat.el: load cross-session affective context at session start when distress signals found within 72h
