shankar0123 21aeed4f4e 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.

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 08a86d355d caddy: fix duration metric + file-mode PEM validate + api-mode idempotency
Closes Bundle 9 of the 2026-05-02 deployment-target coverage audit
(see cowork/deployment-target-audit-2026-05-02/RESULTS.md). Three
small independent fixes that share one connector file:

1. Duration metric (caddy.go L176). Pre-fix:
     "duration_ms": fmt.Sprintf("%d", time.Since(time.Now()).Milliseconds())
   This always returned ~0ms because time.Now() was called twice —
   the second call captured a baseline immediately before time.Since
   computed the delta. The intended baseline is `startTime` declared
   at L113 and threaded through deployViaFile correctly. Post-fix:
     "duration_ms": fmt.Sprintf("%d", time.Since(startTime).Milliseconds())
   deployViaAPI's signature evolves to take startTime time.Time so
   the api-mode path uses the same baseline as the file-mode path.

2. File-mode ValidateDeployment now validates PEM syntax. Pre-fix
   (caddy.go L266-293) checked file existence only via os.Stat. A
   cert file containing garbage bytes passed validation; Caddy's
   file-watcher silently failed to load it; operators saw "validation
   green" + "TLS handshake fails" with no obvious connection.
   Post-fix: after the os.Stat checks succeed, os.ReadFile + parse
   the first PEM block as an x509 cert via the shared
   certutil.ParseCertificatePEM helper. Failure surfaces as
   Valid=false with a clear "not valid PEM/x509" message.

3. API-mode idempotency short-circuit. Pre-fix, every deploy POSTed
   to /config/apps/tls/certificates/load even when the active cert
   was already what we wanted to deploy. Caddy reloads TLS state on
   every POST, briefly bumping CPU and possibly disrupting connections
   in flight. Post-fix: idempotencySkipPOST runs a GET first, parses
   the response (handles BOTH the array-of-objects and single-object
   shapes Caddy admin can return), SHA-256 compares the entry's
   `cert` field to the deploy payload's cert bytes, and skips the
   POST when match. Result.Metadata["idempotent"]="true" surfaces
   the no-op. Conservative: any GET failure (network, non-200, parse
   error, no matching entry, hash mismatch) silently falls through to
   the POST, preserving today's behavior. Idempotency is a fast path,
   not a correctness boundary — false negatives are safe; false
   positives are dangerous.

Tests added to caddy_test.go (6 new tests, ~290 LOC):
- TestCaddy_API_DurationMetric_NonZero (httptest server with a 10ms
  sleep in the POST handler; asserts duration_ms parses as int >= 5).
- TestCaddy_ValidateDeployment_FileMode_MalformedPEM_Rejected (writes
  garbage to cert.pem; asserts Valid=false with PEM/x509 in message).
- TestCaddy_ValidateDeployment_FileMode_ValidPEM_Accepted (writes a
  real ECDSA P-256 self-signed cert; asserts Valid=true).
- TestCaddy_API_Idempotent_SkipsPOSTWhenCertHashMatches (GET response
  contains the same cert as the deploy payload; POST counter remains
  0; metadata.idempotent=true; exactly 1 GET probe ran).
- TestCaddy_API_Idempotent_RunsPOSTWhenCertHashDiffers (GET response
  contains a DIFFERENT cert; POST counter is 1; idempotent absent).
- TestCaddy_API_Idempotent_GETFails_FallsThroughToPOST (GET returns
  500; POST still runs; deploy succeeds; idempotent absent).

Two existing tests updated to match the new contracts:
- TestCaddyConnector_DeployViaAPI_Success: mock handler now serves
  BOTH GET (returns "[]" so the comparison falls through) and POST
  (the original 200-OK path). The dispatch is a method-switch
  inside the path-match branch.
- TestCaddyConnector_ValidateDeployment_Success: the placeholder
  cert "MIIC..." used to pass the old existence-only check; post-Fix-2
  it fails the PEM-parse check. Test now uses generateTestCertAndKey
  to produce a real self-signed ECDSA P-256 cert.

generateTestCertAndKey helper added to the test file — same pattern
the javakeystore + wincertstore tests use, kept local because the
caddy package has no other test in the certutil family that would
make a shared helper cleaner.

Verified locally:
- gofmt -l ./internal/connector/target/caddy/  clean
- go vet ./internal/connector/target/caddy/  clean
- go build ./cmd/agent/...  clean (factory wiring unchanged)
- go test -race -count=1 ./internal/connector/target/caddy/  green
  (16 tests total: 11 pre-existing including the two updated +
  6 new)

shankar0123 a7cce9afdd feat(traefik,caddy,envoy,postfix): atomic deploy + post-deploy TLS verify + rollback + ValidateOnly
Phase 7 of the deploy-hardening I master bundle. Retrofits the
remaining file-based connectors against the canonical NGINX template.
Per-connector quirks codified:

- Postfix/Dovecot: full retrofit with PreCommit (postfix check /
  doveconf -n) + PostCommit (postfix reload / doveadm reload) +
  post-deploy TLS verify. Quirk preserved: when ChainPath is empty,
  chain is appended to cert (Postfix/Dovecot's "no separate chain"
  mode). Per-distro user defaults: postfix, dovecot, _postfix.
  Default key mode 0600. ValidateOnly real impl returns sentinel
  when no ValidateCommand.

- Traefik: simpler retrofit — no PreCommit/PostCommit because
  Traefik watches the cert directory via inotify and auto-reloads.
  Atomic-write via deploy.AtomicWriteFile + post-deploy TLS verify
  + cert rollback on verify mismatch. Default key mode 0600.
  ValidateOnly returns sentinel (no validate-with-the-target
  command exists for Traefik).

- Caddy: retrofitted both modes. File mode replaces os.WriteFile
  with deploy.AtomicWriteFile (preserves the file watcher's auto-
  reload). API mode unchanged (POST /load already atomic at the
  Caddy admin server). ValidateOnly real impl: API mode probes
  the admin /config/ endpoint to confirm Caddy is reachable;
  file mode returns sentinel.

- Envoy: file mode atomic-write via deploy.AtomicWriteFile.
  Envoy's SDS file watcher picks up the rename atomically without
  config reload. ValidateOnly returns sentinel (no Envoy CLI
  validate command exists for individual cert files).

Test counts (all packages above the prompt's >=20 bar):
- Postfix: 30 (12 new in postfix_atomic_test.go + 18 pre-existing)
- Traefik: 22 (12 new in traefik_atomic_test.go + 10 pre-existing)
- Caddy: 22 (10 new in caddy_atomic_test.go + 12 pre-existing)
- Envoy: 21 (5 new in envoy_atomic_test.go + 16 pre-existing)

Coverage: each connector at the prompt's >=80% target. golangci-lint
v2.11.4 clean across all 4 connector packages.

Smoke test connectorsAtPhase3 list shrunk from 10 to 6 entries
(postfix removed alongside nginx + apache + haproxy; traefik /
caddy / envoy retain their stubs in the list because their
ValidateOnly returns the sentinel for V2 — the real implementation
arrives only when there's a meaningful validate-with-the-target
command).

Wait — actually the smoke test still pins all 4 because their
ValidateOnly returns the sentinel. Postfix's real impl returns nil
on success (when ValidateCommand is set), so postfix MUST be
removed. Caddy's API mode is real-impl. Traefik + Envoy still
return sentinel always — they stay in the smoke list.

Phase 8 next: F5 + IIS — explicit post-deploy TLS verify +
on-failure rollback. Both already have transactional semantics
internally; the Phase 8 work is making rollback explicit + adding
the post-deploy verify.

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 be72627aeb feat: M25 post-deployment TLS verification + M26 Traefik/Caddy targets
M25: After deploying a certificate, the agent probes the live TLS
endpoint and compares SHA-256 fingerprints to verify the correct cert
is being served. Best-effort — failures don't block deployments.
New endpoints: POST /jobs/{id}/verify, GET /jobs/{id}/verification.
Migration 000008 adds verification columns to jobs table.

M26: Traefik target connector (file provider, auto-reload) and Caddy
target connector (dual-mode: admin API hot-reload or file-based).
Both wired into agent dispatch.

Also: restructured README to highlight supported integrations (issuers,
targets, notifiers) earlier, moved API/CLI/MCP sections lower. Updated
all docs (features, connectors, architecture, testing guide, why-certctl)
and fixed integration tests for 18-param RegisterHandlers signature.
