legal: addlicense headers + normalize legacy variants (Phase 0 RED-4)
Phase 0 closure (Path B2, post-rewrite):
addlicense sweep — adds the canonical certctl LLC copyright + BUSL-1.1
SPDX header to every production Go file. Template:
// Copyright 2026 certctl LLC. All rights reserved.
// SPDX-License-Identifier: BUSL-1.1
Coverage: 338 / 338 production Go files (cmd/ + internal/, excluding
*_test.go and **/testdata/**). Pre-sweep coverage was 22 / 338 (6.5%);
post-sweep is 338 / 338 (100%).
Normalized 22 pre-existing legacy headers (`// Copyright (c) certctl`
+ `// SPDX-License-Identifier: BSL-1.1`) and 1 file using a
`Certctl Contributors` attribution. The legacy SPDX ID `BSL-1.1`
is non-standard; the official SPDX identifier for Business Source
License 1.1 is `BUSL-1.1` (capital U). All 338 files now share the
canonical form.
Generated via:
addlicense -c "certctl LLC" -y 2026 \
-f cowork/legal/copyright-header.tpl \
-ignore '**/testdata/**' -ignore '**/*_test.go' \
cmd/ internal/
Verification:
find cmd internal -name '*.go' -not -name '*_test.go' \
-not -path '*/testdata/*' \
-exec grep -L '^// Copyright 2026 certctl LLC' {} \; | wc -l
Returns: 0
gofmt clean. Header additions are comments only, no compile impact.

ci: floor raise + doc drift (Phase 3 closure — TEST-H1/H2/M1/M2/M3/M4/L1, ARCH-H3/L1/L2/L3/L4)
Twelve findings from the architecture diligence audit's Phase 3 bundle
closed in one PR. All touch the CI workflows + small doc-drift fixes
across the production Go tree + migration headers.
CI workflow changes
====================
TEST-H1 — Race detection on ./... -short
.github/workflows/ci.yml:106 was a 9-package explicit list. Audit
finding TEST-H1 flagged that 25+ packages (internal/auth/*,
internal/repository/*, internal/mcp, internal/scep, internal/pkcs7,
internal/api/router, internal/api/acme, internal/cli, internal/cms,
internal/config, internal/deploy, internal/integration,
internal/ratelimit, internal/secret, internal/trustanchor, all of
cmd/) silently dropped off race coverage.
Post-fix: 'go test -race -short ./... -count=1 -timeout 600s'.
76 testing.Short() guards already cover testcontainers + live-DB
integration suites, so -short keeps the long-running tests out.
TEST-H2 — Cross-platform build matrix
New 'cross-platform-build' job in ci.yml. Matrix:
ubuntu-latest + windows-latest + macos-latest, fail-fast: false.
Builds cmd/server + cmd/agent + cmd/cli + cmd/mcp-server on each.
Catches Windows-specific regressions (path separators, file
permissions, exec.Command semantics) the pre-Phase-3 Ubuntu-only
CI missed.
TEST-L1 — actions/setup-go cache: true (explicit)
setup-go v5 defaults cache: true; making it explicit so a future
setup-go upgrade can't silently flip it. Re-runs hit the Go module
+ build cache instead of recompiling cold.
TEST-M1 — Mutation-testing floor at 55%
security-deep-scan.yml::go-mutesting step rewritten. Removed
continue-on-error + per-package '|| true'. New post-loop check
extracts every 'The mutation score is X.YZ' line and fails the
step if any package drops below 0.55. Floor rationale: starter
ratio catches major regressions without rejecting the audit's
'this is OK' steady state; raise quarterly.
TEST-M2 — 3 advisory deep-scan gates promoted to blocking
Removed continue-on-error: true from:
- gosec (filtered to G201/G202/G304/G108 high-signal rules:
SQL-injection + path-traversal + pprof-exposed)
- osv-scanner (multi-ecosystem CVE; complements govulncheck
which is already blocking in ci.yml)
- trivy image scan (--severity HIGH,CRITICAL --exit-code 1)
continue-on-error count: 15 → 11.
ZAP / schemathesis / nuclei / testssl stay advisory because their
false-positive rates on https://localhost:8443-targeted DAST runs
are high.
TEST-M3 — Playwright harness stub
web/package.json adds '@playwright/test' devDep + 'e2e' / 'e2e:install'
npm scripts. web/playwright.config.ts ships single chromium project
with webServer block pointing at 'npm run dev'. web/src/__tests__/
e2e/smoke.spec.ts proves the harness wires through. The full 15-flow
suite ships in frontend-design-audit Phase 8 (TEST-H1 in THAT audit);
this is the wiring + a single smoke test as the regression floor.
New Makefile target: 'make e2e-test'.
Doc/code drift fixes
====================
TEST-M4 + ARCH-L2 — Skip inventory artifact + CI guard
scripts/skip-inventory.sh walks every t.Skip site under cmd/ +
internal/ + deploy/test/ and emits docs/testing/skip-inventory.md
grouped by package with file:line:expression triples. Current
inventory: 142 t.Skip sites, 76 testing.Short() guards.
scripts/ci-guards/skip-inventory-drift.sh regenerates and fails on
diff (excluding the 'Last reviewed' timestamp line which drifts
daily). The Markdown is the canonical acquisition-diligence artifact
for 'what tests are being skipped and why.'
ARCH-H3 — MCP catalogue floor reconciliation
Audit framing was '121 vs floor 150 — doc/code drift.' Live count
via the test's actual regex over all 5 tool files (tools.go +
tools_audit_fix.go + tools_auth.go + tools_auth_bundle2.go +
tools_est.go): 155 unique 'Name: "certctl_*"' declarations.
Pre-Phase-3 audit measured tools.go in isolation (121) and missed
the other 4 files (+34 unique names). The test at
internal/ciparity/surface_parity_test.go::TestSurfaceParity_MCP
passes today (155 ≥ 150). Added a clarifying comment near
mcpBaselineFloor explaining the measurement scope so future
reviewers don't repeat the audit's framing error.
STATUS: stale — no code drift, just a measurement scoping error in
the audit.
ARCH-L1 — panic() rationale comments
5 panic sites in production Go (excluding _test.go):
- internal/repository/postgres/tx.go:84
- internal/service/issuer.go:861 (mustJSON)
- internal/service/est.go:728 (mustParseTime)
- internal/service/acme.go:1288 (rand source failure — already documented)
- internal/pkcs7/certrep.go:270 (OID marshal — already documented)
Added ARCH-L1 rationale comments to the 3 sites that didn't have
them. All 5 are defensible impossible-path / rethrow / hardcoded-
constant guards.
ARCH-L3 — Migration IF-NOT-EXISTS carve-outs
4 migrations skip the literal 'IF NOT EXISTS' token but ARE
idempotent via different Postgres patterns:
- 000014_policy_violation_severity_check.up.sql: ALTER TABLE
ADD CONSTRAINT CHECK doesn't accept IF NOT EXISTS; idempotency
via DROP CONSTRAINT IF EXISTS preamble.
- 000018_audit_events_worm.up.sql: CREATE OR REPLACE FUNCTION
+ DROP TRIGGER IF EXISTS + CREATE TRIGGER + DO $$ pg_roles
existence check. CREATE TRIGGER doesn't take IF NOT EXISTS.
- 000030_rbac_admin_perms.up.sql: INSERT ... ON CONFLICT DO NOTHING.
- 000039_audit_crit1_perms.up.sql: same INSERT + ON CONFLICT pattern.
Added ARCH-L3 header comments to each explaining the carve-out so
reviewers don't flag the missing literal token.
STATUS: largely stale — migrations are already idempotent.
ARCH-L4 — TODO/FIXME → see #<descriptor>
5 TODOs rewritten to the allowed 'see #<descriptor>' pattern:
- internal/repository/postgres/auth.go:220 → see #bundle-2-scope-fk
- internal/connector/discovery/gcpsm/gcpsm.go:547 → see #gcpsm-pagination
- internal/service/audit.go:244 → see #audit-pagination-count
- internal/service/job.go:295, 299 → see #validation-job-impl
New CI guard scripts/ci-guards/no-todo-in-prod.sh grep-fails any
new TODO/FIXME in cmd/ + internal/ (excluding _test.go); allows
'see #N' / 'see #<descriptor>' patterns.
Sandbox limitation
==================
The 6.1 GB certctl working tree fills the sandbox volume; go1.25.10
toolchain download fails with 'no space left on device' (sandbox has
1.25.9; go.mod requires 1.25.10). Local 'go test' / 'go build' NOT
run in this commit. Operator must run 'make verify' on their
workstation before push per CLAUDE.md operating rules.
The smoke.spec.ts NOT executed in the sandbox (no chromium installed).
Operator runs 'cd web && npm install && npx playwright install
--with-deps chromium && npm run e2e' on first wire-up.
All CI guards (no-todo-in-prod, skip-inventory-drift, G-3
env-docs-drift, doc-rot-detector, and every existing guard) verified
clean by running each individually.

chore: rename Go module path to github.com/certctl-io/certctl
Mechanical sed across the main go.mod's module declaration, the f5-mock-icontrol
sub-module's go.mod, every Go file's import path (361 files), and a rebuild of
the checked-in f5-mock-icontrol binary so its embedded build-info reflects the
new module path. No behavior change.
Choice B from cowork/transfer-certctl-to-org.md, executed 2026-05-04. Choice A
(keep module path declared as github.com/shankar0123/certctl regardless of
repo URL) shipped on the day of the org transfer (2026-05-03) since we had no
external Go consumers; this commit closes that deferral.
Backward-compat: GitHub HTTP redirects continue to forward
github.com/shankar0123/certctl → github.com/certctl-io/certctl at the URL
level, but Go's module proxy uses the path declared in go.mod as the
canonical name. Pre-fix, anyone trying `go get github.com/certctl-io/certctl/...`
hit a "module path mismatch" error because go.mod said
github.com/shankar0123/certctl and the URL they fetched it from said
certctl-io/certctl. Post-fix, the canonical name and the URL agree, so
go get / go install / external Go consumers / Go-tooling integrations
work cleanly via either the new path (preferred) or the old path (which
redirects and Go follows the redirect for source fetch).
Anyone still importing the old path inside their own code keeps working
provided they update their go.mod's `require` line to match — the module
path declared in their consumer's go.sum / go.mod is the authoritative
import name, so a mass sed across their import statements is the migration
on the consumer side. No external consumers exist today.
Diff shape:
361 *.go files — import path replacement only
2 go.mod — module declaration replacement only
1 binary — deploy/test/f5-mock-icontrol/f5-mock-icontrol rebuilt
so embedded build-info reflects the new path (8618965 vs
8618933 bytes; 32-byte diff is the build-info change)
Total: 364 files, 730 insertions / 730 deletions, net-zero size, pure
mechanical substitution.
Verification:
gofmt: 17 files needed re-alignment after sed (the new path is one char
shorter than the old, so column-aligned import groups drifted). Applied
`gofmt -w` to fix.
go mod tidy: clean exit on both modules.
go vet ./...: clean exit.
go build ./...: clean exit.
go test -short -count=1 on representative packages: all green
(internal/domain, internal/validation, internal/crypto, internal/crypto/signer,
cmd/agent). Test output now reads `ok github.com/certctl-io/certctl/...`
confirming the module path resolves correctly.
binary: f5-mock-icontrol rebuilt; `strings | grep shankar0123` returns
nothing; `strings | grep certctl-io/certctl` shows the new module path
embedded in build-info.
Files intentionally NOT touched in this commit:
README.md / CHANGELOG.md / docs/ / etc. — already swept to certctl-io
URLs in commit

EST RFC 7030 hardening master bundle Phases 10-11: libest sidecar e2e
+ Cisco IOS quirk fixtures + ManagedCertificate.Source provenance + EST bulk-revoke endpoint + 13 typed audit action codes. Phase 10.1 — libest reference-client sidecar: - deploy/test/libest/Dockerfile: multi-stage Debian-bookworm-slim build of Cisco's libest v3.2.0-2 from source (autoconf/automake/ libtool + libcurl4-openssl-dev + libssl-dev). Runtime stage carries only estclient + bash + openssl + ca-certificates so the exec surface stays small + predictable. - docker-compose.test.yml libest-client entry (profiles: [est-e2e]) with bind mounts for /config/est (test workspace) + /config/certs (certctl CA bundle for TLS pinning); IP 10.30.50.9 (10.30.50.8 was already taken by certctl-agent). - deploy/test/est/.gitkeep keeps the bind-mount target tracked. Phase 10.2 — 5 integration tests (//go:build integration) in deploy/test/est_e2e_test.go: - TestEST_LibESTClient_Enrollment_Integration (cacerts → simpleenroll → cert-shape assertion) - TestEST_LibESTClient_MTLSEnrollment_Integration (mTLS sibling-route cert auth; skip when bootstrap cert absent) - TestEST_LibESTClient_ServerKeygen_Integration (RFC 7030 §4.4 multipart; skip when profile gate disabled) - TestEST_LibESTClient_RateLimited_Integration (4th enroll trips per-principal cap, asserts 429-shaped error) - TestEST_LibESTClient_ChannelBinding_Integration (libest --tls-exporter; skip when libest build lacks the flag). - requireESTSidecar guard skips the suite when the operator forgot --profile est-e2e; helpful error message includes the exact command to bring the sidecar up. Phase 10.3 — Cisco IOS quirk fixtures + 3 unit tests in internal/api/handler/cisco_ios_quirks_test.go: - testdata/cisco_ios_15x_pem_csr.txt: PEM body sent with Content-Type application/x-pem-file. Handler dispatches on body-prefix not Content-Type — accepts cleanly. - testdata/cisco_ios_16x_trailing_newline_csr.txt: extra trailing newlines after base64 body. strings.TrimSpace tolerates. - testdata/cisco_ios_crlf_b64_csr.txt: CRLF-wrapped base64. base64.StdEncoding handles CRLF + LF identically. Phase 11.1 — ManagedCertificate.Source provenance: - New domain.CertificateSource enum (Unspecified/EST/SCEP/API/Agent). - Migration 000023_managed_certificates_source.up.sql adds source TEXT NOT NULL DEFAULT '' so existing rows scan as CertificateSourceUnspecified — back-compat: bulk-revoke filter treats empty as "any source". - Postgres repo Insert/Update/scan paths all wire the new column. Phase 11.2 — EST bulk-revoke endpoint: - BulkRevocationCriteria.Source field (Source-only requests rejected as too broad — must accompany at least one narrower criterion). - service.bulk_revocation.resolveCertificates post-filter by Source (empty=any, no SQL change so existing CertificateFilter callers unaffected). - New BulkRevocationHandler.BulkRevokeEST method pins Source=EST + dispatches; new route POST /api/v1/est/certificates/bulk-revoke (M-008 admin-gated). openapi.yaml documented + parity-guard green. Phase 11.3 — 13 typed audit action codes in internal/service/est_audit_actions.go: - est_simple_enroll_success / _failed - est_simple_reenroll_success / _failed - est_server_keygen_success / _failed - est_auth_failed_basic / _mtls / _channel_binding - est_rate_limited - est_csr_policy_violation - est_bulk_revoke - est_trust_anchor_reloaded - ESTService.processEnrollment + SimpleServerKeygen + ReloadTrust split-emit BOTH the legacy bare action codes (back-compat for the GUI activity-tab chip filters that match by exact string + existing audit-log analysers) AND the new typed _success / _failed variants (operator grep target + per-failure-mode counter). Tests: - internal/api/handler/bulk_revocation_est_test.go — 5 cases (admin-true happy path pins Source=EST + non-admin 403 + empty-criteria 400 + invalid-reason 400 + method-not-allowed). - internal/service/est_audit_actions_test.go — 5 cases (SimpleEnroll legacy+typed emission / SimpleReEnroll typed / IssuerError typed-failed / PolicyViolation triple-emit / unique-string invariant). Pre-commit verification (sandbox): gofmt clean, go vet clean (excluding repository/postgres testcontainers limit), staticcheck clean across api/handler/api/router/domain/service/deploy/test, go test -short -count=1 green for every non-postgres Go package + integration build (`go build -tags integration ./deploy/test/...`) clean. G-3 docs-drift guard reproduced locally clean (Phases 10-11 added zero new env vars). Spec preserved at cowork/est-rfc7030-hardening-prompt.md. Phases 12-13 (docs/est.md + WiFi/802.1X / IoT bootstrap / FreeRADIUS recipes; release prep + tag) remain — post-2.1.0 work. |

EST RFC 7030 hardening master bundle Phases 5-7: end-to-end serverkeygen
+ profile-driven csrattrs + admin observability with per-status counters + reload-trust endpoint. Phase 5 — RFC 7030 §4.4 server-driven key generation: - internal/pkcs7/envelopeddata_builder.go is the inverse of the existing parser/decryptor: AES-256-CBC content cipher + RSA PKCS#1 v1.5 keyTrans + per-call random IV. Round-trip pinned in test (BuildEnvelopedData → ParseEnvelopedData → Decrypt returns the original plaintext byte-for-byte). - ESTService.SimpleServerKeygen runs the full §4.4 flow: parse client CSR → require RSA pubkey for keyTrans → resolve per-profile algorithm (RSA-2048 default; honors AllowedKeyAlgorithms) → in- memory keygen → re-build CSR with server pubkey → run existing issuer pipeline → marshal PKCS#8 → CMS-EnvelopedData wrap to a synthetic recipient cert wrapping the device's CSR-supplied pubkey → zeroize plaintext + PKCS#8 bytes → return CertPEM + ChainPEM + EncryptedKey. Typed sentinels ErrServerKeygenRequiresKey- Encipherment / ErrServerKeygenUnsupportedAlgorithm / ErrServerKeygenDisabled. - ESTHandler.ServerKeygen + ServerKeygenMTLS emit RFC 7030 §4.4.2 multipart/mixed with random per-response boundary; per-profile SetServerKeygenEnabled gate returns 404 when off (defense in depth even if the route was registered). - New routes POST /.well-known/est/[<PathID>/]serverkeygen + /.well-known/est-mtls/<PathID>/serverkeygen; openapi.yaml + openapi-parity guard updated. Phase 6 — Real csrattrs implementation: - New CertificateProfile.RequiredCSRAttributes []string + migration 000022_certificate_profiles_csrattrs.up.sql. The migration also lands the previously-unwired must_staple column (closes the 5.6 follow-up loop where the field shipped at the domain + service layer but the postgres scan/insert/update never persisted it). - domain.EKUStringToOID + AttributeStringToOID lookup tables: id-kp-* EKUs (RFC 5280 §4.2.1.12) + RFC 5280 DN attributes + RFC 2985 PKCS#10 attributes + Microsoft Intune device-serial OID. - ESTService.GetCSRAttrs replaces the v2.0.x nil/204 stub with a profile-derived SEQUENCE OF OID ASN.1 marshal. Unknown EKU / attribute strings dropped + warning-logged so a typo doesn't take down the entire endpoint. Phase 7 — Admin observability + counters + reload-trust: - internal/service/est_counters.go: estCounterTab (sync/atomic; 12 named labels) + ESTStatsSnapshot per-profile shape + ESTService.Stats(now) zero-allocation accessor + ReloadTrust() SIGHUP-equivalent + SetESTAdminMetadata setter. - Counter ticks wired into processEnrollment + SimpleServerKeygen at every success/failure leg. - internal/api/handler/admin_est.go mirrors AdminSCEPIntune verbatim: Profiles + ReloadTrust handlers + AdminESTServiceImpl. Both endpoints admin-gated (M-008 triplet pinned + admin_est.go added to AdminGatedHandlers). - New routes GET /api/v1/admin/est/profiles + POST /api/v1/admin/ est/reload-trust; openapi.yaml documented; openapi-parity guard reproduced clean. - cmd/server/main.go grows estServices map populated by the per- profile EST loop + handed to AdminEST. New MTLSTrust() + HasMTLSTrust() accessors on ESTHandler so main.go can pull the trust holder for the admin-metadata wire-up. - Per-profile counter isolation regression test (internal/service/est_profile_counter_isolation_test.go) proves a future shared-counter refactor would fail at compile-time pointer-identity check. Pre-commit verification (sandbox): gofmt clean, go vet clean (excluding repository/postgres which the sandbox can't build — disk-space testcontainers download), staticcheck clean across cms/trustanchor/api/handler/api/router/scep/intune/ratelimit/ service/pkcs7/domain/cmd/server, go test -short -count=1 green for every non-postgres package. G-3 docs-drift guard reproduced locally clean (Phases 5-7 added zero new env vars; Phase 1 already documented per-profile SERVER_KEYGEN_ENABLED). Spec preserved at cowork/est-rfc7030-hardening-prompt.md. Phases 8-13 (GUI ESTAdminPage / CLI+MCP / libest e2e / bulk revocation / docs/est.md / release prep) remain — post-2.1.0 work. |

feat(M11c): crypto policy enforcement — CSR validation, MaxTTL caps, key metadata
Enforce certificate profile crypto constraints across all 5 issuance paths (renewal, agent CSR, EST, SCEP). ValidateCSRAgainstProfile() rejects CSRs with key algorithm/size that don't match profile rules. MaxTTL enforcement caps certificate validity per issuer connector (Local CA, Vault, step-ca enforce directly; ACME/DigiCert/Sectigo pass through). Key algorithm and size are now persisted in certificate_versions for audit compliance. 16 new tests (12 service-layer + 4 Local CA connector). Removes hardcoded version number from GUI sidebar. Documentation updated across architecture, features, connectors, and README. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> |

feat(m27): certificate export (PEM/PKCS#12) and S/MIME EKU support
Add certificate export in PEM (JSON or file download) and PKCS#12 formats. Private keys are never included — they stay on agents. Add EKU-aware issuance threading profile EKUs (serverAuth, clientAuth, codeSigning, emailProtection, timeStamping) through the full issuance pipeline.

feat: add EST server (RFC 7030) for device certificate enrollment (M23)
Implement Enrollment over Secure Transport protocol with 4 endpoints under /.well-known/est/ — cacerts (CA chain distribution), simpleenroll (initial enrollment), simplereenroll (certificate renewal), and csrattrs (CSR attributes). PKCS#7 certs-only wire format with hand-rolled ASN.1, accepts both PEM and base64-encoded DER CSRs, configurable issuer and profile binding, full audit trail. 28 new tests (18 handler + 10 service). Also includes: - GetCACertPEM added to issuer connector interface (all 4 issuers updated) - EST integration tests wired into e2e test suite (13 test cases) - QA testing guide Part 26 (15 manual EST test cases) - All docs updated: README, features, architecture, concepts, connectors, quickstart, demo-advanced (endpoint counts, MCP wording, agent IDs, issuer interface, resource lists, OpenSSL status) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> |
