+# Stable publication has exactly one GitHub environment gate. Push the CLI,

+# Changelog
+
+All notable changes to the Go line (Reasonix 1.0+) are recorded here. The legacy
+`0.x` TypeScript history lives on the [`v1`](https://github.com/esengine/DeepSeek-Reasonix/tree/v1)
+branch.
+
+## Unreleased
+
+### Fixed
+
+- **v1.24.2 session snapshot & recovery root fix:** Keep PR #7982's WAL/CAS/lease
+  safety foundation, but replace process-level "I hold a lease" ownership with a
+  generation-bound `SessionWriteAuthority`. Same-revision tool-preview/load
+  reshapes no longer false-diverge; recovery files are bounded to one path per
+  writer/lineage; empty checkpoints heal from their own WAL; projection lineage
+  rebinds across upgrade/model switch and inherits across recovery forks without
+  changing provider-visible prompt bytes. Catalog upgrades to disposable
+  `session-catalog/v3.sqlite` with recovery lineage roles
+  (`normal|covered_copy|adopted|diverged`); covered idle copies move to the
+  recoverable `.trash` using a 15-minute idle threshold applied on two early
+  sweeps (at startup and ~20 minutes later), then a 24-hour threshold on the
+  6-hour background ticker; independent diverged branches stay and are listed
+  for user choice. v1/v2 catalogs are
+  left byte-unchanged for coexistence/downgrade.
+  **v1.24.1** only hid/reclaimed already-created covered copies and fixed Windows
+  flash-window startup; **v1.24.2** stops the misclassification source and repairs
+  existing user directories without rewriting authoritative JSONL/WAL/sidecar data.
+
+- Goal now runs continuously by default: the former 16-round per-Run boundary,
+  10/20/40 cross-Run quotas, default wall-clock budget, and numeric
+  no-progress/Todo-stall pauses no longer stop valid work. Progress guards still
+  detect repeated host outcomes and zero-evidence work, but redirect the model
+  to re-plan instead of producing `goal_run_budget` or `goal_stuck`. Explicit
+  `[agent].goal_token_budget`, `--max-steps`, positive time/cost budgets, manual
+  pause/stop, genuine user/external blockers, and evaluator fail-closed behavior
+  remain available. The Goal token budget defaults to `0` (off); resuming its
+  `budget_spend` pause grants a fresh slice without clearing cumulative usage.
+  Goal status reports turns, provider requests, tokens, the optional configured
+  token threshold, and cumulative active work time. Bot `max_steps` also
+  defaults to `0` (continuous), while positive user configuration is enforced.
+
+- Removed numeric Goal pauses in existing sidecars automatically normalize to
+  `running` without sending a model request. Active Goal sidecars write
+  `turnsLimit: -1` as a downgrade-safe unlimited sentinel while public runtime
+  APIs retain deprecated limit fields as `0`. The migration preserves unknown
+  fields, todos, checkpoints, usage, evidence, and historical metadata.
+
+- Goal is now the sole long-task runtime. Historical AutoResearch sidecars
+  migrate transactionally into Goals with research compatibility metadata. Invalid archives block
+  fail closed and remain read-only, retaining the task id and compatibility mode
+  for a restart or `/goal resume` retry; successful Goal-only sidecars omit the
+  old task id and write an explicit downgrade fence so previous readers cannot
+  reactivate the removed runtime.
+
+- Context-dependent workflow tools now share one host-side execution boundary.
+  Goal, Plan sign-off, and background-job calls cannot reach permissions,
+  hooks, leases, or Execute outside their owning context; mixed batches execute
+  valid calls once and stop safely after one repair. Child agents also isolate
+  inherited Goal, Jobs, and live memory queues, while persisted tool identity
+  records the effective child schema projection.
+
+- **Issue #7575:** Linux Bash under bubblewrap no longer mounts a fresh empty
+  `--tmpfs /tmp` on every call. Consecutive commands in the same logical session
+  now share a private temporary directory (bound at `/tmp` on Linux, exported via
+  `TMPDIR`/`TMP`/`TEMP` on all platforms) without exposing the host public
+  temporary root. `/new`, `/clear`, resume of another session, and branch
+  switches rotate the directory; model/settings hot rebuilds keep it. Sub-agent
+  runs get independent directories. Temporary files are not durable across process
+  restarts.
+
+### Added
+
+- Added `[ui].show_turn_usage` so CLI/TUI users can hide per-request token and
+  cost receipts from transcript scrollback without disabling usage accounting.
+
+## [1.20.0] — 2026-08-05
+
+Extension kernel, Task Monitor, and safer Goal completion.
+
+Compact decision surfaces, local decision receipts, unified extension kernel,
+native Task Monitor, bounded sub-agent progress, Goal fail-closed completion,
+MiMo and DashScope Responses fixes, SSH remote access simplification, and
+multiple Desktop stability improvements.
+
+### Highlights
+
+- **Unified Extension Kernel and Extension Protocol v1**: Immutable runtime
+  snapshots, fail-atomic reload, Plugin Manifest v1 (prompts, themes, full-trust
+  code runtimes), stable JSON-RPC sidecar protocol, interceptor dispatch,
+  streaming provider adapter, structured UI, and Go SDK.
+- **Native Task Monitor**: Monitor agent tasks natively in CLI and Desktop with
+  lifecycle semantics and session-scoped summary view.
+- **Bounded Sub-agent Progress Forwarding**: Forward structured progress for
+  `task`, `parallel_tasks`, and `fleet` without flooding the parent stream.
+  Renders nested lifecycle cards in Desktop and stable per-child transcript
+  slots in CLI.
+- **Goal Completion Fail-Closed**: Replace free-form Goal footer markers with a
+  stable `update_goal` tool and epoch-scoped per-turn reports. Centralized
+  completion logic with bounded evaluator, progress-aware budgets, and
+  pause/resume controls.
+- **Ablation Subsystem Switches**: Switch subsystems off behind one shared
+  vocabulary for controlled experiments. Includes planner, subagent, retrieval,
+  evidence, and compaction.
+- **Benchmark Cost per Solved Task**: Report cost per solved task, tokens per
+  solved, median wall time, and failure-class breakdown in e2e reports.
+- **Compact Decision Surfaces and Local Receipts**: Compact footer decision-card
+  layout with bounded scroll, dense action rows, and overflow disclosure.
+  Record bounded Ask, approval, and recovery decisions as local transcript
+  receipts.
+- **Simplified SSH Remote Access**: Remove Remote Workbench protocol and
+  stacks; reuse CLI/Serve remote model. Desktop opens per-host native web child
+  windows via SSH. Keyless remote Serve setup with loopback-only page.
+- **Model Usage Charts with Primer Palette**: Replace monochrome accent ramp
+  with GitHub Primer data-viz two-set categorical palette. Fix donut overflow
+  on hover and keyboard accessibility.
+- **Cross-platform Extension and Task Monitor Reliability**: Make
+  content-reference eviction deterministic, reject Unix and Windows absolute
+  plugin paths consistently, stabilize parallel-task cancellation, and restore
+  reliable Windows validation for Task Monitor and remote provider setup.
+- **MiMo and DashScope Responses Wire Alignment**: Fix multi-turn tool loops,
+  reasoning round-trip, JSON output for MiMo; fix DashScope second-turn 400
+  error, all-zero usage suppression, and vendor-aware cache TTL.
+- **Desktop Stability Fixes**: Recover stuck updates and legacy WebKit, contain
+  macOS alias repair startup crashes, keep composer overflow stacks readable,
+  and harden account verification and community flows.
+- **Remote Web Recovery After SSH Drops**: Add integration regression test for
+  SSH drop, forward recovery, and window reload. Document transient outage
+  behavior.
+- **CI: Auto-minimize Activity-Farming Spam Comments**: Detect and minimize
+  template spam comments from non-contributor accounts based on structural
+  signals.
+
+### Added
+
+- Added Extension Protocol v1 and the unified extension kernel: installed or
+  linked sidecars can contribute tools, skills, commands, hooks, MCP servers,
+  providers, interceptors, and structured UI surfaces through a versioned
+  NDJSON contract and the public Go SDK. CLI, Desktop, ACP, and Serve support
+  fail-atomic runtime reloads; Serve also renders extension surfaces and lists
+  extension-hosted providers without exposing credentials.
+- Added the structured Goal completion protocol: the always-registered
+  `update_goal` tool (continue/complete/blocked with reason and next_action)
+  replaces the `[goal:*]` footer markers. The Goal FSM is now the exclusive
+  cross-turn decision point and validates every complete claim against Delivery
+  readiness; when the model submits no report, an independent bounded evaluator
+  (recovery_model → guardian_model → main model, no tools/history, usage
+  attributed to `goal-evaluator`) judges the turn once, and any evaluator
+  failure pauses the goal instead of continuing silently.
+- Added Goal budget classes with safe pauses: simple 10 turns / 200k tokens,
+  write 20 turns / 400k tokens, AutoResearch 40 turns / 800k tokens, and a
+  4-turn no-host-verifiable-progress gate. Pauses keep all Goal state; `/goal
+  resume` continues and adds one slice of the current class when the pause was
+  budget-related. `/goal status` shows the full turn/token/no-progress runtime,
+  and `/goal pause` manually suspends a running Goal.
+- Added the `goalRuntime` nested view to the desktop Meta, the remote protocol
+  (`session/goal/pause` operation, `goalRuntime` DTO on session meta), and the
+  ACP status payload; the desktop Composer goal menu shows the runtime summary
+  with distinct pause/end/resume actions.
+
+### Changed
+
+- Delivery no longer retries final-answer readiness with hidden model messages:
+  a plain Delivery run ends on the first unsatisfied final answer and surfaces
+  the recovery card, while a Goal + Delivery run has the Goal FSM absorb the
+  failure and continue under budget with the missing requirements as the next
+  turn's prompt. Historical `[goal:*]` footers are stripped from old transcripts
+  for display only and never participate in state decisions.
+- Added a **Remote SSH** module (VS Code Remote-SSH style): a user-global
+  `[remote]` host config, `reasonix remote` CLI (add/list/remove/import/test/
+  connect/status/forward/serve/fs) and `/remote` slash command, an SSH transport
+  with trust-on-first-use host-key verification, keepalive + exponential-backoff
+  reconnect, `-L`/`-R` port forwarding, and SFTP file access. `connect`
+  bootstraps a persistent `reasonix serve` on the remote host and tunnels its
+  loopback port so the full agent runs remotely. The desktop app adds a
+  **Settings -> Remote SSH** host manager, a remote file browser/editor, a
+  port-forwarding panel, and a status-bar connection chip. Linux/macOS remotes.
+- Added `reasonix serve --port-file/--token-file/--pid-file` so a supervised
+  headless serve can bind an ephemeral port and read its auth token from a file
+  (keeping it out of `ps`).
+- Added an authenticated, loopback-only Provider setup page for `reasonix
+  serve`. A Serve whose selected Provider is missing its API key now remains
+  reachable, stores the submitted key in that host's Reasonix credential file,
+  and rebuilds the active controller in place without restarting Serve.
+- Added Claude Code-style searchable CLI pickers for models, providers, and
+  sessions, with arrow, Vim, and `Ctrl+P` / `Ctrl+N` navigation.
+- Added `-p` / `--print`, `text`, `json`, and `stream-json` output modes for
+  one-shot use and automation.
+- Added session-scoped `--allowed-tools`, repeatable `--add-dir`, Claude-compatible
+  permission modes, flexible `--resume [QUERY]`, and the `--copy` resume escape
+  hatch.
+- Added `/status` details for the active model, effort, cache, Git state,
+  background jobs, work profile, and provider balance where available.
+- Remote SSH workspaces now open as a standalone remote web window again.
+  Opening a workspace from the status bar or the Remote Server tab starts or
+  reuses the remote `reasonix serve`, tunnels its loopback port, and opens the
+  Serve web client in a dedicated per-host window. The remote web page uses
+  the provider configuration and API keys on the **remote** host; the desktop
+  no longer exposes its local providers to remote hosts. If the selected remote
+  Provider is missing its API key, the window opens a setup page that saves the
+  key only on that host and then opens the normal Serve UI. The Remote Workbench
+  protocol, its Provider Broker, and the same-window remote projection were
+  removed. Legacy mirror and provider-trust files are not deleted
+  automatically; Settings -> Remote SSH shows a cleanup card when they exist.
+  The hidden `remote attach-workspace`, `remote runtime-workbench`, and
+  `remote workbench-build-id` commands now fail with a pointer to
+  `reasonix remote connect <host> --open`.
+- Automatic Plan Mode has been retired. Plan Mode is now always entered through
+  an explicit user choice, and the one-time config v5 upgrade removes legacy
+  `agent.auto_plan` and `agent.auto_plan_classifier` values so upgraded users
+  receive the same behavior as new users.
+- `Shift+Tab` now cycles CLI safe modes from Ask to Auto to Plan, while YOLO
+  remains an independent `Ctrl+Y` toggle.
+- Model, provider, resume, and approval menus now use consistent row selection;
+  slash completion, help, aliases, and dispatch share one command registry.
+- The full-screen CLI composer now uses theme-accented borders and a slim bar
+  cursor by default, grows within the available terminal height, scrolls long
+  drafts independently, and preserves selections across explicit image paste.
+- The persistent CLI footer now uses a responsive, theme-aware layout for
+  interaction state, model, effort, localized work mode, Git identity, cache,
+  context, compaction headroom, jobs, and balance. Narrow terminals move or
+  compact complete groups instead of clipping labels.
+- CLI clipboard actions now separate terminal-native text paste from explicit
+  image paste: `Ctrl+V` on macOS/Linux, `Alt+V` on Windows, or `/paste-image`.
+  Local transcript copy verifies the native clipboard write, while SSH uses a
+  clearly labelled OSC 52 fallback.
+- Runtime rebuilds after model, effort, or work-mode changes now preserve the
+  conversation, session permission overrides, additional directories, and
+  session lease ownership.
+- Agent execution now monitors host-observed Todo progress automatically. A
+  stalled current item receives a recovery nudge after 8 tool-call rounds with
+  no new completion, unique read, command, or mutation, and pauses with saved
+  work after 16. Exact repeats do not renew the progress lease; real work does.
+  Two-level task lists keep the single in_progress contract: the active
+  sub-step is the only current item while its phase stays pending, and the
+  phase becomes in_progress to sign off only after all of its sub-steps are
+  completed. A level-1 sub-step with no phase header above it is rejected.
+  Executor and planner rounds now use automatic progress management. Retired
+  `[agent].max_steps` and `planner_max_steps` keys remain parseable for upgrades,
+  but are ignored and removed by a one-time migration so stale hidden limits
+  cannot truncate new behavior. One-off CLI and unattended bot limits remain.
+
+### Fixed
+
+- Fixed long parallel sub-agent research being silently lost when combined
+  `parallel_tasks` or `fleet` answers exceeded the single-tool output limit.
+  Persisted sessions now keep each child transcript independently, return a
+  bounded fair preview plus stable reference for every result, and page full
+  answers through the conversation-scoped `read_subagent_result` tool.
+- Fixed Remote Workbench failing with only `initialize: workbench-desktop:
+  connection closed` on fresh or cross-platform SSH hosts. Desktop now proves
+  the exact Host CLI Build ID, provisions the matching verified release without
+  requiring remote npm, runs the managed binary explicitly, and preserves a
+  safe structured bootstrap error when the remote command exits early.
+- Hardened Bash permission reuse for dynamic and indirect execution. Parameter/arithmetic expansions,
+  assignments, redirects, heredocs, and globs can only be remembered as exact
+  `Bash=<literal>` rules, while still using Auto's normal fallback. Nested or
+  indirect execution now requires a human in interactive Ask/Auto and fails
+  closed in headless Ask/Auto/DontAsk. Broad Bash rules, Guardian/hook allows,
+  and the approved-plan window can no longer silently authorize that stricter
+  class; YOLO remains the explicit full-access bypass and sandbox enforcement
+  is unchanged.
+- Fixed Desktop sessions incorrectly locking themselves during Goal + Delivery
+  mode changes, controller rebuilds, duplicate-tab restore, and background
+  reattachment. Desktop now keeps one process-local runtime owner per canonical
+  session, fences stale controller events by runtime epoch, blocks sends until
+  that runtime is ready, and scopes single-instance ownership to
+  `REASONIX_HOME` instead of the executable path. Switching saved sessions is
+  now transactional: a target build, restore, or lease failure leaves the
+  current controller, lease, path, mode profile, and runtime epoch untouched.
+- Stabilized the desktop rich composer caret after skill and plugin invocation
+  tags. DOM→model and model→DOM selection mapping now treat invocation chips as
+  zero-length atoms while still counting user text that lands inside the NBSP
+  caret anchor (common on Windows WebView2), restore both selection ends, and
+  recover the insertion point from a `beforeinput` snapshot when the browser
+  temporarily loses selection — so mid-text edits no longer jump to the end.
+- Isolated the Windows desktop WebView2 shell from stale system proxies, so an
+  exited proxy client cannot leave the embedded UI hidden during startup. If
+  WebView2 still does not reach DOM-ready within 15 seconds, Reasonix now shows
+  the native window with a recovery prompt instead of appearing not to launch.
+  Remote Markdown images are fetched by the backend with Reasonix's proxy
+  configuration instead of bypassing that proxy through the isolated WebView.
+- Restored captured-mouse right-click text paste, made composer drag selection
+  copy through the verified native clipboard path, and kept non-Git footer
+  telemetry left-aligned without reserving an empty data band.
+- Restored stateful MCP behavior after the v1.17.13 regression: user-added
+  servers work without extra trust settings (including delivery-mode on-demand
+  calls), repository-provided servers use one exact launch confirmation, and
+  stdio tools reuse one persistent process so browser sessions survive across
+  calls without repeated startup latency. The former trust/reverify/catalog
+  management UI and CLI are removed.
+- Localized persistent-footer labels and displayed work-mode values in English,
+  Simplified Chinese, and Traditional Chinese, while keeping command arguments
+  stable.
+- Restored the `0.53` content boundary: model output, tool output, session
+  transcripts, recovery branches, and background-job artifacts retain their
+  original text instead of being rewritten by heuristic secret redaction.
+  Credential masking remains in key-entry summaries and explicit diagnostic or
+  session-cleanup paths. Transcript-bearing session/job sidecars are kept
+  private (`0600`, with private job directories), and the retired
+  `redact_tool_output` setting is removed with a one-time upgrade notice.

+## [1.0.0] — 2026-06-03
+
+First stable release — a **ground-up rewrite in Go**. Not an upgrade of the `0.x`
+TypeScript line; a new codebase that becomes the default (`main-v2`).
+
+### Highlights
+
+- **Go kernel**: a single static binary (CGO-free), cross-compiled for
+  darwin/linux/windows on amd64 + arm64. Distributed via npm (the package wraps
+  the native binary), Homebrew (`esengine/reasonix` tap), and release archives;
+  no Node runtime needed to run it.
+- **Agent core**: the loop, built-in tools (read/write/edit/multi_edit/glob/grep/
+  ls/bash/web_fetch/todo_write), permission gate, sandboxed bash, and the
+  DeepSeek prefix-cache–oriented design.
+- **Subagents**: `task` plus explore/research/review/security_review skill agents.
+- **Skills & hooks**: Claude-Code-style skills (`internal/skill`) and hooks
+  (`internal/hook`), symlink-aware and slash-integrated.
+- **MCP client**: connect external servers over stdio / Streamable HTTP; reads
+  `[[plugins]]` and a Claude-Code `.mcp.json`.
+- **Code intelligence via CodeGraph**: a tree-sitter symbol/call graph
+  (`codegraph_*` tools) replaces embedding semantic search — no embedding service
+  or API cost. Fetched into a local cache on first use (or `reasonix codegraph
+  install`) and indexed in the background, so installs and startup stay fast.
+- **Plan mode** with evidence-backed step sign-off (`complete_step`).
+- **Memory**: `REASONIX.md` hierarchy + auto-memory, folded into the cache-stable
+  prefix.
+- **ACP** (`reasonix acp`) and an HTTP/SSE server frontend; desktop app (Wails).
+
+### Fixed
+
+- **File encoding support restored** — GBK/GB18030 (and other non-UTF-8) files
+  can now be read, edited, and grepped correctly. The v2 rewrite had dropped
+  v1's encoding detection; files in CJK Windows charsets were silently misread
+  or rejected as binary. The read/edit/write round-trip now preserves the
+  original file encoding. (#2637)
+
+### Notes
+
+- Versions: the legacy TypeScript line stays in `0.x`; the Go line starts at
+  `1.0.0`. See [docs/MIGRATING.md](docs/MIGRATING.md).
+- Release archives ship a bare binary; CodeGraph is fetched on first use. Windows
+  support for the fetched runtime is unverified — install `codegraph` on PATH if
+  the auto-fetch doesn't resolve there.

-scope. Default-path tests can clear `REASONIX_HOME` without losing the test
-registry, while explicitly isolated Reasonix homes retain their own locks.
-
-`REASONIX_TEST_HOME` carries the scope to helper subprocesses. A helper that

-
-The environment variable alone cannot activate a test scope. Production
-executables still use the OS account's home for shared config locks.
-
-The guard removes its scratch home on normal completion. Scratch homes are
-created under the original home, so an interrupted run can still leave
-`.reasonix-test-home-*` directories; this is separate from persistent
-config-edit locks in the real `.reasonix/locks` directory.

 ## Submitting changes

-Reasonix ships on two lines (see the

-and each takes different changes:
-
-| Line | Branch | Takes |
-| --- | --- | --- |
-| 2.x | `studio` | Features and fixes: active development |
-| 1.x | `main-v2` | Bug fixes, provider/API compatibility, release/updater, security, platform stability |
-
-A fix that matters on both lines lands on `main-v2` and is reviewed for
-porting to `studio`; do not open the same PR against both.
-
 1. Fork the repository
-2. Create a feature branch from the branch your change targets
+2. Create a feature branch from `main-v2`
 3. Make your changes with tests
 4. Ensure `go test ./...` passes
 5. Ensure `gofmt -l .` shows no changes
-6. Submit a pull request to that same branch
-
-## Pull request policy
-
-**Related changes.** If you have several related changes of one pattern, a
-tracking issue plus one pull request is easiest to review.
-
-**Issue first for features.** A change that adds behaviour rather than fixing a
-defect should link an issue the maintainers have agreed to before the work
-starts. A fix for a reproducible defect may open directly, with the failing test
-in the PR. Documentation-only and test-only PRs are reviewed at lower priority.
-
-**Review tiers.**
-
- Changes under the `sensitive:` paths declared in `REASONIX.md` get a full
-  review plus a security review, regardless of author.
- Every PR carries the four sections of the PR template: Cause, Blast radius,
-  Neighbouring behaviours tested, Why this layer.
- The new test must fail without the change.
- A UI change (`desktop/frontend-next/src` or the website pages) fills the
-  template's UI section: screenshots before and after, light and dark, wide
-  and phone width.
- The same section carries the line "Entries moved, hidden or removed".
- Hiding or removing a visible control needs a linked issue and a release-notes
-  line naming it, and updates `docs/STUDIO_PARITY.md` for a 1.x feature.
- Review holds these; no check reads them.
-
-**Transparency.** The PR template has an optional checkbox for disclosing AI
-assistance. It is for transparency only and does not change how a change is
-reviewed.

-## What it is
-
-Reasonix is an open-source AI coding assistant. The program runs on your computer; the AI model is a service you configure, which receives what it reads. You describe a task in plain language; it reads code, edits files and runs commands and tests inside the project folder you choose, and shows you each step.
-
-You pick the model: a DeepSeek preset is built in, any OpenAI-compatible service is one config entry, and you pay the model provider directly.
-
-## What you get
-
- **Read, edit, run.** It reads code, edits files and runs tests and commands, all inside your project folder.
- **Permission levels.** Have it ask every time, or let everyday actions run on their own; your forbid rules always hold. To see the approach first, use plan mode: it starts work only once you approve.
- **Rewind.** A file is saved before it changes, so you can rewind by conversation turn without touching your git history. Only files its edit tools changed are covered, not what a shell command did.
-
-## 30-second start
-
-Download, add a model key, open a project. New here? Start with the Studio desktop app.
-
-1. Download and install the desktop app, Reasonix Studio, from the [releases page](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true).
-2. Open it and enter your model provider and key when asked.
-3. Open your project folder and write what you want, for example "add retry on failure to the http client".
-4. At the level you chose, it stops and asks before anything that needs your say-so. Allow it to continue, or refuse.
-
-Prefer a terminal? Download the `reasonix` command-line tool, run `reasonix setup` to pick a model, then run `reasonix`. See [Install](#install) and [Quick start](#quick-start).
-
-## Four ways to use it
-
- **Desktop app (Studio).** A graphical app; the best place to start.
- **Terminal.** A full-screen text interface; `reasonix run "task"` also works in scripts.
- **Browser.** `reasonix web` opens a web interface on your own machine.
- **Editor.** Install the extension in VS Code; other editors that support ACP (Agent Client Protocol, a common way for an editor to connect to an AI assistant) can connect to `reasonix acp`.
-
-All four are the same program underneath. What follows is for advanced users and contributors.
-
-## Use it from DeepSeek Harness
-
-DeepSeek Harness (`dsh`) can hand a task to Reasonix as a subagent over ACP. This repository publishes a plugin index for it:
-
-1. Run `reasonix setup` on the machine that runs `dsh`. In the DSH Web UI turn on Custom plugin markets (Plugins, More) and add this index in the Discover tab: `https://raw.githubusercontent.com/esengine/DeepSeek-Reasonix/studio/integrations/dsh-plugin/market-index.json`
-2. Install "Reasonix subagent" from it.
-3. Open the plugin's page and turn its switch on. While it is off the model has no `reasonix` tool and may run `reasonix -p` in its own shell, which looks like a delegation and is not one.
-
-Setup details, the permission policy and limits are in [Using Reasonix from DeepSeek Harness](./docs/DSH.md).
-
-## Versions
-
-Reasonix ships on two lines. See the [version roadmap announcement](https://github.com/esengine/DeepSeek-Reasonix/discussions/10748) for the reasoning behind the split.

 ## Install

-This branch is **Reasonix 2.x**. Its desktop app is Reasonix Studio; the CLI,
-Studio, and editor integrations all run the same local Reasonix engine.
+Choose the path that matches how you want to use Reasonix. The CLI/TUI,
+desktop app, and VS Code extension all use the same local Reasonix engine.

-### Reasonix Studio (2.x)
+### Path A: CLI / TUI

-Download the package for your platform from the latest
-[Studio release](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true)
-(tagged `studio-v2.*`; candidates such as `-rc.N` are marked as
-pre-releases):
-
-| Platform | Package | Architecture |
-| --- | --- | --- |
-| macOS | `.dmg` or `.zip` | Apple Silicon (`arm64`) / Intel (`amd64`) |
-| Windows | Installer `-installer.exe` or portable `.zip` | x64 |
-| Linux | `.deb`, `.rpm`, or `.AppImage` (download only) | x64 (`amd64`) / ARM64 (`arm64`, aarch64) |
-
-Every package ships with a `.minisig` signature, and the release carries
-`SHA256SUMS`. Once installed, Studio updates itself in place.
-
-The same release also carries the 2.x `reasonix` CLI as archives for
-`darwin|linux|windows × amd64|arm64`.
-
-The Android build ships on that release as `ReasonixMobile-<version>.apk`
-(`arm64`, Android 8.0 or newer). The kernel and the page run on the phone, and
-the agent reaches your servers over SSH; pairing with a computer is done by
-scanning the code it shows.
-
-The APK is signed with the Android release key rather than minisign, so it
-carries a `.sha256` and no `.minisig`.
-
-When that key is absent the build is named
-`ReasonixMobile-<version>-unsigned.apk`. Android refuses to install an unsigned
-package, so those builds stay a workflow artifact for whoever wants to sign one,
-and the release carries no APK at all.
-
-### Reasonix 1.x (stable)
-
-The 1.x CLI installs through npm on any supported platform, or Homebrew on
-macOS:
+Install the native binary through npm on any supported platform, or use
+Homebrew on macOS:

 ```sh
 npm i -g reasonix                  # any OS; pulls the prebuilt native binary

 ```

-The 1.x desktop app is on the
-[official download page](https://reasonix.io/?download=desktop#start). Windows
-installers are code-signed with a Certum code-signing certificate.
+Prebuilt archives (`darwin|linux|windows × amd64|arm64`) and `SHA256SUMS` are on
+every [GitHub release](https://github.com/esengine/DeepSeek-Reasonix/releases).

-### VS Code extension
+### Path B: Desktop app

-The extension does not bundle the CLI; it starts your local `reasonix acp`
-backend and adds native chat, editor context, tool-call approvals, model
-selection, and workspace sessions. Install the 1.x CLI first.

-## 它是什么
-
-Reasonix 是一个开源的 AI 编程助手。程序跑在你的电脑上；AI 模型是你自己配置的服务，它读到的内容会发给这个服务。你用大白话描述任务，它在你选的项目文件夹里读代码、改文件、跑命令和测试，每一步都摆给你看。
-
-模型你自己选：内置 DeepSeek 预设，其他兼容 OpenAI 接口的服务填一条配置就行，费用直接付给模型服务商。
-
-## 你能得到什么
-
- **读、改、跑**：读你的项目、改文件、跑测试和命令，都在你选的项目文件夹里。
- **权限分档**：每次都问你，或让日常操作自动放行；你设的禁止规则始终有效。想先看方案，就开计划模式，批准后它才动手。
- **可回退**：改文件前先存快照，按对话轮次回退，不碰 git 历史。只覆盖编辑工具改的文件，命令行命令造成的改动不在内。
-
-## 30 秒上手
-
-下载、填模型密钥、打开项目。第一次用，从桌面应用 Studio 开始。
-
-1. 从[发布页](https://github.com/esengine/DeepSeek-Reasonix/releases?q=studio-v&expanded=true)下载并安装桌面应用 Reasonix Studio。
-2. 打开应用，按提示填入模型服务商和密钥。
-3. 打开你的项目文件夹，写下想做的事，例如“给 http 客户端加上失败重试”。
-4. 按你选的档位，该问你的操作它会先停下来问；同意就继续，不同意就拒绝。
-
-更喜欢终端的话，下载 `reasonix` 命令行后运行 `reasonix setup` 配好模型，再运行 `reasonix` 即可。详见[安装](#安装)和[快速开始](#快速开始)。
-
-## 四种用法
-
- **桌面应用（Studio）**：图形界面，适合第一次使用。
- **终端**：全屏文字界面，也能用 `reasonix run "任务"` 在脚本里运行。
- **浏览器**：`reasonix web` 在本机打开网页界面。
- **编辑器**：VS Code 安装扩展即可；其他支持 ACP（Agent Client Protocol，编辑器接入某个 AI 助手的通用约定）的编辑器，可连接 `reasonix acp`。
-
-四种用法背后是同一套程序。下面的内容写给进阶用户和贡献者。
-
-## 在 DeepSeek Harness 里使用
-
-DeepSeek Harness（`dsh`）可以通过 ACP 把任务交给 Reasonix 作为子智能体去做。本仓库为此发布了一个插件索引：
-
-1. 在运行 `dsh` 的机器上先运行 `reasonix setup`。在 DSH 网页界面打开“自定义插件市场”（插件，更多），再到 Discover 页添加这个索引：`https://raw.githubusercontent.com/esengine/DeepSeek-Reasonix/studio/integrations/dsh-plugin/market-index.json`
-2. 从中安装“Reasonix subagent”。
-3. 打开这个插件的页面，把它的开关打开。关着的时候模型没有 `reasonix` 工具，可能改在自己的 shell 里直接运行 `reasonix -p`，看起来像委派，其实不是。
-
-配置细节、权限策略和限制见 [在 DeepSeek Harness 中使用 Reasonix](./docs/DSH.md)。

- The context window (projection, compaction, estimation) owns `windowState`;
-  the loop reaches it via `a.window()`, it reaches the loop via `windowHost`.
-  `window-state` fails any other read of `sess.win`.
- Judgements read structure, never wording: shell ASTs (`shellparse`), types,
-  contracts, tool schemas. Phrase tables and message sniffing have been retired
-  in batches (task-policy prose, the planner's approval phrases, the executor
-  handoff tables) because each one misfires on real input, and a misfiring
-  judgement inside a gate is worse than no gate. Security allow-lists are the
-  exception and stay. Something that can only be built by matching words does
-  not get built — say what is missing instead of guessing at it.
- The other half of that rule: an error a caller must tell apart **carries an
-  identity** — a sentinel, a typed code — never a sentence. Only the producer
-  knows a deadline expired rather than a socket closed, and a message is where
-  that knowledge goes to die: the reader is left matching words, or with
-  nothing. Across HTTP the identity is a dotted code through `refuse`;
-  `refusal-path` fails a new `http.Error` in `internal/frontend/serve`, and the parity
-  test fails a code the frontend cannot say. Inside Go it is `errors.Is` on a
-  sentinel the wrapping preserves; `error-text` fails a new match against an
-  error message, following it one hop into a local because storing the text
-  first is what the direct form turns into.
- **Whoever first knows why an operation failed owns its class.** A transport
-  status is not a domain identity, and a display string is not a classification;
-  past that boundary a layer may project the class, never re-derive it. Both
-  directions were live: `catalog.go` answered 400 for a name nobody declared and
-  for a disk that would not write, so a failed store told the user their request
-  was wrong; `ServerRow` decided a connection was an authorisation problem by
-  matching `/401|403|unauthorized/` against prose an external MCP server wrote,
-  which the host had sanitised and truncated on the way through. Domain,
-  internal and dependency are three answers with three different things to do
-  next, and a caller that cannot tell them apart reports the last two as the
-  first.
- Failure attribution is host-owned state. When the host can determine why an
-  operation failed or stopped — truncation, timeout, unavailable context,
-  dependency skipping, policy refusal, output spill, argument parsing — that
-  cause goes to the model. Surfacing only the downstream symptom leaves it to
-  invent one, and the invented rule outlives the incident: a response cut at the
-  output limit reaches the model as "invalid arguments", and the session learns
-  to stop batching calls that were never the problem.
- A host-owned identity has to cross the model-visible boundary. Stable step
-  ids, typed error codes, boundary causes — anything the host expects the model
-  to cite must appear wherever that state is rendered for it. Telling the model
-  in a schema to prefer X while every concrete rendering shows only Y trains it
-  to use Y; `complete_step` said `step_id` PREFERRED while all four todo
-  renderers printed bare ordinals. Canonical dynamic state still stays out of
-  the cache-stable prefix — project the identities needed to act on it at the
-  turn tail.
- A metric is its definition, not its name. Before a number becomes a finding,
-  state what it counts, from which anchor, over which population, and what it
-  excludes. Three readings in one study died in that gap: a command of unknown
-  extent read as a proven write, the latest report's adjudication read as every
-  report's, and a syntactically accepted call read as a closed one. Each time a
-  convenient proxy had been left standing in for the state it was named after,
-  and each time the mechanism story built on it was wrong. A number without
-  those four lines is an observation, not a result.
- A constructed state is not a reachable one. Before a destructive test or a
-  counterfactual is reported as a defect, say who in production produces that
-  state, through which transitions, across which persistence boundary, under
-  whose authority, and whether a real run has been seen reaching it. A test that
-  assigns a private field proves the mechanism *given* the state and must be
-  reported as exactly that: `a.projectChecks` is written once at boot and never
-  again, so reassigning it stood in for a resume rather than demonstrating one,
-  and the bypass built on it was never shown to be production-reachable.
-  Severity is reachability times frequency times authority, not "can be
-  bypassed".
- A wire type the desktop re-declares by hand is held to the kernel's by
-  `wire-parity`, both directions: a field one side sends and the other cannot
-  read fails, and so does one it reads that nothing sends. The two are compiled
-  by different toolchains and meet only over JSON, so nothing else in the tree
-  notices when one of them grows a field. The pairs are declared in
-  `tools/repolint/wireparity.go`, never inferred — no spelling tells a mirrored
-  contract from a struct that merely carries json tags.
- "Add behavior to the controller so every frontend inherits it" is held by
-  `frontend-parity`: a capability one frontend already drives, a frontend whose
-  declared port carries it, and no call, is a missing edge, and the ratchet
-  counts edges. Which port each frontend drives is declared in
-  `tools/repolint/frontendparity.go`; a deliberate exception goes in the scope
-  table there with an issue and a reason, and costs what the edge cost, so the
-  table cannot become where debt disappears. The matrix is read from
-  `go/types` at one pinned build target, never from selector names — `Close`
-  and `Status` are capabilities and also stdlib methods, and a name match
-  records `os.File.Close` as a frontend driving `Lifecycle.Close`, a false
-  "wired" that hides real debt. How a verb is spelled — `/branch`,
-  `POST /branches` — is presentation and stays out of it.
- The desktop's presentation layer answers to canonical state and never
-  redefines it. Six rules, each held by a gate rather than by memory:
-  presentation reorders and reweights what the kernel owns but never restates
-  it; **mount is not a motion cause** — a fact enters once, and replay or
-  virtualization bringing its element back is not that fact happening again;
-  a search alias buys discoverability and never becomes a thing's identity;
-  when a setting takes effect is declared per block, from what its endpoint
-  does, never inferred from wording or handler names; ordering panels by
-  lifecycle moves them and must not remount them; and a control's identity
-  survives a change of where it is drawn — the settings sheet and the composer
-  render `chrome.preset` because that is one intent, not two.

 ## Comments

@@ -137,75 +40,17 @@ Default is none — the code is the truth. Write one only when the **why** is
 non-obvious: a hidden constraint, a workaround anchored to something verifiable,
 an invariant the type system cannot express, or an external-protocol quirk.

-A comment states the constraint that holds now. It does not narrate how the code
-got here: a reader who has never seen an earlier version must lose nothing, and
-past tense about this code's own behaviour is the tell — an external protocol's

-is the standard. No gate reads register — telling narrative from a statement of
-constraint needs a phrase table, which is the one thing this repo does not
-build — so this rule is held by review.
-
- **Stylesheets carry none.** A rule's selector and its declarations are the
-  whole statement. What a `.css` comment would have said goes to whichever of
-  two places can act on it: a constraint a component has to honour belongs in
-  that component, and a decision about the medium itself — a measured colour, a

-## Context projection
-
-Canonical dynamic state — the skill registry, the memory store — lives in its own
-owner, and what the model sees is a projection of it onto each request. The
-prefix was never where these belonged wrongly; freshness ownership was missing.
-
- **Prefix ownership.** Only declared prefix configuration may move the
-  cache-stable prefix; ordinary memory writes, skill writes and runtime facts
-  ride the turn. Pinned memory bodies are the one declared exception, because
-  pinning is a request to pay one cold start.
- **Projection freshness.** When canonical state changes, the next eligible turn
-  carries the new projection or can say why it is not owed. "Right after a fold,
-  or in the next session" is not an answer.
- **Projection ownership.** Whoever owns a dynamic fact owns the invalidation
-  that makes its projection owed again. A projection kept fresh because every
-  writer remembered to announce itself is one forgotten call from stale —
-  `skillSet.owedCatalog` asks the registry rather than waiting to be told.
- **Determinism.** The same canonical state and the same projection state
-  produce byte-identical model-visible bytes.
- **Detection is semantic.** Freshness may not rest on writer notification, on
-  mtime, or on which call path made the change. The registry answers from
-  canonical state, so a switch flipped and a file edited past every API are the
-  same question, and a change no projection renders is not a change.
-
-`internal/assembly/boot/context_projection_test.go` holds all five at the provider
-boundary, with the skills listing and the standing instructions as the two
-worked examples. A block is settled only once the turn carrying it reaches the
-runner: a turn blocked by a hook or refused by an extension after composing put
-those bytes nowhere, and clearing the debt there would leave the model holding
-state nobody sent it. A projection that has become empty is still owed once —
-otherwise the block the model already has goes on reading as current.

-## Vendor rates
-
-Official list prices live in one place: `officialRates` in
-`internal/contract/pricing/rates.go`, oldest generation first, the last being what a
-model charges today. A price change is an **append, never an edit** — the
-superseded rate is what lets an installed config be recognised as holding one
-of ours and brought forward, instead of quoting a retired rate for the rest of
-its life. `config` reads these through `pricing.CurrentRate` and
-`SupersededRates` and restates none of them; a table written twice is one that
-drifts, which is how a vendor's USD rate ended up published on one side only.
-
-`make pricecheck` reads each vendor's own page and compares it against that
-table, and reports how long ago a person last confirmed each one. It reaches
-the network, so it stays out of `make lint` and out of CI: run it before
-touching a rate and when a vendor announces a change. A page it cannot read
-exits non-zero — unread is its own verdict and never counts as agreement.
-
-## Curated presets
-
-A preset changing shape reaches the installs that already have the old one
-through `shippedPresets` in `internal/contract/config/preset_upgrade.go`: one declared
-shape per generation, and one upgrade that brings a matching entry forward. The
-guard is the whole shape — catalog, window, default — because an entry holding
-what we shipped is ours to move and anything else its user curated.
-
-A preset is also what settles which of its models read images. Probing an
-address a preset covers answers from that declaration, because reading a name
-misses every Kimi, Qwen, MiniMax and Claude model they declare and `deepseek-
-flash` spells nothing at all; the spelling is the last resort for an address
-nothing has declared, and stays a correctable suggestion rather than a claim.
-
-Three distinctions are load-bearing, and each was a separate migration function
-before they were written down. A window the shape did not name is the user's,
-so only a shape identified by its window moves one. `vision_models` **narrows**,
-so an upgrade marks only the models it adds and only where the preset says they
-read images. And an explicitly empty list is a choice — nothing here reads
-images — which is not the same as the nil that means nobody has said.

-effects; there is no second list to keep in sync.
-
-## Trust domain
-
-Three sets, kept apart because conflating them turns a performance number into a
-security claim: **VerificationRelevant** (state that can change whether a
-delivery claim holds), **Observable** (state the host can reconcile after an
-action, so it can say what that action did), **HostProtected** (state a
-capability/sandbox boundary makes unwritable). The invariant is
-`Writable ∩ VerificationRelevant ⊆ Observable ∪ HostProtected`:
-
-> Any state that can both be modified by an action and influence the delivery
-> claim must either be observable by the host or protected from modification by
-> host-enforced boundaries. An incomplete observation never establishes scope.
-
-Effects and state answer different questions and never stand in for each other —
-observation proves what an action did, verification proves what the resulting
-state satisfies — which is why `unproven_mutation` is settled only by
-observation, never by a check that ran afterwards.
-
-What follows bounds Observable today. It is not a restatement of the invariant:
-moving a number here must not move the promise.
-
- `scanWorkspace` walks the workspace and every granted extra root recursively,
-  skips VCS store dirs, and is `complete` only below 50k files in total. Over that, or past a walk error, it
-  establishes nothing and the mutation stays unproven.
- Symlinks are recorded by `Lstat`, so a write through one lands outside what
-  the walk compares. Confining the resolved target is the sandbox's job.
- `internal/safety/sandbox` confines writes to the workspace, configured extras, temp
-  and toolchain caches on macOS and Linux.
- On Windows a user-enabled write-restricted token bounds the *creation* of files
-  (create, append, overwrite, `mkdir`, HKCU writes, global git config, writes through links).
- There, deleting or renaming away an existing file is not bounded, and with the
-  setting off nothing the host enforces bounds `Writable`.
- The caches a command may write can be poisoned for the user's later unsandboxed
-  builds, on every platform.
- The governed host authorities are a *named* set — ssh-agent, docker, podman.
-  DBus, Wayland, X11, gpg-agent, keyrings and arbitrary sockets stay reachable,
-  so the claim is "these endpoints are governed", never "host IPC is isolated".
-
-`stateEpoch` tracks host-observed mutations, not an exact filesystem snapshot;
-unobserved external writers are a gap shared by the whole verification model. Go
-baseline test criteria use the toolchain's build overlay and therefore share
-ordinary verification's epoch semantics; the overlay is not a general filesystem
-view.
-
-A captured criterion may be superseded only by authority outside
-execution-mutable state; the current workspace, its tests, and the agent itself
-cannot authorize supersession.
-
-Two gaps follow and are open, not decided: a build that reads `.git` makes VCS
-state VerificationRelevant while the scan skips it, and on Windows a symlink out
-of the workspace is neither observed nor protected. Closing either means
-widening observation or narrowing writability — never widening what a check is
-taken to prove.
-
-## Sandbox dimensions
-
-`HostProtected` above is the delivery-level abstraction. Sandbox policy refines
-it into three independent protection dimensions. Their separation is empirical:
-measured bypasses showed that protection on one dimension cannot be assumed to
-imply protection on another.
-
- **Integrity** — what host state may be mutated. Expressed by write roots.
- **Confidentiality** — what host information may be observed. Expressed by
-  `ForbidReadRoots`.
- **Authority** — what host capabilities may be exercised *without* possessing
-  their secrets. Expressed by `HostAuthorities`.
-
-`ReadOnly` is therefore an Integrity property only; it makes no Confidentiality
-or Authority claim.
-
-Network transport and host authority are independent even when a backend
-primitive conflates them: on macOS, `(deny network*)` also cut ssh-agent, so one
-flag could not express "no internet, still sign".
-
-Filesystem visibility is not authority: denying `file-read*` on a socket did not
-stop a connect. Possession is not authority: the key can be unreadable while an
-agent still signs with it.
-
-A protection claim exists only where a backend has a demonstrated enforcement
-primitive for that dimension. Unsupported dimensions stay explicitly unsupported,
-because a claim that outruns its enforcement is worse than an absent one: it is
-believed.
-
-Windows enforces Integrity on file creation only, when the user turns it on.
-Deletion and rename, Confidentiality and Authority (the named pipes of ssh-agent
-and docker, COM and RPC services) are not enforced there.
-
-**Known unmeasured surface — macOS host-mediated delegation:** Apple Events and
-Mach-service lookup are not denied by the current allow-default profile. Prior
-`osascript` and `launchctl submit` probes were inconclusive; no delegation
-effect has been demonstrated. This surface is outside the currently governed
-host-authority endpoint set.

-# Reasonix Mobile — the Android shell
-
-Runs Reasonix as an Android app: the kernel ships inside the APK and starts on the
-device, the interface is the same `desktop/frontend-next` build the desktop Studio
-serves, and the agent reaches servers over SSH.
-
-This file is for people building it. What a person installing it needs — what it
-does, how to pair with a computer, what it cannot do — belongs in the release
-notes.
-
-## One command
-
-```bash
-./scripts/build.sh release     # or debug
-```
-
-Three steps, in this order:
-
-1. `build-kernel.sh` → `app/src/main/jniLibs/arm64-v8a/libreasonix.so`
-2. `sync-page.sh` → `app/src/main/assets/page/`
-3. `./gradlew assembleRelease`
-
-Output: `app/build/outputs/apk/release/app-release.apk`
-
-The kernel and the page are **inputs to packaging, not Gradle build steps**.
-Running `gradle assembleRelease` on its own fails on purpose and names the script
-that produces whichever input is missing (`requireBuildInputs` in
-`app/build.gradle`): an APK with no kernel in it should not be buildable by
-accident.

-| JDK | 21 (17 also works) |
-| Android SDK | `platforms;android-35`, `build-tools;35.0.0`, `platform-tools` |

-## Scripts
-
-| Script | What it does |
-| --- | --- |
-| `build.sh [debug\|release]` | The whole chain |
-| `build-kernel.sh` | Cross-compiles the kernel only (`GOOS=android GOARCH=arm64 CGO_ENABLED=0`) |
-| `sync-page.sh` | Builds the frontend, copies `dist/` into assets, copies `LICENSE` |
-| `verify-page.sh` | **No phone needed**: starts the real kernel against the packaged page |
-| `run.sh [debug\|release]` | `adb install`, launch, follow the log |
-
-`verify-page.sh` is the one to run after a change: it starts the kernel with the
-same arguments `Kernel.kt` uses (`--auth token`, `--token-file`, `--port-file`,
-`-page`) and checks that it binds a port and answers 200. Without a device, that
-is as deep as the chain can be verified.
-
-## Where the code is
-
-| File | Owns |
-| --- | --- |
-| `MainActivity.kt` | The WebView, the back gesture, downloads, external links, renderer restart |
-| `Kernel.kt` | Unpacking the page, starting and stopping the kernel, waiting for the port, health probes, logs, the workspace directory |
-| `KernelService.kt` | The foreground service that keeps a long turn alive |
-| `NativeBridge.kt` | `@JavascriptInterface`: what the page may ask the phone for |
-| `BrowserShellServer.kt` | Loopback HTTP server the kernel's browser tools drive the overlay WebView through |
-| `Downloader.kt` | Writing a kernel-produced file through the system document picker |
-
-The page reaches the shell through `window.reasonixHost` and `ReasonixNative`,
-defined in `desktop/frontend-next/src/port/host.ts` (`AndroidHost`).
-
-**Phone and desktop share one page build.** What differs only on a phone is
-decided at runtime, not by a second set of components. `phoneShell()` in
-`src/port/host.ts` and the `[data-shell="android"]` selector in `mobile.css` both
-read `<html data-shell="android">`, which `index.html` sets before the bundle
-loads.
-
-One attribute feeding both is what keeps style and components from disagreeing
-about what a phone is.
-
-## What the page may ask the phone for
-
-`NativeBridge` is reachable from whatever document the WebView holds, so every
-method that touches the device asks `trusted()` first.
-
-The activity answers by comparing the **main frame's** origin against the
-kernel's and against the one paired computer the person scanned a code for. A
-page that navigated elsewhere is not trusted, even though it may still hold the
-object.
-
-Five methods answer without the check — `version`, `systemTheme`, `safeArea`,
-`setLayerOpen`, `setRunning` — because they report back what the page already
-knows about its own window and grant nothing.
-
-`openInApp(url)` is the pairing decision, not a navigation one: it loads a URL in
-this window only for the origin the scanner just returned, and only once.
-Without that, any page holding the kernel origin could hand itself the bridge.
-
-External links leave through the browser. A non-web scheme is routed to the
-system only for `mailto:` and `tel:`; everything else is dropped, because an
-`intent://` URL can start an arbitrary exported activity with caller-supplied
-extras.
-
-## Permissions, and what they cost
-
-`MANAGE_EXTERNAL_STORAGE` — opening a folder on the phone as a workspace. The
-kernel is a Go binary: it opens real paths with `open(2)`, and SAF hands back a
-`content://` URI it cannot open.
-
-Requested from the folder-picker action, never at launch. Android shows no dialog
-for it and opens system settings instead.
-
-**There is no OS-level sandbox around this kernel.** The PR sets the sandbox to
-off on Android, so confining the agent to the chosen folder is Reasonix's own
-write-root check and nothing else. A shell tool with all-files access can reach
-all shared storage.
-
-`REQUEST_IGNORE_BATTERY_OPTIMIZATIONS` — Doze freezes the app group, which stops
-a turn that is still running. Asked once when a turn actually runs, never at
-launch, and the person can refuse. Refusing costs battery life during long turns
-and nothing else.
-
-**Google Play restricts this permission**: fine for a sideloaded build, a
-store-policy risk if this is ever listed.
-
-`FOREGROUND_SERVICE` / `FOREGROUND_SERVICE_DATA_SYNC` — keeping the kernel alive
-while the screen is off. `dataSync` is capped per 24 hours from Android 15. It is
-the closest honest description of "an agent is working".
-
-`CAMERA` — reading the pairing code a computer shows. Requested when the person
-asks to scan, never at launch. `ScanActivity` is not exported.
-
-`READ_EXTERNAL_STORAGE` / `WRITE_EXTERNAL_STORAGE` — the same folder walk below
-API 33. `maxSdkVersion`-gated; above 33 they are superseded by the permission
-above.
-
-`allowBackup=false` with explicit extraction rules, so a `keystore` or a token in
-app storage never leaves the device in a cloud backup.
-
-## Cleartext HTTP
-
-The kernel serves its page on `127.0.0.1:<port>`, and a paired computer serves
-the same page over its LAN address. Both are plain HTTP.
-
-Neither address can be written into a `network-security-config`: the port is
-chosen at start, the LAN address at scan time, and the format matches literals
-and domains, not subnets.
-
-So the config permits cleartext and the boundary is in the code instead.
-`shouldOverrideUrlLoading` sends every other http(s) origin to the browser, and
-the bridge answers only the kernel and the just-paired computer. A plaintext page
-on the LAN cannot become the document holding the bridge.
-
-## What goes into the APK
-
-| Content | Size | Why it is shaped this way |
-| --- | --- | --- |
-| `lib/arm64-v8a/libreasonix.so` | 45 MB | Go static binary, stripped. It is a `.so` rather than a file in `assets/` because only `nativeLibraryDir` is guaranteed executable — a binary copied to app storage fails on a device whose data partition is mounted `noexec`. |
-| `assets/page/` | 14 MB | The frontend build, including the Inter and Noto Sans SC fonts, `noCompress` |
-| `assets/LICENSE` | 1 KB | The repository's MIT licence, verbatim. MIT requires the notice and the licence text to accompany a binary distribution. |
-
-`assets/LICENSE` is generated by `sync-page.sh` from the repository's root
-`LICENSE`, not committed a second time: a checked-in copy drifts when the root
-file is updated.
-
-It sits in `assets/` rather than `assets/page/` because that directory is removed
-and rebuilt on every build.
-
-A release APK is about 31 MB.
-
-## Building
-
-**The Gradle wrapper is committed**, jar and all. `build.sh` refuses to run
-without `gradlew` rather than generating one from whatever `gradle` is on `PATH`:
-the dependency versions are part of the build.
-
-`gradle-wrapper.properties` pins `distributionSha256Sum`, so a mirror that serves
-a different distribution zip fails verification instead of being unpacked and
-run. Dependency repositories are the official ones only — a mirror belongs in a
-user-level init script.
-
-**Signing.** A release with no key configured comes out **unsigned**
-(`app-release-unsigned.apk`) with a warning. It used to fall back to the debug
-key, which produced an artifact that looked shippable and was signed by a
-per-machine key nobody chose: it could not install over the previous build.
-
-Point the build at a real key by writing `keystore/keystore.properties`
-(`storeFile`, `storePassword`, `keyAlias`, and optionally `keyPassword`) or by
-setting the matching `REASONIX_KEYSTORE*` environment variables. Key material
-stays out of the repository and out of build logs.
-
-Debug builds always use the debug key. Signing a debug build with the release key
-would let anyone who can read the keystore produce a build that installs over the
-shipped one under the same signature.
-
-**Non-ASCII checkout paths.** AGP refuses to build under a path with non-ASCII
-characters on Windows unless `android.overridePathCheck=true` is set. That is a
-property of one machine's disk layout, not of this project, so it is not in the
-repository's `gradle.properties`.
-
-Set it in a user-level `~/.gradle/gradle.properties` or pass
-`-Pandroid.overridePathCheck=true`.

-/**
- * The kernel's browser, as a loopback HTTP server.
- *
- * The Go kernel (`internal/platform/browser/shell.go`) drives a WebView by
- * POSTing JSON to a handful of paths on 127.0.0.1. This class is the other end
- * of that conversation: it accepts connections on a random port, parses the
- * minimal HTTP the kernel sends, and translates each path into an operation on
- * the overlay WebView.
- *
- * The server is deliberately tiny — no connection pooling, no keep-alive, no
- * chunked encoding — because the kernel is its only client and sends one
- * request per connection. A `ServerSocket` accept loop on a daemon thread is
- * the whole transport; each request is handled synchronously on its own thread.
- *
- * WebView operations must run on the UI thread. Each handler posts to the main
- * looper and waits on a latch, with a timeout that bounds the worst case (a
- * page that hangs the JS thread) to something the kernel's own 30-second client
- * timeout will not outlast.
- *
- * Memory note on `/screenshot`: a full-page `WebView.draw` into an ARGB_8888
- * bitmap at device resolution can reach tens of MB for a long page. The bitmap
- * is downsampled by a factor of 2 in each dimension before PNG encoding, which
- * keeps the peak allocation under ~10 MB for a typical 1080p viewport. The
- * original is recycled immediately after the downsample.

- * links to the browser, and the page's own download reaches the WebView's
- * `DownloadListener`.
- *
- * The one thing a phone must add is `importIntoHome`: the kernel runs on this

- * The camera, held open just long enough to read one pairing code.
- *
- * A phone that wants to drive a computer cannot type the code that computer
- * shows: it is a base64 fragment inside a URL, and the whole point of showing it
- * as a QR code is that nobody reads one aloud. So this is the way in — the same
- * gesture the computer's own dialog asks for, from the other side.
- *
- * The decode is ZXing rather than ML Kit on purpose. ML Kit needs Google Play
- * Services, and this app installs on phones whose HarmonyOS compatibility layer
- * has none: a GMS-backed scanner would work on a developer's phone and fail on
- * the device that needs it. ZXing core is pure Java, so the scanner behaves the
- * same on both.
- *
- * It returns the first code it reads and finishes. A pairing code is
- * single-use and short-lived, so "keep scanning after a hit" is not a feature —
- * it is a way to spend a code that a later frame would have discarded.
