chore(canvas-kit): sync vendored canvas-kit to 2026-07-07.6 - #22
Merged
Conversation
Re-vendor the canonical create-canvas-app kit (2026-07-05.1 -> 2026-07-07.6) into all six canvas extensions. This pulls in the recent kit hardening and feature work: - Strict action/state schema validation at the boundary (validate.mjs) - SSRF-safe fetch with per-redirect re-checks (net.mjs) - Atomic, concurrency-serialized storage tiers - githubStore for shared, multi-writer canvas state via the GitHub Contents API (github-store.mjs) Also update two smoke-test assertions to match the kit's stricter input validation (enum errors now carry the input path prefix; a present-but- undefined optional prop is now type-checked, so "rate current" omits the optional article key instead of passing undefined). Mechanical re-vendor from the canonical kit; no hand-edited kit logic. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

What
Re-vendor the canonical create-canvas-app kit (
2026-07-05.1→2026-07-07.6) into all six canvas extensions. The vendoredcanvas-kit/copies were behind the published kit and missed the recent hardening + feature work.Why
The extensions ship the kit verbatim (no npm, no build), so a published kit bump doesn't reach them until they're re-vendored. This sync brings in:
validate.mjs)net.mjs)githubStorefor shared, multi-writer canvas state via the GitHub Contents API (github-store.mjs)Scope

Ran the full CI check set locally (matches
validate.yml):node scripts/lint.mjs→ clean (93.mjs, 15.json)node scripts/validate-extensions.mjs→ 6 extensions validnode scripts/run-tests.mjs→ 6 test files passedThe site gallery test is unaffected (it reads extension card metadata, not kit internals).
