feat(scripts/ops): Cloudflare DNS e2e-record prune tool + recurrence fix
Adds
scripts/ops/prune_cf_e2e_dns.sh, the targeted immediate-unblock tool for the recurring CF error 81045 (DNS record quota exhausted by leaking e2e-smoke-* / e2e-tmpl-* records), and wires a durable post-run prune step into the e2e-staging-saas workflow.root-cause
Staging E2E harnesses (
tests/e2e/test_staging_full_saas.sh,tests/e2e/test_template_delivery_e2e.sh) create DNS records for disposable org slugs likee2e-smoke-<date>-<run>-<uuid>ande2e-tmpl-<rand>. When teardown is skipped — CI cancellation, runner crash, transient CP/AWS error, or a missed bash trap — those records leak. Cloudflare caps records per zone; once the cap is hit, new tenant provisioning fails with CF code 81045. The existingsweep-cf-orphans.sh(#3139) correlates DNS records against live orgs/workspaces and is the right general sweeper, but it needs live CP + AWS state and is not scoped to catch every short-lived e2e smoke record. This PR provides a focused, pattern+age-based pruner plus a workflow recurrence so the quota blocker does not recur.no-backwards-compat
No backwards-compatibility concerns. The script is a new ops janitor; the workflow only adds a best-effort post-run cleanup job. Existing callers are unaffected. The workflow job uses
continue-on-error: trueso a transient CF API issue cannot block merge.comprehensive-testing
tests/ops/test_prune_cf_e2e_dns_fail_closed.sh(new) covers:bash tests/ops/test_prune_cf_e2e_dns_fail_closed.sh→ 6/6 pass.local-postgres-e2e
Not applicable. This script operates against the Cloudflare DNS API only; it does not touch Postgres, workspace-server handlers, or local e2e fixtures.

It uses--apply --min-age-hours 2and only fires whenCF_STAGING_DNS_API_TOKENandCF_STAGING_ZONE_IDsecrets are configured. The script's own--min-age-hoursdefault is 24 for standalone use; the workflow uses a tighter 2-hour threshold because e2e-smoke records are short-lived.five-axis-review

Reviewed the fail-closed patterns from
sweep-aws-secrets.sh(#3134) andsweep-cf-orphans.sh(#3139). This tool is intentionally complementary to #3139: #3139 sweeps orphan records by correlating with live CP orgs + EC2; this pruner targets the disposable e2e-smoke/e2e-tmpl records by pattern and age, independent of CP state, and adds scheduled recurrence.relation to #3139

Harden the Cloudflare DNS e2e-record prune tool and land the durable recurrence fix together: - scripts/ops/prune_cf_e2e_dns.sh: * URL-aware curl mock style, CF token/zone preflight validation. * Dry-run by default; requires --apply / PRUNE_APPLY=1. * --min-age-hours arg + PRUNE_MIN_AGE_HOURS env. * MAX_DELETE_PCT safety gate (default 50) refusing runaway deletes. * CF_API_TOKEN/CLOUDFLARE_API_TOKEN and CF_ZONE_ID/CLOUDFLARE_ZONE_ID fallback aliases. * Paginates DNS list API, aborts on non-2xx / malformed JSON. - .gitea/workflows/e2e-staging-saas.yml: * Add prune-stale-e2e-dns post-run job after e2e-staging-saas. * Runs always(), gated on CF_STAGING_DNS_API_TOKEN + CF_STAGING_ZONE_ID secrets, --apply --min-age-hours 2. * Best-effort (continue-on-error) so CF blips don't block merge. - tests/ops/test_prune_cf_e2e_dns_fail_closed.sh: * Boundary test proving abort on non-2xx / malformed / non-array CF list. * Sentinel proving delete step is NOT reached in abort cases. * Proves young / non-ephemeral records are kept. * Happy-path control proving old e2e-smoke record reaches delete. Local tests: bash tests/ops/test_prune_cf_e2e_dns_fail_closed.sh # 6/6 pass Relates-to: #3139 (sweep-cf-orphans is the orphan-based general sweeper; this is the targeted e2e-test-record pruner + scheduled recurrence fix; complementary, not redundant). 🤖 Generated with [Claude Code](https://claude.com/claude-code)REQUEST_CHANGES — safety-critical review for #3140 @
027c057f.Blocking issues:
Name filter is wider than the stated e2e-smoke-* / e2e-tmpl-* scope. scripts/ops/prune_cf_e2e_dns.sh builds EPHEMERAL_RE as
^(e2e-smoke|e2e-tmpl)[a-zA-Z0-9_-]*\.<zone>$, which matches names without the required hyphen, e.g.e2e-smokeprod.moleculesai.appore2e-tmplprod.moleculesai.app. For an automatic --apply Cloudflare DNS deleter, this must require the disposable prefixes exactly (e2e-smoke-*ande2e-tmpl-*) and have regression coverage proving near-miss names are kept.The PR currently fails lint-continue-on-error-tracking. Exact error:
.gitea/workflows/e2e-staging-saas.yml,line=382: jobprune-stale-e2e-dnshascontinue-on-error: truewith no# mc#NNNNor# internal#NNNNtracker comment within 2 lines. Best-effort cleanup can be continue-on-error, but the required tracking lint must pass.The PR currently fails lint-required-context-exists-in-bp. Exact error: new emissions
E2E Staging SaaS (full lifecycle) / Prune stale e2e DNS records (pull_request)and(push)have no directive comment. Add# bp-required: yesor# bp-required: pending #NNNdirectly above the job as required by the lint. Since this cleanup job is intended non-required/best-effort, the directive should make that asymmetry explicit per policy.The fail-closed shape is otherwise on the right track: CF token/zone preflight exists, DNS list uses curl -f plus JSON/result validation, pagination is explicit, dry-run is default, secrets are referenced through CF_STAGING_DNS_API_TOKEN/CF_STAGING_ZONE_ID, and the test uses a delete sentinel rather than only checking exit code. But the automatic --apply blast radius needs the prefix bug fixed before approval.
REQUEST_CHANGES after current-head safety review of
027c057f.Correctness / robustness:
prune-stale-e2e-dnsjob that emits newpull_requestandpushcontexts with no branch-protection directive. CI is already red inlint-required-context-exists-in-bpfor this exact context, so I cannot confirm thecontinue-on-errorprune job is non-required. Either gate it to the intended events or add the required bp directive/tracker so policy can prove it is non-required before this auto-apply job lands.continue-on-error: truewithout the required mc/internal tracker comment. CI is red inlint-continue-on-error-trackingfor this line.PRUNE_ZONE_DOMAIN, while scripts/ops/prune_cf_e2e_dns.sh:48 defaults tomoleculesai.app. The matcher is anchored to that domain, so observed leaked records likee2e-smoke-...staging.moleculesai.app/e2e-tmpl-...staging.moleculesai.appwill not match. That makes the scheduled --apply prune likely ineffective for the quota failure it is meant to clear. Please pass/derive the staging zone domain and add a regression case for staging names.Security / blast radius:
--apply, uses CF secrets from workflow refs, and the local fail-closed test passes 6/6. The bad CF list cases do assert the delete sentinel stays absent, so the abort-before-delete boundary is covered.Performance/readability: no separate concerns beyond the correctness/policy blockers above.
1. Tighten EPHEMERAL_RE to require the trailing hyphen: Prevents matching e2e-smokeprod / e2e-tmplprod near-miss names. 2. .gitea/workflows/e2e-staging-saas.yml: * Add directive above the job. * Add tracker comment for . * Pass so the scheduled prune matches actual staging subdomain records. 3. tests/ops/test_prune_cf_e2e_dns_fail_closed.sh: * Add near-miss regression cases (e2e-smokeprod, e2e-tmplprod kept). * Add staging subdomain happy-path case. * make_list() now accepts zone domain parameter.

The remaining staging E2E red is the live CF quota condition this PR is intended to clear, not a code regression.Minor non-blocking note: the PR body still has a stale local-test count/older regex wording in narrative text, but the code, tests, and current CI reflect the corrected behavior.
