Actual app, same native recorded DB, OpenCode only, Tokens, 30 days, scroll top, light/dark, sidebar collapsed and all eight PNGs visually inspected. Earlier unsafe stills were replaced locally and never uploaded.

| Metric | Before | After | Difference |
|---|---:|---:|---:|
| Processed tokens | 4,500 | 1,500 | −3,000 |
| Uncached input | 3,000 | 1,000 | −2,000 |
| Cached input | 900 | 300 | −600 |
| Output | 600 | 200 | −400 |
| Reported fixture cost | $0.03 | $0.01 | −$0.02 |
| Contributing sessions | 3 | 1 | −2 |

Native OpenCode 2.1.2 fork and fork-of-fork APIs copied a synthetic imported response. No billed model call. Chart axis auto-scales; session count reduction is expected. No UI code changed.

Actual window.innerWidth/innerHeight evaluated for every capture: 1440×900 and 390×900 CSS pixels. Independent follow-up evaluation confirms both, devicePixelRatio=2. Native preview saved desktop PNGs at 1280×800 (resampled by preview), narrow PNGs at 780×1800. No manual resizing/upscaling. These are CSS viewport labels, not claims of 1440-pixel PNGs.

Stable native DB backup SHA-256: `94df498297598a39fbe14a4c83953c60dac162f976f94c07116fb70b383066e1`.
Baseline reader SHA-256: `0d920de04b21310c26eb955e82eefeec964dd2cb9bb8697ea053c7d7b864deaf`.
Fixed reader SHA-256: `e07d672337f22d915c22c5408dae1a936ebc113fd4425d20e7bcae55960dd0b3`.
Live native DB and backup have identical ordered session/message row hashes; quick_check=ok. Full image SHA-256, capture timestamps, evaluated viewport, theme, visible text, source SHA, and raster differences are in manifest.

Pixel differences: desktop light 1,966/1,024,000 (0.1920%), desktop dark 1,944 (0.1898%); narrow light 6,338/1,404,000 (0.4514%), narrow dark 6,322 (0.4503%). Includes expected axis/text changes; not a performance benchmark.

Source restored to exact head, git status clean, actual app returned to fixed 1.50K / $0.01 / 1 session. No commits, process starts/kills, gh commands, issue comments, or PR writes. Publication gate: issue and all comments fetched through cafe immediately before upload; zero comments, no last-24h MEMBER/OWNER comment. Public uploads only via ghdrop skill.

Unverified: native mobile, Electron, remote/relay/tunnel, other providers, billed model requests, performance. Narrow viewport is responsive web, not native-mobile verification. Proof-pass1 is the unchanged earlier audit and retains local paths to its separate 1280×800 stills; the eight public stills below are this capture stage. reader-main.json in transcript is explicitly the earlier TWO-copy baseline, not the three-copy screenshot baseline.

Model: gpt-6.1-sol. Harness: Codex.
