Audit of docs/ found 32 diagrams: 23 already in mermaid, 9 in ASCII
art (box-drawing chars / +-pipe boxes). Converting all 9 to mermaid
so GitHub renders them as actual diagrams in the docs preview.
Files affected (9 diagram blocks across 6 files):

Conversion notes:
- Linear flows → flowchart TD/LR. Per-step annotations that the
ASCII had as floating text between arrows are now edge labels —
cleaner and easier to read.
- architecture.md block 4 (signer drivers) → flowchart LR with a
subgraph for the Driver interface. Cleaner than a class diagram
for the "code uses one of these implementations" semantics.
- ci-pipeline.md tree → flowchart TD. Adds a dotted '-.depends
on.->' arrow making the go-build-and-test → deploy-vendor-e2e
dependency visually obvious (was a parenthetical in the ASCII).
- est.md WiFi/RADIUS → flowchart LR with EAP, Radius, trusts,
and EST as four distinct labeled arrows. The 'trusts' annotation
was floating off to the side in the ASCII; now it's the arrow
label between Radius and certctl CA.
- All semantic detail preserved: every node label, arrow direction,
inline annotation, and multi-line cell content carries through.
Verified: post-conversion audit shows 32 mermaid blocks, 0 ASCII.
Diff is symmetric — 108 inserts, 123 deletes — because mermaid is
slightly more compact than the box-drawing characters it replaces.
GitHub renders mermaid blocks natively in markdown previews since
2022, so all 9 diagrams now render as real flowcharts in the docs
view rather than as monospaced character art.
EST RFC 7030 hardening master bundle Phase 12 — comprehensive operator-
facing documentation for the Phases 1-11 backend work that shipped on
2026-04-29.
NEW docs/est.md (19 sections, ~810 lines): Concepts (host vs user
enrollment, profile-driven policy, multi-profile dispatch); 5-minute
single-profile Quick start with curl + openssl recipes; Multi-profile
dispatch (CERTCTL_EST_PROFILES=corp,iot,wifi setup with PathID rules
enforced at boot); Authentication modes (mTLS / Basic / both / empty
with cross-check semantics); RFC 9266 channel binding (failure-mode
HTTP mapping table — ErrChannelBindingMissing/Mismatch/NotTLS13 →
400/409/426); WiFi/802.1X recipe with end-to-end FreeRADIUS integration
(EAP-TLS supplicant config, mods-available/eap tls-common block, CRL
distribution endpoint cross-ref, troubleshooting playbook); IoT bootstrap
recipe (factory provisioning, first boot, steady-state renewal,
compromise/decommission via bulk-revoke, recommended cert lifetimes
per master prompt §7.7); serverkeygen for resource-constrained devices
(CMS EnvelopedData wrap, RSA-only at this revision, zeroize discipline,
Phase-1 cross-check refusing _SERVERKEYGEN_ENABLED=true with empty
_PROFILE_ID); HSM-backed CA signing for EST cross-ref (signer interface
seam); Operator GUI tabbed surface tour (/est: Profiles / Recent
Activity / Trust Bundle); CLI + 6 MCP tools; Renewal device-driven
model (RFC 7030 §4.2.2 mandate, renewal-trigger ratios for laptops/IoT,
operator-push via webhook); Troubleshooting matrix (one row per typed
audit-action constant in internal/service/est_audit_actions.go);
TLS 1.2 reverse-proxy runbook cross-ref (channel-binding caveat
explained); Threat model (load-bearing properties: trust-anchor reload
fail-safety, per-profile counter isolation, mTLS cross-profile bleed
defense, source-IP limiter process-locality, server-keygen heap
residency, HTTP Basic in-process-only, legacy-anonymous-default
back-compat carve-out); V3-Pro deferrals; Appendix A (libest sidecar
reproducer + 5 integration test names); Appendix B (Cisco IOS 15.x +
16.x + Apple MDM + OpenWRT + libest <v3.0 wire-format quirks tested
in internal/api/handler/cisco_ios_quirks_test.go).
UPDATED docs/architecture.md: new "EST Server (RFC 7030) — Production
Deployment" section under the existing baseline EST section. Mermaid
diagram of multi-profile dispatch + mTLS sibling route + per-profile
gate ordering + audit + GUI + SIGHUP-equivalent reload. Existing
authentication paragraph updated with forward-ref to the hardening
section. Audit paragraph updated to enumerate the 13 typed est_*
action codes operators grep on. Trust-anchor reload semantics +
libest interop tested in CI both called out.
UPDATED README.md::Enrollment Protocols: replaced the one-line EST
row with the full production-grade surface description matching the
SCEP analog. Cross-references docs/est.md.
UPDATED docs/connectors.md::EST/SCEP Integration: extended the
EST-or-SCEP shared paragraph to point at the per-profile env-var
form for both protocols + linked the new architecture.md section.
NEW "Multi-profile EST dispatch + production hardening" subsection
mirrors the SCEP equivalent: 9-row env-var table, cross-ref to
docs/est.md.
G-3 docs-drift CI guard reproduced locally clean — every CERTCTL_EST_*
mention in docs maps back to internal/config/config.go, and every
defined env var is documented. The `<NAME>` placeholder convention
matches the SCEP idiom so the docs grep doesn't extract per-deploy
profile names as phantom env vars. No new env vars introduced —
this is a pure docs commit.
