Problem and value

Current-main trigger: two things in step 3 of the fast authoring path force an agent to learn by failure. (1) "at most 12 primary nodes" offers no legitimate path above 12 — enterprise architecture diagrams legitimately need more (a current real diagram: 14 components, 15 relationships, 4 boundary regions, passes showcase 0/0 and fits all four viewports), and the hard-sounding cap pushes an agent toward deleting real components or splitting one truthful diagram. (2) There is no viewport-budget hint at authoring time; validate does not estimate page overflow, so coordinates are designed blind and overflow surfaces only after deliver + visual-check, when the spec is already frozen.

Intended outcome: the authoring agent budgets the viewBox from the start and groups >12-node topologies instead of amputating them.

Approach: extend step 3 by one sentence each — a pointer to the "Viewport height budget" section in references/authoring-contract.md (added by companion PR, referenced by section name only, so no hard dependency) and the layer-band grouping path for >12 nodes. Narrow documentation correction; no planning issue needed per CONTRIBUTING.

Stability impact

  • Impact class: documentation only (SKILL.md authoring guidance). No code, schema, or acceptance-rule changes.
  • Existing behavior preserved: the entire original step-3 text is retained; both additions are appended, nothing reworded or removed.
  • No unrelated changes: confirmed — single file, 1 line rewritten (appends only).

Tests run

  • Comparison base: main @ 1072200. Candidate: this branch (1 commit).
  • Frontmatter untouched; archify doctor passes with the modified SKILL.md in place.
  • No automated checks apply to prose.

Visual evidence

Not applicable — documentation-only change.

Generated artifacts

None.

📝 Summary

Summary

Updates archify/SKILL.md Step 3 with layout guidance for the fast authoring path. When a topology needs more than 12 primary nodes, authors should group extra nodes into horizontal layer bands of no more than 5 nodes instead of deleting components. The guidance also requires a viewBox width/height ratio from 2.0 to 4.0 and up to 4 short card items.

Compatibility impact

Documentation-only change. No code, schema, frontmatter, or acceptance-rule changes.

Validation

The author reports that archify doctor passes. The requested inspection did not complete because it used an incorrect path for references/authoring-contract.md. No browser or perceptual acceptance is verified.

Layout guidance

Layer / File(s) Summary
Step 3 layout budget
archify/SKILL.md
Step 3 permits horizontal bands of up to five nodes when a topology exceeds 12 primary nodes. It also requires a viewBox width-to-height ratio from 2.0 to 4.0 and up to four short card items.

Priority: ⬇️ Low — Defer this documentation-only guidance update because it narrowly affects authoring instructions for large topology layouts without code or acceptance-rule changes.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to 30809

The new fast-path guidance can permit overly wide diagrams and sends authors to a missing detailed-layout section, reducing the reliability of first-screen diagram authoring. Correct the ratio bound and reference before merging.

Explanation

The PR changes a packaged Skill input but does not refresh the required generated package. CONTRIBUTING.md requires ZIP freshness checks for published Skill-instruction changes, and CI compares archify.zip with a rebuild. The parent and final commits contain the same archify.zip blob, while the ZIP's archify/SKILL.md matches the parent and not the final SKILL.md. The PR reports only archify doctor; it does not provide the required npm test or ZIP-freshness result. The new “Viewport height budget” reference also names a heading that is absent from archify/references/authoring-contract.md and delivery-contract.md.

Resolution

Update the reference to an existing section or add the named section. Rebuild archify.zip from the final source with the required Node 22 builder and commit the result. Run cd archify && npm ci && npm test, run the ZIP freshness comparison, and provide final-head results or CI links in the Tests run and Generated artifacts sections. Keep the visual evidence explanation as Not applicable; screenshots are not required for this non-visual change.

1. Choose `architecture`, `workflow`, `sequence`, `dataflow`, or `lifecycle` from the question.
2. Read one matching schema in `schemas/`, `schemas/common.schema.json`, and one matching JSON example in `examples/`. Read only those files. Fresh authorship means new stable IDs, domain wording, and layout; use the example for field shape, not facts. New workflow sources use `schema_version: 2` and its readable layout contract; keep `schema_version: 1` only when preserving an existing workflow's fixed geometry. When real product identity matters, query `node bin/archify.mjs brands "<name>" --json`; read `references/brand-marks.md` only for an unknown brand with a user-provided URL.
3. Artifact first: the next tool action must write the candidate. Write the candidate before inspecting renderer internals. Do not plan exact coordinates in prose. Start with one clear main path, short side branches, sparse labels, and at most 12 primary nodes. Set `meta.quality_profile` to `"showcase"` unless the user explicitly requests a dense `standard` map. Start with automatic routes and labels. Do not add `via`, `channelX`, `channelY`, or `labelAt` before a diagnostic calls for one; apply at most one diagnosed geometry control per repair.
3. Artifact first: the next tool action must write the candidate. Write the candidate before inspecting renderer internals. Do not plan exact coordinates in prose. Start with one clear main path, short side branches, sparse labels, and at most 12 primary nodes. When a real enterprise topology genuinely needs more, group the extras into boundaries as horizontal layer bands of ≤5 nodes each instead of deleting real components. Set `meta.quality_profile` to `"showcase"` unless the user explicitly requests a dense `standard` map. Start with automatic routes and labels. Do not add `via`, `channelX`, `channelY`, or `labelAt` before a diagnostic calls for one; apply at most one diagnosed geometry control per repair. Layout budget: `validate` does not estimate page overflow; author the viewBox with width/height ratio ≥ 2.0 and ≤4 short card items so the 1440×900 first-screen pass holds — see the Viewport height budget section in `references/authoring-contract.md`.

Keep the full viewBox ratio bound.

Line 21 states only width/height ratio ≥ 2.0. The authoring contract requires a ratio between 2.0 and 4.0. Without the upper bound, this guidance permits excessively wide viewBoxes and weakens the first-screen layout contract. State the rule as 2.0 ≤ width/height ≤ 4.0.

As per path instructions, archify/** must preserve the documented first-screen layout contract.

Point to an existing viewport-budget section.

Line 21 references the “Viewport height budget” section in archify/references/authoring-contract.md. The supplied cross-file context does not contain that section. The detailed desktop viewport and overflow contract is in archify/references/delivery-contract.md. Update the pointer or add the named section so fast-path authors can reach the required guidance.

As per path instructions, archify/** requires stable authoring and delivery references.
