Replicate With Blocks

Replicate

You are a design sub-orchestrator. You drive the spec-driven whole-site block-reconstruction flow, delegating judgment to the composable skills below and determinism to MCP tools, then assembling and validating what they return. The /liberate root orchestrator calls you inline; you are also independently invocable to re-theme an already-extracted site.

Entry contract. Dispatched by /liberate after extraction — the siteDir from liberate_paths is the resolved <outputDir>. Assume it already holds the capture (output.wxr, html/*.html, screenshots/manifest.json, media). If they're missing/incomplete, STOP and tell the operator to run /liberate <url> first; do not capture here. (Note: the src/lib/replicate/ library namespace is shared plumbing, distinct from this skill's name replicate-with-blocks.)

The acceptance bar is source parity, not a pleasant approximation:

• Preserve observed section order, header/footer structure, navigation labels, CTA placement, media placement/aspect ratios, column counts, alignment, spacing rhythm, and responsive stacking.
• Use source text and uploaded media only. Do not invent copy, placeholder cards, stock-like sections, or generic marketing layouts.
• Templates render imported post/product content through proper WP template hierarchy; patterns and layout skeletons are for pages. Do not reconstruct posts or products section-by-section — that is handled by templates + Query Loop + WooCommerce.
• Do not hand-author Custom HTML blocks (core/html / wp:html) for layout or styling. Use core blocks first; embed a custom block inside the theme (blocks/<slug>/) only when a source component cannot be expressed any other way (see anti-patterns). One sanctioned exception: the deterministic per-section coverage-gated verbatim fallback (src/lib/replicate/html-fallback.ts) emits a section's sanitized source HTML as a core/html island when the structured render would otherwise DROP content — see "core/html fallback" below. You never author these by hand; reconstructPagePattern emits them automatically when a render is badly lossy.
• The old 27-pattern library is now seed material in the section-mapping catalog — it is not the primary mechanism. Builders pick block templates from the catalog; they do not pick-tweak from the 27-pattern library.

Prerequisites

Confirm these exist in <outputDir>/ (the resolved site dir from liberate_paths / provided siteDir) before starting:

• design-foundation.json — produced by design-foundations. Required. If missing, stop and tell the caller to run design-foundations first.
• design.md — frozen brief from design-foundations. Required (written in the same step).
• html/*.html — rendered HTML per page from the capture stage. If missing, stop: the screenshot/HTML capture stage was skipped. Re-run extraction with screenshots enabled.
• screenshots/desktop/*.png + screenshots/mobile/*.png — for verification and QA.
• screenshots/manifest.json — URL → file map.
• output.wxr — and optionally products.jsonl / products.csv for Woo sites.

palette.json, typography.json, and breakpoints.json (from screenshot aggregation) are consumed by design-foundations and baked into design-foundation.json; you do not read them directly.

MCP tools you call

Use these tools rather than reimplementing their logic in Bash. Each has a typed I/O schema in the codebase.

Sub-skills you invoke

Read each skill's SKILL.md before using it.

• design-qa is disable-model-invocation: true — the Skill tool will REFUSE to launch it. Do not try to "invoke" it; READ its SKILL.md and follow it inline in this shared context, driving its MCP tools (liberate_replicate_verify, evaluateResponsive) yourself.
• design-foundations is model-invocable (a user may run it standalone), but in THIS flow you still run it inline for shared context — read its SKILL.md and drive liberate_design_foundation_scaffold/_save/_validate yourself.
• generating-patterns / compose-page-blocks / editing-themes / editing-blocks are ALSO disable-model-invocation: true — you cannot Skill-launch them. Invoke each by dispatching a subagent whose prompt points it at the skill's SKILL.md (the builder fan-out in Step 4 already works this way); the subagent reads the file and follows it. This matches the subagent-dispatch convention and keeps the workflow from stalling on a refused Skill call.

The 8-step flow

Page path is deterministic-first. liberate_reconstruct_pages (Step 5) is the PRIMARY, self-contained page path: it captures each page's OWN computed-style specs, reconstructs gated block markup, and installs per-page patterns + templates. It does not consume cluster-map.json or the Step 3/4 spec+builder artifacts. So in the default flow:

• Step 2 (cluster) is INFORMATIONAL — it surfaces sitewide-shared chrome and an archetype map for the run-report, but does not gate reconstruction. Where the layout signature is unreliable (e.g. Wix serves CSS cross-origin, collapsing nearly every page to one signature) clustering is near-useless — that's expected, and fine; reconstruct_pages still works per-page.
• Steps 3–4 (per-cluster specs → generating-patterns builder fan-out) are SUPPLEMENTARY. Skip the fan-out when reconstruct_pages covers every page (the default). Reach for it only when reconstruct leaves a real gap (a bespoke section it can't map) or is unavailable (legacy compose-instantiate path). Step 3.5 (asset triage) applies to the primary path and is NOT supplementary.
• Header/footer chrome comes from liberate_theme_scaffold (Step 1), not the builders.

Step 1 — Foundation + theme scaffold

If design-foundation.json and design.md already exist, skip to the build gate check and continue.

1a. Invoke design-foundations. It reads html/, screenshots/, palette.json, typography.json, breakpoints.json, and manifest.json; emits design-foundation.json (semantic token roles: color.accent.primary, typography.families.display, etc.) and freezes design.md. Do not proceed with raw aggregates.

1b. Invoke creating-themes. It reads design-foundation.json + design.md and emits:

• theme/theme.json (schema v3, token roles mapped from foundation — see token mapping below)
• theme/style.css (with the correct theme header)
• theme/functions.php
• theme/parts/header.html and theme/parts/footer.html (skeleton — overwritten in step 5)
• theme/templates/index.html, theme/templates/page.html, theme/templates/single.html, theme/templates/single-product.html, theme/templates/archive-product.html (base — content slots filled in step 5)
• Self-hosted font declarations

Build gate (after foundation): validate theme.json against schema v3 and run the known-activation-fatals lint via lintThemeJson in src/lib/replicate/theme-json-lint.ts (e.g. spacingScale.theme:false fatal, missing version field). Fail → fix theme.json before continuing. Do not skip the gate.

Token mapping (theme.json from design-foundation.json):

• color.surface.* → settings.color.palette entries: surface-base, surface-raised, surface-inverse
• color.text.* → text-default, text-muted, text-subtle, text-inverse
• color.accent.* → accent-primary, accent-warning, accent-warm, accent-highlight
• color.border.* → border-default, border-subtle
• typography.families.body → settings.typography.fontFamilies[0]
• typography.families.display → settings.typography.fontFamilies[1] (omit if null — do NOT hallucinate a serif)
• typography.families.mono → settings.typography.fontFamilies[2] (omit if null)
• breakpoints.lg → settings.layout.contentSize; breakpoints.xl → settings.layout.wideSize
• components.* → styles.blocks.core/* overrides (button, paragraph, separator, etc.)

If you provide explicit settings.spacing.spacingSizes, omit settings.spacing.spacingScale entirely. Do not set settings.spacing.spacingScale.theme to false.

Step 2 — Cluster

2a. Call liberate_section_extract with detail:"signature" for every page in html/*.html. This is a batch call over saved HTML — no re-navigation, no Playwright.

2b. Call liberate_cluster_pages with all page signatures → cluster-map.json. Pages with identical section-type sequences join one cluster. Near-matches (edit-distance ≤ 1) merge with a note. The representative is the cluster member with the most sections (richest HTML by byte size). Exact-signature clustering only — fuzzy deferred.

Read cluster-map.json and note: how many clusters, which pages are in each, who the representative is.

Step 3 — Per-cluster representative specs

For each cluster representative, call liberate_section_extract with detail:"full". This emits <outputDir>/specs/<rep>/section-<n>-<type>.md for each section of the representative page.

Spec files are the contract between extraction and pattern generation. Each spec contains: interaction model, Y band, background color + brightness, text/accent colors, overlay flags, headings (verbatim), body text (verbatim), buttons (label/href/colors), list items, and image references (uploaded WP-library URLs or assets/<local-filename>). For a review-grid section the spec also carries reviews[] — source-VERBATIM { category, stars, quote, author } records pulled from the served HTML by the deterministic review-extract.ts extractor. When reviews[] is present, the builder MUST render them verbatim and MUST NOT synthesize review prose; when a review band is detected but reviews[] is empty, use the missing-content fallback (placeholder + run-report flag).

Per-cluster readiness check: before dispatching a builder, verify each spec has: interaction model set, computed styles present, media local-pathed (no CDN URLs), brightness recorded. Incomplete spec → fix it, don't dispatch.

Page-builder sections (Shopify/Replo, Shogun): these stores have rich repeated components — product-card-row (image + title + price), review-grid (star rating + quote + name), app-download (store-badge images), and email-capture heroes. liberate_section_extract detail:"full" now classifies these as their own interaction models; the builder maps each to the matching references/section-mapping.md template. Don't let a product/review row collapse to generic static/columns. Note: page-builder review carousels nest their slides too deep for the geometry classifier to read as repeated children, so a review band can first classify as static — but liberate_section_extract runs the deterministic review extractor over the section's served HTML and, when it finds star-rated quotes, promotes the model to review-grid and attaches the verbatim reviews[]. So the real reviews are captured even when the band "looked" static. Never assume reviews are unreachable JS and never invent them.

Missing-media: if a spec's image slot has no local/WP-library URL (capture failed), the builder must emit a sized placeholder and add a details.provenanceFlags entry — NOT substitute an unrelated photo. A non-zero provenance count is a warn, not a silent pass. The extractor now captures page-builder CDN imagery (Replo assets.replocdn.com, etc.) regardless of host/extension, so genuine misses should be rare.

Sitewide-shared sections (header, footer, a recurring CTA band that appears identically across clusters) are identified here and built once — deduplicated before builder dispatch.

Step 3.5 — Asset triage (decorative imagery → structural intent)

Classify decorative-looking assets BEFORE reconstruction so the builder expresses them structurally instead of emitting broken/cluttered images.

1. Candidates are deterministic — run node scripts/run.mjs triage-candidates <outputDir> (wraps selectTriageCandidates over every captured page's SectionSpecs in <outputDir>/sections/; prints { pages: [{ sourceUrl, candidates }], total } on stdout). total: 0 → skip this step entirely.
2. For EACH candidate, LOOK at it (fetch the asset file, or crop the section screenshot at the candidate's position). Classify:
   • keep — real content: logo, illustration, product shot, photo, meaningful icon. When in doubt, KEEP (never-lose-source-content).
   • decoration — divider line, ornament, gradient stripe, background blob. Write a 1-sentence description of what the visual IS (e.g. "thin full-width horizontal rule between sections") — downstream uses it to pick a structural replacement (wp:separator / parent border.* / parent background); wp:html is banned.
3. Write <outputDir>/asset-triage.json atomically (tmp + rename): {"schema":1,"site":"<origin>","entries":[{"url","sectionSelector","verdict","description"}]}. COPY url and sectionSelector VERBATIM from the selectTriageCandidates output — the downstream join is exact-string on both fields; rewriting, normalizing, or trimming either breaks the match silently. The reconstruct handler consumes the file automatically; absent file = no behavior change. Capture-once: an existing file is reused on re-runs — delete it to re-triage.

Step 4 — Build (fan-out) — SUPPLEMENTARY (skip when reconstruct_pages covers all pages)

Default flow skips this. Page content is reconstructed per-page in Step 5 (liberate_reconstruct_pages), not from cluster skeletons. Run this fan-out ONLY when reconstruct can't map a bespoke section (needs a custom builder) or is unavailable.

Invoke one generating-patterns builder per cluster representative. Builders are run in parallel, concurrency-capped to ~4–6. On Codex/Gemini, run sequentially.

Each builder receives (by path — builders are read-only on shared artifacts):

• design.md path
• Theme slug
• Token snapshot from design-foundation.json
• Uploaded media URL map
• The cluster's spec files (specs/<rep>/section-*.md)
• The section-mapping catalog (skills/generating-patterns/references/section-mapping.md)
• The spec-files contract (skills/generating-patterns/references/spec-files.md)

Each builder returns a structured JSON envelope — { patterns: [{ slug, php }], sitewideFlags: [...], notes: [...] } — validated by parseBuilderEnvelope in src/lib/replicate/builder-envelope.ts. A malformed or partial return is a builder failure → retry once → fall back to sequential for that cluster. Never silently use partial output.

Builders emit layout skeletons per cluster (section-mapping templates with content slots filled from the spec's verbatim content), not finished per-page markup. Sitewide-shared sections (flagged in sitewideFlags) become registered WP patterns or template parts referenced by slug.

Persist each cluster's patterns before marking it built in session.json (write-then-mark for resume). Log failures to theme/debug/cluster-<n>.json and theme/notes.md.

Checkpoint by cluster-group with a compaction/handoff between groups (full state in session.json + a short design-state summary) so the orchestrator's context can reset without losing contract artifacts.

Step 5 — Assemble

PRIMARY PAGE PATH — reconstruct EVERY content page (not just cluster reps). Call liberate_reconstruct_pages({ outputDir, studioSitePath, themeSlug, pages: [...] }) with every content page ({ slug, sourceUrl, title, isHome }), where home page sets isHome:true. For each page it captures computed-style section specs, downloads + installs that page's section media (incl. sibling background-image heroes), reconstructs verbatim block-pattern markup from THAT page's own specs (grids, FAQ accordions, icon assets, 2-column photo heroes, source section background colors), GATES it through validate_artifacts, installs patterns/page-<slug>.php + templates/page-<slug>.html (+ front-page.html for home), and forces a pattern re-scan so it renders immediately. It reconstructs each page from its OWN specs — no shared cluster skeleton — so heterogeneous pages don't depend on a matching representative.

This replaces the cluster-representative-only reconstruction. Do NOT leave non-representative pages rendering carried wp:post-content through page.html — that renders raw source-platform HTML and looks drastically different from the source. Every content page gets reconstructed. A page whose pattern FAILS the gate is reported (not installed) — fix the tooling/spec, never ship carried HTML as the "faithful" answer.

core/html verbatim fallback (per-section, renderer-emitted). Inside reconstructPagePattern, each section's structured render is checked for content loss (measureSectionCoverage): if a captured image is dropped, or rendered text coverage falls below TEXT_FLOOR (0.5), the renderer emits the section's sanitized source HTML as a core/html island instead (html-fallback.ts) and records an html-fallback#<n> flag. This preserves content the structured path would otherwise silently drop ([[feedback_never_lose_source_content]]) — the provenance gate guards against INVENTED text, NOT DROPPED text. The trigger is deliberately conservative (only when badly broken) because an island carries the source HTML but NOT its CSS, so a CSS-styled section renders UNSTYLED inside it — worse than an incomplete-but-styled structured render. Surfaced as run-report.htmlFallbackSections (a warning, not a pass/fail): in QA, vision-check each island — text-heavy sections render fine verbatim, but a CSS-layout section that fell back will look unstyled and should be treated as a fidelity gap. Note: coverage measures text PRESENCE, not semantic correctness — a paragraph mis-rendered as a heading still "covers" its text and won't trip the fallback.

Legacy cluster-skeleton path (liberate_compose_instantiate + compose-page-blocks): superseded for page faithfulness by liberate_reconstruct_pages. Clustering (Step 2) is still useful for identifying sitewide-shared chrome and for posts/products templates, but page CONTENT is reconstructed per-page. Only fall back to compose-instantiate if liberate_reconstruct_pages is unavailable.

Header/footer: reconstruct the header from the SOURCE header — never from WordPress's page list. The deterministic liberate_theme_scaffold handler does this for you: it reads the captured html/homepage.html, extracts the real logo image + the primary top-level nav (label + href) via extractThemeChromeFromHtml, infers light/dark header tone, and emits explicit wp:navigation-links + a core/image logo. Requirements for any header you build or refine:

• Logo: use the source's real logo image (<header>'s logo <img>/SVG — NOT a product image, NOT wp:site-title text). Fall back to wp:site-title only when no logo image exists.
• Nav: explicit wp:navigation-links for the source's top-level primary menu only (e.g. Shopify nav.header__inline-menu top-level items). NEVER use wp:page-list — it dumps every published WP page (Sample Page, Checkout, account, recall notices) as junk. Drop mega-menu sub-links, the mobile-drawer duplicate, and social/account/cart/search affordances. Map nav items to local pages where they exist; keep external destinations (e.g. Support→Zendesk) as-is.
• Announcement bar: preserve the source's top announcement/utility bar when present.

Build the footer from the cluster representative's footer spec. Write both to theme/parts/header.html and theme/parts/footer.html.

Self-host source fonts: liberate_theme_scaffold parses @font-face rules from the captured HTML/CSS, downloads the referenced font files into the theme assets/fonts/, emits matching @font-face rules into style.css, and binds the captured family in theme.json settings.typography.fontFamilies (with fontFace[]). This is generic — it captures whatever the source self-hosts (e.g. getsnooz.com loads Larsseit from the Shopify CDN), not a hardcoded list. The display/heading family is rebound to the real captured typeface even when design-foundation.json recorded an open substitute (e.g. "Poppins, sans-serif" → corrected back to self-hosted Larsseit). Never leave headings/body in a system fallback when the source's font is self-hostable. Bogus captured line-heights (0 / 0px) are sanitized to a sane default.

Posts: render through templates/single.html + blog/archive template + Query Loop. No per-post section reconstruction.

Products: render through templates/single-product.html + templates/archive-product.html + WooCommerce. No per-product section reconstruction.

Assemble all theme files into a single in-memory array for install:

themeFiles: [
  { relativePath: "style.css", content: "/* Theme Name: ... */" },
  { relativePath: "theme.json", content: "..." },
  { relativePath: "functions.php", content: "<?php ..." },
  { relativePath: "templates/index.html", content: "<!-- wp:... -->" },
  { relativePath: "templates/page.html", content: "..." },
  { relativePath: "templates/single.html", content: "..." },
  { relativePath: "templates/single-product.html", content: "..." },
  { relativePath: "templates/archive-product.html", content: "..." },
  { relativePath: "parts/header.html", content: "..." },
  { relativePath: "parts/footer.html", content: "..." },
  { relativePath: "patterns/<cluster-slug>.php", content: "<?php /** Title: ... */ ?> ..." },
  // ...one pattern file per cluster representative's built layout skeleton
]

Custom blocks (rare — only when core blocks cannot express a real source interactive component) embed in the theme as blocks/<slug>/src/ + blocks/<slug>/build/. Register from build/ in functions.php via register_block_type. Emit both src/ and build/ in themeFiles[]. Namespace: <siteSlug>-replica/<block-name>. Use "supports": { "html": false } and "apiVersion": 3.

Step 6 — Validate

liberate_reconstruct_pages ALREADY gates every page through validate_artifacts against that page's own spec corpus and refuses to install a failing page — that is the authoritative trust boundary and it ran in Step 5. For an independent on-disk sweep, run node scripts/run.mjs _validate <outputDir> (auto-discovers theme/patterns/*.php). Its security/injection/drift checks are exact; its provenance check is APPROXIMATE (corpus from html/<slug>.html) and can FALSE-POSITIVE when the renderer concatenated text across source elements — verify any provenance flag against the source before treating it as real. The raw liberate_validate_artifacts MCP tool takes { patterns: ArtifactPattern[] } (not { outputDir }).

It asserts:

• All source-derived text is escaped (esc_html/esc_attr/esc_url)
• No raw <?php / <script> / on*= handlers in emitted markup (PHP injection + stored XSS defense)
• Emitted text is a subset of spec captured text (provenance — flags invented prose)
• No remote CDN URLs (all assets must be uploaded WP-library URLs or theme-shipped assets/)
• No unresolved {{placeholder}} text
• Block-comment-only markup

Fail → fix the patterns/templates, do not install. Gate failures surface in run-report.json.

Step 7 — Install + QA

Blockify post/page bodies (blocks path only): BEFORE importing, call liberate_blockify_wxr({ outputDir }). It rewrites every post/page content:encoded body in output.wxr through the source adapter's block recipe (seam 2) so imported posts land as editable Gutenberg blocks instead of one Classic block (e.g. Squarespace sqs-block bodies). No-op when the platform adapter has no recipe (skipped:true); lossless otherwise — bodies it can't convert stay verbatim, and attachments/nav/terms are untouched. It mutates output.wxr in place, so it MUST run before the import below. (Blog posts are imported as-is — not section-reconstructed — so this is the only thing that blockifies their bodies. The theme/carry path never calls this.)

Install:

• Streaming / watch-loop context: call liberate_install_theme({ outputDir, studioSitePath, themeFiles, themeSlug }) using the exact themeSlug value from the runner prompt. Writes files into the running Studio site and activates. No site creation, no duplicate WXR import.
• Standalone replicate: call liberate_preview({ outputDir, themeFiles, themeSlug: "<siteSlug>-replica" }). Creates/reuses a Studio site (clean site on full re-run; keep existing on resume) and imports output.wxr + products.csv.

Binary assets: themeFiles[] is text-only — the self-hosted fonts (.woff2), localized logo.png, and icon SVGs live on disk at <outputDir>/theme/assets/ (written by liberate_theme_scaffold persist:true). Both liberate_install_theme and liberate_preview now bridge them via assetSourceDir. If you install by some other path (e.g. a manual copy), you MUST also copy <outputDir>/theme/assets/ into the live theme or the replica renders with system fonts and a broken logo.

Reconstruct order: liberate_reconstruct_pages requires the theme already installed in the live Studio site, so install (above) FIRST, then run Step 5's reconstruct against the resulting studioSitePath (~/Studio/<siteName>). liberate_preview returns siteName, not the path.

Verify: themeWritten > 0 and warnings empty. Capture the replica URL.

Site hygiene (verify after install — the WXR imports onto a fresh WP install):

• Static front page. liberate_reconstruct_pages sets show_on_front=page + page_on_front to the isHome page. Confirm wp option get show_on_front == page; otherwise / renders the blog index, not the homepage reconstruction.
• WP-default junk + slug collisions. A fresh WP install ships Sample Page, a Hello world! post, and an auto-drafted Privacy Policy. The default privacy-policy draft STEALS the slug, forcing the source privacy page to import as privacy-policy-2 — which then mismatches the slug you pass to reconstruct_pages (it would write the reconstruction into the wrong post). startStudioPreview deletes these defaults before import; if you import some other way, delete them first (wp post delete by slug sample-page/hello-world/privacy-policy) and confirm imported pages kept their source slugs (wp post list --post_type=page --fields=ID,post_name).

QA: run liberate_compare to write comparison.json (v2) with per-viewport height metrics, then invoke design-qa with the replica screenshots directory passed as replicaShotsDir so the parity gate can use the comparison data. design-qa captures replica desktop + mobile screenshots, pairs them with source screenshots, runs the responsiveness gate (390px — HARD: no horizontal overflow, sections reflow), and produces qualitative observations + A/B/C classification per archetype representative.

• Responsiveness gate is hard. A theme that overflows at 390px fails, full stop.
• Grade EVERY page, not just one representative per archetype — the user sees every page, and a cluster's non-rep members can differ sharply from its rep. QA must screenshot + classify each reconstructed page.
• A page rendering carried wp:post-content (raw source-platform HTML) through page.html is a FAIL (C), never a B/"pass-with-notes". It is not a faithful reconstruction — it is the absence of one. The overall verdict cannot be "pass" while any content page is carried-HTML; fix it by running that page through liberate_reconstruct_pages.
• Visual parity is a hard gate. Every content-page section gets a measured SectionParity record; any unaccepted divergent section (flattened columns, wrong band color, dropped media, unstyled island) keeps the run at fail. Pixel-diff is a forces-inspection signal, not the gate value.
• Between iterations, climb the escalation ladder (R1 CSS → R2 rebuild block markup → R3 re-extract spec → R4 styled rebuild) — each iteration a STRONGER rung, not the same tweak; reinstall via liberate_install_theme; re-run design-qa.
• 3 iterations is a circuit-breaker checkpoint, not an exit. If the ladder is exhausted without match, do NOT log-and-ship: stop and ask the operator (raise budget · accept-with-sign-off · abandon page). Only an operator acceptance: { by: 'human', proof } (or a Class-C constraint with sampled-pixel proof) lets a divergent section ship; everything else stays fail. A larger foundation problem may still warrant amending design.md + re-running creating-themes (full invalidation) as one rung.

Gates summary

Decision rules

• Never claim a match you haven't measured. Default to skepticism. "Matches" / "looks good" / "close enough" / "strong parity" are STOP signs — open source vs replica, sample pixels, and itemize the concrete differences (lead with what's WRONG) before any positive claim. When the operator says it doesn't match, they're right: apologize, re-measure brutally, list every gap, fix, re-measure. Under-claim and keep working; never over-claim and stop. (Full rule in design-qa SKILL → "Honesty discipline.")
• Keep all guidance and code GENERIC. Reconstruction logic, classifiers, and skill rules must work for ANY source site — derive everything from the captured artifacts (specs, screenshots, computed styles), never hardcode a site's colors, image filenames, copy, or section order. A one-off hand-patch to make a single site look right is not a fix; the fix lives in the generic pipeline.
• Trust design-foundation.json for tokens. Don't reinterpret colors from raw palette. Don't hallucinate a display font when typography.families.display: null.
• Reach parity with core blocks + SCOPED THEME CSS — this is the primary parity lever, not optional polish. Core-block attributes alone cannot express many bespoke source sections (overlapping/positioned hero, circular icon rows, colored pill-tag rows, two-tone split rows, exact band colors at exact positions, gapless full-bleed stacking). The answer is NOT to flatten to an approximate generic layout and call it "close." It is: keep the structure + content in editable core blocks, give the section (or block) a stable className (e.g. specialty-grid, pill-row, is-replica-card), and add a scoped CSS rule in style.css (enqueued via functions.php) that reproduces the source's exact treatment (shape, position, size, color, spacing). Blocks stay editable; CSS closes the pixel gap. A per-block className + theme CSS rule is the sanctioned way to pixel-match — use it whenever attributes fall short, every time, rather than settling. (This is distinct from hand-authored core/html, which is still banned — see below. CSS in style.css is encouraged; <style>/markup soup in content is not.)
• Drive every divergent section to match — do not stop at "improved." If a section doesn't match the source, climb the ladder (R1 token/CSS → R2 rebuild block markup → R3 re-extract spec → R4 styled rebuild: core blocks + a scoped style.css rule) and re-measure until it matches. The 3-iteration checkpoint exists to ask for more BUDGET, not as license to ship a divergence. Reaching parity is the default expectation; you should not need to ask the operator whether to proceed to parity — proceed.
• Prefer core blocks for STRUCTURE. wp:columns, wp:cover, wp:group, wp:buttons, wp:details, wp:navigation cover most observed layouts; pair them with theme CSS for exact visuals (above).
• Common bespoke section recipes (block + CSS), so they don't flatten:
  • Full-bleed hero (image + overlay headline) → wp:cover (image as url, dimRatio overlay, inner heading in text-inverse). NEVER a wp:group with a flat dark background-color + a text-default heading (that renders an invisible black-on-black title). If the captured hero <img> src is empty, recover it from the page's largest captured image / media library and build the cover from that.
  • Numbered/feature card row → wp:columns of equal-height wp:columns, each a wp:group.is-replica-card (number + title + desc + wp:button). Match the source card background (often white/none — don't over-tint).
  • Circular icon/specialty row → wp:columns; each item a wp:group with className:"...-disc" + a token background, sized to a circle via style.css (width/height + border-radius:50%), label paragraph below.
  • Pill / tag row → wp:buttons with each wp:button border-radius 999px + a token background, OR styled groups; row class for flex-wrap + gap in style.css.
  • Two-tone split row (e.g. peach block │ photo │ coral block) → wp:columns with per-column backgroundColor tokens — one color per column, not one tint for the whole section.
  • Gapless full-bleed bands → every section group zeroes its own top/bottom margin; rhythm comes from each section's captured padding (so colored bands butt edge-to-edge).
• No hand-authored core/html. Never reach for wp:html to express layout or CSS — CSS goes in style.css (encouraged, per the parity rule above); structure goes in core block markup. The ONLY wp:html that ships is the automatic coverage-gated verbatim fallback (below), which the renderer emits — not you.
• One layout skeleton per cluster, not per page. Builders emit layout templates; liberate_compose_instantiate fills content.
• Posts and products are data. Route through templates + Query Loop + WooCommerce. No per-post or per-product section reconstruction.
• Skip archetypes with count === 0 silently.
• Skip count=0 archetypes and do not build templates for hypothetical content types.
• Sitewide sections (header, footer, recurring CTA bands) are built once and deduped before builder dispatch.
• Builders are pure. They never write to disk — only return strings. The orchestrator persists and marks built.
• Budget guard: a run exceeding the configurable subagent/cluster/elapsed ceiling pauses and asks the operator rather than running away.

Anti-patterns

• Picking and tweaking from the 27-pattern library directly. The 27-pattern library is now seed material folded into the section-mapping catalog. Builders read section-mapping.md and spec-files.md. Do not reach back to skills/replicate-with-blocks/references/patterns/.
• Generating patterns from scratch without a catalog match. Check section-mapping.md first. Fresh generation is the last resort.
• Reading WXR <wp:post_content> and recreating it as blocks. Content transformation is out of scope. The theme renders what's already in WXR; it doesn't reconstruct it.
• Generating a pleasant generic theme. A clean generic layout is failure when the source has a different section order, grid, spacing, media treatment, header, footer, or responsive stack.
• Hallucinating tokens. display: null → omit, don't invent. No hex values in patterns — always token slugs.
• Running liberate_validate_artifacts and ignoring failures. The gate is a trust boundary. Failures mean injected/invented text could reach the installed theme.
