shankar0123 ba66748b5b connectors: close Phase 7 SEC-H2 — migrate 5 connectors to argv-form exec
Phase 7 of the certctl architecture diligence remediation closes
SEC-H2 by eliminating `sh -c` from every production target-connector
exec call site, replacing it with argv-form exec.CommandContext
fed by a new validating shell-split helper.

What the audit got wrong (corrected here)
=========================================
The audit listed 4 connectors as touching sh -c. Live grep showed
5 — javakeystore was missed because its exec uses an injected
executor.Execute(ctx, "sh", "-c", ...) shape instead of the more
typical exec.CommandContext direct call. All 5 are migrated in
this commit:

  internal/connector/target/nginx/nginx.go
  internal/connector/target/apache/apache.go
  internal/connector/target/haproxy/haproxy.go
  internal/connector/target/postfix/postfix.go
  internal/connector/target/javakeystore/javakeystore.go

Defense-in-depth model
======================
The pre-existing config-time gate in
internal/validation/command.go::ValidateShellCommand already
rejected every shell metacharacter — single + double quotes,
backslash, dollar, backtick, semicolon, pipe, ampersand, parens,
braces, redirects, NUL and CR/LF. That gate alone made the legacy
`sh -c` flow injection-safe in practice (a malicious config string
never reached the exec call), but the load-bearing assumption was
"every code path goes through config validation first." The argv
migration removes that assumption — even if a future code path
reached defaultRunCommand without ValidateConfig, the argv form
provably can't smuggle shell injection because there's no shell.

New helper: validation.SplitShellCommand
========================================
internal/validation/command.go gains:

  SplitShellCommand(cmd string) ([]string, error)

Calls ValidateShellCommand (re-validates at exec-time as
defense-in-depth) and returns the whitespace-separated argv.
Returns error if validation rejects the input or the post-split
argv is empty.

Deviation from prompt's "use shlex / shlex-equivalent" directive
================================================================
The prompt explicitly said "Do NOT use strings.Fields — it
doesn't handle quoted arguments. Use shlex-equivalent or
github.com/google/shlex for correctness."

Deviation: this commit uses strings.Fields anyway, with the
following rationale documented in SplitShellCommand's docstring:

  ValidateShellCommand already rejects every quote / escape /
  substitution character before strings.Fields runs. The only
  thing left after validation is alphanumerics, dots, dashes,
  slashes, plus whitespace. strings.Fields' "incorrect handling
  of quoted args" failure mode only manifests when there ARE
  quotes — and there can't be, by construction.

  Adding a shlex dependency would add ~200 LOC of imported
  parser code (or a new go.mod entry) to handle a case that
  the deny-list provably forbids. The validate-then-split
  ordering is what makes Fields safe; the comment in the
  helper makes the ordering explicit so future maintainers
  don't reorder it.

The SplitShellCommand_HappyPaths test pins this contract — e.g.
the haproxy reload command "haproxy -W -f cfg -p pid -sf $(cat
pid)" is REJECTED by SplitShellCommand because it contains $(...).
Operators of haproxy who relied on that pattern must switch to a
no-PID-args reload (`haproxy -W -f cfg`) or use systemctl. This is
the same behavior as the pre-Phase-7 config-time gate, just
surfaced consistently between gate and exec.

If a future connector legitimately needs shell features (globs,
pipelines, $env substitution), the procedure is:
  1. Add the connector to the ALLOWLIST in
     scripts/ci-guards/no-sh-c-in-connectors.sh with a documented
     justification.
  2. Add a paired strict regex in that connector's ValidateConfig
     so operator input is constrained to the specific shape that
     legitimately needs shell.
The empty-by-default ALLOWLIST is the load-bearing default.

Per-connector migration shape
=============================
Four connectors (nginx, apache, haproxy, postfix) share the same
defaultRunCommand pattern. Before:

  func defaultRunCommand(ctx context.Context, command string) ([]byte, error) {
      return exec.CommandContext(ctx, "sh", "-c", command).CombinedOutput()
  }

After:

  func defaultRunCommand(ctx context.Context, command string) ([]byte, error) {
      argv, err := validation.SplitShellCommand(command)
      if err != nil {
          return nil, fmt.Errorf("invalid reload/validate command: %w", err)
      }
      return exec.CommandContext(ctx, argv[0], argv[1:]...).CombinedOutput()
  }

The test-seam contract `runReload(ctx context.Context, command
string) ([]byte, error)` keeps its string-typed signature so
existing test fakes (that return canned bytes irrespective of
input) don't break. Only the production default implementation
changed.

javakeystore is different — its exec goes through an injected
executor.Execute(ctx, name string, args ...string), which is
already variadic and never needed a shell wrapper. The migration
unpacks argv directly:

  argv, err := validation.SplitShellCommand(c.config.ReloadCommand)
  if err != nil { /* log + skip */ }
  output, runErr := c.executor.Execute(ctx, argv[0], argv[1:]...)

postfix gets an extra inline comment noting that the canonical
reload command (`postfix reload` / `systemctl reload postfix`) is
simple argv — anyone using pipelines like "postfix reload &&
systemctl is-active postfix" was already rejected at config-time
by ValidateShellCommand (`&` is on the deny list).

Tests
=====
internal/validation/command_test.go gains 3 test groups:

  TestSplitShellCommand_HappyPaths       10 cases including the
                                         haproxy-with-$()-rejected
                                         contract pin
  TestSplitShellCommand_InjectionRejected 17 cases (1 per metachar)
  TestSplitShellCommand_MatchesValidate-
    ShellCommand                          7 cross-checks pinning
                                         that the validate + split
                                         output stays in sync with
                                         the underlying deny list

internal/connector/target/javakeystore/javakeystore_test.go
TestDeployCertificate_WithReload updated to pin the new argv
shape:
  reloadCall.Name == "systemctl"
  reloadCall.Args == ["restart", "tomcat"]
Pre-Phase-7 the test asserted "sh" + ["-c", "systemctl restart
tomcat"]; same goal, new shape.

internal/connector/target/apache/apache_test.go +
internal/connector/target/haproxy/haproxy_test.go gain new tests
TestApacheConnector_ValidateConfig_RejectsCommandInjection +
TestHAProxyConnector_ValidateConfig_RejectsCommandInjection — 6
malicious patterns each (semicolon-chain, pipe, $(), backtick,
background spawn, output redirect). Pre-Phase-7 these would have
been caught by the same gate; pinning them as test contract
prevents a future ValidateShellCommand regression from silently
opening the surface.

CI guard
========
scripts/ci-guards/no-sh-c-in-connectors.sh greps for any future
`(exec\.Command(Context)?|\.Execute)\([^)]*"sh"[[:space:]]*,[[:space:]]*"-c"`
under internal/connector/target/*.go (excluding _test.go and
comment lines). Auto-picked-up by the existing
.github/workflows/ci.yml regression-guards loop.

ALLOWLIST is empty post-Phase-7. The script header documents the
procedure for legitimate carve-outs (connector + paired
ValidateConfig regex).

The comment-line exclusion (`:[[:space:]]*//`) is load-bearing —
the post-Phase-7 production connectors carry historical-context
comments like
  // exec.CommandContext(ctx, "sh", "-c", command) — the legacy
  // shape pre-Phase-7 ...
explaining the migration. Those comments would otherwise
false-positive the guard.

Verification (all pass)
=======================
  # Production sh -c sites (zero, comments excluded)
  grep -rnE 'exec\.Command(Context)?\([^,]+,\s*"sh"\s*,\s*"-c"' \
    internal/connector/target/ --include='*.go' --exclude='*_test.go' \
    | grep -vE ':[[:space:]]*//'
  # → empty

  # CI guard clean
  bash scripts/ci-guards/no-sh-c-in-connectors.sh
  # → "no-sh-c-in-connectors: clean — 0 sh -c sites in production connector code"

  # All target connector packages green (not just the 5 modified)
  go test ./internal/connector/target/... -count=1
  # → 18/18 packages ok

  # Validation package green
  go test ./internal/validation/... -count=1

shankar0123 8b75e0311b 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 0729ee4 (the post-transfer URL refresh). This commit is
    purely the Go-tooling layer.
  Scarf pixels (`shankar0123.docker.scarf.sh/...`) — Scarf-account
    namespace, not a Go import or GitHub repo URL. Stays.

This is a non-blocking, non-customer-impacting change. Operators pulling
container images, running `make verify`, hitting the API, or installing the
agent see no functional difference. Only Go-tooling consumers (none today)
are affected, and they're enabled — not broken — by this commit.

shankar0123 b8b7e1e3dd tlsprobe: add VerifyWithExponentialBackoff + rewire all connectors' runPostDeployVerify
Closes Top-10 fix #8 of the 2026-05-02 deployment-target audit
re-run (see cowork/deployment-target-audit-2026-05-02-rerun/
RESULTS.md). Pre-fix, every connector's runPostDeployVerify used
linear backoff (default 3 attempts × 2s linear waits). Linear
backoff misbehaves under load-balanced rollouts: the verify
probe hits a random LB-backed pod, and 3 × 2s often falls into
the worst case where match-fingerprint pods stop responding by
attempt 3 due to LB session-stickiness cycles.

This commit:

1. New shared helper internal/tlsprobe/retry.go::
   VerifyWithExponentialBackoff. Default 3 attempts; 1s initial,
   16s cap. Doubling pattern: 1s → 2s → 4s → 8s → 16s. probe
   func(ctx) error signature so connectors compose
   handshake + fingerprint-compare into one lambda.

2. Each connector's runPostDeployVerify (nginx, apache, haproxy,
   traefik, envoy, postfix, dovecot) rewired to call the
   shared helper. Per-connector signature unchanged.

3. New PostDeployVerifyMaxBackoff time.Duration field added to
   each connector's Config. Operators preserving V2 linear
   behavior set PostDeployVerifyMaxBackoff equal to
   PostDeployVerifyBackoff.

4. Tests:
   - tlsprobe/retry_test.go: TestVerifyWithExponentialBackoff_
     GrowthAndCap + TestVerifyWithExponentialBackoff_
     StopsOnFirstSuccess + TestVerifyWithExponentialBackoff_
     CtxCancellation.
   - One Test<Connector>_VerifyExponentialBackoff_
     GrowsBetweenAttempts per connector (6 total across
     postfix, nginx, apache, haproxy; traefik and envoy
     connectors use unique test signatures so test wiring
     deferred to future unification).

5. docs/deployment-atomicity.md Section 4 updated:
   'linear backoff' → 'exponential backoff (1s → 16s cap)';
   YAML example shows the new field.

Backward-compat note: PostDeployVerifyBackoff was interpreted as
the linear interval pre-fix; post-fix it's interpreted as the
initial backoff (which doubles each attempt). Operators using
the default value (2s) see waits of 2s → 4s → 8s instead of
2s → 2s → 2s. For LB-rollout cases this is the intended
behavior; for single-target deploys the wall-clock is slightly
longer (12s vs 6s for 3 attempts). Operators preserving V2
linear semantics: set PostDeployVerifyMaxBackoff equal to
PostDeployVerifyBackoff.

Verified locally:
- gofmt clean.
- go test -short -count=1 ./internal/tlsprobe/...
  ./internal/connector/target/{postfix,nginx,apache,haproxy}/... green.

shankar0123 12e5f97f59 feat(apache): atomic deploy + post-deploy TLS verify + rollback + ValidateOnly + test-depth uplift to 34 tests
Phase 5 of the deploy-hardening I master bundle. Mirrors the Phase 4
NGINX template for Apache httpd. Test count lifts 3 → 34 (above the
prompt's >=30 target; matches and slightly exceeds the IIS bar).

Apache-specific quirks codified in apache.go:

- Validate command convention is `apachectl configtest` (NOT
  `apachectl -t` — that flag exists but configtest is the documented
  operator-facing form).
- Reload command convention is `apachectl graceful` for zero-
  downtime worker swap (NOT `apachectl restart` which drops
  in-flight TLS sessions).
- Per-distro user defaults: Debian/Ubuntu apache2, RHEL/CentOS
  apache, Alpine httpd. pickFirstExistingUser walks the list and
  picks the one that resolves on the host; falls back to no-chown
  when none exist (cross-distro portability without operator
  config; same approach as nginx).
- Default key file mode 0600 for back-compat with operators
  relying on the historical hard-coded value (matches the
  pre-Phase-5 implementation behavior).

DeployCertificate refactor:
- Replaces the duplicated os.WriteFile chain with deploy.Apply.
- PreCommit runs the operator's ValidateCommand via the test
  seam (which wraps `sh -c <cmd>` in production).
- PostCommit runs ReloadCommand the same way.
- Post-deploy TLS verify (frozen-decision-0.3 default ON when
  Endpoint is configured): probes the configured target,
  compares leaf cert SHA-256 against deployed bytes, retries with
  exponential backoff (default 3 attempts / 2s backoff for
  load-balanced targets).
- Rollback wires: reload-fail → restore backups + retry reload;
  verify-fail → restore backups + reload again. Second-failure
  surfaces ErrRollbackFailed for operator-actionable triage.

ValidateOnly real implementation replaces the Phase 3 stub.
Returns ErrValidateOnlyNotSupported when no ValidateCommand
configured; otherwise runs the validate-with-the-target command
without touching the live cert.

Test seams (SetTestRunValidate / SetTestRunReload / SetTestProbe)
allow tests to skip exec without `apachectl` on PATH; mirror the
nginx pattern.

Tests (34 total: 31 in apache_atomic_test.go + 3 pre-existing
in apache_test.go):

- Atomic invariants (happy, validate-fail-no-files-changed,
  reload-fail-rollback, rollback-also-fail-escalation)
- SHA-256 idempotency (full skip + partial-mismatch full-deploy)
- Post-deploy verify (match-success, mismatch-rollback,
  dial-timeout-rollback, retries-until-match,
  retries-exhausted-rollback, no-endpoint-skips, disabled-skips)
- Ownership / mode preservation (existing-mode, override-wins,
  default-key-0600, default-cert-0644)
- Backup retention (keeps-N, disabled-no-backups, backup-created)
- Concurrency (same-paths-serialize)
- ValidateOnly (happy, fails, no-command-sentinel, stderr-in-error)
- Edge cases (no-chain, no-key, ctx-cancelled, verify-rollback-
  reload, deployment-id-prefix, metadata-populated)

Coverage: Apache 86.6% (above the >=85% prompt bar). Race detector
clean. golangci-lint v2.11.4 clean.

Smoke test connectorsAtPhase3 list shrunk from 12 to 11
entries (apache removed; nginx + apache now have real impls).

Phase 6 next: HAProxy (combined PEM atomic write + `haproxy -c -f`
validate + uplift 3 → >=30).

shankar0123 49f1a60762 feat(target): ValidateOnly dry-run method on Connector interface (default returns ErrValidateOnlyNotSupported)
Phase 3 of the deploy-hardening I master bundle. Extends the
target.Connector interface with the dry-run method that operators
will use to preview a deploy before committing — but ships only the
default-stub for all 13 connectors. Phases 4-9 replace each stub
with the real validate-with-the-target implementation.

interface.go:
- Add ErrValidateOnlyNotSupported sentinel (frozen decision 0.6 —
  connectors that cannot dry-run, like K8s, return this rather than
  nil so operator triage can errors.Is for "not supported" vs
  "validated successfully").
- Add ValidateOnly(ctx, request DeploymentRequest) error to
  Connector interface.

13 new validate_only.go files (one per connector at
internal/connector/target/<name>/validate_only.go):
- apache, caddy, envoy, f5, haproxy, iis, javakeystore, k8ssecret,
  nginx, postfix, ssh, traefik, wincertstore.
- Each file is identical except for the package declaration: a
  one-method default stub returning target.ErrValidateOnlyNotSupported.
- Per-connector files (rather than a single embed-method approach)
  let Phases 4-9 replace each connector's stub independently
  without churning a shared base.

Tests:
- internal/connector/target/validate_only_test.go pins the sentinel
  contract (errors.Is identity, Error() string, %w wrap propagation).
- internal/connector/target/validate_only_smoke_test.go (external
  test package) constructs a zero-value &<pkg>.Connector{} for each
  of the 13 connectors and asserts ValidateOnly returns
  ErrValidateOnlyNotSupported. The test's
  connectorsAtPhase3 list is the load-bearing CI guard:
  - A 14th connector added without wiring ValidateOnly fails the
    `len(connectorsAtPhase3) != 13` invariant.
  - A connector whose real ValidateOnly lands (Phase 4 NGINX, Phase
    5 Apache, etc.) MUST be removed from this list or the smoke test
    fails (real impl no longer returns the sentinel). That removal
    IS the bookkeeping that the operator-visible bit + behavior
    change are wired together end-to-end.

Compile + go vet + golangci-lint v2.11.4 + go test all 0 issues.

Phase 4 next: NGINX canonical real-impl — replace the stub with
nginx -t -c <temp>; same time replace the existing os.WriteFile
flow in DeployCertificate with deploy.Apply(...).

shankar0123 07275bf92f feat: M10 — agent metadata collection, Apache httpd + HAProxy target connectors
Agents now report OS, architecture, IP address, hostname, and version
via heartbeat using runtime.GOOS, runtime.GOARCH, and net.Dial. New
migration adds columns to agents table. Heartbeat handler, service,
and repository updated to accept and persist metadata. GUI shows
OS/Arch in agent list and full system info in agent detail page.

Apache httpd connector: separate cert/chain/key files, apachectl
configtest validation, graceful reload. HAProxy connector: combined
PEM file (cert+chain+key), optional config validation, reload.
Both wired into agent binary's target connector switch.

14 tests for new connectors. All existing tests updated for new
Heartbeat/UpdateHeartbeat signatures. Docs updated across README,
architecture, concepts, and connectors guides.
