shankar0123 67fadeb4e6 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.

shankar0123 8bc9f4eed8 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.

certctl-copilot 28797b1cbb feat(scep): plumb CertificateProfile.MustStaple end-to-end through service layer 
SCEP RFC 8894 + Intune master bundle Phase 5.6 follow-up.

Closes the 'lying field' gap from the original Phase 5.6 commit (35fcfa7).
That commit shipped CertificateProfile.MustStaple as a domain field +
IssuanceRequest.MustStaple as the issuer-interface field + the local
issuer's RFC 7633 extension generation + byte-exact tests against the
spec — but the service layer (SCEP + EST + agent + renewal) never read
profile.MustStaple and never set IssuanceRequest.MustStaple. Operators
who set the field got: a stored value, an API that returned it, docs
that promised it worked, and a cert with no extension. Worse than not
having the field at all.

Per the new operating rule landed in cowork/CLAUDE.md::Operating Rules
('Always take the complete path, not the easy path'), this commit closes
the wire end-to-end.

internal/service/renewal.go
  * IssuerConnector interface signature gains a mustStaple bool param on
    IssueCertificate + RenewCertificate. The original 'this is a wider
    refactor' framing was overstated — it's one extra arg threaded
    through six call sites, not a structural change.

internal/service/issuer_adapter.go
  * IssuerConnectorAdapter.IssueCertificate + RenewCertificate accept
    the new param + populate IssuanceRequest.MustStaple /
    RenewalRequest.MustStaple. Connectors that don't honor extension
    injection (Vault, EJBCA, ACME, etc.) silently ignore the field —
    the Phase 5.6 commit's docblock already noted this.

internal/service/scep.go
  * processEnrollment now reads profile.MustStaple alongside
    profile.MaxTTLSeconds and threads it through the IssueCertificate
    call. The SCEP path was the load-bearing one — the original Phase
    5.6 docs example showed exactly this code shape but the wire was
    never landed.

internal/service/est.go
  * Same pattern as SCEP: read profile.MustStaple + thread to
    IssueCertificate. Defense in depth so a deploy that mounts the
    same profile across SCEP + EST gets consistent extension behavior.

internal/service/agent.go
  * The fallback direct-issuer signing path in heartbeatPipeline reads
    profile + threads MustStaple through. Server-mode keygen + ad-hoc
    CSR submission paths both go through this.

internal/service/renewal.go (the renewal-loop side, not the interface)
  * Both renewal call sites (server-CSR-generated + agent-CSR-submitted)
    read profile.MustStaple + thread it through RenewCertificate. Renewed
    certs match their initial-issuance extension set when the bound
    profile changes mid-lifetime.

internal/service/scep_must_staple_test.go (new)
  * TestSCEPService_PKCSReq_PlumbsMustStapleToIssuer — end-to-end
    integration test: profile.MustStaple=true → SCEP service →
    mock IssuerConnector saw mustStaple=true. This is the test the
    original Phase 5.6 commit should have shipped — proves the wire
    reaches the connector.
  * TestSCEPService_PKCSReq_NoMustStaplePropagatesFalse — companion
    pinning the symmetric contract; the mock pre-sets LastMustStaple=true
    so a stuck-at-true bug surfaces.

internal/service/testutil_test.go +
internal/service/m11c_crypto_enforcement_test.go +
internal/service/issuer_adapter_test.go +
cmd/server/preflight_test.go
  * Mock + fake IssuerConnector implementations gain the new mustStaple
    bool param. mockIssuerConnector + capturingIssuerConnector also gain
    a LastMustStaple / lastMustStaple field used by the new integration
    tests to assert the wire reached the connector.
  * Existing test call sites for adapter.IssueCertificate /
    adapter.RenewCertificate gain a trailing 'false' arg (mechanical bulk
    edit, no behavior change).

Verification:
  * gofmt + go vet + staticcheck clean for all touched paths.
  * go test -short -count=1 green across cmd/agent / cmd/cli /
    cmd/mcp-server / cmd/server / api/handler / api/middleware /
    api/router / service / scheduler / pkcs7 / connector/issuer/local /
    every connector subpackage / domain / crypto / mcp / repository.
  * The new TestSCEPService_PKCSReq_PlumbsMustStapleToIssuer test passes,
    proving the wire works end-to-end.

The follow-up rule from cowork/CLAUDE.md::Operating Rules — 'can an
operator flip the configurable bit and observe the behavior change
end-to-end with no further code changes?' — is now YES for must-staple
on the SCEP + EST + agent + renewal paths.

Shankar ff223e2586 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.

Shankar c014c17cc6 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. Fix
agent CSR SAN splitting for email addresses, adaptive KeyUsage flags for
S/MIME vs TLS, and a pre-existing generateID collision bug in deployment
job creation.

Shankar e4ba8d4de2 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)
