* refactor: declare selector resolution policy as data (#1630) Five native consumers of "resolve a selector against the screen" each hand-declared their ambiguity contract as inline requireUnique/ disambiguateAmbiguous literals, so the repo's real policy matrix was only discoverable by reading four files. SELECTOR_RESOLUTION_POLICIES (packages/selectors) now declares one row per caller — ambiguity kind plus the structural columns (rect, occlusion, off-screen guard, promotion, poll) — and selectorResolutionKnobs turns a row into the engine knobs it stands for. Callers consume rows; zero ambiguity literals remain in src. Semantics are unchanged by construction: each row was read off its call site. The matrix names what was previously implicit — act and get text disambiguate, is/get attrs fail closed, exists/find-reads and wait take the first match, mutating find rejects candidates unless narrowed (#1625). `reject-candidates` is declaration-only and rejected by selectorResolutionKnobs at the type level, because find enforces it through its own narrowing rather than engine knobs. resolution-policy-parity.test.ts gate-tests the matrix against the callers (ADR 0011's declared-plus-gate-tested pattern): knobs must match the named ambiguity contract, every claimed structural column must appear in the caller's source, the read/wait pipelines must genuinely lack the machinery they disclaim, and no caller may reintroduce an inline literal. Verified revert-sensitive: flipping readUnique to disambiguate and faking wait's occlusion column each fail it. Out of scope, unchanged, per the issue: the Maestro engine (ADR 0015) and the open click-implicit-wait product decision. * refactor: route wait and mutating find through the policy interface (#1649 review) P1 was right: the first head declared seven rows but genuinely routed five. selector-wait.ts never imported its row (it called listSelectorChainMatches directly), findAct consumed only requireRect while its ambiguity contract stayed bespoke, and the parity test sniffed marker strings in source files — so it stayed green across exactly that gap. Asserting about the layer I had edited instead of the behavior it produces. resolveSelectorChainWithPolicy is now the one policy-driven entry: it returns a discriminated outcome (none / resolved / ambiguous) because the rows genuinely disagree about what several matches mean, which is what previously forced each caller to re-derive its contract inline. wait and find's selector branch both route through it; find additionally asserts its row still says reject-candidates rather than assuming. The parity test is rebuilt on fixture trees driven through that interface — no source sniffing. Wiring verified revert-sensitive: flipping the wait row fails the policy tests, and flipping findAct fails REAL find handler tests (ambiguous-candidate listing), which is the proof the previous version could not produce. One behavior nuance the fixture work surfaced and now pins: disambiguation declines on genuinely indistinguishable candidates (the tiebreak is evidence, not a coin flip), so an acting row surfaces ambiguity there rather than binding one silently. * fix(test): let fallow see the host-process mock helper's real consumers Rebase onto main brought #1642's host-process-mock.ts into this PR's fallow scope, where its export reports as unused. It is not: three suites consume it, but only through `(await import(...)).pinOwnProcessStartTime` inside vi.mock factories — vitest hoists those above static imports, so the dynamic form is required and fallow cannot trace it statically. Documented suppression rather than a restructure that would break the hoisting contract. Latent on main rather than introduced here: the audit gate is changed-files-only, so main sees the file in scope only from a PR whose diff contains it. * fix: keep every candidate when a policy resolves one winner (#1649 review P1) A real regression I introduced, not a test gap: routing wait through the policy interface collapsed the candidate set to the winner, and the #1349 landmark check is satisfied when SOME match carries the recorded identity. A first same-selector impostor therefore hid a later genuine landmark and timed the wait out. The resolved outcome now carries `matchedNodes` — the full candidate set of the alternative the winner came from — so a policy that picks one node no longer throws the rest away. wait passes that straight to the landmark check, restoring the original semantics. Regression test added at the within-one-poll shape the existing suite did not cover (both candidates in the SAME capture, impostor first); verified it goes red against the singleton reconstruction it replaces. * refactor: declare only the policy fields the matrix enforces (#1649 review) The occlusion / offscreenGuard / promotion / poll columns were never consumed by resolveSelectorChainWithPolicy or selectorResolutionKnobs: changing any of them left behavior and the suite green, so they were unverifiable claims that read as truth. (My earlier source-sniffing test "verified" them by grepping caller files for marker strings — which is why it also stayed green when a row was disconnected entirely.) The matrix now declares exactly what it enforces: the ambiguity contract and the rect requirement, both consumed by the resolution interface and pinned behaviorally. A new test asserts every row's field set, so an unenforceable column cannot reappear without coverage — verified by re-adding one and watching it fail. Routing the structural stages into typed behavior is tracked in #1656 with the constraint that each field must be consumed, not merely declared. * fix(selectors): flatten the policy outcome at the package boundary `PolicyResolutionOutcome.resolution` was typed as `AstSelectorResolution` and the root façade returned it unchanged, so the parser AST #1589 confined to `@agent-device/selectors/ast` came back through a nested field. `selector-wait.ts` reading `outcome.resolution.selector.raw` was the runtime proof. The existing boundary gate reads exported *names*, so it could not see this. The public outcome now lives beside `SelectorResolution` in public-resolution-types.ts with its selector as text; the parser-side shape is renamed `AstPolicyResolutionOutcome` and stays package-private, and the façade wrapper flattens on the way out — the same treatment `resolveSelectorChain` already gave `AstSelectorResolution`. Two new pins, both verified red against the shape they replace: a behavioral one asserting the façade returns selector text under every policy row, and a structural one asserting resolution shapes are re-exported from public-resolution-types.ts rather than from a parser-side module — which is what distinguishes the leak from a correct re-export in a name list.
