# T02: Added "Commit" row to version metadata panel on TechniquePage — renders abbreviated 7-char git SHA using existing hash-value monospace styling, hidden when SHA is "unknown"

**Added "Commit" row to version metadata panel on TechniquePage — renders abbreviated 7-char git SHA using existing hash-value monospace styling, hidden when SHA is "unknown"**

## What Happened

Edited frontend/src/pages/TechniquePage.tsx on ub01, inserting a new conditional block in the version-metadata__grid after the existing prompt_hashes section. The block checks for git_commit_sha key in pipeline_metadata, filters out the "unknown" fallback, and renders a "Commit" label with the first 7 characters of the SHA inside a code tag using the existing version-metadata__hash-value class for consistent monospace styling. Build passes cleanly.

## Verification

Ran npm run build (tsc + vite) in the frontend directory on ub01 — zero TypeScript errors, clean production build with 46 modules transformed.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `ssh ub01 'cd /vmPool/r/repos/xpltdco/chrysopedia/frontend && npm run build 2>&1 | tail -5'` | 0 | ✅ pass | 5000ms |


## Deviations

Added a filter for !== "unknown" — showing a literal "unknown" string in the UI is meaningless, so the SHA only renders when a real commit hash was captured at build time.

## Known Issues

None.
