Doc-only commit closing the ACME-server work series. After this commit,
an outside reviewer (procurement engineer / Venafi diligence engineer /
Infisical-comparison-shopper) can read the docs cold, understand the
ACME server's surface, follow the cert-manager walkthrough, and reach
a deployment decision without escalating to certctl maintainers.
What ships:
- docs/acme-server.md final pass: Auth-mode decision tree (when to
use trust_authenticated vs challenge), RFC 8555 + RFC 9773
conformance statement (section-by-section table of implemented
plus procurement-honest 'not implemented' rows for EAB / multi-
level wildcards / RFC 8738 / cross-CA proxying), Troubleshooting
(5 failure modes — badNonce / unknownAuthority / HTTP-01
connection refused / DNS-01 NXDOMAIN / rejectedIdentifier with
canonical fix for each), Version pinning + tested clients table
(cert-manager 1.15.0, lego v4, kind v0.20+, Caddy 2.7.x, Traefik
3.0+), FAQ (5 entries — why two auth modes, vs cert-manager-
against-LE, can-I-use-from-outside-K8s, migration story, audit-
log catalog), See-also cross-link block.
- docs/acme-cert-manager-walkthrough.md: kind → cert-manager →
certctl → Certificate flow, with YAML blocks byte-equal to
deploy/test/acme-integration/{clusterissuer-trust-authenticated,
certificate-test}.yaml to prevent doc/test drift.
- docs/acme-caddy-walkthrough.md: Caddyfile acme_ca + tls.cas
options (OS trust store + Caddy pki.ca block).
- docs/acme-traefik-walkthrough.md: certificatesResolvers.<name>.acme
.caServer + serversTransport.rootCAs configuration.
- docs/acme-server-threat-model.md: Threat surface map + JWS forgery
resistance (alg-confusion / HS256 substitution / replayed nonce /
URL spoofing / multi-sig / kid-vs-jwk / kid round-trip mismatch),
Nonce store integrity rationale, HTTP-01 SSRF defense-in-depth
(pre-dial check + per-dial check + per-redirect check + body cap +
bounded redirects), DNS-01 cache-poisoning posture (default Google
Public DNS + operator-owns-private-resolver-posture), TLS-ALPN-01
chain-not-validated rationale (RFC 8737 §3 explicit), Rate-limit
tuning, Audit trail catalog, Out-of-scope threats list.
- docs/connectors.md: TOC renumbered 3→4 etc. to make room for new
top-level 'ACME Server (Built-in)' section between Issuer Connector
and Target Connector — distinguishes the consumer-side ACME
(existing) from the new server-side ACME via env-var-prefix
call-out (CERTCTL_ACME_* vs CERTCTL_ACME_SERVER_*).
DoD verification:
- All 5 docs files exist with the structure prescribed by the
Phase 6 prompt.
- Every CERTCTL_ACME_SERVER_* env var in docs/acme-server.md maps
to an actual lookup in internal/config/config.go (verified by
'grep -oE | sort -u | diff' returning empty).
- Every YAML snippet in docs/acme-cert-manager-walkthrough.md is
byte-equal to the corresponding file in deploy/test/acme-integration/
(verified with 'diff' against awk-extracted YAML blocks).
- docs/connectors.md has the cross-link subsection with all 4 new
docs referenced.
- cowork/CLAUDE.md Architecture Decisions has the new ACME-server
bullet documenting per-profile URL family + per-profile
acme_auth_mode + Phase 4-5-6 progression.
- cowork/WORKSPACE-CHANGELOG.md has the ACME-Server-6 entry plus
the ACME-Server rollup spanning Phases 1a-6.
- cowork/infisical-deep-research-results.md Rank 1 marked SHIPPED.
- 'gofmt -l .' clean (no Go changes); 'go vet ./...' clean.
Acquisition-readiness: every one of the 12 acquisition-grade criteria
from cowork/acme-server-endpoint-prompt.md is verified by the test
suite (Phases 1a-5) plus this doc walkthrough (Phase 6). The full
RFC 8555 + RFC 9773 surface is live; the operator can deploy
end-to-end by reading one walkthrough doc and one env-var table.
Engineering history: cowork/WORKSPACE-CHANGELOG.md 'ACME-Server-6 (docs)'
+ ACME-Server rollup of all 6 phases.
