[Bug] Auto-continue disabled after five_hour rate limit reset with multiple sessions

Bug Description

Summary

With /config → "Continue automatically at usage limit" enabled, a CLI session stopped at a five_hour usage limit and never retried after the reset time. The process stayed alive the whole time; the session only resumed when I typed into it manually the next morning, ~8.5 hours later.

Environment

• Claude Code 2.1.261
• macOS (Apple Silicon)
• entrypoint: cli, launched as: exec caffeinate -dims claude --enable-auto-mode
• Model: claude-opus-5

Timeline (JST)

| Time | Event |
|---|---|
| 00:45:06 | Session A (e8d777e2) hits limit, HTTP 429 |
| 00:49:10 | Session B (991e4133, sessionKind: bg) hits same limit |
| 01:20 | resetsAt (1788625200) |
| 01:20–09:41 | No records at all in either session JSONL |
| 09:41:12 / 09:41:24 | Both resumed — by me typing into the still-running sessions |

Gap: 536 min / 532 min with zero records, spanning the reset.

Rate limit payload

{
  "status": "rejected",
  "resetsAt": 1788625200,
  "unifiedRateLimitFallbackAvailable": false,
  "rateLimitType": "five_hour",
  "overageStatus": "rejected",
  "overageDisabledReason": "member_zero_credit_limit",
  "isUsingOverage": false
}

Ruled out

• Sleep: none. pmset -g log shows powerd's "Prevent sleep while display is on" assertion (same id 0x10000944f) held continuously across the window; no Sleep/Wake/DarkWake events.
• Crash: ~/Library/Logs/DiagnosticReports/ has no entries for the window.
• Network: kernel TCP + mDNSResponder logs show the Claude process connecting every ~20s throughout.
• Process death: the CLI process was alive — I typed into the same running session the next morning and it continued.

Expected

After resetsAt, the interrupted turn is re-sent automatically.

Actual

Nothing happens. The session sits idle indefinitely until manual input.

Possibly relevant

Two sessions shared the same five-hour window, one of them sessionKind: bg. Both failed to auto-resume.
