+name: 'Bootstrap pip JFrog routing (pre-setup-python)'
+description: |
+  Acquire a JFrog OIDC access token and pre-configure pip + netrc so that any
+  pip invocation routes through the JFrog db-pypi mirror instead of pypi.org —
+  including actions/setup-python's internal "Upgrading pip" step, which runs
+  before any other action gets a chance to redirect pip.
+
+  Why this exists: the Databricks hardened runner groups (larger-runners,
+  databrickslabs-protected-runner-group) block egress to pypi.org by design;
+  the go/hardened-gha policy is that all package fetches go through JFrog.
+  Without this pre-bootstrap, setup-python's bundled "pip install --upgrade pip"
+  hits pypi.org and dies with SSL EOF before .github/actions/jfrog-auth
+  ever gets to configure pip.
+
+  Reuses the OIDC exchange script from .github/actions/jfrog-auth/jfrog-auth
+  to avoid duplicating curl logic that we keep in sync with UCX. The main
+  jfrog-auth composite still runs later in the same job (idempotent for pip;
+  primary for Maven, which needs setup-java to have run first).
+
+  Caller job MUST declare:
+    permissions:
+      id-token: write

+# --- badSig overrides for POMs byte-mutated by db-maven JFrog mirror -----
+#
+# These six .pom files fail pgpverify-maven-plugin with "PGP Signature
+# INVALID" — cryptographic verification of the .asc against the bytes
+# fails. The corresponding .jar files for the same artifacts verify
+# OK (they're binary and pass through JFrog untouched).
+#
+# Root cause confirmed 2026-05-18 via the diag-pgpverify-pom-transit
+# workflow (run 26056343517 on branch ci-fix-jfrog):
+#
+#   * .pom sha256 from db-maven DIFFERS from Maven Central (size delta
+#     -348 to +170 bytes per file)
+#   * .pom.asc sha256 from db-maven MATCHES Maven Central (signatures
+#     untouched)
+#   * Hex dump shows LF → CRLF conversion at every line end, plus
+#     additional content normalization (whitespace / XML formatting)
+#   * Standalone `gpg --verify` on the db-maven bytes produces "Signature
+#     made … using RSA key … Can't check signature" — the .asc was
+#     computed against the original Maven Central bytes, not the
+#     JFrog-mutated ones.
+#
+# JFrog db-maven applies some form of text-resource transformation to
+# .pom files on the mirror side, which breaks the upstream PGP signature
+# chain. The .jar signatures remain trustworthy (binary, untouched), so
+# code-execution integrity is still gated. POM-declared dependency
+# coordinates inherit JFrog-as-trust-boundary status (an attacker who
+# compromises db-maven could regress to a previously-trusted-but-now-
+# vulnerable signed JAR via POM rewrite — risk is real but bounded
+# to artifacts already in the mirror's allowlist).
+#
+# `badSig` here means "tolerate that the .pom signature does not
+# cryptographically verify" — narrower than `noSig` ("tolerate no
+# signature at all"). The artifact must still HAVE a .asc on the
+# server; this only suppresses the crypto-failure error.
+#
+# Action item: file a JFrog admin ticket asking db-maven to disable
+# text-artifact transformations so POM bytes pass through verbatim, then
+# delete this block (POMs will verify again).
+#
+# Versions are pinned at the exact artifact:packaging:version level so
+# future releases inherit strict verification rather than the override.
