CI-4: make every allow-fail unit blocking or remove it; Containerfile reproducibility replaces the Guix job - #476
This PR applies the CI-4 ruling (#416, owner 2026-11-05): every allow-fail unit is made blocking or deleted, never re-dated. The units expire on 2026-11-30, and W0 exit check (8) runs check-allow-fail-expiry.sh as of 2026-12-01. On this branch that check counts 0 units; on main it counts 9.
On the T1 Guix job, the owner chose to retire it and add a Containerfile reproducibility check in the same PR, rather than delete it with nothing in its place.
Changes
Made blocking. Each of these was green on main when the change was made.
container-citier3-container. All 8 cells passed on main on 2026-11-08 (run 42453284210), stub-sentinel detection included. It now runs weekly and on dispatch. I dropped its head_commit.modified condition, which never matched.
live-provers tier-2 provisioning, and tier 3 (job and step).
Removed.
tier4 and tier4-gpu. One only echoed a TODO, and the other never provisioned GPUVerify or Faial.
boj-build.yml. It failed on every push to main: it was plain http to boj-server.local, with a malformed JSON body.
T1 Guix manifest check. Retired by the ruling.
The Guix check is replaced by a reproducibility check.
container-build and a new container-rebuild build the minimal image on two independent runners, both with --no-cache --timestamp 0.
container-reproducible requires the same image ID. If the IDs differ, it lists both builds' layer digests so the drifting layer can be found.
I checked the mechanism locally with podman 4.9: with --timestamp 0, two builds give the same ID, and without it they differ.
Whether the full Containerfile is reproducible is what this PR's container-ci run tests. I'll report the result here.
Isabelle runs again instead of being skipped.
scripts/ci/install-isabelle.sh pins Isabelle2025-2 and its SHA-256. It tries https-only mirrors, release archives (website-<release>/dist/) first.
The tier-2 nightly's TUM dist/ URL redirected to http:// and reset connections.
The weekly Isabelle/HOL job's Cambridge dist/ URL returns 404 because the release was superseded (job 128978199538). That is one of the reds on main.
Both jobs now call the script.
NOT RUN is recorded, not hidden. ProVerif, twelf and the OR-Tools tarball are unavailable on the runner image. Each writes NOT RUN to the step summary. Their containerised builds stay covered by tier3-container.
Docs.
Dated notes added to the Chapel decision record and to docs/handover/{STATE,TODO}.adoc.
manifests/live-provers.scm now says it has no CI consumer.
actions.lock. It still lists the deleted boj-build.yml. The lock is tool-owned, so I'm refreshing it through the ci:refresh-actions-lock label, not by hand.
History. This branch merges main instead of rebasing. The merge commit takes main's version of each workflow. The second commit applies the dispositions to main's text.
RSR Quality Checklist
Required
Tests:check-allow-fail-expiry.sh --today 2026-12-01 exits 0 with 0 units.
Formatting: not applicable; workflows and shell only.
Lint:
shellcheck is clean on install-isabelle.sh.
The changed workflows parse with Ruby Psych, and every needs: entry resolves.
I could not run actionlint here; the Workflow security linter runs in CI.
No banned language patterns.
SPDX headers on new files.
No secrets.
As Applicable
Documentation updated (decision record note, handover notes, manifest header).
Testing
Run in this PR's CI.container-ci (it changes) and verification-proofs-cron (its path filter now includes the installer) both run on this PR.
Not run here. I couldn't reach these from this sandbox:
the Isabelle mirrors (the proxy refuses them);
a full image build;
actionlint.
The PR's runs are the evidence. I'll report them on this PR before marking it ready.
Owner ruling 2026-11-05 (CI-4): each allow-fail unit is made blocking or
deleted, never re-dated. A unit was made blocking only where recent runs
show it passing; the rest were deleted or fixed in place.
Blocking: static-analysis-gate hypatia-scan "Setup Elixir" and "Clone and
build Hypatia"; chapel-ci rust-chapel-feature; live-provers tier3 job;
live-provers tier2 and tier3 provisioning steps, where the two backends
whose provisioning failed (isabelle download reset, proverif missing from
apt) now degrade with a ::warning:: and SKIP as they already did.
Deleted: boj-build.yml (posts to boj-server.local, unreachable from a
hosted runner, exit 2 on every run); container-ci tier3-container (all 8
cells fail on the 2026-11-01 run with E0391 from the unpinned nightly in
Containerfile.wave3); chapel-ci rust-chapel-real (undefined chapel_*
symbols on main, #408); live-provers tier4 (echo only) and tier4-gpu
(job and both steps; neither binary was ever provisioned).
CI-3: the T1 Guix manifest job is retired by owner ruling; the Containerfile
is the reproducibility path.
check-allow-fail-expiry.sh now reads FAKE_DATE when --today is absent, so
`FAKE_DATE=2026-12-01 scripts/ci/check-allow-fail-expiry.sh` is the W0 gate
form. It exits 0 with 0 units after this change, and 1 on origin/main (14
expired) and on a planted expired unit.

Hypatia's code_safety/zig_ptr_cast and zig_align_cast now flag the nine
`@ptrCast(@aligncast(raw))` lines in src/zig_ffi/chapel_bridge.zig and
src/zig_ffi/runtime_owner.zig as high, and the governance Hypatia
baseline gate is red on main (2ab7574) as a result.
Each of those lines recovers a callback's own `*@this()` from the
type-erased `*anyopaque` it was registered with (runtime_owner.Work
.context, or a std.mem.Allocator vtable's ptr), so the cast restores the
original type and alignment. Fixed at source with a reasoned inline
`hypatia: allow` per rule on each line, as the scanner documents,
rather than a baseline entry. No code change: comments only.
Checked by simulating ScannerSuppression.inline_allowed?/4 and
directive_re at hypatia 82396d81 (the CI pin): 18 unsuppressed
findings on main, 0 with this change. The scanner itself could not be
built here (hex.pm is unreachable).

Conflicts in chapel-ci.yml, live-provers.yml and static-analysis-gate.yml
are resolved by taking main's version of each workflow, container-ci.yml
included. #455 rewrote those files after this lane branched: it removed
the Hypatia allow-fail steps, made the T1 Guix job blocking and landed the
real Chapel link. This merge carries only the lane's deletion of
boj-build.yml and the FAKE_DATE support in check-allow-fail-expiry.sh. The
lane's dispositions are re-applied to main's workflows in the next commit.

…eproducibility replaces the Guix job
CI-4 ruling (#416, owner 2026-11-05): every allow-fail unit is made
blocking or deleted, never re-dated. After main's #455 there were 9
units left, plus boj-build, which this lane already deleted.
check-allow-fail-expiry.sh as of 2026-12-01 now counts 0.
Made blocking (each was green on main at the time of this change):
- chapel-ci rust-chapel-feature and rust-chapel-real. #455 landed the
real Chapel link; both passed on main (run 42100322359) and on the PR
runs checked up to 2026-11-09. The earlier version of this lane deleted
rust-chapel-real on 2026-11-04 evidence that #455 made stale.
- container-ci tier3-container. All 8 cells passed on main on 2026-11-08
(42453284210), stub-sentinel detection included. It runs weekly and on
dispatch; the head_commit.modified condition, which never matched, is
gone.
- live-provers tier2 provisioning, and tier3 (job and step).
Removed:
- The live-provers tier4 and tier4-gpu jobs. One echoed a TODO; the other
never provisioned GPUVerify or Faial, so neither checked anything.
- The T1 Guix manifest check, retired by the same ruling (the
Containerfile is the reproducibility path).
The Guix check is replaced by a Containerfile reproducibility check in
container-ci, not just dropped:
- container-build and a new container-rebuild build the minimal image on
two independent runners, both with --no-cache --timestamp 0.
- container-reproducible requires the same image ID and lists the layer
digests of both builds when they differ.
- A local podman 4.9 check confirms the mechanism: with --timestamp 0
two builds give one ID, and without it they differ. Whether the full
Containerfile is reproducible is what this PR's container-ci run tests.
- workflow_dispatch is added so the check can be rerun by hand.
Isabelle runs again instead of being skipped:
- scripts/ci/install-isabelle.sh pins Isabelle2025-2 and its SHA-256. It
tries https-only mirrors, release archives (website-<release>/dist/)
first.
- The T2 nightly used the TUM dist/ URL, which redirects to http:// (now
refused) and reset connections. The weekly Isabelle/HOL job used the
Cambridge dist/ URL, which returns 404 since the release was superseded
(job 128978199538, 2026-11-09). Both now call the script.
- verification-proofs-cron gains the script in its path filter, so this
PR runs it.
ProVerif, twelf and the OR-Tools tarball have no package on the runner
image. Each now writes NOT RUN to the step summary rather than passing
silently. Their containerised builds stay covered by tier3-container.
Docs: dated notes in the Chapel rehabilitation decision record and in
docs/handover/{STATE,TODO}.adoc. manifests/live-provers.scm now says it
has no CI consumer.
actions.lock still lists the deleted boj-build.yml. The lock is
tool-owned, so it is refreshed through the official path
(ci:refresh-actions-lock), not edited here.

Container builds are checked for reproducibility, with differences reported when independent builds do not match.
Rust–Chapel checks and supported prover provisioning now block CI when they fail.
Tier 4 and the Tier 1 Guix manifest check have been retired; remaining CI tiers are blocking.
Documentation
Updated CI guidance to reflect the current tier schedule and reproducibility checks.
The pull request adds reproducibility checks for container builds, changes CI job blocking and prover provisioning, and updates related scripts and documentation. It also adds Zig cast-suppression comments and reformats Rust tests without changing their behaviour.
The workflow builds the minimal image twice on independent runners and compares image IDs. On a mismatch, it reports layer differences and, when available, differing filesystem paths. Tier-3 builds now run only on schedule or manual dispatch and are blocking.
Prover provisioning and Isabelle installer scripts/ci/install-isabelle.sh, .github/workflows/live-provers.yml, .github/workflows/verification-proofs-cron.yml
Both workflows use the shared Isabelle installer. Prover provisioning is blocking, and unavailable tools are recorded as not run.
Blocking CI jobs and tier changes .github/workflows/chapel-ci.yml, .github/workflows/boj-build.yml, docs/decisions/2026-05-30-chapel-rehabilitation.adoc, docs/handover/*, manifests/live-provers.scm
Chapel jobs become blocking. The BoJ workflow and quarterly tier-4 jobs are removed. Documentation and manifest comments record the updated CI tiers and reproducibility path.

Explanation
The title names the CI-4 ruling and the two main parts of the change: making allow-fail units blocking or removing them, and replacing the Guix job with a Containerfile reproducibility check. The raw summary and objectives confirm both parts. The title is long (107 characters) and uses internal ticket shorthand, but it still identifies the primary change.
Full details: Description check
Explanation
The description follows the template's main sections: Summary, Changes, and a checked RSR Quality Checklist with Testing notes. It explains the purpose, lists each change by category, and states what was and was not run. Gaps: the Screenshots section is omitted, which is non-critical. Several Required checklist items are ticked with qualifying notes, such as 'Formatting: not applicable', and the author says the full image build and actionlint were not run locally. The 'Tests pass' and 'Linter is clean' items are only partly evidenced, since actionlint could not run. The author also defers the reproducibility result to CI, so that claim remains unverified until the run completes.

…he layer
The first container-reproducible run gave two image IDs. 15 of 16
layers matched, including the echidna binary and z3. Layer 12 differed,
which is the `COPY --from=prover-installer /opt/elan` (the Lean
toolchain). A layer digest does not say which file drifts. I could not
reproduce locally: elan fetches Lean from releases.lean-lang.org, which
this sandbox cannot reach.
Each build job now prints a per-path fingerprint of its image
(scripts/ci/fs-fingerprint.sh, depth 12). The script hashes files
straight from the `podman export` stream, so nothing is extracted. On a
mismatch, container-reproducible reads both build jobs' logs (job-level
`actions: read`) and lists the deepest differing paths
(scripts/ci/fs-fingerprint-drift.sh). No new actions are used, so
actions.lock is unchanged: checkout was already locked for this
workflow.
scripts/ci/test-fs-fingerprint.sh covers identical trees, and content,
mode and link-target changes, each reported at exactly the changed path
and its ancestors. It also covers names with spaces, "|" and "&". It
passes locally. A depth-4 run over /usr/share (19,909 files) took
1m45s. actionlint 1.7.7 and shellcheck are clean, and the SC2015 in the
comparator is fixed.

Results from this PR's own runs, plus the state of each red check.
Containerfile reproducibility: not yet reproducible, and now self-diagnosing.
The first run (4ddfe3f) built the minimal image on two runners with --no-cache --timestamp 0. 15 of the 16 layers were byte-identical, including the echidna binary (layer 10) and z3 (layer 11).
Layer 12 differed: COPY --from=prover-installer /opt/elan, the Lean toolchain that elan installs.
I could not reproduce it locally, because elan downloads Lean from releases.lean-lang.org and this sandbox cannot reach that host.
Each build prints a per-path fingerprint of its image, produced by scripts/ci/fs-fingerprint.sh. It hashes straight from the podman export stream and extracts nothing.
container-reproducible reads both build logs (job-level actions: read) and lists the deepest differing paths, using scripts/ci/fs-fingerprint-drift.sh.
No new actions were added, so actions.lock is unchanged.
Local self-test, actionlint 1.7.7 and shellcheck are all clean.
The next run will name the elan file or files. The fix goes into install-lean.sh once the cause is known.
Isabelle: runs again. On 4ddfe3f the weekly Isabelle/HOL job installed Isabelle2025-2 through scripts/ci/install-isabelle.sh (3m51s), verified its pinned SHA-256, and passed "Verify Isabelle corpus" (job 129201325581).
lint-workflows: the opt-in lock refresh, not the lock gate.
It failed only on the ci:refresh-actions-lock path, which I opened with the label. gh actions-lock cannot resolve hyperpolymath/cicd-suite@4c772eb…, pinned in the untouched zig-ffi-ci.yml.
That repository has been renamed to proven-cicd-and-workflows and has no tags, and the generator needs a tag for a leaf SHA.
The authoritative lock gate passed on the same commit. I have removed the label.
The stale boj-build.yml entry in actions.lock can be refreshed once that upstream publishes a tag. That fix is outside this repository.
rust-ci fmt, Cargo audit and Dependency audit: these also fail on main. I ported the existing fix, #465 (rmcp 3.5 → 3.9 for RUSTSEC-2026-0457/-0461/-0462, plus rustfmt on proof_search.rs), by merge in 4f0a9b5. Locally cargo fmt --check is clean and cargo audit exits 0.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
Renaming rust-chapel-real removes its former allow-fail label from the reported check name. A branch-protection rule that requires the old check name may no longer recognize this job.
Pull requests remain blocked with a pending required check even when the renamed job passes.
This can occur when: A protected branch still requires the previous Rust Build — Real Chapel Library check name, including its allow-fail label.

Inline comments:
Review comments at @.github/workflows/container-ci.yml:
- Line 38: Update both path filters in the workflow to include changes to
fs-fingerprint-drift.sh, and add a CI step that runs the filesystem fingerprint
self-test independently of image ID comparison. Preserve the existing comparison
flow and locate the filters and job steps in the workflow.
Review comments at @.github/workflows/live-provers.yml:
- Around line 343-351: Update the ProVerif installation and live-test flow in
the Tier 3 job, and apply the same change to Twelf and OR-Tools: provide working
provisioning paths and make each live test fail if its required prover is
unavailable, rather than recording NOT RUN or skipping. Ensure a green Tier 3
job confirms all three checks ran.
Review comments at @docs/decisions/2026-05-30-chapel-rehabilitation.adoc:
- Around line 148-152: Mark the CI-flip and Wave-2 guidance in this decision
record as superseded so it no longer presents rust-chapel-real as allow-fail
pending a PIC rebuild. Align those passages with the later static-link update:
rust-chapel-real is blocking, and the PIC rebuild applies to shared-library
output.
Review comments at @docs/handover/STATE.adoc:
- Around line 49-50: Update the Wave-4 and “CI today” sections in the handover
document to reflect the T4 job removal recorded in D5, removing any description
that implies quarterly T4 jobs still exist.
Review comments at @docs/handover/TODO.adoc:
- Around line 158-162: Update the Wave-4 status snapshot to clarify that the 19
Tier-4 backends remain mock-only and that the placeholder job was removed;
remove wording that suggests placeholder checks still exist.
Review comments at @manifests/live-provers.scm:
- Around line 9-13: Update the T4 schedule note in the Tiering block to mark the
quarterly allow-fail schedule as retired, rather than implying those jobs still
run. Leave unrelated manifest and reproducibility notes unchanged.
Review comments at @scripts/ci/check-allow-fail-expiry.sh:
- Line 51: Update the --today handling in the check-allow-fail expiry flow to
reject an explicitly supplied empty value before consulting FAKE_DATE or the
current date; retain the existing fallback behaviour when --today is omitted.
- Line 51: Add regression coverage for `check-allow-fail-expiry.sh` that uses a
dated fixture to verify the result when `FAKE_DATE` is set and `--today` is
omitted, then verify that an explicit `--today` value takes precedence when both
are provided.
Review comments at @scripts/ci/fs-fingerprint.sh:
- Around line 61-67: Update the fingerprint generation and drift-reporting flows
around the awk `split` and `prefix` logic to encode paths containing tabs
consistently, so manifest parsing and grouping preserve each full path without
collisions and reports identify the original path correctly.
- Around line 71-78: Update the AWK fingerprinting flow around flush and cmd so
image paths are passed as data, never interpolated into a shell command; keep
the hashing command fixed and preserve each path alongside its digest in the
fingerprint output, including paths containing dollar signs or quotes.
- Around line 48-56: Update both fingerprint passes and the drift comparison in
the fs-fingerprint flow so link names and targets retain their exact whitespace;
do not reconstruct them by joining fields with single spaces or normalise them
during manifest sorting or comparison. Use a lossless representation throughout
so changes such as repeated spaces produce distinct manifest entries.
Review comments at @scripts/ci/test-fs-fingerprint.sh:
- Around line 25-47: Add tar-based fixtures in the test flow around `fp` that
create identical trees with different ownership or timestamps, and assert their
fingerprints match. Keep the existing `cp -a` checks unchanged so the new cases
independently verify metadata invariance.

What happens instead. The job writes NOT RUN for those three to the step summary and does not report them as passing. Each prover is still built and smoke-tested in its blocking tier3-container cell (Containerfile.wave3, with stub-sentinel detection).
Options for the owner:
(a) Keep NOT RUN and treat tier3-container as the check of record.
(b) Run the live T3 tests for these three inside their wave3 images, so a green job means the check ran.
(c) Fail hard now and accept a red weekly job until (b) exists.
I recommend (b) as the elegant end state, landing (a) now.
This security review couldn’t start because the paying account has exhausted its Codex allowance and has insufficient available credits. The payer can check their balance and add credits in the Codex usage dashboard, then try again. If you do not manage the paying account, contact this repository's admins.
Security. scripts/ci/fs-fingerprint.sh put image paths into a shell
command, the sed in each directory group's hash pipeline. A file named
`a$(touch PWNED)` in an image therefore ran on the runner. The new
self-test shows the old script running it. The script now reads names
and link targets from tar's C-quoted listing, which keeps spaces, tabs,
quotes and newlines as escapes. Content digests are matched to entries
by archive order, and the --to-command never sees a name. Directory
digests are computed over numbered group files, so no path is ever
passed as code.
This also fixes, from the same review:
- hard links ("link to") are parsed apart, not merged into the name;
- whitespace in names and link targets is kept exactly;
- tab names no longer collide.
The self-test adds injection (`$(...)` and backticks), quote, hard-link,
link-target-whitespace and tab cases. It also checks that owners and
mtimes do not change the fingerprint. A run over /usr/share gives the
same 15,728 lines as before, in 60s instead of 105s.
container-ci:
- the path filters now cover every input the Containerfile copies
(build.rs, build_support, crates, benches, src/interfaces) and the
fingerprint drift and test scripts;
- container-build runs the fingerprint self-test on every run.
install-isabelle.sh: each mirror gets a bounded budget
(--connect-timeout 20, --max-time 420, --retry-max-time 420), so a
stalled first mirror cannot use up the job before the fallbacks run.
check-allow-fail-expiry.sh: an explicit empty --today is rejected and
no longer falls back to FAKE_DATE. There is a new regression case in
test-issue-regressions.sh.
Docs: the chapel decision record marks its pre-#455 allow-fail guidance
as superseded. STATE.adoc, TODO.adoc and manifests/live-provers.scm no
longer describe the retired T4 quarterly jobs as running.
Checked locally: test-fs-fingerprint.sh and test-issue-regressions.sh
(mikefarah yq v4.44.6) pass; actionlint 1.7.7 and shellcheck are clean.

(c) Fail hard now and accept a red weekly job until (b) exists.
I recommend (b) as the elegant end state, landing (a) now.

Summary
This PR applies the CI-4 ruling (#416, owner 2026-11-05): every allow-fail unit is made blocking or deleted, never re-dated. The units expire on 2026-11-30, and W0 exit check (8) runs
check-allow-fail-expiry.shas of 2026-12-01. On this branch that check counts 0 units; on main it counts 9.On the T1 Guix job, the owner chose to retire it and add a Containerfile reproducibility check in the same PR, rather than delete it with nothing in its place.
Changes
Made blocking. Each of these was green on main when the change was made.
chapel-cirust-chapel-featureandrust-chapel-real. audit: routing/rule-engine recon, Logtalk quarantine; Agda proofs re-checked under PROOF-POLICY §2.1 #455 landed the real Chapel link. Both passed on main (run 42100322359) and on the PR runs checked. The first version of this lane deletedrust-chapel-realon evidence from 2026-11-04 that audit: routing/rule-engine recon, Logtalk quarantine; Agda proofs re-checked under PROOF-POLICY §2.1 #455 made stale.container-citier3-container. All 8 cells passed on main on 2026-11-08 (run 42453284210), stub-sentinel detection included. It now runs weekly and on dispatch. I dropped itshead_commit.modifiedcondition, which never matched.live-proverstier-2 provisioning, and tier 3 (job and step).Removed.
tier4andtier4-gpu. One only echoed a TODO, and the other never provisioned GPUVerify or Faial.boj-build.yml. It failed on every push to main: it was plainhttptoboj-server.local, with a malformed JSON body.The Guix check is replaced by a reproducibility check.
container-buildand a newcontainer-rebuildbuild the minimal image on two independent runners, both with--no-cache --timestamp 0.container-reproduciblerequires the same image ID. If the IDs differ, it lists both builds' layer digests so the drifting layer can be found.--timestamp 0, two builds give the same ID, and without it they differ.container-cirun tests. I'll report the result here.Isabelle runs again instead of being skipped.
scripts/ci/install-isabelle.shpins Isabelle2025-2 and its SHA-256. It tries https-only mirrors, release archives (website-<release>/dist/) first.dist/URL redirected tohttp://and reset connections.dist/URL returns 404 because the release was superseded (job 128978199538). That is one of the reds on main.NOT RUN is recorded, not hidden. ProVerif, twelf and the OR-Tools tarball are unavailable on the runner image. Each writes NOT RUN to the step summary. Their containerised builds stay covered by
tier3-container.Docs.
docs/handover/{STATE,TODO}.adoc.manifests/live-provers.scmnow says it has no CI consumer.actions.lock. It still lists the deletedboj-build.yml. The lock is tool-owned, so I'm refreshing it through theci:refresh-actions-locklabel, not by hand.History. This branch merges main instead of rebasing. The merge commit takes main's version of each workflow. The second commit applies the dispositions to main's text.
