Problem and value

Current-main trigger: all 11 existing scenario recipes answer "which diagram type should I draw?" Mid-repair questions return nonsense:

$ archify guide "viewport overflow" --json
matchedSignals: ["architecture"]  →  recommendation: system-overview   # a diagram-type pick, useless mid-repair

During actual repair loops the questions are "why does it still overflow", "which fix order", "how do via waypoints work" — currently answerable only by reading the contract docs after already hitting the errors.

Intended outcome: guide returns the repair playbook for repair-phase queries.

Approach: add a 12th recipe layout-repair (bilingual en/zh) with signals overflow / viewport overflow / scrollheight / overlap / label overlap / edge through node / edge-through-node / crossing / via / layout repair / fix layout (+ Chinese 溢出/视口溢出/压标签/穿节点/布局修复). The recommendation text returns: repair order (schema → overlap → direction → crossings → labels), the via direction contract, the viewport height budget, and the rule of applying diagnosed supportedFixes over hand-estimated coordinates. Pure data addition — the existing scoring machinery picks it up with zero code changes; no schema, default, or acceptance-rule impact, so no planning issue needed per CONTRIBUTING.

Stability impact

  • Impact class: additive data in recipes/scenarios.mjs. No code paths changed; recommendScenario/formatScenario*/publicGuideData untouched.
  • Existing behavior preserved: all 11 recipes byte-identical; the new recipe only wins when its repair-specific signals score above existing matches (verified: 架构图 系统总览 still recommends system-overview).
  • No unrelated changes: confirmed — single file, +21 lines, one new array element.

Tests run

  • Comparison base: main @ 1072200. Candidate: this branch (1 commit).
  • archify guide "viewport overflow" --jsonlayout-repair, confidence high, matched [overflow, viewport overflow, viewport].
  • archify guide "视口溢出" --lang zh --jsonlayout-repair, confidence high.
  • Regression: archify guide "架构图 系统总览" --lang zh --jsonsystem-overview (no drift on existing queries).
  • archify doctor → "Archify is ready."
  • Module loads cleanly under Node 22 (recipe shape matches the frozen-export mapping in scenarios.mjs).

Visual evidence

Not applicable — CLI data addition; no rendering path touched.

Generated artifacts

None; scenarios.mjs is hand-authored source, not generated.

📝 Summary

Summary

Adds a bilingual layout-repair scenario recipe for diagrams with viewport overflow, edge crossings, node overlaps, or label collisions.

The recipe recommends repair order, the via direction contract, viewport height budgeting, and applying diagnosed supportedFixes.

Compatibility

This is an additive data-only change. Existing recipes, schemas, defaults, code paths, and acceptance rules remain unchanged.

Validation

Author-reported regression checks confirm that layout-repair queries select layout-repair and existing architecture queries select system-overview. These checks do not verify browser rendering or perceptual layout acceptance.

Walkthrough

Adds a bilingual layout-repair architecture recipe for diagrams that pass validation but have viewport overflow, line crossings, or label collisions. The recipe is included automatically through the existing derived scenario collection.

Changes

Layout repair scenario

Layer / File(s) Summary
Add layout repair recipe
archify/recipes/scenarios.mjs
Adds the layout-repair recipe with architecture metadata, bilingual copy, repair guidance, and signals for overflow, edge-through-node, and label overlap conditions.

Priority: ⬇️ Low — Defer this narrow bilingual recipe addition because it only expands guidance for diagram layout-repair questions without changing code paths, schemas, or acceptance rules.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 876e4

The new layout-repair recipe is not ready to merge because its routing guidance is incomplete and the added catalog entry leaves existing count assertions failing.

Full details: Contribution Scope

Explanation

The PR explains the user problem, focused behavior, and compatibility impact. However, the implementation does not fit the repository's generated-artifact scope. The changed source contains 12 recipe IDs, while docs/guide.html still contains 11 and archify.zip still contains the pre-change recipe source. scripts/build-guide.mjs imports publicGuideData() and generates docs/guide.html, and the contribution guide requires freshness checks for packaged runtime changes. The feature commit changes only archify/recipes/scenarios.mjs and claims that no generated artifacts are needed.

Resolution

Regenerate and commit the affected guide output and packaged archive. Update the guide-page count assertion or make it derive from the shared recipe source, then run the focused guide checks and the required package/freshness checks. Update the PR's Tests run and Generated artifacts sections with the actual results and list the regenerated files. State the preserved no-match/fallback behavior and the simple rollback action if the maintainer considers that behavior applicable.

Full details: Validation Evidence

Explanation

The PR does not meet the required validation and freshness evidence. The changed archify/recipes/scenarios.mjs is an input to scripts/build-guide.mjs, but the PR changes no generated output. docs/guide.html still contains 11 recipes and no layout-repair; scripts/guide-template.html still says “Eleven”; and archify.zip contains an older archify/recipes/scenarios.mjs without layout-repair. Downstream assertions also remain stale: archify/test/guide.test.mjs expects 11 recipes and 2 architecture recipes, archify/test/guide-page.test.mjs expects 11, and archify/test/cli.test.mjs expects scenario recipes (11). These changed-code effects contradict the reported checks and would invalidate the required full runtime/generated-content check. The PR description reports manual CLI results, but it provides no observed final-head CI result or npm test result.

Resolution

Update all affected recipe-count and architecture-count assertions, add focused regression coverage for English and Chinese layout-repair recommendations and preserved existing recommendations, update scripts/guide-template.html, regenerate and commit docs/guide.html with the new recipe, rebuild archify.zip with the changed recipe, and list the regenerated files. Then run cd archify && npm ci && npm test on the final head and provide the exact result or a linked final-head CI run. Keep visual evidence marked Not applicable with the non-visual explanation.

Update the downstream recipe-count assertions.

SCENARIO_RECIPES includes every RAW_RECIPES entry, so this addition changes the catalog from 11 to 12 recipes and the architecture count from 2 to 3. archify/test/guide.test.mjs Lines 11-17 still assert the old values, so the guide test will fail. Update those expectations in this change. Responsible role: author.

Smallest fix
-  assert.equal(SCENARIO_RECIPES.length, 11);
+  assert.equal(SCENARIO_RECIPES.length, 12);
-    { architecture: 2, workflow: 3, sequence: 2, dataflow: 2, lifecycle: 2 },
+    { architecture: 3, workflow: 3, sequence: 2, dataflow: 2, lifecycle: 2 },

As per path instructions, this additive recipe changes a downstream contract, so update the affected test in the base-to-head change.

Complete the via direction contract at both endpoints.

The English and Chinese prompts constrain only the first waypoint with via[0]. They do not state that the final route segment must enter the target endpoint perpendicular to its declared side. A repair can satisfy the source-side rule and still violate endpoint-side-direction. Add the final-segment rule to both prompts.

As per path instructions, via requires both the first and final route segments to be perpendicular to their declared sides.

Also applies to: 271-271
