ci/woodpecker/pr/ci Pipeline was successful
Blocker (rev-security-01 review 259): admin token, generated password and minted seat token travelled curl ARGV (three Authorization sites, -u at the mint, inline -d bodies), leaking to /proc cmdline and bash -x traces — the durable password under must_change_password:false is a live credential. All three now travel in 0600 staging files: --config for the Authorization header (the landed gitea_write_auth_config pattern), a user= directive for basic auth at the mint, --data @file for bodies. Unlinked after each use; M6 asserts no call is unauthenticated and no body is inline. Scope pin (SF2 + rev-security-01 M1, same defect): a mutant writing the REQUESTED scopes passed green because the grep target appears in both sets. M7 now asserts write:issue (requested, not granted) is ABSENT; mutant killed. SF3: hyphenated instance overrides map hyphen->underscore exactly like seat-logins.sh (url_override_var); M8 pins it; the uppercase-only mutant dies at the invalid-variable-name refusal again, now by design. SF1: mint-seat-credential.sh mode 755 (update-index), README invocation updated to name the now-required MOSAIC_SEAT_EMAIL_DOMAIN. Framework-PR firewall answer (rev-security-01): the email domain has NO default — unset is rc=3 with a named variable (M9); the instance host map stays per the seat-logins.sh precedent already on next. Estate domains belong to the estate, not the tree.

# Hermetic regression for mint-seat-credential.sh: mock curl on PATH, sandboxed
|
|
# brain home, no tea, no network, no real credentials.
|
|
#
|
|
# Pins:
|
|
# M1 the seat slot is written from the mint RESPONSE (token, granted scopes,
|
|
# principal), each file mode 600, and the identity check passes.
|
|
# M2 the admin token is read from MOSAIC_ADMIN_SEAT's slot, never hardcoded;
|
|
# a missing admin token is reported per instance and exits nonzero.
|
|
# M3 MOSAIC_GITEA_INSTANCES limits which instances are touched, and the URL
|
|
# override MOSAIC_GITEA_URL_<INSTANCE> is honoured.
|
|
# M4 no admin seat configured is a usage error (rc=3), nothing written.
|
|
# M5 the admin token value never appears on stdout or stderr.
|
|
# M6 secrets never touch argv: no Authorization header, no -u user:pass, no
|
|
# inline --data JSON carrying the password, on any curl invocation; auth
|
|
# travels in --config files and bodies in --data @files (#1343 class,
|
|
# rev-security-01 review 259 blocker).
|
|
# M7 the scopes record discriminates: a requested-but-not-granted scope
|
|
# (write:issue) must be ABSENT from .scopes — the pin is on the RESPONSE,
|
|
# and a mutant writing the requested set fails here (both reviewers).
|
|
# M8 hyphenated instance names resolve their override through the underscore
|
|
# variable, matching seat-logins.sh (SF3).
|
|
# M9 MOSAIC_SEAT_EMAIL_DOMAIN is required: unset is a usage error (rc=3),
|
|
# nothing written (framework-PR firewall answer).
