Domain docs

Single-context repo. Read CONTEXT.md for domain language and testing/architecture vocabulary, and docs/adr/ for accepted architecture decisions. See docs/agents/domain.md.

First 60 Seconds

• Classify task type:
  • Info-only (triage/review/questions/docs guidance): no code edits and no test runs unless explicitly requested.
  • Code change: make minimal scoped edits and run only required checks from Testing Matrix.
• State assumptions explicitly. If uncertain, ask.
• If the task touches tooling/builds/linting, read package.json and tsconfig*.json before source files.
• Prefer repo scripts over reconstructing command bundles by hand:
  • pnpm check:quick: lint + typecheck
  • pnpm check:tooling: lint + typecheck + build
  • pnpm check:unit: unit + smoke
  • pnpm check: full non-integration validation
• Read at most 3 files first:
  • owning handler/module
  • one shared helper used by that handler
  • one downstream platform file if needed
• Define verifiable success criteria before editing.
• Decide docs/skills impact up front.

Scope

• Solve issues with the smallest context read.
• Keep changes scoped to one command family or module group.
• Preserve daemon session semantics and platform behavior.
• Expand only when contracts cross module boundaries.
• Do not read both iOS and Android paths unless explicitly cross-platform.
• If requested fix expands beyond one command family/module group, stop and confirm before broadening scope.

Code Changes

• Minimum code that solves the problem. No speculative features.
• No abstractions for single-use code.
• Surgical edits only.
• Match existing style.
• Remove imports/variables YOUR changes made unused; do not clean unrelated dead code.
• Keep tests minimal: if TypeScript can enforce a contract or invalid shape, prefer a type-level check over duplicating that assertion in runtime tests.
• Keep modules small for agent context safety:
  • target <= 300 LOC per implementation file when practical.
  • if a file grows past 500 LOC, plan/extract focused submodules before adding new behavior.
  • if a file grows past 1,000 LOC, treat it as architecture debt unless it is generated data, a fixture snapshot, or an integration test aggregation.
  • long guidance/data tables should live behind focused modules instead of sharing a file with parser/runtime logic.
  • prefer deep modules over mechanical splits: extract when it improves locality for a concept callers already need, not just to reduce line count.

Tightening Pass

• Before finalizing a code change, do one scoped cleanup pass over touched and directly adjacent areas.
• Drop dead or obsolete code, redundant tests, stale helpers/fixtures, and needless duplication made unnecessary by the change.
• Prefer an existing helper over a new one; add a helper only when it reduces real repetition or clarifies domain behavior.
• Simplify control flow and types when the change makes defensive branches or compatibility shims unnecessary.
• Do not expand into unrelated refactors. If cleanup is valuable but broader than the task, note it as a follow-up.

Context Management

• Optimize for one-pass agent reads. A module that requires reading many siblings to understand one change is usually too shallow; a module that hides one concept behind a small interface is usually worth keeping.
• Start with the owning module, then one shared helper, then one downstream caller or adapter. Broaden only when the contract crosses that edge.
• Use targeted symbol searches before opening large files. For files over 500 LOC, search for the relevant type/function/section first, then read a bounded range.
• Do not add unrelated exports just to make tests easier. Test through the public interface when possible; if that is awkward, consider whether the module's interface is too shallow.
• When adding new guidance, examples, schemas, or command metadata, decide whether it belongs in the command surface, CLI grammar, CLI help, MCP projection, or daemon runtime before editing.
• Prefer updating existing domain vocabulary in CONTEXT.md when naming a new durable module concept. Do not coin parallel names in docs, tests, and code.

Routing

• Keep src/daemon.ts as a thin router.
• Keep command names centralized in src/command-catalog.ts; do not re-create command identity sets in handlers or request policy modules.
• Keep daemon routing and request-policy traits centralized in src/daemon/daemon-command-registry.ts; request modules should consume its predicates instead of recreating command string sets. See docs/adr/0003-daemon-command-registry.md.
• Keep command input/output contracts in the command modules:
  • command surface and shared schemas: src/commands/command-surface.ts, src/commands/command-contract.ts, src/commands/command-input.ts
  • typed client command execution: src/commands/client-command-contracts.ts
  • command families: src/commands/interaction-command-contracts.ts, src/commands/batch-command.ts, with other typed client contracts in src/commands/client-command-contracts.ts
  • CLI positional/flag grammar: src/commands/cli-grammar.ts and src/commands/cli-grammar/*
  • typed input to daemon request projection: src/commands/command-projection.ts
  • CLI/client/runtime output projection: src/commands/cli-output.ts, src/commands/client-output.ts, src/commands/runtime-output.ts
• Do not reintroduce CLI-shaped command adapters or schemas as a second source of truth. CLI, Node.js, and MCP should project from command contracts.
• Keep src/daemon/request-router.ts as request orchestration: auth, diagnostics scope, request admission, locking, handler chain, and fallback dispatch.
• New daemon handler-family commands must update src/daemon/daemon-command-registry.ts with the route and request-policy traits. src/daemon/__tests__/daemon-command-registry.test.ts guards route and policy traits; handler catalog tests keep executable handler sanity checks.
• Put request policies in focused request modules:
  • tenant/lease/selector/lock admission: src/daemon/request-admission.ts
  • artifact/error finalization: src/daemon/request-finalization.ts
  • request-scoped platform provider scoping: src/daemon/request-platform-providers.ts
  • generic fallback dispatch + action recording: src/daemon/request-generic-dispatch.ts
  • recording invalidation health: src/daemon/request-recording-health.ts
• Put command logic in handler modules:
  • session/apps/appstate/open/close/replay/logs: src/daemon/handlers/session.ts
  • click/fill/get/is: src/daemon/handlers/interaction.ts
  • snapshot/wait/alert/settings: src/daemon/handlers/snapshot.ts
  • find: src/daemon/handlers/find.ts
  • record/trace: src/daemon/handlers/record-trace.ts
• Commands routed as generic in src/daemon/daemon-command-registry.ts fall through to daemon fallback dispatch after specialized handlers return null.

Toolchain Snapshot

• Package manager: pnpm only. Do not add or restore package-lock.json.
• Packaged installs use ~/.agent-device as the implicit daemon state dir. Source checkouts default to a worktree-scoped daemon state dir under ~/.agent-device/dev/<basename-slug>-<hash> so local branches do not block each other. Use pnpm daemon:state-dir to print the effective path for the current worktree; --state-dir and AGENT_DEVICE_STATE_DIR remain authoritative overrides. Daemons are isolated by worktree, but devices are not; target different devices or simulators when running multiple worktrees concurrently. After pulling the worktree-scoped daemon change for the first time, stop any legacy source-checkout daemon with AGENT_DEVICE_STATE_DIR=~/.agent-device pnpm clean:daemon. Worktree-scoped state dirs outlive deleted worktrees; run pnpm clean:daemon --prune-dev occasionally (for example after deleting worktrees) to remove dirs under ~/.agent-device/dev/ with no live daemon and no activity for 14 days — it prints one line per removed dir and never touches the global ~/.agent-device root contents.
• Runtime baseline is Node >= 22. Prefer built-in Node APIs such as global fetch, Web Streams, and AbortSignal.timeout over compatibility wrappers unless the surrounding code needs a lower-level transport.
• Lint/format stack is OXC:
  • config: .oxlintrc.json, .oxfmtrc.json
• TypeScript is strict enough to surface dead code early: strict, isolatedModules, noUnusedLocals, and noUnusedParameters are enabled.
• The repo emits with rslib, not tsc. If declaration generation fails, inspect tsconfig.lib.json first.
• tsconfig.lib.json needs an explicit rootDir: "./src" for declaration layout.
• Use the aggregate scripts in package.json when possible; they encode the expected validation bundles better than ad hoc command lists.

Cheap Exploration

• Prefer these first-pass commands over broader reads:
  • rg -n "<symbol|command|flag>" src test
  • rg --files src/daemon/handlers src/platforms/ios src/platforms/android
  • git diff -- <path> for active-branch context
  • read .oxlintrc.json before treating lint output as source-level bugs
• If build/type errors mention declaration generation, inspect tsconfig.lib.json before reading platform code.
• If lint failures appear after toolchain edits, check whether the rule is from eslint/*, typescript/*, import/*, or node/* in .oxlintrc.json before assuming source bugs.

Command Family Lookup

• logs: src/daemon/handlers/session.ts -> src/daemon/app-log.ts -> src/daemon/handlers/__tests__/session.test.ts
• open/close/replay/apps/appstate: src/daemon/handlers/session.ts -> src/daemon/session-store.ts -> src/daemon/handlers/__tests__/session.test.ts
• click/fill/get/is: src/daemon/handlers/interaction.ts -> src/daemon/selectors.ts -> src/daemon/handlers/__tests__/interaction.test.ts
• snapshot/wait/settings/alert: src/daemon/handlers/snapshot.ts -> src/daemon/snapshot-processing.ts -> src/daemon/handlers/__tests__/snapshot-handler.test.ts
• record/trace: src/daemon/handlers/record-trace.ts -> src/platforms/ios/runner-client.ts -> src/daemon/handlers/__tests__/record-trace.test.ts

iOS Runner Seams

• Keep dependency direction clean:
  • runner-client.ts: command execution + retry behavior
  • runner-transport.ts: connection/probing/HTTP transport
  • runner-contract.ts: shared RunnerCommand type and runner connect/error helpers
  • runner-session.ts: session lifecycle and request/response execution
  • runner-xctestrun.ts: xctestrun preparation/build/cache logic
• runner-transport.ts must not import back from runner-client.ts.
• If changing runner connect errors, retry policy, or command typing, start in src/platforms/ios/runner-contract.ts before touching client/transport files.

Adding a New CLI Flag

A new snapshot/command flag touches only the layers that need to understand it. Follow this checklist in order:

1. src/utils/cli-flags.ts: add to CliFlags, FLAG_DEFINITIONS, and the relevant exported flag group (e.g. SNAPSHOT_FLAGS). Add the flag to CLI_COMMAND_OVERRIDES in src/utils/cli-command-overrides.ts for each command that supports it; command names/descriptions come from command contracts unless CLI help needs a specific override.
2. src/commands/cli-grammar/*: read the CLI flag into command input when the CLI accepts it.
3. src/commands/command-projection.ts and command-family projection helpers: write the input into the daemon request only if the flag affects daemon execution.
4. src/commands/*-command-contracts.ts: add or update the command input schema only if the option should be available through Node.js or MCP as structured input.
5. src/client-types.ts: update the public typed client option only when the Node.js interface exposes the option.
6. src/client-normalizers.ts: update daemon flag normalization only when the request still needs a public-to-internal option translation.
7. src/daemon/context.ts and src/core/dispatch-context.ts: add the field only when it flows into platform dispatch.
8. Handler/platform modules: thread the option only after the command surface, grammar, and projection prove it belongs there.

Command-only flags (like find --first) that do not flow to the platform layer usually stop at steps 1-3.

Hard Rules

• Use process helpers from src/utils/exec.ts for TypeScript process execution: runCmd, runCmdStreaming, runCmdSync, runCmdBackground, and runCmdDetached. Do not import raw spawn/spawnSync outside src/utils/exec.ts; add or extend an exec helper instead. Plain .mjs packaging fixtures that cannot import TypeScript helpers should keep child-process usage local and prefer execFile/execFileSync over spawn.
• Use daemon session flow for interactions (open before interactions, close after).
• Every manual agent-device open must have a matching agent-device close before the agent finishes, using the same --session, --platform, --udid, and --state-dir flags.
• Use keyboard dismiss for iOS keyboard dismissal; it may tap safe native controls such as Done but must not fall back to system back navigation.
• Do not remove shared snapshot/session model behavior without full migration.
• Command/device support must come from src/core/capabilities.ts.
• Apple-family target changes must keep src/utils/device.ts, src/core/capabilities.ts, src/core/dispatch-resolve.ts, src/platforms/ios/devices.ts, and src/platforms/ios/runner-xctestrun.ts in sync.
• iOS simulator-set scoping is iOS-specific: do not let iosSimulatorDeviceSet hide the host macOS desktop target when --platform macos or --target desktop is requested.
• If Swift runner code changes, run pnpm build:xcuitest.
• Use inferFillText and uniqueStrings from src/daemon/action-utils.ts.
• Use evaluateIsPredicate from src/daemon/is-predicates.ts for assertion logic.

Logs Contract

• Logs backend/source of truth is src/daemon/app-log.ts.
• session.ts should orchestrate only (start/stop/path/doctor/mark), not duplicate backend logic.
• App logs are distinct from runner/platform output. Keep app/device log capture in app.log; Apple runner and xcodebuild subprocess output belongs in the session-scoped runner.log.
• Preserve external grep/tail workflow in docs/skills.

Diagnostics & Errors

• Diagnostics source of truth: src/utils/diagnostics.ts
  • withDiagnosticsScope, updateDiagnosticsScope, emitDiagnostic, withDiagnosticTimer, flushDiagnosticsToSessionFile
• Request diagnostics belong in sessions/<effective-session>/requests/<request-id>.ndjson once the effective session is resolved. The top-level daemon log is for daemon lifecycle/startup and pre-session failures.
• Session artifact paths are centralized in src/daemon/session-store.ts; do not hand-build session log paths in handlers.
• Do not add ad-hoc stderr/file logging where diagnostics helpers apply.
• Normalize user-facing failures via src/utils/errors.ts (normalizeError).
• Failure payload contract: code, message, hint, diagnosticId, logPath, details.
• User-facing errors should be short and actionable: say what failed, why when known, and how to recover. Put recovery steps in hint when the action is not obvious, for example restart/retry, use plain screenshot when AX state is unavailable, navigate with coordinates, or inspect logs.
• If an interaction unexpectedly takes 5+ seconds, inspect the relevant daemon log before attributing it to the app. Check the session --state-dir daemon.log or the failure logPath for runner restart, stale session recovery, AX failure, transport retry, or command timeout evidence.
• Preserve hint, diagnosticId, logPath when wrapping/rethrowing errors.
• --debug is canonical; --verbose is backward-compatible alias.
• Keep redaction centralized in diagnostics helpers.

Optional Optimizations

• Treat optional optimization calls such as cache/preflight/probe requests as best-effort unless the feature contract says they are required. If an optimization fails, times out, returns non-OK, or returns an unusable shape, prefer falling back to the existing required command path.
• Keep optimization timeouts shorter than the underlying operation timeout. A preflight should not consume the full budget for a later upload or command.

React Native Verification

• After changing runtime code exercised through bin/agent-device.mjs or the daemon, run pnpm build and pnpm clean:daemon before manual device verification so snapshots use current dist output.
• For Android RN/Expo/dev-client apps connected to any local Metro port, adb reverse tcp:<port> tcp:<port> is harmless and should be run before opening the app or URL on the emulator/device.
• In sandboxed agent environments, run manual agent-device CLI verification that starts the daemon outside the sandbox with escalation. The daemon binds localhost, and sandboxed runs can fail before any product code executes with listen EPERM: operation not permitted 127.0.0.1 or repeated Failed to start daemon/metadata cleanup messages. Do not spend time debugging those as agent-device regressions; rerun the same command with escalation. Unit tests, typecheck, lint, and build can stay sandboxed unless they need platform devices or network/listener access.

Manual Device Session Hygiene

• Treat every manually opened agent-device session as a resource that must be closed, including exploratory sessions and failed verification attempts.
• For experiments, use a purpose-specific session name and, when practical, an isolated --state-dir under /private/tmp when you need cleanup isolation beyond the current worktree's default daemon.
• Keep track of each opened session in the working notes. Before final response, close each one with the same flags used to open it.
• If close or a later command is blocked by stale daemon metadata, inspect running processes first with ps -ax | rg "agent-device|xcodebuild test-without-building". Stop only exact stale PIDs that belong to the verification run, then run pnpm clean:daemon.
• If cleanup cannot be completed, report the remaining session name, state dir, process IDs, and metadata paths as a blocker.

Selector System Rules

• Interaction commands (click, fill, get, is) and wait accept selectors and @ref.
• Pipeline: parse -> resolve -> act -> record selectorChain -> heal on replay.
• Keep selector parsing/matching in src/daemon/selectors.ts.
• Call buildSelectorChainForNode after resolving target nodes.
• New element-targeting interactions must support selector + @ref, record selectorChain, and hook replay healing (healReplayAction in session.ts + selector helpers in session-replay-heal.ts).
• New selector keys remain centralized in selectors.ts.
• New is predicates belong in evaluateIsPredicate.
• On macOS, snapshot rects are absolute in window space. Point-based runner interactions must translate through the interaction root frame; do not assume app-origin (0,0) coordinates.
• Prefer selector or @ref interactions over raw x/y commands in tests and docs, especially on macOS where window position can vary across runs.

Shared Test Utilities

• Before writing a new test, check src/__tests__/test-utils/ for existing helpers:
  • device-fixtures.ts: canonical DeviceInfo constants (ANDROID_EMULATOR, IOS_SIMULATOR, IOS_DEVICE, MACOS_DEVICE, LINUX_DEVICE, etc.)
  • session-factories.ts: makeSession, makeIosSession, makeAndroidSession, makeMacOsSession
  • store-factory.ts: makeSessionStore (creates temp SessionStore instances)
  • snapshot-builders.ts: buildNodes, makeSnapshotState
  • mocked-binaries.ts: withMockedAdb, withMockedXcrun (stub CLI binaries for dispatch tests)
• Use import { ... } from '<relative-path>/__tests__/test-utils/index.ts' for convenient barrel imports.
• Prefer shared fixtures over inlining new DeviceInfo or SessionState objects in tests.
• Do not duplicate makeSessionStore, makeSession, or device constants when a shared helper already exists.

Testing Matrix

• Docs/skills only: no tests required unless a more specific rule below applies.
• CLI help/guidance changes in src/utils/cli-help.ts, src/utils/cli-command-overrides.ts, or src/utils/command-schema.ts: run pnpm exec vitest run src/utils/__tests__/args.test.ts.
• SkillGym prompt/assertion changes: run pnpm test:skillgym:case <case-id>; the script builds local CLI help first. For broad validation, use pnpm test:skillgym; append -- --tag fixture-smoke or -- --tag skill-guidance when validating one suite group.
• Non-TS, no behavior impact: no tests unless requested.
• Keep tests behavioral; do not assert shapes or cases TypeScript already proves.
• Any TS change: pnpm typecheck or pnpm check:quick.
• Fallow CI failures: reproduce with pnpm check:fallow --base origin/main instead of manually estimating complexity/dead-code impact.
• Test-only DI seam CI failures: the workflow enforces this; do not add optional typeof DI params in production code.
• Tooling/config change (package.json, tsconfig*.json, .oxlintrc.json, .oxfmtrc.json): pnpm check:tooling.
• Daemon handler/shared module change: pnpm check:unit.
• iOS runner/Swift change: pnpm build:xcuitest.
• Cross-platform behavior change: run pnpm test:integration.
• Any change in: src/, test/, skills/: pnpm format.

PR Readiness Checklist

• Static gates first: required checks from Testing Matrix pass, pnpm check:fallow --base origin/main is clean when code quality/dead-code risk is relevant, CI guards are green, and no conflict markers or unmerged paths remain.
• Command-surface changes preserve CLI, Node.js, daemon, MCP, help, docs, and SkillGym coverage where that surface is affected. Do not duplicate command contracts across layers.
• Device-facing behavior is not merge-ready until it has real simulator/emulator/device evidence for the changed path. Fixture-backed tests can prove contracts, but they do not replace a live run that creates or observes the artifact/state the feature claims to handle.
• If live verification is blocked, state the blocker, exact command or device needed, and downgrade the PR to residual risk instead of calling it ready.
• Runtime output must stay agent-friendly: compact defaults, top offenders first for diagnostics/perf, bounded arrays in JSON, artifact paths for large raw data, and progressive lookup for deeper detail.
• Before final response or PR handoff, close every manual agent-device session opened during verification and report any cleanup that could not be completed.
• Reviewers should check sibling PR ordering, hidden behavior changes, docs/help impact, and whether the tightening pass removed obsolete code/tests introduced or made unnecessary by the change.

Token Guardrails

• Do not read unrelated files once owning module is identified.
• Do not run integration tests by default.
• Do not inspect both iOS and Android codepaths unless task requires both.
• Prefer targeted git diff -- <paths> over broad file reads during review.
• Keep long help prose in src/utils/cli-help.ts; keep flag definitions in src/utils/cli-flags.ts; keep CLI-specific command usage/flag metadata in src/utils/cli-command-overrides.ts.
• Prefer snapshot -i, find, and scoped selectors over repeated full snapshot dumps when exploring Apple desktop UIs.
• Keep PR summaries short and scoped.

Common Mistakes

• Adding command logic to src/daemon.ts instead of handlers.
• Adding capability checks outside src/core/capabilities.ts.
• Inlining is predicate logic in handlers.
• Returning non-normalized user-facing errors.
• Duplicating logs backend logic in handlers instead of src/daemon/app-log.ts.
• Growing src/daemon/handlers/session.ts or src/platforms/ios/apps.ts further without extracting Apple-family/macOS-specific helpers first.
• Reintroducing an npm lockfile or assuming ESLint/Prettier still exist in this repo.
• Changing tsconfig.lib.json/build tooling without running pnpm check:tooling; declaration generation is stricter than tsc --noEmit.

Docs & Skills

• Versioned CLI help is the agent-facing source of truth. Put workflow guidance and help-topic prose in src/utils/cli-help.ts, keep flag definitions in src/utils/cli-flags.ts, keep CLI command overrides in src/utils/cli-command-overrides.ts, and assert important copy in src/utils/__tests__/args.test.ts.
• Keep parser schema and help rendering separate: src/utils/command-schema.ts composes contract-derived command schemas with CLI overrides; src/utils/cli-help.ts owns help topics and usage rendering.
• Skills are thin routers. Keep skills/**/SKILL.md focused on when to use the skill, version gating, which agent-device help <topic> page to read, and a short default loop. Do not duplicate full CLI manuals in skills.
• For behavior/CLI surface changes, update the versioned help instructions in src/utils/cli-help.ts or the CLI command metadata in src/utils/cli-command-overrides.ts, then assert important help copy in src/utils/__tests__/args.test.ts. Also update README.md and relevant website/docs/** when user-facing docs need it.
• For behavior/CLI surface changes and command-planning guidance changes, write or update a SkillGym case in test/skillgym/suites/agent-device-smoke-suite.ts that captures the expected agent command plan.
• Do not update skills/**/SKILL.md for command behavior or workflow guidance unless the user explicitly asks; skills must route to versioned CLI help instead of carrying behavior details.
• Keep SkillGym cases behavioral and command-planning oriented. Prefer prompts that assert the user-visible contract and expected command family over brittle exact output, but forbid known bad patterns.
• Use pnpm test:skillgym:case <case-id> for focused SkillGym validation; it runs the environment guard and builds local CLI help before skillgym run.
• Run SkillGym broad validation with pnpm test:skillgym; append v0.8 filters such as -- --tag fixture-smoke for focused suite groups.
• Preserve current high-value workflow guidance:
  • iOS Expo Go dogfood: prefer agent-device open "Expo Go" <url> --platform ios when the shell is known, then snapshot -i to confirm the project UI rather than the runner splash.
  • keyboard dismiss is the preferred iOS keyboard-dismissal path before manually pressing visible keyboard controls such as Done; it remains best-effort and can report unsupported layouts explicitly.
  • Empty replacement is not a supported clear-field command; do not document or test fill <target> "" as clearing. Prefer visible clear/reset controls or report the tool gap.
  • Mutating commands against one session must run serially. Parallelize only read-only commands or commands on separate sessions/devices.
• In final summaries, state whether docs/skills were updated; if not, explain why.

When Blocked

• If blocked by network/device/auth/permissions, stop and report:
  • blocker
  • why it blocks completion
  • exact next command/action needed to unblock

Pull Requests

• Before opening PR: ensure no conflict markers/unmerged paths.
• Commit messages and PR titles should use conventional prefixes such as feat:, fix:, chore:, perf:, refactor:, docs:, test:, build:, or ci: as appropriate.
• Do not use bracketed automation prefixes such as [codex] or similar bot tags in commit messages or PR titles.
• Open a ready-for-review PR by default. Use a draft PR only when the user explicitly asks for one or the work is intentionally incomplete.
• Run required checks for touched scope from Testing Matrix.
• PR body must be short and include:
  • ## Summary: lead with benefits and reviewer-relevant outcomes. Prefer a compact before/after when it makes the improvement clearer. Include the issue closed by the PR using Closes #123 when applicable.
  • ## Validation: answer this prompt in concise prose: "How did you verify the change, and what passed or changed on screen?" Prefer evidence over command dumps; mention the relevant check category or scenario, and include screenshots when visual/UI behavior is relevant.
• Call out real tradeoffs, known gaps, or follow-ups explicitly; omit boilerplate when there are none.
• Include touched-file count and note if scope expanded beyond initial command family.

Priority Order

• When guidance conflicts, apply in this order: Hard Rules -> Scope -> Testing Matrix -> style/preferences.
