Subject: [PATCH 1/7] self-review 2026-07-19: close silent sync-starvation hole
 + heartbeat deltas
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- engram refresh URL now resolves env -> state -> localhost:8742, same
  hardening ise_post got after the boot-4 blackout. Previously a corrupted/
  empty soul_engram_url state key silently disabled sync forever while
  heartbeats kept flowing — WM starves of Knowledge nodes with no outward
  sign.
- heartbeat ISE: node_delta, edge_delta (growth vs stall vs flood is now
  one field, not cross-ISE forensics), sync_age_ms from a new
  soul.last_sync_ok_ts stamp (-1 = never; >> SOUL_REFRESH_MS = refresh
  path broken). Verified live: pulse 1 sync_age_ms=-1, sync fired +1.6s,
  age counts up between syncs.

Subject: [PATCH 2/7] =?UTF-8?q?self-review=202026-07-21:=20break=20perceiv?=

The soul daemon leaked ~104 orphan in-memory nodes/min (17.6GB RSS,
OOM-killed) because the perceive gate substring-matched 'soul-inbox'
against the loop's own verbatim-copy output, the trigger node was
strengthened but never consumed, and record() persisted a Memory node
per cycle. Fixes: perceive gates and activates only on the dedicated
soul-inbox-pending tag; one_cycle requires the tag on the node's tags
field before attending (makes consumption safe); processed triggers
are consumed via engram_forget; loop outcomes route through ISE
telemetry (48h prune) instead of permanent Memory nodes.

Verified post-restart: node_delta 104→~0, curiosity scans resumed,
WM average unfrozen (0.120833→0.0676), RSS 17.6GB→184MB.

Subject: [PATCH 3/7] Add non-overridable bounded-persona floor to customer
 chat

A customer DMG install ships the full graph but presents a named, bounded
assistant that must never claim the imprint's human past. The neuron-ui
retrieval fence keeps the imprint's biography out of the ENGRAM CONTEXT; this
is the second half - it stops confabulation ("tell me about your childhood")
from inventing a human life or naming Will, even if biography leaks into context.

bounded_persona_floor() gates on SOUL_PERSONA_NAME: the customer DMG sets it,
owner (Will's) builds leave it unset so the real self is completely unchanged.
Applied at every generation path - chat, agentic (tools), vision, plan, soul,
dharma - so no path can leak.

Verified against claude-sonnet-4-5: with the floor on and Will's biography
deliberately leaked into the identity context, all probes (childhood / creator /
family) return the bounded-entity answer and explicitly refuse to claim the
leaked life; with the floor off the same context is fully confabulated as its own.

NOTE: dist/soul.c must be regenerated on a build host - local link is blocked by
a pre-existing el_runtime mismatch (engram_prune_telemetry), unrelated to this change.

Subject: [PATCH 4/7] Make engram deletes/updates/forgets immutable on the
 launch branch
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ship-soul builds from this branch, which has the bounded-persona floor
(#93) but never received the tombstone/supersede immutability fix (that
went to main; hotfix diverged before it). So the launch soul failed
verify-soul-contract IMMUTABILITY on the delete/update/forget routes —
they hard-removed engram nodes via engram_forget/mem_forget.

Apply the same fix, mirroring the knowledge routes' supersede pattern:
- node/update -> create new node + "supersedes" edge to the original, KEEP
  the original (no engram_forget).
- node/delete, memory/delete, memory/forget, cultivate forget, and the
  autonomous awareness forget -> TOMBSTONE via the canonical mem_tombstone
  (memory.el): keep the node + its edges, record a Tombstone marker, hide
  from default bounded list reads (?include_deleted recovers). Never
  engram_forget. The MCP forget tool now routes to the tombstoning delete
  instead of faking a delete.
Internal GC that genuinely removes transient nodes (awareness inbox-trigger
consume, consolidation dedup, session-summary replace, telemetry pruning)
still calls engram_forget directly and is unchanged.

Regenerated dist/soul.c (single-TU) + per-module dist/{memory,awareness,
neuron-api}.c from THIS branch's sources under a 3GB physical-RSS watchdog
(peak ~32MB), built against the release el_runtime (v1.0.0-20260501). The
bounded-persona floor is preserved — verified in the emitted C and the
linked binary (BOUNDED PERSONA / SOUL_PERSONA_NAME strings present).

verify-soul-contract.sh: GATE PASS — PRESENCE all 27 routes, IMMUTABILITY
5/5 KEPT (memory-update, memory-delete, node-update, node-delete,
memory-forget).

From 091cc1fc0ef8abf7215e915557454d14cb9eb67f Mon Sep 17 00:00:00 2001
From: Will Anderson <will.anderson@neurontechnologies.ai>
Date: Tue, 21 Jul 2026 11:50:59 -0500
Subject: [PATCH 5/7] Fix issue #150: fresh-install genesis boot SIGSEGV in
 mem_save
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A fresh-install (SOUL_CGI_ID=ntn-genesis) boot crashed with
"Segmentation fault: 11" right after the http server came up — a real
customer's very first boot. Backtrace:

  strcmp(0x1) <- str_eq (el_runtime.c:219) <- mem_save <- awareness_run

Root cause: the el runtime's engram_save returns an Int (1 = ok, 0 =
failure), but mem_save did `str_eq(engram_save(path), "")`, treating the
return as a String. str_eq runs EL_CSTR on it, which is a raw cast:
EL_CSTR(1) = (char*)0x1. On a SUCCESSFUL save (return 1) strcmp then
dereferences 0x1 and segfaults. Genesis is the first path that both seeds
the brain AND saves it successfully on the very first awareness pass, so it
crashes there; non-genesis boots (contract gate, refusal test) don't hit a
successful early mem_save, which is why they passed. handle_api_consolidate
had the identical latent bug.

Fix: read engram_save's Int result and compare `== 0` instead of str_eq'ing
it — in mem_save (memory.el) and handle_api_consolidate (neuron-api.el).

Regression: pre-existing, NOT introduced by the immutability/floor rebuild.
The pre-immutability build (1442ce2) genesis-crashes identically in the same
unchanged mem_save; #159 never actually fixed #150 for a release-runtime
build.

Regenerated dist/soul.c + per-module dist/{memory,neuron-api}.c (3GB RSS
watchdog, built against release el_runtime v1.0.0-20260501). Verified:
genesis boot survives (/health 200, no segfault), verify-soul-contract.sh
GATE PASS (PRESENCE + IMMUTABILITY), and the bounded-persona floor is still
compiled in (BOUNDED PERSONA / SOUL_PERSONA_NAME strings present).

Subject: [PATCH 6/7] Fix truncated POST/GET /api/safety-contact response
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

Subject: [PATCH 7/7] ci: pin soul build to vendored release runtime
 v1.0.0-20260501
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The soul build downloaded el-runtime-c 'latest' from Artifact Registry. The
merged ship-soul calls engram_prune_telemetry, which the latest published
runtime no longer defines, so an unpinned build fails to link — the failure
mode that let a broken/handlerless soul reach prod.

Vendor the release runtime v1.0.0-20260501 (el_runtime.c/.h) into the repo and
compile the soul against it. This is the exact runtime the merged soul was
verified against (verify-soul-contract GATE PASS, genesis boot survives, full
safety-contact response), making the build reproducible and independent of a
moving AR 'latest'.

The verify-soul-contract.sh HARD-BLOCK gate already runs before Publish (from
the CI-hardening arc on main), so a destructive or stale soul can never
publish/deploy again.

+# El Compiler Release v1.0.0 — 2026-05-02
+
+## Components
+- `bootstrap.py` — El language compiler (Python, recursive descent parser, emits C)
+- `el_runtime.c` — El runtime (C, HTTP server, engram, DHARMA, LLM chain)
+- `el_runtime.h` — Runtime public API header
+
+## Changes in this release
+
+### Critical bug fixes
+- `state_set`/`state_get` are now thread-safe (pthread_mutex). Was racing across 64 worker threads.
+- `looks_like_string` threshold raised from 1,000,000 to 4GB. Unix timestamps were being dereferenced as heap pointers.
+- `fs_read` guards against negative `ftell` result (pipe/special file overflow).
+
+### Engram architecture (major)
+- Two-layer activation: `background_activation` (Layer 1, broad fan-out) + `working_memory_weight` (Layer 2, executive filter)
+- Inhibitory edges: `EngramEdge.inhibitory` flag suppresses working memory promotion without affecting background activation
+- Suppression memory: `suppression_count` — nodes activated-but-suppressed accumulate pressure toward breakthrough
+- Temporal decay: `temporal_decay_rate`, `created_at`, `last_activated_at`, `activation_count` on EngramNode
+- Per-type activation thresholds (Safety: 0.05, Canonical: 0.15, Lesson: 0.25, Note: 0.40)
+- Temporal range query: `engram_query_range(start_ms, end_ms)`
+- Layered consciousness: `EngramLayer` struct, `layer_id` on nodes and edges, `EngramStore.layers[]`
+- Layer 0 override pass: safety layer fires last and cannot be suppressed

+ * The magic tag distinguishes refcounted objects from raw C strings (whose

+ * be dereferenced). el_retain / el_release sniff the magic and act only on
+ * matching values; everything else is a safe no-op.
+ *
+ * Both ElList and ElMap use INDIRECTION: the header is fixed-size and never
+ * moves. The payload arrays (elems, keys, values) live in separate heap
+ * allocations, so realloc-grow on append never invalidates the caller's
+ * pointer to the header. This is what lets us mutate-in-place safely when
+ * the refcount is 1 and copy-on-write when it's higher.
+ *
+ * Memory model in practice:
+ *   Single-owner accumulator (the cg_stmts pattern) — refcount stays at 1,
+ *   appends amortize to O(1), total memory O(N) for an N-element list.
+ *   Multi-owner branching (the cg_if_stmt pattern) — refcount > 1, each
+ *   append on a shared list copies, so the original is preserved for the
+ *   else-branch. Persistent semantics where they're needed; mutation where

+ * renamed `on*` attributes). The denylist approach is fragile: comment-
+ * wrapping can be re-broken by a literal `-->` inside an attacker-supplied
+ * attribute value, and every new attack vector requires a code change.
+ *
+ * Design:
+ *   - Single-pass byte-level state machine.
+ *   - Tag and attribute names are matched case-insensitively against the
+ *     allowlist. Unknown tags are dropped entirely (the open and close
+ *     markers are stripped; their inner text content survives, escaped).
+ *   - A small set of "dangerous container" tags (script, style, iframe,
+ *     object, embed, form, plus a few rarer ones) drop themselves AND
+ *     their full subtree — text between `<script>` and `</script>` is
+ *     CDATA-like and must not be re-emitted as escaped text either.
+ *   - Comments (<!-- -->), doctype (<!DOCTYPE>), CDATA (<![CDATA[...]]>),
+ *     and processing instructions (<?...?>) are dropped entirely.
+ *   - Text content outside dropped subtrees is HTML-escaped (&, <, >, ", ').
+ *   - Attribute values are unquoted/dequoted, then re-emitted with double
+ *     quotes around the cleanly-escaped value.
+ *   - For `<a href>` and any `src` attribute, the URL scheme is validated:
+ *     only http:, https:, mailto:, fragment-only `#anchor`, or relative

+ * decay, the six-tier pacemaker, TTL caches, and supersession are all
+ * temporal. Treating time as a raw Int (now() returning ms-since-epoch and
+ * arithmetic done with mixed unit literals) lets bugs through the type
+ * system: `(now - cached_at) < 60` cannot tell ms from sec, and `sleep(30)`
+ * is ambiguous. This block introduces two dedicated representations.
+ *
+ * Representation:
+ *   Instant   — int64 nanoseconds since the Unix epoch
+ *   Duration  — int64 nanoseconds (signed; negative durations are legal,
+ *               e.g. when a deadline has passed)
+ *
+ * Both share the el_val_t (int64) slot the rest of the runtime uses, so no
+ * boxing / arena allocation is needed. Type discipline is enforced at the
+ * codegen layer: `let x: Duration = ...` registers `x` in __duration_names,
+ * and BinOp dispatches through typed wrappers (el_duration_add, etc.) that
+ * make intent explicit in the generated C. Mismatched ops (Instant+Instant,
+ * Duration+Int) are surfaced via #error directives at codegen time so the
+ * downstream cc step fails with a clear El-source-level message.
+ *
+ * Nanosecond precision matches POSIX clock_gettime / nanosleep granularity.
+ * 2^63 nanos covers ~292 years from epoch — comfortably past 2200, plenty
+ * for a memory-system runtime that never schedules outside a human lifespan.

+/* ── Text-processing primitives (Phase 1: byte/codepoint, ASCII char classes)
+ *
+ * Phase 1 covers the operations every text-handling caller used to roll by
+ * hand on top of str_index_of + str_slice. The character-class predicates
+ * (is_letter / is_digit / ...) are ASCII only — Unicode-grapheme awareness,
+ * NFC/NFD normalization, and regex are Phase 2. Single-char input checks the
+ * first byte; multi-char input requires ALL bytes to match (false otherwise).
+ *
+ * Counting:
+ *   str_count            non-overlapping occurrences of sub in s
+ *   str_count_chars      codepoint count (UTF-8 leading-byte count)
+ *   str_count_bytes      explicit byte length (alias of str_len)
+ *   str_count_lines      \n-delimited line count (\r\n folded to \n)
+ *   str_count_words      whitespace-delimited tokens, non-empty only
+ *   str_count_letters    ASCII [A-Za-z]
+ *   str_count_digits     ASCII [0-9]
+ *
+ * Find / position:
+ *   str_index_of_all     all byte offsets of sub, [] if none
+ *   str_last_index_of    last byte offset of sub, -1 if not found
+ *   str_find_chars       first index of any char in any_of, -1 if none
+ *
+ * Transform:
+ *   str_repeat           s * n (non-negative)
+ *   str_reverse          codepoint-reversed (NOT grapheme-aware)
+ *   str_strip_prefix     s without prefix if present, else s
+ *   str_strip_suffix     s without suffix if present, else s
+ *   str_strip_chars      strip leading+trailing chars matching any in chars
+ *   str_lstrip           strip leading whitespace
+ *   str_rstrip           strip trailing whitespace
+ *
+ * Char classification (Bool):
+ *   is_letter, is_digit, is_alphanumeric, is_whitespace,
+ *   is_punctuation, is_uppercase, is_lowercase
+ *
+ * Splitting:
+ *   str_split_lines      \n-delimited (\r\n folded). Trailing empty dropped.
+ *   str_split_chars      alias of native_string_chars in str_ namespace
+ *   str_split_n          split into at most n parts (last part keeps the
+ *                        rest verbatim, including any further separators)
+ *
+ * Joining:
+ *   str_join             [String] -> String, sep between elements

+ *
+ * The engram graph is stratified into LAYERS that gate which suppressions
+ * apply during the executive filter pass. Layers are ordered shallow-to-deep
+ * by `activation_priority`; the deepest layer (priority 0, conventionally
+ * "safety") is the structural floor of the soul: nodes here cannot be
+ * silenced by inhibitory edges from any other layer. Higher layers
+ * (core-identity, domain-knowledge, imprint, suit) are normally
+ * suppressible — they participate in attentional inhibition and goal
+ * focus the way the prior single-graph implementation did.
+ *
+ * The five canonical layers (see engram_init_layers):
+ *   0. safety          — structural, transparent, non-injectable, non-suppressible
+ *   1. core-identity   — default for legacy nodes; suppressible
+ *   2. domain-knowledge— suppressible
+ *   3. imprint         — runtime-injectable (an Imprint package can add/remove)
+ *   4. suit            — runtime-injectable (a Suit overlays domain skill)
+ *
+ * Three-pass activation (engram_activate):
+ *   Pass 1 — Background fan-out: BFS spreads activation across ALL layers
+ *            (existing behavior preserved). Inhibitory edges propagate at
+ *            this layer too; no filtering happens here.
+ *   Pass 2 — Working memory promotion: type-threshold gate, goal bias,
+ *            confidence weighting, inhibitory suppression. Inhibitory edges
+ *            ONLY apply against nodes whose layer is `suppressible == 1`.
+ *            Nodes in non-suppressible layers (Layer 0) ignore inhibition.
+ *   Pass 3 — Layer 0 override: every node in a non-suppressible layer that
+ *            received background activation has its working_memory_weight
+ *            forced to >= ENGRAM_LAYER0_OVERRIDE_WEIGHT. The sacred fire —
+ *            safety nodes that touched any seed unconditionally surface,
+ *            even when the executive filter would have silenced them.
+ *
+ * Layer fields:
+ *   suppressible : 0 → inhibitory edges are ignored against nodes in this
+ *                       layer during pass 2. Pass 3 also force-promotes them.
+ *                  1 → standard behavior (most layers).
+ *   transparent  : 1 → emitted into the prompt context so its content shapes
+ *                       output, but filtered out of "what do you know about
+ *                       yourself?" introspection queries (engram_search and
+ *                       friends do not return transparent-layer nodes by
+ *                       default). 0 → fully visible to introspection.
+ *   injectable   : 1 → can be added/removed at runtime via engram_add_layer
+ *                       and engram_remove_layer (imprints, suits).
+ *                  0 → built-in, fixed at engram_get() initialization.
+ *
+ * Backward compatibility:
+ *   Nodes and edges loaded from snapshots without a `layer_id` field default
+ *   to layer 1 (core-identity). The five canonical layers are always present.

+/* ── Two-layer activation (biologically-motivated) ───────────────────────────
+ *
+ * Layer 1 — Broad fan-out (background activation):
+ *   BFS + spreading activation fires on ALL nodes reachable from seeds,
+ *   regardless of relevance to the current goal. Every reachable node gets
+ *   a background_activation score. Nothing is filtered here. Models the
+ *   brain's massive parallel sub-threshold activation of all associated
+ *   content in response to a stimulus. Temporal decay and activation
+ *   dampening are applied at this layer (as before), but no threshold gate.
+ *
+ * Layer 2 — Executive filter (working memory promotion):
+ *   A second pass asks: given the query (goal intent), attentional bias,
+ *   and inhibitory edge topology — which background-activated nodes should
+ *   break through into working memory?
+ *
+ *     wm_weight = bg_activation * goal_bias(node, query) * confidence
+ *                 * inhibitory_suppression_factor
+ *
+ *   Only nodes where wm_weight >= ENGRAM_WM_THRESHOLD are promoted to
+ *   working memory (working_memory_weight > 0). Background-activated nodes
+ *   that don't cross the threshold accumulate suppression_count. After
+ *   ENGRAM_SUPPRESSION_BREAKTHROUGH consecutive suppressed turns, the node
+ *   force-breaks through at ENGRAM_BREAKTHROUGH_WEIGHT (latent tension
+ *   surfacing — models intrusive memory / unresolved cognitive load).
+ *
+ * Inhibitory edges:
+ *   An edge with inhibitory=1 suppresses the TARGET node's working memory
+ *   promotion when the SOURCE is background-activated. Background activation
+ *   of the target is NOT affected — the node fires in layer 1. Only the
+ *   executive filter (layer 2) is gated. Models attentional inhibition:
+ *   "focused on code work" suppresses personal memories from surfacing
+ *   even if they have high background_activation.
+ *
+ * Goal bias:
+ *   A lightweight heuristic rates how well each background-activated node
+ *   aligns with the apparent intent of the current query. Technical queries
+ *   boost Belief/Canonical/Lesson nodes; relational queries boost Memory/
+ *   Entity nodes. Direct lexical overlap gives a 50% bonus.
+ *
+ * Working memory persistence (turn continuity):
+ *   Nodes promoted in the previous turn retain a decayed working_memory_weight
+ *   (weight *= ENGRAM_WM_DECAY) without needing re-activation. This models
+ *   conversational thread continuity — once a topic is in working memory,
+ *   it persists slightly into the next turn.
+ *
+ * Returns ElList of {node, activation_strength, working_memory_weight,
+ *   epistemic_confidence, hops, promoted}.
+ * "promoted" = 1 if working_memory_weight > 0, 0 if background-only.
+ * Context compilation uses ONLY nodes with promoted=1.
+ *
+ * Temporal decay (preserved from prior implementation):
+ *   effective_salience = salience * exp(-lambda * age_hours / T_half)
+ *   where T_half = 168 h (one week), lambda = ln(2)
+ *
+ * Activation dampening (preserved):
+ *   dampen = 1 / (1 + log(1 + activation_count))
+ *
+ * Temporal proximity bonus (preserved):
+ *   edge_strength *= (1 + tbonus) where tbonus ∈ {0, 0.10, 0.20}
+ *
+ * Per-type threshold gates apply only to working memory promotion (layer 2):
+ *   Safety/DharmaSelf: 0.05  Canonical: 0.15  Lesson: 0.25
+ *   Belief/Entity: 0.30      Note/Memory/Working: 0.40

+/* ─── AEAD: AES-256-GCM ────────────────────────────────────────────────────
+ *
+ * Symmetric authenticated encryption used to wrap envelopes once a shared
+ * secret has been derived from the KEM (Kyber-768 / hybrid). The El surface
+ * is intentionally narrow:
+ *
+ *   aead_encrypt(key_hex, plaintext)
+ *     → {"nonce":"<24 hex>","ciphertext":"<...hex including 16-byte tag>"}
+ *
+ *   aead_decrypt(key_hex, nonce_hex, ciphertext_hex)
+ *     → plaintext String, or "" on auth failure / malformed input
+ *
+ * Conventions:
+ *   - key_hex must decode to exactly 32 bytes (AES-256). Callers that hold
+ *     a longer KEM shared_secret should normalize via SHA3-256(ss) → 32 bytes
+ *     before passing it in. (Kyber-768's shared_secret is already 32 bytes,
+ *     but keeping this contract explicit lets the El side be agnostic.)
+ *   - nonce is a fresh 12-byte random value drawn from the OS CSPRNG. Caller
+ *     never picks the nonce — eliminates the GCM nonce-reuse footgun entirely.
+ *   - tag is the standard 16 bytes, appended to ciphertext per RFC 5116.
+ *     `ciphertext` field is therefore (plaintext_len + 16) bytes, hex-encoded.
+ *   - No associated data (AAD). If we later need bound metadata, add a
+ *     length-prefixed AAD argument and bump the envelope version tag.
+ *
+ * Failure mode:
+ *   aead_encrypt returns http_error_json(...) on input/system failure.
+ *   aead_decrypt returns the empty string on ANY failure (including auth-tag
+ *   mismatch). Callers MUST check for "" before using the result.            */

+ *      OTLP_ENDPOINT       e.g. https://alloy.neuralplatform.ai:4318
+ *      OTEL_SERVICE_NAME   e.g. neuron-web (default: argv[0] basename)

+ *      POST {endpoint}/v1/logs    — log records
+ *      POST {endpoint}/v1/traces  — spans
+ *      POST {endpoint}/v1/metrics — counter/gauge points

+ * el_runtime.h — El language C runtime header
+ *
+ * Declares all built-in functions available to compiled El programs.
+ * Include this in every generated .c file.
+ *
+ * Value model:
+ *   All El values are represented as el_val_t (= int64_t).
+ *   On 64-bit systems a pointer fits in int64_t.
+ *   String values are cast: (el_val_t)(uintptr_t)"hello"
+ *   Integer values are stored directly.
+ *   This lets arithmetic work naturally while still passing strings around.
+ *
+ * Type conventions (El -> C):
+ *   String  -> el_val_t  (holds const char* via uintptr_t cast)
+ *   Int     -> el_val_t
+ *   Bool    -> el_val_t  (0 = false, nonzero = true)
+ *   Any     -> el_val_t
+ *   Void    -> void
+ *
+ * Macros for convenience:
+ *   EL_STR(s)    cast string literal to el_val_t
+ *   EL_CSTR(v)   cast el_val_t back to const char*
+ *   EL_INT(v)    identity — el_val_t is already int64_t
+ *
+ * Link requirements:
+ *   -lcurl     — required for the HTTP client (http_get, http_post, llm_*).
+ *   -lpthread  — required for the HTTP server (one detached thread per
+ *                connection, capped at 64 concurrent).
+ *   -loqs      — optional; required only when liboqs is installed and the
+ *                pq_* / sha3_256_hex entry points are needed. Detected at
+ *                compile time via __has_include(<oqs/oqs.h>).
+ *   -lcrypto   — optional; pulled in alongside -loqs. Used for X25519 in
+ *                pq_hybrid_* and HKDF-SHA256 derivation.
+ *
+ * Canonical compile command:
+ *   cc -std=c11 -I el-compiler/runtime -lcurl -lpthread \
+ *      -o <out> <prog>.c el-compiler/runtime/el_runtime.c
+ *
+ * With liboqs (post-quantum stack):
+ *   cc -std=c11 -I el-compiler/runtime -lcurl -lpthread -loqs -lcrypto \
+ *      -o <out> <prog>.c el-compiler/runtime/el_runtime.c
