+# Task acceptance authority and persistence
+
+The workspace task creation event retains its acceptance command. `resumeTask`
+and `task_acceptance` use that same command, and execute it in the requested
+workspace without changing the host process working directory. A nonzero,
+timed-out, or cancelled command cannot be replaced by passing contract evidence.
+A successful command remains authoritative even if contract criteria do not pass;
+the contract verdict remains in the audit history with its actual result.
+
+Native verdicts attest completion only after the acceptance ledger, contract
+status, and (for Task OS tasks) lifecycle acceptance have completed their real
+persistence barriers. These are separate appends, not a multi-file transaction.
+If a later lifecycle append fails, earlier successful audit records remain facts,
+but this incomplete contract settlement is compensated to its prior status. A
+previously completed lifecycle acceptance is never undone by this compensation.
+Custom verdict objects, source labels, and tool output strings carry no native
+commit attestation.
+
+Cancellation before the append dispatch prevents acceptance. Once the actual
+acceptance commit has begun, it completes its persistence sequence despite later
+cancellation. Only a successful completed commit wins that cancellation race;
+an IO failure carries no successful attestation. Tool execution scopes consume
+that attestation and stop remaining tools and model cycles in the accepting SDK
+agent. A nested SDK agent owns a separate scope, including in a shared workspace.
+This completion boundary does not synthesize a user abort.
+
+Each artifact append prepares a sidecar containing the previous confirmed byte
+length before changing the JSONL file. Files are fsynced on every platform; POSIX
+also fsyncs the directory entries. Node on Windows does not provide directory
+fsync, so Windows does not claim that additional directory durability guarantee.
+Failed writes attempt to truncate and sync their own tail under the existing
+workspace writer lock. If compensation also fails, the prepare sidecar remains:
+readers, including fresh processes, replay only its confirmed prefix. Invalid or
+unreadable prepare metadata produces a storage error. A later writer refuses an
+unresolved tail rather than guessing that it committed. Recovery of such a tail
+requires inspection and storage repair; there is no automatic marker deletion.
+
+Session recovery similarly claims the observed dead owner's exact generation
+before rechecking its token and liveness and replacing the recovery gate. Unknown,
+live, or stranded dead reclaim claims are retained and fail closed. A process
+crashing while it holds that claim can require operator recovery; recursively
+reclaiming the claim would recreate the unsafe replacement race.
+
+Public regressions cover persistent command failure across resume and tool
+acceptance, workspace cwd, native loop completion and nested-agent isolation,
+actual file/directory barriers, second and third append faults, failed rollback

@@ -45,3 +45,22 @@ Public regressions cover persistent command failure across resume and tool
 acceptance, workspace cwd, native loop completion and nested-agent isolation,
 actual file/directory barriers, second and third append faults, failed rollback
 read from a fresh Node process, cancellation, and competing recovery owners.
+
+Task artifact readers now hold the same generation-protected mutex as writers,
+so a cached tail cannot survive an intervening append rollback unnoticed. Time
+alone never evicts a live task lock. Identifiable legacy pid:nonce owners require
+a real ESRCH probe; unknown ownership is retained. Nested reads reuse only an
+active owner, and inherited callbacks must reacquire after that owner releases.
+Nested workspaces retain their active parent ownership without permitting a
+recursive write.
+
+A tool deadline still fires at its configured time. Only a native acceptance
+append already dispatched under the lock registers its remaining persistence
+settlement; before another mutation or model cycle, the SDK drains that actual
+settlement and consumes a successful attestation. Failed settlement grants no
+stop. Ordinary tool timeouts, evidence reads, and lock waits do not register this
+drain. A native append cannot begin later from an already ended tool scope. An
+already dispatched OS write/fsync that never returns can delay completion even
+after cancellation or a run budget: this is an explicit availability limitation
+of commit priority, not a claim of bounded cancellation for uninterruptible IO.
+No uncertain or failed write is reported as accepted to manufacture an exit.

Subject: [PATCH 032/114] fix(edit): include full file in partial-read
 rejection so next edit succeeds (O97)

The read-scope check is unchanged: an edit after an offset/limit read is
still rejected. The rejection now carries the full current file (same
100k-char cap and tool-output budget as read_file) and records it as a
full read, so models stop thrashing and bypassing via node -e. Files over
the cap get explicit guidance and stay locked.

Subject: [PATCH 035/114] fix(edit): partial-read refusal carries full file;
 block shell writes to refused files (O97)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Read-scope check unchanged. A partial-window refusal now attaches the full
file exactly as read_file presents it (withLineNumbers + read_file
presentToolOutput redaction) and records the read via recordFileState, so
the next edit matches. Credential files get no content/size/first line;
files over 100k chars or the caller's output budget get guidance only and
stay locked. Edit tools get read's output budget so ~20k-char files arrive
whole.

New src/safety/shell-write-detect.ts (detectShellWriteTargets,
canonicalPath, findProtectedWrite) for reuse by O94. Loop guard: after a
read-scope refusal without attachment or edit thrash, exec/bash writes to
that path (realpath-compared) are blocked with 已拦截, as are uncertain
commands (inline code, scripts) that name the file. Unlocks on full
read_file or successful edit; per-run state.

+ *
+ * Contract:
+ * - `targets`: absolute paths the command writes in a way we can see
+ *   (redirects, `tee`, `cp`/`mv`/`install`/`rsync`/`ln` destinations,
+ *   `dd of=`, `sed -i`, `perl -i`, `awk -i inplace`, `truncate`,
+ *   `git checkout|restore`, nested `sh -c`/`bash -c`/`eval`, and quoted
+ *   path literals inside `node -e`/`python -c`/... scripts that call a write
+ *   API).
+ * - `uncertain`: the command may write files we cannot see statically
+ *   (inline interpreter code, running a script file, `git apply`/`patch`,
+ *   `$(...)`/backticks, unbalanced quotes).
+ * - `mentions`: absolute form of every path-like word in the command,
+ *   including words inside quoted scripts. Callers combine it with
+ *   `uncertain` (e.g. block when uncertain AND a protected file is named).
+ *
+ * Not detected (documented limits): writes performed by a script file whose
+ * text is not in the command (`python fix.py`), paths assembled at runtime
+ * (string concatenation, env vars, base64), and anything outside POSIX-like
+ * shell syntax.

Subject: [PATCH 037/114] fix(O94): protected paths need one confirmation even
 in full mode

Writing/deleting/moving .git, .ssh, shell rc, .env, or Moss config always
asks once in interactive full mode and is denied in -p. Shell write
targets come from O97 detectShellWriteTargets; chmod/chown/chgrp are an
O94-only supplement. Default full mode is unchanged for normal paths.
Reads and git's own .git writes are not gated.

Subject: [PATCH 038/114] docs(release-policy): record v0.26.1 install smoke
 and publish path

latest=0.26.1 live on npm; temp-prefix install renders v0.26.1 (4cf10a9).
Also records the TTY-coupled cli-permission-defaults failure mode seen when
running directory-level npm publish from an interactive terminal.

Subject: [PATCH 042/114] fix(O94): -p/--print deny protected paths even when
 stdin is a TTY
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

QA BLOCK on #93: approval only took the headless deny path when
!stdin.isTTY, so moss -p on a real terminal fell through to
defaultAskUser and hung. Detect print mode from the printMode option
(wired from parsedArgs.print) or argv -p/--print, and deny immediately.

Also: rm maps to delete/「删除」 in the protected-path prompt; startup
full-mode banner no longer says "no approval prompts" (protected paths
still ask once). Exit code after deny stays with O98.

Tests: TTY+printMode and TTY+argv -p regressions with 2s hang timeout;
rm label; locale banner assertions updated.

Subject: [PATCH 044/114] fix(o98): export stable RunOutcome for O99

- add src/cli/run-outcome.ts: resolveRunOutcome + formatOutcomeLine
  status completed | incomplete | unverified (false check claims)
- oneshot -p path uses run-outcome for exitCode + last line
- tracker stays in run-completion; O99 imports from run-outcome
- tests cover unverified vs incomplete line prefixes

Rebase already on 58c9e3d6. Close QA/UX gaps on #94:

- formatOutcomeLine always emits a conclusion (完成 / 未完成 / 未验证 /
  验证失败 / 被拦); drop 未核实 wording
- status: completed | incomplete | verify_failed | blocked | unverified
  (soft unverified = exit 0; VERIFY_CMD / Stop = non-zero)
- VERIFY_CMD always recorded on tracker; continue once then re-verify;
  timeout/spawn not swallowed
- headless Stop hook blocked → non-zero + 被拦 line
- TUI shows outcome under the done stamp
- tests cover A–E plus completed / blocked / TUI line

Subject: [PATCH 046/114] feat(cli): O99 show real progress during long runs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Emit real progress at least every 60s on TUI and --print (stderr only):
tool start/end summaries, long-tool heartbeats via tool_progress, and
thinking-wait lines. Map existing tool_execution_progress heartbeats;
no empty working… slogans; unfinished runs get a clear last line on the
progress path (full false-success exit-code gate depends on O98/#94).
Display only — no safety/scheduling change.

Subject: [PATCH 047/114] test(O99): expect real tool progress in TUI live
 spinner
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Live spinner now shows the in-flight tool summary instead of Working….
Update tui-run-state and tui-shell assertions; narrow panes may clip
token/queue tails after the tool line.

Subject: [PATCH 048/114] fix(o99): wire progress footer to O98 run-outcome
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Consume resolveRunOutcome + formatOutcomeLine on the progress path
(no second outcome vocabulary). Unfinished stopReasons → Incomplete/
未完成 via O98; honest complete → non-empty 完成/Completed. Exit codes
remain owned by oneshot's O98 resolveRunOutcome (now on main).

Subject: [PATCH 049/114] fix(loop-guard): keep real casing in shell-write
 block paths (red macos CI)

findProtectedWrite returned the case-folded lock key, so on darwin/win32
the O97 guard relativised a lower-cased path against the real-case
workspace and displayed garbage like `../../t/moss-o97-lock-x/src/big.ts`
instead of `src/big.ts` (macos Test matrix red since #92; exec-write-lock
spec is the regression test). Matching still folds on darwin/win32; the
returned path is now the case-preserving canonical target, the thrash
display map is re-keyed the same way, and the guard base dir is
canonicalised for symlink/case symmetry. Windows failures in
exec-git-config are a pre-existing legacy issue, untouched here.

Normal completed exec/run_tests non-zero exits (lint/test fail) no longer
increment byToolFailure or trigger STOP calling it. Timeouts, start
failures, kills, and unusable empty output still count. Same-command
identical-output streaks use a separate counter with a change-code/command
hint (zh+en). Does not touch src/safety or raise failure limits.

Production exec ProcessError timeouts return "timed out after Nms" without
an Error: prefix, so is_error stayed false and loop-guard treated them as
success — falling into the identical-input generic message without 超时.

- isStringToolFailureResult: recognize timed out after / Command killed by
- recordToolLoopOutcome: classify VERIFY_SHELL faults even when isError=false
- e2e: production-shaped + real execTool timeout through executeOneToolCall

Subject: [PATCH 052/114] fix(o96): anchor shell fault classification to first
 line; drop isError=false text scan

Child stdout containing 'timed out after' / 'killed by SIG' / ENOENT /
'command not found' was misclassified as a tool fault. Only trust is_error
from execute-tool-call's anchored isStringToolFailureResult; exit_code: N
header => normal_nonzero regardless of stdout. Adds 4 negative tests (QA).

Subject: [PATCH 055/114] fix(o96): exit 126/127 = start failure with sanitized
 command name; mark exec timeout/kill structurally
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- classifyShellToolFailure: first-line exit_code 126/127 (and Command failed
  (exit 126|127)) => start_failure (未能启动). Stdout never classifies.
- Block copy names the missing command (parsed from shell 'not found' output,
  display-only, [A-Za-z0-9._/-]{1,64}) with next step 装依赖或改命令; otherwise
  generic 未能启动.
- Remove 'timed out after' / 'Command killed by' text regexes from
  isStringToolFailureResult; exec's ProcessError timeout/signal branch calls
  ctx.markResultError() so is_error comes from process facts, not stdout.

Subject: [PATCH 057/114] fix(config): O93 complete UX/QA gates for
 agent.reasoningBudget

Help (en/zh) explains meaning and cost/latency; text config show lists
value+source; untrusted projects drop reasoningBudget with the usual
skipped-settings tip; empty set lists off|adaptive|high; invalid
MOSS_REASONING_BUDGET warns once (stderr + configWarnings) then falls back.

Subject: [PATCH 058/114] fix(config): O93 untrusted project may only lower
 reasoningBudget

Untrusted folders keep a project agent.reasoningBudget when it is <= the
user effective value (unset user => adaptive); a raise is dropped into
ignoredProjectRouting so config show, -p, and TUI startup share the same
untrusted-folder notice. Help clarifies off = do not escalate (not disable
provider thinking). QA cases + revert-red covered in
test/config-reasoning-budget-o93.spec.mjs.

Subject: [PATCH 059/114] feat(O101): detect indirect writes to protected paths
 (inline/script/post-run)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three layers on top of O94/O97:
1) Inline python -c / node -e / bash -c with protected-path literals
2) Pre-run scan of workspace scripts (skip npm test/pytest/node --test)
3) Post-run metadata snapshot (mtime/size/hash only) → O98 incomplete

Best-effort interception, not a sandbox. No auto-restore; notices say
「已被修改」not「已拦截」. Delayed background writes are a known limit.

Subject: [PATCH 060/114] fix(safety): O105 redact Moss config on direct
 read_file execute

Defense in depth: readFileTool.execute now runs presentToolOutput for
isMossCredentialPath targets so apiKey never returns plaintext when
bypassing the agent post-hook. Project .moss/devices.json is treated as
a credential path alongside config.json. Directed tests cover execute
redaction, agent-path regression, and non-credential fixtures.

Subject: [PATCH 062/114] fix(safety): O107 follow credential realpath/symlink
 (O105 follow-up)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

isMossCredentialPath only path.resolve'd, so a workspace symlink into
.moss/config.json, devices.json, ~/.moss/*, ~/.config/moss/*, or
.apikey-key bypassed the O105 readFileTool.execute redaction gate.

Follow realpath (and readlink when dangling) like protected-paths /
canonicalPath; tighten isRawApiKeyFile the same way. Ordinary file
symlinks stay ungated. No kill-switch; O105 asserts unchanged.

Tests: symlink→config/devices redact; notes symlink plaintext;
dangling→config fail-closed; revert-red without follow.

Subject: [PATCH 063/114] fix(o108): wire O101 layer-3 protected-path snapshot
 to exec_background exit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Run the same takeProtectedPathSnapshot/diff helpers on background process
close/error (full exit), not when the tool returns a job id while still
running. Append 「已被修改」 notice to the buffer; fold hits into the run
outcome tracker via noteBackgroundProtectedPathMods so late exits still
mark incomplete / non-zero. Docs: exec_background covered; &/nohup and
post-Moss-exit writes remain known limits.

Subject: [PATCH 064/114] fix(hooks): reject non-string Moss hook command at
 config load (O89) (#104)

Validate hooks.*.command is a string in loadConfigFile so a bad object/array/
number/boolean/null never reaches formatHookFailure as [object Object].
Error copy (en/zh) includes the config path and event index; add focused tests.

Subject: [PATCH 065/114] fix(o109): soft Unverified exits 9
 (ExitCode.INCOMPLETE) (#105)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When -p ends with「未验证」/ Unverified (claimed checks passed but none
ran this session), process exit is now 9 instead of 0 so scripts can tell
failure/unverified from success. Last-line copy unchanged; Completed and
pure Q&A still exit 0; verify_failed / incomplete / blocked stay non-0.

Subject: [PATCH 067/114] fix(config): register
 MOSS_TOOL_LOOP_SAME_COMMAND_LIMIT in config env (O112) (#108)

moss config env is the authoritative MOSS_* reference. O96 added
MOSS_TOOL_LOOP_SAME_COMMAND_LIMIT in tool-loop-guard but never listed it,
so cli-config-env failed on main and the fail-fast suite stopped there.

Also register MOSS_LOCALE (read since O101 for protected-path notice locale);
without it the same coverage test stays red after the O112 key alone.

No loop-guard or test-allowlist changes.

Subject: [PATCH 068/114] fix(run-completion): EN/ZH claim parity (O110) (#107)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(run-completion): align ZH claim/request synonyms with EN (O110)

* fix(run-completion): ignore ZH Q&A/conditional frames for claim parity (O110)

Keep EN/ZH synonym alignment (修好↔Fixed, 检查全绿↔All checks green), but
do not treat question/hypothetical soft verbs (能不能修好 / 改好之后) as
expecting file writes, and do not treat explanatory/conditional 通过/全绿
(才算/表示/等…后; means / wait until … then merge) as success claims.

Adds EN/ZH paired cases C2–C7 (exit 0). Existing EN outcomes and O98
assertions unchanged; exit 9 semantics unchanged.

Subject: [PATCH 069/114] fix(run-outcome): omit stuck unknown; fill concrete
 class (O111) (#109)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(run-outcome): omit stuck unknown; fill concrete class (O111)

Incomplete / blocked / verify_failed last lines no longer fall back to
「卡在：未知」 / `stuck at: unknown`. When stuckAt is known (failed tool,
Stop hook, VERIFY_CMD, turn/budget class), append it; otherwise omit the
stuck half and keep only the main reason. Exit codes and O98/O109/O110
semantics unchanged.

* fix(run-outcome): omit empty reason; combine budget class with last step (O111)

formatOutcomeLine no longer falls back to a placeholder reason; an empty
reason is omitted like the stuck half. When an unfinished class (turn /
budget / …) and a tool step are both known, stuck reads e.g.
'run budget (read_file: src/a.ts)' / '运行预算（read_file: src/a.ts）' so
the -p stdout line and progress stderr line agree. Exit codes unchanged.

Subject: [PATCH 070/114] fix(ui): O91 Chinese display names for Moss-format
 hook events (#110)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a single copy table (hook-event-names.ts) so zh UI stderr/blocked/
help/TUI copy names hooks in Chinese (e.g. 停止前钩子) instead of bare
English event ids. Table values omit the 「钩子」 suffix; sentence
templates append it. Config keys, MOSS_HOOK_EVENT, and en UI stay
English. Directed tests cover the 8-spec table + formatHookFailure;
hooks-fail-closed zh expectations updated. No LITERAL_TOKENS expansion;
src/safety untouched.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

* fix(run-outcome): label safety block as 被拦; pass progress tracker (O113)

Safety/approval denials on incomplete runs now use 「被拦：…」 / `Blocked by: …`
with the tool/command instead of looking like a normal 「卡在：」. Non-block cases
(tool fail, zero writes, budget) stay 「卡在」 or omit — never mislabeled.

Progress stderr (output.ts done) passes the progress completionTracker into
formatProgressOutcomeLine so budget-exhausted lines match stdout, e.g.
「卡在：运行预算（read_file: …）」.

Exit codes and src/safety unchanged; O111 omit-unknown preserved.

* test: track O91 Stop zh display name (停止前钩子) in O111/O113 specs

Subject: [PATCH 073/114] fix(provider): O114 retry mid-stream stalls;
 inter-event idle default truly 60s (#113)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(provider): O114 retry mid-stream stalls; inter-event idle default truly 60s

- pi-ai-watchdog: inter-event idle no longer Math.min()'d with the 45s
  first-event deadline; default 60s, env overrides independent. Error
  reports the timeout of the phase that fired.
- classifier: PiAiFirstEventTimeoutError phase=inter -> retryable timeout,
  retried within existing llm-call budget (maxLLMRetries default 2 = up to
  2 retries). Exhausted -> LlmRetriesExhaustedError, PROVIDER_UPSTREAM_ERROR.
- phase=first untouched.
- test: o114-stream-stall-retry.spec.mjs; pi-ai-watchdog.spec pins inter env.

* fix(o114): stall retries actually fire on MossAgent path; honest exhausted outcome

- llm-provider-stream-adapter: keep original error (non-enumerable) on the
  error event; stream helper rethrows a phase=inter stall as-is so the
  retry policy sees it (previously flattened to non-retryable MossError).
- agent-error-outcome: exhausted mid-stream stall -> recoverable:false
  (scoped; other wrapped errors unchanged).
- watchdog: inter message starts with 上游流停滞 and carries an English
  'Upstream stream stalled' sentence.
- -p / progress footer: exhausted stall says 上游流停滞 / upstream stream
  stalled instead of generic 'error during execution'.
- tests: explicit default env clear; recoverable=false; process-level
  json + -p zh/en exit 6 spec.

Subject: [PATCH 075/114] fix(safety): O103 pre-block dangling symlinks,
 curl/wget output, git core.hooksPath (#115)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(safety): O103 pre-block dangling symlinks, curl/wget output, git core.hooksPath on protected paths

* fix(safety): O103 blocked protected writes end Incomplete/被拦 exit 9

Root cause: approval gate denied the tool, but the completion tracker never
recorded a protected-path block, so resolveRunOutcome treated the run as
completed (exit 0) whenever the model claimed success.

- Track protected-path blocks on tool_end; drive incomplete + 被拦 / Blocked by
  from that record (not claim detection). L3 "modified" still wins if the file
  is written another way; user-approved writes stay completed.
- Drop spurious `$F` (git) mention when the download target resolved; unresolved
  `$OUT`/`$(…)` get one honest confirmation line. Pre-block git --config-env=
  core.hooksPath. Optional hooksPath wording.

Subject: [PATCH 076/114] fix(o106): treat Windows exit 9009 as start_failure
 like 127 (#116)

On win32, cmd.exe "command not found" returns 9009. Classify it the same
as 126/127 (launch failure) for loop-guard byToolFailure; non-win32 9009
stays normal_nonzero. Platform is injectable for tests. Missing command
name reuses the O96 safe-charset path.

- run-completion: classifySafetyBlock() records dangerous command, protected
  path, O97 partial-read edit, hook block, -p approval deny, workspace policy
  and sandbox refusals into tracker.safetyBlocks (gate: loop outcome
  denied/blocked or the exec tools' own refusal prefix). Partial-read block is
  cleared when the same path is later edited successfully.
- Loop-guard short-circuits (PM): tracker.loopGuardStops → Incomplete exit 9,
  stuck at 'exec failed to start (command `X` not found)', never Blocked by.
  Tool line copy 已拦截/Blocked → 已停止重试/Stopped retrying.
- run-outcome: one main cause + (+N more)/（另有 N 处）; names what was refused.
- JSON/stream-json: result is_error, error = same conclusion line,
  recoverable:false, exit 9.
- test/o121-safety-block-outcome.spec.mjs: process-level -p cases zh+en.

Subject: [PATCH 080/114] docs(readme): split the bilingual README into zh main
 + README.en.md

One 900-line file mixing both languages read as clutter. README.md is now
the Chinese document; the English mirror lives in README.en.md with its
own badges, promoted headings, and file-level language switchers.
Section parity: 15 sections + 6 subsections on both sides; split replayed
on top of the latest main so O109/O94/O101 entries carry over.

+
+Moss is a minimal, cross-platform coding agent harness **and** an Agent Task OS for robot
+development. It turns a sentence of intent into a state-machine task with machine-checkable
+acceptance criteria, runs it through one agent loop, and **refuses to call it done without a
+verdict backed by recorded evidence**. It talks to RDK / Linux robots over SSH, so "done" can
+mean _the board actually did it_.
+
+- TypeScript / ESM single package · Node ≥ 22.16.0 · Linux / macOS / Windows
+- No account, no cloud service, no telemetry — providers are plain HTTP endpoints
+- Four surfaces: full-screen TUI · readline REPL · headless CLI · embeddable SDK
+
+## Prerequisites
+
+Check Node first (**hard requirement: Node ≥ 22.16.0**):
+
+```bash
+node -v
+```
+
+If Node is missing or too old, install it first (copyable):
+
+- **macOS:** `brew install node@22`, or `nvm install 22 && nvm use 22` / `fnm install 22 && fnm use 22`
+- **Ubuntu / Debian:** NodeSource ([nodesource/distributions](https://github.com/nodesource/distributions)) or the same nvm / fnm commands
+- **Windows (PowerShell):** `winget install OpenJS.NodeJS.LTS`
+- **In China:** `npm config set registry https://registry.npmmirror.com`. For nvm's Node downloads, set `NVM_NODEJS_ORG_MIRROR=https://npmmirror.com/mirrors/node`
+
+On Node older than 22.16, `npm install -g @rdk-moss/agent@latest` (and the source-path `preinstall` / `prepare` hooks) **exits non-zero immediately**, prints the detected Node version and copyable upgrade commands (including the success-path `npm install -g @rdk-moss/agent@latest`), and **does not** leave a broken global `moss`. Node 22.16 ships with npm 10. Do not follow npm's notice to upgrade to npm 12: Node 22.16 does not support npm 12.
+
+### macOS
+
+Git requires the Xcode Command Line Tools. If `git` is missing, run `xcode-select --install`. Moss itself does not need a C compiler, and a failed optional native build of `cpu-features` still leaves a working `moss`. If the global prefix is not writable, use the user-level prefix below.
+
+### Windows
+
+Install Git for Windows. PowerShell's execution policy can block `moss.ps1`. Allow scripts for the current user only:
+
+```powershell
+Set-ExecutionPolicy -Scope CurrentUser RemoteSigned
+```
+
+Put `%APPDATA%\npm` on PATH. That is npm's default global bin directory on Windows.
+
+## Quick start
+
+**Recommended (one line)** when Node ≥ 22.16 is already installed:
+
+```bash
+npm install -g @rdk-moss/agent@latest
+moss --version
+moss
+```
+
+If an older unscoped `moss` package is already installed, run `npm uninstall -g moss` first. The two packages use the same `moss` bin, and npm stops with EEXIST. Do not pass `--force`. It leaves both the old package and `@rdk-moss/agent` installed, and a later `npm uninstall -g moss` removes the `moss` command.
+
+If npm reports EACCES on the global prefix, point prefix at your home directory, or use nvm (Node then lives under your home directory):
+
+```bash
+npm config set prefix ~/.npm-global
+```
+
+Add `~/.npm-global/bin` to PATH and open a new terminal.
+
+<details>
+<summary>Develop from source (optional)</summary>
+
+For contributors. `npm ci` runs `prepare` (Node check, then `npm run build`), so there is no separate build step:
+
+```bash
+git clone https://github.com/D-Robotics/moss.git
+cd moss
+npm ci
+npm install -g --install-links .
+moss
+```
+
+npm 11 may print `npm warn install-scripts`. `npm ci` may name `ssh2` and `cpu-features`. The following `npm install -g --install-links .` may also name `@rdk-moss/agent` (its `preinstall` and `prepare` scripts). The warning is harmless: ssh2 works without its optional native addon, and the global copy already contains `dist/`. Do not run `npm audit fix --force`. It changes dependency versions and breaks the install.
+
+</details>
+
+With no usable config, `moss` sets itself up in that screen (press a number to pick a provider, or Enter to use a key already in the environment; the value is not shown). The D-Robotics gateway is listed first and preselected (`https://ai-api.d-robotics.cc/v1`, default model `deepseek-flash`, key only). To keep the key out of the file, set the provider and then the variable name: `moss config set provider d-robotics`, then `moss config set apiKeyEnv <VAR>`. A file that names only `apiKeyEnv` is not configured: setup asks which provider, and the key is not sent to the default DeepSeek endpoint. Then, in the same session:
+
+```text
+look around this folder and tell me what it is
+```
+
+### Custom OpenAI-compatible gateway
+
+For a gateway that is not a built-in preset, use `openai-compatible`. These four commands set the provider, model, address, and the key variable name (`apiKeyEnv` stores the name, not the secret):
+
+```bash
+moss config set provider openai-compatible
+moss config set model your-model-name
+moss config set baseUrl https://gw.example
+moss config set apiKeyEnv MY_GATEWAY_API_KEY
+export MY_GATEWAY_API_KEY=your-key
+moss doctor
+```
+
+A trailing `/v1` on `baseUrl` is optional. Both `https://gw.example` and `https://gw.example/v1` work. Moss appends `/v1/chat/completions` itself and never produces `/v1/v1`. Do not include `/chat/completions`; it is not needed, and Moss strips it if it is present. `moss doctor` checks the provider, model, address, and whether the key variable is set.
+
+Inside Moss: give it a job (`@` to reference files, `!` for shell), `Shift+Tab` to cycle modes
+(`plan` = read-only planning), `Ctrl+V` to attach a clipboard image / Finder file / local path
+(macOS; Linux: wl-paste/xclip; Windows: PowerShell), `/help` for keys and commands.
+
+<details>
+<summary>Run the build output directly · one-shot mode · resume</summary>
+
+```bash
+node dist/cli.js --help                       # run the build output
+moss "check disk usage"                       # one-shot (or pipe: echo "list files" | moss)
+moss resume --last                            # continue the latest session
+moss --no-tty                                 # force the readline REPL
+```
+
+</details>
+
+## Upgrade
+
+If the `moss` command still comes from an older unscoped install, including `npm link`, run `npm uninstall -g moss` first. Otherwise a new global install stops with EEXIST even when `moss --version` already looks new.
+
+**npm global install** (recommended path):
+
+```bash
+npm install -g @rdk-moss/agent@latest
+```
+
+**From an existing source clone**, in the parent of that clone:
+
+```bash
+cd moss && git pull && npm ci && npm install -g --install-links .
+```
+
+`npm ci` rebuilds. `--install-links` installs that new copy into the global prefix, instead of only rebuilding the clone. `moss --version` includes the short commit and the build date, for example `moss v0.26.0 (e8dc2e3, 2026-10-10)`. A worktree with uncommitted changes at build time is marked `e8dc2e3+dirty`. The before and after strings differ.
+
+`moss update` prints the matching command: `@latest` for an npm global install, the clone upgrade line when it finds a checkout, and `git clone` only when neither applies. A global install only looks for a checkout in the current directory and in `./moss`. Point it somewhere else with `moss update --dir <clone>` or `MOSS_SOURCE_DIR`. It prints the commands and does not run them.
+
+## Uninstall
+
+```bash
+npm uninstall -g @rdk-moss/agent
+```
+
+That removes the command. These stay behind:
+
+- Config: `~/.config/moss` on Linux and macOS (`$XDG_CONFIG_HOME/moss` when that variable is set), or `%APPDATA%\moss` on Windows. Also check `~/.moss`
+- The npx cache: `~/.moss/cache/npx`
+- Per-project `.moss/` directories (tasks, sessions, project config)
+- The source clone
+- The npm cache, usually `~/.npm`
+- The native-build cache: `~/.cache/node-gyp`
+- An empty `@rdk-moss` directory left under the prefix: `$(npm prefix -g)/lib/node_modules/@rdk-moss` on Linux and macOS, or `%APPDATA%\npm\node_modules\@rdk-moss` on Windows
+
+Safe to delete: `~/.moss/cache/npx`, `~/.cache/node-gyp`, the npm cache (`npm cache clean --force`), that empty `@rdk-moss` directory, and the clone once you no longer need the source. Deleting `~/.config/moss`, `~/.moss`, or a project's `.moss/` also removes keys, settings, and task history. Delete those only when you want that data gone.
+
+## Board has no outbound network / proxy setup
+
+Lab and classroom RDK boards often **cannot** reach GitHub, npm, Node mirrors, or the model gateway directly (TCP timeouts). The first `git clone` hangs.
+
+**Required environment variables (official recommendation — these only):**
+
+```bash
+export HTTPS_PROXY=http://127.0.0.1:1080
+export HTTP_PROXY=http://127.0.0.1:1080
+export NO_PROXY=localhost,127.0.0.1,::1
+# Current Moss main (O83 / #81 onward) routes Node fetch through these proxies
+# automatically. Do NOT set NODE_USE_ENV_PROXY — that was a temporary workaround
+# on older tips and is not needed now.
+```
+
+Port and whether you need an `ssh -R` tunnel depend on your site.
+
+**First install on a board:**
+
+1. **git clone:** use `git clone --depth 1 https://github.com/D-Robotics/moss.git`. A full clone often fails with GnuTLS / early EOF on slow or proxied links.
+2. **npm:** in China you may `npm config set registry https://registry.npmmirror.com`. A registry mirror **does not replace** `HTTPS_PROXY` when the board still needs a proxy to leave the LAN.
+3. **Node:** many RDK images already ship Node ≥ 22.16. nvm’s install script needs `raw.githubusercontent.com` and will time out offline — prefer the system Node, or install via the proxy.
+4. **User-level prefix:** `npm i -g` as root writes under `/usr`. Prefer `npm config set prefix "$HOME/.npm-global"` and put that `bin` on PATH.
+
+**How to confirm the proxy works (both required):**
+
+1. The proxy log shows `CONNECT` to the model / gateway host; and
+2. End-to-end you get a **successful answer** (`moss -p "…"` exits 0 — not “network connection failed”).
+
+**CONNECT alone with a network failure is a FAIL.** For triage you can temporarily set `MOSS_NO_RDK_DOCS=1`. Root-cause work for “CONNECT without an answer” is backlog **O87**; this README does not replace that item. Treat connection errors as proxy / firewall issues — **not** “switch to a faster model”.
+
+## Why Moss
+
+A normal coding agent's definition of done is the model saying so. Moss makes that judgement an
+auditable machine process:
+
+```text
+task_define (goal + machine-checkable acceptance criteria)
+  → device_deploy / device_exec / run_tests (real execution)
+  → record_evidence (structured Expected / Observed / Result)
+  → task_acceptance (evaluate against the latest evidence per metric)
+```
+
+- **PASS can only come from a verdict provider** (command verdict > contract verdict) — model
+  prose is never an event.
+- Missing evidence = not done; `latest-wins` supports re-verification after a repair.
+- Every task runs the same event-sourced state machine:
+  `draft → planning → executing → verifying → diagnosing → repairing → reverifying → accepted | failed`.
+- The acceptance gate is built in: a run that defined a task but produced no verdict gets its
+  final answer intercepted once and corrected — it does not hijack indefinitely.
+
+Artifacts land in the workspace `.moss/`: `tasks.jsonl` · `task-events.jsonl` · `evidence.jsonl` ·
+`deployments.jsonl` · `acceptance.jsonl` · `task-failures.jsonl` · `task-repairs.jsonl`.
+
+## Capabilities
+
+**Coding.** Turn control, context compaction and budgets, nudges, loop guards, and **45 built-in
+tools** (incl. **12 SSH device tools**) covering files and patches, code search, processes and
+background jobs, web, diagnostics, tests, sub-agents, and the task contract; mutating tools go
+through approval. Sessions are saved, searchable, exportable, forkable; `/compact`, `/rewind`,
+`/diff`, `/review`.
+
+**Sub-agents.** `create_subagent` with scoped children (explore / plan / verify / full),
+background runs, `fan_out_subagents` with aggregated summaries, and worktree-isolated writers
+merged back via 3-way patch.
+
+**Robots (RDK first).** Read-only `device_info` · `device_processes` · `device_resources` ·
+`device_temperature` · `device_network` · `device_cameras` · `device_robotics_status` ·
+`device_file_read` · `device_file_list`; approved mutations `device_exec` · `device_file_write` ·
+`device_deploy`. Register a fleet and fan out:
+
+```bash
+export MOSS_DEVICE_HOST=<board> MOSS_DEVICE_PORT=22 MOSS_DEVICE_USER=root MOSS_DEVICE_PASSWORD=...
+
+moss device add rdk-01 192.168.1.10 --user root --kind rdk
+moss device fleet info --devices rdk-01,rdk-02,rdk-03 --concurrency 4
+moss --print "define a task: camera pipeline keeps 30 FPS for 60s; deploy, run, record evidence, accept"
+```
+
+Board manuals (flashing, pinouts, TROS / hobot_dnn, specs) come from the built-in rdk-docs MCP,
+defaulting to the pinned `rdk-docs-mcp@0.3.0` (BM25 + title fusion, `noGoodMatch`, `alt_queries`,
+and board filtering; default hits are title, url, anchor, and snippet, with scores only when
+`verbose`; `get_page` returns the matching section unless `full`). Moss connects it in the background by default, with or
+without a device target (`MOSS_DEVICE_HOST` or `.moss/devices.json` is not required),
+so a cold npx download does not block the interactive shell. To test an unpublished build, set
+`"rdkDocs": {"package": "../rdk-docs-mcp"}` or `MOSS_RDK_DOCS_PACKAGE` to an npm spec, local
+directory, or tarball. Overrides execute code; use only trusted sources. `MOSS_NO_RDK_DOCS=1`,
+`"rdkDocs": false`, or `"rdkDocs": {"enabled": false}` turns it off. A same-named `mcp.json` entry
+replaces the builtin. Tool features vary by package version, so Moss discovers names and schemas
+before use. If the server cannot be reached, this session does not look up manuals — there is no
+cache or offline copy. See [`docs/superpowers/plans/2026-10-09-rdk-knowledge-via-mcp.md`](docs/superpowers/plans/2026-10-09-rdk-knowledge-via-mcp.md).
+
+**Extensibility.** MCP client (stdio + streamable HTTP, lazy tool loading), lightweight skills
+(`.moss/skills/<name>/SKILL.md`, `$ARGUMENTS` interpolation), custom slash commands
+(`.moss/commands/<name>.md`), persona (`.moss/soul.md`), lifecycle hooks.
+
+**Embedding.** Headless output is a stable contract for scripts and CI; a task's exit code is 0
+**only when accepted**. A `-p` last line of `Unverified:` / 「未验证：」 (claimed checks passed but none ran this session) exits **9** (`ExitCode.INCOMPLETE`), distinct from honest success (0). Unverified shares exit 9 with incomplete; scripts tell them apart by the last line (`Unverified:` / 「未验证：」 vs `Incomplete:` / 「未完成：」):
+
+```bash
+moss --print "summarize this repository"
+moss --output-format json "..."     # or stream-json (system/init → assistant → user → result)
+
+moss task run --goal "create hello.txt containing MOSS_OK and verify its content" --accept "grep -q MOSS_OK hello.txt"
+moss task status && moss task timeline
+moss tasks list                     # read-only robotics artifacts
+```
+
+The `src/index.ts` export surface is a semver-protected contract, snapshotted by
+`test/sdk-contract.spec.mjs`; three runnable integrations live in `examples/` (`npm run examples`).

+
+Everyday slash commands: `/model` `/compact` `/goal` `/plan` `/review` `/doctor` `/diff`
+`/permissions` `/clear` `/help`. Shift+Tab cycles modes; `/plan` enters plan mode; `/goal <condition>`
+works until the condition is met and `/goal clear` cancels it. `/resume` restores a saved
+conversation; `/tasks` lists background shell jobs and sub-agents. Esc interrupts the current
+reply; a message typed during a run steers it, and queues above the composer when steering is
+refused (Up edits that queue). `/mode` `/steer` `/queue` `/loop` stay as hidden aliases for one
+version (`/loop` is now `/goal`). Without `--accept`, `/goal` proposes acceptance commands from
+test entry points that exist in the workspace (`package.json` test, Makefile, pytest, `go.mod`)
+and says so when it finds none. `/stop` (alias `/abort`) stops only background processes this
+session started. The hidden `/task` is the Task OS entry (status / timeline / resume / view /
+verify); `/task verify` takes one verdict without a model turn. A PASS still comes only from the
+verdict provider.
+
+Key flags: `-m/--model`, `--provider`, `--base-url`, `-C/--cd`, `-c/--config k=v`,
+`--read-only` · `--workspace-write` · `--full-access` (workspace-write confines Moss's own file tools; shell commands run normally without an OS sandbox), `--trust-device`, `--accept-edits`,
+`--ask-for-approval <p>`, `-p/--print`, `--json`, `--output-format <f>`.
+
+Key env vars (full list: `moss config env`): `MOSS_PROFILE` · `MOSS_WORKSPACE` ·
+`MOSS_SAFETY_MODE` · `MOSS_APPROVAL_POLICY` · `MOSS_MAX_AGENT_TURNS` · `MOSS_CONTEXT_TOKENS` ·
+`MOSS_BUDGET_MAX_*` · `MOSS_DEVICE_*` · `MOSS_NO_RDK_DOCS`.
+
+> **Gotcha:** model settings are config-only. `MOSS_MODEL` / `MOSS_PROVIDER` / `MOSS_BASE_URL` /
+> `MOSS_API_KEY` are read but ignored — use `moss setup` or `moss config set`.
+
+Without an explicit file, Moss reads the user config and merges `.moss/config.json` from the
+workspace as project defaults (the user file wins). `--config-file` or `MOSS_CONFIG_FILE` loads
+only that file, so the project `.moss/config.json` layer is not part of the run.
+
+## UI language
+
+**English is the default UI language.** Chinese is a complete, optional UI language. It covers
+chrome, help, errors, and setup text. Assistant replies still follow the language of the user's
+message.
+
+```bash
+moss --lang zh                         # this run only
+MOSS_LANG=zh moss                      # process env (a project .env cannot set this)
+moss config set language zh            # user config ~/.config/moss/config.json
+moss config set language auto          # default: Chinese only when the locale starts with zh
+```
+
+Precedence: `--lang` > `MOSS_LANG` > user config `language` > system locale. Neutral tags
+(`C`, `POSIX`, `C.UTF-8`) are not a language and fall through to the next of `LC_ALL`,
+`LC_MESSAGES`, and `LANG`. If none names a language, the UI stays English. A project
+`.moss/config.json` and a project `.env` cannot set the UI language.
+
+In the shell, `/language` (alias `/lang`) switches the session. `/language zh save` writes the
+user config. On a Chinese system locale that has not chosen yet, the first `moss setup` offers
+one line: press `e` to switch to English.
+
+## Safety and privacy
+
+- **Full by default since v0.26**: local writes and **reversible** device changes skip the
+  prompt. Destructive device operations (reboot, flashing, writes to `/boot` or `/etc`, network
+  changes, removing system packages, stopping ssh) still confirm. Full matches Claude Code's
+  "ask less by default", not `--dangerously-skip-permissions` against a robot board.
+- **Four interaction modes** (Shift+Tab cycles, or `/plan` to enter plan mode; `/mode` remains for one version):
+
+  | Mode             | Behavior                                                                                                                                                                |
+  | ---------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+  | `manual`         | mutations and device changes ask one by one                                                                                                                             |
+  | `acceptEdits`    | workspace file-tool edits auto-approve; shell and device changes still ask                                                                                              |
+  | `plan`           | read-only planning; mutations and device changes blocked                                                                                                                |
+  | `full` (default) | local writes and reversible device work skip the prompt; destructive device work confirms on a TTY and is refused headless. Deny rules and host hard blocks still apply |
+
+- **`workspace-write` is not an OS sandbox.** workspace-write confines Moss's own file tools. Shell commands run normally without an OS sandbox. `write_file`, `edit_file`, `multi_edit`, `move_file`, and `apply_patch` stay inside the workspace. `exec` is not wrapped in Landlock, bubblewrap, or seatbelt. A static scan rejects some out-of-workspace shell writes it can see (redirections, `cp`, `mv`); a child `node` or `python` process can still write outside, for example under `/tmp`. Shell safety is output redaction and write-back guards. An opt-in OS sandbox is specified in [`docs/design/os-sandbox.md`](docs/design/os-sandbox.md) and stays off.
+- **Permission rules** (`/permissions`, effective in any mode, deny beats everything incl. full):
+  - three levels `allow` / `ask` / `deny`, priority deny > ask > allow;
+  - syntax `ToolName(pattern)` with moss-native tool names:
+    `/permissions add deny "read_file(./.env)"`, `/permissions add allow "exec(npm run *)"`;
+  - session rules take effect on the next tool call; `/permissions persist` writes the user config
+    and survives restarts;
+  - `--read-only` / `MOSS_SAFETY_MODE=read-only` is a read-only ceiling that compresses any mode
+    including full.
+- **Host hard blocks never lift**: destructive host `exec` commands (`rm -rf /` …) and path
+  escapes stay blocked in full mode — full skips the asking, not the checking. The same shapes on
+  the device are not a permanent hard block: a TTY confirmation, an allow rule, or explicit trust
+  runs them for real.
+- **Protected paths (O94 + O101) are best-effort interception, not a sandbox**: direct writes, deletes or
+  moves of a protected path (e.g. `~/.ssh`, files inside `.git/`) by file tools or shell commands
+  need one confirmation even in full mode; `git`'s own writes to `.git/` do not. Shell detection
+  parses the command line (O97/O94) and, with O101, scans inline `-c`/`-e` code and workspace
+  scripts before run. Anything that still slips through is caught after the command by a metadata
+  snapshot (mtime/size/hash only — never file contents): the run is marked incomplete ("modified",
+  not "intercepted"), exit non-zero, no auto-restore. `exec_background` runs the same layer-3
+  check when the background process fully exits. Still not an OS sandbox; `&` / `nohup` delayed
+  writes inside a foreground command, and writes after the Moss process itself exits, remain known
+  limits.
+- **Trust a device** (any one; deny rules still win): `--trust-device` (this process only),
+  `MOSS_DEVICE_TRUST=full`, `permissions.deviceTrust=full`, or `permissions.trustedDevices` /
+  `MOSS_DEVICE_TRUST_DEVICES` (comma-separated host or device id). Answering `a` trusts only the
+  scope named in the prompt (for example `systemctl restart` or `stop` of that unit, or the same
+  command prefix) until the session ends. Reading `/etc/shadow`, private keys, `sshd_config`, or
+  `authorized_keys` is a `sensitive` tier: it still confirms, and the copy does not call it
+  destructive. Prompts and refusals follow the UI language (`--lang`, `MOSS_LANG`, or the user
+  config `language`; otherwise Simplified Chinese when the system locale starts with `zh`).
+  Every decision is appended to `.moss/evidence.jsonl`
+  (`metric: device_policy`) and, when a task is in progress, to its timeline as a `note`.
+  Policy: [`docs/superpowers/plans/2026-10-09-device-safety-policy.md`](docs/superpowers/plans/2026-10-09-device-safety-policy.md).
+- **Legacy keys** (one release of grace): `profile` / `trustedTools` / `deniedTools` /
+  `safetyMode` / `approvalPolicy` are translated on read (cautious→manual+read-only ceiling,
+  balanced→manual, autonomous→full, trustedTools→allow rules, deniedTools→deny rules); writing
+  them prints a deprecation notice — use the `permissions.*` block for new config.
+- Credentials come only from `.env` or the environment: never hardcoded, never logged, never
+  passed to child processes, never written to the device registry. No account, no cloud, no
+  telemetry.

-> One Intent → One Task → One Agent Loop → One Verified Result.
-
-Moss is a minimal, cross-platform coding agent harness **and** an Agent Task OS for robot
-development. It turns a sentence of intent into a state-machine task with machine-checkable
-acceptance criteria, runs it through one agent loop, and **refuses to call it done without a
-verdict backed by recorded evidence**. It talks to RDK / Linux robots over SSH, so "done" can
-mean _the board actually did it_.
-
-- TypeScript / ESM single package · Node ≥ 22.16.0 · Linux / macOS / Windows
-- No account, no cloud service, no telemetry — providers are plain HTTP endpoints
-- Four surfaces: full-screen TUI · readline REPL · headless CLI · embeddable SDK
-
-### Prerequisites
-
-Check Node first (**hard requirement: Node ≥ 22.16.0**):
-
-```bash
-node -v
-```
-
-If Node is missing or too old, install it first (copyable):
-
-- **macOS:** `brew install node@22`, or `nvm install 22 && nvm use 22` / `fnm install 22 && fnm use 22`
-- **Ubuntu / Debian:** NodeSource ([nodesource/distributions](https://github.com/nodesource/distributions)) or the same nvm / fnm commands
-- **Windows (PowerShell):** `winget install OpenJS.NodeJS.LTS`
-- **In China:** `npm config set registry https://registry.npmmirror.com`. For nvm's Node downloads, set `NVM_NODEJS_ORG_MIRROR=https://npmmirror.com/mirrors/node`
-
-On Node older than 22.16, `npm install -g @rdk-moss/agent@latest` (and the source-path `preinstall` / `prepare` hooks) **exits non-zero immediately**, prints the detected Node version and copyable upgrade commands (including the success-path `npm install -g @rdk-moss/agent@latest`), and **does not** leave a broken global `moss`. Node 22.16 ships with npm 10. Do not follow npm's notice to upgrade to npm 12: Node 22.16 does not support npm 12.
-
-#### macOS
-
-Git requires the Xcode Command Line Tools. If `git` is missing, run `xcode-select --install`. Moss itself does not need a C compiler, and a failed optional native build of `cpu-features` still leaves a working `moss`. If the global prefix is not writable, use the user-level prefix below.
-
-#### Windows
-
-Install Git for Windows. PowerShell's execution policy can block `moss.ps1`. Allow scripts for the current user only:
-
-```powershell
-Set-ExecutionPolicy -Scope CurrentUser RemoteSigned
-```
-
-Put `%APPDATA%\npm` on PATH. That is npm's default global bin directory on Windows.
-
-### Quick start
-
-**Recommended (one line)** when Node ≥ 22.16 is already installed:
-
-```bash
-npm install -g @rdk-moss/agent@latest
-moss --version
-moss
-```
-
-If an older unscoped `moss` package is already installed, run `npm uninstall -g moss` first. The two packages use the same `moss` bin, and npm stops with EEXIST. Do not pass `--force`. It leaves both the old package and `@rdk-moss/agent` installed, and a later `npm uninstall -g moss` removes the `moss` command.
-
-If npm reports EACCES on the global prefix, point prefix at your home directory, or use nvm (Node then lives under your home directory):
-
-```bash
-npm config set prefix ~/.npm-global
-```
-
-Add `~/.npm-global/bin` to PATH and open a new terminal.
-
-<details>
-<summary>Develop from source (optional)</summary>
-
-For contributors. `npm ci` runs `prepare` (Node check, then `npm run build`), so there is no separate build step:
-
-```bash
-git clone https://github.com/D-Robotics/moss.git
-cd moss
-npm ci
-npm install -g --install-links .
-moss
-```
-
-npm 11 may print `npm warn install-scripts`. `npm ci` may name `ssh2` and `cpu-features`. The following `npm install -g --install-links .` may also name `@rdk-moss/agent` (its `preinstall` and `prepare` scripts). The warning is harmless: ssh2 works without its optional native addon, and the global copy already contains `dist/`. Do not run `npm audit fix --force`. It changes dependency versions and breaks the install.
-
-</details>
-
-With no usable config, `moss` sets itself up in that screen (press a number to pick a provider, or Enter to use a key already in the environment; the value is not shown). The D-Robotics gateway is listed first and preselected (`https://ai-api.d-robotics.cc/v1`, default model `deepseek-flash`, key only). To keep the key out of the file, set the provider and then the variable name: `moss config set provider d-robotics`, then `moss config set apiKeyEnv <VAR>`. A file that names only `apiKeyEnv` is not configured: setup asks which provider, and the key is not sent to the default DeepSeek endpoint. Then, in the same session:
-
-```text
-look around this folder and tell me what it is
-```
-
-### Custom OpenAI-compatible gateway
-
-For a gateway that is not a built-in preset, use `openai-compatible`. These four commands set the provider, model, address, and the key variable name (`apiKeyEnv` stores the name, not the secret):
-
-```bash
-moss config set provider openai-compatible
-moss config set model your-model-name
-moss config set baseUrl https://gw.example
-moss config set apiKeyEnv MY_GATEWAY_API_KEY
-export MY_GATEWAY_API_KEY=your-key
-moss doctor
-```
-
-A trailing `/v1` on `baseUrl` is optional. Both `https://gw.example` and `https://gw.example/v1` work. Moss appends `/v1/chat/completions` itself and never produces `/v1/v1`. Do not include `/chat/completions`; it is not needed, and Moss strips it if it is present. `moss doctor` checks the provider, model, address, and whether the key variable is set.
-
-Inside Moss: give it a job (`@` to reference files, `!` for shell), `Shift+Tab` to cycle modes
-(`plan` = read-only planning), `Ctrl+V` to attach a clipboard image / Finder file / local path
-(macOS; Linux: wl-paste/xclip; Windows: PowerShell), `/help` for keys and commands.
-
-<details>
-<summary>Run the build output directly · one-shot mode · resume</summary>
-
-```bash
-node dist/cli.js --help                       # run the build output
-moss "check disk usage"                       # one-shot (or pipe: echo "list files" | moss)
-moss resume --last                            # continue the latest session
-moss --no-tty                                 # force the readline REPL
-```
-
-</details>
-
-### Upgrade
-
-If the `moss` command still comes from an older unscoped install, including `npm link`, run `npm uninstall -g moss` first. Otherwise a new global install stops with EEXIST even when `moss --version` already looks new.
-
-**npm global install** (recommended path):
-
-```bash
-npm install -g @rdk-moss/agent@latest
-```
-
-**From an existing source clone**, in the parent of that clone:
-
-```bash
-cd moss && git pull && npm ci && npm install -g --install-links .
-```
-
-`npm ci` rebuilds. `--install-links` installs that new copy into the global prefix, instead of only rebuilding the clone. `moss --version` includes the short commit and the build date, for example `moss v0.26.0 (e8dc2e3, 2026-10-10)`. A worktree with uncommitted changes at build time is marked `e8dc2e3+dirty`. The before and after strings differ.
-
-`moss update` prints the matching command: `@latest` for an npm global install, the clone upgrade line when it finds a checkout, and `git clone` only when neither applies. A global install only looks for a checkout in the current directory and in `./moss`. Point it somewhere else with `moss update --dir <clone>` or `MOSS_SOURCE_DIR`. It prints the commands and does not run them.
-
-### Uninstall
-
-```bash
-npm uninstall -g @rdk-moss/agent
-```
-
-That removes the command. These stay behind:
-
-- Config: `~/.config/moss` on Linux and macOS (`$XDG_CONFIG_HOME/moss` when that variable is set), or `%APPDATA%\moss` on Windows. Also check `~/.moss`
-- The npx cache: `~/.moss/cache/npx`
-- Per-project `.moss/` directories (tasks, sessions, project config)
-- The source clone
-- The npm cache, usually `~/.npm`
-- The native-build cache: `~/.cache/node-gyp`
-- An empty `@rdk-moss` directory left under the prefix: `$(npm prefix -g)/lib/node_modules/@rdk-moss` on Linux and macOS, or `%APPDATA%\npm\node_modules\@rdk-moss` on Windows
-
-Safe to delete: `~/.moss/cache/npx`, `~/.cache/node-gyp`, the npm cache (`npm cache clean --force`), that empty `@rdk-moss` directory, and the clone once you no longer need the source. Deleting `~/.config/moss`, `~/.moss`, or a project's `.moss/` also removes keys, settings, and task history. Delete those only when you want that data gone.
-
-### Board has no outbound network / proxy setup
-
-Lab and classroom RDK boards often **cannot** reach GitHub, npm, Node mirrors, or the model gateway directly (TCP timeouts). The first `git clone` hangs.
-
-**Required environment variables (official recommendation — these only):**
-
-```bash
-export HTTPS_PROXY=http://127.0.0.1:1080
-export HTTP_PROXY=http://127.0.0.1:1080
-export NO_PROXY=localhost,127.0.0.1,::1
-# Current Moss main (O83 / #81 onward) routes Node fetch through these proxies
-# automatically. Do NOT set NODE_USE_ENV_PROXY — that was a temporary workaround
-# on older tips and is not needed now.
-```
-
-Port and whether you need an `ssh -R` tunnel depend on your site.
-
-**First install on a board:**
-
-1. **git clone:** use `git clone --depth 1 https://github.com/D-Robotics/moss.git`. A full clone often fails with GnuTLS / early EOF on slow or proxied links.
-2. **npm:** in China you may `npm config set registry https://registry.npmmirror.com`. A registry mirror **does not replace** `HTTPS_PROXY` when the board still needs a proxy to leave the LAN.
-3. **Node:** many RDK images already ship Node ≥ 22.16. nvm’s install script needs `raw.githubusercontent.com` and will time out offline — prefer the system Node, or install via the proxy.
-4. **User-level prefix:** `npm i -g` as root writes under `/usr`. Prefer `npm config set prefix "$HOME/.npm-global"` and put that `bin` on PATH.
-
-**How to confirm the proxy works (both required):**
-
-1. The proxy log shows `CONNECT` to the model / gateway host; and
-2. End-to-end you get a **successful answer** (`moss -p "…"` exits 0 — not “network connection failed”).
-
-**CONNECT alone with a network failure is a FAIL.** For triage you can temporarily set `MOSS_NO_RDK_DOCS=1`. Root-cause work for “CONNECT without an answer” is backlog **O87**; this README does not replace that item. Treat connection errors as proxy / firewall issues — **not** “switch to a faster model”.
-
-### Why Moss
-
-A normal coding agent's definition of done is the model saying so. Moss makes that judgement an
-auditable machine process:
-
-```text
-task_define (goal + machine-checkable acceptance criteria)
-  → device_deploy / device_exec / run_tests (real execution)
-  → record_evidence (structured Expected / Observed / Result)
-  → task_acceptance (evaluate against the latest evidence per metric)
-```
-
-- **PASS can only come from a verdict provider** (command verdict > contract verdict) — model
-  prose is never an event.
-- Missing evidence = not done; `latest-wins` supports re-verification after a repair.
-- Every task runs the same event-sourced state machine:
-  `draft → planning → executing → verifying → diagnosing → repairing → reverifying → accepted | failed`.
-- The acceptance gate is built in: a run that defined a task but produced no verdict gets its
-  final answer intercepted once and corrected — it does not hijack indefinitely.
-
-Artifacts land in the workspace `.moss/`: `tasks.jsonl` · `task-events.jsonl` · `evidence.jsonl` ·
-`deployments.jsonl` · `acceptance.jsonl` · `task-failures.jsonl` · `task-repairs.jsonl`.
-
-### Capabilities
-
-**Coding.** Turn control, context compaction and budgets, nudges, loop guards, and **45 built-in
-tools** (incl. **12 SSH device tools**) covering files and patches, code search, processes and
-background jobs, web, diagnostics, tests, sub-agents, and the task contract; mutating tools go
-through approval. Sessions are saved, searchable, exportable, forkable; `/compact`, `/rewind`,
-`/diff`, `/review`.
-
-**Sub-agents.** `create_subagent` with scoped children (explore / plan / verify / full),
-background runs, `fan_out_subagents` with aggregated summaries, and worktree-isolated writers
-merged back via 3-way patch.
-
-**Robots (RDK first).** Read-only `device_info` · `device_processes` · `device_resources` ·
-`device_temperature` · `device_network` · `device_cameras` · `device_robotics_status` ·
-`device_file_read` · `device_file_list`; approved mutations `device_exec` · `device_file_write` ·
-`device_deploy`. Register a fleet and fan out:
-
-```bash
-export MOSS_DEVICE_HOST=<board> MOSS_DEVICE_PORT=22 MOSS_DEVICE_USER=root MOSS_DEVICE_PASSWORD=...
-
-moss device add rdk-01 192.168.1.10 --user root --kind rdk
-moss device fleet info --devices rdk-01,rdk-02,rdk-03 --concurrency 4
-moss --print "define a task: camera pipeline keeps 30 FPS for 60s; deploy, run, record evidence, accept"
-```
-
-Board manuals (flashing, pinouts, TROS / hobot_dnn, specs) come from the built-in rdk-docs MCP,
-defaulting to the pinned `rdk-docs-mcp@0.3.0` (BM25 + title fusion, `noGoodMatch`, `alt_queries`,
-and board filtering; default hits are title, url, anchor, and snippet, with scores only when
-`verbose`; `get_page` returns the matching section unless `full`). Moss connects it in the background by default, with or
-without a device target (`MOSS_DEVICE_HOST` or `.moss/devices.json` is not required),
-so a cold npx download does not block the interactive shell. To test an unpublished build, set
-`"rdkDocs": {"package": "../rdk-docs-mcp"}` or `MOSS_RDK_DOCS_PACKAGE` to an npm spec, local
-directory, or tarball. Overrides execute code; use only trusted sources. `MOSS_NO_RDK_DOCS=1`,
-`"rdkDocs": false`, or `"rdkDocs": {"enabled": false}` turns it off. A same-named `mcp.json` entry
-replaces the builtin. Tool features vary by package version, so Moss discovers names and schemas
-before use. If the server cannot be reached, this session does not look up manuals — there is no
-cache or offline copy. See [`docs/superpowers/plans/2026-10-09-rdk-knowledge-via-mcp.md`](docs/superpowers/plans/2026-10-09-rdk-knowledge-via-mcp.md).
-
-**Extensibility.** MCP client (stdio + streamable HTTP, lazy tool loading), lightweight skills
-(`.moss/skills/<name>/SKILL.md`, `$ARGUMENTS` interpolation), custom slash commands
-(`.moss/commands/<name>.md`), persona (`.moss/soul.md`), lifecycle hooks.
-
-**Embedding.** Headless output is a stable contract for scripts and CI; a task's exit code is 0
-**only when accepted**. A `-p` last line of `Unverified:` / 「未验证：」 (claimed checks passed but none ran this session) exits **9** (`ExitCode.INCOMPLETE`), distinct from honest success (0). Unverified shares exit 9 with incomplete; scripts tell them apart by the last line (`Unverified:` / 「未验证：」 vs `Incomplete:` / 「未完成：」):
-
-```bash
-moss --print "summarize this repository"
-moss --output-format json "..."     # or stream-json (system/init → assistant → user → result)
-
-moss task run --goal "create hello.txt containing MOSS_OK and verify its content" --accept "grep -q MOSS_OK hello.txt"
-moss task status && moss task timeline
-moss tasks list                     # read-only robotics artifacts
-```
-
-The `src/index.ts` export surface is a semver-protected contract, snapshotted by
-`test/sdk-contract.spec.mjs`; three runnable integrations live in `examples/` (`npm run examples`).

-
-#### Legacy whl only (verified HTTP 200)
-
-Only these two direct URLs appear in Moss docs. Moss **will not** auto-install packages.

-
-#### Missing libhbucp.so
-
-Usually a pip overlay of system hobot / hbm packages, or OS &lt; 3.5.0 running a new Model Zoo. **Do not** `pip install hbm_runtime`. Prefer an image ≥ 3.5.0 with the board-bundled runtime; if pip overwrote packages, uninstall the pip copies, reinstall `hobot-dnn` via apt, and run `ldconfig`. `moss doctor` warns on deprecated pip indexes and can optionally probe the whl URLs above.

-> `plugins` / `migrate` / `web` / `agent` belong to removed subsystems and fail loudly
-> in this build rather than silently falling back to chat. `moss <command> --help` is that
-> command's own usage.
-
-Everyday slash commands: `/model` `/compact` `/goal` `/plan` `/review` `/doctor` `/diff`
-`/permissions` `/clear` `/help`. Shift+Tab cycles modes; `/plan` enters plan mode; `/goal <condition>`
-works until the condition is met and `/goal clear` cancels it. `/resume` restores a saved
-conversation; `/tasks` lists background shell jobs and sub-agents. Esc interrupts the current
-reply; a message typed during a run steers it, and queues above the composer when steering is
-refused (Up edits that queue). `/mode` `/steer` `/queue` `/loop` stay as hidden aliases for one
-version (`/loop` is now `/goal`). Without `--accept`, `/goal` proposes acceptance commands from
-test entry points that exist in the workspace (`package.json` test, Makefile, pytest, `go.mod`)
-and says so when it finds none. `/stop` (alias `/abort`) stops only background processes this
-session started. The hidden `/task` is the Task OS entry (status / timeline / resume / view /
-verify); `/task verify` takes one verdict without a model turn. A PASS still comes only from the
-verdict provider.
-
-Key flags: `-m/--model`, `--provider`, `--base-url`, `-C/--cd`, `-c/--config k=v`,
-`--read-only` · `--workspace-write` · `--full-access` (workspace-write confines Moss's own file tools; shell commands run normally without an OS sandbox), `--trust-device`, `--accept-edits`,
-`--ask-for-approval <p>`, `-p/--print`, `--json`, `--output-format <f>`.
-
-Key env vars (full list: `moss config env`): `MOSS_PROFILE` · `MOSS_WORKSPACE` ·
-`MOSS_SAFETY_MODE` · `MOSS_APPROVAL_POLICY` · `MOSS_MAX_AGENT_TURNS` · `MOSS_CONTEXT_TOKENS` ·
-`MOSS_BUDGET_MAX_*` · `MOSS_DEVICE_*` · `MOSS_NO_RDK_DOCS`.
-
-> **Gotcha:** model settings are config-only. `MOSS_MODEL` / `MOSS_PROVIDER` / `MOSS_BASE_URL` /
-> `MOSS_API_KEY` are read but ignored — use `moss setup` or `moss config set`.
-
-Without an explicit file, Moss reads the user config and merges `.moss/config.json` from the
-workspace as project defaults (the user file wins). `--config-file` or `MOSS_CONFIG_FILE` loads
-only that file, so the project `.moss/config.json` layer is not part of the run.
-
-### UI language
-
-**English is the default UI language.** Chinese is a complete, optional UI language. It covers
-chrome, help, errors, and setup text. Assistant replies still follow the language of the user's
-message.
-
-```bash
-moss --lang zh                         # this run only
-MOSS_LANG=zh moss                      # process env (a project .env cannot set this)
-moss config set language zh            # user config ~/.config/moss/config.json
-moss config set language auto          # default: Chinese only when the locale starts with zh
-```
-
-Precedence: `--lang` > `MOSS_LANG` > user config `language` > system locale. Neutral tags
-(`C`, `POSIX`, `C.UTF-8`) are not a language and fall through to the next of `LC_ALL`,
-`LC_MESSAGES`, and `LANG`. If none names a language, the UI stays English. A project
-`.moss/config.json` and a project `.env` cannot set the UI language.
-
-In the shell, `/language` (alias `/lang`) switches the session. `/language zh save` writes the
-user config. On a Chinese system locale that has not chosen yet, the first `moss setup` offers
-one line: press `e` to switch to English.
-
-### Safety and privacy
-
-- **Full by default since v0.26**: local writes and **reversible** device changes skip the
-  prompt. Destructive device operations (reboot, flashing, writes to `/boot` or `/etc`, network
-  changes, removing system packages, stopping ssh) still confirm. Full matches Claude Code's
-  "ask less by default", not `--dangerously-skip-permissions` against a robot board.
-- **Four interaction modes** (Shift+Tab cycles, or `/plan` to enter plan mode; `/mode` remains for one version):
-
-  | Mode             | Behavior                                                                                                                                                                |
-  | ---------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-  | `manual`         | mutations and device changes ask one by one                                                                                                                             |
-  | `acceptEdits`    | workspace file-tool edits auto-approve; shell and device changes still ask                                                                                              |
-  | `plan`           | read-only planning; mutations and device changes blocked                                                                                                                |
-  | `full` (default) | local writes and reversible device work skip the prompt; destructive device work confirms on a TTY and is refused headless. Deny rules and host hard blocks still apply |
-
-- **`workspace-write` is not an OS sandbox.** workspace-write confines Moss's own file tools. Shell commands run normally without an OS sandbox. `write_file`, `edit_file`, `multi_edit`, `move_file`, and `apply_patch` stay inside the workspace. `exec` is not wrapped in Landlock, bubblewrap, or seatbelt. A static scan rejects some out-of-workspace shell writes it can see (redirections, `cp`, `mv`); a child `node` or `python` process can still write outside, for example under `/tmp`. Shell safety is output redaction and write-back guards. An opt-in OS sandbox is specified in [`docs/design/os-sandbox.md`](docs/design/os-sandbox.md) and stays off.
-- **Permission rules** (`/permissions`, effective in any mode, deny beats everything incl. full):
-  - three levels `allow` / `ask` / `deny`, priority deny > ask > allow;
-  - syntax `ToolName(pattern)` with moss-native tool names:
-    `/permissions add deny "read_file(./.env)"`, `/permissions add allow "exec(npm run *)"`;
-  - session rules take effect on the next tool call; `/permissions persist` writes the user config
-    and survives restarts;
-  - `--read-only` / `MOSS_SAFETY_MODE=read-only` is a read-only ceiling that compresses any mode
-    including full.
-- **Host hard blocks never lift**: destructive host `exec` commands (`rm -rf /` …) and path
-  escapes stay blocked in full mode — full skips the asking, not the checking. The same shapes on
-  the device are not a permanent hard block: a TTY confirmation, an allow rule, or explicit trust
-  runs them for real.
-- **Protected paths (O94 + O101) are best-effort interception, not a sandbox**: direct writes, deletes or
-  moves of a protected path (e.g. `~/.ssh`, files inside `.git/`) by file tools or shell commands
-  need one confirmation even in full mode; `git`'s own writes to `.git/` do not. Shell detection
-  parses the command line (O97/O94) and, with O101, scans inline `-c`/`-e` code and workspace
-  scripts before run. Anything that still slips through is caught after the command by a metadata
-  snapshot (mtime/size/hash only — never file contents): the run is marked incomplete ("modified",
-  not "intercepted"), exit non-zero, no auto-restore. `exec_background` runs the same layer-3
-  check when the background process fully exits. Still not an OS sandbox; `&` / `nohup` delayed
-  writes inside a foreground command, and writes after the Moss process itself exits, remain known
-  limits.
-- **Trust a device** (any one; deny rules still win): `--trust-device` (this process only),
-  `MOSS_DEVICE_TRUST=full`, `permissions.deviceTrust=full`, or `permissions.trustedDevices` /
-  `MOSS_DEVICE_TRUST_DEVICES` (comma-separated host or device id). Answering `a` trusts only the
-  scope named in the prompt (for example `systemctl restart` or `stop` of that unit, or the same
-  command prefix) until the session ends. Reading `/etc/shadow`, private keys, `sshd_config`, or
-  `authorized_keys` is a `sensitive` tier: it still confirms, and the copy does not call it
-  destructive. Prompts and refusals follow the UI language (`--lang`, `MOSS_LANG`, or the user
-  config `language`; otherwise Simplified Chinese when the system locale starts with `zh`).
-  Every decision is appended to `.moss/evidence.jsonl`
-  (`metric: device_policy`) and, when a task is in progress, to its timeline as a `note`.
-  Policy: [`docs/superpowers/plans/2026-10-09-device-safety-policy.md`](docs/superpowers/plans/2026-10-09-device-safety-policy.md).
-- **Legacy keys** (one release of grace): `profile` / `trustedTools` / `deniedTools` /
-  `safetyMode` / `approvalPolicy` are translated on read (cautious→manual+read-only ceiling,
-  balanced→manual, autonomous→full, trustedTools→allow rules, deniedTools→deny rules); writing
-  them prints a deprecation notice — use the `permissions.*` block for new config.
-- Credentials come only from `.env` or the environment: never hardcoded, never logged, never
-  passed to child processes, never written to the device registry. No account, no cloud, no
-  telemetry.
-
-### Quality gates and benchmarks
-
-```bash
-npm run check    # prettier + eslint (0 warning) + typecheck
-npm run test     # build + every test/*.spec.mjs (235 specs, run against dist/)
-npm run smoke    # CLI smoke: --version / --help / PTY startup
-npm run verify   # check + test + smoke — required before any release
-
-# Real terminals (tmux / GNU screen / Terminal.app); off by default, missing terminals are skipped
-npm run build && MOSS_REAL_TERMINALS=1 npm run test:filter -- --filter tui-real-terminals
-```
-
-Benchmarks stay out of git in `bench/results/`:
-
-- `npm run bench` · `npm run bench:ab -- reasoning-high` · `npm run bench:noise`: agent capability, A/B, noise band
-- `npm run bench:swe` · `npm run bench:tb`: locked SWE-bench Verified subset · Terminal-Bench
-- `npm run bench:deepswe`: DeepSWE v1.1 with the model held fixed against other harnesses (runs
-  through Pier; published scores in `bench/boards/deepswe-v1.1-harness.json`)
-- `npm run bench:device -- --dry` (or `--target sim` / `--target real`): RDK board-task success
-  rate. A row passes only when Moss's verdict passes and an independent probe matches the
-  evidence — see [`docs/bench/device-bench.md`](docs/bench/device-bench.md)
-- `npm run bench:tui-feel`: TUI feel · `node scripts/task-os-metrics.mjs`: Task OS metrics
-  (turns / tools / success rate)
-
-A version number states the **current capability level**: `main` is the rolling line, tags are cut
-only after `verify` is green and `examples/` pass for real — see
-[`docs/release-policy.md`](docs/release-policy.md).

Subject: [PATCH 087/114] test(readme): assert zh README.md and en README.en.md
 separately after split; ship README.en.md

ad58a7d7 split the README into Chinese README.md + English README.en.md and
turned ubuntu Test red. English sentences are now asserted in README.en.md,
Chinese ones in README.md, shared commands in both (no assertion dropped).
Ship README.en.md in the npm package and use absolute GitHub URLs for the
language links so they work on npmjs.com.

Subject: [PATCH 091/114] fix(O128,O122): partial-read edit gate holds on
 retry; read_file never answered from replay cache

- O97 attached body no longer stamps a full read (tool-helpers partialReadRecovery); loop-guard locks on every refusal
- every partial-read refusal ends with the same next step (en+zh)
- read_file metadata.noReplay: loop replay cache skipped so a full re-read registers (O122)
- process test with 48k-char file + small-file QA repro; O97 unit tests tightened

- shell-write-detect: expand $PWD/${PWD}/$HOME before resolving; run-time-built targets match a locked path by literal suffix (only adds blocks)
- findLoopReplay exported: noReplay only on read_file, other read-only builtins still replay (test)
- process tests: sed -i, cat > ./x, ../dir/x, tee, python, symlink alias, $PWD, $D, $(pwd), backtick all blocked after partial-read refusal
- credential files (.moss/config.json, .env, .apikey-key, *.credentials): no body on refusal or any resend

Subject: [PATCH 106/114] fix(safety): O127 cancel workspace-root cd exemption
 after a second dir change

QA B1: exemption checked only that the first cd operand was the workspace
root, so `cd <ws> && cd && node x`, `cd <ws> && cd $HOME && node x`, and
similar follow-up cd/pushd/popd/chdir (any operand) stayed silent. Count
directory-changing builtins; allow the exemption only when there is at most
one. Add P4 regression tests that go red when this guard is reverted.

Subject: [PATCH 109/114] O130: block pwsh/cmd writes into Moss config dir via
 env vars (P1 security) (#129)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(safety): O130 gate Windows/PowerShell writes into Moss config dirs ($env:/%VAR%/Set-Content/process.env)

* fix(safety): O130 gate PowerShell/env-form write targets into Moss config dir; block unresolvable write targets

- new src/safety/pwsh-write-targets.ts: write targets of Set-Content/Add-Content/
  Out-File/New-Item/Copy-Item/Move-Item/Tee-Object/Clear-Content (+ sc/ac/ni/cpi/mi/
  copy/move/tee/cp/mv), [IO.File]::Write*/Append*, and >, >>, 2>, *>, &>
- $env:X / ${env:X} / %X% / $X expanded from the current env (case-insensitive);
  unknown vars, vars assigned earlier on the same line, command substitution,
  relative targets after an unresolvable cd -> blocked as unresolved
- only write targets are examined: $ in args / reads never prompts
- inline interpreter env-concat detection scoped to node -e / python -c etc.
- UX copy for unresolved variable targets (reason + next step, zh/en)
- o94: set USERPROFILE alongside HOME (Windows os.homedir), no assertion change

* fix(safety): O130 close QA BLOCK gaps — abbrev flags, paren targets, writers, one-level nest

- Value-flag abbreviations match by PowerShell unique-prefix (-En/-Va/-Enc/-Fi)
  so they cannot steal the path positional slot
- Parenthesized expression write targets (Join-Path, string concat) always block
  as unresolvable
- Add writers: Set-Item, Export-Clixml/Csv, Invoke-WebRequest -OutFile, curl -o/-O,
  xcopy/robocopy, New-Object IO.StreamWriter
- One-level nested scan for &{}/.{} / pwsh -c / iex (same rules inside);
  -EncodedCommand always blocks; deeper → O148 + O143 L3
- Temporarily rename o130-*.spec.mjs → aa-o130-*.spec.mjs so Windows CI runs them
  before exec-git-config (pre-existing red) aborts the suite; proper fix O149 (P2)

* style: prettier on O130 pwsh-write-targets after main merge

* fix(O130): block EncodedCommand unique prefixes (-EncodedC/-ec/-e)

hasEncodedCommand only matched -enc or the full -EncodedCommand name, so
mid-prefixes (-EncodedC, -EncodedCom) and documented aliases (-ec, -en, -e)
passed. Match by unique-prefix of EncodedCommand (VALUE_FLAGS style) plus
-ec; tests cover mid-prefixes and go red when the old regex is restored.

Subject: [PATCH 113/114] fix(goal-verify): keep non-zero ProcessError a
 rejection so FAIL/one-continuation branch runs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Merging codex/studio-public-sdk introduced a .catch() that normalized a
plain non-zero VERIFY_CMD exit into a resolved value, recording the run
as passed (exit 0, no continuation turn) — breaking run-completion-o98
and the goal-loop case in dotenv-safety-env. Restore the main semantics.

Subject: [PATCH 114/114] test(goal-verify): expect honest non-zero exit and
 the re-verify pass after continuation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With the rejection semantics restored, a failing VERIFY_CMD now exits
ExitCode.INCOMPLETE (9) instead of 0, and the continuation turn
re-verifies (marker records exit 7 twice) — matching the documented
'the continuation always re-verifies' contract and O98 no-false-success.
