pj	76dce1a75e	experiment instrumentation: step budgets, arm labels, campaign runner (#72) ... * feat(cli): add --max-steps for step-bounded runs runner.Options.MaxSteps already worked but was unreachable from the command line. A step budget is what makes two generators comparable: one making a model call per step and one drawing from a PRNG are not comparable per second. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * feat(trace): record arm membership and host in meta.json meta.json recorded the seed but not which picker ran, how it was configured, what budget it was given, or which machine produced it. A directory of runs cannot be attributed to an experiment cell without those, which makes any factorial computed from such a directory unanalysable after the fact. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * feat(cli): add --arm and populate run meta from it Model and instructions are recorded only when the LLM picker is the one that will actually run, so a spec declaring generator = llm() that is run under the seeded picker does not label its trace with a model it never called. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * feat(campaign): sweep seeds for one experiment cell campaign.json lists the seeds a sweep intended to run and is written before the first run, so a host that dropped runs shows up as missing seeds rather than as a smaller sample. Seed 0 is rejected: sanderling test reads it as "derive a seed from the clock", which is why conformance/gates.sh controls nothing today. Each run contributes one runs.jsonl line carrying steps to first violation by origin step, the step that armed the failed obligation, so the survival analysis never reopens a trace. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * fix(runner): no silent generator fallback, and llm on web --generator llm against a spec declaring no generator = llm(...) logged a warning and ran the seeded picker. For a comparison campaign that is silent arm corruption: the run completes, the directory looks correct, and the wrong policy drove it. It is now fatal. pickSources also returned the V8 source for both action and extractor on web before it looked at the generator, so the llm policy was unreachable there. The two axes are now independent: the driver picks the extractor source, the flag picks the action source, and llmSource composes with either because the runner populates the candidate list and screenshot on every platform. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * fix(chrome): make the hierarchy dump agree with the web runtime Three facts differed between the dump the goja host reads and the DOM the V8 host reads, so the two enumerated different candidates on one page. scrollable was never emitted, and worker.go reads exactly that attribute while targets.ts requires it for scrolls, so the goja host could not offer a single web scroll. clickable tested el.onclick, which React assigns to its root container for event delegation, making the whole viewport a tap target here and in no other enumeration. Both now resolve through the selector sets in pkg/spec/src/web-runtime.ts. The dump also rooted at body while collectTargets walks querySelectorAll("*"), so the goja host never saw html, where page-level scrolling lives. It now roots at documentElement and skips the head subtree, which is all zero-bounds and would otherwise carry script and title text into the trace. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * fix(conformance): give the gate reproducible seeds SEED defaulted to 0 and sanderling test reads --seed 0 as "derive a seed from the clock", so the tunable controlled nothing and a gate failure could not be re-run. SEEDS now takes one explicit non-zero seed per run, recorded in the results table so a failing row names its stream. The five runs stay on five different streams: a gate that scored one path five times would catch less than one that scores five. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * fix(chrome): emit editable as a plain boolean editable was emitted as `isEditable || null`, and an absent field sends internal/hierarchy into the native fallback, which reads any class name containing "EditText" as an Android text widget. On web that is just a CSS class, so a page styling a div with it was editable to the goja host and not to the web runtime, and the model policy could be offered typing into a div. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * fix(spec): leave the head subtree out of the web target walk collectTargets walked querySelectorAll("*") while the hierarchy dump skips head, so the two hosts enumerated different element sets on every page with a <head>. No candidate changes: builtinCandidates pushes only for targets acceptsTarget admits, and head elements have no positive bounds, so the list the draw ranges over is untouched. What changes is that targetIndex now means the same thing on both hosts. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * test(chrome): compare the facts both hosts derive from one DOM The existing parity harness hand-authors the facts on both sides, so it proves that given identical facts both hosts select identical candidates, and says nothing about the two code paths that derive those facts from a real page. Four divergences lived in that blind spot and it passed throughout. This drives one real page and compares clickable, enabled, editable, scrollable and positiveBounds element by element, plus the element sets themselves, which is what catches a host that omits html or includes head. Reverting any of the four fixes makes it fail naming the element and the fact. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * chore(make): run the browser packages one at a time Both launch Chrome and launching two at once has failed with "Launch: context canceled". Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * style: remove every em-dash and en-dash Eighteen occurrences across fourteen files. Each sentence was repunctuated to suit what the dash was doing rather than swapped for a hyphen, which produces comma splices. The minus sign in folio-web's ledger is a minus sign and stays. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * fix(chrome): honor the caller context in Launch Launch and clearState ran against d.tabCtx, so a target that accepts the connection and never answers wedged the process past its own --duration and through SIGTERM, needing SIGKILL. Unattended that is a campaign worker lost for the rest of the sweep with no diagnostic. The browser is still allocated against d.tabCtx first, because chromedp starts Chrome under whichever context calls Run first and allocating under a caller deadline would kill the browser when Launch returns. Everything after allocation goes through runCtx. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * fix(sidecarassets): publish the extracted jar through a rename Extract wrote a 96 MB jar with a plain WriteFile into a temp path every sanderling process on the host shares. On a cold host several concurrent workers all miss the checksum and all write the same path, and O_TRUNC lets one spawn a JVM against another's half-written archive. A fresh experiment host is exactly a cold host. Claude-Session: https://claude.ai/code/session_01A5KmftdEJ49A9z5mF5ESrX * feat(campaign): kill a run that outlives --run-timeout A wedged run holds its worker for the rest of the sweep, and on an unattended host nothing else will send it a signal. Defaults to three times --duration and must exceed it. A killed run is recorded as timed_out rather than as a generic failure, so the analysis can tell a lost cell from a real crash.

pj	c5bb176be8	UX refactor (#52) ... * feat(ltl): bound fields on AlwaysFormula and named thunks Add StepBound/Duration/Deadline to AlwaysFormula as the dual of bounded Eventually, give ThunkFormula a Name for stable identity, add ThunkNamed, and surface both in describe() and MarshalJSON. * feat(ltl): negation normal form pass nnf/pushNot rewrite a formula so every Not wraps only a Thunk or Error leaf, dualizing Always<->Eventually and preserving bounds. * feat(ltl): NNF in NewEvaluator, bounded-always, Finalize, collapse Apply nnf on construction, reduce bounded Always symmetric to bounded Eventually (vacuous holds once the window closes), add Finalize to resolve undischarged liveness obligations to Violated at run end, and collapse structurally-identical pending obligations. * test(ltl): property-based NNF laws Lock double-negation identity, Always/Eventually duality with bound preservation, leaf pushdown, and not(always true) reaching Violated. * test(ltl): Finalize, bounded eventually, latch, collapse Property tests for monotonic violation latch and eventually-within violating iff n consecutive false, plus Finalize and collapse cases. * feat(inspect): within clause on always residual node A negated bounded eventually serializes as a bounded always; render its bound instead of dropping it. * feat(ltl): witness violations and (bool,error) predicate thunks * test(ltl): migrate thunk call sites to (bool,error) * feat(ltl): flag thrown-predicate witnesses with IsError * refactor(verifier): replace predicate err side-channel with violation witness * test(verifier): witness API for thrown predicates * feat(trace): witnesses map and skipped-verification marker on Step * feat(runner): thread violation witnesses, finalize, skip marker into trace * test(ltl): lock violation witness reason, IsError, and step * test(verifier): finalize surfaces unmet eventually with witness * fix(ltl): eliminate implies and bounded-always false-negatives Rewrite a -> b to (not a) or b in NNF so a pending temporal antecedent can no longer defer the whole implication and drop a consequent that was false at the current step. Carry a pending inner past a bounded-Always window close instead of dropping it to holds, so a deferred obligation is resolved by a later step or Finalize. * test(ltl): lock implies and bounded-always false-negative regressions * fix(web-runtime): seed PRNG for reproducible runs and align weighted pick * feat(testrun): inject seed into web bundle via SANDERLING_SEED define * test: cover web-runtime seeded PRNG, weighted pick, and seed define wiring * test(spec): add Go math/rand/v2 PCG oracle and golden fixture * feat(spec): bit-exact PCG port of Go math/rand/v2 * test(spec): assert pcg.ts matches the PCG golden fixture * feat(spec): shared input corpus and press-key pools * feat(spec): action-tree types and Host interface * feat(spec): verb support matrix and warn-once helper * feat(spec): deterministic shared action picker * test(spec): verb matrix and warn-once semantics * test(spec): picker draw-order and determinism * refactor(spec): actions.ts returns pure GeneratorNode data trees * refactor(spec): wire from() sampling through the picker rng * feat(spec): shared runtime-entry installs next-action over pick.ts * feat(spec): export LongPress/Scroll/longPresses/scrolls factories * test(spec): assert data-tree shapes for action factories * test(spec): runtime-entry serializeAction wire-contract round-trip * refactor(spec): bridge data-tree nodes to the legacy goja picker tags * fix(spec): web runtime walks the spec's globalThis.actions data tree * test(spec): tolerate legacy bridge fields on builtin nodes * refactor(spec): installRuntime accepts a lazy root resolver The web bundle imports the runtime before the spec, so the action root on globalThis.actions only exists after the spec evaluates. Accept a function form so the goja and web hosts resolve the root per tick. * refactor(spec): web-runtime becomes the WEB Host, delegates to shared picker Delete the duplicate picker (resolveGenerator/pickWeighted/randomTap/ randomInput/randomSwipe/randomPressKey/pickFromArray, the mulberry32 PRNG, and the snake_case serializeAction) plus the __sanderling__ action factory binds. web-runtime now implements Host (platform/seedHi/seedLo from the injected 64-bit seed via BigInt, queryCandidates over the live DOM with a per-tick cache, reportUnsupported) and calls installRuntime so both engines run pick.ts over the same Pcg. Swipe/longPress/scroll follow the verbs.ts matrix instead of silently returning null. Keeps the DOM helpers (selector translation, queryElement, elementHandle, buildState, sanitize, extractors) and the global locking. Net -214 lines (741 -> 527). * test(spec): cover the WEB Host surface and seed precision Replace the deleted-picker tests with Host coverage: platform()==web, seedHi() parsing a 64-bit seed without Number precision loss, seedLo()==0, reportUnsupported warning, the installed next-action/extractor globals, and queryCandidates verb routing + per-tick caching over a querySelectorAll stub. * refactor(spec): picker emits native selector + scroll endpoints, setup precedence * feat(spec): goja runtime entry wires the shared picker over the Go host * feat(bundler): optional RuntimeFile prepends a runtime-entry import via stdin * feat(testrun): bundle the goja runtime entry so the verifier runs the shared picker * refactor(spec): drop the legacy goja bridge fields from action factories * feat(spec): serialize selector-only string targets for the runner to re-resolve * refactor(verifier): one DecodeAction reads the unified flat wire contract * refactor(verifier): goja host + shared picker replace the duplicate Go picker * refactor(runner): decode V8 actions via the unified DecodeAction; wire goja runtime * test(verifier): author specs through the shared picker path * test(runner): bundle authored specs with the goja runtime entry * feat(verifier): collect unsupported verbs for the run report * refactor(runner): collapse WebDriver forks behind ActionSource/ExtractorSource * feat(testrun): surface unsupported verbs in run report * test(verifier): cross-runtime goja/node parity gate on the shared picker * test(verifier): unsupported verbs collected deduped in first-seen order * test(runner): summary reports no unsupported verbs on a clean run * test(spec): golden-fixture cross-runtime parity gate for the node picker Replace the env-driven parity harness with a shared scenario module and a committed golden the node picker asserts independently. The goja side asserts the same golden, so neither runtime invokes the other at test time. * test(verifier): assert goja picker against the same cross-runtime golden Drop the node-subprocess coupling: the goja side now installs a stub __sanderlingHost__ with the fixed candidate list and asserts the committed golden, matching pkg/spec/test/parity.test.ts. * refactor(spec): rename pressKey generator export to pressKeys * refactor(spec): update barrel re-exports for pressKeys * test(spec): update pressKeys generator export name * docs(spec): rename pressKey generator to pressKeys * refactor(spec): extract samplerRng into shared sampler-rng module * feat(spec): add fluent seeded value generators (strings/integers/emails/edgeCaseText) * test(spec): cover fluent value generators determinism and chaining * refactor(bundler): inject globalThis trailer from spec named exports * refactor(bundler): reuse registration trailer in web bundler * test(bundler): cover named-export globalThis registration * feat(spec): add named() to Extracted handle type * feat(web-runtime): named() and cross-extractor read guard * feat(verifier): named() and cross-extractor read guard in goja * test(verifier): cross-extractor read guard and named() * test(web-runtime): export runtime and extractors for tests * test(web-runtime): named() and cross-extractor read guard * refactor(folio): drop manual globalThis trailer (bundler injects it) * refactor(folio): seed txn amounts via integers().between(1,500) * refactor(folio-web): drop manual globalThis trailer (bundler injects it) * fix(folio-web): seed card/txn-type selection via from().generate() for reproducible runs * refactor(folio-web): weight valid generators against edgeCaseText for names/amounts * refactor(folio-web): name extractors so violation witnesses are readable * fix(web-runtime): propagate extractor getter throws and unpoison locked global Stop swallowing getter errors in evaluateExtractors so the cross-extractor read guard aborts loudly, matching goja's PushSnapshot. Make the __sanderling__ lock configurable (still non-writable) so a shared test process can reinstall a fake. * test(spec): install fake runtime via defineProperty to survive locked global * test(web-runtime): assert uncaught cross-extractor read aborts evaluateExtractors * feat(runner): add MaxSteps bound to Options * test(runner): MaxSteps stops after exactly N steps * test(driverpb): drop proto getter round-trip tautology * test(sidecar): drop stub-mode placeholder tautology tests * test(mock): drop default-field-value assertion test * test(ltl): drop Verdict.String tautology tests * refactor(runner): extract RenderSummary for snapshot testing * test(runner): golden snapshots for trace stream and violation summary * feat(web-runtime): capture uncaught errors into state.exceptions * test(integration): add throwing and counter web fixtures * test(integration): add specs for the web fixtures * test(integration): drive web fixtures through the real pipeline in headless Chrome * chore(make): add test-browser target for the Chrome-driven suite * ci: run the Chrome-driven browser suite in a separate job * refactor(test): relocate browser suite to test/browser * refactor(permissions): delete dead internal/permissions package * refactor(test): rename package to browser_test * refactor(sidecarassets): rename internal/sidecar to internal/sidecarassets * chore(make): point test-browser at test/browser * docs(decisions): record internal/permissions deletion * refactor(doctor): use sidecarassets package * refactor(testrun): use sidecarassets package * fix(test): resolve testdata relative to browser_test.go * refactor(verifier): remove dead __sanderlingIndex compat alias * refactor(bundler): use encoding/json for JS string literals * docs(action-space): use vendor-neutral native driver wording * refactor(hierarchy): scrub backend tool name from comments * refactor(driver): scrub backend tool name from comments * refactor(driver): add DoubleTap and DoubleTapSelector to DeviceDriver * refactor(sidecar): implement DoubleTap with the sub-100ms inter-tap gap * refactor(chrome): implement DoubleTap as two taps with the gap * refactor(mock): record DoubleTap and DoubleTapSelector actions * refactor(runner): delegate double-tap to driver, drop gesture timing * test(runner): assert double-tap delegates to driver DoubleTap * docs(cmd): add package docs to CLI and developer tools * docs(driver): add package docs to driver interface and chrome backend * docs(driver): add package docs to mock and sidecar backends * docs(platform): add package docs to android and ios device prep * docs: add package docs to bundler and inspect * docs(ltl): add package doc to temporal logic evaluator * docs: add package docs to runner and testrun pipeline * docs: add package docs to trace and verifier * docs(sidecarassets): add package doc for embedded JAR loader * fix(chrome): add disable-dev-shm-usage so Chrome starts in CI * test(chrome): gate real-Chrome driver tests behind the browser tag * chore(make): run chrome driver tests in the browser job * fix(web-runtime): guard global error listeners for non-browser hosts The module registered window error/unhandledrejection listeners at top level, which threw under Node (the spec-api test runner) where globalThis.addEventListener is absent. Register only when the API exists; the real browser run is unaffected. * ci(browser): re-enable unprivileged user namespaces for headless Chrome ubuntu-latest moved to 24.04, whose AppArmor restriction on unprivileged user namespaces stops headless Chrome from opening its DevTools socket even with --no-sandbox, surfacing as the driver's 'websocket url timeout'. Relax the sysctl for the job and add a direct launch check so a future breakage shows Chrome's own stderr rather than an opaque driver timeout. * ci(browser): pin stable Chrome for the driver tests setup-chrome's default latest pulled a dev Chromium (150) whose remote debugging socket never came up under chromedp, while plain --dump-dom worked. Pin the stable channel, which the driver is tested against. * feat(defaults): add scroll and rebalance action weights Use relative-integer weights (taps/typing co-primary 100, scrolls 50, swipes 25, doubleTaps 10); the picker normalizes by their total. Adds scrolls to defaultActions as a first-class reveal behavior. * feat(defaults): trim scroll action weight wiring * fix(build): point sidecar jar ignore and embed paths at sidecarassets * test(defaults): drop stale longPresses re-export assertion longPresses is opt-in vocabulary, no longer re-exported from defaults/actions.ts since e0d3b20; its builtin resolution is already covered by api.test.ts. Trim the defaults test to scrolls, which is an actual default export. * fix(chrome): raise DevTools websocket read timeout to 60s Chrome cold-start on a loaded CI runner can exceed chromedp's 20s default for reading the DevTools websocket URL, flaking the browser tests with "websocket url timeout reached". Give launch more headroom.	2026-06-02 09:52:53 +05:30
