…ket retrieval (#219)

## Summary

Add automatic leak detection and redaction to `opct retrieve`, and
replace the deprecated SPDY protocol with WebSocket for archive
retrieval.

Fixes: OPCT-423

## Key Changes

### 1. Leak Detection & Redaction (redact-by-default)

Sensitive data in archives is automatically redacted with
`<REDACTED_BY_OPCT>`:
- 12 curated patterns from
[leaktk/patterns](https://github.com/leaktk/patterns) (gitleaks v8.27.0)
- Covers: OpenShift tokens, K8s JWTs, AWS/Azure/GCP keys, PEM private
keys, generic secrets, GitHub PATs
- Keyword pre-filtering and binary detection for performance
- `--debug-only-skip-redact` flag for debugging (with prominent
warnings)

### 2. WebSocket Retrieve (replaces deprecated SPDY)

Sonobuoy uses `remotecommand.NewSPDYExecutor` which is deprecated since
Kubernetes 1.31 and causes transient failures (`unexpected EOF`,
`non-zero data after tar EOF`). See
[vmware-tanzu/sonobuoy#2032](vmware-tanzu/sonobuoy#2032).

The old inline-scanning approach **amplified** this SPDY bug: the
cleaner decompresses, parses, scans, and recompresses the tar.gz while
it streams over the network. Any network jitter during this process
corrupts the gzip/tar state, causing the entire retrieve to fail. With a
109 MB archive, the SPDY stream had to stay stable for ~30s of inline
processing — making failures almost guaranteed on retries.

This PR implements a custom `downloadFromPod()` that:
- Uses `remotecommand.NewWebSocketExecutor` as primary protocol
- Falls back to `remotecommand.NewSPDYExecutor` via
`NewFallbackExecutor` for older clusters
- Downloads to a temp file first (two-phase: download, then scan)

### 3. Two-Phase Architecture

Previously, scanning happened inline on the network stream — any jitter
caused corruption. Now:
1. **Download** — stream pod exec output to temp file on disk (fast, no
parsing)
2. **Scan/Redact** — process from disk (reliable I/O), then extract

This eliminates the SPDY corruption problem entirely: even if the
download uses SPDY fallback, the stream is just raw bytes to disk — no
gzip/tar parsing inline.

### Performance Comparison (same cluster, same archive, OCP 4.22.0-ec.5)

| Metric | main (SPDY, no scan) | PR (WebSocket + scan + redact) |
|--------|---------------------|-------------------------------|
| **Success rate** | ~50% (1 retry needed) | **100%** (first attempt) |
| **Wall clock** | 34s (incl. 1 retry) | **32s** |
| **User CPU** | 9.86s | 11.54s |
| **System CPU** | 0.95s | 0.64s |
| **Memory (RSS)** | 207 MB | 208 MB |
| **Context switches** | 214,521 | 40,013 |
| **Files processed** | N/A | 1,190 files |
| **Secrets redacted** | 0 | **17 findings** |

Key takeaways:
- **Same total time** (~32s) despite adding full leak scanning and
redaction of 1,190 files
- **5x fewer context switches** (40k vs 214k) — WebSocket is more
efficient than SPDY
- **100% success rate** vs main branch which failed on first attempt
with `unexpected EOF`
- Main branch needed a retry (SPDY bug) and still took 34s without any
scanning

## Changes

### New Files
- `internal/cleaner/leakpatterns.go` — 12 curated leak detection
patterns
- `internal/cleaner/leakscanner.go` — scan and redact implementation
- `internal/cleaner/leakscanner_test.go` — 20 unit tests + benchmarks
- `docs/devel/enhancements/2026-05-27-retrieve-leak-detection.md` —
enhancement doc

### Modified Files
- `pkg/retrieve/retrieve.go` — WebSocket+SPDY fallback executor,
two-phase retrieve
- `internal/cleaner/cleaner.go` — integrated redaction into tar
processing pipeline
- `internal/cleaner/cleaner_test.go` — updated test expectations for
redaction marker
- `.github/workflows/e2e.yaml` — E2E test for leak detection and
redaction
- `.gitignore` — exclude tar.gz archives

## Testing

**Unit tests** — all passing:
```
ok  github.com/redhat-openshift-ecosystem/opct/internal/cleaner  0.006s
```

**Live cluster test** (OCP 4.22.0-ec.5, K8s v1.35.3, 6 nodes, 109.5 MB
archive):
```
INFO Collecting results...
INFO Downloading archive from aggregator server...
DEBU Discovered aggregator server running on pod opct/sonobuoy...
INFO Downloaded 109.5 MB in 19s
INFO Scanning archive for sensitive data...
DEBU Finished processing 1190 files
DEBU Leak scan: 17 potential finding(s) detected and redacted
INFO Results saved to opct_202606081827_31f5f586.tar.gz
```
Wall clock: **32s** (vs 34s on main without scanning)

## Test plan

- [x] `make build` succeeds
- [x] `make test` — all unit tests pass
- [x] `make vet` — no issues
- [x] Live cluster retrieve completes in ~32s (same as main without
scanning)
- [x] Redaction markers present in output (17 findings)
- [x] Original secrets not present in output
- [x] `--debug-only-skip-redact` flag works with warnings
- [x] E2E test validates redaction end-to-end
- [x] WebSocket protocol with SPDY fallback for older clusters

## Summary
- Add `verify-images` job to `test-build-release` workflow that checks
all plugin images referenced in `pkg/types.go` exist on quay.io
- Gate the `e2e` job on `verify-images` so the pipeline blocks if any
image is missing
- Uses the public Quay v2 API (no auth needed) to verify manifests

## Why
When bumping versions in `pkg/types.go` for a release, if the
`provider-certification-plugins` CI failed to build/push the plugin
images, the OPCT binary would ship referencing non-existent images —
broken at runtime. This was flagged by CodeRabbit on PR #215 but had no
automated gate.

## Images verified
Extracted from `pkg/types.go`:
- `quay.io/opct/plugin-openshift-tests:TAG`
- `quay.io/opct/plugin-artifacts-collector:TAG`
- `quay.io/opct/must-gather-monitoring:TAG`

## Test plan
- [x] CI runs the new `verify-images` job and passes (current v0.6.5
images exist)
- [x] Local verification passes:
  ```
  ✅ quay.io/opct/plugin-openshift-tests:v0.6.5
  ✅ quay.io/opct/plugin-artifacts-collector:v0.6.5
  ✅ quay.io/opct/must-gather-monitoring:v0.6.5
  All plugin images verified successfully.
  ```
- [ ] Verify failure mode: temporarily change a version to non-existent
tag → job should fail

…canner (#223)

## Summary

leaktk-gcs-filter was replacing OPCT CI archives in GCS because PR
#219's scanner missed sensitive data. Ran leaktk scan with Red Hat
internal patterns against the CI archive from S3: 3157 findings before,
0 after this fix.

Fixes: OPCT-428

## Changes

### 1. Add .tar.xz nested archive support (internal/cleaner/cleaner.go)
Must-gather archives use .tar.xz compression. The scanner only recursed
into .tar.gz files, so .tar.xz archives (43 MB) were copied without
scanning. Added ScanPatchTarXzReaderFor() using the xz library already
in go.mod.

### 2. Increase scan size limit (internal/cleaner/leakscanner.go)
Changed maxLeakScanSize from 10MB to 100MB. The 60MB HTML/JSON test
result files inside nested archives were skipping the scan entirely.

### 3. Add 4 new leak patterns (internal/cleaner/leakpatterns.go)
- Generic Secret YAML (rnWF160pWNg): catches token:, secret:,
clientSecret: in YAML
- Authorization Header (QqS4RvI6Zmg): catches Authorization:
Bearer/Basic headers
- Broad JWT (RS256): catches OIDC/audience tokens beyond service account
JWTs
- Unescaped registry auth: catches pull secrets in unescaped JSON format

### 4. Remove files with encoded secrets (internal/cleaner/cleaner.go)
- Remove machineconfigs.json (percent+base64 encoded pull secrets,
leaktk decodes but OPCT does not)
- Remove all packagemanifests.json (base64-encoded PEM keys, previously
kept 1 copy)

## Test Results

```
BEFORE: 3157 findings (leaktk + Red Hat patterns)
AFTER:     0 findings
```

Tested with leaktk v0.3.3 using Red Hat pattern server
(patterns.security.redhat.com) against S3 archive
s3://opct-archive/uploads/5.0.0-0.nightly-2026-06-10-003138-20260611-HighlyAvailable-aws-External.tar.gz

## Test plan
- [x] go build succeeds
- [x] go test ./internal/cleaner/ — all tests pass
- [x] opct adm cleaner runs on CI archive, produces cleaned output
- [x] leaktk scan on cleaned output: 0 findings
- [ ] CI periodic job produces archive not redacted by leaktk-gcs-filter

## Summary

- Change plugin image references in `pkg/types.go` to use `latest` tag
on `main` branch
- Add GHA CI guard in `verify-images` job to block `latest` tags on
`release-*` branches
- Skip quay.io image verification when using `latest` tags

## Why

The 5.0 CI job already tests `opct:latest`. By using `latest` in
`types.go` on `main`, merged plugin fixes are immediately testable in CI
without waiting for a version bump PR. At release time, a PR to
`release-0.6` pins the versions to the specific release tag (e.g.,
`v0.6.6`).

## Changes

### `pkg/types.go`
- `ControllerImage`: `v0.6.5` → `latest`
- `PluginsImage`: `v0.6.5` → `latest`
- `CollectorImage`: `v0.6.5` → `latest`
- `MustGatherMonitoringImage`: `v0.6.5` → `latest`

### `.github/workflows/go.yaml`
- New step: "Block latest tags on release branches" — fails CI if
`types.go` has `:latest` on `release-*` branches
- Updated step: "Extract and verify plugin images" — skips quay.io
verification when using `latest` tags

## Impact on release process

- **Before:** PR to `main` to bump version → rebase `release-0.6` from
main
- **After:** Rebase `release-0.6` from main → PR to `release-0.6` to pin
version

See [OPCT-421 Phase 5](https://redhat.atlassian.net/browse/OPCT-421) for
updated release steps.

## Verification

- `make test` — all tests pass
- `go build ./...` — builds successfully

…OCP 4.20+ (#227)

## Summary

Update the OPCT documentation to unblock VCSP validations on OCP 4.20+
and
address the acceptance criteria from
[OPCT-389](https://redhat.atlassian.net/browse/OPCT-389).

### Changes
- Added `v0.6.5+` row supporting OCP 4.19-4.22 (CI workflows hardcode
`quay.io/opct/opct:v0.6.5`)
- Narrowed previous `v0.6.1+` to `v0.6.1-v0.6.4` covering 4.16-4.19
- Removed the OCPBUGS-77783 blocking notice
- Added info block documenting:
  - Affected versions: OPCT v0.6.0 and earlier do not support 4.20+
- Fix is in `openshift-tests` (openshift/origin), not in OPCT or plugins
  - OCP 4.20 was not affected by the conformance suite bug
- OCP 4.21+ needs nightly or z-stream with origin PR #31353 (4.21) /
#31270 (4.22)

### Why v0.6.5+ and not v0.6.1+ or v0.6.6+?
- All CI nightly workflows hardcode `OPCT_CLI_IMAGE:
"quay.io/opct/opct:v0.6.5"`
- The conformance fix is in openshift/origin, not OPCT — no OPCT code
change was needed
- v0.6.6 does not exist yet, and no changes after v0.6.5 are required
for 4.20+ support

### CI note
The `e2e / e2e-cmd_adm-parse-metrics` test fails on this PR due to a
missing
test artifact on CloudFront (HTTP 403). This is a pre-existing
infrastructure
issue unrelated to this docs-only change.

Fixes: https://redhat.atlassian.net/browse/OPCT-389
Epic: https://redhat.atlassian.net/browse/OPCT-421

## Test plan
- [ ] Verify version matrix renders correctly on the published docs site
- [ ] Verify info block renders correctly
- [ ] Confirm no other docs reference the removed blocking notice

…g builds (#198)

## Problem

The `only-new-issues: true` flag in golangci-lint-action fails on tag
pushes because there's no base commit to compare against.

When building from a tag (like `v0.6.1`), the action tries to compare
with commit `0000000000000000000000000000000000000000` which results in
a 404 error:

```
failed to fetch push patch: RequestError [HttpError]: Not Found
url: '.../compare/0000000000000000000000000000000000000000...COMMIT'
```

This broke the v0.6.1 release build:
https://github.com/redhat-openshift-ecosystem/opct/actions/runs/19982041880

## Solution

Remove the `only-new-issues` flag from
`.github/workflows/pre_linters.yaml` line 65.

This allows golangci-lint to run on the full codebase for all builds
(PRs, branches, and tags), which is acceptable since:
- The code was already linted when merged to main and release-0.6
- Tag builds should validate the entire codebase anyway
- The lint check completes quickly enough (~30 seconds)

## Impact

- ✅ Fixes v0.6.1 release build
- ✅ Prevents similar failures in future releases
- ⚠️ May show more lint issues in PR builds (previously only showed new
issues)

## Testing

After merge:
1. Delete and recreate v0.6.1 tag
2. Verify CI build succeeds
