 ## Unreleased
 
+- **Web: same-origin WebSockets accepted, version banner synced to the backend, and token bootstrap race fixed.** The local-mode web server now auto-populates the allowed-origin list (an empty allowlist rejects every `Origin`-bearing request, which previously broke all WebSocket handshakes with a 403). The UI version banner prefers the version the running backend reports (via the config API) over the stale build-time constant, and a transient version-fetch failure no longer permanently disables the backend banner for the session. The initial auth-token bootstrap race that could fail the first request is resolved. `ESC` now reliably terminates only the background tasks spawned by the interrupted turn, and recall context is re-framed so prior-session snippets can't be misread as new instructions.
 - **Deep-audit remediation: security, correctness, and multi-instance robustness.** Permission gate: awk programs that shell out via `print | "cmd"` / `getline` are now classified as mutating AND destructive (previously only `system(`/`>` and only mutating), and `xargs -L N` no longer hides its payload from classification. Glob resolves symlinks before its workspace-boundary check (an in-workspace symlink could previously list outside content); progress-note titles are ANSI-sanitized like every other transcript field. Grep content lines are parsed with unambiguous field separators, so paths like `utf-8-codec.py` are no longer mangled with `-n=false` and sensitive-file attribution is exact. Multi-line edits on CRLF files work again (LF-joined old strings are CRLF-translated when needed). `/import` preserves paths byte-for-byte (only a standalone leading/trailing `--force` is treated as the flag). Post-compaction file reminders include `--add-dir` files. Double-interrupt can no longer orphan the interruption-marker write (unanswered tool_calls). Background web replay falls back to full history (not empty) when the watermark stat fails, and a malformed Agent resume id returns a clean "Agent not found". OAuth: login fails loud when the token response lacks a `refresh_token`; a refresh response without `expires_in` carries the previous lifetime forward instead of refreshing every tick; the device-id file can no longer be read empty mid-creation. A failed `theme="auto"` background probe can be retried by re-selecting auto via `/theme`. Multi-instance: sessions now take a per-session writer lock (a second `pythinker -r <id>`/web worker on the same session is refused instead of interleaving turns), the shared `pythinker.json` index uses a locked read-modify-write (no more lost work-dir registrations), JSONL appenders repair torn final lines after a crash, forks materialize atomically, project-memory mutations abort on read failure instead of wiping the file, the journal is capped at 100 recaps, inbox approve/reject claims candidates atomically, and recall re-arms when another instance writes new memory. Subagents: a failed summary continuation no longer discards a completed agent's work, hallucinated subagent types fail fast with the valid-type list (before any RunAgents child launches), background failures carry an `Agent ID:` + resume hint, and a crash inside the runner's own error handling is logged instead of silently lost.
 - **Breaking (CLI flags): `pythinker web` / `pythinker vis` host short flag is now `-H`.** `-h` is a help alias on both subcommands (matching the root CLI); previously `-h <ip>` bound the host. Scripts using `-h 0.0.0.0` now print help and exit 0 without starting a server — switch to `-H <ip>` or `--host <ip>`. Part of the security/correctness audit (which also confined Grep to the workspace, gated non-HTTPS provider URLs in the web config API to loopback, and stopped saving OpenAI keys on 401/403).
 - **Thinking effort moved to a single top-right label on the input border.** The input box border is now one static frame grey at every effort level instead of recoloring the whole bar cold→hot, and the effort is no longer duplicated in the footer line. It's shown once, as a small label flushed to the right of the input's top border — a level-colored dot (slate→blue→teal→amber→orange→red as `off→max`) plus the muted level word — so the dial stays glanceable without tinting the typing area or cluttering the footer. The label is hidden entirely for native-thinking models (`always_thinking`, no user dial) and non-thinking models, and the rule auto-shortens by the label width so the line never wraps.
