* chore(docs): replace d2 diagram pipeline with mermaid
Remove docs/_diagrams/ and d2 build step from Makefile. The HTML
template already initialises mermaid.js; diagrams are now inline
code fences rendered client-side.
* docs(architecture): add mermaid diagram + web/CDP platform docs
Replace SVG img tag with inline mermaid flowchart showing both native
(Maestro sidecar + in-app SDK) and web (Chrome CDP) paths. Update
Processes, Transports table, and per-step cycle sections.
* docs(design-principles): update principles 1-4 for web platform
Principles 1, 2, 3, and 4 referenced Maestro and native-only concepts.
Add web/CDP context and update driver-is-an-interface to name both
sidecar and chrome implementations.
* docs(manual): add web prerequisites and folio-web example
Update --platform flag to list android, ios, web. Add web prerequisites
section (Chrome, no SDK needed) and folio-web quick-start to
getting-started.
* chore(gitignore): untrack inspect dist/index.html build artifact
index.html is regenerated by vite on every build with a new content hash,
making it permanently dirty. Only .gitkeep is needed for //go:embed to
compile on a fresh checkout. Also remove duplicate dist/* line and stale
d2 diagram ignore entries.
* feat(docs): click-to-zoom for mermaid diagrams
* docs(architecture): change diagram layout from LR to TB
* docs(getting-started): link npm and Maven Central package headers
* update docs root
* docs(spec): rewrite npm package README
Update usage example to current API, drop stale version-compatibility
and license sections.
* build(docs): output pages as pagename/index.html for clean URLs
Split DOCS_OUT into INDEX_OUT (index.md files stay as index.html) and
PAGE_OUT (all other pages become pagename/index.html). The __ROOT__
depth computation already handles the extra directory level correctly.
* chore(docs): update sidebar links to directory-style URLs
* docs: update cross-links from .html to directory-style paths
* ci(docs): remove d2 install step
* feat(docs): dark/light mode toggle
Add theme toggle button (top-right, fixed). Persists preference in
localStorage; falls back to prefers-color-scheme. Flash-free via inline
script in <head> that sets data-theme before first paint.
* fix(docs): fix inspect image path broken by directory URL restructure
* feat(docs): click-to-fullscreen for all article images
* fix(inspect): allow AssetsFS override in ServerOptions; drop unused request param from serveIndex
* fix(inspect): use in-memory FS in tests so TestAssets_FallbackToIndexHTML passes without web build
* feat(ltl): add Now/Next/Eventually/Implies/Or/And/Not formulas
Replace the fold-with-latch evaluator with a residual-formula reducer.
Each Observe() instantiates a fresh obligation from the root (stripping
an outer Always), reduces each pending obligation against current state,
latches Violated on first failure, and surfaces Pending verdicts for
deferred obligations. Existing Always/Pure/Thunk tests continue to pass.
* feat(ltl): support relative duration for eventually().within()
* feat(proto): add Swipe, PressKey, RecentLogs RPCs
* feat(verifier,runner): formula handles, new action kinds, rich state
- verifier: add formula-spec registry; bindNow/bindNext/bindEventually with
chainable .implies/.or/.and/.not and .within(n,unit) on eventually; bindFrom
for uniform sampling. bindAlways keeps accepting plain predicates.
- verifier: store lastTree, lastAction, step time, logs, exceptions on the
Verifier; SnapshotInput replaces the (snapshots, tree) pair. stateObject now
produces state.lastAction/time/logs/exceptions matching the TS State type.
- verifier: make taps/swipes/waitOnce/pressKey built-in generators actually
fire; taps picks a clickable, enabled element from the last hierarchy.
- agent: add exceptions field to Message wire format.
- driver: add Swipe/PressKey/RecentLogs to Driver interface; wire maestro
client and mock driver. LogEntry exposed for runner consumption.
- runner: apply Swipe/PressKey/Wait actions; collect logcat and exceptions;
pass lastAction and step time into PushSnapshot.
* feat(spec-api): LTL operators, new actions, richer State
- ltl.ts exports now/next/eventually; always overload accepts a Formula
- types.ts: Formula gains implies/or/and/not; EventuallyFormula adds .within;
State gains lastAction/time/logs/exceptions; Swipe/PressKey/Wait action types
- actions.ts: Swipe/PressKey/Wait/from constructors; waitOnce + pressKey
default generators
- tests exercise the chaining, sampling, and new actions through a recorded
fake runtime
* feat(sidecar): add swipe, pressKey, recentLogs RPC handlers
* feat(sdk-android): capture uncaught exceptions
Install a default uncaught handler on Uatu.start, chained with any
existing handler so Android's crash reporter still runs. Expose
Uatu.reportError for callers to forward caught throwables. A bounded
circular buffer (default 50) drains into each STATE message's new
exceptions field. Protocol.kt serializes/deserializes the field,
matching the Go wire format added to internal/agent/protocol.go.
* feat(spec-api): add @uatu/spec/defaults/properties bundle
* feat(sample-app): exercise new LTL operators + defaults
spec.ts now imports eventually/next/now/from from @uatu/spec and
noUncaughtExceptions from @uatu/spec/defaults/properties. It declares
three properties that exercise the new surface:
- accountCountNonNegative: plain always() safety
- addAccountAdvances: always(now(x).implies(next(y)))
- eventuallyLoggedIn: eventually(p).within(30, "seconds")
- noUncaughtExceptions: imported default
The weighted actions root uses from() for random phone/name sampling
and entries for taps/swipes/waitOnce/pressKey built-ins.
SampleApplication gains a debug hook gated on the system property
uatu.inject_error so the e2e run can synthesize an Uatu.reportError and
verify noUncaughtExceptions violates.
cmd/uatu/test_run.go adds a subpath alias so specs importing
"@uatu/spec/defaults/properties" resolve against the in-tree source
when running from the uatu checkout. The spec-integration tests swap
the old click-counter fixtures for the new login hierarchy.
* feat(trace): record swipe/key/wait details + exceptions
trace.Step gains an Exceptions array so the trace captures the
class/message/stackTrace for each SDK-reported throwable in a step.
trace.Action gains FromX/FromY/ToX/ToY/Key/DurationMillis so the full
payload of Swipe/PressKey/Wait actions is visible in trace.jsonl.
sample-app's debug error hook now gates on ApplicationInfo.DEBUGGABLE
instead of a system property (adb setprop fails on non-rooted
emulators).
* feat(cli): add Version var and version subcommand
* build(gradle): introduce uatu.version property for lockstep releases
* build(sdk-android): swap GitHub Packages for vanniktech Maven Central plugin
* build(spec-api): make package publish-ready for npm
* ci(release): add goreleaser config for cross-platform uatu CLI builds
* ci: add ci and release GitHub Actions workflows
* ci: restrict ci.yml to PR + workflow_dispatch (no direct push to master)
* docs(release): add local release targets, env example, and install docs
* build(sdk-android): make signAllPublications conditional on signing key
* ci(release): stage sidecar JAR at embed path before go build
* chore(spec-api): regenerate package-lock for updated package.json
* ci: install protoc-gen-go plugins before buf generate
* ci: bump Node to 22 (required for --experimental-strip-types)
Thin wrappers over a globalThis.__uatu__ runtime that the verifier
provides as host bindings. Spec authors get IntelliSense for
extract/always/Tap/InputText/actions/weighted/taps/swipes, but the
bundle stays small because runtime logic lives in goja.
TypeScript 5.6 with strict mode, bundler module resolution. Tests
run via node --test --experimental-strip-types so we don't need
vitest or a build step. Adds node_modules to .gitignore.
