fix(#1367): mint-seat-credential — secrets out of argv; discriminating pins (review 259 blocker, review 260 SF1-SF3)
ci/woodpecker/pr/ci Pipeline was successful
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.
