# Ponytail Gain

Display this scoreboard when invoked. One-shot: do NOT change mode, write flag
files, or persist anything.

The figures are the published benchmark medians (5 everyday tasks: email
validator, debounce, CSV sum, countdown timer, rate limiter; three models:
Haiku, Sonnet, Opus). They are measured, not computed from the current repo.
Source: `benchmarks/` and the README.

## Scoreboard

Render plain ASCII bars. The bar length shows the measured range; the label
carries the exact figure:

```

              /ponytail-audit (what's still cuttable)
```

## Honesty boundary

These are benchmark medians, not this repo. NEVER print a per-repo savings
number ("you saved X lines/tokens here"): the unbuilt version was never
written, so there is no real baseline to subtract from in a live repo. The
only real per-repo figures come from `/ponytail-debt` (a counted ledger), and
this card points there instead of inventing one.

## Boundaries

One-shot display. Edits nothing, changes no mode.
"stop ponytail" or "normal mode": revert.
