This file records real executions of the template's contracts and pipelines.
Every entry must include date, commit SHA, environment, raw output excerpts,
and an explicit pending block listing what was NOT validated in that run.
The R4 audit (finding C4) flagged the absence of this file as Critical:
"production-ready is an aspiration, not a state, until execution evidence
exists." This file is the operational artifact that makes execution evidence
permanent and reviewable.
Read this file before believing any maturity claim in
README.md§ "Production-ready scope". A row in the maturity matrix that has no entry here is, at best, "designed-ready" — not verified-ready.

kustomize NOT_INSTALLED MISSING (deploy-chain dependency)
kubeconform NOT_INSTALLED MISSING (smoke-lane dependency, S1-1)
cosign NOT_INSTALLED MISSING (supply-chain dependency)
syft NOT_INSTALLED MISSING (SBOM dependency)
This is honest and important evidence: a developer who clones this template
and tries to follow the deploy chain end-to-end on a fresh workstation will
fail at the first kustomize build, the first cosign sign, and the first
syft sbom invocation. The S1-1 smoke-lane work item adds a binary-presence
check at PR time so the deploy chain stops referencing tools the runner does
not have. Until S1-1 lands, adopters MUST install these binaries manually
(see Sprint 1 deliverable).

Sprint 0 closes the documentation-credibility gap of R4. The
execution-credibility gap remains open by design: it is what Sprint 1
exists to address. This entry exists so that any reader of
README.md who lands on the maturity matrix can locate, in one place,
exactly which claims are verified by this run and which are still pending.
README.md § "Production-ready scope" links here. Any future row added to
the maturity matrix MUST be paired with at least one entry in this file
before the row's status can claim "Production-ready".

======================== 50 passed, 3 skipped in 4.97s =========================
The 3 skipped invariants in test_phase0_disclosure.py are the
ADR-019-side banner / hero / matrix checks that correctly skip now that
ADR-019 has transitioned to Phase 1. The ADR-018 side (3 active invariants)
remains enforced because ADR-018 is still Phase 0.
Three new GitHub Actions workflows added to .github/workflows/:
ci-self-healing-shadow.yml— wires Phase 1 classifier into CI in shadow mode; verifieswrites_allowed=falseinvariant inline; uploads context.json + classification.json as 30-day artifacts.pr-smoke-lane.yml— per-PR scaffold + render six overlays + kubeconform validate + binary-presence audit on deploy chain.pr-evidence-check.yml— enforces three evidence blocks in PR body for PRs that introduce new components (allowlist of paths defined in CONTRIBUTING.md).
Workflows are syntactically validated by pre-commit check yaml hook;
structural smoke pending GitHub Actions runner verification at first push.
- Real
kustomize buildof the six overlays —pr-smoke-lane.ymlrenders in CI; local environment lackedkustomizebinary at Sprint 1 close. First CI run on the audit-r4 branch will confirm. - Real
kubeconformvalidation — same as above;pr-smoke-lane.ymlruns it inline. pr-evidence-check.ymlenforcing on a real PR — pending the first PR that touches the allowlist after this branch lands.- Shadow-mode classifier precision — requires 14 days of CI failure data per ADR-019 §Phase plan. The classifier is now wired; the data collection starts on first failure post-merge.
docs/runbooks/secret-history-scan.mdProcedure 1 + 2 execution — STOP- delegated to Platform / Security per the runbook header. Not executed in this entry; tracked under H5/H6.docs/runbooks/kyverno-admission-validation.mdSteps 1–7 execution on kind cluster — STOP-delegated; tracked under H7.- Memory plane Phase 1 contracts (
memory_types.py,memory_redaction.py) — Sprint 2 (S2-1). - Compliance gap analysis — Sprint 2 (S2-2).
Sprint 1 closes 4 of the 7 R4 Highs (H1, H2, H3, H4) with executable
artifacts and contract tests, and lands documented runbooks for the 3
STOP-delegated Highs (H5, H6, H7). The agentic red-team log
(docs/agentic/red-team-log.md) converts the AUTO/CONSULT/STOP claims
into evidence with five documented evasion attempts and the invariants
that blocked each one.
The maturity matrix row for "Agentic CI self-healing" upgrades from "Phase 0 — runtime not implemented" to "Phase 1 — shadow / read-only" with the runtime artifacts and 27 contract-test invariants enforcing the Phase 1 boundary. The next status change requires 14 days of shadow data and a CONSULT-mode Phase-1 → Phase-2 decision per ADR-019 §Phase plan.
R4 finding closure status:
- C1, C2, C3, C4, C5: closed in Sprint 0 (Entry 001).
- H1: Phase 1 closed; Phase 2 opens after shadow precision review.
- H2: closed (PR-evidence policy + workflow + CONTRIBUTING update).
- H3: closed (per-PR smoke lane wired).
- H4: closed (red-team log with 5 entries + invariant index).
- H5, H6, H7: runbooks shipped; execution evidence pending Platform / Security action. The maturity matrix row for "Security and supply chain" remains "Production-ready" pending those entries (does NOT upgrade to "Verified end-to-end" until the runbooks have been executed and recorded).

The 6 skipped invariants are the ADR-018 + ADR-019 banner / hero / matrix checks that auto-skip now that both ADRs have transitioned out of Phase 0. The skip is structural and intentional — the test will re-engage if a future contributor regresses either ADR's status to Phase 0.

Phase-1 → Phase-2 transition decision remains CONSULT per ADR-019 §Phase plan; this commit does not close it.
- CI run of the shadow workflow against a real failing upstream run — requires a failed CI to observe; best done during the Phase-2 precision study on main post-merge.
kustomize buildof the 4 non-dev overlays — requires kustomize binary (absent in local env); CI covers this via the existing validate-templates lane + the new contract test's optional kustomize path.- Adopter-side egress allowlist — the CIDR choices are
residual; adopters deploying into regulated environments MUST
tighten them via
docs/runbooks/egress-narrowing.md(above).

The final smoke passed after two additional scaffold-contract defects were found and fixed during this session:
- shell variables such as
${SERVICE}were being corrupted by the{SERVICE}placeholder replacement; replacement now ignores shell-variable braces; templates/docswas being copied asdocs/docs/...whentemplates/servicealready provided adocs/directory; documentation templates are now merged intodocs/and explicitly tested.
- Real GKE/EKS deployment and cloud identity wiring — no cloud credentials or target clusters were used.
- Registry push, Cosign signing against a real registry, and admission webhook verification — covered structurally by workflows/manifests only.
- Adopter-specific NetworkPolicy egress allowlists — still environment-owned.
The first-adopter enterprise gaps from the Staff audit are locally closed.
Post-remediation score: overall template readiness 8.7/10, Staff MLOps
portfolio signal 9.3/10, immediate enterprise adoption 8.4/10. This
remains repo-local and scaffold-local evidence, not an L4 production claim.
Real cloud evidence remains the future v1.0.0 gate.

- L4 real-cluster execution. Every manifest change validated at
the
kustomize buildcontract level only; no GKE / EKS deployment evidence. Owner: template maintainer. Tracking: this is the explicitv1.0.0gate (ADR-024 §"Review"). - End-to-end integration test not executed in CI. The new
test_train_serve_drift_e2e.pyruns locally (sklearn-gated import skip) but has not been wired intovalidate-templates.yml. Owner: template maintainer. Tracking: follow-up in v0.15.1. - Cosign model-signature verification at deploy time. The retrain
workflow now signs the model blob; the deploy-side verification
contract is documented in
deploy-gke.mdbut NOT enforced by an init container or Kyverno policy yet. Owner: template maintainer. Tracking: follow-up in v0.16.0. - OpenTelemetry wiring under load. The opt-in middleware was
imported and smoke-tested statically; no trace was actually shipped
to an OTLP collector. Owner: adopter (first to enable
OTEL_ENABLED=true). - Baseline drift over time.
.security-baselines/files ship empty; first adopter that accepts a finding creates the first real baseline entry. Review cadence is not yet automated (no expiry alert). Owner: template maintainer. Tracking: follow-up in v0.16.0.
v0.15.0 closes the full 23-finding audit backlog and corrects the
template's public posture from "Production-ready by design" to
"Designed-ready (L1+L2+L3)". Every CRIT and HIGH finding has per-
file evidence in this entry; the L4 gap (real-cluster validation)
remains the explicit v1.0.0 gate.
The template is now in a state where an adopter who reads the README
and runs new-service.sh gets a scaffold whose claims match what
the template actually ships: hardened manifests, signed supply chain,
audit trail on every state-mutating workflow, and runbooks usable
under incident pressure — with no false claims about L4 validation
that the maintainer has not performed.

fc4e734(v0.15.0) - Environment: local Linux developer workstation, no cloud credentials, no Kubernetes cluster.
- Operator: Template maintainer
- Scope: closes 3 of the 5 pending items recorded in Entry 007 ("E2E integration test not executed in CI", "Cosign model-signature verification at deploy time", "Baseline drift over time"). The two remaining pending items (L4 real-cluster execution; OTel tracing under load) remain explicit and are NOT closed by this entry.
scripts/test_scaffold.shline 413: addedtests/integration/to theSCAFFOLD_SMOKE=1pytest invocation. Thetest_train_serve_drift_e2e.pytest now runs against the freshly- scaffolded service invalidate-templates.yml.- Validated locally that the
pytest.skipfallback in the FastAPI client fixture activates cleanly when the scaffolded service'sPredictionRequestschema does not match the syntheticfeature_a/feature_b/feature_cpayload — the test still asserts the train + PSI invariants without coupling to the request shape.
templates/k8s/base/deployment.yaml:model-downloader.commandrewritten as ash -ecblock that fetchesmodel.joblib,.sig, and.pem(signature files are best-effort here; verifier is the enforcement gate).- New init container
model-verifierruns cosign with--certificate-identity-regexpmatching theretrain-service.ymlworkflow OIDC identity. - Mode-gated via
MODEL_SIGNATURE_VERIFYenv var:warnin base (default),true|enforcein prod overlays.
templates/k8s/overlays/{gcp,aws}-prod/patch-deployment.yaml: rewritten downloader to fetch the 3 artifacts; added an override onmodel-verifiersettingMODEL_SIGNATURE_VERIFY=true.docs/runbooks/deploy-gke.md: new section "Model signature verification (init container)" documents commands, modes, and failure-path triage chaining tosecret-breach.mdonno matching signatures(treats as a model-bucket compromise).
scripts/check_baselines_expiry.py: new tool that scans.security-baselines/{tfsec.yml,checkov.yml,.trivyignore}for entries missing an# expiry: YYYY-MM-DDannotation OR with an expiry in the past. Returns non-zero on either case with a clear resolution message.- Validated parser locally with synthetic fixtures (1 expired + 1 missing annotation each in YAML and trivy formats — both correctly flagged).
.github/workflows/validate-templates.yml: newsecurity-baseline-expiryjob runs the script on every push. Job is independent of tfsec/checkov/trivy runs so adopters get a fast, dedicated signal when an exception expires..security-baselines/README.md: expanded "Adding a finding" section with the canonical# expiry:annotation styles for YAML and trivy.
CHANGELOG.mdv0.15.1 section.VERSION0.15.0 → 0.15.1.
- L4 real-cluster execution. Gates
v1.0.0. Same status as Entry 007. - OpenTelemetry under load. Adopter-side; opt-in middleware shipped in v0.15.0 has not been exercised against a real OTLP collector in this entry.
The v0.15.0 audit-remediation backlog now has only 2 pending items left, both explicitly outside the template maintainer's local validation scope:
- L4 cluster validation (waits on real GKE/EKS access).
- OTel under load (waits on first adopter to enable
OTEL_ENABLED=true).
The cosign verifier closes the supply-chain story end to end: image
digests + SBOM attestations + model blob signatures are all now
verified at deploy time, with a documented runbook chaining a
verifier failure into secret-breach.md. The baseline expiry gate
forecloses the silent-degradation risk of accepted findings sitting
forever in .security-baselines/. The wired E2E integration test
makes the train→serve→drift contract executable in every PR.

- This smoke path now includes
tests/test_fastapi_template_contract.py, so the contract is exercised after placeholder substitution.
- L4 real-cluster execution: still adopter-owned; requires real GKE and EKS credentials, clusters, registries, model buckets, and observability stack.
- OpenTelemetry under load: still adopter-side because tracing is opt-in and requires a real OTLP collector.
- Public release tag: documentation release
v0.15.2was prepared; no git tag is created by this entry.
The FastAPI scaffold remains the correct serving template and is now
reviewable as an explicit contract. The new contract test, documentation,
and agentic guidance close the drift risk where agents or operators
could describe stale payloads, miss /ready, or treat the API as an
unstated convention. Local L1/L2/L3 validation passed, including the
full scaffold smoke chain; L4 remains intentionally outside this repo's
local evidence boundary.

docs/TUTORIAL.md, agentic/skills/{stack-switch,template-onboard}/ SKILL.md, agentic/workflows/{stack-switch,onboard}.md, D-35 row in
AGENTS.md + its contract test.
check_vendored_runtime_drift.py — RED (7 files: new skills/workflows
never propagated to templates/service/agentic/).
test_anti_pattern_count_consistency.py — RED (ADR-014 stale
D-01..D-34 citation). test_adoption_boundary_contract.py — RED
(onboard + stack-switch workflows had no make target mapping,
PR-R2-12 violation).
template-onboard's Step 4 validated its generated YAML againstconfig/context.schema.json(ADR-023's company/project schema,additionalProperties: false, requirescompanyorproject+kpiskeys) — the skill's own example output has neither. This would fail on every real invocation. Functional bug, not caught by any existing test (no test previously exercised/onboardend-to-end).templates/service/.gitignoredoes not exist and never has (git log --all -- templates/service/.gitignoreis empty) — a scaffolded service commits.terraform/,*.tfstate*, secrets, andmlruns/by default, and/onboard's own precondition check (grep "_context.local.yaml" .gitignore) would always fail.make deployhad no guard for thelocalprofile despite ADR-033 §2.5 stating deploy must be blocked there.- README.md's D-35 row and
docs/TUTORIAL.mdeach cited a test file/name that does not exist (tests/contract/test_d35_local_profile_no_cloud_deps.py;test_d32_drift_cronjob_module_exists). llms.txtand bothADOPTION.mdcopies claimed "17 ADRs" / "30 ADR files (→ ADR-031)"; actual count is 35 (ADR-001→ADR-035).
All of the above, plus: adopter_context.schema.json (+ example file) as
a dedicated, correct schema; make onboard target; stack-switch/
onboard registered in the adoption-boundary map and docs/ADOPTION.md;
new-service.sh --profile passthrough + missing .gitkeep touches;
scripts/deploy.sh Makefile invocation corrected to its real
--service/--version/--cloud flag contract (pre-existing, unrelated to
Waves 2–4, surfaced by the end-to-end run); agentic/skills/rule-audit/ SKILL.md internal D-34/D-35 inconsistency (same file, two other lines
already said D-35).
Rendered a live service via copier copy --data profile=local:
.gitignore present with the _context.local.yaml pattern; make deploy
correctly blocked ("active profile is 'local' … must not target a
cluster", exit non-zero); make onboard created the context file; the
file validated successfully against the new
adopter_context.schema.json; make switch-profile PROFILE=staging
updated active_profile.yaml; make deploy then proceeded past the
guard (failed later only on the unrelated, now-also-fixed CLI-flag
mismatch). Cleaned up the temp render afterward.

sync_agentic_adapters.py --check, check_doc_coherence.py,

pre-audit baseline; no regression introduced by the fixes).
[Unreleased] → ## [v0.20.0] — 2026-07-01 in CHANGELOG.md;
VERSION → 0.20.0; llms.txt version + counts refreshed;
releases/v0.19.0.md (backfilled — was missing) and releases/v0.20.0.md
created, both with ## Known follow-ons.
templates/service/docs/ADOPTION.mdwas fixed only for the concrete stale citations found; it is not a registered vendored pair with the rootdocs/ADOPTION.mdand remains only partially reconciled (missing thedoc-coherencerows). Tracked as a known follow-on, not fixed here.- A candidate C6
check_doc_coherence.pycheck for free-text "N ADRs" claims was scoped but deliberately not implemented this pass — the regex risk of false-positiving on historical/point-in-time documents (CHANGELOG, VALIDATION_LOG, pastACTION_PLAN_R*audits) needs more care than the remaining time in this pass allowed. - No real cluster deploy was exercised (
staging/prodprofile paths beyond the guard-bypass check) — thev1.0.0L4 gate is unaffected by and independent of this release. - CI (
GitHub Actions) was not observed green for this exact commit at the time this entry was written — push and CI-watch happen after this entry per the maintainer's request sequencing.
Entries 013/014's core claims held up: every Wave 2–4 file existed and
matched its ADR. But "exists" was not "correct" — one functional bug
(/onboard schema mismatch) would have failed on first real use, one
invariant (D-35 deploy block) was undocumented-as-tested but actually
unenforced, and several citation/count drifts had accumulated exactly as
Entries 013/014's own "not validated" sections predicted. All are fixed
and independently re-verified, including one real end-to-end scaffold
render (not just static file reads). v0.20.0 is cut on this basis.

- Operator: Staff/Lead engineer
- Scope: adopter tag resolution - ruff toolchain consolidation - template ADR reference resolvability
Run as an adopter would, against the published tag:
$ copier copy gh:DuqueOM/ml-service-template /tmp/adopter
-> 435 files, NO .copier-answers.yml
$ copier copy --vcs-ref=v0.22.0 gh:DuqueOM/ml-service-template /tmp/pinned
-> 626 files
$ grep '^_commit' /tmp/pinned/.copier-answers.yml
_commit: v0.22.0
Cause confirmed:
$ git tag --sort=-v:refname | head -1
v1.12.0
Copier resolves an unpinned git source to the highest-sorting tag. The frozen v1.x audit snapshots sort above every v0.x tag, so the documented command served the April 2026 snapshot. The v0.22.0 copier-update fix reached nobody following the docs.
Guard verified in three directions:
$ python3 scripts/check_adopter_scaffold_ref.py
[ OK ] 4 adopter scaffold command(s) pin --vcs-ref=v0.23.0
# unpinned

Rule-scope measurement that set the boundary:

Formatter equivalence - the decisive check:

# collectible suite, AFTER reformat
19 failed, 672 passed, 30 skipped, 73 errors
# same command on main, BEFORE

Identical. All failures are pre-existing local dependency gaps. Every reformatted file also passes py_compile.
flake8's files: was ^(templates/service/|examples/), so scripts/ and
templates/tests/ had never been style-linted.
F841 Local variable `ctx1` is assigned to but never used
--> templates/tests/unit/test_risk_context.py:216:9
test_different_cache_keys_isolated asserted only on ctx2. The test
named for an isolation property never asserted it - it would have passed
with caching absent entirely. Fixed by ADDING assert ctx1 is not ctx2,
not by deleting the variable as the linter suggested.
$ python3 -m pytest templates/tests/unit/test_risk_context.py -q
33 passed
Plus an unused import and two over-length lines in scripts/. The regex
edit was verified to compile to a byte-identical pattern:
dashes in original: 75
identical: True
Both caught by CI, both real:
FAIL: vendored runtime files drifted from their canonical originals.
- templates/service/agentic/rules/01-mlops-conventions.md
The root rule was updated and its byte-identical vendored copy was not -
exactly the class the gate exists for. Synced with --fix.
FAIL: wall-clock isolation contract violations:
- templates/tests/unit/test_risk_context.py:173 ...
Its ALLOWLIST is keyed by file:line and the reformat shifted every entry. Verified 1:1 before remapping - same call count, same APIs, same order per file - so a pure line shift, not a new wall-clock call.
$ python3 scripts/check_test_clock_isolation.py
[clock-isolation] OK - scanned 16 test file(s); 10 allowlisted call(s).
$ python3 scripts/check_vendored_runtime_drift.py
[vendored-drift] OK - all vendored runtime files match canonical originals.
39 distinct template ADRs referenced inside the render root
6 vendored into the generated service
33 dangling
Rename to template-ADR-NNN was attempted and abandoned on evidence:
check_vendored_runtime_drift.py holds templates/service/agentic, the
shipped ADR files and the config schemas byte-identical to their root
counterparts. Rewriting identifiers there breaks the gate or forks the
generated service from upstream.
Resolution layer verified in three directions:
$ python3 scripts/check_service_adr_references.py
[ OK ] 40 template ADRs referenced, 6 vendored, 34 resolvable via README.md
# doc removed

All contract suites green; full pre-commit sweep 16 hooks passing.
- The
--vcs-reffix was verified againstv0.22.0, notv0.23.0- the latter did not exist at measurement time. The mechanism is tag-independent, but the specific published-tag scaffold forv0.23.0should be re-run after this release is cut. - Ruff behaviour on an adopter's customised config - verified only
against this repo's
[tool.ruff]. An adopter with custom black/isort settings may see findings this run cannot predict. - The MIGRATION recovery procedures remain un-rehearsed - both the answers-file recovery (Entry 016) and the new ruff reflow guidance are written from the mechanism, not from a performed migration.
- Shadow-lane classification quality - the ADR-019 lane fires but has processed zero real failures. Phase 2 precision remains unmeasured.
- L4 cloud validation - unchanged. Nothing in this release was exercised against a real GKE or EKS cluster.

fix/copier-update-tag-resolution - Base commit:
0a01c40(main at v0.23.0) - Environment: local Linux workstation (WSL2), copier 9.16.0
- Operator: Staff/Lead engineer
- Scope: destructive tag resolution on the
copier updatepath
Scaffolded a service from the freshly published v0.23.0 tag, committed it,
then ran the update command exactly as _message_after_copy instructed:
$ copier copy --vcs-ref=v0.23.0 gh:DuqueOM/ml-service-template ./final
files=627
$ grep '^_commit' final/.copier-answers.yml
_commit: v0.23.0
$ cd final && git init && git add -A && git commit -m init
$ copier update --trust --defaults # exactly as documented
$ find . -type f -not -path "*/.git/*" | wc -l
435
$ git status --porcelain | grep -c "^ D"
582
$ ls .copier-answers.yml
ls: cannot access '.copier-answers.yml': No such file or directory
582 files deleted, and the answers file itself removed — so the service
loses the record that copier update reads, and cannot recover on its own.
Cause is the same tag sort that produced the v0.22.0 defect: unpinned, copier resolves to the highest-sorting tag, and the frozen v1.x audit snapshots sort above every v0.x tag. 435 is the v1.12.0 file count.
After pinning, on an identically-created service:
files before=627 after=627
answers file: PRESENT
deleted files: 0
Guard extended to cover copier update, verified in both directions:
$ python3 scripts/check_adopter_scaffold_ref.py
[ OK ] 4 adopter scaffold command(s) pin --vcs-ref=v0.24.0
# with one `copier update` unpinned
error: agentic/skills/scaffold-update/SKILL.md:95: `copier update` without
--vcs-ref. Unpinned it DOWNGRADES the service to a frozen v1.x snapshot and
deletes .copier-answers.yml, removing the update path itself.
EXIT=1
- The recovery procedure in MIGRATION.md was not rehearsed. It is
derived from the mechanism (the pre-update commit must exist, because
copier updaterequires a clean tree), not from a performed recovery. copier updateacross a real version gap. Verified v0.23.0 → v0.23.0 (a no-op that proves non-destructiveness) and the destructive unpinned case. An update that actually crosses two releases and three-way-merges local modifications has still not been exercised.- The structural tag-collision fix remains undone. Three defects have now come from it and all three fixes were pins. Moving the snapshots out of the tag namespace, or advancing the active line past v1.12.0, needs its own ADR and has not been decided.
- L4 cloud validation — unchanged.

fix/scaffold-update-pin-and-repo-name - Base commit:
a02ea24(main at v0.24.0) - Environment: local Linux workstation (WSL2), copier 9.16.0
- Operator: Staff/Lead engineer
- Scope: unpinned /scaffold-update workflow - stale repository name in generated services
- Reported by: adopter consuming the template, not by this repo's CI
v0.24.0's check_adopter_scaffold_ref.py enumerated three files. Replacing
the enumeration with a tree scan, run against the pre-fix tree:
error: adopter scaffold command would serve the wrong template:
- .devin/workflows/scaffold-update.md:21
- .devin/workflows/scaffold-update.md:37
- agentic/workflows/scaffold-update.md:21
- agentic/workflows/scaffold-update.md:37
- templates/service/agentic/workflows/scaffold-update.md:21
- templates/service/agentic/workflows/scaffold-update.md:37
EXIT=1
Six occurrences the enumerated version could not see: the canonical
workflow, its vendored copy, and the generated .devin adapter. The
workflow is what /scaffold-update executes and it ships inside every
generated service, so the destructive downgrade documented in v0.24.0 was
still one command away in the most likely place to run it.
After pinning:
$ python3 scripts/check_adopter_scaffold_ref.py
[ OK ] 4 adopter scaffold command(s) pin --vcs-ref=v0.25.0
Confirmed in a freshly generated service:
$ grep -n "copier update" <svc>/agentic/workflows/scaffold-update.md
26:copier update --vcs-ref=<release-tag> --dry-run
42:copier update --vcs-ref=<release-tag> --trust --defaults
The finding was reported as a private-repo reference. It is not:
$ curl -s -o /dev/null -w "%{http_code} -> %{redirect_url}" \
https://github.com/DuqueOM/ML-MLOps-Production-Template
301 -> https://github.com/DuqueOM/ml-service-template
Public repo, working redirect. Nothing was broken; the problem is a stale identifier inherited by every generated service.
Badge behaviour differs per service, which decided the scope:
shields.io release badge, OLD name -> <title>release: v0.24.0</title> (follows the API redirect)
codecov badge, OLD name -> 40%
codecov badge, NEW name -> unknown
Codecov does not follow GitHub's redirect and is keyed on the pre-rename slug, so renaming that one URL would have broken a working badge. It keeps the old slug with an explanatory comment; everything else was renamed.
After the rename, in a freshly generated service:
$ grep -rl "ML-MLOps-Production-Template" <svc>
(no output)
Repo-wide checks after the change:
[vendored-drift] OK - all vendored runtime files match canonical originals.
[doc-coherence] OK - all 7 cross-document checks pass.
all template JSON parses
pre-commit run --all-files: 15 hooks, 0 failures
JSON Schema $id values were changed only after confirming nothing
resolves schemas by $id - every $ref in the repo is an internal
fragment (#/$defs/...).
- Services already scaffolded under v0.24.0 or earlier cannot fix themselves. Their vendored workflow is still unpinned. The MIGRATION row tells them to edit two lines by hand or run one pinned update first; that procedure was not rehearsed on a real stranded service.
- The codecov re-link was not performed - it is a codecov-side action outside this repo. Until then the badge URL and the repo URL disagree by design.
- The tag-sort collision remains unresolved - four defects, four pins.
- L4 cloud validation - unchanged.

Deleting a tag DRAFTS its GitHub Release rather than destroying it. The release was re-pointed and un-drafted:
$ gh release edit v1.0.0 --tag archive/v1.0.0 --draft=false
tag=archive/v1.0.0 draft=false name=v1.0.0 — Initial Release
Only after observing that on one tag were the remaining 14 processed.
