"""ARRFLIX headless smoke-test v2.

Why v2 exists (see docs/26 INC4 audit):
  v1 had three coverage gaps that let two regressions ship:
    - Logged in only as `guest` (non-admin restricted) → admin-only sections
      like the "More from Season N" carousel never rendered, so the black
      band behind that carousel was invisible to the test.
    - Never clicked Play → never observed the <video> element in a real
      playback state, so AV1+Opus episodes silently rendering black went
      undetected.
    - Probed only a hardcoded selector list → any element painting an
      opaque background outside that list (e.g. a new section wrapper)
      was never reported.

v2 closes those gaps:
  1. Multi-user runs: executes the full probe as BOTH admin and non-admin
     in the same invocation, writes per-user JSON + screenshots, and
     reports a DOM-section diff (sections present for one user but not
     the other → admin-only-visible content).
  2. Click Play: locates the play button, clicks it, waits 10 s, captures
     <video> element state (currentTime, paused, error, readyState, dims),
     plus a video-area screenshot and any new console / network errors.
  3. Multiple-item coverage: walks an item list (default: HEVC movie + AV1
     TV episode + H.264 TV episode if available) and runs the full
     detail-page + play probe for each.
  4. Section-bg sweep: at scroll-bottom, walks every visible element and
     reports any with a non-transparent backgroundColor whose bounding rect
     overlaps where the pinned backdrop should be visible. Output goes
     into probe.json under "regressions" with an allowlist filter.
  5. Golden-screenshot diff: if a known-good screenshot exists at
     OUT/golden/<key>.png, the run computes a Pillow pixel diff and writes
     <key>-diff.png + a numeric mismatch ratio.
  6. Structured JSON: probe.json now has top-level shape
       {url, runs:[{user, item, item_kind, probe, play, regressions, ...}]}
     so downstream tooling (CI / agents) can parse without grepping.

Usage:
  bin/headless-test-v2.py [URL] [OUT_DIR]

  URL defaults to https://dev.arrflix.s8n.ru.
  OUT_DIR defaults to /tmp/arrflix-headless-v2.

  User credentials are determined automatically from URL:
    arrflix.s8n.ru     → admin=s8n / guest=guest
    dev.arrflix.s8n.ru → admin=s8n-dev / guest=guest-mirror

  Override via env vars:
    ADMIN_USER, ADMIN_PASS, GUEST_USER, GUEST_PASS
    ITEMS=id1,id2,id3   # override default item list

Default items (chosen for codec coverage):
  - HEVC movie:    7aa5add2c2d8575eda5280b9b9072071  (The Dark Knight)
  - AV1 episode:   auto-pick first Mike Nolan Show episode
  - H.264 episode: auto-pick first non-AV1 episode if available

Exit codes:
  0  all runs succeeded, no playback errors, no regression bg elements
  1  setup / login failure
  2  one or more runs reported playback failure or unallowlisted bg regression
