Web UI E2E compatibility contract

Machine inventory extracted from tests/browser_*.mjs by scripts/extract_webui_contract.mjs. Do not edit by hand — regenerate.

F-01 does not transplant app.js. It freezes the three surfaces the rewrite must keep green:

1. window globals → frontend/src/compat/window-exports.ts (F-05)
2. S field read/write, including nested writes after which tests call render functions synchronously → window.S Proxy (F-05); objects such as _timelineView keep reference identity
3. DOM id/class/attr selectors → class/id freeze (F-21)

Source files (sorted): - tests/browser_admission_fault.mjs - tests/browser_auth.mjs - tests/browser_matrix.mjs - tests/browser_p1_controls.mjs - tests/browser_sandbox_preview.mjs - tests/browser_smoke.mjs - tests/browser_stage0_acceptance.mjs - tests/browser_stage1_trusted_delivery.mjs - tests/browser_team_mode.mjs

1. Bare window globals

Free identifiers inside page.evaluate / waitForFunction callbacks on the main workbench page, minus locals, keywords, browser builtins, and absence probes. window.__* test hooks are omitted. Existing legacy-shell guards and iframe contexts are inventoried separately. Sorted by name.

Total names: 57

1a. Context-specific and optional globals

These uses keep their original harness checks. They are not required on the default workbench window: legacy blocks run only behind their existing shell guard, iframe calls run in that frame, and absence probes explicitly handle missing names. An unguarded main-page use is still required.

2. S field read/write surface

Top-level S.<field> accesses inside evaluate callbacks. Nested writes (S._timelineView.searchQuery = …, .collapsedTurns.add(...)) are listed under write paths so F-05 can keep object identity.

2a. Private S._* fields

S._* identifier occurrences: 127

2b. Other S.* fields

2c. Context-specific S accesses

These fields belong to the existing guarded or framed checks above; they do not require a signal on the default workbench S Proxy.

3. DOM selector contract

CSS selectors passed to locator, waitForSelector, querySelector, querySelectorAll, closest, matches, getElementById, and Playwright click / fill / textContent when the argument is a CSS selector. Template interpolations are normalized to *. Tag-only selectors without id, class, or attribute (for example script) are omitted. Sorted.

Total selectors: 217
