Codex P0 mini-gate Round 3 BLOCK fix: P0.2 plan calls for
tools/fetch-skia-artifact.sh, and Phase A CI step invokes it before
measuring bundle size — but the script did not exist in the OP repo.
Phase A cannot start without it.
Variant A (GitHub release asset) selected per probe notes §3.1
"Artifact Distribution Strategy": <1 MB gzip, free hosting, no extra
git-lfs setup overhead.
Behavior:
exit 0 artifact present and SHA matches OR no release pinned yet
(Phase E will publish; dev loop uses skia-bindings from-source)
exit 1 artifact present but SHA mismatched, or fetch failed after
a download attempt
Phase E will overwrite RELEASE_TAG / RELEASE_FILE / EXPECTED_SHA256
constants with the published release asset metadata. Until then dev
builds run skia-bindings from source (no fetch needed).
Smoke run: `bash tools/fetch-skia-artifact.sh` →
"no release tag pinned yet — Phase E will publish; dev builds use
skia-bindings from-source path" + exit 0.

# The actual release asset is published in Phase E once the production

# build pipeline lands; for Step 1b kickoff (Phase A onward) the dev

#
|
|
# Exit semantics:
|
|
# 0 vendor/skia-wasm/libskia-current.a is present and (when
|
|
# EXPECTED_SHA256 is set) matches the pinned hash; OR the artifact
|
|
# is absent and Phase A from-source build is the active path.

|
# 1 artifact present but SHA mismatched, OR network/git-lfs failure
|
|
# after a download was attempted.

# Phase E will populate EXPECTED_SHA256 + RELEASE_TAG + RELEASE_FILE
|

# constants below; until then the script logs and returns 0 so dev
