 ## Unreleased
 
+### Sessions
+
+- **`Ctrl+C` interrupts a running turn** — while the agent is working, `Ctrl+C`
+  aborts it on a single press, and the prompt footer now leads with
+  `ctrl+c interrupt` instead of `esc interrupt`. `escape` keeps its existing
+  double-press interrupt. With text in the prompt `Ctrl+C` still clears the
+  draft first, and while a turn is running it can no longer arm the
+  double-press quit from [#51](https://github.com/quickbeard/codev-code/pull/51)
+  — `Ctrl+D`, `<leader>q`, and `/exit` still quit immediately. Configurable as
+  the new `session_interrupt_now` keybind.
+
 ### Sidebar
 
 - **Hidden-sidebar hint shows while busy** — the `ctrl+b N todos` hint from

Docs (en + es `keybinds.mdx`): split the `app_exit` default and added `app_exit_confirm: "ctrl+c"`. See also the `app.tsx`, `dialog.tsx`, and `permission.tsx` rows for their `app.exit.confirm` handlers. | A stray Ctrl+C on an empty/unfocused prompt no longer quits instantly: the first press shows a "Press Ctrl+C again to exit" toast (1.5 s window), the second within that window quits. Ctrl+D, `<leader>q`, and the `/exit` slash commands stay immediate. | Keep our binding split, the `app_exit_confirm`/`app.exit.confirm` definition + mapping, the local confirm commands + gathered bindings, the toast `"secondary"` variant, the test, and the doc defaults; take upstream's surrounding changes. If upstream re-adds `ctrl+c` to `app_exit`, keep it removed. |

+| `packages/tui/src/config/keybind.ts`, `packages/tui/src/component/prompt/index.tsx`, `packages/tui/src/app.tsx`, `packages/web/src/content/docs/keybinds.mdx` (+ `es/`) | Single-press Ctrl+C interrupt. keybind.ts: added `session_interrupt_now: "ctrl+c"` + its `session.interrupt.now` CommandMap entry (`session_interrupt` keeps `escape`; its description gains "(press twice)"). prompt/index.tsx: added the `session.interrupt.now` command — same guards as upstream's `session.interrupt` but it aborts on the first press, and its `enabled` requires a busy session AND an empty prompt so ctrl+c falls through to `prompt.clear` (draft present) or `app.exit.confirm` (idle) instead of racing them on layer order; gathered the command in the `prompt.palette` binding list; the busy footer hint reads `interruptShortcut()` (resolves `session.interrupt.now`, falling back to the escape label when unbound) instead of the hardcoded `esc`, and still shows the escape label while its double-press is armed. app.tsx: split `app_exit_confirm` out of the shared exit `useBindings` into its own layer whose `enabled` also requires `sync.data.session_status[route.data.sessionID]` to be idle, so ctrl+c can't arm the quit confirm mid-turn (`app_exit` keeps the shared predicate). Docs (en + es): added the `session_interrupt_now` default. Covered by the fork-only `packages/tui/test/interrupt.view.test.tsx`. See also the double-Ctrl+C row above, whose scope this narrows. | `esc` alone was a two-press, low-discoverability interrupt; Ctrl+C is what users reach for to stop a running agent, and it now leads the busy footer. Gating on `enabled` rather than binding order keeps the ctrl+c precedence (clear draft → interrupt → exit confirm) deterministic, since same-priority layers resolve by registration order and `useBindings` re-registers on every reactive change. | Keep the `session_interrupt_now` definition + mapping, the `session.interrupt.now` command and its `enabled` predicate, the footer shortcut memos, the split exit layer, the doc lines, and the test; take upstream's surrounding changes. If upstream binds `ctrl+c` to something else in the prompt, re-audit the precedence chain end to end. |
 | `packages/opencode/src/installation/index.ts` | Updater detects/queries/installs `codev-code` (npm-family); GitHub fallback → quickbeard/codev-code. `method()` drops upstream's `~/.local/bin` → `curl` check, keeping only `~/.opencode/bin`. The `curl` upgrade branch refuses instead of running upstream's install script: `upgradeCurl` + `upgradeScriptShell` + the `Stream` import are removed, and `case "curl"` returns `UpgradeFailedError` pointing at `npm i -g codev-code` | `codev-code upgrade` and the update notification target OUR npm package, never stock opencode. brew/choco/scoop probes never match (no such packages). A `curl`-detected binary (in `~/.opencode/bin`) is a stock opencode install; piping upstream's `opencode.ai/install` script would silently replace the fork with stock opencode. `~/.local/bin` is dropped because it's also a common npm/bun global-bin prefix, so a legitimate package-manager install there was misdetected as curl (now falls through to the manager probes). | Keep our package names, the `~/.local/bin` removal, and the curl refusal; keep `upgradeCurl`/`upgradeScriptShell`/`Stream` deleted (take upstream's changes elsewhere). |
 | `packages/opencode/src/cli/cmd/uninstall.ts` | npm-family uninstall commands (display + exec maps) `opencode-ai` → `codev-code` | `codev uninstall` must remove the fork's actual npm package; the old name was a silent no-op for every npm-installed fork user. NOT renamed: brew/choco/scoop package names (`opencode` — the fork publishes no such formula/package, and `method()` never resolves to those for a fork install) and the curl `.opencode/bin` + `# opencode` shell markers (they match upstream install-script artifacts, not the fork's). | Keep our `codev-code` names; take upstream's surrounding changes. |
 | `packages/opencode/src/config/config.ts` | `share` defaults to `"disabled"` when unset | Sharing publishes sessions to upstream's share service; internal users must opt in via config. | Keep our default block. |
