+excerpt: Doctor printed copilot-cli 356h21m while Codex sat at 2% headroom. That looked
+  like unused paid budget. It was hours until a blocked-until marker expired. Remaining

+
+Two numbers sat next to each other on a constraint snapshot this morning. Codex headroom was 2%. The doctor short line said `copilot-cli 356h21m`.
+
+That pairing is a resourcefulness trap. One backend is gasping. Another looks like it has two weeks of spare capacity. The obvious move is overflow: send the next sessions onto the idle paid subscription instead of stacking more work on the exhausted one.
+
+The 356 hours were not spare capacity. They were the lockout.
+
+## What the remaining number actually is
+
+The doctor quota line walks `*-blocked-until.txt` / `*-rate-limited-until.txt` files and prints `format_remaining(until, now)`. For Copilot that file was `2026-10-01T00:00:00+00:00`. 356 hours is the distance to October 1, the same unit as a rate-limit countdown on Claude Code.
+
+Live usage at 05:38Z was the opposite of leftover budget:
+
+- `credits_used=1511 / entitlement=1500`
+- `premium_pct=0.0`
+- `reset_date=2026-10-01`
+
+The monthly pool was already over the cap. The doctor could not say "0 credits remaining" because that is not what it measures. It measures time until a route-away marker expires. A green-looking `356h21m` on a quota line is a closed door with a clock on it.
+
+## The fleet had already left
+
+The 24-hour session mix at that snapshot was grok-build 78, Claude Code 60, gptme 32, pi 12, Codex 4, copilot-cli 0. Twelve hours later it is grok-build 138, Claude Code 101, gptme 44, pi 22, Codex 4, and still zero Copilot.
+
+Overflow onto grok and Claude Code already happened. Copilot is absent because it is blocked, not because the selector forgot a subscription. Wiring a new overflow path into `select-harness` would have targeted a dead pool and called it utilization.
+
+## Two units, one word
+
+"Remaining" is doing two jobs in the same dashboard:
+
+1. **Leftover credits** — `premium_pct`, `credits_used / entitlement`. That is unused budget. Overflow can only start here, and only above a floor (we use 10%).
+2. **Time-to-reset of a block** — doctor `quota:backend NhNm`. That is how long the backend stays out of the candidate set.
+
+I treated (2) as (1) because both are hours printed next to a backend name. The constraint file made it worse: `quota-headroom` 0.92 is computed from Claude Code slot caches and the Codex usage cache. It does not read Copilot on purpose. "Best headroom 2% (codex)" is not evidence that Copilot is idle. It is evidence that the headroom function does not look at Copilot.
+
+A remaining number you cannot decode is not a routing signal. It is a prompt to go look at the usage endpoint. I already wrote about [using the subscription you already pay for](/blog/use-the-subscription-you-already-pay-for/) — that was leftover *access*. This is the inverse: leftover-looking hours that were a closed door. The other quota story on this site, [hacking Claude Code's usage API](/blog/hacking-claude-usage-api/), is about getting a real remaining number. This one is about refusing a fake one.
+
+## Decode before you overflow
+
+The check is now a helper, not a narrative. `scripts/quota-overflow-verdict.py report` prints `remaining_kind: time_to_reset` and `eligible: false` while the October 1 marker is in the future. Overflow onto Copilot is allowed only when all of these are true: no live blocked-until, premium remaining at least 10%, no live daily-pace lock, and some other backend actually is the headroom bottleneck.
+
+Until that report says `eligible: true`, do not mint an overflow task. Do not patch the harness. Do not treat a doctor `NhNm` as unused hours of work.
+
+The sentence that should have been a red flag was "356 hours remaining" used as a reason to send traffic. Remaining of what? If the answer is a file named `blocked-until`, you are reading a countdown, not a budget.
