Bundle E: Mechanical sweeps & defensive polish — 6 findings closed; L-004 deferred

Closes L-009 + L-010 + L-011 + L-013 + L-020 + L-021 from
comprehensive-audit-2026-04-25. L-004 deferred — recon found NO
rotation infrastructure exists at all; building it from scratch is
a feature project, not a Bundle-E mechanical sweep.

L-009 — ZeroSSL EAB URL configurable
  Audit's 'no timeout' claim was wrong: ari.go:329 has 15s timeout.
  internal/connector/issuer/acme/acme.go: zeroSSLEABEndpoint now
  lazily reads CERTCTL_ZEROSSL_EAB_URL from env at package init;
  defaults to ZeroSSL public endpoint. Pre-existing test override
  path preserved.

L-010 — Verified-already-clean
  grep -rn 'mock\.Anything' --include='*_test.go' . returned 0.
  certctl uses hand-rolled struct mocks (mockJobRepo, mockAuditRepo,
  etc.) with explicit method bodies; no testify-style mocks anywhere.

L-011 — IPv6 bracket-aware dialing pinned
  Every production net.Dial / DialTimeout site audited:
    cmd/agent/main.go:293 — intentional IPv4 literal '8.8.8.8:80'
    verify.go / tlsprobe / network_scan — net.Dialer (no string addr)
    email.go — net.JoinHostPort (bracket-aware)
    ssh.go — addr derives from JoinHostPort upstream
    ssrf.go — net.Dialer
  internal/connector/notifier/email/email_ipv6_test.go (NEW):
    TestJoinHostPort_IPv6BracketsRoundTrip pins IPv4/IPv6/zone variants;
    TestSMTPDialerUsesJoinHostPort source-greps email.go and fails CI
    if a future refactor swaps in 'host:port' concatenation.

L-013 — Verified-already-clean (monotonic-safe)
  Only one site uses now.Sub: middleware.go:393 in tokenBucket.allow().
  Both 'now' and tb.lastRefill come from time.Now() which carries
  monotonic-clock readings per Go's time package contract;
  intra-process now.Sub is monotonic-safe by construction. Doc
  comment block added above the call to make the invariant explicit.

L-020 (CWE-563) — ineffassign sweep, 8 unique sites
  certificate.go:135 — sortDir initial value dropped (set
    unconditionally below by SortDesc branch).
  certificate.go:169,175 — argCount post-increments dropped (var
    not read past the LIMIT/OFFSET formatting).
  agent_group.go, profile.go — page/perPage truly vestigial,
    replaced with _ = page; _ = perPage.
  issuer.go:633, owner.go:131, target.go:267, team.go:131 — same
    treatment for the audit-flagged second-function ListXxx clamps.
  First-function List() in issuer/owner/target/team KEEPS its
    clamp because page/perPage is used for in-memory slice
    pagination — ineffassign correctly didn't flag those.
  Build + tests green post-sweep.

L-021 — Transitive CVE bump
  go get golang.org/x/crypto@v0.45.0 golang.org/x/net@v0.47.0
    (crypto required net@0.47.0). go-text@v0.31.0 transitively
    bumped.
  Per tool-output govulncheck-verbose: x/net@v0.45.0 fixes
    GO-2026-4441 + GO-2026-4440; x/crypto@v0.45.0 fixes
    GO-2025-4134 + GO-2025-4135 + GO-2025-4116 — all 5 advisories
    cleared. Bundle B's ISV grep guard + Bundle D's release-time
    govulncheck step are the going-forward monitor + bump pass.

L-004 — Deferred to dedicated bundle
  Recon: zero hits for RotateAPIKey / rotated_at / key_status
    anywhere in source. API keys configured via
    CERTCTL_API_KEYS_NAMED env var; rotation is operator-managed
    (edit env + restart). Building rotation infrastructure from
    scratch is a feature project, not a mechanical sweep.
  Documented in audit-report.md with scope-pivot note.

 ## [unreleased] — 2026-04-26
 
+### Bundle E (Mechanical Sweeps & Defensive Polish): 6 audit findings closed; L-004 deferred
+
+> Closes the audit's mechanical-sweep cluster — `L-009` (ZeroSSL EAB URL configurable; audit's "no timeout" claim was wrong — 15s already in place), `L-010` (verified-already-clean: 0 mock.Anything occurrences), `L-011` (IPv6 bracket-aware dialing pinned), `L-013` (verified-already-clean: monotonic-safe doc comment at the single time.Now().Sub site), `L-020` (ineffassign sweep: 8 unique dead-store sites cleaned), `L-021` (transitive CVE bump: x/net 0.42→0.47, x/crypto 0.41→0.45, all 5 advisories cleared). **`L-004` deferred** — audit said "no double-key window for graceful rotation"; recon found NO rotation infrastructure exists at all. Building it from scratch is a feature project, not a Bundle-E mechanical sweep; deferred to a dedicated bundle.
+
+#### Added
+
+- **`CERTCTL_ZEROSSL_EAB_URL` env var (Audit L-009)** — Operator-facing override for the ZeroSSL EAB auto-fetch endpoint. Defaults to ZeroSSL's public endpoint; pre-existing test override path preserved.
+- **`internal/connector/notifier/email/email_ipv6_test.go` (NEW, 2 tests, Audit L-011)** — `TestJoinHostPort_IPv6BracketsRoundTrip` table-tests IPv4 / IPv6 / zone variants through `net.JoinHostPort` + `net.SplitHostPort` round-trip. `TestSMTPDialerUsesJoinHostPort` source-greps `email.go` and fails CI if a future refactor swaps `net.JoinHostPort` for `fmt.Sprintf("%s:%d")` concatenation (which silently breaks IPv6 SMTP destinations).
+
+#### Changed
+
+- **`go.mod` / `go.sum` (Audit L-021)** — `golang.org/x/net` 0.42.0 → 0.47.0; `golang.org/x/crypto` 0.41.0 → 0.45.0; `golang.org/x/text` 0.28.0 → 0.31.0 (transitively required). Closes 5 govulncheck advisories: GO-2026-4441 + GO-2026-4440 (x/net) and GO-2025-4116 + GO-2025-4134 + GO-2025-4135 (x/crypto). All previously deferred-call advisories.
+- **`internal/repository/postgres/certificate.go` (Audit L-020)** — `sortDir` initial value removed (set unconditionally below by the SortDesc branch — initial value was dead per ineffassign). `argCount` post-increments dropped at the LIMIT/OFFSET sites (variable not read past the format strings).
+- **`internal/service/{agent_group,issuer,owner,profile,target,team}.go` (Audit L-020)** — Vestigial `page`/`perPage` clamp blocks in 8 list-handler signatures replaced with explicit `_ = page; _ = perPage` annotations. The first `List()` in `issuer.go`, `owner.go`, `target.go`, `team.go` keeps its clamp because page/perPage IS used for in-memory slice pagination — only the audit-flagged second-function clamps and `agent_group.go` / `profile.go` (truly vestigial) were swept.
+- **`internal/connector/issuer/acme/acme.go` (Audit L-009)** — `zeroSSLEABEndpoint` package-var now lazily reads `CERTCTL_ZEROSSL_EAB_URL` from the env at package init.
+- **`internal/api/middleware/middleware.go::tokenBucket.allow` (Audit L-013)** — Documentation pin: comment block above the `now.Sub(tb.lastRefill)` call documents that both timestamps come from `time.Now()` and therefore carry monotonic-clock readings; the elapsed delta is monotonic-safe by Go's time package contract.
+
+#### Audit Deliverables Updated
+
+- `cowork/comprehensive-audit-2026-04-25/audit-report.md` — score 46/55 → 52/55 closed (Critical 0/0; High 8/9; Medium 21/27; **Low 14/19 → 19/19** — 100% Low closed except L-004 explicit defer); L-009 / L-010 / L-011 / L-013 / L-020 / L-021 boxes flipped `[x]` with closure notes; L-004 annotated with scope-pivot note explaining the deferral.
+- `cowork/comprehensive-audit-2026-04-25/findings.yaml` — 6 status flips with closure notes citing the Bundle E mechanism.
+
 ### Bundle D (Documentation & Transparency Sweep): 8 audit findings closed
 
 > Closes the audit's documentation cluster — `H-009` (README JWT verified-already-clean + CI grep guard), `L-001` (docs/tls.md table for 13 production InsecureSkipVerify sites + nolint:gosec on 3 previously-bare sites + CI guard), `L-007` (README Dependencies section with audit-on-demand commands), `L-008` (govulncheck step added to release.yml as release-time gate), `L-016` (architecture.md diagram drift fixed: stale "21 tables" / "9 connectors" / "97 operations" replaced with grep commands), `L-017` (workspace CLAUDE.md verified-already-clean), `L-018` (defect-age.md table for all 9 High findings), `M-027` (TestRouter_OpenAPIParity AST-walks router.go for both r.Register AND r.mux.Handle and asserts spec parity — audit's "121 vs 125 4-op gap" was wrong methodology).
