docs: update PLAN.md and BUG_AUDIT.md for v1.0.0 release
...
- Final metrics: 294 tests, 10 TLA+ specs, 32 bugs fixed
- Mark all critical/high/medium/config bugs as resolved
- Document SCRAM-SHA-256, crossmodal.tla, symmetry reduction
- List remaining post-v1.0.0 non-critical tasks

feat: real SCRAM-SHA-256 authentication (Option C)
...
Security:
- New scram.nim module with full SCRAM-SHA-256 per RFC 7677
* PBKDF2-HMAC-SHA-256 key derivation
* HMAC-SHA-256 with multiple overloads for bytes/strings
* Secure nonce/salt generation via /dev/urandom
* Client/server message parsing and proof verification
AuthManager updates:
- registerScramUser(): stores salted credentials (salt + iterations + storedKey + serverKey)
- startScram(): initiates challenge-response handshake
- finishScram(): verifies client proof and returns server signature
- Legacy amSCRAMSHA256 path kept for backward compatibility
HTTP endpoints:
- POST /auth/scram/start — accepts client-first-message, returns server-first
- POST /auth/scram/finish — accepts client-final-message, returns server-final
Tests:
- SCRAM-SHA-256 full handshake test (register → start → compute proof → finish)
- SCRAM-SHA-256 invalid proof rejection test
Build: 0 warnings, all tests pass

feat: clean build + crossmodal.tla + TLA+ symmetry (v1.0.0-prep)
...
Build warnings cleanup (0 warnings):
- Suppress threadpool deprecation warning (baradadb.nim)
- Remove unused 'os' import (logging.nim)
- Fix ImplicitDefaultValue for newNode params (ast.nim)
- Add explicit cstring cast for posix.open (wal.nim)
- Fix HoleEnumConv for MsgKind parsing (server.nim)
TLA+ Formal Verification:
- Add symmetry reduction (Permutations) to all 9 existing specs
- Add SYMMETRY directive to all .cfg files
- New crossmodal.tla: cross-modal consistency spec
* MetadataVectorConsistency, HybridResultValid
* CommittedAtomicity, AbortedAtomicity, TxnStateValid
- New models/crossmodal.cfg
Tests:
- Add Cross-Modal TLA+ Faithfulness tests (4 tests)
Docs:
- Update PLAN.md and BUG_AUDIT.md with completed tasks

- PLAN.md: backup.tla and recovery.tla marked complete, 3 options for tomorrow
- Option A: Clean build (warnings + symmetry reduction)
- Option B: crossmodal.tla
- Option C: True SCRAM-SHA-256
- Cleared 26GB of TLC state files from formal-verification/states/

...
Поправени проблеми:
- MVCC: aborted транзакции вече не стават видими (добавено abortedTxns множество)
- LSM-Tree: поправена загуба на данни при immutable memtable overwrite
- LSM-Tree: поправена SSTable search order (сортиране по id вместо minKey)
- WAL: sync()/close() вече извикват posix.fsync()
