chore: version packages

- Add HTML sanitizer for markdown rendering (XSS prevention)
- Switch service worker to network-first caching (deploys take effect immediately)
- Sanitize Content-Disposition filenames (header injection prevention)
- Expose session.muxName getter, replace unsafe `as any` cast
- Static import for execFile, update CLAUDE.md keyboard shortcuts

 # aicodeman
 
+## 0.5.11
+
+### Patch Changes
+
+- Community contributions and security hardening:
+  - Mobile response viewer: native-scroll panel for reading full Claude responses with markdown rendering via marked.js (PR #62)
+  - PWA support: service worker caching, web app manifest, and Android home screen install (PR #59)
+  - Named Cloudflare tunnel support (PR #58)
+  - Markdown rendering for response viewer with HTML sanitization (XSS prevention) — strips dangerous elements, event handlers, and javascript: URIs
+  - Service worker switched from stale-while-revalidate to network-first caching so deploys take effect immediately
+  - Content-Disposition filename sanitization to prevent header injection in file downloads
+  - Expose session.muxName public getter, replace unsafe `as any` cast in session-routes
+  - Static import for execFile in session-routes
+  - Keyboard shortcut updates: Alt+1-9 tab switching, Shift+Enter newline
+  - Repo restructure for cleaner GitHub landing page
+  - Mobile logo, expandable history, session resume fixes
+
+## 0.5.10
+
+### Patch Changes
+
+- fix: allow bracket characters in model validation regex so models like opus[1m] (1M context window) are accepted instead of silently dropped. Quote the model flag value in tmux spawn commands to prevent bash glob expansion of bracket patterns.
+
+  docs: update macOS launchd instructions to use `launchctl bootstrap` instead of deprecated `load`. Clean up README install and service sections.
+
+## 0.5.9
+
+### Patch Changes
+
+- Mobile keyboard accessory bar: add configurable "Extended Keyboard Bar" setting (Settings > Display > Input) that toggles between simple mode (up/down arrows, /init, /clear, /compact, paste, dismiss) and extended mode (adds left/right arrows, Tab, Shift+Tab, Ctrl+O, Alt+Enter, Esc). Default is simple mode. Setting is device-specific (not synced to server).
+
+  Restyle dismiss button: muted steel-blue tone, fills remaining bar space via flex, larger tap target. Arrow buttons now blue.
+
+  Fix paste overlay visibility on mobile: dialog repositioned to top of screen (15vh from top) so the virtual keyboard doesn't cover it. Textarea enlarged for better usability.
+
+  (Also includes all v0.5.8 changes: case reorder/delete, XSS sanitization, auto-attach PTY on restart, mobile keyboard buttons, macOS installer fixes, terminal flicker fix, state store collision fix.)
+
+## 0.5.8
+
+### Patch Changes
+
+- Case management: add Manage tab with reorder (up/down arrows) and delete for cases; linked cases are unlinked (folder preserved), CASES_DIR cases are permanently deleted. New endpoints: DELETE /api/cases/:name, PUT /api/cases/order. SSE events: case:deleted, case:order-changed.
+
+  Security: sanitize case names from filesystem with /^[a-zA-Z0-9_-]+$/ regex before returning from GET /api/cases to prevent XSS via maliciously-named directories reaching frontend inline onclick handlers.
+
+  Auto-attach PTY: server now calls startInteractive() for recovered tmux sessions during startup so all sessions resume capturing output immediately after deploy, instead of waiting for client selection. Frontend auto-attach condition relaxed from (pid===null && status==='idle') to (pid===null && !\_ended).
+
+  Mobile keyboard accessory: add Shift+Tab, Tab, Esc, Alt+Enter, Left/Right arrow, and Ctrl+O buttons.
+
+  Terminal: fix flicker regression by moving viewport clear inside dimension guard.
+
+  State store: fix temp file collisions on concurrent writes.
+
+  macOS: fix installer failures when piped via curl | bash, add HTML cache support, launchd service template, and trust dialog handling.
+
+  Housekeeping: remove accidentally committed dist/state-store.js build artifact.
+
+## 0.5.7
+
+### Patch Changes
+
+- feat: support "Default (CLI default)" option for model selection. Adds a new empty-value option to the model dropdown that defers to the CLI's own default model instead of forcing a specific model. Ensures empty defaultModel values are treated as undefined when passed to session creation and Ralph loop start, preventing empty strings from being sent as model flags.
+
+## 0.5.6
+
+### Patch Changes
+
+- fix: default new sessions to opus[1m] (1M context window) instead of plain opus (200k context)
+
+## 0.5.5
+
+### Patch Changes
+
+- Add 1M Opus context quick setting — per-case and global toggle that writes `model: "opus[1m]"` to `.claude/settings.local.json` when creating new sessions. Fix mobile layout: banners (respawn, timer, orchestrator) between header and main content now visible by switching from margin-top on `.main` to padding-top on `.app`. Add tablet-optimized respawn banner styles and mobile phone banner refinements.
+
+## 0.5.4
+
+### Patch Changes
+
+- Fix terminal flicker regression — re-add server-side DEC 2026 synchronized output wrapping around batched terminal data. Ink spinner frames (cursor-up + redraw cycles) do not emit their own DEC 2026 markers, so without the server wrapper each partial cursor update rendered individually causing visible flicker. Also: extract SSE stream management, session listener wiring, and respawn event wiring from server.ts into dedicated modules; deduplicate error message extraction across 7 files with shared getErrorMessage() helper; update SSE event count in CLAUDE.md (106 → 117).
+
+## 0.5.3
+
+### Patch Changes
+
+- Readability refactor across 12 core files, extracting ~35 helper methods to reduce duplication:
+  - state-store: extract serializeState(), split assembleStateJson() into focused sub-methods
+  - session: extract \_resetBuffers() (3x dedup), \_clearAllTimers() (10 timer cleanups), \_handleJsonMessage()
+  - ralph-tracker: extract completeAllTodos() (4x dedup), emitValidationWarning(), named similarity constants
+  - subagent-watcher: extract markSubagentAsCompleted(), extractFirstTextContent(), emitToolResult(), findOldestInactiveAgent()
+  - respawn-controller: extract recoveryResetToWatching(), canAutoAccept(), formatRemainingSeconds(), validatePositiveTimeout()
+  - tmux-manager: replace 15 path.includes() with UNSAFE_PATH_CHARS regex, extract buildEnvExports/buildPathExport/\_configureOpenCode helpers
+  - session-auto-ops: extract executeWhenIdle() shared retry helper, convert to options object, add validateThreshold()
+  - app.js: add \_clearTimer() (11 call sites), \_isStaleSelect(), keyboard shortcut lookup table, \_cleanupPreviousSession(), \_resetAllAppState()
+  - route-helpers: add readJsonConfig() (5 inline patterns replaced), validateSessionFilePath() (2 duplicated blocks replaced)
+
+## 0.5.2
+
+### Patch Changes
+
+- Make buffer size limits configurable via CODEMAN\_\* environment variables (MAX_TERMINAL_BUFFER, TRIM_TERMINAL_TO, MAX_TEXT_OUTPUT, TRIM_TEXT_TO, MAX_MESSAGES), falling back to existing defaults. Allows users with fewer sessions or more RAM to tune buffer sizes without patching source.
+
+  Fix duplicate terminal output on tab switch to busy sessions by clearing the terminal before writing the new buffer.
+
+  Fix stale Ink CUP frames after tab switch by sending Ctrl+L to force a clean redraw.
+
+  Fix mobile CJK input handling: resolve textarea positioning, terminal flicker during composition, and layout overflow on small screens. Improve CJK composition lifecycle with better event handling and fallback flush timers.
+
+## 0.5.1
+
+### Patch Changes
+
+- refactor: codebase cleanup — extract route helpers, eliminate boilerplate, optimize hot paths
+  - Add `parseBody()` helper to route-helpers.ts: validates request body against Zod schema with structured 400 error on failure, replacing 37 identical safeParse + error-check blocks across 10 route files
+  - Add `persistAndBroadcastSession()` helper: combines persist + SessionUpdated broadcast into one call, replacing 5 repeated 2-line pairs
+  - Migrate session-routes.ts to use `findSessionOrFail()` consistently (17 inline session lookups replaced) and `parseBody()` (12 patterns)
+  - Migrate ralph-routes.ts to use `findSessionOrFail()` (9 lookups) and `parseBody()` (4 patterns)
+  - Migrate 8 remaining route files to use `parseBody()` (21 patterns total)
+  - Fix O(n log n) eviction in bash-tool-parser.ts: replace `Array.from().sort()[0]` with O(n) min-scan for oldest active tool
+  - Extract `_debouncedCall()` utility in frontend: replaces 4 manual debounce patterns (7 lines each → 1 line) in app.js, panels-ui.js, ralph-panel.js
+  - Net reduction: 208 lines removed across 16 files
+

  *
+ * ## Android IME challenge
+ *
+ * Android virtual keyboards (WeChat, Sogou, Gboard in Chinese mode) use
+ * composition for EVERYTHING — including English prediction and punctuation.
+ * This means compositionstart fires even for English text, and compositionend
+ * may not fire until the user explicitly confirms (space, candidate tap).

+ * We use InputEvent.inputType to distinguish:
+ * - `insertCompositionText`: tentative text, may change (CJK candidates, pinyin)
+ * - `insertText`: final committed text (confirmed word, punctuation, space)
+ *
+ * During composition, `insertText` events are flushed immediately (punctuation,
+ * English words confirmed by IME). `insertCompositionText` waits for
+ * compositionend (CJK candidate selection).
+ *
+ * ## Phantom character for Android backspace
+ *
+ * Android virtual keyboards don't generate key-repeat keydown events for held
+ * keys. When the textarea is empty, backspace produces no `input` event either
+ * (nothing to delete). We keep a zero-width space (U+200B) "phantom" in the
+ * textarea at all times. Backspace deletes the phantom → `input` fires with
+ * `deleteContentBackward` → we send \x7f to PTY and restore the phantom.
