// NODE.000 / ROOT / OPERATIONAL

ROCEN // A Minimal Workspace Capture Engine.

Defeat visual fatigue. A high-utility productivity framework built on a strict zero-collection manifest. Engineered by Darshserphic on the Flutter + Hive + Riverpod runtime tree.

QuickNote Workspace Sandbox

A boundless, anti-collapse text scroll viewport. Explicit Expanded boundaries + SingleChildScrollView parameters force input metrics to scale dynamically with the system keyboard.

Instantaneous high-contrast theme toggling mapped to a local caching registry (Hive `system_settings` box) for zero-lag rendering.

Cryptographic Stack

Notes are sealed on-device before they ever touch a Hive block. The key never leaves RAM; the ciphertext never leaves the sandbox unencrypted.

On-Device Screen Registry

Raw device capture frames — no mockups, no filters. Pure monochrome output from the compiled Flutter runtime. Each frame documents a live module surface.

Air-Gapped Security Protocols

// PIPE.01 / STORAGE ENGINEACTIVE

Storage Pipeline (Hive NoSQL)

Rocen bypasses heavy SQL frameworks. It uses Hive — a lightweight NoSQL key-value engine. Data writes directly to flat binary blocks on internal device hardware. No cloud sync, no servers, no telemetry.

> engine.id .......... HIVE

> engine.type ........ NOSQL / KEY-VALUE

> storage.format .... FLAT.BINARY.BLOCK

> target ............ INTERNAL.HARDWARE

> complexity ........ O(1) READ

// PIPE.02 / RAM FIRSTACTIVE

Memory-First Pipeline

Boxes buffer entirely inside active RAM on boot. Reads execute with absolute zero disk delay. Writes update the memory registry instantly, then lazily flush to physical binary partitions.

BOOT → RAM.HYDRATE

READ → 0ms.DISK

WRITE → FLAT.BLOCK

// PIPE.03 / ZERO COLLECTACTIVE

Absolute Zero Collection

No telemetry, analytics tokens, crash transmitters, or third-party scrapers. User data never leaves the hardware.

Root Engine Documentation

IDX

PHASE

DIRECTIVE

Root Engine

Initializes state tracking via Riverpod and local disk storage via Hive with active corruption bypass.

Gateway Layer

Intercepts load phases with a sequential 2-second opacity mapping (Fade-In → Hold → Fade-Out).

Hub Navigation

Minimal typography track enforcing absolute scaffold layouts so keyboards slide as overlays.

Matrix Timeline

13-column structural array of all 365 calendar segments.

QuickNote Sandbox

Anti-collapse scroll viewport with explicit Expanded boundaries.

Interface Regulation

Right-to-left full-width sliding panels at 1.0 width factor.
