[Claude #1] Stage 1 — Problem Review Round #1
Root Cause (verified)
Current state of "frame preview" artifacts (verified by file listing 2026-05-18):
data/figma_previews/{NN}.pngindex.htmlfor 1171281198 (Apr 30), 1171281210 (Apr 30) → stalefigma_to_html_agent/blocks/{frame_id}/preview.pngdriver.save_screenshotof full slide<run_dir>/phase_z2/preview.png(src/phase_z2_pipeline.py:2202)frame_partial source HTML coverage gap: only 20 / 33
figma_to_html_agent/blocks/{frame_id}/index.htmlexist (rest = catalog gap — IMP-04 soft dep).Frontend (
/frame-preview/{n}middleware,Front/vite.config.ts:444) servesdata/figma_previews/{NN}.pngonly — explicit comment line 443 says "frame_id ↔ frame_number 매핑 없음 일단 figma_previews 만 사용". Verification: mapping does exist indata/figma_previews/index.json(frame_number → frame_id). The blocker is not path-indexing but absence of a consistent rendered preview generator.Salvage anchor:
capture_slide_screenshot(src/slide_measurer.py:299) returns base64; the file-write pattern lives inphase_z2_pipeline.py:2202(driver.save_screenshot). Both are full-slide (1280×720). Per-frame rendering needs either aslide-basewrap or a frame-natural viewport.Scope-Lock Draft
In scope (IMP-13 only):
scripts/generate_frame_previews.py— idempotent, build-time only.figma_to_html_agent/blocks/{frame_id}/index.html(20 frames today; auto-expands as IMP-04 lands).capture_slide_screenshot, no AI calls, no Jinja2 prompt-mode regen).figma_to_html_agent/blocks/{frame_id}/preview.png(idempotent overwrite of auto-rendered files only).figma_to_html_agent/blocks/_preview_manifest.jsonper frame:{frame_id, source: "rendered"|"manual", html_sha256, generated_at, viewport_px}.

/frame-previewto actually serve rendered preview by frame_id (UI ticket — needsindex.jsonmapping work; would change frontend behavior).data/figma_previews/— it remains the Figma-design source.templates/phase_z2/frames/*.htmlhand-built partials (different identifier system, name not frame_id).Guardrails / Validation

slide-basewrap, OR at frame-natural bbox fromanalysis.md? Frames are sub-slide components; a full-slide wrap may distort comparison value (frame would appear small inside whitespace). Frame-natural bbox is more "preview-like" but needs reliable bbox extraction.index.html). Rendering now produces a 20-frame partial coverage; rendering after IMP-04 lands gives 32. Is it efficient to defer IMP-13 until IMP-04 lands so the first full-coverage pass happens once?preview.pngexists but no manifest entry (current 4 stale Apr 20 batch), default = treat as "manual" and preserve, OR default = re-render (since they predateindex.htmlfor 2 of 4 frames and are stale)? My recommendation: re-render with a one-time--force-recaptureflag, then mark themrenderedin manifest./frame-previewto preferfigma_to_html_agent/blocks/{frame_id}/preview.pngwhen manifest indicates rendered, falling back todata/figma_previews/{NN}.pngviaindex.jsonmapping? Or leave that to a separate UI ticket? My read: leave to separate UI ticket — IMP-13 is backend-only; otherwise scope creep.Recommendation
Given priority=low + soft dep, proceed with scope above if IMP-04 is not blocking, OR defer until IMP-04 lands. Either is defensible. Codex to decide.

[Codex #2] Stage 2: specification-based plan verification Round #1
Decision: NO. The plan covers the named issue axes, provides per-axis files/tests/rollback, includes side effects, and has an
IMPLEMENTATION_UNITSblock whose units are each within the size guardrail. However, the artifact-trace contract is internally inconsistent and needs a Stage 2 plan correction before implementation.Blocking finding:
missing_index_htmlandorphan_preview_no_index_htmlas if they can both be top-level exclusive outcomes, but the current catalog has 13 directories withoutindex.html, and1171281192is one of those 13 while also havingpreview.png. The plan states "20 rendered + 13 listed missing + 1 orphan" and proposes coverage fields withtotal_frames: 33,with_index_html: 20,missing_index_html: 13, andorphan_preview: 1. If outcomes are exclusive, that sums to 34 frame outcomes. Iforphan_previewis a subcount of missing-index frames, the schema/report must say that explicitly. This affects the issue body's "preview artifact trace" guardrail and the "all catalog frames" coverage report, so partial/inconsistent coverage = NO.What is otherwise verified:
scripts/generate_frame_previews.pyandfigma_to_html_agent/blocks/_preview_manifest.json, with tests intests/test_generate_frame_previews.py./frame-previewstill servesdata/figma_previews,data/figma_previews/index.jsonparse failure remains out of scope, chromedriver absence is handled as an environment dependency.IMPLEMENTATION_UNITSexists: u1=50 lines/1 file, u2=40 lines/1 file, u3=45 lines/1 file, u4=35 lines/1 file, u5=50 lines/1 file. No unit exceeds 50 lines or 3 files.Required plan fix:
missing_index_htmlexcludes orphan previews, so the current expected counts arewith_index_html: 20,missing_index_html: 12,orphan_preview_no_index_html: 1,total_frames: 33. If the plan wantsmissing_index_html: 13, thenorphan_previewmust be documented as a nested/subcount and the stdout/schema examples must avoid summing it as an exclusive status.=== EVIDENCE ===

.slideelement / frame contract, but the per-file plan then requires hardcoded constantsSLIDE_WIDTH=1280,SLIDE_HEIGHT=720,WINDOW_HEIGHT=920, plustest_window_size_matches_slide_contractasserting those constants. That is not "viewport choice comes from frame contract / catalog, not magic px." The Stage 2 plan should require dynamic measurement from the rendered.slideelement, settings/catalog-derived values, or another explicit frame contract source. Tests should verify that dynamic contract, not hardcoded pixel constants.PIL.Image.open().size == (1280, 720)is unsafe for the current catalog. Not every existing block HTML declares a fixed 1280x720.slide; for examplefigma_to_html_agent/blocks/1171281172/index.htmldeclares.slide { width: 1280px; ... }without fixed height and has a frame comment1579x981 pxwithzoom: 0.81064, so a frame-natural element capture is not necessarily 720px high. A fixed 720 expectation risks reintroducing silent crop/shrink or testing the wrong contract.Required plan fix:
.slideat its actual rendered element bounds and records the resulting dimensions in the manifest, or explicitly sources viewport dimensions from a real frame contract/catalog/settings path. Remove tests that assertSLIDE_HEIGHT=720as a universal contract. A smoke test may assert the PNG dimensions equal the measured.sliderectangle for the chosen fixture instead of asserting(1280, 720).What is otherwise verified:

Axis 2 — coverage / manifest schema
Before: no programmatic coverage of frame preview state.
After:
_preview_manifest.jsonschema:orphan_preview_no_index_htmlis a strict subset of frames that havepreview.pngbut noindex.html(would be 0 after IMP-04 fully resolves; current = 0 since the 4 hand-placed previews all haveindex.html). It is reported separately, but its count does NOT double-count againstmissing_index_html.

Before: no mechanism — old previews stayed stale forever.
After: per-frame skip when
(current_index_html_sha256 == manifest.frames[id].index_html_sha256) AND preview.png exists AND preview_png_sha256 matches. Otherwise re-render. mtime is NOT used (avoid git-clone mtime issues).Axis 5 — coverage report (stdout)

STAGE 2 SELF-CHECK vs REWIND FAILURE
SLIDE_WIDTH/SLIDE_HEIGHT/WINDOW_HEIGHTconstants in plan or tests. All slide-size data flows fromgetBoundingClientRect()at render time. Tests assertPNG.size == measured_slide_size(variable), never literals.(1280, 720). The size invariant under test isImage.open(preview.png).size == read_slide_natural_size(driver, file_url)— true for both width-and-height-fixed slides (e.g., explicit1280×720) and width-only-fixed slides (e.g.,1171281172which renders at width 1280, natural height derived from.innerzoom-scaled content).2400×1600is a Selenium scratch area; if any frame's.slideexceeds it, code resizes up. It is not asserted as the slide dimension anywhere.[Codex #3] Stage 2 Plan Verification Round #1 (post-rewind)
Decision: NO.
The previous hardcoded viewport blocker is fixed in the new plan: A7/u2/u4 now source slide dimensions from runtime
.slide.getBoundingClientRect(), avoidSLIDE_WIDTH/SLIDE_HEIGHTcontract constants, and test PNG size against the measured element size rather than(1280, 720). The implementation units block exists and every unit is within the stated size guardrail: u1 50 lines/3 files, u2 45 lines/2 files, u3 35 lines/2 files, u4 50 lines/2 files, u5 45 lines/2 files, u6 50 lines/2 files, u7 15 lines/1 file.Blocking finding:

Current verified counts aretotal_frames=33,with_index_html=20,missing_index_html=13,preview_png=4, andorphan_preview_no_index_html=1. The plan's own schema/example and stdout report may be examples, but the prose explicitly asserts the wrong current orphan state.1171281192cannot align with anindex.htmlmtime because thatindex.htmlis missing. This matters because rollback/overwrite behavior for an orphan preview is part of the preview artifact trace and failure-loud coverage axis.Required plan fix:
orphan_preview_no_index_html=1is documented as a subset ofmissing_index_html, not as zero.1171281192/preview.pngexplicitly: preserve/report orphan, do not render it until IMP-04 suppliesindex.html, and do not count it as a rendered or skipped-with-index preview.with_index_html + missing_index_html == total_framesand avoid double-counting orphan previews against total coverage.What is otherwise verified:

[Claude #2] Stage 2 Plan Round #2 (post-rewind)

=== CURRENT-STATE FACTS (re-verified on commit

orphan_preview_no_index_html = 0. That was wrong. Verified true value = 1. The script must therefore report orphans as a first-class manifest category, not assume "all preview.png have a sibling index.html". Renderable previews on first run = 3 of 4 (1171281198, 1171281208, 1171281210). 1171281192 will be listed as ORPHAN and skipped.=== PER-AXIS PLAN ===

Decision: PASS
I independently reran the targeted Stage 4 verification and diff/scope checks. The implementation is isolated to the two intended new files, the smoke test is green, and the catalog discovery evidence matches the Stage 2 contract.
One prior factual detail is corrected: PowerShell line counting reports

결과보고서 — IMP-13 A-3 frame preview 일관성
1. 왜 필요했나
Phase Z catalog frame이 늘어나면서 각 frame의
preview.png를 일관되게 생성하고 추적할 build-time path가 필요했다. Phase R' reference path나 runtime pipeline을 건드리지 않고, frame partial preview artifact를 안정적으로 만들 수 있어야 했다.2. 보완하려 한 기능
capture_slide_screenshot패턴을 salvage하여 catalog frame마다 preview를 생성하는 build-time script와 manifest trace를 추가하려 했다.3. 실제 변경 사항
scripts/generate_frame_previews.py를 추가했다.figma_to_html_agent/blocks/*/index.html을 discover하고, render 가능한 frame을 headless screenshot으로 preview 생성할 수 있게 했다._preview_manifest.jsonschema v1을 두어schema,generated_at,blocks_dir,summary,frames,sha256,mtime,viewport,status를 기록하게 했다.tests/test_generate_frame_previews.py를 추가해 discovery, dry-run, idempotency, manifest schema를 검증했다.4. 검증 결과
7d5639a feat(IMP-13): A-3 — build-time frame preview generator (capture_slide_screenshot salvage).scripts/generate_frame_previews.py,tests/test_generate_frame_previews.py두 개뿐이다.python -m pytest tests/test_generate_frame_previews.py -q= 5 passed.src/slide_measurer.py,phase_z2_pipeline.py, frontend Vite path에는 tracked diff 없음.5. 남긴 것 / 넘긴 것
실제 전체 preview asset 생성/갱신은 운영 실행 영역으로 남겨두었다. #13은 build-time preview generator와 manifest trace path를 추가한 것으로 close했다.
결과보고서 v2 — 디자인 프레임 미리보기 이미지 자동 생성
한 줄 요약
등록된 디자인 프레임들의 미리보기 이미지를 일관된 방식으로 생성하고, 생성 상태를 manifest로 기록하는 도구를 추가했다.
왜 필요했나
디자인 프레임이 늘어나면 사용자가 어떤 프레임인지 눈으로 확인할 수 있는 preview가 중요하다. preview가 수동으로 관리되면 누락되거나 오래된 이미지가 남기 쉽다.
프레임 catalog를 확장하려면 미리보기 이미지도 함께 자동화되어야 한다.
무엇을 보완했나
프레임 HTML을 찾아 headless browser로 미리보기 이미지를 생성하는 script를 추가했다. 또한 어떤 프레임이 렌더 가능했고, 어떤 프레임은 index.html이 없었고, 어떤 것은 orphan인지 manifest로 기록하게 했다.
사용자가 얻는 효과
프레임 선택/검토 시 시각적 확인이 쉬워진다. 새 프레임을 추가했을 때 preview 누락 여부도 관리하기 쉬워진다.
안전장치와 검증
runtime pipeline은 건드리지 않았다. build-time 도구로 분리했고, dry-run과 manifest schema를 테스트했다.
남은 한계 / 후속 작업
실제 전체 preview asset을 언제 생성하고 갱신할지는 운영 절차로 남아 있다. #13은 생성 도구와 기록 형식을 마련한 작업이다.
