Merge pull request 'Tools + agentic loop on the OpenAI wire — plus two pre-existing bugs that silently break chat' (#122) from feat/soul-openai-tools-v2 into main

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.

+# PORT-NOTES — openai tools port working state (2026-08-06, session handoff-safe)
+
+Spec: `docs/specs/SPEC-soul-openai-tools-v2-2026-08-06.md` (Tim-approved 2026-08-06). Tasks #1-5
+tracked in-session (1 ✓ wiring verdict, 2 ✓ stub rig, 3 in-progress = THIS, 4-5 pending).
+Worktree: HERE (`_wt-openai-tools`, branch `feat/soul-openai-tools-v2` @ dba755d). Round-9 trees
+READ-ONLY. Nothing committed yet.
+
+## Step-0 verdict (evidence in journal note ncli-653ba964dd76)
+Shipped app never wires the v1 lane: launcher exports `SOUL_LLM_MODEL/PROVIDER/BASE_URL` +
+`ANTHROPIC_API_KEY`+`SOUL_API_KEY` (= Keychain key for WHATEVER provider; installer/macos/
+neuron-daemons.sh:288-300 on hotfix/beta-round9); brain reads only SOUL_LLM_MODEL (chat.el:8) and
+NEURON_LLM_0_* (chat.el:1768-1794) which nothing sets. `/api/config` PATCH ignores llm_* fields
+(studio.el:36 handle_config: POST-only, reads model/provider/api_key only).
+**Bridge = brain-side ONLY (zero app-repo edits, zero round-9 collision):**
+- `llm_base_url()`: NEURON_LLM_0_URL → fallback SOUL_LLM_BASE_URL when SOUL_LLM_PROVIDER ∉ {"","anthropic"}
+- `llm_wire_format()`: NEURON_LLM_0_FORMAT → fallback derive from SOUL_LLM_PROVIDER (openai/grok/gemini/groq/ollama → "openai"; else "anthropic")
+- `agentic_api_key()`: already works (ANTHROPIC_API_KEY carries the provider key); add NEURON_LLM_0_KEY → SOUL_API_KEY fallback.
+
+## Design pins (stub asserts these — stub is green 58/58, tests/gate-openai/)
+- Request MUST send `"tool_choice":"auto"` (string) + `"parallel_tool_calls":false` explicitly.
+- `arguments` in tool_calls = JSON-ENCODED STRING; decode ONCE via json_get → feed dispatch_tool
+  verbatim. Stub's echo-mismatch check catches double-encode/decode (two-escaper trap).
+- Assistant echo turn: `{"role":"assistant","content":null,"tool_calls":[...]}` VERBATIM from response.
+- Feedback: `{"role":"tool","tool_call_id":"<id>","content":"<result string>"}`.
+- Resume must NOT re-answer an answered id (stub 400s on repeat tool_call_id).
+- Parallel tool_calls in a response: take FIRST only + log skip (mirror ADR-0005 stopgap); stub
+  scenario `parallel` proves behavior.
+- No tools in request when tools array empty/absent turns (boot probes) — stub defaults tolerate.
+
+## el idioms confirmed (from openai_chat_complete :1808-1854 + agentic_loop :2751-2838)
+- JSON: `json_get(s,k)` decoded string · `json_get_raw(s,k)` raw subtree · `json_array_len` ·
+  `json_array_get(arr,i)` · build by string concat + `json_escape()` (:1797, OpenAI-lane escaper).
+- HTTP: `let h: Map = {}` + `map_set(h,k,v)` + `http_post_with_headers(url, body, h)`;
+  Bearer auth via `Authorization` header when key non-empty (:1825-1830).
+- Loop-carried vars must be top-level locals in the fn, mutated as if-expressions at while-body
+  top level (see :2760-2791 pattern + comment :2903-2904 region).
+- Error shape: `str_starts_with(raw,"{\"error\"") || str_contains(raw,"\"error\":")` → return
+  `{"error":"llm unavailable","reply":""}` (:1835-1838).
+
+## Remaining read map (before writing the fork)
+- chat.el 2840-3200: block walk (2923-3000), policy gate (3009-3023: classify_tool_risk /
+  is_builtin_tool / ask_all / tool_auto_approved → needs_bridge), dispatch_tool call (3025),
+  tool_result feedback (3031, 3067-3072), run-progress ledger append (3078-3087), bridge_save
+  (3182), loop end + done envelope (~3100-3200).
+- agentic_resume 3227-3293 (hardcoded Anthropic headers to make wire-aware; blob gets `wire` field,
+  legacy default anthropic) · handle_tool_result 3293+ · dharma fork site 3465 (calls agentic_loop
+  direct, no use_openai check today).
+
+## Write plan (order)
+1. Env fallbacks (edit llm_base_url/llm_wire_format/agentic_api_key) — small, first, testable alone.
+2. `openai_tools_json(anthropic_tools: String) -> String` converter (walk array; per entry build
+   {"type":"function","function":{name,description,parameters:input_schema-raw}}).
+3. `openai_agentic_loop(...)` fork: same signature as agentic_loop minus Anthropic-only params;
+   INCLUDE run-progress ledger + tools_log + iteration cap 12; NO container_id/ws_drift/web_search
+   (out of scope; strip web_search entry from tools via agentic_tools_literal()+connector merge,
+   NOT _with_web()).
+4. Fork sites ×3: handle_chat_agentic :2695-2700 (route agentic to new loop when use_openai);
+   dharma :3465; agentic_resume wire-branch.
+5. `chat.elh` extern decls. 6. Compile (recipe: dist/ + elc/elb per neuron-soul-build-deploy memory;
+   round-9 tree soul.c regen'd 08-06 proves toolchain live). 7. Gate: stub selftest recipe in
+   tests/gate-openai/README.md. 8. Anthropic-lane regression via gate9 (READ-ONLY consume from
+   _wt-beta-round9). 9. Live Groq E2E (scratch profile, free port, key via Keychain read-only).

+`~/el-sdk/el_runtime.c` (Jun 15) is MISSING builtins the Aug engine calls (`engram_wm_count`,
+`engram_wm_top_json`, `http_delete_json`, `http_serve_async`) → link fails with
+"symbol(s) not found for architecture arm64". Use the REPO-PINNED runtime:
+```
+mkdir -p <scratch>
+elb --elc=$HOME/el-sdk/elc --runtime=vendor/el-runtime/v1.0.0-20260501 --out=<scratch>/

+Source: `_engine-plainchat-20260805/README.md:396-412`. Verified today: 0 errors, 887,296 B.
+`elb` ALSO rewrites every `*.elh` in the tree (cosmetic em-dash→hyphen in the auto-gen banner,

+stray before staging, or the diff drowns in noise.
+
+## SELF-REVIEW FIX LIST (found by reading my own diff, 2026-08-06 — apply in ONE batch, then rebuild once)
+- **F3 (CORRECTNESS, do first):** the assistant echo currently replays the provider's FULL
+  `tool_calls` array (`tc_arr`) while the loop answers only the FIRST call. If a provider ignores
+  `parallel_tool_calls:false`, the next request carries an assistant turn with N tool_calls and
+  only ONE `role:"tool"` response → most OpenAI-format providers 400 ("missing tool response for
+  id X") and the run dies. This is the same class as ADR-0005's Anthropic failure, but here it is
+  cheap to close: echo ONLY the honored call (`"[" + tc0 + "]"`), so the conversation we send is
+  self-consistent and the dropped call never existed from the model's view. The DRIFT log line
+  stays (honest accounting of what we dropped).
+- **F4 (efficiency/latency):** `handle_chat_agentic` computes `agentic_tools_all()` at ~:2681
+  BEFORE the fork, then the OpenAI branch computes `agentic_tools_no_web()` again — two
+  `connector_tools_json()` calls per turn, each an HTTP round-trip to the connector bridge on
+  :7771 (two timeout exposures). Fix: compute the tools array ONCE, per lane, after `use_openai`
+  is known (check no other use of `tools_json` sits between :2681 and the fork before moving it).
+  Note: `openai_tools_json()` already skips any entry with no `input_schema`, so Anthropic's
+  server-side `web_search` entry is auto-dropped even if the full array is passed —
+  `agentic_tools_no_web()` is kept for EXPLICITNESS, not necessity.
+- **F1 (debuggability):** the "no choices in response" branch logs a generic string and discards
+  the body. Log the response head (as the `is_error` branch does) — a provider that returns 200
+  with an unexpected shape is otherwise undiagnosable from the log.
+- **OPEN QUESTION (evidence pending from the gate):** the tool-result feedback turn escapes with
+  `json_escape()` (this lane's escaper) rather than `json_safe()` (used everywhere else). The
+  Anthropic lane escapes that field with NEITHER, which is a latent defect on that side. If the
+  torture scenario shows any escaping loss, switch to `json_safe` and note the Anthropic-side
+  finding for Will.
+
+## TEST HARNESS — built 2026-08-06 (Task 4 side-work, reusable by anyone)
+- `tests/run-el-test.sh <tests/test_x.el> | --all` — the engine tests were NEVER runnable
+  before this (`elc` is a compiler: emits C to stdout and exits). It emits the test to C,
+  compiles `soul.c` separately with `main` renamed away (soul.c owns the daemon's real main
+  but also defines `layered_cycle` et al.), links the remaining modules + the repo-pinned
+  runtime, and executes. Modules cached under `/tmp/el-test-<worktree>/`; `REBUILD=1` forces.
+- **The runner computes the verdict itself** because the test FILES cannot: all 9 counted
+  test files do `let pass_count = pass_count + 1` inside an if BLOCK, which El scoping
+  discards, so every summary line reads `0 passed, 0 failed` forever. Per-assertion
+  `PASS:`/`FAIL:` lines ARE reliable; the runner counts those, exits non-zero on any FAIL
+  or on zero assertions, and was proven to discriminate with a negative control (broken
+  assertion → 31 passed / 1 failed / exit 1). Real in-file fix filed: **neuron#116**.
+- `tests/test_bridge_serialization.el`: 4 `bridge_save` calls updated for the new `wire`
+  argument, plus **Section 9** (8 new assertions) covering wire round-trip both ways, the
+  legacy no-wire blob (resumes as anthropic), and a FIELD-ORDER decoy guard — a fake
+  `"wire":"anthropic"` planted inside `messages_raw` must not beat the blob's own scalar.
+  That decoy is the round-9 first-match-scanner bug class, now pinned by a test. **32/32 green.**
+
+## MEMORY-SAVE CAVEAT RESOLVED 2026-08-06
+Earlier saves this session reported `-> OUTBOX only (real mind unreachable or read-back
+failed)`. That was a **read-back verifier false negative, not data loss** — a direct
+`POST :7770/api/neuron/recall` returns those notes from the live mind verbatim. Another
+terminal was fixing exactly this (multi-word read-back probe) the same afternoon. Do NOT
+re-save on an OUTBOX report without first querying the mind directly, or you duplicate nodes.
+
+## Standing cautions
+- PERSIST OFF on the real mind this boot (neuron#98/#92): journal saves only, ferry later. MCP link
+  down this terminal; use neuron_remember.py / neuron_recall.py.
+- Aug-16: Groq retires llama-3.3-70b-versatile (separate P0, Tim's call, catalog swap).
+- Never bind 7770/7779/17779; never touch ~/.neuron; round-9 worktrees read-only.

+  `return e`, `if c { a } else { b }` as an expression, `+` concatenation,
+  `"..."` with backslash escapes, `//` line comments. No block comments, no
+  const/match/struct exist in this dialect (verified over the whole tree).
+
+KEY PATTERNS — the only two things a key expression can resolve to
+  EXACT  "soul_model"          the whole key is known
+  PREFIX "session_hist_"       a known head, then runtime text
+  (plus UNRESOLVED, which is a report line and never a failure)
+
+RESOLUTION — resolve_expr() returns a SET of patterns; unions are how branches,
+multiple returns, and multiple bindings of one name are represented.
+  literal        "k"                    -> {EXACT k}
+  concat         A + B                  -> fold left; all-static -> EXACT,
+                                          static head + dynamic tail -> PREFIX
+  if-expression  if c {A} else {B}      -> resolve(A) | resolve(B), except that
+                                          str_eq(X,"") with X statically ""
+                                          folds to the taken branch only
+  call           f(args)                -> union over f's return expressions,
+                                          with f's params bound to THIS call
+                                          site's actual argument expressions
+  local var      let k = e; state_get(k)-> union over every `let k =` in the
+                                          enclosing function
+  parameter      fn g(k) { state_get(k) }-> union over the argument at that
+                                          position across every call site of g
+  anything else  json_get(...), env(...)-> UNRESOLVED
+Recursion is depth- and cycle-guarded; a guard trip yields UNRESOLVED, never a
+failure.
+
+COVERAGE — a read is satisfied when some write can produce the same key:
+  read EXACT k   <- write EXACT k, or write PREFIX p where k starts with p
+  read PREFIX p  <- write EXACT k where k starts with p, or write PREFIX q
+                    where p and q are prefixes of each other
+Deliberately permissive at the boundaries: a gate that cries wolf gets deleted.

+#
+# ── WHY THIS EXISTS. DO NOT DELETE IT AS NOISE. ──────────────────────────────
+#
+# The engine keeps runtime values in a key-value store: state_set("k", v) writes,
+# state_get("k") reads. A read of a key that NOTHING writes returns an empty
+# string. Silently. No error, no warning, no log line. The El compiler cannot see
+# it, no test sees it, and the product keeps running — just with a hole in it.
+#
+# That is how issue #129 happened. ff421d3 (2026-08-05) correctly moved
+# conversation history to a per-session key behind conv_hist_key(session_id). One
+# consumer did not move with it: the agentic path's L1 safety screen kept reading
+# the old anonymous "conv_history" bucket. The desktop app always mints a session
+# id, so history was always written under session_hist_<id> and that read always
+# returned "". The half of the crisis score that receives history is the
+# ESCALATION half — the one that exists for distress building across several
+# turns, where no single message trips the bell on its own. It scored 0 on every
+# real conversation for two days, and nothing failed.
+#
+# The line that broke carried a comment describing this exact bug being fixed
+# once already, under issue #9. A comment is not a gate. This is the gate.
+#
+# ── WHAT IT CHECKS ──────────────────────────────────────────────────────────
+#
+#   DEAD-READ    a state_get whose key resolves to something no state_set in the
+#                tree produces. The direct form of the class.
+#
+#   HAND-ROLLED  a state_get/state_set that spells out a literal belonging to a
+#                key namespace a helper function owns (e.g. "conv_history", owned
+#                by conv_hist_key()). This is #129's actual shape: the producer
+#                moved behind the helper and one consumer kept the old spelling
+#                by hand. DEAD-READ alone does NOT catch #129, because the dead
+#                handle_chat() still writes that key through the helper — so this
+#                second check is the one that earns the gate its keep.
+#
+# ── WHY IT DOES NOT CRY WOLF ────────────────────────────────────────────────
+#
+# Keys are usually COMPUTED, not literal, so a naive grep would flood and get
+# switched off within a day. scripts/state-key-audit.py resolves computed keys:
+# string concatenation (matched on the static prefix), helper functions (resolved
+# to their possible return values), keys built into a local variable, and keys
+# arriving as a function parameter (resolved through the call sites). Where a key
+# genuinely cannot be resolved it is printed under UNRESOLVED and does NOT fail
+# the build — visible, never silently ignored. Keep that list short.
+#
+# On this tree it resolves 278 of 278 sites: UNRESOLVED is 0 and FINDINGS is 0.
+#
+# Two declaration files, both of which should only ever shrink:
+#   scripts/state-key-external.txt  keys a host outside the El tree writes
+#   scripts/state-key-baseline.txt  findings that predate the gate (real debt)
+#
+# ── PROVEN TO DISCRIMINATE (2026-08-07) ─────────────────────────────────────
+#
+#   1. Synthetic: a scratch copy of this tree with agentic_safety_screen reverted
+#      to the pre-fix state_get("conv_history") — ONE line, nothing else — FAILS
+#      with `chat.el:2536 ... conv_hist_key() owns this key namespace`. The tree
+#      as shipped PASSES. One variable, opposite verdicts.
+#   2. Independent: run read-only against origin/feat/soul-openai-tools-v2, which
+#      carries the same defect on its own, the gate reported chat.el:2937 — the
+#      exact line 43d0449's commit message had named by hand. Against that
+#      branch's fix (origin/fix/129-on-openai-tools) it passes.
+#   3. Producer-moved controls: renaming the sole writer of an EXACT key
+#      (soul_model) orphans 3 readers across 3 files; renaming the sole writer of
+#      a PREFIX namespace (agent_workspace_root_*) orphans 3 readers — including
+#      when the producer moves to a NARROWER namespace, which an earlier,
+#      sloppier prefix rule let through.
+#
+# It also found, on its first run, a defect nobody was looking for: soul.el's
+# `state_set("soul_identity", ...)` was deleted on 2026-05-13 in b163fa6 (a
+# commit about awareness/ISE writes) and five readers in chat.el were left

+# gate-openai — deterministic OpenAI-dialect provider stub
+
+Staging home for the **soul-openai-tools-v2** gate scaffolding
+(`docs/specs/SPEC-soul-openai-tools-v2-2026-08-06.md`, test-plan rung 1:
+"stub first — discriminates before El code exists"). Sibling of gate9's
+Anthropic stub (`_wt-beta-round9/scripts/gate9/stub-llm.py`): same scenario
+mechanism, opposite wire dialect. Stdlib Python only, 127.0.0.1 only,
+refuses ports 7770/7779/17779. Run `./selftest.sh` — exit 0 is green.
+
+## Files
+
+| File | Role |
+|---|---|
+| `stub-openai.py` | HTTP server: `POST /v1/chat/completions` (OpenAI dialect), scenario-scripted responses, request validation, ground-truth JSONL log, hostile modes via `--mode` |
+| `scenarios-openai.json` | Scenario contract: scripts + markers + per-class/per-step request assertions |
+| `selftest.sh` | curl-driven proof of every scenario, every rejection, all hostile modes (58 checks) |
+
+## What each scenario proves (when the brain drives it)
+
+| Class | Proves |
+|---|---|
+| `oa-plain` | finish_reason `stop` ends the loop; tools + `tool_choice` + `parallel_tool_calls:false` were offered on the wire |
+| `oa-tools-off` | the chat-only lane sends NO tools (offering them there is a 400) |
+| `oa-single-tool` | full round-trip: `tool_calls` parsed, assistant echo + `role:"tool"` turn with matching `tool_call_id` sent back, final text reached |
+| `oa-torture` | `function.arguments` (JSON-encoded string with nested quotes, backslashes, newlines, tabs, unicode) survives exactly ONE decode — the stub recomputes the issued payload from the script and 400s on any drift (`gate_echo_mismatch`, the spec §6 two-escaper trap) |
+| `oa-parallel` | two `tool_calls` in one response: the brain either answers both (paired correctly) or rejects cleanly — an unpaired echo is a 400 |
+| `oa-mission` | multi-round loop continuation; step index = assistant-message count, so resume threads index correctly by construction |
+| `oa-api-error` | provider errors 400/429/500/503 in the OpenAI error envelope surface honestly, no retry storm |
+
+Universal (every request, any scenario): Anthropic dialect leakage fails
+loudly with 400 — `anthropic-version` header, top-level `system` /
+`stop_sequences` / `max_tokens_to_sample`, `input_schema` inside tools,
+Anthropic content blocks (`tool_use`/`tool_result`/...). Tools must be
+`{type:"function", function:{name, description, parameters}}`, unique names;
+echoed `arguments` must be a JSON-encoded STRING, never a decoded object.
+
+## Hostile modes (`--mode`, same file)
+
+| Mode | Behavior | Brain invariant under test |
+|---|---|---|
+| `black-hole` | reads the request, never responds | HTTP timeout exists and surfaces; no silent hang |
+| `mid-body-drop` | 200 headers, half a JSON body, socket abort | truncated body = clean error, never a half-parsed reply shown as real |
+| `tool-pending-forever` | every request gets a fresh `tool_calls` response, forever | the loop's iteration cap trips (`max_loop_iterations: 16` in the contract); count actual round-trips via `GET /gate/stats` (`chat_hits`) |
+
+## How the brain-side gate consumes this
+
+1. Start: `stub-openai.py --port P --scenarios scenarios-openai.json --log run.jsonl`
+2. Point the brain at it: `NEURON_LLM_0_URL=http://127.0.0.1:P` +
+   `NEURON_LLM_0_FORMAT=openai` (spec step 0 must verify these actually
+   export at runtime), scratch profile, free soul port.
+3. Send each phrasing's `prompt` (the marker selects the script); assert the
+   brain's claims (`tools_used`, reply, ledger) against the stub's JSONL log
+   — truth, not narration — plus files on disk for write_file scenarios.
+4. Any stub 400 = the brain sent a malformed/leaked request; the gate fails
+   with the stub's reason string.
+5. Re-run gate9's Anthropic matrix unchanged = proof the Anthropic lane is
+   byte-untouched.
+
+## Reconciliation into gate9 (app repo) — AFTER round 9 merges
+
+This dir is staging only; the merge is mechanical by design:
+- `stub-openai.py` + `scenarios-openai.json` move to `scripts/gate9/`
+  alongside `stub-llm.py` + `scenarios.json` (shared conventions: marker
+  matching, assistant-count step indexing, `--port/--scenarios/--log`,
+  JSONL fields `seq/ts/kind/scenario_class/phrasing/step/validation/
+  delivered/http_status`, prod-port refusal, benign background responses,
+  `GATE-SCRIPT-EXHAUSTED` overrun, `{N}/{NN}` repeat expansion).
+- `prompt-matrix-gate.sh` gains a dialect axis (anthropic|openai) choosing
+  stub + scenario file; `matrix-asserts.py` reads the same log shape.
+- The `--mode` hostile flags here are PROVIDER-side (brain↔LLM boundary);
+  gate9's `hostile/` servers are SOUL-side (app↔brain boundary). They are
+  complementary, not duplicates — both stay.
+
+## Open questions for the port author (stub asserts a position; confirm or change)
+
+1. `parallel_tool_calls` must be **explicitly false** on every tool-bearing
+   request (ADR-0005 pin). If the builder omits it instead, relax
+   `defaults.expect_request.parallel_tool_calls` to `null`.
+2. `tool_choice` must be present (`"auto"` expected). If the brain relies on
+   the provider default, drop `require_tool_choice`.
+3. Tool-result `content` is asserted only to be a string; if the brain sends
+   structured JSON-in-string (like `{"ok":true,...}`), no change needed.
+4. Groq compatibility: Groq's OpenAI-compat endpoint rejects some optional
+   fields; whatever field set the brain settles on for live Groq E2E must be
+   mirrored here so the deterministic gate and the live lane assert the SAME
+   request shape.
+5. The stub treats a `role:"tool"` turn answering an already-answered id as
+   400; if the resume path can legitimately replay tool results, that rule
+   needs a resume-aware carve-out (gate9's Anthropic stub faced the same
+   issue — see its PASS 1 comment).

+# run-lane-gate.sh — brain-side driver for the OpenAI-dialect gate.
+#
+# Drives the REAL soul binary against stub-openai.py for every class and every
+# phrasing in scenarios-openai.json, plus the three hostile provider modes, and
+# asserts the brain's claims against the stub's ground-truth JSONL (truth, not
+# narration) and against files on disk.
+#
+# SAFETY (hard rules, enforced below):
+#   - never binds 7770 / 7779 / 17779   - only 7891-7894
+#   - never reads or writes ~/.neuron   - HOME is redirected to a scratch dir
+#   - every process started here is killed on exit (trap) and proven with lsof
+#
+# The soul runs under `script -q /dev/null` so its stdout is a pty: El's
+# println() uses puts(), which is FULLY buffered to a file, and the process is
+# killed without flushing — the DRIFT lines would be invisible otherwise.
+#
+# Usage:  ./run-lane-gate.sh [all|bridge|local|toolsoff|hostile]
+#   bridge   = consent round-trip config (no workspace root -> write_file is
+#              "escalate" -> the loop suspends and the CLIENT executes the tool)
+#   local    = workspace-root config (write_file is "reversible" + builtin ->
+#              the loop executes the tool in-process and runs to completion)
+#   toolsoff = supplementary: non-agentic lane against a base URL WITHOUT the
+#              /v1 suffix (the el-runtime provider chain appends
+#              /v1/chat/completions itself, unlike chat.el which appends only
+#              /chat/completions)

+"""stub-openai.py - deterministic local stand-in for an OpenAI-format
+/v1/chat/completions provider, for the soul-openai-tools-v2 gate
+(docs/specs/SPEC-soul-openai-tools-v2-2026-08-06.md). No API key, no network,
+no model.
+
+Sibling of gate9's stub-llm.py (Anthropic dialect, _wt-beta-round9/scripts/
+gate9/): same scenario mechanism (marker matching, assistant-count step
+indexing, ground-truth JSONL log, prod-port refusal), different wire.
+Staging home is tests/gate-openai/ in _wt-openai-tools; folds into
+scripts/gate9/ after round 9 merges (see README.md).
+
+WHAT IT DOES
+  * Serves POST /v1/chat/completions on 127.0.0.1 only (OpenAI dialect).
+  * VALIDATES every request - this is the gate's discriminator, built
+    BEFORE the brain-side El code exists so dialect leakage fails loudly:
+      - Anthropic tells are 400 code=gate_dialect_leak: `anthropic-version`
+        header; top-level `system` / `stop_sequences` / `max_tokens_to_sample`
+        / `anthropic_version`; `input_schema` inside a tool entry; Anthropic
+        content blocks (tool_use / tool_result / server_tool_use / ...).
+      - tools[] must be OpenAI-shaped {type:"function", function:{name,
+        description, parameters}} with unique names -> 400 gate_tools_shape.
+      - assistant tool_calls echoes must be {id, type:"function",
+        function:{name, arguments:<JSON-encoded STRING>}}; a decoded-object
+        `arguments` is a wire bug -> 400 gate_tool_call_shape.
+      - every assistant tool_calls turn must be answered by role:"tool"
+        messages covering EVERY tool_call_id, immediately following;
+        unknown / duplicate / missing ids -> 400 gate_pairing.
+      - echoed `arguments` for gate-issued call ids (call_gate_*) are
+        recomputed from the script and compared after ONE json decode ->
+        400 gate_echo_mismatch. This is the two-escaper-trap discriminator
+        named in the spec's security model (section 6).
+      - scenario-level request expectations from scenarios-openai.json
+        (tools offered, OpenAI-shaped tool_choice, parallel_tool_calls
+        pinned false per ADR-0005) -> 400 gate_expect.
+  * Answers with SCRIPTED responses: plain text (finish_reason "stop"),
+    tool calls (finish_reason "tool_calls", arguments JSON-encoded, incl. a
+    nested-quote/escaping torture payload and a parallel two-call case), and
+    API-error injection (OpenAI error envelope). Scenario is selected by
+    scanning user-message text (newest first) for a registered marker
+    substring; the step index is the number of assistant messages already in
+    the request (stateless replay - resumes index correctly by construction).
+  * Writes a ground-truth JSONL log (--log): one record per request with the
+    validation verdict, matched scenario/step, and exactly which tool calls
+    were delivered. Gate assertions compare the brain's claims against THIS
+    log - truth, not narration.
+  * Unmatched requests (boot probes, awareness chatter) get a benign "ok"
+    text response, logged kind=background, never counted as ground truth.
+  * HOSTILE MODES (--mode) on the same file:
+      black-hole            accept + read the request, never respond;
+      mid-body-drop         send half a JSON body, then abort the socket;
+      tool-pending-forever  every request gets a FRESH tool_call
+                            (finish_reason "tool_calls"), forever - tests
+                            the agentic loop's iteration cap; count the
+                            brain's round-trips via GET /gate/stats.

+# run-el-test.sh — build and RUN one engine test (tests/*.el), printing its assertions.
+#
+# WHY THIS EXISTS (2026-08-06): the engine's tests/*.el files were never runnable from the
+# tree. `elc` is a COMPILER — it emits C to stdout and exits; it does not execute anything.
+# So "the tests" could only ever be read, not run, and a signature change could silently
+# break them (exactly what happened when bridge_save gained its `wire` argument). This
+# script closes that: emit the test to C, link it against the engine modules, execute it.
+#
+# HOW IT WORKS
+#   1. elc <test>.el              -> C on stdout (the test file's `main` + prototypes)
+#   2. elb (once, cached)         -> per-module C for the whole engine into a scratch dir
+#   3. cc test.c + all modules EXCEPT soul.c (soul.c owns the real `main`) + the runtime
+#   4. run it
+#
+# The test C references only the engine functions it actually calls, so there are no
+# duplicate-symbol collisions with the module objects.
+#
+# RUNTIME: the REPO-PINNED vendor/el-runtime (NOT ~/el-sdk/el_runtime.c — that June build
+# is missing builtins August code calls: engram_wm_count, engram_wm_top_json,
+# http_delete_json, http_serve_async; linking against it fails with "symbol(s) not found").
+#
+# USAGE
+#   tests/run-el-test.sh tests/test_bridge_serialization.el     # one test
+#   tests/run-el-test.sh --all                                  # every tests/test_*.el
