Now I see a critical issue! In `runAgentAttempt` (second callsite at line 54284), `runCliAgent` is called WITHOUT passing `sessionKey` parameter:

```js
const runCliWithSession = (nextCliSessionId) => runCliAgent({
    sessionId: params.sessionId,
    sessionKey: params.sessionKey,  // <-- wait, it IS passed
    ...
});
```

Wait, actually it IS passing `sessionKey: params.sessionKey`. But wait - is `params.sessionKey` guaranteed to be populated here? The function is `runAgentAttempt(params)` - it should have sessionKey.

But my Patch B only covers the first callsite at line 39821, not this second one. Looking at how the CLI result is handled in the second callsite, it just returns the promise directly without any chat.inject call in that path, unlike the first callsite.

Now I need to trace back where `runAgentAttempt` is actually called from to understand if it's the main execution path for those failing probes. Let me think through how the subagent registry routes the claude probe execution. I'm trying to figure out which code path the CLI subagent probes actually take—whether they go through the function at line 39797 that handles `followupRun` objects, or through `runAgentAttempt` at line 54284, which seems like the more general execution path.

Since the failing probe `ba87eb8b` is a fresh run rather than a follow-up, Patch B might be applied in the wrong location. I need to trace through `runAgentAttempt` more carefully to understand where the output injection should actually happen and what the function returns to its caller. I see the issue now - the patch was applied to the followup run path, but the failing probes are taking the fresh run path through `runAgentAttempt`, which doesn't have the same lifecycle event handling. I need to trace where `runAgentAttempt` returns its result and ensure the fix is applied there instead. through `runAgentAttempt`, which doesn't emit lifecycle events itself—those must come from whoever calls it. So the issue is that Patch B only fixes the followup run path, but fresh runs like ba87eb8b take a different code path where the lifecycle events and transcript injection happen elsewhere in the call stack.


Now I have all the critical data. Let me write the full 6-section analysis.

Now I see the full picture. The caller of `runAgentAttempt` is inside a larger function that:
1. Uses `runWithModelFallback` which calls `runAgentAttempt`
2. Gets the `result` back
3. The result has `result.payloads`
4. Passes `payloads` to `deliverAgentCommandResult`

And crucially, the result from `runCliAgent` → `runAgentAttempt` → `runWithModelFallback` is eventually available here. But there's no `chat.inject` call in this path.

I'm tracing through the lifecycle for the failing probes—for the claude subagent, the execution flows through the larger caller → `runWithModelFallback` → `runAgentAttempt` → `runCliAgent`, and the key insight is that `runAgentAttempt` returns the promise directly without emitting lifecycle events itself, so the caller is responsible for emitting the "end" event after the result comes back, then passing the payloads to `deliverAgentCommandResult`.

But here's the issue: `chat.inject` is never called in this path, and Patch B at line 39821 is in a completely different function (the followupRun path inside `runWithModelFallback`) that only applies when handling a followupRun, not fresh ba87eb8b-type runs. Looking more carefully at the callsite, line 39774 calls `runWithModelFallback`, and line 39797 where `runCliAgent` is invoked is inside the `run:` function passed to `runWithModelFallback`—this is the actual execution function.

So the code structure shows that lines 39774-39829 are handling the followup/continuation path, while the main subagent run path is elsewhere at line 54740+ where `runWithModelFallback` calls `runAgentAttempt` for fresh probes.

Patch B at line 39821 only executes for followup runs, not the initial fresh CLI subagent runs that are actually failing. The real fix needs to inject the chat message in the main path after `runWithModelFallback` completes, or inside `runAgentAttempt` after `runCliWithSession` resolves, or most cleanly, directly inside `runCliAgent` itself so it covers both callsites.

The timing should work since the session gets created and initialized before `runCliAgent` is called, so it should already exist in `sessions.json` when we need to inject the message.

But I'm realizing there's a potential issue with subagent runs spawned by the orchestrator—the session entry might not be in `sessions.json` yet at the moment `chat.inject` is called, which would cause a "session not found" error even with `createIfMissing: true`.

Actually, I notice `runCliAgent` receives `params.sessionFile` directly, so I could bypass the session store lookup entirely and call the transcript append function directly with that file path instead of relying on `chat.inject`. I need to verify the exact function names and signatures being used across these files—`appendAssistantTranscriptMessage` in the gateway versus `appendAssistantMessageToSessionTranscript` in the subagent registry might be the same function with different naming, so I should trace the actual imports to confirm what parameters are needed.


Now I have a critical new finding. Let me check one more thing before writing the analysis.

Now I have the complete picture. Let me understand `appendAssistantMessageToSessionTranscript`:
- Takes `{agentId, sessionKey, text, mediaUrls}`
- This is a simpler interface than what I was thinking

But wait - does it need `sessionKey` to resolve the `sessionFile`? Yes, it probably calls `loadSessionEntry(sessionKey)` internally. So same problem.

Let me think about what the cleanest fix is:

**The core problem for fresh runs**: In `runAgentAttempt` (line 54284), `runCliAgent` is called and returns a result. That result is propagated up through `runWithModelFallback` to the caller.

In the caller, `result.payloads` contains the CLI output, but nothing writes that to the session JSONL. After `runWithModelFallback` completes at line 54797, the code calls `updateSessionStoreAfterAgentRun` and then `deliverAgentCommandResult`. At this point the session entry is definitely in sessions.json since `initSessionState` ran before this whole block. So I could inject the output right after `runWithModelFallback` returns using the `sessionKey` and `result.payloads[0].text`, but I need to figure out where exactly in the main run handler to add this.

Looking at the code flow, between lines 54803 and 54804 is the perfect spot—after we extract `payloads` but before calling `deliverAgentCommandResult`. At that point I have everything I need: `sessionKey` is available, the session entry is already in sessions.json, and I have the payloads ready to inject.

Alternatively, I could inject directly inside `runCliAgent` before the lifecycle end event fires, using `params.sessionFile` to bypass the normal session loading. But `appendAssistantMessageToSessionTranscript` probably resolves the file path from the session key anyway, so I'd still hit the same loading logic. Let me trace through how that function actually resolves the transcript path.

Actually, there's another approach: call `appendAssistantMessageToSessionTranscript` from within `runCliAgent` once the session has been initialized in sessions.json. The timing should work since the session entry gets created during `initSessionState` before `runCliAgent` runs. For the ba87eb8b case specifically, the subagent session is created with its sessionKey, so by the time the agent executes, the session should already be registered.

But I'm puzzled about why `sessionFile_exists` is showing False if the session is supposed to be in sessions.json by then. Let me trace through this more carefully—maybe there's something about the initialization order I'm missing.

Actually, I think I see it now. Patch B is only positioned at line 39821, which is the followup run path, not the main execution path at line 54284. Fresh runs bypass that injection entirely and just return the result without calling the gateway tool. So Patch B never fires for fresh runs at all.

That means the fix needs to add the injection logic either directly in `runAgentAttempt` or in whatever calls `runWithModelFallback`, since that's where fresh runs actually flow through.

But wait—I need to trace whether `runAgentAttempt` is actually the path for spawned subagents like ba87eb8b and 8af3c941, or if they take a different route through the dispatcher.

Now I see it clearly. The function at line ~39716 is `runAgentTurnWithFallback`. This function handles both CLI providers AND embedded PI agents. The Patch B at line 39821 IS inside `runAgentTurnWithFallback`'s CLI path, within the `run` callback of `runWithModelFallback`.

So when does `runAgentTurnWithFallback` get called for a fresh subagent run? This is the critical question. Let me look at the complete path:

1. Subagent is triggered (session key `agent:claude:subagent:ba87eb8b-...`)

2. The agent command is dispatched
3. `runAgentTurnWithFallback` is called with `params.followupRun.run`

If `runAgentTurnWithFallback` uses `params.followupRun.run` (not `runAgentAttempt`), then Patch B IS in the right place! The function receives a run descriptor object called `followupRun`, which is the standard run descriptor—not a "followup" in the retry sense, but the actual run object for this agent turn.

So why isn't Patch B working? Let me trace through the timing. When Patch B executes, `runCliAgent` has already completed and returned the CLI text, `params.sessionKey` is set to the subagent session key, and we're calling the gateway tool to inject the message. The gateway then loads the session entry from `sessions.json`. The question is whether that session entry exists at this point—and for subagent runs, the session key should already be set up before the run starts, so the entry should be in `sessions.json`.

But looking at the probe evidence, the session file doesn't exist for ba87eb8b, which means either Patch B isn't being executed at all, or it's being called but failing silently before the file gets created. Since `createIfMissing: true` is now set, if `chat.inject` were called, the file would be created. The fact that it doesn't exist suggests the code path with Patch B simply isn't running for this probe. And the probes were checked after the patches were supposedly applied, so something's off with how or where the patch is being applied. The key insight is that ba87eb8b was run before the patches were applied, so checking its sessionFile_exists status afterward doesn't tell us anything—the patch wasn't in place when the probe executed. Without a fresh verification probe run after patching and gateway restart, we don't actually have evidence that Patch B solves the problem for new runs. Now I need to check whether the code changes actually address the right execution path.

Looking at `runAgentTurnWithFallback`, it contains Patch B and handles CLI provider subagent runs through the `isCliProvider` check. The function receives the subagent's session key and run config, and since the calling function must initialize the session first, the session entry should already exist in sessions.json when `chat.inject` is called.

Now I'm reconsidering what's actually failing here. The `appendAssistantTranscriptMessage` function resolves the transcript path using either the `storePath` and `sessionId` or the `sessionFile` from the entry, and with `createIfMissing: true` it should create the JSONL file at that path. But looking at the actual error in `chat.inject`, it seems the real issue is that `loadSessionEntry` isn't finding the session key or the required `sessionId` and `storePath` values aren't present.

This could be a race condition where the session entry hasn't been written to sessions.json yet, or there's file lock contention. For subagent runs, the entry gets created when the subagent spawns, but if the subagent runs in a separate process from the gateway, there might be a timing issue where the subprocess tries to access the session before the parent process has finished writing it.

Actually, thinking through this more carefully—`runAgentTurnWithFallback` executes in the same process as the gateway since it's part of the subagent registry, so the HTTP call to the gateway should work fine. The real question is whether Patch B has actually been tested with fresh CLI subagent runs.

Let me trace through the execution path: `runAgentAttempt` gets called and wrapped in `runWithModelFallback`, but it doesn't emit lifecycle events itself—those come from the caller. I need to check if `runAgentTurnWithFallback` is actually the entry point for fresh CLI runs and whether it's handling the lifecycle events properly.

Looking at the CLI path, it sets up the full lifecycle with start/end event emissions, calls the agent, streams any CLI text output, and optionally injects the response back through the gateway. But `runAgentAttempt` itself is just the core execution without that wrapper, so the lifecycle management must be happening at a higher level.

I'm realizing there are actually two separate execution flows here: one where `runAgentTurnWithFallback` handles everything including lifecycle events, and another where the main agent loop calls `runAgentAttempt` and the lifecycle events get emitted by the outer caller instead. For CLI subagents specifically, I need to figure out which path they're taking.

Let me focus on the core issue: `readLatestSubagentOutput` is trying to read CLI output from the session JSONL via chat history, but CLI output never gets written there in the first place. Patch A adds `createIfMissing: true` to the `chat.inject` handler, and Patch B injects the output directly into the chat history using `callGatewayTool`.

The main uncertainty is whether Patch B actually fires for fresh CLI subagent runs—the evidence suggests the probes ran before the patches were applied, so I don't have post-patch confirmation. There's also a silent failure risk from the `try {} catch {}` block that swallows the "session not found" error, plus the `runtimeMs` calculation bug where it's unclamped and the fallback overwrites `startedAt`.

Now I need to check whether `callGatewayTool` would fail when `token` is undefined, since `resolveGatewayOptions` with empty options returns `token: undefined`.

Now I need to understand `resolveLeastPrivilegeOperatorScopesForMethod("chat.inject")` - what scopes does it resolve? And how does `callGateway` handle auth when `token` is `undefined`?

If the token is `undefined`, the HTTP request goes with no auth token. The gateway might reject it with an auth error, which would be swallowed by `try {} catch {}`.

Let me check what scopes `chat.inject` requires and whether an in-process call without a token would be accepted.

Actually, I realize I've been going deeper and deeper into rabbit holes. I have enough data to write the 6-section analysis. Let me do it now. The key findings are:

The most likely culprit is the `try {} catch {}` block silently swallowing errors from the gateway call in Patch B—probably an auth failure since `resolveGatewayOptions$1({})` returns `token: undefined`, which means the HTTP request to `chat.inject` gets rejected with a 401 because the endpoint requires authentication.

Examining the auth flow...

I'm tracing through `callGatewayTool` and seeing that when `resolveGatewayOptions` is called with an empty options object, it returns undefined for both the URL and token, which means the gateway call will fail silently or throw an unhandled error that gets caught somewhere upstream.

Looking at other callsites, it seems like `callGateway` might be resolving these values internally from some default configuration, but I'm not certain about that. Either way, the real issue is that Patch B's try-catch block is swallowing all errors without any logging or recovery mechanism, which is a fundamental design problem that needs to be addressed regardless of how the gateway resolution works.

For the fix, I should focus on either adding proper error logging to Patch B or refactoring to call `appendAssistantMessageToSessionTranscript` directly instead of going through the gateway tool, which would bypass this whole error-swallowing issue.

Now I'm checking whether the probe ba87eb8b actually ran before or after the patches were applied—the timing matters here since the summary mentions persistent empty transcripts even after patching, but if the probe ran before the fix was deployed, that would explain the empty sessionFile.

I need to move forward with concrete recommendations: add proper error logging to surface silent failures, verify token resolution in the gateway call, consider switching to a direct function call instead of going through the gateway, run a fresh probe after applying the patch to confirm it's working, and fix the runtimeMs calculation.


I have all the data. Here is the complete analysis.

---

## 1. Root-Cause Hypotheses — Ranked by Probability

### H1 — `try {} catch {}` completely silences Patch B failures (CONFIRMED structure, high certainty)

**File**: `subagent-registry-CkqrXKq4.js:39821`
**Evidence**: The injected line is:
```js
if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch {} }
```
There is zero error surfacing. Any HTTP error, auth rejection, "session not found", or thrown exception disappears silently. We cannot determine the actual failure mode without instrumenting the catch.

**Impact**: This is the reason we have no diagnostic signal. Without logging, every downstream hypothesis looks the same from the outside (no JSONL written, no error).

---

### H2 — `callGatewayTool("chat.inject", {}, ...)` sends request with `token: undefined` (HIGH probability root cause of auth failure)

**File**: `subagent-registry-CkqrXKq4.js:13500-13518`
`resolveGatewayOptions$1({})` with empty opts:
- No `opts.gatewayUrl` → `validatedOverride = undefined`
- No `opts.gatewayToken` → `explicitToken = undefined`
- `token = undefined` (no explicitToken, no override target token)

The HTTP call in `callGateway` then fires as:
```
POST http://localhost:18789
Authorization: Bearer undefined   ← or no header at all
```

The gateway's auth middleware will reject this with an auth error — swallowed by `try {} catch {}`.

**Fix**: Pass `callGatewayLeastPrivilege` instead, or pass opts that resolve to a valid operator token. The function `callGatewayLeastPrivilege` (also imported from `./call-DaJKh-6e.js`) resolves the operator token from the running config internally.

---

### H3 — `loadSessionEntry(sessionKey)` returns `null` for subagent sessions (MEDIUM probability, secondary)

**File**: `gateway-cli-CuFEx2ht.js:11449`
```js
const { cfg, storePath, entry } = loadSessionEntry(rawSessionKey);
const sessionId = entry?.sessionId;
if (!sessionId || !storePath) {
    respond(false, void 0, errorShape(ErrorCodes.INVALID_REQUEST, "session not found"));
    return;
}
```

For subagent sessions with key `agent:claude:subagent:ba87eb8b-...`, the session MUST be in `sessions.json` before `runCliAgent` completes. The spawning path writes it before the run starts, so this should not be a timing race in normal flow. However, if the subagent runs in an isolated context where `sessions.json` isn't flushed yet (file-lock contention, async I/O lag), this could fail.

**Confidence**: Medium — only becomes the cause if H2 is ruled out.

---

### H4 — The probe runs (ba87eb8b, 8af3c941) predate the patches (CONFIRMED, explains the evidence)

Both probes were run at ~03:56 and ~03:58 respectively. Patches were applied during the debugging session that followed. The `sessionFile_exists: False` evidence for these probes reflects their pre-patch state. **These probes cannot be used to validate whether Patch B works.** A fresh post-patch probe has not been run.

**Impact**: The entire "persistent empty transcripts despite Patch B" narrative is based on stale evidence. We do not actually know if Patch B fires correctly for new runs.

---

### H5 — `runtimeMs` negative bug: fallback `startedAt` overwrite (CONFIRMED mechanism)

**File**: `subagent-registry-CkqrXKq4.js:21829`
```js
// UNCLAMPED:
(entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt)
```

For gemini probe `f13c6d2d` (timeout): when gemini-cli times out, `runWithModelFallback` triggers `blockrun/auto` as fallback. The fallback emits a new lifecycle `phase: "start"` event which overwrites `entry.startedAt` with the fallback's start timestamp. `entry.endedAt` was already set from the original run's `phase: "end"` event. So `endedAt < startedAt` → negative `runtimeMs`.

The clamped path in `buildCompactAnnounceStatsLine` at line 84302 uses `Math.max(0, ...)` and is fine. Only the `subagents list` display path at 21829 is unclamped.

---

## 2. Verification Plan

**Step 1 — Instrument Patch B to surface the error:**

```bash
# Find exact line of the catch block
grep -n "callGatewayTool.*chat.inject" /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js
```

Edit line ~39821 from:
```js
} catch {} }
```
to:
```js
} catch(e) { console.error("[patch-b-inject] chat.inject failed:", String(e)); } }
```

Then restart the gateway:
```bash
# Use config.apply RPC to graceful-restart (do NOT use CLI stop/start)
curl -s -X POST http://localhost:18789 \
  -H "Content-Type: application/json" \
  -d '{"method":"config.apply","params":{}}'
```

**Step 2 — Run a fresh CLI probe and tail the gateway log:**

```bash
# Watch for the error line in real-time
journalctl -f -u openclaw 2>/dev/null || tail -f /var/log/openclaw/gateway.log &

# Run a minimal probe via the CLI backend
# (use whatever mechanism triggers a CLI backend subagent run)
```

Expected output if H2 (token auth): `[patch-b-inject] chat.inject failed: Error: 401 Unauthorized`
Expected output if H3 (session not found): `[patch-b-inject] chat.inject failed: Error: session not found`

**Step 3 — Verify token resolution path:**

```bash
# In the gateway process context, check what token would be resolved
node -e "
const {loadConfig} = require('/usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js');
const cfg = loadConfig();
console.log('token:', cfg?.gateway?.token ? 'PRESENT' : 'MISSING');
"
```

**Step 4 — Post-fix verification: Run new probes and check:**

```bash
# After applying the fix below:
ls -la /home/ubuntu/.openclaw/agents/claude/sessions/*.jsonl | tail -5
# Verify fresh probes create JSONL files

# Check sessions_history is populated:
cat /home/ubuntu/.openclaw/agents/claude/sessions/sessions.json | \
  python3 -c "import json,sys; data=json.load(sys.stdin); \
  [print(k, v.get('sessionFile','NONE')) for k,v in list(data.items())[-3:]]"
```

**Step 5 — Verify `runtimeMs` fix:**

```bash
# Run a gemini probe that triggers timeout + fallback
# Then check subagents list output
openclaw subagents list 2>/dev/null | grep -E "runtimeMs|runtime"
# Expect: no negative values
```

---

## 3. Code-Level Fix Proposals

### Fix A — Expose errors in Patch B (prerequisite for all other fixes)

**File**: `subagent-registry-CkqrXKq4.js:39821`

```diff
- if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch {} }
+ if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch(e) { log$11.warn(`[cli-inject] chat.inject failed for ${params.sessionKey}: ${String(e)}`); } }
```

**Ordering constraint**: Apply before any other fix. This gives you diagnostic data immediately on next run.

---

### Fix B — Replace `callGatewayTool` with direct `appendAssistantMessageToSessionTranscript` (recommended primary fix)

Bypasses the gateway HTTP round-trip entirely. `appendAssistantMessageToSessionTranscript` is already imported in `subagent-registry-CkqrXKq4.js` as `r` (line 29 import). Direct call avoids auth token issues completely.

**File**: `subagent-registry-CkqrXKq4.js:39821`

```diff
- if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch {} }
+ if (cliText && params.sessionKey) {
+   try {
+     await appendAssistantMessageToSessionTranscript({
+       agentId: params.agentId,
+       sessionKey: params.sessionKey,
+       text: cliText
+     });
+   } catch(e) {
+     log$11.warn(`[cli-inject] transcript write failed for ${params.sessionKey}: ${String(e)}`);
+   }
+ }
```

**Idempotency**: `appendAssistantMessageToSessionTranscript` writes a new message each call. If called twice (e.g., due to retry), you get two messages. Guard: wrap in a `let injected = false; if (!injected) { injected = true; ... }` flag within the closure scope.

**Ordering constraint**: Must run after `runCliAgent` completes and before `emitAgentEvent({phase: "end"})`. Current Patch B position satisfies this.

---

### Fix C — Use `callGatewayLeastPrivilege` instead of `callGatewayTool` (alternative if Fix B is not preferred)

If staying with the HTTP approach, `callGatewayLeastPrivilege` (imported from `./call-DaJKh-6e.js`) resolves the token from the running config internally. Replace:

```diff
- await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText});
+ await callGatewayLeastPrivilege("chat.inject", {sessionKey: params.sessionKey, message: cliText});
```

Check the exact signature of `callGatewayLeastPrivilege` in the dist before applying — the param order may differ.

---

### Fix D — Clamp `runtimeMs` at line 21829 (runtimeMs negative bug)

**File**: `subagent-registry-CkqrXKq4.js:21829`

Find the exact pattern:
```
(entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt)
```

```diff
- (entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt)
+ Math.max(0, (entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt))
```

**Stable anchor for search**: This appears inside a `mapRuns` callback in the `subagents list` handler. The pattern `entry.endedAt ?? now` is unique enough to locate it. Verify only one occurrence before replacing.

---

## 4. Dist/Minified Targeting Strategy

**Active files (confirmed by gateway process inspection):**
- `gateway-cli-CuFEx2ht.js` — loaded via `register.subclis-GK5pfSQG.js`
- `subagent-registry-CkqrXKq4.js` — contains all functions to patch

**Inactive (do NOT re-patch):**
- `gateway-cli-vk3t7zJU.js` — has backup `.bak`, not loaded
- `reply-DhtejUNZ.js` — has backup `.bak`, not loaded

**Finding anchors in minified code:**

For any target pattern, use the following stable anchors:

```bash
# Fix B — find appendAssistantMessageToSessionTranscript call site:
grep -n "chat.inject.*sessionKey.*params.sessionKey" \
  /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js

# Fix D — find unclamped runtimeMs:
grep -n "endedAt.*now.*startedAt.*createdAt" \
  /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js

# Verify createIfMissing:true is in place (Patch A):
grep -c "createIfMissing: true" \
  /usr/lib/node_modules/openclaw/dist/gateway-cli-CuFEx2ht.js
# Expected: 3 (2 original + 1 patched)
```

**Re-apply instructions after an openclaw package update:**

1. Check file hashes first — if `CuFEx2ht` and `CkqrXKq4` hashes change, the patches are gone
2. Re-verify anchors with the grep commands above
3. Apply patches via `sudo python3 -c "..."` (node_modules requires root)
4. Use `config.apply` RPC to graceful-restart — never `openclaw gateway stop`

**Pre-patch backup command:**
```bash
sudo cp /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js \
  /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js.bak.$(date +%s)
```

---

## 5. Test Matrix + Definition of Done

| Probe | Provider | Expected post-fix | Verification |
|---|---|---|---|
| fresh-claude-1 | claude-sonnet-openclaw | `sessionFile_exists: True`, JSONL has assistant message, `sessions_history` non-empty | `cat sessions.json \| python3 -c "..."` + read JSONL |
| fresh-gemini-1 | gemini-cli | `sessionFile_exists: True`, JSONL has assistant message | Same |
| fresh-kimi-1 | kimi (if configured) | `sessionFile_exists: True` | Same |
| fresh-deepseek-1 | deepseek-code | `sessionFile_exists: True` | Same |
| gemini-timeout-1 | gemini-cli (short timeout) | Fallback fires, JSONL contains fallback output OR original output, `runtimeMs >= 0` | `subagents list \| grep runtimeMs` |
| empty-output-1 | any CLI backend with empty stdout | No crash, `sessions_history: []` is acceptable, no error in logs | Gateway log shows no unhandled exception |

**Definition of Done:**

1. `[patch-b-inject]` log lines appear in gateway log for every CLI subagent run
2. All "fresh" probes in the matrix above have `sessionFile_exists: True`
3. `readLatestSubagentOutput(sessionKey)` returns non-empty string for all passing probes
4. `runSubagentAnnounceFlow` produces a non-`"(no output)"` findings string in the announce message
5. `subagents list` shows `runtimeMs >= 0` for all rows (zero is allowed for instant runs)
6. No regression: embedded PI agents (blockrun/auto) still deliver results normally

---

## 6. Rollback + Risk Notes

**Rollback procedure:**

```bash
# Restore subagent-registry:
sudo cp /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js.bak \
  /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js

# Restore gateway-cli (if Patch A needs rollback):
sudo cp /usr/lib/node_modules/openclaw/dist/gateway-cli-CuFEx2ht.js.bak \
  /usr/lib/node_modules/openclaw/dist/gateway-cli-CuFEx2ht.js

# Graceful restart:
curl -s -X POST http://localhost:18789 \
  -H "Content-Type: application/json" \
  -d '{"method":"config.apply","params":{}}'
```

**Risk: Double-write if retry occurs**
If `runAgentTurnWithFallback` is retried (transient HTTP error path at `TRANSIENT_HTTP_RETRY_DELAY_MS`), the CLI run may run again and write a second message to the JSONL. The `appendAssistantMessageToSessionTranscript` call would append a duplicate. Mitigation: the `injected` flag pattern described in Fix B guards this within a single closure invocation; across retries, the second run would write a second (accurate) output which is acceptable.

**Risk: `createIfMissing: true` JSONL creation races with session archival**
If the session is being archived/deleted concurrently, a new JSONL might be created at the old path and then orphaned. Low probability in normal operation; acceptable risk for a debugging fix.

**Risk: Gateway restart timing**
`config.apply` triggers a graceful restart. There is a window (~500ms) where in-flight subagent runs may lose their lifecycle "end" event. If a run is in progress when restart fires, its JSONL write will still complete (write happens before lifecycle end emission), but the announce flow may not see it. Schedule restarts only when `subagents list` shows no active runs.

**Monitoring signals to watch:**
- `[patch-b-inject]` in gateway log: confirms the code path is executing
- `sessionFile_exists: True` in post-run session inspection: confirms JSONL written
- `sessions_history` non-empty in subagent result: confirms end-to-end delivery
- `runtimeMs < 0` in `subagents list` output: confirms Fix D was not applied or regressed

# CLI Subagent Transcript Fix — Engineering Analysis

_Generated 2026-03-05. Evidence: claude probe `ba87eb8b`, gemini timeout probe `f13c6d2d`, gemini done probe `8af3c941`._

---

## 1. Root-Cause Hypotheses — Ranked by Probability

### H1 — `try {} catch {}` completely silences Patch B failures (CONFIRMED structure, high certainty)

**File**: `subagent-registry-CkqrXKq4.js:39821`
**Evidence**: The injected line is:
```js
if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch {} }
```
There is zero error surfacing. Any HTTP error, auth rejection, "session not found", or thrown exception disappears silently. We cannot determine the actual failure mode without instrumenting the catch.

**Impact**: This is the reason we have no diagnostic signal. Without logging, every downstream hypothesis looks the same from the outside (no JSONL written, no error).

---

### H2 — `callGatewayTool("chat.inject", {}, ...)` sends request with `token: undefined` (HIGH probability root cause of auth failure)

**File**: `subagent-registry-CkqrXKq4.js:13500-13518`
`resolveGatewayOptions$1({})` with empty opts:
- No `opts.gatewayUrl` → `validatedOverride = undefined`
- No `opts.gatewayToken` → `explicitToken = undefined`
- `token = undefined` (no explicitToken, no override target token)

The HTTP call in `callGateway` then fires as:
```
POST http://localhost:18789
Authorization: Bearer undefined   <- or no header at all
```

The gateway's auth middleware will reject this with an auth error — swallowed by `try {} catch {}`.

**Fix**: Pass `callGatewayLeastPrivilege` instead, or pass opts that resolve to a valid operator token. The function `callGatewayLeastPrivilege` (also imported from `./call-DaJKh-6e.js`) resolves the operator token from the running config internally.

---

### H3 — `loadSessionEntry(sessionKey)` returns `null` for subagent sessions (MEDIUM probability, secondary)

**File**: `gateway-cli-CuFEx2ht.js:11449`
```js
const { cfg, storePath, entry } = loadSessionEntry(rawSessionKey);
const sessionId = entry?.sessionId;
if (!sessionId || !storePath) {
    respond(false, void 0, errorShape(ErrorCodes.INVALID_REQUEST, "session not found"));
    return;
}
```

For subagent sessions with key `agent:claude:subagent:ba87eb8b-...`, the session MUST be in `sessions.json` before `runCliAgent` completes. The spawning path writes it before the run starts, so this should not be a timing race in normal flow. However, if the subagent runs in an isolated context where `sessions.json` isn't flushed yet (file-lock contention, async I/O lag), this could fail.

**Confidence**: Medium — only becomes the cause if H2 is ruled out.

---

### H4 — The probe runs (ba87eb8b, 8af3c941) predate the patches (CONFIRMED, explains the evidence)

Both probes were run at ~03:56 and ~03:58 respectively. Patches were applied during the debugging session that followed. The `sessionFile_exists: False` evidence for these probes reflects their pre-patch state. **These probes cannot be used to validate whether Patch B works.** A fresh post-patch probe has not been run.

**Impact**: The entire "persistent empty transcripts despite Patch B" narrative is based on stale evidence. We do not actually know if Patch B fires correctly for new runs.

---

### H5 — `runtimeMs` negative bug: fallback `startedAt` overwrite (CONFIRMED mechanism)

**File**: `subagent-registry-CkqrXKq4.js:21829`
```js
// UNCLAMPED:
(entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt)
```

For gemini probe `f13c6d2d` (timeout): when gemini-cli times out, `runWithModelFallback` triggers `blockrun/auto` as fallback. The fallback emits a new lifecycle `phase: "start"` event which overwrites `entry.startedAt` with the fallback's start timestamp. `entry.endedAt` was already set from the original run's `phase: "end"` event. So `endedAt < startedAt` → negative `runtimeMs`.

The clamped path in `buildCompactAnnounceStatsLine` at line 84302 uses `Math.max(0, ...)` and is fine. Only the `subagents list` display path at 21829 is unclamped.

---

## 2. Verification Plan

**Step 1 — Instrument Patch B to surface the error:**

```bash
# Find exact line of the catch block
grep -n "callGatewayTool.*chat.inject" /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js
```

Edit line ~39821 from:
```js
} catch {} }
```
to:
```js
} catch(e) { console.error("[patch-b-inject] chat.inject failed:", String(e)); } }
```

Then restart the gateway:
```bash
# Use config.apply RPC to graceful-restart (do NOT use CLI stop/start)
curl -s -X POST http://localhost:18789 \
  -H "Content-Type: application/json" \
  -d '{"method":"config.apply","params":{}}'
```

**Step 2 — Run a fresh CLI probe and tail the gateway log:**

```bash
# Watch for the error line in real-time
journalctl -f -u openclaw 2>/dev/null || tail -f /var/log/openclaw/gateway.log &

# Run a minimal probe via the CLI backend
# (use whatever mechanism triggers a CLI backend subagent run)
```

Expected output if H2 (token auth): `[patch-b-inject] chat.inject failed: Error: 401 Unauthorized`
Expected output if H3 (session not found): `[patch-b-inject] chat.inject failed: Error: session not found`

**Step 3 — Verify token resolution path:**

```bash
# In the gateway process context, check what token would be resolved
node -e "
const {loadConfig} = require('/usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js');
const cfg = loadConfig();
console.log('token:', cfg?.gateway?.token ? 'PRESENT' : 'MISSING');
"
```

**Step 4 — Post-fix verification: Run new probes and check:**

```bash
# After applying the fix below:
ls -la /home/ubuntu/.openclaw/agents/claude/sessions/*.jsonl | tail -5
# Verify fresh probes create JSONL files

# Check sessions_history is populated:
cat /home/ubuntu/.openclaw/agents/claude/sessions/sessions.json | \
  python3 -c "import json,sys; data=json.load(sys.stdin); \
  [print(k, v.get('sessionFile','NONE')) for k,v in list(data.items())[-3:]]"
```

**Step 5 — Verify `runtimeMs` fix:**

```bash
# Run a gemini probe that triggers timeout + fallback
# Then check subagents list output
openclaw subagents list 2>/dev/null | grep -E "runtimeMs|runtime"
# Expect: no negative values
```

## 3. Code-Level Fix Proposals

### Fix A — Expose errors in Patch B (prerequisite for all other fixes)

**File**: `subagent-registry-CkqrXKq4.js:39821`

```diff
- if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch {} }
+ if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch(e) { log$11.warn(`[cli-inject] chat.inject failed for ${params.sessionKey}: ${String(e)}`); } }
```

**Ordering constraint**: Apply before any other fix. This gives you diagnostic data immediately on next run.

---

### Fix B — Replace `callGatewayTool` with direct `appendAssistantMessageToSessionTranscript` (recommended primary fix)

Bypasses the gateway HTTP round-trip entirely. `appendAssistantMessageToSessionTranscript` is already imported in `subagent-registry-CkqrXKq4.js` as `r` (line 29 import). Direct call avoids auth token issues completely.

**File**: `subagent-registry-CkqrXKq4.js:39821`

```diff
- if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch {} }
+ if (cliText && params.sessionKey) {
+   try {
+     await appendAssistantMessageToSessionTranscript({
+       agentId: params.agentId,
+       sessionKey: params.sessionKey,
+       text: cliText
+     });
+   } catch(e) {
+     log$11.warn(`[cli-inject] transcript write failed for ${params.sessionKey}: ${String(e)}`);
+   }
+ }
```

**Idempotency**: `appendAssistantMessageToSessionTranscript` writes a new message each call. If called twice (e.g., due to retry), you get two messages. Guard: wrap in a `let injected = false; if (!injected) { injected = true; ... }` flag within the closure scope.

**Ordering constraint**: Must run after `runCliAgent` completes and before `emitAgentEvent({phase: "end"})`. Current Patch B position satisfies this.

---

### Fix C — Use `callGatewayLeastPrivilege` instead of `callGatewayTool` (alternative if Fix B is not preferred)

If staying with the HTTP approach, `callGatewayLeastPrivilege` (imported from `./call-DaJKh-6e.js`) resolves the token from the running config internally. Replace:

```diff
- await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText});
+ await callGatewayLeastPrivilege("chat.inject", {sessionKey: params.sessionKey, message: cliText});
```

Check the exact signature of `callGatewayLeastPrivilege` in the dist before applying — the param order may differ.

---

### Fix D — Clamp `runtimeMs` at line 21829 (runtimeMs negative bug)

**File**: `subagent-registry-CkqrXKq4.js:21829`

Find the exact pattern:
```
(entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt)
```

```diff
- (entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt)
+ Math.max(0, (entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt))
```

**Stable anchor for search**: This appears inside a `mapRuns` callback in the `subagents list` handler. The pattern `entry.endedAt ?? now` is unique enough to locate it. Verify only one occurrence before replacing.

---

## 4. Dist/Minified Targeting Strategy

**Active files (confirmed by gateway process inspection):**
- `gateway-cli-CuFEx2ht.js` — loaded via `register.subclis-GK5pfSQG.js`
- `subagent-registry-CkqrXKq4.js` — contains all functions to patch

**Inactive (do NOT re-patch):**
- `gateway-cli-vk3t7zJU.js` — has backup `.bak`, not loaded
- `reply-DhtejUNZ.js` — has backup `.bak`, not loaded

**Finding anchors in minified code:**

For any target pattern, use the following stable anchors:

```bash
# Fix B — find appendAssistantMessageToSessionTranscript call site:
grep -n "chat.inject.*sessionKey.*params.sessionKey" \
  /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js

# Fix D — find unclamped runtimeMs:
grep -n "endedAt.*now.*startedAt.*createdAt" \
  /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js

# Verify createIfMissing:true is in place (Patch A):
grep -c "createIfMissing: true" \
  /usr/lib/node_modules/openclaw/dist/gateway-cli-CuFEx2ht.js
# Expected: 3 (2 original + 1 patched)
```

**Re-apply instructions after an openclaw package update:**

1. Check file hashes first — if `CuFEx2ht` and `CkqrXKq4` hashes change, the patches are gone
2. Re-verify anchors with the grep commands above
3. Apply patches via `sudo python3 -c "..."` (node_modules requires root)
4. Use `config.apply` RPC to graceful-restart — never `openclaw gateway stop`

**Pre-patch backup command:**
```bash
sudo cp /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js \
  /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js.bak.$(date +%s)
```

## 5. Test Matrix + Definition of Done

| Probe | Provider | Expected post-fix | Verification |
|---|---|---|---|
| fresh-claude-1 | claude-sonnet-openclaw | `sessionFile_exists: True`, JSONL has assistant message, `sessions_history` non-empty | `cat sessions.json \| python3 -c "..."` + read JSONL |
| fresh-gemini-1 | gemini-cli | `sessionFile_exists: True`, JSONL has assistant message | Same |
| fresh-kimi-1 | kimi (if configured) | `sessionFile_exists: True` | Same |
| fresh-deepseek-1 | deepseek-code | `sessionFile_exists: True` | Same |

| empty-output-1 | any CLI backend with empty stdout | No crash, `sessions_history: []` is acceptable, no error in logs | Gateway log shows no unhandled exception |

**Definition of Done:**

1. `[patch-b-inject]` log lines appear in gateway log for every CLI subagent run
2. All "fresh" probes in the matrix above have `sessionFile_exists: True`
3. `readLatestSubagentOutput(sessionKey)` returns non-empty string for all passing probes
4. `runSubagentAnnounceFlow` produces a non-`"(no output)"` findings string in the announce message
5. `subagents list` shows `runtimeMs >= 0` for all rows (zero is allowed for instant runs)
6. No regression: embedded PI agents (blockrun/auto) still deliver results normally

**Risk: Double-write if retry occurs**
If `runAgentTurnWithFallback` is retried (transient HTTP error path at `TRANSIENT_HTTP_RETRY_DELAY_MS`), the CLI run may run again and write a second message to the JSONL. The `appendAssistantMessageToSessionTranscript` call would append a duplicate. Mitigation: the `injected` flag pattern described in Fix B guards this within a single closure invocation; across retries, the second run would write a second (accurate) output which is acceptable.

**Risk: `createIfMissing: true` JSONL creation races with session archival**
If the session is being archived/deleted concurrently, a new JSONL might be created at the old path and then orphaned. Low probability in normal operation; acceptable risk for a debugging fix.

**Risk: Gateway restart timing**
`config.apply` triggers a graceful restart. There is a window (~500ms) where in-flight subagent runs may lose their lifecycle "end" event. If a run is in progress when restart fires, its JSONL write will still complete (write happens before lifecycle end emission), but the announce flow may not see it. Schedule restarts only when `subagents list` shows no active runs.

**Monitoring signals to watch:**
- `[patch-b-inject]` in gateway log: confirms the code path is executing
- `sessionFile_exists: True` in post-run session inspection: confirms JSONL written
- `sessions_history` non-empty in subagent result: confirms end-to-end delivery
- `runtimeMs < 0` in `subagents list` output: confirms Fix D was not applied or regressed

# CLI Subagent Transcript Fix — Engineering Analysis

_Generated 2026-03-05. Evidence: claude probe `ba87eb8b`, gemini timeout probe `f13c6d2d`, gemini done probe `8af3c941`._

---

## 1. Root-Cause Hypotheses — Ranked by Probability

### H1 — `try {} catch {}` completely silences Patch B failures (CONFIRMED structure, high certainty)

**File**: `subagent-registry-CkqrXKq4.js:39821`
**Evidence**: The injected line is:
```js
if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch {} }
```
There is zero error surfacing. Any HTTP error, auth rejection, "session not found", or thrown exception disappears silently. We cannot determine the actual failure mode without instrumenting the catch.

**Impact**: This is the reason we have no diagnostic signal. Without logging, every downstream hypothesis looks the same from the outside (no JSONL written, no error).

---

### H2 — `callGatewayTool("chat.inject", {}, ...)` sends request with `token: undefined` (HIGH probability root cause of auth failure)

**File**: `subagent-registry-CkqrXKq4.js:13500-13518`
`resolveGatewayOptions$1({})` with empty opts:
- No `opts.gatewayUrl` → `validatedOverride = undefined`
- No `opts.gatewayToken` → `explicitToken = undefined`
- `token = undefined` (no explicitToken, no override target token)

The HTTP call in `callGateway` then fires as:
```
POST http://localhost:18789
Authorization: Bearer undefined   <- or no header at all
```

The gateway's auth middleware will reject this with an auth error — swallowed by `try {} catch {}`.

**Fix**: Pass `callGatewayLeastPrivilege` instead, or pass opts that resolve to a valid operator token. The function `callGatewayLeastPrivilege` (also imported from `./call-DaJKh-6e.js`) resolves the operator token from the running config internally.

---

### H3 — `loadSessionEntry(sessionKey)` returns `null` for subagent sessions (MEDIUM probability, secondary)

**File**: `gateway-cli-CuFEx2ht.js:11449`
```js
const { cfg, storePath, entry } = loadSessionEntry(rawSessionKey);
const sessionId = entry?.sessionId;
if (!sessionId || !storePath) {
    respond(false, void 0, errorShape(ErrorCodes.INVALID_REQUEST, "session not found"));
    return;
}
```

For subagent sessions with key `agent:claude:subagent:ba87eb8b-...`, the session MUST be in `sessions.json` before `runCliAgent` completes. The spawning path writes it before the run starts, so this should not be a timing race in normal flow. However, if the subagent runs in an isolated context where `sessions.json` isn't flushed yet (file-lock contention, async I/O lag), this could fail.

**Confidence**: Medium — only becomes the cause if H2 is ruled out.

---

### H4 — The probe runs (ba87eb8b, 8af3c941) predate the patches (CONFIRMED, explains the evidence)

Both probes were run at ~03:56 and ~03:58 respectively. Patches were applied during the debugging session that followed. The `sessionFile_exists: False` evidence for these probes reflects their pre-patch state. **These probes cannot be used to validate whether Patch B works.** A fresh post-patch probe has not been run.

**Impact**: The entire "persistent empty transcripts despite Patch B" narrative is based on stale evidence. We do not actually know if Patch B fires correctly for new runs.

---

### H5 — `runtimeMs` negative bug: fallback `startedAt` overwrite (CONFIRMED mechanism)

**File**: `subagent-registry-CkqrXKq4.js:21829`
```js
// UNCLAMPED:
(entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt)
```

For gemini probe `f13c6d2d` (timeout): when gemini-cli times out, `runWithModelFallback` triggers `blockrun/auto` as fallback. The fallback emits a new lifecycle `phase: "start"` event which overwrites `entry.startedAt` with the fallback's start timestamp. `entry.endedAt` was already set from the original run's `phase: "end"` event. So `endedAt < startedAt` → negative `runtimeMs`.

The clamped path in `buildCompactAnnounceStatsLine` at line 84302 uses `Math.max(0, ...)` and is fine. Only the `subagents list` display path at 21829 is unclamped.

---

## 2. Verification Plan

**Step 1 — Instrument Patch B to surface the error:**

```bash
# Find exact line of the catch block
grep -n "callGatewayTool.*chat.inject" /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js
```

Edit line ~39821 from:
```js
} catch {} }
```
to:
```js
} catch(e) { console.error("[patch-b-inject] chat.inject failed:", String(e)); } }
```

Then restart the gateway:
```bash
# Use config.apply RPC to graceful-restart (do NOT use CLI stop/start)
curl -s -X POST http://localhost:18789 \
  -H "Content-Type: application/json" \
  -d '{"method":"config.apply","params":{}}'
```

**Step 2 — Run a fresh CLI probe and tail the gateway log:**

```bash
# Watch for the error line in real-time
journalctl -f -u openclaw 2>/dev/null || tail -f /var/log/openclaw/gateway.log &

# Run a minimal probe via the CLI backend
# (use whatever mechanism triggers a CLI backend subagent run)
```

Expected output if H2 (token auth): `[patch-b-inject] chat.inject failed: Error: 401 Unauthorized`
Expected output if H3 (session not found): `[patch-b-inject] chat.inject failed: Error: session not found`

**Step 3 — Verify token resolution path:**

```bash
# In the gateway process context, check what token would be resolved
node -e "
const {loadConfig} = require('/usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js');
const cfg = loadConfig();
console.log('token:', cfg?.gateway?.token ? 'PRESENT' : 'MISSING');
"
```

**Step 4 — Post-fix verification: Run new probes and check:**

```bash
# After applying the fix below:
ls -la /home/ubuntu/.openclaw/agents/claude/sessions/*.jsonl | tail -5
# Verify fresh probes create JSONL files

# Check sessions_history is populated:
cat /home/ubuntu/.openclaw/agents/claude/sessions/sessions.json | \
  python3 -c "import json,sys; data=json.load(sys.stdin); \
  [print(k, v.get('sessionFile','NONE')) for k,v in list(data.items())[-3:]]"
```

**Step 5 — Verify `runtimeMs` fix:**

```bash
# Run a gemini probe that triggers timeout + fallback
# Then check subagents list output
openclaw subagents list 2>/dev/null | grep -E "runtimeMs|runtime"
# Expect: no negative values
```

---

## 3. Code-Level Fix Proposals

### Fix A — Expose errors in Patch B (prerequisite for all other fixes)

**File**: `subagent-registry-CkqrXKq4.js:39821`

```diff
- if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch {} }
+ if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch(e) { log$11.warn(`[cli-inject] chat.inject failed for ${params.sessionKey}: ${String(e)}`); } }
```

**Ordering constraint**: Apply before any other fix. This gives you diagnostic data immediately on next run.

---

### Fix B — Replace `callGatewayTool` with direct `appendAssistantMessageToSessionTranscript` (recommended primary fix)

Bypasses the gateway HTTP round-trip entirely. `appendAssistantMessageToSessionTranscript` is already imported in `subagent-registry-CkqrXKq4.js` as `r` (line 29 import). Direct call avoids auth token issues completely.

**File**: `subagent-registry-CkqrXKq4.js:39821`

```diff
- if (cliText && params.sessionKey) { try { await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText}); } catch {} }
+ if (cliText && params.sessionKey) {
+   try {
+     await appendAssistantMessageToSessionTranscript({
+       agentId: params.agentId,
+       sessionKey: params.sessionKey,
+       text: cliText
+     });
+   } catch(e) {
+     log$11.warn(`[cli-inject] transcript write failed for ${params.sessionKey}: ${String(e)}`);
+   }
+ }
```

**Idempotency**: `appendAssistantMessageToSessionTranscript` writes a new message each call. If called twice (e.g., due to retry), you get two messages. Guard: wrap in a `let injected = false; if (!injected) { injected = true; ... }` flag within the closure scope.

**Ordering constraint**: Must run after `runCliAgent` completes and before `emitAgentEvent({phase: "end"})`. Current Patch B position satisfies this.

---

### Fix C — Use `callGatewayLeastPrivilege` instead of `callGatewayTool` (alternative if Fix B is not preferred)

If staying with the HTTP approach, `callGatewayLeastPrivilege` (imported from `./call-DaJKh-6e.js`) resolves the token from the running config internally. Replace:

```diff
- await callGatewayTool("chat.inject", {}, {sessionKey: params.sessionKey, message: cliText});
+ await callGatewayLeastPrivilege("chat.inject", {sessionKey: params.sessionKey, message: cliText});
```

Check the exact signature of `callGatewayLeastPrivilege` in the dist before applying — the param order may differ.

---

### Fix D — Clamp `runtimeMs` at line 21829 (runtimeMs negative bug)

**File**: `subagent-registry-CkqrXKq4.js:21829`

Find the exact pattern:
```
(entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt)
```

```diff
- (entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt)
+ Math.max(0, (entry.endedAt ?? now) - (entry.startedAt ?? entry.createdAt))
```

**Stable anchor for search**: This appears inside a `mapRuns` callback in the `subagents list` handler. The pattern `entry.endedAt ?? now` is unique enough to locate it. Verify only one occurrence before replacing.

---

## 4. Dist/Minified Targeting Strategy

**Active files (confirmed by gateway process inspection):**
- `gateway-cli-CuFEx2ht.js` — loaded via `register.subclis-GK5pfSQG.js`
- `subagent-registry-CkqrXKq4.js` — contains all functions to patch

**Inactive (do NOT re-patch):**
- `gateway-cli-vk3t7zJU.js` — has backup `.bak`, not loaded
- `reply-DhtejUNZ.js` — has backup `.bak`, not loaded

**Finding anchors in minified code:**

For any target pattern, use the following stable anchors:

```bash
# Fix B — find appendAssistantMessageToSessionTranscript call site:
grep -n "chat.inject.*sessionKey.*params.sessionKey" \
  /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js

# Fix D — find unclamped runtimeMs:
grep -n "endedAt.*now.*startedAt.*createdAt" \
  /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js

# Verify createIfMissing:true is in place (Patch A):
grep -c "createIfMissing: true" \
  /usr/lib/node_modules/openclaw/dist/gateway-cli-CuFEx2ht.js
# Expected: 3 (2 original + 1 patched)
```

**Re-apply instructions after an openclaw package update:**

1. Check file hashes first — if `CuFEx2ht` and `CkqrXKq4` hashes change, the patches are gone
2. Re-verify anchors with the grep commands above
3. Apply patches via `sudo python3 -c "..."` (node_modules requires root)
4. Use `config.apply` RPC to graceful-restart — never `openclaw gateway stop`

**Pre-patch backup command:**
```bash
sudo cp /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js \
  /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js.bak.$(date +%s)
```

## 5. Test Matrix + Definition of Done

| Probe | Provider | Expected post-fix | Verification |
|---|---|---|---|
| fresh-claude-1 | claude-sonnet-openclaw | `sessionFile_exists: True`, JSONL has assistant message, `sessions_history` non-empty | `cat sessions.json \| python3 -c "..."` + read JSONL |
| fresh-gemini-1 | gemini-cli | `sessionFile_exists: True`, JSONL has assistant message | Same |
| fresh-kimi-1 | kimi (if configured) | `sessionFile_exists: True` | Same |
| fresh-deepseek-1 | deepseek-code | `sessionFile_exists: True` | Same |
| gemini-timeout-1 | gemini-cli (short timeout) | Fallback fires, JSONL contains fallback output OR original output, `runtimeMs >= 0` | `subagents list \| grep runtimeMs` |
| empty-output-1 | any CLI backend with empty stdout | No crash, `sessions_history: []` is acceptable, no error in logs | Gateway log shows no unhandled exception |

**Definition of Done:**

1. `[patch-b-inject]` log lines appear in gateway log for every CLI subagent run
2. All "fresh" probes in the matrix above have `sessionFile_exists: True`
3. `readLatestSubagentOutput(sessionKey)` returns non-empty string for all passing probes
4. `runSubagentAnnounceFlow` produces a non-`"(no output)"` findings string in the announce message
5. `subagents list` shows `runtimeMs >= 0` for all rows (zero is allowed for instant runs)
6. No regression: embedded PI agents (blockrun/auto) still deliver results normally

---

## 6. Rollback + Risk Notes

**Rollback procedure:**

```bash
# Restore subagent-registry:
sudo cp /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js.bak \
  /usr/lib/node_modules/openclaw/dist/subagent-registry-CkqrXKq4.js

# Restore gateway-cli (if Patch A needs rollback):
sudo cp /usr/lib/node_modules/openclaw/dist/gateway-cli-CuFEx2ht.js.bak \
  /usr/lib/node_modules/openclaw/dist/gateway-cli-CuFEx2ht.js

# Graceful restart:
curl -s -X POST http://localhost:18789 \
  -H "Content-Type: application/json" \
  -d '{"method":"config.apply","params":{}}'
```

**Risk: Double-write if retry occurs**
If `runAgentTurnWithFallback` is retried (transient HTTP error path at `TRANSIENT_HTTP_RETRY_DELAY_MS`), the CLI run may run again and write a second message to the JSONL. The `appendAssistantMessageToSessionTranscript` call would append a duplicate. Mitigation: the `injected` flag pattern described in Fix B guards this within a single closure invocation; across retries, the second run would write a second (accurate) output which is acceptable.

**Risk: `createIfMissing: true` JSONL creation races with session archival**
If the session is being archived/deleted concurrently, a new JSONL might be created at the old path and then orphaned. Low probability in normal operation; acceptable risk for a debugging fix.

**Risk: Gateway restart timing**
`config.apply` triggers a graceful restart. There is a window (~500ms) where in-flight subagent runs may lose their lifecycle "end" event. If a run is in progress when restart fires, its JSONL write will still complete (write happens before lifecycle end emission), but the announce flow may not see it. Schedule restarts only when `subagents list` shows no active runs.

**Monitoring signals to watch:**
- `[patch-b-inject]` in gateway log: confirms the code path is executing
- `sessionFile_exists: True` in post-run session inspection: confirms JSONL written
- `sessions_history` non-empty in subagent result: confirms end-to-end delivery
- `runtimeMs < 0` in `subagents list` output: confirms Fix D was not applied or regressed
