+
+**Intelligence Routing — Self-Healing Parser System**
+
+When the Command Code model produces output in unpredictable or unrecognized formats, the multi-format parser chain (DSML, XML, explore_agent, bash blocks, raw JSON, fallback regex) can return empty. This causes the Codex agent loop to stall — zero tool calls means nothing to execute.
+
+Intelligence Routing is a **three-layer self-healing system** that ensures the agent loop always continues:
+
+### Layer 1: Deep URL Extraction (FIX 23)
+- **Problem**: `<explore_agent>` body contained `messages: [{"content": "https://..."}]` — URLs hidden inside JSON values. Regex couldn't match because it excluded the `"` character that terminates JSON strings.
+- **Solution**: `_build_explore_cmd()` extracted to module level (was a closure inside `_parse_commandcode_text_tool_calls`). After initial regex fails, tries `json.loads()`, iterates list items, extracts `content` field to find URLs. Added `"` to regex exclusion set.
+- **Self-tests**: Pattern M, O, O2 verify URL extraction from nested JSON.
+
+### Layer 2: Escalation Block Handling (FIX 24)
+- **Problem**: Model produces `<require_escalation>` and `<request_escalation_permission>` blocks when it wants elevated permissions. CC adapter doesn't support escalation — blocks silently dropped → `parsed_tool_calls=0` → stall.
+- **Solution**: Two handlers:
+  - FIX 24a: Closed-tag blocks — extracts URL if present and runs explore command; otherwise echoes auto-proceed.
+  - FIX 24b: Bare/unclosed tags (`<require_escalation />`) — auto-proceeds with diagnostic echo.
+- **Self-tests**: Pattern N, N2 verify both closed and bare escalation blocks.
+
+### Layer 3: Intent-Based Command Synthesis (FIX 25 — THE CORE)
+- **Problem**: After ALL parsers return empty, the agent loop has zero tool calls. Model may have written plain English ("I need to fetch the README"), partial JSON, or completely unrecognized formats.
+- **Solution**: 5-heuristic synthesis chain in `cc_stream_to_sse()`, run when `parsed_tool_calls=0` and text has content:
+  1. **URL in text** → `curl` to fetch it
+  2. **File path reference** ("read the file /path/to/X") → `cat` or `ls` that file
+  3. **Shell command in backticks/quotes** → extract and run it
+  4. **"explore"/"fetch"/"investigate"/"repository" intent** + last user URL → `_build_explore_cmd()` with `_last_user_urls` deque
+  5. **"I need to"/"let me"/"please" intent text** → echo diagnostic with the intent
+- The system NEVER returns empty tool calls when there's text to analyze.
+- **Self-tests**: Patterns M-O2 cover the full pipeline.
+
+### Architecture
+```
+_parse_commandcode_text_tool_calls()  ←  Layer 1 + Layer 2
+cc_stream_to_sse()                    ←  Layer 3 (after parser chain + fallback)
+_last_user_urls deque (maxlen=20)     ←  Session-wide URL memory for heuristic 4
+```
+
+### Test Coverage
+- **54 self-test patterns** (up from 41 in v3.6.0)
+- 13 new tests covering all three Intelligence Routing layers
+- Tests verify: nested JSON URL extraction, closed/bare escalation blocks, module-level explore command builder

+FIX 21: DSML parser silently drops tool calls when model uses name="cmd" (THE HALT BUG)
+  Symptom: Codex CLI stops mid-task. Model generates valid DSML exec_command with

+        Parser returns parsed_tool_calls=0. Client sees text output but no tool to execute.

+  Root cause: Line 1798 had `if key == "command":` — only matching parameter name="command".
+        The actual tool schema defines the parameter as "cmd" (see exec_command schema).
+        When DeepSeek generates name="cmd", the key "cmd" != "command", so cmd stays None,
+        and line 1825-1826 `if not cmd: continue` silently skips the entire tool call.
+        The XML parser (line 2205) already handled both: `params.get("command") or params.get("cmd")`
+        but the DSML parser did not.
+  Fix: Changed to `if key in ("command", "cmd"):` in the DSML parameter loop.

+INTELLIGENCE ROUTING — Self-Healing Parser System (v3.7.0)
+════════════════════════════════════════════════════════════════════
+
+Problem: The Command Code model produces output in unpredictable formats
+that change between sessions and models. When the multi-format parser chain
+(DSML → <bash> → <explore_agent> → <tool_call type=...> → XML → raw JSON →
+fallback regex) returns empty, the Codex agent loop has zero tool calls and
+STALLS — the user sees the model "thinking" but nothing happens.
+
+Intelligence Routing is a three-layer self-healing system:
+
+LAYER 1 — Deep URL Extraction (FIX 23)
+  The <explore_agent> handler was failing because URLs were hidden inside
+  nested JSON: messages: [{"content": "https://..."}]. The regex couldn't
+  find them because it excluded the " character that terminates JSON values.
+  
+  Solution: _build_explore_cmd() is now a module-level function (was a
+  closure). After the initial regex fails, it tries json.loads() on the
+  text, iterates list items, and extracts the "content" field to find URLs.
+  Also added " to the regex exclusion set and rstrip characters.
+
+LAYER 2 — Escalation Block Handling (FIX 24)
+  The model produces <require_escalation> and <request_escalation_permission>
+  blocks when it wants elevated permissions. The CC adapter doesn't support
+  escalation — these blocks were silently dropped, causing parsed_tool_calls=0.
+  
+  Solution: Two handlers:
+    - FIX 24a: Closed-tag blocks — extracts URL if present, runs explore cmd;
+      otherwise echoes auto-proceed message.
+    - FIX 24b: Bare/unclosed tags (<require_escalation />) — auto-proceeds.
+
+LAYER 3 — Intent-Based Command Synthesis (FIX 25, THE CORE)
+  When ALL parsers return empty and text has content, the system plays
+  detective using 5 heuristics in priority order:
+  
+    1. URL detected in text → curl to fetch it
+    2. File path reference → cat or ls that file
+    3. Shell command in backticks/quotes → extract and run
+    4. "explore"/"fetch"/"investigate" intent + last user URL → explore cmd
+    5. "I need to"/"let me"/"please" intent text → echo diagnostic
+
+  This ensures the agent loop ALWAYS has a tool call to execute, even when
+  the model's output format is completely unrecognized. The loop never stalls.
+
+Architecture:
+  _parse_commandcode_text_tool_calls() — LAYER 1 + LAYER 2
+  cc_stream_to_sse() — LAYER 3 (runs after parser chain + fallback)
+  
+  The _last_user_urls deque (maxlen=20) tracks URLs from user messages
+  across the session, giving Layer 3 heuristic 4 a URL to work with.
+
+  Self-tests: 54 patterns (was 41) covering all three layers.
