Subject: [PATCH] fix(scripts): inject GIT_SHA in dogfood-build.sh so
 provenance check passes (#2996)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Scripts-only PR — CI intentionally does not run for scripts/ (path filter covers rust/** and docs only). Manually verified: dogfood-build.sh builds, injects GIT_SHA, verifies provenance, and documents CLAW_CONFIG_HOME isolation. Zero stderr with isolated config.

 # dogfood-build.sh — Build claw from current checkout and verify provenance.
-# Usage: bash scripts/dogfood-build.sh
-# On success: prints the verified binary path. Use as:
-#   CLAW=$(bash scripts/dogfood-build.sh) && $CLAW version --output-format json
+#
+# Injects GIT_SHA at build time so version JSON is non-null.
+# Suppresses Cargo compile noise on stderr.
+# Prints the verified binary path on success. Use as:
+#
+#   CLAW=$(bash scripts/dogfood-build.sh)
+#
+# Then dogfood with config isolation (avoids real user config bleeding in):
+#
+#   CLAW_CONFIG_HOME=$(mktemp -d) $CLAW plugins list --output-format json
+#
