Suppression Markers 🚫

The unified # noqa / # nocheck syntax that suppresses individual checks across the infinito-nexus test suite.

You MUST use these markers only when the check genuinely does not apply. You MUST NOT use them to silence legitimate issues.

Grammar 📐

A suppression marker is a comment carrying one or more rule keys:

<comment-prefix> (noqa|nocheck): <rule>(, <rule>)*

noqa and nocheck are case-insensitive synonyms in the parser. Every project rule MUST use nocheck: because # noqa: <code> is also parsed by ruff as a flake8 directive and warns on non-flake8 keys. Reserve noqa: for real flake8 / ruff codes (E402, F401, …). test_noqa_only_ruff_codes.py hard-rejects # noqa: <code> whose codes do not match [A-Z]+\d+.

<rule> is a kebab-case identifier from the catalog below. Multiple rules MAY be combined comma-separated.

Prefix	Use in
#	Python, YAML, shell, conf, INI, …
//	JS, JSONC, …
{# … #}	Jinja2 templates
<!-- … -->	HTML, Markdown

Implementation: suppress.py.

Position semantics 📍

The placement rule is per check. The catalog "Position" column uses these labels.

Label	Meaning
same line	Marker MUST be on the construct's line.
same line / span	Marker MUST be on the construct's line or any physical line spanned by a multi-line call.
line above	Marker MUST be on the immediately preceding non-empty line. Blank lines break the association.
same or above	Either of the above is accepted.
comment block above	Marker MAY sit on any line of a contiguous comment block above the construct. No blank line between marker and construct.
head (first 30 lines)	Marker MAY appear anywhere in the first 30 lines of the file. For file-level opt-outs that stay visible at the top.
anywhere	Marker MAY appear on any line of the file. For whole-file opt-outs.

Catalog 📚

Rule	Position	Affected test	Effect
url	same or above	test_urls_reachable.py	Skips probing the literal HTTP(S) URL. Use for CDN roots and API base URLs that 4xx without a path.
docker-version	same or above	test_image_versions.py, test_semver_pinning.py	Skips both the live version-update warning and the non-semver-pin lint for that image's version: key.
repository-version	same or above	test_repository_versions.py, test_semver_pinning.py	Skips both the live ref-update warning and the non-semver-pin lint for that entity's ref: key.
dockerfile-arg-default	same or above	test_arg_without_default.py	Allows the marked ARG to carry a default. The caller normally supplies every build argument so a missing one fails the build instead of selecting a base image nobody chose.
direct-yaml	same line / span	test_no_direct_calls.py	Allows the marked yaml.safe_load / safe_dump call to bypass utils.cache.yaml. MUST use nocheck:, not noqa:.
curl-timeout	same or above	test_curl_via_filter.py	Allows a bare curl invocation without the curl filter or inline --max-time.
redundant-bool-ternary	same line	test_no_redundant_bool_patterns.py	Allows the redundant | bool | ternary('true','false') pattern when a consumer requires the lowercase tokens.
redundant-bool-comparison	same line	test_no_redundant_bool_patterns.py	Allows ... | bool == True/False/true/false when a real tri-state guard is intended (distinguishing None from False).
shared	comment block above	test_service_shared_consistency.py	Marks a service whose enabled: true does not require shared: true.
email	line above	test_email.py	Suppresses the missing-email-integration warning. Pair with enabled: false and shared: false.
logout	line above	test_logout_dashboard.py	Opts a web-app-* role out of the universal-logout integration. Marker MUST be directly above logout:. Pair with enabled: false and shared: false.
dashboard	line above	test_logout_dashboard.py	Opts a web-app-* role out of the dashboard tile integration. Same shape as logout.
sso	line above	test_sso.py	Opts the role's unified services.sso block out. Declares "no login flow"; paired with enabled: false + shared: false.
file-size	head (first 30 lines)	test_python_file_size.py	Opts the entire .py file out of the 500-line cap.
comments-valid	head (first 30 lines)	test_comments_valid.py	Opts the entire file out of the useful-comment check. Reserved for vendored / upstream config templates (e.g. Discourse app.yml) whose inline documentation is all intentional.
info-media	head of meta/main.yml (first 30 lines)	test_info_homepage_video.py	Opts an invokable role out of the required meta/info.yml homepage + video entries. Marker lives in meta/main.yml (a comment-only info.yml would fail the info schema lint). Reserved for fully self-written roles (backups, host plumbing) that have no upstream product page or demo video.
project-walk	same line / span	test_no_raw_project_walk.py	Allows a raw Path.rglob, os.walk, or glob.glob call outside the utils.cache.files.iter_project_files contract.
cache-read	same line / span	test_no_uncached_file_reads.py	Allows a raw Path.read_text / Path.read_bytes call in tests/lint/ outside the LRU-cached utils.cache.files.read_text contract.
lookup-cache-import	same or above	test_no_cache_imports_in_lookups.py	Allows a lookup plugin (plugins/lookup/ or roles/*/lookup_plugins/) to import a config-merge function from utils.cache.applications / .domains / .users instead of reaching the SPOT via lookup_loader.get('applications'/'config'/'domains'/'users'). Reserved for the SPOT providers (applications / config / applications_current_play / users / domains) and the raw-volume accessors (volume / nginx).
run-once	anywhere	test_run_once_tags.py, test_schema.py	Marks a role's tasks/main.yml as intentionally re-runnable. Skips both the run-once tag check and the suffix check.
run-once-suffix	same line	test_schema.py	Allows a single when: item to reference a run_once_<other> flag whose suffix differs from the current role.
raw-docker	same or above; head (first 30 lines)	test_no_raw_docker.py	Marks a single line or a whole file under roles/ as legitimately calling docker / docker compose / docker-compose directly.
hardcoded-dns-resolver	same or above	test_no_hardcoded_dns_resolvers.py	Marks a line that needs a literal IP from NETWORK_PUBLIC_DNS_RESOLVERS where the substitution point cannot consume the variable (CoreDNS non-Jinja templates, host-bootstrap shell, doc examples).
dynamic-flag	same line OR comment block above key	test_dynamic_flags.py	Marks a roles/*/meta/services.yml flag whose value stays literal. Per-flag (same line) for databases. Block-level (comment block above) when both flags stay literal.
native-metrics	comment block above	test_native_metrics_contract.py	Marks a role whose services.prometheus.native_metrics.enabled and templates/prometheus.yml.j2 presence are intentionally inconsistent. Reserved for prepared-but-default-off scrape fragments (operator opt-in).
prometheus-scrape	same or above	test_roles_with_service.py	Documents a services.prometheus.scrape: false opt-out in roles/<role>/meta/services.yml. The role keeps services.prometheus.{enabled,shared}: true (so the role-wiring contract stays satisfied) but roles_with_service('prometheus') drops it from PROMETHEUS_TARGET_ROLES_JSON. Reserved for 301-redirect-only vhosts that never serve a request through lua-resty-prometheus, so they emit no app="<role>" label and have no scrape target. The marker accompanies the scrape: data flag the lookup honors.
matomo-track	same or above	test_roles_with_service.py	Documents a services.matomo.track: false opt-out in roles/<role>/meta/services.yml. The role keeps services.matomo.{enabled,shared}: true (so the role-wiring contract stays satisfied) but roles_with_service('matomo') drops it from MATOMO_TARGET_ROLES_JSON and the matomo tracker e2e contract. Reserved for static-file (autoindex) and 301-redirect vhosts that carry no user-facing HTML page worth a _paq tracker. The marker accompanies the track: data flag the lookup honors.
variants-static-override	same line	test_variants_no_static_override.py	Allows a roles/*/meta/variants.yml leaf override of an attribute whose base value in meta/services.yml is a static literal. Place on the override line in variants.yml. Use only when the consumer chain is provably immune to the variant-merge propagation gap; the default is to make the base value dynamic via "{{ '<role>' in group_names }}".
variants-shared-false-once	same or above	test_variants_shared_false_once.py	Exempts one roles/*/meta/variants.yml services.<key>.shared: false pin from the one-local-provider-variant limit for a service whose base meta/services.yml uses literal enabled: true and dynamic shared. Place on the extra shared: false line or service key line. Place above the service key in meta/services.yml to exempt the service.
variants-services-match	same or above	test_services_match.py	Allows a roles/*/meta/variants.yml services.<key> entry to reference a service key that is NOT declared as a top-level entry in meta/services.yml. Reserved for resolver-only matrix hooks (typically on invokable infrastructure roles) whose variant entries pin the round's companion topology via service-key flags the resolver maps to provider roles, with no real consumer contract in the base meta.
variants-auth-isolation	same or above	test_auth_isolation.py	Exempts an auth-isolated variant entry in roles/*/meta/variants.yml (one that enables exactly one of LDAP / OIDC / OAuth2) from the rule that every non-auth service-key in the role's variant union must be pinned to literal false. Place on the leading - services: line of the variant or on the line above. Use only when the broader closure is intentional.
lookup-config-path	same or above	config/	Skips a single lookup('config', …) call from path-validation passes. Use when the call resolves against runtime-only state, typically self-referential roles.
unused-var	same or above	test_role_and_group_vars_used.py	Exempts a top-level key in roles/<role>/{vars,defaults}/main.yml or group_vars/**/*.yml from the "must be referenced" check. Use when the consumer is non-YAML/Jinja (Python plugins, external tools).
project-root-import	same or above	test_project_root_import.py	Permits a local PROJECT_ROOT / parents[N] / os.pardir chain. Reserved for __main__.py sys.path bootstrap and standalone scripts under roles/<role>/files/. The marker MUST carry an inline explanation.
domain-spot	same or above	test_domain_primary_spot.py	Marks a line using a <word>.{{ DOMAIN_PRIMARY }} host literal outside the meta SPOT. Reserved for legacy domain cleanups that the canonical SPOT cannot represent.
literal-protocol-lookup	same or above	test_literal_protocol_with_lookup.py	Allows a hardcoded http:// / https:// literal next to a lookup(...) call. Reserved for genuinely fixed protocols (Docker-network upstreams, loopback URLs in CI fixtures).
self-path-reference	same line	test_no_self_path_reference.py	Allows a file to contain its own relative path from the repo root as a string literal. Reserved for load-bearing self-references. Repo-root files are exempt without a marker.
role-file-spot	same or above	test_file_spot.py	Allows a .py file to carry a literal role-file path instead of the matching ROLE_FILE_* constant from utils.roles.mapping. Reserved for tests asserting the constant's value, migration scripts, or doc strings.
playwright-service-flag	comment block above	test_env_services_match.py	Exempts a top-level service in roles/<role>/meta/services.yml from the "must be registered as <NAME>_SERVICE_ENABLED= in templates/playwright.env.j2" check.
playwright-service-gate	same or above	test_spec_env_gates.py	Exempts a <NAME>_SERVICE_ENABLED= line in roles/<role>/templates/playwright.env.j2 from the "must be gated in files/playwright/playwright.spec.js" check.
pkgmgr-deprecated	same or above	test_pkgmgr_deprecated.py	Suppresses the warn-only deprecation notice for include_role / import_role of pkgmgr / pkgmgr-install. The check emits a DeprecationWarning locally and a GitHub Actions ::warning annotation in CI. Prefer pip install <name> or pip install git+<repo>.
deprecated-http-header	same or above	test_no_deprecated_http_security_headers.py	Exempts a deprecated add_header / Header set/add line for X-Frame-Options / X-XSS-Protection / X-Download-Options / X-Permitted-Cross-Domain-Policies. Prefer Content-Security-Policy via the role's meta/server.yml (csp.flags / csp.whitelist).
container-name	same or above	test_mode_incompatible_keys.py	Allows a raw container_name: key in a roles/*/templates/**/*.j2 template. Default path: route through the generic compose_only lookup ({{ lookup('compose_only', 'container_name', NAME) }}) so swarm-mode replicas do not collide on the static name.
pull-policy-key	same or above	test_mode_incompatible_keys.py	Allows a raw pull_policy: key in a roles/*/templates/**/*.j2 template. Default path: route through the generic compose_only lookup ({{ lookup('compose_only', 'pull_policy', 'never') }}) so swarm does not reject the compose-only extension with "Additional property pull_policy is not allowed".
restart-key	same or above	test_mode_incompatible_keys.py	Allows a raw restart: key in a roles/*/templates/**/*.j2 template. Default path: route through the compose_restart lookup so swarm-mode does not silently drop the operator's docker_restart_policy.
compose-structure	same or above; head (first 30 lines)	test_compose_template_structure.py	Exempts a roles/*/templates/*compose.yml.j2 line, or the whole file (head marker), from the canonical compose skeleton: base-include header, {{ service_name }}: service keys each preceded by their {% set service_name %}, all per-service {% set %} knobs on two-space-indented dash-free lines above the key, {% include %} at four spaces inside the service body, and column-0 compose_volumes / compose_networks at the tail. The layout renders correctly because the stack_host_template action plugin sets lstrip_blocks=True for compose.yml.j2. Reserved for legitimate deviations that genuinely cannot follow the skeleton.
seaweedfs-required	head (first 30 lines)	test_database_requires_seaweedfs.py	Exempts a database-backed web-app-* role from the requirement to declare a seaweedfs object-store service. Place in the head of roles/<role>/meta/services.yml. Use only when the application genuinely needs no object storage.
tor-contract	anywhere in file	test_tor_contract.py	Exempts a domain-serving role (web-/svc-db- prefix or explicit domains.canonical) from the "must declare a tor: block in meta/services.yml" contract. Reserved for roles with no onion surface, e.g. pure redirect helpers.
templated-conditional	same or above	test_no_templated_conditionals.py	Exempts a when / failed_when / changed_when / until value that legitimately carries {{ }} / {% %}. Reserved for genuine edge cases; the default path is a bare expression. Per-item render/apply data guards belong on a condition: data field (honored by the sys-svc-compose render helper and LISTMONK_SETTINGS), not when:.
container-address-quote	same or above	test_address_never_quoted.py	Allows *_CONTAINER_ADDRESS | quote in a role task file. Reserved for sites that never see the swarm $(...) fragment (DEPLOYMENT_MODE == 'compose'-gated tasks, compose_mode_force roles) or consumers that re-evaluate the argument themselves.
container-exec-resolver	same or above; argv: target item	test_exec_uses_resolver.py	Allows a container exec / container inspect target that does not route through the container_address lookup. Reserved for a container ID already resolved at delegate_to runtime (*_LOCAL_CID), where the lookup would return a manager-only subshell, and for deliberate bare-name partner probes gated on compose co-location.
container-inspect-type	same or above; argv: inspect item	test_inspect_pins_type.py	Allows an untyped container inspect under roles/. Default path: pin --type container, because a role's overlay network carries the same entity name as its main container, so an untyped inspect can resolve the network and report map has no entry for key "State". Use the typed subcommand (container volume inspect etc.) when the target genuinely is not a container.
container-healthcheck-unused	same or above the service key or its healthcheck: line	test_container_healthcheck_declared_is_used.py	Allows a services.<key>.healthcheck that no lookup('container_healthcheck', …) call renders. Default path: add the lookup to the service block, because an unrendered declaration reads like the service is watched while the compose file carries no probe. Reserved for a call the static resolver cannot attribute — mastodon renders every service through a macro whose service_name is a macro parameter.
image-healthcheck	same or above the service key	test_image_healthcheck_declared.py	Allows a roles/*/meta/services.yml entry whose image ships no HEALTHCHECK to declare none either. Default path: add healthcheck: to the entry, because a container without a probe counts as healthy the moment its process starts — which is how a service that came back empty passes a restore drill. Reserved for containers nothing can probe: a one-shot process that exits, or an image with neither a port nor a shell.
csp-unsafe	same line	test_csp_unsafe_requires_justification.py	Documents an unsafe-*: true flag in roles/*/meta/csp.yml. MUST be paired with a Reason: on the same line naming what breaks without the relaxation. unsafe-inline re-admits the inline execution an XSS needs and unsafe-eval re-admits string-to-code, so the flag has to be verified against the running app, not copied from another role.
min-storage-headroom	same line OR comment block above key	test_min_storage_headroom.py	Allows a roles/*/meta/services.yml min_storage to exceed the measured compressed size of its own image:/version: by more than 1 GB. MUST be paired with a Reason: on the same comment line naming what occupies the space. Reserved for services whose data volume genuinely dominates the footprint; the default path is to lower the value, because an over-declared budget makes a host look too small and prunes a cache the deploy did not need to lose.

Tool-Native noqa Codes 🧹

Some Python files use Ruff-compatible uppercase # noqa codes. Ruff and related Python linters handle these, not suppress.py. They MAY appear when the local exception is intentional and clear from context.

Code	Tool meaning	Typical allowed use
BLE001	Blind exception caught	Narrow command-wrapper boundaries that convert any underlying failure into a domain-specific error.
E402	Module import not at top	Tests that MUST adjust sys.path or load fixtures before importing the module under test.
E731	Lambda assigned to variable	Small test-local callbacks or path formatters where a named function would add noise.
F401	Imported but unused	Re-export modules or import-probe tests where import success is the assertion.
SLF001	Private member access	Test-only introspection of parser or object internals when the public surface does not expose the needed state.

Adding a new rule 🆕

1. Pick a kebab-case <rule> identifier.
2. Decide which position semantic from the list above fits the check.
3. Use is_suppressed_at / is_suppressed_in_head / is_suppressed_anywhere from suppress.py in your test. Do NOT roll a new regex.
4. Add the rule to the catalog table on this page.
