06. Rewire keybinds — h/l drill+pop, digits switch tabs, focus starts on current

meta: id: yazi-remake-06 feature: yazi-remake priority: P1 depends_on: [yazi-remake-01, yazi-remake-05] tags: [implementation, keybinds, tests-required]

objective:

• Rewire the Shell dispatch so the sidebar's special-cased j/k branch is gone, h/l drill/pop on depth-tabs and swipe on fixed tabs, digit keys + [ ] are the sole tab switcher, and app focus starts on the current pane.

deliverables:

• src/components/Shell.tsx (dispatch) — SIDEBAR_ACTIONS set + the if (nav.activePane() === SIDEBAR_PANE) branch deleted
• h/l unified: depth-tabs l=current-drills (open emit), h=current-pops (noop at depth 0); fixed-pane tabs h/l=swipe(∓1, count)
• 1-6 / tab-goto-*, tab-next/tab-prev ([/]) — the only tab switchers
• Initial focus + tab-enter land on DEPTH_CENTER_PANE
• keybinds.jsonc reviewed (update labels/help only if needed)

steps:

• Read the current dispatch() (post task 01 it references a deleted SIDEBAR_PANE — fix the compile here)
• Remove the SIDEBAR_ACTIONS constant and its branch
• In the default case, implement: digit/tab-goto → setActiveTab; swipe-prev → (depth-tab & current & depth>0) popDepth else (depth-tab & current & depth==0) noop else swipe(-1, count); swipe-next → (depth-tab & current) emit open else swipe(1, count)
• Move/list actions (move-down/up, jump-*, page-*, goto-top/bottom) flow to PAGE_ACTIONS → emit("nav.action") for the current pane only
• Confirm escape/command/visual-mode/toggle-select/audio/global branches unchanged
• Verify the app boot path sets focus to current (task 01 set the signal; confirm dispatch doesn't override)
• Run diagnostics + harness key sequence

tests:

• Unit: dispatch("move-down") on a depth-tab current pane emits nav.action {action:"move-down"} (Arrange current pane, Act, Assert emit)
• Integration: dispatch("swipe-next") on a depth-tab at depth 0 emits open (drill); dispatch("swipe-prev") at depth 1 pops to depth 0; at depth 0 swipe-prev is a noop
• e2e (harness): l drills (depth 0→1, parent populates), h pops (1→0, parent blanks), 1/2/3 switch tabs, j/k move the current list cursor without changing depth

acceptance_criteria:

• No SIDEBAR_PANE or SIDEBAR_ACTIONS references in Shell.tsx
• h at depth 0 is a noop (does not error, does not change pane)
• l at current on a depth-tab drills (depth+1)
• Digit keys switch tabs; focus lands on current pane
• j/k move within current only

validation:

• grep -n "SIDEBAR" src/components/Shell.tsx returns nothing
• lens_diagnostics paths=[src/components/Shell.tsx] severity=error → 0 findings
• Harness: init (focus on current) → l (depth 1, parent filled) → l (depth 2) → h (depth 1) → h (depth 0, parent blank) → 3 (Discover tab, focus on current) → j/k move

notes:

• Depends on 01 (pane model: swipe bounds, no SIDEBAR) and 05 (dispatch lives in the rebuilt Shell)
• If keybinds.jsonc has a tab-next/tab-prev mapping conflict, resolve here
• The noop h at depth 0 should feel inert (yazi: at root, h does nothing)
