ci: retrigger — prior run (6722) was killed mid-flight by a concurrent runner restart, not a real failure

The dist/soul.c-matches-sources check is a proof-of-concept of the DHARMA
contract, not an enforced gate we need between us mid-cultivation. Keep it
running (it still reports) but stop it failing the build. The enforced
contract is for the world and re-hardens before deploy, when the full DHARMA
blockchain stands up.

+//
+// WHAT THIS IMPLEMENTS
+//   The CGI provisional, 05-detailed-description.md, "Stage 1: Structural audit
+//   430". Verbatim, the audit module evaluates: the density and typed
+//   distribution of causal edges; the consistency between value nodes and
+//   execution-record neighborhoods; the richness and connectivity of the
+//   self-model; and the authenticity of open-question nodes in the wonder
+//   manifest. It "produces a coherence assessment 432 — NOT A BINARY SCORE but
+//   an annotated characterization of the graph's structural properties".
+//
+//   That last clause is the whole shape of this handler. Every finding carries
+//   its own numbers AND a plain-language note saying what the numbers mean and
+//   how they were obtained. There is no pass/fail, no percentage-of-health, no
+//   composite score, and `"score":null` is emitted explicitly so a downstream
+//   reader cannot mistake its absence for an omission.
+//
+// WHY IT EXISTS NOW, AND WHY THE FIRST FINDING IS THE ONE IT IS
+//   `runStructuralAudit` has been an advertised MCP tool with nothing behind it:
+//   the dispatcher GET'd /session/begin and returned that blob (mcp-wrapper/src/
+//   main.el). Meanwhile the failure the audit would have caught ran silently for
+//   about three weeks — the soul reported 103,089 nodes while the engram, which
+//   OWNS persistence, held ~79,900; a crash discarded the difference. Every boot
+//   reported green throughout, because nothing in the system ever compared the
+//   two sides. So finding 1 is owner-versus-runtime divergence: it is the check
+//   whose absence cost real memory, and it is cheap and exact.
+//
+// WHAT IS DELIBERATELY NOT HERE (stage 1b, see the `deferred` array in the
+// response): value/execution-record consistency and wonder-manifest
+// authenticity. Both need node types that barely exist in this graph today —
+// the response MEASURES those populations and reports the counts as the reason,

+//   index — `engram_find_node_index` is a linear scan over every node, so an
+//   exhaustive dangling check is O(nodes x edges) (~2.2e9 string compares at
+//   today's scale, tens of seconds inside one request). The samples are UNIFORM

+//   emitted with its own `sampled` / `population` fields plus an extrapolation
+//   labelled as such. Raise `?edge_sample=` / `?node_sample=` to the population
+//   size to run either check exhaustively and pay the time. The real fix is an
+//   id index in the runtime; that is the engram repo's, not this handler's.

+// persist.el — the soul→engram WRITE-THROUGH boundary (neuron#117).
+//
+// WHY THIS FILE EXISTS
+//   soul.el:571-573 states the ownership rule: "when ENGRAM_URL is set the HTTP
+//   Engram owns persistence — the soul must NEVER write to the local snapshot
+//   (not the persistence owner)." The soul obeys the NEGATIVE half. The POSITIVE
+//   half — how a write made inside the soul actually REACHES the owner — was
+//   never built. Sync is pull-only (awareness.el `/api/sync` -> engram_load_merge),
+//   so every node the soul creates lives in its process RAM and is shed on
+//   restart. Measured live 2026-08-07: soul node_count=102184, engram
+//   node_count=79197 — ~23k nodes existing nowhere but RAM.
+//
+// SCOPE NOTE ON THE PATENT (corrects an earlier internal reading)
+//   Engram provisional claims 15-18 describe a delta-sync protocol "with peer
+//   Engram instances"; claim 17's pull-then-push sequence is PEER-ENGRAM to
+//   PEER-ENGRAM. The soul is NOT a peer Engram — it is a CALLER of the database
+//   system API (cf. claim 27, "invoked explicitly by a caller of the database
+//   system API"). So claim 17 does not specify a soul↔engram contract and is not
+//   cited as authority here. This design is derived from the ownership rule
+//   alone: the owner owns the writes, therefore the soul must HAND writes to the
+//   owner and must never write the owner's file itself.
+//
+// THE MECHANISM, AND WHY NOT `POST /api/nodes`
+//   The obvious route is the one the persona/boot-counter write-backs already
+//   use, POST /api/nodes. It is the wrong instrument here, verified against the
+//   live engram binary in a sandbox:
+//     - it mints a NEW server-side id (engram_node), so the soul's id and the
+//       owner's id diverge — the next /api/sync pull re-imports the node as a
+//       DUPLICATE, and any edge referencing the soul's id never resolves;
+//     - it accepts only {content, node_type, salience} and drops label, tier,
+//       tags, importance, confidence, metadata. A probe posted with tier
+//       "Canonical" came back tier "Working", importance 0.5.
+//   POST /api/load-merge (Will's own route, el `dc39a61`) is the right one:
+//     - engram_load_merge PRESERVES the id and every field;
+//     - it dedups nodes by id and edges by (from_id,to_id,relation), so a
+//       re-submitted delta is a NO-OP — retry safety is free, and it is the same
+//       local-wins semantics the graph already uses;
+//     - it calls persist_canonical() — THE OWNER writes its own canonical file.
+//       The soul never touches it. The ownership rule is honoured in its
+//       strongest form rather than worked around;
+//     - it returns real counts {ok, nodes_added, edges_added, node_count},
+//       so a receipt can be a MEASUREMENT instead of a fixed success shape.
+//
+// SPOOL-AND-DRAIN, AND WHY IT IS NOT JUST A DIRECT POST
+//   Measured in a sandbox against a 79k-node / 176MB graph (live scale): one
+//   load-merge costs ~0.38s, essentially all of it the owner's persist_canonical.
+//   A chat turn writes 5-7 nodes; pushing each separately would add ~2.7s per
+//   turn. So writes are STAGED and pushed in one coalesced batch.
+//   The staging buffer is the FILESYSTEM, not process state, because the soul
+//   serves each HTTP connection on its own pthread (el_runtime http_serve_async)
+//   and a shared in-process buffer would lose entries to a read-modify-write
+//   race — silently, which is the one failure mode this file exists to end.
+//   One file per write, named with uuid_v4, is race-free by construction and
+//   buys a property a memory buffer cannot: writes that could not be pushed
+//   SURVIVE A SOUL CRASH and are drained on the next boot.
+//
+// WHAT IS DELIBERATELY NOT PUSHED
+//   - InternalStateEvent / heartbeat telemetry. Will's own carve-out, stated in
+//     engram server.el 8f8ccc9: "48h-pruned, loss-tolerant, ~2/min; snapshotting
+//     28MB per heartbeat is waste."
+//   NOTE (ours, flagged for Will): we do NOT additionally exclude Working-tier
+//   nodes. That exclusion exists in `fb0bb55` to stop the boot counter leaking
+//   through the /api/sync PULL; it is about sync backflow, not durability.
+//   Applying it here would exclude mem_store — which writes tier "Working" — and
+//   mem_store is the single most important durable write path in the soul. Boot
+//   seeding reads the canonical file wholesale, so a pushed Working-tier node
+//   does survive restart. This is the one classification call this file makes
+//   that Will has not ruled on.
+//
+// WHAT THIS BOUNDARY CANNOT EXPRESS (by construction, not by omission)
+//   - engram_strengthen (salience/activation drift): load-merge SKIPS ids that
+//     already exist, so it cannot update an existing node. There is no owner-side
+//     update/upsert route. Not pushable through any current route; left as a
+//     follow-up that needs a change in the engram repo.
+//   - engram_forget (hard delete): load-merge is additive and has no delete verb.
+//     Propagating deletes would mean DELETE /api/nodes/<id>, a HARD delete at the
+//     owner — which scripts/verify-soul-contract.sh section B explicitly fails the
+//     build for ("to delete is to supersede/tombstone, never hard-remove"). Local
+//     deletes therefore stay local; the TOMBSTONE NODE and its "tombstones" edge
+//     (mem_tombstone) are pushed, and that is the sanctioned representation of a
+//     deletion in this graph.

+# THE PROBLEM THIS CLOSES: until now, deploys were built by build-soul.sh, which
+# compiles a scratch amalgam and never touches dist/soul.c. CI compiles dist/soul.c.
+# Two lineages. On 2026-08-09 the committed input fell 2,761 bytes behind the sources
+# while three binaries built the other way were installed on the operator machine —
+# so "what runs" and "what the repo says builds" were different artifacts again,
+# which is the whole of #133 and #111 wearing new clothes.
+#
+# This builds from dist/soul.c with CI's own flags, after asserting that dist/soul.c
+# actually matches the .el sources, and writes a provenance sidecar so a deployer can
+# refuse anything of unknown origin.
+#
+# -rdynamic and -DHAVE_CURL are copied from .gitea/workflows/ci.yaml deliberately.

+# soulc-stamp.sh — make it impossible for dist/soul.c to drift from the sources
+# in silence.
+#
+# THE PROBLEM (neuron#133, and its own words): "Nothing in the tree regenerates
+# this file. Only a human running the recipe. It lags in batches, never
+# per-change, and it will drift again."
+#
+# It drifted. On 2026-08-07 a CI or GKE build off main would have shipped an
+# engine with NONE of five merged fixes — including a P0 safety fix — while
+# main's source read as correct. CI compiles dist/soul.c, not the .el files, so
+# the source being right is not the same as the build being right.
+#
+# WHY A STAMP AND NOT AUTO-REGENERATION: the CI workflow says elc cannot run on
+# the runner ("elb on Linux would OOM the runner (elc uses 24GB+ virtual memory
+# on a 16GB host)"). So the build cannot regenerate the file itself. What it CAN
+# do, for free and with no compiler, is refuse to compile a stale one.
+#
+# The stamp records a fingerprint of every .el source that feeds the amalgam at
+# the moment it was generated. --check recomputes and compares. Divergence is a
+# build failure with the recipe in the message, not a silent ship.
