docs(acme-server): operator-facing reference + threat model + cert-manager walkthrough (Phase 6/7)
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.

acme-server: cert-manager integration test + production hardening (Phase 5/7)
Closes the production-readiness loop on the ACME surface. After this
commit, certctl ships per-account rate limits + a GC sweeper for
expired ACME state + a kind-driven cert-manager 1.15 integration test
+ a lego-driven RFC conformance harness + a k6 loadtest scenario for
the unauthenticated ACME path.
Architecture:
- Rate limits live in-memory + per-replica. Restart wipes the
counters; orders/hour caps are eventual-consistency anyway. A
3-replica certctl-server fleet behind an LB effectively has 3x
the configured throughput per account; persistent rate limiting
is a follow-up if production telemetry shows abuse patterns we
can't catch in a single restart cycle. Per-key + per-action
isolation: ActionNewOrder/acc-1, ActionKeyChange/acc-1, and
ActionChallengeRespond/<challenge-id> are independent buckets.
- GC loop follows the existing scheduler-loop pattern (atomic.Bool
+ sync.WaitGroup; see crlGenerationLoop for shape). Three
independent SQL sweeps per tick (DELETE expired nonces; UPDATE
pending authzs whose expires_at < now() to expired; UPDATE
pending/ready/processing orders whose expires_at < now() to
invalid). Each sweep is a single statement; failures are logged-
and-continued so a failing nonces sweep doesn't block authzs.
Per-sweep 1m timeout bounds a stuck Postgres.
- cert-manager integration test is gated on KIND_AVAILABLE so CI
skips it cleanly (kind is too heavy for per-PR). Operators run
locally via 'make acme-cert-manager-test'; the harness brings up
a fresh cluster each run + tears it down on Cleanup.
- lego conformance harness drives a real ACME client through
register → run → cert-PEM-landed against a hermetic certctl
stack. Catches RFC-shape regressions third-party clients would
hit before they ship.
- k6 ACME-flow scenario hammers the unauthenticated surface
(directory + new-nonce + ARI synthetic-id) at 100 VUs × 5m. JWS-
signed flows are out of scope for k6 (no JWS support); they're
covered by the lego harness above.
What ships:
- internal/api/acme/ratelimit.go (+ ratelimit_test.go: 7 cases —
disable-when-perHour-zero, capacity, per-key isolation, per-
action isolation, refill-over-time, RetryAfter, concurrent-access
with -race + 200 goroutines × 200 calls).
- internal/repository/postgres/acme.go: 4 new methods —
CountActiveOrdersByAccount + GCExpiredNonces + GCExpireAuthorizations
+ GCInvalidateExpiredOrders. Each a single SQL statement.
- internal/service/acme.go: SetRateLimiter + GarbageCollect +
rate-limit gates at 3 entry points (CreateOrder + RotateAccountKey
+ RespondToChallenge) + concurrent-orders gate at CreateOrder.
2 new sentinels (ErrACMERateLimited, ErrACMEConcurrentOrdersExceeded);
5 new GC metrics (gc_runs / gc_run_failures / gc_nonces_reaped /
gc_authzs_expired / gc_orders_invalidated).
- internal/scheduler/scheduler.go: ACMEGarbageCollector interface +
acmeGCRunning atomic.Bool + acmeGCInterval + 2 setters (SetACME-
GarbageCollector + SetACMEGCInterval) + acmeGCLoop following the
crlGenerationLoop shape.
- internal/api/handler/acme.go: writeServiceError gains rateLimited
(429 + RFC 8555 §6.7) + concurrent-orders-exceeded mappings.
- internal/config/config.go: 5 new env vars
(CERTCTL_ACME_SERVER_RATE_LIMIT_ORDERS_PER_HOUR=100,
CERTCTL_ACME_SERVER_RATE_LIMIT_CONCURRENT_ORDERS=5,
CERTCTL_ACME_SERVER_RATE_LIMIT_KEY_CHANGE_PER_HOUR=5,
CERTCTL_ACME_SERVER_RATE_LIMIT_CHALLENGE_RESPONDS_PER_HOUR=60,
CERTCTL_ACME_SERVER_GC_INTERVAL=1m).
- cmd/server/main.go: NewRateLimiter() + SetRateLimiter() at
startup; conditional SetACMEGarbageCollector(acmeService) +
SetACMEGCInterval(cfg.ACMEServer.GCInterval) when Enabled+
GCInterval > 0.
- deploy/test/acme-integration/: kind-config.yaml + cert-manager-
install.sh + clusterissuer-trust-authenticated.yaml +
clusterissuer-challenge.yaml + certificate-test.yaml + conformance-
lego.sh + certmanager_test.go (//go:build integration + KIND_AVAILABLE
gate).
- deploy/test/loadtest/k6/acme_flow.js + README ACME-flows section.
- Makefile: 2 new PHONY targets (acme-cert-manager-test +
acme-rfc-conformance-test).
- docs/acme-server.md: status flipped to Phase 5; Configuration
table grows 5 rows; new 'Phase 5 — operational guidance' section
explaining rate-limit math + GC sweeper semantics + cert-manager
integration + lego conformance + k6 baseline.
Tests:
- 'go vet ./...' clean across the repo.
- 'go test -short -count=1 ./internal/...' green across every
affected package (service / acme / handler / scheduler / repo /
config).
- 'go vet -tags=integration ./deploy/test/acme-integration/' clean
(the integration test compiles cleanly with the build tag).
- The kind/cert-manager harness is gated behind KIND_AVAILABLE so
CI skips by default; operators run locally via 'make acme-cert-
manager-test'.

acme-server: key rollover + revocation + ARI (Phase 4/7)
Closes the RFC 8555 + RFC 9773 surface beyond the issuance happy-path:
- POST /acme/profile/<id>/key-change (RFC 8555 §7.3.5)
- POST /acme/profile/<id>/revoke-cert (RFC 8555 §7.6)
- GET /acme/profile/<id>/renewal-info/<cert-id> (RFC 9773 ARI)
After this commit, ACME clients can rotate account keys, revoke certs
through the ACME surface (rather than only via the certctl GUI/API),
and fetch ARI for proactive renewal scheduling.
Architecture:
- Key rollover: outer JWS verified against the registered account key
(existing kid path); the inner JWS — embedded as the outer's payload
— verified against the embedded NEW jwk in a new dedicated routine
(ParseAndVerifyKeyChangeInner) that enforces RFC 8555 §7.3.5
inner-only invariants: MUST use jwk + MUST NOT use kid, payload
.account == outer.kid, payload.oldKey thumbprint-equals registered.
A single WithinTx swaps the stored thumbprint+pem and writes the
audit row. Concurrent-rollover safety via SELECT…FOR UPDATE on the
conflicting account row in UpdateAccountJWKWithTx; the loser
observes the winner's new thumbprint and is told to retry (409).
- Revocation: two auth paths. kid → AccountOwnsCertificate single-
indexed COUNT lookup over acme_orders. jwk → constant-time RFC 7638
thumbprint compare against the cert's pubkey. Both paths route
through service.RevocationSvc.RevokeCertificateWithActor so the
existing CRL/OCSP refresh + audit + metrics pipeline applies. RFC
5280 §5.3.1 numeric reason codes clamp to certctl's
domain.ValidRevocationReasons; codes 8 (removeFromCRL) + 10
(aACompromise) clamp to 'unspecified' since they aren't in the set.
- ARI is GET-only and unauth per RFC 9773 §4. Cert-id wire shape is
base64url(AKI).base64url(serial); ParseARICertID strict-decodes,
SerialHex emits the canonical certctl-shape lowercase-no-leading-
zeros hex used in certificate_versions.serial_number.
ComputeRenewalWindow has 3 branches: bound RenewalPolicy →
[notAfter - days, notAfter - days/2]; no policy → last 33% of
validity; past expiry → [now, now + 1d] (renew immediately).
Retry-After honors CERTCTL_ACME_SERVER_ARI_POLL_INTERVAL.
What ships:
- internal/api/acme/{keychange,ari}.go (+ phase4_test.go: 15 tests).
- internal/api/acme/order.go: RevokeCertRequest wire shape.
- internal/api/handler/acme.go: KeyChange, RevokeCert, RenewalInfo
+ 11 new writeServiceError mappings.
- internal/repository/postgres/acme.go: UpdateAccountJWKWithTx (FOR
UPDATE + expectedOldThumbprint precondition; ErrACMEAccountKey-
ConcurrentUpdate sentinel) + AccountOwnsCertificate.
- internal/service/acme.go: RotateAccountKey + RevokeCert +
RenewalInfo; CertificateRevoker + RenewalPolicyLookup interfaces;
SetRevocationDelegate + SetRenewalPolicyLookup wiring; 11 new
sentinels; 6 new metrics.
- internal/service/acme_phase4_test.go: service-layer tests for
RotateAccountKey (happy + duplicate-key) + RevokeCert (kid mismatch
+ jwk mismatch + jwk happy + already-revoked + reason-clamping) +
RenewalInfo (disabled + bad cert-id).
- internal/api/router/router.go: 6 new register calls (3 per-profile
+ 3 shorthand). Router parity exceptions extended in lockstep
(in-tree SpecParityExceptions + CI-only openapi-handler-exceptions
.yaml).
- cmd/server/main.go: SetRevocationDelegate(revocationSvc) +
SetRenewalPolicyLookup(renewalPolicyRepo) at startup.
- internal/config/config.go: CERTCTL_ACME_SERVER_ARI_ENABLED (default
true) + CERTCTL_ACME_SERVER_ARI_POLL_INTERVAL (default 6h);
BuildDirectory's ariEnabled flag now flips on under
cfg.ARIEnabled.
- docs/acme-server.md: phase status flipped to Phase 4; endpoints
table grows 6 rows (3 per-profile + 3 shorthand); FAQ section
appended explaining how to rotate keys, revoke certs, and consume
ARI.
Tests:
- 'go vet ./...' clean across the repo.
- 'go test -short -count=1 ./...' green across every package.
- phase4_test.go covers: keychange happy-path + 5 negatives +
MapKeyChangeErrorToProblem coverage; ARI cert-id round-trip + 6
malformed cases + BuildARICertID from a generated cert; window-
math 3 branches.
- service-layer tests confirm: RotateAccountKey atomically swaps the
thumbprint (verifies persisted state) and rejects duplicate keys;
RevokeCert routes through the stub RevocationSvc with the right
actor string + reason on the jwk path, rejects mismatched keys,
rejects already-revoked certs, clamps reason codes correctly;
RenewalInfo respects ARIEnabled + cert-id format.

acme-server: HTTP-01 + DNS-01 + TLS-ALPN-01 challenge validation (Phase 3/7)
Wires up the actual challenge-validation machinery so profiles in
acme_auth_mode='challenge' resolve end-to-end. After this commit,
cert-manager 1.15+ with `solver: http01: ingress` against a
challenge-mode profile completes a real HTTP-01 flow and gets a cert.
DNS-01 + TLS-ALPN-01 share the same code path with the appropriate
validator selection.
Architecture (the load-bearing parts):
- 3 separate semaphore-bounded worker pools (one per challenge type),
so HTTP-01 and DNS-01 can't starve each other under load. Default
weight 10 per type; tunable via CERTCTL_ACME_SERVER_HTTP01_CONCURRENCY,
DNS01_CONCURRENCY, TLSALPN01_CONCURRENCY.
- 30s per-challenge timeout (configurable via PoolConfig.PerChallengeTimeout).
- HTTP-01 validator runs validation.IsReservedIPForDial (newly
exported wrapper preserving the existing private impl byte-for-byte
for the network scanner + ValidateSafeURL paths) on the resolved
IP — both at the initial dial and every redirect hop. SSRF probes
into private IP space are refused before the connect.
- DNS-01 validator uses a dedicated resolver pointed at
CERTCTL_ACME_SERVER_DNS01_RESOLVER (default 8.8.8.8:53) — does
NOT use the system resolver to keep behavior deterministic across
deployments. Wildcard handling: `*.example.com` queries
_acme-challenge.example.com.
- TLS-ALPN-01 validator (RFC 8737) connects with ALPN `acme-tls/1`,
inspects the id-pe-acmeIdentifier extension (OID 1.3.6.1.5.5.7.1.31),
asserts the ASN.1 OCTET STRING value equals SHA-256 of the key
authorization. Cert chain is intentionally NOT validated
(InsecureSkipVerify=true is correct per RFC 8737 — the proof is
in the extension, not the chain). Documented in docs/tls.md L-001
table + the //nolint:gosec comment carries the justification.
SSRF guard: same posture as HTTP-01.
- Validation is asynchronous: handler accepts the POST and returns
200 immediately with status=processing; the worker-pool fires a
callback that updates challenge → authz → order in a fresh
background-context WithinTx. The order auto-promotes to `ready`
when ALL authzs become valid; auto-fails to `invalid` when ANY
authz becomes invalid.
What ships:
- internal/api/acme/challenge.go: KeyAuthorization (RFC 8555 §8.1) +
DNS01TXTRecordValue (§8.4) + TLSALPN01ExtensionValue (RFC 8737 §3)
helpers; IDPEAcmeIdentifierOID; ChallengeProblemFromError mapper
(4-way: connection / dns / tls / incorrectResponse); 9 sentinel
errors covering every named failure mode.
- internal/api/acme/validators.go: ChallengeValidator interface;
Pool dispatcher with 3 semaphores + per-type in-flight + peak
gauges; HTTP01Validator + DNS01Validator + TLSALPN01Validator
implementations; Drain method called from cmd/server/main.go's
shutdown sequence.
- internal/api/acme/validators_test.go: KeyAuthorization round-trip,
DNS01 / TLS-ALPN-01 helper tests, SSRF rejection, bounded-
concurrency saturation test (peak-in-flight ≤ cap), type-isolation
test (HTTP-01 saturation doesn't block DNS-01), UnknownType test,
7-case ChallengeProblemFromError mapping.
- internal/repository/postgres/acme.go: GetChallengeByID +
UpdateChallengeWithTx + UpdateAuthzStatusWithTx.
- internal/service/acme.go: SetValidatorPool wires the *acme.Pool;
RespondToChallenge dispatches with account-ownership assertion +
KeyAuthorization computation + processing-status transition (atomic
+ audit); recordChallengeOutcome callback persists the final
challenge + cascading authz + order-promote/-fail in one WithinTx +
audit row. 4 new metrics.
- internal/api/handler/acme.go: Challenge handler; round-trips
account.JWKPEM through ParseJWKFromPEM to recover the *jose.JSONWebKey
the validator pool needs.
- internal/api/router/router.go + openapi_parity_test.go +
api/openapi-handler-exceptions.yaml: 2 new routes (per-profile +
shorthand for challenge/{chall_id}) with parity exceptions.
- cmd/server/main.go: constructs the Pool at startup with the
per-type concurrency caps from cfg.ACMEServer; ACMEService.ValidatorPool()
accessor exposed for the shutdown drain sequence.
- internal/validation/ssrf.go: exported IsReservedIPForDial wrapper
(private impl unchanged; network scanner + ValidateSafeURL paths
byte-identical with prior behavior).
- docs/tls.md: L-001 InsecureSkipVerify table extended with the
TLS-ALPN-01 validator justification (RFC 8737 §3).
- docs/acme-server.md: phase status updated; endpoints table grows
the challenge row; phases-cross-reference flips Phase 3 → live.
Tests:
- 80%+ coverage on the new files.
- BoundedConcurrency test: 10 challenges submitted against an
HTTP-01 pool of weight 3; observed peak-in-flight ≤ 3, all 10
eventually complete, post-Drain in-flight returns to 0.
- TypeIsolation test: HTTP-01 saturation does NOT block a DNS-01
submission; DNS-01 callback fires within 2s.
- SSRF rejection test: a Validate against `localhost` is refused
before the dial (ErrChallengeReservedIP or ErrChallengeConnection).

acme-server: foundation — directory + new-nonce + per-profile routing (Phase 1a/7)
First slice of the RFC 8555 ACME server endpoint (master plan at cowork/acme-server-endpoint-prompt.md, per-phase prompts at cowork/acme-server-prompts/). This commit lands the smallest viable end-to-end deployable slice: an ACME client running curl -sk https://certctl/acme/profile/<id>/directory curl -sk -I https://certctl/acme/profile/<id>/new-nonce successfully fetches the directory document and a Replay-Nonce. Account creation, JWS verification, orders, challenges, and revocation are all out of scope for this phase and arrive in Phases 1b–4. Closes the Rank 1 LHF from the 2026-05-03 Infisical deep-research (cowork/infisical-deep-research-results.md). Pre-fix, certctl was an ACME consumer only — no /acme/directory endpoint, no JWS verifier, no challenge validators. K8s customers running cert-manager could not point at certctl as an ACME issuer; they had to deploy a certctl agent on every node. What ships: - internal/api/acme/{directory,nonce,errors}.go (+ tests). - internal/api/handler/acme.go + acme_handler_test.go. - internal/repository/postgres/acme.go (nonce ops only — Phase 1b extends with account CRUD; Phases 2-4 extend with order / authz / challenge CRUD). - internal/service/acme.go (BuildDirectory + IssueNonce stubs; Phase 1b adds VerifyJWS / NewAccount / etc.). - migrations/000025_acme_server.{up,down}.sql ships the full 5-table ACME schema (acme_accounts / acme_orders / acme_authorizations / acme_challenges / acme_nonces) PLUS the per-profile certificate_profiles.acme_auth_mode column. Phase 1a actively uses only acme_nonces; remaining tables are empty until Phases 1b-4 plug in. - internal/config/config.go: ACMEServerConfig struct + ACMEServer field on Config. Env vars use CERTCTL_ACME_SERVER_* prefix to avoid colliding with the existing consumer-side ACMEConfig at config.go:1746 (CERTCTL_ACME_DIRECTORY_URL / PROFILE / CHALLENGE_TYPE etc.). Phase 1a wires Enabled + DefaultAuthMode + DefaultProfileID + NonceTTL + DirectoryMeta; Order/Authz TTLs + per-challenge-type concurrency caps + DNS01 resolver are reserved fields parsed in 1a so operators can set them ahead of Phases 2/3. - cmd/server/main.go: wire ACMEHandler into the HandlerRegistry literal alongside the existing certificate / EST / SCEP / etc. handlers. - internal/api/router/router.go: HandlerRegistry.ACME field + 6 Register calls (3 per-profile + 3 shorthand). - internal/api/router/openapi_parity_test.go: 6 new entries in SpecParityExceptions. ACME is a wire-protocol surface (JWS-signed JSON over HTTPS per RFC 7515) whose semantics are dictated by RFC 8555 + RFC 9773 rather than by an OpenAPI document, same precedent as SCEP/EST. The canonical reference is docs/acme-server.md. - docs/acme-server.md: Phase-1a-shaped reference. Configuration table for every CERTCTL_ACME_SERVER_* env var. Per-profile auth-mode decision tree skeleton. TLS trust bootstrap section flagging cert-manager's ClusterIssuer.spec.acme.caBundle requirement (the single biggest first-time-deploy footgun; the full cert-manager walkthrough lands in Phase 6 but the requirement is documented up front). Architecture decisions baked in: - URL family is /acme/profile/<id>/* (per-profile, canonical) with /acme/* shorthand active when CERTCTL_ACME_SERVER_DEFAULT_PROFILE_ID is set. Path matches existing per-profile precedent in EST + SCEP. - Auth mode is per-profile (acme_auth_mode column on certificate_profiles), NOT server-wide. One certctl-server can serve trust_authenticated for an internal-PKI profile and challenge for a public-trust-style profile simultaneously. The column is read at request time, not cached at server start — operators flipping a profile's mode via SQL take effect on the next order without restart. - Nonces are DB-backed (acme_nonces table). Survive server restart. The RFC 8555 §6.5 replay defense requires the store to outlast the client's nonce caching window; an in-memory-only nonce store would lose every in-flight order on restart. - Per-op atomic counters on service.ACMEService.Metrics() — certctl_acme_directory_total, certctl_acme_directory_failures_total, certctl_acme_new_nonce_total, certctl_acme_new_nonce_failures_total. Naming follows certctl frozen decision 0.10 cardinality discipline. Phase 1b will extend with new_account counters; Phase 2 with order / finalize / cert; Phase 3 with per-challenge-type counters. Audit fixes #11 + #12 (cowork/acme-server-prompts/audit-additions.md) applied: - #11: CERTCTL_ACME_SERVER_* prefix avoids the consumer-side CERTCTL_ACME_* namespace collision. - #12: prior-attempt WIP from two failed Phase-1 dispatches was discarded at phase start; this commit starts from a clean tree. Tests: - 14 unit tests in internal/api/acme/ (directory, nonce, errors). - 7 handler-level tests via httptest.NewServer + mockACMEService (mirrors the mockSCEPService pattern at scep_handler_test.go). - 7 service-layer tests with mocked repo + injected profileLookup. - All pass under -race -count=1 -short. Deferred to Phase 1b: - JWS verification (go-jose v4 — see master-prompt §8a for the API surface and audit doc for the speculation pitfalls). - new-account / account/<id> endpoints + AccountService. - Nonce *consumption* path (issue path is in this commit; consume is only invoked by JWS-verified POSTs which Phase 1b adds).
