In @.claude/commands/z-stream-release-check.md:
- Around line 16-19: The docs and script disagree: update
hack/z-stream-release-check.py so IMAGE HEALTH matches the markdown by (1)
treating images with Critical or Important CVEs as "action needed" (not
informational-only) when computing the grade/flag, and (2) showing the actual
"threshold crossing" date for images already below B instead of printing `--`.
Locate the reporting logic in functions named like generate_image_health_row or
format_image_health_table (and any CVE filter/threshold-check helper) and change
the CVE severity check to mark Critical/Important as degradations and remove the
code path that replaces threshold dates with `--` for degraded images so the
real threshold date is displayed.
In `@hack/z-stream-release-check.py`:
- Around line 1423-1426: When computing the previous OCP minor for pre-release
branches, don't compute prev_ocp_minor by decrementing ocp_parts_pr[1] (which
yields invalid values like "5.-1"); instead, find the previous released minor by
locating ocp_minor in the ordered list of branches/tags (all_tags) and taking
the immediate predecessor. Update the block that sets prev_ocp_minor and
base_tag (the code using ocp_minor, ocp_parts_pr, prev_ocp_minor and calling
_find_pre_release_base_tag) to look up the prior entry in the sorted/ordered
branch/tag sequence and pass that value to _find_pre_release_base_tag so
major-version rollovers are handled correctly.
- Around line 726-730: The except block around the call to _fetch_support_dates
currently swallows RuntimeError and sets support_dates = {}, which must instead
be treated as a fatal lifecycle API failure; update the except RuntimeError as
exc handler to log the error (same stderr message) and then call sys.exit(2) (or
re-raise) instead of assigning an empty dict so the process fails fast and does
not continue with empty support_dates.
- Around line 1620-1629: The fetch_unreleased_prs error path stores an "error"
in result["unreleased"] but the downstream branch-clear logic still treats that
branch as "No action needed"; update the decision at the branch disposition
point to check unreleased.get("error") and treat any non-empty error as a
non-clear state (or fail the run for critical API errors). Specifically, when
evaluating the "clear" condition that currently inspects unreleased["ahead_by"],
unreleased["total_prs"], etc., add a check like: if unreleased.get("error"):
mark the branch as needing attention (or raise/exit) so branches with failed
compare calls cannot be reported as ✓ No action needed; refer to
fetch_unreleased_prs, result["unreleased"], and the unreleased variable in that
decision logic to implement this.

In `@hack/z-stream-release-check.py`:
- Around line 2197-2199: Update the GitHub branch fetch exception handler in the
branch-fetching flow to treat requests.RequestException as a fatal API error,
matching the existing tag and catalog fetch handling and the contract described
by the module. Remove the warning-and-empty-list fallback and propagate the
failure through the established exit-code-2 path so run_checks cannot produce a
normal recommendation from incomplete branch data.
- Around line 1260-1266: Update the total_prs calculation in the result-building
return block so PRs reclassified as bots during the second pass are not counted
twice; preserve the existing team_pr_numbers and bot_filtered reporting, and
either capture the pass-1 bot count separately or compute the total before pass
2 modifies bot_filtered.

.claude/commands/z-stream-release-check.mdhack/z-stream-release-check.py
Included review availability: Your plan provides up to 12 included reviews per hour; 11 remain after this review.
Introduces hack/z-stream-release-check.py and a companion Claude slash
command (.claude/commands/z-stream-release-check.md) for determining
which WMCO release branches need a z-stream release. Run before sprint
planning to produce a per-branch report covering image health,
unreleased PRs, and a concrete sprint recommendation.
Data sources
- Red Hat Container Catalog (catalog.redhat.com): WMCO operator image
freshness grades (A–F) and CVE vulnerability counts per branch.
Also fetches ubi9/ubi-minimal base image grade to assess whether a
rebuild would extend the grade window.
- OCP Lifecycle JSON API (access.redhat.com): EOM dates per OCP minor
version from the phases[] array. Uses EUS Term 2 end dates for OCP
4.18+ / WMCO 10.18+ when available; falls back to Maintenance
support end dates for all other releases.
- GitHub API (api.github.com): release branches, tags, and PR
metadata. Uses the Compare API to find commits on each branch since
its last release tag, then fetches per-PR file lists to filter
non-shipped changes.
- Jira (redhat.atlassian.net): open release Epics and Tasks in the
WINC project. Optional; requires JIRA_API_TOKEN + JIRA_USERNAME.
Shown as supplementary context only — does not affect
recommendations.
Branch classification
- In catalog (active): RHEL9 catalog entry exists; support status
determined by OCP lifecycle API.
- Pre-release: branch exists in GitHub but no release tags yet —
the newest branch still tracking master. Shown with [PRE-RELEASE];
skipped in image health and sprint recommendation. Use
--pre-release-prs to fetch and display unreleased PRs for it.
- Old EOM / pre-RHEL9: tagged but not in RHEL9 catalog (e.g.
release-4.17 and earlier). Hidden by default; shown with --all.
- OCP 4.x below 4.15: predates WMCO 10.x entirely; always classified
as old EOM without tag checks.
Image health (Container Health Index)
Grade A–F is time-based (age of oldest unpatched Critical/Important
erratum). Release recommendation triggers when:
- Grade is below B (C, D, E, or F) — image needs a rebuild now.
- Grade is A or B but will drop within SPRINT_LOOKAHEAD_DAYS (21
days) — sprint planning happens at sprint start; a release may
not ship until sprint end, so upcoming degradation must be acted
on now.
The Threshold Date column shows when the grade first crosses below B:
- For A/B images: the upcoming deadline.
- For already-degraded images: the column is suppressed since the
catalog API generates start_date dynamically from today.
CVE counts (C/I/M/L) are informational only and do not trigger
recommendations — the grade already encodes CVE timeliness.
Base image rebuild value (ext ✓ / same / ↓ / —) indicates whether
rebuilding from ubi9/ubi-minimal:latest would extend the grade
window; advisory only, does not trigger recommendations.
Unreleased PR detection
Uses the GitHub Compare API (tag...branch) to find merge commits
since the last release tag. Smart filtering excludes:
- Bot bump PRs by branch prefix: konflux/, mintmaker/, renovate/,
dependabot/. openshift-cherrypick-robot PRs are kept (they carry
real bug/CVE fixes).
- Bot PRs by GitHub login: openshift-bot, openshift-merge-robot,
openshift-ci-robot.
- Non-shipped PRs: PRs where every changed file matches test/,
docs/, or hack/ prefixes, or the CI skip-if-only-changed pattern
(ote/, .github/, .tekton/, *.md, root config files including
.coderabbit.yaml). Conservatively treated as shipped on fetch
failure.
- Version-bump PRs ("Update version to X.Y.Z"): shown as [INFO]
to indicate release prep has started but do not themselves
trigger a recommendation.
Any remaining non-bot, non-version-bump team PR triggers a release
recommendation.
Sprint recommendation logic (any one condition is sufficient)
✗ UNRELEASED PRs — shipped team PRs exist since the last release tag
✗ IMAGE GRADE — current grade below B (C/D/E/F)
⚠ UPCOMING GRADE — grade A/B now but drops within 21 days
Output modes
Default: four-section human-readable text report (RELEASE BRANCHES,
IMAGE HEALTH, UNRELEASED PULL REQUESTS, SPRINT RECOMMENDATION) with
ANSI color coding, auto-disabled when stdout is not a TTY.
--json: machine-readable JSON with all fields; progress suppressed.
--connectivity: probe all required APIs and exit.
--all: include past-EOM and pre-RHEL9 branches in output.
--branch BRANCH: restrict output to a single branch.
--pre-release-prs: fetch and display PRs for pre-release branches.
Other
- Progress feedback shown for all remote fetching; one dot per PR
detail + file-check round trip.
- Retry-enabled GET wrapper handles transient network failures.
- Paginated fetching for catalog images, GitHub branches, tags, and
PR file lists.
- Exit 0 on success regardless of recommendations; exit 2 on fatal
connectivity or API errors.
- OCP major → WMCO major mapping: ocp_major + 6 (OCP 4 → WMCO 10,
OCP 5 → WMCO 11), used throughout for tag patterns, Jira
fixVersion parsing, and support date lookups.
- EUS Term 2 eligibility: OCP 4.18+ (WMCO 10.18+) or any OCP 5.x+
when the lifecycle API provides an EUS Term 2 end date.
