// reddb persistent storage core
//
// This module exposes the unified RedDB storage engine for tables, documents,
// graphs, and vectors with a single API surface.

// Low-level primitives (bloom filters, encoding, mmap, serialization)
pub mod primitives;

// Cross-structure index abstraction (trait + bloom segment helper)
pub mod index;

// RedDB Storage Engine (page-based, B-tree indexed)
pub mod engine;

// B+ Tree with MVCC (Concurrent Storage)
pub mod btree;

// Transaction Management (ACID)
pub mod transaction;

// Page Cache (SIEVE Algorithm)
pub mod cache;

// Foreign Data Wrappers (Phase 3.2 PG parity)
pub mod fdw;

// SQLite Import/Compatibility Layer
pub mod import;

// Write-ahead log - serializer is now integrated into storage primitives

// Write-Ahead Log (Durability)
pub mod wal;

// Encryption Layer (Security)
pub mod encryption;

// Remote Storage Backend Abstraction (S3, R2, GCS, Turso, D1)
pub mod backend;

// Keyring integration for secure password storage
pub mod keyring;

// Schema System (Types, Tables, Registry)
pub mod schema;

// Time-Series Storage
pub mod timeseries;

// Queue / Deque Storage
pub mod queue;

// Vector storage stable contract surface (introspection, etc.) — issue #743.
pub mod vector;

// Graph storage stable contract surface (viewport, etc.) — issue #744.
pub mod graph;

// Machine Learning registry + async job queue (ML Sprint 1 — scaffold).
// Feature 5 (classifier), Feature 6 (symbolic regression), and the other
// five ML capabilities all publish models/versions and submit training
// jobs through this module.
pub mod ml;

// Query Engine (Filters, Sorting, Similarity Search)
pub mod query;

// Unified Storage Layer (Tables + Graphs + Vectors)
pub(crate) mod unified;

// Per-collection disk usage accounting for runtime catalog views.
pub(crate) mod disk_accountant;

// Pure tiered storage layout derivation.
pub mod layout;

// Storage/deploy profile selection contract.
pub mod profile;

// Boot-time memory budget resolver (ADR 0073 §1). Resolves the single
// process-wide budget from operator config, the deployment-profile default,
// the cgroup limit, or a conservative fraction of physical RAM. Pool sizing
// and admission enforcement are downstream slices consuming the number.
pub mod memory_budget;

// Embedded single-file `.rdb` artifact skeleton.
pub mod embedded;

pub(crate) mod operational_manifest;

// Blockchain collection kind: pure logic for hash-chained append-only rows.
// Storage/wire integration tracked in issue #521.
pub mod blockchain;

// Signed Writes: ed25519 signer registry + insert verification logic
// for `CREATE COLLECTION ... SIGNED_BY (...)` (issues #520, #522).
// Runtime wiring (insert path, reserved-column injection, REST error
// codes) lands in follow-up slices; this module ships the pure
// primitives the wiring will call into.
pub mod signed_writes;

// Columnar analytics projection (ADR 0069, #1766): the derived, disposable
// columnar representation of an append-only collection. Emitted on the
// checkpoint path, sealed under the crypto page envelope, and read via the
// LSN-pinned analytical scan (columnar segments + un-materialized row tail
// under one pinned snapshot). Runtime wiring into `SegmentManager` checkpoint
// and the query executor lands in follow-up slices.
pub mod columnar_projection;

// Public surface re-used by the rest of the codebase.
