First real-credential rotation on the safe-candidate ladder: full create→verify→store→revoke against a real Gitea PAT on git.churchofmalware.org (self-owned, no 2FA). To keep blast radius at zero, the run targets a purpose-made THROWAWAY token — a genuine token used by nothing — so the driver's real lifecycle earns LIVE-REAL without risking any in-use PAT (which is also referenced across .git-credentials, embedded git remotes and tea config, and needs the multi-reference blast-and-cutover, still to build). - lab/lab-rung3-gitea-real.sh: env-only secrets, isolated throwaway gopass store, independent cutover check (new->200, old->401), sealed backup. - proofs.go + ROTATION-PROOFS.md: gitea promoted LIVE-VM -> LIVE-REAL, LIVE-REAL section added; "no driver carries this yet" removed.

# lab-rung3-gitea-real.sh — RUNG 3 of the safe-candidate ladder, against a REAL Gitea.
|
|
#
|
|
# The first REAL-credential rotation: create → verify → store → REVOKE a genuine Gitea
|
|
# PAT via the real Gitea API. To keep blast radius at zero on this first run, point it at
|
|
# a PURPOSE-MADE THROWAWAY token (make one in the Gitea UI, used by nothing) — a real
|
|
# token whose whole lifecycle we prove, with nothing depending on it. That is what earns
|
|
# the `gitea` driver its LIVE-REAL proof without risking any in-use token or a git push.
|
|
#
|
|
# ALL secrets come from the ENVIRONMENT ONLY (never argv, never written to the script),
|
|
# and are staged into an ISOLATED throwaway gopass store — the real store is never touched.
|
|
#
|
|
# Required env:
|
|
# GITEA_BASE e.g. https://git.churchofmalware.org (scheme://host[:port])
|
|
# GITEA_USER your Gitea username
|
|
# GITEA_TOKEN the THROWAWAY PAT value being rotated
|
|
# GITEA_TOKEN_NAME the exact name of that PAT in Gitea (needed to DELETE it)
|
|
# GITEA_PW your Gitea ACCOUNT PASSWORD (basic auth for create/delete)
|
|
# Optional:
|
|
# GITEA_INSECURE=1 pass -k to the independent curl checks (self-signed TLS)
|
|
#
|
|
# Safety: self-owned account + your explicit authorization only. If the account has 2FA,
|
|
# basic-auth token management will fail — that is correct (Hard Rule 5, never bypass MFA);
|
|
# fall back to the guided worklist for manual rotation.
