…ture, multi-distro install, screenshot placeholders - Replace all prose en/em dashes with colons across all doc files - Remove emojis from navbar, sidebar, and homepage - Add circular profile photos for both team members on homepage - Restructure README.md with HTML collapsible TOC, team table, multi-distro install steps - Add Debian/Ubuntu/Kali and Arch Linux install steps in environment-setup.md - Add screenshot placeholders to 5 doc pages (environment-setup, phase1, phase2, phase3, compliance) - Create docs/static/img/screenshots/ with minimal placeholder PNGs so build resolves refs - Expand all 7 doc pages to be detailed and professional (no AI feel, no emojis) - Build verified: 0 errors
Covers Docusaurus build artifacts, xv6 build outputs (kernel binary, fs.img, object files, debug symbols, usys.S), QEMU/GDB session files, editor/OS junk files, and LaTeX intermediates.

…console spam printf calls write() which is itself a syscall, so logging every ECALL via printf produces one TRAP line per character printed. Remove the printf and the now-unused scause_name() helper entirely. Audit coverage is provided by audit_log() calls in the syscall handlers, readable via the audit_dump userspace tool. Update phase3-audit-log.md to reflect the correct design.
Replace the four-word djb2-style teaching hash with a full SHA-256 implementation. The interface (pw_hash) is unchanged — all call sites adapt automatically via HASH_LEN. Key changes: - HASH_LEN 32 → 64 (SHA-256 = 64 hex chars = 256 bits) - PASSWD_BUF_SIZE 1024 → 2048 (room for 16 users with 64-char hashes) - pw_hash() now computes a standard SHA-256 digest (~80 lines, no deps) - Documentation and report updated to reflect SHA-256 usage
… files - kernel security modules: explain SHA-256, credential parsing, audit ring buffer, DAC resolution - kernel integration: syscall dispatch with audit hook, permission checks in open/exec/read/write - process management: security field init, fork inheritance, auth seed flow - user programs: login flow, compliance test matrix, syscall name decoding - docs site: landing page data flow, PDF builder two-pass rendering, print stylesheet
Removed the text compliance report from README and added a compliance test results image.
auth.c: pw_hash hex loop used an unsigned loop counter, so `j >= 0` never became false and the digest write ran off the buffer into unmapped memory, panicking at boot. Use a signed counter. Also move the 2KB read_passwd/write_passwd buffers to static storage so the auth_login -> read_passwd chain no longer overflows the 1-page kernel stack (struct credential grew with the SHA-256 digest). compliance_test.c: restore the pass_count/fail_count declarations and the T17/T18 statements that were dropped, which left the file unable to compile. usertests.c: drop the unused fsblocks variable that broke the build under -Werror.
