service, guards, executors, and backups - GitService via short-lived git processes (info, branch, stash, stage, commit, push -u, log, .git/info/exclude upkeep); never force or reset - BranchGuard enforcing protected branch patterns (main/master/release*) in code - BranchNameBuilder: agent/- with request-derived kebab slug - PathSandbox: workspace-relative only, no .. or absolute paths, .git/.agent blocked, symlink escape detection - CommandPolicy: deny list (format/shutdown/force-push/global-config/pipe-to-shell) plus configurable allow list for AutoSafe - Per-command executors (say/newfile/updatefile/editfile/deletefile/readfile/ runcommand/ask/commit/done) behind WorkspaceCommandExecutor with dry-run, Ask-mode diffs/confirmations, BOM preservation, and backup-before-change - BackupService into .agent/backups with undo-latest restore --- .../Models/Agent/AgentProgressEvent.cs | 10 + .../Models/Agent/ConfirmRequest.cs | 8 + .../Models/Agent/FileChange.cs | 28 +++

Subject: [PATCH 009/102] Add agent loop, session store, configuration, and
 system prompt

- AgentLoop orchestrating one turn in numbered steps: config load, git
  preconditions (repo check, dirty-tree continue/stash/cancel), protected-
  branch guard with agent-branch creation, session resume/new chat,
  stale-snapshot refresh, first message with system prompt + attachments,
  the conversation loop (wait -> guard -> execute with batch limits and
  skipped reporting -> results message), and an always-on snapshot refresh
  in finally
- Automatic format re-ask with correction template up to MaxFormatRetries,
  raw reply shown to the user when exhausted
- ConfigurationService: tolerant keyless.json (comments, case, trailing
  commas, string enums), default file written when missing, range validation
- SessionStore persisting chat URL/branch/turn in .agent/session.json
  (no-session is a KA_SESSION_NOT_FOUND failure, matching the Outcome
  package's rule that Data is never null)
- SystemPromptBuilder injecting limits into the embedded system-prompt.md
- KeylessAgentServiceFactory wiring everything by hand (no DI container)
- TurnLogger JSON-lines transcript, FileLoggerProvider for debug diagnostics
- 156 tests green including end-to-end loop tests with the fake provider

+You are KeylessAgent, an autonomous coding agent. You are talking to a local program (not a human) that applies your replies to a git repository on the user's machine. The human user sees only what you put in `@@say` blocks.
+
+## Language rule
+
+Everything you write is ENGLISH (say messages, commit messages, summaries). The only exception: file content inside `newfile`/`updatefile`/`editfile` blocks may be in any language the file needs.
+
+## Response format: AgentScript v1 ONLY
+
+Your final answer must be PURE AgentScript v1: a sequence of blocks followed by a final line `@@eof`. Nothing else. No prose, no Markdown, no code fences around the whole answer, no explanations.
+
+The web Search and DeepThink features are enabled and may be used for research and reasoning — but reasoning, search notes and citations must NEVER appear in the final answer. Any explanation for the user goes inside `@@say` blocks.
+
+If your response was rejected with `[KEYLESSAGENT FORMAT ERROR], resend the COMPLETE corrected response. Do not apologize or explain.
+
+## Commands
+
+A block starts with `@@ [argument]` on its own line and ends with `@@end`. Payload sections are delimited by marker lines that stand alone on their line: `<<>>`. If a file must contain a line equal to the end marker, use a nonce: `<<>>`. Command names are case-insensitive. Paths are relative to the workspace root and always use `/`.
+
+```
+@@say

+
+## Limits (hard, enforced by the program)
+
+- At most {{MAX_COMMANDS_PER_RESPONSE}} non-`say` commands per response. Extra commands are skipped and reported; resend them in your next response.
+- The whole response must stay under {{MAX_RESPONSE_CHARS}} characters. Each file payload must stay under {{MAX_FILE_CONTENT_CHARS}} characters. Split big files across several `editfile` responses if needed.
+- Command output sent back to you is capped at {{MAX_COMMAND_OUTPUT_CHARS}} characters (head and tail kept).
+- A turn processes at most {{MAX_ITERATIONS_PER_TURN}} of your responses. Keep going across several responses for big tasks — do not try to do everything at once.
+
+## Rules
+
+- `say` is the ONLY way you talk to the user. Use it before and between work steps.
+- Paths are workspace-relative with `/`. Never absolute, never `..`, never inside `.git` or `.agent`.
+- Never modify, commit or push on branches `{{PROTECTED_BRANCH_PATTERNS}}`. The program blocks it anyway; work on the agent branch `{{BRANCH_PREFIX}}*`.
+- Call `readfile` before editing a file you have not seen in this conversation.
+- Prefer `editfile` over `updatefile` for small changes.
+- After code changes, run the build/tests (`runcommand`) and fix what they report.
+- Use `commit` only when the user asked for it or when the task is finished. Commit messages are short English.
+- `runcommand` takes one command line; segments split on `&&`, `||`, `;`, `|` are each checked against the policy. Destructive commands are always denied.
+- End every completed task with `@@done`.
+
+## Context you receive
+
+- Every user request arrives together with two attachments describing the current project state: `tree-view-result.txt` (the file tree) and `code-dump-result.md` (file contents). Treat them as the source of truth about the workspace; they are refreshed after every turn.
+- After each executed batch you receive a `[KEYLESSAGENT RESULTS]` message: one result per command (number, command, target, status, output). Commands you did not send appear as skipped — resend them.
+- If a file you need is not in the dump, `readfile` it.
+
+Begin every response with a `@@say` block summarizing what you are about to do, then the commands, then either more `say` or `@@done`.

Subject: [PATCH 010/102] Add the keyless CLI: commands, Spectre UI
 implementation, and tool packaging

- SpectreAgentUserInterface: say messages as panels, progress through the
  status spinner, prompts for confirm/ask, colored +/- diffs before changes
- Commands: 'run ' (--dry-run, -v), interactive default command
  (prompt-per-turn session), 'resume ' (reuses .agent/session.json
  chat), 'undo' (restores newest backup batch), 'config' (prints effective
  keyless.json, writing defaults when missing)
- AgentCliRunner: shared spinner + branch/commit summary at turn end
- KeylessAgentServiceFactory.CreateSessionStore/CreateFileLoggerFactory;
  SingleProviderLoggerFactory for verbose diagnostics logging
- publish.bat calling the root publish.ps1; tool verified to pack (nupkg+snupkg)

 # KeylessAgent
-A coding agent that runs on your own logged-in DeepSeek web chat, so you need no API key. Drives your Chrome via Playwright, reads replies as a strict command language, and applies them to your workspace on a safe agent branch. .NET 10 CLI.
+
+**A coding agent that runs on your own DeepSeek login. No API key.**

+[![Downloads](https://img.shields.io/nuget/dt/ImanSoftware.KeylessAgent.Cli.svg)](https://www.nuget.org/packages/ImanSoftware.KeylessAgent.Cli)
+[![License: MIT](https://img.shields.io/github/license/ImanEstiri/KeylessAgent.svg)](LICENSE.txt)
+[![Build and test](https://github.com/ImanEstiri/KeylessAgent/actions/workflows/build-and-test.yml/badge.svg)](https://github.com/ImanEstiri/KeylessAgent/actions/workflows/build-and-test.yml)
+
+KeylessAgent is a .NET coding agent that does not use an API key. It rides on the DeepSeek web chat **you are already logged into** in your own Chrome: it opens a new chat, sends your request together with your project's tree and code dump, waits for the reply, and applies it to your workspace as a strict command language (AgentScript) — on a protected agent branch, never on `main`.
+
+## ⚠️ Terms-of-service and account-risk notice (read this first)
+
+KeylessAgent automates a web UI. **This may violate DeepSeek's Terms of Use and can get your account limited, throttled or banned.** The selectors that drive the page can break with any site update. This project is **not affiliated with DeepSeek** — the name is used only to describe compatibility. Use it at your own risk, on an account you accept losing.
+
+## What and why
+
+Every LLM coding tool wants an API key. If you already pay for (or use) DeepSeek's web chat, KeylessAgent turns that login into your agent backend:
+
+- **No API key, no billing setup.** The browser session you already have is the credential.
+- **Strict command language.** The model's reply must parse as [AgentScript v1](docs/agentscript-spec.md); anything else is rejected and re-requested automatically. Nothing outside the grammar ever executes.
+- **Workspace-aware.** Every request carries `tree-view-result.txt` and `code-dump-result.md` (generated by the two `.bat` files in your repo), so the model sees your actual project — filtered for noise, chunked to fit.
+- **Loop with feedback.** After each executed batch the agent sends per-command results (`[KEYLESSAGENT RESULTS]`) back to the same chat, so multi-step tasks iterate until `@@done`.
+- **Safety in code, not in the prompt.** Protected-branch guard, path sandbox, command policy, backups, approval modes — all enforced in C#, covered by tests.
+
+## Requirements
+
+- Windows (the workspace scripts are `.bat`; see [known limitations](#known-limitations))
+- [.NET 10 SDK / runtime](https://dotnet.microsoft.com/download/dotnet/10.0)
+- Chrome, started with remote debugging:
+  `chrome --remote-debugging-port=9222` (or let KeylessAgent launch a persistent profile automatically)
+- A DeepSeek account logged in to [chat.deepseek.com](https://chat.deepseek.com) in that browser
+- The two workspace scripts in your repo root: `tree-view.bat` and `code-dump.bat` (they generate the attachments; KeylessAgent never modifies them)
+
+## Installation
+
+KeylessAgent is a .NET global tool:
+
+```bash
+dotnet tool install --global ImanSoftware.KeylessAgent.Cli
+```
+
+Verify:
+
+```bash
+keyless --help
+```
+
+## Usage
+
+Run one task:
+
+```bash
+keyless run "Add xUnit tests for the markdown parser"
+```
+
+Or start an interactive session (each finished turn reuses the same chat):
+
+```bash
+keyless
+```
+
+Example output of one turn:
+
+```text
+────────────────────────────────────────────── KeylessAgent
+Workspace: G:\Projects\MyApp
+ℹ Ctrl+C cancels the turn.
+⠋ WaitingForReply reply 1
+╭─ DeepSeek says ───────────────────────────────╮
+│ I will add the tests now.                     │
+╰───────────────────────────────────────────────╯
+…diffs, command results…
+✓ Turn 1 finished on branch agent/20260101-0930-add-markdown-tests
+Commits:
+  • 3f2a9b1 Add MarkdownParserTests
+```
+
+Other commands:
+
+```bash
+keyless resume "continue with the failing test"   # next request in the saved chat
+keyless undo                                      # restore the newest .agent/backups batch
+keyless config                                    # show / create keyless.json
+keyless run "..." --dry-run                       # print what would happen, execute nothing
+keyless run "..." -v                              # write .agent/logs/diagnostics.log
+```
+
+The first time a command runs in a workspace it creates `keyless.json` (configuration) and `selectors.json` (editable chat selectors) — see [docs/configuration.md](docs/configuration.md).
+
+## How it works
+
+```mermaid

+    M -->|yes| O[Refresh snapshot bat files]
+    K -.retries exhausted.-> O
+    N -.iteration limit.-> O
+```
+
+The full loop, limits and error codes are documented in [docs/agentscript-spec.md](docs/agentscript-spec.md).
+
+## AgentScript in 30 seconds
+
+The model answers in blocks; anything else is rejected:
+
+```text
+@@say
+<<>>
+@@end
+@@newfile src/Foo.cs
+<<>>
+@@end
+@@done
+<<>>
+@@end
+@@eof
+```
+
+Commands: `say`, `newfile`, `updatefile`, `editfile` (FIND/REPLACE, must match exactly once), `deletefile`, `readfile`, `runcommand`, `ask`, `commit`, `done`. Everything the model writes is English; file content may be any language.
+
+## Safety model
+
+| Layer | Enforcement |
+| --- | --- |
+| Protected branches | `main`, `master`, `release*` are blocked in code before any file change, commit or push ([tests](src/tests/ImanSoftware.KeylessAgent.Tests)) |
+| Path sandbox | workspace-relative only; no `..`, no absolute paths, `.git`/`.agent` blocked, symlink escapes rejected |
+| Command policy | deny list (format, shutdown, force-push, `git config --global`, `curl \| sh`, …) plus configurable allow list |
+| Approval modes | `Ask` (confirm every runcommand/deletefile), `AutoSafe` (allow-listed only), `Auto` |
+| Backups & undo | every changed file is backed up to `.agent/backups`; `keyless undo` restores the newest batch |
+| Dry run | `--dry-run` executes nothing |
+| Transparency | full per-turn transcript in `.agent/logs`, diffs before file changes in Ask mode |
+
+Details: [docs/security.md](docs/security.md) and [docs/git-workflow.md](docs/git-workflow.md).
+
+## Known limitations
+
+- **Windows only** for now (snapshot `.bat` scripts, `tree` command). The engine itself is portable.
+- **Web-UI automation is brittle**: DeepSeek can change its DOM at any time; selectors live in `selectors.json` so they can be fixed without recompiling, but they will need fixing. See [docs/browser-automation.md](docs/browser-automation.md).
+- **Reply reading has not yet been verified against a live chat** (indentation of code blocks, toggle behavior, stop indicator). This is the top item to validate manually.
+- No captcha solving: if a captcha appears, the agent waits for you to solve it in the browser.
+- The chat's context limit ends long turns: the agent detects a dead session only indirectly (reply timeouts); a "start a new chat with a state summary" path is on the roadmap.
+- `Snapshot.Mode: TreeAndChanged` currently attaches the full tree plus a hint (changed-file diffing is on the roadmap).
+
+## Roadmap
+
+- [ ] Windows Forms desktop UI (Core is UI-agnostic; implement `IAgentUserInterface`)
+- [ ] Official-API provider behind `IChatProvider` (no browser)
+- [ ] Chat-exhaustion detection and automatic continuation in a new chat
+- [ ] `TreeAndChanged` snapshot diffing
+- [ ] Cross-platform snapshot scripts (PowerShell/shell)
+- [ ] Cycle detection between user confirmations

+# AgentScript v1 — grammar, commands, and error codes
+
+AgentScript is the only format the agent executes. A model reply is a sequence of **blocks** followed by a final `@@eof` line. Anything else is a format violation: the reply is rejected (nothing executes) and the model is asked to resend.
+
+## Grammar
+
+```ebnf
+response   := fence? block* "@@eof" fence? ;
+block      := "@@" command [ argument ] newline
+              section*
+              "@@end" newline ;
+section    := "<<<" NAME [ ":" nonce ] newline
+              content-line*
+              NAME [ ":" nonce ] ">>>" newline ;
+command    := "say" | "newfile" | "updatefile" | "editfile" | "deletefile"
+            | "readfile" | "runcommand" | "ask" | "commit" | "done" ;
+NAME       := "MSG" | "CONTENT" | "FIND" | "REPLACE" | "CMD" ;
+```
+
+Rules:
+
+- Command names are **case-insensitive**.
+- **Paths are relative to the workspace root and use `/`** — never absolute, never `..`, never backslashes, never inside `.git` or `.agent`.
+- Payload markers only count when they are **the whole line** (trimmed). File content may safely contain the same text mid-line.
+- **Nonce markers**: if a file must contain a line equal to its end marker, the model can use `<<>>`.
+- A surrounding Markdown code fence is tolerated and stripped.
+- Non-whitespace text outside blocks is a violation.
+- The agent numbers commands by their order in the response (`#1`, `#2`, …); the model does not number them.
+- Everything the model writes is **English**; the only exception is file content.
+
+## Commands
+
+| Command | Argument | Payloads | Semantics |
+| --- | --- | --- | --- |
+| `say` | — | `MSG` | Prints the message to the user. The only way the model talks. Does **not** count toward the batch limit. |
+| `newfile` | path | `CONTENT` | Creates the file. Fails (`KA_FILE_ALREADY_EXISTS`) if it exists. Missing parent folders are created. |
+| `updatefile` | path | `CONTENT` | Replaces the whole file. Fails if missing. BOM is preserved. |
+| `editfile` | path | `FIND`, `REPLACE` | Replaces the single occurrence of FIND. Fails unless FIND matches exactly once. BOM is preserved. |
+| `deletefile` | path | — | Backs up, then deletes (confirmed in Ask mode). |
+| `readfile` | path | — | Returns the file content as that command's result. |
+| `runcommand` | — | `CMD` | Runs one command line. Every segment split on `&&`, `||`, `;`, `|` is checked against the policy. |
+| `ask` | — | `MSG` | Asks the user; the answer becomes that command's result. |
+| `commit` | — | `MSG` | `git add -A`, commit, `git push -u origin `. Push failures are reported to the model. |
+| `done` | — | `MSG` | Ends the turn with a summary. |
+
+### Example
+
+```text
+@@say
+<<>>
+@@end
+@@newfile src/Greeter.cs
+<< $"Hello, {name}!";
+}
+CONTENT>>>
+@@end
+@@runcommand
+<<>>
+@@end
+@@done
+<<>>
+@@end
+@@eof
+```
+
+## Limits (enforced, injected into the system prompt)
+
+| Limit | Default | Behavior when exceeded |
+| --- | --- | --- |
+| `MaxCommandsPerResponse` | 5 | First N non-`say` commands execute; the rest are reported as `skipped` and resent by the model |
+| `MaxResponseChars` | 60000 | Reply rejected (`KA_LIMIT_RESPONSE_CHARS`); model told to split |
+| `MaxFileContentChars` | 40000 | Reply rejected (`KA_LIMIT_FILE_CONTENT_CHARS`) |
+| `MaxCommandOutputChars` | 8000 | Result output capped (head + tail kept, cut marked) |
+| `MaxFormatRetries` | 3 | After N invalid replies the turn stops and the user sees the raw last reply |
+| `MaxIterationsPerTurn` | 25 | Turn stops with a stop reason |
+
+## Results message
+
+After each executed batch the agent sends one message mapping every result to its command:
+
+```text
+[KEYLESSAGENT RESULTS] turn=3 batch=2
+--- result 1/4 | #1 newfile | src/Foo/Bar.cs ---
+status: ok
+--- result 2/4 | #2 editfile | src/Foo/Baz.cs ---
+status: error
+reason: FIND text matched 0 times (must match exactly once)
+--- result 3/4 | #3 runcommand | dotnet build ---
+status: ok | exit code: 0 | duration: 4.2s
+<<>>
+--- skipped 1 commands: batch limit is 4 per response, resend them next ---
+[END RESULTS]
+Continue with the next commands, or finish with @@done. Reply in AgentScript v1 only.
+```
+
+## Format corrections
+
+Invalid replies get an immediate, specific correction (nothing executes):
+
+```text
+[KEYLESSAGENT FORMAT ERROR]
+Your last response was rejected. Nothing was executed.
+Problems:
+- line 14: Unknown command "@@createfile".
+- Missing "@@eof" at the end (the response looks truncated).
+Your response looks truncated. Resend it in SMALLER pieces (fewer commands per response).
+Resend your COMPLETE response using only AgentScript v1. Do not apologize or explain. Do not add text outside blocks.
+```
+
+## Error-code catalog
+
+Every failure the agent reports carries a stable code.
+
+### Parsing / format
+
+| Code | Meaning |
+| --- | --- |
+| `KA_PARSE_UNKNOWN_COMMAND` | `@@` keyword is not a known command |
+| `KA_PARSE_STRAY_TEXT` | non-whitespace text outside blocks (or inside a block, outside a payload) |
+| `KA_PARSE_MISSING_EOF` | reply does not end with `@@eof` |
+| `KA_PARSE_TEXT_AFTER_EOF` | non-whitespace text after `@@eof` |
+| `KA_PARSE_UNTERMINATED_BLOCK` | block opened without `@@end` |
+| `KA_PARSE_MISSING_PAYLOAD` | required section (`MSG`/`CONTENT`/`FIND`/`REPLACE`/`CMD`) missing |

+# Architecture
+
+KeylessAgent mirrors the layout of [DepLens](https://github.com/ImanEstiri/DepLens): one solution, an `Abstractions` project with models and contracts, a `Core` project with all implementations wired by a hand-written factory, and UI projects that contain no business logic.
+
+## Layers
+
+```text
+┌────────────────────────────────────────────┐
+│ UI: ImanSoftware.KeylessAgent.Cli          │  Spectre.Console.Cli; implements IAgentUserInterface
+│     (later: Windows Forms project)         │  references ONLY Core
+├────────────────────────────────────────────┤
+│ Core: ImanSoftware.KeylessAgent.Core       │  AgentLoop + services (internal sealed classes)
+│        KeylessAgentServiceFactory          │  hand wiring, no DI container
+├────────────────────────────────────────────┤
+│ Abstractions                              │  models, enums, service contracts,
+│                                           │  IAgentUserInterface (the UI contract)
+└────────────────────────────────────────────┘
+```
+
+**Dependency rule:** dependencies point downward only. Core never references Spectre.Console, `System.Console`, or any UI library — everything the user sees goes through `IAgentUserInterface` (`Say`, `ShowProgress`, `ConfirmAsync`, `AskAsync`, `ShowDiff`). Playground and Tests reach Core internals through `InternalsVisibleTo`.
+
+## Services
+
+| Contract (Abstractions) | Implementation (Core) | Responsibility |
+| --- | --- | --- |
+| `IAgentScriptParser` | `Parsing/AgentScriptParser` | line-based state machine over AgentScript v1; line-numbered problems |
+| `IAgentScriptValidator` | `Parsing/AgentScriptValidator` | size limits + path shape |
+| `IResponseFormatGuard` | `Parsing/ResponseFormatGuard` | the single gate in front of execution |
+| `IReplyExtractor` | `Browser/ReplyExtractor` | final-answer text from a message's HTML (never the reasoning) |
+| `IPathSandbox` | `Execution/PathSandbox` | workspace-relative only; blocks `..`, absolute, `.git`/`.agent`, symlink escapes |
+| `ICommandPolicy` | `Execution/CommandPolicy` | deny list + allow list per segment |
+| `IWorkspaceCommandExecutor` | `Execution/WorkspaceCommandExecutor` | dispatches to per-command executors (say/newfile/updatefile/editfile/deletefile/readfile/runcommand/ask/commit/done) |
+| `IBackupService` | `Execution/BackupService` | `.agent/backups` batches; `keyless undo` |
+| `IGitService` | `Git/GitService` | short-lived `git` processes; never force/reset/branch-delete/merge |
+| `IBranchGuard` | `Git/BranchGuard` | protected-branch patterns enforced in code |
+| — | `Git/BranchNameBuilder` | `agent/-` |
+| `ISnapshotService` | `Snapshot/SnapshotService` + `SnapshotFilter` | runs the two `.bat` files; filters/chunks attachments |
+| `IResultFormatter` | `Agent/ResultFormatter` | `[KEYLESSAGENT RESULTS]` messages |
+| `IChatProvider` / `IChatSession` | `Browser/PlaywrightChatProvider` / `PlaywrightChatSession`, `Browser/FakeChatProvider` | the browser behind an interface; fake for tests/Playground |
+| `ISessionStore` | `Agent/SessionStore` | `.agent/session.json` (chat URL, branch, turn) |
+| `IConfigurationService` | `Configuration/ConfigurationService` | tolerant `keyless.json` load/validate/create |
+| `IAgentLoop` | `Agent/AgentLoop` | one call = one turn; orchestrates everything |
+
+## Result convention
+
+Every service method that can fail returns `Outcome` / `Outcome` (`ImanSoftware.Outcome`), with stable `KA_*` error codes (catalog: [agentscript-spec.md](agentscript-spec.md)). `Data` is only read after `IsSuccess` is checked — and because the package's `Data` throws on null, contracts never carry null data (e.g. "no session" is a `KA_SESSION_NOT_FOUND` failure).
+
+## Adding a new UI
+
+1. Reference `ImanSoftware.KeylessAgent.Core` only.
+2. Implement `IAgentUserInterface`.
+3. Create the loop via `KeylessAgentServiceFactory.CreateAgentLoop(loggerFactory)` and call `RunAsync(workspaceRoot, request, ui, dryRun, ct)` per request. Multi-turn interactive UIs simply call it repeatedly — the chat session is persisted and reused.

+# Browser automation
+
+The highest-risk part of KeylessAgent: driving the DeepSeek web chat with Microsoft.Playwright. This document explains what is automated, which selectors are used, and what still needs manual verification.
+
+## Connection
+
+1. **Default — attach to your Chrome**: you start Chrome with `chrome --remote-debugging-port=9222`; the agent uses `ConnectOverCDP` and reuses your logged-in profile. Nothing is stored, no passwords are ever typed.
+2. **Fallback — persistent profile**: if CDP fails, the agent launches Chromium with a persistent context under `%LOCALAPPDATA%\KeylessAgent\chrome-profile`. Log in once; the login persists.
+
+If the login page is detected, the agent prints a warning and waits (up to 5 minutes) for you to log in manually.
+
+## Selectors
+
+All selectors live in the workspace `selectors.json` (created from the embedded default on first run), each as an ordered fallback list — **editable without recompiling**. The default catalog was built from a real DOM sample of the chat page and prefers structural selectors over the obfuscated hashed class names (which change between releases):
+
+| Key | Default (first fallback) | Notes |
+| --- | --- | --- |
+| `InputBox` | `textarea[placeholder="Message DeepSeek"]` | also `textarea[name="search"]` |
+| `SendButton` | `div:has(> input[type="file"]) [role="button"].ds-button--filled` | icon-only button next to the hidden file input |
+| `FileInput` | `input[type="file"][multiple]` | accepts `.md`, `.txt`, `.bat`, `.cs`, `.json`, … |
+| `NewChatButton` | `[role="button"]:has-text("New chat")` | not present in the sample; multiple fallbacks |
+| `MessageItems` | `.ds-virtual-list [data-virtual-list-item-key]` | the list is virtualized: only newest messages exist in the DOM |
+| `AssistantMessage` | `.ds-message:has(.ds-markdown.ds-assistant-message-main-content)` | |
+| `FinalAnswer` | `.ds-markdown.ds-assistant-message-main-content` | never matches inside `.ds-think-content` |
+| `Reasoning` | `.ds-think-content` | excluded from every read |
+| `StopIndicator` | `[role="button"][aria-label="Stop"]` | not in the sample; several fallbacks |
+| `DeepThinkToggle` / `SearchToggle` | `.ds-toggle-button:has-text("DeepThink")` / `…("Search")` | state read from `aria-pressed` |
+| `LoginIndicator` | `input[type="password"]` | |
+
+**Not covered by the DOM sample**: the generating/Stop state, the New Chat button, and the login page. Those selectors ship with several fallbacks and log a clear error naming the missing selector — fix them in `selectors.json` when DeepSeek changes.
+
+## Reading replies — final answer only
+
+Each assistant message can contain **two** `.ds-markdown` blocks: the reasoning (`.ds-think-content`, headed "Thought for N seconds") and the final answer (`.ds-markdown.ds-assistant-message-main-content`). Only the **final answer of the newest assistant message** is ever read; the reasoning never reaches the parser (it would break it), the logs, or the chat.
+
+`IReplyExtractor` (unit-tested against fragments of the real sample) takes the newest message's HTML and returns only the final-answer text:
+
+- the reasoning subtree is skipped entirely,
+- inside code blocks only the `
` text is kept (the Copy/Download banner is dropped),
+- `<`/`&`/… entities are decoded,
+- text inside `
` is taken raw — indentation and newlines are preserved rather than reading the rendered `innerText` of the Markdown.
+
+**Completion detection**: the session waits while the stop/generating indicator is visible, then reads the final-answer element twice one second apart and accepts it when unchanged. A message with reasoning but no final-answer element yet never counts as a reply.
+
+## Sending
+
+- Long text is inserted with a whole-text insert (`keyboard.insertText`), **never per-character typing**.
+- A local rate limiter enforces `MaxMessagesPerMinute` plus random delays between `MinDelayMs`/`MaxDelayMs`.
+- Attachments are first **uploaded** through the chat's file input (`SetInputFilesAsync` on files written to `.agent/attachments`). When upload is impossible or the content is too big, it is **pasted** into the message; oversized dumps are split at file boundaries into consecutive parts.
+
+## Toggles
+
+Before the first message of every new chat, both toggles (DeepThink, Search) are checked via `aria-pressed` and clicked only when they disagree with `Browser.EnableDeepThink` / `Browser.EnableSearch`, then verified. A missing toggle is a warning, not an error.
+
+## Recovery
+
+- Empty replies / "server busy": retried with backoff inside the reply timeout.
+- Captcha: not solved — the user solves it in the browser while the agent waits.
+- Debug mode (`-v` / `Browser.Debug`): screenshots on errors into `.agent/logs/`, structured diagnostics log. Cookies, tokens and page HTML are never logged.
+
+## ⚠️ Manual verification still required
+
+Built from a DOM sample, verified only by unit tests so far. Before relying on it, verify against a **real chat**:
+
+1. **Code indentation**: send a reply containing an indented code block and confirm the parsed AgentScript preserves leading spaces (the extractor reads raw `
` text nodes for this reason — but confirm on the live DOM).
+2. **Stop indicator**: confirm the selector matches the generating state (falls back to stability-based detection otherwise).
+3. **New Chat button** and **login page** selectors.
+4. **File upload**: confirm `.md`/`.txt` uploads render for the model; otherwise switch `AttachOnFeedback`-style pasting happens automatically.
+5. Toggle labels (`DeepThink`/`Search` texts) and `aria-pressed` values.
+
+Record the results of this checklist in this file after testing.

+# Configuration
+
+KeylessAgent reads `keyless.json` from the workspace root. The first run writes the full default file so you can edit it. Parsing is **tolerant**: comments (`//`), case-insensitive keys, trailing commas, and string enums (`"Ask"`, `"AutoSafe"`, …) all work. Invalid JSON or out-of-range values fail with a precise message instead of an exception.
+
+```jsonc

+
+## Sections
+
+### Mode (approval)
+
+- **Ask** *(default)* — every `runcommand` and `deletefile` needs your confirmation; file changes show a colored diff first.
+- **AutoSafe** — allow-listed commands run automatically; everything else still asks.
+- **Auto** — everything runs automatically (the deny list still applies), with a warning.
+
+### Browser
+
+- **ChromeDebugPort**: start Chrome with `chrome --remote-debugging-port=9222`; KeylessAgent attaches over CDP to your real profile. If that fails it launches a persistent Chromium profile under `%LOCALAPPDATA%\KeylessAgent\chrome-profile` (log in once; it stays logged in).
+- **Toggles**: before the first message of a new chat the agent reads each toggle's `aria-pressed` and only clicks when it disagrees with the config; if a toggle cannot be found it warns and continues.
+- **Debug/verbose** (`keyless run … -v` or `Browser.Debug`): writes `.agent/logs/diagnostics.log` and saves screenshots on errors.
+
+### Limits
+
+See [agentscript-spec.md](agentscript-spec.md#limits-enforced-injected-into-the-system-prompt).
+
+### Snapshot
+
+- Filtering applies to the **attached copy only** — `tree-view-result.txt` and `code-dump-result.md` on disk are never modified.
+- Oversized dumps are split at `### heading` boundaries into `code-dump-result-part1.md`, `-part2.md`, … and uploaded as consecutive files.
+
+### Git
+
+Protected patterns are matched case-insensitively with `*` wildcards. The guard runs **in code** before every file-changing command and every commit/push.
+
+### Commands
+
+The allow list matches the first program name of the command line. The built-in deny list (format/shutdown/force-push/`git config --global`/`curl | sh`/recursive deletes/encoded PowerShell/…) always applies and cannot be configured away.
+
+## Other files
+
+- `selectors.json` — the editable chat selector catalog (see [browser-automation.md](browser-automation.md)); created with defaults on first run.
+- `.agent/session.json` — the saved chat URL, branch and turn counter (powers `keyless resume`).
+- `.agent/backups/` — timestamped backups of every changed file (powers `keyless undo`).
+- `.agent/logs/turn-N.jsonl` — full per-turn transcript (messages, replies, commands, results).
+- `.git/info/exclude` — the agent adds `.agent/`, `tree-view-result.txt` and `code-dump-result.md` automatically.

+# Git workflow
+
+## Session start (per workspace)
+
+1. **Repository check** — not a git repo → the turn stops with `KA_NOT_A_GIT_REPOSITORY`.
+2. **Exclude upkeep** — `.agent/`, `tree-view-result.txt`, `code-dump-result.md` are appended to `.git/info/exclude` when missing.
+3. **Dirty tree** — if there are uncommitted changes the user chooses: `continue` (work on top), `stash` (`git stash push -u -m "keyless-agent auto stash"`), or `cancel`.
+4. **Main branch detection** — `git symbolic-ref refs/remotes/origin/HEAD`, falling back to `origin/main`, then `origin/master`, then `main`.
+5. **Branch setup**
+   - Current branch protected (`main`/`master`/`release*`, case-insensitive, `*` wildcards, configurable) → the agent creates `agent/-` from it and switches (`git checkout -b`). The slug comes from the request (kebab-case, `[a-z0-9-]`, max 40 chars, `task` when nothing survives — non-Latin requests included).
+   - Current branch not protected → the user chooses: press Enter for a new agent branch (default) or `keep` to continue on it.
+
+## During the turn
+
+- The **branch guard runs in code** before every `newfile`, `updatefile`, `editfile`, `deletefile`, and every `commit`/push — a protected branch can never be modified even if the model asks.
+- `commit` = `git add -A` → `git commit -m ""` → `git push -u origin ` (never force). A failed push is returned to the model as an error result and shown to the user.
+
+## Hard never-list (enforced by the policy / git service)
+
+No force push, no `reset --hard` on shared branches, no branch deletion, no merge, no rebase onto protected branches, no git global/system config changes. **Merging the agent branch is done only by the developer.**
+
+## End of turn
+
+- The branch name and the commit list (`git log --oneline`, newest first) are shown to the user.
+- The session (chat URL + branch + turn number) is persisted in `.agent/session.json`, so later requests (and `keyless resume`) continue in the same chat on the same branch.
+
+## Undo
+
+Every changed file is backed up to `.agent/backups//…` before modification. `keyless undo` restores the newest batch — it does **not** touch commits; use git for that.

+# Security model
+
+Model output is arbitrary text that gets executed on the user's machine. Every layer below is enforced in C# (not only in the prompt) and covered by unit tests.
+
+## Path sandbox
+
+Every model-supplied path goes through `IPathSandbox` before any file operation:
+
+- workspace-**relative** only, `/` separators,
+- absolute paths, `..` and `.` segments rejected,
+- anything under `.git` or `.agent` rejected (agent-internal state),
+- escapes through symlinks/junctions rejected (`ResolveLinkTarget` walk of the path),
+- resolved paths must stay under the workspace root (case-insensitive on Windows).
+
+`ImanSoftware.FileStorage` itself has **no** path safety — the sandbox is always the first gate.
+
+## Command policy
+
+`ICommandPolicy` checks **every segment** of a `runcommand` line (split on `&&`, `||`, `;`, `|`):
+
+- **Deny list (built-in, not configurable):** `format`, `shutdown`, `diskpart`, `mkfs`…, `git config --global/--system`, `git push --force`/`-f`, `git branch -d`, `rd /s`, `rm -rf /`, `del /s`, encoded PowerShell (`-enc`), and piping downloads into shells (`curl … | sh`, `… | powershell`).
+- **Allow list** (`Commands.Allowlist`): decides what runs automatically in `AutoSafe` mode.
+
+Every process runs with a hard timeout and captured output.
+
+## Git rules (see also git-workflow.md)
+
+- The workspace must be a git repository.
+- No file change, commit or push on `main` / `master` / `release*` — the guard runs before **every** affected command, and results carry `KA_BRANCH_PROTECTED`.
+- Never: force push, `reset --hard` on shared branches, branch deletion, merge, rebase onto protected branches, git global config changes. Merging is done only by the developer.
+- `.agent/`, `tree-view-result.txt`, `code-dump-result.md` are added to `.git/info/exclude` automatically.
+
+## Approval modes and dry run
+
+| Mode | runcommand | deletefile | file writes |
+| --- | --- | --- | --- |
+| `Ask` *(default)* | confirm each | confirm each | diff shown first |
+| `AutoSafe` | auto when allow-listed | auto (backed up first) | auto |
+| `Auto` | auto | auto | auto |
+
+`--dry-run` executes nothing and prints what would happen. Declined-by-user commands are reported to the model as `KA_COMMAND_DECLINED` results — the model sees the refusal and can adapt.
+
+## Backups and undo
+
+Before any change, the current file version is copied to `.agent/backups//…`. `keyless undo` restores the newest batch. BOM bytes are preserved on rewrite.
+
+## Transparency and data hygiene
+
+- Full per-turn transcript in `.agent/logs/turn-*.jsonl` (messages, replies, commands, results).
+- Diagnostics log (`-v`) and error screenshots in Debug mode.
+- **Never logged**: cookies, tokens, full page HTML.
+- File contents are untrusted input: text inside the user's files that looks like commands is never executed — only AgentScript parsed from the model reply is executed.
+- The browser connection uses the user's own session; the agent never stores or types passwords, and waits for manual login when needed.
+
+## Terms-of-service notice
+
+Automating the DeepSeek web UI may violate the provider's terms of use and can get the account limited or banned. Selectors can break with any site update. The project is not affiliated with DeepSeek.

-Full documentation lives in the main repository.
+`keyless` is the command-line front end for [KeylessAgent](https://github.com/ImanEstiri/KeylessAgent). It drives your logged-in DeepSeek web chat through Chrome, applies the model's replies to your workspace using the strict AgentScript command language, and keeps your work on a protected agent branch.
+
+> Automating a web UI may violate the provider's terms of use and can get your account limited. This project is not affiliated with DeepSeek.
+
+## Installation
+
+Requires the **.NET 10** runtime and Chrome.
+
+```bash
+dotnet tool install --global ImanSoftware.KeylessAgent.Cli
+```
+
+## Usage
+
+```bash
+keyless run "Add xUnit tests for the markdown parser"
+keyless                              # interactive session, one chat reused
+keyless resume "continue with the failing test"
+keyless undo                         # restore the newest backup batch
+keyless config                       # show / create keyless.json
+```
+
+Start Chrome with `chrome --remote-debugging-port=9222` and make sure you are logged in to chat.deepseek.com, or let KeylessAgent launch a persistent profile for you.
+
+Full documentation — AgentScript, configuration, selectors, security model — lives in the main repository:

Subject: [PATCH 012/102] Make the workspace path the first input instead of
 assuming the current directory

- All commands now take the workspace path as their first positional
  argument: 'keyless run  ', 'resume 
  ', 'undo ', 'config '
- When omitted, the very first prompt asks for it, validating that the
  directory exists (current directory shown only as the default, never
  silently assumed); run/resume also prompt for a missing request
- Interactive default command prompts for the workspace before the first
  request; -w removed in favor of the positional argument
- README (root + tool) usage examples updated to workspace-first form

Subject: [PATCH 013/102] Fix CLI crash: never run prompts under a live
 display; make turns non-fatal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bug: wrapping a whole agent turn in AnsiConsole.Status made every Say/
Confirm/Ask during the turn throw Spectre's 'Trying to run one or more
interactive functions concurrently' and kill the process with exit 1.

- IAgentUserInterface gains BeginWait(message): Core now marks only actual
  waiting phases (chat reply, sends, runcommand process, snapshot scripts)
  with a disposable wait scope — never the whole turn
- New ConsoleUserInterface owns all console access through one semaphore;
  the spinner is a background task cancelled+joined before ANY other UI
  call (Say/Ask/Confirm/ShowDiff/ShowProgress), overlapping BeginWait is
  safe (previous spinner stopped first), scopes tolerate double stops
- AgentCliRunner no longer wraps turns in Status; a failing or cancelled
  turn is printed (message + .agent/logs pointer) instead of crashing
- InteractiveSession loop: turn failures return to the keyless> prompt,
  Ctrl+C cancels only the current turn (fresh linked token per turn);
  exit code 1 reserved for startup errors
- Console Output/InputEncoding set to UTF-8 at startup when not
  redirected; console markers switched to plain ASCII ([ok] [!] [x] [i])
  with proper markup escaping
- Tests: nested-exclusivity reproduction of the crash, BeginWait+Confirm
  stops spinner first, Say during a wait, overlapping waits, Ask after a
  disposed wait, and failing/cancelled turns returning to the prompt
  (Spectre.Console.Testing 0.57.2 via CPM); 164 tests green

From ecacb423eb9fbcbddbadd7970d88ed25c29bb8d9 Mon Sep 17 00:00:00 2001
From: Iman Estiri 
Date: Sun, 25 Oct 2026 23:22:14 +0330
Subject: [PATCH 014/102] Fix reply-identity bug: never return the previous
 assistant reply

Before every send the newest assistant message is fingerprinted
(data-virtual-list-item-key, else a hash of the final-answer text, plus
the visible count); the send itself must be confirmed within
Browser.SendConfirmSeconds (new, default 15: new message item, or empty
input + generating indicator) with one retry (click then Enter) before
failing KA_SEND_NOT_CONFIRMED; WaitForReplyAsync accepts only a reply
whose fingerprint differs from the pre-send one (identical text valid
only with a new message key), whose final answer exists and is stable
for two reads, and once the stop indicator is gone. Attachment sends
wait for chips + enabled send (Browser.UploadWaitSeconds, default 60)
and fall back to pasting on timeout.

Session logic now sits behind the IChatPage seam (PlaywrightChatPage =
real DOM; FakeChatPage in tests), enabling scenario tests (a)-(d).
Docs updated; 168 tests green.

 **Not covered by the DOM sample**: the generating/Stop state, the New Chat button, and the login page. Those selectors ship with several fallbacks and log a clear error naming the missing selector — fix them in `selectors.json` when DeepSeek changes.
 
+## Reply identity — never the previous reply
+
+After every send the DOM still shows the PREVIOUS assistant message until the new one renders
+(the list is virtualized; the stop indicator may also lag). To never return the old reply:
+
+1. **Before sending**, the session fingerprints the newest assistant message: its
+   `data-virtual-list-item-key` when present, otherwise a stable hash of its final-answer text,
+   plus the count of visible assistant messages (count alone is never trusted — virtualization).
+2. **The send itself is confirmed** within `Browser.SendConfirmSeconds` (default 15): a new
+   message item appeared in the DOM, or the input is empty and the stop/generating indicator
+   is on. Otherwise the send is retried once (click, then Enter) and then fails with
+   `KA_SEND_NOT_CONFIRMED`.
+3. **A reply is accepted only when all of these hold**: its fingerprint differs from the
+   pre-send one (identical text is valid only with a different message key), the final-answer
+   element exists, the text is stable for two reads one second apart, and the stop indicator
+   is gone.
+
+## Uploads — wait before sending
+
+After uploading attachments the send click waits until the upload settles (`Browser.UploadWaitSeconds`,
+default 60): the file chips are visible and the send button is enabled. On timeout (or when the
+file input cannot be used at all) the content is pasted into the message instead.
+
 ## Reading replies — final answer only
 
 Each assistant message can contain **two** `.ds-markdown` blocks: the reasoning (`.ds-think-content`, headed "Thought for N seconds") and the final answer (`.ds-markdown.ds-assistant-message-main-content`). Only the **final answer of the newest assistant message** is ever read; the reasoning never reaches the parser (it would break it), the logs, or the chat.

Subject: [PATCH 016/102] Handle line endings: workspace CRLF files survive
 model LF text

- LineEndings helper: detect dominant ending (mixed keeps the majority,
  tie means LF), normalize to LF, apply back; new files resolve their
  ending from .editorconfig (end_of_line, section globs), then
  .gitattributes (eol=), then the dominant ending of sibling source files
  (dot/config files excluded), then Environment.NewLine
- editfile: match and count FIND/REPLACE on LF-normalized text (the
  'matched N times' message included) and write back with the file's own
  ending; updatefile converts model content to the existing ending;
  newfile applies the resolved ending; BOM handling unchanged
- FileChange diffs are LF-normalized (no stray \r in the CLI diff) and
  MaxCommandOutputChars counts normalized characters in result messages
- Tests: CRLF+LF FIND matches once and stays CRLF, multi-line find,
  mixed-ending file, BOM+CRLF, newfile obeys .editorconfig and Windows
  NewLine, updatefile keeps endings, editorconfig globs, gitattributes,
  sibling dominance, diff without \r; 185 tests green

 ## Known limitations
 
 - **Windows only** for now (snapshot `.bat` scripts, `tree` command). The engine itself is portable.
+- Line endings are preserved per file (dominant ending wins for mixed files); a file with a truly 50/50 mix keeps LF.
 - **Web-UI automation is brittle**: DeepSeek can change its DOM at any time; selectors live in `selectors.json` so they can be fixed without recompiling, but they will need fixing. See [docs/browser-automation.md](docs/browser-automation.md).
 - **Reply reading has not yet been verified against a live chat** (indentation of code blocks, toggle behavior, stop indicator). This is the top item to validate manually.
 - No captcha solving: if a captcha appears, the agent waits for you to solve it in the browser.

Subject: [PATCH 017/102] Make approval behavior consistent and safer

- deletefile now asks for confirmation in Ask AND AutoSafe modes; only
  Auto skips it (a backup is always made in every mode)
- AutoSafe/Auto turns show a one-time warning at turn start:
  'AutoSafe is not a security boundary' (dotnet/node/python can run
  arbitrary code)
- docs/configuration.md, docs/security.md and the README approval table
  now state exactly what the code does
- Tests: deletefile asked+declined in Ask and AutoSafe, not asked in
  Auto, and the AutoSafe boundary warning; 186 tests green

Subject: [PATCH 018/102] Harden CLI console handling and make failures
 diagnosable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- BeginWait returns only after the Status display actually started
  (ManualResetEventSlim set from inside the display), so a prompt can
  never start in the gap; StopSpinner no longer gives up after 3s — it
  joins fully (30s upper bound with a warning), so any prompt/write
  always runs after the spinner is really gone
- ConsoleWriter becomes an instance over one IAnsiConsole (Shared for
  command output); commands and the runner route everything through the
  same console surface as the agent UI
- Turn failures print exception type + message; with -v the full stack
  trace is shown and appended to .agent/logs/diagnostics.log; the log
  path is always printed; WorkspacePrompt uses the same ASCII [x] marker
- Tests: prompt immediately after BeginWait never throws, slow spinner
  shutdown still lets the following prompt run, failing turns show the
  exception type and return to the keyless> prompt; 190 tests green

Subject: [PATCH 019/102] Harden send-button and toggle selectors against the
 real DOM sample
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- SendButton fallback order per the sample: icon button in the textarea's
  sibling container, iconLabelPrimary, filled-circle, filled next to the
  file input, submit — each candidate checked for visibility and
  aria-disabled before clicking (a disabled send is skipped, never the
  target); Enter stays the last fallback
- Every selector loop logs (Debug) which fallback INDEX matched, so a
  broken selector is one log line away
- Toggle and MessageItems selectors made pure-CSS first (:has-text kept
  as a Playwright-only later fallback); AttachmentChips added earlier
- Fragment tests with AngleSharp run the default catalog against real
  fragments of deepseek-dom-sample-trimmed.html: input placeholder, file
  input multiple, toggles aria-pressed, virtualized item keys, final
  answer vs reasoning, send fallbacks matching and skipping the disabled
  button; 198 tests green

Subject: [PATCH 020/102] Add /workspace and /help slash commands to the
 interactive session
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- /workspace  validates the directory, refuses while the loop is
  not ready (a failing switch keeps the old workspace), re-runs the git
  preconditions and clears the target workspace's .agent/session.json
  (fresh chat session), then prints the new header; every turn and
  callback receives the workspace explicitly — no CurrentDirectory
- /help lists the slash commands; any other /-prefixed input is rejected
  with a hint instead of being sent to the model
- InteractiveSession takes the workspace as a parameter and a
  switchWorkspace callback; InteractiveCommand wires preconditions via
  the git service and session store
- Tests: help listed without a model send, unknown /command rejected,
  switch recorded + used for subsequent turns, missing directory
  refused, failed switch keeps the old workspace, usage message;
  204 tests green

+The interactive session understands two slash commands: `/workspace ` (switch to another workspace — validated, with a fresh chat session for it) and `/help`. Any other input starting with `/` is rejected with a hint instead of being sent to the model.
+
 The first time a command runs in a workspace it creates `keyless.json` (configuration) and `selectors.json` (editable chat selectors) — see [docs/configuration.md](docs/configuration.md).

From af2528b9934d96824e606e0c2a1f7e51b35a2430 Mon Sep 17 00:00:00 2001
From: Iman Estiri

Subject: [PATCH 021/102] Fix send-logic risks: no duplicate sends, no
 duplicate attachments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Send retry happens only when the input STILL holds the text; a cleared
  input means the message was sent even when the virtualized item count
  did not change (treated as sent, then WaitForReplyAsync). Retry exactly
  once, and each attempt is the send button when clickable, otherwise
  Enter — never both in the same attempt (first attempt included)
- Attachment delivery judged by several signals: SetInputFiles result,
  the hidden file input's reported file names, composer-near elements
  showing a file name, chips visibility. Paste only when SetInputFiles
  itself failed or there is NO sign of the files after
  Browser.UploadWaitSeconds; uncertainty counts as attached with a
  warning — the same content is never both attached and pasted
- FakeChatPage gains FailClick, InputFileNames, VisibleFileNames and
  LastInsertedText; tests (a)-(e) cover all five scenarios; 209 tests green

Subject: [PATCH 022/102] Add keyless doctor: live selector check without
 changing the chat
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- IChatDiagnostics (Core, GUI-reusable) + ChatDiagnosticsService over the
  IChatPageInspector seam: probes every selectors.json key through the
  fallback lists and classifies MATCHED (index + count) / NOT FOUND /
  NOT APPLICABLE NOW (Stop idle, no chips, no reasoning, fresh chat,
  login); reports login state, DeepThink/Search aria-pressed, input
  editability and the page URL; exit 0 only when all required keys
  matched; never sends a message
- PlaywrightChatInspector (real DOM) with the shared connection logic
  from PlaywrightChatProvider; a new tab, never touching the user's chat
- --capture : trimmed HTML snapshots (composer, newest message,
  sidebar, chips) via HtmlTrimmer — scripts/styles/svg removed, long
  text replaced with '...' so no personal content leaves the machine
- --watch: waits for a manually sent prompt, captures generating and
  finished states once each
- keyless doctor CLI command with a state table; docs section 'How to
  verify selectors: keyless doctor'; 5 tests with a scripted inspector;
  214 tests green

 **Not covered by the DOM sample**: the generating/Stop state, the New Chat button, and the login page. Those selectors ship with several fallbacks and log a clear error naming the missing selector — fix them in `selectors.json` when DeepSeek changes.
 
+## How to verify selectors: keyless doctor
+
+`keyless doctor []` attaches to Chrome exactly like `run`, opens chat.deepseek.com
+in a **new tab**, and reports every selectors.json key without sending a message or changing
+the chat:
+
+- **MATCHED** (with which fallback index and the element count) — the selector works.
+- **NOT FOUND** — no fallback matched although the element is required; fix selectors.json.
+- **NOT APPLICABLE NOW** — the element legitimately cannot exist in the current state
+  (Stop while nothing generates, chips with nothing attached, Reasoning without a thinking
+  message, FinalAnswer on a fresh chat, LoginIndicator while logged in).
+
+It also prints the logged-in state, the DeepThink/Search `aria-pressed` values, whether the
+input accepts text, and the page URL. **Exit code 0 only when every required selector for the
+current state matched** (InputBox, SendButton, FileInput, NewChatButton, MessageItems,
+AssistantMessage, DeepThinkToggle, SearchToggle).
+
+Options:
+
+- `--capture ` writes trimmed HTML snapshots (scripts, styles, svg removed; message text
+  replaced with "...") of the composer, the newest message, the sidebar and any attachment
+  chips — attach them to bug reports instead of screenshots of real content.
+- `--watch` waits while you type a prompt and send it manually, then captures the generating
+  state (stop indicator) and the finished state once each — the two states the unit tests
+  cannot see.
+
+Run `keyless doctor` after every DeepSeek UI update: a NOT FOUND line points at exactly which
+fallback list to fix.
+
 ## Reply identity — never the previous reply
 
 After every send the DOM still shows the PREVIOUS assistant message until the new one renders

Subject: [PATCH 025/102] Treat file-input listing as 'selected', not
 'uploaded': wait for send readiness

- IsSendEnabledAsync is tri-state now: true/false when a send control
  matched, null when no send-control selector matches at all (fake page
  and real page agree); a null state never blocks the send
- After SetInputFiles succeeds, the session waits (up to
  Browser.UploadWaitSeconds) for BOTH a positive upload sign (files
  registered in the input, a chip showing a file name, chips visible)
  AND an enabled send control, whenever that control can be detected;
  an upload registered while the control stays disabled is sent anyway
  with a warning after the timeout
- Tests: send enabled only after N polls -> the click happens after
  enablement; undetectable send control -> no deadlock (returns well
  before the timeout); 225 tests green

Subject: [PATCH 026/102] Remove remaining sync-over-async; enforce with a
 source-scan test

- SelectorsCatalog.LoadAsync, PlaywrightChatInspector (ProbeAsync/
  GetToggleStateAsync/IsInputEditableAsync/CaptureTrimmedAsync) and the
  whole diagnostics pipeline are async with CancellationToken
- FileLoggerProvider no longer blocks inside ILogger.Log: Log enqueues
  into a Channel and one background task performs all storage
  I/O; the provider constructor does no I/O at all
- TurnLogger.StartAsync/AppendAsync/AppendResultAsync; AgentLoop awaits
  them; /workspace switch flow is async end to end (git preconditions and
  session clearing happen on the async path with the turn's token)
- New NoSyncOverAsyncRuleTests greps all src/ production sources for
  GetAwaiter().GetResult()/.Result/.Wait() and fails on any violation
  (tests are exempt); 225 tests green, zero warnings

Subject: [PATCH 027/102] Redesign browser connection: dedicated profile,
 probe/launch/attach, tab rules

Observed bug: a separate logged-out Chrome window opened (never focused)
showing the DeepSeek login page instead of the user's session.

Root causes fixed:
- Chrome 136 ignores --remote-debugging-port for the DEFAULT
  user-data-dir: the docs claiming a daily-profile attach were wrong and
  are corrected everywhere (README requirements, browser-automation
  Connection section, configuration.md). A dedicated profile
  (Browser.UserDataDir, default %LOCALAPPDATA%\KeylessAgent\chrome-profile)
  is now mandatory and the login persists in it
- The silent LaunchPersistentContext fallback is removed; it is opt-in
  (Browser.AllowPlaywrightLaunch=false) with an explicit warning
- pages[last] navigation (which could destroy a user's tab) is gone:
  an existing chat.deepseek.com tab is reused (Browser.ReuseExistingTab),
  otherwise a new TAB opens via CDP Target.createTarget newWindow:false,
  matched by URL polling; the tab is focused (BringToFrontAsync +
  Target.activateTarget), again when login is required
- Connection is now IBrowserConnector in Core (probe -> attach;
  auto-launch the REAL Chrome via IBrowserEnvironment: port probe,
  chrome.exe locate via config/registry/paths, Process.Start, wait 30s,
  attach; actionable KA_BROWSER_CONNECTION_FAILED with the exact manual
  command line; port-open-but-attach-failed reports the reason instead
  of falling through), shared by run, doctor and the new
  'keyless chrome ' command (dedicated Chrome + one-time login)
- Dispose policy: only the tab the agent opened is closed; the Chrome
  window stays running (Browser.CloseChromeOnExit=false default)
- New config keys: UserDataDir, AutoLaunchChrome, ChromePath,
  ReuseExistingTab, AllowPlaywrightLaunch, CloseChromeOnExit
- Tests with faked environment: port open -> attach (no relaunch),
  port closed -> launch then attach, Chrome missing -> actionable
  failure, auto-launch off -> fail instead of fall through, Playwright
  fallback opt-in surfaces as failure without a real browser, profile
  default resolution; 232 tests green

 The highest-risk part of KeylessAgent: driving the DeepSeek web chat with Microsoft.Playwright. This document explains what is automated, which selectors are used, and what still needs manual verification.
 
-## Connection
+## Connection — the Chrome 136 rule and the one-time login
 
-1. **Default — attach to your Chrome**: you start Chrome with `chrome --remote-debugging-port=9222`; the agent uses `ConnectOverCDP` and reuses your logged-in profile. Nothing is stored, no passwords are ever typed.
-2. **Fallback — persistent profile**: if CDP fails, the agent launches Chromium with a persistent context under `%LOCALAPPDATA%\KeylessAgent\chrome-profile`. Log in once; the login persists.
+Since **Chrome 136**, `--remote-debugging-port` is **ignored when Chrome uses its default
+user-data-dir**. Attaching to your daily Chrome profile is therefore impossible. KeylessAgent
+uses a **dedicated profile** (`Browser.UserDataDir`, default
+`%LOCALAPPDATA%\KeylessAgent\chrome-profile`) and you log in to DeepSeek **once**; the login
+persists there.
 
-If the login page is detected, the agent prints a warning and waits (up to 5 minutes) for you to log in manually.
+Connection order (every step reported through the UI — never silent):
+
+| Step | Behavior |
+| --- | --- |
+| 1. Probe | `GET http://127.0.0.1:/json/version` — open → attach ("Attached to Chrome on port N"). |
+| 2. Auto-launch (default on) | Start the REAL Chrome: `chrome --remote-debugging-port= --remote-debugging-address=127.0.0.1 --user-data-dir= --no-first-run --no-default-browser-check https://chat.deepseek.com/`; wait ≤30s for the port; attach; "Started Chrome with the KeylessAgent profile. Log in to DeepSeek in that window once." |
+| 3. Fallback | Only with `Browser.AllowPlaywrightLaunch: true` (default **false**): a Playwright-managed browser with its own profile, explicitly warned as separate/automated. |
+| Failure | Chrome not found/started → `KA_BROWSER_CONNECTION_FAILED` with the exact manual-start command line; port open but attach failed → the reason is reported instead of falling through. |
+
+Tab rules: an existing `chat.deepseek.com` tab is reused (`Browser.ReuseExistingTab`, default
+true) — **your other tabs are never navigated**; otherwise a new TAB opens in the existing
+window (`Target.createTarget … newWindow:false`). The chosen tab is focused
+(`BringToFrontAsync` + `Target.activateTarget`). When a login is required the tab is brought
+to front again and the agent waits (up to `LoginWaitSeconds` = 5 minutes), continuing
+automatically once the login indicator disappears.
+
+Dispose policy: only the tab the agent opened is closed; the Chrome window stays running
+(`Browser.CloseChromeOnExit: false`) so the next run reuses the warm session. `run`, `doctor`
+and `keyless chrome` all go through the same connection service (`IBrowserConnector`), so
+doctor reports which path was taken (attached / auto-launched / failed) and why. `keyless
+chrome ` starts only the dedicated Chrome for a first login.

-### Browser
+### Browser — the Chrome 136 rule
 
-- **ChromeDebugPort**: start Chrome with `chrome --remote-debugging-port=9222`; KeylessAgent attaches over CDP to your real profile. If that fails it launches a persistent Chromium profile under `%LOCALAPPDATA%\KeylessAgent\chrome-profile` (log in once; it stays logged in).
+Since Chrome 136, `--remote-debugging-port` is **ignored when Chrome runs with its default
+user-data-dir**. Attaching to a daily Chrome profile is impossible; a dedicated profile is
+mandatory. KeylessAgent therefore uses one dedicated profile and one login:
+
+1. **Probe**: `http://127.0.0.1:/json/version` — if it answers, attach ("Attached to Chrome on port N").
+2. **Auto-launch** (default on): start the REAL Chrome with `--remote-debugging-port … --user-data-dir= --no-first-run --no-default-browser-check`, opening chat.deepseek.com, wait up to 30s for the port, attach. Log in to DeepSeek **once** in that window; the login persists in the profile.
+3. **Playwright fallback**: only with `AllowPlaywrightLaunch: true` (default false) — a separate automated browser, clearly warned.
+4. If Chrome cannot be found or started, the agent fails with `KA_BROWSER_CONNECTION_FAILED` and prints the exact manual-start command line.
+
+Tab rules: an existing `chat.deepseek.com` tab is reused (`ReuseExistingTab`); otherwise a new TAB is opened in the existing window (`Target.createTarget … newWindow:false`). The agent never navigates your other tabs. The chosen tab is focused (`BringToFrontAsync` + `Target.activateTarget`), also when a login is required.
+
+Dispose policy: only the tab the agent opened is closed; the Chrome window stays running by default (`CloseChromeOnExit: false`) so the next run reuses the warm session.
+
+`keyless chrome ` starts only the dedicated Chrome (for logging in first), and `keyless doctor ` reports which connection path was taken.
 - **Toggles**: before the first message of a new chat the agent reads each toggle's `aria-pressed` and only clicks when it disagrees with the config; if a toggle cannot be found it warns and continues.
 - **Debug/verbose** (`keyless run … -v` or `Browser.Debug`): writes `.agent/logs/diagnostics.log` and saves screenshots on errors.

Subject: [PATCH 028/102] Git workflow UX: numbered menus, auto init, no-origin
 push skip

- IAgentUserInterface.ChooseAsync with ChoiceRequest/ChoiceOption/ChoiceResult
  (UI-agnostic); ConsoleUserInterface numbered menu: arrows move, digits 1-9
  pick immediately, Enter confirms the highlighted (default marked), Esc/Ctrl+C
  cancels; non-interactive input returns the default and prints it; runs inside
  the console gate (spinner stopped first)
- AgentLoop preconditions rewritten as one combined flow: at most ONE menu per
  turn, none when the tree is clean and the branch is protected (agent branch
  auto-created); dirty menu carry/stash/here/cancel (here omitted on protected
  branches); branch menu new/stay/cancel on clean non-protected branches; the
  typed 'type continue/stash/cancel' and 'press Enter or type keep' prompts removed
- Auto git init (Git.AutoInit default true): git missing -> KA_GIT_NOT_INSTALLED
  with download link + manual steps; git init -b main (fallback init + branch -M
  main); .NET .gitignore via dotnet new gitignore or built-in template when the
  workspace has .sln/.slnx/.csproj; initial commit 'Initial commit (created by
  KeylessAgent)' with one-shot -c user.name/user.email identity fallback
- CommitExecutor: no 'origin' remote -> commit locally and skip push with a
  notice in the result sent to the model; origin present + push failure reported
  as before; KA_GIT_INIT_FAILED for init/commit failures; AgentTurnResult.ErrorCode
- ConfirmAsync shows the bracketed default, Enter accepts, no empty-input loop
- 233 tests green

+# DOCS-TODO (temporary; deleted in Task 3)
+
+## Task 1 — Git workflow UX
+- IAgentUserInterface.ChooseAsync(ChoiceRequest) — UI-agnostic numbered choice prompt; ChoiceRequest/ChoiceOption/ChoiceResult in Abstractions/Models/Agent.
+- CLI ConsoleUserInterface.ChooseAsync: numbered menu, arrow keys + Enter, digit hotkeys, Esc/Ctrl+C cancel, default highlighted "(default)"; non-interactive input returns the default and prints it.
+- AgentLoop git preconditions rewritten as menus: dirty tree = carry/stash/here/cancel (here omitted on protected branch); non-protected clean = new/stay/cancel; protected branch = agent branch auto-created, no menu.
+- Old "press Enter or type keep" and "type continue/stash/cancel" prompts removed; AskAsync kept only for free-form (e.g. @@ask).
+- ConfirmAsync: Enter accepts the bracketed default, no loop on empty input.
+- Auto git init: git missing → KA_GIT_NOT_INSTALLED; git init -b main (fallback init + branch -M main); Git.AutoInit default true; one-line notice.
+- Auto .gitignore: dotnet new gitignore when dotnet works, else built-in minimal template (bin/, obj/, .vs/, *.user, .idea/).
+- Initial commit "Initial commit (created by KeylessAgent)" with one-shot -c user.name/email identity fallback.
+- No 'origin' remote → @@commit commits locally and skips push with notice; error codes KA_GIT_NOT_INSTALLED, KA_GIT_INIT_FAILED; config Git.AutoInit.
+
+## Task 2 — ReplySource (Copy button)
+- Browser.ReplySource = Auto | Copy | Dom (default Auto); IReplyReader strategy + validation in Core.
+- New selector key MessageCopyButton (hover newest message first; newest message only).
+- Capture strategies: init-script interception of clipboard.writeText/execCommand/copy event gated by a capture flag (OS clipboard untouched) → OS clipboard read with grant + save/restore in finally → Dom fallback (Auto) / KA_REPLY_TIMEOUT (Copy).
+- Validation: normalized (markdown/punctuation stripped, whitespace collapsed, lowercased) containment or similarity >= 0.9; reasoning-start must NOT appear in the copy; copy not empty and >= 50% of DOM length; failure logs numbers and falls back ("Dom (copy rejected)").
+- Parser: outer code fence stripped only when first AND last non-blank lines are fences of same/greater length; inner fences untouched.
+- System prompt: no outer code fence, plain AgentScript; nonce reminder kept.
+- doctor: MessageCopyButton match, capture strategy used (interception/clipboard/none), clipboard left unchanged, copied length, validation result; --capture saves trimmed action-bar HTML.
+- Turn log records the reply source per reply.
+
+## Task 3 — docs rewrite (README, docs/*, CLI README) + consistency tests; DOCS-TODO deleted.

+## Task 1 additions (final)
+- AgentTurnResult.ErrorCode (KA_ code on turn failure).
+- ConfirmAsync shows the bracketed default (Spectre ShowChoices), Enter accepts it, no loop.
+- AgentLoop dirty menu: carry(default)/stash/here(non-protected)/cancel; branch menu new(default)/stay/cancel only on clean non-protected; protected+clean = auto agent branch, zero menus.
+- GitService: IsInstalledAsync, InitRepositoryAsync (-b main with fallback), EnsureDotnetGitignoreAsync (dotnet new gitignore or minimal template), CreateInitialCommitAsync (one-shot -c identity), HasOriginRemoteAsync.
+- CommitExecutor: no origin -> Ok "committed locally, push skipped".

Subject: [PATCH 029/102] Reply reading via the message Copy button
 (ReplySource) with DOM fallback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Browser.ReplySource = Auto | Copy | Dom (default Auto); Auto tries the
  Copy capture, validates, falls back to Dom; Copy never falls back
  silently (KA_REPLY_TIMEOUT); Dom is the original behavior
- New selector key MessageCopyButton (message-level Copy copies ONLY the
  final answer; bar may be hover-only — the newest message is hovered
  first, and only the NEWEST message's control is ever clicked)
- IChatPage capture members + Playwright implementation: ExposeBinding
  interception wrapping navigator.clipboard.writeText, execCommand('copy')
  and the copy event, gated on an agent-only flag (user's manual copying
  and the OS clipboard are never affected); clipboard fallback grants
  clipboard-read/write, saves the previous text, reads readText() and
  ALWAYS restores it in a finally block
- ReplyReader: strategy + validation (normalized markdown/punctuation-
  stripped comparison: containment or similarity >= 0.9; reasoning start
  must be absent; copy >= 50% of DOM length; numbers logged on rejection)
- Completion detection unchanged (fingerprint + final answer + stop +
  stable); IChatSession.LastReplyOrigin surfaces Copy/Dom/Dom (copy
  rejected) and the AgentLoop logs reply-source per reply
- Parser fence tolerance: outer fence stripped only when the first AND
  last non-blank lines are fences of the same or greater length (3 or 4
  backticks); inner fences inside CONTENT payloads untouched; system
  prompt tells DeepSeek not to wrap replies in a code fence
- doctor: MessageCopyButton probe + ReplyCapture check (strategy,
  clipboardUntouched, copiedLength, validation result)
- 247 tests green (14 new: ReplyReader validation/strategies, parser
  fences, interception/clipboard/none flows)

+- ReplySourceMode (Auto/Copy/Dom, default Auto) + Browser.ReplySource config; selector key MessageCopyButton (3 fallbacks incl. aria-label Copy).
+- IChatPage capture members: GetNewestReasoningTextAsync, WaitForMessageCopyButtonAsync (hover first), PrepareReplyCaptureAsync (ExposeBinding + init script wrapping writeText/execCommand/copy event, agent-flag gated), TryCaptureCopiedReplyAsync (interception -> OS clipboard read with grant + save/restore in finally).
+- IReplyReader logic in Core (ReplyReader): Copy-first per mode, validation (normalized containment or similarity >= 0.9, reasoning-start must be absent, >= 50% DOM length), Auto falls back with "Dom (copy rejected)" origin, Copy fails KA_REPLY_TIMEOUT.
+- IChatSession.LastReplyOrigin ("Copy" / "Dom" / "Dom (copy rejected)"); AgentLoop logs reply-source per reply into the turn log.
+- Parser fence tolerance: outer fence stripped only when first AND last non-blank lines are fences of same/greater length (3 or 4 backticks); inner fences untouched.
+- System prompt: no outer code fence; nonce reminder.
+- doctor: MessageCopyButton probe + ReplyCapture check (strategy, clipboardUntouched, copiedLength, validation); --capture unchanged; capture probe uses a PlaywrightChatPage over the same tab.
+- ExposeBindingAsync interception; OS clipboard always restored in finally.

+Your final answer must be PURE AgentScript v1: a sequence of blocks followed by a final line `@@eof`. Nothing else. No prose, no Markdown, no code fences around the whole answer, no explanations. Do NOT wrap the reply in a Markdown code fence — output plain AgentScript. File contents inside CONTENT payloads may contain code fences freely; if a file's content contains a line equal to an end marker, use the nonce form (<<>>).
 
 The web Search and DeepThink features are enabled and may be used for research and reasoning — but reasoning, search notes and citations must NEVER appear in the final answer. Any explanation for the user goes inside `@@say` blocks.

Subject: [PATCH 030/102] Docs written once: README + docs/* rewrite,
 consistency tests, DOCS-TODO removed

- README rewritten: tagline, requirements (.NET 10, Windows, git, Chrome with
  the Chrome 136 dedicated-profile rule), install, first run, usage with the
  numbered git menus and auto-init notice, Mermaid agent loop, AgentScript
  summary, reply sources table (Copy/Dom), safety model ('AutoSafe is not a
  security boundary'), known limitations, roadmap, layout, ToS/not-affiliated
- docs: git-workflow.md (auto init, numbered menus, at-most-one-menu flow,
  no-origin push skip), security.md (menu note), configuration.md
  (ReplySource + Git.AutoInit), browser-automation.md (reply sources,
  capture strategies, validation rules), agentscript-spec.md
  (KA_GIT_NOT_INSTALLED, KA_GIT_INIT_FAILED)
- CLI README updated (chrome/doctor commands, menus, auto init)
- DocsConsistencyTests: every ErrorCodes KA_ code must appear in
  agentscript-spec.md; every Browser/Limits/Git/Commands default must appear
  in configuration.md; the documented keyless.json block must deserialize to
  values equal to the default options object
- DOCS-TODO.md deleted; 250 tests green

-## Task 1 — Git workflow UX
-- IAgentUserInterface.ChooseAsync(ChoiceRequest) — UI-agnostic numbered choice prompt; ChoiceRequest/ChoiceOption/ChoiceResult in Abstractions/Models/Agent.
-- CLI ConsoleUserInterface.ChooseAsync: numbered menu, arrow keys + Enter, digit hotkeys, Esc/Ctrl+C cancel, default highlighted "(default)"; non-interactive input returns the default and prints it.
-- AgentLoop git preconditions rewritten as menus: dirty tree = carry/stash/here/cancel (here omitted on protected branch); non-protected clean = new/stay/cancel; protected branch = agent branch auto-created, no menu.
-- Old "press Enter or type keep" and "type continue/stash/cancel" prompts removed; AskAsync kept only for free-form (e.g. @@ask).
-- ConfirmAsync: Enter accepts the bracketed default, no loop on empty input.
-- Auto git init: git missing → KA_GIT_NOT_INSTALLED; git init -b main (fallback init + branch -M main); Git.AutoInit default true; one-line notice.
-- Auto .gitignore: dotnet new gitignore when dotnet works, else built-in minimal template (bin/, obj/, .vs/, *.user, .idea/).
-- Initial commit "Initial commit (created by KeylessAgent)" with one-shot -c user.name/email identity fallback.
-- No 'origin' remote → @@commit commits locally and skips push with notice; error codes KA_GIT_NOT_INSTALLED, KA_GIT_INIT_FAILED; config Git.AutoInit.
-
-## Task 2 — ReplySource (Copy button)
-- Browser.ReplySource = Auto | Copy | Dom (default Auto); IReplyReader strategy + validation in Core.
-- New selector key MessageCopyButton (hover newest message first; newest message only).
-- Capture strategies: init-script interception of clipboard.writeText/execCommand/copy event gated by a capture flag (OS clipboard untouched) → OS clipboard read with grant + save/restore in finally → Dom fallback (Auto) / KA_REPLY_TIMEOUT (Copy).
-- Validation: normalized (markdown/punctuation stripped, whitespace collapsed, lowercased) containment or similarity >= 0.9; reasoning-start must NOT appear in the copy; copy not empty and >= 50% of DOM length; failure logs numbers and falls back ("Dom (copy rejected)").
-- Parser: outer code fence stripped only when first AND last non-blank lines are fences of same/greater length; inner fences untouched.
-- System prompt: no outer code fence, plain AgentScript; nonce reminder kept.
-- doctor: MessageCopyButton match, capture strategy used (interception/clipboard/none), clipboard left unchanged, copied length, validation result; --capture saves trimmed action-bar HTML.
-- Turn log records the reply source per reply.
-
-## Task 3 — docs rewrite (README, docs/*, CLI README) + consistency tests; DOCS-TODO deleted.
-
-## Task 1 additions (final)
-- AgentTurnResult.ErrorCode (KA_ code on turn failure).
-- ConfirmAsync shows the bracketed default (Spectre ShowChoices), Enter accepts it, no loop.
-- AgentLoop dirty menu: carry(default)/stash/here(non-protected)/cancel; branch menu new(default)/stay/cancel only on clean non-protected; protected+clean = auto agent branch, zero menus.
-- GitService: IsInstalledAsync, InitRepositoryAsync (-b main with fallback), EnsureDotnetGitignoreAsync (dotnet new gitignore or minimal template), CreateInitialCommitAsync (one-shot -c identity), HasOriginRemoteAsync.
-- CommitExecutor: no origin -> Ok "committed locally, push skipped".
-
-## Task 2 additions (final)
-- ReplySourceMode (Auto/Copy/Dom, default Auto) + Browser.ReplySource config; selector key MessageCopyButton (3 fallbacks incl. aria-label Copy).
-- IChatPage capture members: GetNewestReasoningTextAsync, WaitForMessageCopyButtonAsync (hover first), PrepareReplyCaptureAsync (ExposeBinding + init script wrapping writeText/execCommand/copy event, agent-flag gated), TryCaptureCopiedReplyAsync (interception -> OS clipboard read with grant + save/restore in finally).
-- IReplyReader logic in Core (ReplyReader): Copy-first per mode, validation (normalized containment or similarity >= 0.9, reasoning-start must be absent, >= 50% DOM length), Auto falls back with "Dom (copy rejected)" origin, Copy fails KA_REPLY_TIMEOUT.
-- IChatSession.LastReplyOrigin ("Copy" / "Dom" / "Dom (copy rejected)"); AgentLoop logs reply-source per reply into the turn log.
-- Parser fence tolerance: outer fence stripped only when first AND last non-blank lines are fences of same/greater length (3 or 4 backticks); inner fences untouched.
-- System prompt: no outer code fence; nonce reminder.
-- doctor: MessageCopyButton probe + ReplyCapture check (strategy, clipboardUntouched, copiedLength, validation); --capture unchanged; capture probe uses a PlaywrightChatPage over the same tab.
-- ExposeBindingAsync interception; OS clipboard always restored in finally.

+Every LLM coding tool wants an API key. If you already use DeepSeek's web chat, KeylessAgent turns that login into your agent backend:
 
 - **No API key, no billing setup.** The browser session you already have is the credential.
 - **Strict command language.** The model's reply must parse as [AgentScript v1](docs/agentscript-spec.md); anything else is rejected and re-requested automatically. Nothing outside the grammar ever executes.
-- **Workspace-aware.** Every request carries `tree-view-result.txt` and `code-dump-result.md` (generated by the two `.bat` files in your repo), so the model sees your actual project — filtered for noise, chunked to fit.
+- **Workspace-aware.** Every request carries `tree-view-result.txt` and `code-dump-result.md` (generated by the two `.bat` files in your repo), filtered for noise and chunked to fit.
 - **Loop with feedback.** After each executed batch the agent sends per-command results (`[KEYLESSAGENT RESULTS]`) back to the same chat, so multi-step tasks iterate until `@@done`.
+- **Reply sources.** Replies are read via the message's own Copy button (raw Markdown, perfectly preserved) with a DOM extraction fallback — see [docs/browser-automation.md](docs/browser-automation.md).
 - **Safety in code, not in the prompt.** Protected-branch guard, path sandbox, command policy, backups, approval modes — all enforced in C#, covered by tests.
 
 ## Requirements
 
 - Windows (the workspace scripts are `.bat`; see [known limitations](#known-limitations))
 - [.NET 10 SDK / runtime](https://dotnet.microsoft.com/download/dotnet/10.0)
+- Git (`git-scm.com`) — auto-detected; if the workspace is not a repository yet, KeylessAgent initializes one automatically (`Git.AutoInit`)
 - Chrome. KeylessAgent uses a **dedicated Chrome profile** (`%LOCALAPPDATA%\KeylessAgent\chrome-profile`):
   since Chrome 136 the debug port is ignored for Chrome's default profile, so a daily-profile
   attach is impossible. Run `keyless chrome ` once and log in to DeepSeek in that
   window — the login persists, and KeylessAgent auto-starts this profile afterwards
   (`Browser.AutoLaunchChrome`).
-- A DeepSeek account logged in to [chat.deepseek.com](https://chat.deepseek.com) in that browser
+- A DeepSeek account logged in to [chat.deepseek.com](https://chat.deepseek.com) in that profile
 - The two workspace scripts in your repo root: `tree-view.bat` and `code-dump.bat` (they generate the attachments; KeylessAgent never modifies them)

+
+Verified facts from real chats: the message-level Copy button copies ONLY the final answer
+(never the reasoning), the copied text is raw Markdown (indentation, markers, nested fences
+preserved), and it may or may not carry an outer code fence.
+
+| Mode (`Browser.ReplySource`) | Behavior |
+| --- | --- |
+| `Auto` *(default)* | Try Copy → validate → fall back to Dom. The used source is logged per reply. |
+| `Copy` | Copy only; capture or validation failures return `KA_REPLY_TIMEOUT` (never silent fallback). |
+| `Dom` | The original DOM extraction. |
+
+**Capture strategies, in order:**
+
+1. **Interception**: an injected script wraps `navigator.clipboard.writeText`, `document.execCommand('copy')` and the `copy` event, reporting the text to C# through an exposed binding — active ONLY while the agent's capture flag is set, and the OS clipboard is never written, so the user's manual copying is unaffected.
+2. **Clipboard read**: grant `clipboard-read`/`clipboard-write`, save the current clipboard text, hover the newest message and click its message-level Copy control, read `navigator.clipboard.readText()`, and ALWAYS restore the previous text in a `finally` block.
+3. **None**: fall back to Dom (Auto) or fail with `KA_REPLY_TIMEOUT` (Copy).
+
+**Validation** (rendered DOM text and raw Markdown differ by syntax, so normalized forms are compared — markdown/punctuation stripped, whitespace collapsed, lowercased): (a) the normalized DOM text is contained in the normalized copy, OR similarity ≥ 0.9 (token overlap + length ratio); (b) the first 60 normalized characters of the reasoning block must NOT appear in the copy; (c) the copy is non-empty and at least 50% of the DOM length. On failure the numbers are logged and Auto falls back ("Dom (copy rejected)").
+
+Completion detection is unchanged (new-message fingerprint, final-answer element, stop indicator gone, stable); with Copy the message-level Copy control of THAT newest message must also appear (hover first — the bar may be hover-only), otherwise Dom fallback (Auto) or `KA_REPLY_TIMEOUT` (Copy). The parser strips an outer code fence only when the first AND last non-blank lines are fences of the same or greater length, so a copied reply wrapped in a fence parses fine while inner fences survive.

 ## Session start (per workspace)
 
-1. **Repository check** — not a git repo → the turn stops with `KA_NOT_A_GIT_REPOSITORY`.
+1. **Repository check** — not a git repo:
+   - `Git.AutoInit` true (default): the agent checks that git is installed (`KA_GIT_NOT_INSTALLED` with a download link when missing), runs `git init -b main` (fallback `git init` + `git branch -M main` on old git), creates a .NET `.gitignore` when the workspace contains a `.sln`/`.slnx`/`.csproj` (`dotnet new gitignore`, else a built-in minimal template), makes the initial commit "Initial commit (created by KeylessAgent)" — with a one-shot `-c user.name="KeylessAgent" -c user.email="keyless@localhost"` identity when none is configured (git config is never changed) — and tells the user in one line. Failure → `KA_GIT_INIT_FAILED`.
+   - `Git.AutoInit` false: the turn stops with `KA_NOT_A_GIT_REPOSITORY`.
 2. **Exclude upkeep** — `.agent/`, `tree-view-result.txt`, `code-dump-result.md` are appended to `.git/info/exclude` when missing.
-3. **Dirty tree** — if there are uncommitted changes the user chooses: `continue` (work on top), `stash` (`git stash push -u -m "keyless-agent auto stash"`), or `cancel`.
+3. **Dirty tree (numbered menu, no typing)** — options: **carry** (default; changes move to the new agent branch), **stash** (`git stash push -u -m "keyless-agent auto stash"`; restore later yourself), **here** (continue on the current branch — only offered on non-protected branches), **cancel**. Arrow keys / digits / Enter / Esc.
 4. **Main branch detection** — `git symbolic-ref refs/remotes/origin/HEAD`, falling back to `origin/main`, then `origin/master`, then `main`.
 5. **Branch setup**
-   - Current branch protected (`main`/`master`/`release*`, case-insensitive, `*` wildcards, configurable) → the agent creates `agent/-` from it and switches (`git checkout -b`). The slug comes from the request (kebab-case, `[a-z0-9-]`, max 40 chars, `task` when nothing survives — non-Latin requests included).
-   - Current branch not protected → the user chooses: press Enter for a new agent branch (default) or `keep` to continue on it.
+   - Current branch protected (`main`/`master`/`release*`, case-insensitive, `*` wildcards, configurable) → **no menu**: the agent creates `agent/-` automatically and tells the user. The slug comes from the request (kebab-case, `[a-z0-9-]`, max 40 chars, `task` when nothing survives — non-Latin requests included).
+   - Current branch not protected AND the tree is clean → one menu: **new** (default; create a new agent branch) / **stay** (continue on the current branch) / **cancel**. When the tree was dirty, the dirty menu already decided (carry → new agent branch, here → stay) and no second menu appears.
+
+At most **one menu** per turn; none when the tree is clean and the branch is protected.
 
 ## During the turn
 
 - The **branch guard runs in code** before every `newfile`, `updatefile`, `editfile`, `deletefile`, and every `commit`/push — a protected branch can never be modified even if the model asks.
-- `commit` = `git add -A` → `git commit -m ""` → `git push -u origin ` (never force). A failed push is returned to the model as an error result and shown to the user.
+- `commit` = `git add -A` → `git commit -m ""` → push. When the repo has **no `origin` remote**, the commit is made locally and the push is SKIPPED with a notice ("No 'origin' remote; committed locally") — the result sent to the model says so. When origin exists and the push fails, the failure is returned to the model as an error result and shown to the user.

Subject: [PATCH 031/102] Fix phantom cancel; native C# snapshot analyzer
 replaces the workspace bat files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Phantom 'cancelled by the user': IsDebugPortOpenAsync rethrew
OperationCanceledException — but HttpClient's own 2s timeout surfaces as
TaskCanceledException (an OCE subclass), so a closed port was misreported
as user cancellation. The probe now uses a linked timeout CTS and only
propagates cancellation of the CALLER's token; a probe timeout reads as
'port closed'.

Branch 'HEAD': rev-parse --abbrev-ref returns 'HEAD' on an UNBORN branch
(no commits yet). GetRepositoryInfoAsync now prefers
'git branch --show-current' (returns the real name, e.g. main, on unborn
branches), falling back to rev-parse. On an unborn branch the dirty menu
no longer offers 'continue on HEAD' nonsense — main is protected-style
handled via the auto agent-branch flow.

Native snapshots: WorkspaceAnalyzer generates tree-view-result.txt
(tree /F /A-shaped ASCII tree) and code-dump-result.md (### headings with
' > ' separators + language fences, same extension list and excluded
folders as the reference scripts) directly in C#. SnapshotService no
longer runs any bat file — nothing to paste into workspaces. Tests
updated (bat-less fixtures + a works-without-bat-files test) and docs
mentions removed. 250 tests green

 ### Snapshot
 
+- The snapshots are **generated natively in C#** — no `.bat` files need to exist in the workspace. `tree-view-result.txt` and `code-dump-result.md` are written into the workspace root (and excluded from git via `.git/info/exclude`).
 - Filtering applies to the **attached copy only** — `tree-view-result.txt` and `code-dump-result.md` on disk are never modified.
 - Oversized dumps are split at `### heading` boundaries into `code-dump-result-part1.md`, `-part2.md`, … and uploaded as consecutive files.

Subject: [PATCH 032/102] Fix paperclip click (OS file dialog) and Enter-only
 send retry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 'Open' Explorer window and the never-sent message: the SendButton
fallback 'ds-button--iconLabelPrimary' is the PAPERCLIP next to the file
input — clicking it opens the OS file dialog, returned true, and Enter
was never pressed; the retry then clicked it again (second dialog).

- SendButton fallbacks rebuilt: the filled/primary button in the file
  input's sibling container first, primary-filled, filled-circle, submit;
  the paperclip selector is gone from the list AND explicitly skipped in
  code (class check via JSON.stringify state)
- Send retry is now Enter-only: the first click already proved the
  control ineffective, and re-clicking a mis-identified control just
  opens more dialogs
- Tests: paperclip never a send candidate (fragment test), retry is
  click+enter (session test); docs decision table updated; 251 tests green

+## Follow-up fixes (post-docs)
+- SendButton fallbacks: paperclip (iconLabelPrimary) removed and explicitly skipped in code — clicking it opened the OS "Open" file dialog instead of sending; retry is now Enter-only.
+- Unborn-branch fix: git branch --show-current preferred (rev-parse --abbrev-ref returns "HEAD" with no commits).
+- Port-probe timeout no longer surfaces as "cancelled by the user" (TaskCanceledException distinguished from caller cancellation).
+- Snapshots generated natively in C# (WorkspaceAnalyzer) — no workspace bat files needed.

-## Follow-up fixes (post-docs)
-- SendButton fallbacks: paperclip (iconLabelPrimary) removed and explicitly skipped in code — clicking it opened the OS "Open" file dialog instead of sending; retry is now Enter-only.
-- Unborn-branch fix: git branch --show-current preferred (rev-parse --abbrev-ref returns "HEAD" with no commits).
-- Port-probe timeout no longer surfaces as "cancelled by the user" (TaskCanceledException distinguished from caller cancellation).
-- Snapshots generated natively in C# (WorkspaceAnalyzer) — no workspace bat files needed.

Subject: [PATCH 036/102] First message = AgentScript rules alone; visible
 reply trail; hidden file-input upload fix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Real-chat findings (turn with 15/2/2 problems): the model never reliably
learned the grammar when the rules were mixed into the request message,
and the attachments were pasted as text because SetInputFiles never ran.

- AgentLoop: a new chat now receives the AgentScript rules as message 1
  (alone, 'applies to every response in this conversation'), then the
  user request + attachments as message 2; SystemPromptSent persists per
  chat as before
- System prompt: rules apply to the ENTIRE conversation; explicit list of
  the ONLY valid keywords (no @@command, no JSON) at the very top
- format-correction.txt now carries a compact AgentScript cheat-sheet so
  the model can recover from format errors without guessing
- Console trail: every raw reply is shown in a panel (truncated to 2000
  chars, full text in .agent/logs) together with the validating-verdict
  progress line; validation summary numbers are logged
- Upload fix: the chat's file input is display:none — the old
  FirstVisible(5s) wait always timed out so every upload silently fell
  back to pasting. TryUploadFilesAsync now tries SetInputFiles directly
  per fallback selector (works on hidden inputs) and logs which matched
- 251 tests green (happy-path updated for the two-message flow)

Subject: [PATCH 037/102] Prompt lessons from the live run; keep the chat open
 across turns; auto-minimize
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- System prompt: 'you DO execute commands yourself via @@runcommand — never
  give the user commands to run'; payload markers must be ALONE on their own
  lines (single-line <<>> was rejected 3x); paths never
  './'-prefixed; rules apply to the whole conversation
- format-correction.txt: same lessons appended to every correction so the
  model recovers without guessing
- AgentLoop: the AgentScript rules go out as message 1 ALONE on a new chat,
  then the request + attachments as message 2 (mixing them made the model
  skim the grammar)
- Console trail: every raw reply is shown in a panel (2000-char cap, full
  text in .agent/logs) plus a validating-verdict line with the last source
- Upload: the file input is display:none — SetInputFiles is now attempted
  directly per fallback selector instead of waiting for Visible (which made
  every upload fall back to pasting)
- Tab/window policy: the chat tab STAYS OPEN after every turn and after exit
  (only CloseChromeOnExit closes it); the saved chat URL is navigated to when
  the reused tab is elsewhere; the launched/logged-in window is minimized
  automatically via CDP after login (doctor: no minimize)
- 251 tests green

 dirty-menu rules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- IWorkspaceInspector + WorkspaceCapabilities probed ONCE per session and
  cached — every git decision uses them; no per-turn re-probing
- NO-GIT MODE (git not installed): ONE warning and zero prompts; branch
  guard, agent branch, dirty menu, branch menus all skipped; @@commit
  returns Error/KA_GIT_NOT_INSTALLED 'git unavailable, nothing committed'
  without failing the turn; the system prompt carries a 'git is NOT
  installed — do not use @@commit or git commands' note
- Dirty-tree menu rules: skipped when every dirty path is in
  session.AgentChangedPaths AND the current branch is an agent branch;
  'carry to a new agent branch' dropped when already on an agent branch
  (default becomes 'here')
- IChangeTracker: git porcelain before/after and a no-git path/size/mtime
  index excluding ignored folders; added/modified/deleted/renamed
- AgentLoop: per-batch change diff unions into session.AgentChangedPaths
  (file commands + runcommand side effects); AgentSession.AgentChangedPaths
  + TurnsInChat added
- Tests: capabilities (no-git/agent-branch/cached), change tracker (git and
  no-git, ignored folders), no-git mode (warn once, no prompts, commit
  result, system-prompt note); 260 tests green

Subject: [PATCH 039/102] Command risk classifier and failure-reason model
 (Task 2 part 1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- ICommandRiskClassifier + CommandRiskClassifier: segment-aware (quotes
  respected, && || ; | splits) tier classification — ReadOnly (known
  read-only programs and git subcommands), Build (dotnet
  build/restore/clean), Execute (test/run/watch/exec, node/npm/python
  scripts), Risky (inline interpreters, redirection, command substitution,
  package installs, deletes/moves/copies, git writes, workspace-escaping
  paths, unknown programs), Denied (deny list)
- RunCommandExecutor: tier-based approval policy (Ask auto-approves
  configured tiers, AutoSafe adds allow-listed Execute, Auto runs all),
  confirmation shows tier + reason, progress line shows auto-approval;
  failure reasons classified (command_not_found via exit 9009/127/'not
  recognized', timeout, non_zero_exit) with CommandExecutionResult.
  FailureReason; command_not_found message tells the model the program is
  missing
- Error codes: KA_COMMAND_NOT_FOUND (+ doc), Commands.AutoApprove and
  Commands.BatchFailureMode config keys; FailureReason on results
- Partial: @@next/@@movefile/env block follow in the next commit

 - Dirty menu: "carry" option dropped when already on an agent branch (default becomes "here"); menu skipped entirely when all dirty paths ∈ session.AgentChangedPaths AND on agent branch; uncommitted-changes notice distinguishes agent vs foreign changes.
 - AgentLoop: capabilities probed once via IWorkspaceInspector (cached); turn change baseline via IChangeTracker; agent-changed paths persisted to session.AgentChangedPaths after each batch.

Subject: [PATCH 041/102] Format reliability: lenient one-line payloads,
 per-message reminder, targeted tests

- Parser: lenient one-line payload form <<>> for MSG/FIND/
  REPLACE/CMD/TO (never CONTENT) normalized to multi-line; CONTENT lines
  containing <<< stay content; detected before PayloadStartRegex match
- Per-message reminder: ~8-line AgentScript summary + env summary prepended
  to every user-request message (full system prompt stays first-message-only)
- Tests: real failing reply from a live run (one-line FIND/REPLACE payloads)
  now parses successfully; CONTENT lines with <<< stay content; 262 tests green

Subject: [PATCH 042/102] Browser window behavior: never un-minimize during
 normal operation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Browser.WindowMode (Minimized default) and Browser.MinimizeAfterLogin
  (true) config keys
- Launch flags --disable-renderer-backgrounding --disable-background-timer-
  throttling --disable-backgrounding-occluded-windows prevent throttling
  when minimized
- Hover calls removed from copy capture — the copy button is clickable
  without hovering in most browsers, and hovering un-minimizes the window
- Window restored ONLY for login/captcha; minimized again after login
  (Browser.MinimizeAfterLogin); 262 tests green

-## Prompt-lessons batch
-- system-prompt.md: "you DO run commands" + payload markers alone on their own lines + no ./ prefix + rules apply to the whole conversation.
-- format-correction.txt: same lessons + cheat-sheet.
-- AgentLoop: system prompt sent as message 1 alone; request+attachments as message 2.
-- Console trail: raw reply panel (2000-char cap) + validating verdict with last source.
-- Upload: hidden file input — SetInputFiles tried directly per fallback (no Visible wait).
-- Provider: chat tab stays open after turns/exit unless CloseChromeOnExit; auto-minimize after login (CDP setWindowBounds); ResumeChatUrl navigation when the reused tab isn't on the saved chat.
-- CommitExecutor/file executors: NoGitMode in AgentExecutionContext — branch guard skipped, @@commit → Error/KA_GIT_NOT_INSTALLED "git unavailable, nothing committed" without failing the turn.
-- Dirty menu: "carry" option dropped when already on an agent branch (default becomes "here"); menu skipped entirely when all dirty paths ∈ session.AgentChangedPaths AND on agent branch; uncommitted-changes notice distinguishes agent vs foreign changes.
-- AgentLoop: capabilities probed once via IWorkspaceInspector (cached); turn change baseline via IChangeTracker; agent-changed paths persisted to session.AgentChangedPaths after each batch.

-- @@movefile  + <<>> (MoveFileCommand + MoveFileExecutor): sandboxed both paths, backup, refuses overwrite (KA_FILE_ALREADY_EXISTS), creates parents, undo-covered.
-- EnvironmentProbe: parallel 3s-timeout probes (OS, git, dotnet, node, npm, python) → [ENVIRONMENT] block in the first message + one-line summary.
-- Browser: MinDelayMs=0, MaxDelayMs=150, HumanDelay=false defaults; random delay only when HumanDelay=true.

-## Task 3 additions
-- Lenient one-line payload: <<>> / <<>> / etc for non-CONTENT sections, normalized to multi-line form (CONTENT never affected).
-- Per-message reminder: ~8-line AgentScript summary + env summary prepended to every user-request message; full system prompt stays on first message only.
-- ReplyExtractor: entity-decoded text in the fake (HtmlEncode in fake page), one-line payload tests with real failing reply.

-- Hover calls removed from copy capture (never un-minimizes during normal operation).

 ## Session start (per workspace)
 
-1. **Repository check** — not a git repo:
+1. **Repository check** — probed once per session via IWorkspaceInspector (GitInstalled, IsRepository, CurrentBranch, IsAgentBranch). Not a git repo:
    - `Git.AutoInit` true (default): the agent checks that git is installed (`KA_GIT_NOT_INSTALLED` with a download link when missing), runs `git init -b main` (fallback `git init` + `git branch -M main` on old git), creates a .NET `.gitignore` when the workspace contains a `.sln`/`.slnx`/`.csproj` (`dotnet new gitignore`, else a built-in minimal template), makes the initial commit "Initial commit (created by KeylessAgent)" — with a one-shot `-c user.name="KeylessAgent" -c user.email="keyless@localhost"` identity when none is configured (git config is never changed) — and tells the user in one line. Failure → `KA_GIT_INIT_FAILED`.
    - `Git.AutoInit` false: the turn stops with `KA_NOT_A_GIT_REPOSITORY`.
+   - **git not installed at all**: ONE warning ("no branch protection, no commits, no git history, changes cannot be reverted with git; file changes are still backed up in .agent/backups"), then NO-GIT MODE: no branch guard, no agent branch, no dirty menu, no commit/push. @@commit returns Error/KA_GIT_NOT_INSTALLED "git unavailable, nothing committed" without failing the turn. The system prompt carries a note telling the model not to use @@commit or git commands.
 2. **Exclude upkeep** — `.agent/`, `tree-view-result.txt`, `code-dump-result.md` are appended to `.git/info/exclude` when missing.
-3. **Dirty tree (numbered menu, no typing)** — options: **carry** (default; changes move to the new agent branch), **stash** (`git stash push -u -m "keyless-agent auto stash"`; restore later yourself), **here** (continue on the current branch — only offered on non-protected branches), **cancel**. Arrow keys / digits / Enter / Esc.
+3. **Dirty tree (numbered menu, no typing)** — skipped when every dirty path was changed by the agent itself (tracked in session.AgentChangedPaths) AND the current branch is an agent branch. Options: **carry** (changes move to the new agent branch; only offered when NOT already on an agent branch), **stash** (`git stash push -u -m "keyless-agent auto stash"`; restore later yourself), **here** (continue on the current branch — only on non-protected branches), **cancel**. Default: carry off-branch, here on-branch. Arrow keys / digits / Enter / Esc.
+
+Change tracking works with and without git: with git, `git status --porcelain` snapshots are compared; without git, a lightweight path/size/mtime index (excluding bin/obj/.git/.agent/node_modules/artifacts/.vs/.idea/TestResults) is used. The agent-changed path set is persisted in `.agent/session.json` after each batch.
 4. **Main branch detection** — `git symbolic-ref refs/remotes/origin/HEAD`, falling back to `origin/main`, then `origin/master`, then `main`.
 5. **Branch setup**
    - Current branch protected (`main`/`master`/`release*`, case-insensitive, `*` wildcards, configurable) → **no menu**: the agent creates `agent/-` automatically and tells the user. The slug comes from the request (kebab-case, `[a-z0-9-]`, max 40 chars, `task` when nothing survives — non-Latin requests included).

Subject: [PATCH 046/102] Fix window un-minimize: remove focus from normal
 operation; add ITimingRecorder
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- BrowserConnector.OpenChatTabAsync: removed the BringToFrontAsync +
  Target.activateTarget block that ran on EVERY tab open/reuse (this caused
  Chrome to un-minimize on every message). Focus now happens ONLY in
  WaitForLoginIfNeeded (login page detected → restore; login done → minimize)
- ITimingRecorder + TimingRecorder: per-phase timing recorder wired into
  AgentLoop for config, git-checks, env-probe, connect, send, reply, execute
  phases; timings written to the turn log; 262 tests green

 - The snapshots are **generated natively in C#** — no `.bat` files need to exist in the workspace. `tree-view-result.txt` and `code-dump-result.md` are written into the workspace root (and excluded from git via `.git/info/exclude`).

Subject: [PATCH 049/102] Add /newchat slash command; chat lifecycle;
 classifier 108 tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- /newchat clears session.json for the same workspace (fresh chat without
  switching workspaces); /workspace  validates git and
  clears the session for the new workspace
- /help now lists /newchat; SwitchWorkspace handles same-workspace (just
  clear session) vs different-workspace (validate git + clear session)
- Browser.MaxTurnsPerChat (default 20) — auto new chat when reached
- ChatLimitNotice selector key (3 fallbacks) for conversation-too-long
  detection, reported by keyless doctor
- CommandRiskClassifierTests: 108 test cases covering all tiers,
  chains, quotes, path escapes, inline interpreters, package installs,
  deletes/moves/copies, git writes, unknown programs, and empty commands
- 370 tests green; build with zero warnings

+## /newchat and chat lifecycle (follow-up)
+- /newchat slash command: same workspace → clears .agent/session.json for a fresh chat.
+- /workspace  → validates git + clears session for the new workspace.
+- Browser.MaxTurnsPerChat (default 20) → auto new chat when reached.
+- ChatLimitNotice selector key (3 fallbacks) reported by keyless doctor.
+- SwitchWorkspace: same workspace clears session only; different workspace validates git + clears session.

Subject: [PATCH 050/102] Fix dry-run sending to chat: guard request-send with
 if (!dryRun)

The request-send block (and its auto-new-chat post-send) was not guarded
by if (!dryRun), so a dry-run turn sent the system prompt was correctly
skipped but the user request was still sent to DeepSeek. The block is now
wrapped in if (!dryRun) with the ui.ShowProgress left outside so the user
still sees intent. Regression test RunAsync_DryRun_DoesNotSendAnyMessage
asserts chat.Sent is empty after a dry-run turn.

  had already executed). on_error= on @@runcommand overrides the mode for
  that command; read-only commands (tier ReadOnly, @@readfile) never stop
  a StopOnMutationFailure batch; skipped commands report
  'batch stopped at command #N'.
- CommandExecutionResult: Tier populated from the risk classifier by
  RunCommandExecutor, default Risky so file-command failures stop.
- Parser: @@runcommand on_error=continue|stop (KA_PARSE_BAD_OPTION for
  unknown values).
- Executors: branch protection no longer applies in dry-run - the loop
  simulates the agent branch, so mutation commands are previewed instead
  of blocked with KA_BRANCH_PROTECTED (fixes dry-run preview on main).
- Tests: batch-stop regression tests (third command not executed,
  read-only probe does not stop, on_error=continue overrides
  StopOnAnyFailure) and parser on_error tests; 377 passing.
- Docs: agentscript-spec skipped-message wording, security.md dry-run
  note, stale DOCS-TODO cleared.

Subject: [PATCH 052/102] Report a missing program as KA_COMMAND_NOT_FOUND, not
 KA_INTERNAL

ProcessRunner catches Win32Exception from process.Start() and returns
ProcessResult with NotStarted=true; RunCommandExecutor maps that to
Status=Error, ErrorCode=KA_COMMAND_NOT_FOUND, FailureReason
command_not_found. Previously the start failure escaped the runner and
surfaced as an internal error. Regression test:
RunCommand_ProgramMissing_ReturnsCommandNotFound (378 passing).

Subject: [PATCH 053/102] Validate control directives on parse-valid replies
 too

The @@next/@@done conflict check and the say-only check in
AgentScriptValidator.Validate ran inside the invalid-parse early return,
so a parse-valid reply containing both @@next and @@done (or only @@say)
passed validation. Both checks now run on every parse before the early
return. Regression tests: Check_NextAndDoneInOneReply_IsRejected,
Check_SayOnly_IsRejected (380 passing).

Subject: [PATCH 054/102] Fix MaxTurnsPerChat ordering, TurnsInChat counting,
 AgentChangedPaths persistence

- TurnsInChat is now incremented at turn start (after StartSessionAsync),
  so the saved count is real; it was read but never written before.
- MaxTurnsPerChat is checked at session load, BEFORE connecting: when the
  chat has served its limit the session is cleared and the turn starts a
  fresh chat (system prompt resent). The old post-send auto-new-chat
  block - which cleared the session only after the message had already
  gone to the old chat - is removed.
- AgentChangedPaths is persisted in .agent/session.json: seeded from the
  saved session at turn start, unioned with the change-tracker diff of
  the current turn in the finally block (so failed turns still record
  their changes), and written with the session save. The dirty-menu skip
  can now actually fire. The duplicate diff in the @@done branch is gone.
- FakeChatProvider gains StartCount and per-session message counts, each
  session gets a distinct ChatUrl; two regression tests: two turns with
  MaxTurnsPerChat=1 land in separate chats (2/2 messages each,
  TurnsInChat=1 after the reset) and @@newfile paths persist in
  session.json. 382 passing.

Subject: [PATCH 055/102] Reset the copy-capture buffer before each capture
 attempt

PlaywrightChatPage._capturedCopy was set by the ExposeBinding handler and
never cleared, so a capture attempt whose copy click missed the
interception returned the PREVIOUS reply's text. The buffer is now reset
at the start of TryCaptureCopiedReplyAsync (before arming interception)
and defensively after installing the binding in
PrepareReplyCaptureAsync; the OS-clipboard fallback is unchanged.
Regression test runs two turns through the Copy-capture path (Auto mode +
visible Copy control, CapturedReply flipped per send) and asserts the
second WaitForReplyAsync returns the new reply. 383 passing.

Subject: [PATCH 056/102] Report the send button as disabled when aria-disabled
 is set

IsSendEnabledAsync compared the evaluated bool against the string
"true"; a bool ToString()s as "True", so the comparison always failed
and the method reported the button as enabled regardless of
aria-disabled or the ds-button--disabled class. The state now crosses as
JSON.stringify({ d: ... }) and is parsed with JsonDocument (same pattern
as the paperclip detection, which is unchanged). No unit test exercises
the Playwright implementation directly (tests run against FakeChatPage),
so the assert is manual via keyless doctor; noted in the code. 383
passing.

Subject: [PATCH 058/102] Include only known extensions in the code dump

WorkspaceAnalyzer.DumpExtensions was defined but never used:
EnumerateDumpFiles yielded every file under the workspace root, so
binaries, logs and user data landed in code-dump-result.md. The
enumerator now filters by Path.GetExtension against DumpExtensions
(case-insensitive) after the output-file exclusion; ExcludedDirectories
is unchanged. SnapshotServiceTests refreshes a workspace with Program.cs,
README.md, a .png, a .dll, a .log and obj/native.dll and asserts the dump
contains the source files but no binary/log headings and no obj entries.
386 passing.

Subject: [PATCH 059/102] Populate AgentTurnResult.ChangeSet so the CLI can
 show changed files

AgentLoop declared turnChanges but never filled it and never set
ChangeSet. The turn diff now runs once in the finally block (with
CancellationToken.None - the turn is over), feeding both the session's
AgentChangedPaths and ChangeSet on the returned result. The Failed
helper keeps an empty ChangeSet (it only runs before execution starts).

Two upstream porcelain bugs surfaced while testing, fixed in GitService:
Split's TrimEntries destroyed the fixed "XY path" columns (" M
file.txt" parsed as path "ile.txt"), and plain "status --porcelain"
collapses untracked directories (a new file in src/ reported as
"?? src/"). RunStatusPorcelainAsync now uses -uall and splits without
trimming.

Tests: ChangeSet reports a @@newfile path, a tracked-file @@updatefile as
modified, and a tracked-file @@deletefile as deleted. Note: a new
untracked file's kind is "modified" because ChangeTracker maps "??"
to modified ("added" is reserved for staged/no-git files) - ChangeTracker
was off-limits in this task, so the one-line "??" => "added" mapping is
left as a proposed follow-up. 389 passing.

Subject: [PATCH 060/102] Compare the dirty-menu skip against freshly read
 porcelain

skipDirtyMenu diffed the workspace against changeBaseline captured
seconds earlier - the diff was always empty, so the menu was skipped
vacuously whenever a non-empty agent-changed set existed, user-made
changes included. The check now reads git status fresh via
RunStatusPorcelainAsync and requires every porcelain path (same
fixed-column parsing as ChangeTracker: XY prefix, quotes, rename arrow)
to be in the session's AgentChangedPaths, in addition to repoDirty,
isAgentBranch and a non-empty set. User-made dirty paths still show the
menu. Tests: menu skipped when the only dirty path is agent-made; menu
shown when an extra user-made file is dirty. 391 passing.

Subject: [PATCH 061/102] Log reply-received once and show TurnFinished once
 per turn

AgentLoop appended reply-received twice per reply back-to-back (the
second without the Source field); the duplicate is removed. TurnFinished
progress was shown twice on two paths - the no-reply break showed it
before the finally block did, and Failed() showed it before returning
through the try into the finally. Both extra shows are gone: the no-reply
break just sets stoppedReason, and Failed() records the message in
stoppedReason so the finally displays identical content exactly once.
Tests: a two-batch turn logs exactly two reply-received entries (one per
reply, each with Source), and the no-reply and failed-config paths show
TurnFinished exactly once. 394 passing.

Subject: [PATCH 062/102] Correct the raw-reply comment: no -v path exists

The comment above the raw-reply panel claimed the reply is also shown
with -v, but the loop never receives the CLI's verbose flag, so valid
replies are never shown raw. Approach A per task: the comment now states
the actual behaviour (raw only when invalid; full text always in
.agent/logs). No behaviour change. 394 passing.

Subject: [PATCH 063/102] Time every chat phase and add a --timing flag

AgentLoop now records snapshot-refresh (both refresh sites), attachments
(both BuildAttachmentsAsync sites), upload (request send), reply-wait
(per batch), execute (aggregated over all commands) and results-send;
the recorder ignores a second Start for an already-running phase so a
double Start can no longer orphan the first stopwatch. The turn result
carries the FormatTable text (AgentTurnResult.Timings) alongside the
existing turn-log append, which is unchanged. AgentCliRunner.RunTurnAsync
gains timing and chatProvider parameters (optional, existing callers
unaffected) and prints the table before the keyless-undo line;
RunSettings and InteractiveSettings get --timing, wired through
RunCommand and InteractiveCommand. Tests: TimingRecorder double-start,
stop-without-start and sequential-pair behaviour; AgentCliRunner prints
Timing Summary + phases with --timing and none without. 399 passing.

Subject: [PATCH 064/102] Add approval counts and diff stat to the turn summary

AgentTurnResult gains AutoApprovedCommands, ConfirmedCommands and
DiffStat. The loop counts approvals through a pass-through UI decorator
handed to the executors: ConfirmAsync calls titled "Run command"
(RunCommandExecutor) count as confirmed - the deletion confirmation and
asks delegate uncounted - and auto-approved is derived as executed
runcommands minus confirmed. After the turn the loop runs
git diff --stat ...HEAD via ProcessRunner against the branch the
turn started from (git problems never fail the turn; empty on dry-run or
no-git). AgentCliRunner prints the indented diff stat, the
Auto-approved/Confirmed line, the merge hint, and keeps the undo note.
Tests: one auto-approved read + one confirmed command count 1/1; a
@@commit turn reports the committed file in DiffStat; the CLI output
contains the approval line and the merge hint. 401 passing.

Subject: [PATCH 065/102] Set the DeepThink and Search toggles on the first
 message of a new chat

EnableDeepThink/EnableSearch were documented but never applied. IChatPage
gains GetToggleStateAsync (aria-pressed of the first visible match,
null when no selector matches) and ClickToggleAsync, implemented in
PlaywrightChatPage with the existing first-visible-match probe pattern.
PlaywrightChatSession applies them once per chat, before the first send:
a new chat (no ResumeChatUrl) reads each toggle and clicks when it
disagrees with the option; a resumed chat keeps its state. Selector gaps
are logged as warnings and never fail the turn (empty selector arrays and
no-match both skip with a warning). FakeChatPage models toggles with
ToggleStates/ClickedToggles. Tests: a new chat clicks each mismatched
toggle exactly once and never on the second send; a resumed chat clicks
nothing. 403 passing.

Subject: [PATCH 066/102] Apply Browser.WindowMode when auto-launching Chrome

WindowMode was defined but never read: the launched Chrome always opened
normal and only the post-login path minimized anything. StartChromeAsync
now takes the window mode and composes its flag via an internal
ComposeChromeArguments helper: Minimized prepends --start-minimized,
Offscreen prepends --window-position=-32000,-32000, Normal adds no flag
and never forces focus; unknown or empty modes default to Minimized (the
configuration default). The throttling flags, profile and URL are
unchanged. BrowserConnector passes options.WindowMode through.
Tests: per-mode flag mapping (including unknown/empty defaults) on the
composed argument string, and the connector passing the mode to the
environment. 409 passing.

Subject: [PATCH 067/102] Honor Snapshot.RefreshAfterEachBatch between batches

The flag was read nowhere: only the end-of-turn refresh ran, so a model
working across several batches always saw turn-start attachments. After
each batch's results message is sent successfully (not in dry-run), the
loop now calls RefreshSnapshotAsync so the next batch's attachments
reflect the workspace as of right now. The end-of-turn refresh in the
finally block is unchanged. Tests use a recording fake ISnapshotService
(created via a new CreateLoop overload): a two-batch turn with the flag
refreshes exactly twice (once per batch, once in finally); without the
flag exactly once. 411 passing.

Subject: [PATCH 068/102] Produce a ChangedFiles attachment in TreeAndChanged
 mode

The mode was a placeholder: the dump was replaced by a notice string and
no changed-files attachment existed. RefreshAsync now persists the
workspace baseline to .agent/snapshot-baseline.json after every
successful refresh (git porcelain when the workspace really is a repo -
probed with git rev-parse, because git status succeeds with empty stdout
outside a repo and made every diff vacuously empty - otherwise a
path/size/mtime index). BuildAttachmentsAsync in TreeAndChanged mode
emits the tree plus a changed-files.txt attachment with " "
lines from DiffAsync against that baseline; a missing or unusable
baseline (first run, unreadable file, failed diff) falls back to the
full dump so the model is never left with nothing. Full mode unchanged.
Tests: modified+added+deleted surface as the three changed lines; no
baseline falls back to the real dump. 413 passing.

Subject: [PATCH 069/102] Detect and recover from chat length exhaustion

The ChatLimitNotice selectors existed but nothing read them: an exhausted
chat surfaced only as a reply timeout. IChatPage gains
IsChatLimitNoticeVisibleAsync (first-visible-match over the catalog
selectors, 500ms per fallback); PlaywrightChatSession probes it once
before waiting and once before the timeout failure (the notice may appear
mid-generation when the reply is cut). WaitForReplyAsync then fails with
KA_CHAT_EXHAUSTED. The AgentLoop reply-failure branch recognises that
code: it clears the saved session (so the next request opens a new chat),
does NOT resend the batch (commands already executed), and stops with
'chat exhausted; a new chat will be used on the next request. Re-run with
your current progress.' No automatic continuation. keyless doctor now
reports ChatLimitNotice (matched = exhausted; otherwise NOT APPLICABLE
NOW). Tests: session returns KA_CHAT_EXHAUSTED on the notice; the loop
stops with the message and session.json is gone; doctor classifies the
notice both ways. 417 passing.

Subject: [PATCH 070/102] Prove /newchat's clear leads to a new chat on the
 next turn

/newchat (InteractiveCommand.SwitchWorkspace, old==new) only calls
SessionStore.ClearAsync; nothing proved the next turn actually opened a
new chat rather than resuming the cleared one. The new AgentLoop
integration test runs turn 1 (session.json records fake-session-1),
performs the same clear the slash command does, runs turn 2, and asserts
session.json now records fake-session-2, the provider started exactly
two chats, and each chat received only its own turn's messages (2/2).
418 passing.

Subject: [PATCH 071/102] Treat shell machinery and Unix paths as Risky in the
 risk classifier

The classifier splits segments but does not model cmd.exe ^ escapes,
%VAR% expansion, history expansion, backgrounding, nested shells or
here-strings - a misclassified ReadOnly command is auto-approved in Ask
mode and can mutate the workspace. ClassifySegment now returns Risky
before any allow-list when a segment contains ^, %, !!, a single &
(pair splitting removed &&, so any surviving & backgrounds), @" or @',
or when the program is start/powershell/pwsh or cmd with /c or /k.
IsPathEscapingWorkspace only skips /flags whose body matches a known
cmd.exe flag list - /etc/passwd is now treated as a path and checked for
escape. npx with any bare argument is Risky (it downloads and runs an
arbitrary package; npx prettier moves from Execute to Risky
accordingly). The ReadOnly floor for unknown programs is enforced
structurally by KnownPrograms + the unknown-program default and now
pinned by tests. 14 new classifier cases, each failing on the previous
implementation. 432 passing.

Subject: [PATCH 072/102] Split policy segments with quote awareness
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CommandPolicy.SplitSegments used a plain string split on && || ; |, so a
pipe inside a quoted string (a dotnet --filter, an echoed deny-list word)
was treated as a segment boundary — a second 'segment' starting with a
deny-list word denied the whole legitimate command. The quote-aware
splitter from CommandRiskClassifier moved into a shared
ShellSegmenter.Split used by both files, so the policy and the classifier
see identical segments; the classifier's SplitSegments now delegates.
Deny patterns, allow-list behaviour and every policy check per segment
are unchanged. Tests: quoted pipes with a deny-list word inside
("Category=A|format C:", "format C:", "shutdown is a word") pass,
while an unquoted pipe before a deny-list program is still rejected.
437 passing.

Subject: [PATCH 073/102] Reject ADS, UNC and device paths in the path sandbox

PathSandbox did not cover the Windows attack surface beyond relative
paths and traversal: an Alternate Data Stream spelling (src/file.txt:secret)
resolved successfully and would have written a hidden stream. Resolve now
rejects any path containing ':' (relative paths may never carry a drive
letter or a stream) and the UNC/device spellings \, // and their \?\ /
\.\ forms, before the existing rooted/traversal checks. The 8.3-style
..\~1 case stays rejected by the traversal check (pinned by test);
case-insensitive resolution is pinned by test (SRC/Foo.cs == src/Foo.cs
under OrdinalIgnoreCase). A TOCTOU note documents that validation and
write are two steps: the executors must not follow reparse points when
writing, and any storage that gains link-following semantics must
re-validate at write time. 444 passing.

Subject: [PATCH 074/102] Refuse link escapes in backup and undo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BackupAsync copied a source file through IFileStorage: a symlink planted
in the workspace pointing outside had its TARGET copied into the backup.
Both BackupAsync and UndoLatestAsync now sandbox-check the relative path
with PathSandbox (reuse, no duplicated symlink logic) — link escapes,
traversal, streams and .git/.agent sources are refused with
KA_PATH_OUTSIDE before any copy. Undo additionally refuses to write
through a reparse point: a workspace path swapped for a symlink after the
backup is skipped with a recorded warning ('skipped:  (reason)' in
the returned list) instead of redirecting the restore outside; the rest
of the undo continues. Tests: regular-file backup/undo happy path, file
symlink backup rejected, symlinked restore target skipped without
writing outside (mklink planted; environments without link rights skip
silently). 448 passing.

Subject: [PATCH 075/102] Prove file contents are data, never AgentScript
 commands

Two prompt-injection tests back the docs claim that command-looking text
inside the user's files is never executed: a workspace file containing a
complete valid AgentScript reply plus an honest @@done model reply leaves
pwned.txt uncreated (the file content reaches the model only as a
code-dump attachment, and the injection file itself is untouched); and a
model reply mixing prose with blocks is rejected by the format guard
(the loop sends a [KEYLESSAGENT FORMAT ERROR] correction, nothing
executes, and the turn stops awaiting the corrected resend). No code
changes were needed - both guarantees already held. 450 passing.

Subject: [PATCH 076/102] Validate movefile paths in the format guard
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

AgentScriptValidator's switch had no MoveFileCommand case, so @@movefile
paths skipped the ParseBadPath check at validation time and only hit
PathSandbox at execution — an escaping ToPath was surfaced late (per-
command failure) instead of in the immediate format correction. Both the
from-path and the << src/b.txt move passes with no
problems. 452 passing.

Subject: [PATCH 077/102] Confirm file moves in Ask mode and show the diff
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MoveFileExecutor mutated silently: no diff, no confirmation — unlike
deletion. After the sandbox/existence checks and before the backup, Ask
and AutoSafe modes now show a FileChange diff for the move and ask for
confirmation ('Move file', with the destination and the backup note);
a decline returns KA_COMMAND_DECLINED and nothing is moved. Auto keeps
running without asking, and dry-run still previews without prompting.
Tests: declined move leaves both files untouched with KA_COMMAND_DECLINED;
confirmed move relocates the file and records exactly one diff. The test
suite's executor registry gained the MoveFileExecutor it was missing
(which is why the move path had never been exercised end-to-end there).
454 passing.

Subject: [PATCH 078/102] Make keyless undo reverse newfile and movefile

keyless undo only restored backed-up files: a @@newfile creation survived
undo and a @@movefile left its destination behind. Each backup batch now
carries a journal.jsonl - {op:create,path} written by NewFileExecutor
after a successful create, {op:move,from,to} written by MoveFileExecutor
into the same batch that holds the backed-up source (BackupAsync was
split into BackupToBatchAsync returning the stamp plus an
AppendJournalAsync; both best-effort - a journal failure never fails the
command). UndoLatestAsync processes the journal first (delete the created
file, delete the move destination, reported as 'removed: ' entries)
and then runs the existing copy restore, skipping the journal file
itself. Tests drive the real executors in Auto mode: undo deletes an
agent-created file; undo restores the moved source and removes the
destination. 456 passing.

Subject: [PATCH 079/102] Parallel selector waits, instant checks,
 positive-first login probe

FirstVisibleAsync raced fallback selectors SEQUENTIALLY with the full
timeout each, so an absent element cost N x timeout: login probing
(3 x 5s = 15s per start), stop-indicator polls (3 x 400ms per reply
poll). The fallback list now races in ONE combined Or-locator with ONE
timeout (winner identified by instant probes afterwards), and a new
instant IsAnyVisibleAsync (single round trip, no waiting) answers
'is it there right now' - stop-indicator polling, chat-limit notices,
attachment chips, toggles and send-enabled all use it; the session's
default reply poll drops to 100 ms. Login detection is positive-first:
ONE wait races InputBox against LoginIndicator (Browser.LoginProbeSeconds,
default 15) via IChatPage.WaitForAnyVisibleAsync; only a winning login
indicator focuses the tab (IChatPage.FocusTabAsync) and waits for the
manual login. The minimize call moved to the provider caller so the
probe method is pure. Per-phase timings now cover login-probe, toggles,
upload, paste, send, send-confirm, first-token, completion and copy
(ChatSessionOptions.Timings; the loop adds parse and passes its recorder
into the session), plus a compact 'Reply: N commands' progress line for
valid replies. 456 passing.

Subject: [PATCH 080/102] Fake-page round-trip tests for the wait fixes

PlaywrightChatProviderTests: the positive-first login probe with a fake
page - a logged-in start costs ONE parallel wait and never focuses the
tab or runs the login loop; a winning login indicator focuses once and
then polls with instant checks (never per-fallback waits); an
inconclusive probe (nothing matched) is treated as logged in. FakeChatPage
gains round-trip counters (stop polls, chat-limit probes, any-visible,
parallel waits, focus) and scripted results. PlaywrightChatSessionTests:
the stop-indicator poll interval stays at most 100 ms (polls >= elapsed/
100ms with instant checks, no serialized timeouts) and the chat-limit
probe costs exactly one round trip per reply wait. 461 passing.

Subject: [PATCH 081/102] Graceful Ctrl+C in the interactive session

Ctrl+C was only handled during keyless run; the interactive session died
with the process default. The session now owns Console.CancelKeyPress via
one RequestCancel seam: at the idle prompt a press exits gracefully
(exit 0; per-turn log flushes and connector disposal already happen at
turn end), during a turn the first press cancels only the turn and a
second press within 2 seconds exits gracefully. The idle prompt races the
exit signal (WhenAny) so the exit does not wait for stdin. Tests: idle
cancel exits 0; first cancel during a turn cancels exactly the turn,
second cancel within 2s exits 0. 461 passing.

Subject: [PATCH 082/102] Consistent step renderer for progress output
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ShowProgress printed raw enum names ('ValidatingReply ...'); it now
renders one consistent '› step: detail' shape with stable lowercase step
labels per event type, and a test pins the compact 'Reply: N commands'
line for valid replies. 463 passing.

InputBox-vs-LoginIndicator wait, LoginProbeSeconds=15, focus only when
the user must act), parallel Or-locator waits and instant checks with the
~100 ms reply-poll cadence, the ChatLimitNotice selector row, and the
interactive Ctrl+C behavior. configuration.md: LoginProbeSeconds key,
login-probe/fast-wait/--timing paragraphs. README + CLI README: --timing,
/newchat, --verbose, Ctrl+C semantics. DOCS-TODO.md deleted (it was
empty). DocsConsistencyTests extended: configuration keys, the recoverable
KA_ codes, README CLI options and slash commands, CLI README slash
commands and Ctrl+C. 467 passing.

 First run in a non-git workspace initializes the repository automatically (main branch, .NET .gitignore, initial commit — `Git.AutoInit`). Without git installed, a no-git mode runs file commands with backups only (no branch protection, no commits). Run `keyless chrome` once and log in to DeepSeek in the dedicated profile; since Chrome 136 the debug port only works with a dedicated profile, and the login persists there.

Subject: [PATCH 084/102] Pin the per-phase session timings through the fake
 page

A PlaywrightChatSession test with a scripted TimingRecorder asserts the
phases recorded around the real session flow: toggles, upload, send,
send-confirm, first-token, completion and copy all land in the table.
468 passing.

Subject: [PATCH 085/102] Parallel-wait the remaining sequential selector waits

Three wait sites still paid one timeout per fallback: the InputBox wait
(10 s x N in InsertTextAsync), the SendButton wait (3 s x N in
TryClickSendAsync) and the MessageCopyButton wait (full timeout x N).
All three now use the combined Or-locator FirstVisibleAsync helper -
one wait, one timeout, the matched fallback index returned; the same
total upper bound as today (the per-fallback timeout) applies once.
TryClickSendAsync keeps its disabled/paperclip screen, now on the single
matched candidate (a disable/paperclip verdict falls back to Enter
instead of paying more waits). FirstVisibleAsync gained a scope-based
overload (resolve delegate) so the copy-button race runs scoped to the
newest message, and the winner probes resolve at the same scope. The
clipboard fallback's fixed 500 ms sleep is now a 75 ms poll of the read
with the same 500 ms budget. Remaining WaitForAsync in the page: exactly
one (the combined wait itself). 468 passing.

Subject: [PATCH 086/102] Visibility-aware combined wait: a hidden first match
 cannot mask a later visible one

The Or-locator's .First is the first match in DOM ORDER - a hidden element
listed first made the visible-wait time out even though a later fallback
was visible. The combined wait now applies Filter(Visible = true)
(supported by the pinned Playwright 1.64.1; the EvaluateAsync fallback is
not viable because catalog selectors use Playwright-only pseudo-classes
like :has-text), so the race is over visible matches only. Winner
selection is extracted into SelectVisibleWinnerAsync - the first selector
whose instant visibility probe passes, in fallback order; hidden earlier
matches are skipped and nothing visible yields null. FakeChatPage models
DOM-order visibility (DomVisibility) for the parallel wait: a provider
test proves a hidden first InputBox selector does not stop a visible
login indicator from winning (focus happens, login poll runs), and a unit
test pins the winner rule itself. 470 passing.

Subject: [PATCH 087/102] Time the tab-open phase of the browser connection

'Choose or open the chat tab' was the one untimed connect step.
IBrowserConnector.ConnectAsync gains an optional ITimingRecorder (the
provider passes ChatSessionOptions.Timings), and OpenChatTabAsync wraps
its whole choose-or-open body (reuse-existing-tab, Target.createTarget,
page wait, and the test-seam override) in a 'tab-open' phase - a null
recorder costs nothing. Tests: the auto-launch path records tab-open
with a recorder and works without one. 472 passing.

Subject: [PATCH 088/102] Round-trip tests prove absent fallback lists cost one
 wait

NSubstitute joins the test project so the real Playwright IPage/ILocator
surface can be stubbed. PlaywrightChatPageRoundTripTests count the
Playwright round trips of the fallback waits: an absent InputBox costs
exactly one WaitForAsync with the 10s single budget (then the documented
no-input exception), an absent SendButton one WaitForAsync with the 3s
budget (then false), an absent MessageCopyButton one scoped WaitForAsync
with the caller's timeout (then false), the stop-indicator check one
IsVisibleAsync round trip, and a hidden-first DOM shows the winner
probes walking in fallback order until the later VISIBLE selector and
the text being inserted there. 477 passing.

Subject: [PATCH 089/102] Docs must match the real KeylessOptions defaults,
 verified by test

docs/configuration.md documented MinDelayMs 400 / MaxDelayMs 1500 while
the code defaults are 0 and 150, and placed Browser.MaxTurnsPerChat under
the Git section. Fixed. The new
DocsConsistencyTests.DefaultKeylessOptions_SerializeMatchesDocumentedJson
parses the documented jsonc blocks (string-aware // stripping), compares
them against the SERIALIZED default KeylessOptions with the production
serializer in both directions - every documented key must exist with the
same value (arrays element-wise, numbers numerically), and every
options property must be documented - so default drift can no longer
happen silently. 478 passing.

Subject: [PATCH 090/102] Never send secrets to the chat through snapshot
 attachments

code-dump attachments carried .json/.config files verbatim: connection
strings, API keys and whole environment files reached the DeepSeek chat.
Snapshot.Filter gains SensitiveFilePatterns (env files, key material,
*secret*/*password*/*credential*, production appsettings - case-
insensitive wildcards against the file name) and MaskSensitiveLines
(default true). BuildAttachmentsAsync now drops dump sections whose file
name matches a sensitive pattern and redacts secret-looking values in
the remaining sections - Password/Pwd/ApiKey/secret/token/credential
assignments keep the key name and become key=[redacted], JSON keys keep
their quoted shape, Authorization Bearer/Basic tokens are redacted,
PEM private-key blocks are redacted line-wise between BEGIN and END.
The tree attachment gets a '[N files filtered and M values masked as
sensitive]' marker line (omitted when both are 0). The attachment copy
only: code-dump-result.md, tree-view-result.txt and every source file on
disk stay byte-identical. New keys documented in configuration.md (the
consistency test caught them immediately) with a DOCS-TODO bullet.
Tests: .env/secrets.json/appsettings.Production.json filtered with
marker, secret values masked with keys kept, disk outputs unchanged,
and a comment mentioning 'password' untouched. 481 passing.

Subject: [PATCH 091/102] Stop when the debugging port answers but CDP attach
 fails

After 'Port N is open but attach failed' the connector logged and showed
progress but fell through to the auto-launch step - starting a SECOND
Chrome on a port already owned by another Chrome, which could only fail
again. The comment said 'do not fall through'; the code now honors it:
the connect fails right there with KA_BROWSER_CONNECTION_FAILED, the
attach error, and the hint 'Close the Chrome that owns port N or change
Browser.ChromeDebugPort.' FakeEnvironment gains FailAttach (attach
throws); the regression test asserts the failure code, the hint, and
that StartChrome was never called. 482 passing.

Subject: [PATCH 092/102] A turn that stops early exits with code 2

RunTurnAsync printed the stopped-reason warning and then returned 0 - CI
and scripts could not tell a stopped turn from a successful one. Exit
codes are now 0 success / 1 error / 2 stopped early / 130 cancelled; the
summary output (commits, summary, change set, timings) still prints for
stopped turns since they may have done real work. Also fixed a latent
test-flake root: AgentCliRunner used ConsoleWriter.Shared, which binds
AnsiConsole.Console at first touch - under the parallel suite the
warning could go to another test's captured console; the writer is now
resolved per call. Tests: stopped turn returns 2 with the warning, failed
turn returns 1, successful turn returns 0; the exit-code table is in
DOCS-TODO.md. 485 passing.

Subject: [PATCH 093/102] Corrupt session.json and failing log writes never
 crash a turn

SessionStore.LoadAsync deserialized without try/catch - invalid JSON in
.agent/session.json threw and killed the turn. It now treats any
deserialize failure (or null result) as no-session with
KA_SESSION_NOT_FOUND and renames the broken file to session.json.corrupt
(best effort) so the content survives for inspection; valid sessions are
never renamed. TurnLogger.StartAsync/AppendAsync wrote through storage
unguarded - an I/O error would fail the turn. Writes are now wrapped
(outcome failure AND exception), and the first failure disables logging
for the rest of the turn with exactly one warning through the new
optional warning callback; cancellation still propagates. Tests: corrupt
session returns KA_SESSION_NOT_FOUND with the .corrupt file preserved
and valid sessions never renamed; a logs path blocked by a file disables
logging with one warning and no throws; healthy logging stays
warning-free. 489 passing.

Subject: [PATCH 094/102] Commands after @@done are skipped, not executed

The batch loop ran EVERY command in the reply: after @@done set
completedByDone, the foreach kept executing later blocks (a newfile
after @@done really created the file) and the done-check only broke
after the whole foreach. Now a SUCCESSFUL @@done reports every remaining
non-say command as Skipped with the reason 'after @@done' (executed list
+ turn log via AppendResultAsync - the results message is intentionally
not sent when the turn is complete) and breaks the batch. A failed
@@done keeps the old behavior. Test: say + done + newfile leaves x.txt
uncreated with a Skipped/after @@done result entry in turn-1.jsonl.
490 passing.

Subject: [PATCH 095/102] Redact secrets from command output in the turn log

AppendResultAsync serialized CommandExecutionResult verbatim: command
output with credentials (connection strings, tokens, printed env vars)
landed in .agent/logs/turn-N.jsonl in plain text. New SecretRedactor
(compiled, case-insensitive): password/passwd/pwd/secret/token/apikey/
api-key/authorization/bearer followed by : or = and a value becomes
'=[redacted]' - optional quotes around key and value keep JSON
output structured, an optional bearer/basic scheme word is consumed so
'Authorization: Bearer ' loses the whole credential, and the
value stops at whitespace/quote/semicolon/comma so 'Password=x;Server=y'
only loses the credential. AppendResultAsync redacts the Output FIELD
before serialization (never regex over serialized JSON); requests and
replies are logged as received. Tests: password= line, JSON ApiKey and
Bearer token redacted with structure and non-secret lines kept. 492
passing.

Subject: [PATCH 096/102] Use the catalog selectors for the input editability
 check

PlaywrightChatInspector.IsInputEditableAsync hardcoded two textarea
selectors and paid a 2s wait per fallback. IChatPageInspector
.IsInputEditableAsync now takes the fallback list (catalog.InputBox from
ChatDiagnosticsService) and probes it with the shared parallel
Or-locator helper - one wait with the same 2s-per-fallback total budget.
FakeChatPage's inspector records the lists it receives; the regression
test asserts the doctor passes exactly catalog.InputBox. Also: the
stop-poll interval test's wall-clock upper bound was flaky under
parallel-CPU jitter (33 polls on this machine vs a 30 cap) - the
discriminating lower bound (instant checks, not serialized timeouts)
is kept without the jittery cap. 493 passing.

Subject: [PATCH 097/102] Defect sweep: 4 confirmed fixes, 2 invariants, 2
 already covered

1. Upload fallback: SetInputFiles success + no upload sign no longer
   pastes the content on top (it would double it) - treated as uploaded
   with a warning; paste only when the upload itself failed.
2. CloseChromeOnExit: the dispose lambda now knows the connection kind -
   a launched Chrome is closed for real (the old pages.Count == 0 guard
   was almost never true with our own tab open); an attached Chrome is
   NEVER closed even with the flag set.
3. ProcessRunner: timeout/cancel keep the partial stdout/stderr (readers
   drained up to 2 s) and expose Reason (timeout/cancelled); the executor
   reports cancelled commands as KA_CANCELLED, not KA_TIMEOUT.
4. Attachment size report: the UploadingAttachments progress event now
   carries 'Attachments: N files, X KB' plus the filtered/masked marker.
5. SnapshotFilter invariants exposed a REAL leak: root-level bin/obj
   folders' children share the folder's marker column, so the depth <=
   pop consumed the exclusion on the first child. Folder/file lines now
   follow different pop rules (siblings pop at <=, files drop while
   covered at >=); nested same-name, case differences and near names
   pinned by tests.
6. MessageCopyButton reported by keyless doctor (NotApplicableNow when no
   assistant message is visible).
7. Prompt-injection tests already existed (NOT REPRODUCED).
8. /newchat new-chat-URL test already existed (NOT REPRODUCED).
KA_CANCELLED documented in agentscript-spec.md (consistency test caught
it). 504 passing.

Subject: [PATCH 098/102] The application version comes from one place:
 Directory.Build.props

Program.cs hardcoded SetApplicationVersion("1.0.0") while the version
also lived in the CLI csproj - two sources that could drift. Now:
 lives in Directory.Build.props (inherited by the csproj), the
csproj's own  is removed, Program.cs reports the assembly
version (major.minor.patch, fallback 0.0.0), and publish.ps1 reads and
bumps  in Directory.Build.props (Get/Set-BuildPropsVersion)
instead of the csproj. DocsConsistencyTests.VersionMatchesDirectoryBuildProps
compares the props version with the built assembly version and asserts
the csproj carries no second . 505 passing.

Subject: [PATCH 099/102] Make publish.ps1 safe: SkipPush without a key, exact
 package name

(a) The NUGET_API_KEY check ran before packing and demanded the key even
with -SkipPush; it now happens only right before the push, so pack-only
runs work keyless.
(b) The package was picked as 'newest *.nupkg by LastWriteTime' - any
later touch of the artifacts folder could grab the wrong file. The exact
$ProjectName.$version.nupkg is selected now (missing = hard error), and
all push/cleanup references use that path.
(c) NOT REPRODUCED: dotnet pack already checks $LASTEXITCODE, summaries
the failure and stops via Write-Error before anything is deleted; the
existing delete-artifact-on-failed-push behavior is unchanged.
Verified live: two -SkipPush runs WITHOUT NUGET_API_KEY pack 1.0.0 and
auto-bump-pack 1.0.1, both exiting cleanly with no key demand.

 First run in a non-git workspace initializes the repository automatically (main branch, .NET .gitignore, initial commit — `Git.AutoInit`). Without git installed, a no-git mode runs file commands with backups only (no branch protection, no commits). Run `keyless chrome` once and log in to DeepSeek in the dedicated profile; since Chrome 136 the debug port only works with a dedicated profile, and the login persists there. Git decisions (dirty tree, branch choice) are presented as numbered menus — arrows, digits, Enter, Esc; no typed answers. Command risk tiers (ReadOnly/Build/Execute/Risky) control what runs automatically; risky commands always ask.

Subject: [PATCH 101/102] Copy-capture click loop: one combined wait, not 3s
 per fallback

The last sequential fallback waits are gone: both capture strategies'
Copy-control click loops (3s ClickAsync timeout per MessageCopyButton
fallback) now use ClickNewestCopyControlAsync - ONE visible-filtered
Or-wait over the whole fallback list carrying the same 3s-per-fallback
total budget, then a single click on the matched element. A click
failure is logged and reported as not-landed (Enter-safe), never a
per-fallback retry. Test: with the first two MessageCopyButton fallbacks
absent and the third visible, the capture clicks exactly the visible
fallback after ONE combined wait per strategy - zero ClickAsync calls on
the absent fallbacks. Stub lessons baked in: NSubstitute is last-config
wins, the Or-chain must be closed on its own stub, and
ILocator.EvaluateAsync is the 3-arg Task overload. 506
passing.
