+# cross-file-consistency Specification
+
+## Purpose
+Defines facts that kollect states in more than one file and the gates that fail when those
+statements disagree, so drift is found by CI and not by a user or an outage.
+
+## Requirements
+
+### Requirement: CFC-1 The shipped binary is built with the tested toolchain
+
+The Go version in the `FROM golang:<version>` line of every `Dockerfile*` that builds Go, and in
+the `golang:<version>` image of `.devcontainer/devcontainer.json`, SHALL equal the `go` directive
+of `go.mod`. `go.mod` SHALL carry no separate `toolchain` line, and every
+Go setup in CI SHALL use `go-version-file: go.mod`. Renovate SHALL move the `go` directive and the
+golang image tag in one group.
+
+#### Scenario: Equal
+
+- **WHEN** `go.mod` and every Dockerfile name the same Go version
+- **THEN** the check passes
+
+#### Scenario: Image differs from go.mod
+
+- **WHEN** a Dockerfile or the devcontainer image names a newer or older Go than `go.mod`
+- **THEN** the check SHALL fail and name the file and both versions, because tests and govulncheck run the go.mod toolchain and never see the one that ships
+
+#### Scenario: Lone image PR
+
+- **WHEN** Renovate opens a PR bumping only the golang image (group rule missing, mis-ordered after a more general rule, or the manager does not bump the `go` directive)
+- **THEN** the check turns red on that PR, and the guard also checks the group rule's presence and order
+
+#### Scenario: Toolchain line or literal
+
+- **WHEN** `go.mod` gains a `toolchain` line or a workflow adds a Go version literal
+- **THEN** the check SHALL fail
+
+#### Scenario: No Go image found
+
+- **WHEN** the scan finds no `golang:` line
+- **THEN** the check SHALL fail; an empty scan never passes
+
+### Requirement: CFC-2 Pinned tools build with the repository's Go
+
+Every tool pinned through `go run <pkg>@<version>` or `go install` SHALL build under
+exactly the Go of `go.mod` (`GOTOOLCHAIN=go<version>`, never `auto` and never whatever Go the
+host has); the check reads each tool's required Go from
+`go mod download -json` and fails when it exceeds `go.mod`'s. Each pinned analysis tool SHALL also
+run once against the module under that Go and exit cleanly.
+
+#### Scenario: Tool needs a newer Go
+
+- **WHEN** a pinned tool's `go` directive is newer than `go.mod`'s
+- **THEN** the check SHALL fail and name the tool, version and both Go versions
+
+#### Scenario: Analysis tool too old for go.mod's Go
+
+- **WHEN** a pinned analysis tool (golangci-lint, govulncheck, go-arch-lint) is older than `go.mod`'s Go, so it cannot load or analyse the module (its `golang.org/x/tools` predates that Go)
+- **THEN** the check SHALL fail and name the tool and version, because a smoke run of each analysis tool under `go.mod`'s Go exits non-zero or panics; one clean run is the pass condition
+
+#### Scenario: Tool lookup fails
+
+- **WHEN** `go mod download` cannot resolve a pin (network or typo)
+- **THEN** the check SHALL fail; an unresolved pin is never a pass
+
+#### Scenario: Transition after a Go bump
+
+- **WHEN** `go.mod`'s Go is raised
+- **THEN** every tool pin is rechecked in the same PR
+
+### Requirement: CFC-3 The chart grants at least what the kustomize role grants
+
+Every (apiGroup, resource, verb) triple in `config/rbac/role.yaml` SHALL be granted by the manager
+roles rendered from `charts/kollect` with default values, unless listed with a reason in
+`hack/test/testdata/consistency-rbac-exceptions.txt`.
+
+#### Scenario: Chart matches
+
+- **WHEN** the rendered roles cover every triple of `role.yaml`
+- **THEN** the check passes
+
+#### Scenario: A kubebuilder marker adds a permission the chart lacks
+
+- **WHEN** a controller gains `+kubebuilder:rbac` for a new resource and `make manifests` updates `role.yaml`, but the chart templates are not changed
+- **THEN** the check SHALL fail and name the missing triple
+
+#### Scenario: Exception without a reason
+
+- **WHEN** an exception line has no reason text
+- **THEN** the check SHALL fail
+
+#### Scenario: Tenant mode
+
+- **WHEN** the chart is rendered with `tenantMode=true`
+- **THEN** namespaced triples are covered by the rendered namespaced `Role`; cluster-scoped triples (namespaces, tokenreviews, subjectaccessreviews, selfsubjectaccessreviews, `kollectcluster*`) appear as listed exceptions with the reason that tenant mode drops cluster scope; namespaced
+  workload-collection reads (today `apps/deployments` and `cert-manager.io/certificates`, get/list/watch)
+  appear as listed exceptions with the reason that tenant mode leaves workload RBAC to the team
+  (`docs/examples/team-operator.md` §3); any other namespaced triple missing from the `Role` fails
+
+### Requirement: CFC-4 Metric names agree between code, docs and chart
+
+Every `kollect_*` metric name in `docs/operator-manual/metrics.md` and in
+`charts/kollect/templates/prometheusrule.yaml` (histogram suffixes `_bucket`, `_sum`, `_count`
+stripped) SHALL be registered in the non-test source of `internal/metrics` other than
+`metrics_catalog.go`, every registered metric SHALL appear in `metrics.md`, and
+`registeredMetricNames` SHALL equal that source set.
+
+#### Scenario: Alert on a renamed metric
+
+- **WHEN** a metric is renamed in code and `prometheusrule.yaml` still queries the old name
+- **THEN** the check SHALL fail and name the rule file and the unknown metric
+
+#### Scenario: New metric without docs
+
+- **WHEN** a metric is registered and absent from `metrics.md`
+- **THEN** the check SHALL fail and name the metric
+
+#### Scenario: Catalog is not registration
+
+- **WHEN** a name appears only in `metrics_catalog.go`
+- **THEN** it does not count as registered
+
+#### Scenario: Mirror list not updated
+
+- **WHEN** a metric is added to `metrics.go` but not to `registeredMetricNames`
+- **THEN** the check SHALL fail
+
+#### Scenario: Histogram suffix
+
+- **WHEN** a rule queries `kollect_export_duration_seconds_bucket`
+- **THEN** it is accepted as the registered histogram
+
+#### Scenario: Empty scan
+
+- **WHEN** the source scan returns no names
+- **THEN** the check SHALL fail
+
+### Requirement: CFC-5 Falling behind the latest Go patch is a red signal
+
+A scheduled workflow SHALL fail when the `go` directive of `go.mod` is behind the latest released
+patch of its minor, and SHALL fail when the latest patch cannot be determined.
+
+#### Scenario: Behind
+
+- **WHEN** `go.mod` names patch N and the latest release of that minor is N+1
+- **THEN** the scheduled run is red and says so (the CI-failure reporter, once present, files an issue)
+
+#### Scenario: Current
+
+- **WHEN** `go.mod` equals the latest patch
+- **THEN** the run is green
+
+#### Scenario: Lookup fails
+
+- **WHEN** the release listing is unreachable or unparsable
+- **THEN** the run SHALL fail, not pass
+
+#### Scenario: Newer minor exists
+
+- **WHEN** a newer minor than `go.mod`'s exists
+- **THEN** the sensor does not fail on that alone
+
+### Requirement: CFC-6 Each consistency gate is proven able to fail
+
+Each check SHALL contain a self-test that corrupts a copy of the tree to break its invariant and
+asserts a non-zero exit, plus a no-op copy that must pass, and SHALL run on `pull_request` in a
+required job, plain and `--self-test` as separate steps.
+
+#### Scenario: Mutant survives
+
+- **WHEN** corrupting the copy does not make the check exit non-zero
+- **THEN** the self-test SHALL fail
