Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The current head changes management authentication, startup behavior, and smoke-test credential handling in addition to pinning CI runners. Credential-free application instances can still authorize management writes outside the guarded startup path, and the smoke test can send an administrator token to another process if the selected port is reused; the PR is not merge-ready until these security risks are fixed or explicitly accepted. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

🔍 Runner-only scope is no longer narrow
The head adds a production authentication overhaul after the documented runner-only commit. Its startup and API changes require separate exact-head review evidence.

🟥 Readonly registry disables shared write token
When ADMIN_TOKENS contains only readonly principals, has_write_capable_admin ignores a valid ADMIN_TOKEN. Public deployments then fail startup despite valid write authentication.

In `@docs/security/threat-model.md`:
- Line 50: Update the NIST reference in the threat-model bibliography from the
withdrawn 2020 SP 800-63B edition to the final SP 800-63B-4 publication,
including the corresponding title, publication year, and official NIST citation
details while preserving the existing bibliography format.
In `@scripts/smoke.sh`:
- Line 35: Update the smoke-test startup flow around the cargo build and gateway
readiness handling to verify the child gateway process emits its exact readiness
line before requesting or sending the administrator token. Do not rely solely on
the /healthz response; retain and use the actual address assigned by the
gateway, including a dynamically allocated port such as :0 when available, so a
bind failure cannot redirect credentials to another listener.
In `@src/credentials.rs`:
- Around line 163-190: Extend the fuzz coverage for admin-token parsing by
invoking CredentialRegistry::bootstrap_secrets from fuzz_parse_admin_tokens.rs
and the corresponding stable proptest mirror in tests/fuzz_invariants.rs, using
the same generated inputs. Ensure these paths exercise
validate_admin_header_secret and validate_admin_token_list_header_secrets while
preserving the existing parse_admin_tokens_strict coverage.
In `@src/lib.rs`:
- Around line 3393-3396: Update src/lib.rs lines 3393-3396 and 3421-3425 so the
startup configuration reads WAF_IDS_STATE_PATH and MAX_BODY_BYTES from the
approved KV store or process-local registry instead of directly from environment
variables; preserve the existing trimming, parsing, and optional-value behavior.
- Around line 2627-2628: Update admin_authorized in src/lib.rs (lines 2627-2628)
so administrative write requests always require a valid X-Admin-Token, including
loopback requests and when no credential is configured. Update the corresponding
documentation in README.md (line 68) and docs/deployment/production.md (line 62)
to describe the mandatory token requirement.
In `@tests/binary.rs`:
- Line 51: Replace the blocking Command::output() call in the test with
spawn-based child management, poll try_wait until a bounded timeout, and retain
the captured output needed for assertions. If the timeout expires, kill the
child, reap it, and fail the test explicitly.

Reachability: External · Exploitability: Difficult
게이트웨이 readiness 행을 확인한 후 관리자 토큰을 전송하십시오.
PORT를 해제한 뒤 cargo build가 실행되므로 공격 프로세스가 해당 포트를 선점할 수 있습니다. /healthz 응답만 신뢰하면 게이트웨이의 bind 실패를 숨길 수 있고, 이후 관리자 토큰이 공격자 리스너로 전송될 수 있습니다. 자격 증명 요청 전에 자식 프로세스의 정확한 readiness 행을 확인하고, 가능하면 :0으로 할당된 실제 주소를 사용하십시오.

Superseded by clean runner-only replacement #153.
This branch originally ended at runner-only head
b663f9d200e5f385c7dd067d074940a02836c68e, but later advanced tod8d82cba1e8426d3ee0bedee428f689450c588f6when the fail-closed-auth PR #138 was merged into this temporary feature branch during stack repair. The branch therefore no longer contains only the runner-control delta and must not be used as the canonical prerequisite.Protected
mainwas not changed by that feature-branch merge. #153 starts at the exact clean runner-only headb663f9d…against protectedmain@cc15cc2c34daf8c104eeb83d52a6a66f3cd6e128. The auth delta is separately restored as main-targeted replacement #155. No check/review evidence from this contaminated successor transfers.
