Changes

• Adds coolify-backup-asm/, an initial x86_64 NASM zero-libc skeleton for issue Bare-Metal Backup Daemon in x86_64 Assembly #2.
• Adds a NASM + ld Makefile that builds a static ELF and enforces the 64 KiB binary size limit.
• Implements the _start entry point, direct Linux syscall wrappers, minimal string helpers, fixed ring-buffer metadata, CLI parsing, and a backup --dry-run JSON contract for the first pipeline boundary.
• Adds reserved module files matching the requested future layout for crypto, network, database, and config work.
• Adds a bash test runner covering static ELF output, size limit, direct syscall execution via strace, CLI success/error paths, and objdump capture.

Issues

• Fixes Bare-Metal Backup Daemon in x86_64 Assembly #2

Category

• Bug fix
• Improvement
• New feature
• Adding new one click service
• Fixing or updating existing one click service

Preview

CLI-only low-level daemon skeleton; no UI preview is applicable.

Binary Size Delta

• Previous coolify-backup-asm binary: N/A (new module)
• New binary: 10584 bytes
• Delta against zero/new baseline: +10584 bytes
• Limit: 65536 bytes

Objdump / Disassembly

No existing routines are modified, so there is no disassembly diff against prior assembly code. The test runner captures the current disassembly with:

objdump -drwC ./coolify-backup-asm > ${TMPDIR:-/tmp}/coolify-backup-asm-objdump-main.txt

AI Assistance

• AI was used (please describe below)

If AI was used:

• Tools used: ChatGPT/OpenAI coding agent
• How extensively: Used to inspect the issue, draft the NASM skeleton, run local tests, and prepare this PR; changes were verified locally before submission.

Testing

make -C coolify-backup-asm clean test

Observed locally:

Binary size: 10584 bytes (limit: 65536)
binary size: 10584 bytes
objdump captured: /tmp/coolify-backup-asm-objdump-main.txt
all coolify-backup-asm tests passed

Additional checks included:

file ./coolify-backup-asm
./coolify-backup-asm version
./coolify-backup-asm backup --dry-run
strace -f -e trace=write,exit_group ./coolify-backup-asm version
