AI_CONTEXT_FEATURES = ["guards", "sinks", "validators", "signals", "callee", "all"]

--ai-context accepts an optional comma-separated feature list. Crystal's OptionParser cannot express "optional positional value", so we rewrite the few well-defined ambiguous forms upfront:

--ai-context → --ai-context= (bare, all features) --ai-context=guards,sinks → unchanged (explicit value) --ai-context guards,sinks → --ai-context=guards,sinks (heuristic) --ai-context ./app → --ai-context= (next token is a path)

The heuristic for "is the next token a feature list?" is intentionally tight: lowercase comma-separated words drawn from a fixed vocabulary. This keeps noir scan --ai-context ./app working as a positional path.

AI_CONTEXT_VALID_FEATURES = {"guards", "sinks", "validators", "signals", "callee", "all"}

--ai-context[=LIST] always enables AI context output. An empty LIST means "every category"; a non-empty LIST narrows the output to the named categories.

ALLOWED_HTTP_METHODS = ["GET", "POST", "PUT", "DELETE", "PATCH", "OPTIONS", "HEAD", "TRACE", "CONNECT", "QUERY"]

ANDROID_EMBEDDED_SERVER_MARKER = /io\.ktor\.server\.|embeddedServer|\brouting\s*\{|\bfun\s+Route\.|org\.http4k\.routing|@RestController|@RequestMapping|@(?:Get|Post|Put|Delete|Patch)Mapping|\bRouterFunction\b/

Strong server-routing constructs. A .kt / .java file that sits inside an Android app's source set is normally scoped to mobile detectors only (an incidental import ...SpringApplication must not flag the project as a server). But an Android app can legitimately embed an on-device HTTP server — e.g. plain-app runs a local Ktor web server whose routes live under app/src/main/java/.... When a file carries one of these markers it is a real server, so the Ktor / http4k / Spring detectors are allowed to run on it. Kept as a single precompiled constant — recompiling it per file would recreate the PCRE2 program on every read.

DETECTOR_PATH_SEGMENT_PROBES = ["proj/grails-app/conf/application", "proj/supabase/migrations/001.sql", "proj/migrations/001.sql", "proj/supabase/config.toml", "proj/server/api/hello.js", "proj/server/routes/hello.js", "proj/pages/api/hello.js", "proj/app/api/hello/route.ts", "proj/routes/+server.ts", "proj/routes/index.dart", "proj/directus/snapshots/snap.json", "proj/wp-content/plugins/x.php", "proj/metadata/databases/tables.yaml", "proj/Magento/module.xml"]

Paths that embed directory segments real detectors gate on (/grails-app/, /migrations/, /server/api/, …). Used only to classify path-sensitive detectors — not as production file samples.

DETECTOR_SPECIAL_BASENAMES = Set {"package.json", "tsconfig.json", "composer.json", "composer.lock", "vercel.json", "now.json", "netlify.toml", "wrangler.toml", "Gemfile", "Gemfile.lock", "Package.swift", "Cargo.toml", "go.mod", "mix.exs", "pubspec.yaml", "pubspec.lock", "shard.yml", "shard.lock", "build.sbt", "pom.xml", "AndroidManifest.xml", "config.toml", "rebar.config", "erlang.mk", "project.clj", "deps.edn", "stack.yaml", "package.yaml", "gleam.toml", "manifest.toml", "paket.dependencies", "Caddyfile", "Dockerfile", "Makefile", "Rakefile", "serverless.yml", "serverless.yaml", "app.yaml", "openapi.yaml", "openapi.json", "swagger.json", "swagger.yaml"}

Filenames that detectors match by exact basename (often with path constraints like "must sit at the project root"). These must not share an extension-only cache bucket — e.g. vercel.json is not "any .json".

INCLUDE_TARGETS = {"path" => "include_path", "techs" => "include_techs", "callee" => "include_callee"}

LEGACY_INCLUDE_TARGETS = {"--include-path" => "include_path", "--include-techs" => "include_techs", "--include-callee" => "include_callee"}

LEGACY_PVALUE_TARGETS = {"--set-pvalue" => "set_pvalue", "--set-pvalue-header" => "set_pvalue_header", "--set-pvalue-cookie" => "set_pvalue_cookie", "--set-pvalue-query" => "set_pvalue_query", "--set-pvalue-form" => "set_pvalue_form", "--set-pvalue-json" => "set_pvalue_json", "--set-pvalue-path" => "set_pvalue_path"}

Silently translate v0 flag spellings to their v1 storage. Keeping the work here (instead of parser.on "--include-path") means the legacy names no longer clutter noir scan -h, while every v0 script keeps working untouched in v1.x.

MOBILE_DETECTOR_NAMES = Set {"android", "ios", "well_known_applinks"}

PVALUE_TYPE_KEYS = {"any" => "set_pvalue", "all" => "set_pvalue", "header" => "set_pvalue_header", "cookie" => "set_pvalue_cookie", "query" => "set_pvalue_query", "form" => "set_pvalue_form", "json" => "set_pvalue_json", "path" => "set_pvalue_path"}

Split TYPE=VAL (or bare VAL → all-types) and route it into the right slot in noir_options. --pvalue may be repeated to set multiple values across different types.
