The SVGR + svgo config decides how every icon rasterizes, and nothing checked it. Six cases pin the parts that silently change rendering: mono icons follow the consumer's colour, colour icons keep Figma's palette, the root `fill="none"` that keeps strokes hollow survives, and mask ids are prefixed per icon so two icons on one page cannot collide. Verified by mutation: dropping the `blackFollowsCurrentColor` svgo plugin turns the first case red.
Nothing checked that a synced icon actually draws the same as its Figma source. `parity:fetch` pulls Figma's own PNG per icon at scale 4, `parity:render` draws our component at the same size in Chromium, and `parity:compare` counts differing pixels with pixelmatch, failing above the gate. Both sides rasterize the vector directly, so no resampling enters the measurement. Only monochrome icons are gated. Figma and Chromium antialias the colour icons differently enough (worst 164 px) that no real signal survives, so those are reported and left ungated. compare.ts writes report.json, report.md and a self-contained report.html with the Figma / code / diff PNGs of each failure inlined. The canvas size, includeAA, threshold and gate were measured across all 594 mono icons; lib.ts records what each measurement was and why the value cannot move without redoing it. Current state: 594 mono, worst 2, none failing.
The parity check had no CI entry point, so a change to the SVGR or svgo config could alter how every icon rasterizes and nothing would notice. `icon-parity.yml` owns the check: it builds the bundle, fetches Figma's PNGs, renders in Chromium, compares, uploads report.* as an artifact on failure and leaves a sticky comment on the PR. Three entry points share that one job so the gate value and the report can never drift apart: - pull_request, on the paths that can change how an icon draws - workflow_call, from the Figma sync - workflow_dispatch, to exercise the check on demand The sync workflow cannot rely on the pull_request trigger instead: it opens and pushes its PR with GITHUB_TOKEN and GitHub raises no workflow events for those. It therefore calls the reusable workflow and passes the PR number, which required exposing `has_changes` and `pr_number` as job outputs. Slack notification moves to its own job so a parity failure reaches it too. A dispatch from a branch other than main no longer closes the open sync PR — it compared Figma against that branch, so "no changes" says nothing about main. That run now reports parity onto the open PR instead. Fork PRs are skipped: without FIGMA_TOKEN there is no baseline to compare against.

- an artifact link means download-and-unzip before anyone sees a diff; one HTML object on the bucket website opens straight from the PR comment - comment now posts on pass too, with a counts table read from report.json rather than a re-grepped markdown report — so report.md is gone - S3 upload needs OIDC `id-token`, which a called workflow cannot exceed, so the sync-icons caller has to request it as well

- `Create Pull Request` had lost its step `id`, so the `pr_number` job output silently evaluated to empty and the parity report never reached the sync PR - emit `number` on the changed-PR paths too, not just the no-changes path - temporarily pin `parity:compare` to three icons so a green run still renders Figma / code / diff images, confirming the S3 report works
- the report key now carries `run_id`: a branch-only key let a second run overwrite the page an earlier PR comment still links to, so that comment quietly started showing a different run's result - drop the two sentences under the table — "실패한 아이콘마다 …" is false on a green run, and the gate rationale belongs in lib.ts, not in every comment - stop extracting the outputs those sentences used; plumbing nothing reads is worse than no plumbing - comment as the same bot as the visual-regression one, which lands on the same PR; the default token stays reserved for machine work - restore the full compare now that S3 is confirmed to serve the images Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

A green run drew an empty table, and the comment linked to it anyway, so "열기 ↗︎" promised a diff that was not there. - compare.ts records `rendered`, the row count the page will draw - the workflow assumes the role and uploads only when that is non-zero, so a passing run skips both; the comment cell falls back to "—" - the condition is "has rows", not "failed", so it still holds once the page also carries the icons a sync changed Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A green sync PR left a reviewer with nothing to look at, even though the icons in it had just been regenerated from Figma. - `--show=A,B` adds rows to the page without narrowing what gets compared; `--only` cannot do this job, since it drops every other icon out of the gate - the sync workflow passes the icons it created or updated, so the report opens with them next to Figma; deleted ones are left out, having no component - failures lead the table and the page is capped at 60 rows, so a regeneration that marks all 814 icons changed cannot bury a failure or produce a page of several megabytes - rows without FAIL say why they are there, and empty entries in the list are dropped so the workflow can stitch it from four step outputs Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Inline comments:
In @.github/workflows/icon-parity.yml:
- Line 5: Update the reference in the icon-parity workflow comment to point to
the existing calibration rationale in the comments of parity/lib.ts, rather than
the nonexistent CALIBRATION.md path; do not add a new document.
- Line 117: Remove direct GitHub context interpolation from shell scripts by
passing values through step-level env variables: in
.github/workflows/icon-parity.yml lines 117 and 78, pass the branch reference as
BRANCH_REF and changed icons as CHANGED_ICONS, then reference them as shell
variables; in .github/workflows/sync-figma-icons.yml line 288, pass the ref as
REF_NAME and compare the quoted shell variable to main. Update all three sites
to preserve current behavior safely.
In `@scripts/icon-extractor/src/parity/compare.ts`:
- Line 29: Validate the threshold parsed in the compare flow before using it for
diff comparisons, and reject non-numeric or otherwise invalid input instead of
allowing NaN to disable the gate. Preserve DIFF_GATE as the fallback when
--threshold is omitted, while ensuring failures exit nonzero and reports never
display an invalid threshold.
In `@scripts/icon-extractor/src/parity/fetch-baseline.ts`:
- Around line 104-108: Update the fetch-baseline flow around the per-icon URL
handling so any null or missing images[icon.id] render result makes the overall
command fail with a nonzero exit status, rather than only warning and omitting
the icon. Preserve successful URL insertion for rendered icons and ensure
failures cannot silently shrink the baseline comparison set.

…gaps
CodeRabbit 리뷰 4건 반영.
- `${{ }}`는 bash가 파싱하기 전에 러너가 수행하는 텍스트 치환이라 큰따옴표 안에서도
`$(...)`가 실행된다. 브랜치명·아이콘 목록·ref 이름을 전부 스텝 `env`로 넘겼다.
특히 S3 업로드 스텝은 AWS 세션을 들고 있어 노출 대상이 자격증명이었다.
- `--threshold`에 숫자가 아닌 값이 오면 `NaN`이 되고 `diffPixels > NaN`은 항상 false라
게이트가 말없이 꺼졌다. 검증을 넣어 거부한다.
- Figma 렌더 실패를 경고로 흘리면 그 아이콘의 PNG가 baseline에 안 생기고,
compare가 baseline을 기준으로 검사 대상을 정하므로 게이트에서 조용히 빠졌다.
- 워크플로우 주석이 없는 CALIBRATION.md를 가리키고 있어 실제 근거가 있는 lib.ts로 바꿨다.

아이콘은 Figma에서 자동으로 동기화되는데, 동기화된 컴포넌트가 Figma 원본과 같게 그려지는지 확인하는 장치가 없었습니다.
무엇이 들어가나
단위 테스트 — 변환기에서 렌더링을 좌우하는 지점 여섯 군데를 고정. mono는 소비자 색을 따를 것, 컬러는 Figma 팔레트를 지킬 것, 획을 비워 두는 루트
fill="none"이 살아남을 것, mask id에 아이콘별 prefix가 붙어 한 페이지에 두 아이콘이 있어도 충돌하지 않을 것.시각 정합 검사(visual parity check) — Figma images API로 아이콘 PNG를 scale 4로 받고, 같은 크기로 우리 컴포넌트를 Chromium에 그린 뒤, pixelmatch로 다른 픽셀을 셉니다.
