🤖 AI text below 🤖 The red
Every step of this workflow was executed by hand against #7614’s chart and passes there: the scale-out render contains StatefulSet + HPA + PrometheusRule, the no-CRD render fails with an error naming the CRD, and the operator-free render succeeds with zero PrometheusRule/PodMonitor. This check should go green on its own once #7614 merges. I deliberately did not make the step tolerant of both old and new chart behaviour — an assertion that passes either way would be worse than a stated dependency. |

Two targets matched nothing, and two whole families were unreachable by any target including `all`. Measured against phase-rs/phase on 2026-08-22 via `gh api --paginate /repos/phase-rs/phase/actions/caches` — 796 caches, 8.1 GiB against a 10 GiB per-repo ceiling: target pattern matched rust rust- 0 (real prefix is v0-rust-, 17, 3.48 GiB) pnpm node-cache-Linux-pnpm- 0 (real key has -x64, 2, 0.22 GiB) binaryen binaryen-version_ 1 (misses legacy binaryen-<ver>, 1) Uncovered by any target: 788 caches / 8.01 GiB, dominated by sccache/ (725, 3.52 GiB) and v0-rust- (17, 3.48 GiB), plus cardgen- (16). So "clear rust caches" silently deleted nothing while the quota stayed full. `actions-rust-lang/setup-rust-toolchain` prefixes its keys `v0-rust-`, and the pnpm store key embeds the runner arch (`node-cache-Linux-x64-pnpm-…`); the targets were off by exactly those prefixes. `gh cache list --key` is a prefix match (verified: `--key binaryen-` returns both key shapes), so each target is now the shortest prefix covering its family, `rust` covers both Rust families, `pnpm` becomes `node`, and `cardgen` is added. Correcting the prefixes alone would have introduced a new silent failure: `gh cache list --limit 100` caps one pass at 100 entries (measured — `--key sccache/ --limit 100` returns 100 while `--limit 1000` returns 755), so a working `rust` target would delete 100 of 725 and report success. The delete step now re-lists until a pass finds nothing, stops early if a pass makes no progress (an undeletable key cannot spin forever), and reports a per-prefix count. `timeout-minutes` goes 5 -> 30, since each delete is one API call. Verified against a stubbed `gh` over a 744-key fixture: the old step deleted 0 with the old `rust` pattern and 117/742 with corrected prefixes, while the new step deletes 742/742, leaves other families untouched, and terminates against an undeletable key. actionlint clean.

The chart had no CI at all: a broken template or a values change that stops rendering would only surface at `helm install` time, on somebody's cluster. `helm lint` plus four renders, because the opt-in paths produce entirely different workloads and a default-values render alone leaves most of the chart untested: defaults, scale-out with metrics and autoscaling, the same values with the PrometheusRule CRD absent (which must now FAIL, since hpa.yaml would otherwise install an autoscaler whose only producer of `phase:wanted_replicas` was silently skipped), and the operator-free path where the recording rule is supplied externally (which must still render). The renders then assert the chart's central storage invariant, since two processes on one games.db is destructive: the default path stays a single-replica Deployment, and scale-out gives every ordinal its own claim. Forbidden-resource assertions are written `if grep -q X; then exit 1; fi` rather than `! grep -q X`: a `!`-negated command is exempt from `set -e`, so the latter never failed the step and the "must not contain" half of every no-CRD assertion was vacuous. Verified against bash directly before rewriting. Actions are pinned by commit SHA rather than mutable tag, and the checkout is given `persist-credentials: false` — the job only reads the tree. Assisted-by: ClaudeCode:claude-opus-5
`PHASE_MAX_CONNECTIONS`, `PHASE_MAX_GAMES`, `PHASE_METRICS_PORT` and `PHASE_REPLICA_ORDINAL` are read by phase-server but were not listed with the other `PHASE_*` variables, so the reference an agent consults to answer "how do I configure this server" did not mention them. Documentation only: four lines in an env-var list, no change to any instruction or agent behaviour. Assisted-by: ClaudeCode:claude-opus-5
The chart tests `APIVersions.Has` per resource, and a real cluster's discovery populates both the group and the kind forms. Passing only the group renders no monitors at all — measured against the chart this workflow targets, the scale-out render produced zero PodMonitors — and the step's assertions covered only StatefulSet, HPA and PrometheusRule, so it would have gone green on a render that silently dropped them. Both kinds are now passed and both are asserted. `serviceMonitor` is off by default, so the render enables it to reach the second gate. Assisted-by: ClaudeCode:claude-opus-5
The chart refuses `scaleOut.scheme: http` while it renders its own TLS routes, because the advertised ordinal URL becomes the client's "CODE@host" share link and would name an address nothing serves. Nothing here exercised that. Three cases: http with the chart's ingress on must fail and the error must name the knob; https must still render one entry route plus one per ordinal; and http with ingress.enabled=false must render no route at all and advertise the http prefix, because there the operator owns the edge. The https case is the one that keeps the first honest — without it the step would pass on a chart that rejected every scheme. Assisted-by: ClaudeCode:claude-opus-5
The HPA reads `phase:wanted_replicas`, the PrometheusRule produces it, and the rule reads gauges only a PodMonitor or ServiceMonitor scrapes. A partial operator install can register the rule's CRD and neither monitor's, and nothing here noticed: the chart rendered the rule and the HPA with no scrape target. The must-fail case covers exactly those capabilities. The control adds only the PodMonitor kind and asserts all three resources render, so the step tracks the missing CRD rather than passing on a chart that refused autoscaling outright. Assisted-by: ClaudeCode:claude-opus-5
The no-operator-CRD step matched the failure message on the phrase "prometheus-operator CRDs". That message was reworded when the guard moved from testing the API group to testing the PrometheusRule resource, and the assertion silently stopped matching: the render still failed for the right reason, but the step would have failed on the grep. It went unnoticed because an earlier step was red, so this one never ran. Matching on `monitoring.coreos.com/v1/PrometheusRule` ties the assertion to the capability under test rather than to wording. Assisted-by: ClaudeCode:claude-opus-5
The storage invariant exists to keep the default path a single-replica Deployment, but it only checked `replicas: 1`. A default that became a single-replica StatefulSet satisfies that string exactly, so the check would have passed on the shape it is there to prevent — confirmed by rendering one: `replicas: 1` matches, `kind: Deployment` does not.

Approved at current head 165eebd04720bd4f511004325fb100842d0eb6e2 under explicit maintainer authorization for the reviewed workflow and skill-path changes. Current CI, including Helm lint/template validation, is green; the prior request-for-changes is stale and the resolved workload-kind review finding remains covered.

Split out of #7614 at maintainer request: that PR touches
.claude/skills/**and.github/workflows/**, which are hard-stop paths on the contributor merge path. This PR carries only those three files so they can be reviewed in isolation; #7614 keeps the server and Helm-chart work and no longer touches either surface.helm-chart.ymlrenders the chart as #7614 leaves it. Two of its steps assert behaviour introduced there — that autoscaling without thePrometheusRuleCRD fails to render, and that the operator-free path still renders. Against today'smainthose steps fail, because the chart has no scale-out or autoscaling yet. This ordering is real and I have not tried to paper over it: making the step tolerant of both old and new behaviour would turn it into an assertion that passes either way, which is worse than a stated dependency.Until this lands, #7614 has no chart CI at all.
What's here
clear-caches.yml— the targets matched almost nothing. Measured againstphase-rs/phaseon 2026-08-22 viagh api --paginate /repos/phase-rs/phase/actions/caches: 796 caches, 8.1 GiB against a 10 GiB ceiling.rustrust-v0-rust-(17, 3.48 GiB)pnpmnode-cache-Linux-pnpm--x64(2, 0.22 GiB)binaryenbinaryen-version_binaryen-<ver>788 caches / 8.01 GiB were unreachable by any target including

Fixing the prefixes alone would have introduced a new silent failure:gh cache list --limit 100caps a pass at 100 entries (measured), so a workingrusttarget would delete 100 of 725 and report success. The delete step now re-lists until a pass finds nothing and stops early if a pass makes no progress.gh cache listalso lost its|| true, which made a failed list read as "no matching caches" and report success having deleted nothing.helm-chart.yml— the chart had no CI.helm lintplus four renders: defaults; scale-out with metrics and autoscaling; the same values with thePrometheusRuleCRD absent (must fail); and the operator-free path with an externally supplied recording rule (must render). The renders then assert the storage invariant — default stays a single-replica Deployment, scale-out gives every ordinal its own claim — because two processes on onegames.dbis destructive.Forbidden-resource assertions are
if grep -q X; then exit 1; fi, not! grep -q X. A!-negated command is exempt fromset -e, so the negated form never failed the step and every "must not contain" assertion was vacuous. Verified against bash directly:Actions are pinned by commit SHA rather than mutable tag, and the checkout gets
persist-credentials: false(the job only reads the tree). Worth a maintainer opinion: this makes it the only SHA-pinned workflow in the repo —.github/workflows/*.ymlcurrently has 148 tag-pinneduses:lines and 0 SHA-pinned, andpersist-credentialsappears nowhere. Happy to switch to tag pins for consistency, or treat this as step one of a repo-wide change. Your call.SKILL.md— four lines of env-var documentation.PHASE_MAX_CONNECTIONS,PHASE_MAX_GAMES,PHASE_METRICS_PORT,PHASE_REPLICA_ORDINALare read by phase-server but were missing from thePHASE_*list. Documentation only — no instruction or agent-behaviour change. If this is acceptable back in #7614 I'll move it there and drop it here.Verification
actionlintclean. Every step's shell logic executed against #7614's chart: scale-out render contains StatefulSet + HPA + PrometheusRule; the no-CRD render fails with an error naming the CRD; the external-rule render succeeds with zero PrometheusRule/PodMonitor; and the rewritten assertion form was confirmed to fire on a resource that is present.Update (41f0b80): kept in step with #7614's per-kind monitor gating
#7614 now gates
podmonitor.yamlper resource (monitoring.coreos.com/v1/PodMonitorand
.../ServiceMonitortested separately) rather than by API group, because apartial operator install otherwise renders a kind that is not installed and
fails at apply.
That made this workflow's
--api-versionsflags stale: passing only the groupform, the scale-out render produces zero PodMonitors — measured against
#7614's chart. The step asserted only StatefulSet, HPA and PrometheusRule, so it
would have gone green on a render that silently dropped both monitors.
Both kind forms are now passed and both are asserted, so the flags are
load-bearing rather than decorative.
metrics.serviceMonitor.enabledisfalseby default, so the render sets it to reach the second gate. Verified against
#7614's chart: with the old flags
kind: PodMonitorcount is 0 (the newassertion fails); with the new flags PodMonitor, ServiceMonitor and
PrometheusRule are each present once.
This is maintenance to keep B consistent with A. The ordering coupling stated
above is unchanged: these steps still require #7614's chart to be merged first.
Update (498b468): cover both advertised scale-out schemes
#7614 now refuses

CODE@hostsharelink, so
httpwould name an address nothing serves. Nothing here exercisedthat guard.
Three cases:
scheme=http, chart ingress onscaleOut.schemescheme=https, chart ingress onreplicaMax: 3)scheme=http,ingress.enabled=falsehttp://phase-The https case is what keeps the first honest: without it the step would pass on
a chart that rejected every scheme, not just the contradictory one.
Verified by running the step verbatim against #7614's chart — passes there, and
fails with

Update (6ca194d): reject autoscaling with no monitor CRD
#7614 gained a guard for a hole its own per-kind monitor gating opened: a
cluster carrying
monitoring.coreos.com/v1/PrometheusRulebut neither monitorCRD rendered the recording rule and the External-metric HPA with nothing
scraping the gauges they read. Nothing here caught it.
The must-fail case renders with exactly those capabilities. The control adds
only the PodMonitor kind and asserts PodMonitor, PrometheusRule and HPA all
render — without it the step would pass on a chart that refused autoscaling
outright rather than one that tracks the missing CRD.
