Investigated with a real curl_cffi capture (HTTP 200, 46 cards): the Avito
SERP lazy-renders — data-marker="item-date" appears only on the top
above-the-fold cards (~10/46), so ~79% of cards have no date in the raw HTML
curl_cffi receives. The marker wasn't renamed; the field is just absent.
But every listing carries sortTimeStamp (epoch-ms) in the embedded per-item
JSON (56 occurrences/page) — the line-266 'state empty' note was stale. Map
item_id (= DOM data-item-id) -> sortTimeStamp -> date as the primary source,
keep the DOM item-date + _parse_relative_date as fallback for the top cards.
Verified on the real capture: 42/46 = 91% coverage (was ~21% DOM-only),
clearing the >80% DoD bar. Adds a distilled real-structure fixture
(avito_serp_sample.html) + unit test covering both the JSON (lazy card) and
DOM (top card) paths.
Refs #726
Add warm-up GET /evaluation/realty + production browser header set (Sec-Fetch,
X-Requested-With, 25s timeout) mirroring avito.py, чтобы защитить 3-step IMV flow
от server-IP анти-бот 403. Refactor step B/C парсинга в pure helpers
(_parse_geo_position/_parse_price/_parse_placement_history/_parse_suggestions)
+ fixture-driven offline тесты из живых JSON-captures.
Честный диагноз: контракт (geoFieldsHash, price-блок, categoryId=24) НЕ менялся —
проверено живым capture'ом с этой машины (A→B→C, recommended 7.39M). Реальная
причина #565 — скорее анти-бот по PROD-IP, не код → если #565 останется после
deploy, настоящий фикс = ротация egress IP воркера (devops, отдельно).
code-reviewer: ✅ APPROVE no critical — warm-up non-fatal, injected-session path
unchanged, refactor preserves shapes, graceful-None сохранён, fixtures без PII.
Tests: 12 new (27 total). Ruff clean.
Closes#565
Avito switched the houses-catalog state blob from JSON.parse("<js-escaped>")
to a URL-encoded string literal, wrapped the 10 widgets in
placeholders[0].widgets, и re-nested developmentData под props.housePage.
JS-unescape path silently failed → houses rows перестали наполняться
(starve'ит #6 same-building + #569 deal centroids).
Extract decode в pure _extract_preloaded_state (urllib.parse.unquote,
JSON.parse fallback для старой формы), add _flatten_widgets, и сделать
_parse_house_page tolerant к обеим developmentData/ratingPreview формам.
Real-HTML fixture (Yumasheva-6 EKB) + 4 regression-теста.
code-reviewer: ✅ APPROVE no critical (regex anchoring verified, decode
safe — no eval/unicode_escape, backward-compat реальный, delisted-house
envelope degrade'ит gracefully, fixture без PII/secrets). Tests: 22 passed.
Closes#566
