Protect today’s journal from deletion in the shared OCaml permissions and mutation layer, remove duplicate localized Cancel actions, and use Enter for newlines / Shift+Enter for new blocks in Code and Calculator on iOS and Android.

Behavior	Before	After
Delete today’s journal	Deletion was allowed	Delete is hidden and direct/stale deletion is rejected; past and future journals remain deletable
Localized destructive dialogs	A translated Cancel could appear beside an extra system Cancel	Exactly one semantic Cancel action for graph deletion, page deletion and sign-out
Code / Calculator keyboard	Enter created a block; Shift+Enter inserted a newline	Enter inserts a newline; Shift+Enter creates one new block and preserves selection/handoff typing

Math and ordinary text keep their existing key behavior. Pending journal deletions are checked against the operation’s recorded local day so replay remains deterministic across midnight.

The iOS dialog fix pins logseq/lui#272. No recordings, logs, release artifacts or signing files are included.

Validation:

• Full OCaml gate: 1186 tests passed. An existing 100ms timing assertion initially failed during parallel compilation, then passed in isolation and in the full rerun without changing its threshold.
• iOS 26 Release checks: English, Chinese, Japanese and French native alerts each show one Cancel and one Delete; Enter/Shift+Enter handoff and UTF-16 selection; Code/Math previews and focus transfer.
• Android: 13 keyboard tests passed; real-core Calculator scenario passed with live 42/126 results, Enter staying in the block, Shift+Enter adding exactly one block, and long-press selection.
• Release simulator and device archive verified app shortcuts, Share Extension and native runtime exports.
