v0.9.0

pocx_doctor v0.9.0 — Initial release

Graphical sample-based health checker for PoCX plot files. Spot-checks a .pocx plot in seconds — orders of magnitude faster than a full verifier sweep — and shows the result as a colour-coded grid.

What it does

• Statistical sampling: 64×48 grid (3 072 cells) over the nonce/scoop plane, 1 / 2 / 4 probes per cell depending on thoroughness.
• Pinned canary probes: first and last nonces are always probed so early- and late-write corruption is caught reliably.
• Tail-magic detection: paused / aborted plots are recognised and reported correctly instead of flagged as broken.
• SIMD auto-dispatch: SSE2 / AVX / AVX2 / AVX512 selected at startup.
• Single & batch modes: one file, or every .pocx in a folder.
• JSON + standalone HTML reports for sharing per-plot results.

Quick start

1. Download the archive for your platform below.
2. Extract and launch:
   • Windows — double-click `pocx_doctor.exe`
   • Linux / macOS — `./pocx_doctor`
3. Open file… or Open folder… → pick thoroughness (Quick / Normal / Deep) → Start.
4. The grid fills as probes complete; the health badge sits beside it.
