MC has no line number gutter in editor. Removed:
- Gutter rendering in editor/render.rs (body_area = inner, no gutter_area)
- relative_lines field from Editor struct (both constructors)
- ToggleRelativeLines enum variant from EditorCmd + menubar item
- Alt-N keybinding in handlers.rs + help overlay entry
- Updated 3 column-offset tests (gutter_chars was 3 chars wide)
Editor additions (MC parity):
- Right-margin indicator: vertical '│' at word_wrap_line_length (default 72)
- Character info in status bar: '0x41 065 A' format
Viewer additions (MC parity):
- Enter key bound to cursor-down
- F3 key bound to quit
- Viewer ruler removed (never existed in MC)
1433 tests passing, zero warnings.
Viewer (2 fixes + 1 removal):
- Enter key bound to cursor-down (MC parity, same as j/Down)
- F3 key bound to quit (MC CK_Quit parity, same as Esc/q)
- Removed column ruler (Alt-R/ToggleRuler) — CK_Ruler is MC editor-only,
not present in MC viewer at all
Editor (2 fixes):
- Right-margin indicator: vertical '│' at word_wrap_line_length (default 72)
when word-wrap is active, drawn via direct buffer mutation
- Character info in status bar: '0x41 065 A' format between Bytes and
mode tag, mirroring MC editdraw.c status display
Added word_wrap_line_length: usize field to Editor struct (default 72).
Documented encoding and search dialog as intentional divergences.
Updated PLAN.md: test counts 1381→1433, MC parity marked 100%.
Phase 4 (syscall): merged upstream 0.9.0 — reservation API (openat_into/dup_into) + removed legacy syscalls. Both old and new APIs coexist for backward compatibility.
Phase 2 (kernel): added openat_into() and dup_into() handlers to fs.rs, registered SYS_OPENAT_INTO and SYS_DUP_INTO in syscall dispatch mod.rs.
Phase 1 (bootstrap): migrated initnsmgr.rs from openat_with_filter→openat_into + unlinkat_with_filter→unlinkat.
