fix(ui): compile app fonts without Google requests (AL-1914) by cobmojo · Pull Request #1916 · Asymmetric-al/core

cobmojo · 2026-09-28T21:12:10Z

Closes #1914.

Root-layout compilation currently depends on Google's font responses. Valid extensionless font URLs reproduce the pinned Next compiler failure before application routes render. This change checks in the existing Inter, Syne and Geist Mono files and loads them through shared next/font/local modules, so compilation no longer fetches those fonts.

The 16 unmodified WOFF2 files (349,868 bytes) retain all 56 weight/subset faces, Unicode ranges, three public CSS variables, three metric-adjusted Arial fallbacks, swap display and the two Inter/Syne Latin preloads. The manifest records hashes, source URLs, embedded metadata and upstream SIL OFL 1.1 notices. Each subset has a literal loader so Unicode selection and preload ownership stay intact. The three apps consume @asym/ui/fonts; framework/dependency pins and typography remain unchanged.

Validation and provenance:

Current source is caf9c71c6ebdd5f064ec956a8d7323f7271a390a, tree 9075ae087470e64a943b314bb510202b32a9fe0f, after an ordinary merge of develop bd9acc44313761d3371996c85376373782da02fb. All 53 font paths are unchanged from reviewed implementation 03bc6cc433e769ad63c5a503f7ccca7ce49e7b78; all 64 incoming guidance paths exactly match develop.
Current focused verification: 39 tests passed, skill mirrors and strict OpenSpec validation passed, normal commit hooks passed, and the whole-repository Shadscan score remained 43 at floor 43.
The unchanged production font implementation passed bun run verify:fonts:offline with Next 16.3.0-preview.9 in a Linux network namespace containing only loopback. The actual shared export compiled, all 56 faces loaded, all 16 asset hashes and both preloads matched, and deleting one required asset caused compilation to fail.
An independent Google/local browser comparison matched all 59 emitted font/fallback descriptors after normalizing only source URLs and internal aliases. Both cases loaded all 56 font faces, had no external requests or browser errors, and produced byte-identical screenshots. Root also independently verified the 16 committed binary blobs and original face/preload hashes.
The normal full pre-push ci:preflight passed on published caf9c71c: all three application builds, 4,344 tests and four existing skips. Fresh GitHub CI and hosted application qualification still need their own results.

The failing CI log truncated its full Google URL, so the isolated reproduction does not establish Google's exact response in that run. Offline font proof does not qualify Support Hub, Boneyard, authentication or hosted previews. Those remain normal application/CI checks, including the shared #1915 QA dependency; no gate is waived.

Deploy Checklist (for PRs to `production` or `develop`)

Current-head GitHub CI and applicable preview smoke pass
Base branch confirmed: develop; production release is separate
Migrations, new environment variables and release controls reviewed (N/A)
Font provenance, licensing, file hashes, rendering and preload behavior verified
Rollback: revert the shared font modules and app imports; no data migration
Ready for hosted preview after shared fix(eve): stabilize preview builds and verification (AL-1913) #1915 verification is integrated

Draft while the shared preview qualification dependency remains unresolved.

Confidence Score: 5/5

The reviewed code appears safe to merge once the PR’s outstanding CI and hosted-preview checks pass.

Summary

The PR replaces Google font compilation in all three Next app layouts with licensed local assets exposed by @asym/ui/fonts.

Adds subset loaders, fallback metrics, provenance, and focused font verification.
Preserves the existing typography tokens and keeps normal application and hosted-preview checks applicable.

📝 Summary

The admin, donor, and missionary apps now load Inter, Syne, and Geist Mono from shared local font files. App compilation no longer depends on Google Fonts requests.
The change preserves the existing font families, weights, Unicode subsets, CSS variables, fallback metrics, swap behavior, and Inter/Syne Latin preloads. It adds font licenses, source and hash records, and an offline verification tool.
Unit tests cover font assets and configuration. Full app builds, fresh CI, and hosted application checks remain pending.

Walkthrough

The three applications now load Inter, Syne, and Geist Mono from shared local assets. The UI package records font metadata and exposes shared font variables. An offline verification script checks compilation, browser font loading, asset hashes, and missing-file failure.

Changes

Shared local font delivery

Layer / File(s)	Summary
Shared font package and asset contract `packages/ui/fonts/*`, `packages/ui/package.json`, `tests/unit/packages/ui/local-fonts.test.ts`	Adds local font loaders, Arial metric fallbacks, license files, and a manifest with font asset metadata. Exports `fontVariables`. Tests check asset hashes, licenses, fallback metrics, and loader configuration.
App layout integration `apps/{admin,donor,missionary}/app/layout.tsx`, `packages/ui/styles/README.md`, `tests/unit/packages/ui/local-fonts.test.ts`	The three app layouts use shared font variables instead of Google font loaders and remove Google Fonts preconnects. Tests check the layouts’ font imports.
Offline verification and maintenance `scripts/verify/local-fonts-offline.mjs`, `package.json`, `CONTRIBUTING.md`, `README.md`, `packages/ui/fonts/README.md`, `openspec/changes/self-host-app-fonts/*`	Adds an offline build and browser check, including a missing-asset failure check, and wires it to a package script. Documentation and OpenSpec files describe the verification, font maintenance, and delivery requirements.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: ii-ricky-bobby-ii

Merge Risk: 🟡 Moderate · up to caf9c

Characters outside the selected subset may render in fallback fonts across all three apps. Give each family’s subset faces a shared CSS family before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to caf9c

The three apps now rely on bundled fonts instead of a network-dependent font build. The visible changes use fixed local assets and do not show a new path to privileged functionality. Asset provenance, complete verification, and deployment behavior are not fully established, so the risk is low rather than negligible.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — A defective shared font asset or export could affect builds or presentation in all three apps. The visible font flow does not show access to tenant data, credentials, or privileged operations.

Trust Boundaries and Controls

inferred — For the examined loaders, font sources are fixed local files rather than URLs or paths selected by a visitor. The removed Google Fonts preconnects narrow the font-related external connection hints in the layouts.

Resilience and Maintainability Implications

inferred — The offline verification design checks asset integrity and rejects external browser requests, but the supplied evidence does not establish that this check gates every deployment.

Full details: Linked Issues check

Explanation

The implementation matches the coding objectives in #1914: shared next/font/local loaders, three app layout integrations, preserved variables and fallback metrics, provenance and OFL records, manifest hashes, unit tests, and an offline verifier. The result cannot be fully established because all 16 required WOFF2 assets are excluded by !**/*.woff2, so their presence and byte integrity are not independently reviewable. The summary also reports that fresh GitHub CI and hosted application qualification remain outstanding.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 9 functions across 22 files. (15 skipped: 15 unsupported.)
