Plan 01-10 must_have #9 path-A swap-in (landed 2026-05-20 per debug
session 01-10-welcome-page-missing-mark). Closes the planning-coverage
gap where Plan 01-12 path-B (canonical tokens import) ran ahead of
01-10, leaving the welcome hero with a text placeholder 'Mokosh'
inside the rec-bg circle instead of the canonical 2×2 woven-square
mark from src/shared/brand/mokosh-mark.svg.
Why Option B (Vite ?url import) over manual WAR (A) or inline SVG (C):
- @crxjs/vite-plugin ^2.0.0-beta.25 auto-WARs transitively-reachable
resources from extension pages — no manifest.json edit needed.
- Vite default-inlines small SVGs (~600 bytes < 4096 byte default
assetsInlineLimit) as data:image/svg+xml URLs in the welcome chunk
— no extra HTTP request, no extra WAR entry.
- Hashed asset fallback works automatically if the SVG grows past
the inline limit in future revisions.
- Existing font-bundling precedent (dist/assets/Lora-*.woff2 +
IBMPlex*.woff2) proves the Vite + crxjs pipeline.
Files modified:
- src/welcome/welcome.ts — added markUrl import + populateMark() that
walks [data-mokosh-slot='mark'] and injects an <img>.
- src/welcome/welcome.html — added explanatory comment block; preserved
the data-mokosh-slot wrapper for forward-compat (the placeholder
span remains as the JS-fail-gracefully fallback).
- src/welcome/welcome.css — added .welcome-hero__mark-img rule
(60% sizing inside the existing styled circle wrapper).
- src/welcome/copy.ts — added 'welcome.hero.mark.alt' COPY key
(Russian per D-03 Sober voice).
- globals.d.ts — added *.svg?url ambient module declaration
(Vite recommended pattern; keeps tsconfig.json types: ['chrome']
clean by not requiring vite/client triple-slash directives).
- tests/uat/extension-page-harness.ts — extended A17 with A17.8
sub-check verifying the canonical mark SVG is bundled into the
welcome chunk (data URL OR file URL form) AND that the canonical
viewBox='0 0 32 32' is preserved through bundling.
Acceptance gates passed:
- npx tsc --noEmit exit 0
- npm run build exit 0
- SKIP_BUILD=1 npm test → 150/150 GREEN
- npm run test:uat → 24/24 GREEN including A17.8
- Tier-1 hook-string grep gate PASS (no FORBIDDEN_HOOK_STRINGS
in production bundle).
- Manifest valid JSON; web_accessible_resources auto-bundled.
- Pre-checkpoint bundle gates 1/2/3: vendor pre-existing hits
(JSZip + ts-ebml) confirmed identical pre-change via git stash
baseline; not caused by this fix.
Forward-looking deferred (out of scope):
- Issue 2 dark-surface contrast (e.g. chrome.notifications icon128
may need a light-stroke variant). The welcome hero's rec-orange
BG already provides high contrast with the dark ink stroke — this
is correct design. Per the orchestrator's explicit constraint,
light-variant mark for dark notification panels is deferred to
Phase 5.
