[Stivo182]

Что изменено

• Добавлены короткие методы ДиагностикаОшибок:
  • ДанныеОшибки()
  • ЭффективнаяОшибка()
  • КорневаяПричина()
• Реализован потоковый поиск без полной материализации цепочки.
• Сохранено ограничение обхода в 64 физических кадра.
• Учтены внешние и повреждённые кадры, а также усечённые цепочки.
• Исправлена документация о ленивой материализации РазборОшибки.
• Добавлены блоки Возвращаемое значение для методов диагностики.
• Добавлены тесты нового API, граничных условий и ссылочной семантики данных.

Summary by CodeRabbit

• New Features

  • Added error-diagnostics functions for retrieving error data, the first recognized error, the effective error, and the root cause.
  • Added support for safely handling external, unreadable, and truncated error chains.
  • Error-chain parsing is now lazy, with full parsing deferred until required.

• Documentation

  • Expanded guidance and examples for error data, effective errors, root causes, and lazy parsing behavior.

📝 Walkthrough

Walkthrough

The change adds bounded searches for effective errors and root causes, exposes diagnostic functions, expands tests for snapshots and truncation, and documents lazy error-chain parsing.

Changes

Error diagnostics

Layer / File(s)	Summary
Bounded error-chain traversal src/internal/Классы/ОбходчикЦепочкиОшибки.os	Adds searches for the first classified error and the root cause. Both searches handle unreadable chains and the 64-frame limit.
Public diagnostic API and validation src/Модули/ДиагностикаОшибок.os, tests/ТестыДиагностикиОшибок.os	Adds functions for error data, effective-error snapshots, and root-cause snapshots. Tests cover reference behavior, external and damaged envelopes, and 64-frame truncation.
Lazy parsing documentation docs/ДиагностикаОшибок.md, docs/РазборОшибки.md	Documents lazy parsing, return values, reference-preserved data, full-parse limits, and unavailable root causes for truncated chains.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to ea01a

Новые методы диагностики и их тесты покрывают заявленные сценарии, но документация не проходит правило уровней заголовков Markdown. Исправление заголовков требуется для готовности изменения к слиянию.

Use level-3 headings for Возвращаемое значение.

Each #### Возвращаемое значение heading skips from level 2 to level 4. Change these headings to ###, or add an appropriate level-3 parent heading. markdownlint-cli2 reports MD001 for all six locations.

Also applies to: 29-29, 43-43, 56-56, 70-70, 106-106
