From 547262c395df3c3c16d530c7ca60a9d39162f39e Mon Sep 17 00:00:00 2001 From: Markus Maiwald Date: Fri, 2 Jan 2026 14:12:00 +0100 Subject: [PATCH] Phase 27-29: Visual Cortex, Pledge, and The Hive MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PHASE 27: THE GLYPH & THE GHOST (Visual Cortex Polish) ======================================================== - Replaced placeholder block font with full IBM VGA 8x16 bitmap (CP437) - Implemented CRT scanline renderer for authentic terminal aesthetics - Set Sovereign Blue background (0xFF401010) with Phosphor Amber text - Added ANSI escape code stripper for clean graphical output - Updated QEMU hints to include -device virtio-gpu-device Files: - core/rumpk/libs/membrane/term.nim: Scanline renderer + ANSI stripper - core/rumpk/libs/membrane/term_font.nim: Full VGA bitmap data - src/nexus/forge.nim: QEMU device flag - docs/dev/PHASE_26_VISUAL_CORTEX.md: Architecture documentation PHASE 28: THE PLEDGE (Computable Trust) ======================================== - Implemented OpenBSD-style capability system for least-privilege execution - Added promises bitmask to FiberObject for per-fiber capability tracking - Created SYS_PLEDGE syscall (one-way capability ratchet) - Enforced capability checks on all file operations (RPATH/WPATH) - Extended SysTable with fn_pledge (120→128 bytes) Capabilities: - PLEDGE_STDIO (0x0001): Console I/O - PLEDGE_RPATH (0x0002): Read Filesystem - PLEDGE_WPATH (0x0004): Write Filesystem - PLEDGE_INET (0x0008): Network Access - PLEDGE_EXEC (0x0010): Execute/Spawn - PLEDGE_ALL (0xFFFF...): Root (default) Files: - core/rumpk/core/fiber.nim: Added promises field - core/rumpk/core/ion.nim: Capability constants + SysTable extension - core/rumpk/core/kernel.nim: k_pledge + enforcement checks - core/rumpk/libs/membrane/ion_client.nim: Userland ABI sync - core/rumpk/libs/membrane/libc.nim: pledge() wrapper - docs/dev/PHASE_28_THE_PLEDGE.md: Security model documentation PHASE 29: THE HIVE (Userland Concurrency) ========================================== - Implemented dynamic fiber spawning for isolated worker execution - Created worker pool (8 concurrent fibers, 8KB stacks each) - Added SYS_SPAWN (0x500) and SYS_JOIN (0x501) syscalls - Generic worker trampoline for automatic cleanup on exit - Workers inherit parent memory but have independent pledge contexts Worker Model: - spawn(entry, arg): Create isolated worker fiber - join(fid): Wait for worker completion - Workers start with PLEDGE_ALL, can voluntarily restrict - Violations terminate worker, not parent shell Files: - core/rumpk/core/fiber.nim: user_entry/user_arg fields - core/rumpk/core/kernel.nim: Worker pool + spawn/join implementation - core/rumpk/libs/membrane/libc.nim: spawn()/join() wrappers - docs/dev/PHASE_29_THE_HIVE.md: Concurrency architecture STRATEGIC IMPACT ================ The Nexus now has a complete Zero-Trust security model: 1. Visual identity (CRT aesthetics) 2. Capability-based security (pledge) 3. Isolated concurrent execution (spawn/join) This enables hosting untrusted code without kernel compromise, forming the foundation of the Cryptobox architecture (STC-2).
