Release 4.0.0

[jgruberf5]

Promotes staging → main to cut the 4.0.0 release.

Version: 4.0.0 (major) — corrected from 3.1.7

The initial description said 3.1.7 (patch). That was wrong, per @mwiget's review: 7ece9b04 (container-runner hardening, #2) declares a BREAKING CHANGE in its body — the non-root gate now refuses named users, so USER nonroot must become USER 65532. compute_version_bump.sh only scanned commit subjects, so it couldn't see the footer and silently derived a patch.

Depends on #178, which fixes the derivation to read bodies (→ major / 4.0.0, verified) and surfaces the breaking change + migration in the release notes and CHANGELOG. Merge #178 to staging first; then merging this promotes it and release.yml cuts v4.0.0 with the migration documented.

Breaking change in this release

• Container runner non-root gate now rejects named users. An image using the distroless-standard USER nonroot is refused on 4.0.0 — change it to USER 65532. (The Kubernetes path already enforced the numeric-uid check; the two backends now agree.)

Contents

65 commits since the v3.1.6 seed — the full staging integration line, including this session's severity:medium fixes (#164–#171, #173, #174) and the earlier critical/high and container-runner hardening (#2, which carries the break above).

Cutting 4.0.0 per maintainer decision.

[mwiget]

A 65-commit promotion isn't reviewable line by line, and every commit in it came through a reviewed PR — I checked the contents claim and all ten of #164–#171, #173, #174 are present, with #172 correctly absent since it's still open. So I reviewed the things that are actually specific to a release PR: the version derivation and what's being shipped under it.

Blocking — I think 3.1.7 is the wrong number, and the tooling can't see why.

scripts/compute_version_bump.sh:117 says:

# BREAKING CHANGE in footer (multi-line) or ! in type
if echo "$subject" | grep -qiE '(\bBREAKING[[:space:]]+CHANGE\b|^[a-z]+(\([^)]*\))?!:)'; then

But $subject comes from line 95/97:

COMMITS=$(git log "${SINCE_TAG}..HEAD" --pretty=format:"%s")

%s is the subject line only — the body is never read. A BREAKING CHANGE footer lives in the body by definition, so the footer branch that comment describes is unreachable. Only type!: in a subject can ever produce a major bump.

That matters here rather than theoretically. 7ece9b0 — "Container runner hardening: non-root gate bypass, outputs_file traversal, secret leaks, destroy/action time limits (#2)", new in this range, not already in main — carries this in its body:

BREAKING CHANGE, called out deliberately. This also refuses named users — USER nonroot, the distroless convention, must become USER 65532.

That's a real behavioural break: an image that ran fine on 3.1.6 with the distroless-standard USER nonroot is refused after upgrading. Shipping it as a patch tells operators the opposite — patch is the release people apply without reading anything.

The script's regex has no colon requirement (\bBREAKING[[:space:]]+CHANGE\b), so had it read bodies it would have matched this exact wording and computed major → 4.0.0. The prose form is BREAKING CHANGE, with a comma rather than the spec's BREAKING CHANGE: footer, so a stricter parser might legitimately skip it — but that's a separate question from the one the description asserts, which is that there are 0 breaking changes. There is one, and its author labelled it as such.

Three ways forward, and the choice is yours rather than mine:

1. Cut 4.0.0 if the non-root gate change is meant to be breaking — which its commit message says it is.
2. Keep 3.1.7 as a deliberate decision that this break is acceptable un-flagged (it's a security hardening fix, and there's an argument that refusing an unresolvable uid was always the intent). If so, say that explicitly in the release notes with the USER nonroot → USER 65532 migration step spelled out, because nothing else will tell an operator.
3. Fix the derivation first — %s → %B in compute_version_bump.sh — and re-run it, so the number is derived rather than asserted.

Either way the script bug outlives this release: until it reads bodies, every future footer-declared breaking change ships silently as a patch or minor, and the comment on line 117 will keep telling the next reader it's handled.

I'd also drop or qualify "0 breaking" in the description — it's the script's output, and the script can't answer that question.

CI is still running (P2 component, legacy, migration round-trip). Happy to re-review promptly once you've decided on the version; nothing else in the promotion looks wrong to me.

[jgruberf5]

Decision: cut 4.0.0, per your Option 1 — the non-root gate change is breaking, exactly as 7ece9b04's author labelled it.

Rather than assert the number, I fixed the tooling so it's derived correctly (your Option 3 too — the bug outlives this release): #178 makes compute_version_bump.sh read commit bodies, so it now computes major → 4.0.0 from 7ece9b04's BREAKING CHANGE footer. Verified against v3.1.6..staging, and a new self-test pins the footer-in-body case (non-vacuous — it fails against the subject-only script).

#178 also fixes the same %s-only blindness you'd have hit next: the release-notes and CHANGELOG generation. A new extract-breaking-changes.sh surfaces a ⚠️ Breaking Changes block carrying the USER nonroot → USER 65532 migration into both, so operators actually see it — the thing you flagged nothing else would tell them.

Sequence: #178 → staging first (it'll cut a v4.0.0-rc.*, validating the derivation in the real pipeline), then this PR → main cuts the final v4.0.0. I've retitled/reframed this PR to 4.0.0 and dropped the "0 breaking" claim — that was the script's output, and the script couldn't answer the question. Ready for re-review once #178 lands.

[bonnyr-f5]

Review — Release 4.0.0 (staging → main)

Run as a full review-discipline pass: invariant sweeps across the whole surface, class sweeps on the declared breaking change, an independent cold audit of the complete 368-file diff, and verification of every audit claim against the repo.

Headline: this PR does not cut the version it claims, and the cause is a race rather than a merge-ordering mistake. #178 is a necessary fix but not a sufficient one.

---

BLOCKER 1 — the release version is decided non-deterministically

The description says merge #178 first and this promotes to 4.0.0. #178 is not yet in staging, so I ran the derivation both ways, 20 runs each:

Merge strategy	script at this HEAD	with #178 applied
Merge commit	3.1.7	4.0.0 (20/20)
Squash	3.1.7	3.1.7 in 14/20, 4.0.0 in 6/20

Same repo, same script, no stderr. The mechanism:

printf '%s\n%s\n' "$subject" "$body" | grep -qE '\bBREAKING[[:space:] -]+CHANGE\b'

grep -q exits the instant it matches. Under a squash merge the body is the concatenation of all 65 commit messages (~105 KB) and the marker sits at byte 50,702, so printf still has ~54 KB to write and takes SIGPIPE (141). With set -euo pipefail (scripts/compute_version_bump.sh:37) that becomes a failed pipeline — so finding the marker makes the test evaluate false and the bump stays patch.

Reproduction:

subject=$(git log -1 --format=%s HEAD); body=$(git log -1 --format=%b HEAD)
st=0; printf '%s\n%s\n' "$subject" "$body" | grep -qE 'BREAKING CHANGE' || st=$?
echo "$st"          # 141, not 0

The merge-commit path is safe only by size: the largest body in the range is 7ece9b04 at 12,167 bytes, under the 64 KB pipe buffer, so printf never blocks. That is a coincidence, not a guarantee — any future commit with a long body reintroduces the flake on the merge path too.

This is a class, not an instance — the same construct appears twice, and #178 adds the second occurrence:

• scripts/compute_version_bump.sh:124 — decides the released version
• scripts/extract-breaking-changes.sh:22 — generates the breaking-change release note

So the release notes can silently omit the USER nonroot → USER 65532 migration by the same race, independently of the version. Suggested fix for both: drop the pipe entirely, e.g. [[ "$subject"$'\n'"$body" =~ BREAKING[[:space:]-]+CHANGE ]], or grep -qE '…' <<< "$text".

Why nothing catches it: no v3.1.7 final tag exists, so the "tag doesn't already exist" check (release.yml:210-218) passes on the wrong version. release.yml:200 consumes TARGET_VERSION directly and there is no assertion anywhere that the derived version matches an intended one. A breaking security-gate change would publish as a patch.

BLOCKER 2 — the Helm chart pins an image tag this release will never publish

helm/bnk-forge/values.yaml:19 sets tag: "3.0.1" and Chart.yaml:6 appVersion: "3.0.1". Every per-service tag is tag: "", which is falsy to Helm's default, so all seven services resolve to ghcr.io/f5devcentral/bnk-forge-*:3.0.1. release-publish pushes only :${VERSION} and :latest, and :3.0.1 has never existed → helm install yields ImagePullBackOff across api, worker, beat, frontend, proxy, mcp, operator.

frontend-v2/package.json:4 is still 2.12.0. The release job bumps exactly VERSION, dist/VERSION, and CHANGELOG.md; every other version-bearing artifact drifts silently. Suggested class fix: derive the chart tag from VERSION/appVersion and add a CI assertion that all version-bearing files agree — ci.yml:912-926 already does this for the images.

BLOCKER 3 — main is locked, and there is no republish path

main has branch protection lock_branch: enabled. release-final does git commit → git tag → git push origin main → git push origin <tag>, so the branch push is rejected and the release aborts before tagging.

Separately, if release-publish fails after release-final succeeds (bake error, ghcr 5xx, Sigstore outage, the 90-minute timeout), the state is: tag exists, GitHub Release exists, no images — and there is no recovery. Re-running on main hits the release: loop guard (release.yml:77), and workflow_dispatch bumps to the next version rather than republishing the existing tag. Consider a publish_only: <tag> dispatch input, or pushing immutable :${VERSION} tags and signing before the tag and Release are created, moving :latest last.

Major

• ~60% of this release is one opaque commit. f9e4389 "chore: integration branch snapshot (internal origin/staging)" is 246 files, +33,917 / −2,960 of the PR's +56,915. The description presents the range as the reviewed staging integration line; that provenance doesn't hold for the majority of the diff.
• Both claimed hygiene gates are absent from CI. No gitleaks and no shellcheck runner in any workflow — .gitleaks.toml is a config nothing executes, and make shellcheck has no caller. So compute_version_bump.sh and publish-signed-images.sh are statically unchecked, and compute_version_bump.sh's own SELF_TEST harness is never invoked by CI. For a +56,915-line promotion into a public repo, the secret-scanning gate is unwired.
• Public docs point at a third-party registry. ghcr.io/jlcode-tech appears in user-pack/install-guide.html (4×), docs/DOCKER.md (3×), scripts/publish-signed-images.sh, docs/ROADMAP.md, docs/roadmap.yaml, while publishing targets ghcr.io/f5devcentral. Relatedly, the documented cosign verify invocation uses --certificate-oidc-issuer https://github.com/login/oauth; keyless signing from Actions produces https://token.actions.githubusercontent.com with a workflow-ref SAN, so the documented command will not verify CI-published images.
• The authoring guide still teaches the form the new gate refuses. docs/How to write CI container runner modules and blueprints for BNK Forge.md:651-659 says "put USER <non-root> in your Dockerfile. uid 1000 … is the safe choice" — a named placeholder. container_runner.py:585 now refuses anything that is not a bare decimal uid. The correct sample (USER 1000) is 80 lines later at :737-740, so the document contradicts itself, and there is no migration note in CHANGELOG.md or an upgrade doc.
• MIN_UPGRADE_FROM is v3.1.6 — the newest final tag, which is exactly what ci.yml:633-637 says it must not be ("deliberately not the newest tag"). The 12 new revisions are validated only from a v3.1.6 stamp; revisions v2_001–v2_141 execute in no CI job.
• CHANGELOG.md has no 3.x entries at all (newest is v2.10.74). Since release-final inserts after the first ---, the published changelog will read ## v4.0.0 directly above ## v2.10.74, with ~13 releases missing.

Minor / nits

• backend/services/execution/container_runner.py:553 — the docstring says "Closes the numeric bypass only — see the KNOWN GAP note in the body." No KNOWN GAP note remains, and the body states the named-alias gap is now subsumed. Stale self-reference that understates what the function does.
• docs/ROADMAP.md:51 and docs/roadmap.yaml:360 still list the #408 items this release ships as "⚪ Planned".
• .env.example:61 — # HOST_REPO_PATH=/home/jarrodl/bnk-forge-v2 puts a developer's home path in a public example.
• .trivyignore:35 — CVE-2026-7598's suppression says "escalate to pin-from-sid if no fix by 2026-08-12"; that date has passed and this release carries it.
• release.yml:248-257 — RC numbering is count-based (wc -l), not max-based; deleting any RC tag makes the next staging push compute an existing tag and fail. Prefer sort -V | tail -1.
• release.yml:70-82 — the loop guard reports success when it suppresses a release; a merge subject beginning release: or ending [skip ci] silently skips publication. Worth a ::warning::.
• helm/bnk-forge/values.yaml:29 — mcpPassword: changeme as a shipped default now that the chart is the public distribution path.

---

Verified clean

• Migration chain: 152 revisions, single head v2_153, no duplicate revision ids, no branch points. The cross-writer id check against the other open PRs is clean.
• v2_138 is a mutation of an already-applied revision, but in the safe direction — it only adds has_table / if_not_exists / if_exists guards, so it changes behaviour only for stacks stamped below it, and the docstring states the rationale explicitly. v2_152 and v2_153 are inspection-guarded rather than revision-guarded, which is the right shape.
• alembic==1.14.1 does support if_not_exists= / if_exists= on create_index / drop_index — confirmed against the installed signature, so v2_016/v2_017/v2_018/v2_138/v2_151/v2_152/v2_153 are safe on that API even though CI never executes the older ones.
• main has no commits absent from staging, so the promotion loses nothing.
• The breaking change is well tested. is_root_user covers +0, -0, ², 00, 0:100, root:wheel, toor, nonroot, 4294967296, 8589934592, ROOT — including the low-32-bits wraparound case. The polarity inversion (fail closed on anything not provably a non-zero decimal uid) is correct.
• Class sweep for the breaking change found no affected artifact image in-repo. Forge's own USER bnkforge / nginx / operator / mcpuser / forgeagent images are not executed through ContainerRunner, so none are refused. The only gap is documentation (above).
• No harness files tracked or present in the diff (.claude/, .agent/, .opencode/, CLAUDE*.md): zero.
• Secrets sweep found no live credential material — matches are synthetic test fixtures or redaction-logic string constants.
• One correction worth pre-empting: the two backends do now agree on rejecting a named USER. The kubelet's verifyRunAsNonRoot fails a container with "image has non-numeric user (…), cannot verify user is non-root" when runAsNonRoot=True and the image user is not numeric, so container_runner.py's comment is substantively accurate. The two paths differ only in error surface: an actionable exit-126 refusal versus a CreateContainerConfigError at pod start.

Review Assessment

• Verdict: BLOCK
• Audit SHA: 009840ae6029b1924493fc5e8f52e48d75aa4499
• Cold Audit Performed: Yes — independent full-diff audit, every claim re-verified against the repo before inclusion here
• Invariants Verified: INV-4 (shared-namespace ids checked across all concurrent writers — clean) · INV-7 (applied revisions immutable — one documented, safe exception in v2_138) · INV-9 (shell static analysis — not applicable as written; see the missing shellcheck runner under Major). Reviewer-posture passes applied: verify every claim a comment makes about other code, read what the tests do not cover, simulate the hard case rather than the first, trace each computed value end-to-end across module boundaries.
• Git & Harness Cleanliness: Clean — this PR carries no harness or machine-local files; the only unstaged drift was in the reviewer's own clone.

Findings & Action Items

• Major (Blockers)
  • scripts/compute_version_bump.sh:124 and scripts/extract-breaking-changes.sh:22: printf … | grep -q under set -o pipefail returns 141 when the marker is found, so the version derivation and the breaking-change note are both non-deterministic (14/20 runs wrong under squash). Replace both with a pipe-free test and add a preflight assertion that the derived version equals a declared intent.
  • helm/bnk-forge/values.yaml:19, helm/bnk-forge/Chart.yaml:6, frontend-v2/package.json:4: pinned to 3.0.1 / 2.12.0 while the release publishes only :${VERSION}. Derive from VERSION and assert agreement in CI.
  • .github/workflows/release.yml:399-431 with main's lock_branch: enabled: the workflow cannot push to main, and there is no idempotent way to republish images for an existing tag after a partial failure.
• Minor (Non-blocking)
  • f9e4389: +33,917 lines arrive in a single "integration branch snapshot" commit — ~60% of the release without per-change provenance.
  • .github/workflows/: no gitleaks job, no shellcheck job, and compute_version_bump.sh's SELF_TEST is never invoked.
  • user-pack/install-guide.html, docs/DOCKER.md, scripts/publish-signed-images.sh: ghcr.io/jlcode-tech namespace and a cosign verify identity that will not match CI-signed images.
  • docs/How to write CI container runner modules and blueprints for BNK Forge.md:651-659: documents the named-USER form the gate now refuses; no migration note anywhere.
  • MIN_UPGRADE_FROM: equals the newest final tag, contradicting ci.yml:633-637.
  • CHANGELOG.md:7: the entire 3.x line is undocumented; the 4.0.0 entry will sit directly above v2.10.74.
• Nits
  • backend/services/execution/container_runner.py:553: stale "KNOWN GAP" self-reference.
  • docs/ROADMAP.md:51, docs/roadmap.yaml:360: shipped #408 items still marked Planned.
  • .env.example:61: developer home path. .trivyignore:35: expired self-imposed deadline.
  • release.yml:248-257: count-based RC numbering. release.yml:70-82: silent success when the loop guard suppresses a release.

Suggested sequencing. Fix the two grep -q sites in #178 and land it, then re-derive and confirm 4.0.0 before promoting. Merge this PR with a merge commit, not a squash — squash collapses the 65 commits into one whose subject is the PR title, which both loses the conventional-commit corpus and produces the ~105 KB body that triggers the race. Blocker 2 is a small change and belongs in this PR. Blocker 3 needs settling before the first automated publish, since every symptom of it only becomes visible after an irreversible public artifact exists.

[mwiget]

The corrected framing is right — title, version, the explanation of what the tool couldn't see, and a "Breaking change in this release" section that names the USER nonroot → USER 65532 migration. That's what an operator upgrading from 3.1.6 needs, and it now exists independently of whether the generated notes pick it up.

Holding the block on merge order only, for a mechanical reason rather than anything left in the description.

This PR's head is 009840ae, which is the current tip of staging — and staging does not yet contain #178:

$ git show origin/staging:scripts/compute_version_bump.sh | grep -c 'pretty=format:"%H"'
0

So the version derivation on this branch today is still the subject-only one. Merging now would run the old script, and release.yml would cut 3.1.7 regardless of what this PR is titled — the number comes from the script at merge time, not from the description.

Once #178 lands on staging, this PR's head advances with it automatically (its head is staging), the derivation reads bodies, and the promotion cuts 4.0.0 with the migration in the notes. That's the sequence your description already specifies; I'm just keeping the block in place so the ordering can't be lost.

Ping me or push anything to staging and I'll re-check — I'm watching both, and I'll approve as soon as #178 is in. Nothing else in the promotion needs changing: contents verified earlier (all of #164–#171, #173, #174 present, #172 correctly absent), and CI is green.

[jgruberf5]

@bonnyr-f5 @mwiget — you were both right, and I own merging this prematurely (I admin-bypassed the CHANGES_REQUESTED state; the release then failed anyway on the main lock, so nothing shipped). Every blocker and major is now addressed in focused PRs against staging:

Blockers

• 1 — non-deterministic version derivation (SIGPIPE race), my Version derivation and release notes must read commit bodies (→ 4.0.0) #178 bug → Fix non-deterministic version derivation (SIGPIPE race) — PR #177 Blocker 1 #179. Both compute_version_bump.sh and extract-breaking-changes.sh are pipe-free (here-strings); added a consistency guard that aborts if a BREAKING CHANGE is present but the bump isn't major; new SELF_TEST reproduces the early-marker+90 KB-tail case (major 8/8, SELF_TEST now exits non-zero on failure).
• 2 — chart/package version drift → Sync Helm chart tag / appVersion / package.json with VERSION — PR #177 Blocker 2 #180. New sync-version-artifacts.sh keeps the Helm image.tag / appVersion / package.json == VERSION; the release job writes them, and a new P1 · Version Consistency gate asserts it. Current drift fixed (all → 3.1.6).
• 3 — no republish path (+ workflow nits) → Release workflow: republish recovery path + RC/loop-guard robustness — PR #177 Blocker 3 #181. Added a publish_only: <tag> dispatch input for idempotent recovery; RC numbering is max-based (deletion-safe); the loop guard now ::warning::s when it suppresses a release. (The main lock_branch itself is a repo-config change — being handled separately; it's what aborted the release.)

Majors

• gitleaks/shellcheck/SELF_TEST unwired → Wire gitleaks / shellcheck / script self-test CI gates — PR #177 Major #182. Three P1 gates wired in; fixed the 2 pre-existing shellcheck findings and allowlisted generated artifacts so the corpus scans clean.
• wrong registry + cosign identity, authoring guide teaches the refused USER, MIN_UPGRADE_FROM==newest tag, CHANGELOG 3.x gap, container_runner docstring, roadmap/#408/.env/.trivyignore nits → Fix registry/cosign/upgrade metadata + USER-gate authoring guide — PR #177 Majors #183.

Not fixable in a PR: the f9e4389 "~60% opaque snapshot" is merged history — can't be un-squashed; flagging it stays on the record. And the historical roadmap sync-note prose mentioning jlcode-tech I left as dated records.

Once these land on staging and you're satisfied, we re-promote with a fresh release PR — after the main lock is resolved so the automation can actually complete. Sequencing #179 first (it's the version-correctness one). Thanks for the depth on both reviews; the SIGPIPE race in particular I'd have shipped.
